Regional Mobility Spaces? Visa Waiver Policies and Regional Integration
2016
Visa policies today are a central instrument for filtering wanted and unwanted types of travellers, leading to a hierarchy of mobility rights. While there is evidence of a “global mobility divide”, we still know little about the role of regional integration when it comes to the distribution of mobility rights and the (re)structuring of mobility spaces. Against this background, the paper examines the structure of visa relations in different bodies of regional integration (EU, MERCOSUR, ASEAN, ECOWAS, EAC, NAFTA, SADC and SICA). In this article, we compare visa policies in the member states of these institutions in 1969 and 2010 from a social network perspective. While one would generally exp…
Estilos de gestión de los perfiles políticos en Twitter: imagen y texto en las cuentas de los partidos en la campaña del 26J
2019
En este trabajo analizamos dos aspectos de las cuentas de los partidos políti - cos en Twitter durante la campaña del 26J: la estructura semiótica de los tuits y su función comunicativa. El análisis de estas dos varia - bles permite concluir que 1) las cuentas de los partidos carecen en general de voz insti - tucional y tienen sobre todo carácter ecoico respecto a las cuentas de los líderes, espe - cialmente los candidatos; 2) existe equilibrio entre el uso de texto e imagen; 3) la función predominante es el tuit de cita; 4) las cuentas son uniformes, solo destaca la de IZQUIER - DA UNIDA por su alto índice de especta - cularización de la política. No hay, en defi - nitiva, un estilo de ges…
Academic Contest and Social Networking to Promote Technology and Information Literacy among University Students
2012
Abstract Spanish universities have recently adapted their studies to the requirements of the European Higher Education Area (EHEA). This process has involved the consideration of the development of computer and informational skills as an academic objective. In order to develop these skills, among other activities, an informative video has been disseminated. The design of the communication campaign, developed through viral marketing and social networks has been the result of and empirical research carried out by students of the University of Valencia. This paper describes the research objectives, questions, techniques and main findings.
Modeling the Effects of Religious Belief and Affiliation on Prosociality
2021
To what extent do supernatural beliefs, group affiliation, and social interaction produce values and behaviors that benefit others, i.e., 'prosociality'? Addressing this question involves multiple variables interacting within complex social networks that shape and constrain the beliefs and behaviors of individuals. We examine the relationships among some of these factors utilizing data from the World Values Survey to inform the construction of an Agent-Based Model. The latter was able to identify the conditions under which – and the mechanisms by which – the prosociality of simulated agents was increased or decreased within an “artificial society” designed to reflect real world parameters. …
Superintendent Leadership in Hierarchy and Network
2015
School superintendents are coupled hierarchically with the top apex of municipality organization through their membership of leadership teams and through personal ties to the top municipal manager, which provides opportunities to take part in strategic decision-making processes beyond the educational sector. Superintendents are also vertically linked to their school leaders through strong and dense network ties. Along the horizontal axis superintendents are active network players with peers, for example through superintendent associations or more frequently mentioned through personal ties to superintendent colleagues. Superintendents are linked to school boards through strong formal ties. I…
Authenticity and well-being on social network sites: A two-wave longitudinal study on the effects of online authenticity and the positivity bias in S…
2014
In offline settings, authentic behavior has frequently been linked to increased well-being. Social network sites (SNSs) provide a new venue for authenticity, yet the effects of online authenticity are largely unknown. The present study investigated the reciprocal effects of authenticity on SNSs and the psychological well-being of SNS users in a two-wave longitudinal study (N=374). The results demonstrate that online authenticity had a positive longitudinal effect on three indicators of subjective well-being. The data further illustrate that this beneficial effect of SNS use is not equally accessible to all users: participants with low levels of well-being were less likely to feel authentic …
Social Influence Maximization in Hypergraphs
2021
This work deals with a generalization of the minimum Target Set Selection (TSS) problem, a key algorithmic question in information diffusion research due to its potential commercial value. Firstly proposed by Kempe et al., the TSS problem is based on a linear threshold diffusion model defined on an input graph with node thresholds, quantifying the hardness to influence each node. The goal is to find the smaller set of items that can influence the whole network according to the diffusion model defined. This study generalizes the TSS problem on networks characterized by many-to-many relationships modeled via hypergraphs. Specifically, we introduce a linear threshold diffusion process on such …
Fuzzy Concepts in Small Worlds and the Identification of Leaders in Social Networks
2014
In the study of the Social Networks, the Small World phenomenon appears frequently. We apply some techniques of graph theory and fuzzy sets to characterize the Small World features as well as the existence of the figure of leader in Social Networks. These techniques help to the conceptual formalization in relational networks analysis, by transforming linguistic and human-focused manner concepts related to social networks in some formal representation. These techniques are also applied when the similarity among nodes wants to be measured in order to study the current homophily present in a Network.
The Phenomenon of Social Enterprise in Austria: A Triangulated Descriptive Study
2011
Abstract There is little to no existing research on the phenomenon of social enterprises (SEs) in Austria. To enable subsequent comparative studies, the author first traces social enterprises' conceptual underpinnings from most current research found in leading journals and subsequently creates a framework based upon social origins theory for use on Austria's social enterprises. In order to validate the findings, the author employs a triangulated research approach, including an online-based survey, semi-structured interviews and two panel discussions. Social enterprises in Austria are characterized through social activities, organizational types, legal forms, the society sector, the outcome…
Social support for collaboration and group awareness in life science research teams
2019
Background Next-generation sequencing (NGS) technologies have revolutionarily reshaped the landscape of ’-omics’ research areas. They produce a plethora of information requiring specific knowledge in sample preparation, analysis and characterization. Additionally, expertise and competencies are required when using bioinformatics tools and methods for efficient analysis, interpretation, and visualization of data. These skills are rarely covered in a single laboratory. More often the samples are isolated and purified in a first laboratory, sequencing is performed by a private company or a specialized lab, while the produced data are analyzed by a third group of researchers. In this scenario, …
