A Characterization for the Spherical Scoring Rule

Strictly proper scoring rules have been studied widely in statistical decision theory and recently in experimental economics because of their ability to encourage assessors to honestly provide their true subjective probabilities. In this article, we study the spherical scoring rule by analytically examining some of its properties and providing some new geometric interpretations for this rule. Moreover, we state a theorem which provides an axiomatic characterization for the spherical scoring rule. The objective of this analysis is to provide a better understanding of one of the most commonly available scoring rules, which could aid decision makers in the selection of an appropriate tool for evaluating and assessing probabilistic forecasts.      

Efficacy of a brief intervention on attitudes to reduce school violence: A randomized clinical trial

There is growing interest in the phenomenon of school violence, which has been associated in diverse works with youth's attitudes towards violence, and it has been the focus of many intervention programs. However, the high human and economic cost entailed can impede its administration in some school centers. Therefore, the goal of the present study is to assess the efficacy of a brief intervention aimed at modifying attitudes towards violence to reduce the phenomenon of school bullying. The sample was obtained from a Secondary Education Institute during the 2010–2011 school term, and was made up of 252 students aged between 12 and 15 years. A controlled and randomized design was used in order to assess the effects of the program “Count on Me.” Ten classrooms were randomly assigned either to the intervention or to a waiting-list. Results show a significant reduction of playground violence perceived by the students, especially among the girls. Implications for the development of future brief programs for the prevention of school violence are discussed.     

Multidimensional Poverty in Paraguay: Trends from 2000 to 2015

The paper discusses Kenneth C. Land and Alex C. Michalos’ review and assessment of the evolution of research on social indicators, quality of life and well-being over the past fifty years. The contribution deals with the impacts of three major societal changes on the future research agenda of social indicators research: firstly, impacts of the changing class structure of post-industrial society, secondly, globalization impacts, including its economic, political, cultural and institutional dimensions, and thirdly, the impacts of an increasingly networked digitalization of production and consumption.     

Does Premarital Cohabitation Predict Subsequent Marital Stability and Marital Quality? A Meta‐Analysis

Cohabitation with a romantic partner has become common in recent decades. This meta‐analysis examined the link between premarital cohabitation and marital stability ( k = 16) and marital quality ( k = 12). Cohabitation had a significant negative association with both marital stability and marital quality. The negative predictive effect on marital stability, however, did not remain when only cohabitation with the eventual marital partner was analyzed, suggesting that these cohabitors may attach more long‐term meaning to living together. Moderator analyses demonstrated that effects of cohabitation have remained consistent over time, despite the fact that cohabitation has become more normative.     

Identity,language, and ethnic relations in the Bilingual Autonomous Communities of Spain1

This study surveyed 2446 undergraduates from five Bilingual Autonomous Communities (BAC) of Spain. We propose that the creation of the BAC of Spain in 1978 allowed the development of differing prototypic identities ranging from Spanish only identity, Autonomous only identity, and various permutations of dual Spanish/Autonomous identities. Based on their linguistic and ethnic self‐identifications, the percentage of participants endorsing each prototypic identity was monitored along with their key sociopsychological correlates. Six prototypic identity profiles were obtained. Results indicate that individuals endorsing the Autonomous only (11%) and Spanish only (13%) identities were more likely to engage in problematic intergroup relations. Strong Dual identifiers (9%) are the most likely to act as cultural and linguistic brokers and to foster intergroup harmony. Pro‐Spanish (15%) and Moderate Dual (7%) identifiers are more likely to benefit from language learning in the Autonomous language and emerge as cultural brokers. Esta investigación sondeó 2446 estudiantes de pregrado de cinco Comunidades Autónomas Bilingües (CAB) de España. Proponemos que la creación de las CAB de España en 1978 permitió el desarrollo de diferentes identidades prototípicas que van desde identidades solamente españolas, identidades solamente autónomas hasta varias permutaciones de identidades dobles españolas/autónomas. Basado en sus auto‐identificaciones lingüística y étnica, se observó el porcentaje de participantes que corresponden a cada identidad prototípica y sus correlacionados socio‐psicológicos claves. Se obtuvieron seis perfiles de identidad prototípicos. Los resultados indican que los individuos que asumen una identidad solamente autónoma (11%) y solamente española (13%) tienen más probabilidades de entablar relaciones intergrupales problemáticas. Los que tienen más probabilidades de comportarse como conciliador cultural y lingüístico, y de fomentar armonía intergrupal son los que asumen una fuerte identidad doble (9%). Los que asumen una identidad pro‐española (15%) o una identidad doble moderada (7%) tienen más probabilidades de beneficiar del aprendizaje de la lengua autónoma y se revelaron como conciliador cultural.     

The Joint Development of Traditional Bullying and Victimization With Cyber Bullying and Victimization in Adolescence

The present study investigated the stabilities of and interrelationships among traditional (i.e., face‐to‐face) bullying, traditional victimhood, cyber bullying, and cyber victimhood among adolescents over time. About 1,700 adolescents aged 11–16 years at Time 1 self‐reported levels of both bullying and victimization in four contexts (in school, outside of school, texting, and on‐line) annually for 2 years. Results indicated that all four dynamics were moderately stable over time. The following variables were found to bidirectionally reinforce and predict each other over time: traditional bullying and traditional victimization; traditional bullying and cyber bullying; and traditional victimization and cyber victimization. These results indicate that bullying and victimhood in both face‐to‐face and cyber‐based interactions are related but not identical interpersonal dynamics.     

Organizational Wellbeing in CSOs in Morelos (Mexico): Findings from a Qualitative Study

In recent years, civil society organizations (CSOs) have become a significant aspect of Mexican reality given the number of people involved in them and their contribution to the services sector. These entities are organizations where voluntary and paid workers may experience wellbeing conditions that are inherent in empowerment processes, feelings of usefulness, and the satisfaction associated with participating in decision-making. At the same time, contradictory dynamics related to governance, power relations, leadership, and decision-making may be activated in CSOs and create uncertainty and psychosocial malaise. In this research, based on a grounded theory approach, 11 interviews and 89 questionnaires were realized in 14 service-providing CSOs in the Mexican State of Morelos, highlighting the wellbeing/malaise dimensions and psychosocial factors that are relevant for their members.
