Individuals with high body mass index (BMI), negative body image, and unhealthy weight control behaviors may be more likely to engage in high-risk sexual behaviors than others. Researchers have not fully investigated these relationships in a sample of college students. The authors collected data regarding several weight-related issues and high-risk sexual behaviors (response rate = 39%) from 1,168 college students. Over half reported at least 1 high-risk sexual behavior. After the authors controlled for several demographic characteristics, they found that higher BMIs were associated with increased odds of having a casual sexual partner (odds ratio [OR] = 2.70) and being intoxicated at last intercourse (OR = 2.25). Among women, unhealthy weight control behaviors were associated with having a casual partner (OR = 2.12), using no or unreliable contraception (OR = 1.98), and being intoxicated at last intercourse (OR = 2.31). Weight-related issues were not associated with sexual behaviors among college men. The authors describe their findings within two health behavior frameworks, and they discuss implications for research and health education. 相似文献

The relationship between isometric force control and functional performance is unknown. Submaximal steadiness and accuracy were measured during a constant force-matching task at 50% of maximal isometric voluntary contraction (MVC) of the knee extensors in 19 older women (70-89 years). Other variables included MVC, rate of torque development, and EMG activity. Functional performance was assessed during maximal performance of walking endurance, chair rising, and stair climbing. Isometric steadiness (but not accuracy) was found to independently predict chair-rise time and stair-climbing power and explained more variance in these tasks than any other variable. Walking endurance was related to muscle strength but not steadiness. These results suggest that steadiness is an independent predictor of brief, stressful functional-performance tasks in older women with mild functional impairment. Thus, improving steadiness might help reduce functional limitations or disability in older adults. 相似文献

The author presents a paradigmatic categorization and review of the literature that is available regarding lesbians and alcohol. She illuminates the characteristics, shortcomings, and strengths of Empirical Post Positivist, Interpretive, and Critical Social research paradigms. Results of the various studies are presented while research and funding directions are proposed. 相似文献

The present research describes the development and validation of a cognitive assessment instrument, the Drake Beliefs about
Chance (DBC) inventory, designed to determine and quantify erroneous beliefs about games of chance. Principal components analyses
showed that the DBC assesses two primary dimensions, Illusion of Control and Superstition. Correlation analyses showed that
scores on these two dimensions are related to higher frequency of gambling behaviors in both adults from the general population
and clients from gambling treatment centers. Of the two sets of erroneous beliefs, Illusion of Control was a better predictor
of gambling than Superstition. This investigation provides additional evidence that participants in games of chance such as
casino gamblers possess certain classes of erroneous beliefs regarding the games they play. 相似文献

We regard individual unemployment duration as an important determinant of individuals welfare dependence. Welfare receipt is modelled for a unique data set of 4,655 Finnish unemployed individuals. A two-stage binomial hurdle model is applied, and estimations are made by both ML and GMM. Disregarding the full interrelation between unemployment and welfare clearly underestimates the importance of the former. Unemployment has a clear impact on both the probability of welfare participation and on welfare dependence among recipients. Using a finite mixture model we find that there is a small minority of unemployed welfare recipients who are locked-in in welfare dependence.All correspondence to Maria Melkersson.

Ubiquitinated proteinaceous inclusions are the hallmark of many neurodegenerative diseases. Inefficient proteolysis might lead to the accumulation and ultimate deposition of potentially toxic entities as inclusions within neurons or glial cells. This hypothesis is supported by genetic evidence both from patient populations and from engineered mutations in genes that encode ubiquitin/proteasome components in mice. The appearance of similar inclusions in the brains of elderly individuals of normal and subclinical conditions begs the question of whether there is a general age-related decline in the ability of the ubiquitin/proteasome pathway (UPP) to recognize and eliminate abnormal proteins, and whether such a decline would be reflected by changes in the abundance or activity of some or all components of the UPP. Here we describe alterations in the aging mammalian brain that correlate with a decline in the function of the UPP and review the evidence for age-related changes in specific UPP components. These alterations are discussed within the context of prevalent theories of aging. 相似文献

This article describes collaboration among a university, a state child welfare agency, and a Native American community organization to develop a culturally driven practice model for urban, Native American child welfare. The approach includes a strategy to build resources to serve Native American clients, a training program for child welfare and court personnel using a culturally responsive curriculum, and an advocacy program that monitors for Indian Child Welfare Act compliance and provides assistance to child welfare workers and the court. The discussion identifies challenges and opportunities in addressing the needs of urban Native American communities. The article concludes with principles for culturally responsive practice for urban Native American child welfare practice. 相似文献

The gap between the number of children of color in care and the recruitment of minority foster and adoptive homes has triggered growing support for transracial adoption, culminating in the Multi-Ethnic Placement Act (MEPA) and the Interethnic Adoption Provisions (IEP) legislation. Although MEPA and IEP focus on eliminating barriers to transracial placements, they do not address support for families that choose to adopt transracially. A lack of professional literature exists in this area. This study explores a number of trans-racial placements and adoptions, with the goal of identifying, from the perspective of the families interviewed, potential services that would enhance such placements and adoptions. 相似文献

Children in the care and custody of the state are increasingly placed with kin rather than in unrelated foster homes. Current estimates suggest that 400,000 children are in kinship care arrangements, with a projected increase to over a half million by 1995 (Center for the Study of Social Policy, 1990). This article provides an overview of the trend toward increasing use of kinship care for foster children and the reasons for this development. It then presents the case management models currently used in kinship care cases by two large public child welfare agencies, and it concludes with discussion of these models and their implications. 相似文献
