Numerous studies have been conducted to investigate the impact of microplastics on soil eco-system, yet little attention has been given to the specific effects of mulch microplastics and the leaching of plastic additives from mulch films. This review inspects the propensity of commonly used plastic additives in mulch films, such as Di(2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and benzophenones (BPs), to migrate into soils and pose potential risks to soil biota. Further, we highlight the degradation of non-biodegradable plastic mulch films over time, which leads to an increase in the release of plastic additives and microplastics into agricultural soils. DEHP has been detected in high concentrations for example 25.2 mg/kg in agricultural soils, indicating a potential risk of uptake, translocation and accumulation in plants, ultimately altering soil physicochemical properties and affecting soil microflora and invertebrates. The review also explores how exposure to ultraviolet (UV) radiation and microbial activities accelerates the weathering of mulch films. Moreover, the resultant plastic additives and mulch microplastics can lead to genotoxicity and growth inhibition in earthworms (Eisenia fetida) and negatively impact the soil microbiome. Despite the significant implications, there has been a lack of comprehensive reviews comparing the effects of non-biodegradable mulch film additives on agricultural soil flora and fauna. Therefore, this review addresses the knowledge gaps providing a bibliometric analysis and eco-toxicological evaluation, discussing the challenges and future perspectives regarding mulch plastic additives and microplastics, thus offering a comprehensive understanding of their impact.

 

 

This study aimed to present an overview of the current status of research and important discoveries about immunotherapy for glomerulonephritis in general using bibliometric analysis. We collected the literature on immunotherapy for glomerulonephritis from the Web of Science (WOS) database for the last 10 years (2014-2024), and we assessed the mapping of knowledge using Citespace. The findings demonstrated that there were 258 articles concerning the immunotherapy for glomerulonephritis, with a faster growth after 2018. The USA, Charite Universitatsmedizin Berlin, and Anders, Hans-Joachim are the nation, organization, and writer with the highest number of publications. The most often cited reference is Rovin BH (2021) as well (5). The best partnerships are formed by prestigious universities and developed countries for glomerulonephritis research on immunotherapy. Three research hotspots in this area are rituximab, adjuvant, and antibody production erythematosus, respectively.

 

 

Objective: This study aimed to examine the global scientific output of research on patient delay and explore the hotspots and frontiers from 2000 to 2023 through bibliometric analysis. Methods: Publications regarding patient delay published from 2000 to 2023 were extracted from the Web of Science Core Collection (WOSCC). Subsequently, CiteSpace, VOSviewer, and Bibliometrix Online Analysis Platform were used to analyze publications, countries, institutions, authors, journals, and keywords. Results: A total of 721 papers were included in the study. The publication output increased from 20 papers in 2000 to 64 papers in 2023, a remarkable 220.00% growth. The USA (138 papers) and University of California San Francisco (21 papers) were identified as the most productive country and institution, respectively. Moser (10 papers), and Dracup (10 papers) are the most productive authors. “BMC Public Health” (24 publications) is the most productive journal. “Patient Delay” was the most cited keyword, with high-frequency keywords such as “Prehospital Delay”, “Symptoms”, “Time”, “Care”, “Diagnosis”, “Acute Myocardial-infarction”, and “Mortality” signaling hot topics in Patient Delay. Conclusion: There are increasingly many papers on patient delay. However, there has been limited development of cooperation between countries and institutions. In the future, collaboration between countries and institutions should be strengthened. In addition, 3 hotspots and 3 frontiers are summarized in this study to provide researchers with future research directions.

