The Development of Four Types of Adolescent Dating Abuse and Selected Demographic Correlates

This study determined the shape of trajectories from ages 13 to 19 of 4 types of dating abuse perpetration and examined whether the demographic characteristics of sex, minority status, socioeconomic status, and family structure systematically explained variation in the trajectories. The data are from 5 waves of data collected from 973 adolescents participating in the control group of a randomized trial. The mean trajectory for psychological dating abuse was positive linear, but the mean trajectories were curvilinear for moderate physical, severe physical, and sexual dating abuse. At all ages, boys reported more severe physical and sexual dating abuse than girls, minorities reported more moderate and severe physical dating abuse than Whites, adolescents in single‐parent households reported more psychological and severe physical dating abuse than those in 2‐parent‐households, and parental education was negatively associated with psychological and moderate physical dating abuse perpetration. The findings have implications for future research and for practice.     

Parameter Estimation for the Tail Distribution of a Random Sequence

The tail Y_t = X_t – u of a random sequence {X_t ∈ , t ∈ } with identically distributed X_t is approximated by the generalized Pareto distribution according to the extreme value theory, wherein Y_t occurs in clusters because of the dependence in the random sequence. Nevertheless, the parameters of the generalized Pareto distribution are estimated by the same methods as in the case of independent and identically distributed Y_t, provided that there is independence between the clusters of Y_t. The estimation variances and confidence intervals can be estimated by the jackknife method. The approaches are theoretically discussed and verified by extensive numerical researches.     

Influence of musical genres with Andean contents on the components of Peruvian national identity / Influencia de géneros musicales con contenidos andinos en los componentes de la identidad nacional peruana

The purpose of this study is to analyse the influence of different musical genres with Andean influences (Huayno, Chicha and Rock/Fusion) on the components of Peruvian national identity. To this end, we enlisted the participation of 92 upper-middle-class people (M = 19.91, SD = 1.95). The participants were randomly assigned each music genre in three experimental groups: Huayno (n = 30), Chicha (n = 31) and Rock/Fusion (n = 31). The results show that Rock/Fusion is the most highly rated musical genre with the most positive influence on some stereotypical components of national identity, attitude towards music and positive emotions. In contrast, the more ‘Andeanized’ genres, especially Chicha music, are perceived more negatively and have fewer positive effects on the stereotypical components of national identity, attitude towards music and positive emotions. The discussion suggests that the influence of the musical expressions evaluated depends on the ascribed status of the social group where these expressions were originally conceived and are currently consumed.     

Reasons for Leaving the Academy: a Case Study on the ‘Opt Out’ Phenomenon among Younger Female Researchers

This study provides a contemporary case for exploring the assumed ‘opt out’ phenomenon among early‐career female researchers. Based on rich data from a Danish case study, we adopt an integrated, holistic perspective on women's reasons for leaving the academy. We propose the concept of ‘adaptive decision‐making’ as a useful analytical starting point for synthesizing structure‐ and agency‐centred perspectives on academic career choices. Our study provides new insights into the myriad of structural and cultural conditions circumscribing the career ambitions and expectations of younger female (and male) researchers, at a critical transition point epitomized by high demands for scholarly productivity, international mobility and accumulation of social capital. Located within the context of Danish higher education, our study also adds to the current discussion of why academic gender stratifications persist in a country renowned for its leading international position on issues of societal gender equality.     

The age-varying effects of adolescent stress on impulsivity and sensation seeking

Adolescence is defined in part by heightened exposure and sensitivity to stressors. In a longitudinal cohort of youth at risk for substance use problems, we examined the age-varying relationship between stress exposure and traits that are central to the dual systems model. The positive associations between stress exposure, impulsivity, sensation seeking varied as function of age. Specifically, the influence of stress exposure on impulsivity strengthened during early adolescence and remained stable into early adulthood, while the influence of stress exposure on sensation seeking strengthened from early- to mid-adolescence and weakened thereafter. These findings suggest that the maturational imbalance between the capacity to regulate impulsive tendencies and sensation seeking may be exaggerated for youth who are exposed to a high number of stressors.     

Internal and International Migration Across the Urban Hierarchy in Albania

The interactions between the processes of urbanization and international migration in less developed and transition countries have important repercussions for socioeconomic development, but are not well understood. Based on the retrospective data from the Albanian Living Standards Measurement Survey 2008, we first assess the geography of migration in terms of the rural–urban continuum, the urban hierarchy and the outside world since 1990. We then investigate the spatio-temporal diffusion of rural-to-urban and international movements using survival models. Results reveal an immediate onset of large-scale rural exodus, despite the post-communist crisis. Internal migrants mainly moved to the capital, bypassing secondary cities, and were predominantly female. Initially, international migrants were primarily men who tended to originate from the main urban agglomerations. The diffusion of opportunities to emigrate down the urban hierarchy and across the sexes then redirected the rural exodus abroad, despite domestic economic development. This evolution in population mobility is related to the gendered patterns and interlinkages of the two flows, as well as to rising inequalities within the urban hierarchy.
