Research Topic

Definition:

Research topic is a specific subject or area of interest that a researcher wants to investigate or explore in-depth through research. It is the overarching theme or question that guides a research project and helps to focus the research activities towards a clear objective.

How to Choose Research Topic

You can Choose a Research Topic by following the below guide:

Identify your Interests

One of the most important factors to consider when choosing a research topic is your personal interest. This is because you will be spending a considerable amount of time researching and writing about the topic, so it’s essential that you are genuinely interested and passionate about it. Start by brainstorming a list of potential research topics based on your interests, hobbies, or areas of expertise. You can also consider the courses that you’ve enjoyed the most or the topics that have stood out to you in your readings.

Review the Literature

Before deciding on a research topic, you need to understand what has already been written about it. Conducting a preliminary review of the existing literature in your field can help you identify gaps in knowledge, inconsistencies in findings, or unanswered questions that you can explore further. You can do this by reading academic articles, books, and other relevant sources in your field. Make notes of the themes or topics that emerge and use this information to guide your research question.

Consult with your Advisor

Your academic advisor or a mentor in your field can provide you with valuable insights and guidance on choosing a research topic. They can help you identify areas of interest, suggest potential research questions, and provide feedback on the feasibility of your research proposal. They can also direct you towards relevant literature and resources that can help you develop your research further.

Consider the Scope and Feasibility

The research topic you choose should be manageable within the time and resource constraints of your project. Be mindful of the scope of your research and ensure that you are not trying to tackle a topic that is too broad or too narrow. If your topic is too broad, you may find it challenging to conduct a comprehensive analysis, while if it’s too narrow, you may struggle to find enough material to support your research.

Brainstorm with Peers

Discussing potential research topics with your peers or colleagues can help you generate new ideas and perspectives. They may have insights or expertise that you haven’t considered, and their feedback can help you refine your research question. You can also join academic groups or attend conferences in your field to network with other researchers and get inspiration for your research.

Consider the Relevance

Choose a research topic that is relevant to your field of study and has the potential to contribute to the existing knowledge. You can consider the latest trends and emerging issues in your field to identify topics that are both relevant and interesting. Conducting research on a topic that is timely and relevant can also increase the likelihood of getting published or presenting your research at conferences.

Keep an Open Mind

While it’s essential to choose a research topic that aligns with your interests and expertise, you should also be open to exploring new ideas or topics that may be outside of your comfort zone. Consider researching a topic that challenges your assumptions or introduces new perspectives that you haven’t considered before. You may discover new insights or perspectives that can enrich your research and contribute to your growth as a researcher.

Components of Research Topic

A research topic typically consists of several components that help to define and clarify the subject matter of the research project. These components include:

• Research problem or question: This is the central issue or inquiry that the research seeks to address. It should be well-defined and focused, with clear boundaries that limit the scope of the research.
• Background and context: This component provides the necessary background information and context for the research topic. It explains why the research problem or question is important, relevant, and timely. It may also include a literature review that summarizes the existing research on the topic.
• Objectives or goals : This component outlines the specific objectives or goals that the research seeks to achieve. It should be clear and concise, and should align with the research problem or question.
• Methodology : This component describes the research methods and techniques that will be used to collect and analyze data. It should be detailed enough to provide a clear understanding of how the research will be conducted, including the sampling method, data collection tools, and statistical analyses.
• Significance or contribution : This component explains the significance or contribution of the research topic. It should demonstrate how the research will add to the existing knowledge in the field, and how it will benefit practitioners, policymakers, or society at large.
• Limitations: This component outlines the limitations of the research, including any potential biases, assumptions, or constraints. It should be transparent and honest about the potential shortcomings of the research, and how these limitations will be addressed.
• Expected outcomes or findings : This component provides an overview of the expected outcomes or findings of the research project. It should be realistic and based on the research objectives and methodology.

Purpose of Research Topic

The purpose of a research topic is to identify a specific area of inquiry that the researcher wants to explore and investigate. A research topic is typically a broad area of interest that requires further exploration and refinement through the research process. It provides a clear focus and direction for the research project, and helps to define the research questions and objectives. A well-defined research topic also helps to ensure that the research is relevant and useful, and can contribute to the existing body of knowledge in the field. Ultimately, the purpose of a research topic is to generate new insights, knowledge, and understanding about a particular phenomenon, issue, or problem.

Characteristics of Research Topic

some common characteristics of a well-defined research topic include:

• Relevance : A research topic should be relevant and significant to the field of study and address a current issue, problem, or gap in knowledge.
• Specificity : A research topic should be specific enough to allow for a focused investigation and clear understanding of the research question.
• Feasibility : A research topic should be feasible, meaning it should be possible to carry out the research within the given constraints of time, resources, and expertise.
• Novelty : A research topic should add to the existing body of knowledge by introducing new ideas, concepts, or theories.
• Clarity : A research topic should be clearly articulated and easy to understand, both for the researcher and for potential readers of the research.
• Importance : A research topic should be important and have practical implications for the field or society as a whole.
• Significance : A research topic should be significant and have the potential to generate new insights and understanding in the field.

How to Identify and Develop a Topic: .

How to identify and develop a topic.

It is difficult to define a topic with much specificity before starting your research. But until you define your topic, you won't know where to begin your search for information and you won't know what to look for. With a well-defined topic, you can focus your search strategies to find lots of relevant information without also finding a lot of useless stuff.

Selecting a topic to research is not a one-step task. Identifying and developing your topic is an ongoing process that does not end until you have finished your research project. Start with an idea you are interested in. Find and read some background information to get a better understanding of the topic, then use what you have learned to search for more specific information. Refine (broaden, narrow, refocus, or change) your topic, and try another search.  

Find a Topic

If you weren't assigned a specific topic and can't think of one:

• talk with your class instructor (who is, after all, the reason you are doing this project in the first place)
• find something interesting in the course reading assignments
• look at the entries and index of a subject encyclopedia
• ask a librarian to help you figure out a topic  

Narrow Your Topic

The initial idea for a research topic is often too broad. If your first searches for resources are so general that you find more information than you can click a mouse at or deal with in a reasonable amount of time (i.e. before the research project is due), focus on one of the following:

• a specific period of time
• a specific geographic location
• specific individuals or groups
• a specific aspect of the subject
• the viewpoint of a specific discipline  

Make it a Question

It is often helpful to state your topic in the form of a question. Treat the research project as an attempt to find a specific answer for a specific question.  

List Main Concepts

Pull out ideas and key terms that describe your topic. You can get a better idea of these by looking up your topic in an encyclopedia or other appropriate reference work. This will give you a better understanding of your topic, which will help you figure out what sources you will need and where you will need to look to find them.  

Analyze Your Topic

Where should you look for information? From what subject or discipline perspective are you looking at this topic? Do you need scholarly or popular sources? Will you need books, articles, sound recordings, primary sources, etc.?  

Select Appropriate Tools

Which tools do you need to find the type of information you want, (e.g. the library catalog for books, subject specific indexes for journal articles, etc.) See the library's guide to How to Find and Evaluate Sources for more.  

Initial Results

After you do an initial search, you can tell some things just from the number and type of sources you find. If you get a million or so hits, you probably need to narrow your topic. If you get only a few, broaden it. If the hits seem to be irrelevant to your topic, search using different terms. Do another search and see if you get what seems to be an appropriate amount of appropriate sources. Keep refining your search until you are satisfied with your results. Then go read them.  

