Determine the bibliometric characteristics of scientific articles that address the subject of neurosurgery in Latin America and the Caribbean. A bibliographic search of original articles published in the Web of Science database up to 2021 was performed, without language restrictions. The terms included in the search strategy were Neurosurgery, neurosurgical procedures, and neurological surgical procedure. Articles according to the inclusion criteria in the Rayyan application were included. Subsequently, a quantitative bibliometric analysis was carried out with the bibliometrix package in R and VOSviewer. We identified 882 articles published in 271 journals. The first publication was in 2006, the highest number of publications was in 2021, the annual percentage growth rate was 25.9, and the average number of citations per document was 11.2. The author with the highest number of publications was Teixeira MJ (41 articles), and the University of Sao Paulo had the highest number of articles on this topic. WORLD NEUROSURGERY was the journal with the most publications (120 articles), and the study by Carney et al (2017) was the most cited (1175 citations). The country of corresponding authors with the most publications and the greatest number of total citations was Brazil. Surgery, and Management were the most used keywords plus; however, in the most recent articles Simulation and Guidelines were used. In the past decade, there has been an increase in articles on neurosurgery in Latin America and the Caribbean. Scientific production in neurosurgery must continue to increase in order to promote evidence-based medicine. [ABSTRACT FROM AUTHOR]

The bibliometric study of scientific production in the field of education that has been carried out in Ibero-American countries between 2000 and 2020 and indexed in the Social Sciences Citation Index (SSCI) database of the Web of Science (WoS) is presented. 4786 documents have been analyzed using bibliometric techniques, finding a considerable increase in scientific production, with Brazil being the country with the highest production. Likewise, the distribution of the magazines in Bradford zones was determined, noting that the core is made up of two journals, the first published in Latin America and the second in Spain. There was evidence of a decline in single authorship in documents and an increase in international collaboration, reaching in 2000 percentages like those of national collaboration. Through this study, production patterns and trends have been identified, as well as the main channels for disseminating research in the field of education in Ibero-America. [ABSTRACT FROM AUTHOR]

The production of data sources has increased in recent years and making their treatment, retrieval and use operational becomes a challenge and a strategic differential for the nations that have this domain. Knowledge about Artificial Intelligence has been crucial for data processing and use, being considered decisive for economic and social development. This work aimed to survey research on Artificial Intelligence in Brazil. A comprehensive search expression was created, and related articles were obtained for the period 2011-2020 in the Web of Science database. Using bibliometric methods, the obtained records were analyzed using the software VantagePoint, VOSViewer, and Excel. An analysis was carried out regarding the participation of Brazilian research in relation to the world, the main Artificial Intelligence research institutions in the country, the main research topics, and the most active authors. Keyword cooccurrence networks, the collaboration between institutions and between authors were built. It was found that Brazil has a peripheral but increasing participation in relation to publications and that public institutions have a fundamental role in this production despite regional discrepancies, which could help in the development of public policies for technological inclusion.

Objective. To synthesize the findings on correlates of physical activity (PA) and sedentary behavior (SB) in South American children. Method. A search was carried out from June 24 to October 27, 2020, in the LILACS, PubMed, SciELO, Scopus and Web of Science databases. To broaden the search, the references of identified review articles were examined, and a panel of experts was surveyed. Observational and interventional studies conducted with South-American children from zero to 5 years of age were included. Results. Of 3 111 articles initially identified, 18 were eligible: 14 observational studies, 12 studies conducted in Brazil, and 17 studies investigating preschool children (3 to 5 years of age). In addition to Brazil, only Chile and Ecuador were represented. PA and SB were measured by accelerometers in seven studies; however, high variability was observed in the instruments and cut-off points used. Although children were classified as physically active in 12 studies, six studies showed that they spent considerable time in SB. Most studies assessed the individual (14 studies) and interpersonal (11 studies) domains, followed by the environmental (eight studies) and political (one study) domains. Interventions in the school context (four studies) increased PA levels and reduced the time spent in SB. However, the evidence from cross-sectional and interventional studies presented a high risk of bias. Conclusions. Given the knowledge gap identified in this review, studies with robust designs, covering additional South American countries are warranted, focusing on infants and children under 3 years of age and investigating correlates in the environmental and political domains.

