Manuscript Reviews
  • Guidelines for Reviewers of Scientific
    Manuscripts

3
Reviewers serve two groups
  • The editor and the journal
  • Make sure only quality work of significance is
    published
  • The author to improve the paper, not just to
    judge (constructive criticism)
  • Give helpful, honest feedback (criticize),
    specific technical comments
  • Suggest improvements,other interpretations of
    results,other experiments and approaches

4
Step 1 of review Initial assessment
  • Scan the manuscript, take notes
  • Abstract, introduction, discussion/conclusions
  • Summarize the problem, approach, conclusions
  • Ask yourself personal questions
  • Am I the right person to review this ms?
  • Is someone else better qualified?
  • Do I have a conflict of interest?
  • Do I know the author(s)?
  • Do I have time to review it well within the
    deadline?

5
Initial assessment
  • Content
  • Is the subject suitable for the journal?
  • Scientific merit
  • Is the manuscript worth publishing?
  • Is the data high quality? Is it true?
  • Significance of results
  • New knowledge, understanding, technique?
  • Is it interesting?
  • Is it a significant contribution to the field?
  • It should NOT be a simple extension or slight
    modification of past research.

6
If you will not continue the review. . .
  • State your specific reasons (personal or
    scientific)
  • Reasons to reject for publication at this stage
  • Not suitable for journal
  • Work is poorly executed or not significant
  • Poor English, writing, or organization
  • Personal

7
The review
  • Read the entire manuscript thoroughly
  • Take detailed notes they will be the outline
    for your review

8
Make an organized list of specific comments or
recommendations
  • Give location (page, paragraph, line)
  • List by importance most important first
  • This sentence/paragraph/section would be stronger
    if. . .
  • This argument would be convincing if you
    presented data. . .

9
Look for
  • Presentation
  • A story line or thread to tie entire paper and
    each section together
  • Clear, logical flow (movement) sentence to
    sentence, paragraph to paragraph, section to
    section
  • Correct amount of detail
  • For experts in the field
  • To reproduce the work

10
Presentation . . .
  • The research problem
  • Good approach to problem
  • Reasonable interpretation of results, without too
    much speculation
  • No technical errors
  • English
  • Appropriate language
  • Correct use of terminology
  • Need work before acceptance?
  • Recommend help!

11
Title
  • Accurate description of main focus
  • Should include most important aspects (key words)
  • Organism(s)
  • Technique
  • Result
  • Can length be reduced?
  • Should order of words or phrasing be changed?

    of the rce genes
  • ?
  • Molecular cloning of genes for endoglucanases
    RCE2 and RCE3 from Rhizopus oryzae and possible
    evolution of the rce genes

15
Abstract
  • Clearly outlines the main points of focus
  • One or two succinct sentences on the background
    of organisms, problem
  • Approach to solving the problem, including a
    sentence or two about technique or method
  • Results
  • One or two sentences on significance of results
    in relation to research question, our
    understanding of the problem, and/or potential
    use

16
Problems with abstracts
  • Not including the correct information (or not
    enough, e.g., just a few sentences when authors
    English is poor)
  • Including too much information
  • Not the place for an introduction
  • Methods or results too detailed
  • Including the wrong information
  • Other studies or citations should be in the
    Introduction or Discussion

17
Problems with abstracts
  • Abstract for paper written in Japanese
  • Web blight of European pear occurred in Okayama
    Pref., Japan, in July of 1989 and in October of
    1993. The pathogen obtained from infested leaves
    and sclerotia was identified as Rhizoctonia
    solani AG1-IB in respect to hyphal anastomosis
    and cultures types. The common name of Web
    blight is proposed for this new disease of
    European pear.
  • Need to identify all symptoms (others are given
    in captions), plant parts
  • Rated disease development (table), not in
    abstract
  • No mention of Kochs postulates

18
Problems with abstracts
  • Although isolation of an endoglucanase gene from
    members of the subdivision Zygomycota had not
    been reported, in a previous study, we cloned a
    new endoglucanase gene, designated the rce1 gene,
    from Rhizopus oryzae, a member of the subdivision
    Zygomycota. In this study, two endoglucanases. .
    . .

? We previously cloned a new endoglucanase gene,
rce1, from Rhizopus oryzae, the first from a
member of the subdivision Zygomycota. Two
endoglucanases. . . .