After reading through some of the sources you find, you will get a better understanding of the topic you are researching. With this better understanding, you can revise your initial topic and its corresponding question for which you are so diligently seeking an answer. You can also refine your search strategy: the databases you search in, the keywords or subject terms you search for, etc. Go back and try another search using your revisions. Repeat as necessary until you have done enough research to know what to ask and how to answer it.

What's the difference between 'research topic' and 'research area'?

I am writing an essay to apply for a summer research project and is supposed to write about 'general research topic that interests me' and 'area I would like to focus'. I'm kind of confused about these two terms. What's the difference?

For example, if I'm interested in computer science, where should I write it?

p.s. I have asked this question in English Language & Usage site but didn't get answer. So I suppose that these two words may only have difference in academic field?

• graduate-admissions
• summer-school

A research area is what a research topic is placed into, but is much broader than the scope of the topic. For example a research area can be human physiology, computer science (as you mentioned) or even relate to a specific field within these broader terms such as cardiac electrophysiology or machine learning respectively.

A research topic would be a specific question, hypothesis or problem you wish to investigate and answer which is under the scope of your research area. That is to say, my research area is in neuroscience/neurophysiology and my research topic is investigating the mechanisms of neuronal communication, as an example.

You would want to say topics that interest you which relate to a certain problem that you may be aware of, whereas in the research area you would want to outline your inclinations towards a particular field of academia.

While a topic is narrower than an area (for example, your area may be "solid state physics" and your topic "semiconductor tuning based on dopage"), it's probably true that for most people there is little difference between the two terms as far as colloquial usage is concerned.

In other words, don't obsess about the difference -- though, if you want, consider the "area" a broader term.

How To Find A Research Topic

If you’re struggling to get started, this step-by-step video tutorial will help you find the perfect research topic.

Research Topic FAQs

What (exactly) is a research topic.

A research topic is the subject of a research project or study – for example, a dissertation or thesis. A research topic typically takes the form of a problem to be solved, or a question to be answered.

A good research topic should be specific enough to allow for focused research and analysis. For example, if you are interested in studying the effects of climate change on agriculture, your research topic could focus on how rising temperatures have impacted crop yields in certain regions over time.

To learn more about the basics of developing a research topic, consider our free research topic ideation webinar.

What constitutes a good research topic?

A strong research topic comprises three important qualities : originality, value and feasibility.

• Originality – a good topic explores an original area or takes a novel angle on an existing area of study.
• Value – a strong research topic provides value and makes a contribution, either academically or practically.
• Feasibility – a good research topic needs to be practical and manageable, given the resource constraints you face.

To learn more about what makes for a high-quality research topic, check out this post .

What's the difference between a research topic and research problem?

A research topic and a research problem are two distinct concepts that are often confused. A research topic is a broader label that indicates the focus of the study , while a research problem is an issue or gap in knowledge within the broader field that needs to be addressed.

To illustrate this distinction, consider a student who has chosen “teenage pregnancy in the United Kingdom” as their research topic. This research topic could encompass any number of issues related to teenage pregnancy such as causes, prevention strategies, health outcomes for mothers and babies, etc.

Within this broad category (the research topic) lies potential areas of inquiry that can be explored further – these become the research problems . For example:

• What factors contribute to higher rates of teenage pregnancy in certain communities?
• How do different types of parenting styles affect teen pregnancy rates?
• What interventions have been successful in reducing teenage pregnancies?

Simply put, a key difference between a research topic and a research problem is scope ; the research topic provides an umbrella under which multiple questions can be asked, while the research problem focuses on one specific question or set of questions within that larger context.

How can I find potential research topics for my project?

There are many steps involved in the process of finding and choosing a high-quality research topic for a dissertation or thesis. We cover these steps in detail in this video (also accessible below).

How can I find quality sources for my research topic?

Finding quality sources is an essential step in the topic ideation process. To do this, you should start by researching scholarly journals, books, and other academic publications related to your topic. These sources can provide reliable information on a wide range of topics. Additionally, they may contain data or statistics that can help support your argument or conclusions.

Identifying Relevant Sources

When searching for relevant sources, it’s important to look beyond just published material; try using online databases such as Google Scholar or JSTOR to find articles from reputable journals that have been peer-reviewed by experts in the field.

You can also use search engines like Google or Bing to locate websites with useful information about your topic. However, be sure to evaluate any website before citing it as a source—look for evidence of authorship (such as an “About Us” page) and make sure the content is up-to-date and accurate before relying on it.

Evaluating Sources

Once you’ve identified potential sources for your research project, take some time to evaluate them thoroughly before deciding which ones will best serve your purpose. Consider factors such as author credibility (are they an expert in their field?), publication date (is the source current?), objectivity (does the author present both sides of an issue?) and relevance (how closely does this source relate to my specific topic?).

By researching the current literature on your topic, you can identify potential sources that will help to provide quality information. Once you’ve identified these sources, it’s time to look for a gap in the research and determine what new knowledge could be gained from further study.

How can I find a good research gap?

Finding a strong gap in the literature is an essential step when looking for potential research topics. We explain what research gaps are and how to find them in this post.

How should I evaluate potential research topics/ideas?

When evaluating potential research topics, it is important to consider the factors that make for a strong topic (we discussed these earlier). Specifically:

• Originality
• Feasibility

So, when you have a list of potential topics or ideas, assess each of them in terms of these three criteria. A good topic should take a unique angle, provide value (either to academia or practitioners), and be practical enough for you to pull off, given your limited resources.

Finally, you should also assess whether this project could lead to potential career opportunities such as internships or job offers down the line. Make sure that you are researching something that is relevant enough so that it can benefit your professional development in some way. Additionally, consider how each research topic aligns with your career goals and interests; researching something that you are passionate about can help keep motivation high throughout the process.

How can I assess the feasibility of a research topic?

When evaluating the feasibility and practicality of a research topic, it is important to consider several factors.

First, you should assess whether or not the research topic is within your area of competence. Of course, when you start out, you are not expected to be the world’s leading expert, but do should at least have some foundational knowledge.

Time commitment

When considering a research topic, you should think about how much time will be required for completion. Depending on your field of study, some topics may require more time than others due to their complexity or scope.

Additionally, if you plan on collaborating with other researchers or institutions in order to complete your project, additional considerations must be taken into account such as coordinating schedules and ensuring that all parties involved have adequate resources available.

Resources needed

It’s also critically important to consider what type of resources are necessary in order to conduct the research successfully. This includes physical materials such as lab equipment and chemicals but can also include intangible items like access to certain databases or software programs which may be necessary depending on the nature of your work. Additionally, if there are costs associated with obtaining these materials then this must also be factored into your evaluation process.

Potential risks

It’s important to consider the inherent potential risks for each potential research topic. These can include ethical risks (challenges getting ethical approval), data risks (not being able to access the data you’ll need), technical risks relating to the equipment you’ll use and funding risks (not securing the necessary financial back to undertake the research).

