Now in its sixth year, the war in Syria has triggered the largest humanitarian and refugee crisis of our time. For most refugees and migrants, Turkey is the main transit country to reach Europe, where Syrian refugees hope for a better future. However, this journey has been hampered as several European countries closed their borders following the arrival of an unprecedented number of migrants and asylum seekers in 2015. In response, a deal was struck with Turkey to stem the migrant flow to Europe in exchange for some concessions. By outsourcing the management of migration flows to Turkey, the EU is failing to take its fair share of responsibility for refugee protection. Furthermore, as a result of the political situation in Turkey and the unmet promises under the deal, relations between Turkey and the EU have touched their lowest point since the start of accession negotiations in 2005. While survival of the deal is of critical importance as the EU needs Turkey’s assistance in curbing migration flows and Turkey is keen on revitalising its accession negotiations, the deal has exposed serious flaws that need to be addressed and must not be replicated with other countries.  相似文献

Developmental imbalance models attribute the rise in risk-taking during adolescence to a universal imbalance between rising reward sensitivity and lagging cognitive control. This study tested predictions of an alternate Lifespan Wisdom Model that distinguishes between exploratory/adaptive (e.g., sensation seeking) and maladaptive (e.g., acting-without-thinking, delay discounting) risk-taking propensities and attributes the latter to a sub-set of youth with weak cognitive control. Latent trajectory modeling of six waves of data from 387 adolescents (52% females; spanning average ages of 11–18 years) revealed distinct sub-groups with heterogeneous trajectory patterns for acting-without-thinking and delay-discounting. Only those trajectory groups with weak cognitive control, characterized as “high-increasing” acting-without thinking and “high-stable” delay discounting were predictive of a maladaptive risk-taking outcome, namely substance use disorder. Sensation seeking demonstrated a universal peak, but high levels of sensation seeking were not associated with weakness in cognitive control and were unrelated to substance use disorder, controlling for impulsivity. The findings suggest that maladaptive risk-taking characterized by weak cognitive control over reward-driven impulses is a phenomenon limited to only a sub-set of youth.  相似文献

Although media exposure has been related to cognitive preoccupation with appearance, research rarely investigated adolescents’ behavioral self-sexualization. To address this gap, the present study among 12- to 16-year-olds (N?=?1527; 50.2% girls) in Austria, Belgium, Spain, and South-Korea (1) investigates whether different types of media use relate to self-sexualization, (2) explores the explanatory value of rewarded appearance ideals, and (3) considers culture and gender as moderating factors. Despite cultural variation, a general trend of increasing self-sexualization with social media use and magazine reading appeared across the countries. Moreover, women’s magazine reading and rewards were related to self-sexualization among all the girls across the countries, which suggests that girls may be more vulnerable to the examined effects. Overall, this study provides a better understanding of the unique contribution of specific media genres to youth’s self-sexualization and points at the importance of social media use in girls’ and boys’ engagement in sexualizing appearance behaviors across four countries.  相似文献

The goal of the current study was to examine the protective role that maternal media monitoring might have for adolescents. This was done by considering whether styles of media monitoring either directly reduced media use, or whether they buffered the associations between aggressive media use and adolescents’ prosocial behavior, aggression, and delinquency. Participants were 681 adolescents from two cities in the United States (51% female; 73% white), and their mothers, who provided data at two different time points, 2 years apart (when adolescents were roughly ages 13 and 15). Mixture modeling results revealed that mothers used four different styles of media monitoring made up of combinations of active and restrictive monitoring as well as forms of co-use. Styles that included active monitoring and connective co-use (i.e., engaging in media with the intent to connect with children) were directly associated with less media use, and moderated links between adolescents’ media use and behavioral outcomes concurrently but not longitudinally. The discussion was focused on the strength of considering multiple strategies of media monitoring together, and how this approach can inform future research in the area of parental media monitoring.  相似文献

