Study of maize endophytes worldwide-analyzing and mapping by bibliometric approach

Leer artículo

 

 

No global summary of maize endophyte publication exists. It’s hard to elaborate on global data because the provided information is localized. This study examined maize endophyte research and its future insight. Six hundred-three papers related to the topic were downloaded from Scopus. Parameters were computed using Excel 2016, whereas bibliometric analysis used VOSviewer. Co-occurrence, co-authorship, and citation were the three primary types of analysis. Kolmogorov-Smirnov determined the author’s Lotka’s Law productivity. This study found that the cumulative number of publications followed a linear model from 1966 to 1991; however, later, the model followed an exponential curve. The most comprehensive research on maize endophytic topics is in Agricultural and Biological Sciences (34.3%). The US published 203 documents, followed by China and Brazil. The most published author is Bacon CW, who has published 23 papers. The distribution of the author’s productivity conforms to Lotka’s Law. The bibliometric map showed fungal, bacterial, and endophyte microbiology clusters. The result showed that the study on maize endophytic fungi was smaller than bacterial species. Bacillus sp. and Enterobacter sp. are the popular studied bacteria endophytes, while Beauveria bassiana dominates fungal. In addition, future research trends will concentrate on “fungi endophytes” and “effect on seed mycorrhiza.”

The issue of water resources is a perennial topic for achieving human sustainable development goals. Over the last decade, a renewed watershed governance regime, River Chief System emerged to solve the issue of river pollutions in China, and attracted attentions across the world. In this review article, we profiled River Chief System, including its origin, principle and characteristics, and found that the primary feature of River Chief System is its hierarchical structure and the implementation of responsibility. By triangulating bibliometric measurement of the Citespace tool, database of the Web of Science and the China National Knowledge Infrastructure, the development, research trends and hotspots of River Chief System research have been reviewed systematically. The number of publications of River Chief System is showing a significant growing trend, and their foci are diverse: water environmental effects, mechanisms of River Chief System, public participation and supervision and localization of River Chief System, and the implement of “One River, One Policy” plan. Finally, theoretical and practical suggestions for the future study of River Chief System are proposed. This review systematically introduces China’s experience on river management to the world, which is of great significance for the world to fully understand the River Chief System of China and further improve and promote it.

Citational politics in and through animal geographies: interrogating onto-epistemological diversity

Leer artículo

 

 

This paper contributes to geographic literature on the effects of inequity in citational practice and politics, focusing in particular on onto-epistemological diversity (or lack thereof) in animal geographies’ citational structures. Through a bibliometric analysis of journal articles in Anglophone animal geographies (as a subdiscipline of human geography), we examine the intersections between citational trends, the contours of knowledge in the field and everyday academic lives. Our goal in this paper is to highlight some of the ways in which citational inequities are fueled. Specifically, our analysis shows that within Anglophone animal geographies, citational esteem can accrue through institutional networks and shared onto-epistemologies, which often go along with ethical and political orientations that refrain from explicitly contesting the status-quo of anthropocentrism. We ground our analysis with a reflective discussion of everyday academic practice to understand the multi-scalar dynamics and implications of citational politics and prompt heightened reflexivity among geographers concerning how animal and other geographies are constructed and reproduced – and how these reproductions can be contested.

Leer artículo

 

 

Research on consumer ethnocentrism (CE) has increased worldwide in various academic disciplines and business sectors due to the rise of globalization and cross-border trade in goods and services. There are few studies that review the literature on CE, all of which can be improved in terms of their degree of objectivity, systematization and number of publications used. The main objective of this paper is to contribute to the academic literature on CE. A broad spectrum of 670 indexed articles from the union of WoS and Scopus was used. We use R and VOSviewer to process the data. We follow a methodological organization according to the 5 W + 2H review framework, the Scientific Procedures and Rationale for Systematic Reviews of the Literature (SPAR-4-SLR) protocol. A bibliometric analysis of keyword co-occurrence in conjunction with the Theory framework. Context, Characteristics and Methodology (TCCM). There is a growing trend in scientific production, with contributions from 82 countries, 1292 authors and 281 sources, with the United States leading the way, followed by Australia and India. The cognitive structure is made up of topics such as consumer ethnocentrism, country of origin, marketing strategies, branding, consumer behavior in marketing, consumer attitude, and consumer animosity. This work provides an objective and scientifically rigorous basis for reducing researcher bias in literature reviews. In addition, it improves the formulation of marketing and commerce strategies by business or public policy decision-makers. The implications and limitations of the study are presented, and future lines of research are suggested.

