The timing of first sexual intercourse is often defined in terms of chronological age, with particular focus on “early” first sex. Arguments can be made for a more nuanced concept of readiness and appropriateness of timing of first intercourse. Using data from the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), conducted in 2010–2012, this study examined whether a context-based measure of first intercourse—termed sexual competence—was associated with subsequent sexual health in a population-based sample of 17-to 24-year-olds residing in Britain (n = 2,784). Participants were classified as “sexually competent” at first intercourse if they reported the following four criteria: contraceptive protection, autonomy of decision (not due to external influences), that both partners were “equally willing,” and that it happened at the “right time.” A lack of sexual competence at first intercourse was independently associated with testing positive for human papillomavirus (HPV) at interview; low sexual function in the past year; and among women only, reported sexually transmitted infection (STI) diagnosis ever; unplanned pregnancy in the past year; and having ever experienced nonvolitional sex. These findings provide empirical support for defining the nature of first intercourse with reference to contextual aspects of the experience, as opposed to a sole focus on chronological age at occurrence. 相似文献

This article draws on a study of the outcomes and impact of independent advocacy for children and young people to explore how the value of advocacy is understood by them and by professionals, and what differences advocacy can make to the lives of children and young people. Findings indicate that outcomes of advocacy can be significant and wide‐ranging, including both direct effects on the child or young person and wider impact on services. This has implications for how to capture and report the outcomes of advocacy, for which this article offers a new conceptual framework. 相似文献

We investigate the estimation of specific intrinsic volumes of stationary Boolean models by local digital algorithms; that is, by weighted sums of local configuration counts. We show that asymptotically unbiased estimators for the specific surface area or integrated mean curvature do not exist if the dimension is at least two or three, respectively. For three‐dimensional stationary isotropic Boolean models, we derive asymptotically unbiased estimators for the specific surface area and integrated mean curvature. For a Boolean model with balls as grains, we even obtain an asymptotically unbiased estimator for the specific Euler characteristic. 相似文献

Social media provide new opportunities for politicians, such as personalized communication directed at specific communities of interest. Yet despite potential benefits, empirical analyses show that politicians tend to shy away from an active engagement of online audiences. This study explores the effect of politicians’ online boundary management on their use of social media. Ties maintained through social media profiles can be embedded in diverse social contexts (‘context collapse’). Professional communicators, especially, are faced with the challenge of managing boundaries between professional and private online self-presentations. Based on a survey of 106 German members of parliament, we distinguish four types of boundary management strategies. We analyze the effects of these strategies on politicians’ social media use practices – and find that considering boundary management strategies allows for a better understanding of politicians’ online engagement (or lack thereof). 相似文献

Nearly half of all first‐time undergraduates take a loan to pay for college, and many students will borrow tens of thousands of dollars by the time they leave. Low‐income students and students of color borrow student loans more often and in larger amounts, yet attend less selective institutions, are more likely to drop out with debt. Among students who complete college, those with larger amounts of debt may struggle to pay back their loans or to invest in a house, family, or future education. Researchers are just beginning to untangle how the availability and use of student loans affects college access, educational attainment, and life after college, yet this topic has important implications for economic inequality and social stratification. In this article, we summarize what is known and what remains to be investigated, about the impact of student loan availability and use on college enrollment, degree completion, and postcollege outcomes. 相似文献

ABSTRACTThis article examines the effects of “tacit” expectations about race, which are institutionalized in an Interaction Order that frames how we “see” high-status occupational identity. There is an essential moment in presenting Self before Other(s) when it is the turn of the Other(s) to recognize, respond to, and ratify that presentation. The Self is a social accomplishment that requires mutual cooperation from others. Failure to recognize and ratify competent presentations of self, reported frequently by black men, can strip those presentations of the social identity they claim and the dignity, power, and authority associated with that identity. We argue that these “tacit” expectations about identity follow black men wherever they go—no matter how successful they are. Using accounts drawn from interviews, we examine the persistent failure of Others to recognize and ratify high-status black male identities and the legitimate authority they carry. 相似文献

Despite the advent of social media and increasing use of smart phone technology amongst global and UK populations, APP’s for social work remain in their infancy. Several have been developed which focus on the education of social workers and practitioners providing information on specific social work issues, and one we are aware of that explores ethics and values using a games-based approach. In this paper, we discuss the importance of service user perspective in social work practice and how this informed the development of the feedback App. We reflect on developing this instrument using digital technologies which social workers can use to gather anonymous feedback from service users about their experiences of social work interventions. This project, developed in response to demands placed on social work agencies to evidence the effectiveness of service interventions, provide robust data from service users for inspection regimes and sustain service user involvement in improving services. The evaluation model is designed to document the implementation process, exploring what works and what barriers, challenges and lessons were learned by the project team together with how some of the tensions in the process were addressed and resolved. 相似文献

This article shows that First Nations children diagnosed with autism in British Columbia, Canada are under-represented in publications regarding autism and the prevalence thereof, and that this group appears to be under-detected. The aim of this review of publications regarding autism and aboriginal populations in Canada and other countries is to examine possible explanations. The research review results suggest that possible reasons for under-detection of autism among aboriginal populations, and consequently First Nations peoples, can be diagnostic substitution and symptom presentation, ethnic or cultural, area of residence or the impact of historical oppression and discrimination. 相似文献
