Entre loi et modèles : variations autour des concepts Zipfiens

Posté le par

Auteurs/Authors : Marc Bertin, Thierry Lafouge

La loi de Zipf s’intéresse aux phénomènes de régularité dans les différents domaines de la connaissance. La régularité mise en exergue ici est celle de la fréquence des mots dans un texte qui s’ancre historiquement autour de l’ingénierie linguistique. Nous présentons les modèles historiques à travers une formalisation mathématique commune afin de mieux appréhender l’intelligibilité des modèles historiques proposés dans la littérature et de discuter de la controverse entre Mandelbrot et Simon.

Nous nous interrogeons sur sa nature et sa résilience à travers une discussion bibliométrique et lexicographique. En s’appuyant sur la position de Kendall, la conclusion positionnera la loi de Zipf par rapport au SHS.

The Twitter accounts of scientific journals: a dataset

Posté le par

Author : Andreas Nishikawa-Pacher

Twitter harbours dense networks of academics, but to what extent do scientific journals use that platform? This article introduces a dataset of 3,485 Twitter accounts pertaining to a sample of 13,821 journals listed in Web of Science’s three major indices (SCIE, SSCI and AHCI).

The summary statistics indicate that 25.2% of the journals have a dedicated Twitter presence. This number is likely to grow, as, on average, every one and a half days sees yet another journal setting up a new profile. The share of Twitter presence, however, varies strongly by publisher and discipline.

The most active discipline is political science, which has almost 75% of its journals on Twitter, while other research categories have zero. The median account issues 116 messages a year and it interacts with distinct other users once in two to three Tweets. Approximately 600 journals refer to themselves as ‘peer-reviewed’, while 263 journals refer to their citation-based impact (like the impact factor) in their profile description.

All in all, the data convey immense heterogeneity with respect to the Twitter behaviour of scientific journals. As there are numerous deceptive Twitter profile names established by predatory publishers, it is recommended that journals establish their official accounts lest bogus journals mislead the public about scientific findings. The dataset is available for use for further scientometric analyses.

Pillars of open science are often included within the editorial policies of scholarly journals, including policies on open access publication, availability of underlying research data, preprints and open peer review.

The aim of this paper is to examine and analyse perceptions and editorial practices related to open access, preprints, open research data and open peer review, from the perspective of editors of scientific journals published in Spain, to gain an insight into editorial policies related to open science.

Results and data were obtained by a combined method of online interviews and an online questionnaire. The online survey was sent to editors from journals indexed in the Dulcinea directory, which at the time of the study included 1875 academic journals. A total of 420 responses (22.4%) were obtained.

The results indicated that 92% of the journals were open access journals, 2% of the journals conducted open peer review, 15% of the journals had instructions to allow archiving preprints, and out of 375 responses, only 59 journals (16%) reported having a policy on underlying research data.

Based on these results, there is a trend in favour of open access, but the perceived barriers to open peer review outweighed the advantages. There is also some reluctance to allow preprints to be made available.

This concern might be because editors want authors and readers to read and cite the contents published in their journals, rather than their preprint versions.

From Research Evaluation to Research Analytics. The digitization of academic performance measurement

Authors : Anne K. Krüger, Sabrina Petersohn

One could think that bibliometric measurement of academic performance has always been digital since the computer-assisted invention of the Science Citation Index. Yet, since the 2000s, the digitization of bibliometric infrastructure has accelerated at a rapid pace. Citation databases are indexing an increasing variety of publication types.

Altmetric data aggregators are producing data on the reception of research outcomes. Machine-readable persistent identifiers are created to unambiguously identify researchers, research organizations, and research objects; and evaluative software tools and current research information systems are constantly enlarging their functionalities to make use of these data and extract meaning from them.

In this article, we analyse how these developments in evaluative bibliometrics have contributed to an extension of indicator-based research evaluation towards data-driven research analytics.

Drawing on empirical material from blogs and websites as well as from research and policy papers, we discuss how interoperability, scalability, and flexibility as material specificities of digital infrastructures generate new ways of data production and their assessment, which affect the possibilities of how academic performance can be understood and (e)valuated.

The Science of Literature Reviews: Searching, Identifying, Selecting, and Synthesising

Authors : Uchendu Eugene Chigbu, Sulaiman Olusegun Atiku, Cherley C. Du Plessis

The ability to conduct an explicit and robust literature review by students, scholars or scientists is critical in producing excellent journal articles, academic theses, academic dissertations or working papers.

A literature review is an evaluation of existing research works on a specific academic topic, theme or subject to identify gaps and propose future research agenda. Many postgraduate students in higher education institutions lack the necessary skills and understanding to conduct in-depth literature reviews.

This may lead to the presentation of incorrect, false or biased inferences in their theses or dissertations. This study offers scientific knowledge on how literature reviews in different fields of study could be conducted to mitigate against biased inferences such as unscientific analogies and baseless recommendations.

The literature review is presented as a process that involves several activities including searching, identifying, reading, summarising, compiling, analysing, interpreting and referencing.

We hope this article serves as reference material to improve the academic rigour in the literature review chapters of postgraduate students’ theses or dissertations. This article prompts established scholars to explore more innovative ways through which scientific literature reviews can be conducted to identify gaps (empirical, knowledge, theoretical, methodological, application and population gap) and propose a future research agenda.

Egocentric cocitation networks and scientific papers destinies

Posté le par

Authors : Béatrice Milard, Yoann Pitarch

To what extent is the destiny of a scientific paper shaped by the cocitation network in which it is involved? What are the social contexts that can explain these structuring? Using bibliometric data, interviews with researchers, and social network analysis, this article proposes a typology based on egocentric cocitation networks that displays a quadruple structuring (before and after publication): polarization, clusterization, atomization, and attrition.

It shows that the academic capital of the authors and the intellectual resources of their research are key factors of these destinies, as are the social relations between the authors concerned.

The circumstances of the publishing are also correlated with the structuring of the egocentric cocitation networks, showing how socially embedded they are. Finally, the article discusses the contribution of these original networks to the analyze of scientific production and its dynamics.

The Role of Metadata and Vocabulary Standards in Enabling Scientific Data Interoperability: A Study of Earth System Science Data Facilities

Posté le par

Authors : Matthew S. Mayernik, Yauheniya Liapich

Objective

Journal publishers within many sciences are increasingly expecting data to be deposited into repositories that support the FAIR principles. Data repositories are thus needing to determine what implications the FAIR principles have on their existing services and systems. Metadata standards and controlled vocabularies are specifically called out as core components of the FAIR principles related to interoperability.

Methods

This paper looks specifically at the ways that metadata standards and controlled vocabularies are used by Earth system science data repositories. Data sets from 55 data facilities were examined to determine which metadata standards and controlled subject / keyword vocabularies were used.

Results

The findings indicate that only the ISO 19115:2003 and DataCite metadata standards are used by more than 40% of the data facilities, and the NASA Global Change Master Directory (GCMD) keywords are the only keyword vocabulary of broad use within this community.

Conclusions

These findings raise questions about the extent to which metadata standards and keyword vocabularies can facilitate interoperability beyond narrow sub-sections of the data facility communities. This study also points to systematic challenges related to migration to new standards.
