» Without reviewing the existing literature, a researcher starts from a dark room, heading towards badly designed studies that are poorly carried out and produce findings of little importance.
» Similarly to policy makers and practitioners, reviews of the relevant literature will allow informed choices to be made regarding the costing, planning and implementation of proposed interventions.
» The review is therefore a part of your academic development – of becoming an expert in the field (Hart, 1998:1).
![Page 4: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/4.jpg)
Two major reasonsa. The preliminary search
This helps researcher to generate and refine research ideas.
b. The critical reviewThis is an essential part of research that requires researchers (1) to demonstrate his/her awareness of the current state of knowledge and (2) to show how his/her research fits in the wider context of research area.
![Page 5: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/5.jpg)
Major purposes» To provide foundation to build research on» To develop a good understanding and insight into relevant
previous research and emerging trends» To help researcher to identify theories and ideas that
researcher test using data (deductive approach)» To help researcher to relate his/her ideas and theories
developed through inductive approach» To help researcher to refer whether his/her research findings
are in line with the available literature or are in contrast to those
» To identify other research that may be in progress» To help avoid charges of plagiarism

Major purposesContinued from previous page
Gall et al. (1996) highlight the purposes of literature review as:» To help researcher to refine research question(s) and
objectives;» To highlight research possibilities that have been overlooked;» To discover explicit recommendations for further research;» To provide researcher superb justification for pursuing
specific research questions and objectives;» To help researcher to avoid simply repeating work that has
already been done;» To sample current opinion; » To gain an insight into research approaches, strategies and
techniques.» To organise valuable ideas and findings

Contents of literature review)(Contents to be covered)
1. To include the key academic theories within the area of research chosen;
2. To demonstrate that the researchers’ knowledge of the chosen research area is up to-date;
3. To show how this research relates to previous published research;
4. To assess the strength and weaknesses of previous work , including omissions and bias; and
5. To justify arguments by referencing previous research.

Structure of literature review(Structure to be followed)
» Start at a more general level;» Provide a brief overview of key ideas;» Summarize, compare and contrast the work of the key
writers;» Narrow down to highlight the work most relevant to
this research;» Provide a detailed account of findings of similar work; » Highlight those issues where this research will
provide fresh insights; and» Lead the readers into subsequent sections of this
research which will address such issues.

The literature review process
![Page 11: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/11.jpg)
Planning the literature searchA careful planning of literature search is needed so that
it is ensured to have relevant and up-to-date literature; this requires to take the following steps.
a. Define the parameters of the research, which are:a. Language of publication (for example English)b. Subject area (for example accountancy)c. Business sector (for example manufacturing)d. Geographical area (for example Asia)e. Publication period (for example the last 10 years)f. Literature type (for example refereed journals)

Planning the literature searchContinued from previous slide
b. Generate key words and search termsi. Key words or search terms help describe research
question(s) and objectives
ii. Using ‘Relevance Tree’ can prove a good tool in generating key words; a worked example for generating key words through ‘Relevance Tree’ is provided in ‘Reading Materials’ folder)
iii. Key words are used to search the tertiary literature
c. Discuss ideas as widely as possible
![Page 13: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/13.jpg)
Conducting the literature search
Conducting literature search may involve a variety of approaches, namely:
• Searching using tertiary literature sources;• Table 3.2 entitled “Tertiary literature
sources and their coverage” is available in ‘Reading Materials’ folder.
• Continues next slide
![Page 14: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/14.jpg)
Conducting the literature search• Obtaining relevant literature referenced in
books and journals already studies;• Scanning and browsing secondary literature
available in the libraries;• Table 3.4 entitled “Selected publishers’ and
bookshops’ Internet addresses” is available in ‘Reading Materials’ folder.
• Searching using Internet.• See next slide.

Obtaining and evaluating the literature
» Define the scope of your review
» Assess relevance and value
» Assess sufficiency
![Page 17: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/17.jpg)
Recording the literature
Make notes for each item you read
Record the following» Bibliographic details
See details in Table 3.6 available in ‘Reading Materials’ folder.
Check also Appendix 2 entitled “Systems of referencing” available in ‘Reading Materials’ folder.
» Brief summary of content(covered in slide 7 & 8)
» Supplementary informationSee details in Table 3.7 available in ‘Reading Materials’ folder.

Referencing the referencesExamples
In text:Saunders, Lewis and Thornhill (2009)
In references (or bibliography)Saunders, M.N.K, Lewis, P. and Thornhill, A. (2009) Research Methods for Business Students (5th ed), Prentice Hall
Study ‘Systems of referencing’, including the Harvard system, the American Psychological Association (APA) system and Footnotes (or Vancouver system) in ‘Reading Materials
![Page 19: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/19.jpg)
Basically, any approach that works forYOU is appropriate; one possible
procedure follows
1.Arrange your notes in a logical order. If you are having difficulty seeing an order, look for clues in the sequence of your ideas or try concept mapping the topic.
2. Identify the main ideas - sorting your notes to fit under the headings.
![Page 20: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/20.jpg)
» Develop a table of contents, that can then be fleshed out with descriptive bullet-points (annotated table of contents). By subjecting an annotated table of contents (or outline) to review, a novice researcher can receive a self leading advice on contents and structure of the planned literature review.
» Example follows………(next slde)
![Page 21: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/21.jpg)
» Example: a step-by-step, hierarchical list of the points you plan to cover, e.g., 1st main idea
•1st supporting pointevidence, argument, or exampleevidence, argument, or exampleevidence, argument, or example
•2nd supporting pointevidence, argument, or exampleevidence, argument, or exampleevidence, argument, or example
2nd main idea, etc……

» Try to avoid long lists of supporting points; combine into related ideas.
» If you can't decide where to put something, put it in two or more places in the outline.
» As you write, you can decide which place is the most appropriate.
» Now you are ready to write your review.» Introduce the topic and give a brief
statement of the ‘main ideas’.
![Page 23: PART I 3RD Critically Reviewing the Literature_2](https://reader033.vdocuments.mx/reader033/viewer/2022061514/5695cf9d1a28ab9b028ed0b4/html5/thumbnails/23.jpg)
» Write some plausible synthesis or analysis for these ideas using headings according to the step-by-step hierarchical list and guide the reader through the material.
» If the literature review is part of a research project, stop at the end of each topic, to mention the main relevant ideas and how they fit together relating to your research.
» Leave it, then reread, edit and revise what you have written, to make sure that it makes sense and 'flows' in a way that the reader will understand what you are tying to convey.
