A Sample Research Paper on Child Abuse

A research paper represents the pinnacle of academic investigation, a scholarly manuscript that encapsulates a detailed study, analysis, or argument based on extensive independent research. It is an embodiment of the researcher’s ability to synthesize a wealth of information, draw insightful conclusions, and contribute novel perspectives to the existing body of knowledge within a specific field. At its core, a research paper strives to push the boundaries of what is known, challenging existing theories and proposing new insights that could potentially reshape the understanding of a particular subject area.

The objective of writing a research paper is manifold, serving both educational and intellectual pursuits. Primarily, it aims to educate the author, providing a rigorous framework through which they engage deeply with a topic, hone their research and analytical skills, and learn the art of academic writing. Beyond personal growth, the research paper serves the broader academic community by contributing to the collective pool of knowledge, offering fresh perspectives, and stimulating further research. It is a medium through which scholars communicate ideas, findings, and theories, thereby fostering an ongoing dialogue that propels the advancement of science, humanities, and other fields of study.

Research papers can be categorized into various types, each with distinct objectives and methodologies. The most common types include:

Analytical Research Paper: This type focuses on analyzing different viewpoints represented in the scholarly literature or data. The author critically evaluates and interprets the information, aiming to provide a comprehensive understanding of the topic.
Argumentative or Persuasive Research Paper: Here, the author adopts a stance on a contentious issue and argues in favor of their position. The objective is to persuade the reader through evidence and logic that the author’s viewpoint is valid or preferable.
Experimental Research Paper: Often used in the sciences, this type documents the process, results, and implications of an experiment conducted by the author. It provides a detailed account of the methodology, data collected, analysis performed, and conclusions drawn.
Survey Research Paper: This involves collecting data from a set of respondents about their opinions, behaviors, or characteristics. The paper analyzes this data to draw conclusions about the population from which the sample was drawn.
Comparative Research Paper: This type involves comparing and contrasting different theories, policies, or phenomena. The aim is to highlight similarities and differences, thereby gaining a deeper understanding of the subjects under review.
Cause and Effect Research Paper: It explores the reasons behind specific actions, events, or conditions and the consequences that follow. The goal is to establish a causal relationship between variables.
Review Research Paper: This paper synthesizes existing research on a particular topic, offering a comprehensive analysis of the literature to identify trends, gaps, and consensus in the field.

Understanding the nuances and objectives of these various types of research papers is crucial for scholars and students alike, as it guides their approach to conducting and writing up their research. Each type demands a unique set of skills and perspectives, pushing the author to think critically and creatively about their subject matter. As the academic landscape continues to evolve, the research paper remains a fundamental tool for disseminating knowledge, encouraging innovation, and fostering a culture of inquiry and exploration.

A research paper is an academic piece of writing, so you need to follow all the requirements and standards. Otherwise, it will be impossible to get the high results. To make it easier for you, we have analyzed the structure and peculiarities of a sample research paper on the topic ‘Child Abuse’.

The paper includes 7300+ words, a detailed outline, citations are in APA formatting style, and bibliography with 28 sources.

To write any paper you need to write a great outline. This is the key to a perfect paper. When you organize your paper, it is easier for you to present the ideas logically, without jumping from one thought to another.

In the outline, you need to name all the parts of your paper. That is to say, an introduction, main body, conclusion, bibliography, some papers require abstract and proposal as well.

A good outline will serve as a guide through your paper making it easier for the reader to follow your ideas.

I. Introduction

Ii. estimates of child abuse: methodological limitations, iii. child abuse and neglect: the legalities, iv. corporal punishment versus child abuse, v. child abuse victims: the patterns, vi. child abuse perpetrators: the patterns, vii. explanations for child abuse, viii. consequences of child abuse and neglect, ix. determining abuse: how to tell whether a child is abused or neglected, x. determining abuse: interviewing children, xi. how can society help abused children and abusive families, introduction.

An introduction should include a thesis statement and the main points that you will discuss in the paper.

A thesis statement is one sentence in which you need to show your point of view. You will then develop this point of view through the whole piece of work:

‘The impact of child abuse affects more than one’s childhood, as the psychological and physical injuries often extend well into adulthood.’

Child abuse is a very real and prominent social problem today. The impact of child abuse affects more than one’s childhood, as the psychological and physical injuries often extend well into adulthood. Most children are defenseless against abuse, are dependent on their caretakers, and are unable to protect themselves from these acts.

Childhood serves as the basis for growth, development, and socialization. Throughout adolescence, children are taught how to become productive and positive, functioning members of society. Much of the socializing of children, particularly in their very earliest years, comes at the hands of family members. Unfortunately, the messages conveyed to and the actions against children by their families are not always the positive building blocks for which one would hope.

In 2008, the Children’s Defense Fund reported that each day in America, 2,421 children are confirmed as abused or neglected, 4 children are killed by abuse or neglect, and 78 babies die before their first birthday. These daily estimates translate into tremendous national figures. In 2006, caseworkers substantiated an estimated 905,000 reports of child abuse or neglect. Of these, 64% suffered neglect, 16% were physically abused, 9% were sexually abused, 7% were emotionally or psychologically maltreated, and 2% were medically neglected. In addition, 15% of the victims experienced “other” types of maltreatment such as abandonment, threats of harm to the child, and congenital drug addiction (National Child Abuse and Neglect Data System, 2006). Obviously, this problem is a substantial one.

In the main body, you dwell upon the topic of your paper. You provide your ideas and support them with evidence. The evidence include all the data and material you have found, analyzed and systematized. You can support your point of view with different statistical data, with surveys, and the results of different experiments. Your task is to show that your idea is right, and make the reader interested in the topic.

In this example, a writer analyzes the issue of child abuse: different statistical data, controversies regarding the topic, examples of the problem and the consequences.

Several issues arise when considering the amount of child abuse that occurs annually in the United States. Child abuse is very hard to estimate because much (or most) of it is not reported. Children who are abused are unlikely to report their victimization because they may not know any better, they still love their abusers and do not want to see them taken away (or do not themselves want to be taken away from their abusers), they have been threatened into not reporting, or they do not know to whom they should report their victimizations. Still further, children may report their abuse only to find the person to whom they report does not believe them or take any action on their behalf. Continuing to muddy the waters, child abuse can be disguised as legitimate injury, particularly because young children are often somewhat uncoordinated and are still learning to accomplish physical tasks, may not know their physical limitations, and are often legitimately injured during regular play. In the end, children rarely report child abuse; most often it is an adult who makes a report based on suspicion (e.g., teacher, counselor, doctor, etc.).

Even when child abuse is reported, social service agents and investigators may not follow up or substantiate reports for a variety of reasons. Parents can pretend, lie, or cover up injuries or stories of how injuries occurred when social service agents come to investigate. Further, there is not always agreement about what should be counted as abuse by service providers and researchers. In addition, social service agencies/agents have huge caseloads and may only be able to deal with the most serious forms of child abuse, leaving the more “minor” forms of abuse unsupervised and unmanaged (and uncounted in the statistical totals).

While most laws about child abuse and neglect fall at the state levels, federal legislation provides a foundation for states by identifying a minimum set of acts and behaviors that define child abuse and neglect. The Federal Child Abuse Prevention and Treatment Act (CAPTA), which stems from the Keeping Children and Families Safe Act of 2003, defines child abuse and neglect as, at minimum, “(1) any recent act or failure to act on the part of a parent or caretaker which results in death, serious physical or emotional harm, sexual abuse, or exploitation; or (2) an act or failure to act which presents an imminent risk or serious harm.”

Using these minimum standards, each state is responsible for providing its own definition of maltreatment within civil and criminal statutes. When defining types of child abuse, many states incorporate similar elements and definitions into their legal statutes. For example, neglect is often defined as failure to provide for a child’s basic needs. Neglect can encompass physical elements (e.g., failure to provide necessary food or shelter, or lack of appropriate supervision), medical elements (e.g., failure to provide necessary medical or mental health treatment), educational elements (e.g., failure to educate a child or attend to special educational needs), and emotional elements (e.g., inattention to a child’s emotional needs, failure to provide psychological care, or permitting the child to use alcohol or other drugs). Failure to meet needs does not always mean a child is neglected, as situations such as poverty, cultural values, and community standards can influence the application of legal statutes. In addition, several states distinguish between failure to provide based on financial inability and failure to provide for no apparent financial reason.

Statutes on physical abuse typically include elements of physical injury (ranging from minor bruises to severe fractures or death) as a result of punching, beating, kicking, biting, shaking, throwing, stabbing, choking, hitting (with a hand, stick, strap, or other object), burning, or otherwise harming a child. Such injury is considered abuse regardless of the intention of the caretaker. In addition, many state statutes include allowing or encouraging another person to physically harm a child (such as noted above) as another form of physical abuse in and of itself. Sexual abuse usually includes activities by a parent or caretaker such as fondling a child’s genitals, penetration, incest, rape, sodomy, indecent exposure, and exploitation through prostitution or the production of pornographic materials.

Finally, emotional or psychological abuse typically is defined as a pattern of behavior that impairs a child’s emotional development or sense of self-worth. This may include constant criticism, threats, or rejection, as well as withholding love, support, or guidance. Emotional abuse is often the most difficult to prove and, therefore, child protective services may not be able to intervene without evidence of harm to the child. Some states suggest that harm may be evidenced by an observable or substantial change in behavior, emotional response, or cognition, or by anxiety, depression, withdrawal, or aggressive behavior. At a practical level, emotional abuse is almost always present when other types of abuse are identified.

Some states include an element of substance abuse in their statutes on child abuse. Circumstances that can be considered substance abuse include (a) the manufacture of a controlled substance in the presence of a child or on the premises occupied by a child (Colorado, Indiana, Iowa, Montana, South Dakota, Tennessee, and Virginia); (b) allowing a child to be present where the chemicals or equipment for the manufacture of controlled substances are used (Arizona, New Mexico); (c) selling, distributing, or giving drugs or alcohol to a child (Florida, Hawaii, Illinois, Minnesota, and Texas); (d) use of a controlled substance by a caregiver that impairs the caregiver’s ability to adequately care for the child (Kentucky, New York, Rhode Island, and Texas); and (e) exposure of the child to drug paraphernalia (North Dakota), the criminal sale or distribution of drugs (Montana, Virginia), or drug-related activity (District of Columbia).

One of the most difficult issues with which the U.S. legal system must contend is that of allowing parents the right to use corporal punishment when disciplining a child, while not letting them cross over the line into the realm of child abuse. Some parents may abuse their children under the guise of discipline, and many instances of child abuse arise from angry parents who go too far when disciplining their children with physical punishment. Generally, state statutes use terms such as “reasonable discipline of a minor,” “causes only temporary, short-term pain,” and may cause “the potential for bruising” but not “permanent damage, disability, disfigurement or injury” to the child as ways of indicating the types of discipline behaviors that are legal. However, corporal punishment that is “excessive,” “malicious,” “endangers the bodily safety of,” or is “an intentional infliction of injury” is not allowed under most state statutes (e.g., state of Florida child abuse statute).

Most research finds that the use of physical punishment (most often spanking) is not an effective method of discipline. The literature on this issue tends to find that spanking stops misbehavior, but no more effectively than other firm measures. Further, it seems to hinder rather than improve general compliance/obedience (particularly when the child is not in the presence of the punisher). Researchers have also explained why physical punishment is not any more effective at gaining child compliance than nonviolent forms of discipline. Some of the problems that arise when parents use spanking or other forms of physical punishment include the fact that spanking does not teach what children should do, nor does it provide them with alternative behavior options should the circumstance arise again. Spanking also undermines reasoning, explanation, or other forms of parental instruction because children cannot learn, reason, or problem solve well while experiencing threat, pain, fear, or anger. Further, the use of physical punishment is inconsistent with nonviolent principles, or parental modeling. In addition, the use of spanking chips away at the bonds of affection between parents and children, and tends to induce resentment and fear. Finally, it hinders the development of empathy and compassion in children, and they do not learn to take responsibility for their own behavior (Pitzer, 1997).

One of the biggest problems with the use of corporal punishment is that it can escalate into much more severe forms of violence. Usually, parents spank because they are angry (and somewhat out of control) and they can’t think of other ways to discipline. When parents are acting as a result of emotional triggers, the notion of discipline is lost while punishment and pain become the foci.

In 2006, of the children who were found to be victims of child abuse, nearly 75% of them were first-time victims (or had not come to the attention of authorities prior). A slight majority of child abuse victims were girls—51.5%, compared to 48% of abuse victims being boys. The younger the child, the more at risk he or she is for child abuse and neglect victimization. Specifically, the rate for infants (birth to 1 year old) was approximately 24 per 1,000 children of the same age group. The victimization rate for children 1–3 years old was 14 per 1,000 children of the same age group. The abuse rate for children aged 4– 7 years old declined further to 13 per 1,000 children of the same age group. African American, American Indian, and Alaska Native children, as well as children of multiple races, had the highest rates of victimization. White and Latino children had lower rates, and Asian children had the lowest rates of child abuse and neglect victimization. Regarding living arrangements, nearly 27% of victims were living with a single mother, 20% were living with married parents, while 22% were living with both parents but the marital status was unknown. (This reporting element had nearly 40% missing data, however.) Regarding disability, nearly 8% of child abuse victims had some degree of mental retardation, emotional disturbance, visual or hearing impairment, learning disability, physical disability, behavioral problems, or other medical problems. Unfortunately, data indicate that for many victims, the efforts of the child protection services system were not successful in preventing subsequent victimization. Children who had been prior victims of maltreatment were 96% more likely to experience another occurrence than those who were not prior victims. Further, child victims who were reported to have a disability were 52% more likely to experience recurrence than children without a disability. Finally, the oldest victims (16–21 years of age) were the least likely to experience a recurrence, and were 51% less likely to be victimized again than were infants (younger than age 1) (National Child Abuse and Neglect Data System, 2006).

