Google Scholar, Scopus and the Web of Science: a longitudinal and cross-disciplinary comparison

Scientometric analysis of vital pulp therapy studies

AIM

To present a scientometric analysis of the entire body of scientific publications in the field of vital pulp therapy (VPT) and analyse the research trends and popular topics.

METHODOLOGY

A comprehensive literature search was conducted in the Web of Science and Scopus databases on 21 August 2020 to identify all articles related to VPT. The publications were reviewed and basic research parameters were collected, including publication year, patterns of authorship, geographical distribution of scientific productions, journals, h-index, study design and keyword analysis. Web of Science, Scopus and Google Scholar databases were used for the citation analysis of the ten top cited articles. The data were analysed using VOSviewer and visualized by tables and diagrams.

RESULTS

In total, 1197 VPT-associated items were identified from 64 countries in 176 journals. The majority of papers were published in the Journal of Endodontics. The United States of America was the leading country for number of publications, citations, h-index and collaborations. The distribution of articles based on study design was as follows: basic science (35%), clinical (27%), observational studies (26%) and review publications (12%). The most frequently occurring keywords were pulpotomy, mineral trioxide aggregate, calcium hydroxide and direct pulp capping.

CONCLUSIONS

This scientometric analysis outlines the evolutionary trends and the productivity of researchers and countries in the field of vital pulp therapy. Research output is dominated by basic science articles involving innovative materials published in high impact factor dental journals.

OhioLINK librarians and Google Scholar over time: a longitudinal analysis of attitudes and uses

Purpose

This study aims to focus on how librarians use and promote Google Scholar (GS) within their library instruction sessions. This study also examines how Google Scholar and the Google Scholar discovery layer, library links, is promoted on library websites. This information is then analyzed across the three date ranges.

Design/methodology/approach

This study provides a longitudinal analysis of the opinions and uses of Google Scholar by the Ohio consortium of libraries, OhioLINK. This study uses survey data that was collected in 2007, 2014 and 2019 via the OhioLINK Listserv and builds off of co-author’s previous study (2008), which examined the attitudes of OhioLINK librarians as it related to Google Scholar.

Findings

The results of this research suggested that there were significant changes in use and opinions of Google Scholar between 2007 and 2014 with more normalization of uses and opinions occurring between 2014 and 2019.

Research limitations/implications

Respondents were not asked for the type of library where they work or to identify their position within their libraries, which necessarily limits the conclusions that can be drawn from the survey responses. In retrospect, limiting the sample to instruction librarians or faculty librarians might have yielded more meaningful results. Additionally, this project did not evaluate the uses and opinions of librarians using GS at the reference desk. By providing this information, it would be easier to truly glean the uses and opinions of librarians with regard to GS.

Practical implications

This research will assist librarians contextualize how one of the most popular research resources has been used and promoted by those within the field and how those opinions have changed over time. This study will provide context into how Google Scholar became one of the most popular research tools and how attitudes of this unprecedented, and controversial, resource came to be accepted by librarians over the past 15 years.

Social implications

This study will help librarians better contextualize how other librarians use and promote Google Scholar. Furthermore, it demonstrates how a controversial information research tool became accepted by those in the field over time.

Originality/value

According to the authors’ knowledge, this research is the only study to provide a longitudinal analysis of the librarian opinions of Google Scholar. It targeted the same audience in identical surveys in a way no other Google Scholar research has done. It builds off of the co-author’s (2008) work, which is a well-cited study regarding librarian attitudes of Google Scholar. This research was done on the 15th year anniversary of Google Scholar.

[Thirty years of research in suicidology in France: A bibliometric study]

OBJECTIVES

To study the quantitative evolution of research in suicidology in France for 30 years.

METHODS

Analysis of the Web of Science database; identification of publications between 1989 and 2018 with at least one author with an affiliation in France and focusing on suicidal behavior and self-inflicted acts.

RESULTS

In total, 1188 publications were identified. Over 30 years, the number of publications has been multiplied by 8.8 (particularly since 2005), a growth higher than those published in psychiatry and science in France, and in suicidology worldwide. France has contributed 3.3% of global publications since 2014 (ranks 8th in the world, recently outnumbered by South Korea and China) and 10.6% of European publications (ranks 3rd after the United Kingdom and Germany). The number of international co-publications has risen sharply over the last 30 years (44.9% between 2014 and 2018), notably with the USA, Canada and Spain. Use of English has increased from 37 to 78% of publications. Inserm, and the Universities and Academic hospitals of Paris and Montpellier are among the first institutions in terms of number of publications. Twenty-one of the 30 most published authors are men. The mention of the origin of the financing of the publications is increasing but remains limited.

CONCLUSION

Suicidology has been a dynamic field of research in France for the last fifteen years, with a growing international visibility, but there is also room for improvement. An effort remains to be made to improve women's place in these publications.