Step 1: Identifying and Developing a Topic

Whatever your field or discipline, the best advice to give on identifying a research topic is to choose something that you find really interesting. You will be spending an enormous amount of time with your topic, you need to be invested. Over the course of your research design, proposal and actually conducting your study, you may feel like you are really tired of your topic, however,  your interest and investment in the topic will help you persist through dissertation defense. Identifying a research topic can be challenging. Most of the research that has been completed on the process of conducting research fails to examine the preliminary stages of the interactive and self-reflective process of identifying a research topic (Wintersberger & Saunders, 2020).  You may choose a topic at the beginning of the process, and through exploring the research that has already been done, one’s own interests that are narrowed or expanded in scope, the topic will change over time (Dwarkadas & Lin, 2019). Where do I begin? According to the research, there are generally two paths to exploring your research topic, creative path and the rational path (Saunders et al., 2019).  The rational path takes a linear path and deals with questions we need to ask ourselves like: what are some timely topics in my field in the media right now?; what strengths do I bring to the research?; what are the gaps in the research about the area of research interest? (Saunders et al., 2019; Wintersberger & Saunders, 2020).The creative path is less linear in that it may include keeping a notebook of ideas based on discussion in coursework or with your peers in the field. Whichever path you take, you will inevitably have to narrow your more generalized ideas down. A great way to do that is to continue reading the literature about and around your topic looking for gaps that could be explored. Also, try engaging in meaningful discussions with experts in your field to get their take on your research ideas (Saunders et al., 2019; Wintersberger & Saunders, 2020). It is important to remember that a research topic should be (Dwarkadas & Lin, 2019; Saunders et al., 2019; Wintersberger & Saunders, 2020):

• Interesting to you.
• Realistic in that it can be completed in an appropriate amount of time.
• Relevant to your program or field of study.
• Not widely researched.

Define Your Topic

• Narrow or Broaden Your Topic

Need to Find a Topic?

What topic interests you within this subject area? It is okay to start with a general topic and, as you build your background knowledge, narrow that topic.

How specific must your topic be?

It will depend on how many relevant and trustworthy sources you find in your research. You will need enough time to read through those sources and write a satisfactory paper given the limited space (yes, even 10 pages is a limited space).

• If you find many sources, consider narrowing your topic.
• If you find few sources, consider broadening your topic.

New topics tend to have limited resources, so your research topic might have to be more general. For very new topics, make sure there are enough relevant and trustworthy sources available before committing to it. Older topics have usually been considered from many different angles, so your research topic will have to be much more specific.

State your topic as a question

This keeps your research and paper focused on the specific topic.

For example, if you are interested in finding out about how well college students speak a foreign language after going on a study abroad, you might ask, " What effect does study abroad have on the foreign language skills of college students? "

Other examples:

Broad Topic : Foreign Language Narrower Topic : Foreign language skills of college students Research Question : What effect does study abroad have on the foreign language skills of college students?

Broad Topic : William Shakespeare Narrower Topic : Film adaptations of Shakespeare plays Research Question : How has Shakespearean drama been adapted for the 20th century film medium?

Broad Topic : Endangered Species Narrower Topic : Giant Panda conservation efforts Research Question : What is currently being done to help conserve the endangered Giant Panda population?

Narrow or Broaden Your Topic

Your topic should be broad enough so you can find sufficient information but narrow enough to answer a specific question.

Narrow a broad topic by:

• A specific type, aspect, or sub-topic of the larger topic (Business > Marketing)
• Location (Marketing in the United States)
• A targeted population or age group (Marketing to teenagers in the United States)

A narrow topic may be too specific to return useful research results.

Broaden a topic by:

• A more general or related topic (a cappella works > choral works)
• Larger locations (Quebec > Canada)
• Larger populations or age groups (Guatemalan > Hispanic)

STEP 1: Define Your Topic

Think about Search Terms

Use your background information to think of appropriate search terms. Brainstorm every possible search term for your topic.Try to think of synonyms and related words for each keyword to help broaden or narrow your search.

Look at your topic. For example: ‘Are Canadian youth politically engaged?’ The keywords in this topic would be Canadian , youth , and political engagement .

These keywords can become:

• Canadian → Canada
• Youth → "young people", "young adults", or adolescents
• "Political engagement" → vote, voting, politics, elections, or "political participation"

Example: Brainstorming Search Terms

My research question was ‘Can alternative energy sources help stop global warming?’

For this question, the keywords would be alternative energy sources, and global warming. So, some search terms could be:

• global warming → climate change, temperature change, greenhouse effect
• alternative energy sources → sustainable energy, renewable energy source, alternative fuels or environmental technology

1. Background Research

• Do some background reading to understand more about the topic.
• Is there a current book or article that gives you are good overview of the topic? 
• You can use Wikipedia  for ideas, keywords for your search and important dates and issues, but do not use it as a source in your final paper, as is not an academic source. It can also include errors, so be careful. 
• Try a test search of the library's resources to see what kind of results you get. If the topic is too general, you may need to narrow it down; if it is too specific, you may need to expand your search. 
• You can also do a test search of the internet using Google. 
• Keep in mind that what you will find through the AC Library is mostly subscription based and will include content not available for free on the internet.  

Example: Picking a Subject

My assignment:.

Write a research report on a topic of your choice

My subject ideas:

• I am interested in environmental issues.
• I have read about global warming, but what are the causes?
• I wonder, what are some possible solutions?
• Why is it such a complicated problem and what are some of the issues that are debated by scientists?
• Is technology the solution to global warming? Or are changes in our behaviour the solution?

My broad topic for the assignment is ‘Global Warming’.

My research to narrow my topic:

• I got a good overview of the topic.
• I discovered areas of the topic that interest me and that I might want to focus on, such as the causes of global warming and the possible responses to it.
• I searched for for ‘Global warming’ in Page 1+ .
• I got too many results, because my topic is too general.
• I can find suggestions of subjects on the left side of the page, which I can use to make my subject more specific.
• In the next step, I will use what I have learned to refine my topic.

2. Refine Your Topic

Narrowing your subject to a more specific topic takes a bit of research and thought.

Here are some ideas to help you narrow your topic:

• Talk to a friend to get ideas. They may give you ideas that didn't occur to you.
• Brainstorm - think about or write down what you know about the topic. Use these as terms for your test searches. 

Use these questions:

• WHY did you choose the topic? What interests you about it?  Do you have an opinion about the issues involved?
• WHO are the information providers on this topic?  Who might publish information about it?  Who is affected by the topic? Do you know of organizations or institutions affiliated with the topic?
• WHAT are the major questions for this topic?  Is there a debate about the topic?  Are there a range of issues and viewpoints to consider?
• WHERE is your topic important: at the local, national or international level?  Are there specific places affected by the topic?
• WHEN is/was your topic important? Is it a current event or an historical issue?  Do you want to compare your topic by time periods?

(Content reproduced from MIT.edu under a Creative Commons Attribution Non-Commercial License )

• Turn your topic into a question. You will be trying to answer this question with your research. Think about something you would like to try to prove or argue.
• Make sure to pick a topic that will have enough information available. Do a preliminary search to see if there is enough information about your topic.

Example: Refining Your Topic

The subject we chose in the earlier step is ‘global warming.’ This subject is a very broad topic with many different aspects you could research. We will use the techniques above to narrow our subject to a research topic.

