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 User-Centered Chatbot (Wakamola) to Collect Linked Data in Population Networks to Support Studies of Overweight and Obesity Causes: Design and Pilo…
2021
[EN] Background: Obesity and overweight are a serious health problem worldwide with multiple and connected causes. Simultaneously, chatbots are becoming increasingly popular as a way to interact with users in mobile health apps. Objective: This study reports the user-centered design and feasibility study of a chatbot to collect linked data to support the study of individual and social overweight and obesity causes in populations. Methods: We first studied the users' needs and gathered users' graphical preferences through an open survey on 52 wireframes designed by 150 design students; it also included questions about sociodemographics, diet and activity habits, the need for overweight and o…
Literatura científica de autores españoles sobre análisis de citas y factor de impacto en Biomedicina (1981-2005)
2008
This paper analyses the development of Spanish research literature in the field of citation analysis and impact factor (IF) in biomedicine over the period 1981-2005. Bibliometric methods and social network analysis were used to examine papers indexed in the Science Citation Index-Expanded (SCI-Expanded), Social Sciences Citation Index (SSCI), MEDLINE, Índice Médico Español (IME) and Índice de Ciencias Sociales y Humanidades (ISOC) databases. 184 papers were identified, 79.89% of which were original research articles. Only four of these papers had been published before the 1990s. The mid 1990s saw a remarkable increase in the number of papers published (8-14 papers/year) with the highest pro…
User Innovation Networks and Research Challenges
2009
User Innovation Networks (UIN) has been considered the open innovation model for this century as it functions entirely independently of manufacturers. This paper discusses two UIN cases, Daz3D, as well as Linux Dell and IBM cooperation as regards research challenges about the community of practice and interface used. It concludes that current technology only now started touching global and extreme collaboration for creativity and innovation.
Engagement as a Driver of Growth of Online Health Forums: Observational Study
2017
Background: The emerging research on nurturing the growth of online communities posits that it is in part attributed to network effects, wherein every increase in the volume of user-generated content increases the value of the community in the eyes of its potential new members. The recently introduced metric engagement capacity offers a means of quantitatively assessing the ability of online platform users to engage each other into generating content; meanwhile, the quantity engagement value is useful for quantifying communication-based platform use. If the claim that higher engagement leads to accelerated growth holds true for online health forums (OHFs), then engagement tracking should be…
The most 100 cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. A bibliometric cross-sectional analysis
2021
The number of citations a peer-reviewed article receives is often used as a measure of its importance and scientific impact. This paper identifies, describes and categorizes the highly cited papers in addiction research on cannabis, heroin, cocaine and psychostimulants. Highly cited papers were identified in the Web of Science Core Collection database. Several bibliometric indicators were calculated. Social network analysis was applied to draw groups of authors and institutions with the greatest number of collaborations and co-words. The number of citations for the top 100 cited articles ranged from 649 to 4,672. The articles were published in 40 journals. The subject category Substance Abu…
Evolution of coauthorship networks: worldwide scientific production on leishmaniasis.
2013
Introduction Collaboration is one of the defining features of contemporary scientific research, and it is particularly important with regard to neglected diseases that primarily affect developing countries. Methods The present study has identified publications on leishmaniasis in the Medline database from 1945 to 2010, analyzing them according to bibliometric indicators and statistics from social network analysis. Examining aspects such as scientific production, diachronic evolution, and collaboration and configuration of the research groups in the field, we have considered the different types of Leishmania studied and the institutional affiliation and nationality of the authors. Results Se…
The spanning tree based approach for solving the shortest path problem in social graphs
2016
This thesis is devoted to the shortest path problem in social graphs. Social graphs represent individuals and social relationships between them. As for social networking sites, their users are represented as vertices of the social graph, and the relationship which indicates whether two users are friends in the social networking site are represented as edges of the social graph. Therefore, social graphs are widely investigated by sociologists in order to determine rules and properties of various social processes. Analysis of such social graphs may be used in prediction of results of election, or recommendation systems. Calculation of many social graph metrics requires computation of shortest…
Estrategias basadas en análisis de redes sociales para optimizar el clima de aprendizaje en la universidad
2021
The aim of this study was to detect leaders among a group of university students based on their centrality scores and, from these scores, to distribute roles to help enhance learning climate. We understood that learning climate improved when the construction of networked knowledge was stimulated from the perspective of Computer-Supported Collaborative Learning. We conducted the educational experiment in a virtual environment. An online discussion forum was set up in a loo- sely structured format, and the students’ centrality scores were calculated from the social network they generated in the forum. Our findings show that student connectivity increased significantly and that several leaders…
