Background (What you should know ?)

• Integral part of a researcher’sprofessional life.

• Getting a paper published can be avery tedious and time-consumingprocess.

• Challenging to start writing a newpaper and to remain motivatedduring the process.

Page 3: Scientific writing and publication

Background (What you should know ?)• Scientific papers have to meet

certain requirements regarding howthe paper was written and the wayit is published.

• A scientific paper must be a validpublication

• Editors and publishers expect astandard form and structure ofsubmitted papers.

Page 4: Scientific writing and publication

Background (What you should know ?)• The form may vary considerably by

type of paper (e.g. a case study ispresented in a different form from asurvey paper), but the basic buildingblocks are similar.

• Before writing, we should be clearabout the primary researchobjectives and key findings of thepaper.

Page 5: Scientific writing and publication

How to get Started ?• Before wondering “How to Start?”,

think about “When and Where”

• What environment inspires you?

• Where are you most concentratedand least distracted?

• What day of the week and whattime of the day do you find mostfruitful for writing?

Page 6: Scientific writing and publication

How to get Started ?

Set aside time for writing

INTERMEDIATE GOAL• Submit to Co-authors

FINAL GOAL• Submit to the Journal

Page 7: Scientific writing and publication

How to get Started ?• Make use of writing sessions and

sufficient short and long breaks.

• Reward yourself for achievingintermediate- and long-term goals

SCIENTIFIC WRITING

Page 9: Scientific writing and publication

Format of the Scientific Paper

• Title and abstract• Introduction• Methods• Results• Discussion• Conclusion• Acknowledgments• References

Page 10: Scientific writing and publication

Title

Page 11: Scientific writing and publication

Title• Fewest possible words that

adequately describe the contents ofthe paper.

• First Impression of the paper

• Electronic search databases usewords in the title and abstract toyield search results.

Page 12: Scientific writing and publication

Title (Effective Titles)• identify the main issue of the paper;

• are accurate, clear, specific andcomplete;

• do not contain abbreviations unlessthey are well known by the targetaudience;

• attract readers.

Page 13: Scientific writing and publication

Title (Effective Titles from Keywords)• Take a quiet moment to re-read

your paper and write down thekeywords of the different sections.

• Use the keywords and active verbsto formulate several potential titles.

• Try to write the most importantkeywords at the beginning of thetitle, as readers’ attention is focusedon the beginning.

Page 14: Scientific writing and publication

Abstract

Page 15: Scientific writing and publication

Abstract• Use the keywords of each section of

the paper to construct the abstract.

• Always state the objective of yourstudy at the beginning.

• Try to use short phrases, simplelanguage, and common wordcombinations, and avoid the passivevoice as much as possible.

Page 16: Scientific writing and publication

AbstractCheck if the abstract covers the 4 Ws:

• Background: What is known andwhy is this study needed?

• Methods: What did you do?

• Results: What did you find?

• Conclusion: What does it mean?

Page 17: Scientific writing and publication

Abstract• Does not contain any bibliography,

figures, tables, abbreviations.

• Generally written after the paper isprepared.

• Keywords are the important wordsfound in the research paper.

• Written below the abstract (3 to 6)

Page 18: Scientific writing and publication

AbstractCritically revise abstract every time the main text

undergoes revisions.

Page 19: Scientific writing and publication

Introduction

Page 20: Scientific writing and publication

Introduction• Today many editors and reviewers

prefer short and focusedintroductions.

• The introduction does not have amaximum word count like theabstract but should be as concise aspossible, typically not more than 10to 15% of the full word count of thepaper.

Page 21: Scientific writing and publication

IntroductionThe structure of an introduction canbe visualized as a funnel.

• The broadest part at the toprepresents the general context of thestudy topic (Background).

• It then narrows down to more topicalcontextual information.

• Ends with the specific rationale of thestudy and, vitally, the aim, purpose, orobjective.

Page 22: Scientific writing and publication

IntroductionCheck if the introduction has afunnel shape with clear sections on:• General background (what is this all

about?);• What is known and what is

unknown about this specific subject(why was this study needed, andwhy is it important?);

• Primary research question (what didwe want to know?); and

• Study aim and design (what did wedo to answer the researchquestion?).

