Detecting research fronts in OLED field using bibliographic coupling with sliding window

The Methodological Basis of Defining Research Trends and Fronts

The methodological and technical aspects of identifying research fronts and trends in the development of science are considered. Based on the literature data, a comparison of scientometric methods for finding research fronts was carried out: analysis of publication activity, direct citation analysis, co-citation analysis, bibliographic coupling, and content analysis. The advantages of the combined application of various approaches are shown, the role of expert assessment and verification of the results of scientometric analysis is emphasized. We revealed topical problems associated with the detection of scientific fronts by scientometric methods and showed promising directions in their solution.

Análisis bibliométrico de la Revista Española de Documentación Científica desde su inclusión en la Web of Science (2008-2018)

En este trabajo se presenta un análisis bibliométrico del contenido científico de la Revista Española de Documentación Científica durante el periodo 2008-2018, usando como metodología el análisis de rendimiento y los mapas de la ciencia. En los resultados se muestran, por un lado, algunos de los indicadores bibliométricos de rendimiento básicos, como son: número de documentos publicados, citas obtenidas, evolución del Factor de Impacto, Índice-h, así como los autores más productivos y más citados y la distribución geográfica de las publicaciones. Por otro lado, este análisis muestra la evolución conceptual de la revista basada en los mapas de la ciencia. En la discusión se comparan estos resultados con otros estudios anteriores, que existen sobre la revista, de evolución temática, y sobre la documentación a nivel nacional e internacional. Se concluye indicando cuales son los autores, países y las dos grandes áreas temáticas que destacan en esta revista: bibliometría y web.

Bibliometric analysis of core journals which publish articles of physical therapy on aging

OBJECTIVE

Increase in population's longevity has led to considerable efforts worldwide on physical therapy aging research. The aim of this study is to identify which are the main scientific journals, as well as the most productive authors, institutions and keywords related to the journals, that have published about physical therapy and aging.

METHODS

Original articles published from 1990 to 2014 were retrieved from the bibliographic database Science Citation Index Expanded of Web of Science Core Collection. After standardization of the bibliographic information, a series of bibliometric indicators was obtained regarding authors, institutions, citation and keywords of the core journals using bibliometric software. The PAJEK network analysis program was used for graphic representation.

RESULTS

A total of 2,237 original articles are included in this analysis. The number of identified journals is 573, with an average growth of publishing journals throughout the studied period of 9.41%. Bradford's distribution shows 12 core journals, out of which 41.67% have published constantly all throughout the 25-year period, being the most productive one Physical Therapy. Fritz, Julie M is the most productive author, and University of Sydney the most productive institution. The keyword exercise is used in an outstanding way.

CONCLUSIONS

The productivity trends provided an indication of the greater scientific interest of physical therapy in aging as a line of research. Collectively, the data indicated that physical therapy-specific journals are being consolidated but non-specific are still a significant research source, and that a fundamental element of their research includes exercise and movement.

Worldwide research output trends on drinking and driving from 1956 to 2015

This study seeks to analyze worldwide research activity on drinking and driving of macro-actors (countries and research fields) and meso-actors (institutions, journals, articles, co-substance(s) studied) during the last 6 decades (between 1956 and 2015). Web of Science and Elsevier Scopus were searched using terms referred to drinking and driving, including terms related to vehicles and way spaces. Overlapping was excluded and absence of false positives was confirmed. Articles on alcohol with/without other psychoactive substances were assessed quantitatively (bibliometric measures). Well identified by All Science Journal Classification system (ASJC) (Elsevier Scopus), an increase in the number of articles through the 6 decades analyzed was observed, from 152 (1956-1965) to 2302 (2006-2015), which represent an average decadal growth rate (ADGR) of 72.21. Among 89 countries, United States of America published 37.62 % out of all the included articles. Nevertheless, institutions from Canada, European Union and Australia published 50 articles or more during 60 years. The publications were mostly welcomed by journals on substance abuse research, and an exponential increase in publications on combined use of alcohol and other driving-impairing substances was observed since the second half of the eighties. This is the first study that attempted an analysis of scientific production of macro- and meso-actors on a topic belonging to an intricate research area. Bibliometric analyses should be considered as an important tool for updating the evidence on the serious problem of driving under the influence (DUI). The awareness of policy makers and the other relevant actors involved in the control of DUI of alcohol and other substances is stressed.

Discovering thematic change and evolution of utilizing social media for healthcare research

Background

Social media plays a more and more important role in the research of health and healthcare due to the fast development of internet communication and information exchange. This paper conducts a bibliometric analysis to discover the thematic change and evolution of utilizing social media for healthcare research field.

Methods

With the basis of 4361 publications from both Web of Science and PubMed during the year 2008–2017, the analysis utilizes methods including topic modelling and science mapping analysis.

Results

Utilizing social media for healthcare research has attracted increasing attention from scientific communities. Journal of Medical Internet Research is the most prolific journal with the USA dominating in the research. Overly, major research themes such as YouTube analysis and Sex event are revealed. Themes in each time period and how they evolve across time span are also detected.

Conclusions

This systematic mapping of the research themes and research areas helps identify research interests and how they evolve across time, as well as providing insight into future research direction.
