Analysis of the scientific production of the effect of COVID-19 on the environment: A bibliometric study

The fight against COVID-19 since January 2020 has become the top priority of more than 200 countries. In order to offer solutions to eradicate this global pandemic, the scientific community has published hundreds of articles covering a wide range of areas of knowledge. With the aim of synthesizing these publications, academics are resorting to bibliometric analyses from the perspectives of the disciplines such as biology, medicine, socioeconomics and tourism. Yet no bibliometric analysis has explored the diffuse and little-known growth of COVID-19 scientific publications in the field of environmental studies. The current study is the first of this type to fill this research gap. It has resorted to SciMAT software to evaluate the main topics, authors and journals of publications on the subject of COVID-19 combined with environmental studies spanning the period between 1 December 2019 and 6 September 2020. The search yielded a collection of 440 articles published in scientific journals indexed on by Web of Science and Scopus databases. These publications can be broken down into six main themes: (i) a sharp reduction in air pollution and an improvement of the level of water pollution; (ii) the relationship of wind speed (positive), ultraviolet radiation (positive) and humidity (negative) with the rate of infections; (iii) the effect of the pandemic on the food supply chain and waste habits; (iv) wastewater monitoring offers a great potential as an early warning sign of COVID-19 transmission; (v) artificial intelligence and smart devices can be of great use in monitoring citizen mobilization; and (vi) the lessons gleaned from the pandemic that help define actions to mitigate climate change. The results of the current study therefore offer an agenda for future research and constitute a starting point for academics in the field of environmental studies to evaluate the effects of COVID-19.

What Do We Know about Co-Working Spaces? Trends and Challenges Ahead

Co-working spaces (CWSs) have emerged as a distinctive phenomenon in the sharing economy. They are collaborative environments that feed innovation and creativity under the slogan “working alone together”. While policy makers and scholars were optimistic about their role in promoting entrepreneurial endeavours and fostering growth, the spread of the COVID-19 across the world has drastically changed the way we work, communicate, and navigate daily life. This study offers a comprehensive review of the existing literature on CWSs. To do so, a bibliometric analysis is proposed, combining the use of traditional bibliometric tools with science mapping techniques. A total of 118 documents are reviewed and the results are presented at two different levels: (1) descriptive analysis of the status of the research on a CWS and (2) its conceptual structure (topics and trends). The study concludes with some directions for future research. Specifically, based on the recurrent topics discussed up to date in the literature, it is possible to identify four key areas—i.e., geographical location, physical space, business models and inclusive communities—that are promising for research and that may bring useful insights for defining co-working’s place in a post-pandemic society.

Where to Go with Corporate Sustainability? Opening Paths for Sustainable Businesses through the Collaboration between Universities, Governments, and Organizations

This study aims to identify and analyze the Scientific–Technical Scenario on Corporate Sustainability (STS-CS) and propose a Triple Helix-based framework for its development and guidance of future scientific and technological investments. The study was developed using a combined method of bibliometric analysis and content analysis of scientific papers and technical publications (patents, white papers, publications from public bodies, etc.). The scientific papers were searched in the Scopus database and technical publications in the Orbit Intelligence, ProQuest, and UN Global Compact platforms. The STS-CS was analyzed in light of the scientific and technical literature and experience of the authors of the study, which allowed the proposition of the framework with initiatives expanded and adapted to the domains of the Triple Helix sectors “Universities,” “Governments”, and “Organizations” through a process of enriching the good practices identified in the CS scenarios. The main academic contribution of this work is the upgrade of the scientific block of knowledge on CS based on cooperation between the sectors of Triple Helix that expands and deepens the research aimed at contributing to sustainable business development. As for the applied contributions, companies can identify business opportunities to increase their profits in a sustainable way, governments can find suggestions for public measures for the development of CS, and universities can identify recommendations for training professionals capable of managing socio-economic issues and developing partnerships with companies for the innovation and development of sustainable products and processes.

A Bibliometric Network Analysis of Coronavirus during the First Eight Months of COVID-19 in 2020

The COVID-19 pandemic has affected all aspects of society. Researchers worldwide have been working to provide new solutions to and better understanding of this coronavirus. In this research, our goal was to perform a Bibliometric Network Analysis (BNA) to investigate the strategic themes, thematic evolution structure and trends of coronavirus during the first eight months of COVID-19 in the Web of Science (WoS) database in 2020. To do this, 14,802 articles were analyzed, with the support of the SciMAT software. This analysis highlights 24 themes, of which 11 of the more important ones were discussed in-depth. The thematic evolution structure shows how the themes are evolving over time, and the most developed and future trends of coronavirus with focus on COVID-19 were visually depicted. The results of the strategic diagram highlight 'CHLOROQUINE', 'ANXIETY', 'PREGNANCY' and 'ACUTE-RESPIRATORY-SYNDROME', among others, as the clusters with the highest number of associated citations. The thematic evolution. structure presented two thematic areas: "Damage prevention and containment of COVID-19" and "Comorbidities and diseases caused by COVID-19", which provides new perspectives and futures trends of the field. These results will form the basis for future research and guide decision-making in coronavirus focused on COVID-19 research and treatments.

