Primary Literature Dissertations

Secondary Literature Has been removed from its original source and repackaged Restates, rearranges, examines, or interprets information from one or more primary sources Review articles Information about primary sources Compilation or synthesis of ideas and data Should be reasonably objective (although often aren’t) Usually peer reviewed

Tertiary Literature Even Further removed from the original information than a secondary source Leads you to a secondary information Textbooks – present science theory rather than contributing to it Index to newspaper articles, an index to articles from scientific research journals, or a bibliography of an author’s original works

Let’s look at the instructions for authors from three scholarly / peer-reviewed journals…

article submission & review process Nature publication guidelines: Science publication guidelines: _info.xhtml Health Affairs publication guidelines: view.php Type of review Rigor / acceptance rate Process & criteria

Is the subject appropriate to the editorial aims and scope of the journal? Originality: does the article say something original, does it add to the body of knowledge, etc.? If a case study, is this its first use? Research methodology: most journals are concerned about this, as would be expected for an academic publisher. Is the research design, methodology, theoretical approach, critical review, etc. sound? Are the results well presented, do they correlate to the theory, and have they been correctly interpreted? Is the analysis sufficiently rigourous? Is the paper set in the context of the wider literature, are there sufficient relevant citings, are these well referenced and are other people's views credited? Is the paper accurate, is any information missing or wrong? Is the structure logical, is the sequence of the material appropriate, is there a good introduction and are the summary and conclusions adequate? Does the title of the article accurately reflect its content? How useful would the article be to a practitioner, is it a useful example of "good practice"? Could the study be replicated with similar results? Is the material clearly presented, readable? Are graphs and tables used to good effect? Is the level of detail appropriate? Is the use of terminology appropriate to the readership? Is the perspective appropriate for an international audience? Questions of format: are the abstract, keywords etc. appropriate? Is it an appropriate length (note: many journals will stipulate length requirements in their author guidelines)? Submissions judged on criteria such as… [Handout: analyzing research articles]

Does knuckle cracking lead to arthritis of the fingers? During the author’s childhood, various renowned authorities (his mother, several aunts, and, later, his mother-in law [personal communication]) informed him that cracking his knuckles would lead to arthritis of the fingers. To test the accuracy of this hypothesis, the following study was undertaken. For 50 years, the author cracked the knuckles of his left hand at least twice a day, leaving those on the right as a control. Thus, the knuckles on the left were cracked at least 36,500 times, while those on the right cracked rarely and spontaneously. At the end of the 50 years, the hands were compared for the presence of arthritis. There was no arthritis in either hand, and no apparent differences between the two hands. Knuckle cracking did not lead to arthritis after a 50-year controlled study by the one participant. While a larger group would be necessary to confirm this result, this preliminary investigation suggests a lack of correlation between knuckle cracking and the development of arthritis of the fingers. A search of the literature revealed only one previous paper on this subject, and the authors came to the same conclusion (Swezey RL. Swezey SE. The consequences of habitual knuckle cracking. West J Med 1973;122:377-9.). This result calls into question whether other parental beliefs, e.g., the importance of eating spinach, are also flawed. Further investigation is likely warranted. In conclusion, there is no apparent relationship between knuckle cracking and the subsequent development of arthritis of the fingers. This study was done entirely at the author’s expense, with no grants from any governmental or pharmaceutical source. Donald L. Unger, MD, Thousand Oaks, CA

What is a literature review? Critical look at existing research relevant to your question in order to Identify the problem Develop a hypothesis Develop a method It is NOT just a summary of a series of research papers You must evaluate the research papers and show the relationships between different work

What is a literature review? Approach it with the following questions What do we already know in the area concerned? What are the key concepts? What are the existing theories? What are the inconsistencies? What evidence is lacking, inconclusive, contradictory or too limited? What views need to be tested further?

How to Write a Literature Review Background Introduce to topic to the reader Make it interesting and easily understandable by explaining it in plain language and relating to actual or potential applications Explain scientific principles underlying the topic Define and justify the scope of the review – i.e. your question

How to Write a Literature Review Critique of the Literature Do not give a summary paper by paper Deal with themes and try to draw together the results from several papers into each theme. Use sub-headings to identify your themes Try and create a logical progression through the subject/argument Use what you have learnt about research design to critically evaluate the results of the papers you are discussing

How to Write a Literature Review Tables and Figures Tables can be a useful, concise way of summarising the findings of a number of similar studies You must cite the sources of the information Use tables alongside your evaluation of the data in the text, not instead of it Figures and diagrams can be very useful to explain important principles Cite source of information

How to Write a Literature Review Conclusions Should be short and concise What is your opinion Further Research Finish your review with some ideas for further research that needs to be done in the area and why.
