A study of the impact of data sharing on article citations using journal policies as a natural experiment

Authors : Garret Christensen, Allan Dafoe, Edward Miguel, Don A. Moore, Andrew K. Rose

This study estimates the effect of data sharing on the citations of academic articles, using journal policies as a natural experiment. We begin by examining 17 high-impact journals that have adopted the requirement that data from published articles be publicly posted.

We match these 17 journals to 13 journals without policy changes and find that empirical articles published just before their change in editorial policy have citation rates with no statistically significant difference from those published shortly after the shift.

We then ask whether this null result stems from poor compliance with data sharing policies, and use the data sharing policy changes as instrumental variables to examine more closely two leading journals in economics and political science with relatively strong enforcement of new data policies.

We find that articles that make their data available receive 97 additional citations (estimate standard error of 34).

We conclude that: a) authors who share data may be rewarded eventually with additional scholarly citations, and b) data-posting policies alone do not increase the impact of articles published in a journal unless those policies are enforced.

Transparent, Reproducible, and Open Science Practices of Published Literature in Dermatology Journals: Cross-Sectional Analysis

Authors : J Michael Anderson, Andrew Niemann, Austin L Johnson, Courtney Cook, Daniel Tritz, Matt Vassar

Background

Reproducible research is a foundational component for scientific advancements, yet little is known regarding the extent of reproducible research within the dermatology literature.

Objective

This study aimed to determine the quality and transparency of the literature in dermatology journals by evaluating for the presence of 8 indicators of reproducible and transparent research practices.

Methods

By implementing a cross-sectional study design, we conducted an advanced search of publications in dermatology journals from the National Library of Medicine catalog. Our search included articles published between January 1, 2014, and December 31, 2018.

After generating a list of eligible dermatology publications, we then searched for full text PDF versions by using Open Access Button, Google Scholar, and PubMed. Publications were analyzed for 8 indicators of reproducibility and transparency—availability of materials, data, analysis scripts, protocol, preregistration, conflict of interest statement, funding statement, and open access—using a pilot-tested Google Form.

Results

After exclusion, 127 studies with empirical data were included in our analysis. Certain indicators were more poorly reported than others. We found that most publications (113, 88.9%) did not provide unmodified, raw data used to make computations, 124 (97.6%) failed to make the complete protocol available, and 126 (99.2%) did not include step-by-step analysis scripts.

Conclusions

Our sample of studies published in dermatology journals do not appear to include sufficient detail to be accurately and successfully reproduced in their entirety. Solutions to increase the quality, reproducibility, and transparency of dermatology research are warranted.

More robust reporting of key methodological details, open data sharing, and stricter standards journals impose on authors regarding disclosure of study materials might help to better the climate of reproducible research in dermatology.

Inferring the causal effect of journals on citations

Author : Vincent Traag

Articles in high-impact journals are by definition more highly cited on average. But are they cited more often because the articles are somehow « better »? Or are they cited more often simply because they appeared in a high-impact journal? Although some evidence suggests the latter the causal relationship is not clear.

We here compare citations of published journal articles to citations of their preprint versions to uncover the causal mechanism. We build on an earlier model to infer the causal effect of journals on citations. We find evidence for both effects.

We show that high-impact journals seem to select articles that tend to attract more citations. At the same time, we find that high-impact journals augment the citation rate of published articles.

Our results yield a deeper understanding of the role of journals in the research system. The use of journal metrics in research evaluation has been increasingly criticised in recent years and article-level citations are sometimes suggested as an alternative.

Our results show that removing impact factors from evaluation does not negate the influence of journals. This insight has important implications for changing practices of research evaluation.

The Pricing of Open Access Journals: Diverse Niches and Sources of Value in Academic Publishing

Authors : Kyle Siler, Koen Frenken

Open Access (OA) publishing has created new academic and economic niches in contemporary science. OA journals offer numerous publication outlets with varying editorial philosophies and business models.

This article analyzes the Directory of Open Access Journals (DOAJ) (N=12,127) to identify characteristics of OA academic journals related to the adoption of Article Processing Charge (APC)-based business models, as well as price points of journals that charge APCs. Journal Impact Factor (JIF), language, publisher mission, DOAJ Seal, economic and geographic regions of publishers, peer review duration and journal discipline are all significantly related to the adoption and pricing of journal APCs.

Even after accounting for other journal characteristics (prestige, discipline, publisher country), journals published by for-profit publishers charge the highest APCs. Journals with status endowments (JIF, DOAJ Seal), articles written in English, published in wealthier regions, and in medical or science-based disciplines are also relatively costlier.

The OA publishing market reveals insights into forces that create economic and academic value in contemporary science. Political and institutional inequalities manifest in the varying niches occupied by different OA journals and publishers.

Adoption of the open access business model in scientific journal publishing – A cross-disciplinary study

Authors : Bo-Christer Björk, Timo Korkeamäki

Scientific journal publishers have over the past twenty-five years rapidly converted to predominantly electronic dissemination, but the reader-pays business model continues to dominate the market.

Open Access (OA) publishing, where the articles are freely readable on the net, has slowly increased its market share to near 20%, but has failed to fulfill the visions of rapid proliferation predicted by many early proponents.

The growth of OA has also been very uneven across fields of science. We report market shares of open access in eighteen Scopus-indexed disciplines ranging from 27% (agriculture) to 7% (business).

The differences become far more pronounced for journals published in the four countries, which dominate commercial scholarly publishing (US, UK, Germany and the Netherlands). We present contrasting developments within six academic disciplines.

Availability of funding to pay publication charges, pressure from research funding agencies, and the diversity of discipline-specific research communication cultures arise as potential explanations for the observed differences.

Grey Literature: Use, Creation, and Citation Habits of Faculty Researchers across Disciplines

Authors : Kristen Cooper, Wanda Marsolek, Amy Riegelman, Shannon Farrell, Julie Kelly

INTRODUCTION

Grey literature is ephemeral, and the level to which it is created, used, and cited by faculty, graduate students, and other researchers is not well understood.

METHODS

This electronic survey was distributed to a sample (57%) of the faculty across a wide variety of disciplines with the only criteria based on tenure and tenure-track faculty at the University of Minnesota Twin Cities, a large R1 institution.

RESULTS

Faculty across disciplines both use and create grey literature for several reasons, including its far more rapid Faculty across disciplines both use and create grey literature for several reasons, including its far more rapid publication process.

DISCUSSION

Many faculty in a wide variety of disciplines are using and creating grey literature. The survey illustrates the different types of grey literature that are being used and for what purpose.

Other topics, such as how faculty are finding grey literature (via Google Scholar and professional contacts), whether they are citing it, and which types they create (e.g., conference papers, preprints, technical reports) are also discussed.

CONCLUSION

As a result of this survey, librarians can provide support for faculty who use and create grey literature in all disciplines and advocate for and promote grey literature to faculty. With more scholars participating in systematic reviews of grey literature, librarians will need to be more cognizant of where and how it may be discovered.

The Common Ground of Open Access and Interdisciplinarity

Author : Patrick Gamsby

In recent years, Open Access and interdisciplinarity have emerged as two prevalent trends in academia. Although seemingly separate pursuits with separate literature, goals, and advocates, there are significant interconnections between these two movements that have largely gone unnoticed.

This paper provides a philosophical inquiry into the unexplored relationship between these two trends and makes the case that there is an intrinsic affinity between Open Access and interdisciplinarity and, as such, concludes that all interdisciplinary research, to remain true to the foundational tenets of interdisciplinarity, ought to be Open Access.
