Authors : Jihyun Kim, Soon Kim, Hye-Min Cho, Jae Hwa Chang, Soo Young Kim

Background

Many scholarly journals have established their own data-related policies, which specify their enforcement of data sharing, the types of data to be submitted, and their procedures for making data available.

However, except for the journal impact factor and the subject area, the factors associated with the overall strength of the data sharing policies of scholarly journals remain unknown.

This study examines how factors, including impact factor, subject area, type of journal publisher, and geographical location of the publisher are related to the strength of the data sharing policy.

Methods

From each of the 178 categories of the Web of Science’s 2017 edition of Journal Citation Reports, the top journals in each quartile (Q1, Q2, Q3, and Q4) were selected in December 2018. Of the resulting 709 journals (5%), 700 in the fields of life, health, and physical sciences were selected for analysis.

Four of the authors independently reviewed the results of the journal website searches, categorized the journals’ data sharing policies, and extracted the characteristics of individual journals.

Univariable multinomial logistic regression analyses were initially conducted to determine whether there was a relationship between each factor and the strength of the data sharing policy.

Based on the univariable analyses, a multivariable model was performed to further investigate the factors related to the presence and/or strength of the policy.

Results

Of the 700 journals, 308 (44.0%) had no data sharing policy, 125 (17.9%) had a weak policy, and 267 (38.1%) had a strong policy (expecting or mandating data sharing). The impact factor quartile was positively associated with the strength of the data sharing policies.

Physical science journals were less likely to have a strong policy relative to a weak policy than Life science journals (relative risk ratio [RRR], 0.36; 95% CI [0.17–0.78]). Life science journals had a greater probability of having a weak policy relative to no policy than health science journals (RRR, 2.73; 95% CI [1.05–7.14]).

Commercial publishers were more likely to have a weak policy relative to no policy than non-commercial publishers (RRR, 7.87; 95% CI, [3.98–15.57]). Journals by publishers in Europe, including the majority of those located in the United Kingdom and the Netherlands, were more likely to have a strong data sharing policy than a weak policy (RRR, 2.99; 95% CI [1.85–4.81]).

Conclusions

These findings may account for the increase in commercial publishers’ engagement in data sharing and indicate that European national initiatives that encourage and mandate data sharing may influence the presence of a strong policy in the associated journals.

Future research needs to explore the factors associated with varied degrees in the strength of a data sharing policy as well as more diverse characteristics of journals related to the policy strength.

Pratiques de communication dans la pratique de recherche des doctorant.e.s en biologie

Posté le par

Auteur/Author : Mélodie Faury

Dans cet article, je m’intéresse à une période particulière d’un parcours de chercheur : la thèse, moment d’engagement (ou de choix de non-engagement) dans une carrière de recherche scientifique.

Les entretiens sont effectués auprès de dix doctorant.e.s en biologie expérimentale ayant tous suivi la même formation universitaire à la recherche. Lors d’un entretien, je leur propose de rendre compte de leur pratique, tout en la mettant à distance en la commentant à partir du relevé de leurs pratiques de communication quotidiennes (courriers électroniques, réunions, conversations avec différents membres du laboratoire, téléphone, séminaires, etc.).

L’étude des pratiques de communication dans les pratiques de recherche des doctorant.e.s met en évidence la fréquence et la diversité des pratiques et des situations de communication dans lesquelles les doctorant.e.s se retrouvent impliqués au cours d’une semaine.

Ces situations structurent leur travail de recherche et s’organisent autour, ou à partir, de ce qui constitue leurs principales activités en tant que doctorant.e.s : les expériences à la paillasse, en premier lieu, associées à la mise en place et à l’entretien de collaborations ; l’écriture d’articles, leur soumission pour publication et la présentation des résultats obtenus, devant les membres de l’équipe, du laboratoire ou dans le cadre de congrès, colloques ou séminaires.

La méthode d’entretien choisie est intéressante à deux titres : elle permet d’une part de rendre compte d’un quotidien peu connu de la pratique de recherche de doctorant.e.s en biologie expérimentale, et d’autre part d’appréhender le rapport des étudiants en thèse à ce qui constitue leur pratique de la recherche, par l’explication et le commentaire du relevé de leurs pratiques de communication de la semaine précédent l’entretien.

