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

Researchers have worked to refine the measurement of women's experiences with sexual victimization. Less is known about the validity and reliability of measures that assess men's use of sexual coercion and aggression. These studies explore the consistency of men's responses to two distinct, but similar, measures of sexual coercion and aggression. The two measures both assess historical use of verbal coercion, sexual assault involving drugs or alcohol, and sexual assault through threat or force. Study 1 used college men as participants (N = 398), whereas Study 2 used a mixed sample of college and community men (N = 184). In both studies, participants’ responses were largely inconsistent across the two measures. This article explores potential measurement issues that may account for the observed reporting discrepancies and offers suggestions for future research.  相似文献

In the early stages of the recent recession, men were disproportionately among the ranks of the unemployed. Current economic times provide a researchable moment, as more women are likely to be in positions of power vis-à-vis earnings. This article uses a unique nationally representative dataset of married individuals (n = 158) to examine expected level of support for relocation if the respondent's spouse were offered a hypothetical job opportunity. Although there do appear to be gender differences in the associations between background characteristics and expected level of support, we find no basis for our hypotheses about the nature of the relationships between race, class, and expected level of support. Black women have higher levels of expected support than do White women, whereas Black men have lower levels of expected support than do White men; there are no class differences in expected level of support. We interpret these findings in the context of the complicated performance of gender in challenging economic times.  相似文献

The present research examines the performance consequences of the influence of four major departments (sales, marketing, R&D, and manufacturing) and integrates organizational life cycle stages as moderating variables. Further, the article derives a hypothesis that addresses the influence dispersion among the departments that is most beneficial for performance. In order to validate this research model empirically, survey data from small and medium-sized German firms were gathered. Findings show that the optimal distribution of influence among departments is a function of the organizational life-cycle stage. While no moderating effects of the life-cycle stage emerge for the sales or manufacturing departments, a strong marketing department contributes to organizational performance only in early stages, while a strong R&D department contributes only in later stages. Further, the estimation of the non-linear regression model shows that a medium level of influence dispersion among departments is most beneficial to organizational performance.  相似文献

BackgroundThere are many providers and models of prenatal care, some more effective than others. However, quantitative research alone cannot determine the reasons beneficial models of care improve health outcomes. Perspectives of women receiving care from effective clinics can provide valuable insight.MethodsWe surveyed 29 women receiving care at a rural, Appalachian birth center in the United States with low rates of preterm birth. Semi-structured interviews and demographic questionnaires were analyzed using conventional qualitative content analysis of manifest content.FindingsInsurance was the most common facilitator of prenatal access. Beneficial characteristics of the provider and clinic included: personalized care, unrushed visits, varied appointment times, short waits, and choice in the type and location of care.ConclusionThere is a connection between compassionate and personalized care and positive birth outcomes. Women were willing to overcome barriers to access care that met their needs. To facilitate access to prenatal care and decrease health disparities, healthcare planners, and policy makers need to ensure all women can afford to access prenatal care and allow women a choice in their care provider. Clinic administrators should create a welcoming clinic environment with minimal wait time. Unrushed, woman-centered prenatal visits can increase access to and motivation for care and are easily integrated into prenatal care with minimal cost.  相似文献

In this paper, Anbar's (1983) approach for estimating a difference between two binomial proportions is discussed with respect to a hypothesis testing problem. Such an approach results in two possible testing strategies. While the results of the tests are expected to agree for a large sample size when two proportions are equal, the tests are shown to perform quite differently in terms of their probabilities of a Type I error for selected sample sizes. Moreover, the tests can lead to different conclusions, which is illustrated via a simple example; and the probability of such cases can be relatively large. In an attempt to improve the tests while preserving their relative simplicity feature, a modified test is proposed. The performance of this test and a conventional test based on normal approximation is assessed. It is shown that the modified Anbar's test better controls the probability of a Type I error for moderate sample sizes.  相似文献

Implementation fidelity in a teacher-led alcohol use prevention curriculum   总被引:2,自引:0,他引:2  
There is now ample evidence that teachers tend to make substantial modifications to both the prescribed content and methods of the curricula they administer, and that such modifications are likely to attenuate curricula effects. We examine the fidelity with which teachers implement "Protecting You, Protecting Me," an underage alcohol use prevention curriculum. Findings suggest that while teachers attempted to implement most sections of a lesson, the lessons taught were consistently--and often extensively--adapted. We conclude that since teachers are likely to continue to modify lessons, curriculum developers and trainers should enhance their understanding of how prevention curricula are taught under real world conditions, help teachers to reinforce key curriculum concepts, and consider modifying those curricular sections that teachers are adapting with greatest frequency.  相似文献

This article assesses whether there are methodological problems with child outcome measures that may contribute to the small associations between child care quality and child outcomes found in the literature. Outcome measures used in 65 studies of child care quality published between 1979 and December 2005 were examined, taking the previous review by Vandell and Wolfe (2000) as the starting point. Serious methodological problems were not pervasive for child outcome measures. However, methodological concerns were most prevalent among measures of socioemotional development. Furthermore, psychometric information on outcome measures was often missing from published reports, and health outcomes and approaches to learning were infrequently studied. Future research should address alignment issues between aspects of quality and the specific child outcomes chosen for study.  相似文献

Although parent ratings, adolescent ratings, and observations are all utilized to measure parent emotion socialization during adolescence, there is a lack of research examining measurement differences and concordance. Thus, the present study compared three measures of parent supportive and nonsupportive emotion socialization and examined whether parent and adolescent emotion dysregulation differentially related to these measures or moderated concordance across measures. Participants were a community sample of 92 adolescent-parent dyads. Adolescents were 13–17 years-old (M = 15.5, SD = 1.1), 41 were female and 51 were male; 87% of parents identified as mothers. Observed emotion socialization was coded during a parent-adolescent conflict discussion task. The adolescent and parent also rated the parent's supportive and nonsupportive reactions to the adolescent's negative emotions; they each also rated their own emotion dysregulation. Due to data collection timing, COVID-19 family stress was also assessed and explored as a covariate in analyses. Bivariate correlations indicated that there were weak and non-significant correlations across emotion socialization measures. Multilevel models indicated that measures of parent emotion socialization were differentially associated with adolescent emotion dysregulation, with adolescent emotion dysregulation relating significantly to adolescent ratings, but not observations or parent ratings, of parent emotion socialization. In addition, multiple regressions indicated that there was less concordance across measures when parents were higher in emotion dysregulation. Results suggest that measurement may influence researchers’ conclusions about how youth adjustment relates to parent emotion socialization. Additionally, there may be even lower agreement across measures of parent emotion socialization when parents have emotional challenges.  相似文献
