Psychological empowerment encompasses several key aspects of youth civic and sociopolitical development. Most research has focused on psychological empowerment’s emotional component, which entails learned hopefulness about one’s own ability to participate in and lead community change efforts. Fewer studies have assessed critical awareness of how social power operates—psychological empowerment’s cognitive component. The confluence of these two components has been termed critical hopefulness. A complex relationship exists between these two components, and previous research has found relatively small proportions of participants reporting both high levels of critical awareness and simultaneously high levels of hopefulness about their ability to exert influence in the sociopolitical domain. The current study of urban high school students in the Northeastern U.S. (n?=?389; 53.5% female) investigates heterogeneity according to these two components of psychological empowerment. Latent class cluster analyses were conducted and seven distinct groups of participants emerged. Students identifying as Hispanic/Latinx were more likely to be classified into a profile group exhibiting critical hopefulness. Differences were observed between psychological empowerment profile groups on self-reported levels of psychological sense of community, civic engagement, and social justice orientation. Furthermore, a larger proportion of this overall sample was classified into groups that exhibited critical hopefulness than in a previous study of adults. These findings provide useful insights for efforts to engage young people in civic life and to promote sociopolitical development.  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

Despite the large contingent of students living in rural areas, existing research on the processes that precede the college enrollment of rural adolescents is limited. With a particular focus on gender, this study investigated rural adolescents’ perceptions of family and place and how these perceptions related to their educational aspirations and subsequent college enrollment using a nationwide sample of rural adolescents (N?=?3456; 52.5% female). Female adolescents reported higher academic achievement, educational aspirations, parental expectations, and family responsibility and enrolled in two-year and four-year institutions at greater rates compared to male adolescents, who reported significantly higher rural identity and perceptions of job opportunities in the rural community. Utilizing a multiple group moderated mediation approach, the results provided evidence that adolescents’ increased perceptions of their parents’ educational expectations were associated with increased educational aspirations and college enrollment and that adolescents’ increased perceptions of job opportunities in their rural community were associated with decreased educational aspirations. In addition, the results showed that gender moderated the relation between perceptions of job opportunities in the rural community and postsecondary enrollment. These findings highlight how the developmental resources of family and place relate to adolescents’ educational aspirations and subsequent postsecondary enrollment.  相似文献

This paper appraises the role of critical-feminist figurations within the environmental humanities, focusing on the capacity of figures to produce situated environmental knowledges and pose site-specific ethical obligations. We turn to four environments—the home, the skies, the seas and the microscopic—to examine the work that various figures do in these contexts. We elucidate how diverse figures—ranging from companion animals to birds, undersea creatures and bugs—reflect productive traffic between longstanding concerns in feminist theory and the environmental humanities, and generate new insights related to situated knowledges, feminist care-ethics and the politics of everyday sensory encounters. We also argue, however, that certain figures have tested the limits of theoretical approaches which have emerged as the product of dialogue between feminist theory and environmental studies. In particular, we explore how particular figures have complicated ethical questions of how to intervene in broad environmental threats borne of anthropogenic activities, and of who or what to include in relational ethical frameworks.  相似文献

We set out by noting the preference for circular flows in ecological thought, and the related abhorrence of inefficiency and waste that Western ecology shares with mainstream economic thinking. This has often been manifest in a shared disdain both for uncontained, free-burning fire and for ‘unmanaged’ sexual desire. The paper constructs a ‘pyrosexual’ counter-narrative that explores the mutually constitutive and generative implication of sex and fire. Bringing together the solar ecology of Georges Bataille, feminist and queer thinking about sexuality and reproduction, and a range of ways of theorising biological life and fire, we explore how fire mediates between organismic desire and the energetic dynamics of the earth and solar system. The first section takes a genealogical approach to fire and sex that traces their entanglement from the initial ‘assembling’ of fire through to the emergence of a fire-handling creature. The second section looks at how fire has been contained and intensified by human actors, and the role that heat-driven transformations of inorganic matter have played in the incitement and channeling of desire in urban spaces. The third section addresses the development of industrial ‘heat engines’ and the implications for desire and reproduction of tapping vast reservoirs of subterranean solar energy. We round off by beginning to consider what alternative possibilities might lie in the renegotiation of sex and fire on a planet undergoing rapid change.  相似文献

A new political moment is underway. Although there are significant differences in how this is constituted in different places, one manifestation of the new moment is the rise of distinct forms of authoritarian populism. In this opening paper of the JPS Forum series on ‘Authoritarian Populism and the Rural World’, we explore the relationship between these new forms of politics and rural areas around the world. We ask how rural transformations have contributed to deepening regressive national politics, and how rural areas shape and are shaped by these politics. We propose a global agenda for research, debate and action, which we call the Emancipatory Rural Politics Initiative (ERPI, www.iss.nl/erpi). This centres on understanding the contemporary conjuncture, working to confront authoritarian populism through the analysis of and support for alternatives.  相似文献

The isolation of spermatozoa from sexual assault swabs using proteinase K   总被引:1,自引:0,他引:1  
The most common examination in sexual offences is the identification of spermatozoa in aqueous extracts from swabs. Using Proteinase K with sodium dodecyl sulphate, it is possible to digest all the cellular material apart from the spermatozoa, resulting in a quick and effective method of their isolation. Spermatozoa were detected in 18 extracts using this treatment when the normal method had failed to reveal all but one of them.  相似文献

A simple but rigorous approach is offered for evaluating the evidential value of single locus DNA autoradiographs. This approach does not use a binning technique and it does not treat alleles as discrete variables. Instead, the allele distribution is considered to be continuous. The variation between two comparable bands is assessed using previously determined experimental parameters. The Bayesian treatment leads to an expression of the "quality of a match".  相似文献