An overview of insect galls on Asteraceae in Brazil is presented. We used the Web of Science database to find publications about insect galls from 1988 to 2020. We analyzed 88 publications and collected data from 51 of those. A total of 487 gall morphotypes were counted on 157 plant species of 42 genera. This value singled out Asteraceae as the richest plant family in number of gall morphotypes in Brazil. Most morphotypes were recorded in the Atlantic Forest (41%) and Cerrado (30.5%), the most surveyed biomes in Brazil. Baccharis L. supported the greatest gall richness (43.9%), which could be explained by the hypotheses of geographic area and taxon size. Baccharis concinna G.M. Barroso, B. dracunculifolia DC. and B. platypoda DC. were indicated as superhost species. Most galls were induced on stems (52.2%), a pattern known in Asteraceae for gall-inducing Tephritidae and Chloropidae, and extended in the present study to Cecidomyiidae. Most galls were fusiform (42.5%), which can be related to the highest number of gall on stems. Cecidomyiidae (Diptera) were the most frequent inducers, as observed worldwide. The presence of other dwellers - parasitoids, cecidophages, kleptoparasites, and successors - were reported in 8.8% of the gall morphotypes, being parasitoids the most frequent, as found in other Brazilian publications. Most host plants (58%) are endemic to Brazil, 14% are useful and few are vulnerable or endangered (six and four species, respectively). Due to the high host specificity, the gall-inducers associated with these plants can also be considered either endemic, important, vulnerable and/or endangered, respectively. [ABSTRACT FROM AUTHOR]

Cotton (Gossypium hirsutum L.) belongs to the malvaceas family and is grown in all regions of Brazil. According to data from the Brazilian Association of Cotton Producers, Brazil occupies 4th place in the ranking of cotton production according to the 18/19 harvest. Because of this importance, this review aimed to carry out a bibliometric survey on cotton oil and flour and their applications. For this, a bibliometric analysis was carried out relating cotton, oil and flour in the Scopus and Web of Science databases in the years 1989-2019, and subsequently, the Web of Science data were analyzed using the VOSviewer program. The results showed that there were a total of 1525 research and reviews articles in the Scopus and Web of Science databases in the last three decades, and, based on the entire analysis, it was noticed that the studies of the last three decades are focused on separation area and biofuels, as well as that the Republic of China stands out among the most cited countries besides its universities. According to these results, it can be concluded that the Republic of China has a lot of influence in studies with cotton and more research is needed to use cotton and its derivatives in the food industry.

This article is part of an ongoing research. The research aims to analyze the national scientific production of Information Science, from 2010 to 2020, published in journals indexed in the Web of Science and Scopus databases. In order to achieve the general objective, the following specific objectives were chosen: Analyze the scientific production of teachers\researchers from postgraduate programs in Information Science; Identify the most important themes approached in the scientific production of graduate programs in Brazil; Identify the most productive authors of each postgraduate program; Check collaboration in the area; Survey the titles of the most productive journals in the studied period; Characterize the most productive programs. It is a descriptive research with quantitative and qualitative approaches. The quantitative approach will use bibliometric and scientometric techniques to assist in measuring the researcher's productivity. When the scientific production was surveyed from 2010 to 2020 in the Web of Science and Scopus databases, 3,000 articles and reviews were found. So as to identify the main themes addressed, it was chosen to identify the keywords and the relevance in the studied period. 1,093 authors were found in the Web of Science database and in the Scopus database 6,886 authors who produced 2,206 articles and reviews in the period from 2010 to 2020. When verifying the existing collaboration in the area of Information Science in the period 2010-2020, there is an expressive institutional collaboration in the total academic production. Institutional collaboration corresponds to 34% of academic production. To survey the most productive journals in the period studied, publications in 48 journals were found in both databases. To characterize the most productive programs, the following references were adopted: year of beginning of the programs, number of teachers of the programs, areas of concentration of the programs, the stricto sensu postgraduate modalities of each program, the evaluation by CAPES of the master's and doctorate and the regional location. It was noted that there is a concentration of programs in the Southeast region. [ABSTRACT FROM AUTHOR]

