Alcohol and marijuana use are thought to increase sexual risk taking, but event-level studies conflict in their findings and often depend on reports from a limited number of people or on a limited number of sexual events per person. With event-level data from 1,856 sexual intercourse events provided by 297 college women (M age = 18 years; 71% White), we used multilevel modeling to examine associations between alcohol and marijuana use and condom use as well as interactions involving sexual partner type and alcohol-sexual risk expectancies. Controlling for alternative contraception use, partner type, regular levels of substance use, impulsivity and sensation seeking, and demographics, women were no more or less likely to use condoms during events involving drinking or heavy episodic drinking than during those without drinking. However, for drinking events, there was a negative association between number of drinks consumed and condom use; in addition, women with stronger alcohol-sexual risk expectancies were marginally less likely to use condoms when drinking. Although there was no main effect of marijuana use on condom use, these data suggest marijuana use with established romantic partners may increase risk of unprotected sex. Intervention efforts should target expectancies and emphasize the dose-response relationship of drinks to condom use.  相似文献

“Hookups” are sexual encounters between partners who are not in a romantic relationship and do not expect commitment. We examined the associations between sexual hookup behavior and depression, sexual victimization (SV), and sexually transmitted infections (STIs) among first-year college women. In this longitudinal study, 483 women completed 13 monthly surveys assessing oral and vaginal sex with hookup and romantic partners, depression, SV, and self-reported STIs. Participants also provided biological specimens that were tested for STIs. During the study, 50% of participants reported hookup sex and 62% reported romantic sex. Covariates included previous levels of the outcome, alcohol use, impulsivity, sensation seeking, and romantic sex. Autoregressive cross-lagged models showed that, controlling for covariates, hookup behavior during college was correlated with depression, Bs = .21, ps < .05, and SV, Bs = .19, ps < .05. In addition, precollege hookup behavior predicted SV early in college, B = .62, p < .05. Hookup sex, OR 1.32, p < .05, and romantic sex, OR 1.19, p < .05, were associated with STIs. Overall, sexual hookup behavior among college women was positively correlated with experiencing depression, SV, and STIs, but the nature of these associations remains unclear, and hooking up did not predict future depression.  相似文献

On the basis of theories of maternal identity development, role conflict, and childbearing motivation, the authors tested whether high educational aspirations among pregnant adolescents are related to the unwantedness of the pregnancy and whether pregnancy unwantedness leads to subsequent parenting stress and inadequacy. Longitudinal data from 100 first‐time‐pregnant, unmarried Latina adolescents (M age = 17.3 years) were analyzed. Results from structural equation path modeling confirmed these associations, with strong educational ambitions related to greater unwantedness of the pregnancy, which led to feeling trapped by parenting at 6 months postpartum, which in turn was related to unaffectionate parenting and feeling inadequate in mothering at 1 year postpartum. The potential long‐term negative consequences of high educational aspirations for pregnant adolescents' adjustment to parenting are discussed.  相似文献

Employee Assistance Programs (EAPs) are workplace resources available to employees with problems impacting work performance. EAPs are well-positioned to address intimate partner violence (IPV), a major public health problem with workplace impacts. A purposeful sample of 28 EAPs across the United States was surveyed to identify policies and programs to address IPV, including perpetration. Most EAPs did not report having standardized approaches for addressing IPV perpetration. EAPs also described significant barriers to identifying IPV perpetrators, with the majority relying on self-disclosure on the part of the perpetrator when contacting the EAP. These results suggest that many EAPs--even when interacting with employees who present with issues known to correlate with IPV--are missing a potential opportunity to assess and intervene with IPV perpetrators.  相似文献

The way that nonprofits respond to funding uncertainty is crucial to their ability to meet goals and position themselves for future success. This article investigates how structural, managerial, and financial characteristics affect the adaptive tactics used by human service nonprofits during times of financial stress. These tactics include adding new programs, reducing programs or staff, expanding or starting joint programs, pursuing earned income, and expanding advocacy involvement. Using longitudinal data on human service nonprofits collected on either side of the 2002–2003 economic downtown, we find that larger size provides organizations with a unique ability to choose among different adaptive tactics, as larger size was significantly predictive of adding new programs, reducing programs, expanding advocacy, and pursuing earned income. Strategic planning was positively associated with innovative tactics such as starting joint programs or pursuing earned income. Financial stress or declines in an organization's major funding source led to cutbacks, as expected, but managers who foresaw these challenges were able to respond proactively by adding programs or starting joint programs. However, managers with more training did not respond much differently than did other managers, and organizational age and use of performance management tools had no effect in guiding organizational responses to financial uncertainty.  相似文献

The fast aging of many western and eastern societies and their increasing reliance on information technology create a compelling need to reconsider older users' interactions with computers. This paper summarizes the results of 6 years of research on the age-differentiated design of human-computer interaction. The well-known model of human information processing served as the theoretical framework. The model components 'sensory processing', 'perception', 'working memory', 'decision and response selection' and 'response execution' were analyzed exemplarily in task settings on project management. In seven empirical studies with a total number of 405 participants between 20 and 77 years the human-computer interaction was analyzed regarding effectiveness, efficiency and user satisfaction. For most but not all studies the results reveal that age-induced differences in human-computer interaction can best be compensated by an ergonomic 'design for all'. In some cases however an age-specific approach is favorable.  相似文献

Many scholars pinpoint the family as one of the most important loci of class differences and see parenting in particular as a mechanism for the reinforcement and reproduction of class variation. In this article, the authors explore the role of educational background, occupations, family resources, state surveillance, and culture in explaining how and why parenting practices vary by class backgrounds. The article reviews research that focuses on class‐based cultural norms and values, as well as research that argues that structural conditions and access to resources are more important than culture in influencing parenting norms, beliefs, and outcomes. The authors then discuss recent research that suggests that rather than seeing culture and structure as dichotomous, in fact, culture and structure are intertwined and it is through seeing them as mutually reinforcing factors that we can best make sense of class‐related parenting differences.  相似文献