Child fatalities are the most tragic consequence of maltreatment. Yet, each year, children die from abuse and neglect. In 2006, an estimated 1,530 children in the United States died due to abuse or neglect. The overall rate of child fatalities was 2 deaths per 100,000 children. More than 40% of child fatalities were attributed to neglect, but physical abuse also was a major contributor. Approximately 78% of the children who died due to child abuse and neglect were younger than 4 years old, and infant boys (younger than 1) had the highest rate of fatalities at 18.5 deaths per 100,000 boys of the same age in the national population. Infant girls had a rate of 14.7 deaths per 100,000 girls of the same age (National Child Abuse and Neglect Data System, 2006).

One question to be addressed regarding child fatalities is why infants have such a high rate of death when compared to toddlers and adolescents. Children under 1 year old pose an immense amount of responsibility for their caretakers: they are completely dependent and need constant attention. Children this age are needy, impulsive, and not amenable to verbal control or effective communication. This can easily overwhelm vulnerable parents. Another difficulty associated with infants is that they are physically weak and small. Injuries to infants can be fatal, while similar injuries to older children might not be. The most common cause of death in children less than 1 year is cerebral trauma (often the result of shaken-baby syndrome). Exasperated parents can deliver shakes or blows without realizing how little it takes to cause irreparable or fatal damage to an infant. Research informs us that two of the most common triggers for fatal child abuse are crying that will not cease and toileting accidents. Both of these circumstances are common in infants and toddlers whose only means of communication often is crying, and who are limited in mobility and cannot use the toilet. Finally, very young children cannot assist in injury diagnoses. Children who have been injured due to abuse or neglect often cannot communicate to medical professionals about where it hurts, how it hurts, and so forth. Also, nonfatal injuries can turn fatal in the absence of care by neglectful parents or parents who do not want medical professionals to possibly identify an injury as being the result of abuse.

Estimates reveal that nearly 80% of perpetrators of child abuse were parents of the victim. Other relatives accounted for nearly 7%, and unmarried partners of parents made up 4% of perpetrators. Of those perpetrators that were parents, over 90% were biological parents, 4% were stepparents, and 0.7% were adoptive parents. Of this group, approximately 58% of perpetrators were women and 42% were men. Women perpetrators are typically younger than men. The average age for women abusers was 31 years old, while for men the average was 34 years old. Forty percent of women who abused were younger than 30 years of age, compared with 33% of men being under 30. The racial distribution of perpetrators is similar to that of victims. Fifty-four percent were white, 21% were African American, and 20% were Hispanic/Latino (National Child Abuse and Neglect Data System, 2006).

There are many factors that are associated with child abuse. Some of the more common/well-accepted explanations are individual pathology, parent–child interaction, past abuse in the family (or social learning), situational factors, and cultural support for physical punishment along with a lack of cultural support for helping parents here in the United States.

The first explanation centers on the individual pathology of a parent or caretaker who is abusive. This theory focuses on the idea that people who abuse their children have something wrong with their individual personality or biological makeup. Such psychological pathologies may include having anger control problems; being depressed or having post-partum depression; having a low tolerance for frustration (e.g., children can be extremely frustrating: they don’t always listen; they constantly push the line of how far they can go; and once the line has been established, they are constantly treading on it to make sure it hasn’t moved. They are dependent and self-centered, so caretakers have very little privacy or time to themselves); being rigid (e.g., having no tolerance for differences—for example, what if your son wanted to play with dolls? A rigid father would not let him, laugh at him for wanting to, punish him when he does, etc.); having deficits in empathy (parents who cannot put themselves in the shoes of their children cannot fully understand what their children need emotionally); or being disorganized, inefficient, and ineffectual. (Parents who are unable to manage their own lives are unlikely to be successful at managing the lives of their children, and since many children want and need limits, these parents are unable to set them or adhere to them.)

Biological pathologies that may increase the likelihood of someone becoming a child abuser include having substance abuse or dependence problems, or having persistent or reoccurring physical health problems (especially health problems that can be extremely painful and can cause a person to become more self-absorbed, both qualities that can give rise to a lack of patience, lower frustration tolerance, and increased stress).

The second explanation for child abuse centers on the interaction between the parent and the child, noting that certain types of parents are more likely to abuse, and certain types of children are more likely to be abused, and when these less-skilled parents are coupled with these more difficult children, child abuse is the most likely to occur. Discussion here focuses on what makes a parent less skilled, and what makes a child more difficult. Characteristics of unskilled parents are likely to include such traits as only pointing out what children do wrong and never giving any encouragement for good behavior, and failing to be sensitive to the emotional needs of children. Less skilled parents tend to have unrealistic expectations of children. They may engage in role reversal— where the parents make the child take care of them—and view the parent’s happiness and well-being as the responsibility of the child. Some parents view the parental role as extremely stressful and experience little enjoyment from being a parent. Finally, less-skilled parents tend to have more negative perceptions regarding their child(ren). For example, perhaps the child has a different shade of skin than they expected and this may disappoint or anger them, they may feel the child is being manipulative (long before children have this capability), or they may view the child as the scapegoat for all the parents’ or family’s problems. Theoretically, parents with these characteristics would be more likely to abuse their children, but if they are coupled with having a difficult child, they would be especially likely to be abusive. So, what makes a child more difficult? Certainly, through no fault of their own, children may have characteristics that are associated with child care that is more demanding and difficult than in the “normal” or “average” situation. Such characteristics can include having physical and mental disabilities (autism, attention deficit hyperactivity disorder [ADHD], hyperactivity, etc.); the child may be colicky, frequently sick, be particularly needy, or cry more often. In addition, some babies are simply unhappier than other babies for reasons that cannot be known. Further, infants are difficult even in the best of circumstances. They are unable to communicate effectively, and they are completely dependent on their caretakers for everything, including eating, diaper changing, moving around, entertainment, and emotional bonding. Again, these types of children, being more difficult, are more likely to be victims of child abuse.

Nonetheless, each of these types of parents and children alone cannot explain the abuse of children, but it is the interaction between them that becomes the key. Unskilled parents may produce children that are happy and not as needy, and even though they are unskilled, they do not abuse because the child takes less effort. At the same time, children who are more difficult may have parents who are skilled and are able to handle and manage the extra effort these children take with aplomb. However, risks for child abuse increase when unskilled parents must contend with difficult children.

Social learning or past abuse in the family is a third common explanation for child abuse. Here, the theory concentrates not only on what children learn when they see or experience violence in their homes, but additionally on what they do not learn as a result of these experiences. Social learning theory in the context of family violence stresses that if children are abused or see abuse (toward siblings or a parent), those interactions and violent family members become the representations and role models for their future familial interactions. In this way, what children learn is just as important as what they do not learn. Children who witness or experience violence may learn that this is the way parents deal with children, or that violence is an acceptable method of child rearing and discipline. They may think when they become parents that “violence worked on me when I was a child, and I turned out fine.” They may learn unhealthy relationship interaction patterns; children may witness the negative interactions of parents and they may learn the maladaptive or violent methods of expressing anger, reacting to stress, or coping with conflict.

What is equally as important, though, is that they are unlikely to learn more acceptable and nonviolent ways of rearing children, interacting with family members, and working out conflict. Here it may happen that an adult who was abused as a child would like to be nonviolent toward his or her own children, but when the chips are down and the child is misbehaving, this abused-child-turned-adult does not have a repertoire of nonviolent strategies to try. This parent is more likely to fall back on what he or she knows as methods of discipline.

Something important to note here is that not all abused children grow up to become abusive adults. Children who break the cycle were often able to establish and maintain one healthy emotional relationship with someone during their childhoods (or period of young adulthood). For instance, they may have received emotional support from a nonabusing parent, or they received social support and had a positive relationship with another adult during their childhood (e.g., teacher, coach, minister, neighbor, etc.). Abused children who participate in therapy during some period of their lives can often break the cycle of violence. In addition, adults who were abused but are able to form an emotionally supportive and satisfying relationship with a mate can make the transition to being nonviolent in their family interactions.

Moving on to a fourth familiar explanation for child abuse, there are some common situational factors that influence families and parents and increase the risks for child abuse. Typically, these are factors that increase family stress or social isolation. Specifically, such factors may include receiving public assistance or having low socioeconomic status (a combination of low income and low education). Other factors include having family members who are unemployed, underemployed (working in a job that requires lower qualifications than an individual possesses), or employed only part time. These financial difficulties cause great stress for families in meeting the needs of the individual members. Other stress-inducing familial characteristics are single-parent households and larger family size. Finally, social isolation can be devastating for families and family members. Having friends to talk to, who can be relied upon, and with whom kids can be dropped off occasionally is tremendously important for personal growth and satisfaction in life. In addition, social isolation and stress can cause individuals to be quick to lose their tempers, as well as cause people to be less rational in their decision making and to make mountains out of mole hills. These situations can lead families to be at greater risk for child abuse.

Finally, cultural views and supports (or lack thereof) can lead to greater amounts of child abuse in a society such as the United States. One such cultural view is that of societal support for physical punishment. This is problematic because there are similarities between the way criminals are dealt with and the way errant children are handled. The use of capital punishment is advocated for seriously violent criminals, and people are quick to use such idioms as “spare the rod and spoil the child” when it comes to the discipline or punishment of children. In fact, it was not until quite recently that parenting books began to encourage parents to use other strategies than spanking or other forms of corporal punishment in the discipline of their children. Only recently, the American Academy of Pediatrics has come out and recommended that parents do not spank or use other forms of violence on their children because of the deleterious effects such methods have on youngsters and their bonds with their parents. Nevertheless, regardless of recommendations, the culture of corporal punishment persists.

Another cultural view in the United States that can give rise to greater incidents of child abuse is the belief that after getting married, couples of course should want and have children. Culturally, Americans consider that children are a blessing, raising kids is the most wonderful thing a person can do, and everyone should have children. Along with this notion is the idea that motherhood is always wonderful; it is the most fulfilling thing a woman can do; and the bond between a mother and her child is strong, glorious, and automatic—all women love being mothers. Thus, culturally (and theoretically), society nearly insists that married couples have children and that they will love having children. But, after children are born, there is not much support for couples who have trouble adjusting to parenthood, or who do not absolutely love their new roles as parents. People look askance at parents who need help, and cannot believe parents who say anything negative about parenthood. As such, theoretically, society has set up a situation where couples are strongly encouraged to have kids, are told they will love kids, but then society turns a blind or disdainful eye when these same parents need emotional, financial, or other forms of help or support. It is these types of cultural viewpoints that increase the risks for child abuse in society.

The consequences of child abuse are tremendous and long lasting. Research has shown that the traumatic experience of childhood abuse is life changing. These costs may surface during adolescence, or they may not become evident until abused children have grown up and become abusing parents or abused spouses. Early identification and treatment is important to minimize these potential long-term effects. Whenever children say they have been abused, it is imperative that they be taken seriously and their abuse be reported. Suspicions of child abuse must be reported as well. If there is a possibility that a child is or has been abused, an investigation must be conducted.

Children who have been abused may exhibit traits such as the inability to love or have faith in others. This often translates into adults who are unable to establish lasting and stable personal relationships. These individuals have trouble with physical closeness and touching as well as emotional intimacy and trust. Further, these qualities tend to cause a fear of entering into new relationships, as well as the sabotaging of any current ones.

Psychologically, children who have been abused tend to have poor self-images or are passive, withdrawn, or clingy. They may be angry individuals who are filled with rage, anxiety, and a variety of fears. They are often aggressive, disruptive, and depressed. Many abused children have flashbacks and nightmares about the abuse they have experienced, and this may cause sleep problems as well as drug and alcohol problems. Posttraumatic stress disorder (PTSD) and antisocial personality disorder are both typical among maltreated children. Research has also shown that most abused children fail to reach “successful psychosocial functioning,” and are thus not resilient and do not resume a “normal life” after the abuse has ended.

Socially (and likely because of these psychological injuries), abused children have trouble in school, will have difficulty getting and remaining employed, and may commit a variety of illegal or socially inappropriate behaviors. Many studies have shown that victims of child abuse are likely to participate in high-risk behaviors such as alcohol or drug abuse, the use of tobacco, and high-risk sexual behaviors (e.g., unprotected sex, large numbers of sexual partners). Later in life, abused children are more likely to have been arrested and homeless. They are also less able to defend themselves in conflict situations and guard themselves against repeated victimizations.

Medically, abused children likely will experience health problems due to the high frequency of physical injuries they receive. In addition, abused children experience a great deal of emotional turmoil and stress, which can also have a significant impact on their physical condition. These health problems are likely to continue occurring into adulthood. Some of these longer-lasting health problems include headaches; eating problems; problems with toileting; and chronic pain in the back, stomach, chest, and genital areas. Some researchers have noted that abused children may experience neurological impairment and problems with intellectual functioning, while others have found a correlation between abuse and heart, lung, and liver disease, as well as cancer (Thomas, 2004).

Victims of sexual abuse show an alarming number of disturbances as adults. Some dislike and avoid sex, or experience sexual problems or disorders, while other victims appear to enjoy sexual activities that are self-defeating or maladaptive—normally called “dysfunctional sexual behavior”—and have many sexual partners.

Abused children also experience a wide variety of developmental delays. Many do not reach physical, cognitive, or emotional developmental milestones at the typical time, and some never accomplish what they are supposed to during childhood socialization. In the next section, these developmental delays are discussed as a means of identifying children who may be abused.

There are two primary ways of identifying children who are abused: spotting and evaluating physical injuries, and detecting and appraising developmental delays. Distinguishing physical injuries due to abuse can be difficult, particularly among younger children who are likely to get hurt or receive injuries while they are playing and learning to become ambulatory. Nonetheless, there are several types of wounds that children are unlikely to give themselves during their normal course of play and exploration. These less likely injuries may signal instances of child abuse.

While it is true that children are likely to get bruises, particularly when they are learning to walk or crawl, bruises on infants are not normal. Also, the back of the legs, upper arms, or on the chest, neck, head, or genitals are also locations where bruises are unlikely to occur during normal childhood activity. Further, bruises with clean patterns, like hand prints, buckle prints, or hangers (to name a few), are good examples of the types of bruises children do not give themselves.

