Diferencias de género en la producción científica de la educación en América Latina

Understanding the dynamics of research production and collaboration may reveal better strategies for scientific careers, academic institutions, and funding agencies. Here we propose the use of a large and multidisciplinary database of scientific curricula in Brazil, namely, the Lattes Platform, to study patterns of scientific production and collaboration. Detailed information about publications and researchers is available in this database. Individual curricula are submitted by the researchers themselves so that coauthorship is unambiguous. Researchers can be evaluated by scientific productivity, geographical location and field of expertise. Our results show that the collaboration network is growing exponentially for the last three decades, with a distribution of number of collaborators per researcher that approaches a power-law as the network gets older. Moreover, both the distributions of number of collaborators and production per researcher obey power-law behaviors, regardless of the geographical location or field, suggesting that the same universal mechanism might be responsible for network growth and productivity. We also show that the collaboration network under investigation displays a typical assortative mixing behavior, where teeming researchers (i.e., with high degree) tend to collaborate with others alike.

Systematic analysis of the scientific literature on population surveillance

Doctoral studies play a vital role in socializing young individuals in science as they navigate the challenges of modern knowledge-based societies. Taking various forms and intensities, the mentor–mentee relationship is integral to this process. The paper therefore addresses the temporal patterns of scientific collaboration between mentors and mentees, as well as among co-mentors, given that understanding the characteristics of mentoring collaborations is essential for developing successful higher education strategies for attracting potential doctoral students and designing effective science policies. Patterns of collaboration were identified using a symbolic data clustering approach and described using linear discriminant analysis. The data come from national information systems in Slovenia and cover the period between 1991 and 2020. On the mentor–mentee level, six types of scientific collaborations were identified and classified in three broader categories: study-limited, already established, and born and raised. The most common, born and raised, is characterized by students who are isolated from the scientific community at the beginning of their studies and have become well integrated into the scientific community and highly productive researchers by the time they complete their doctoral studies. The study-limited collaboration pattern is becoming increasingly popular and more common in the natural and technical sciences. The already established is more common among older mentees. The notion that mentoring promotes long-term scientific collaboration between mentors is not confirmed by the presented study. However, higher levels of collaboration between mentors are associated with younger age, working in the same scientific discipline, and younger mentors.

The field of transplant research has long been recognized for its innovative approaches and international collaborations. This study aims to dissect the landscape of global collaborations within transplant research during a past decade. Through a comprehensive bibliometric and network analysis of 5 high-impact factor transplantation journals from 2012 to 2021, we evaluated scientific production and collaboration patterns in 9 250 articles. International, national, and single-institution collaboration types were analyzed, using coauthorship as a measure of scientific collaboration. The data set revealed 40 622 authors from 2 094 institutions across 94 countries, with a marked increase in international collaborations during the past decade. The United States and Western European countries emerged as central nodes in the global network, facilitating the majority of collaborative efforts. Only 2.2% of potential institutional collaborations were explored during the decade. We found a lower chance of citations for single-institution research over time. Low- and middle-income countries were underrepresented in high-impact transplant research. The findings underscore the necessity of fostering inclusive, equitable research collaborations that bridge the gap between high-income countries and low- and middle-income countries, limiting their contributions to advancing global patient care. Practical recommendations for enhancing global collaboration in transplant research include facilitating academic exchanges, equitable collaboration practices, and increased funding opportunities. This study calls for a strategic shift toward a more inclusive and integrated global research landscape, aiming to advance transplant research and patient care universally. Addressing these disparities could lead to a more integrated global research landscape, benefiting transplant research and patient care universally.

The major role of toxicology societies in global collaborations – a call to action

The role of scientific collaboration in academic research has rocketed across the natural and social sciences. While the causes, consequences, and social interaction patterns of scientific collaboration have been well‐established, extant empirical work focuses on entire disciplines. In this paper, we study patterns of interdisciplinary scientific collaboration using the example of research on mergers and acquisitions (M&A), a phenomenon which calls for input from numerous disciplines. We base our findings on a social network analysis of co‐authorship practices in 687 co‐authored papers written by 1,158 authors, published in 30 leading journals and a book series in the 1951–2014 period. We find that scientific collaboration has increased in the M&A scholarly community since the 1990s, and that one third of co‐authorships are interdisciplinary. Collaboration is however not equally spread, but led by a minority of active scholars and certain disciplines. Recently, sub‐groups of authors have become mutually connected, pointing towards the emergence of an interdisciplinary meta‐level community. Our findings contribute to appreciating interdisciplinary collaboration practices in academic research and document the evolution of M&A research.