Employee turnover—due to retirement, moving from one work unit to another, or leaving an organization entirely—imposes considerable costs on organizations. While private organizations make use of several high-powered incentives to retain workers, public organizations typically lack comparable incentives. Fortunately, public employees frequently possess stronger intrinsic motives to stay. Our results indicate that employee voice is an especially useful tool in the U.S. federal government. Evidence is also consistent with a substantial “contagion” effect: when others in an agency seek to leave, individual employees in that agency are more likely to report turnover intentions than similar employees in agencies with more “stayers.”  相似文献

Educational approaches that enable students to actively and directly participate in “real-world” projects are increasingly recognized as valuable pedagogical tools and, as such, being incorporated into university curriculums worldwide. Though not traditionally associated with political science courses, project-based international service learning presents a tremendous opportunity to bring classroom concepts and theories to life, provide an active approach to addressing international challenges, and assist students in the development of the hands-on, problem-solving, team-based, critical-thinking skills that are increasingly important to employers across all sectors. This article seeks to encourage political science faculty to incorporate international service learning—and/or project-based approaches—into their educational offerings. Through examination of the course Global Synthesis in Liberal Arts and Engineering Studies at California Polytechnic State University, we have identified multiple factors that can help promote successful execution of project-based international service learning as a pedagogical tool, and provide additional suggestions for faculty interested in adopting specific aspects of these educational approaches, and/or in doing so closer to home.  相似文献

Having an adult mentor during adolescence has been found to predict academic success. Building on previous work, the present study examined interactions between the type of mentor (i.e., kin, teacher, friend, or community), the time that mentor became important (i.e., before, during, or after high school), and the ethnicity of the protégé in predicting educational attainment in young adulthood. Analyses used Waves III and IV of the National Longitudinal Study of Adolescent Health (N = 2,409). Participants’ ages ranged from 18 to 27 (M = 21.75, SD = 1.79). The sample was 56.7 % female and nationally representative of ethnic diversity. Analyses showed that having a teacher-mentor was more predictive of educational attainment than having other types of mentors and that overall, having a mentor after high school predicts the most educational attainment. Kin- and community-mentors appeared to be more important to educational attainment during and before high school, respectively. Findings were consistent across ethnic groups. Overall, results highlight the value of teacher-mentors throughout childhood, adolescence, and early adulthood and our study further suggests that different types of mentors may be particularly useful at specific points in development.  相似文献

Social cognitive models examining academic and career outcomes emphasize constructs such as attitude, interest, and self-efficacy as key factors affecting students’ pursuit of STEM (science, technology, engineering and math) courses and careers. The current research examines another under-researched component of social cognitive models: social support, and the relationship between this component and attitude and self-efficacy in math and science. A large cross-sectional design was used gathering data from 1,552 participants in four adolescent school settings from 5th grade to early college (41 % female, 80 % white). Students completed measures of perceived social support from parents, teachers and friends as well as their perceived ability and attitudes toward math and science. Fifth grade and college students reported higher levels of support from teachers and friends when compared to students at other grade levels. In addition, students who perceived greater social support for math and science from parents, teachers, and friends reported better attitudes and had higher perceptions of their abilities in math and science. Lastly, structural equation modeling revealed that social support had both a direct effect on math and science perceived abilities and an indirect effect mediated through math and science attitudes. Findings suggest that students who perceive greater social support for math and science from parents, teachers, and friends have more positive attitudes toward math and science and a higher sense of their own competence in these subjects.  相似文献

The otherwise extensive historiography of slavery in colonial America has rather neglected the overseer and his family, as indeed the wider historiography of colonial society has often neglected the white poor. By considering, specifically, the role of overseers' wives, this article seeks to recover the history of poor white women who, although often vilified by their employers for their allegedly wayward behaviour, made a significant contribution, economically and socially, to the plantation community. By so doing, it casts fresh light upon white women who lived on the margins of wider colonial society and the shadowy ‘edges’ of slavery itself.  相似文献