Another area of physical injury where the source of the injury can be difficult to detect is fractures. Again, children fall out of trees, or crash their bikes, and can break limbs. These can be normal parts of growing up. However, fractures in infants less than 12 months old are particularly suspect, as infants are unlikely to be able to accomplish the types of movement necessary to actually break a leg or an arm. Further, multiple fractures, particularly more than one on a bone, should be examined more closely. Spiral or torsion fractures (when the bone is broken by twisting) are suspect because when children break their bones due to play injuries, the fractures are usually some other type (e.g., linear, oblique, compacted). In addition, when parents don’t know about the fracture(s) or how it occurred, abuse should be considered, because when children get these types of injuries, they need comfort and attention.

Head and internal injuries are also those that may signal abuse. Serious blows to the head cause internal head injuries, and this is very different from the injuries that result from bumping into things. Abused children are also likely to experience internal injuries like those to the abdomen, liver, kidney, and bladder. They may suffer a ruptured spleen, or intestinal perforation. These types of damages rarely happen by accident.

Burns are another type of physical injury that can happen by accident or by abuse. Nevertheless, there are ways to tell these types of burn injuries apart. The types of burns that should be examined and investigated are those where the burns are in particular locations. Burns to the bottom of the feet, genitals, abdomen, or other inaccessible spots should be closely considered. Burns of the whole hand or those to the buttocks are also unlikely to happen as a result of an accident.

Turning to the detection and appraisal of developmental delays, one can more readily assess possible abuse by considering what children of various ages should be able to accomplish, than by noting when children are delayed and how many milestones on which they are behind schedule. Importantly, a few delays in reaching milestones can be expected, since children develop individually and not always according to the norm. Nonetheless, when children are abused, their development is likely to be delayed in numerous areas and across many milestones.

As children develop and grow, they should be able to crawl, walk, run, talk, control going to the bathroom, write, set priorities, plan ahead, trust others, make friends, develop a good self-image, differentiate between feeling and behavior, and get their needs met in appropriate ways. As such, when children do not accomplish these feats, their circumstances should be examined.

Infants who are abused or neglected typically develop what is termed failure to thrive syndrome. This syndrome is characterized by slow, inadequate growth, or not “filling out” physically. They have a pale, colorless complexion and dull eyes. They are not likely to spend much time looking around, and nothing catches their eyes. They may show other signs of lack of nutrition such as cuts, bruises that do not heal in a timely way, and discolored fingernails. They are also not trusting and may not cry much, as they are not expecting to have their needs met. Older infants may not have developed any language skills, or these developments are quite slow. This includes both verbal and nonverbal means of communication.

Toddlers who are abused often become hypervigilant about their environments and others’ moods. They are more outwardly focused than a typical toddler (who is quite self-centered) and may be unable to separate themselves as individuals, or consider themselves as distinct beings. In this way, abused toddlers cannot focus on tasks at hand because they are too concerned about others’ reactions. They don’t play with toys, have no interest in exploration, and seem unable to enjoy life. They are likely to accept losses with little reaction, and may have age-inappropriate knowledge of sex and sexual relations. Finally, toddlers, whether they are abused or not, begin to mirror their parents’ behaviors. Thus, toddlers who are abused may mimic the abuse when they are playing with dolls or “playing house.”

Developmental delays can also be detected among abused young adolescents. Some signs include the failure to learn cause and effect, since their parents are so inconsistent. They have no energy for learning and have not developed beyond one- or two-word commands. They probably cannot follow complicated directions (such as two to three tasks per instruction), and they are unlikely to be able to think for themselves. Typically, they have learned that failure is totally unacceptable, but they are more concerned with the teacher’s mood than with learning and listening to instruction. Finally, they are apt to have been inadequately toilet trained and thus may be unable to control their bladders.

Older adolescents, because they are likely to have been abused for a longer period of time, continue to get further and further behind in their developmental achievements. Abused children this age become family nurturers. They take care of their parents and cater to their parents’ needs, rather than the other way around. In addition, they probably take care of any younger siblings and do the household chores. Because of these default responsibilities, they usually do not participate in school activities; they frequently miss days at school; and they have few, if any, friends. Because they have become so hypervigilant and have increasingly delayed development, they lose interest in and become disillusioned with education. They develop low self-esteem and little confidence, but seem old for their years. Children this age who are abused are still likely to be unable to control their bladders and may have frequent toileting accidents.

Other developmental delays can occur and be observed in abused and neglected children of any age. For example, malnutrition and withdrawal can be noticed in infants through teenagers. Maltreated children frequently have persistent or untreated illnesses, and these can become permanent disabilities if medical conditions go untreated for a long enough time. Another example can be the consequences of neurological damage. Beyond being a medical issue, this type of damage can cause problems with social behavior and impulse control, which, again, can be discerned in various ages of children.

Once child abuse is suspected, law enforcement officers, child protection workers, or various other practitioners may need to interview the child about the abuse or neglect he or she may have suffered. Interviewing children can be extremely difficult because children at various stages of development can remember only certain parts or aspects of the events in their lives. Also, interviewers must be careful that they do not put ideas or answers into the heads of the children they are interviewing. There are several general recommendations when interviewing children about the abuse they may have experienced. First, interviewers must acknowledge that even when children are abused, they likely still love their parents. They do not want to be taken away from their parents, nor do they want to see their parents get into trouble. Interviewers must not blame the parents or be judgmental about them or the child’s family. Beyond that, interviews should take place in a safe, neutral location. Interviewers can use dolls and role-play to help children express the types of abuse of which they may be victims.

Finally, interviewers must ask age-appropriate questions. For example, 3-year-olds can probably only answer questions about what happened and who was involved. Four- to five-year-olds can also discuss where the incidents occurred. Along with what, who, and where, 6- to 8-year-olds can talk about the element of time, or when the abuse occurred. Nine- to 10-year-olds are able to add commentary about the number of times the abuse occurred. Finally, 11-year-olds and older children can additionally inform interviewers about the circumstances of abusive instances.

A conclusion is not a summary of what a writer has already mentioned. On the contrary, it is the last point made. Taking every detail of the investigation, the researcher makes the concluding point. In this part of a paper, you need to put a full stop in your research. You need to persuade the reader in your opinion.

Never add any new information in the conclusion. You can present solutions to the problem and you dwell upon the results, but only if this information has been already mentioned in the main body.

Child advocates recommend a variety of strategies to aid families and children experiencing abuse. These recommendations tend to focus on societal efforts as well as more individual efforts. One common strategy advocated is the use of public service announcements that encourage individuals to report any suspected child abuse. Currently, many mandatory reporters (those required by law to report abuse such as teachers, doctors, and social service agency employees) and members of communities feel that child abuse should not be reported unless there is substantial evidence that abuse is indeed occurring. Child advocates stress that this notion should be changed, and that people should report child abuse even if it is only suspected. Public service announcements should stress that if people report suspected child abuse, the worst that can happen is that they might be wrong, but in the grander scheme of things that is really not so bad.

Child advocates also stress that greater interagency cooperation is needed. This cooperation should be evident between women’s shelters, child protection agencies, programs for at-risk children, medical agencies, and law enforcement officers. These agencies typically do not share information, and if they did, more instances of child abuse would come to the attention of various authorities and could be investigated and managed. Along these lines, child protection agencies and programs should receive more funding. When budgets are cut, social services are often the first things to go or to get less financial support. Child advocates insist that with more resources, child protection agencies could hire more workers, handle more cases, conduct more investigations, and follow up with more children and families.

Continuing, more educational efforts must be initiated about issues such as punishment and discipline styles and strategies; having greater respect for children; as well as informing the community about what child abuse is, and how to recognize it. In addition, Americans must alter the cultural orientation about child bearing and child rearing. Couples who wish to remain child-free must be allowed to do so without disdain. And, it must be acknowledged that raising children is very difficult, is not always gloriously wonderful, and that parents who seek help should be lauded and not criticized. These kinds of efforts can help more children to be raised in nonviolent, emotionally satisfying families, and thus become better adults.

Bibliography

When you write a paper, make sure you are aware of all the formatting requirements. Incorrect formatting can lower your mark, so do not underestimate the importance of this part.

Organizing your bibliography is quite a tedious and time-consuming task. Still, you need to do it flawlessly. For this reason, analyze all the standards you need to meet or ask professionals to help you with it. All the comas, colons, brackets etc. matter. They truly do.

Using Biometrics to Evaluate Visual Design

Jane Lisa Dekker

Art Department, Northern California Valley State University

UXAD 272: Strategic Web Design

Professor Juan Liu, PhD

January 29, 2020

A vast amount of research has been conducted regarding the importance of visual design, and its role as a mediator of user’s experience when browsing a site or interacting with an interface. In the literature, visual design is one aspect of website quality. Jones and Kim (2010) define website quality as “the perceived quality of a retail website that involves a [user’s] perceptions of the retailer’s website and comprises consumer reactions towards such attributes as information, entertainment/enjoyment, usability, transaction capabilities, and design aesthetics” (p. 632). They further examined the impact web quality and retail brand trust has on purchase intentions. Additional research examining e-commerce sites has shown web quality has an impact on both initial and continued purchase intention (Kuan, Bock, & Vathanophas, 2008), as well as consumer satisfaction (Lin, 2007). Moreso, research on the relationship between visual design and perceived usability (Stojmenovic, Pilgrim, & Lindgaard, 2014) has revealed a positive correlation between the two. As users’ ratings of visual quality increase, their ratings of perceived usability follows a similar trend. Although this research spans various domains, the reliance on self-report measures to gauge concepts like visual design and web quality is prevalent throughout much of the literature.

Although some self-report scales are validated within the literature, there are still issues with the use of self-report questionnaires. One is the reliance on the honesty of the participant. This tends to be more of an issue in studies related to questionnaires that measure characteristics of the participant, rather than objective stimuli. More relevant to this study is the issue of introspection and memory. Surveys are often distributed after a task is completed, and its accuracy is dependent on the ability of the participant to remember their experience during the study. Multiple research studies have shown that human memory is far from static. This can

be dangerous if a researcher chooses to solely rely on self-report methods to test a hypothesis. We believe these self-report methods in tandem with biometric methods can help ensure the validity of the questionnaires, and provide information beyond the scope of self-report scales.

Research Questions

We know from previous research that the quality of websites mediates many aspects of e-commerce, and provides insight as to how consumers view the webpages in general. However, simply knowing a webpage is perceived as lower quality doesn’t give insight as to what aspects of a page are disliked by a user. Additionally, it’s possible that the user is misremembering aspects of the webpage or being dishonest in their assessment. Using eye tracking metrics, galvanic skin response, and facial expression measures in tandem with a scale aimed at measuring visual design quality has a couple of identifiable benefits. Using both can potentially identify patterns amongst the biometric measures and the questionnaire, which would strengthen the validity of the results. More so, the eye tracking data has the potential to identify patterns amongst websites of lower or higher quality.

If found, these patterns can be used to evaluate particular aspects of a page that are impacting the quality of a webpage. Overall, we are interested in answering two questions:

Research Question 1 : Can attitudinal changes regarding substantial website redesigns be captured using biometric measures?

Research Question 2 : How do biometric measures correlate with self-reported measures of visual appeal?

Answering these questions has the potential to provide a method of justification for design changes, ranging from minor tweak to complete rebrands. There is not an easy way for companies to quantitatively analyze visual design decisions. A method for doing so would help companies evaluate visual designs before implementation in order to cost-justify them. To this end, we hope to demonstrate that biometric measurements can be used with questionnaires to verify and validate potential design changes a company or organization might want to implement.

By examining data from test subjects during a brief exposure to several websites, we hoped to explore the relationship between the self-reported evaluation of visual design quality and key biometric measurements of a subject’s emotional valence and arousal. Subjects were exposed to ten pairs of websites before and after a substantial visual design change and asked to evaluate the website based on their initial impressions of the site’s visual design quality using the VisAWI-S scale, as shown in Table 1.

During this assessment we collected GSR, facial expressions (limited by errors in initial study configuration), pupillary response, and fixation data using iMotions software coupled with a Tobii eye tracker, Shimmer GSR device, and Affdex facial expression analysis toolkit. This data was analyzed, in Table 2, to discover relationships between the independent and dependent variables, as well as relationships between certain dependent variables.

How to Write a Research Paper

Use the links below to jump directly to any section of this guide:

Research Paper Fundamentals

How to choose a topic or question, how to create a working hypothesis or thesis, common research paper methodologies, how to gather and organize evidence , how to write an outline for your research paper, how to write a rough draft, how to revise your draft, how to produce a final draft, resources for teachers .

It is not fair to say that no one writes anymore. Just about everyone writes text messages, brief emails, or social media posts every single day. Yet, most people don't have a lot of practice with the formal, organized writing required for a good academic research paper. This guide contains links to a variety of resources that can help demystify the process. Some of these resources are intended for teachers; they contain exercises, activities, and teaching strategies. Other resources are intended for direct use by students who are struggling to write papers, or are looking for tips to make the process go more smoothly.

The resources in this section are designed to help students understand the different types of research papers, the general research process, and how to manage their time. Below, you'll find links from university writing centers, the trusted Purdue Online Writing Lab, and more.

What is an Academic Research Paper?

"Genre and the Research Paper" (Purdue OWL)

There are different types of research papers. Different types of scholarly questions will lend themselves to one format or another. This is a brief introduction to the two main genres of research paper: analytic and argumentative.

"7 Most Popular Types of Research Papers" (Personal-writer.com)

This resource discusses formats that high school students commonly encounter, such as the compare and contrast essay and the definitional essay. Please note that the inclusion of this link is not an endorsement of this company's paid service.

How to Prepare and Plan Out Writing a Research Paper

Teachers can give their students a step-by-step guide like these to help them understand the different steps of the research paper process. These guides can be combined with the time management tools in the next subsection to help students come up with customized calendars for completing their papers.

"Ten Steps for Writing Research Papers" (American University)

This resource from American University is a comprehensive guide to the research paper writing process, and includes examples of proper research questions and thesis topics.

"Steps in Writing a Research Paper" (SUNY Empire State College)

This guide breaks the research paper process into 11 steps. Each "step" links to a separate page, which describes the work entailed in completing it.