Page 23: Scientific writing and publication

Methods

Page 24: Scientific writing and publication

Methods• Includes basic information on study

design, setting and subjects, datacollection, data analysis, and ethicalapproval.

• It is quite common to use suchsubheadings to structure the section.

• In the case of research in humans, theauthority providing ethical clearanceneeds to be stated as well.

Page 25: Scientific writing and publication

Methods

• Refer to previous publicationsfrom the same large researchproject, such as a study protocol,for additional information.

• Ask yourself, ‘‘Would a researcherbe able to re-produce the studywith the information I provide inthis paper?’’

Page 26: Scientific writing and publication

MethodsMention the design of the present study

Page 27: Scientific writing and publication

Methods

Explain:• when and where the study was

conducted• how the sample was recruited or

selected, and• which inclusion and exclusion

criteria were applied.

• Provide a sample size calculation forstudies to statistically test a specifichypothesis.

Page 28: Scientific writing and publication

Methods• Match the part on data analysis

with the research questions.

• If you present a primary researchquestion in your introduction andone or more secondary questions,start by explaining the primaryanalysis, followed by the secondaryanalyses.

• Provide sufficient detail on thestatistical techniques you used.

Page 29: Scientific writing and publication

Results

Page 30: Scientific writing and publication

Results• Clear, concise and objective

description of the findings.

• Mostly written in past tense.

• Findings are presented withoutinterpretation.

• For every method (What you did),there should be a correspondingresult (What you found).

Page 31: Scientific writing and publication

Results

• Findings in the results sectionshould match and answer theresearch questions from theintroduction, using the proceduresexplained in the methods section.

• Use tables and figures tosupport the main text of the resultssection.

Page 32: Scientific writing and publication

Results

• Use more tables and figures tosupport the main text of the resultssection.

• Findings in the results section should match andanswer the research questions from the introduction,using the procedures explained in the methods section.

Page 33: Scientific writing and publication

Tables and Figures

Page 34: Scientific writing and publication

Tables and Figures• Tables and figures are an efficient

way of presenting findings froma study.

• If they are designed well, theyprovide more information thanwords.

• A paper’s key findings should bepresented in tables and figures, asreaders will look at them to get anoverview of the study results.

Page 35: Scientific writing and publication

Tables and Figures• Importantly, they must be self-

explanatory; a reader should beable to fully understand theinformation without having to readthe text

• Most journals allow only a limitednumber of tables and figures to bepart of the print version of a paper(often around 5-6).

Page 36: Scientific writing and publication

Tables and Figures• It is highly recommended to

design the layout of tables andfigures carefully;

• A clear and suitable layoutemphasizes the credibility of thestudy results, which is essential forthe peer-reviewing process.

Page 37: Scientific writing and publication

Tables and Figures• Note that permission is needed if

you want to use a figure created bysomebody else.

• Both tables and figures should havea clear relation with the text of thepaper.

• They should be referred to in thetext in a chronological order startingwith 1 (e.g., ‘‘Table 1 shows .;’’‘‘We observed . (Figure 1)’’).

Page 38: Scientific writing and publication

Tables and Figures

• The title of a table is usuallypresented at the top, whereas thatof a figure is usually placed at thebottom.

• Check whether the target journalrequires submitting tables orfigures as separate files andwhether figures must have aspecific file format (e.g., TIFF, JPEG,or PNG) to avoid unnecessary work.

Page 39: Scientific writing and publication

Tables and Figures• Journals usually charge for

Colored Illustrations,

• So unless you do not mind spendingmoney on this, prepare black-and-white or gray-scale figures.

• Check whether the scales andfigures are distinguishable afterprinting.

Page 40: Scientific writing and publication

Tables and Figures• When designing tables, use

horizontal lines to mark thetop and bottom and to separate thecolumn headings from the body, butno vertical lines as far aspossible.

• Use landscape page formatfor wide tables.

