The landscape of hematology research in Brazil: an analysis of data from citation databases

ABSTRACT Introduction: Scientometrics is the field concerned with measuring and analyzing academic literature, using specific metrics and data from bibliometric databases. Hematology is a broad area of science and medicine, from which several landmark scientific discoveries have emerged. Objective: The aim of this report is to provide a snapshot of the landscape of hematology research in Brazil, based on a comprehensive analysis of published studies in hematology whose authors were affiliated to Brazilian institutions from 1980 to 2020. Method: Articles, reviews and letters to the editor with at least one author affiliated to a Brazilian institution were retrieved from Incytes/Web of Science or Scopus databases. Importantly, only papers classified in the subject area "Hematology" by the embedded algorithms of each database were included. Results: Considering all published papers, Brazil is in the 22nd position, contributing with around 1.1% of papers in this period. A clear and sustained increase in publication output can be observed from the early 1990's to the present moment. Publicly-funded higher education institutions were the main contributors to the development and consolidation of the hematology scientific community, which has grown in diversity, with an increasing number of contributions from private institutions. In regard to funding, public agencies have been and remain by large as the most important funder of research in hematology in Brazil. Conclusion: We suggest that continuous monitoring of the temporal trends of some of the data compiled in our report could potentially contribute to a clearer picture of the development of hematology research in Brazil.

Australia’s Pharmacology Research: A Scientometric Assessment of High-Cited Papers During 2002–2021

Scientometric review of research on Neglected Tropical Diseases: a 31-year perspective from the Journal of the Brazilian Society of Tropical Medicine

ABSTRACT Background: To analyze the temporal evolution of research on Neglected Tropical Diseases (NTDs) published by the Journal of the Brazilian Society of Tropical Medicine (JBSTM). Methods: We performed an analysis of the scientific production in JBSTM on NTDs using an advanced search, which included authors' descriptors, title, and abstract, and by combining specific terms for each NTDs from 1991 to 2021. Data related to authors, countries of origin, institutions, and descriptors, were evaluated and analyzed over time. Bibliographic networks were constructed using VOSviewer 1.6.16. Results: The JBSTM published 4,268 scientific papers during this period. Of these 1,849 (43.3%) were related to NTDs. The number of publications on NTDs increased by approximately 2.4-fold, from 352 (total 724) during 1991-2000 to 841 (total 2,128) during 2011-2021, despite the proportional reduction (48.6% versus 39.5%). The most common singular NTDs subject of publications included Chagas disease (31.4%; 581/1,849), leishmaniasis (25.5%, 411/1,849), dengue (9.4%, 174/1,849), schistosomiasis (9.0%; 166/1,849), and leprosy (6.5%, 120/1,849), with authorship mostly from Brazil's South and Southeast regions. Conclusions: Despite the proportional reduction in publications, JBSTM remains an important vehicle for disseminating research on NTDs during this period. There is a need to strengthen the research and subsequent publications on specific NTDs. Institutions working and publishing on NTDs in the country were concentrated in the South and Southeast regions, requiring additional investments in institutions in other regions of the country.

Half a century of Sri Lanka research: Subjects, researchers, institutions, journals and impact (1973-2019) / Medio siglo de investigación en Sri Lanka: temas, investigadores, instituciones, revistas e impacto (1973-2019)

Abstract Introduction: Bibliometric analyses of research in Sri Lanka, a lower-middle income island nation in South Asia, has focused mainly on medical research, concluding that there is a need for increased research productivity and impact, and for local solutions to health concerns. There has been no general bibliometric analysis across scientific disciplines in the nation, or any study that covers a long period of time to identify general time trends. Objective: To measure and analyse Sri Lanka research by focusing on subjects, authors, institutions, journals and citation for half a century. Methods: We used an advanced search method to extract publications with the word "Sri Lanka" in the SCI-EXPANDED, and calculated indicators such as total citations from Web of Science Core Collection since publication year to the end of 2019, citations in 2019, and mean citations per publication. Journal data were taken from 2019 Journal Citation Report. Affiliation re-classification was done to ensure consistency regarding the origin of all publications. Publications were further analysed based on collaboration, and first and corresponding authorship. Results: We retrieved 16 069 publications in 19 document types (77 % articles). Corrections had the highest number of authors per publication (616) followed by articles (116). Four articles had more than 5 000 authors and 593 articles had more than 1 000 authors. The highest citations in this database were for international megaprojects where Sri Lanka authors played minor roles. The UK had the most collaborative articles with Sri Lanka (19 %). The articles were published in 3 051 journals across 177 Web of Science categories. The category of Public, environmental and occupational health, with 193 journals, had 6.7 % of all articles, followed by environmental sciences (6.6 %). Conclusion: Sri Lanka has an unusually strong pattern of participating as small role players in international megaprojects about health and physics. Sri Lanka authors should be encouraged to expand their horizons by researching non-applied fields that are the basis of all innovation; to strengthen their own journals so that they have better visibility and impact, and to improve their positions in international projects that are published in larger journals.

