A unified radio control architecture for prototyping adaptive wireless protocols
2016
Experimental optimization of wireless protocols and validation of novel solutions is often problematic, due to limited configuration space present in commercial wireless interfaces as well as complexity of monolithic driver implementation on SDR-based experimentation platforms. To overcome these limitations a novel software architecture is proposed, called WiSHFUL, devised to allow: i) maximal exploitation of radio functionalities available in current radio chips, and ii) clean separation between the logic for optimizing the radio protocols (i.e. radio control) and the definition of these protocols.
The image of the candidates in the 2019 General Elections in Spain
2019
[Resumen] Las Elecciones Generales de 1977 en España obligaron a los partidos a explicar cuestiones elementales como “qué significaba votar”. En general, la imagen proyectada de los candidatos era una cuestión “menor”, dada la falta de cultura democrática del momento. Tras 42 años desde la transición, el contexto político y comunicativo ha dado un vuelco que exige de una aproximación más compleja. Los partidos políticos son conscientes de la importancia que tiene construir la imagen pública de sus candidatos. En este trabajo analizamos la imagen del principal cartel de campaña de los candidatos a presidente en las Elecciones Generales de abril de 2019 de Vox, PP, C’s, PSOE, UP y del candida…

Debating Europe: Effects of the “Eurovision Debate” on EU Attitudes of Young German Voters and the Moderating Role Played by Political Involvement
2016
In the run-up to the elections to the European Parliament in 2014, EU citizens had the unprecedented opportunity to watch televised debates between the candidates running for president of the European Commission. The most important debate was the so-called "Eurovision debate", which was broadcasted in almost all EU member states. In this study we explore the responses of a sample of 110 young German voters, who watched this debate, to the candidates' messages and whether exposure to the debate caused a shift in the respondents' attitudes towards the EU. Combining data from a quasi-experiment, real-time response data, and data from a content analysis of the debate, we find that respondents' …
The relationship between online vigilance and affective well-being in everyday life: Combining smartphone logging with experience sampling
2021
Contains fulltext : 220301.pdf (Publisher’s version ) (Open Access) Through communication technology, users find themselves constantly connected to others to such an extent that they routinely develop a mindset of connectedness. This mindset has been defined as online vigilance. Although there is a large body of research on media use and well-being, the question of how online vigilance impacts well-being remains unanswered. In this preregistered study, we combine experience sampling and smartphone logging to address the relation of online vigilance and affective well-being in everyday life. Seventy-five Android users answered eight daily surveys over five days (N = 1615) whilst having their…
The risk of sexual-erotic online behavior in adolescents – Which personality factors predict sexting and grooming victimization?
2021
Abstract Information and communication technologies provide new opportunities for adolescents to establish and maintain intimate relationships, as well as exploring their sexuality. However, the young population is particularly vulnerable to becoming victims of violence or online abuse. The aim of this study was to understand to which extent the personality factors (extraversion, narcissism, lack of empathy and disinhibition) are related to sexting and online grooming victimization. The participants were 1763 adolescents between 12 and 16 years (M = 14.56, SD = 1.16, 50.99% girls). A cross-sectional design with self-report data was used, analyzed by structural equation modeling (SEM). The r…
Empirically-derived subgroups of Facebook users and their association with personality characteristics: a Latent Class Analysis
2018
Abstract In recent years, considerable research effort has been directed at the identification of relationships between psychological variables and Facebook usage indicators. However, the identification of homogeneous subgroups of individuals based on similar Facebook usage characteristics still presents a challenge. This study aims: (1) to empirically determine homogeneous groups of Facebook users based on variables regarding their personal experience on Facebook, by using a Latent Class Analysis; and (2) to examine the association between an individual's personality and interpersonal characteristics and the empirically-derived profiles of Facebook usage. Eight hundred and eleven Facebook …

Chances and Challenges of Computational Data Gathering and Analysis
2015
Digital and social media and large available data-sets generate various new possibilities and challenges for conducting research focused on perpetually developing online news ecosystems. This paper presents a novel computational technique for gathering and processing large quantities of data from Facebook. We demonstrate how to use this technique for detecting and analysing issue-attention cycles and news flows in Facebook groups and pages. Although the paper concentrates on a Finnish Facebook group as a case study, the demonstrated method can be used for gathering and analysing large sets of data from various social network sites and national contexts. The paper also discusses Facebook pla…
