Little research has explored linkages between work conditions and mental health in working‐class employed parents. The current study aims to address this gap, employing hierarchical linear modeling techniques to examine how levels of and changes in job autonomy, job urgency, supervisor support, and coworker support predicted parents' depressive symptoms in a sample of 113 dual‐earner couples interviewed five times across the transition to parenthood. Increases in job autonomy and decreases in job urgency predicted fewer depressive symptoms in fathers at 1 year postpartum. For mothers, coworker support predicted fewer depressive symptoms, and supervisor support mitigated the negative effects of job urgency on depressive symptoms. Higher work hours coupled with low job urgency predicted declines in mothers' depressive symptoms across the first year of parenthood. Our findings suggest that interventions that lead to greater autonomy, less job urgency, and more supportive work relations may enhance employee well‐being among working‐class families.  相似文献

Objectives: Popular media and research have predominately focused on the risks of hooking up, which may stigmatize young people. In the current study, we identify factors that facilitate positive hookups. Methods: College students (N = 250) in the United States reported hookup motives, sexual self-concept, sexual satisfaction, and emotional reactions to a hookup. Results: Emotional reactions were more positive than negative. Intimacy and pleasure motives predicted sexual satisfaction; self-affirmation motives predicted positive emotional reactions. Hookups with a previous partner were rated as more satisfying. Conclusions: Understanding qualities associated with positive hookups may better equip young adults to make informed decisions about their sexual lives.  相似文献

College students' ecstasy (MDMA) use increased significantly in recent years, yet little is known about these students. In this study, the authors used the Center for Alcohol and Other Drug Studies (CORE) survey to compare 29 college students who had used ecstasy and other illicit drugs with 90 students who had used marijuana and no other illicit drugs. They noted differences in age, frequency of alcohol and marijuana use, average age of onset of marijuana use, frequency of negative consequences associated with substance use, perceptions of peer norms' drug use, perceived peer acceptance of substance use, and risk perception of substance use. When they entered polysubstance use as a covariate, many of these correlates became nonsignificant. The authors suggest that college ecstasy initiators may be a cohort of marijuana users who tend to engage in multiple risk-taking behaviors. This study serves as a preliminary effort to better understand college students who use ecstasy recreationally.  相似文献

Belief in color-blind ideology among 200 social service providers and its associations with their evaluations of a fictionalized minority family were examined. Perceptions of the family in the first scenes of the movie Crooklyn included the mother’s competency, abusiveness, supportiveness, and irresponsibility, as well as her children’s respectfulness, obedience, lack of control, and aggressiveness. Color-blind ideology was operationalized as participants’ reported degree of belief that differences should be ignored when encountering others. Significant associations were found between degree of belief in ignoring differences and perceptions of the children as aggressive and out of control. Therefore, as the tendency to believe in ignoring differences increased, the tendency to see the Crooklyn children as aggressive and out of control also increased. Imposing color-blind ideologies when evaluating minority children may be associated with increasingly negative perceptions, and therefore may not be in the children’s best interest. Implications for improving social service provision also are discussed.  相似文献

This study developed dose response models for determining the probability of eye or central nervous system infections from previously conducted studies using different strains of Acanthamoeba spp. The data were a result of animal experiments using mice and rats exposed corneally and intranasally to the pathogens. The corneal inoculations of Acanthamoeba isolate Ac 118 included varied amounts of Corynebacterium xerosis and were best fit by the exponential model. Virulence increased with higher levels of C. xerosis. The Acanthamoeba culbertsoni intranasal study with death as an endpoint of response was best fit by the beta‐Poisson model. The HN‐3 strain of A. castellanii was studied with an intranasal exposure and three different endpoints of response. For all three studies, the exponential model was the best fit. A model based on pooling data sets of the intranasal exposure and death endpoint resulted in an LD50 of 19,357 amebae. The dose response models developed in this study are an important step towards characterizing the risk associated with free‐living amoeba like Acanthamoeba in drinking water distribution systems. Understanding the human health risk posed by free‐living amoeba will allow for quantitative microbial risk assessments that support building design decisions to minimize opportunities for pathogen growth and survival.  相似文献

Our exploratory research into contemporary PR practice in Vietnam is underpinned by 12 semi-structured interviews with senior Vietnamese PR executives from various agencies. We selectively use professionalism as an underlying theoretical framework to explore key areas of PR as a profession in Vietnam by considering the impact of environmental variables such as culture and the media system. This paper provides a current snapshot of how an industry introduced by Western multinational corporations has adapted to the Vietnamese context.  相似文献

Elizabethkingia spp. are common environmental pathogens responsible for infections in more vulnerable populations. Although the exposure routes of concern are not well understood, some hospital-associated outbreaks have indicated possible waterborne transmission. In order to facilitate quantitative microbial risk assessment (QMRA) for Elizabethkingia spp., this study fit dose–response models to frog and mice datasets that evaluated intramuscular and intraperitoneal exposure to Elizabethkingia spp. The frog datasets could be pooled, and the exact beta-Poisson model was the best fitting model with optimized parameters α  = 0.52 and β = 86,351. Using the exact beta-Poisson model, the dose of Elizabethkingia miricola resulting in a 50% morbidity response (LD50) was estimated to be approximately 237,000 CFU. The model developed herein was used to estimate the probability of infection for a hospital patient under a modeled exposure scenario involving a contaminated medical device and reported Elizabethkingia spp. concentrations isolated from hospital sinks after an outbreak. The median exposure dose was approximately 3 CFU/insertion event, and the corresponding median risk of infection was 3.4E-05. The median risk estimated in this case study was lower than the 3% attack rate observed in a previous outbreak, however, there are noted gaps pertaining to the possible concentrations of Elizabethkingia spp. in tap water and the most likely exposure routes. This is the first dose–response model developed for Elizabethkingia spp. thus enabling future risk assessments to help determine levels of risk and potential effective risk management strategies.  相似文献
