In light of its associations with child and adolescent health and well-being, there remains a need to better understand the etiological underpinnings and developmental course of internalizing symptomatology in children and adolescents. This study leveraged intensive longitudinal data (N?=?959; 49.6?% females) to test the hypothesis that internalizing symptoms in childhood may be driven more strongly by family experiences whereas internalizing symptoms in adolescence may derive more uniquely from familial loading for affective disorders (i.e., maternal depression). We evaluated the relative contributions of (a) family experiences (b) maternal depression, and (c) peer influences in testing this hypothesis. The results indicated that family predictors were more strongly correlated with childhood (relative to adolescent) internalizing symptoms. In contrast to previous findings, maternal depression also exhibited stronger associations with childhood internalizing symptoms. Although often overlooked in theories concerning potential differential origins of childhood vs. adolescent internalizing symptomatology, peer experiences explained unique variation in both childhood and adolescent internalizing problems.  相似文献

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.  相似文献

Agentic orientations developed in adolescence have been linked to better health, well-being, and achievements in the years following. This study examines longitudinal parental influences on the development of adolescent children’s agentic orientations, captured by the core constructs of mastery beliefs and generalized life expectations. Drawing on multigenerational panel data from the United States (1991–2011), the study examines contemporaneous family factors, but also how parental biographies (their own transition to adulthood) and parents’ own adolescent agentic orientations influence their adolescent children. Study adolescents were 46% male, 52% white, and 15.6 years old on average. The findings indicate that parents’ early orientations and experiences in the transition to adulthood have little effect on their children’s mastery beliefs, but that parents’ generalized life expectations (in adolescence) and having married before having the child were associated with their children’s more optimistic life expectations. Contemporaneous family income and optimistic expectations among parents-as-adolescents were somewhat substitutable as positive influences on adolescents’ optimistic life expectations. The findings contribute to our understanding of intergenerational and over-time influences on these key adolescent orientations.  相似文献

Abstract

We contribute to the debate on the spatial allocation of infrastructure investments by examining where these investments generate the highest economic return (‘spatial efficiency’), and identifying trade-offs when infrastructure coverage is made more equitable across regions (‘spatial equity’). We estimate models of firm location choice in Uganda, drawing on insights from the new economic geography literature. The main findings show that manufacturing firms gain from being in areas that offer a diverse mix of economic activities. Public infrastructure investments in other locations are likely to attract fewer private investors, and will pose a spatial efficiency–equity trade-off.  相似文献

Moral convention required that the eighteenth‐century English novelist express disapproval of the opportunities London afforded women for mobility, deception, and independence. Women novelists of the period, however, subverted this code by depicting urbanized heroines who gain forbidden knowledge about male and female sexuality and social roles, and are thus able to manipulate convention rather than merely following it. Examination of five novels of the period — two by men, three by women — demonstrates that male and female novelists, while allegedly working within the same moral framework, generated vastly different moral texts out of the complex semiotic of the London environment. As the novel gained in respectability, women novelists’ use of the London convention became on the surface more conventional, and their heroines’ attitudes toward urban mores more disapproving, but subversive alternative behaviors are still depicted in late eighteenth‐century novels.  相似文献

Abstract This article analyses how politicians' use of emotion is gendered. Key Australian, US and UK politicians studied include Obama, George W. Bush, Hillary Clinton, Cameron, Rudd, Abbott and Gillard. Emotions analysed range from fear to compassion. A particular focus is placed on issues of masculinity; however, the implications for constructions of both femininity and masculinity will be considered, including arguments that female politicians face particular problems in utilising emotion, for example, in projecting an image of being both tough and compassionate. It will be argued that it is not just that politicians' use of emotion intersects with issues of gender but that particular gendered identities are a key vehicle via which emotion is deployed. Consequently, the analysis contributes new insights to both the literature on the politics of emotion and the literature on masculinity and gender.  相似文献

Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying—as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement—and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.  相似文献

Drawing on comparisons with cooperative and competitive non-state health care provision around the world, this article analyses non-state provision of health services in post-Soviet Uzbekistan and Kazakhstan. It explores the conditions in which non-state provisions remain cooperative or become politicised and contrasts the relations between NGOs and the state in Uzbekistan and Kazakhstan and the way they became politicised in the Middle East. In contrast to Western conceptions of NGOs, Central Asia's health NGOs cooperate with state agencies to serve their constituencies. In contrast to the perceptions of Central Asian governments, health-oriented NGOs do not aim to politicise health care. Donor support to Central Asia's health NGOs has created civically oriented actors that fill gaps in the state's capacity and enable governments to better serve their populations.  相似文献

This article examines the preliminary findings of an oral history project on women's working lives in three Irish counties in the period 1936-1960. By employing a feminist analysis of the narratives, the authors endeavour to investigate the extent to which the reality of married women's working lives corresponded with the rhetoric of Irish womanhood generated by political and religious discourses of the day. The analysis reveals that while the women did accept the home-based motherhood role prescribed for them, in many cases financial necessity dictated that they combine this role with that of part-time and in some cases, full-time participation in the labour market.  相似文献

Abstract: This article concerns sexual object choice, transgender subjectivities and emancipatory heterosexuality as imaged in three films: The House of the Spirits (1993), I Like It Like That (1994) and Mi Vida Loca (1994). The author argues, through her examination of the three films, for cinematic ways to refocus and interrogate the look and gender of the gaze, thereby envisioning what the author theorizes as a Latina cinematic subjectivity. The idea of a Latina cinematic subject is presented in order to articulate how at particular moments in the films an autonomous Latina subjectivity is created through narrative and mise-en-scène. It is at these narrative and aesthetic moments that the characters look back at the objectifying gaze, thereby creating a cinematic sexual subjectivity for the characters and a model of agency for the culturally resistant spectator who is doing the looking. The House of the Spirits points to the contradiction of sexual object choice and female desire; I Like It Like That reveals the performative and fluid possibilities of gender, as well as the hybridity of black and Latino cultures; and Mi Vida Loca reflects the struggle for agency in Chicana heterosexual relationships and in their material lives. The author argues that the three portrayals begin important cultural work in the rethinking of sexualities, as they unthink the rigidity of monosexuality, destabilize normative conceptions of gender and reinvigorate agency and egalitarianism in heterosexual relations.  相似文献