Background:Scientific collaboration is among the most important subjects in scientometrics, and many studies have investigated this concept to this day. The goal of the current study is investigation of scientific collaboration and co-authorship patterns of researchers in the field of library and information science in Iran between years 2005 and 2009.Materials and Methods:The current study uses scientometrics method. The statistical population consists of 942 documents published in Iranian library and information science journals between years 2005 and 2009. Collaboration coefficient, collaboration index (CI), and degree of collaboration (DC) were used for data analysis.Findings:The findings showed that among 942 investigated documents, 506 documents (53.70%) was created by one individual researcher and 436 documents (46.30%) were the result of collaboration between two or more researchers. Also, the highest rank of different authorship patterns belonged to National Journal of Librarianship and Information Organization (code H).Conclusion:The average collaboration coefficient for the library and information science researchers in the investigated time frame was 0.23. The closer this coefficient is to 1, the higher is the level of collaboration between authors, and a coefficient near zero shows a tendency to prefer individual articles. The highest collaboration index with an average of 1.92 authors per paper was seen in year 1388. The five year collaboration index in library and information science in Iran was 1.58, and the average degree of collaboration between researchers in the investigated papers was 0.46, which shows that library and information science researchers have a tendency for co-authorship. However, the co-authorship had increased in recent years reaching its highest number in year 1388. The researchers’ collaboration coefficient also shows relative increase between years 1384 and 1388. National Journal of Librarianship and Information Organization has the highest rank among all the investigated journals based on collaboration coefficient, collaboration index (CI), and degree of collaboration (DC).

ObjectiveTo determine the presence of a gender gap in the scientific production among Peruvian physicians and analyze either gap is associated with the presence of observable factors or the presence of prejudices against female physicians.MethodsWe analyzed data from the National Survey of User Satisfaction in Health 2016, a nationally representative survey that collected information about medical professionals working in health institutions in Peru. The outcome of interest was the number of publications in indexed journals. We estimated the gender gap in scientific production using the Oaxaca-Blinder (OB) decomposition method.ResultsFrom the 2216 physicians surveyed, 252 reported published at least one article in an indexed journal. From physicians with scientific production, 37.7% were women. The analysis of OB decomposition showed a gap of 2.11 indexed publications, disfavoring female physicians (p<0.01). Likewise, the explained component was 1.36 publications, representing 64.5% of the total gap (p<0.05).ConclusionsThere is a gender gap in the number of publications in indexed journals among Peruvian physicians. This gap is mainly explained by observable factors, such as the years of medical practice, being an accredited researcher and being a professor.

Objective Nowadays, organizations and institutions evaluate their performance to ensure that they are taking the right steps towards their goals and missions. In this regard, universities and research institutes assess their success in achieving their goals by analyzing their scientific outputs and productions. This study aims to investigate the scientific productions and collaborations of the authors affiliated with the University of Social Welfare and Rehabilitation Sciences (USWRS) in Scopus database in comparison with five medical universities. Materials &amp; Methods This study, using scientometric techniques, was conducted on June 5, 2021. The information about scientific productions of the USWRS and other five universities of Golestan University of Medical Sciences, Qazvin University of Medical Sciences, Semnan University of Medical Sciences, Hamedan University of Medical Sciences, Zanjan University of Medical Sciences were identified were extracted from the Scopus database and then converted into scalable format in Sci2 software. The output was then plotted in VOSviewer software. Results The mean number of authors for the USWRS in each article was 9, and the highest scientific collaborations was with the authors from United States, United Kingdom and Sweden. The authors for the USWRS also had a significant co-authorship with each other. According to the national ranking, this university was ranked 23 lower than Hamedan University of Medical Sciences and Golestan University of Medical Sciences. In terms of the number of published papers, it was in the second place after Hamadan University of Medical Sciences. The level of international cooperation of this university was more than other compared universities. Conclusion It seems that the USWRS’s scientific policy has been successful in increasing the scientific productions. More efforts should be made in this university to establish scientific collaborations with other universities at the national and international levels for encouraging authors.

Bibliometric analysis is a quantitative method used to measure and analyze scientific literature. This technique involves the collection and analysis of publication data, such as journal articles, books, and conferences, to evaluate and understand patterns of scientific communication, research productivity, author collaboration, journal impact, and trends within a scientific field. Bibliometric analysis has a limitation in that it is challenging to visualize effectively, necessitating the use of software for proper visualization. Therefore, this article discusses bibliometric analysis on spline regression for trend mapping and strategy development using VOSviewer software. The research results show that the visualization of spline regression keywords with VOSviewer can help in understanding patterns of relationships between variables, research trends, and network structures in scientific literature. Based on the analysis results, bibliometric analysis on spline regression can be visualized in trend mapping, which can aid in planning further research strategies, including identifying collaboration opportunities and underexplored research areas.