How to Manage Time Effectively

The links below will help students determine how much time is necessary to complete a paper. If your sources are not available online or at your local library, you'll need to leave extra time for the Interlibrary Loan process. Remember that, even if you do not need to consult secondary sources, you'll still need to leave yourself ample time to organize your thoughts.

"Research Paper Planner: Timeline" (Baylor University)

This interactive resource from Baylor University creates a suggested writing schedule based on how much time a student has to work on the assignment.

"Research Paper Planner" (UCLA)

UCLA's library offers this step-by-step guide to the research paper writing process, which also includes a suggested planning calendar.

There's a reason teachers spend a long time talking about choosing a good topic. Without a good topic and a well-formulated research question, it is almost impossible to write a clear and organized paper. The resources below will help you generate ideas and formulate precise questions.

"How to Select a Research Topic" (Univ. of Michigan-Flint)

This resource is designed for college students who are struggling to come up with an appropriate topic. A student who uses this resource and still feels unsure about his or her topic should consult the course instructor for further personalized assistance.

"25 Interesting Research Paper Topics to Get You Started" (Kibin)

This resource, which is probably most appropriate for high school students, provides a list of specific topics to help get students started. It is broken into subsections, such as "paper topics on local issues."

"Writing a Good Research Question" (Grand Canyon University)

This introduction to research questions includes some embedded videos, as well as links to scholarly articles on research questions. This resource would be most appropriate for teachers who are planning lessons on research paper fundamentals.

"How to Write a Research Question the Right Way" (Kibin)

This student-focused resource provides more detail on writing research questions. The language is accessible, and there are embedded videos and examples of good and bad questions.

It is important to have a rough hypothesis or thesis in mind at the beginning of the research process. People who have a sense of what they want to say will have an easier time sorting through scholarly sources and other information. The key, of course, is not to become too wedded to the draft hypothesis or thesis. Just about every working thesis gets changed during the research process.

CrashCourse Video: "Sociology Research Methods" (YouTube)

Although this video is tailored to sociology students, it is applicable to students in a variety of social science disciplines. This video does a good job demonstrating the connection between the brainstorming that goes into selecting a research question and the formulation of a working hypothesis.

"How to Write a Thesis Statement for an Analytical Essay" (YouTube)

Students writing analytical essays will not develop the same type of working hypothesis as students who are writing research papers in other disciplines. For these students, developing the working thesis may happen as a part of the rough draft (see the relevant section below).

"Research Hypothesis" (Oakland Univ.)

This resource provides some examples of hypotheses in social science disciplines like Political Science and Criminal Justice. These sample hypotheses may also be useful for students in other soft social sciences and humanities disciplines like History.

When grading a research paper, instructors look for a consistent methodology. This section will help you understand different methodological approaches used in research papers. Students will get the most out of these resources if they use them to help prepare for conversations with teachers or discussions in class.

"Types of Research Designs" (USC)

A "research design," used for complex papers, is related to the paper's method. This resource contains introductions to a variety of popular research designs in the social sciences. Although it is not the most intuitive site to read, the information here is very valuable.

"Major Research Methods" (YouTube)

Although this video is a bit on the dry side, it provides a comprehensive overview of the major research methodologies in a format that might be more accessible to students who have struggled with textbooks or other written resources.

"Humanities Research Strategies" (USC)

This is a portal where students can learn about four methodological approaches for humanities papers: Historical Methodologies, Textual Criticism, Conceptual Analysis, and the Synoptic method.

"Selected Major Social Science Research Methods: Overview" (National Academies Press)

This appendix from the book Using Science as Evidence in Public Policy , printed by National Academies Press, introduces some methods used in social science papers.

"Organizing Your Social Sciences Research Paper: 6. The Methodology" (USC)

This resource from the University of Southern California's library contains tips for writing a methodology section in a research paper.

How to Determine the Best Methodology for You

Anyone who is new to writing research papers should be sure to select a method in consultation with their instructor. These resources can be used to help prepare for that discussion. They may also be used on their own by more advanced students.

"Choosing Appropriate Research Methodologies" (Palgrave Study Skills)

This friendly and approachable resource from Palgrave Macmillan can be used by students who are just starting to think about appropriate methodologies.

"How to Choose Your Research Methods" (NFER (UK))

This is another approachable resource students can use to help narrow down the most appropriate methods for their research projects.

The resources in this section introduce the process of gathering scholarly sources and collecting evidence. You'll find a range of material here, from introductory guides to advanced explications best suited to college students. Please consult the LitCharts How to Do Academic Research guide for a more comprehensive list of resources devoted to finding scholarly literature.

Students who have access to library websites with detailed research guides should start there, but people who do not have access to those resources can begin their search for secondary literature here.

"Gathering Appropriate Information" (Texas Gateway)

This resource from the Texas Gateway for online resources introduces students to the research process, and contains interactive exercises. The level of complexity is suitable for middle school, high school, and introductory college classrooms.

"An Overview of Quantitative and Qualitative Data Collection Methods" (NSF)

This PDF from the National Science Foundation goes into detail about best practices and pitfalls in data collection across multiple types of methodologies.

"Social Science Methods for Data Collection and Analysis" (Swiss FIT)

This resource is appropriate for advanced undergraduates or teachers looking to create lessons on research design and data collection. It covers techniques for gathering data via interviews, observations, and other methods.

"Collecting Data by In-depth Interviewing" (Leeds Univ.)

This resource contains enough information about conducting interviews to make it useful for teachers who want to create a lesson plan, but is also accessible enough for college juniors or seniors to make use of it on their own.

There is no "one size fits all" outlining technique. Some students might devote all their energy and attention to the outline in order to avoid the paper. Other students may benefit from being made to sit down and organize their thoughts into a lengthy sentence outline. The resources in this section include strategies and templates for multiple types of outlines.

"Topic vs. Sentence Outlines" (UC Berkeley)

This resource introduces two basic approaches to outlining: the shorter topic-based approach, and the longer, more detailed sentence-based approach. This resource also contains videos on how to develop paper paragraphs from the sentence-based outline.

"Types of Outlines and Samples" (Purdue OWL)

The Purdue Online Writing Lab's guide is a slightly less detailed discussion of different types of outlines. It contains several sample outlines.

"Writing An Outline" (Austin C.C.)

This resource from a community college contains sample outlines from an American history class that students can use as models.

"How to Structure an Outline for a College Paper" (YouTube)

This brief (sub-2 minute) video from the ExpertVillage YouTube channel provides a model of outline writing for students who are struggling with the idea.

"Outlining" (Harvard)

This is a good resource to consult after completing a draft outline. It offers suggestions for making sure your outline avoids things like unnecessary repetition.

As with outlines, rough drafts can take on many different forms. These resources introduce teachers and students to the various approaches to writing a rough draft. This section also includes resources that will help you cite your sources appropriately according to the MLA, Chicago, and APA style manuals.

"Creating a Rough Draft for a Research Paper" (Univ. of Minnesota)

This resource is useful for teachers in particular, as it provides some suggested exercises to help students with writing a basic rough draft.

Rough Draft Assignment (Duke of Definition)

This sample assignment, with a brief list of tips, was developed by a high school teacher who runs a very successful and well-reviewed page of educational resources.

"Creating the First Draft of Your Research Paper" (Concordia Univ.)

This resource will be helpful for perfectionists or procrastinators, as it opens by discussing the problem of avoiding writing. It also provides a short list of suggestions meant to get students writing.

Using Proper Citations

There is no such thing as a rough draft of a scholarly citation. These links to the three major citation guides will ensure that your citations follow the correct format. Please consult the LitCharts How to Cite Your Sources guide for more resources.

Chicago Manual of Style Citation Guide

Some call The Chicago Manual of Style , which was first published in 1906, "the editors' Bible." The manual is now in its 17th edition, and is popular in the social sciences, historical journals, and some other fields in the humanities.

APA Citation Guide

According to the American Psychological Association, this guide was developed to aid reading comprehension, clarity of communication, and to reduce bias in language in the social and behavioral sciences. Its first full edition was published in 1952, and it is now in its sixth edition.

MLA Citation Guide

The Modern Language Association style is used most commonly within the liberal arts and humanities. The MLA Style Manual and Guide to Scholarly Publishing was first published in 1985 and (as of 2008) is in its third edition.

Any professional scholar will tell you that the best research papers are made in the revision stage. No matter how strong your research question or working thesis, it is not possible to write a truly outstanding paper without devoting energy to revision. These resources provide examples of revision exercises for the classroom, as well as tips for students working independently.

"The Art of Revision" (Univ. of Arizona)

This resource provides a wealth of information and suggestions for both students and teachers. There is a list of suggested exercises that teachers might use in class, along with a revision checklist that is useful for teachers and students alike.

"Script for Workshop on Revision" (Vanderbilt University)

Vanderbilt's guide for leading a 50-minute revision workshop can serve as a model for teachers who wish to guide students through the revision process during classtime.

"Revising Your Paper" (Univ. of Washington)

This detailed handout was designed for students who are beginning the revision process. It discusses different approaches and methods for revision, and also includes a detailed list of things students should look for while they revise.

"Revising Drafts" (UNC Writing Center)

This resource is designed for students and suggests things to look for during the revision process. It provides steps for the process and has a FAQ for students who have questions about why it is important to revise.

Conferencing with Writing Tutors and Instructors

No writer is so good that he or she can't benefit from meeting with instructors or peer tutors. These resources from university writing, learning, and communication centers provide suggestions for how to get the most out of these one-on-one meetings.

"Getting Feedback" (UNC Writing Center)

Research Methodology for Investigating the Effectiveness of Cognitive Behavioral Therapy in Reducing Symptoms of Depression in Adults

Introduction:

The aim of this research is to investigate the effectiveness of cognitive-behavioral therapy (CBT) in reducing symptoms of depression in adults. To achieve this objective, a randomized controlled trial (RCT) will be conducted using a mixed-methods approach.

Research Design:

The study will follow a pre-test and post-test design with two groups: an experimental group receiving CBT and a control group receiving no intervention. The study will also include a qualitative component, in which semi-structured interviews will be conducted with a subset of participants to explore their experiences of receiving CBT.

Participants:

Participants will be recruited from community mental health clinics in the local area. The sample will consist of 100 adults aged 18-65 years old who meet the diagnostic criteria for major depressive disorder. Participants will be randomly assigned to either the experimental group or the control group.

Intervention :

The experimental group will receive 12 weekly sessions of CBT, each lasting 60 minutes. The intervention will be delivered by licensed mental health professionals who have been trained in CBT. The control group will receive no intervention during the study period.

Data Collection:

Quantitative data will be collected through the use of standardized measures such as the Beck Depression Inventory-II (BDI-II) and the Generalized Anxiety Disorder-7 (GAD-7). Data will be collected at baseline, immediately after the intervention, and at a 3-month follow-up. Qualitative data will be collected through semi-structured interviews with a subset of participants from the experimental group. The interviews will be conducted at the end of the intervention period, and will explore participants’ experiences of receiving CBT.

Data Analysis:

Quantitative data will be analyzed using descriptive statistics, t-tests, and mixed-model analyses of variance (ANOVA) to assess the effectiveness of the intervention. Qualitative data will be analyzed using thematic analysis to identify common themes and patterns in participants’ experiences of receiving CBT.

Ethical Considerations:

This study will comply with ethical guidelines for research involving human subjects. Participants will provide informed consent before participating in the study, and their privacy and confidentiality will be protected throughout the study. Any adverse events or reactions will be reported and managed appropriately.

Data Management:

All data collected will be kept confidential and stored securely using password-protected databases. Identifying information will be removed from qualitative data transcripts to ensure participants’ anonymity.

Limitations:

One potential limitation of this study is that it only focuses on one type of psychotherapy, CBT, and may not generalize to other types of therapy or interventions. Another limitation is that the study will only include participants from community mental health clinics, which may not be representative of the general population.

Conclusion:

This research aims to investigate the effectiveness of CBT in reducing symptoms of depression in adults. By using a randomized controlled trial and a mixed-methods approach, the study will provide valuable insights into the mechanisms underlying the relationship between CBT and depression. The results of this study will have important implications for the development of effective treatments for depression in clinical settings.

In order to propose a reliable method for assessing the safety condition for single-tower steel box girder Suspension bridges over the sea, a condition monitoring system is established by installing sensors on the bridge structure. The system is capable of gathering monitoring data that influence the safety status of the bridge. These include cable tension, load on the main tower and pylon, bearing displacement, wind direction, wind speed, and ambient temperature and humidity. Furthermore, an improved Analytic Hierarchy Process (AHP) algorithm is developed by integrating a hybrid triangular fuzzy number logic structure. This improvement, coupled with comprehensive fuzzy evaluation methods, improves the consistency, weight determination, and security evaluation capabilities of the AHP algorithm. Finally, taking the No.2 Channel Bridge as an example and based on the data collected by the health monitoring system, the application of the safety assessment method proposed in this paper provides favorable results in evaluating the overall safety status of the bridge in practical engineering applications. This provides a basis for management decisions by bridge maintenance departments. This project confirms that the research results can provide a reliable method for assessing the security status of relevant areas.

Introduction

With the in-depth implementation of the strategy to strengthen national transport, the development of transport infrastructure has entered a new phase of rapid development. It is expected that China could lead the world in the number of bridges by the 2030s 1 . As the service life of bridges increases, damage to various structures and components can have an impact on the safe operation of bridges. In some cases, the failure of a particular component can result in a complete loss of bridge safety. In order to be able to assess the safety status of bridges intuitively and quickly, it is usually necessary to carry out safety assessments. There are two main methods for assessing bridge safety: using bridge monitoring data and using manual inspections along with standardized criteria. Currently, the assessment and early warning of the safety status of bridge structures is largely carried out by installing sensors and monitoring devices on bridge structures. This enables long-term real-time monitoring of the operating status and relevant physical parameters of the bridge 2 , 3 . For single-tower steel box girder suspension bridges over the sea, traditional manual inspection methods suffer from subjectivity, low efficiency and high labor costs due to their high pylons and structural complexity, so they cannot meet maintenance requirements. Therefore, in order to capture the safety operation status of bridge structures in real time, it is particularly important to conduct safety status assessments for single-tower steel box girder suspension bridges over the sea using health monitoring systems.

