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…

How individual characteristics shape the structure of social networks

2015

Abstract We study how students’ social networks emerge by documenting systematic patterns in the process of friendship formation of incoming students; these students all start out in a new environment and thus jointly create a new social network. As a specific novelty, we consider cooperativeness, time and risk preferences – elicited experimentally – together with factors like socioeconomic and personality characteristics. We find a number of robust predictors of link formation and of the position within the social network (local and global network centrality). In particular, cooperativeness has a complex association with link formation. We also find evidence for homophily along several dim…

Who makes partner in Big 4 audit firms? – Evidence from Germany

2021

Abstract This study investigates who makes partner in Big 4 audit firms. Building on prior qualitative research, we conduct the first large scale study using archival data to examine the incremental importance of different individual auditor characteristics for making partner. For our analyses, we collect information on German auditors from a business-oriented social network site. We conduct a longitudinal analysis for a cohort of Big 4 senior managers and directors to identify determinants of making partner. We find that economic capital, social capital, and institutionalized cultural capital matter for making partner. Further, we find that female and foreign auditors are less likely to be…

Multimodal disinformation about otherness on the internet : the spread of racist, xenophobic and Islamophobic fake news in 2020

2021

This work studies the use of disinformation to construct an image of otherness through the internet. We applied a content analysis methodology to the 161 racist, xenophobic or Islamophobic fake news pieces that were discredited in 2020 by the four Spanish information verification media entities accredited by the International Fact-Checking Network: Maldita.es , Newtral , Efe Verifica and Verificat . The results show that the most commonly used formats were image and video, that disinformation was most often based on taking information out of context and deception, and that the source could not be identified. The most shared characteristics associated otherness with receiving aid, violence a…

DiDuSoNet: A P2P architecture for Ditributed Dunbar-based Social Networks,

2015

Online Social Networks (OSNs) are becoming more and more popular on the Web. Distributed Online Social Networks (DOSNs) are OSNs which do not exploit a central server for storing users data and enable users to have more control on their profile content, ensuring a higher level of privacy. In a DOSN there are some technical challenges to face. One of the most important challenges is the data availability problem when a user is offline. In this paper we propose DiDuSoNet, a novel P2P Distributed Online Social Network where users can exercise full access control on their data. Our system exploits trust relationships for providing a set of important social services, such as trustness, informati…

Epidemic diffusion of social updates in Dunbar-based DOSN

2014

Distributed Online Social Networks (DOSNs) do not rely on a central repository for storing social data so that the users can keep control of their private data and do not depend on the social network provider. The ego network, i.e. the network made up of an individual, the ego, along with all the social ties she has with other people, the alters, may be exploited to define distributed social overlays and dissemination protocols. In this paper we propose a new epidemic protocol able to spread social updates in Dunbar-based DOSN overlays where the links between nodes are defined by considering the social interactions between users. Our approach is based on the notion of Weighted Ego Betweenne…

Drivers affecting the adoption and effectiveness of social media investments: The Italian wine industry case

2019

Purpose The purpose of this paper is twofold: first, to identify distinct organisational models in a sample of firms operating in the wine industry; and second, to identify the main internal resources that characterise those firms most motivated towards the adoption of social media (SM) tools and those that perceive SM investment as more effective. Design/methodology/approach The empirical investigation was carried out by administering an online questionnaire to a sample of 82 Sicilian wineries. The principal component analysis was used to identify latent factors that drive managers to invest in SM technologies and to measure the impact perceived by managers. Subsequently, a cluster analys…

Pårørendes erfaringer med bruk av frivillige ved alvorlig sykdom i hjemmet

2017

Next-of-kins’ experiences when using volunteers for palliative patients living at home The aim of this study was to illuminate next-of-kins’ experiences when using volunteers supplementing community health care services for palliative patients living at home. The study has a qualitative approach. Nine individual interviews were conducted with next of kin from a municipality in Southern Norway. Use of volunteers for palliative care in the home was a relief for next-of-kin, especially prominent for families who had limited social network. Planned volunteering resulted in the best results. Use of volunteer was also found helpful for families as they were given a "breathing space" and a certain…
