Because similarity between partners has been thought to be related to relationship quality, this study assessed similarities between partners in 44 married, 35 heterosexual cohabiting, 50 gay, and 56 lesbian couples on demographic characteristics, appraisals of relationship quality, and factors predictive of relationship quality. With regard to demographic characteristics: Partners' age was correlated for each type of couple; partners' income, education, and job prestige were correlated only for heterosexual cohabiting couples; and gay partners had the largest discrepancies in age, income, and education. With regard to appraisals of relationship quality: Partners' scores were correlated for each type of couple on relationship satisfaction but for only gay and lesbian couples on love for partner; partners across all couples differed in their assessments of relationship quality. With regard to the predictors of relationship quality: Partner scores were correlated for each type of couple only on shared decision making; these predictor scores were most frequently correlated for lesbian partners; differences between partners were least for lesbian couples on attractions to the relationship and perceived family support and greatest for cohabiting couples on dyadic attachment. Relationship quality was not related to discrepancies between partners' demographic variables but was negatively related to discrepancies in partners' dyadic attachment. In conclusion, partner homogamy was most pervasive in lesbian couples, and for all couples homogamy on dyadic attachment was related to relationship quality.  相似文献

Less than two months after 11 September 2001, and a few weeks after the beginning of the US bombing campaign in Afghanistan, President George W. Bush made an urgent plea to see Iranian filmmaker Mohsen Makhmalbaf's Kandahar. Not only did the President want to see Kandahar; he encouraged US citizens to view it as well. This article offers two readings of Kandahar – the first suggestive of what its filmmaker Makhmalbaf saw in Afghanistan and the second suggestive of what Bush saw (or hoped to see) in Makhmalbaf's Afghanistan. In particular, this article focuses on how the Bush administration – against the intentions of Kandahar's director and star – propelled occidental subjects to ‘lift the veil’ on Afghanistan and on Afghan women by viewing Kandahar as if it positioned the feminine as a needy and willing object of US rescue. It was in part by laying this particular claim to the separated sisters of Kandahar that the Bush administration constructed a humanitarian US ‘we’ as among the foundations of its ‘moral grammar of war’ in the war on terror.  相似文献

Understanding why some national‐origin groups excel in school while others do not is an enduring sociological puzzle. This paper examines whether the degree of immigrants’educational selectivity ‐ that is, how immigrants differ educationally from non‐migrants in the home country ‐ influences educational outcomes among groups of immigrants’children. This study uses published international data and U. S. Census and Current Population Survey data on 32 immigrant groups to show that as immigrants’educational selectivity increases, the college attainment of the second generation also increases. Moreover, the more positive selection of Asian immigrants helps explain their second generations’higher college attendance rates as compared to Europeans, Afro‐Caribbeans, and Latinos. Thus, the findings suggest that inequalities in relative pre‐migration educational attainments among immigrants are often reproduced among the next generation in the United States.  相似文献

Recently, there has been a great deal of research on the socialization of children's emotions and self‐regulation. In the present study, the specific strategies that mothers use to help their young children regulate their emotional responses were examined using a longitudinal design. Forty‐three mother–toddler pairs were observed when toddlers were both 18 and 30 months of age, and mothers’ attempts to regulate their toddlers’ emotions during several emotion‐eliciting tasks were transcribed from videotape. When the children were 5 years old, their responses to a disappointment task were observed. Results indicated a relation between mothers’ regulation strategies in toddlerhood and children's facial and behavioral responses to the disappointment task measured at 5 years of age. Specifically, mothers’ use of regulation strategies at 30 months, but not at 18 months, was positively related to children's appropriate emotional displays in response to disappointment. Moreover, the specific types of strategies that mothers used had differential associations to children's responses to disappointment. Findings are discussed in terms of the potentially important role of mothers’ behaviors in the development of children's emotion self‐regulation.  相似文献

β-Chloroprene is used in the production of polychloroprene, a synthetic rubber. In 2010, Environmental Protection Agency (EPA) published the Integrated Risk Information System “Toxicological Review of Chloroprene,” concluding that chloroprene was “likely to be carcinogenic to humans.” This was based on findings from a 1998 National Toxicology Program (NTP) study showing multiple tumors within and across animal species; results from occupational epidemiological studies; a proposed mutagenic mode of action; and structural similarities with 1,3-butadiene and vinyl chloride. Using mouse data from the NTP study and assuming a mutagenic mode of action, EPA calculated an inhalation unit risk (IUR) for chloroprene of 5 × 10−4 per µg/m3. This is among the highest IURs for chemicals classified by IARC or EPA as known or probable human carcinogens and orders of magnitude higher than the IURs for carcinogens such as vinyl chloride, benzene, and 1,3-butadiene. Due to differences in pharmacokinetics, mice appear to be uniquely responsive to chloroprene exposure compared to other animals, including humans, which is consistent with the lack of evidence of carcinogenicity in robust occupational epidemiological studies. We evaluated and integrated all lines of evidence for chloroprene carcinogenicity to assess whether the 2010 EPA IUR could be scientifically substantiated. Due to clear interspecies differences in carcinogenic response to chloroprene, we applied a physiologically based pharmacokinetic model for chloroprene to calculate a species-specific internal dose (amount metabolized/gram of lung tissue) and derived an IUR that is over 100-fold lower than the 2010 EPA IUR. Therefore, we recommend that EPA's IUR be updated.  相似文献