Bao et al. 4 In order to carry out an effective risk assessment in the construction of long-span bridges and determine the optimal construction scheme using the Analytic Hierarchy Process, the AHP was integrated with the Gray Correlation method. They created a multi-level comprehensive assessment model and used the AHP to provide weights for the factors that influence the assessment indicators. Yang et al. 5 based on a comprehensive analysis of the safety factors associated with existing bridges crossing municipal roads, proposed a comprehensive fuzzy evaluation method of Analytic Hierarchy Process to evaluate the impact of road construction on the safety of existing bridges. Yang et al. 6 proposed a novel comprehensive condition assessment method that considers the uncertainty of the measured data intervals and the influence of conflicting measured data. By comparing the condition assessment results with the actual state of components or the entire bridge, they verified the advantages of the proposed method over existing AHP assessment methods and traditional combination methods. Liu et al. 7 presented a reliability assessment method for a precast reinforced concrete hollow slab bridge system considering damage to joint nodes based on an improved Analytic Hierarchy Process. Tan et al. 8 addressed the optimization selection problem of retrofit solutions for old bridges and introduced a decision method based on fuzzy Analytic Hierarchy Process weights and gray relational analysis. Lu et al. 9 proposed a method for risk assessment of Suspension bridges and cable systems based on cloud model, which effectively combines the randomness and uncertainty of risk information. Wang et al. 10 , 11 outlined the research trends in main cable safety assessment and emphasized the importance of improving the safety of main cables to ensure the structural safety of long-span, multi-tower suspension bridges. Andrić et al. 12 combined the Fuzzy Analytic Hierarchy Process (FAHP) with fuzzy knowledge representation and fuzzy logic techniques, proposing a novel framework for disaster risk assessment. This method proves its practicality and efficiency in analyzing and evaluating multi-hazard risks for bridges. Ji et al. 13 introduced a large-scale risk assessment method for complex bridge structures based on Delphi-enhanced Fuzzy Analytic Hierarchy Process (FAHP) factor analysis. The approach was validated through a comparative study with practical engineering cases and the Analytic Hierarchy Process, confirming its feasibility and practicality. It serves as a reference for later risk prevention in bridge. Liang 14 presented a multi-level evaluation system suitable for assessing the health status of prestressed continuous concrete bridges. This innovative rating system effectively supports bridge management and maintenance. Deng et al. 15 developed a comprehensive assessment method for the safety and reliability of existing railway bridges. The method serves as a theoretical basis for the maintenance and strengthening of the Songhua River Bridge on the Binbei Line. Ma et al. 16 proposed a systematic safety assessment for overwater bridge transportation, a technology that significantly increases the safety of bridges during sea transportation. Maljaars et al. 17 developed an evaluation method to determine the actual safety level of highway bridges and viaducts. This method focuses on assessing the impact of traffic behavior and consists of several levels. Zhu et al. 18 conducted an in-depth study on the safety assessment methods for Bridge Health Monitoring Systems (BHMS) using comprehensive fuzzy assessment techniques. They developed a novel Bridge Health Monitoring System based on safety assessment vectors. Li et al. 19 introduced a new security assessment method that combines Monte Carlo simulation (MCS) and Bayesian theory. This method enables reliable assessment and back-diagnosis of the overall safety performance of reinforced concrete bridges in cold regions. Fu et al. 20 used multi-source data from the construction and dismantling of a large-span reinforced concrete arch bridge in China. They applied the Analytic Hierarchy Process AHP to analyze the data from multiple sources and set a safety alarm threshold for the bridge during construction. Miyamoto et al. 21 proposed an early warning method for bridge safety using wireless sensor network technology. The method showed satisfactory results in various performance indicators such as flood delay, energy efficiency and throughput. Li et al. 22 established a risk assessment index system for safety in the operational phase of highway bridges. They then used cloud entropy weighting to objectively weigh various risk indicators and applied cloud model theory to risk assessment, emphasizing the objectivity of the assigned values. Feng et al. 23 presented an innovative approach that combines the Analytic Hierarchy Process (AHP) with the Finite Element Method (FEM). This approach highlighted the potential risk of influence of uncertain factors on the environment. Li et al. 24 proposed a probabilistic performance evaluation framework for a Suspension bridge, which considers factors such as wind speed, wind direction, bridge orientation, wind-wave correlation and parameter uncertainty. This framework provides a comprehensive and practical method for evaluating the performance and optimizing the design of SCBs under wind and wave loads. Xu et al. 25 presented a cloud-based Analytic Hierarchy Process (C-AHP) scoring system for determining inspection intervals. The proposed C-AHP rating system not only takes into account the vagueness of the AHP rating system, but also addresses its randomness and provides more stringent time intervals for routine inspections of long-span suspension bridges compared to the F-AHP rating system. Prasetyo et al. 26 used AHP and Promethee II methods to analyze and prioritize the ideal weight criteria for bridge handling. This approach makes the priority weighting process more dynamic and manageable.

In summary, there exists a paucity of research both domestically and internationally concerning the safety assessment of single tower suspension bridges featuring a steel box girder structure spanning over open sea expanses. In the field of safety assessment analysis for bridge structures, the traditional AHP is commonly used. In the traditional AHP framework, assessment matrices are created based on pairwise comparisons of selected criteria. However, the requirement for precise numerical values within these matrices requires respondents to have a thorough understanding of the relative importance of each choice. In practice, due to the complexity of objective phenomena and the human mind's use of fuzzy concepts, describing relative importance with precise numbers (such as 3, 1/9, etc.) becomes challenging. This leads to low credibility of weight calculation, cumbersome calculations, and weakened ability to comprehensively evaluate. Further refinements and improvements are required to determine the weights and improve the scoring matrix in a more meaningful way. Given this background, the present study improves the judgment matrix through a hybrid triangular fuzzy number logic structure with the aim of accounting for the uncertainty inherent in human analysis and cognition. This extension includes specifying the upper and lower limits of the possibility intervals as well as the most likely central values. By using the membership function of triangular fuzzy numbers, the study derives the possibilities of various parameters within the entire interval range. This method improves the determination of weights in the AHP, thereby improving its consistency and weight solution capabilities. By combining the improved AHP method with comprehensive fuzzy evaluation, the study proposes an improved AHP-fuzzy comprehensive evaluation approach to evaluate the safety status of a single-tower steel box girder suspension bridge over the sea. This approach increases the accuracy and rationality of the assessment results and aims to address the shortcomings in the safety assessment research of such bridge structures and provide valuable insights for the safety assessment of bridges.

Method for assessing the safety status of a single tower steel box girder suspension bridges over the sea

Basic principles of improved analytic hierarchy process.

The Analytic Hierarchy Process, introduced by American operations research professor Saaty in the 1970s 27 , is an effective method that converts semi-qualitative and semi-quantitative problems into quantitative calculations. AHP is known for its simplicity, rigorous mathematical foundation, and widespread application in analysis and decision making of complex systems. It serves as a practical, multi-criteria decision-making method and offers advantages such as systematicity, conciseness, flexibility and usefulness.

In traditional AHP, judgment matrices are determined through pairwise comparisons of selected criteria, which requires respondents to have a clear understanding of the relative importance of each selection. However, in practice, due to the large number of evaluation criteria in the AHP evaluation process, the complexity of objective phenomena and the application of fuzzy concepts in human thinking, experts find it difficult to give an accurate value when evaluating pairwise comparison indicators. Restricting the evaluation of importance levels to fixed and finite numbers ignores the fuzziness of experts' thought processes during evaluation, which leads to inconsistency problems in the evaluation matrices and to some extent limits the accuracy of the evaluations. To address this problem, this study integrates the triangular fuzzy number method, improves the weight determination method in the analytical hierarchy process, and improves its consistency and weight solution capabilities. Triangular fuzzy numbers represent a range concept that specifies the upper and lower limits of a probability interval as well as the maximum probability value. By using the membership function of triangular fuzzy numbers, the probabilities of various parameters within the entire interval range can be determined.

When constructing the judgment matrix \(A = \left( {a_{ij} } \right)_{n \times n}\) , we depart from the conventional method of using a single precise numerical value to represent the importance of two indicators, and instead employ the method of triangular fuzzy numbers to indicate the interrelationships between pairs of indicators. First, the most probable value “m” is determined, which represents the basic assessment of the relationship between the two indicators, followed by the establishment of the upper and lower limits, denoted “a” and “b”. The lower bound represents the minimum rating that experts consider possible, while the upper bound represents the maximum possible rating. Finally, an importance interval is provided, denoted as \(a_{ij} = \left[ {a_{ij} ,m_{ij} ,b_{ij} } \right]\) , where “ \(a\) ” represents the minimum importance value in the comparison of the two indicators, “ \(m\) ” denotes the most likely value in the comparison. and “ \(b\) ” denotes the maximum importance value in the comparison.

Using formula ( 1 ), transform the interval form of importance into specific precise numerical values-and obtain a consistent judgment matrix without the need for consistency checks.

Regarding formula ( 1 ), Professor Hua Luogeng has previously provided explanations for similar formulas: The probability of “ \(a_{ij}\) ” taking the minimum value, “ \(a\) ” and “ \(b\) ” taking the maximum value is relatively small, and the probability distribution closely follows the normal distribution distribution pattern. Therefore, assuming that “ \(a_{ij}\) ” takes the most likely value “ \(m\) ” is twice as likely as assuming that “ \(a\) ” takes the minimum value and “ \(b\) ” takes the maximum value. The weighted average algorithm produces the following results:

For example, if an expert's assessment of the relative weights of Indicator 1 and Indicator 2 is (2/3, 1, 3/2), then that expert's assessment of the weight of Indicator 1 relative to Indicator 2 is:

Improving the basic steps of the analytic hierarchy process

Clearly define the basic problems and relevant influencing factors

At the initial stage, it is important to have a comprehensive understanding of the problems being studied and the problems to be solved. The aim is to clearly identify the overarching problem, i.e. the end goal. After defining the basic problem, it is then a matter of identifying the relevant influencing factors that can play a role in solving the problem. These include both primary and secondary factors.

Establishing a hierarchical structure

Establishing a hierarchical structure is a crucial step in the AHP, especially when assessing the comprehensive safety status of bridges. The initial phase involves systematically categorizing the research problem and organizing it into hierarchical layers and thus constructing an evaluative indicator system or model. Within this system or model, the research problem is delineated into different indicator elements at different levels. These indicator elements are further classified based on their unique properties. In particular, each set of indicators at a lower level should be subordinate to the indicators at the level above. To improve the overall rationality of the hierarchical system or model, the division of hierarchical levels should conform to principles such as security, simplicity, independence and objectivity. The hierarchical structure can basically be divided into three levels:

Top level (target level): This level is also called the target level and contains only one indicator element. In the context of this document, the top level is the comprehensive safety assessment of the 2nd canal bridge.

Intermediate level (criterion level): This level is also called the criterion level and can contain several indicator elements. Each indicator at this level is constrained by and subordinate to the top level indicator. The indicators at this level should share common attributes. For example, in the case of a suspension bridge, the central indicators may include components such as main beams, main tower, main cables, hanging rods, etc.

Bottom level (alternative level): This level is also called alternative level and can also contain several indicator elements. These indicators represent various solution measures for achieving the goal. Each indicator at this level should have an influencing factor on the security status of the higher-level indicators. For example, within the “main beam” indicator at the middle level, the indicators at the lowest level could include the stress and displacement of the main beam. Stress and displacement can be further divided based on different locations and directions.

An ideal typical analytic hierarchy model is shown in Fig. 1 .

Ideal typical AHP model.

Construction of a triangular judgment matrix in fuzzy number form

Within the same hierarchy, different indicator elements are categorized into multiple levels based on their respective excellence or importance. Quantitative values are assigned to represent these levels. If the precision requirements are low, a 5-step quantitative method can be used, using the integers 1, 3, 5, 7 and 9 to express the importance of one indicator element over another. This is called the 5-stage quantitative method, where a higher number indicates greater importance of the former over the latter. To express the former as less important than the latter, the reciprocal of 1, 3, 5, 7 and 9 can be used. If higher precision in level division is required, interpolation can be applied within the 5 level method by introducing 2, 4, 6 and 8, creating a 9 level quantitative method. The meaning of the scale from 1 to 9 is shown in Table 1 .

Distribute evaluation matrix evaluation sheets to relevant experts and guide them to evaluate the scale table using the hierarchical analysis method described above. They are expected to perform pairwise comparisons of the indicators and then assign importance values. Summarize the assessments of each expert and create the evaluation matrix in the form of triangular fuzzy numbers, as shown in ( 2 ).

The approximation of the consistency of the matrix “A” leads to the generation of the consistency assessment matrix \(M = \left( {m_{ij} } \right)_{n \times n}\) , whereby the parameter \(m_{ij}\) is calculated as follows:

Based on the consistency judgment matrix, calculate the weights of each indicator

Start by calculating the nth root of the product of the elements in each row of the consistency judgment matrix.

where \(M_{i} \prod\nolimits_{j = 1}^{n} {m_{ij} }, \;\; \left( {i = 1,2, \ldots n} \right)\) .

Orthogonalize the above calculation results to obtain coefficients for each evaluation indicator.

\(W_{i} = \left( {W_{1} ,W_{2} , \ldots ,W_{n} } \right)^{T}\) therefore denotes the weight coefficients determined for the respective evaluation indicators.

Basic principle of the comprehensive fuzzy evaluation method

In 1965, Professor L.A. Zadeh from the United States published an article on fuzzy logic in an international journal in which he established the concept of fuzzy set theory and marked the birth of fuzzy mathematics 28 . Fuzzy or uncertain entities can be described using fuzzy mathematics. The term “fuzzy” refers to the variability between objective units that arises from the uncertainty in classifying units due to subjective differences. It is a form of description for concepts that are clearly defined but have unclear boundaries. In practical life, many concepts are vague, such as: youth, early morning, cold, etc. Due to subjective and objective limitations, each individual has different mental limits for these phenomena, which reflect people's subjective factors. When the fundamental concepts are unclear, accurate identification of an object is unrealistic. Instead, one can only assess the extent to which the object is likely to correspond to the concept.

