There is strong evidence that chronic, systemic inflammation hastens onset of the diseases of old age that ultimately lead to death. Importantly, several studies suggest that childhood adversity predicts chronic inflammation. Unfortunately, this research has been plagued by retrospective reports of childhood adversity, an absence of controls for adult stressors, and a failure to investigate various competing models of the link between childhood adversity and chronic inflammation. The present study was designed to address these limitations. Using 18 years of data collected from 413 African Americans (58% female) included in the Family and Community Health Study, hierarchical regression analyses provided support for a nuanced early life sensitivity explanation for the link between early adversity and adult chronic inflammation. Controlling for health risk behaviors and adult SES, late childhood (ages 10–12) adversity amplified the association between adult adversity (age 29) and chronic inflammation. This interaction operated in a domain-specific fashion. Harsh parenting amplified the relation between intimate partner hostility and inflammation, whereas early discrimination amplified the relation between adult discrimination and inflammation. These findings suggest that individuals may be primed to respond physiologically to adverse adult circumstances that resemble those experienced earlier in life.

This study investigated the association between risky sexual behavior and drug use among female youth sentenced to a regional juvenile detention center. Preincarceration behavioral health risk data were collected from a modified version of the Youth Risk Behaviors Surveillance Survey completed by respondents. Almost all of the 105 participants had been detained before their current sentence, more than half of them were sexually active before the age of 13, and 70% had smoked marijuana or drank alcohol by age 14. A regression analysis was conducted to determine if preincarceration sexual health risk behaviors were significant enough to predict continued risk behaviors related to pregnancy, disease prevention, and substance use. Findings indicate that youth detention-based prevention programs should emphasize sexual and drug-risk reduction strategies as a means to reduce risky behaviors for this population.  相似文献

This article explores recent developments in masculinity, focusing on the sexualisation of fatherhood in Anglophone media. As it becomes socially acceptable for men to engage with “hands-on” fatherhood roles that had previously been primarily associated with motherhood, the appeal lies not just in this shift in gendered performance, but the representation of this as an opportunity for men to reveal a desirably body image. Where previously the hands-on fatherhood role had been glossed as “nappy changing duties,” this more recent development focuses on men’s bodies and in particular the act of carrying a young child which affords the chance for biceps to be flexed in juxtaposition with the gentle act of holding a child. Colloquially, this has led to the emergence of the “DILF,” particularly on social media where sites are devoted to photos of such men.  相似文献

Abstract

Politicians, diplomats and analysts commonly assume that commitment to multilateralism and liberal norms is part of the EU’s very DNA. Increasingly, however, the EU’s commitment to the liberal global order is more selective. We demonstrate the shift to a more contingent liberalism by examining the EU’s recent record in relation to four different challenges: international trade; US leadership; Russian actions in the eastern neighbourhood; and security in the Middle East. We speculate on what this may portend for the EU’s self-identity, European interests and the integrity of the prevailing global order.  相似文献

Opportunistic electoral fiscal policy cycle theory suggests that all subnational officials will raise fiscal spending during elections. Ideological partisan fiscal policy cycle theory suggests that only left‐leaning governments will raise election year fiscal spending, with right‐leaning parties choosing the reverse. This article assesses which of these competing logics applies to debt policy choices. Cross‐sectional time‐series analysis of yearly loan acquisition across Mexican municipalities—on statistically matched municipal subsamples to balance creditworthiness across left‐ and right‐leaning governments—shows that all parties engage in electoral policy cycles but not in the way originally thought. It also shows that different parties favored different types of loans, although not always according to partisan predictions. Both electoral and partisan logics thus shape debt policy decisions—in contrast to fiscal policy where these logics are mutually exclusive—because debt policy involves decisions on multiple dimensions, about the total and type of loans.  相似文献

Perspectives on disability originating from non-Western cultures are beginning to appear in disability literature, however discussions may become lost in rhetoric unless grounded in experiences of people with disabilities themselves. The purpose of this study was to investigate the lived experience of physical disability in Timor Leste with the assistance of a group of Timorese participants with disabilities who were employed in the disability sector. These participants recounted experiences of disability from their own lives together with their observations of people with disabilities living in remote parts of Timor Leste who often lived with stigma or deprivation. The participants thus described their own lived experiences against a backdrop of a non-Western culture. A picture emerged of a stigmatising culture where acceptance of disability is uncommon yet where significant attempts are being made to change attitudes to disability within the culture of Timor Leste.  相似文献

China’s rise as a (re)emerging donor has attracted attention over the last decade, with a focus on Chinese development assistance as a challenge to the Organisation for Economic Cooperation and Development (OECD) aid norms. Knowledge of China’s domestic aid structure is needed to understand Chinese aid abroad. This paper addresses gaps in the literature and challenges the accepted nostrum that China’s Ministry of Commerce (MOFCOM) dominates China’s aid programme. Building on the authors’ experience as Chinese aid practitioners and scholars over more than a decade and drawing on over 300 interviews, the paper explores China’s aid decision-making processes by examining the main agencies, identities and informal interactions. We argue that the Chinese aid system is characterised by fierce and ongoing competition for influence among actors, especially MOFCOM, the Ministry of Foreign Affairs (MFA) and the Ministry of Finance (MoF), as well as the companies responsible for implementing Chinese aid projects.  相似文献

During the last decade, several formalized approaches have been developed to improve the effectiveness of probation and parole by implementing evidence-based research into community supervision practices. A key component of these new approaches are the use of officer coaching sessions, which are designed to improve officer fidelity in the core correctional skill areas. This study explores the impact of an initial training and monthly coaching sessions in the Effective Practices in Community Supervision (EPICS) model on probation and parole officer use of core correctional skills. The results examine the average quarterly officer use of skills over an 18-month follow-up period based on training status (i.e., trained versus untrained officers) in the EPICS model. This study adds to the understanding of the role training and coaching may play in improving officer use of core correctional skills. Policy implications and recommendations for future research are also discussed.  相似文献