Resumen Introducción: Los análisis bibliométricos de la investigación en Sri Lanka, una nación insular de ingresos mediano-bajos en el sur de Asia, se han centrado principalmente en la investigación médica, concluyendo que existe la necesidad de aumentar la productividad y el impacto de la investigación, y de soluciones locales a los problemas de salud. No ha habido un análisis bibliométrico general de disciplinas científicas o algún estudio que cubra un período largo de tiempo para identificar tendencias generales. Objetivo: Medir y analizar la investigación de Sri Lanka centrándose en temas, autores, instituciones, revistas y citas, durante medio siglo. Métodos: Utilizamos un método de búsqueda avanzada para extraer publicaciones con las palabras "Sri Lanka" en el SCI-EXPANDED, y calculamos indicadores como el total de citas de Web of Science Core Collection desde el año de publicación hasta finales de 2019, citas solo en 2019, y media de citas por publicación. Los datos de revistas son del Journal Citation Report 2019. Revisamos manualmente las afiliaciones para garantizar su coherencia, y, de todos los tipos de publicación, analizamos en detalle los artículos en función de la colaboración y la autoría. Resultados: Hallamos 16 069 publicaciones en 19 tipos de documentos (77 % artículos). Las correcciones tuvieron el mayor número de autores por publicación (616), seguidas de los artículos (116 autores en promedio); cuatro artículos tenían más de 5 000 autores y 593 artículos tenían más de 1 000 autores. Las citas más altas en esta base de datos fueron para megaproyectos internacionales en los que los autores de Sri Lanka desempeñaron papeles menores. El Reino Unido tuvo más artículos colaborativos con Sri Lanka (19 %). Los artículos se publicaron en 3 051 revistas de 177 categorías del Web of Science. La categoría d Salud pública, ambiental y ocupacional, con 193 revistas, tuvo el 6.7 % del total de artículos, seguida de Ciencias ambientales (6.6 %). Conclusión: En Sri Lanka hay una tendencia inusual a participar como pequeños actores en megaproyectos internacionales sobre salud y física. Debería alentarse a quienes hacen ciencia en Sri Lanka a ampliar sus horizontes investigando campos no aplicados, que son la base de la innovación; a fortalecer sus propias revistas para lograr mayor visibilidad e impacto, y a mejorar su ubicación en proyectos internacionales que se publican en revistas más grandes.

Blood diffusion to novel therapies: A quantitative analysis of scholarly output in Haemophilia from India

Lack of specific protein factors, such as factor VIII and factor IX, results in haemophilia, a genetic bleeding condition. Due to its genetics, haemophilia affects an individual, but we can see how it has an impact on a whole generation. The goal of this study is to determine the extent to which our Indian researchers have been able to advance this highly sought-after field. Although this study was intended to last 75 years, it had to be restricted to the years 1991 to 2021 due to a shortage of publications at the time of data mining. There was a total of 81 publications found, and after analysing them, it was found that India and the USA collaborated more frequently than France and the UK. The National Institute of Immunohaematology (NIIH), located in Mumbai, is India's most productive institution in terms of the number of publications or ongoing work. Haemophilia, factor viii, and gene therapy were the most commonly used keywords. Indian researchers still need to put in a lot of effort in this area because, according to studies from around the world, haemophilia is spreading like a fire. Continuous research and knowledge of the needs of the population are required if we are to improve not only our position in the world but also the way we are treated, which would make life better.

