Objectified body consciousness (OBC)—the tendency to view one's body as an object for others to look at and evaluate—is theorized to emerge during sexual maturation as adolescents, particularly adolescent girls, experience sexual objectification. Although OBC generally is discussed in developmental terms, research so far has examined primarily the experiences of undergraduates and adults. Our goal in this study was to examine early adolescent experiences with OBC and to explicitly test the idea that OBC is linked to experiences of sexual objectification, such as peer sexual harassment, that early adolescents face as their bodies reach maturity. We tested several structural models of OBC and its relation to puberty, peer sexual harassment, and negative body experience. The prevailing model supported OBC theory's premise that pubertal development and peer sexual harassment increase adolescent girls' tendency toward self-surveillance, which in turn leads to greater body shame. Several pathways in the model were not significant for boys.  相似文献

This paper reviews the literature concerning the impact of work on reproductive health. In doing so, it offers a framework model for guiding future research and practice. Contemporary models of occupational health usually identify at least two pathways linking exposure to workplace hazards to their effects on health. The study of work-related reproductive health has been largely restricted to the effects of the more tangible and physical hazards of work mediated by a largely physico-chemical pathway. However, the growth of research into the psycho-physiological influence of stress on reproductive health provides a new direction for research in this domain with the exploration of a complementary pathway. The extension of this new approach into the investigation of the effects of work design and management on reproductive health represents a potentially important and further development.  相似文献

While juvenile courts were originally designed to respond to troubled youth by providing treatment appropriate to the needs of individual offenders, advocates of a system that "gets tough" on young criminals by meting out punishments based on offense characteristics (both present offense and past offense history) have become increasingly influential in recent years. In this article, I examine a special case, that of juvenile sex offenders in a Washington State county. for whom a 1990 law reintroduced treatment as a central goal. While Washington has been a forerunner in the shift toward a juvenile justice system in which offending behavior is the central factor in decision making, I argue that, largely as a result of this law, juvenile sex offending has been "medicalized" and that, in this process, distinctions based on offense characteristics have noticeably diminished. This case study provides both empirical support for established theoretical arguments regarding medicalization and a detailed explication of the differences between medical and legal assumptions about social problems.  相似文献

The developmental origins of sharing remain little understood. Using procedures adapted from research on prosocial behavior in chimpanzees, we presented 18- and 25-month-old children with a sharing task in which they could choose to deliver food to themselves only, or to both themselves and another person, thereby making it possible for them to share without personal sacrifice. The potential recipient, a friendly adult, was either silent about her needs and wants or made them explicit. Both younger and older toddlers chose randomly when the recipient was silent. However, when the recipient vocalized her desires 25-month-olds shared whereas younger children did not. Thus, we demonstrate that children voluntarily share valued resources with others by the end of the second year of life, but that this depends on explicit communicative cues about another's need or desire.  相似文献

The Randomized Response (RR) technique is a well-established interview procedure which guarantees privacy protection in social surveys dealing with sensitive items. The RR method assumes a stochastic mechanism to create uncertainty about the true status of the respondents in order to ensure privacy protection and to avoid tendencies to dissimulate or respond in a socially desirable direction. A very general model for the RR method was introduced by Franklin (Commun Stat Theory Methods 18:489?C505, 1989) when a single-sensitive question is under study. However, since social surveys are often based on questionnaires containing more than a single-sensitive question, the analysis of multivariate RR data is of considerable interest. This paper focuses on the generalization of the Franklin model in a multiple-sensitive question setting and on related inferential issues.  相似文献

The European Agency for the Evaluation of Medicinal Products has recently completed the consultation of a draft guidance on how to implement conditional approval. This route of application is available for orphan drugs, emergency situations and serious debilitating or life-threatening diseases. Although there has been limited experience in implementing conditional approval to date, PSI (Statisticians in the Pharmaceutical Industry) sponsored a meeting of pharmaceutical statisticians with an interest in the area to discuss potential issues. This article outlines the issues raised and resulting discussions, based on the group's interpretation of the legislation. Conditional approval seems to fit well with the accepted regulatory strategy in HIV. In oncology, conditional approval may be most likely when (a) compelling phase II data are available using accepted clinical outcomes (e.g. progression/recurrence-free survival or overall survival) and Phase III has been planned or started, or (b) when data are available using a surrogate endpoint for clinical outcome (e.g. response rate or biochemical measures) from a single-arm study in rare tumours with high response, compared with historical data. The use of interim analyses in Phase III for supporting conditional approval raises some challenging issues regarding dissemination of information, maintenance of blinding, potential introduction of bias, ethics, switching, etc.  相似文献

The United States has seen a sizable increase in older worker labour force participation, although how much of this is due to public policy is uncertain. In fact, outside of academic and policy research circles, there has been relatively little attention paid to older workers and the challenges of an aging workforce in that country. Public policymakers have not demonstrated the same interest in expanding employment opportunities for older workers that they have shown for other groups, or that has been seen in other countries. Still, a number of significant pieces of legislation have been enacted over the past several decades that should be making continued employment at later ages easier, more attractive, or more essential financially. This paper examines those policies. However, because of confounding and conflicting influences from elsewhere, public policy initiatives focusing on older worker employment do not appear to be major contributors to rising labour force participation rates at older ages.  相似文献

Adults aging with disabilities comprise a diverse group. In this article, we identify the prevalence and characteristics of this target population, focusing on adults who are dually eligible for Medicare and Medicaid. We articulate challenges in the delivery of health, social, and support services to adults aging with disabilities, particularly how existing health care policy and financing contributes to fragmentation of care. Finally, we identify opportunities for social workers to advocate for and promote system improvements in the delivery of care for aging adults with disabilities in the current climate of health care reform.  相似文献
