RESUMO

Background: South Africa reported a new variant of SARS-CoV-2, named 'Omicron,' to the World Health Or-ganization on November 24, 2021. Scientometric analysis quantify all currently available written communica-tion, the authors of that communication, and their citation analysis. The study's goal was to use the Scopus and Web of Science databases to look at the research metrics of Omicron publications published between Jan-uary 1965 and March 2020. Methods:All scientific research outputs with the word 'Omicron' in the title were retrieved from the Web of Science (January 1965 to March 2022) and Scopus (January 1896 to March 2022) databases on April 10, 2022. The data was analyzed based on year-wise publications; leading authors; predominant journals in publishing, highly cited articles with citations; type of publications; subject classification, frequently used keywords, geo-graphical distribution of publication, language, and more contributed institutions. Results: There were 1229 research outputs for WoS and 655 from Scopus. The number of publications for WoS increased from 22 in 1965 to 265 in 2022, while Scopus increased from 1 in 1896 to 356 in 2022. Both the databases identified the author Yuen KY as the highest contributor; Journal of Virology and Nature as the predominant journals; the Lancet as highly cited journal; majority as original articles; frequently used key-words as 'SARS-CoV-2'; the United States of America as the most productive country; majority publication in English. The publications were mainly on the subjects Chemistry and Medicine by WoS and Scopus, respec-tively. The most productive institute was the ‘University of California Systems’ by WoS and the ‘University of Hong Kong’ by Scopus. Conclusion: The term 'Omicron' first appeared in the domain of Chemistry in the late 18th century. The growth pattern of publication was not consistent. The above research metrics will be helpful to researchers in the coming days.

RESUMO

Background: A study related to an overview of the editorial workflow, editorial decision-making and timelines of the Indian Journal of Dermatology, Venereology and Leprology (IJDVL) had been published earlier. However, a study on publication pattern, citations, contributing organizations, most cited publications etc. of IJDVL has not been performed till now. Objectives: This study aims to identify and analyse the impact of IJDVL on various scientometric indicators viz. year-wise publication growth, impact factor trend, most contributing organizations, global outreach, most cited papers, and cited and citing journals, over the years 2007 to 2019. Methods: Data for this study were retrieved from the Web of Science-core collection database of Journal Citation Reports (Clarivate Analytics, 2021) on 12th May 2021. The search was performed by using the advanced search feature of the database. Using the “InCites”, a search for journal citation reports of IJDVL was performed. Results: The highest number of cumulative citations have been received by publications published in the year 2019 with 2,122 citations which is 91.53% in citable items. In the year 2009 journal, the impact factor was 0.976, which jumped to 2.712 (Journal Citation Reports™ 2018). IJDVL received its highest impact factor (3.030) in the year 2019. All India Institute of Medical Sciences, New Delhi is the most prolific organization contributing to IJDVL with 51 publications. Among foreign countries, China is leading with reference to most contributions by any foreign country with 51 publications in IJDVL. Journal of the American Academy of Dermatology having an impact factor 8.277 has been cited 145 times in this journal. Limitations: Only one database was used for the study. Conclusion: The high proportion of frequently cited articles in recent years, together with its currently high journal impact factor and quartile two-factor, give sustenance to the view that IJDVL publishes high-standard articles relevant to dermatology research and clinical practice

RESUMO

ABSTRACT Introduction Pulmonary neuroendocrine tumors account for approximately 20% of all primary lung tumors. Few studies summarize the current body of pulmonary neuroendocrine tumors studies worldwide. Objective A quantitative scientometric analysis was conducted to evaluate the development of applications and innovations and to analyze their contribution to various areas of improvement in treatment and diagnosis of pulmonary neuroendocrine tumors. Methods We searched for studies published in the last 20 years in the databases United States National Library of Medicine (PubMed), Scientific Electronic Library Online (SciELO), Scopus, and Web of Science, using the terms 'pulmonary neuroendocrine tumors', 'bronchial neuroendocrine tumors', 'bronchial carcinoid tumors', 'pulmonary carcinoid', 'typical pulmonary carcinoid', 'atypical pulmonary carcinoid', 'pulmonary carcinoid and diagnosis', 'pulmonary carcinoid and treatment', 'pulmonary carcinoid and epidemiology' and 'pulmonary carcinoid and prognosis'. Results Our results showed the number of publications increased significantly over the study period and was strongly associated with the economic or financial situation of the publications' countries of origin. We observed a predominance of studies on histological diagnosis compared to treatment, and among the studies related to treatment, a predominance of retrospective studies relative to prospective studies was found. Conclusion Based on the published literature, we concluded research on pulmonary neuroendocrine tumors still seems to be incipient, because it favors studies related to histological characterization of the disease, and therapeutic studies are still predominantly of a retrospective nature.