• Why: I am interested in environmental issues, and I am interested in how technology can be used to improve things in the future.
• Who: Many environmental journals have published research on this topic. Also, organizations such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Environment Programme publish reports on the topic.
• Which types of energy sources are best for the environment?
• Are they feasible?
• How much will they cost?
• What are the potential positive or negative effects?
• Where: This issue is important for everyone, both on local levels and on a global level.
• When: This is a current issue; it is very important today and for the future. I would like for this paper to be more future-focused.
• From these answers, I came up with possible topics, such as ‘the causes of global warming’ ‘technological solutions to global warming’, or ‘what effect does global warming have on business?’ or ‘scientific debate about global warming’
• I turned my topic into a question: ‘Can alternative energy sources help stop global warming?’
• I made sure my topic has enough information available. A quick search of library resources shows over 7,000 results related to my question.

Sample research question: Can alternative energy sources help stop global warming?

Defining Scope

Tips for identifying scope.

Once you decide on a research topic, you need to determine the scope of your topic.  The scope of a research topic is determined by how detailed you want your project to be.  This process will tell you if your topic is already too narrow or too broad.  Consider the following when determining the scope of your research topic (Leggett and Jackowski, 2012):

• What is my topic about?
• Can I define it clearly?
• What relationships does my topic have with other fields?
• Are there correlations, causes, and/or effects between my topic and other topics?
• If the amount of sources available is overwhelming, then your topic may be too broad.
• If there are limited sources on your topic, then it may be too narrow.
• Is there anything specific about the group, population, or objects that I am studying that make them stand out from the others?
• What have scholars already said about my topic and what have they concluded?
• Does the geographical location impact my topic in any way?
• The scope of a research topic depends on the page length requirements.  You might feel tempted to select a broader topic for a larger paper, but your paper will lack conciseness.

The following tips may help you identify the scope of your research topic (Center for Writing and Speaking, n.d.):

• Be flexible.  You may have to abandon ideas that do not necessarily fit with the topic you have.  Furthermore, you may need to focus your research on one of the main ideas you had for your topic, rather than all of them.
• You might be thinking "too big."  This is one of the main reasons why research topics are too broad.  This is especially true if you have to write a large paper (more than 5 pages).  The length may seem overwhelming, but choosing a big topic just to get the page length will make writing about the topic more difficult.
• Define the key terms in your topic.   What do you mean by each term?  This could help you identify a more specific subtopic that you may want to cover.  Use your definitions of the key words to formulate a narrower topic.
• Avoid vague or abstract key words in your topic, such as love, death, society, etc.   Are you referring to something specific within that term or category?  If not, then the topic is likely too broad.

The following web page from Agnes Scott College, titled "Narrowing Scope" may assist you in determining the scope of your research topic.

What is Scientific Research and How Can it be Done?

Scientific researches are studies that should be systematically planned before performing them. In this review, classification and description of scientific studies, planning stage randomisation and bias are explained.

Research conducted for the purpose of contributing towards science by the systematic collection, interpretation and evaluation of data and that, too, in a planned manner is called scientific research: a researcher is the one who conducts this research. The results obtained from a small group through scientific studies are socialised, and new information is revealed with respect to diagnosis, treatment and reliability of applications. The purpose of this review is to provide information about the definition, classification and methodology of scientific research.

Before beginning the scientific research, the researcher should determine the subject, do planning and specify the methodology. In the Declaration of Helsinki, it is stated that ‘the primary purpose of medical researches on volunteers is to understand the reasons, development and effects of diseases and develop protective, diagnostic and therapeutic interventions (method, operation and therapies). Even the best proven interventions should be evaluated continuously by investigations with regard to reliability, effectiveness, efficiency, accessibility and quality’ ( 1 ).

The questions, methods of response to questions and difficulties in scientific research may vary, but the design and structure are generally the same ( 2 ).

Classification of Scientific Research

Scientific research can be classified in several ways. Classification can be made according to the data collection techniques based on causality, relationship with time and the medium through which they are applied.

• Observational
• Experimental
• Descriptive
• Retrospective
• Prospective
• Cross-sectional
• Social descriptive research ( 3 )

Another method is to classify the research according to its descriptive or analytical features. This review is written according to this classification method.

I. Descriptive research

• Case series
• Surveillance studies

II. Analytical research

• Observational studies: cohort, case control and cross- sectional research
• Interventional research: quasi-experimental and clinical research
• Case Report: it is the most common type of descriptive study. It is the examination of a single case having a different quality in the society, e.g. conducting general anaesthesia in a pregnant patient with mucopolysaccharidosis.
• Case Series: it is the description of repetitive cases having common features. For instance; case series involving interscapular pain related to neuraxial labour analgesia. Interestingly, malignant hyperthermia cases are not accepted as case series since they are rarely seen during historical development.
• Surveillance Studies: these are the results obtained from the databases that follow and record a health problem for a certain time, e.g. the surveillance of cross-infections during anaesthesia in the intensive care unit.

Moreover, some studies may be experimental. After the researcher intervenes, the researcher waits for the result, observes and obtains data. Experimental studies are, more often, in the form of clinical trials or laboratory animal trials ( 2 ).

Analytical observational research can be classified as cohort, case-control and cross-sectional studies.

Firstly, the participants are controlled with regard to the disease under investigation. Patients are excluded from the study. Healthy participants are evaluated with regard to the exposure to the effect. Then, the group (cohort) is followed-up for a sufficient period of time with respect to the occurrence of disease, and the progress of disease is studied. The risk of the healthy participants getting sick is considered an incident. In cohort studies, the risk of disease between the groups exposed and not exposed to the effect is calculated and rated. This rate is called relative risk. Relative risk indicates the strength of exposure to the effect on the disease.

Cohort research may be observational and experimental. The follow-up of patients prospectively is called a prospective cohort study . The results are obtained after the research starts. The researcher’s following-up of cohort subjects from a certain point towards the past is called a retrospective cohort study . Prospective cohort studies are more valuable than retrospective cohort studies: this is because in the former, the researcher observes and records the data. The researcher plans the study before the research and determines what data will be used. On the other hand, in retrospective studies, the research is made on recorded data: no new data can be added.

In fact, retrospective and prospective studies are not observational. They determine the relationship between the date on which the researcher has begun the study and the disease development period. The most critical disadvantage of this type of research is that if the follow-up period is long, participants may leave the study at their own behest or due to physical conditions. Cohort studies that begin after exposure and before disease development are called ambidirectional studies . Public healthcare studies generally fall within this group, e.g. lung cancer development in smokers.

• Case-Control Studies: these studies are retrospective cohort studies. They examine the cause and effect relationship from the effect to the cause. The detection or determination of data depends on the information recorded in the past. The researcher has no control over the data ( 2 ).

Cross-sectional studies are advantageous since they can be concluded relatively quickly. It may be difficult to obtain a reliable result from such studies for rare diseases ( 2 ).

Cross-sectional studies are characterised by timing. In such studies, the exposure and result are simultaneously evaluated. While cross-sectional studies are restrictedly used in studies involving anaesthesia (since the process of exposure is limited), they can be used in studies conducted in intensive care units.

• Quasi-Experimental Research: they are conducted in cases in which a quick result is requested and the participants or research areas cannot be randomised, e.g. giving hand-wash training and comparing the frequency of nosocomial infections before and after hand wash.
• Clinical Research: they are prospective studies carried out with a control group for the purpose of comparing the effect and value of an intervention in a clinical case. Clinical study and research have the same meaning. Drugs, invasive interventions, medical devices and operations, diets, physical therapy and diagnostic tools are relevant in this context ( 6 ).