Comparative study of scientific articles on MMR vaccines published from India over the last few decades

The MMR vaccine as we know is a vital vaccine to protect against three disease-causing microbes- measles, mumps, and rubella. To commemorate 75 years of Indian independence, the present study delves into the achievement of Indian research and lists out articles retrieved from the Web of Science Core Collection database on the domain of MMR vaccine research. The data has been restricted to the publication from India, thereby, has throwing some understanding into the MRR vaccine research in India over the last 28 years- 1994 to 2021. The data have been compared based on scientometric analysis. Qualitative and quantitative analysis have also been taken into account in order to give a comparative insight into the research. The comparison was done based on citation data, usage count data, year of publication, journals, publication media, domains focussed on the papers, and type of document. Astonishingly, in 2021, the most number of papers were published, most of them have related MMR vaccine as a potential immunity developer against COVID-19 infection. A total of 43 articles were retrieved from the search, the numbers are quite big, and the highest citation among them being 99 which was published in 2014, which is quite impressive for such a short duration of time. The comparative study suggests a positive growth of MMR vaccine research in India.

Global research trends of interleukin-6 in SARS-CoV-2 infection

IL-6 levels are significantly elevated in COVID-19 patients and are associated with poor clinical outcomes. Inhibiting IL-6 is thought to be a unique therapeutic strategy for the control of dysregulated host responses in SARS-CoV-2. The present study focuses on evaluating the research productivity of IL-6 level in SARS-CoV-2 infection using various bibliometric indicators and analysed 4510 research papers related to IL-6 levels in SARS-CoV-2 from the Scopus database and VOSViewer© tool applied for visualization. The results revealed that ascendant trends in the publications and USA, China and Italy have secured top three position in numbers of publications. Study observed that “Dagna L.” received top prolific author rank. Article entitled “Clinical features of patients infected with 2019 novel coronavirus in Wuhan, China” received maximum of 15364 total citations, whereas “Frontiers in Immunology” and “Journal of Medical Virology” secured in top two highly productive journals in the subject with extreme link strength. With regard to organisation, “Tongji Medical College-China” reported highly dynamic organization. “Covid-19”; “SARS-Cov-2”; “Interleukin” received maximum occurrences with high link strength. In view of global mounting public health issue of COVID-19, primarily due to increased viral transmissibility and associated cytokine storm, the present study will helpful for the medical professionals to know the research trends and also library authority for updating collection development policy in the specific subject domains.

A comparison of scientometric data and publication policies of ophthalmology journals

Purpose: This retrospective database analysis study aims to present the scientometric data of journals publishing in the field of ophthalmology and to compare the scientometric data of ophthalmology journals according to the open access (OA) publishing policies. Methods: The scientometric data of 48 journals were obtained from Clarivate Analytics InCites and Scimago Journal & Country Rank websites. Journal impact factor (JIF), Eigenfactor score (ES), scientific journal ranking (SJR), and Hirsch index (HI) were included. The OA publishing policies were separated into full OA with publishing fees, full OA without fees, and hybrid OA. The fees were stated as US dollars (USD). Results: Four scientometric indexes had strong positive correlations; the highest correlation coefficients were observed between the SJR and JIF (R = 0.906) and the SJR and HI (R = 0.798). However, journals in the first quartile according to JIF were in the second and third quartiles according to the SJR and HI and in the fourth quartile in the ES. The OA articles published in hybrid journals received a median of 1.17?fold (0.15–2.71) more citations. Only HI was higher in hybrid OA; other scientometric indexes were similar with full OA journals. Full OA journals charged a median of 1525 USD lower than hybrid journals. Conclusion: Full OA model in ophthalmology journals does not have a positive effect on the scientometric indexes. In hybrid OA journals, choosing to publish OA may increase citations, but it would be more accurate to evaluate this on a journal basis

Influência das métricas de mídias sociais nas citações dos periódicos brasileiros de Enfermagem indexados na Scopus / The influence of social media metrics on citations of brazilian nursing journals