RESUMO

Abstract: Elasmobranchs exhibit the biggest population declines among vertebrates, being considered one of the groups with the highest risk of extinction. The Brazilian Amazon Coast (BAC) is considered a priority area for elasmobranch conservation, as many species are endemic to the region, and most of them are threatened with extinction. The present study made a scientometric analysis using the IRAMUTEQ method (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires) to evaluate the trends of research with elasmobranchs in BAC in the last four decades. Ten research trends were identified, highlighting "Biodiversity", "Reproduction", "Trophic Ecology" and "Conservation". However, most of the publications found are aimed at understanding the diversity and abundance of species in the region, with the number of studies focused on reproduction, feeding and other aspects of the biology and ecology of elasmobranchs in the BAC being less expressive. Although the research area "Conservation" stood out in the search, the amount of relevant information so that management and conservation measures can be implemented is still low. Lastly, despite following the global trend of studies with elasmobranchs between 2000 and 2010, investigations into the BAC need to advance, especially considering the poor level of basic information on most species (Biology and population dynamics) and the incomplete knowledge of specific composition of elasmobranch species in the entire area, aspects relevant to conservation and more applied studies that rely on more recent methodologies and technologies.


Resumo: Elasmobrânquios apresentam os maiores declínios populacionais entre os vertebrados, sendo considerado um dos grupos com maior risco de extinção. O Litoral Amazônico Brasileiro (BAC) é considerado uma área prioritária para conservação de elasmobrânquios, pois várias espécies são endêmicas da região, e a maioria delas estão ameaçadas de extinção. O presente estudo fez uma análise cientométrica aplicando o método IRAMUTEQ (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires) para avaliar as tendências de pesquisas com elasmobrânquios no BAC nas últimas quatro décadas. Dez tendências de pesquisa foram identificadas, destacando-se "Biodiversidade", "Reprodução", "Ecologia trófica" e "Conservação". Entretanto, a maioria das publicações encontradas é voltada para o conhecimento da diversidade e abundância das espécies na região, sendo o número de estudos voltados para a reprodução, alimentação e outros aspectos da biologia e ecologia de elasmobrânquios do BAC menos expressivo. Apesar da área de investigação "Conservação" ter se destacado na busca, a quantidade de informações relevantes para que medidas de manejo e conservação possam ser implementadas ainda é baixa. Por fim, apesar de seguir a tendência mundial de estudos com elasmobrânquios entre 2000 a 2010, as investigações sobre o BAC precisam avançar, especialmente considerando o baixo nível de informações básicas sobre a maioria das espécies (biologia e dinâmica populacional) e o conhecimento incompleto da composição específica das espécies de elasmobrânquios em toda a área, aspectos relevantes para a conservação e estudos mais aplicados e que contem com metodologias e tecnologias mais recentes.

RESUMO

Abstract: Fire is a key ecological factor affecting biodiversity structure and composition. Fires' effects on biodiversity can be beneficial or harmful depending on how, where, when, and why they occur. The impacts of fire on fauna vary according to species ecology and the fire regime. To understand the research effort relating fire, fauna, and mammals, we surveyed papers published in World and in Brazil. Only 5% of the publications between 1970 and 2019 with fire subject dealt with fauna and 0.5% with mammal. For Brazil, we obtained 7% of papers for fauna and 3% for mammal. The Brazilian Biome with more papers was Cerrado, followed by Atlantic Forest, Amazon, Pampas, Caatinga and Pantanal. The United States of America and Australia stand out as protagonists in their continents with the largest papers number. The volume of research is related to investment in Research and Development and to occurrence of fires. The slope of temporal trend shows the terms related to wildfire have more papers than prescribed burn and there is less interest in fauna and mammal research. It is necessary to form research groups with these themes as research lines and intensify research relating fire ecology and mammals. There is yet no unified understanding of how fire may influence animal diversity and how it influences the vegetative structure and subsequently the resources which wildlife rely on. We consider this information is essential to establish efficient conservation policies.