A scientometric analysis of ICT-assisted disaster management

In recent years, natural and manmade disasters such as floods, earthquakes, wildfires, and tsunamis have occurred with human losses and environmental deterioration. Henceforth, to reduce the damage caused by these catastrophic events, the administration and government need to track victims and perform synchronized relief efforts on time at the disaster sites. The promising technologies of Internet communication technology (ICT), like the Internet of things, cloud computing, and data analytics, can assist various phases of disaster management. Moreover, the role of higher education spans all stages of disaster management: preparedness, response, and recovery. As educational and research contributions, higher educational institutes are essentially involved in all the disaster management stages to contribute to society broadly. Henceforth, the scientific analysis of disaster management literature is required to analyze the overall structure and developments in this domain. This study presents a scientometric analysis that evaluates the ICT-assisted disaster management research over the last 15 years (2005-2020). It presents various empirical ways to analyze the evolution, status, and result of ICT-assisted in disaster management research. This study provides extensive insight into the publication growth, citation analysis, collaboration, and keyword co-occurrence analysis for technological trends of the ICT-assisted disaster management research. It identifies key journals, countries, and organizations that significantly contributed to this research domain. Overall, this study presents various patterns, research trends, and collaborations as the basic structure for future research in this field.

The Role of Value Stream Mapping in Healthcare Services: A Scoping Review

Lean healthcare aims to manage and improve the processes in the healthcare sector by eliminating everything that adds no value by improving quality of services, ensuring patient safety and facilitating health professionals’ work to achieve a flexible and reliable organization. Value Stream Mapping (VSM) is considered the starting point of any lean implementation. Some papers report applications of VSM in healthcare services, but there has been less attention paid to their contribution on sustainability indicators. The purpose of this work is to analyze the role of VSM in this context. To do so, a scoping review of works from recent years (2015 to 2019) was done. The results show that most applications of VSM reported are in the tertiary level of care, and the United States of America (USA) is the country which leads most of the applications published. In relation with the development of VSM, a heterogeneity in the maps and the sustainability indicators is remarkable. Moreover, only operational and social sustainability indicators are commonly included. We can conclude that more standardization is required in the development of the VSM in the healthcare sector, also including the environmental indicators.

Insights from Circular Economy Literature: A Review of Extant Definitions and Unravelling Paths to Future Research

The circular economy (CE) has become one of the prominent topics in both natural science and management literature over the last few decades. CE is a dual-loop regenerative system that focuses on the effective and efficient utilization of resources in the ecosystem, which is beneficial to environmental and economic performance optimization. Dual CE initiatives allow firms to increased resource eco-efficiency, as well as resource effectiveness. CE has profound consequences for economic and operational advantage. This reinforces the need for reflection on the definition that may provide guidelines to assess and advance the depth and diversity of the field. We aim to provide a definitional analysis of the CE and suggest future research streams to advance the existing literature. For this purpose, we employed a systematic literature review to collect related publications in the CE. As a result of this, a total of 91 papers were selected, studied, and analyzed. We proposed a sound definition of a circular economy that includes the main identified elements, organizational planning processes, customers and society, utilization of the ecosystem, and economic resource flows. Moreover, future direction agenda, in CE research, is suggested considering three research streams: (1) circular design as value creation and capture, (2) antecedents of key activities, and (3) consequences of key processes. There is limited empirical research conducted on CE, and much of the existing research focuses on theoretical, conceptual, and normative. A few empirical research studies are mainly cross-sectional in their focus and are confined to developing and emerging economies. We hope this study’s findings will extend the field of CE, in which some of the most influential information regarding CE literature is provided. This study suggests that the development of CE initiatives plays an important role in the growing digital transformation in the value chain. There have been limited research studies in the interface of circular economy and Industry 4.0. Future research studies may investigate the extent to which digital transformation can increase the implementation of CE, and their influence on digital performance management.

The Organizational Commitment in the Company and Its Relationship With the Psychological Contract

Business organizations in their work environment, aspire to create a high level of performance and low levels of absenteeism and turnover. Organizational commitment is considered a key factor in achieving this objective, however, it can be conditioned by several factors, among which is the psychological contract. The literature has related the organizational commitment with the fulfillment of the psychological contract framing it as one of the explanatory variables. This work aims to investigate research trends on psychological contract and organizational commitment. For this purpose, bibliometric techniques and the software SciMAT have been used. 220 journal articles indexed in Web of Science (WoS) were analyzed. The findings indicate that the theme chosen for this review is valid. Based on the relationship between the two concepts, as the most recurrent themes, issues such as the sense of justice and the consequences of the violation of the psychological contract, normative commitment, HR management or job insecurity are addressed. However, in the last period analyzed (2015–2018), publications related to more sensitive topics to the present time emerge, such as the employability or the impact of these two concepts in the new generations (millennial and generation-Y) or the retention of talent. On the other hand, shortcomings are detected in the research on the ideologically charged psychological contract, the analysis of the organizational context or cultural and demographic factors in relation to both theoretical constructs. The contribution of this work lies in giving visibility to scientific results, which will serve business organizations as instruments for decision making in their labor management and, for the scientific community, as knowledge of the research spaces to explore.