O uso de mídias sociais por pesquisadores, instituições, publicações e público em geral, assim como a adoção da altmetria para aferição de impacto de produtos científicos em diferentes plataformas online, vem ao encontro do que preconizam as novas propostas para a comunicação científica. A Enfermagem possui uma produção científica por vezes mais acessível à sociedade o que lhe permite alcançar um público mais amplo e diversificado, por vezes não acadêmico, que acessa, lê e discute temas que muitas vezes fazem parte do seu cotidiano. A tese justifica-se pela carência de estudos brasileiros sobre o uso de modelos, métodos e técnicas estatísticas para medir os efeitos da relação e da possibilidade de usar métricas de mídias sociais para prever o volume de citações de artigos científicos da Enfermagem. Estudo exploratório e de abordagem quantitativa que analisa o efeito das interações em mídias sociais nas citações de 4.776 artigos publicados em onze periódicos brasileiros do campo da Enfermagem indexados na Scopus no período de 2015 a 2019. Os dados de impacto sobre os artigos no Mendeley, Twitter e Facebook, foram fornecidos pela PlumX. Também foram coletados dados altmétricos do corpus nas contas das revistas no Facebook e no Twitter. Para predição de resultados foi utilizado o modelo de regressão Binomial Negativo devido à natureza dos dados disponíveis. Foi observado que 99% do corpus estava coberto no Mendeley, 19,6% no Facebook e 12,6% no Twitter. Foi verificada uma correlação moderada (rs = 0,591, p < 0,05) entre o volume de leitores no Mendeley e o volume de citações na Scopus Os resultados demonstraram uma correlação nula entre as interações recebidas pelos artigos no Facebook (rs = - 0,129, p < 0,05) e no Twitter (rs = 0,141, p < 0,05) com as citações recebidas pelos artigos na Scopus. O modelo de regressão demonstrou que para cada aumento no número leitores em um artigo no Mendeley, mantendo-se outros parâmetros fixos, tem-se um aumento aproximado de 0,7% no número de citações deste artigo na Scopus. Já para cada aumento na variável ano, mantendo os outros parâmetros fixos, tem-se aproximadamente 39,8% de aumento no número de citações recebidas por um artigo na Scopus. Foram postados no Facebook pelos periódicos da Enfermagem 31,3% dos artigos publicados em 2019. O modelo de regressão demonstrou que para cada aumento no número de interações em um artigo no Facebook, mantendose os outros parâmetros fixos, tem-se um aumento médio de 2,2% no número de citações na Scopus. Foram divulgados no Twitter 16,9% dos artigos publicados pelos periódicos em 2019. Ficou evidenciada a natureza díspar do tipo de impacto que é mensurado pelas métricas tradicionais, baseadas em citações, e as métricas alternativas, percebidas em mídias sociais. Reafirma-se o que já foi exposto na literatura: a altmetria pode ser utilizada para complementar, mas não para substituir, o impacto medido pelas métricas tradicionais baseadas em citações formais, permitindo observar de forma mais ampliada como se dão os processos da comunicação científica em ambientes online informais.

The use of social media by researchers, institutions, publications and the general public, as well as the adoption of altmetrics to measure the impact of scientific products on different online platforms, is in line with the new proposals for scientific communication. Nursing has a scientific production that is sometimes more accessible to society, which makes it possible to reach a broader and more varied audience, sometimes non-academic, that accesses, reads and discusses topics that are often part of their daily lives. The dissertation is justified by the lack of Brazilian studies about the use of models, methods and statistical techniques to measure the effects of the relationship and the possibility of using social media metrics to predict the amount of citations of scientific articles in Nursing. This is an exploratory study with a quantitative approach, which analyzes the effect of interactions in social media on the citations of 4,776 articles published in eleven Nursing Brazilian journals indexed in Scopus from 2015 to 2019. PlumX provided the impact of data sharing on articles on Mendeley, Twitter and Facebook. Besides, we collected altmetric data of the corpus on Facebook and Twitter accounts of the journals. To predict the results, we used the Negative Binomial regression model due to the nature of the available data. We found that Mendeley covers 99% of the corpus; Facebook, 19.6% and Twitter, 12.6%. We found a moderate correlation (rs = 0.591, p < 0.05) between the amount of Mendeley readers and the amount of Scopus citations. The results showed a null correlation between the interactions received by the articles on Facebook (rs = - 0.129, p < 0.05) and on Twitter (rs = 0.141, p < 0.05) with the citations received by the articles in Scopus. The regression model showed that for each increase in the number of readers of an article on Mendeley, other parameters remaining fixed, there is an approximate increase of 0.7% in the number of citations of this article in Scopus. For each increase in the variable 'year', other parameters remaining fixed, there is an increase of approximately 39.8% in the number of citations received by an article in Scopus. Nursing journals posted on Facebook 31.3% of the articles published in 2019. The regression model showed that for each increase in the number of interactions in an article on Facebook, other parameters remaining fixed, there is an average increase of 2.2% in the number of citations in Scopus. Twitter posted 16.9% of the articles published by journals in 2019. It is evident the unequal nature of the type of impact that is measured by traditional metrics, based on citations, and alternative metrics, noticed on social media. We reaffirm what literature has already exposed: altmetrics can be used to complement, but not to replace, the impact measured by traditional metrics based on formal citations, allowing a broader perspective of how scientific communication processes take place in informal online environments.