Clinical studies are conducted by a responsible researcher, generally a physician. In the research team, there may be other healthcare staff besides physicians. Clinical studies may be financed by healthcare institutes, drug companies, academic medical centres, volunteer groups, physicians, healthcare service providers and other individuals. They may be conducted in several places including hospitals, universities, physicians’ offices and community clinics based on the researcher’s requirements. The participants are made aware of the duration of the study before their inclusion. Clinical studies should include the evaluation of recommendations (drug, device and surgical) for the treatment of a disease, syndrome or a comparison of one or more applications; finding different ways for recognition of a disease or case and prevention of their recurrence ( 7 ).

Clinical Research

In this review, clinical research is explained in more detail since it is the most valuable study in scientific research.

Clinical research starts with forming a hypothesis. A hypothesis can be defined as a claim put forward about the value of a population parameter based on sampling. There are two types of hypotheses in statistics.

• H 0 hypothesis is called a control or null hypothesis. It is the hypothesis put forward in research, which implies that there is no difference between the groups under consideration. If this hypothesis is rejected at the end of the study, it indicates that a difference exists between the two treatments under consideration.
• H 1 hypothesis is called an alternative hypothesis. It is hypothesised against a null hypothesis, which implies that a difference exists between the groups under consideration. For example, consider the following hypothesis: drug A has an analgesic effect. Control or null hypothesis (H 0 ): there is no difference between drug A and placebo with regard to the analgesic effect. The alternative hypothesis (H 1 ) is applicable if a difference exists between drug A and placebo with regard to the analgesic effect.

The planning phase comes after the determination of a hypothesis. A clinical research plan is called a protocol . In a protocol, the reasons for research, number and qualities of participants, tests to be applied, study duration and what information to be gathered from the participants should be found and conformity criteria should be developed.

The selection of participant groups to be included in the study is important. Inclusion and exclusion criteria of the study for the participants should be determined. Inclusion criteria should be defined in the form of demographic characteristics (age, gender, etc.) of the participant group and the exclusion criteria as the diseases that may influence the study, age ranges, cases involving pregnancy and lactation, continuously used drugs and participants’ cooperation.

The next stage is methodology. Methodology can be grouped under subheadings, namely, the calculation of number of subjects, blinding (masking), randomisation, selection of operation to be applied, use of placebo and criteria for stopping and changing the treatment.

I. Calculation of the Number of Subjects

The entire source from which the data are obtained is called a universe or population . A small group selected from a certain universe based on certain rules and which is accepted to highly represent the universe from which it is selected is called a sample and the characteristics of the population from which the data are collected are called variables. If data is collected from the entire population, such an instance is called a parameter . Conducting a study on the sample rather than the entire population is easier and less costly. Many factors influence the determination of the sample size. Firstly, the type of variable should be determined. Variables are classified as categorical (qualitative, non-numerical) or numerical (quantitative). Individuals in categorical variables are classified according to their characteristics. Categorical variables are indicated as nominal and ordinal (ordered). In nominal variables, the application of a category depends on the researcher’s preference. For instance, a female participant can be considered first and then the male participant, or vice versa. An ordinal (ordered) variable is ordered from small to large or vice versa (e.g. ordering obese patients based on their weights-from the lightest to the heaviest or vice versa). A categorical variable may have more than one characteristic: such variables are called binary or dichotomous (e.g. a participant may be both female and obese).

If the variable has numerical (quantitative) characteristics and these characteristics cannot be categorised, then it is called a numerical variable. Numerical variables are either discrete or continuous. For example, the number of operations with spinal anaesthesia represents a discrete variable. The haemoglobin value or height represents a continuous variable.

Statistical analyses that need to be employed depend on the type of variable. The determination of variables is necessary for selecting the statistical method as well as software in SPSS. While categorical variables are presented as numbers and percentages, numerical variables are represented using measures such as mean and standard deviation. It may be necessary to use mean in categorising some cases such as the following: even though the variable is categorical (qualitative, non-numerical) when Visual Analogue Scale (VAS) is used (since a numerical value is obtained), it is classified as a numerical variable: such variables are averaged.

Clinical research is carried out on the sample and generalised to the population. Accordingly, the number of samples should be correctly determined. Different sample size formulas are used on the basis of the statistical method to be used. When the sample size increases, error probability decreases. The sample size is calculated based on the primary hypothesis. The determination of a sample size before beginning the research specifies the power of the study. Power analysis enables the acquisition of realistic results in the research, and it is used for comparing two or more clinical research methods.

Because of the difference in the formulas used in calculating power analysis and number of samples for clinical research, it facilitates the use of computer programs for making calculations.

It is necessary to know certain parameters in order to calculate the number of samples by power analysis.

• Type-I (α) and type-II (β) error levels
• Difference between groups (d-difference) and effect size (ES)
• Distribution ratio of groups
• Direction of research hypothesis (H1)

a. Type-I (α) and Type-II (β) Error (β) Levels

Two types of errors can be made while accepting or rejecting H 0 hypothesis in a hypothesis test. Type-I error (α) level is the probability of finding a difference at the end of the research when there is no difference between the two applications. In other words, it is the rejection of the hypothesis when H 0 is actually correct and it is known as α error or p value. For instance, when the size is determined, type-I error level is accepted as 0.05 or 0.01.

Another error that can be made during a hypothesis test is a type-II error. It is the acceptance of a wrongly hypothesised H 0 hypothesis. In fact, it is the probability of failing to find a difference when there is a difference between the two applications. The power of a test is the ability of that test to find a difference that actually exists. Therefore, it is related to the type-II error level.

Since the type-II error risk is expressed as β, the power of the test is defined as 1–β. When a type-II error is 0.20, the power of the test is 0.80. Type-I (α) and type-II (β) errors can be intentional. The reason to intentionally make such an error is the necessity to look at the events from the opposite perspective.

b. Difference between Groups and ES

ES is defined as the state in which statistical difference also has clinically significance: ES≥0.5 is desirable. The difference between groups is the absolute difference between the groups compared in clinical research.

c. Allocation Ratio of Groups

The allocation ratio of groups is effective in determining the number of samples. If the number of samples is desired to be determined at the lowest level, the rate should be kept as 1/1.

d. Direction of Hypothesis (H1)

The direction of hypothesis in clinical research may be one-sided or two-sided. While one-sided hypotheses hypothesis test differences in the direction of size, two-sided hypotheses hypothesis test differences without direction. The power of the test in two-sided hypotheses is lower than one-sided hypotheses.

After these four variables are determined, they are entered in the appropriate computer program and the number of samples is calculated. Statistical packaged software programs such as Statistica, NCSS and G-Power may be used for power analysis and calculating the number of samples. When the samples size is calculated, if there is a decrease in α, difference between groups, ES and number of samples, then the standard deviation increases and power decreases. The power in two-sided hypothesis is lower. It is ethically appropriate to consider the determination of sample size, particularly in animal experiments, at the beginning of the study. The phase of the study is also important in the determination of number of subjects to be included in drug studies. Usually, phase-I studies are used to determine the safety profile of a drug or product, and they are generally conducted on a few healthy volunteers. If no unacceptable toxicity is detected during phase-I studies, phase-II studies may be carried out. Phase-II studies are proof-of-concept studies conducted on a larger number (100–500) of volunteer patients. When the effectiveness of the drug or product is evident in phase-II studies, phase-III studies can be initiated. These are randomised, double-blinded, placebo or standard treatment-controlled studies. Volunteer patients are periodically followed-up with respect to the effectiveness and side effects of the drug. It can generally last 1–4 years and is valuable during licensing and releasing the drug to the general market. Then, phase-IV studies begin in which long-term safety is investigated (indication, dose, mode of application, safety, effectiveness, etc.) on thousands of volunteer patients.

