The data were collected from Scopus. Both performance and science mapping analysis were performed.FindingsThe research results showed the top author, paper and country of ISO 50001 publications. There are four author collaboration clusters and five country collaboration clusters. Eight research themes were mapped into four quadrants based on the density and centrality. The bibliometric coupling analysis showed six research clusters. Finally, the research issues were mapped. The implications were discussed.Practical implicationsThis research gave several implications for researchers, practitioners and public policymakers. For researchers, the bibliometric analysis provides several research issues that can be followed up by future research. For practitioners, the bibliometric analysis showed that applied tools and methods that can assist the implementation of ISO 50001-based energy management have been developed. For public policymakers, the bibliometric analysis offered the knowledge structure on ISO 50001 that can be used in public policymaking development. The author collaboration cluster and the bibliometric coupling cluster can be used to trace the scientific information that is needed as the foundation of public policy.Originality/valueMany ISO 50001 studies have been performed. However, based on the search in several main academic scientific paper databases, there is no bibliometric study on the research topic. This is the first bibliometric study on ISO 50001 publication. This study takes a holistic approach combining performance analysis and science mapping analysis that includes elaborated thematic mapping and evolution analysis.

This paper addresses the effect of building orientation efficiency of the green facade in energy consumption, for which the case study is an urban block in Passeig de Gracia, L’Eixample, Barcelona. Nowadays, many countries are faced with the trouble of the deficiency of energy resources and the incapability of saving them. Most of this energy is consumed in the cooling, heating, and artificial ventilation of buildings. For this reason, the development of an integrated strategy like a green facade is essential to transform buildings into structures that consume less energy and to improve the occupants’ comfort conditions. From the perspective of the urban landscape, the green facade can influence the quality of life in cities due to its positive effects such as the purification of air, the absorption of carbon dioxide, and the mitigation of dust, as well as the aesthetic and psychological aspects. Such criteria are based on the adoption of suitable orientation for the green facade, which is the second layer of the facade in an office building with a curtain wall as the main facade. Since the most important factor in the implementation of a green facade is the building’s orientation, the optimum orientation could be the key factor in regards to the reduction of energy consumption and cost and the improvement of overall energy efficiency. We used software that helped simulate the total energy consumption, the cost, and the energy use intensity annually and monthly. Consequently, after testing was carried out, it was proven that a green facade as a second layer with a southeast and/or a southwest orientation results in the maximum energy saving in a coastal city with a Mediterranean climate like Barcelona.

Green facades, integrating vegetation into building envelopes, are a pivotal strategy for sustainable urban architecture, addressing challenges like urban heat islands, energy inefficiency, and biodiversity loss. This comprehensive review synthesizes global research, evaluating green facades’ environmental benefits, including thermal regulation, air quality improvement, and biodiversity enhancement, alongside their economic viability and social impacts. Through detailed case studies and performance analyses, the paper highlights their transformative role in sustainable green buildings and urban design. Challenges, such as high costs, maintenance demands, and climate adaptability, are critically assessed, alongside innovative technological and policy solutions to scale adoption. The findings underscore green facades as a cornerstone of environmentally responsible urban futures, aligning with global sustainability goals like the United Nations Sustainable Development Goals (SDGs).

Research trends and hotspots of ferroptosis in neurodegenerative diseases from 2013 to 2023: A bibliometrics study

Associations between the microbiome-gut-brain axis and dementia have attracted considerable attention in research literature. This study examined the microbiome-gut-brain axis and dementia-related research from a bibliometric perspective. A search for original research and review articles on the microbiome-gut-brain axis and dementia was conducted in the Web of Science Core Collection (WOSCC) database. The R package "bibliometrix" was used to collect information on countries, institutions, authors, journals, and keywords. VOSviewer software was used to visualize the co-occurrence network of keywords. Overall, 494 articles met the study inclusion criteria, with an average of 29.64 citations per article. Corresponding authors of published articles were mainly from China, the United States and Italy. Zhejiang University in China and Kyung Hee University in Korea were the most active institutions, while the Journal of Alzheimer's Disease and Nutrients published the most articles in this field. Expected main search terms, "Parkinson disease" and "chain fatty-acids" were high-frequency keywords that indicate current and future research directions in this field. This bibliometric study helped researchers to identify the key topics and trends in the microbiome-gut-brain axis and dementia-related research. High-frequency keywords identified in this study reflect current trends and possible future directions in this field related to methodologies, mechanisms and populations of interest.