The Intellectual Structure of Social and Sustainable Public Procurement Research: A Co-Citation Analysis

Public procurement has recently taken into account social and sustainable factors, increasing academic literature in this field. The aim of this paper is to map the intellectual structure of social and sustainable public procurement research by means of delimiting the scientific domain’s research traditions, its disciplinary composition, and influential research topics. Given that there is a literature gap in bibliometric studies applied to this field, we conducted a co-citation analysis to identify the intellectual structure of this area of knowledge. Co-citation analyses identify networks of interconnections and, consequently, detect the most (and the least) active research areas, being a good complement to traditional literature reviews. This article contributes to science development because it is the first paper to carry out a bibliometric analysis in the field of social and sustainable public procurement, as well as the first one to conduct a co-citation analysis among public procurement research. Consequently, it is also the first article to detect which papers have become burst in this research field. The results show twelve different clusters of publications that were cited by researchers who wrote papers on social and sustainable public procurement. In other words, the sources of knowledge that scholars used as references are analysed, identifying papers that can be considered turning points, as well as those that became specially cited over a discrete period of time. Six different research trends were identified over the last decade in regard to social and sustainable public procurement research. The conclusions highlight the relevance of the findings, especially because they provide guidance to researchers when conducting literature reviews, given that the most significant journals and papers are identified.

An overview of research on natural resources and indigenous communities: a bibliometric analysis based on Scopus database (1979-2020)

Indigenous people constitute an important section of society in many countries. Despite being a numerically smaller section, they are culturally diverse and distributed mostly in valuable natural resources-rich regions worldwide. In the era of globalization, industrialization, and trade liberalization, indigenous communities have become more vulnerable to displacement, land alienation, cultural erosion, and social exclusion. During the last few decades, researchers have tried to evaluate and document their problems and prospects. The present study analyzes the trends and characteristics of research and development conducted about indigenous communities. The research hotspots based on keywords, productive researchers, and journals during 1979-2020 were mapped using the Scopus database. The analysis was carried out using the bibliometrix R-package and VOSviewer software tool. Consistent growth in the number of studies and citations on indigenous communities concerning environmental conservation, natural resources, and economic development was observed during the last four decades. The present findings reveal that research on the indigenous community has attracted the attention of the scientific community in recent years. Qualitative studies with methodological rigor, having potential for social and policy implications, are warranted to understand and respect ingrained cultural and socio-economic diversity among these communities. Graphical abstract.

Strategic planning research through fifty years of long range planning: A bibliometric overview

Long Range Planning (LRP) is the first journal focused on strategic planning. It was created in 1968 by the Long Range Planning Society, and it celebrated its 50 th anniversary in 2018. This event led to the presentation of a complete bibliometric study aimed at identifying the most significant results that occurred in the journal during this period. For this purpose, bibliometric data were collected from the Web of Science Core Collection database, and two bibliometric approaches were used to analyze the journal's publications: a performance analysis and a graphical mapping of the literature. The first of these uses a wide range of productivity and influence indicators that include the number of publications and citations, the h-index, and citations by paper, among others. The second approach uses the VOSviewer software to deliver a graphical view of the various intellectual connections within LRP. The results of both bibliometric approaches are consistent and confirm LRP as a leading journal in strategic planning and management, with increasing participation of authors and universities from countries around the world.

The Sources of Knowledge of the Economic and Social Value in Sport Industry Research: A Co-citation Analysis

The aim of this article is to map the intellectual structure of scholarship on economic and social value in the sport industry. Given that bibliometric techniques are specially appropriate for identifying the intellectual structures of a field of knowledge and complement traditional literature reviews, a co-citation bibliometric analysis has been applied. This kind of analysis identifies networks of interconnections. Therefore, we aim to detect both the most and the least active research areas in this field, as well as their sub-disciplinary composition. There is an abundance of literature on sport efficiency and economic efficiency in the sport industry, our main conclusion is the identification of a literature gap in regard to social value in sport organisations, which is expected to be a research opportunity for scholars. This is in line with the lack of standardisation in the measurement for social value in sport organisations. In fact, similar to analysis undertaken in the past few decades of other industries with contributions to stakeholders and the multi-fiduciary theory of stakeholders, both the creation of social value indicators for sport entities and the empirical analysis of social efficiency in sport institutions, are identified and outlined as future areas of research. Therefore, this bibliometric analysis will contribute to determine the future challenges that this area of research will face in the following years so as to fill the literature gap identified.

Sustainability and Kaizen: Business Model Trends in Healthcare

Kaizen, or continuous improvement, is a management tool that allows the identification of activities that have no value in the processes examined. This identification leads to the improvement of these processes within any organization and promotes economic and social sustainability, and to a lesser extent environmental sustainability. Kaizen, already widely and successfully employed in the industrial sector, is now being applied in the health sector. However, the health sector tends to publish only the results of how processes have been improved in finely focused areas and the resulting benefits. The majority of the benefits focus on time and cost reduction. In this study, the authors carried out a bibliometric analysis using the Scimat program, which maps the thematic evolution of Kaizen in the health sector and its relationship with sustainability, in order to promote the interest of the health sector for this type of process improvement. The findings confirm that the implementation of Kaizen is recent and constantly evolves and grows, and that it can help economic and social sustainability, and to a lesser extent environmental sustainability.