II. Blinding (Masking) and Randomisation Methods

When the methodology of clinical research is prepared, precautions should be taken to prevent taking sides. For this reason, techniques such as randomisation and blinding (masking) are used. Comparative studies are the most ideal ones in clinical research.

Blinding Method

A case in which the treatments applied to participants of clinical research should be kept unknown is called the blinding method . If the participant does not know what it receives, it is called a single-blind study; if even the researcher does not know, it is called a double-blind study. When there is a probability of knowing which drug is given in the order of application, when uninformed staff administers the drug, it is called in-house blinding. In case the study drug is known in its pharmaceutical form, a double-dummy blinding test is conducted. Intravenous drug is given to one group and a placebo tablet is given to the comparison group; then, the placebo tablet is given to the group that received the intravenous drug and intravenous drug in addition to placebo tablet is given to the comparison group. In this manner, each group receives both the intravenous and tablet forms of the drug. In case a third party interested in the study is involved and it also does not know about the drug (along with the statistician), it is called third-party blinding.

Randomisation Method

The selection of patients for the study groups should be random. Randomisation methods are used for such selection, which prevent conscious or unconscious manipulations in the selection of patients ( 8 ).

No factor pertaining to the patient should provide preference of one treatment to the other during randomisation. This characteristic is the most important difference separating randomised clinical studies from prospective and synchronous studies with experimental groups. Randomisation strengthens the study design and enables the determination of reliable scientific knowledge ( 2 ).

The easiest method is simple randomisation, e.g. determination of the type of anaesthesia to be administered to a patient by tossing a coin. In this method, when the number of samples is kept high, a balanced distribution is created. When the number of samples is low, there will be an imbalance between the groups. In this case, stratification and blocking have to be added to randomisation. Stratification is the classification of patients one or more times according to prognostic features determined by the researcher and blocking is the selection of a certain number of patients for each stratification process. The number of stratification processes should be determined at the beginning of the study.

As the number of stratification processes increases, performing the study and balancing the groups become difficult. For this reason, stratification characteristics and limitations should be effectively determined at the beginning of the study. It is not mandatory for the stratifications to have equal intervals. Despite all the precautions, an imbalance might occur between the groups before beginning the research. In such circumstances, post-stratification or restandardisation may be conducted according to the prognostic factors.

The main characteristic of applying blinding (masking) and randomisation is the prevention of bias. Therefore, it is worthwhile to comprehensively examine bias at this stage.

Bias and Chicanery

While conducting clinical research, errors can be introduced voluntarily or involuntarily at a number of stages, such as design, population selection, calculating the number of samples, non-compliance with study protocol, data entry and selection of statistical method. Bias is taking sides of individuals in line with their own decisions, views and ideological preferences ( 9 ). In order for an error to lead to bias, it has to be a systematic error. Systematic errors in controlled studies generally cause the results of one group to move in a different direction as compared to the other. It has to be understood that scientific research is generally prone to errors. However, random errors (or, in other words, ‘the luck factor’-in which bias is unintended-do not lead to bias ( 10 ).

Another issue, which is different from bias, is chicanery. It is defined as voluntarily changing the interventions, results and data of patients in an unethical manner or copying data from other studies. Comparatively, bias may not be done consciously.

In case unexpected results or outliers are found while the study is analysed, if possible, such data should be re-included into the study since the complete exclusion of data from a study endangers its reliability. In such a case, evaluation needs to be made with and without outliers. It is insignificant if no difference is found. However, if there is a difference, the results with outliers are re-evaluated. If there is no error, then the outlier is included in the study (as the outlier may be a result). It should be noted that re-evaluation of data in anaesthesiology is not possible.

Statistical evaluation methods should be determined at the design stage so as not to encounter unexpected results in clinical research. The data should be evaluated before the end of the study and without entering into details in research that are time-consuming and involve several samples. This is called an interim analysis . The date of interim analysis should be determined at the beginning of the study. The purpose of making interim analysis is to prevent unnecessary cost and effort since it may be necessary to conclude the research after the interim analysis, e.g. studies in which there is no possibility to validate the hypothesis at the end or the occurrence of different side effects of the drug to be used. The accuracy of the hypothesis and number of samples are compared. Statistical significance levels in interim analysis are very important. If the data level is significant, the hypothesis is validated even if the result turns out to be insignificant after the date of the analysis.

Another important point to be considered is the necessity to conclude the participants’ treatment within the period specified in the study protocol. When the result of the study is achieved earlier and unexpected situations develop, the treatment is concluded earlier. Moreover, the participant may quit the study at its own behest, may die or unpredictable situations (e.g. pregnancy) may develop. The participant can also quit the study whenever it wants, even if the study has not ended ( 7 ).

In case the results of a study are contrary to already known or expected results, the expected quality level of the study suggesting the contradiction may be higher than the studies supporting what is known in that subject. This type of bias is called confirmation bias. The presence of well-known mechanisms and logical inference from them may create problems in the evaluation of data. This is called plausibility bias.

Another type of bias is expectation bias. If a result different from the known results has been achieved and it is against the editor’s will, it can be challenged. Bias may be introduced during the publication of studies, such as publishing only positive results, selection of study results in a way to support a view or prevention of their publication. Some editors may only publish research that extols only the positive results or results that they desire.

Bias may be introduced for advertisement or economic reasons. Economic pressure may be applied on the editor, particularly in the cases of studies involving drugs and new medical devices. This is called commercial bias.

In recent years, before beginning a study, it has been recommended to record it on the Web site www.clinicaltrials.gov for the purpose of facilitating systematic interpretation and analysis in scientific research, informing other researchers, preventing bias, provision of writing in a standard format, enhancing contribution of research results to the general literature and enabling early intervention of an institution for support. This Web site is a service of the US National Institutes of Health.

The last stage in the methodology of clinical studies is the selection of intervention to be conducted. Placebo use assumes an important place in interventions. In Latin, placebo means ‘I will be fine’. In medical literature, it refers to substances that are not curative, do not have active ingredients and have various pharmaceutical forms. Although placebos do not have active drug characteristic, they have shown effective analgesic characteristics, particularly in algology applications; further, its use prevents bias in comparative studies. If a placebo has a positive impact on a participant, it is called the placebo effect ; on the contrary, if it has a negative impact, it is called the nocebo effect . Another type of therapy that can be used in clinical research is sham application. Although a researcher does not cure the patient, the researcher may compare those who receive therapy and undergo sham. It has been seen that sham therapies also exhibit a placebo effect. In particular, sham therapies are used in acupuncture applications ( 11 ). While placebo is a substance, sham is a type of clinical application.

Ethically, the patient has to receive appropriate therapy. For this reason, if its use prevents effective treatment, it causes great problem with regard to patient health and legalities.

Before medical research is conducted with human subjects, predictable risks, drawbacks and benefits must be evaluated for individuals or groups participating in the study. Precautions must be taken for reducing the risk to a minimum level. The risks during the study should be followed, evaluated and recorded by the researcher ( 1 ).