Cette approche constitue pour les chercheurs-enquêtés une première forme de mise à distance de leur pratique et une occasion d’élaborer un discours, face au chercheur-enquêteur, sur eux-mêmes, sur leur pratique et sur la science et elle me permet de saisir à un premier niveau comment se construit un « rapport identitaire et culturel aux sciences » par l’expérience vécue de la pratique (rendre compte de ce qui structure la pratique) telle qu’elle est rapportée dans les discours (parler de la pratique, la commenter et se positionner).

Research Integrity Among PhD Students at the Faculty of Medicine: A Comparison of Three Scandinavian Universities

Posté le par

Authors : Bjørn Hofmann, Lone Bredahl Jensen, Mette Brandt Eriksen, Gert Helgesson, Niklas Juth, Søren Holm

This study investigates research integrity among PhD students in health sciences at three universities in Scandinavia (Stockholm, Oslo, Odense). A questionnaire with questions on knowledge, attitudes, experiences, and behavior was distributed to PhD students and obtained a response rate of 77.7%.

About 10% of the respondents agreed that research misconduct strictly defined (such as fabrication, falsification, and plagiarism, FFP) is common in their area of research, while slightly more agreed that other forms of misconduct is common.

A nonnegligible segment of the respondents was willing to fabricate, falsify, or omit contradicting data if they believe that they are right in their overall conclusions. Up to one third reported to have added one or more authors unmerited.

Results showed a negative correlation between “good attitudes” and self-reported misconduct and a positive correlation between how frequent respondents thought that misconduct occurs and whether they reported misconduct themselves.

This reveals that existing educational and research systems partly fail to foster research integrity.

Research transparency promotion by surgical journals publishing randomised controlled trials: a survey

Posté le par

Authors : Nicolas Lombard, A. Gasmi, L. Sulpice, K. Boudjema, Damien Bergeat

Objective

To describe surgical journals’ position statements on data-sharing policies (primary objective) and to describe key features of their research transparency promotion.

Methods

Only “SURGICAL” journals with an impact factor higher than 2 (Web of Science) were eligible for the study. They were included, if there were explicit instructions for clinical trial publication in the official instructions for authors (OIA) or if they had published randomised controlled trial (RCT) between 1 January 2016 and 31 December 2018.

The primary outcome was the existence of a data-sharing policy included in the instructions for authors. Data-sharing policies were grouped into 3 categories, inclusion of data-sharing policy mandatory, optional, or not available.

Details on research transparency promotion were also collected, namely the existence of a “prospective registration of clinical trials requirement policy”, a conflict of interests (COIs) disclosure requirement, and a specific reference to reporting guidelines, such as CONSORT for RCT.

Results

Among the 87 surgical journals identified, 82 were included in the study: 67 (82%) had explicit instructions for RCT and the remaining 15 (18%) had published at least one RCT. The median impact factor was 2.98 [IQR = 2.48–3.77], and in 2016 and 2017, the journals published a median of 11.5 RCT [IQR = 5–20.75].

The OIA of four journals (5%) stated that the inclusion of a data-sharing statement was mandatory, optional in 45% (n = 37), and not included in 50% (n = 41).

No association was found between journal characteristics and the existence of data-sharing policies (mandatory or optional). A “prospective registration of clinical trials requirement” was associated with International Committee of Medical Journal Editors (ICMJE) allusion or affiliation and higher impact factors.

Journals with specific RCT instructions in their OIA and journals referenced on the ICMJE website more frequently mandated the use of CONSORT guidelines.

Conclusion

Research transparency promotion is still limited in surgical journals. Standardisation of journal requirements according to ICMJE guidelines could be a first step forward for research transparency promotion in surgery.

Authors : Silvia Gianola, Tiago S. Jesus, Silvia Bargeri, Greta Castellini

The COVID-19 pandemic has unleashed a deluge of publications. For this cross-sectional study we compared the amount and reporting characteristics of COVID-19-related academic articles and preprints and the number of ongoing clinical trials and systematic reviews.

To do this, we searched the PubMed database of citations and abstracts for published life science journals by using appropriate combinations of medical subject headings (MeSH terms), and the COVID-19 section of the MedRxiv and BioRxiv archives up to 20 May 2020 (21 weeks).