The genus Inga Mill. belongs to the mimosoid clade (Fabaceae, Caesalpinioideae) that includes 131 species in Brazil. It is the most important genus of Fabaceae. In this sense, this study aimed to perform a bibliometric analysis on Inga from Santa Catarina state. A survey of the published literature was conducted using the electronic databases of the Web of Science, Scopus and SciELO with the accepted names of Inga species and its synonyms. Papers were distributed in four subject categories: C1 (Ecological), C2 (morphology, anatomy, taxonomy, histology, physiology and genetics), C3 (production and use) and C4 (biochemical and nutritional properties). We registered 232 papers for 13 species of Inga. C1 was the most studied subject category, mainly in topics such as nutrient supply, shade and nitrogen fixing capacity. We also noticed that the subjects diversified over the years, with registered papers in all categories. Inga edulis, I. vera and I. marginata were the most registered species in our survey. Our results showed an increase in the number of articles on Inga over time, especially in the last 13 years. However, some important gaps need to be addressed, such as the relatively small number and/or lack of studies conducted for some species. [ABSTRACT FROM AUTHOR]

Brazilian karstology has been strengthened since the 1990s, resulting in scientific production gradually expanding into new areas studied and deepening the knowledge of regions already studied. Thus, this study aims to carry out a scientometric analysis of the scientific output on karst in Brazil between 1990 and 2020, enabling the evaluation of the development and trends of studies in a given scientific field, in this case, Brazilian karstology. The methodological procedures adopted involve quantitative analysis of scientific production in the Web of Science databases, Capes Periodicals Portal and the Brazilian Digital Library of Theses and Dissertations. The studies' analysis shows an exponential increase in karst studies in Brazil, especially in the last decade. There is also a predominance of articles published in English. Geology and zoology were the most studied sub-areas of knowledge; however, studies produced in several other areas stand out. The Southeast region contributed the most to karst research in Brazil, mainly through the University of São Paulo and the Federal University of Minas Gerais. The analyzed works presented a tendency of studies related to the taxonomy of underground species and research related to the conservation of karst environments. Finally, Brazilian karstology presents itself as an interdisciplinary science. • Exponential increase in the study of karst in Brazil. • Geology and Zoology are the most studied areas in karst in Brazil. • Studies on karst in Brazil are concentrated in the Southeast.

In this study, we summarized the evolution of scientific research about fungus Phakopsora pachyrhizi Sydow & Sydow affecting soybean [Glycine max (L.) Merrill]. We retrieved research articles from the Thomson Reuters Web of Science database that reported studies of the Asian soybean rust (ASR) from 1945 to 2018. We applied the scientometric analysis of the temporal trends of authors, journals, research partnerships, and resistance genes to ASR. Several studies aiming to understand fungal etiology, testing, or improve strategies to control the pathogen were developed. The temporal trends in publications showed an increase in the number of publications between 2005 and 2013. This is directly related to the dissemination of ASR in South and later North America, which facilitates field research and an increase in grant opportunities. The USA had the highest number of published articles (42%), followed by Brazil, Germany, Japan, and Argentina. The leading organizations associated with these publications are from Brazil and the USA. 19% of articles pertaining to ASR were published in the journal Plant Disease. Our results also showed that among the seven dominant genes identified for resistance to ASR, Rpp1, and Rpp2 are the most studied. Several countries, institutions, and plant scientists are deeply involved in ASR research and have been making efforts to control this disease and ensure food security worldwide.