Resumo: O fogo é um fator ecológico que pode determinar os padrões de diversidade, estrutura e composição da biodiversidade. Assim, o fogo pode ser favorável ou prejudicial, dependendo de como, onde, quando e porquê ocorre. Os impactos do fogo na fauna variam de acordo com a ecologia das espécies e o regime de fogo. Levantamos a quantidade de artigos publicados no mundo e no Brasil para entender o esforço de pesquisa que relaciona fogo, fauna e mamíferos. Apenas 5% das publicações entre 1970 e 2019 com o assunto fogo tratam de fauna e 0,5% de mamíferos. Para o Brasil, obtivemos 7% dos artigos para fauna e 3% para mamíferos. O bioma brasileiro com mais artigos foi o Cerrado, seguido por Mata Atlântica, Amazônia, Pampa, Caatinga e Pantanal. Os países que se destacam como protagonistas em seus continentes, com maior número de publicações, são Estados Unidos da América e Austrália. O volume de pesquisas está relacionado aos investimentos em pesquisa e desenvolvimento e à ocorrência de incêndios florestais. A regressão linear demonstra que os termos relacionados a incêndios florestais têm mais publicações do que os relacionados a queimas prescritas e há menos interesse em pesquisas relacionadas a fauna e a mamíferos. Diante disso, acreditamos ser necessário formar grupos de pesquisa nesses temas e intensificar os estudos relacionando ecologia do fogo e mamíferos. Ainda não existe um entendimento único sobre a influência do fogo na diversidade de animais e na estrutura da vegetação e, subsequentemente, nos recursos dos quais a vida selvagem depende. Consideramos que essas informações são essenciais para estabelecer políticas públicas de conservação mais eficientes.

RESUMO

Abstract Aquatic macrophytes have a recognized role in ecosystem structuring and an important position in trophic cascades interactions, whose understanding is to improve water quality. In recent years, the number of studies on the role of aquatic macrophytes in trophic webs and interactions has increased, but South America has made little progress in research in the area. In this study, we investigated the main gaps and perspectives for future studies on macrophytes and trophic interactions, analyzing global publications, especially those conducted by South American researchers. We accessed publications using an international database (Thomson Reuters ISI-Web of Knowledge-(formerly Institute for Scientific Information)) from 1980 to 2015. We ranked each article by ecosystem and study approach, biological organization and interacting taxonomic groups (phytoplankton, periphyton, zooplankton, aquatic invertebrates, fish and birds), countries publishing in cooperation and affiliations. The results showed that published studies (n = 242) emphasizing aquatic plants in trophic interactions increased in 35 years. Comparing the contributions of the 32 countries investigated, those from South America as first affiliation, had few publications (n = 26) and in cooperation (n = 7). The largest volume of articles indexed by the researchers dealt with the dynamics and structure of aquatic assemblages, webs and trophic interactions. Ecosystems such reservoirs and wetlands have received little attention. Large numbers of studies have encompassed community-wide aquatic approaches, including in South American studies, the interactions between macrophytes, zooplankton and phytoplankton were the second most studied interactions of all indexed articles. Knowledge about trophic cascade and interactions has been successfully enhanced in several countries with the purpose of restructuring communities and restore water quality of many ecosystems. In summary, we conclude that studies in the area of trophic interactions mediated by macrophytes may be directed in a way to attenuate international asymmetries, encouraging the increase of scientific productivity in South America.