Fuzzy sets and membership functions

In classical set theory, for a given element “ \({\text{x}}\) ”, its membership in the classical set “ \({\text{A}}\) ” is clear. The relationship between the two is binary, either belonging or not belonging, a clear distinction represented by either \({\text{x}} \in A\) or \({\text{x}} \notin A\) . This relationship can be described using a characteristic function. However, for certain indefinite quantities or units, their values cannot be determined precisely. Therefore, it becomes necessary to apply fuzzy set theory to handle such cases.

In fuzzy set theory, the transformation of the characteristic function into a membership function is used to solve problems. Membership degrees are used to reflect the degree of membership of a fuzzy set to a fuzzy set. Assuming a discourse universe “ \({\text{U}}\) ” and a set “ \({\text{A}}\) ”, for each element \({\text{x}} \in A\) , a function \(\mu_{A} \left( {\text{x}} \right) \in \left[ {01} \right]\) can be used to represent the degree to which element “ \({\text{x}}\) ” belongs to the set “ \({\text{A}}\) ”, as follows:

In the context of fuzzy set theory, the range “ \({\text{U}}\) ” is called the set of elements, while the set “ \({\text{A}}\) ” is called a fuzzy set. The function \(\mu_{A} \left( {\text{x}} \right)\) , called the membership function, serves as the membership function for “A”. In this scenario, a fuzzy set can be fully represented by a corresponding fuzzy function. The membership function \(\mu_{A} \left( {\text{x}} \right)\) assigns values ranging from 0 to 1, where the value is to 1, the higher the degree of membership of the element “ \({\text{x}}\) ” to a fuzzy set in the fuzzy set” \({\text{A}}\) ”; the closer it is to 0, the lower the degree of membership of the element “ \({\text{x}}\) ” to a fuzzy quantity in the fuzzy set ” \({\text{A}}\) ”.

Methods for determining membership functions

Fuzzy set and membership function are inextricably linked. The fuzzy set is represented by the membership function. The membership function is also the implementation of fuzzy set operations. Using the correct membership function is the basis for applying fuzzy set theory to solve practical problems. This article uses fuzzy statistics to determine the membership function.

Fuzzy statistics are used to represent the membership function in a similar way to probability statistics to determine the degree of membership. The basic steps are as follows: First, a fuzzy set “A” and a discourse area “U” are determined. Then, based on their personal experience, several experts or scientists judge which fuzzy set or which fuzzy evaluation interval of a specific element “ \({\text{x}}_{0}\) ” in the discourse area ”U” belongs to the fuzzy set “A” The expression of the membership function can be expressed as follows:

where “n” is the number of experts or scientists. In this way, the membership level is determined by the statistical membership frequency. When “n” experts are invited to an experiment, the membership frequency “ \(\mu\) ” tends to the stable value as the “n” value increases, and the stable frequency value is the membership degree of the element “ \({\text{x}}_{0}\) ” belonging to the fuzzy set “A”.

Basic steps of first-level comprehensive fuzzy evaluation

Identification of the factor set

When conducting fuzzy assessments, the first step is to identify the various factors that affect the target's assessment results. For example, in a comprehensive safety assessment of a suspension bridge, the influencing factors include the main girder, main tower, main cables, hanging rods and others. The totality of these individual factors is called a factor set and is usually denoted by the symbol “U”. This can be expressed as follows:

Determine the factor weight vector

In the determined factor set \({\text{U}} = \left\{ {\mu_{{1}} ,\mu_{{2}} , \ldots ,\mu_{{\text{n}}} } \right\}\) , each factor has a different influence on the evaluation goal. Therefore, it is necessary to meaningfully divide the weight of each factor and assign a corresponding weight value, which can be determined through an analytical hierarchy process. The weight value of each factor can be converted into a weight vector, generally expressed by “A”:

In the formula, \(a_{1} ,a_{2} , \ldots a_{n}\) represents the weight value corresponding to the factor \(u_{1} ,u_{2} , \ldots u_{n}\) , and \(0 \le a_{i} \le 1\) .

Determine the amount of fuzzy comments

After determining the factor set \({\text{U}} = \left\{ {\mu_{{1}} ,\mu_{{2}} , \ldots ,\mu_{{\text{n}}} } \right\}\) , a corresponding fuzzy comment set needs to be created so that the evaluator can achieve specific judgment results for each element in the factor set. For example, according to the classification of the technical condition of a bridge, the bridge can be divided into categories 1, 2, 3, 4 and 5, and the corresponding fuzzy comments on the bridge status include intact, good, fairly good, poor and dangerous. The set of fuzzy evaluation is called fuzzy evaluation theorem and is generally used in the “V” representation, that is:

In the equation, \({\text{v}}_{1} ,{\text{v}}_{2} , \ldots ,{\text{v}}_{m}\) represents “m” fuzzy evaluations created for each factor.

Single factor evaluation

The single factor evaluation refers to the individual evaluation of each factor within the factor set “U”. This process determines the degree of membership of each factor to different ratings in the fuzzy rating set “V”. For example, when evaluating the “i”-th factor \(\mu_{{\text{i}}}\) within the factor set “U”, the degree of membership of this factor to the “j”-th evaluation “V” in the fuzzy evaluation set \({\text{v}}_{{\text{j}}}\) can be specified as \({\text{r}}_{{{\text{ij}}}}\) . The membership degrees obtained for the \({\text{i}}\) th factor \(\mu_{{\text{i}}}\) can be represented as \(r_{j}\) , which in the context of bridge building can be expressed as follows:

In the equation, \({\text{r}}_{{{\text{i1}}}} ,{\text{r}}_{{{\text{i2}}}} , \ldots ,{\text{r}}_{{{\text{im}}}}\) represents the membership degrees of the \({\text{i}}\) th factor to \({\text{m}}\) fuzzy evaluations, where \(0 \le {\text{r}}_{{{\text{im}}}} \le 1\) .

Building a comprehensive fuzzy evaluation matrix

When evaluating a goal with multiple influencing factors, the aggregation of the membership degree sets resulting from the evaluation of all factors within the factor set \({\text{U}}\) leads to the creation of a comprehensive assessment matrix for the evaluation goal. This matrix is usually represented by the symbol \({\text{R}}\) . It can be expressed as:

Fuzzy comprehensive evaluation

After determining the weight vector \(A_{1 \times n}\) for each factor and constructing the comprehensive judgment matrix \(R_{{{\text{n}} \times {\text{m}}}}\) , fuzzy transformation is applied to both using fuzzy operators. This process produces a fuzzy valuation vector \({\text{B}} = \left( {{\text{b}}_{{1}} ,{\text{b}}_{{2}} , \ldots ,{\text{b}}_{{\text{m}}} } \right)\) , the calculation formula of which is expressed as follows:

In the equation, " \(\circ\) " represents the fuzzy operator.

Fuzzy operator

In the process of fuzzy transformation, fuzzy operators generally include primary factor determination type, primary factor prominence type, unbalanced average type and weighted average type, among others. The weighted average operator is characterized by clear weighting effects and high completeness. Therefore, this article uses the weighted average type operator for calculation. The specific calculation is as follows:

Handling evaluation results

After the calculation process of comprehensive fuzzy evaluation, the final evaluation result “B” is obtained. At this stage it is necessary to process the assessment indicators. This article uses the maximum membership degree principle to process the fuzzy, comprehensive evaluation results and derive explicit evaluation results. The specific calculation method for the maximum membership degree principle is as follows:

Then the comprehensive assessment results of \({\text{i}}_{0}\) levels are determined. This operating method is relatively straightforward, with the majority of comprehensive evaluation approaches typically employing the maximum membership degree principle.

Multi-level fuzzy comprehensive evaluation

Typically, when evaluating a complex system, it's necessary to consider the influences of various factors, which may also include sub-factors. Therefore, a comprehensive assessment of membership degrees across different factor levels is needed. In such cases, a multi-level assessment must be conducted in conjunction with the situation of each factor layer. When there are numerous influencing factors affecting the evaluation object, it is difficult to meaningfully assign the weights, which means that it is difficult to determine the hierarchy of individual factors within the overall assessment. In such situations, a multi-level fuzzy comprehensive assessment method is needed for determination.

For example, when assessing the condition of a bridge, a bridge is divided into superstructure, substructure, auxiliary structure and bridge deck system according to its structure. Each structure is first subjected to a comprehensive assessment, and the assessment results then serve as single-factor assessments at a higher level. The weights of these four structures are denoted by A, and a comprehensive second-level fuzzy evaluation is performed. The calculation process is as follows.

In the above equation, “C” represents the comprehensive evaluation result of the bridge condition. In cases with multiple influencing factors, it's advisable to first stratify and classify the factors, and then proceed with multi-level fuzzy comprehensive evaluation.

Improved AHP-fuzzy comprehensive evaluation model for single tower steel box girder suspension bridges over the sea

The safety evaluation of single-tower steel box girder bridges over the sea includes various factors, including the steel box girder, concrete main tower, main cables, suspension rods and others, making it a typical multi-dimensional evaluation challenge. In the improved AHP method, although there are weights for each indicator, there is still a subjective element in the expert evaluation process. Therefore, it is crucial to further improve the quality of quantitative assessment through comprehensive fuzzy assessment methods. The evaluation model for single-tower steel box girder oversea suspension bridges based on the improved AHP-Fuzzy Comprehensive Evaluation is shown in Fig. 2 .

Health monitoring of a cross-sea single tower steel box girder suspension bridge

The condition monitoring of steel box girder suspension bridges with a tower over the sea primarily requires the installation of various types of sensors on site. These sensors collect monitoring data that reflects the structural safety status. By analyzing and processing this monitoring data, the health status of the structure is determined. This process creates a solid foundation for conducting bridge safety assessments and provides reference and decision support for bridge maintenance and management.

Overview of the bridge health monitoring system

The condition monitoring system for the steel box girder tower suspension bridge over the sea consists of five main subsystems: the sensor subsystem, the data acquisition and transmission subsystem, the data storage and management subsystem, the data processing and analysis subsystem and the structure monitoring. Early warning and security assessment subsystem. These subsystems are integrated using system integration technologies to coordinate the operation of hardware and software components. The configuration of the bridge condition monitoring system is shown in Fig. 3 .

Validation of engineering cases

Project overview.

Bridge No. 2 is an important part of a northern coastal bridge and serves as an important sea connection between the eastern and western parts of the Bay City. It plays an important role in the Qinglan Expressway network. Bridge No. 2 is designed as a continuous, self-anchored steel box girder suspension bridge with a tower and a main span of 260 m. It is equipped with two main cables and 58 hanging rods. The span is 80 + 190 + 260 + 80 m with a total length of 610 m. The main and side panels utilize a suspension design with a continuous, semi-floating four panel system, as shown in Fig. 5 . The tower of Bridge No. 2 consists of a single-column concrete tower and the main girder is made of segmented steel box girder construction. Both the main and side spans are configured as suspension systems, with a main span aspect ratio of 1/12.53 and a side span aspect ratio of 1/18.04.

General structure of the bridge.

Application of the improved AHP in Bridge No. 2

Structure of the evaluation index system.

Based on the structural form, characteristics and monitored content of Bridge No. 2, the AHP was used to hierarchize the structural system of Bridge No. 2. This led to the creation of a rating index system with corresponding hierarchical divisions. The highest level, the target level, refers to the comprehensive assessment of the safety status of Bridge No. 2. The middle level consists of primary indicators, a total of 8, and the lowest level includes secondary indicators, a total of 29. The hierarchical assessment The system for Bridge No. 2 is listed in Table 4 .

In order to obtain the evaluation matrix for each indicator level of the suspension bridge, a survey questionnaire is developed, which is based on the created evaluation indicator system for Bridge No.2 and involves the 9-stage quantitative method for establishing evaluation criteria for each indicator, determining the hierarchical relationships and weight comparisons between the Indicators. Surveys on the No.2 Bridge Evaluation Indicator System were distributed to experts or scientists familiar with suspension bridge designs, and then promptly collected and analyzed.

Construction of an assessment matrix in the form of triangular fuzzy numbers for primary indicators and weight calculation

Based on the ratings assigned from the expert survey questionnaires, coupled with the finite element model analysis of Bridge No. 2, various monitoring values from the health monitoring system and with reference to the “Technical Condition Assessment Standards for Highway Bridges” (JTG/TH21-2011) a comprehensive calculation results in the assessment matrix shown in Table 5 .

The assessment matrix is subjected to a consistency approximation in order to obtain a consistency judgment matrix:

Calculate the nth root of the product of the elements in each row of the consistency judgment matrix:

The above calculation results are orthogonalized to obtain the weight coefficient of each evaluation index: \(W_{i} = \frac{{\overline{{W_{i} }} }}{{\sum\nolimits_{j = 1}^{n} {w_{j} } }}\)

Through the above calculation, the weights of the first level index steel box beam, concrete main tower, main cable system, suspension system, anchor bar, substructure, auxiliary facilities and environmental factors can be found as follows: 0.0978, 0.0978, 0, 3121, 0.2067, 0.2067, 0.0581, 0.0104, 0.0104, which shows that the weight value of the main cable is the largest and the weight value of the auxiliary facilities and environmental factors is the smallest.

Calculation of secondary indicator weights

Calculation of the secondary indicator weights for the primary evaluation criteria of the first-level box girder

The method of constructing the judgment matrix in the triangular fuzzy number form for same-level indicators is consistent, and the comprehensive results are presented in the following matrix, as shown in Table 6 .

According to Table 7 , it can be observed that the weight value for the vibration frequency of the box girder is the highest, whereas the weight values for main girder stress and main girder longitudinal displacement are the lowest.

Calculation of secondary criterion weights corresponding to the primary evaluation criteria for a concrete main tower

Similarly, the weight values for the primary evaluation criteria corresponding to main tower stress, main tower longitudinal displacement, and main tower lateral displacement can be obtained, as shown in Table 9 .