THE PROFILE OF THE ACADEMIC PRODUCTION ON MEN’S ARTISTIC GYMNASTICS FROM THE WEB OF SCIENCE AND SCOPUS

The objective of this study was to describe the scientific production on men’s artistic gymnastics (MAG) in journals indexed on the Scopus and Web of Science platforms. To this end, we searched on both platforms for the keywords “men’s artistic gymnastics” and "male artistic gymnastics", with a non-specified date range. After applying the exclusion criteria, 52 scientific articles were found, distributed between 1994 and 2019. The year with the highest number of publications so far is 2018, with emphasis on the period between 2014 and 2018. The authors who contributed the most were Maurice Yeadon and Michael Hiley (both from British universities), Marco Bortoleto (from Brazil), and Ivan Čuk (from Slovenia). There is a predominance of MAG-related articles in the Science of Gymnastics Journal (21%), followed by the Journal of Biomechanics (7%). The articles deal with the biomechanics of gymnastics (34%), the rules of the sport and its judging (19%), the social, historical and political aspects of gymnastics (14%), morphological characteristics of athletes (10%), athletes’ health (10%), gymnastics training aspects (8%), and finally, analyses of athletes’ age over the years (6%).

Research Trends in Geotourism: A Bibliometric Analysis Using the Scopus Database

Geodiversity has elements of exceptional scientific value that are considered to represent geoheritage, or geological heritage. One way to conserve and promote the knowledge of these elements is through the initiatives of United Nations Educational, Scientific, and Cultural Organization (UNESCO) Global Geoparks, which, over a decade ago, began to notably highlight a new sustainable tourism alternative called geotourism, or geological tourism, that promotes the protection of the unique geological resources of territory and, at the same time, provides social, economic, and environmental benefits. This study aims to investigate the scientific information related to geotourism in the Scopus database through a bibliometric analysis, using the VOSviewer software, for the evaluation of the structure, conceptual evolution, and trends of geotourism following related publications. The research comprises four study phases: (i) search criteria of the research field; (ii) search and selection of documents; (iii) software and data extraction; and (iv) analysis of results and trends. The results present geotourism as a scientific discipline that is in a phase of exponential research growth and exhibits its scientific productivity from 1984 to 2019, where three main periods are differentiated: introduction, theoretical development, and diversification of information. The most active research area is geomorphological heritage, which is very far from the emerging line of research of engineering geology in geotourism. However, growing exploration during the last six years has generated the development of various geoscientific branches promoted by geotourism that, currently, present their research area trends such as geosites, geoheritages, and geoparks.

Google Scholar, Microsoft Academic, Scopus, Dimensions, Web of Science, and OpenCitations' COCI: a multidisciplinary comparison of coverage via citations

New sources of citation data have recently become available, such as Microsoft Academic, Dimensions, and the OpenCitations Index of CrossRef open DOI-to-DOI citations (COCI). Although these have been compared to the Web of Science Core Collection (WoS), Scopus, or Google Scholar, there is no systematic evidence of their differences across subject categories. In response, this paper investigates 3,073,351 citations found by these six data sources to 2,515 English-language highly-cited documents published in 2006 from 252 subject categories, expanding and updating the largest previous study. Google Scholar found 88% of all citations, many of which were not found by the other sources, and nearly all citations found by the remaining sources (89–94%). A similar pattern held within most subject categories. Microsoft Academic is the second largest overall (60% of all citations), including 82% of Scopus citations and 86% of WoS citations. In most categories, Microsoft Academic found more citations than Scopus and WoS (182 and 223 subject categories, respectively), but had coverage gaps in some areas, such as Physics and some Humanities categories. After Scopus, Dimensions is fourth largest (54% of all citations), including 84% of Scopus citations and 88% of WoS citations. It found more citations than Scopus in 36 categories, more than WoS in 185, and displays some coverage gaps, especially in the Humanities. Following WoS, COCI is the smallest, with 28% of all citations. Google Scholar is still the most comprehensive source. In many subject categories Microsoft Academic and Dimensions are good alternatives to Scopus and WoS in terms of coverage.

Should Google Scholar be used for benchmarking against the professoriate in education?

In the neoliberal environment of contemporary academia, an individual’s research rankings and outputs can shape their career security and progression. When applying for ongoing employment and promotional opportunities, academics may benchmark their performance against that of superior colleagues to demonstrate their performance in relation to their discipline. The H-index and citation rates are commonly used to quantify the value of an academic’s work, and they can be used comparatively for benchmarking purposes. The focus of this paper is to critically consider if Google Scholar be used for benchmarking against the professoriate in education, by weighting up issues of data reliability and participation. The Google Scholar profiles of full professors at top ranked universities in Australia, the United Kingdom and the United States of America are analysed to explore how widespread Google Scholar use is in the education professoriate. Quartiles of impact are established in relation to H-index, with exploration of how gender is distributed across these quartiles. Limitations of using Google Scholar data are highlighted through a taxonomy of quality confounders, and the utility of Google Scholar as a legitimate tool for benchmarking against the professoriate in education is strongly challenged. As metrics continue to rise in their importance for academics’ job security and promotional prospects, reliance on metrics of dubious quality and uneven participation must be questioned.