Nos últimos anos, o número de estudos sobre o papel das macrófitas aquáticas nas interações e teia trófica aumentaram mas, a América do Sul progrediu pouco em pesquisas na área. Nesse estudo investigamos as principais lacunas e perspectivas para estudos futuros sobre macrófitas e interações tróficas analisando publicações mundiais, especialmente aquelas conduzidas por pesquisadores sul-americanos. Acessamos publicações usando base de dados internacional (Thomson Reuters ISI Web of Knowledge) entre 1980 a 2015. Computamos para cada artigo a organização biológica e grupos taxonômicos em interação (fitoplâncton, perifíton, zooplâncton, invertebrados aquáticos, peixes e aves), ecossistema estudado e abordagem de pesquisa, a cooperação entre países da América do Sul e demais, além das filiações. Os resultados mostraram que estudos publicados (n = 242) enfatizando plantas aquáticas em interações tróficas cresceram em 35 anos. Comparando as contribuições dos 32 países investigados, aqueles da América do Sul apresentaram baixo número de indexações (n= 26), poucos em cooperação (n= 7). O maior volume de publicações indexadas pelos pesquisadores trataram sobre a dinâmica e estrutura das assembléias aquáticas, teias e interações tróficas. Reservatórios e áreas alagadas têm recebido pouca atenção. Grande número de estudos compreeenderam abordagems de toda comunidade aquática e interações entre macrófitas, fitoplâncton, zooplâncton e peixes. Em síntese, concluimos que estudos enfatizando as interações tróficas mediadas pelas macrófitas poderão ser direcionados de maneira a atenuar assimetrias internacionais, encorajando o aumento da produtividade científica na América do Sul. O conhecimento sobre as interações tróficas em cascata tem sido desenvolvido com sucesso em diversos países cujas finalidades tem sido reestruturar comunidades e restaurar a qualidade da água de muitos ecossistemas.

RESUMO

Resumen La creciente producción de las revistas de psicología colombianas en las últimas décadas lleva a preguntas sobre la relevancia e impacto regional e internacional de su productividad. Considerando la falta de esfuerzos recientes para evaluar el resultado de estas revistas en diferentes fuentes de información, el presente estudio analizó la producción, colaboración e impacto de las revistas de psicología colombianas entre 2000 y 2016 utilizando información de las siguientes bases de datos: Scopus, Scielo, Redalyc, y Journal Scholar Metrics. Analizamos 3915 artículos publicados en 13 revistas. Se incluyeron las revistas que estaban indexadas en varias de estas bases de datos al tiempo durante el tiempo de observación, lo que permitió realizar comparaciones. Observamos la diversificación y el crecimiento de las revistas en todos los indicadores propuestos, con diferentes grados de visibilidad y calidad según los criterios utilizados. Aunque todas las revistas en general mostraron resultados regionales e internacionales similares, algunas se destacaron en todos los indicadores, lo que a su vez invita a otras revistas a mejorar sus indicadores. Concluimos que la producción colombiana en psicología es visible a nivel regional. Además, las revistas deben aumentar algunos de los indicadores para poder compararlos con otros puntos de referencia de acceso abierto regionales e internacionales, ya que es el modelo bajo el cual se concibieron originalmente.


Abstract The growing output of Colombian psychology journals over past decades leads to questions regarding the regional and international relevance and impact of their productivity. Considering the lack of recent efforts to assess the output of these journals across different information sources, the present study analyzed the production, collaboration, and impact of Colombian psychology journals between 2000 and 2016 using information from the following databases: Scopus, Scielo, Redalyc, and Journal Scholar Metrics. We analyzed 3915 articles published across 13 journals. A journal was included in the analysis if it was indexed in several of these databases, which allowed for multiple comparisons. We observed journals' diversification and growth across all the proposed indicators, with different degrees of visibility and quality depending on the criteria used. Although all the journals generally showed similar regional and international results, some excelled across indicators, which in turn challenges other journals to improve their scores. We conclude that Colombian production in psychology is visible on a regional level. Moreover, journals need to increase some of the indicators so they can be compared with other regional and international open-access benchmarks, which is the model in which they were originally conceived.