After the methodology for a clinical study is determined, dealing with the ‘Ethics Committee’ forms the next stage. The purpose of the ethics committee is to protect the rights, safety and well-being of volunteers taking part in the clinical research, considering the scientific method and concerns of society. The ethics committee examines the studies presented in time, comprehensively and independently, with regard to ethics and science; in line with the Declaration of Helsinki and following national and international standards concerning ‘Good Clinical Practice’. The method to be followed in the formation of the ethics committee should be developed without any kind of prejudice and to examine the applications with regard to ethics and science within the framework of the ethics committee, Regulation on Clinical Trials and Good Clinical Practice ( www.iku.com ). The necessary documents to be presented to the ethics committee are research protocol, volunteer consent form, budget contract, Declaration of Helsinki, curriculum vitae of researchers, similar or explanatory literature samples, supporting institution approval certificate and patient follow-up form.

Only one sister/brother, mother, father, son/daughter and wife/husband can take charge in the same ethics committee. A rector, vice rector, dean, deputy dean, provincial healthcare director and chief physician cannot be members of the ethics committee.

Members of the ethics committee can work as researchers or coordinators in clinical research. However, during research meetings in which members of the ethics committee are researchers or coordinators, they must leave the session and they cannot sign-off on decisions. If the number of members in the ethics committee for a particular research is so high that it is impossible to take a decision, the clinical research is presented to another ethics committee in the same province. If there is no ethics committee in the same province, an ethics committee in the closest settlement is found.

Thereafter, researchers need to inform the participants using an informed consent form. This form should explain the content of clinical study, potential benefits of the study, alternatives and risks (if any). It should be easy, comprehensible, conforming to spelling rules and written in plain language understandable by the participant.

This form assists the participants in taking a decision regarding participation in the study. It should aim to protect the participants. The participant should be included in the study only after it signs the informed consent form; the participant can quit the study whenever required, even when the study has not ended ( 7 ).

Importance of Narrowing the Research Topic

Whether you are assigned a general issue to investigate, must choose a problem to study from a list given to you by your professor, or you have to identify your own topic to investigate framed only by the class you are taking, it is important that the scope of the research problem is not too broad, otherwise, it will be difficult to adequately address the topic in the space and time allowed. You could experience a number of problems if your topic is too broad, including:

• You find too many information sources and, as a consequence, it is difficult to decide what to include or exclude or what are the most relevant sources.
• You find information that is too general and, as a consequence, it is difficult to develop a clear framework for examining the research problem.
• A lack of sufficient parameters that clearly define the research problem makes it difficult to identify and apply the proper methods needed to analyze the topic.
• You find information that covers a wide variety of concepts or ideas that can't be integrated into one paper and, as a consequence, you trail off into unnecessary tangents.

Strategies for Narrowing the Research Topic

A common challenge when beginning to write a research paper is determining how and in what ways to narrow down your topic . Even if your professor gives you a specific topic to study, it will almost never be so specific that you won’t have to narrow it down at least to some degree [besides, it is very boring to grade fifty papers that are all about the exact same thing!].

A topic is too broad to be manageable when a review of the literature reveals too many different, and oftentimes conflicting or only remotely related, ideas about how to investigate the research problem. Although you will want to start the writing process by considering a variety of different approaches to studying the research problem, you will need to narrow the focus of your investigation at some point early in the writing process. This way, you don't attempt to do too much in one paper.

Here are some strategies to help narrow the thematic focus of your paper :

• Aspect -- choose one lens through which to view the research problem, or look at just one facet of it [e.g., rather than studying the role of food in South Asian religious rituals, study the role of food in Hindu marriage ceremonies, or, the role of one particular type of food among several religions].
• Components -- determine if your initial variable or unit of analysis can be broken into smaller parts, which can then be analyzed more precisely [e.g., a study of tobacco use among adolescents can focus on just chewing tobacco rather than all forms of usage or, rather than adolescents in general, focus on female adolescents in a certain age range who choose to use tobacco].
• Methodology -- the way in which you gather information can reduce the domain of interpretive analysis needed to address the research problem [e.g., a single case study can be designed to generate data that does not require as extensive an explanation as using multiple cases].
• Place -- generally, the smaller the geographic unit of analysis, the more narrow the focus [e.g., rather than study trade relations issues in West Africa, study trade relations between Niger and Cameroon as a case study that helps to explain economic problems in the region].
• Relationship -- ask yourself how do two or more different perspectives or variables relate to one another. Designing a study around the relationships between specific variables can help constrict the scope of analysis [e.g., cause/effect, compare/contrast, contemporary/historical, group/individual, child/adult, opinion/reason, problem/solution].
• Time -- the shorter the time period of the study, the more narrow the focus [e.g., restricting the study of trade relations between Niger and Cameroon to only the period of 2010 - 2020].
• Type -- focus your topic in terms of a specific type or class of people, places, or phenomena [e.g., a study of developing safer traffic patterns near schools can focus on SUVs, or just student drivers, or just the timing of traffic signals in the area].
• Combination -- use two or more of the above strategies to focus your topic more narrowly.

NOTE: Apply one of the above strategies first in designing your study to determine if that gives you a manageable research problem to investigate. You will know if the problem is manageable by reviewing the literature on your more narrowed problem and assessing whether prior research is sufficient to move forward in your study [i.e., not too much, not too little]. Be careful, however, because combining multiple strategies risks creating the opposite problem--your problem becomes too narrowly defined and you can't locate enough research or data to support your study.

Research Process: An Overview: Refining Your Topic

TIP: Be Flexible

It is common to modify your topic during the research process. You can never be sure of what you may find. You may find too much and need to narrow your focus, or too little and need to broaden your focus. This is a normal part of the research process. When researching, you may not wish to change your topic, but you may decide that some other aspect of the topic is more interesting or manageable.

Steps to Refining Your Topic

Once you have chosen a general topic idea the next step is to refine your topic and ulitmately to formulate a research question.

Consider the points below to keep your research focused and on track.  If you continue to have difficulties defining a topic talk to your instructor or a librarian.

The Research Question

Once you have the topic you would like to research, the next step is forming your research question. Your research question should be focused and specifc.  The result should also be a question for which there are two or more possible answers.  See some examples below:

Assignment Guidelines

Before selecting your topic, make sure you know what your final project should look like. Each instructor will probably have different assignment requirements so be sure to read your assignment thoroughly and check for specific guidelines concerning:

• The number of sources you are required to use
• The kinds of sources are you able to use - books vs. web sites vs. journal articles or a variety?
• The type of research you are you being asked to conduct. - original research or review what research has been done?
• The length of your final project - two-pages, ten pages, etc. or an informal, five minute presentation?
• The depth of your project - Is your project an overview of the subject or in-depth and focused coverage of a specific aspect?
• The scope you are required to cover - Is this an historical summary or a report of current developments?

You instructor will probably provide specific requirements for your assignment, if not the table below may provide a rough guide:

Assigning Limits to Your Topic

A topic will be very difficult to research if it is too broad or narrow. One way to narrow a broad topic is to assign limits to what you will cover. Some common ways to limit a topic are listed below using the broad topic, "the environment" as an example.

Remember that a topic may be too difficult to research if it is too:

• locally confined - Topics this specific may only be covered in these (local) newspapers, if at all.

