What is a Dissertation?

A dissertation is a complex and comprehensive academic project students must complete towards the end of their degree programme. It requires deep independent research on a topic approved by your tutor. A dissertation contains five chapters – introduction, literature review, methodology, discussion, and conclusion. This is the standard structure for a dissertation unless stated otherwise by your tutor or institution.

Writing a Dissertation Proposal

After selecting a topic, the next step is preparing a proposal. A dissertation proposal is a plan or outline of the research you intend to conduct. It gives a background to the topic, lays out your research aims and objectives, and gives details of the research methodology you intend to use.

If your university accepts your proposal, you can start work on the dissertation paper. If it’s not accepted at first, make amendments to the proposal based on your supervisor’s feedback.

Referencing

Referencing is not some little detail at the end of the paper. Without correct referencing, even a brilliant paper can fail miserably. Citing every source accurately is an absolute must.

Don't Neglect Small Details.

Completing a dissertation proves you can carry out something thoroughly. Therefore, you should attend to each part of the dissertation and omit nothing.

Things like creating a table of contents with the page numbers listed, the reference list, and appendices are all parts of a dissertation. They all contribute to your grade. Look at our dissertation samples and writing guides to get a good understanding.

Choosing Your Dissertation Topic

Choosing a dissertation topic is the first step towards writing a dissertation. However, you should make sure the topic is relevant to your degree programme. It should investigate a specific problem and contribute towards the existing literature.

In order to stay motivated throughout the process, the research topic should be in line with your interests. At ResearchProspect, our expert academics can provide you with unique, manageable topics so you can choose one that suits your needs. Whether you’re an undergraduate or postgraduate student, topics from ResearchProspect can go a long way towards helping you achieve your desired grade.

How to Write a Dissertation

Acceptance of your dissertation proposal is the starting signal. Check out our dissertation writing service and look through our thesis samples to grasp the typical writing style.

Structure of a Dissertation

You have a topic and it’s been accepted. Now comes the structure and format. The first chapter will introduce the topic, the second should then explore it deeply and discuss relevant models, frameworks, and concepts.

The third chapter is where you explain your methodology in detail. The fourth and fifth chapters are for discussing the results and concluding the research, respectively.

The NU Dissertation Template provides a lot of helpful info, but students still often have many questions and need additional guidance.  Seeing completed examples helps a lot.  This guide will help you to access completed NU dissertations in the NU library to inspire and inform your own research and writing.

Accessing completed NU dissertations can help students with the following common issues:

• Finding examples/inspiration for methodology, focus, topic, and other “big-picture” concerns.
• Identifying specifics on length/depth/breadth of each section of the dissertation.
• Seeing examples of formatting in context, such as APA style headings.
• Understanding specific dissertation committee expectations.
• Finding new references on completed reference lists.
• Supporting your peers’ scholarly work by reading their dissertations and participating in the scholarly community.

It’s easy to locate completed NU dissertations in the NU Library!

• Click on ProQuest Dissertations & Theses @ Northcentral University .

Narrow your search

Once you have located the published NU dissertations, you can narrow your search, just like you would with any other library resource.  Try the following strategies to start:

• Keywords/terms that you are using in your own research.
• General area of focus (for example, “Special Education”).
• Methodological approach (for example, “Phenomenology”).
• Dates (Tip – Consider narrowing your search to only the past 5 years).
• Advisors (Dissertation Chairs).
• Committee members.
• References/citations you plan to use.
• Just like with any other library resource, you can perform an advanced search using a combination of these strategies.
• In addition to the NU dissertations, you may want to consider accessing non-NU dissertations via the general ProQuest link on the pull-down menu (see steps outlined above).  This can be helpful if your topic is extremely specific, if you are very far along in your work, and if you need to broaden your search.

Now that you have accessed the completed NU Dissertations in the NU Library, the possibilities to inspire and guide you in your own work are endless.  Be excited that one day soon, your own dissertation will be published in the NU library!

How To Write A Research Proposal

A Straightforward How-To Guide (With Examples)

By: Derek Jansen (MBA) | Reviewed By: Dr. Eunice Rautenbach | August 2019 (Updated April 2023)

Writing up a strong research proposal for a dissertation or thesis is much like a marriage proposal. It’s a task that calls on you to win somebody over and persuade them that what you’re planning is a great idea. An idea they’re happy to say ‘yes’ to. This means that your dissertation proposal needs to be   persuasive ,   attractive   and well-planned. In this post, I’ll show you how to write a winning dissertation proposal, from scratch.