Performance Analysis and Science Mapping of Institutional Entrepreneurship Research

Institutional entrepreneurship comprises the activities of agents who disrupt existing social institutions or create new ones, often to enable diffusion, especially of radical innovations, in a market. The increased interest in institutional entrepreneurship has produced a large number of scholarly publications, especially in the last five years. As a consequence, the literature landscape is somewhat complex and scattered. We aim to compile a quantitative overview of the field within business and management research by conducting bibliometric performance analyses and science mappings. We identified the most productive and influential journals, authors, and articles with the highest impact. We found that institutional entrepreneurship has stronger ties to organization studies than to entrepreneurship research. Additionally, a large body of literature at the intersection of institutions and entrepreneurship does not refer to institutional entrepreneurship theory. The science mappings revealed a distinction between theoretical and conceptual research on one hand and applied and empirical research on the other hand. Research clusters reflect the structure–agency problem by focusing on the change agent’s goals and interests, strategies, and specific implementation mechanisms, as well as the relevance of public agents for existing institutions, and a more abstract process rather than agency view.

Bibliometric Analysis of Ebola Research Indexed in Web of Science and Scopus (2010-2020)

Background

Within the past decade, Africa has faced several recurrent outbreaks of Ebola virus disease (EVD), including the 2014-2016 outbreak in West Africa and the recent 2018-2020 Kivu outbreak in the Democratic Republic of Congo. The study thus aimed at quantifying and mapping the scientific output of EVD research published within 2010-2020 though a bibliometric perspective.

Methods

EVD-related publications from 2010 to 2020 were retrieved from the Web of Science (WoS) and Scopus databases by using the keywords ‘Ebola', ‘Ebola Virus Disease', ‘Ebolas', and ‘ebolavirus'. Biblioshiny software (using R-studio cloud) was used to categorise and evaluate authors', countries' and journals' contribution. VOSviewer was used for network visualisation.

Results

According to the used search strategy, a total of 3865 and 3848 EVD documents were published in WoS and Scopus, respectively. The average citation per document was 16.1 (WoS) and 16.3 (Scopus). The results show an overall increase in the publication trend within the study period. The leading countries in EVD research were the USA and UK, with over 100 papers in both databases, including Nigeria and South Africa. NIAID and CDC-USA were the most influential institutions, while “Infectious Diseases” and “Medicine” were the most decisive research fields. The most contributing authors included Feldmann H and Qiu XG with over 60 papers in each database, while Journal of Infectious Diseases was the most crucial journal. The most cited article was from Aylward et al. published in 2014, while recent years displayed a keyword focus on “double-blind”, “efficacy”, “ring vaccination” and “drug effect”.

Conclusion

This bibliometric analysis provides an updated historical perspective of progress in EVD research and has highlighted the role played by various stakeholders. However, the contribution of African countries and institutions is not sufficiently reflected, implying a need for increased funding and focus on EVD research for effective prevention and control.

Climate Change: A Bibliometric Study of Adaptation, Mitigation and Resilience

The paper uses bibliometric methods to explore the production of knowledge in the field of climate change from 1991–2019. Using the Web of Science database, we demonstrate the growth of publications in the field, including papers in mitigation, adaptation and resilience. Using VOSviewer software, we show the connections between these subfields and the journals in which they are published. The analysis displays clusters of publications in different subfields and minimal convergence of research in STEM fields and the social sciences. We suggest that this lack of convergence may reflect a relative shortage of interdisciplinary research which may in turn have negative outcomes in terms of research and policy.

All downhill from the PhD? The typical impact trajectory of U.S. academic careers

Within academia, mature researchers tend to be more senior, but do they also tend to write higher impact articles? This article assesses long-term publishing (16+ years) United States (U.S.) researchers, contrasting them with shorter-term publishing researchers (1, 6, or 10 years). A long-term U.S. researcher is operationalized as having a first Scopus-indexed journal article in exactly 2001 and one in 2016–2019, with U.S. main affiliations in their first and last articles. Researchers publishing in large teams (11+ authors) were excluded. The average field and year normalized citation impact of long- and shorter-term U.S. researchers’ journal articles decreases over time relative to the national average, with especially large falls for the last articles published, which may be at least partly due to a decline in self-citations. In many cases researchers start by publishing above U.S. average citation impact research and end by publishing below U.S. average citation impact research. Thus, research managers should not assume that senior researchers will usually write the highest impact papers.

A Discrimination Index Based on Jain's Fairness Index to Differentiate Researchers with Identical H-index Values

Purpose

This paper proposes a discrimination index method based on the Jain's fairness index to distinguish researchers with the same H-index.

Design/methodology/approach

A validity test is used to measure the correlation of D-offset with the parameters, i.e. H-index, the number of cited papers, the total number of citations, the number of indexed papers, and the number of uncited papers. The correlation test is based on the Saphiro-Wilk method and Pearson's product-moment correlation.

Findings

The result from the discrimination index calculation is a two-digit decimal value called the discrimination-offset (D-offset), with a range of D-offset from 0.00 to 0.99. The result of the correlation value between the D-offset and the number of uncited papers is 0.35, D-offset with the number of indexed papers is 0.24, and the number of cited papers is 0.27. The test provides the result that it is very unlikely that there exists no relationship between the parameters.

Practical implications

For this reason, D-offset is proposed as an additional parameter for H-index to differentiate researchers with the same H-index. The H-index for researchers can be written with the format of “H-index: D-offset”.

Originality/value

D-offset is worthy to be considered as a complement value to add the H-index value. If the D-offset is added in the H-index value, the H-index will have more discrimination power to differentiate the rank of the researchers who have the same H-index.

