Preschool children's sleep was examined as a moderator of the association between negative emotionality and both peer acceptance and peer rejection. Participants were 115 children (47 percent girls, M age = 4.29 years, SD = .63). Preschool teachers reported on children's negative emotionality (anger/frustration, sadness, and fear). Sleep was measured objectively using actigraphy in the child's home for seven consecutive nights. Peer acceptance and rejection were assessed using children's choices in sociometric interviews. Controlling for potential confounds, moderation analyses revealed that negative emotionality predicted peer acceptance and rejection only among children with poorer sleep quality (lower sleep efficiency, more frequent wake episodes, longer sleep latency), but not better sleep quality. Findings suggest that sleep is important not only for predicting child functioning but also for moderating the adverse effects of negative emotionality on a salient indicator of interpersonal functioning for preschool age children.  相似文献

Lay perceptions of risk appear rooted more in heuristics than in reason. A major concern of the risk regulation literature is that such “error‐strewn” perceptions may be replicated in policy, as governments respond to the (mis)fears of the citizenry. This has led many to advocate a relatively technocratic approach to regulating risk, characterized by high reliance on formal risk and cost‐benefit analysis. However, through two studies of chemicals regulation, we show that the formal assessment of risk is pervaded by its own set of heuristics. These include rules to categorize potential threats, define what constitutes valid data, guide causal inference, and to select and apply formal models. Some of these heuristics lay claim to theoretical or empirical justifications, others are more back‐of‐the‐envelope calculations, while still more purport not to reflect some truth but simply to constrain discretion or perform a desk‐clearing function. These heuristics can be understood as a way of authenticating or formalizing risk assessment as a scientific practice, representing a series of rules for bounding problems, collecting data, and interpreting evidence (a methodology). Heuristics are indispensable elements of induction. And so they are not problematic per se, but they can become so when treated as laws rather than as contingent and provisional rules. Pitfalls include the potential for systematic error, masking uncertainties, strategic manipulation, and entrenchment. Our central claim is that by studying the rules of risk assessment qua rules, we develop a novel representation of the methods, conventions, and biases of the prior art.  相似文献

Lesbian, gay, bisexual, and transgender (LGBT) youth experience multiple sexual health inequities driven, in part, by deficits in parental and peer support, school-based sex education programs, and community services. Research suggests that the Internet may be an important resource in the development of sexual health among LGBT youth. We examined the feasibility of recruiting youth in same-sex relationships into an online sexual health intervention, evaluated intervention acceptability, and obtained initial estimates of intervention efficacy. LGBT youth (16 to 20 years old) completed Queer Sex Ed (QSE), an online, multimedia sexual health intervention consisting of five modules. The final sample (N = 202) completed the pretest, intervention, and posttest assessments. The primary study outcomes were sexual orientation identity and self-acceptance (e.g., coming-out self-efficacy), sexual health knowledge (e.g., sexual functioning), relationship variables (e.g., communication skills), and safer sex (e.g., sexual assertiveness). Analyses indicated that 15 of the 17 outcomes were found to be significant (p < .05). Effect sizes ranged from small for sexual orientation (e.g., internalized homophobia) and relationship variables (e.g., communication skills) to moderate for safer sex (e.g., contraceptive knowledge) outcomes. This study demonstrated the feasibility, acceptability, and initial efficacy of QSE, an innovative online comprehensive sexual health program for LGBT youth.  相似文献

Changes in the U.S. telephone system, especially the rapid growthin the prevalence and use of cell phones, raise concerns aboutundercoverage error in random digit dial (RDD) telephone samples.A supplement to the Current Population Survey (CPS) was conductedin 2004 to examine telephone service and usage in U.S. households.This article explores the potential for biases in RDD surveysresulting from the increases in cell phones by presenting estimatesof the percentage of households with different types of telephoneservice, including the percentage of cell-only households, andgiving demographic profiles of households by type of telephoneservice. Logistic regression models examine variables that predictwhether households are without a telephone or only have cellphones. These predictors may be used for weighting adjustmentsto reduce undercoverage biases. We address some additional issues,including the wording of questions for measuring telephone service,that are relevant if telephone-sampling methods are revisedto include cell phones. The estimates from the CPS supplementare also used to help understand some of the new sampling andweighting problems associated with selecting samples from cellphone numbers.  相似文献