The Sexual Inhibition/Sexual Excitation Scales (SIS/SES) assess individual propensities to become sexually aroused and to inhibit arousal. Prior analyses of men's SIS/SES data (Janssen, Vorst, Finn, & Bancroft, 2002a) yielded one excitation factor (SES) and two inhibitory factors (SIS1/Threat of Performance Failure and SIS2/Threat of Performance Consequences). The current study utilized a dataset of 2,045 undergraduates (1,067 women and 978 men) to examine the psychometric properties of women's SIS/SES scores. Women scored higher on sexual inhibition and lower on sexual excitation compared with men. The convergent/discriminant validity of women's SIS/SES scores globally resembled men's, but showed stronger associations with other sexuality - related measures and less pronounced relationships with measures of general behavioral approach/avoidance. The test-retest reliability of men's and women's SIS/SES scores were similar, but individual items exhibited differential relevance to men's and women's arousal. An exploratory factor analysis of women's scores was utilized to further examine shared and unshared themes.  相似文献

Hurricane Katrina brought to the surface serious questions about the capacity of the public health system to respond to community-wide disaster. The storm and its aftermath severed developmentally protective family and community ties; thus its consequences are expected to be particularly acute for vulnerable adolescents. Research confirms that teens are at risk for a range of negative outcomes under conditions of life stress and family disorganization. Specifically, the multiple interacting risk factors for substance abuse in adolescence may be compounded when families and communities have experienced a major trauma. Further, existing service structures and treatments for working with young disaster victims may not address their risk for co-occurring substance abuse and traumatic stress reactions because they tend to be individually or peer group focused, and fail to consider the multi-systemic aspects of disaster recovery. This article proposes an innovative family-based intervention for young disaster victims, based on an empirically supported model for adolescent substance abuse, Multidimensional Family Therapy (MDFT; Liddle, 2002). Outcomes and mechanisms of the model's effects are being investigated in a randomized clinical trial with clinically referred substance-abusing teens in a New Orleans area community impacted by Hurricane Katrina.  相似文献

Burgeoning research suggests that men engage in a variety of coercive and non-coercive tactics to avoid condom use (condom use resistance; CUR), suggesting a risk nexus regarding sexual risk and sexual aggression (SA). Laboratory-based research has found that acute alcohol intoxication is associated with CUR; however, no study has examined event-level associations among alcohol consumption, SA history, and CUR or the moderating effects of trait anger. Non-problem drinking young adult men who have sex with women (N = 430) completed a background survey and follow-up assessments regarding their sex events and alcohol consumption over three months. CUR was reported in 113 sex events; 6.2% of these involved SA and 40.7% involved alcohol consumption. Generalized estimating equations demonstrated that men with more severe SA histories were more likely to perpetrate CUR. Men lower in trait anger were more likely to perpetrate CUR the more they increased above their typical level of alcohol consumption, whereas men higher in trait anger were similarly likely to perpetrate CUR regardless of their alcohol consumption. Results suggest that men with greater SA histories and high trait anger are at increased risk of perpetrating CUR, and that risk of CUR increases among other men the more they increase their alcohol consumption beyond their average.  相似文献

Fairness is central to morality. Previous research has shown that children begin to understand fairness between the ages of four and six, depending on the context and method used. Within distributive contexts, there is little clear evidence that children have a concept of fairness before the age of five. This research, however, has mostly examined children's explicit verbal responses to questions about unequal distributions—a method that often underestimates children's knowledge. In the current study, we instead examined emotional and behavioral signs that children notice and dislike inequality. We distributed an unequal number of rewards (stickers) among pairs of children (the ages of three to five years) and probed their responses to the inequality. Both implicit and explicit measures revealed that children as young as three years old notice and react negatively to an unfair distribution, particularly when they receive less than their partner. The few age trends that were found involved verbal (explicit) responses, providing evidence that although children do not explicitly talk about fairness until the age of five or six, this talk is an effort to explain emotional reactions that emerged earlier in development.  相似文献
