RESUMO

BACKGROUND: Fungal keratitis is one of the leading causes of ocular morbidity. The prognosis of fungal keratitis is poorer than many other forms of keratitis but the research of which relatively lags behind. We conducted a bibliometric and visualized analysis in order to characterize the overall status, general trends and current foci of keratomycosis research field. METHODS: Literature database ranged from 1959 to 2019 was obtained from web of science core collection and analyzed by Citespace and VOSviewer software. RESULTS: A total of 1906 papers of fungal keratitis were retrieved and derived a 27,917 references document set. The number of publications increased rapidly in past 30 years. Cornea was the journal published most papers of keratomycosis. The leading countries were United States of America (USA), India and Peoples Republic of China (PRC), from where came the most productive and most cited institutions and authors. Co-cited reference analysis revealed the most cited manuscripts were concerned about epidemiology or spectrum. Lens-associated Fusarium, amphotericin B, voriconazole, corneal cross-linking, predisposing factor are some of the high frequency topics in clustered co-cited reference analysis and co-occurrence keywords analysis. Burst detection analysis of keywords showed ocular drug delivery was the new research foci. CONCLUSION: From this study, we received an overall view to the current status, trends and hot spots of fungal keratitis research field. Visualized bibliometric analysis is an efficient way for literature learning and useful for future researchers.

RESUMO

In the current pandemic times, medical physicists may not be aware that there is an interesting story on two significant discoveries related to the coronavirus. One is the invention of the polymerase chain reaction (PCR) and the other is the first electron microscopic observation and identification of the coronavirus. Both of them were disregarded by the reviewers and major journals declined to publish these discoveries. These days, PCR, for example, is a widespread method for analyzing DNA, having a profound effect on healthcare, especially now during the Covid-19 pandemic. Prejudice or perhaps ignorance prevail in every aspect of our society, and there is no exception in scientific research. We need to, however, learn from these two stories and be open-minded about novel discoveries and findings - as they may be just disruptive in the "right" way to lead to an unexpected breakthrough.

RESUMO

We propose a method to measure the potential scholarly impact of researchers based on network structural variations they introduced to the underlying author co-citation network of their field. We applied the method to the information science field based on 91,978 papers published between 1979 and 2018 from the Web of Science. We divided the entire period into eight consecutive intervals and measured structural variation change rates (ΔM) of individual authors in corresponding author co-citation networks. Four types of researchers are identified in terms of temporal dynamics of their potential scholarly impact-1) Increasing, 2) Decreasing, 3) Sustained, and 4) Transient. The study contributes to the understanding of how researchers' scholarly impact might evolve in a broad context of the corresponding research community. Specifically, this study illustrated a crucial role played by structural variation metrics in measuring and explaining the potential scholarly impact of a researcher. This method based on the structural variation analysis offers a theoretical framework and a practical platform to analyze the potential scholarly impact of researchers and their specific contributions.

RESUMO

INTRODUCTION: Research productivity has been linked to a country's intellectual and economic wealth. Further analysis is needed to assess the association between the distribution of research across disciplines and the economic status of countries. METHODS: By using 55 years of data, spanning 1962 to 2017, of Elsevier publications across a large set of research disciplines and countries globally, this manuscript explores the relationship and evolution of relative research productivity across different disciplines through a network analysis. It also explores the associations of those with economic productivity categories, as measured by the World Bank economic classification. Additional analysis of discipline similarities is possible by exploring the cross-country evolution of those disciplines. RESULTS: Results show similarities in the relative importance of research disciplines among most high-income countries, with larger idiosyncrasies appearing among the remaining countries. This group of high-income countries shows similarities in the dynamics of the relative distribution of research productivity over time, forming a stable research productivity cluster. Lower income countries form smaller, more independent and evolving clusters, and differ significantly from each other and from higher income countries in the relative importance of their research emphases. Country-based similarities in research productivity profiles also appear to be influenced by geographical proximity. CONCLUSIONS: This new form of analyses of research productivity, and its relation to economic status, reveals novel insights to the dynamics of the economic and research structure of countries. This allows for a deeper understanding of the role a country's research structure may play in shaping its economy, and also identification of benchmark resource allocations across disciplines for developing countries.

RESUMO

INTRODUCTION: Venous thromboembolism (VTE) in children not only imposes a heavy burden on the medical resources and economy of the society, but also seriously affects the growth and development of children, even threaten children's lives. A large number of publications have been performed in this field in recent years. In this bibliometric analysis, publications on VTE in children were examined and analyzed to explain the present research hotspots. METHODS: Articles related to VTE in children published in the PubMed database from 1988 to June 18, 2019 were selected as the research sample. BICOMB software was used to retrieve the annual publications, journals, journal source countries and the high-frequency major medical subject headings (MeSH) terms on the articles. Then, the co-word matrix was constructed by BICOMB using the selected high-frequency MeSH terms. Next, gCLUTO software was used to analyze the matrix by double clustering and visual analysis in a strategy of hotspot identification. In addition, CiteSpace software was used to perform the knowledge map of co-authors to explore the core authors. RESULTS: One thousand seven hundred seventy-nine articles on VTE in children were obtained. Seven hundred ninety academic journals distributed in 58 countries have published articles on VTE in children, and the developed countries and the United States were the major force in the journal source countries. Nowak-Göttl U occupied an important position in this field. We constructed a co-word matrix composing of 37 high-frequency MeSH terms, generated visual matrix and visual hill, and classified the hot-spots into 5 aspects based on 8 categories. CONCLUSION: The results show that the research trend of children's VTE has been increasing gradually, and the sound achievement has been obtained in these hotspots in relation to the area of inherited thrombophilia, prevention and control, treatment, diagnosis, prevalence, risk factors, and complication study. However, there is a lack of communication and cooperation in this field, and the gap of national and regional research results is huge. To sum up, this study provides evidence and guidance for researchers, clinicians, and educators.