Sustainability Assessment and Engineering of Emerging Aircraft Technologies—Challenges, Methods and Tools

Driven by concerns regarding the sustainability of aviation and the continued growth of air traffic, increasing interest is given to emerging aircraft technologies. Although new technologies, such as battery-electric propulsion systems, have the potential to minimise in-flight emissions and noise, environmental burdens are possibly shifted to other stages of the aircraft’s life cycle, and new socio-economic challenges may arise. Therefore, a life-cycle-oriented sustainability assessment is required to identify these hotspots and problem shifts and to derive recommendations for action for aircraft development at an early stage. This paper proposes a framework for the modelling and assessment of future aircraft technologies and provides an overview of the challenges and available methods and tools in this field. A structured search and screening process is used to determine which aspects of the proposed framework are already addressed in the scientific literature and in which areas research is still needed. For this purpose, a total of 66 related articles are identified and systematically analysed. Firstly, an overview of statistics of papers dealing with life-cycle-oriented analysis of conventional and emerging aircraft propulsion systems is given, classifying them according to the technologies considered, the sustainability dimensions and indicators investigated, and the assessment methods applied. Secondly, a detailed analysis of the articles is conducted to derive answers to the defined research questions. It illustrates that the assessment of environmental aspects of alternative fuels is a dominating research theme, while novel approaches that integrate socio-economic aspects and broaden the scope to battery-powered, fuel-cell-based, or hybrid-electric aircraft are emerging. It also provides insights by what extent future aviation technologies can contribute to more sustainable and energy-efficient aviation. The findings underline the need to harmonise existing methods into an integrated modelling and assessment approach that considers the specifics of upcoming technological developments in aviation.

Digitally-enabled sustainable supply chains in the 21st century: A review and a research agenda

While the potential benefits of integrating digital technologies and supply chain management have been widely reported, less is known concerning the current state-of-the-art literature on big data-driven sustainable supply chains. Therefore, this study aims to systematise published studies which address the implications of big data for sustainable supply chain management. Through a systematic literature review, this work makes three significant contributions: (a) it provides an overview of extant literature on this topic in recent years; (b) it proposes seven gaps in the literature in order to foster future investigations on big data-driven sustainable supply chains; (c) it offers four lessons for business practitioners aiming to use big data for sustainable supply chain practices. These lessons suggest that: developing big data analytics capability has to become a business priority in order to effectively build competitive sustainable supply chains; big data has benefits for each of the dimensions of the triple-bottom-line in supply chains; the implementation of big data for sustainability in supply chains presents some challenges for firms; the development of complementary organizational capabilities is needed to overcome challenges and facilitate the benefits of big data technology for sustainable supply chain management.

The Way Forward in Mindfulness and Sustainability: a Critical Review and Research Agenda

The ecological crisis demands new strategies to rapidly transform our society into a more sustainable one. A growing amount of research points towards the potential of mindfulness to help transform people’s motivations for sustainability. This article reviews 30 years of research in mindfulness and sustainability and disentangles theoretical knowledge from empirical evidence. We identified six leading theoretical links between mindfulness and sustainability which find backing in empirical work: reduced automaticity, enhanced health and subjective well-being, greater connectedness with nature, improved pro-sociality, recognition of intrinsic values and openness to new experiences. Many of the studies involve considerable methodological caveats, most importantly a lack of mindfulness practice indicators and environmental impact measures. To reach the point where policy makers could embrace mindfulness-based policies to promote societal well-being and sustainability, the research must go beyond the present focus on correlative research. The proof of causality posits the greatest challenge for the next decade of research. Inspired by principles from policy evaluation, we propose a research agenda that offers direction for collaborative efforts and innovative interdisciplinary study designs in a logical model: (how) does the practice of mindfulness contribute to individual behaviour change and (how) does this individual change translate into societal change?

Measuring Productivity and Impact of Veterinary Education-Related Research at the Institutional and Individual Levels Using the H-Index

The natural progression of observation through inquiry to scholarship that is common to scientists is not well demonstrated among veterinary educators. One possible institutional barrier to promotion of education-related research among faculty is lack of a mechanism to demonstrate productivity and impact of scholarship of teaching and learning (SoTL) and hypothesis-driven research related to education. The h-index is one measure of research productivity. The h-index was calculated for individuals at one veterinary college and was compared between select North American schools of veterinary medicine to demonstrate baseline values for this kind of scholarship in this discipline. Use of standard search techniques using Google Scholar for citation count generated a slightly lower score than a more labor-intensive search and review of curricula vitae. The h-index across institutions ranged from 1 to 11, with a mean score of 6.0 (SD = 2.8). Five hundred forty-four education-related articles were published in 45 different journals; the primary sites of publication were the Journal of Veterinary Medical Education (JVME) and the Journal of the American Veterinary Medical Association.