RESUMO

Abstract Recently, ecological niche models have been employed to investigate the potential geographical distribution of species. However, it is necessary to analyze the vast number of publications on this topic to understand the trends and biases of research using ecological niche models (ENMs). Therefore, this study aims to investigate trends in the scientific literature regarding studies on ENMs. For the quantitative analysis of the literature on ENMs, we performed a search in the Thomson ISI (Web of Science) database between 1991 and 2013. The search identified 3042 papers containing preselected keywords in either the title or abstract. The results showed that the number of papers has increased over the years (r=0.77, P 0.001), with a sharp increase in recent years, highlighting the widespread use of the ENMs. There was an increase in the diversity of journals that published papers about ENMs (r=0.97, P 0.001). The research was conducted in different countries, predominantly the United States of America (550 papers), and the most commonly used method was the Maximum Entropy method (312 papers). Regarding the taxonomic group, most research has been conducted on plants (402 papers, or 28.36% of the total). There was no relationship between the modeling method used and the taxonomic group studied (2=4.8, P=0.15). Finally, the wide availability of biological, environmental and computational resources has elicited the broad use of tools for ENMs. Despite the conceptual discussions of the ENMs, this method is currently the most effective way to evaluate the potential geographical distribution of species, and to predict the distribution under different environmental conditions (i.e., future or past scenarios).


Resumo Recentemente, modelos de nicho têm sido empregados para investigar a distribuição geográfica potencial de espécies. Porém, é necessário analisar a vasta quantidade de publicações sobre o referido tema, a fim de compreender as tendências e vieses das pesquisas que usam modelos de nicho ecológico (MNEs). Portanto, esse trabalho tem por objetivo investigar as tendências da literatura científica de trabalhos sobre MNEs. Para a análise quantitativa das publicações sobre MNEs, foi realizada uma busca na base de dados Thomson ISI (Web of Science), entre o período de 1991 a 2013. A pesquisa agrupou 3042 documentos que continham nas palavras-chave, no título ou no resumo os termos selecionados para a busca. Os resultados mostraram que de forma geral o número de artigos tem aumentado ao longo dos anos (r=0,77, P 0,001), com um acentuado crescimento nos anos mais recentes, destacando o amplo uso de MNEs. Ao longo dos anos percebeu-se um aumento da diversidade de revistas que publicam sobre o assunto (r=0,97, P 0,001). As pesquisas têm sido desenvolvidas em diferentes países, com predomínio dos Estados Unidos (550 artigos) e o método mais utilizado foi o de Máxima Entropia (312 artigos). Quanto ao grupo taxonômico, a maioria dos estudos tem ocorrido com plantas (402 artigos ou 28,36% do total de artigos). Não houve relação entre método de modelagem e grupo taxonômico (2=4,8, P=0,15). Por fim, a ampla disponibilidade de dados biológicos, ambientais e recursos computacionais tem propiciado um amplo uso de MNEs. Apesar das discussões conceituais sobre MNEs, o método atualmente é o mais eficaz para conhecer a distribuição geográfica potencial das espécies e ainda projetar essa distribuição sob diferentes condições ambientais (i.e. cenários futuros, passado).

Abstract Recently, ecological niche models have been employed to investigate the potential geographical distribution of species. However, it is necessary to analyze the vast number of publications on this topic to understand the trends and biases of research using ecological niche models (ENMs). Therefore, this study aims to investigate trends in the scientific literature regarding studies on ENMs. For the quantitative analysis of the literature on ENMs, we performed a search in the Thomson ISI (Web of Science) database between 1991 and 2013. The search identified 3042 papers containing preselected keywords in either the title or abstract. The results showed that the number of papers has increased over the years (r=0.77, P<0.001), with a sharp increase in recent years, highlighting the widespread use of the ENMs. There was an increase in the diversity of journals that published papers about ENMs (r=0.97, P<0.001). The research was conducted in different countries, predominantly the United States of America (550 papers), and the most commonly used method was the Maximum Entropy method (312 papers). Regarding the taxonomic group, most research has been conducted on plants (402 papers, or 28.36% of the total). There was no relationship between the modeling method used and the taxonomic group studied (χ2=4.8, P=0.15). Finally, the wide availability of biological, environmental and computational resources has elicited the broad use of tools for ENMs. Despite the conceptual discussions of the ENMs, this method is currently the most effective way to evaluate the potential geographical distribution of species, and to predict the distribution under different environmental conditions (i.e., future or past scenarios).