Before you start:

– Understand exactly what a research proposal is – Ask yourself these 4 questions

The 5 essential ingredients:

• The title/topic
• The introduction chapter
• The scope/delimitations
• Preliminary literature review
• Design/ methodology
• Practical considerations and risks 

What Is A Research Proposal?

The research proposal is literally that: a written document that communicates what you propose to research, in a concise format. It’s where you put all that stuff that’s spinning around in your head down on to paper, in a logical, convincing fashion.

Convincing   is the keyword here, as your research proposal needs to convince the assessor that your research is   clearly articulated   (i.e., a clear research question) ,   worth doing   (i.e., is unique and valuable enough to justify the effort), and   doable   within the restrictions you’ll face (time limits, budget, skill limits, etc.). If your proposal does not address these three criteria, your research won’t be approved, no matter how “exciting” the research idea might be.

PS – if you’re completely new to proposal writing, we’ve got a detailed walkthrough video covering two successful research proposals here . 

How do I know I’m ready?

Before starting the writing process, you need to   ask yourself 4 important questions .  If you can’t answer them succinctly and confidently, you’re not ready – you need to go back and think more deeply about your dissertation topic .

You should be able to answer the following 4 questions before starting your dissertation or thesis research proposal:

• WHAT is my main research question? (the topic)
• WHO cares and why is this important? (the justification)
• WHAT data would I need to answer this question, and how will I analyse it? (the research design)
• HOW will I manage the completion of this research, within the given timelines? (project and risk management)

If you can’t answer these questions clearly and concisely,   you’re not yet ready   to write your research proposal – revisit our   post on choosing a topic .

If you can, that’s great – it’s time to start writing up your dissertation proposal. Next, I’ll discuss what needs to go into your research proposal, and how to structure it all into an intuitive, convincing document with a linear narrative.

The 5 Essential Ingredients

Research proposals can vary in style between institutions and disciplines, but here I’ll share with you a   handy 5-section structure   you can use. These 5 sections directly address the core questions we spoke about earlier, ensuring that you present a convincing proposal. If your institution already provides a proposal template, there will likely be substantial overlap with this, so you’ll still get value from reading on.

For each section discussed below, make sure you use headers and sub-headers (ideally, numbered headers) to help the reader navigate through your document, and to support them when they need to revisit a previous section. Don’t just present an endless wall of text, paragraph after paragraph after paragraph…

Top Tip:   Use MS Word Styles to format headings. This will allow you to be clear about whether a sub-heading is level 2, 3, or 4. Additionally, you can view your document in ‘outline view’ which will show you only your headings. This makes it much easier to check your structure, shift things around and make decisions about where a section needs to sit. You can also generate a 100% accurate table of contents using Word’s automatic functionality.

Ingredient #1 – Topic/Title Header

Your research proposal’s title should be your main research question in its simplest form, possibly with a sub-heading providing basic details on the specifics of the study. For example:

“Compliance with equality legislation in the charity sector: a study of the ‘reasonable adjustments’ made in three London care homes”

As you can see, this title provides a clear indication of what the research is about, in broad terms. It paints a high-level picture for the first-time reader, which gives them a taste of what to expect.   Always aim for a clear, concise title . Don’t feel the need to capture every detail of your research in your title – your proposal will fill in the gaps.

Need a helping hand?

Ingredient #2 – Introduction

In this section of your research proposal, you’ll expand on what you’ve communicated in the title, by providing a few paragraphs which offer more detail about your research topic. Importantly, the focus here is the   topic   – what will you research and why is that worth researching? This is not the place to discuss methodology, practicalities, etc. – you’ll do that later.

You should cover the following:

• An overview of the   broad area   you’ll be researching – introduce the reader to key concepts and language
• An explanation of the   specific (narrower) area   you’ll be focusing, and why you’ll be focusing there
• Your research   aims   and   objectives
• Your   research question (s) and sub-questions (if applicable)

Importantly, you should aim to use short sentences and plain language – don’t babble on with extensive jargon, acronyms and complex language. Assume that the reader is an intelligent layman – not a subject area specialist (even if they are). Remember that the   best writing is writing that can be easily understood   and digested. Keep it simple.

Note that some universities may want some extra bits and pieces in your introduction section. For example, personal development objectives, a structural outline, etc. Check your brief to see if there are any other details they expect in your proposal, and make sure you find a place for these.

Ingredient #3 – Scope

Next, you’ll need to specify what the scope of your research will be – this is also known as the delimitations . In other words, you need to make it clear what you will be covering and, more importantly, what you won’t be covering in your research. Simply put, this is about ring fencing your research topic so that you have a laser-sharp focus.