The geographic bias of mammal studies: a comparison of a half a century of research on Palearctic and Neotropical mammals / El sesgo geográfico en el estudio de los mamíferos: comparación de medio siglo de investigación sobre mamíferos paleárticos y neotropicales

Abstract Introduction: There are no studies that specifically compare research output of Palearctic and Neotropical mammalogy; such comparison would be useful for informed decisions in conservation and management. Objective: To compare the scientific documents and citations about Palearctic and Neotropical mammals over half a century. Methods: We compared 50 years (1970-2019) of documents on 60 medium and large-sized (heavier than 1 kg) mammal species, in Scopus and the Web of Science (WoS) Core Collection, considering number of documents and four citation indicators at the species level (h-index, citation rate, total citations, and citations per year). Results: We retrieved 13 274 documents in Scopus and 12 913 in WoS. We found that Palearctic mammals have 3.77 times more documents than Neotropical species in Scopus (3.91 times in WoS), and that the documents recorded 5.95 more total citations in Scopus (6.93 times more in WoS). Palearctic documents also record more yearly citations and a higher h-index in both Scopus and WoS. Scopus retrieved more articles for Neotropical species (2 782 vs. 2 631 in WoS) and had more citations (28 120 vs. 24 977 in WoS); differences for the citation indicators between regions were marker in WoS. The h-index and total citations are greatly affected by how many studies are published, i.e. the region with more production is the one with higher values. The Neotropical articles showed a greater growth rate in the last decade, decreasing the gap between both regions. Conclusion: There is a regional bias in WoS and Scopus, which retrieve more articles and citations about Palearctic mammals than about Neotropical mammals; this bias is worse in WoS and means that an urgent increase in indexed research about Neotropical species is needed to be on par with Palearctic research.

Resumen Introducción: No existen estudios que comparen, específicamente, la investigación de la mastozoología paleártica con la neotropical; pero tales comparaciones serían útiles para tomar decisiones informadas en conservación y manejo. Objetivo: Comparar los documentos científicos sobre mamíferos paleárticos y neotropicales, y su impacto en citas, durante medio siglo. Métodos: Comparamos 50 años (1970-2019) de documentos sobre 60 especies de mamíferos de tamaño mediano y grande (más de 1 kg), en Scopus y la colección principal del Web of Science (WoS), considerando el número de documentos y cuatro indicadores de citas a nivel de especie (índice h, tasa de citas, total de citas y citas por año). Resultados: Recuperamos 13 274 documentos en Scopus y 12 913 en WoS, y encontramos que los mamíferos paleárticos tienen 3.77 veces más documentos que las especies neotropicales en Scopus (3.91 veces en WoS), y que los documentos registran 5.95 más citas totales en Scopus (6.93 veces más en WoS). Los documentos paleárticos también registran más citas anuales y un índice h más alto, tanto en Scopus como en WoS. Scopus recuperó más artículos para especies neotropicales (2 782 vs. 2 631 en WoS) y tuvo más citas (28 120 vs. 24 977 en WoS). Las diferencias para los indicadores de citas entre regiones fueron más marcadas en WoS. El índice h y el total de citas se ven muy afectados por la cantidad de estudios publicados, es decir, la región con más producción será la que tenga indicadores más altos. Los artículos neotropicales mostraron una mayor tasa de crecimiento en la última década, disminuyendo la brecha entre ambas regiones. Conclusión: Existe un sesgo regional en WoS y Scopus, que recuperan más artículos y citas sobre mamíferos paleárticos que sobre mamíferos neotropicales; este sesgo es peor en WoS y significa que se necesita un aumento urgente en la investigación indexada sobre especies neotropicales para estar al nivel de la investigación paleártica.