100 Years of Scientific Evolution of Work and Organizational Psychology: A Bibliometric Network Analysis From 1919 to 2019

In this study, we explore a 100 years of Work and Organizational Psychology (WOP). To do this, we carry out a bibliometric performance and network analysis (BPNA) to understand the evolution structure and the most important themes in the field of study. To perform the BNPA, 8,966 documents published since 1919 were exported from the Web of Science and Scopus databases. The SciMAT software was used to process data and to create the evolution structure, the strategic diagram, and the thematic network structure of the strategic themes of the field of WOP. We identified 29 strategic clusters and discuss the most important themes (motor themes) and their relationship with other clusters. This research presents the complete evolution of the field of study, identifying emerging themes and others with a high degree of development. We hope that this work will support researchers and future research in the field of WOP.

Landscape and Tourism: Evolution of Research Topics

Tourism and landscape are broad and complex scientific research fields, as is the synergy between them has given rise to a volume of articles diverse in nature, subject matter and methodology. These difficulties mean that, at present, there is no complete theoretical framework to support this tourism and landscape research, nor complete knowledge of its structure and organization. This motivates the present work, which constitutes the first attempt at mapping this research topic by applying bibliometric techniques using VOSviewer and Science Mapping Analysis Software Tool (SciMAT) software. A total of 3340 articles from journals indexed in Web of Science were analyzed. The results obtained confirm that interest in the study of these concepts has been growing, especially in the last decade. The main contribution of this work lies in the identification of work themes that were basic to the construction of the field but that are currently in decline, such as “cultural heritage” and other themes important to the field that should continue to be dealt with, such as “national parks” or “geotourism”. The transversal nature of sustainability that appears in the network of keywords related to currently emerging themes, such as “planning” and “environment”, is also highlighted and reinforced.

The scholar's best friend: research trends in dog cognitive and behavioral studies

In recent decades, cognitive and behavioral knowledge in dogs seems to have developed considerably, as deduced from the published peer-reviewed articles. However, to date, the worldwide trend of scientific research on dog cognition and behavior has never been explored using a bibliometric approach, while the evaluation of scientific research has increasingly become important in recent years. In this review, we compared the publication trend of the articles in the last 34 years on dogs’ cognitive and behavioral science with those in the general category “Behavioral Science”. We found that, after 2005, there has been a sharp increase in scientific publications on dogs. Therefore, the year 2005 has been used as “starting point” to perform an in-depth bibliometric analysis of the scientific activity in dog cognitive and behavioral studies. The period between 2006 and 2018 is taken as the study period, and a backward analysis was also carried out. The data analysis was performed using “bibliometrix”, a new R-tool used for comprehensive science mapping analysis. We analyzed all information related to sources, countries, affiliations, co-occurrence network, thematic maps, collaboration network, and world map. The results scientifically support the common perception that dogs are attracting the interest of scholars much more now than before and more than the general trend in cognitive and behavioral studies. Both, the changes in research themes and new research themes, contributed to the increase in the scientific production on the cognitive and behavioral aspects of dogs. Our investigation may benefit the researchers interested in the field of cognitive and behavioral science in dogs, thus favoring future research work and promoting interdisciplinary collaborations.

Visualizing the Intellectual Structure and Evolution of Intelligent Transportation Systems: A Systematic Analysis of Research Themes and Trends

According to the United Nations, 70% of the world’s population will live in cities by 2050. This growth will be reflected in the demand for better services that should be adjusted to the collective and individual needs of the population. Governments and organizations are working on defining and implementing strategies that will enable them to respond to these challenges. The main challenges are related to transport and its management, considering transportation as a core issue in the economy, sustainability, and development of the regions. In this way, the Intelligent Transportation Systems (ITS) play a key role in the response to these scenarios, being that they are the framework where the new hardware and software tools are integrated, allowing an efficient development of transportation systems management, attending to aspects such as: traffic management, communications between vehicles and infrastructures, and security, among others. Nevertheless, the concept of ITS evolves rapidly so it is necessary to understand its evolution. To do that, the current research develops a thematic analysis of ITS in literature, evaluating the intellectual structure and its evolution using SciMAT, quantifying the main bibliometric performance indicators, and identifying the main research areas, authors, journals, and countries. To this purpose, the publications related to ITS from 1993 to 2019 available in the Web of Science (WoS) Core Collection were retrieved (7649 publications) and analyzed. Finally, one of the main results is the latest research themes map of ITS, considering its intellectual structure, evolution, and relationship. It assists in the definition and implementation of strategies, the identification of the scientific, academic, and business opportunities, and future research lines to consolidate the role of ITS in the new city models.

30 years of parasitology research analysed by text mining

Bibliometric methods were used to analyse the major research trends, themes and topics over the last 30 years in the parasitology discipline. The tools used were SciMAT, VOSviewer and SWIFT-Review in conjunction with the parasitology literature contained in the MEDLINE, Web of Science, Scopus and Dimensions databases. The analyses show that the major research themes are dynamic and continually changing with time, although some themes identified based on keywords such as malaria, nematode, epidemiology and phylogeny are consistently referenced over time. We note the major impact of countries like Brazil has had on the literature of parasitology research. The increase in recent times of research productivity on 'antiparasitics' is discussed, as well as the change in emphasis on different antiparasitic drugs and insecticides over time. In summary, innovation in parasitology is global, extensive, multidisciplinary, constantly evolving and closely aligned with the availability of technology.

