While a growing literature demonstrates the impact of socio-political factors on citizens’ quality of life, scholars have
paid comparatively little attention to the role political organizations such as labor unions play in this regard. We examine
labor organization as a determinant of cross-national variation in life satisfaction across a sample of advanced industrial
polities. Our findings strongly suggest that unions increase the life satisfaction of citizens, and that that this effect
holds for non-union members as well. Moreover, we also find that labor organization has the strongest impact on the subjective
well-being of citizens with lower incomes. We confirm these hypotheses using both individual and aggregate-level data from
fourteen nations. We show these relationships to have an independent and separable impact from other economic, political,
and cultural determinants. The implications for the study of life satisfaction and of labor unions as political actors in
general are discussed. 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

“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

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

This study investigated the association between sexual practices and duration of a sexual encounter. Using data from a population-based computer-assisted telephone survey of 8,656 Australians aged 16 to 64 years, four distinct patterns of sexual practices among respondents were found: "basic sexual encounter" (involving mainly kissing, cuddling, stroking one's partner and being stroked, and vaginal intercourse), "basic sexual encounter plus oral sex," "all assessed sexual practices" (all sexual behaviors included in the survey), and "mainly vaginal intercourse" (characterized by lower levels of kissing, cuddling, and stroking). For both men and women, respondents classified in the basic sexual encounter plus oral sex, and all assessed sexual practices clusters reported significantly longer durations than those in the basic sexual encounter group, whereas respondents in the mainly vaginal intercourse cluster reported shorter durations. These differences were found even after allowing for demographic differences in sexual duration-specifically, age and partner type of the most recent opposite-sex partner. These findings add to the understanding of what typically happens in a sexual encounter. Overall, longer sexual encounters appear to be associated with the inclusion of the least common sexual practices-namely, oral sex and self-stimulation. 相似文献

Black adolescents use less alcohol, on average, than white adolescents. Prior research has struggled to explain the disparity in alcohol use between blacks and whites but not for a lack of potential mediating mechanisms. The current study draws on differential association theory and two waves of panel data (n = 1,016) to examine the influence of interracial friendship, the racial composition of peer groups, and communities on black–white differences in alcohol use. Findings indicate that (1) the racial composition of peer groups and communities influence changes in alcohol use, and (2) racial segregation contributes to racial disparities in alcohol use while interracial friendship reduces these disparities. Results suggest that the socially conservative values of the African‐American community are a strong deterrent to adolescent drinking, affecting even those adolescents who are themselves white but associate with black youth. 相似文献

Intervention research for couples and families managing chronic health problems is in an early developmental stage. We reviewed randomized clinical trials of family interventions for common neurological diseases, cardiovascular diseases, cancer, and diabetes, which is similar to the content of previous reviews discussed later. One overriding theme of these studies is that patients with chronic illnesses and their families face a variety of challenges to which researchers have responded with an array of treatment modalities. Very few of the interventions reviewed, with the exception of treatment for adolescents with diabetes, tested family psychotherapy models. Most interventions were time-limited therapeutic interventions that trained families to improve their communication and problem-solving skills, individual and family coping skills, and medical management. Researchers more clearly described mechanisms of change in intervention studies with cancer and diabetes than with other diseases, and not surprisingly, they found greater empirical support for their interventions. Family interventions show promise to help patients and family members manage chronic illnesses. To develop an empirical base for family approaches to managing chronic illnesses, interventions must be based on theories that delineate mechanisms of change in family processes and skills in medical management necessary to maintain patients' and family members' health. 相似文献

Approaches used by employee assistance programs to address perpetration of intimate partner violence
Walters JL Pollack KM Clinton-Sherrod M Lindquist CH McKay T Lasater BM 《Violence and victims》2012,27(2):135-147
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