Resumo Recentemente, modelos de nicho têm sido empregados para investigar a distribuição geográfica potencial de espécies. Porém, é necessário analisar a vasta quantidade de publicações sobre o referido tema, a fim de compreender as tendências e vieses das pesquisas que usam modelos de nicho ecológico (MNEs). Portanto, esse trabalho tem por objetivo investigar as tendências da literatura científica de trabalhos sobre MNEs. Para a análise quantitativa das publicações sobre MNEs, foi realizada uma busca na base de dados Thomson ISI (Web of Science), entre o período de 1991 a 2013. A pesquisa agrupou 3042 documentos que continham nas palavras-chave, no título ou no resumo os termos selecionados para a busca. Os resultados mostraram que de forma geral o número de artigos tem aumentado ao longo dos anos (r=0,77, P<0,001), com um acentuado crescimento nos anos mais recentes, destacando o amplo uso de MNEs. Ao longo dos anos percebeu-se um aumento da diversidade de revistas que publicam sobre o assunto (r=0,97, P<0,001). As pesquisas têm sido desenvolvidas em diferentes países, com predomínio dos Estados Unidos (550 artigos) e o método mais utilizado foi o de Máxima Entropia (312 artigos). Quanto ao grupo taxonômico, a maioria dos estudos tem ocorrido com plantas (402 artigos ou 28,36% do total de artigos). Não houve relação entre método de modelagem e grupo taxonômico (χ2=4,8, P=0,15). Por fim, a ampla disponibilidade de dados biológicos, ambientais e recursos computacionais tem propiciado um amplo uso de MNEs. Apesar das discussões conceituais sobre MNEs, o método atualmente é o mais eficaz para conhecer a distribuição geográfica potencial das espécies e ainda projetar essa distribuição sob diferentes condições ambientais (i.e. cenários futuros, passado).

RESUMO

Con el objetivo de determinar el comportamiento de los índices de citación de la investigación en salud de Cuba, procesada en Scopus en el periodo 2009-2013, con respecto a un grupo de países latinoamericanos seleccionados, se examinaron los datos suministrados por Scival, su plataforma para estudios cienciométricos, según áreas del conocimiento, a partir de tres indicadores: promedio de citas recibidas por las contribuciones, porcentaje de artículos citados y número de países citantes. Los índices de citación de las contribuciones en salud de Cuba, en relación con los países estudiados, salvo en el caso de las categorías de neurociencias y medicina, fueron los más bajos. Existe falta de correspondencia entre el desarrollo alcanzado por el sector de la salud en el país, reconocido a escala internacional, su volumen de producción científica, según Scopus, y sus índices de citación en comparación con los países de la región, escogidos para el estudio.


In order to determine the behavior of citation indexes of health research in Cuba, processed in Scopus in the period from 2009-2013, regarding a selected group of Latin American countries, the data supplied by Scival were examined, its platform for scientometric studies, according to areas of knowledge, based on three indicators: average citations received by the contributions, per cent of articles cited and number of citing countries. Citation indexes of health contributions of Cuba, in relation to the countries studied, except Neuroscience and Medicine categories were the lowest ones. There is mismatch between the development achieved by the health sector in the country, internationally recognized, the volume of scientific production, according to Scopus, and their citation rates compared with countries in the region, chosen for the study.

RESUMO

Introducción: se admite que hay un abismo tecnológico entre los diversos continentes. Si bien contamos con multitud de informes sobre la producción científica y su evolución a nivel mundial, faltan estudios de esta misma índole en el campo de las patentes. Los estudios cienciométricos sobre patentes son escasos y limitados, especialmente sobre áreas específicas del conocimiento. Objetivo: analizar la situación tecnológica de la Inmunología en Latinoamérica, entre 2004 y 2011. Métodos: los documentos de patentes en el área de la Inmunología se obtuvieron a través de SCOPUS, con el análisis de las patentes solicitadas vía Tratado de Cooperación en Materia de Patentes, valorando los solicitantes, sus países de origen, los sectores económicos que patentan, así como la cooperación entre países. Resultados: en el período de estudio, 89 países solicitaron 17 281 patentes en Inmunología. Los países de la OCDE solicitaron el 97,28 % de estas, la Unión Europea el 30,76 % y Latinoamérica el 149 (0,86 %). Los países que más patentes solicitaron fueron Brasil con 43 y Cuba con 31. Los principales cosolicitantes fueron: Argentina y Brasil con EE.UU. (10 cada uno), y México con EE.UU. (8); entre los países latinoamericanos se encontraron Bahamas-Belice, Brasil-Uruguay, Chile-Ecuador, Cuba-México y Honduras-México. Las patentes inmunológicas se centraron, especialmente, en productos farmacéuticos y la Biotecnología. Las entidades privadas latinoamericanas solicitaron el 46 % de las patentes, las OPIs el 28 %, las universidades el 25 % y los hospitales el 3 %. Conclusiones: las diferencias tecnológicas, al menos en esta área de conocimiento, se han ido reduciendo. Bermudas e Islas Caimán ocupan la octava y novena posición mundial, respectivamente, por patentes/habitante; Brasil es el vigésimo país en patentes/INB-PP; Uruguay es el onceno en patentes/inversión en I+D+i en % INB, y México es el vigésimo en patentes/I+D+i en % del INB. Somos conscientes de que, al analizar únicamente un área de conocimiento, se produce un sesgo importante, pero nos permite ver y valorar la evolución de cada país hacia esta disciplina.