RESUMO

Literature-based Discovery (LBD) aims to discover new knowledge automatically from large collections of literature. Scientific literature is growing at an exponential rate, making it difficult for researchers to stay current in their discipline and easy to miss knowledge necessary to advance their research. LBD can facilitate hypothesis testing and generation and thus accelerate scientific progress. Neural networks have demonstrated improved performance on LBD-related tasks but are yet to be applied to it. We propose four graph-based, neural network methods to perform open and closed LBD. We compared our methods with those used by the state-of-the-art LION LBD system on the same evaluations to replicate recently published findings in cancer biology. We also applied them to a time-sliced dataset of human-curated peer-reviewed biological interactions. These evaluations and the metrics they employ represent performance on real-world knowledge advances and are thus robust indicators of approach efficacy. In the first experiments, our best methods performed 2-4 times better than the baselines in closed discovery and 2-3 times better in open discovery. In the second, our best methods performed almost 2 times better than the baselines in open discovery. These results are strong indications that neural LBD is potentially a very effective approach for generating new scientific discoveries from existing literature.

RESUMO

Hoy en día, la comunicación científica se está viendo enriquecida debido a la utilización de nuevos modos de almacenamiento, publicación y difusión de los resultados. Entre ellos se encuentran las denominadas plataformas de perfiles académicos, dentro de las cuales se encuadrarían Scopus author ID, ORCID, Publons y Kudos y, por otro lado, las redes sociales de investigación, entre las que se incluirían ResearchGate, Academia.edu y Google Scholar citations. Estas herramientas tienen como principal objetivo aumentar la visibilidad e impacto de los contenidos y publicaciones. Son páginas web multidisciplinares que contienen perfiles investigadores individuales con hipervínculos en red a revistas, bases de datos y otras fuentes. En algunos casos incluyen indicadores bibliométricos, que permiten medir el impacto causado por un trabajo a partir de la literatura. En este artículo se comparan las principales plataformas online, así como algunas de las redes sociales de investigación que existen hoy día para la creación de perfiles de investigación


Nowadays, scientific communication is enriched by the use of new ways of storing, publishing and disseminating research findings. Said new ways of scientific communication are known as the so-called academic profile platforms, which include Scopus author ID, ORCID, Publons and Kudos and on the other hand-social research networks, including ResearchGate, Academia.edu and Google Scholar citations. These tools have a main objective: enhancing both visibility and impact of contents and publications. They are multidisciplinary web pages that contain individual research profiles with network hyperlinks to magazines, databases and other sources. In some cases, bibliometric indicators are included, which allow measuring the impact caused by studies based on literature. This study compares the main online platforms, as well as some of the social research networks that currently exist for the creation of research profiles

RESUMO

Scholarly communication in science, technology, and medicine has been organized around journal-based scientific publishing for the past 350 years. Scientific publishing has unique business models and includes stakeholders with conflicting interests-publishers, funders, libraries, and scholars who create, curate, and consume the literature. Massive growth and change in scholarly communication, coinciding with digitalization, have amplified stresses inherent in traditional scientific publishing, as evidenced by overwhelmed editors and reviewers, increased retraction rates, emergence of pseudo-journals, strained library budgets, and debates about the metrics of academic recognition for scholarly achievements. Simultaneously, several open access models are gaining traction and online technologies offer opportunities to augment traditional tasks of scientific publishing, develop integrated discovery services, and establish global and equitable scholarly communication through crowdsourcing, software development, big data management, and machine learning. These rapidly evolving developments raise financial, legal, and ethical dilemmas that require solutions, while successful strategies are difficult to predict. Key challenges and trends are reviewed from the authors' perspective about how to engage the scholarly community in this multifaceted process.

RESUMO

This article explores the development of LGBTQ studies and scholarship in Bulgaria. In part, it brings to the forefront the personal experiences of some of the first Bulgarian scholars working on LGBTQ studies. The personal is interpreted in part through explorations of Bourdieu's concept of "symbolic violence." Elaborating on the challenges regarding the emergence and the development of LGBTQ studies on an institutional and personal level, I discuss three main topics: (1) the emergence and the development of LGBTQ scholarship and university courses in Bulgaria; (2) the main institutional obstacles and the "symbolic violence" within the academia against scholars dealing with LGBTQ subjects, including issues of funding, evaluation, and discrimination; and (3) the future development of the subject in Bulgaria, with a particular attention to the need for "LGBTQ studies solidarity" to overcome the disadvantaged position of LGBTQ scholars in post-socialist countries.