All too often, students feel the need to go broad and try to address as many issues as possible, in the interest of producing comprehensive research. Whilst this is admirable, it’s a mistake. By tightly refining your scope, you’ll enable yourself to   go deep   with your research, which is what you need to earn good marks. If your scope is too broad, you’re likely going to land up with superficial research (which won’t earn marks), so don’t be afraid to narrow things down.

Ingredient #4 – Literature Review

In this section of your research proposal, you need to provide a (relatively) brief discussion of the existing literature. Naturally, this will not be as comprehensive as the literature review in your actual dissertation, but it will lay the foundation for that. In fact, if you put in the effort at this stage, you’ll make your life a lot easier when it’s time to write your actual literature review chapter.

There are a few things you need to achieve in this section:

• Demonstrate that you’ve done your reading and are   familiar with the current state of the research   in your topic area.
• Show that   there’s a clear gap   for your specific research – i.e., show that your topic is sufficiently unique and will add value to the existing research.
• Show how the existing research has shaped your thinking regarding   research design . For example, you might use scales or questionnaires from previous studies.

When you write up your literature review, keep these three objectives front of mind, especially number two (revealing the gap in the literature), so that your literature review has a   clear purpose and direction . Everything you write should be contributing towards one (or more) of these objectives in some way. If it doesn’t, you need to ask yourself whether it’s truly needed.

Top Tip:  Don’t fall into the trap of just describing the main pieces of literature, for example, “A says this, B says that, C also says that…” and so on. Merely describing the literature provides no value. Instead, you need to   synthesise   it, and use it to address the three objectives above.

Ingredient #5 – Research Methodology

Now that you’ve clearly explained both your intended research topic (in the introduction) and the existing research it will draw on (in the literature review section), it’s time to get practical and explain exactly how you’ll be carrying out your own research. In other words, your research methodology.

In this section, you’ll need to   answer two critical questions :

• How   will you design your research? I.e., what research methodology will you adopt, what will your sample be, how will you collect data, etc.
• Why   have you chosen this design? I.e., why does this approach suit your specific research aims, objectives and questions?

In other words, this is not just about explaining WHAT you’ll be doing, it’s also about explaining WHY. In fact, the   justification is the most important part , because that justification is how you demonstrate a good understanding of research design (which is what assessors want to see).

Some essential design choices you need to cover in your research proposal include:

• Your intended research philosophy (e.g., positivism, interpretivism or pragmatism )
• What methodological approach you’ll be taking (e.g., qualitative , quantitative or mixed )
• The details of your sample (e.g., sample size, who they are, who they represent, etc.)
• What data you plan to collect (i.e. data about what, in what form?)
• How you plan to collect it (e.g., surveys , interviews , focus groups, etc.)
• How you plan to analyse it (e.g., regression analysis, thematic analysis , etc.)
• Ethical adherence (i.e., does this research satisfy all ethical requirements of your institution, or does it need further approval?)

This list is not exhaustive – these are just some core attributes of research design. Check with your institution what level of detail they expect. The “ research onion ” by Saunders et al (2009) provides a good summary of the various design choices you ultimately need to make – you can   read more about that here .

Don’t forget the practicalities…

In addition to the technical aspects, you will need to address the   practical   side of the project. In other words, you need to explain   what resources you’ll need   (e.g., time, money, access to equipment or software, etc.) and how you intend to secure these resources. You need to show that your project is feasible, so any “make or break” type resources need to already be secured. The success or failure of your project cannot depend on some resource which you’re not yet sure you have access to.

Another part of the practicalities discussion is   project and risk management . In other words, you need to show that you have a clear project plan to tackle your research with. Some key questions to address:

• What are the timelines for each phase of your project?
• Are the time allocations reasonable?
• What happens if something takes longer than anticipated (risk management)?
• What happens if you don’t get the response rate you expect?

A good way to demonstrate that you’ve thought this through is to include a Gantt chart and a risk register (in the appendix if word count is a problem). With these two tools, you can show that you’ve got a clear, feasible plan, and you’ve thought about and accounted for the potential risks.

Tip – Be honest about the potential difficulties – but show that you are anticipating solutions and workarounds. This is much more impressive to an assessor than an unrealistically optimistic proposal which does not anticipate any challenges whatsoever.

Final Touches: Read And Simplify

The final step is to edit and proofread your proposal – very carefully. It sounds obvious, but all too often poor editing and proofreading ruin a good proposal. Nothing is more off-putting for an assessor than a poorly edited, typo-strewn document. It sends the message that you either do not pay attention to detail, or just don’t care. Neither of these are good messages. Put the effort into editing and proofreading your proposal (or pay someone to do it for you) – it will pay dividends.