Global publication trends in ophthalmic genetics and gene therapy research: A Scientometric analysis / Tendências globais de publicação de pesquisas sobre genética oftálmica e terapia genética: uma análise cientométrica

ABSTRACT Objective: A scientometric analysis produced in ophthalmic genetics and gene therapy research is lacking. The purpose of this study is to present a holistic analysis of ophthalmic genetics literature. Methods: The data used in this study were obtained from the Web of Science (WoS) Core Collection. All published documents between 1975-2019 were included. The data exported from WoS enabled the extensive details of ophthalmic genetics related literature including countries, institutions, authors, citations and keywords. Scientometric network maps of keywords and also country and institution co-authorships were created with free software. Global contributions of the countries to the ophthalmic genetics literature were shown by a graphic. Results: The search query revealed a total of 2322 documents. Most of the documents were original articles (75.75%). USA was the leading country by producing 45.39% of all documents in ophthalmic genetics research followed by UK, Germany, China and France. Pennsylvania University was the most contributing institution in the literature (5.25%) followed by University College London and Moorfields Eye Hospital. The average citations per item was 29.4. The most used keywords over a 40-year period were 'family', 'cell', 'photoreceptor' and 'expression'. Conclusions: USA and UK dominated the ophthalmic genetics research. A substantial increase in the number of published documents in this field were observed after 2010.

COVID-19 meta-analyses: a scoping review and quality assessment / Metanálises sobre COVID-19: revisão de escopo e análise de qualidade

ABSTRACT Objective: To carry out a scoping review of the meta-analyses published regarding about coronavirus disease 2019 (COVID-19), evaluating their main characteristics, publication trends and methodological quality. Methods: A bibliometric search was performed in PubMed®, Scopus and Web of Science, focusing on meta-analyses about COVID-2019 disease. Bibliometric and descriptive data for the included articles were extracted and the methodological quality of the included meta-analyses was evaluated using A Measurement Tool to Assess Systematic Reviews. Results: A total of 348 meta-analyses were considered eligible. The first meta-analysis about COVID-19 disease was published on February 26, 2020, and the number of meta-analyses has grown rapidly since then. Most of them were published in infectious disease and virology journals. The greatest number come from China, followed by the United States, Italy and the United Kingdom. On average, these meta-analyses included 23 studies and 15,200 participants. Overall quality was remarkably low, and only 8.9% of them could be considered as of high confidence level. Conclusion: Although well-designed meta-analyses about COVID-19 disease have already been published, the majority are of low quality. Thus, all stakeholders playing a role in COVID-19 deseases, including policy makers, researchers, publishers and journals, should prioritize well-designed meta-analyses, performed only when the background information seem suitable, and discouraging those of low quality or that use suboptimal methods.

RESUMO Objetivo: Realizar uma revisão de escopo das metanálises publicadas sobre a doença pelo coronavírus 2019 (COVID-19), avaliando suas principais características, tendências de publicação e qualidade metodológica. Métodos: Uma busca bibliométrica foi realizada em PubMed®, Scopus e Web of Science, com foco em metanálises sobre a doença pelo COVID-19. Foram extraídos dados bibliométricos e descritivos dos artigos incluídos, e a qualidade metodológica foi avaliada usando a ferramenta A Measurement Tool to Assess Systematic Reviews. Resultados: Um total de 348 metanálises foram consideradas elegíveis. A primeira delas foi publicada em 26 de fevereiro de 2020, e, desde então, o número dessas publicações cresceu rapidamente. A maioria foi publicada em periódicos de infectologia e virologia. Grande parte é proveniente da China, seguida dos Estados Unidos, da Itália e do Reino Unido. Em média, as metanálises incluíram 23 estudos e 15.200 participantes. Em geral, a qualidade metodológica foi baixa, e apenas 8,9% delas podem ser consideradas de algum grau de confiabilidade Conclusão: Embora algumas metanálises bem conduzidas sobre a doença pelo COVID-19 tenham sido publicadas, a maioria apresenta baixa qualidade. Todos os envolvidos na abordagem da doença pelo COVID-19, incluindo formuladores de políticas, pesquisadores, editoras e periódicos, devem dar prioridade a metanálises de alta qualidade, realizadas apenas quando os dados são viáveis, e desencorajar as de baixa qualidade ou conduzidas com métodos subótimos.

