Perceived emotional intelligence and social competence in neglected adolescents

This research work analyses the emotional intelligence (EI) and the social cognitive attitudes and strategies in adolescents between 12 and 17 years of age in residential care. The aim of the work is to identify those aspects that hinder their socio-emotional competence, requiring a more urgent intervention. We explore the presence of significant differences between the variables under study according to gender and age range (12–14 and 15–17) and we analyse the relationship between the dimensions of their EI and their social competence. The results show a lack of EI in these adolescents, with all three dimensions being affected: emotional attention, clarity of feelings and emotional repair. As for social competence, it can be seen that the adolescents are characterised by a lack of confidence and firmness in their interactions. Worthy of note is the impulsive cognitive style, as are the rigidity of thought and the tendency towards social mistrust and suspicion. There are many difficulties concerning the strategies for resolving social problems. This research highlights the need to design training programmes for the residential care centres that will favour their socio-emotional development.     

Building Universal Socio-cultural Indicators for Standardizing the Safeguarding of Citizens’ Rights in Smart Cities

This research explores the opportunity to use standards as recommender instruments for designing urban policy. Standards are soft regulatory mechanisms that can be used for monitoring and safeguarding. More precisely, we explore the potential use of social standards for centering the focus of the smart cities initiative back to the citizens, and establishing a citizen-centered approach. This is in contrast to the industrial drive and technological emphasis which currently dominates. Accordingly, we present a set of novel citizenship indicators which serve as the basis for the social standardization of smart cities, something which is not now taking place, in order to ensure and safeguard the basic social urban rights of citizens. The juridical basis and well-established points of reference for building indicators for citizens’ rights in the city are two International Charters. These are the European Charter for the Safeguarding of Human Rights in the City, and the Global Charter-Agenda for Human Rights in the City. In this paper, we start by comparing and analyzing the rights contained in each of the two Charters, and elaborating indicators for measuring the promotion and protection of these rights. The elaboration of indicators has been based on different criteria and under the common premise of universal existence of feeding data, which is the most recurrent problem when building indicators meant to be global. Next, at the request of the International Standards Organization (ISO), we select the most relevant socio-cultural indicators for the Global Charter Agenda, which will be introduced in the on-going revision of the smart cities and communities standard ISO 37120:2014 Sustainable development of communities—Indicators for city services and quality of life. This will make ISO 37120 a more beneficial social standard for monitoring and safeguarding citizens’ rights in the smart city.     

Portuguese Scientists’ Migration: a study on the 2008 crisis aftermath

In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision.     

Multi‐sited accumulation of capital: Cape Verdean returnees and small‐scale business

In recent years, policymakers have portrayed return migration as positive for development. In both migrant sending and migrant receiving countries, policymakers expect the transfer of economic, cultural and social capital by returnees to stimulate economic growth. Inherent in these assumptions is the idea of a unidirectional flow of capital from northern countries of immigration to the countries of return. The objective of this article is to contest this idea of a one‐way transfer of capital through a case study of Cape Verdean returnee business owners. To what extent have they accumulated their various forms of capital before emigration, during their sojourn abroad or after return? In this article, I examine the returnees' multi‐sited accumulation of capital and how it corresponds to the resources they need to run a sustainable business. In addition, I analyse how they adapt capital accumulated abroad to the conditions in Cape Verde.     

Social workers' assessments of needs and interventions for adolescents with substance misuse problems,criminal behaviour and mental health difficulties: a vignette study

The aim of the current vignette study was to examine how social workers assess adolescents with substance misuse problems, criminal behaviour and mental health difficulties, and how they make decisions about treatment interventions to reduce these problems. Earlier research has shown lack of knowledge concerning factors and processes that govern assessments and decisions in social work practice. In this anonymously administered survey, social workers in Stockholm, Sweden, were invited to assess fictitious youth issues. We found that social workers recognise the problems and needs of young people, but that they find it harder to link needs to evidence-based interventions. Also, there is a tendency to overrate alleged non-serious problems in the vignettes. We conclude that there is a need for increased knowledge about evidence-based methods and more structured procedures to broaden the basis for decisions.     

Looking for max-semistability: A new test for the extreme value condition

To test the extreme value condition, Cramér-Von Mises type tests were recently proposed by Drees et al. (2006) and Dietrich et al. (2002). Hüsler and Li (2006) presented a simulation study on the behavior of these tests and verified that they are not robust for models in the domain of attraction of a max-semistable distribution function. In this work we develop a test statistic that distinguishes quite well distribution functions which belong to a max-stable domain of attraction from those in a max-semistable one. The limit law is deduced and the results from a numerical simulation study are presented.