From Table 9 , it can be inferred that the weight assigned to the longitudinal displacement of the main tower is the highest, while the weight for the stress on the main tower is the lowest.

Calculation of secondary criterion weights corresponding to primary evaluation criteria for primary cable system

Similarly, the weight values for the primary evaluation criteria can be determined according to the main cable force, main cable protection layer, clamping force and saddle displacement, as shown in Table 11 .

From Table 11 , it can be observed that the weight value for the main cable force is the highest, while the weight value for the clamp force is the smallest.

Calculation of secondary indicator weights corresponding to primary suspension rod system evaluation criteria

Similarly, the weights for the evaluation criteria of the primary suspension rod system can be calculated according to the suspension rod tension, the suspension rod protective layer and the damper, as shown in Table 13 .

From Table 13 , it can be seen that the weight value for the tension of the suspender cable is the highest, while the weight value for the protective layer of the suspender cable is the lowest.

Calculation of weights for secondary indicators that correspond to the primary anchoring evaluation criteria.

Similarly, the weight values for the displacement of the primary anchoring system and the concrete strength evaluation criteria can be calculated as shown in Table 15 .

From Table 15 , it can be concluded that the weight value for anchor displacement is the highest, while the weight value for concrete strength is the lowest.

Calculation of weight for secondary indicators corresponding to the primary evaluation criteria for the substructure.

The method of constructing the judgment matrix in the triangular fuzzy number form for indicators at the same level is consistent, and the comprehensive results are presented in the following matrix, as shown in Table 16 .

Similarly, the weight values for the primary substructure assessment criteria corresponding to support displacement, foundation settlement, and concrete strength can be calculated, as shown in Table 17 .

From Table 17 , it can be seen that the weighting value for foundation settlement is the largest, while the weighting value for concrete strength is the smallest.

Calculation of weighting values for secondary indicators that correspond to the primary assessment criteria for ancillary facilities.

Similarly, weight values can be calculated for the primary assessment criteria for ancillary facilities relating to bridge decking, expansion joints, drainage systems, lighting systems and railings, as shown in Table 19 .

From Table 19 , it can be seen that the weight values for bridge deck and expansion joints are the highest, while the weight value for railings is the lowest.

Calculation of weight values for secondary indicators that correspond to the assessment criteria for primary environmental factors.

Similarly, the weight values for wind speed, temperature and humidity can be determined, which correspond to the primary evaluation criteria for environmental factors. As shown in Table 21 :

From Table 21 , it can be concluded that the weight value for CL ions is the highest, while the weight value for temperature is the lowest.

Safety assessment of Canal Bridge No. 2 based on an improved comprehensive AHP + Fuzzy assessment

In accordance with the improved AHP applied to the evaluation criteria system for the components of Bridge No. 2, it is divided into three levels: the highest level (objective level), the intermediate level (first-level indicators), and the lowest level (second-level indicators). In this paper, the eight first-level indicators at the intermediate level are designated as the first layer of the factor set, denoted as \(U_{1}\) , and the 28 s-level indicators at the lowest level are designated as the second layer of the factor set, denoted as \(U_{2}\) , The weight values of each level's factors are determined based on the calculations presented in " Bridge health monitoring project and sensor placement " section of this paper.

Fuzzy statistical method is employed in this study to determine the membership functions. A survey questionnaire is distributed to relevant experts or scholars to individually evaluate and score all the factors in the third layer of factors set \(U_{2}\) . The recipients of the survey questionnaire include the users of Bridge No. 2, maintenance managers, and individuals involved in the bridge load testing. Fuzzy evaluations in this paper are primarily based on relevant specifications, combined with finite element simulation responses, actual data from health monitoring systems, and the real condition of the bridge. The fuzzy evaluations are classified into five levels: "Intact," "Good," "Fairly Good," "Poor," and "Dangerous," denoted as V1 = Intact, V2 = Good, V3 = Fairly Good, V4 = Poor, V5 = Dangerous. The set of fuzzy evaluations is represented as V = {Intact, Good, Fairly Good, Poor, Dangerous}.

Statistical analysis was performed on the distributed and collected expert questionnaires to determine the membership frequencies or membership degrees for each factor indicator. The statistical results are shown in Table 22 .

The safety status assessment of Bridge No. 2 relied on the improved AHP-fuzzy comprehensive evaluation method proposed in this study and showed favorable results. The introduced improved AHP-Fuzzy comprehensive evaluation method for bridge safety evaluation has certain significance for technical guidance.

Conclusions

Using the triangular fuzzy number method, improvements have been made to the judgment matrix, allowing experts to rate the importance of indicators without being confined to providing an exact numerical value; instead, they need only provide a score range. This reduces the influence of subjective factors on the evaluation results, ensures the consistency of the judgment matrix, and improves the performance of determining the AHP indicator weight.

By combining the improved AHP with a comprehensive fuzzy assessment, a model is constructed to evaluate the safety status of a single-tower steel box girder suspension bridge over the sea. Building on the determination of the weights of various evaluation indicators using the improved AHP, the comprehensive fuzzy evaluation method is applied to calculate the membership degrees of each indicator, thereby evaluating the safety status of the bridge, resulting in a more reasonable and reliable evaluation result.

The assessment of the safety status of the No. 2 Channel Bridge shows that the bridge is currently in good condition overall and should undergo routine maintenance in the future. It was found that the main cable system of the suspension bridge has the highest weight values, while the weightage of auxiliary facilities and environmental factors is the lowest. Among the environmental factors, chloride ions (CL) were assigned the highest weightage, which can corrode the concrete structure of the bridge, requiring increased additional anti-corrosion measures.

The assessment of the safety status of the No. 2 Channel Bridge shows that the proposed method is effective in assessing bridges under the condition that data from health monitoring systems are collected, so as to determine the safety status of the bridge. This method also accurately evaluates the index system and is of considerable importance for engineering guidance.

Bibliography

This glossary is intended to assist you in understanding commonly used terms and concepts when reading, interpreting, and evaluating scholarly research. Also included are common words and phrases defined within the context of how they apply to research in the social and behavioral sciences.