 

 

Sustainability issues constitute a distinct subdiscipline of librarianship and information science, with its own areas of study, methods, and areas of application. Despite being nearly 30 years old, there are still divergent opinions on its current phase of development and its links to other scientific disciplines. The authors aim to clarify and summarize the ongoing discussion through citation analysis, shedding light on the lifecycle of research papers in sustainability-oriented library and information science, the current research subjects of focus, the influence of subdomains within the discipline on other scientific areas, and the overall quantitative and qualitative landscape of the discipline. A detailed elucidation of the inquiry’s results is intended to outline the discipline’s cognitive structure and its impact on sustainability science. The lifecycle of disciplinary papers indicates the dynamic development of the field. Sustainability-oriented library and information science is well-established, and its research focus has already been consolidated. The optimal citation window for measuring the impact strength in this discipline is a period of 3 to 4 years. “Culture” and “Education” have been identified as the most forward-looking subdisciplines, whereas “Buildings” and “Collections” exhibit less dynamic growth. The social sustainability pillar is the dominant one, while the environmental pillar is slightly less prominent. The economic pillar is the least represented. Although the majority of information exchange occurs within the discipline, it maintains strong and numerous links with several other fields, including both technical and social sciences, as well as the humanities.

 

 

This article conducts a comprehensive analysis of specialization trends within and across fields of economics research. We collect data on 24,273 articles published between 1970 and 2016 in general research economics outlets and employ machine learning techniques to enrich the collected data. Results indicate that theory and econometric methods papers are becoming increasingly specialized, with a narrowing scope and steady or declining citations from outside economics and from other fields of economics research. Conversely, applied papers are covering a broader range of topics, receiving more extramural citations from fields like medicine, and psychology. Trends in applied theory articles are unclear.

 

 

Various bibliometric indicators have been used to assess the researchers’ impact, but composites of such indicators, namely a metric that combines various individual indicators to describe a complex construct, have received a strong critique thus far. We employ concepts from psychometrics to revisit a composite proposed by Ioannidis et al. (2020) that aimed to represent researcher impact. Based on a selected sample of highly cited researchers, our proof-of-concept study presents a psychometrically principled composite formation. Specifically, by relying on the congeneric measurement model (and related models) rooted in classical test theory, we found that one of the proposed indicators clearly violated the congeneric model’s fundamental assumption of unidimensionality, and two other indicators were excluded for redundancy. The resulting composite based on only three bibliometric indicators was found to display excellent reliability. Importantly, the reliability approached that of the composite based on five indicators, and it was clearly better than the original six-indicator composite. Further, we found rather homogeneous effective weights (i.e., relative contributions of each indicator to composite variance) for simple sum scores, and these weights were close to those calculated using an algorithm for equally effective weights. While the congeneric measurement model also showed strong measurement invariance across sexes, this model’s loadings and intercepts were not measurement invariant across scientific fields and academic age groups. Notably, we found that various derived composites correlate positively with academic age, hinting at a lack of fairness of the composites.

 

 

The inadequacy of internal control systems in certain universities often results in non-compliance with regulations, posing financial and legal risks for these institutions. This study aims to analyze trend research and identify the factors contributing to the internal control systems for regulatory compliance within universities. Employing bibliometric analysis, the approach entails utilizing R Studio software to construct patterns and trends in scientific literature concerning internal control within the university context. The bibliometric analyses involve gathering data from scientific databases and utilizing techniques such as co-occurrence network analysis mapping, citation analysis, and exploring the relationship between key topics and their impact on the field of study. The time periods in 1973–2024 research on internal control has evolved thematically, leading to a comprehensive examination, enhanced understanding, and adaptation to new difficulties. This research indicates that the connections among accounting, internal controls, internal audit, auditing, management control system, information management, societies and institution are crucial for providing effective internal controls at universities about regulatory compliance.

 

 