19
Introduction
  • Concise only what is necessary
  • Explain problem in relation to past work by other
    researchers and authors.
  • Compare and contrast past work.
  • New, relevant references

20
Problems with Introduction
  • Too much detail (perhaps more suitable for
    Discussion), every paper cited (should not be a
    review of the literature)
  • Includes areas not directly related to research
    question
  • Relevant papers not included

21
Materials and methods
  • Was the work done well? Described well?
  • Are there flaws in methods, artifacts in
    measurements?
  • Are techniques appropriate to answer the
    questions, address the problem?
  • Manufacturers included?

22
Methods . . .
  • Appropriate sample size, controls, and
    statistical tests?
  • Statistics included, explained well? Citations,
    programs included?

23
Problems with methods
  • Too much detail of routine methods
  • (e.g., size of flask)
  • Do not need to include every experiment
  • if poorly designed or unexpected results
    required a change in plans
  • Equations and statistics examine closely for
    accuracy, correct use

24
Results
  • Findings and observations
  • Logical order
  • Tables and figures
  • Point out important features, relationships
  • Must be suitable for the type of data

25
Problems with results
  • Poor presentation
  • Not complete
  • Not logical order
  • Not specific too general
  • Irrelevant findings
  • Are not related to research problem
  • Data in tables, figures repeated in text
  • Unnecessary tables, figures
  • Can a sentence or two explain the illustrations?

26
Problems with results
  • Not specific too general
  • Other isolates such as Alternaria alternata and
    Cladosporium species including C.
    clado-sporioides, C. oxysporum, C. tenuissimum
    and C. sphaerospermum were detected frequently
    from both cultivars and all lots. Other isolates
    such as R. stolonifer, Fusarium spp. and M.
    verrucaria were also detected at low frequencies.
    The percentages of infected or infested seeds
    were very high on new lots (Table 3), but the
    fungal flora of new lots was simpler than that of
    old ones.

27
Problems with results
  • Not specific too general
  • The percentages of infected or infested seeds
    were very high on new lots (Table 3), but the
    fungal flora of new lots was simpler than that of
    old ones.
  • Give percentages
  • What does simpler mean?
  • Suggest In new lots, ___ of the seeds were
    infected or infested, but fewer species were
    isolated.

28
Problems with results
  • Not specific too general
  • In 2003, submerged application of simeconazole in
    paddy water on 15, 22, or 29 July showed potent
    efficacy against kernel smut (Table 3) The
    highest efficacy was obtained by submerged
    application on 29 July. In 2004, the fungicide
    gave excellent control against kernel smut in
    every test (Table 4).
  • What does potent efficacy mean?
  • What is excellent control? Excellent may
    differ in percentage depending on the particular
    disease. Give specific percentage, result with
    no fungicide.

29
Tables and Figures
  • Are all tables and figures present? Are all
    mentioned in the text?
  • Note the first mention of every illustration.
  • Evaluate presentation of data
  • Is it clear and logical?
  • Necessary? Or better described in text only?
  • Is data organized well in table?
  • Are headings appropriate, placed correctly?
  • Does each column (including the first on left)
    have a heading?

30
Tables and Figures
  • Clearly labeled?
  • Key for symbols in figures?
  • Consistent with text, other tables and figures?

31
Problems with Tables and Figures
  • Unnecessary
  • Fewer than 8 data points or many zeroes, etc.
  • Incomplete captions
  • Unexplained abbreviations
  • Tables
  • No heading above 1st column on left
  • Headings with too many words
  • Figures
  • Caption not worded properly
  • Not explained clearly

32
Problems with Tables and Figures
  • Incomplete captions
  • Fig. 1. Natural symptoms on leaf of
    Europeanpear. (identify specific symptom, use
    arrow)
  • Fig. 1. Leaf blight on European pear after
    natural infection by Rhizoctonia solani in an
    orchard.
  • Fig. 5. Lesion of European pear leaf by
    artificial inoculation with R. solani.
  • Fig. 5. Lesion on European pear leaf __ days
    after inoculation with Rhizoctonia solani.
  • (Better to replace inoculation with type
    ofinoculation, inoculum, etc.)