Introduction: a great technological divide is recognized to exist between the continents. Even though there is a multitude of reports about scientific production and its evolution around the world, relevant studies are still lacking in the field of patents. Scientometric studies dealing with patents are few and limited, particularly in certain knowledge areas. Objective: analyze the technological status of immunology in Latin America between 2004 and 2011. Methods: Immunological patent documentation was obtained from Scopus, and an analysis was conducted of the patents applied for through the Patent Cooperation Treaty. An evaluation was carried out of applicants, their country of origin, the patenting economic sectors and the cooperation between countries. Results: during the study period 89 countries applied for 17 281 immunological patents. Countries from the Organization for Economic Co-operation and Development applied for 97,28 % of the patents, the European Union for 30,76 % and Latin America for 0,86 %. The Latin American countries applying for most patents were Brazil (43) and Cuba (31). The main applicants were Argentina and Brazil (10 each) and Mexico (8). Latin American co-applicants included Bahamas-Belize, Brazil-Uruguay, Chile-Ecuador, Cuba-Mexico and Honduras-Mexico. Most immunological patents were for pharmaceutical products and biotechnology. Latin American private institutions applied for 46% of the patents, public research offices for 28 %, universities for 25 % and hospitals for 3 %. Conclusions: technological differences, at least in this knowledge area, have gradually lessened. Thus Bermuda and the Cayman Islands rank 8th and 9th worldwide, respectively, in patents per inhabitant. Brazil ranks 20th in patents/Gross National Income-Purchasing Power Parity. Uruguay ranks 11th in patents/investment in RDI in % of the Gross National Income, and Mexico ranks 20th. Significant bias may result from analyzing just one knowledge area, but it makes it possible to determine and assess the evolution of the study subject in each country.

RESUMO

O combustível fóssil dá sinais de esgotamento das suas reservas além de afetar o meio ambiente devido à poluição decorrente de sua queima. Surgiu assim um novo desafio: encontrar um combustível substituto que seja renovável e que seja menos poluente. O biodiesel surgiu como potencial substituto do combustível fóssil, por ser oriundo de várias matérias primas, reduzir o impacto ambiental gerado por poluição e ainda trazer vários benefícios sociais. Porém essa tecnologia é nova e ainda precisa ser aperfeiçoada. Vários trabalhos científicos vêm surgindo com o intuito de trazer melhoria para o biodiesel. Por meio da Cienciometria é possível saber a tendência de pesquisa desses trabalhos, sendo este fato importante para a sociedade acadêmica, para que possam ser realizados novos estudos de biodiesel. Sendo assim, objetivou-se neste trabalho fazer uma análise cienciométrica do biodiesel. O banco de dados utilizado foi o "SciVerseScopus". Foi realizada uma busca de todos os trabalhos que possuía no título a palavra biodiesel*. Os trabalhos foram analisados a partir de 1993, primeiro ano de registro para o termo, até 2010. As seguintes informações foram levantadas: a)Ano de publicação, b)Tipo de trabalho, c)Tipo do periódico em que o trabalho foi publicado, d)Nome do periódico em que o trabalho foi publicado, e)Área de concentração, f)Palavras-chave, g)Idioma, h)País de publicação, e i)Matéria prima utilizada para a obtenção do biodiesel estudado em trabalhos brasileiros. De uma forma geral os trabalhos analisados acompanham as tendências mundiais de produção e consumo do biodiesel, mostrando-se importantes para o aperfeiçoamento desta tecnologia.