Today, academics and researchers constantly strive to achieve more in their respective fields. Their achievements are measured mainly by how many publications they have within publication venues and their work’s recognition (impact), which is usually determined through its citations, subsequently affecting how funding and awards are obtained. To assess the importance academics place on citations when evaluating scientists for recruitment or promotion, the authors of surveyed faculty members from the top 10 ranked universities globally. Their findings indicate that the majority of faculty members take citation counts into account when assessing candidates, which is reflected at a local and national level. The availability of huge curated bibliographic databases such as Elsevier Scopus and Web of Science (WoS) over the past twenty years has led decision-makers involved in promotions, funding, and strategic direction to increasingly request data related to individual studies or scholars (such as scientific articles, PhD students, postdoctoral researchers, and faculty members) as well as groups of individuals and articles (such as journals, universities, institutions, and companies) to support their decisions. Publication practices in the fields of social sciences and humanities differ from those used for most natural science publications. Consequently, their research output is often inadequately represented in the aforementioned journal-based databases typically used for bibliometric analysis. This issue is particularly pronounced for non-English journals, which are notably underrepresented, as well as for conference papers, books, and edited volumes. An alternative to the more traditional journal-based systems of WoS and Scopus is Google Scholar (hereafter referred to as GS), which is one of the most comprehensive databases currently available. Several works, e.g., have analyzed the relative coverage between Google Scholar and Scopus. As soon as scientists realized that a significant proportion of their evaluation was based on these purely quantitative methods, some started to take advantage of the system. At first, the prevalence of plagiarism was sparse. However, many members of the academic community soon began consistently striving to optimize their performance through two key approaches: (a) increasing the number of papers they have authored and (b) increasing their impact, i.e., the number of citations received by these papers. While it is of course acceptable for a scientist to increase their productivity and the quality of their research impact to attract more citations, several malpractices started making their appearance in the academic landscape. Some malpractices used to optimize authorship include buying authorship and generating large authorship lists by merging and splitting articles. Some of the malpractices used to optimize impact include the use of excessive self-citations, citation circles, and coercive citations, as well as uploading fake documents, editorial grouping, and using Generative AI tools. Most of these malpractices are easily achievable in Google Scholar since it is editable by the end user, but some, such as self-citations, citation circles, and coercive citations, are also a problem for curated bibliographic databases. Additionally, quality control issues in Google Scholar exacerbate the situation. In the remainder of this editorial, we will briefly describe the mechanisms behind these malpractices and provide some ideas for reducing the problem.

 

 

The study of vertebrate palaeontology in the United Kingdom holds a significant position in global research. This study conducts a comprehensive bibliometric analysis and topic modelling of UK vertebrate palaeontology from 2014 to 2023, utilizing data from the DeepBone database and Web of Science. A total of 2884 publications were analysed using bibliometric methods and Latent Dirichlet Allocation (LDA) to identify key research themes, institutional contributions, and international collaborations. The results reveal a significant increase in publication volume over the decade, peaking in 2021 with 374 papers. High-impact journals such as Nature and Science published approximately 6.60% of the total papers. The LDA analysis identified seven primary research themes, including morphology, palaeoanthropology, evolutionary biology, and geological periods. The Natural History Museum, University of Bristol, and University of Oxford emerged as major contributing institutions. Scientists from the United States were found to be the most frequent international collaborator. The average impact factor of the top journals in the field was 8.28 in 2024, highlighting the high quality of UK vertebrate palaeontology research. This study provides objective insights into the current state of vertebrate palaeontology in the UK, emphasizing its multidisciplinary nature, the importance of international cooperation in the field.

 

 

El Consejo Nacional de Humanidades, Ciencias y Tecnologías (CONAHCYT) de México ha solicitado recientemente a los miembros Sistema Nacional de Investigadoras e Investigadores (SNII), que también regula este consejo, que realicen actividades de Acceso Universal al Conocimiento (AUC) para tener el derecho de ingresar, mantenerse o ascender en este sistema nacional. Sin embargo, no existe una definición precisa respecto a qué es el AUC. Dicha indefinición ha provocado incertidumbre entre los miembros del SNII, quienes continúan realizando divulgación de la ciencia, sin saber si eso es lo mismo que el AUC. Se realizó una revisión sistemática de la literatura especializada en modelos de divulgación de la ciencia para conocer los modelos vigentes más relevantes. Se revisaron artículos de investigación en cuatro bases de datos científicos. Los hallazgos sugieren que puede proponerse un modelo de divulgación científica que contribuya a la definición del término Acceso Universal al Conocimiento.