Page 41: Scientific writing and publication

Discussion

Page 42: Scientific writing and publication

DiscussionThe purpose of the discussion sectionis to:• Give the reader a summary of the

main findings,• To put them into context by

comparing with previous work and• Discussing future implications and

any shortcomings of the researchdesign.

Page 43: Scientific writing and publication

Discussion

• Although the structure of theintroduction can be visualized as afunnel, the discussion can bevisualized as an inverted funnel.

• Thus, the introduction anddiscussion together form anhourglass shape.

Page 44: Scientific writing and publication

Discussion

The discussion starts with:• The narrowest part by answering

the research question in thesummary of main findings,

• It then gradually widens out tocomparisons with other studies and

• the interpretation of the studyfindings in the wider context of thestudy topic.

Page 45: Scientific writing and publication

Discussion• The discussion section should never

present any new results.

• Start by presenting the mainfindings, by answering the researchquestion in exactly the same way asyou stated it in the introductionsection.

• Do not waste words by repeatingresults in detail.

Page 46: Scientific writing and publication

Discussion• Mention unexpected findings by

stating that they were unexpectedand did not relate to a priorhypothesis; such honesty willstrengthen your paper.

• Include a separate subsection aboutthe strengths and weaknesses ofthe study.

• Every study has its limitations, andyou should make sure to mentionthem.

Page 47: Scientific writing and publication

Discussion• When comparing with other

studies, discuss the reasons fordifferences and similarities withyour results,

• Mention the limitations of thosestudies, but be respectful andobjective,

• Try to stress what your data adds tothe existing body of evidence.

Page 48: Scientific writing and publication

DiscussionIt is appropriate to use• ‘‘may’’ or ‘‘might.’’• ‘‘Show,’’• ‘‘demonstrate,’’• ‘‘suggest’’

than using ‘‘prove,’’ which canhardly ever be used in research.

Page 49: Scientific writing and publication

Discussion• Never, ever(!), just write that

further research is needed; this ispractically the same as telling peoplenot to forget to breathe.

• Formulate possible implications (forclinical practice and/or research,depending on the focus of the paper).

• Embrace the uniqueness of thisspecific study and always remember tostick to the original storyline of thepaper.

Page 50: Scientific writing and publication

Discussion• End the discussion section with a

conclusion presenting your findingsin light of the evidence in the fieldand the specific strengths andlimitations of your research.

• Try to think of it as the one-liner(citable statement) that readersmust remember when havingseen your work.

Page 51: Scientific writing and publication

Conclusion

Page 52: Scientific writing and publication

Conclusion• Conclusion should be directly from

the data presented.

• No extra materials should beintroduced.

• The major function of conclusion isto make RECOMMENDATIONSbased on the results of the study.

Page 53: Scientific writing and publication

Acknowledgment

Page 54: Scientific writing and publication

Acknowledgment• Technical Help from Individuals

• Laboratory and Staffs

• Sources of special equipment

• Financial Assistance

(Grants, Fellowships)

Page 55: Scientific writing and publication

References

Page 56: Scientific writing and publication

References• Science moves forward by building

on the research work of others, so itis important to appropriately citeprevious work.

• Purpose is to enable the readers toconsult the original sources.

• Only references should be cited thathas been actually consulted.

Page 57: Scientific writing and publication

References

• Organizing references can be timeconsuming.

• Most researchers work withreference management software,

• This allows them to organize, store,and download references of anytype (scientific papers, books, webpages, and other publication types)at all times.

Page 58: Scientific writing and publication

References• Most of these software's

support automatic importingof references from databasessuch as PubMed.

• Any references added to acitation manager canbe easily inserted into thetext of the paper.

Page 59: Scientific writing and publication

References• When pieces of text are moved

around during revisions, thereference management softwarewill automatically re-order thereferences.

• Papers that have been accepted butnot yet published can be cited as

‘‘in press.’’

Page 60: Scientific writing and publication

ReferencesConsider choosing the reference which• Provides the highest level of evidence,• is open-access available,• has been most recently published, or• has been published in the journal to

which you are submitting yourmanuscript.

• The latter will demonstrate to editorsthat you know and read their journal.