Fleet Management and Control System for Medium-Sized Cities Based in Intelligent Transportation Systems: From Review to Proposal in a City

In medium-sized cities in developing countries, transit services without dedicated lanes have issues related to route compliance, schedules, speed control, and safety. An efficient way for dealing with this issue is the use of Information and Communication Technologies (ICT), to implement a Fleet Management and Control Systems (FMCS). Such implementation can be performed using Intelligent Transportation Systems (ITSs), which allow integration of services and adequate standardization. This article features: (a) a literature review, related to FMCS based on ITS and enabling technologies, (b) design of the ITS architecture of an FMCS, and (c) some advances in the development of the proposed FMCS in a Colombian city (Popayán). The results of the literature review allowed identifying the most important requirements of FMCS in order to design the ITS architecture and build a prototype featuring the suggested technologies. Finally, some experiments were performed to evaluate the operation of the developed prototype. The results showed evidence of adequate operation in sending and receiving messages from and to four prototypes developed for the vehicles, also complying with the established requirements of location, tracking, exchanged data, and security. This allows continuing the development of the proposed FMCS, with some adjustments.

A Scientometrics Review on Farmland Abandonment Research

Using the Web of Science database, 1498 research articles published between 1900 and 2019 on the subject of farmland abandonment were retrieved. With the help of the SciMAT tool, a theme strategic diagram, overlay map and evolution map represented by keywords were constructed, and the strategic coordinate analysis and data flow analysis methods were used to analyze the research themes, evolutionary states and paths of farmland abandonment in different research time periods. The results show the following: (1) Research on farmland abandonment has rapidly grown in the past ten years, the development of studies on farmland abandonment has become more mature, and the research topics and content have tended to solidify; (2) The research topics of studies on farmland abandonment are mostly centered on forests, patterns, landscapes, land use changes, climate change, etc. The research topics have had strong continuity and few new research hotspots; (3) The study of the ecological environment effect of farmland abandonment is the basic research direction in the field of farmland abandonment and will continue to become a research hotspot; (4) Farmland abandonment has become an important part of the research on land use change and ecosystem processes; (5) The driving force of farmland abandonment includes natural, social and economic factors, among which the socioeconomic factors are the most important driving force, and will continue to be a research hotspot. Finally, this study concludes that the research directions on farmland abandonment in future should strengthen the quantitative assessment of environmental effects of farmland abandonment, information extraction and multiscale simulation monitoring, trend prediction and risk assessment.

Social Life-Cycle Assessment: A Review by Bibliometric Analysis

This study examined the literature on social life-cycle assessment (S-LCA) published in the last 15 years (2003–2018) using bibliometric methods. Applying scientific mapping and analyzing publication performance, the study describes the structure of and trends in S-LCA publications in terms of related subject categories, authors, journals, countries, and highly cited articles. Challenges and research gaps in the S-LCA literature were also explored. The content of related papers published in the ISI Web of Science databases was examined to identify the main themes investigated, evolution of publication activity, and most representative elements. Analyses were conducted with SciMAT software. This tool enables researchers to map research specialties by extracting qualitative information in the specialized literature and representing it using quantitative measures. The results show rapid and exponential growth of the S-LCA research line in the past ten years, with a clear upward trend in related publications (mostly case studies), especially after publication of the UNEP/SETAC Guidelines for Social Life Cycle Assessment of Products in 2009: 66% of all articles published on S-LCA were published during the period 2015–2018, primarily by European authors. The findings also delineate S-LCA as a highly fragmented research field that has been applied to diverse sectors (agriculture, bioenergy, transport, water management, chemical products, electronics, etc.), mainly in non-European countries. Critical questions concerning methods, framework, paradigms, and indicators remain to be resolved. This study provides insight into the publication performance of S-LCA, characterizing its intellectual structure and salient authors and works. In identifying hotspots in the S-LCA research, the study provides a useful state-of-the-art reference guide for academics and reveals critical research gaps and potential research avenues for future studies to advance in consolidating the discipline.

Future research tendencies for solar energy management using a bibliometric analysis, 2000-2019

Using the Scopus database between the years of 2000 and 2019, a bibliometric study was done to analyze the scientific publications in the area of photovoltaic solar energy management. From the preliminary analysis of future research tendencies, ten possibilities of study topics were developed; and due to that it was possible to assume that even though many studies of technological development are found, some insights can still be approached in a way that the practical implementation of solar systems photovoltaic is better used. This data was validated by the analysis performed with the Scimat scientific mapping software under a longitudinal structure, verifying the future tendencies researches mentioned previously.

