The present study investigated possible ethnic contributions to overly positive self‐perceptions in middle childhood. The goals of this study were threefold. First, the present study sought to replicate the intriguing findings reported by Zakriski and Coie that African American children overestimate their acceptance, and European American children underestimate acceptance by other‐ethnicity peers. Second, this study examined possible explanations for ethnic differences in the pattern of perceptual bias. Finally, this study extended prior research by examining ethnic differences in the accuracy of children's perceived peer acceptance. Archival data consisting of 826 children in third (N = 284), fourth (N = 241), and fifth grades (N = 301) were used in the present investigation; 237 of which were African American children, and 589 were European American children. Results of this study replicated the findings of Zakriski and Coie . Moreover, African Americans' overestimation and European Americans' underestimation of acceptance by other‐ethnicity peers was found to be attributable to more positive views of self and others among African American children relative to European American children. Finally, children were found to be more accurate about judging their acceptance by peers of the same ethnicity than those of a different ethnicity. Possible explanations of what causes African American children to have more positive views of self and others than European American children are discussed. 相似文献

Objective: Behaviors of weight conscious drinkers (BWCD) include disordered eating, excessive physical activity (PA), and heavy episodic drinking. Considering that approximately 25% of the college students report BWCD, it is important to investigate what characteristics increase the likelihood of college students engaged in BWCD for both moderate and vigorous PAs. Participants: A total of 510 college students were recruited from a large, public southeastern university. Methods: Participants completed a cross-sectional survey during the spring 2015 semester. Results: Of 510 respondents, 11.2% reported moderate PA-based BWCD and 14.7% reported vigorous PA-based BWCD. Weight loss intention, BMI and Greek affiliation predicted both moderate and vigorous BWCD. Conclusions: Study findings suggest that Greek-affiliated students and students with weight loss intentions might be at an increased risk for BWCD. Along with promoting lower levels of alcohol consumption, college practitioners should consider discussing issues of weight and body image with college students as they relate to maladaptive drinking behavior. 相似文献

A framework for the analysis of manufacturing systems operating under a production authorization card (PAC) system is outlined. The PAC system provides a single model, which encompasses a broad variety of control strategies, including Kanban and CONWIP. This paper describes a framework for the performance analysis and comparison of both specific and families of control strategies. The framework starts with system performance measures estimated by simulation. These simulations in turn provide training data for neural network metamodels. The metamodels allow for a variety of analysis and optimization approaches, including the construction of optimal policy curves, which can provide considerable insight into the systems under study. 相似文献

ABSTRACTThis qualitative study examines how mid-life gay and lesbian married individuals articulate their decision to marry. Using 2013 data from 30 mid-life couples in Massachusetts, this study challenges previous literature that conceptualized marriage as entirely positive or negative for same-sex individuals. Mid-life individuals’ unique social and historical context influence their experiences of marriage, as mid-life individuals have witnessed the rise and feasibility of marriage equality, have formed relationships outside of the bounds of marriage, and have been in committed relationships long before they married. Using the framework of ambivalence, our findings provide three main contributions to the literature. First, we show that marital ambivalence is a common experience in our sample. Second, we detail how marital ambivalence is indicative of the age, life-course stage, and length of relationship for mid-life lesbian and gay individuals. Third, we explore ambivalence at the level of the relationship, not just as an individual experience. This study provides new insight into how sexuality shapes both intimate relationship dynamics as well as the effect of same-sex marriage on LGBT communities and identities. 相似文献

The current older adult population is more likely to need and seek treatment for alcohol and drug abuse than previous cohorts of older adults, which necessitates the need for age-appropriate substance use treatment. Building on previous research that examined the lack of attention on substance use among older adults, this study examines articles addressing substance use disorders among older adults in leading gerontological and substance abuse journals and federal funding between 2011 and 2017. Publications were identified from ten leading gerontological and ten leading substance abuse journals using Medical Subject Heading (MeSH) terms. During this time-period, there were 68 and 44 articles published in gerontology and substance abuse journals respectively related to substance use disorders in older adults. Most (59.8%) addressed alcohol abuse and 7% involved intervention studies. In the 7-year period, there were 13 federal grants. A paucity of published or funded work exists in this area despite growing misuse and treatment seeking among older adults with substance use disorders. Effectively addressing substance abuse in older adults will require a coordinated effort between researchers and practitioners to establish and implement best practices for practitioners to rely on when working with substance abusing older adults. 相似文献
