Problems and perspectives of ophthalmic research in Germany: results from a national survey.
2013
<b><i>Purpose:</i></b> To identify and describe the most relevant obstacles to carrying out ophthalmic research in Germany. <b><i>Methods:</i></b> Two research methods were used to assess current problems in ophthalmic research. First, 55 expert interviews were conducted with major stakeholders in ophthalmic research, and key problems were identified. An online questionnaire was then sent to 3,080 German ophthalmologists, of whom 927 responded by evaluating the current research situation within ophthalmology in Germany. We devised a score to rank areas of concern by multiplying the responders' rate, ranging between -3 (‘I disagree completely')…
La colaboración interinstitucional en la producción científica española en Enfermería: análisis de redes sociales
2013
[EN]: [Objective]: The objectives of this paper are to analyze the Spanish scientific production in nursing, define its temporal evolution, its geographical and institutional distribution, and observe the interinstitutional collaboration. [Method]: We analyze a comprehensive sample of Spanish scientific production in the nursing area extracted from the multidisciplinary database SciVerse Scopus. [Results]: The nursing scientific production grows along time. The collaboration rate is 3.7 authors per paper and 61% of the authors only publish one paper. Barcelona and Madrid are the provinces with highest number of authors. Most belong to the hospitalary environment, followed closely by authors…
Scientific mapping of the research output on hypertension in children and adolescents, 2010-2018.
2021
Objective The area of pediatric hypertension (HTN) research has seen substantial progress over the last two decades, but no bibliometric analysis has yet been undertaken to describe these advances. This study aims to describe the published research examining HTN in children and adolescents from 2000 to 2018. Methods Articles were retrieved using PubMed and the Web of Science. Analyses were performed to quantify the evolution of scientific output, identifying the leading journals, authors, and countries as well as the existing collaboration networks. Likewise, we identified the most cited articles, describing their document type, main topic focus, and the age of the patients studied. Results…
Redes de colaboración y autorías científicas sobre la enfermedad de Chagas: análisis de las publicaciones indexadas en PubMed (1940-2009)
2012
Chagas disease is a chronic, tropical, parasitic disease, endemic throughout Latin America. The large-scale migration of populations has increased the geographic distribution of the disease and cases have been observed in many other countries around the world. To strengthen the critical mass of knowledge generated in different countries, it is essential to promote cooperative and translational research initiatives. We analyzed authorship of scientific documents on Chagas disease indexed in the Medline database from 1940 to 2009. Bibliometrics was used to analyze the evolution of collaboration patterns. A Social Network Analysis was carried out to identify the main research groups in the are…
A Bibliometric Analysis of Fragility Fractures: Top 50.
2021
Background and Objectives: The population is aging and fragility fractures are a research topic of steadily growing importance. Therefore, a systematic bibliometric review was performed to identify the 50 most cited articles in the field of fragility fractures analyzing their qualities and characteristics. Materials and Methods: From the Core Collection database in the Thomson Reuters Web of Knowledge, the most influential original articles with reference to fragility fractures were identified in February 2021 using a multistep approach. Year of publication, total number of citations, average number of citations per year since year of publication, affiliation of first and senior author, geo…

Quantitative methods in business history: An impossible equation?
2010
Abstract In this article we want to evaluate how often quantitative tools and methods were utilized in the two premier journals in business history in the 1990s. Thus we tap into an important methodological discussion among the post-Chandlerian business historians. We found that simpler quantitative tools were employed quite often, but not necessarily going much beyond that.Also, it became apparent that the most cited business history articles were often written by scholars coming from‘outside’ the fluid disciplinary core of business history field.The analyses performed in the article revealed that the level of quantification seemed to have either no discernible impact (Business History Rev…