The impact of illness identity on recovery from severe mental illness: A review of the evidence

The "Illness Identity" model proposed that self-stigma impacts hope and self-esteem and subsequently leads to a cascade of negative effects on outcomes related to recovery among people diagnosed with severe mental illnesses. The purpose of the present review is to take stock of research support for the model. The citation index SCOPUS was reviewed for all papers published in peer-reviewed journals in English between 2010 and 2019 citing one of the initial 3 articles discussing the model: 111 studies met inclusion criteria and were reviewed. The most frequently tested, and supported, aspects of the model were relationships between self-stigma and self-esteem, hope, psychiatric symptoms and social relationships. Least frequently studied areas were relationships with suicide, avoidant coping, treatment adherence and vocational functioning, although they were supported in the majority of studies. The "insight paradox" was also tested in a relatively small number of studies, with mixed results. Findings were robust to geographic location of study, method, and subpopulation studied. Findings indicate that a large body of research has tested, and largely supported, the various components of the Illness Identity model, although some components need further investigation and there is a need for more comprehensive tests of the model.

Mapping Research on Sustainable Supply-Chain Management

The aim of the paper is to map the thematic landscape of the sustainable supply-chain management (SSCM) research field and contribute to exploring “relationships among specific constructs” in the field. The use of bibliometric methodology and the focus given to relationships among topics categorized into thematic clusters within the field are the features which differ the study from other reviews in the research field. The operational objectives of the study are as follows: (1) to profile the development of the SSCM research field and its scientific output, (2) to identify leading thematic areas in the field and explore their composition and relationships among them, (3) to identify ‘hot’, emerging topics in the field. The analysis of change in the number of publications and citations related to the SSCM concept supports the study of research productivity in the field. General publication profiling focuses on the identification of subject areas and leading contributors to the research field, i.e., countries, research institutions, source titles and authors. Keywords co-occurrence analysis is employed to identify and explore leading and emerging topics. The study points out that the main thematic areas in the SSCM research field are: (1) economy and management in the context of the environment, (2) supply chain in the context of sustainability, (3) sustainable supply chains—process approach, (4) decision making for SSCM, (5) the practice context of supply-chain management, and (6) competition and social responsibility (SR) issues. The most up-to-date topics of scientific inquiry in the field focus around the following issues: (1) human aspects, (2) sustainable supplier selection, (3) manufacturing, (4) circular economy, (5) efficiency, (6) sustainable practices, (7) commerce, (8) costs, (9) environmental impact, and (10) the textile industry.

Interorganizational learning: a bibliometric review and research agenda

Purpose

Scholarly interest in interorganizational learning (IOL) has spiked in the past decade because of its potential to absorb, transfer and create valuable knowledge for enhanced innovative performance and sustained competitive advantage. However, only a handful of review studies exists on the topic. The evolution of IOL has not been studied explicitly and there is a lack of understanding of the field trends. To fill this gap, this paper aims to comprehensively review the literature on IOL and map its evolution and trends using bibliometric techniques. In particular, the authors use visualization of science mapping freeware to systematize the findings and interpret the results.

Design/methodology/approach

The authors synthesize the findings using “evaluative bibliometric techniques” to identify the quality and quantity indicators of the IOL research and use “relational bibliometric techniques” to determine the structural indicators of the IOL field such as the intellectual foundations and emerging research themes of IOL research.

Findings

Through an analysis of 208 journal publications obtained from the Scopus database, the authors determine the leading authors, countries, highly cited papers and their contributions to the IOL literature. By identifying the key hotspots, intellectual foundations and emerging trends of IOL, the authors provide promising avenues in IOL research.

Originality/value

To the best of the knowledge, this study is the first to systematically review the IOL literature and provide future research directions.

Three Commonly Utilized Scholarly Databases and a Social Network Site Provide Different, But Related, Metrics of Pharmacy Faculty Publication

Scholarly productivity is a critical component of pharmacy faculty effort and is used for promotion and tenure decisions. Several databases are available to measure scholarly productivity; however, comparisons amongst these databases are lacking for pharmacy faculty. The objective of this work was to compare scholarly metrics from three commonly utilized databases and a social networking site focused on data from research-intensive colleges of pharmacy and to identify factors associated with database differences. Scholarly metrics were obtained from Scopus, Web of Science, Google Scholar, and ResearchGate for faculty from research-intensive (Carnegie Rated R1, R2, or special focus) United States pharmacy schools with at least two million USD in funding from the National Institutes of Health. Metrics were compared and correlations were performed. Regression analyses were utilized to identify factors associated with database differences. Significant differences in scholarly metric values were observed between databases despite the high correlations, suggestive of systematic variation in database reporting. Time since first publication was the most common factor that was associated with database differences. Google Scholar tended to have higher metrics than all other databases, while Web of Science had lower metrics relative to other databases. Differences in reported metrics between databases are apparent, which may be attributable to the time since first publication and database coverage of pharmacy-specific journals. These differences should be considered by faculty, reviewers, and administrative staff when evaluating scholarly performance.

Corporate Social Responsibility and Performance in SMEs: Scientific Coverage

The objective of this research is to analyze the scientific production indexed in the international Scopus database on the subject of “corporate social responsibility and corporate social performance” in small and medium-sized enterprises. In the literature, it is currently possible to observe how large corporations undertake social responsibility actions as a usual practice. However, in the case of small and medium-sized enterprises, the reality is different due to their high heterogeneity. To fulfil the proposed objective, a bibliometric analysis is carried out, identifying 277 articles on the subject. It is observed that scientific production is concentrated in a period of 18 years (2000–2018), the majority being qualitative studies.

