Although security has become a common framework for analyzing dispositifs that aim to control irregular migration, island spaces themselves are seldom considered as security dispositifs. The case of Malta, where detention is mandatory upon arrival, epitomizes what could be conceptualized as a “sentinel island” within the European Union. This article demonstrates how the interaction between political discourse, administrative practices, and migrants’ experiences contributes to turning the island into a form of total-institution setting. The empirical data is based on qualitative fieldwork that combines ethnographic observation, migrants’ individual narratives and semi-structured interviews conducted with European and national policy makers. 相似文献

AbstractThis article evaluates the effect of armed conflict on years of schooling in Côte d’Ivoire. We combine differences in conflict intensity across departments and differences across age cohorts to identify an individual’s indirect exposure to conflict. The difference-in-difference outcomes indicate that the average years of education for a school-going-age cohort is 0.94 years fewer compared to an older cohort in conflict-affected regions. We further use a set of victimisation indicators to identify the direct effect of conflict. Overall, the findings across different models suggest a drop in average years of education by a range of 0.2 to 0.9 fewer years. The estimated effect is larger for males and individuals between 19 and 22 years of age. 相似文献

Peer victimization is a common problem among adolescents that has been linked to a variety of adjustment problems. Youth involved in peer victimization represent a heterogeneous group who may differ not only in their levels of victimization and perpetration, but also in the factors that influence their behavior. The current study used latent class analysis (LCA) to identify subgroups of aggressive and victimized youth, and to examine social-cognitive and environmental factors that differ across these subgroups. Participants were a predominantly African-American (i.e., 68 %) sample of 502 sixth, seventh, and eighth graders (45 % male, Mean age = 12.6 years) attending three urban public middle schools, who completed self-report measures of aggression, victimization, and associated individual and contextual factors. LCA identified four classes of adolescents representing non-victimized aggressors, aggressive-victims, predominantly victimized youth, and well-adjusted youth. Class differences were found on measures of beliefs supporting fighting, beliefs against fighting, perceived effectiveness of inept nonviolent responses to conflict, behavioral intentions to engage in aggressive and nonviolent behavior, self-efficacy for nonviolent behavior, and peer and parental support for aggression and nonviolence. For example, within the two classes of victimized youth, aggressive-victims reported greater intentions to engage in physical aggression and inept nonviolent behavior, and were more likely to agree with beliefs supporting the use of instrumental and reactive aggression, and beliefs that fighting is sometimes necessary compared to predominantly victimized youth. These findings emphasize the importance of developing preventive interventions that target the specific needs of distinct subgroups of adolescents. 相似文献

Studies of stress consistently have linked individuals’ experiences of stress to maladjustment, but limited attention has been given to cultural stressors commonly experienced by minority individuals. To address this, the current study examined the links between cultural stressors and prospective changes in mental health symptoms in a sample of 710 (49 % female) Mexican American youth. In addition, the moderating role of both family and neighborhood cohesion was examined. In-home interviews were completed with youth, mothers (required) and fathers (optional) to collect data on youth’s experiences of cultural stressors (discrimination and language hassles) and internalizing/externalizing behavior, and mothers’ report of family cohesion and mothers’ and fathers’ report of neighborhood cohesion. Analyses revealed that youth’s experiences of discrimination and language hassles at 5th grade were related positively to increases in internalizing symptoms at 7th grade. Additionally, youths who reported higher levels of language hassles in 5th grade experienced increases in externalizing symptoms across the 2-year span. Both family and neighborhood cohesion emerged as significant moderating factors but their impact was conditional on youth’s gender and nativity. Limitations and future implications are discussed. 相似文献

Generativity, defined as concern for future generations, is theorized to become a priority in midlife, preceded by a stage in which intimacy is the central issue. Recent research, however, has found evidence of generativity even in adolescence. This longitudinal study explored the associations between caregiving in friendships, closely related to intimacy, and early generative concern in a young adolescent sample. Given the importance of close friendships in adolescence, it was hypothesized that responsive caregiving in early adolescent friendships would predict later generative concern. Approximately 140 adolescents (56 % female, aged 14 at Time 1) completed questionnaires regarding generative concern and responsive caregiving with friends yearly across 2 years. Structural equation modeling revealed that caregiving predicted generative concern 1 year later but generative concern did not predict later caregiving. These results suggest that caregiving in close friendships plays an important role in the development of adolescents’ motivation to contribute to future generations. 相似文献

When people talk about their lives, people lie sometimes, forget a little, exaggerate, become confused, and get things wrong. Yet they are revealing truths … the guiding principle for [life histories] could be that all autobiographical memory is true: it is up to the interpreter to discover in which sense, where, and for what purpose.