Fossil fuel is showing signs of depletion of its reserves and affect the environment due to pollution from burning. Thus emerged a new challenge: to find a substitute fuel that is renewable and less polluting. Biodiesel has emerged as a potential substitute for fossil fuel, for it comes from various raw materials, reduce the environmental impact of pollution and also bring many benefits. However this technology is new and still needs to be improved. Several scientific studies have emerged in order to bring about improvement for biodiesel. Through scientometrics is possible to know the trend of research work, which is indeed important for the academic society, that may be new studies of biodiesel. Thus, this study aimed to make a scientometric analysis of biodiesel. The database used was the "SciVerseScopus." We performed a search of all studies that had biodiesel* in the title. The studies were analyzed from 1993, the first year of registration for the term until 2010. The following information was obtained: a) Year of publication, b) type of study, c) Type of the journal where the paper was published, d) name of journal in which the study was published, e) Area of concentration, f) keywords, g) Language, h) Country of publication, i) Raw materials used to obtain biodiesel studied in Brazilian studies. In general the studies analyzed follow world trends in production and consumption of biodiesel, being important for the improvement of technology. New jobs scientometrics of biodiesel can be made taking into account their specific characteristics.

RESUMO

Testate amoebae have a great potential for use in scientific researches due to their ecological characteristics such as abundance, wealth, and generation time. In this way, this study aimed to present a scientometric analysis to describe the evolution of the different advances in researches on testate amoebae and identify a temporal pattern in this evolution. The literature review was based on papers indexed by Thomson Reuters (www.isiwebofknowledge.com) and SciVerse Scopus (www.scopus.com). In total 562 papers were examined. Results showed a pattern of evolution in scientific studies, most with ecological approach with descriptive and predictive designs. At the global level, researches on testate amoebae progressed in both the number of articles published as well as in the areas studied, especially in Europe and North America. The low number of experimental studies and review articles can characterize the lack of more knowledge to be acquired, both from particular observations (descriptive studies) as well as the observations noted sufficiently predictive of work. In Brazil, studies with testate amoebae are still developing, concentrated in only some regions, but the increased number of studies in recent years allows the prediction of the same overall patterns of advance for Brazilian researches. Thus, we conclude that these organisms are being increasingly used as a tool response in ecological studies.


Amebas testáceas possuem grande potencial de utilização em pesquisas de caráter científico pelas suas características ecológicas como abundância, riqueza, e tempo de geração. Nesse sentido, o objetivo do presente estudo foi apresentar uma análise cienciométrica, a fim de descrever a evolução das diferentes abordagens nas pesquisas de tecamebas e identificar um padrão temporal nessa evolução. A revisão dos artigos científicos foi realizada com base nos artigos indexados pela base Thomson Reuters (www.isiwebofknowledge.com) e pela base SciVerse Scopus (www.scopus.com). Foram analisados 562 artigos científicos. Os resultados demonstraram um padrão de evolução nos trabalhos científicos, sendo a maioria de cunho ecológico com delineamentos descritivos e preditivos. Em âmbito global, as pesquisas com tecamebas apresentaram evolução tanto no número de artigos publicados bem como nas áreas estudadas, principalmente na Europa e América do Norte. O baixo número de trabalhos experimentais e de revisão pode caracterizar a falta de maiores conhecimentos a serem ainda adquiridos, tanto a partir das observações particulares (trabalhos descritivos) bem como das observações suficientemente constatadas dos trabalhos preditivos. No Brasil, as pesquisas com amebas testáceas ainda estão em processo de desenvolvimento, concentradas em apenas algumas regiões. Entretanto, o aumento no número de publicações nos últimos anos possibilita a previsão dos mesmos padrões de evolução globais para as pesquisas brasileiras. Assim, é possível concluir que esses organismos estão sendo cada vez mais utilizados como ferramenta resposta nos estudos ecológicos.
