How to Write and Publish a Scientific Paper Robert A. Day Cambridge University Press 1989 FSA 3010 /PB 1

1. What is scientific writing a) Need of clarity - clearly stated problem - clearly stated conclusion New knowledge “for the first time” b) Receiving the signals Scientific communication = two ways process Need to be received – to be understood c) Understanding the signals • Purpose of Sci. Com. : to communicate new scientific findings • As clear as possible • Not literature nor poetry FSA 3010 /PB 2

• Publication = ultimate result of scientific research ⇒ same effort as for the rest • Best English = same sense in the fewest short words (no diversion, metaphors, ….) FSA 3010 /PB 3

1. Origins of Scientific Writing • Experience over 100 past years ⇒ IMRAD (first sci. Journals :1665) • Introduction Methods Results and Discussion : - Highly structured and Rigid (originality in the content not in the form - Requested by most editors because Simplest Most logical way to communicate research results • Question form : What question (problem) was studied ? Answer = Introduction - How was the problem studied ? Answer = Methods - What were the results ? Answer = Results - What do the findings mean ? Answer = Discussion - FSA 3010 /PB 4

• IMRAD = easy roadmap for authors – editors – referees – readers 1. What is a Scientific Paper • Definition : Written and published report describing original research results • Criteria(test) for VALID publication • Must be published in the right place : Primary journals (not reports, conference proceedings,…) FSA 3010 /PB 5

• Council of Biology Editors : An acceptable primary scientific publication must be the first disclosure containing sufficient information to enable peers to asses observation, - to repeat experiments, and - to evaluate intellectual processes; (conclusion justified by the data) - moreover it must be susceptible to sensory perception (printed journal, computer data base, microfilms,…), essentially permanent, available to the scientific community without restriction , and available for regular screening by one or more of the major recognized secondary services (e.g. Institute for Scientific Information,…) FSA 3010 /PB 6

• No newsletter, internal reports, proceedings of symposium (should be (re) published in Primary Journals when speculations matured to conclusions), … • Prepublication peer review (referee’s evaluation procedure) • Organization : IMRAD - M : Materials and Methods - Sometimes : Experimental section : M+R+D (in notes or short communications) - Result section different from Discussion section : Highly desirable • A scientific paper is NOT literature BUT communication of research results • No dual publication FSA 3010 /PB 7

1. Title • Importance : read by thousand of people (only few if any will read the full paper) • Need to reach its intended audience • Title = Label suitable for indexing by Abstracting / Indexing services • choice of words • order of words • Rule : fewest possible words that adequately describe the content of the paper - Not to short : need for specific title (no general) - Not to long : not an abstract - no waste words (study on …, observations on …, verb) - no abbreviations, jargon,… - avoid series titles each paper = independent cohesive study (chronology of appearance ?) better : hanging title FSA 3010 /PB 8

1. How to list the Authors • Order of names? Origin of disputes and arguments • Authorship? - takes the intellectual responsibility of the results being presented - should have made an important contribution to the study being reported (referring to original aspects ) - intellectual input : not easy to measure • More than one initial recommended • Corresponding author (reprints address, proofs, …) FSA 3010 /PB 9

1. How to prepare the Abstract • Abstract = brief summary (250 words) , Miniversion • Goal : allows the reader to decide to read or not • IMRAD structure : - state principal objectives and scope - describe the methodology employed summarize the results - - state the principal conclusions (conclusions : 3 times in Abstract, Introduction and Discussion) • Past tense because refers to work done • No references • Self contained (published by it self) • Economy of words (but no abbreviations) FSA 3010 /PB 10

1. How to write the Introduction • Should state briefly and clearly your purpose • Decide the audience • Justify why did you choose that subject and why is it important • Start writing the paper when the work is still in progress • From problem to solution (even if some redundancy with Abstract) • Suggested rules : ⇒ Present first the nature and scope of the work ⇒ Review the pertinent literature (most important background information, state of the art) ⇒ State the methods of investigation, so as the reasons for their choice FSA 3010 /PB 11

⇒ (State the principal results) ⇒ (State the principal conclusions suggested by the results) • Present tense for the established knowledge • Mention your previously published papers (abstracts, closely related papers, …) • Avoid mistake : do not keep the reader in suspense (not a detective story) • Define specialized terms and abbreviations FSA 3010 /PB 12

1. How to write the Materials and Methods Section • Purpose : Describe and justify the experimental design so that the experiments could be repeated by others (peers) • Reproducibility = basis of Science • Must give the full details (if not ⇒ rejection by the referee no matter the results) • Past tense • Chronological presentation (with sub headings) • Similar to cookbook recipes : - How ? - How much? • If new method (unpublished) : Provide all the needed details • Rule : enough information must be given so that the experiments could be reproduced by a competent colleague FSA 3010 /PB 13

• Avoid mistake : No mixing some of the results 2. How to write the Results • Result section = Core of the paper • Presentation of the data but predigested : only representative data not all quot;The fool collects facts, the wise selects themquot; • No more method description • Not yet data interpretation : the discussion section is designed to tell what they mean • No references • Crystal clarity : the whole paper will stand or fall on the basis of the results • Avoid redundancy Most common fault : repetition in the text of what is apparent in Figures or Tables • No need to cite Figures and Tables FSA 3010 /PB 14

It is clearly shown in Figure X that … = verbiage • If n variables tested, - present in Table or Graphs only those which affect the reaction - For the others: state you did not find under the experimental conditions Absence of evidence is not evidence of absence • Past tense FSA 3010 /PB 15

1. How to write the Discussion • Harder part to define and to write ← Cause of rejection • Often : many too long • Show the relationships among observed facts • Components : - Try to present the principles, relationships, generalization shown by the results not a recapitulation of the results - Point out any exceptions or any lack of correlation, define unsettled points - Show how your results and interpretations agree (or contrast )with previously published work - Don’t be timid. Discuss the theoretical implications of your work as well as any possible practical applications - State your conclusions as clear as possible FSA 3010 /PB 16

- Summarize your evidence for each conclusion • End of discussion : Short summary or Conclusion regarding the significance of the work Bad, if the reader at end asks quot; So what ?quot; • Be modest : Scientific truth ≠ whole truth Only spotlight shining on one particular area Don’t extrapolate to a bigger picture than that shown by your data • Verb tense - Present for established knowledge - Past for the new (own) results FSA 3010 /PB 17

1.How to state the Acknowledgments • Acknowledge - Technical help - Advisors, … (be specific, they are not responsible for the work) - Financial assistance (grants, fellowships, contractors, …) • Be courteous We thank … NOT we wish to thank FSA 3010 /PB 18

1.References • Avoid secondary materials (only significant, published references) • Read carefully “the instruction to authors” of the journal • Place it at the point of the sentence to whish it applies (not all at the end of sentences) FSA 3010 /PB 19