Visualizing Research on Industrial Clusters and Global Value Chains: A Bibliometric Analysis

In the current digital era, the borders amongst firms are getting blurred when it comes to value creation. Therefore, the traditional configuration of the value chain is frequently replaced by other ones which include the collaborative participation of different agents. Within this context, global value chains, where the value activities are located in different countries, and industrial clusters, which combine competition and cooperation, are attracting a growing attention of both business leaders and scholars in the recent years. Through a bibliometric analysis, this paper disentangles the intellectual and conceptual structure of the research topic of industrial clusters and global value chains. Results show the multidisciplinary character of the topic, including papers published in different areas, such as business, regional studies and world development, as well as its close link with aspects like innovation, regional development, governance or organization. Finally, this study remarks the research lines that could attract more attention in the immediate future.

Methods: A total of 426 articles published between 2000 and 2018 were retrieved from the Clarivate Analytics Web of Science, and then, computer-aided bibliometric analysis as well as Latent Dirichlet Allocation (LDA) topic modeling were conducted on the collection of the data. Results: Descriptive statistics on the increasing number of publications, network analysis of scientific collaboration between countries, word co-occurrence analysis, conceptual structure, and six latent topics (k = 6) identified are discussed. Conclusions: Preventing or managing depression among caregivers is a growing field with the highest priority for the aging population. In the future, collaborating between countries and reflecting cultural backgrounds in caregiver depression research are needed. This study is expected to contribute to the field of psychological distress of caregivers in looking a big picture of the current position through data-driven analysis and moving forward towards a better direction.

Entrepreneurship Through Open Data: An Opportunity for Sustainable Development

Entrepreneurship and open data are key elements in the sustainable development field, improving economic, social, and environmental dimensions. However, entrepreneurship and open data are barely studied together in the literature from a theoretical perspective. Therefore, this study identifies the main themes in the previous studies and proposes a conceptual model for analyzing entrepreneurship through open data. For this purpose, a descriptive analysis and a co-word analysis were performed. Results show that the subject is multidisciplinary, and the main theme of study is how different agents reuse information released by public administrations to generate new entrepreneurial initiatives, especially novel business models associated with new mobile applications. Open data sources, innovation, and business models are studied as critical factors for analyzing entrepreneurship through open data. Likewise, a conceptual model is presented and emerging themes for future research are proposed. Among them, the importance of encouraging collaboration between different agents in the open data ecosystem for service development and improvement is emphasized. Our study identifies an emerging theme that is still in an early phase: The study of sustainable entrepreneurship through open data as a value creation initiative to address global sustainable development.

Research into Neospora caninum-What Have We Learnt in the Last Thirty Years?

BACKGROUND

Neospora caninum has been recognised world-wide, first as a disease of dogs, then as an important cause of abortions in cattle for the past thirty years. Over that time period, there have been improvements in the diagnosis of infection and abortion, new tests have been developed and validated, and it is timely to review progress to date.

METHODS

Bibliometric methods were used to identify major trends and research topics present in the published literature on N. caninum. The tools used were SWIFT-Review, VOSviewer and SciMAT, along with the published papers found in the MEDLINE, Dimensions and Web of Science databases. A systematic review of the published Neospora literature (n = 2933) was also carried out via MEDLINE and systematically appraised for publications relevant to the pathogenesis, pathology and diagnosis of Neospora abortions.

RESULTS

A total of 92 publications were included in the final analysis and grouped into four main time periods. In these four different time periods, the main research themes were "dogs", "abortion", "seroprevalence" and "infection". Diagnostics, including PCR, dominated the first two time periods, with an increased focus on transmission and abortions, and its risk factors in cattle.

CONCLUSIONS

Longitudinal analyses indicated that the main themes were consistently investigated over the last 30 years through a wide range of studies, with evolving emphasis initially on dogs and diagnostic test development, followed by application to cattle, the identification of the risk factors leading to abortion, and in the latter time periods, an understanding of the immunity and a search for vaccines.

Trend Linking of Multiple System Atrophy: A Scientometric Study

AIM

This study aims to add to previous analyses and describe the trends in MSA research from three decades, 1988 to 2018, through assessing the medical literature. Additionally, a collaboration network was analyzed to determine the most common process in development of MSA research.

METHODS

This research was a descriptive survey with a scientometric approach. The data for the present study were collected from the Web of Science (WoS) and search strategy based on Medical Subject Heading (MeSH) term. In this research, the data analysis was performed based on collaboration network and theme analysis.

RESULTS AND CONCLUSION

In this study, 6530 articles were retrieved from 1988 to 2018 divided in three different periods. These articles were drafted by 39,184 authors, 3,865 organizations, 80 countries, and 832 journals. Further, 287 articles with more than 100 citations were found. The global citation score (GCS) was 250,834 times and the average citations per article was 3,841 times. The MSA research field demonstrated a diagram for a chronological period to assess the most relevant themes. Each diagram depended on the sum of documents linked to each research topic. Scientometric analysis of the field of MSA can be regarded as a roadmap for future research and policymaking in this important area.

A Bibliometric Overview of Twitter-Related Studies Indexed in Web of Science

Twitter has been one of the most popular social network sites for academic research; the main objective of this study was to update the current knowledge boundary surrounding Twitter-related investigations and, further, identify the major research topics and analyze their evolution across time. A bibliometric analysis has been applied in this article: we retrieved 19,205 Twitter-related academic articles from Web of Science after several steps of data cleaning and preparation. The R package “Bibliometrix” was mainly used in analyzing this content. Our study has two sections, and performance analysis contains 5 categories (Annual Scientific Production, Most Relevant Sources, Most Productive Authors, Most Cited Publications, Most Relevant Keywords.). The science mapping included country collaboration analysis and thematic analysis. We highlight our thematic analysis by splitting the whole bibliographic dataset into three temporal periods, thus a thematic evolution across time has been presented. This study is one of the most comprehensive bibliometric overview in analyzing Twitter-related studies by far. We proceed to explain how the results will benefit the understanding of current academic research interests on the social media giant.