Example: What sources of pollution affect the Genesee County water supply?

• recent - If a topic is quite recent, books or journal articles may not be available, but newspaper or magazine articles may. Also, Web sites related to the topic may or may not be available.
• broadly interdisciplinary - You could be overwhelmed with superficial information.

Example: How can the environment contribute to the culture, politics and society of the Western states?

Selecting a Research Topic: Refine your topic

• Refine your topic
• Background information & facts

Narrow your topic's scope

Too much information?  Make your results list more manageable.  Less, but more relevant, information is key.  Here are some options to consider when narrowing the scope of your paper:

• Theoretical approach :  Limit your topic to a particular approach to the issue.  For example, if your topic concerns cloning, examine the theories surrounding of the high rate of failures in animal cloning.
• Aspect or sub-area :  Consider only one piece of the subject.  For example, if your topic is human cloning, investigate government regulation of cloning.
• Time :  Limit the time span you examine.  For example, on a topic in genetics, contrast public attitudes in the 1950's versus the 1990's.
• Population group :  Limit by age, sex, race, occupation, species or ethnic group.  For example, on a topic in genetics, examine specific traits as they affect women over 40 years of age.
• Geographical location :  A geographic analysis can provide a useful means to examine an issue.   For example, if your topic concerns cloning, investigate cloning practices in Europe or the Middle East.

Broaden your topic

Not finding enough information?  Think of related ideas, or read some background information first.  You may not be finding enough information for several reasons, including:

• Your topic is too specific .  Generalize what you are looking for. For example: if your topic is genetic diversity for a specific ethnic group in Ghana, Africa, broaden your topic by generalizing to all ethnic groups in Ghana or in West Africa.
• Your topic is too new for anything substantive to have been written.  If you're researching a recently breaking news event, you are likely to only find information about it in the news media. Be sure to search databases that contain articles from newspapers. If you are not finding enough in the news media, consider changing your topic to one that has been covered more extensively.
• You have not checked enough databases for information .  Search Our Collections to find other databases in your subject area which might cover the topic from a different perspective. Also, use excellent searching techniques to ensure you are getting the most out of every database.
• You are using less common words or too much jargon to describe your topic.  Use a thesaurus to find other terms to represent your topic. When reading background information, note how your topic is expressed in these materials. When you find citations in an article database, see how the topic is expressed by experts in the field.

Once you have a solid topic, formulate your research question or hypothesis and begin finding information.

If you need guidance with topic formulation, Ask Us !  Library staff are happy to help you focus your ideas.

Fda approves two updated covid vaccines.

New COVID Vaccines

The Food and Drug Administration Thursday gave the green light to two updated COVID-19 vaccines to help people protect themselves from the latest strains of the virus.

The new COVID vaccines are designed to keep the shots up to date with the virus, which keeps evolving to evade our immune systems.

Is COVID endemic yet? Yep, says the CDC. Here's what that means

"Vaccination continues to be the cornerstone of COVID-19 prevention," said Dr. Peter Marks , director of the FDA's Center for Biologics Evaluation and Research in a statement announcing the decision. "These updated vaccines meet the agency's rigorous, scientific standards for safety, effectiveness, and manufacturing quality. Given waning immunity of the population from previous exposure to the virus and from prior vaccination, we strongly encourage those who are eligible to consider receiving an updated COVID-19 vaccine to provide better protection against currently circulating variants."

The Pfizer-BioNTech and Moderna mRNA vaccines that got the go-ahead on Thursday target the KP.2 variant . The Novavax vaccine, which is based on an older technology, targets an earlier strain called JN.1 and is expected to get the FDA's stamp of approval soon too.

An imperfect vaccine can still provide protection

Both target strains have already been overtaken by even newer variants, but they’re all still part of the omicron group. The hope is the vaccines are close enough to boost immunity and protect people through the rest of the surprisingly big summer wave and the surge expected this winter.

“The vaccine is not intended to be perfect. It’s not going to absolutely prevent COVID-19," Marks told NPR in an interview. "But if we can prevent people from getting serious cases that end them up in emergency rooms, hospitals or worse — dead — that’s what we’re trying to do with these vaccines.”

The new vaccines should cut the risk of getting COVID by 60% to 70% and reduce the risk of getting seriously ill by 80% to 90%, Marks says. The shots are expected to become available as soon as this weekend to anyone age 6 months and older.

Vaccination timing could be a personal decision

“Right now we’re in a wave, so you’d like to get protection against what’s going on right now,” Marks says. “So I would probably get vaccinated in as timely a manner as possible. Because right now the match is reasonably close. You’re probably going to get the most benefit you’re going to get from this vaccine against what’s currently circulating. So when this gets into pharmacies I will probably be on line as soon as it gets rolled out.”

To maximize the chances of getting the best protection, people should wait at least two or three months since their last bout of COVID or their last shot to get one of the new vaccines, Marks says.

Some people could consider waiting until September or October if they’re especially concerned about maximizing protection through the winter surge and over the holidays.

“Getting vaccinated sometime in the September to early October time frame seems like a pretty reasonable thing to do to help bring you protection through the December/January time frame,” says Marks. “It doesn’t, like, suddenly stop. This is not like something that suddenly cuts off at three or four months. It’s just that the immunity will decrease with time.”

Vaccination can help slow COVID's spread

“In my opinion, everyone should get one of the new vaccines,” says Dr. George Diaz , chief of medicine at Providence Regional Medical Center Everett in Everett, Wash., and a spokesperson for the Infectious Disease Society of America. “Being vaccinated yourself will prevent transmission to other people. So that will help reduce the spread of the disease in the community, especially to the most vulnerable people. So you’re not just helping yourself but also helping others.”

In addition, getting vaccinated reduces the risk for long COVID, Diaz adds.

Others question whether everyone necessarily needs another shot, arguing most younger healthy people still probably have enough immunity from all the shots and infections they’ve already gotten to protect them from getting really sick.

“Anyone who wants to get this vaccine should get it,” says Dr. Paul Offit , a vaccine expert at the University of Pennsylvania who advises the FDA. “It certainly makes sense why someone would want to get it because it lessens your chance of getting a mild or moderate infection for about four to six months and to some extent lessens your chances of spreading the virus.” But the calculation could be different for younger people. “Were I a 35-year-old healthy adult who’d already had several doses of vaccine and one or two natural infections I wouldn’t feel compelled to get it,” Offit says.

And regardless of the public health advice, it’s far from clear how many people will want one of the new shots. Only about 22% of eligible adults got one of the last ones.

But for anyone who does want the COVID vaccine, they can get the flu shot at the same time . In addition, federal officials are recommending anyone age 75 and older also get one of the new vaccines to protect against the respiratory syncytial virus , or RSV. Same goes for pregnant people and those ages 60 to 74 who are at high risk of getting seriously ill from RSV.

Older at-risk people will probably be able to get a second shot with the new COVID vaccines in the spring or early summer to help protect them against another wave next summer.

Insured people can get all three vaccines for free if they get their shot from an in-network provider. But a federal program that paid for the vaccines for uninsured adults expired.

“In the public health community we’re very concerned about how they will access protection and looking for ways for how we’re going to solve that problem,” says Dr. Kelly Moore , who runs Immunize.org , an advocacy group. “We know that the people who are uninsured are the least likely to be able to afford becoming ill – missing work, staying home from school.”