Page 61: Scientific writing and publication

Authorship

Page 62: Scientific writing and publication

Authorship• Being an author of a scientific

paper and having a key role as anauthor can help your CAREER.

• It is therefore unsurprising thatauthorship is a highly debatedissue in meeting rooms andaround coffee machines atacademic departments.

Page 63: Scientific writing and publication

Authorship

• The first author is the mostimportant position, followed by thelast author (supervisor) and thesecond author.

• The corresponding author is theprimary contact person forquestions related to the underlyingwork, during the editorial processand after publication.

Page 64: Scientific writing and publication

AuthorshipCheck and follow ICMJE criteriaon contributorship andauthorship. Authors should have• contributed substantially to the

conception and design, dataanalysis and interpretation of data;

• contributed to writing the paper orrevising it critically for importantintellectual content; and

• given final approval of the version tobe published.

Page 65: Scientific writing and publication

Authorship• Ask coauthors to critically review

and provide feedback with targetedquestions and set them deadlines torespond.

• Ask coauthors to meticulously checktheir names, initials, and affiliationsbefore submitting.

PART II

PUBLICATION

Page 68: Scientific writing and publication

Choosing a Journal

Page 69: Scientific writing and publication

Choosing a Journal• In a scientific paper, you try to tell a

story, but to whom?

• Your audience will largely dependon the journal you publish yourwork in.

• PubMed alone cites more than 20million papers.

• Choosing the right journal for yourwork is not easy.

Page 70: Scientific writing and publication

Choosing a Journal• Acceptance rates vary from under 10%

for the most prestigious journals tomore than 80% for some journals.

• The impact factor of a journal reflectsthe average number of citations ofarticles published in the journal in thepast 2 years.

• The Impact Factor is calculated bydividing the number of citations in theJCR year by the total number ofarticles published in the two previousyears.

Page 71: Scientific writing and publication

Choosing a Journal• The number of electronic journals

without printed formats is everincreasing as well as being able topublish papers very soon afteracceptance.

• Many scientific journals arenowadays open access.

• Although many journals(traditional and electronic) docharge some fees.

Page 72: Scientific writing and publication

Choosing a Journal• There have been reported cases of

mock journals and fake publisherssending out e-mail invitationsto submit papers, while only beinginterested in pocketing publicationfees.

• Proper scientific journals will notnormally send such e-mails.

Page 73: Scientific writing and publication

Choosing a Journal

• Think about a target journalbefore you start writing.

• Look at the journals’ web sites andauthor’s instruction.

• See if a journal actually publishesthe type of paper you intend towrite.

Page 74: Scientific writing and publication

Choosing a Journal• Balance the desire to publish in high

impact factor journals with yourpreferred time to publication.

• Submitting a paper to a journal witha high rejection rate may giveyou useful reviewer reports butmay also delay your publicationprocess by several months asmultiple submissions may benecessary.

Page 75: Scientific writing and publication

Choosing a Journal• If you want to publish in a specific

journal, be sure to read the journalguidelines.

• Discuss relevant target journals,prioritize them and rank a final listof 3-5 journals.

• This will enable you to focus on yourfirst journal of choice

Page 76: Scientific writing and publication

Submitting a paper

Page 77: Scientific writing and publication

Submitting a paper

• Each journal has its own specificrequirements for paper, which canbe found in the author instructionson the journal’s Web site.

• Every journal has slightly differentrequirements regarding aspects likethe maximum number of words,the reference style to use orwhether tables and figures shouldbe embedded in the paper orsubmitted separately.

Page 78: Scientific writing and publication

Submitting a paper• The cover letter accompanies the

submission of your paper and may bethe first that an editor reads.

• Therefore, it should stress thesignificance of the paper for the fieldof research and the relevance to thespecific journal.

• The cover letter also confirmsadherence to the journal’s authorrequirements and contains anyadditional information that may be ofinterest to the editor.

Page 79: Scientific writing and publication

Submitting a paper• Most journals want you to suggest

at least two or three potentialreviewers for your paper who areexperts in their field.