The most densely researched topic in the largest subject cluster was breast cancer. The most commonly used keywords were breast cancer, quality of life and women.

CONCLUSION

Breast cancer research in the field of nursing has increased in the last decade, and the United States ranked first in terms of publications in this nursing field.

The Tipping Point in the Status of Socially Responsible Consumer Behavior Research? A Bibliometric Analysis

Looking at the impact of society on the environment or, as we write this manuscript in the midst of the COVID-19 crisis, the scenes of consumers hoarding products, we wonder if consumers really do exhibit socially responsible consumer behaviors (SRCB). An initial literature review showed that few studies have addressed this issue, which creates opportunities for the development of new research lines. Furthermore, no study had examined the conceptual evolution or whether SRCB is a developed or fragmented theme from an exhaustive compilation of all previous academic research. To address the proposed research questions, we conducted a bibliometric analysis applied to a corpus of manuscripts on SRCB indexed in the Web of Science (WoS) bibliographic database, from its inception in 1991 up to 2019. Co-word analysis provided a structure of conceptual sub-domains classified based on their density and centrality. In addition, thematic networks were extracted that showed the important associations between the main issues that the SRCB community has addressed, which enabled the authors to examine the subject’s intellectual structuring over almost three decades. The findings showed that the research, over time, has focused most on corporate social responsibility (CSR), this being a motor theme between 2013 and 2016. In general, SRCB has been a very fragmented field of study, however in the last three years, it has developed into a distinct entity; in the past, it was basically addressed through CSR. The most productive thematic areas during the last 30 years have been: (a) Research into consumer attitude, (b) research on CSR, and (c) research on social and sustainable consumption behavior. In response to calls for greater theoretical clarification of the SRCB discipline, the authors providing experts and novices with a better understanding of the current state of the art and suggest future research directions.

A Bibliometric Analysis of Sports Tourism and Sustainability (2002–2019)

Sports tourism is a relatively recent type of tourism, which has grown significantly in recent times. Not all effects of tourism are positive, so the analysis of its sustainability has particular relevance; especially since the publication of the 17 United Nations Sustainable Development Goals (SDGs) in 2015. The growing concern about tourism and sustainability makes it essential to examine how scientific research has adapted to new realities. This paper uses bibliometric techniques to investigate research trends related to sports tourism and sustainability. VOSviewer and SciMAT software were used. A total of 214 articles from Web of Science (WoS) indexed journals were analyzed. The results confirmed that interest in the study of these concepts has been growing, especially in the last four years. This is a comparatively new field of research (since 2002), so consolidated relations between thematic areas have yet to be observed, and there is a generally low concentration of authors and journals. Increases in several publications in this area are related to the celebration of mega sporting events or the publication of SDGs. The main contribution of this analysis lies in identifying important research issues, such as education and destination planning, which should continue to be addressed.

Scientific Performance and Mapping of the Term STEM in Education on the Web of Science

Technological progress is causing terms such as “STEM”, an acronym for Science, Technology, Engineering and Mathematics, to burst into the educational arena, marking a new era in the application of innovative and motivating teaching and learning processes. The objective of this research is to analyze the trajectory and the transcendence of the “STEM” concept in the educational field, having as reference the reported literature of Web of Science. The methodology applied in this research is based on bibliometrics, analyzing both the performance and the structural and dynamic development of the concept through a co-word analysis. The total number of documents analyzed is 4390. The results show that the scientific community mainly uses English and research papers to present their results. From 2015 onwards, the main lines of research are beginning to be established, which focus on “women” and “science”. It can be concluded that the term “STEM” in education is beginning to have a greater incidence and impact on the processes of teaching and learning, especially in the field of science, although there are currently discrepancies between men and women in its use.

Microalgae Water Bioremediation: Trends and Hot Topics

The need to reduce costs associated with the production of microalgae biomass has encouraged the coupling of process with wastewater treatment. Emerging pollutants in municipal, industrial, and agricultural wastewaters, ranging from pharmaceuticals to metals, endanger public health and natural resources. The use of microalgae has, in fact, been shown to be an efficient method in water-treatment processes and presents several advantages, such as carbon sequestration, and an opportunity to develop innovative bioproducts with applications to several industries. Using a bibliometric analysis software, SciMAT, a mapping of the research field was performed, analyzing the articles produced between 1981 and 2018, aiming to identifying the hot topics and trends studied until now. The application of microalgae on water bioremediation is an evolving research field that currently focuses on developing efficient and cost-effective treatments methods that also enable the production of add-value products, leading to a blue and circular economy.