Comparison of bibliographic data sources: Implications for the robustness of university rankings

Universities are increasingly evaluated on the basis of their outputs. These are often converted to simple and contested rankings with substantial implications for recruitment, income, and perceived prestige. Such evaluation usually relies on a single data source to define the set of outputs for a university. However, few studies have explored differences across data sources and their implications for metrics and rankings at the institutional scale. We address this gap by performing detailed bibliographic comparisons between Web of Science (WoS), Scopus, and Microsoft Academic (MSA) at the institutional level and supplement this with a manual analysis of 15 universities. We further construct two simple rankings based on citation count and open access status. Our results show that there are significant differences across databases. These differences contribute to drastic changes in rank positions of universities, which are most prevalent for non-English-speaking universities and those outside the top positions in international university rankings. Overall, MSA has greater coverage than Scopus and WoS, but with less complete affiliation metadata. We suggest that robust evaluation measures need to consider the effect of choice of data sources and recommend an approach where data from multiple sources is integrated to provide a more robust data set.

Unlocking the Linear Lock-In: Mapping Research on Barriers to Transition

The linear paradigm of take-make-dispose in production and consumption patterns impedes the achievement of global sustainability goals. Strategies for maintaining the added value of resources and circulating them have been discussed as promising for the future. There are, however, many barriers to be addressed to overcome the linear lock-in. The large body of literature on these barriers is notably diverse in terms of theory, methods, sectors, products, and settings. This demonstrates the complexity of delineating implications to the practice and research needs. Without a common framework to analyse barriers, knowledge does not accumulate, hindering the development and implementation of solutions and policies that could effectively address the barriers. In this article, we developed a systematic map of studies on barriers related to the circular transition. The purpose was twofold: (1) to classify published research on barriers; (2) to provide a searchable database for future more rigorous systematic literature reviews. We reviewed the abstract of 527 publications and classified the study according to a developed scheme. This classification scheme includes the research paradigms (circular economy, sharing economy, collaborative consumption and product-service systems), circular strategy (recycling, remanufacturing, component/product reuse, and access-based consumption), country, sector/industry/product, and research approach and method. The resulting research map is open source, serving also as an adaptive digital database for researchers alike to perform systematic reviews and contribute further to its collaborative development.

Assessment of the NIH-supported relative citation ratio as a measure of research productivity among 1687 academic neurological surgeons

OBJECTIVE

Publication metrics such as the Hirsch index (h-index) are often used to evaluate and compare research productivity in academia. The h-index is not a field-normalized statistic and can therefore be dependent on overall rates of publication and citation within specific fields. Thus, a metric that adjusts for this while measuring individual contributions would be preferable. The National Institutes of Health (NIH) has developed a new, field-normalized, article-level metric called the "relative citation ratio" (RCR) that can be used to more accurately compare author productivity between fields. The mean RCR is calculated as the total number of citations per year of a publication divided by the average field-specific citations per year, whereas the weighted RCR is the sum of all article-level RCR scores over an author's career. The present study was performed to determine how various factors, such as academic rank, career duration, a Doctor of Philosophy (PhD) degree, and sex, impact the RCR to analyze research productivity among academic neurosurgeons.

METHODS

A retrospective data analysis was performed using the iCite database. All physician faculty affiliated with Accreditation Council for Graduate Medical Education (ACGME)-accredited neurological surgery programs were eligible for analysis. Sex, career duration, academic rank, additional degrees, total publications, mean RCR, and weighted RCR were collected for each individual. Mean RCR and weighted RCR were compared between variables to assess patterns of analysis by using SAS software version 9.4.

RESULTS

A total of 1687 neurosurgery faculty members from 125 institutions were included in the analysis. Advanced academic rank, longer career duration, and PhD acquisition were all associated with increased mean and weighted RCRs. Male sex was associated with having an increased weighted RCR but not an increased mean RCR score. Overall, neurological surgeons were highly productive, with a median RCR of 1.37 (IQR 0.93-1.97) and a median weighted RCR of 28.56 (IQR 7.99-85.65).

CONCLUSIONS

The RCR and its derivatives are new metrics that help fill in the gaps of other indices for research output. Here, the authors found that advanced academic rank, longer career duration, and PhD acquisition were all associated with increased mean and weighted RCRs. Male sex was associated with having an increased weighted, but not mean, RCR score, most likely because of historically unequal opportunities for women within the field. Furthermore, the data showed that current academic neurosurgeons are exceptionally productive compared to both physicians in other specialties and the general scientific community.

Cultural and Natural Resources in Tourism Island: Bibliometric Mapping

Island ecosystems have very specific physical, economic and socio-cultural characteristics, which are shared by most of these ecosystems regardless of their geographical area. These characteristics include well defined geographical boundaries that lead to a greater degree of isolation, lack of economically exploitable resources, great external dependence for consumption, cultural and natural heritage with a high uniqueness level and a high concentration of endemic plant and animal species. All of them are responsible for the high development dependence level linked to the tourism activity of these ecosystems. Thus, island ecosystems are currently an important international tourism destination, where a great diversity of very attractive natural and cultural resources and of great heritage value are concentrated. This fact allows for the development of tourism activities of great heterogeneity among countries or regions of the world that host these island ecosystems. The aim of this research was to identify and analyze, through a bibliometric and bibliographic analysis, the scientific production indexed in the international Scopus database, which addresses the subject of use of cultural and natural resources by tourism in island ecosystems. This scientific mapping allows us to observe the evolution of scientific production in this field of study. The results show that this is a new subject (a large number of transient authors), predominantly affiliated with the United States and Spain. The most followed research lines to date are destination management followed very far by responsible environmental behavior and the impacts of sustainable development. However, the keywords with the highest co-occurrence show that the hot topics are tourism exploitation in the ecotourism field and sustainable tourism development. This research is considered the first bibliometric study carried out which is related to this thematic approach, providing a clear in-depth analysis for researchers and thereby facilitating the approach of future research work.

