The website Sci-Hub provides access to scholarly literature via full text PDF downloads. The site enables users to access articles that would otherwise be paywalled. Since its creation in 2011, Sci-Hub has grown rapidly in popularity.

However, until now, the extent of Sci-Hub’s coverage was unclear. As of March 2017, we find that Sci-Hub’s database contains 68.9% of all 81.6 million scholarly articles, which rises to 85.2% for those published in closed access journals.

Furthermore, Sci-Hub contains 77.0% of the 5.2 million articles published by inactive journals. Coverage varies by discipline, with 92.8% coverage of articles in chemistry journals compared to 76.3% for computer science.

Coverage also varies by publisher, with the coverage of the largest publisher, Elsevier, at 97.3%. Our interactive browser at greenelab.github.io/scihub allows users to explore these findings in more detail.

Finally, we estimate that over a six month period in 2015–2016, Sci-Hub provided access for 99.3% of valid incoming requests. Hence, the scope of this resource suggests the subscription publishing model is becoming unsustainable. For the first time, the overwhelming majority of scholarly literature is available gratis to anyone.

Medical Theses and Derivative Articles: Dissemination Of Contents and Publication Patterns

Authors : Mercedes Echeverria, David Stuart, Tobias Blanke

Doctoral theses are an important source of publication in universities, although little research has been carried out on the publications resulting from theses, on so-called derivative articles.

This study investigates how derivative articles can be identified through a text analysis based on the full-text of a set of medical theses and the full-text of articles, with which they shared authorship.

The text similarity analysis methodology applied consisted in exploiting the full-text articles according to organization of scientific discourse (IMRaD) using the TurnItIn plagiarism tool.

The study found that the text similarity rate in the Discussion section can be used to discriminate derivative articles from non-derivative articles.

Additional findings were: the first position of the thesis’s author dominated in 85% of derivative articles, the participation of supervisors as coauthors occurred in 100% of derivative articles, the authorship credit retained by the thesis’s author was 42% in derivative articles, the number of coauthors by article was 5 in derivative articles versus 6.4 coauthors, as average, in non-derivative articles and the time differential regarding the year of thesis completion showed that 87.5% of derivative articles were published before or in the same year of thesis completion.

Scientist impact factor (SIF): a new metric for improving scientists’ evaluation?

Posté le par

Authors : Giuseppe Lippi, Camilla Mattiuzzi

Background

The publication of scientific research is the mainstay for knowledge dissemination, but is also an essential criterion of scientists’ evaluation for recruiting funds and career progression.

Although the most widespread approach for evaluating scientists is currently based on the H-index, the total impact factor (IF) and the overall number of citations, these metrics are plagued by some well-known drawbacks. Therefore, with the aim to improve the process of scientists’ evaluation, we developed a new and potentially useful indicator of recent scientific output.

Methods

The new metric scientist impact factor (SIF) was calculated as all citations of articles published in the two years following the publication year of the articles, divided by the overall number of articles published in that year. The metrics was then tested by analyzing data of the 40 top scientists of the local University.

Results

No correlation was found between SIF and H-index (r=0.15; P=0.367) or 2 years H-index (r=−0.01; P=0.933), whereas the H-Index and 2 years H-index values were found to be highly correlated (r=0.57; P<0.001). A highly significant correlation was also observed between the articles published in one year and the total number of citations to these articles in the two following years (r=0.62; P<0.001).

Conclusions

According to our data, the SIF may be a useful measure to complement current metrics for evaluating scientific output. Its use may be especially helpful for young scientists, wherein the SIF reflects the scientific output over the past two years thus increasing their chances to apply to and obtain competitive funding.

The changing role of research publishing: a case study from Springer Nature

Posté le par

Author : Steven Inchcoombe

Using Springer Nature as a case study this article explores the future of research publishing, with the guiding objective of identifying how such organizations can better serve the needs of researchers and those that support researchers (particularly academic institutions, institutional libraries, research funding bodies and academic societies) as we work together to help advance discovery for the benefit of all.