• A journal may contact these but willoften invite additional reviewersto receive at least two good-qualityreviews.

Page 80: Scientific writing and publication

Submitting a paper• A journal’s online submission

system will guide you through thesubmission process step by step.

• Well prepared manuscripts can besubmitted within an hour or so,

• If you cannot finish the submissionin one go, the system usually allowsto save information and resumethe submission process later.

Page 81: Scientific writing and publication

Submitting a paper

• Read your full paper from beginningto end carefully one more time.

Ask yourself:• Is the story line obvious, logical, and

interesting?• Is the text clear but also concise?• Have I been consistent in the use of

terms?• Is the language correct ?

Page 82: Scientific writing and publication

Submitting a paper• Consider having your manuscript

proofread by a trusted peer.

• Such a peer is able to identify the‘‘blind spots’’ in the manuscript,which you and your coauthors haveoverlooked and to give valuablefeedback for final improvements ofthe manuscript.

• In case your mother tongue is notEnglish, it can be useful to have yourpaper checked by a native speaker or aprofessional language editing service.

Page 83: Scientific writing and publication

Submitting a paper• Use the cover letter as an opportunity

to ‘‘sell your paper’’ to the editor, whowill ultimately decide on it.

Write a convincing cover letterincluding the following elements:• the paper’s title and your request to

submit for publication;• significance of the main findings for

the field;• relevance to the journal’s audience;• information required by the journal;

and• additional issues related to the paper.

Page 84: Scientific writing and publication

Submitting a paper

• Once you have finished yoursubmission, you should archive allinformation from the submissionprocess.

• Monitor the status of yoursubmission regularly and contactthe journal if the status is unclear orwhen a decision is taking too long(example: when you have not heardfrom the journal in 2-3 months).

Page 85: Scientific writing and publication

Responding to reviewers

Page 86: Scientific writing and publication

Responding to reviewers

There are three types of editorialdecisions about submitted papers:

• Acceptance – RARE !!!

• Rejection (immediately by thejournal’s editor or after peerreview),

• Revision (usually with peerreview).

Page 87: Scientific writing and publication

Responding to reviewers

• Receiving a ‘‘revise andresubmit’’ decision proves that ajournal is interested, which is goodnews.

• It means there is a good chance ofacceptation if you respondsatisfactorily to the reviewers’comments.

Page 88: Scientific writing and publication

Responding to reviewers• Do not panic when receiving a‘‘reject after review’’decision!

• Be aware that papers are moreoften rejected than accepted.

• Reviewer reports will give you freeadvice on how to improve yourpaper.

Page 89: Scientific writing and publication

Responding to reviewers

• Once you have received thedecision, read it, sleep on it, andread it again, reflecting on thereasons for rejection.

• Share the rejection decision withyour coauthors, and use theopportunity to further strengthenyour manuscript before submittingit to a different journal.

Page 90: Scientific writing and publication

Responding to reviewers• When receiving a ‘‘revise and

resubmit’’ decision, read the reportcarefully and let it sink in beforewriting the response.

• Copy/paste all comments into a newdocument and respond to eachcomment according to the followingstructure:

• Author’s response: briefly respond tothe criticism

• Changes to the paper: state whetherand where in the paper you have maderevisions.

Page 91: Scientific writing and publication

Responding to reviewers

• In your revised paper, mark thetext that has been changed sincethe previous version,

• For example, using the ‘‘trackchanges’’ option of your wordprocessor.

• Always be respectful toward thereviewers in your response to theircomments.

Page 92: Scientific writing and publication

Responding to reviewers

• Provide solid arguments to supportyour point of view, includingreferences to evidence from yourown data or previously publishedwork.

• In any case, reviewers reading yourresponse and the revised papershould get the impression thatyou have taken their commentsseriously and that you have doneyour best to improve the paperaccordingly.

Page 93: Scientific writing and publication

Responding to reviewers

• Add a word of thanks to eachreviewer for taking the time tosuggest improvements.

• In the end, you will find that hoped-for e-mail in your inbox headed‘‘accepted for publication.’’

• Cherish that moment and be sureto CELEBRATE IT!