Comparative Analysis of Web of Science and Scopus on the Energy Efficiency and Climate Impact of Buildings

Although the body of scientific publications on energy efficiency and climate mitigation from buildings has been growing quickly in recent years, very few previous bibliometric analysis studies exist that analyze the literature in terms of specific content (trends or options for zero-energy buildings) or coverage of different scientific databases. We evaluate the scientific literature published since January 2013 concerning alternative methods for improving the energy efficiency and mitigating climate impacts from buildings. We quantify and describe the literature through a bibliometric approach, comparing the databases Web of Science (WoS) and Scopus. A total of 19,416 (Scopus) and 17,468 (WoS) publications are analyzed, with only 11% common documents. The literature has grown steadily during this time period, with a peak in the year 2017. Most of the publications are in English, in the area of Engineering and Energy Fuels, and from institutions from China and the USA. Strong links are observed between the most published authors and institutions worldwide. An analysis of keywords reveals that most of research focuses on technologies for heating, ventilation, and air-conditioning, phase change materials, as well as information and communication technologies. A significantly smaller segment of the literature takes a broader perspective (greenhouse gas emissions, life cycle, and sustainable development), investigating implementation issues (policies and costs) or renewable energy (solar). Knowledge gaps are detected in the areas of behavioral changes, the circular economy, and some renewable energy sources (geothermal, biomass, small wind). We conclude that (i) the contents of WoS and Scopus are radically different in the studied fields; (ii) research seems to focus on technological aspects; and (iii) there are weak links between research on energy and on climate mitigation and sustainability, the latter themes being misrepresented in the literature. These conclusions should be validated with further analyses of the documents identified in this study. We recommend that future research focuses on filling the above identified gaps, assessing the contents of several scientific databases, and extending energy analyses to their effects in terms of mitigation potentials.

Citation behavior of Pondicherry University faculty in digital environment: a survey

Purpose

The purpose of this paper is to understand the citation behavior of Pondicherry University faculty with a focus on their recent publication experience, indexed in Scopus. The paper endeavors to gain an insight into their pattern of citation of scientific papers and attempts to understand the underlying motive in doing so especially in an era where information resources have transitioned from print to digital.

Design/methodology/approach

The study adopted a judgmental sample consisting of 100 selected faculty members whose recent papers were indexed by Scopus database. A pre-defined questionnaire consisting of demographic profile and 23 items on citation trust and authority statements of citing sources was self-administered to them.

Findings

The findings of the study indicate that the citation behavior of faculty in Pondicherry University is complex and multi-faceted. Although majority of the faculty depicted an inclination toward normative citation behavior (concerned with the intellectual content of the work), there are others who displayed social constructivist (concerned with the social aspects of the work) citation behavior as well. However, in spite of the differences observed in the citation behavior of the faculty, it was observed that they remained traditional while making trust decisions even in the digital era. Finally, findings suggest no statistical significant difference when it comes to variables, such as gender and discipline in the citation behavior of the faculty.

Originality/value

Given the ever-increasing importance of citation in judging the quality of research journals, in ranking institutions and in determining the efficacy of faculty in India, author-based approach of understanding citer motivation definitely carry research value.

The Emerging Social Science Literature on Health Technology Assessment: A Narrative Review

BACKGROUND

Social scientists have paid increasing attention to health technology assessment (HTA). This paper provides an overview of existing social scientific literature on HTA, with a focus on sociology and political science and their subfields.

METHODS

Narrative review of key pieces in English.

RESULTS

Three broad themes recur in the emerging social science literature on HTA: the drivers of the establishment and concrete institutional designs of HTA bodies; the effects of institutionalized HTA on pricing and reimbursement systems and the broader society; and the social and political influences on HTA decisions.

CONCLUSION

Social scientists bring a focus on institutions and social actors involved in HTA, using primarily small-N research designs and qualitative methods. They provide valuable critical perspectives on HTA, at times challenging its otherwise unquestioned assumptions. However, they often leave aside questions important to the HTA practitioner community, including the role of culture and values. Closer collaboration could be beneficial to tackle new relevant questions pertaining to HTA.

The difference in referencing in Web of Science, Scopus, and Google Scholar

AIMS

How often a medical article is cited is important for many people because it is used to calculate different variables such as the h-index and the journal impact factor. The aim of this analysis was to assess how the citation count varies between Web of Science (WoS), Scopus, and Google Scholar in the current literature.

METHODS

We included the top 50 cited articles of four journals ESC Heart Failure; Journal of cachexia, sarcopenia and muscle; European Journal of Preventive Cardiology; and European Journal of Heart Failure in our analysis that were published between 1 January 2016 and 10 October 2019. We recorded the number of citations of these articles according to WoS, Scopus, and Google Scholar on 10 October 2019.