Hotspots and trends of Ophiopogonis Radix based on CiteSpace knowledge map / 中国中药杂志

Ophiopogonis Radix is an important Yin-nourishing drug in traditional Chinese medicine(TCM), with the effects of nourishing Yin, promoting fluid production, clearing away heart-fire, and relieving restlessness. It is widely used in clinical practice due to its multiple chemical components and pharmacological effects. The technique "mapping knowledge domains" is an effective tool to quantitatively and objectively visualize the development frontiers and trends of certain disciplines. In this study, TCM research papers related to Ophiopogonis Radix were retrieved from Web of Science(WoS) and CNKI, and the research institutions, journals, and keywords involved were visualized and analyzed using the scientometric software CiteSpace. The co-occurrence network of related research on Ophiopogonis Radix was constructed, and the Ophiopogonis Radix-disease-target network was plotted using Cytoscape 3.8.2. The hot topics in Chinese and English papers were analyzed and the shortcomings in the research on Ophiopogonis Radix were summed up. Furthermore, the development trends were discussed. A total of 1 403 Chinese papers and 292 English papers were included in this study. The analysis of research institutions showed that Beijing University of Chinese Medicine and China Pharmaceutical University were the two research institutions with the largest numbers of papers published. The analysis of journals showed that Hebei Journal of Traditional Chinese Medicine and Journal of Asian Natural Products Research were the two journals with the highest numbers of papers concerning Ophiopogonis Radix. The keyword analysis showed that the research contents of Chinese papers focused on the analysis of medication regularity and clinical observation trials, while the English papers focused on component analysis and pharmacological investigation. Data mining and apoptosis-based pharmacological mechanism might be the research trends in the future.

Los estudios bibliométricos en el campo de la psicología iberoamericana: Una revisión metabibliométrica / The bibliometric studies in the field of Ibero-American psychology: A metabibliometric review

Resumen La bibliometría consiste en el tratamiento matemático y estadístico de la información científica y, por ello, se la concibe como la cuantificación de la información bibliográfica susceptible de ser analizada. Más allá de que algunos autores la conciban como una metodología y otros como una técnica, la bibliometría facilita la organización, selección y categorización de la información para un tratamiento cuantitativo y cualitativo. Desde hace más de tres décadas, los estudios bibliométricos han comenzado a proliferar con diferentes usos, orientaciones y aplicaciones en el campo de la psicología iberoamericana. En este trabajo se analizan los estudios bibliométricos en el campo de la psicología iberoamericana recuperados de tres bases de datos: Dialnet (España), Redalyc (México) y SciELO (Brasil). A partir de una muestra de 81 trabajos seleccionados, se realizó una categorización según las diferentes líneas de investigación, los autores más frecuentes, los países de los autores, el rango de años de las publicaciones, el idioma de las publicaciones, el género en la redacción de los trabajos, las revistas que más estudios bibliométricos publicaron y las más analizadas desde la perspectiva bibliométrica. También se analizó el contexto histórico de aparición de los estudios bibliométricos en el campo de la psicología de Iberoamérica. Se concluye que los estudios bibliométricos son un importante recurso metodológico para la evaluación de la disciplina y profesión psicológica, siempre que logren ir más allá de la mera descripción de datos cuantitativos y puedan complementarse con análisis cualitativos, lo que brindaría mayor potencialidad interpretativa y explicativa.