What Is Going on with the Research into the Internationalization of Small and Medium-Sized Enterprises (SMEs)? An Intellectual Structure Analysis into the State-of-the-Art (1990–2018)

The internationalization of Small and Medium-sized Enterprises (SMEs) is a topic of constant research interest due to the impact these have on economic growth and employment in developed, emerging and developing countries. A desire to understand and a growing interest in the study of the internationalization process of SMEs has provoked a significant increase in the production of manuscripts in this field in the last decade. Therefore, it is necessary to carry out periodic reviews on the state-of-the-art of this phenomenon in order to highlight advances and limitations, to motivate reflections and stimulate progress in future research. Thus, the main objective of this study is to describe the state-of-the-art of the research into SME Internationalization based on a bibliometric analysis of 1152 manuscripts published from 1990 to 2018. The results enable the identification of the main agents that are constantly developing this field through an analysis of scientific production and collaboration indicators. Furthermore, through a co-word analysis, this research establishes hot-spot research trends that need to be developed in future research. The main contribution of this research is the configuration of a knowledge map on SME Internationalization research.

Mapping the Link between Corporate Social Responsibility (CSR) and Human Resource Management (HRM): How Is This Relationship Measured?

Despite the relevance of human resources in the management of Corporate Social Responsibility (CSR), confusion and theoretical chaos are still evident in the area. This manuscript provides a systematic review of the link between CSR and Human Resource Management (HRM), stressing the main topics along with the evolution and tendencies founded in this field. SciMAT was used to conduct a conceptual science mapping analysis based on co-word bibliographic networks. From 2006 to 2019, 194 documents were retrieved from the Web of Science. Considering the last period (2017–2019), the motor themes (those which are well-developed and relevant for the structure of the research field) were environmental management (including green HRM), sustainable HRM and pro-environmental behaviour. Socially responsible HRM (SR-HRM) was a basic theme (important, although not developed). Perceived organisational support was a specialised theme (well-developed, although less important), and employee commitment was an emerging theme (both weakly developed and marginal). In addition, a review of the measurement tools used in the main topics extracted from the previous analysis was carried out. Our analysis will help inform researchers and practitioners on the future of CSR and HRM and the previous efforts in the creation of measurement instruments.

Corporate Social Responsibility and Human Resource Management: Towards Sustainable Business Organizations

Today’s organizations are immersed in a global market, where any detail can provide a competitive advantage over rival companies and condition their sustainability. Corporate Social Responsibility and Human Resource Management have become very powerful tools within companies. However, the potential, development, and measurement of Corporate Social Responsibility (CSR) and Human Resource Management (HRM) have not been sufficiently explored. The literature has developed multiple case studies on CSR and HRM and has studied the combination of both factors and their link to economic, environmental, and social sustainability, but has not yet found a solid basis from which to address the new functionality of CSR, HRM, and sustainable business management. This work aims to investigate trends in scientific production related to Corporate Social Responsibility and Human Resource Management. Bibliometric techniques and SciMAT software have been used for this purpose. A total of 314 articles from Web of Science (WOS) indexed journals were analyzed. The results obtained confirm that the interest in the study of these concepts has grown exponentially in the last decade. It should be noted that the definitions of CSR and HRM, and even the relationship between the two, continue to be subject to multiple interpretations. The contribution of this work lies in the fact that, through the longitudinal analysis carried out, light is shed on the groups of issues that emerge with special projection, such as green-management, stakeholders, commitment, competitive-advantage, satisfaction, performance, sustainability, or research-methods-analysis, and which must continue to be explored in order to respond to the demands that business organizations have in this respect, and to help the total integration of the different approaches related to CSR and HRM.

Confronting the anomaly: directions in (German) economic research after the crisis

Recurring economic crises, like the one of 2007-2008, led to criticism of economic research and a demand to develop new strategies to avoid them. Standard economic theories use conventional approaches to deal with economic challenges, heterodox theories try to develop alternatives with which to face them. It remains unclear whether the 2007-2008 crisis led to a change in economic research as well as to a consideration of alternative approaches. We used co-word analysis to map the structure of economic research in Germany between 2005 and 2014. Core topics within economic research, such as "market" or "production" hardly shift and can be linked to standard economic theories. Peripheral topics such as "inequality" or "unemployment" show greater dynamics. However, only a few of these topics can be linked to heterodox approaches. Certain changes have occurred in reaction to the 2007-2008 crisis. However, the unchanged importance of standard economic topics raises the question whether these changes are sufficient to face coming economic challenges.

Productive, Structural and Dynamic Study of the Concept of Sustainability in the Educational Field

Sustainable education is currently booming in the teaching and learning processes, although it is not without complexity, due to its various dimensions and the evolution it has undergone to date. The objective of this research is to establish a mapping and scientific evolution of the term “sustainability” in education in the Web of Science database. To do so, a bibliometrical method has been applied, through the analysis of the performance of the scientific production and the evolution of the structure and dynamism of sustainability in education, by means of an analysis of co-words. The total number of references analyzed, after following a debugging process, was 9441. The results show the boom of sustainability in education in recent times, with a great impact on research related to attitudes and sustainability. It can be concluded that a large part of the studies analyzed are of a descriptive nature, with a decrease in the number of exploratory studies, which can give a holistic vision to the subject matter presented, especially regarding the development of the curriculum and the teaching-learning process.
