La colaboración científica: principales líneas de investigación y retos de futuro
2014
The construction of knowledge is a collaborative process that has seen a dramatic growth over recent decades, since almost all research activities now involve increasing numbers of researchers, institutions, disciplines and countries. The present study provides a bibliographic review of the literature on research collaboration and identifies pioneering work on the topic, the types of studies undertaken and the variables analyzed. Several approaches are discussed: the “classical” approach, based on bibliometric indicators, which has taken on a new dimension with Social Network Analysis; and quantitative and qualitative approaches, which attempt to investigate the motivations and dynamics of …
El clima social del aula entre los alumnos repetidores con sus compañeros a través de Agent SocialMetric
2015
En este articulo describiremos una plataforma computacional web, denominada Agent SocialMetric que simplifica al docente la obtencion, gestion y muestra del clima del aula dado por el grado y estructura de las relaciones de los alumnos en la clase, a traves de un agente de interfaz conversacional llamado Albert, con el que el docente interactua en lenguaje natural. Agent SocialMetric posibilitara que los docentes conozcan a los alumnos a traves de sus relaciones reticulares, estableciendo la estructura social de la clase. Circunscribiremos la aplicacion a un caso practico en el ambito de Educacion Secundaria y conoceremos el clima social de la clase donde hay alumnos repetidores y determina…
Beyond the Family and the Household: Occupational Family Networks
2009
Although families and kinship have been studied extensively from a historical perspective, less attention has been paid to their significance and role in the formation of local social networks.This study makes use of extensive Finnish records of godparentage to map local networks to analyze the factors (kinship, work relations, neighborhood, friendship) that influenced their formation. It argues that, in the context of a closed industrial community, occupation and kinship were the major cornerstones of these networks. Only after work-related inequality was slowly eliminated in the early twentieth century did kinship begin to gain ground as the main influencing factor.
Network position and innovation capability in the regional innovation network
2019
This paper investigates the positioning of actors characterized by different natures in a regional innovation network and explores how these actors improve their innovation capabilities by assuming prominence or brokering positions. Innovation capability is widely seen to be the driving force in building regional competitive advantage, therefore investigating how the positioning of actors improves their innovation-related activities is relevant in terms of regional competitiveness. This paper builds on a survey conducted on the Sicilian regional area in Italy. A questionnaire was used to collect data concerning the relationships established between actors and the extent to which these relat…
Analyzing Online Social Support Networks. The Case of Italian Time Banks on Facebook
2019
With the advent of the Internet, social support has changed in nature and size, and new forms of social help have emerged, that reshaped the meaning of this concept. In the last years, social support has been mainly investigated within the theoretical framework of relational sociology, using network analysis techniques (Crossley, 2011; Donati, 2011; Mische, 2011; Tronca, 2013). An interesting expression of social support networks and civic engagement is the phenomenon of time banks that has had a broad diffusion in the mid-1990s, after important changes in postindustrial society. These organizations are now trying to exploit the potential of the Internet and social networking sites as a mea…
The Spanning Tree based Approach for Solving the Shortest Path Problem in Social Graphs
2016
Nowadays there are many social media sites with a very large number of users. Users of social media sites and relationships between them can be modelled as a graph. Such graphs can be analysed using methods from social network analysis (SNA). Many measures used in SNA rely on computation of shortest paths between nodes of a graph. There are many shortest path algorithms, but the majority of them suits only for small graphs, or work only with road network graphs that are fundamentally different from social graphs. This paper describes an efficient shortest path searching algorithm suitable for large social graphs. The described algorithm extends the Atlas algorithm. The proposed algorithm so…
Current trends in scientific research on global warming: A bibliometric analysis
2019
[EN] The objective of this paper is to contribute to a better understanding of the scientific knowledge in global warming, as well as to investigate the evolution of the research knowledge through the published papers included in Web of Science database. A bibliometric and social network analyses was performed to obtain indicators of scientific productivity, impact and collaboration between researchers, institutions and countries. A subject analysis was also carried out taking into account the key words assigned to papers and subject areas of journals. A number of 1,672 articles were analysed since 2005 until 2014. The most productive journals were Journal of Climate (n = 95) and the most f…

A Study of the Bibliometry and Areas of the Research Groups of Archivos de Bronconeumología (2003–2007)
2010
Introduction Scientific cooperation is essential for the advance of biomedical research. Scientists set up informal groups to work together on common issues, who are the main units in the research funding system. Bibliometric and Social Network Analysis methods allow informal groups in scientific papers to be identified and characterised. The objective of the study is to identify research groups in Archivos de Bronconeumologia between 2003 and 2007 period with the aim of characterizing their scientific collaboration patterns and research areas.
