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.

Abstract

Background and Study Aim: The aim of the study is to assess the development of scientific production and to map thematic coverage of research in physical education. The research process is focused on the following study questions: (1) how has the research productivity developed in the physical education research field?, (2) who are the main contributors (countries, universities, authors, source titles) to the amassing research output in the field?, (3) what are the leading thematic areas attracting the most attention of the academia?, (4) what are the emerging topics in the research field? Material and Methods: The Scopus database was used as a source of bibliometric data for the research sampling process. The research sample (N=9,224) consisted of the publications including the phrase ‘physical education’ in their titles. In order to achieve the aim of the study, we employed bibliometric methods i.e. research profiling and keywords co-occurrence analysis. We conducted general publication profiling to assess the trends in scientific production and to recognize leading contributors to the research field. We applied keywords co-occurrence analysis in order to identify and explore major thematic areas as well as emerging topics within the research field. VOSviewer software was used to support the analysis process and visualize the findings. Results: The study shows that physical education is a well-established research field with a long tradition. In the 2010s, it has received an increasing attention of academia which resulted in breakthrough growth in the number of publications indexed in Scopus. The amassing research output is distributed over 26 subject areas. Social Sciences, Medicine and Health Professions are the subject areas grouping the highest number of publications. The leading contributors to the research field are: the most productive country – the United States, the most productive research institution – Loughborough University, the United Kingdom, the most prolific author – David Kirk from the University of Strathclyde, the United Kingdom, the first choice source title – Teoriya i Praktika Fizicheskoy Kultury. Within the physical education research field, there are identified five leading thematic clusters related to: (1) physical education didactics, (2) physical activity of school pupils, (3) physical education of adolescents, (4) human motor competence, (5) physical activity of adults. Emerging topics include the following issues: (1) physical education teachers and their training/education, (2) physical education in the tertiary education context, (3) physical education in the secondary education context. Conclusions: The study contributes to better understanding of development patterns in research on physical education. It provides an added value for managing information on scientific productivity in the research field. Through discovering leading thematic areas and emerging topics within the research field, the study points out the issues important both for further research and development of theory as well as for educational and business practice.

The dynamic growth in the use of cloud computing systems results in increasing energy consumption. Consequently, more and more attention is given to energy efficiency issues both in research and theory development as well as the business practice of cloud computing systems. In spite of the rapid development of research, the field has not been mapped from the bibliometric perspective yet. This study aims at publication profiling and mapping the thematic structure of the cloud computing energy efficiency research field. Detailed research objectives include: (1) profiling scientific publications in the field, (2) identifying and exploring thematic research areas, (3) identifying emerging topics and discussing their potential as future research lines. The aforementioned objectives are translated into the following study questions: (1) What are the most productive nations, institutions, source titles, and scholars contributing to research on energy efficiency in cloud computing? (2) What does the thematic structure of the research field look like? (3) What are the “hot” research topics attracting scholars’ attention? The research methodology toolbox includes a combination of bibliometric descriptive studies (research profiling), science mapping (keyword co-occurrence analysis), and literature reviews (systematic literature review). Bibliometric data for analysis were elicited from the Scopus database. The VOSviewer software supported bibliometric analysis and data visualization.

Background. Organizational ambidexterity is listed among up-to-date concepts recommended for managers to cope with turbulence and multidimensionality of the business environment. The idea of combining both evolutionary and revolutionary organizational changes seems to be very attractive but challenging to implement. Although it has been widely discussed in the management-related literature for more than twenty years, it has not been explored thoroughly and it still remains an interesting topic for further research. Research aims. The aim of the paper is to analyze the literature contribution to the development of the ambidextrous organization concept as well as to identify the key problems and trends in research output. The research process is oriented to responding to the following questions: (1) What are the key contributions of the literature in the field to the development of the concept? (2) What are the key research topics and trends in the field? Methodology. Systematic literature survey is the applied methodology. The Scopus database is used as a source for the sampling process. Key findings. The analysis points out the following main areas of research interest in the field: (1) ambidexterity and ambidextrous organization conceptualization, (2) organizational management context (including managers) where these assumptions are embedded and studied, (3) innovations, organizational learning processes and creativity, and (4) strategic management aspects.