33
Discussion
  • Should not repeat Results!
  • Dont need to repeat exact data can summarize
    trend, relevance, relationships
  • Should not repeat Introduction!
  • Logical order usually by importance
  • Places results in context of past work,
    compares/contrasts
  • Significance of results are explained well and
    are justified by the data (that is, the results
    support the conclusions)

34
Problems with Discussion
  • Repeats the Results!
  • Repeats the Introduction! Exact words!
  • Plagiarism??!!
  • Look for unusual wording, perfect English
  • Too much speculation, not enough evidence
  • Too much hedging (not willing to commit to a
    conclusion) It may possibly be that it could
    perhaps

35
Literature Cited
  • Be concerned if most are the authors own
    publications or none are recent (within 2-3 yrs)
  • Is journal style used?

36
Summary of review
  • Note
  • Other interpretations of data
  • Errors in reasoning
  • Point out problems with clarity
  • Where more explanation is needed
  • Suggest different wording

37
Summary of review. . .
  • Be helpful
  • Do not say only
  • Publish without change
  • too specializeddo not publish
  • Explain problems
  • Make specific suggestions for improvement or
    revision, additional experiments or data,
    treatment of data, statistical tests

38
Summary of review. . .
  • Confirm (or not)
  • Excellent coverage of literature and
    interpretation of results and available data
  • Identify related studies
  • Suggest methods, further experiments
  • Suggest methods for better approaches
  • Identify missed opportunities

39
  • Time for questions

40
Tables
  • Use to present specific data, relationships to
    make exact comparisons, to illustrate/make a
    point or points (idea or ideas), easier than
    describing it in the text.
  • If there are lt8 data points presented in a table,
    then the data can probably be described more
    efficiently in the text rather than in a table.
  • Text of article refers to main points of table,
    does not repeat all contents.

41
Table organization
  • Title briefly describes the experiment, data
    given, organisms and location if appropriate, and
    gives enough detail for the table to be
    understood without referring to rest of the
    article.
  • The table should contain like items or compare
    like items.
  • Comparisons should be down columns, not across
    lines (across rows) it is easier to read and
    compare down, rather than across.

42
Table organization
  • Use headings and subheadings to organize the
    data, clearly and identify the data in each
    column.
  • Horizontal headings of columns should identify
    the dependent variables (measured variable).
    Items below the leftmost heading (stub head)
    identify the independent variables for the
    horizontal rows.
  • Every column must have a heading. Include the
    unit of measure in the heading (not after the
    data within the table)
  • Width (mm)

43
Table organization
  • Group items logically, include necessary controls
    and statistics.
  • Define all nonstandard abbreviations and symbols
    (in caption or footnotes).
  • Label footnotes with superscript letters (not
    numbers, which can be mistaken for exponents in
    the table), from left to right, top to bottom.

44
Tables Critical points
  • Verify all data! Check accuracy, consistency
    with text and other tables and figures (including
    labels, units of measure, abbreviations, and
    fonts).
  • Can a reader understand the table without reading
    the article? The table must be able to stand
    alone.
  • Simplify as much as possible.
  • Proofread, proofread, proofread.

45
Figure checklist
  • Figure text and axis labels
  • __ Between 6 and 10 pt
  • __ Lightface type recommended (i.e., plain, not
    boldface)

    capitalization style)

46
Figure checklist
  • __ Units in parentheses at end of axis labels
    Length (mm)

  • __ Axis label c. 0.2 cm from units on axis, no
    more than 0.5 cm x- and y-axis labels
    equidistant from axes

47
Figure Checklist
  • __ All appropriate words and letters in italics
    (e.g., genus, species, section, 1-letter
    constants and variables)
  • __ Space before and after all operation signs
    (e.g., , ) with equations and definitions, use
    en dash (width of two hyphens) for minus sign.
  • __ Make sure all abbreviations are consistent
    from figure to figure.

48
Figure checklist
  • Figure Panels
  • __ Named with capital letters, preferably inside
    each panel
  • __ Less than 0.5 cm between vertically aligned
    panels

  • __ Type of micrograph, optical system, stains,
    etc. defined in caption
  • Rules ( lines)

  • 5. The important model refers to what? The
    Altingiaceae are a family of c. 15 tree species
    with an excellent fossil record and are an
    important model for understanding Northern
    Hemisphere biogeography. In natural populations,
    there are very few experimental demonstrations
    that the number or size of seeds produced by
    plants is actually reduced in the absence of
    carbon assimilation by reproductive structures.
    By convention, a family is treated as plural,
    and a plural verb is used. In this case, the
    family was first treated as singular, then as
    plural.
