The Phenomenology of Specialization of Criminal Suspects
2012
A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish suspects to empirically investigate generalist and specialist behavior in crime. We show that there is a large group of suspects who can be described as generalists. At the same time, we observe a non-trivial pattern of specialization across age and gender of suspects. Women are less prone to commi…

Living alone vs. living with someone as a predictor of mortality after a bone fracture in older age
2020
Abstract Background Living alone is a risk factor for health decline in old age, especially when facing adverse events increasing vulnerability. Aim We examined whether living alone is associated with higher post-fracture mortality risk. Methods Participants were 190 men and 409 women aged 75 or 80 years at baseline. Subsequent fracture incidence and mortality were followed up for 15 years. Extended Cox regression analysis was used to compare the associations between living arrangements and mortality risk during the first post-fracture year and during the non-fracture time. All participants contributed to the non-fracture state until a fracture occurred or until death/end of follow-up if th…
CONSTRUCTION OF THE SOCIAL IMAGINARY OF ALTERNATIVE THERAPIES THROUGH DISCOURSE IN SOCIAL NETWORKS: CASE STUDY OF THE CHANNEL "ALTERNATIVE THERAPIES …
2019
Resumen: El objetivo de esta investigación es analizar cómo se construye el imaginario social de las terapias naturales, complementarias y alternativas a través de su discurso en redes sociales. Para ello, se ha escogido el canal temático “Terapias alternativas y remedios naturales” de la plataforma YouTube. Se ha realizado un análisis de contenido de dicho canal y se han examinado las sinergias con la página de Facebook, y el sitio web que se vinculan al mismo, con la finalidad de determinar si, además de contribuir en la difusión de estas terapias, existe una intencionalidad distinta. El periodo de análisis del canal temático ha sido de un año: desde julio de 2017 a julio de 2018. Se ha s…
Seed Activation Scheduling for Influence Maximization in Social Networks
2018
This paper addresses the challenge of strategically maximizing the influence spread in a social network, by exploiting cascade propagators termed “seeds”. It introduces the Seed Activation Scheduling Problem (SASP) that chooses the timing of seed activation under a given budget, over a given time horizon, in the presence/absence of competition. The SASP is framed as a blogger-centric marketing problem on a two-level network, where the decisions are made to buy sponsored posts from prominent bloggers at calculated points in time. A Bayesian evidence diffusion model – the Partial Parallel Cascade (PPC) model – allows the network nodes to be partially activated, proportional to their accumulat…
Social networks : promoting Mexican popular cultures and building a participatory culture
2012
For over 30 years, the General Direction of Popular Cultures has been in charge of promoting, preserving, and disseminating the cultural diversity of Mexico, regarding indigenous and popular cultural practices. With the increasing popularization of Social Networks, it has become almost indispensable to join Social Networks in order to exist digitally, weather you are an individual, an institution or government. Taking this fact in consideration, in 2011 the Direction of Popular Cultures joined the most utilized social Networks in México: Twitter, Facebook and YouTube, as a way to keep users updated about the activities and general information generated by the Direction. Departing form the p…

Anàlisi feminista de les xarxes socials de les migrants colombianes al País Valencià
2010
The results of this piece of research2 on migrant women3 are presented from a feminist approach. The research shows the current diversity in migration processes and, specifically, the key role of finding out the social practices of political migrants. The differences and similarities found in the two groups' social networks and practices are identified and compared from a social point of view, through a completely new interpretation of the concepts of economic and political migrants. This research thus aims to understand the characteristics of participative practices within the group of Colombian migrants living and taking part in two societies at the same time.
Revealing Employer’s Name in Social Networks
2017
Abstract The research investigates the question of the importance of mentioning the name of the employer in online and offline social networks. The exchange of information is an important part of social networks and social capital theory. Companies can use the networks of their employees to recruit new hires and to check habits and interests of likely new employees. To do that, the employee has to mention the name of the company in these social networks. The paper compares different real social networks used by family and friends and private and business social network sites (SNSs) as online social networks and compares the differences between men and women. The empirical research has been …
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…