Acculturation -- refers to the process of adapting to another culture, particularly in reference to blending in with the majority population [e.g., an immigrant adopting American customs]. However, acculturation also implies that both cultures add something to one another, but still remain distinct groups unto themselves.
Accuracy -- a term used in survey research to refer to the match between the target population and the sample.
Affective Measures -- procedures or devices used to obtain quantified descriptions of an individual's feelings, emotional states, or dispositions.
Aggregate -- a total created from smaller units. For instance, the population of a county is an aggregate of the populations of the cities, rural areas, etc. that comprise the county. As a verb, it refers to total data from smaller units into a large unit.
Anonymity -- a research condition in which no one, including the researcher, knows the identities of research participants.
Baseline -- a control measurement carried out before an experimental treatment.
Behaviorism -- school of psychological thought concerned with the observable, tangible, objective facts of behavior, rather than with subjective phenomena such as thoughts, emotions, or impulses. Contemporary behaviorism also emphasizes the study of mental states such as feelings and fantasies to the extent that they can be directly observed and measured.
Beliefs -- ideas, doctrines, tenets, etc. that are accepted as true on grounds which are not immediately susceptible to rigorous proof.
Benchmarking -- systematically measuring and comparing the operations and outcomes of organizations, systems, processes, etc., against agreed upon "best-in-class" frames of reference.
Bias -- a loss of balance and accuracy in the use of research methods. It can appear in research via the sampling frame, random sampling, or non-response. It can also occur at other stages in research, such as while interviewing, in the design of questions, or in the way data are analyzed and presented. Bias means that the research findings will not be representative of, or generalizable to, a wider population.
Case Study -- the collection and presentation of detailed information about a particular participant or small group, frequently including data derived from the subjects themselves.
Causal Hypothesis -- a statement hypothesizing that the independent variable affects the dependent variable in some way.
Causal Relationship -- the relationship established that shows that an independent variable, and nothing else, causes a change in a dependent variable. It also establishes how much of a change is shown in the dependent variable.
Causality -- the relation between cause and effect.
Central Tendency -- any way of describing or characterizing typical, average, or common values in some distribution.
Chi-square Analysis -- a common non-parametric statistical test which compares an expected proportion or ratio to an actual proportion or ratio.
Claim -- a statement, similar to a hypothesis, which is made in response to the research question and that is affirmed with evidence based on research.
Classification -- ordering of related phenomena into categories, groups, or systems according to characteristics or attributes.
Cluster Analysis -- a method of statistical analysis where data that share a common trait are grouped together. The data is collected in a way that allows the data collector to group data according to certain characteristics.
Cohort Analysis -- group by group analytic treatment of individuals having a statistical factor in common to each group. Group members share a particular characteristic [e.g., born in a given year] or a common experience [e.g., entering a college at a given time].
Confidentiality -- a research condition in which no one except the researcher(s) knows the identities of the participants in a study. It refers to the treatment of information that a participant has disclosed to the researcher in a relationship of trust and with the expectation that it will not be revealed to others in ways that violate the original consent agreement, unless permission is granted by the participant.
Confirmability Objectivity -- the findings of the study could be confirmed by another person conducting the same study.
Construct -- refers to any of the following: something that exists theoretically but is not directly observable; a concept developed [constructed] for describing relations among phenomena or for other research purposes; or, a theoretical definition in which concepts are defined in terms of other concepts. For example, intelligence cannot be directly observed or measured; it is a construct.
Construct Validity -- seeks an agreement between a theoretical concept and a specific measuring device, such as observation.
Constructivism -- the idea that reality is socially constructed. It is the view that reality cannot be understood outside of the way humans interact and that the idea that knowledge is constructed, not discovered. Constructivists believe that learning is more active and self-directed than either behaviorism or cognitive theory would postulate.
Content Analysis -- the systematic, objective, and quantitative description of the manifest or latent content of print or nonprint communications.
Context Sensitivity -- awareness by a qualitative researcher of factors such as values and beliefs that influence cultural behaviors.
Control Group -- the group in an experimental design that receives either no treatment or a different treatment from the experimental group. This group can thus be compared to the experimental group.
Controlled Experiment -- an experimental design with two or more randomly selected groups [an experimental group and control group] in which the researcher controls or introduces the independent variable and measures the dependent variable at least two times [pre- and post-test measurements].
Correlation -- a common statistical analysis, usually abbreviated as r, that measures the degree of relationship between pairs of interval variables in a sample. The range of correlation is from -1.00 to zero to +1.00. Also, a non-cause and effect relationship between two variables.
Covariate -- a product of the correlation of two related variables times their standard deviations. Used in true experiments to measure the difference of treatment between them.
Credibility -- a researcher's ability to demonstrate that the object of a study is accurately identified and described based on the way in which the study was conducted.
Critical Theory -- an evaluative approach to social science research, associated with Germany's neo-Marxist “Frankfurt School,” that aims to criticize as well as analyze society, opposing the political orthodoxy of modern communism. Its goal is to promote human emancipatory forces and to expose ideas and systems that impede them.
Data -- factual information [as measurements or statistics] used as a basis for reasoning, discussion, or calculation.
Data Mining -- the process of analyzing data from different perspectives and summarizing it into useful information, often to discover patterns and/or systematic relationships among variables.
Data Quality -- this is the degree to which the collected data [results of measurement or observation] meet the standards of quality to be considered valid [trustworthy] and reliable [dependable].
Deductive -- a form of reasoning in which conclusions are formulated about particulars from general or universal premises.
Dependability -- being able to account for changes in the design of the study and the changing conditions surrounding what was studied.
Dependent Variable -- a variable that varies due, at least in part, to the impact of the independent variable. In other words, its value “depends” on the value of the independent variable. For example, in the variables “gender” and “academic major,” academic major is the dependent variable, meaning that your major cannot determine whether you are male or female, but your gender might indirectly lead you to favor one major over another.
Deviation -- the distance between the mean and a particular data point in a given distribution.
Discourse Community -- a community of scholars and researchers in a given field who respond to and communicate to each other through published articles in the community's journals and presentations at conventions. All members of the discourse community adhere to certain conventions for the presentation of their theories and research.
Discrete Variable -- a variable that is measured solely in whole units, such as, gender and number of siblings.
Distribution -- the range of values of a particular variable.
Effect Size -- the amount of change in a dependent variable that can be attributed to manipulations of the independent variable. A large effect size exists when the value of the dependent variable is strongly influenced by the independent variable. It is the mean difference on a variable between experimental and control groups divided by the standard deviation on that variable of the pooled groups or of the control group alone.
Emancipatory Research -- research is conducted on and with people from marginalized groups or communities. It is led by a researcher or research team who is either an indigenous or external insider; is interpreted within intellectual frameworks of that group; and, is conducted largely for the purpose of empowering members of that community and improving services for them. It also engages members of the community as co-constructors or validators of knowledge.
Empirical Research -- the process of developing systematized knowledge gained from observations that are formulated to support insights and generalizations about the phenomena being researched.
Epistemology -- concerns knowledge construction; asks what constitutes knowledge and how knowledge is validated.
Ethnography -- method to study groups and/or cultures over a period of time. The goal of this type of research is to comprehend the particular group/culture through immersion into the culture or group. Research is completed through various methods but, since the researcher is immersed within the group for an extended period of time, more detailed information is usually collected during the research.
Expectancy Effect -- any unconscious or conscious cues that convey to the participant in a study how the researcher wants them to respond. Expecting someone to behave in a particular way has been shown to promote the expected behavior. Expectancy effects can be minimized by using standardized interactions with subjects, automated data-gathering methods, and double blind protocols.
External Validity -- the extent to which the results of a study are generalizable or transferable.
Factor Analysis -- a statistical test that explores relationships among data. The test explores which variables in a data set are most related to each other. In a carefully constructed survey, for example, factor analysis can yield information on patterns of responses, not simply data on a single response. Larger tendencies may then be interpreted, indicating behavior trends rather than simply responses to specific questions.
Field Studies -- academic or other investigative studies undertaken in a natural setting, rather than in laboratories, classrooms, or other structured environments.
Focus Groups -- small, roundtable discussion groups charged with examining specific topics or problems, including possible options or solutions. Focus groups usually consist of 4-12 participants, guided by moderators to keep the discussion flowing and to collect and report the results.
Framework -- the structure and support that may be used as both the launching point and the on-going guidelines for investigating a research problem.
Generalizability -- the extent to which research findings and conclusions conducted on a specific study to groups or situations can be applied to the population at large.
Grey Literature -- research produced by organizations outside of commercial and academic publishing that publish materials, such as, working papers, research reports, and briefing papers.
Grounded Theory -- practice of developing other theories that emerge from observing a group. Theories are grounded in the group's observable experiences, but researchers add their own insight into why those experiences exist.
Group Behavior -- behaviors of a group as a whole, as well as the behavior of an individual as influenced by his or her membership in a group.
Hypothesis -- a tentative explanation based on theory to predict a causal relationship between variables.
Independent Variable -- the conditions of an experiment that are systematically manipulated by the researcher. A variable that is not impacted by the dependent variable, and that itself impacts the dependent variable. In the earlier example of "gender" and "academic major," (see Dependent Variable) gender is the independent variable.
Individualism -- a theory or policy having primary regard for the liberty, rights, or independent actions of individuals.
Inductive -- a form of reasoning in which a generalized conclusion is formulated from particular instances.
Inductive Analysis -- a form of analysis based on inductive reasoning; a researcher using inductive analysis starts with answers, but formulates questions throughout the research process.
Insiderness -- a concept in qualitative research that refers to the degree to which a researcher has access to and an understanding of persons, places, or things within a group or community based on being a member of that group or community.
Internal Consistency -- the extent to which all questions or items assess the same characteristic, skill, or quality.
Internal Validity -- the rigor with which the study was conducted [e.g., the study's design, the care taken to conduct measurements, and decisions concerning what was and was not measured]. It is also the extent to which the designers of a study have taken into account alternative explanations for any causal relationships they explore. In studies that do not explore causal relationships, only the first of these definitions should be considered when assessing internal validity.
Life History -- a record of an event/events in a respondent's life told [written down, but increasingly audio or video recorded] by the respondent from his/her own perspective in his/her own words. A life history is different from a "research story" in that it covers a longer time span, perhaps a complete life, or a significant period in a life.
Margin of Error -- the permittable or acceptable deviation from the target or a specific value. The allowance for slight error or miscalculation or changing circumstances in a study.
Measurement -- process of obtaining a numerical description of the extent to which persons, organizations, or things possess specified characteristics.
Meta-Analysis -- an analysis combining the results of several studies that address a set of related hypotheses.
Methodology -- a theory or analysis of how research does and should proceed.
Methods -- systematic approaches to the conduct of an operation or process. It includes steps of procedure, application of techniques, systems of reasoning or analysis, and the modes of inquiry employed by a discipline.
Mixed-Methods -- a research approach that uses two or more methods from both the quantitative and qualitative research categories. It is also referred to as blended methods, combined methods, or methodological triangulation.
Modeling -- the creation of a physical or computer analogy to understand a particular phenomenon. Modeling helps in estimating the relative magnitude of various factors involved in a phenomenon. A successful model can be shown to account for unexpected behavior that has been observed, to predict certain behaviors, which can then be tested experimentally, and to demonstrate that a given theory cannot account for certain phenomenon.
Models -- representations of objects, principles, processes, or ideas often used for imitation or emulation.
Naturalistic Observation -- observation of behaviors and events in natural settings without experimental manipulation or other forms of interference.
Norm -- the norm in statistics is the average or usual performance. For example, students usually complete their high school graduation requirements when they are 18 years old. Even though some students graduate when they are younger or older, the norm is that any given student will graduate when he or she is 18 years old.
Null Hypothesis -- the proposition, to be tested statistically, that the experimental intervention has "no effect," meaning that the treatment and control groups will not differ as a result of the intervention. Investigators usually hope that the data will demonstrate some effect from the intervention, thus allowing the investigator to reject the null hypothesis.
Ontology -- a discipline of philosophy that explores the science of what is, the kinds and structures of objects, properties, events, processes, and relations in every area of reality.
Panel Study -- a longitudinal study in which a group of individuals is interviewed at intervals over a period of time.
Participant -- individuals whose physiological and/or behavioral characteristics and responses are the object of study in a research project.
Peer-Review -- the process in which the author of a book, article, or other type of publication submits his or her work to experts in the field for critical evaluation, usually prior to publication. This is standard procedure in publishing scholarly research.
Phenomenology -- a qualitative research approach concerned with understanding certain group behaviors from that group's point of view.
Philosophy -- critical examination of the grounds for fundamental beliefs and analysis of the basic concepts, doctrines, or practices that express such beliefs.
Phonology -- the study of the ways in which speech sounds form systems and patterns in language.
Policy -- governing principles that serve as guidelines or rules for decision making and action in a given area.
Policy Analysis -- systematic study of the nature, rationale, cost, impact, effectiveness, implications, etc., of existing or alternative policies, using the theories and methodologies of relevant social science disciplines.
Population -- the target group under investigation. The population is the entire set under consideration. Samples are drawn from populations.
Position Papers -- statements of official or organizational viewpoints, often recommending a particular course of action or response to a situation.
Positivism -- a doctrine in the philosophy of science, positivism argues that science can only deal with observable entities known directly to experience. The positivist aims to construct general laws, or theories, which express relationships between phenomena. Observation and experiment is used to show whether the phenomena fit the theory.
Predictive Measurement -- use of tests, inventories, or other measures to determine or estimate future events, conditions, outcomes, or trends.
Principal Investigator -- the scientist or scholar with primary responsibility for the design and conduct of a research project.
Probability -- the chance that a phenomenon will occur randomly. As a statistical measure, it is shown as p [the "p" factor].
Questionnaire -- structured sets of questions on specified subjects that are used to gather information, attitudes, or opinions.
Random Sampling -- a process used in research to draw a sample of a population strictly by chance, yielding no discernible pattern beyond chance. Random sampling can be accomplished by first numbering the population, then selecting the sample according to a table of random numbers or using a random-number computer generator. The sample is said to be random because there is no regular or discernible pattern or order. Random sample selection is used under the assumption that sufficiently large samples assigned randomly will exhibit a distribution comparable to that of the population from which the sample is drawn. The random assignment of participants increases the probability that differences observed between participant groups are the result of the experimental intervention.
Reliability -- the degree to which a measure yields consistent results. If the measuring instrument [e.g., survey] is reliable, then administering it to similar groups would yield similar results. Reliability is a prerequisite for validity. An unreliable indicator cannot produce trustworthy results.
Representative Sample -- sample in which the participants closely match the characteristics of the population, and thus, all segments of the population are represented in the sample. A representative sample allows results to be generalized from the sample to the population.
Rigor -- degree to which research methods are scrupulously and meticulously carried out in order to recognize important influences occurring in an experimental study.
Sample -- the population researched in a particular study. Usually, attempts are made to select a "sample population" that is considered representative of groups of people to whom results will be generalized or transferred. In studies that use inferential statistics to analyze results or which are designed to be generalizable, sample size is critical, generally the larger the number in the sample, the higher the likelihood of a representative distribution of the population.
Sampling Error -- the degree to which the results from the sample deviate from those that would be obtained from the entire population, because of random error in the selection of respondent and the corresponding reduction in reliability.
Saturation -- a situation in which data analysis begins to reveal repetition and redundancy and when new data tend to confirm existing findings rather than expand upon them.
Semantics -- the relationship between symbols and meaning in a linguistic system. Also, the cuing system that connects what is written in the text to what is stored in the reader's prior knowledge.
Social Theories -- theories about the structure, organization, and functioning of human societies.
Sociolinguistics -- the study of language in society and, more specifically, the study of language varieties, their functions, and their speakers.
Standard Deviation -- a measure of variation that indicates the typical distance between the scores of a distribution and the mean; it is determined by taking the square root of the average of the squared deviations in a given distribution. It can be used to indicate the proportion of data within certain ranges of scale values when the distribution conforms closely to the normal curve.
Statistical Analysis -- application of statistical processes and theory to the compilation, presentation, discussion, and interpretation of numerical data.
Statistical Bias -- characteristics of an experimental or sampling design, or the mathematical treatment of data, that systematically affects the results of a study so as to produce incorrect, unjustified, or inappropriate inferences or conclusions.
Statistical Significance -- the probability that the difference between the outcomes of the control and experimental group are great enough that it is unlikely due solely to chance. The probability that the null hypothesis can be rejected at a predetermined significance level [0.05 or 0.01].
Statistical Tests -- researchers use statistical tests to make quantitative decisions about whether a study's data indicate a significant effect from the intervention and allow the researcher to reject the null hypothesis. That is, statistical tests show whether the differences between the outcomes of the control and experimental groups are great enough to be statistically significant. If differences are found to be statistically significant, it means that the probability [likelihood] that these differences occurred solely due to chance is relatively low. Most researchers agree that a significance value of .05 or less [i.e., there is a 95% probability that the differences are real] sufficiently determines significance.
Subcultures -- ethnic, regional, economic, or social groups exhibiting characteristic patterns of behavior sufficient to distinguish them from the larger society to which they belong.
Testing -- the act of gathering and processing information about individuals' ability, skill, understanding, or knowledge under controlled conditions.
Theory -- a general explanation about a specific behavior or set of events that is based on known principles and serves to organize related events in a meaningful way. A theory is not as specific as a hypothesis.
Treatment -- the stimulus given to a dependent variable.
Trend Samples -- method of sampling different groups of people at different points in time from the same population.
Triangulation -- a multi-method or pluralistic approach, using different methods in order to focus on the research topic from different viewpoints and to produce a multi-faceted set of data. Also used to check the validity of findings from any one method.
Unit of Analysis -- the basic observable entity or phenomenon being analyzed by a study and for which data are collected in the form of variables.
Validity -- the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure. A method can be reliable, consistently measuring the same thing, but not valid.
Variable -- any characteristic or trait that can vary from one person to another [race, gender, academic major] or for one person over time [age, political beliefs].
Weighted Scores -- scores in which the components are modified by different multipliers to reflect their relative importance.
White Paper -- an authoritative report that often states the position or philosophy about a social, political, or other subject, or a general explanation of an architecture, framework, or product technology written by a group of researchers. A white paper seeks to contain unbiased information and analysis regarding a business or policy problem that the researchers may be facing.

Manuscript Preparation

A Must-see for Researchers! How to Ensure Inclusivity in Your Scientific Writing

4 minute read

Table of Contents

Highly influential research findings have several real-world implications that affect the public’s perception of individuals and communities to some extent. The way science is communicated shapes people’s behavior, interactions, and even related policies. As a result, in recent years there has been a growing recognition of the need to foster inclusive language within scholarly communication, which can help avoid bias or misunderstanding.

Researchers, especially the younger generation, are becoming increasingly aware of the significance of using inclusive language in academic writing. This approach helps create a collaborative global academic landscape, while fostering respect for diverse perspectives. It is also conducive to the wide dissemination of papers and supports researchers in their long-term academic endeavors.

This article will explain why and how to use inclusive language in your manuscript. Also, it will help researchers improve their ability to choose words with precision when writing by providing examples of appropriate inclusive terms. Let’s have a look!

1. Referring to Persons with Disabilities¹

When referring to someone with a disability, it is important to focus on the person first, not highlight their condition . Avoid using the terms “disabled person” or “handicapped person.” Instead, use person-first language, such as “a person with disability,” “a person with hearing loss,” etc.

Additionally, when referring to individuals without disabilities, avoid using terms such as “normal” or “typical.” Instead, use phrases like “individuals without disabilities” or “people without disabilities.”

Example of inclusive language : Students with disabilities often encounter distinct challenges in academic settings. These can range from physical barriers like inaccessible buildings to difficulties accessing educational materials in suitable formats. In contrast, students without disabilities typically navigate the educational environment with fewer hindrances.

2. Using Gendered Nouns

Gendered nouns such as “man” or words ending in “-man” can exclude certain groups, so it is best to avoid them² . Fortunately, they can be easily substituted with neutral terms . For instance, instead of writing “man”, write “person” or “individual” and instead of writing “mankind,” write “humanity” or “human beings.”

When discussing people’s occupational roles, using neutral language is essential. For example, instead of writing “policeman,” write “police officer,” and instead of writing “chairman,” write “chairperson.”

Example of gendered noun use:  The chairman oversees the company’s operations.

Example of inclusive language:  The chairperson oversees the company’s operations.

3. Using Pronouns

When you know a person’s preferred pronoun, it is easy to incorporate it into writing. For example, most people use the pronouns he/him or she/her. However, using pronouns can become tricky in neutral or ambiguous contexts. In the past, it was common to use the  generic he   in these situations³ . However, it is best to avoid this practice as it can be exclusionary .

Here are some tips to avoid the  generic he³ :

Don’t only use he/his, add she/her

For example, do not write:  An early career researcher needs mentors. He can learn the secrets to making an impact in academia with someone more experienced.

Instead, write:  An early career researcher needs mentors. He or she can learn the secrets to making an impact in academia with someone more experienced.

Eliminate the pronoun if possible

For example, do not write:  We returned his manuscript two days after submission.

Instead, write:  We returned the manuscript two days after submission.

Use a plural term

For example, do not write:  When an author revises his manuscript , he should consider the feedback provided by the peer reviewers.

Instead, write:  When authors revise their manuscripts , they should consider the feedback provided by the peer reviewers.

4. Describing Age

As a general rule, refrain from mentioning a person’s age unless it is absolutely necessary for the context . In scientific writing, it is acceptable to use broad terms , such as infants, children, young adults, or older adults, to categorize age groups⁴ . This approach maintains inclusivity and respects individuals regardless of their age.

Conclusion

Embracing inclusive language in scholarly communication fosters a more welcoming environment for scholars from diverse backgrounds. It ensures that everyone, regardless of their life experiences, can equally benefit from advancements in science. It is worth noting that inclusive language constantly evolves with social development, which poses a great challenge for authors in terms of their English skills and the ability to pay attention to social trends.