One hundred years of Ecuadorian biomedical scientific output and its association with the main causes of mortality: a bibliometric study

Leer artículo

 

 

Introduction: Historically, low-and middle-income countries have been scarce producers of biomedical research; only 2% of the global scientific output is produced by these countries despite accounting for 92% of the global burden of disease. In addition, few low-and middle-income countries have exhaustively mapped and analyzed their scientific production in health and its association with main local burden of disease. Objective: To evaluate the evolution of biomedical research in Ecuador over the last 100 years and its relationship with the main causes of mortality. Methods: A bibliometric study embedded in a systematic review design was carried out using biomedical publications indexed in Scopus and Web of Science (WoS) during the period 1920–2021. Information from the National Institute of Statistics and Census was used to identify the main causes of mortality. Results: Our search strategy identified 16,697 publications related to biomedicine in Ecuador. Of these 3,225 articles met the criteria for this study. Since 2010, there has been an exponential increase in scientific production in biomedicine. This increase was predominantly based on cross-sectional observational studies (49.67%). During the period analyzed (1920–2021), biomedical production was distributed with 52.43% in clinical research, 37.79% in public health, and 9.77% in basic sciences. The research focus with the highest number of publications was epidemiology and surveillance system of diseases (23.44%). Additionally, private universities are the largest producers of biomedical research compared to public universities, 40.12% vs. 19.60%, respectively. Of the total biomedical research produced, 18.54% is associated with the main causes of mortality, and the Ecuadorian private university is the largest contributor to these studies compared to public universities, 39.97% vs. 16.72%. Conclusion: In one century, Ecuador produced 3,225 articles in biomedicine, according to our criteria. 18.54% of the total produced is aimed at solving the main causes of mortality in the country. Private universities are the leaders in scientific production related to health in Ecuador.

Bibliometric and scientometric analysis of PSMA-targeted radiotheranostics: knowledge mapping and global standing

Leer artículo

 

 

Purpose: Bibliometric and scientometric analyses provide a structured approach to large amounts of data, enabling the prediction of research theme trends over time, the detection of shifts in the boundaries of disciplines, and the identification of the most productive countries, institutions and scholars. In the context of prostate-specific membrane antigen (PSMA)-targeted radiotheranostics, no bibliometric or scientometric analysis has been published thus far. Therefore, this study was conducted to identify key contributors to the literature, assess the global scientific production of related research, and possibly predict future development patterns. Methods: Scientometrics and bibliometrics were utilized to analyze the current body of knowledge while tracking its evolution to support scientific decision-making comprehensively and systematically. Science mapping techniques were employed to visualize research activities. Two different tools, Tableau and VOSviewer, were utilized, with VOSviewer being deemed the most suitable for the research objectives. The Web of Science (WoS) was used as the principal database for the searches. Results: Through the search process over a period of 30 years (January 1993–January 2023), 694 original studies in the English language were subjected to comprehensive analysis. By employing bibliometric and scientometric methods, multiple networks were created that mapped various concepts, such as publication trends, leading countries, cocitations, coauthorship among researchers and scientists, as well as coauthorship among organizations and funding agencies. This study revealed the evolutionary patterns, trends, outliers, and key players in the PSMA field, which enabled a more nuanced understanding of the research landscape. Conclusion: This research contributes to the enrichment of knowledge on PSMA-targeted radiotheranostics through detailed global bibliometric and scientometric analyses. It stresses the necessity for the development of communication platforms, the establishment of supportive infrastructures, and the implementation of proactive solutions to address emerging challenges. This study offers a significant resource for delineating effective strategies and identifying prominent funding bodies essential for continuous advancements in the field of PSMA-based diagnosis and therapy for prostate cancer. It is vital to sustain this momentum to ensure further progress in this pioneering area.

