Transnational Social Network Analysis
2012
AbstractThe following article discusses methods of social network analysis (SNA) as an approach in researching transnational social formations. SNA allows transnationality to be studied through relationships between actors, enabling the investigation of social structures which expand nation-state frameworks. Two empirical examples are used to address the central characteristics of the network analysis approach (focus on relations, systematic collection of data, means of visualising network data) and their relevance for research on cross-border social phenomena. The article also investigates the significance of geographical mobility in the research process, culminating in reflection on how “…
Sustainable development goals research in higher education institutions: An interdisciplinarity assessment through an entropy-based indicator
2022
Since 2015, the United Nations has urged higher education institutions (HEIs) to adopt an interdisciplinary approach towards the Sustainable Development Goals (SDGs). In other words, universities are encouraged to transcend any single disciplinary perspective in exploring sustainable development issues. This study examines the importance of driving the scientific production of HEIs towards the SDGs as a concrete institutional contribution to sustainable development. While bibliometric tools for the SDGs are currently emerging, the existing models have not focused on interdisciplinarity or on their usefulness as decision-management tools to drive SDG-related research at a micro-scale (i.e. t…
Mapping the scientific research on wine and health (2001-2011)
2013
[EN] There have been a substantial number of studies suggesting possible health benefits from polyphenols in wine, especially red wine. These hypothetical effects, in addition to those of alcohol, are attributed by many to antioxidant and antiinflammatory effects of the polyphenols. The aim of this paper was to map the scientific research on wine and health by using bibliographic analyses of papers published during the period 2002−2011. Papers were published in 535 different journals and in 106 different subject categories, the most productive journals being the Journal of Agricultural and Food Chemistry, Food Chemistry and Molecular Nutrition, and Food Research, and the most productive sub…
Redes, complejidad y Arqueología: otra forma de ver el pasado
2018
La ciencia moderna se ha benefi ciado de los intentos del positivismo y neopositivismo por explicar el mundo sensible, que han generando grandes avances en el mundo de la ciencia, pero que han tenido problemas a la hora de plantear una “Teoría del Todo”. Hay que destacar el hecho de que toda explicación de la realidad es siempre un modelo simplifi cado, que se basa en alguna teoría. Durante los años 90, con el fi n de avanzar en la comprensión de la realidad empírica, comenzaron su andadura lo que se conoce co mo Ciencias de la Complejidad. A través de ellas se pretende explicar una serie de fenómenos comúnes a todos los sistemas formados por elementos interrelacionados, que como un conjunt…
Analysis of network rumor dissemination and control mechanisms on Chinese social network : Sina Weibo
2016
The social network has become a major source of information. The openness and swiftness of the network bring instant accessing to both true and false information. Sometimes the false information such as network rumors can mislead people from obtaining the true information and even create chaos. The social network platforms and the governments in different countries are making effort on enacting their own mechanisms to strive on eliminating the rumors. The aim of this thesis is to investigate the spreading of rumors on the Chinese social networking website Sina Weibo. The censorship policy of the Chinese government and the methods used to control the spreading of rumors are discussed. The la…
Exploring learning analytics on YouTube: a tool to support students interactions analysis
2021
YouTube is a free online video-sharing platform that is often used by students for their learning activities. The interactions of the students when using the platform to shape new concepts, are worth to be investigated to better understand and to optimize the learning opportunities that take place in this platform. In this paper, we investigate which types of data are relevant to analyse the interactions of students with content on YouTube, and we introduce a new tool that emulates students’ interactions with the platform in order to provide data to be used in supporting Learning Analytics approaches. Our preliminary study inspects the tool effectiveness in data collection and analyses the …
Desarrollo, territorio y capital social. Un análisis a partir de dinámicas relacionales en el desarrollo rural
2013
Si bien parece ampliamente aceptada la idea de que una de las principales fuentes de capital social son las redes sociales, llama mucho la atención la escasez de estudios que utilizan el Análisis de Redes Sociales (ARS) para profundizar en el análisis y medición del capital social. Esto es especialmente significativo si tenemos en cuenta la ingente cantidad de publicaciones que existen sobre este concepto. El propósito de este trabajo es llevar a cabo una aproximación al potencial del análisis de redes sociales (ARS) para analizar la presencia y formas de capital, en concreto, en el marco de las agrupaciones para el desarrollo rural (Grupos LEADER), y en su valor complementario a otras técn…
Italian Amateur Pop-Rock Musicians on Facebook
2017
This chapter investigates how and why amateur musicians use social networking sites, employing a mixed-methods approach. Attention is focused on four big Italian Facebook communities of pop-rock musicians: drums, bass, guitar, and keyboard players (overall, 2,101 active users), analyzing the relational and textual data extracted from the web. The chapter analyzes the network structures emerging from the interactions among the users. It also identifies and maps the main areas of discussion (sound shaping, studio recording, marketplace, musical references, computer production, and relations) and the latent semantic dimension characterizing Facebook users’ activities, through social network an…
What do we do when we analyse the temporal aspects of computer-supported collaborative learning? A systematic literature review
2021
To better understand the premises for successful computer-supported collaborative learning (CSCL), several studies over the last 10 years have analysed the temporal aspects of CSCL. We broadly define the temporal aspects of CSCL as focusing on the characteristics of or interrelations between events over time. The analysis of these aspects, however, has been loosely defined, creating challenges regarding the comparability and commensurability of studies. To address these challenges, we conducted a systematic literature review to define the temporal analysis procedure for CSCL using 78 journal papers published from 2003 to 2019. After identifying the key operations to be included in the proce…
Peer selection and influence : Students’ interest-driven socio-digital participation and friendship networks
2020
Digital technologies have been increasingly embedded in students’ everyday lives. Interest-driven socio-digital participation (ISDP) involves students’ pursuit of interests mediated by computers, social media, the internet, and mobile devices’ integrated systems.ISDPis likely to intertwine closely with young people’s social networks that has been scarcely studied quantitatively. To close this gap, the present paper investigated students’ peer selection and influence effects of the intensity of their ISDP and friendship networks. We collected two-wave data by administering a peer nomination to trace students’ friendship networks with peers and a self-reported questionnaire to examine student…