This research reports the potential environmental benefits derived from an overall intervention of living skins [green roofs and green facades] in the city core of Vancouver, Canada. These include the reduction in cooling and heating demand; reduction in stormwater runoff; improvement of air quality; enrichment of urban biodiversity and urban agriculture; reduction in the urban heat island effect; the contribution to carbon neutral architecture; and an assessment of different construction systems. It analyses the environmental behaviour of the selected site by applying the Seattle Green Factor. The research focuses on the energy performance of a typical residential building within the selected area, through the Energy 10 simulation program. It also analyses the reduction in stormwater runoff through the Curve Number Method; as well as the reduction of CO2 emissions based on related research. Obtained data shows that the total energy used for cooling is reduced [100%] through the greening of roofs and facades, which means the 9% of the total energy demand by the studied building. It also shows that CO2 emissions would decrease by 9%; and stormwater runoff would be reduced by 4%. The research compares these findings with previous related research on green roofs, facades and urban forests. Its findings suggest that these types of “living skins” interventions achieve better environmental performance in warm-dry climates where cooling energy demand is greater.

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.

PurposeThis study aims to contribute to the relevant body of knowledge by examining the bibliometric studies related to tourism and hospitality indexed in the Web of Science (WoS) database from a bibliometric perspective (evaluative and relational techniques).Design/methodology/approachThe WoS database was used to obtain studies to be reviewed. A total of 136 studies were analyzed and visualized in terms of evaluative and relational techniques, and a subject categorization was made.Findings“Tourism management” and “tourism and hospitality” are the two fields of research where bibliometric studies are carried out more frequently. Evaluative techniques were used in most studies while relational techniques, such as co-word, co-author, co-citation analysis and bibliographic coupling, were performed less. Relational techniques indicate that the words “bibliometric analysis” and “tourism” are frequently used together in the studies examined; the most common authorship cooperation is between China and USA.Research limitations/implicationsThis study provides an overview of bibliometric studies in tourism and hospitality literature. It expands the previous literature and shows study topics that are more focused by examining the abstracts and contents of articles published in journals in different WoS categories.Practical implicationsFindings related to evaluative and relational techniques can serve as useful information for researchers, who are new to the field.Originality/valueThis study contributes to the current knowledge accumulation by its lack of year, country, region and language limits.

This study aimed to comprehensively review the collaboration and impact of countries, institutions, authors, and journals on the role of immunity in TNBC from a bibliometric perspective, evaluate the keyword co-occurrence of the knowledge structure, and identify hot trends and emerging topics. Articles and reviews related to immunity in TNBC were retrieved from the Web of Science core collection using subject search. A bibliometric study was conducted primarily using CiteSpace and VOSviewer. A total of 3,104 articles and reviews were included from January 1, 2014, through December 31, 2024. The number of articles on immunization in TNBC is rising. These publications are mainly from 415 institutions in 82 countries, led by China and the USA. Among these publications, Lajos Pusztai published the most papers, while Peter Schmid was co-cited the most. The most productive journals focused on molecular biology, biological immunology, and clinical medicine. Furthermore, co-citation analysis revealed that tumor microenvironment, biomarkers, and immune checkpoint inhibitors are current and developing research areas. The keywords “immunotherapy” and “nanoparticles” are also likely to be new trends and focal points for future research. This study adopted bibliometric and visualization methods to provide a comprehensive review of the research on immunization in TNBC. This article will help researchers better understand the dynamic evolution of the role of immunity in TNBC and identify areas for future research.