Leer artículo

 

 

OBJECTIVE A sustainable neurosurgery workforce depends on robust training pipelines, but the size and distribution of the global neurosurgery trainee workforce has not been described. The objective of this study was to identify the types of training programs that exist in the global neurosurgery workforce, the support that trainees receive, the diversity of trainee experiences, and the accreditation processes that exist to regulate training programs. METHODS This study was a subanalysis of a cross-sectional survey administered online in all 193 countries and 26 territories, independent states, and disputed regions as defined by the World Bank and United Nations. Participants were identified through neurosurgery society leadership, the personal contacts of the coauthors, and bibliometric and search engine searches. Population-weighted statistics were constructed and segregated by country income level and WHO regions. RESULTS Data were obtained for 187 countries (96.9%) and 25 additional territories, states, and disputed regions (96.2%). There were an estimated 1261 training programs and 10,546 trainees within the regions sampled, representing a global pooled density of 0.14 neurosurgery trainees per 100,000 people and a median national density of 0.06 trainees per 100,000 people. There was a higher density in high-income countries (HICs; 0.48 trainees per 100,000 people) compared with upper-middle-income countries (0.09 per 100,000), lower-middle-income countries (0.06 per 100,000), and low-income countries (LICs; 0.07 per 100,000). The WHO European (0.36 per 100,000) and Americas (0.27 per 100,000) regions had the highest trainee densities, while the Southeast Asia (0.04 per 100,000) and African (0.05 per 100,000) regions had the lowest densities. Among countries with training programs, LICs had the poorest availability of subspecialty training and resources such as cadaver laboratories and conference stipends for trainees. Training program accreditation processes were more common in HICs (81.8%) than in low- and middle-income countries (LMICs; 69.2%) with training programs. CONCLUSIONS The authors estimate that there are at least 1261 neurosurgery training programs with 10,546 total trainees worldwide. The density of neurosurgery trainees was disproportionately higher in HICs than LMICs, and the WHO European and Americas regions had the highest trainee densities. The trainee workforce in LICs had the poorest access to subspecialty training and advanced resources.

Analyzing collaboration and impact: A bibliometric review of four highly published authors’ research profiles on collaborative maps

Leer artículo

 

 

The concept of impact beam plots (IBPs) has been introduced in academia as a means to profile individual researchers. Despite its potential, there has been a lack of comprehensive analysis that evaluates the research profiles of highly published authors through the lens of collaborative maps. This study introduces a novel approach, the rating scale for research profiles (RSRP), to create collaborative maps for prolific authors. The initial hypothesis posited that each of the research profiles would attain a grade A, necessitating empirical verification. This research employed collaborative maps to analyze the publication patterns of authors using the Web of Science database, focusing on co-authorship patterns and the impact of their scholarly work. The study relied on various bibliometric indicators, such as publication count, citation metrics, h-index, and co-authorship networks, to provide a detailed assessment of the contributions made by each author in their field. Additionally, authors’ IBPs were generated and assessed alongside collaborative maps, using a grading scale ranging from A (excellent) to F (lacking any articles as first or corresponding author). The analysis confirmed that all 4 research profiles achieved a grade A, with their centroids located in the third quadrant, indicating a high level of scholarly impact. The h-indexes for the authors were found to be 38, 51, 53, and 59, respectively. Notably, Dr Tseng from Taiwan showed a distinct pattern, with a significant number of solo-authored publications in the second quadrant, in contrast to the other 3 authors who demonstrated a greater emphasis on collaboration, as evidenced by their positioning in the first quadrant. The study successfully demonstrates that RSRP and IBPs can be effectively used to analyze and profile the research output of highly published authors through collaborative maps. The research confirms the initial hypothesis that all 4 profiles would achieve a grade A, indicating an excellent level of scholarly impact and a strong presence in their respective fields. The utility of collaborative maps can be applied to bibliometric indicators in assessing the contributions and impact of scholars in the academic community.
