How to measure the quality of journal Impact factor Impact factor The impact factor (IF) of an academic journal is a measure reflecting the average number of citations to recent articles published in that journal. It is frequently used as a proxy for the relative importance of a journal within its field, with journals with higher impact factors deemed to be more important than those with lower ones. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information. Impact factors are calculated yearly starting from 1975 for those journals that are indexed in the Journal Citation Reports.

Organization of a Paper Abstract Abstract Introduction Introduction Methods Methods Results Results Discussion/Conclusions Discussion/Conclusions Acknowledgements Acknowledgements References References Note: most scientific journals follow the format of the Structured Abstract. Occasionally, the Results and Discussion are combined – when the data need extensive discussion to allow the reader to follow the train of logic of the research. Note: most scientific journals follow the format of the Structured Abstract. Occasionally, the Results and Discussion are combined – when the data need extensive discussion to allow the reader to follow the train of logic of the research.

Abstract - a summary (~ words) of the Abstract - a summary (~ words) of the problem, the method, the results and the problem, the method, the results and the conclusions; the reader can decide whether or conclusions; the reader can decide whether or not to read the whole article not to read the whole article Introduction - clearly states the problem being investigated & reasons for the research; summarizes relevant research to provide context; identifies the questions being answered; briefly describes the experiment, hypothesis(es), research question(s) & general experimental design or method Introduction - clearly states the problem being investigated & reasons for the research; summarizes relevant research to provide context; identifies the questions being answered; briefly describes the experiment, hypothesis(es), research question(s) & general experimental design or method

Methods - provides the reader enough details so they can understand and replicate the research; explains how the problem was studied; identifies the procedures followed; explains new methodology in detail; includes the frequency of observations, what types of data were recorded, etc. Methods - provides the reader enough details so they can understand and replicate the research; explains how the problem was studied; identifies the procedures followed; explains new methodology in detail; includes the frequency of observations, what types of data were recorded, etc. Results - presents the findings, and explains what was found; shows how the new results are contributing to the body of scientific knowledge; follows a logical sequence based on the tables and figures presenting the findings to answer the question or hypothesis(es) Results - presents the findings, and explains what was found; shows how the new results are contributing to the body of scientific knowledge; follows a logical sequence based on the tables and figures presenting the findings to answer the question or hypothesis(es)

Discussion/Conclusions - describes what the results mean regarding what was already known about the subject; indicates how the results relate to expectations and to the literature previously cited; explains how the research has moved the body of scientific knowledge forward; outlines the next steps for further study Discussion/Conclusions - describes what the results mean regarding what was already known about the subject; indicates how the results relate to expectations and to the literature previously cited; explains how the research has moved the body of scientific knowledge forward; outlines the next steps for further study Acknowledgements – recognize various contributions of other workers Acknowledgements – recognize various contributions of other workers References - the sources of previously References - the sources of previously published work; includes information not from published work; includes information not from the experiment and not ‘common knowledge’ the experiment and not ‘common knowledge’

Actions to Take Skim the article without taking notes: Skim the article without taking notes: Read the abstract; it will tell you the major findings of the article and why they matter Read the abstract; it will tell you the major findings of the article and why they matter Read first for the ‘big picture’ Read first for the ‘big picture’ Note any terms or techniques you need to define Note any terms or techniques you need to define Jot down any questions or parts you don’t understand Jot down any questions or parts you don’t understand If you are unfamiliar with any of the key concepts in the article, look them up in a textbook If you are unfamiliar with any of the key concepts in the article, look them up in a textbook

Re-read the article more carefully especially the ‘methods’ and ‘results/conclusions’ sections: Re-read the article more carefully especially the ‘methods’ and ‘results/conclusions’ sections: Carefully examine the graphs, tables, and diagrams Carefully examine the graphs, tables, and diagrams Try to interpret the data first before reading the captions and details Try to interpret the data first before reading the captions and details Make sure you understand the article fully Make sure you understand the article fully Ask yourself questions about the study, such as: Ask yourself questions about the study, such as: What problems does the study address? Why is it important? Is the method good? Are the findings supported by evidence? Are they unique and supported by other work in the field? What problems does the study address? Why is it important? Is the method good? Are the findings supported by evidence? Are they unique and supported by other work in the field?

Write a ‘summary’ of the article Write a ‘summary’ of the article Describe the article in your own words, write down the sentences can be used in your own papers in the future (important for Chinese students) Describe the article in your own words, write down the sentences can be used in your own papers in the future (important for Chinese students) Note the ‘key points’ - purpose of the study/questions asked, assumptions, major findings & conclusions, questions unanswered & any surprises Note the ‘key points’ - purpose of the study/questions asked, assumptions, major findings & conclusions, questions unanswered & any surprises How to Read and Review a Scientific Journal Article Duke University Writing Studio twp.duke.edu/uploads/media_items/scientificarticlereview.original.pdf (accessed 05 November 2013) twp.duke.edu/uploads/media_items/scientificarticlereview.original.pdf

Other Useful Hints Draw inferences (a conclusion reached on the basis of evidence and reasoning): Draw inferences (a conclusion reached on the basis of evidence and reasoning): not everything in an article is stated explicitly; rely on your prior knowledge/experience and the background in the article, to draw inferences from the material not everything in an article is stated explicitly; rely on your prior knowledge/experience and the background in the article, to draw inferences from the material Distinguish main points: Distinguish main points: Document level: in title, abstract and keywords Document level: in title, abstract and keywords Paragraph level: look for words/phrases like unexpected, in contrast to previous work, hypothesize that, propose, introduce, data suggests Paragraph level: look for words/phrases like unexpected, in contrast to previous work, hypothesize that, propose, introduce, data suggests

Take notes as you read: Take notes as you read: this improves recall and comprehension; you may think you’ll remember everything but details will slip away this improves recall and comprehension; you may think you’ll remember everything but details will slip away develop a template for recording notes on articles develop a template for recording notes on articles can use the structured abstract format (abstract, introduction, methods, results, discussion & conclusions, references) can use the structured abstract format (abstract, introduction, methods, results, discussion & conclusions, references) How to read a scientific article: Mary Purugganan & Jan Hewitt, Rice University f (accessed 05 November 2013) f f

Difficulties in Reading Papers Papers can be poorly written Papers can be poorly written Bad writing has consequences for the reader Bad writing has consequences for the reader The reader cannot easily understand what the experiment was The reader cannot easily understand what the experiment was Lack background information or training Lack background information or training