RESULTS

The top 50 articles in ESC Heart Failure were on average cited 12 (WoS), 13 (Scopus), and 17 times (Google Scholar); in Journal of cachexia, sarcopenia and muscle 37 (WoS), 43 (Scopus), and 60 times (Google Scholar); in European Journal of Preventive Cardiology 41 (WoS), 56 (Scopus), and 67 times (Google Scholar); and in European Journal of Heart Failure 76 (WoS), 108 (Scopus), and 230 times (Google Scholar). On average, the top 50 articles in all four journals were cited 41 (WoS), 52 (Scopus, 26% higher citations count than WoS, range 8-42% in the different journals), and 93 times (Google Scholar, 116% higher citation count than WoS, range 42-203%).

CONCLUSION

Scopus and Google Scholar on average have a higher citation count than WoS, whereas the difference is much larger between Google Scholar and WoS.

Early Impact of the Western Journal of Emergency Medicine CDEM/CORD Special Issue in Educational Research & Practice

Introduction

In 2015, with a stated goal of disseminating best teaching practices and developing a community of educational scholars, the Council of Emergency Medicine Directors (CORD) and the Clerkship Directors of Emergency Medicine (CDEM) created an annual Special Issue in Educational Research and Practice (Special Issue) in cooperation with the Western Journal of Emergency Medicine. The intention of this study was to analyze the impact of this effort to date.

Methods

Bibliometric data was gathered on all four special issues, 2015–2019, from the Web of Science and then verified with the eScholarship website. Authorship, academic affiliation, date published, article type, and format were tabulated for descriptive analysis. Using metrics from Google Scholar, alternative scholarly impact metrics (altmetrics), and the eScholarship website, the authors identified top articles and grouped them into themes.

Results

Of the 136 articles included in the first four years of the Special Issue, 126 represented peer-reviewed publications with an overall acceptance rate of 25.0% (126/505). Authors from this cohort represented 103 of the 182 (56.6%) Accreditation Council for Graduate Medical Education (ACGME) programs in existence at the time of the inaugural issue. Multi-institutional studies represented 34.9% (44/126) of the peer-reviewed publications. Traditional and alternative publication metrics are reported to assess the impact of articles from the Special Issues.

Conclusion

The Special Issue is a proven outlet to share best practices, innovations, and research related to education. Additionally, the infrastructure of this process promotes the development of individual faculty and a community of teaching scholars.

Bibliometric Analysis of the Mass Transport in a Gas Diffusion Layer in PEM Fuel Cells

The growth trend of publications in the field of Proton Exchange Membrane Fuel Cell (PEMFC) was analyzed using bibliometric techniques to the identification of the areas with significant development and the orientations that have guided the research on energy cells. This study extracted the data from Scopus and Web of Science (WoS) databases to compare the bibliometric indicators of the published productions. In spite of bibliometric analysis advantages to knowing about the trends in a study area, this research requires methods to support the investigation process through the selection of a relevant bibliographic portfolio. This study applied the Methodi Ordinatio that provides a new approach to achieve it. A proposed list of the articles ranked by InOrdinatio is presented to compose the final portfolio. The obtained results in the research sub-theme of the Mass Transport in Gas Diffusion Layer (GDL) confirm the complexity in the study area by presenting erratic patterns of exponential growth. United States, China, and Japan are the leading countries on PEMFC publications. These countries have in common a strong spending by the business sector for R&D, and their gross domestic product is greater than 2%.

An evaluation of Web of Science, Scopus and Google Scholar citations in operations management

Purpose

Ongoing deliberation about how research productivity should be measured is exacerbated by extensive disparity between the number of citations for scholarly works reported by commercial academic search engines and Google Scholar (GS), the premier web crawling service for discovering research citations. Disparities identified in citation comparison studies have also led to disagreement about the value of the higher number of citations for social sciences and business scholarly articles consistently reported by GS. The purpose of this paper is to extend previous database citation comparison studies by manually analyzing a sample of unique GS citations to a leading operations management journal (i.e. citations found only in GS and not the commercial search engines) to reveal just where these additional citations are coming from.

Design/methodology/approach

In addition to comparing citation counts for the three databases, unique GS citation data for the sample of journal articles was manually captured and reviewed. The authors’ approach provides a much more in-depth examination of the provenance of GS citations than is found in previous studies.

Findings

The findings suggest that concerns about the value of unique GS citations may not be warranted since the document types for the unique GS citing documents identified in the analysis are dominated by familiar scholarly formats. Predominantly authentic and validated journal publications, dissertations, conference papers, and book and book chapters accounted for the large majority of the unique GS citations analyzed.

Practical implications

The study lends further credence to contentions that the use of citations reported in GS is appropriate for evaluating research impact in disciplines where other formats beyond the English-language journal article are valued.

Originality/value

Developing a more informed understanding of the provenance of unique GS citations in the authors’ field is important because many scholars not only aspire to publish in elite journals with high impact factors based on citation counts provided by commercial databases to demonstrate quality, but also report the larger number of citations for their publications that are reported by GS to demonstrate impact. The in-depth manual analysis suggests that GS provides a more nuanced and comprehensive representation of research impact and international scope than the commercial databases.