Progress in four key areas is described: improving the publishing process, innovating across science communication, driving the growth and development of open research and adding value beyond publishing.

The aim of this article is thus to set out a clear vision of what research publishers can achieve if they especially focus on addressing researchers’ needs and apply their considerable resources and expertise accordingly.

If delivered with care, this vision should enable research publishers to help advance discovery, publish more robust and insightful research, support the development of new areas of knowledge and understanding, and make these ideas and this information accessible, usable and reusable by humans and machines alike.

Journal of Open Source Software (JOSS): design and first-year review

Posté le par

Authors : Arfon M Smith, Kyle E Niemeyer, Daniel S Katz, Lorena A Barba, George Githinji, Melissa Gymrek, Kathryn D Huff, Christopher R Madan, Abigail Cabunoc Mayes, Kevin M Moerman, Pjotr Prins, Karthik Ram, Ariel Rokem, Tracy K Teal, Roman Valls Guimera, Jacob T Vanderplas

This article describes the motivation, design, and progress of the Journal of Open Source Software (JOSS). JOSS is a free and open-access journal that publishes articles describing research software. It has the dual goals of improving the quality of the software submitted and providing a mechanism for research software developers to receive credit.

While designed to work within the current merit system of science, JOSS addresses the dearth of rewards for key contributions to science made in the form of software. JOSS publishes articles that encapsulate scholarship contained in the software itself, and its rigorous peer review targets the software components: functionality, documentation, tests, continuous integration, and the license.

A JOSS article contains an abstract describing the purpose and functionality of the software, references, and a link to the software archive. The article is the entry point of a JOSS submission, which encompasses the full set of software artifacts.

Submission and review proceed in the open, on GitHub. Editors, reviewers, and authors work collaboratively and openly. Unlike other journals, JOSS does not reject articles requiring major revision; while not yet accepted, articles remain visible and under review until the authors make adequate changes (or withdraw, if unable to meet requirements).

Once an article is accepted, JOSS gives it a DOI, deposits its metadata in Crossref, and the article can begin collecting citations on indexers like Google Scholar and other services. Authors retain copyright of their JOSS article, releasing it under a Creative Commons Attribution 4.0 International License.

In its first year, starting in May 2016, JOSS published 111 articles, with more than 40 additional articles currently under review. JOSS is a sponsored project of the nonprofit organization NumFOCUS and is an affiliate of the Open Source Initiative.

Posté le par

Authors : Wei Quan, Bikun Chen, Fei Shu

Purpose

The purpose of this study is to present the landscape of the cash-per-publication reward policy in China and reveal its trend since the late 1990s.

Design/methodology/approach

This study is based on the analysis of 168 university documents regarding the cash-per-publication reward policy at 100 Chinese universities.

Findings

Chinese universities offer cash rewards from 30 to 165,000 USD for papers published in journals indexed by Web of Science (WoS), and the average reward amount has been increasing for the past 10 years.

Originality/value

The cash-per-publication reward policy in China has never been systematically studied and investigated before except for in some case studies. This is the first paper that reveals the landscape of the cash-per-publication reward policy in China.

Open Access and Promotion and Tenure Evaluation Plans at the University of Wisconsin–Eau Claire

Posté le par

Authors : Stephanie H. Wical, Gregory J. Kocken

Department and program evaluation plans at the University of Wisconsin–Eau Claire were examined to see if these documents provide evidence that could be used to justify supporting the publication of peer-reviewed open access articles toward tenure and promotion.

In an earlier study, the authors reveal that faculty members at the University of Wisconsin–Eau Claire are more unaware of open access publishing than their counterparts at larger universities.

These findings dovetail with other studies that show that faculty members are reluctant to publish in open access journals because of concerns about the quality of those journals. The existing body of scholarship suggests that tenure-line faculty fear publishing in open access journals because it could adversely impact their chances of promotion and tenure.

The authors of this current study sought to determine if department and program evaluation plans could influence negative perceptions faculty have of open access journals. The implications of this study for librarians, scholarly communication professionals, tenure-line faculty, departments, and programs are addressed.
