Literature Review SSCI 306

A literature review discusses published information in a particular subject area, and sometimes information within a certain time period.

It is not just a simple summary of the sources It also has an organizational pattern and combines both summary and synthesis

• A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory. (Remember: Conference notes, Conventions, Dissertations, etc.)

• By so doing, literature review provides a description, summary, and critical evaluation of works in relation to the research problem being investigated.

• Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study.

The main focus of an academic research paper is to develop a new argument, The focus of a literature review, however, is to summarize and synthesize the arguments and ideas of others without adding new contributions.

Why Do We Write Literature Reviews? Literature reviews provide you with a handy guide to a particular topic.

How Is A Literature Review Different From An Academic Research Paper?

“A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories.

A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:

• Give a new interpretation of old material or combine new with old interpretations,

• Trace the intellectual progression of the field, including major debates,

• Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or

• Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.

The purpose of a literature review is to:

• Place each work in the context of its contribution to understanding the research problem being studied. • Describe the relationship of each work to the others under consideration. • Identify new ways to interpret prior research. • Reveal any gaps that exist in the literature. • Resolve conflicts amongst seemingly contradictory previous studies. • Identify areas of prior scholarship to prevent duplication of effort. • Point the way in fulfilling a need for additional research. • Locate your own research within the context of existing literature [very important].

It is important to think of knowledge in a given field as consisting of three layers.

• First, there are the primary studies that researchers conduct and publish.

• Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies.

• Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally that become part of the lore of field.

What are the types of literature review?

Types of Literature Reviews

Argumentative Review

Argumentative review selectively examines the literature in order to support or refute an argument, or deeply imbedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint.

Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse.

However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews.

Types of Literature Reviews

Integrative Review

Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.

Types of Literature Reviews

Historical Review

Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.

A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.

Types of Literature Reviews

Methodological Review

Systematic Review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem. Typically it focuses on a very specific empirical question, often posed in a cause- and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.

Types of Literature Reviews

Theoretical Review

Types of Literature Reviews

The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.

“Thinking About Your Literature ReviewThe structure of a literature review should include the following: • An overview of the subject, issue, or theory under consideration, along with the

objectives of the literature review, • Division of works under review into themes or categories • An explanation of how each work is similar to and how it varies from the others, • Conclusions as to which pieces are best considered in their argument, are most

convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.

The critical evaluation of each work should consider:

• Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?

• Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?

• Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?

• Persuasiveness -- which of the author's theses are most convincing or least convincing?

• Value -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?

Development of the Literature Review

Four Stages 1. Problem formulation -- which topic or field is being examined and what are its component issues?

2. literature search -- finding materials relevant to the subject being explored.

3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic.

4. analysis anD interPretation -- discussing the findings and conclusions of pertinent literature.

“ Consider the following issues before writing the literature review:

Clarify

If your assignment is not very specific about what form your literature review should take, seek clarification from your professor by asking these questions:

1. Roughly how many sources should I include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources? 5. Should I provide subheadings and other background information, such as definitions and/or a history?

Find Models

Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read are also excellent entry points into your own research.

The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make your job easier if you first limit scope of the research problem. A good strategy is to begin by searching the Pfau Library Data Bases for books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role of “settlements”, or look in the index for the pages where these illegal settlements are mentioned, examined, reviewed, etc.

Narrow the Topic

Consider Whether Your Sources are Current

Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.