In 2003, Idaho selected the Foster PRIDE/ Adopt PRIDE preservice training and resource family development program. PRIDE participants (n = 228) completed a pre and posttest survey based on the PRIDE training competencies in 2004-2005. Results indicate that PRIDE is an effective training and resource family development program. Providing and evaluating foster/ adoptive parent preservice training programs can assist child welfare programs in making a positive difference in the lives of families and children involved in the child welfare system while increased cost-savings by retaining foster/adoptive families over time.  相似文献

Limited data exist analyzing the role of gender in workplace violence in health care settings. This study examined whether different types of threatening incidents with patients (physical, verbal, sexual, or posturing) were salient to male versus female staff across psychiatric settings (inpatient forensic, inpatient acute/chronic psychiatric, and outpatient psychiatric). Results indicated that although women disproportionately experienced sexualized threats, they were not more likely to report such incidents as salient and threatening. The study also assessed the extent to which situational variables contributed to staff's feelings of threat. Results showed that rapport with the patient, quality of relationships with coworkers, and presence of coworkers in the area were not significantly related to how threatened staff felt in a recent threatening incident. Findings are discussed within the context of staff training and organizational benefits.  相似文献

A sample of 292 college students recalled a partner who had engaged in unwanted pursuit (46%) or recalled their most recent "normal" dating relationship. Subjects rated their own level of stalking victimization and rated the partner on a series of personality characteristics and social competence. Unwanted pursuers were perceived as less socially competent, more histrionic, more borderline, and less obsessive-compulsive, with discrimination of "normals" from unwanted pursuers of approximately 75% to 80% accuracy. These attributions also significantly predicted a continuous measure of unwanted pursuit victimization (R = .406). Implications for developing more precise and practical risk profiles of unwanted pursuers are discussed.  相似文献

Using multiple correspondence analysis, data from the US Equal Employment Opportunity Commission (1992-2003) were examined for types and patterns of allegations of discrimination filed by adults with multiple sclerosis (MS) under Title I of the Americans with Disabilities Act (ADA). Women comprised the majority of the Charging Parties (n=687, 67%), and most of the Charging Parties were White (n=769, 76%). The total number of allegations studied (N=3,668) was divided into two datasets, specifically 1,142 occurring separately and 2,526 occurring as part of a multiple allegation set. The four most frequent allegations were related to discharge, reasonable accommodation, terms and conditions of employment, and harassment. Multiple correspondence analysis indicated that a 5 axis model was required to explain approximately 50% of the variance in allegation patterns, and no charging party or employer characteristics were related to the axes. Axis themes derived from perceived discrimination on the part of employers included threats to retention (2 axes), employer hostility, informal or formal employer actions, and barriers to career mobility. Results supported the need for rehabilitation counseling interventions to help adults with MS identify and address precipitants to discharge (involuntary termination) or constructive discharge (voluntary termination in response to an untenable work situation).  相似文献

The organization of charitable distribution channels to ensure donor contributions reach beneficiaries in an efficient manner and the use of accounting metrics of such efficiency (whether provided directly or by charity rating groups) are oft‐discussed issues in the nonprofit sector. The two issues are inextricably linked since reported efficiency measures influence subsequent donor giving. This study develops a parsimonious model of a charity that must decide how best to employ its resources, either by acting as a direct service provider or as a grant provider to organizations that provide services to beneficiaries. We show that the desire to boost perceptions of efficiency vis‐à‐vis accounting reports leads an organization to rely more on others to provide services rather than being a direct service provider. This temptation to expand either the scope or length of the charity supply line is muted by a desire to avoid redundant costs and improve service delivery. The model's results have implications both for the role of nonprofit accounting and observed distribution strategies of nonprofits.  相似文献