All scientific journals need to be regularly monitored and evaluated from a bibliometric perspective. The Journal of Artificial Societies and Social Simulation (JASSS) founded in 1998 is dedicated to the topics related to artificial societies and social simulation. It is a pioneering journal with the global audience and international authors. Bibliometric analysis of this journal can be helpful in evaluating its scientific performance and research quality. In this study, the number of JASSS papers, highly-cited papers, the most prolific authors, the most active research institutions and countries were identified and their keyword and term co-occurrences and journal and author co-citation maps were visualized in the period 2000-2018 by using various bibliometric indicators in VOSviewer bibliometric software package. The results showed that with a high contribution to the field and a scientific collaboration with other related journals, JASSS had found its way in the field of social simulation and achieved an academic level. This study provides a reference for future studies by exploring the knowledge structures and publishing trends of JASSS. The bibliometrics analysis and visualization of JASSS can be a useful for either library and information science (LIS) scholars or the people interested in bibliometric studies; therefore, they can use it as a pattern to review other journals. © 2019, Heidar Mokhtari, Azadeh Roumiyani, and Mohammad Karim Saberi.

This study contributes to the identification of sustainability literacy variables for language teaching in higher education. Prior studies have addressed sustainability literacy through curriculum development, environmental education, and technological adoption. Sustainability literacy ensures that higher education academics have sustainability knowledge, adopt and perform sustainable practices or attitudes. However, previous studies neglect how environment, economy, social variables of sustainability literacy are disseminated in language teaching. The language teaching has not addressed sustainability themes in language skill courses such as listening, speaking, reading, and writing. Thus, this study aims to generate sustainability literacy variables that can be used as sustainability themes in the language teaching. A bibliometric analysis through VOSviewer is employed to collect the variables from the Scopus database by determining keywords. The present study employs BOOLEAN search with some keywords including “sustainable literacy”, “sustainability literacy”, “environmental literacy”, “higher education”, “university”, “institute”. In addition, inclusion criteria include journal article as type document, English language, and open access. The 106 documents met the criteria ranging from 2008 to 2024. The results indicate that there are eight groups of sustainability themes related to sustainability literacy. Of the eight groups, sustainability literacy variables selected for the language teaching consist of climate change, energy efficiency, renewable energy, economic growth, digital economy, financial knowledge, global citizenship, and knowledge sharing. The variables give implications both in practice and theory. Keywords: Sustainability literacy; higher education; language teaching; VOSviewer.

BackgroundCancer is a global health issue, and as the side effects of conventional treatments become more noticeable, many patients turn to complementary therapies, especially traditional Chinese medicine exercises. These exercises help regulate the mind and body, enhance immune function, and alleviate side effects. Despite the potential of these treatments, bibliometric studies on this topic are limited.MethodsFor this study, we analyzed literature from the Web of Science Core Collection (WoSCC) from 2011 to 2024 and used VOSviewer (version 1.6.20) and CiteSpace (version 6.4.R1) to explore research trends, academic impact, collaboration networks, and keyword hotspots.ResultsA total of 261 articles from 2011 to 2024 were included, with the number of annual publications increasing from 2 to 37. China led with 144 articles and 2678 citations, followed by the U.S. with 83 articles and 3732 citations. The University of Hong Kong and Harvard Medical School were the top institutions. The key authors included Cheung Denise Shuk Ting and Takemura Naomi, each of whom published 8 papers. Integrative Cancer Therapies had the greatest impact. Keyword analysis revealed research hotspots such as “cancer rehabilitation”, “immune regulation”, “mind–body exercise”, and “psychological stress relief”.ConclusionThe application of Chinese medicine exercises in adjunctive cancer therapy is gradually becoming a popular research topic. Bibliometric analysis has revealed the development trends and frontier issues in this field, providing scientific evidence for future research directions. There is still great potential for further research, particularly in areas such as cancer immune regulation and psychological rehabilitation.