In addition, we searched Clinicaltrial.gov, Chinese Clinical Trial Registry, EU Clinical Trials Register, and 15 other trial registers, as well as PROSPERO, the international prospective register of systematic reviews.

The characteristics of each publication were extracted. Regression analyses and Z tests were used to detect publication trends and their relative proportions. A total of 3635 academic publications and 3805 preprints were retrieved. Only 8.6% (n = 329) of the preprints were already published in indexed journals. The number of academic and preprint publications increased significantly over time (p<0.001).

Case reports (6% academic vs 0.9% preprints; p<0.001) and letters (17.4% academic vs 0.5% preprints; p<0.001) accounted for a greater share of academic compared to preprint publications. Differently, randomized controlled trials (0.22% vs 0.63%; p<0.001) and systematic reviews (0.08% vs 5%) made up a greater share of the preprints.

The relative proportion of clinical studies registered at Clinicaltrials.gov, Chinese Clinical Trial Registry, and EU Clinical Trials Register was 57.9%, 49.5%, and 98.9%, respectively, most of which were still “recruiting”.

PROSPERO listed 962 systematic review protocols. Preprints were slightly more prevalent than academic articles but both were increasing in number.

The void left by the lack of primary studies was filled by an outpour of immediate opinions (i.e., letters to the editor) published in PubMed-indexed journals. Summarizing, preprints have gained traction as a publishing response to the demand for prompt access to empirical, albeit not peer-reviewed, findings during the present pandemic.

How often do leading biomedical journals use statistical experts to evaluate statistical methods? The results of a survey

Posté le par

Authors : Tom E. Hardwicke, Steven N. Goodman

Scientific claims in biomedical research are typically derived from statistical analyses. However, misuse or misunderstanding of statistical procedures and results permeate the biomedical literature, affecting the validity of those claims.

One approach journals have taken to address this issue is to enlist expert statistical reviewers. How many journals do this, how statistical review is incorporated, and how its value is perceived by editors is of interest.

Here we report an expanded version of a survey conducted more than 20 years ago by Goodman and colleagues (1998) with the intention of characterizing contemporary statistical review policies at leading biomedical journals.

We received eligible responses from 107 of 364 (28%) journals surveyed, across 57 fields, mostly from editors in chief. 34% (36/107) rarely or never use specialized statistical review, 34% (36/107) used it for 10–50% of their articles and 23% used it for all articles.

These numbers have changed little since 1998 in spite of dramatically increased concern about research validity. The vast majority of editors regarded statistical review as having substantial incremental value beyond regular peer review and expressed comparatively little concern about the potential increase in reviewing time, cost, and difficulty identifying suitable statistical reviewers. Improved statistical education of researchers and different ways of employing statistical expertise are needed. Several proposals are discussed.

Disadvantages in preparing and publishing scientific papers caused by the dominance of the English language in science: The case of Colombian researchers in biological sciences

Posté le par

Author : Valeria Ramírez-Castañeda

The success of a scientist depends on their production of scientific papers and the impact factor of the journal in which they publish. Because most major scientific journals are published in English, success is related to publishing in this language.

Currently, 98% of publications in science are written in English, including researchers from English as a Foreign Language (EFL) countries. Colombia is among the countries with the lowest English proficiency in the world. Thus, understanding the disadvantages that Colombians face in publishing is crucial to reducing global inequality in science.

This paper quantifies the disadvantages that result from the language hegemony in scientific publishing by examining the additional costs that communicating in English creates in the production of articles.

It was identified that more than 90% of the scientific articles published by Colombian researchers are in English, and that publishing in a second language creates additional financial costs to Colombian doctoral students and results in problems with reading comprehension, writing ease and time, and anxiety.

Rejection or revision of their articles because of the English grammar was reported by 43.5% of the doctoral students, and 33% elected not to attend international conferences and meetings due to the mandatory use of English in oral presentations.

Finally, among the translation/editing services reviewed, the cost per article is between one-quarter and one-half of a doctoral monthly salary in Colombia. Of particular note, we identified a positive correlation between English proficiency and higher socioeconomic origin of the researcher.

Overall, this study exhibits the negative consequences of hegemony of English that preserves the global gap in science. Although having a common language is important for science communication, generating multilinguistic alternatives would promote diversity while conserving a communication channel. Such an effort should come from different actors and should not fall solely on EFL researchers.