Abstract Bibliometry consists on the mathematical and statistical treatment of published scientific information. This methodology, or technique (following some authors), includes the quantification of bibliographic information that can be analyzed. Bibliometric and qualitative data reviews can be combined in order to offer high-quality conclusions. For more than three decades, bibliometric studies have proliferated with different uses, orientations, and applications in Ibero-American psychology. All the classic areas of psychology (basic psychological processes, clinical and health psychology, organizational and work psychology, educational psychology), as well as new areas, such as sports psychology, traffic psychology, consumer psychology, and others have been subject of bibliometric works. Several productions can be recognized where bibliometry is used for historical analysis, review of specialized literature, scientific journals analysis, and the recognition of different areas of research. The goal of this work is to provide a metabibliometric analysis, that is, a bibliometry of bibliometric studies. It is a descriptive study in which different documentary sources are retrieved, classified, and analyzed based on the proper procedure of bibliometric studies. This study examined the scientific and scholarly productions in the field of Ibero-American psychology, using three specific databases: Dialnet (Spain), Redalyc (Mexico), and SciELO (Brazil). The choice of such databases was because they provide the indexation of a large number of psychology journals and also allow free access to their contents, which gives some coverage to the psychological production of the Ibero-American region. The search was guided by the following general descriptors: "Bibliometric" and "Psychology", present in any of the search fields of these databases. These two words are functionally equivalent to detect items in Spanish and Portuguese (because all articles have abstracts in English). Interdisciplinary studies were ruled out, and those clearly outside of psychological science or the profession of psychology. The final refined sample of 81 articles were classified according to the following indicators: a) lines of research; b) more frequent authors; c) countries of the authors; d) range of years of publications; e) language of the publications; f) gender in the writing of the works; g) the journals that published the most bibliometric studies; and h) the most analyzed journals from the bibliometric perspective. The vast majority of articles are from the present century (70), which highlights the recent explosion of work in the field. For reference only, eight articles were published in the 1990s, 34 articles were published in the 2000s, and 36 articles were published in the current half-decade. The language of the articles is distributed as follows: 71 in Spanish (88 %), 5 in English (6 %), and 5 in Portuguese (6 %). The proportion by gender of correspondence authors reflects that 40 % are women (33 articles), and 60 % are men (48 articles), always considering the first signatory in cases of multiple authorship. The countries according to the correspondence author, taking the first author in the cases of multiple authorships, are: Spain (45), Colombia (15), Argentina (6), Brazil (5), Mexico (4), Chile (3), Peru (2) and Costa Rica (1). Results confirm that the bibliometric research design is a consistent methodological approach to evaluate the field of psychology as a discipline and a professional practice in Ibero-America. These results do not reflect the entire set of bibliometric research in Ibero-American psychology. However, they can also be considered as a representative map of bibliometric studies in the region. The most significant criticism that can be indicated for these bibliometric studies is the abusive descriptive perspective that appears in them. It would be desirable for this kind of research to incorporate other analytical perspectives to go beyond the purely descriptive, which could obtain greater interpretative and explanatory potential regarding what was investigated.

Mapeando a área de pensamento social no Brasil: uma análise preliminar de sua produção em artigos / Mapping the research field of social thought in Brazil: a preliminary analysis of its production in articles / Mapeando el área del pensamiento social en Brasil: un análisis preliminar de su producción en artículos

Este artigo busca responder a alguns dos desafios de sistematização, indexação e divulgação de variados documentos acadêmicos da área de pensamento social no Brasil pela Biblioteca Virtual do Pensamento Social (BVPS). Argumentamos que a importância da discussão sobre preservação digital para a BVPS cumpre dois objetivos: o de disponibilizar documentos digitalizados a um público mais amplo e o de mapear a produção contemporânea da área, com intuito de criar uma memória intelectual. Neste artigo, nos deteremos sobretudo no segundo objetivo, tendo em vista definir bem como disponibilizar ao público da biblioteca os critérios de seleção e organização do acervo. Dentro dos limites do recorte proposto, por meio de redes de acoplamento bibliográfico, cocitação e mapas semânticos, apresentaremos aqui uma análise preliminar da produção de artigos na área de pensamento social no Brasil. A atual pesquisa é fundamental para a definição das próximas etapas de ampliação do conteúdo da biblioteca, notadamente a definição de novos seletores de busca, a integração de novos autores e autoras à seção Intérpretes e a indexação de trabalhos com temáticas e abordagens caras à área de pensamento social no Brasil.

This article seeks to respond to some of the challenges of systematization, indexing and dissemination of various academic documents in the field of social thought in Brazil by the BVPS ­ Biblioteca Virtual do Pensamento Social (Virtual Library of Social Thought). We argue that the importance of the discussion on digital preservation for the BVPS fulfills two objectives: that of making digitized documents available to a wider audience and that of mapping contemporary production in that field in order to create an intellectual memory. In this article, we will focus mainly on the second objective, in order to define as well as make available to the library public the selection and organization criteria of the collection. Within the limits of the proposed clipping, we will present here a preliminary analysis of the production of articles in the field of social thought in Brazil through networks of bibliographic coupling, co-quotation and semantic maps. The current research is fundamental for the definition of the next steps to expand the content of the library, notably the definition of new search options the integration of new authors in the section Interpreters and the indexing of works containing important themes and approaches for the area of social thought in Brazil.