When you’re editing, watch out for ‘academese’. Many students can speak simply, passionately and clearly about their dissertation topic – but become incomprehensible the moment they turn the laptop on. You are not required to write in any kind of special, formal, complex language when you write academic work. Sure, there may be technical terms, jargon specific to your discipline, shorthand terms and so on. But, apart from those,   keep your written language very close to natural spoken language   – just as you would speak in the classroom. Imagine that you are explaining your project plans to your classmates or a family member. Remember, write for the intelligent layman, not the subject matter experts. Plain-language, concise writing is what wins hearts and minds – and marks!

Let’s Recap: Research Proposal 101

And there you have it – how to write your dissertation or thesis research proposal, from the title page to the final proof. Here’s a quick recap of the key takeaways:

• The purpose of the research proposal is to   convince   – therefore, you need to make a clear, concise argument of why your research is both worth doing and doable.
• Make sure you can ask the critical what, who, and how questions of your research   before   you put pen to paper.
• Title – provides the first taste of your research, in broad terms
• Introduction – explains what you’ll be researching in more detail
• Scope – explains the boundaries of your research
• Literature review – explains how your research fits into the existing research and why it’s unique and valuable
• Research methodology – explains and justifies how you will carry out your own research

Raman Examination for Contamination: Iron Nitrate and Propellant Evaluation

Since before the Apollo era, the rocket propulsion sector has been a key player in developing standards of cleanliness and compatibility when designing, building, and operating systems with toxic propellants. The advent of hypergols and the widespread use of propellants like N 2 O 4 , Mixed Oxides of Nitrogen (MON), and hydrazine have forced new standards to be developed to meet the ever-growing need for safety when working with dangerous substances. These systems have only continued to grow more complex and many propellant combinations remain toxic and corrosive to most substances as the industry seeks the optimal methods for deriving the most efficient, highest performing, and generally more capable. ASTM International and other standards organizations carry on documenting standards for cleaning and passivation to ensure safe use today to meet the needs of the ever-expanding propulsion industry.

This thesis aims to determine the feasibility of using Raman spectroscopy as a method of characterizing interactions between metals and propellants. First, a background of knowledge regarding the spectroscopic method, propellants, and industry practices was researched and current areas of possible application were identified. The passivation and propellant storage phases of system lifecycles were determined to be the scope and target for experimentation. A multilevel passivation study consisting of exposing three metal types to different concentrations of nitric acid for various durations was conducted to begin developing a greater understanding of the applicability of and the techniques required to make Raman spectroscopy work as a complement to the ASTM passivation verification tests. Lessons learned from this and a short-duration compatibility study with MON and similar metal samples were documented and will be used for a larger scale and longer duration compatibility study in conjunction with NASA White Sands Test Facility (WSTF). The buildup of safe and adequate facilities for such a study was undertaken, completed, and documented in this work.

The results of testing in this thesis suggest the promising and desirable non-destructive and minimally invasive features of Raman spectroscopy have the potential to be used extensively in the propulsion sector. Suggestions for developing key techniques and methods for this application are developed and outlined as they were learned throughout the study's conduction.

Rank-Based Analyses and Designs with Clustered Data

Clustered data are common in biomedical research. It is often of interest to evaluate the correlations within clusters and between variables with clustered data. Conventional approaches, including intraclass correlation coefficients (ICCs) and Pearson correlations, are commonly used in analyses with clustered data. However, these conventional approaches are sensitive to extreme values and skewness. They also depend on the scale of the data and are not applicable to ordered categorical data. In this dissertation, we define population parameters for the rank ICC and between- and within-cluster Spearman rank correlations. These definitions are natural extensions of the conventional correlations to the rank scale. We show that the total Spearman rank correlation approximates a weighted sum of between- and within-cluster Spearman rank correlations, with weights determined by the rank ICCs of the two random variables. We also describe estimation and inference for these four rank-based correlations, conduct simulations to evaluate the performance of our estimators, and illustrate their use with real data examples. Furthermore, we apply the rank ICC in the design of clustered randomized controlled trials (RCTs), proposing unified and simple sample size calculations for cluster RCTs with skewed or ordinal outcomes. Our calculation involves inflating the sample size for an adequately powered individual RCT for an ordinal outcome with a design effect that incorporates the rank ICC. For continuous outcomes, our calculation sets the number of distinct ordinal levels to the sample size. We show that with continuous data, our calculations closely approximate more complicated sample size calculations based on clustered Wilcoxon rank-sum tests. We conduct simulations to evaluate our calculations’ performance and illustrate their use in the design of two cluster RCTs, one with a skewed continuous outcome and a non-inferiority trial with an irregularly distributed count outcome.
