Abstract

Objective: To examine the prevalence of drug-related sexual assaults, identify the frequency of assaults that occur following voluntary versus involuntary drug or alcohol consumption, and identify contextual correlates of drug-related assaults. Participants: College-student females (n = 314). Methods: Volunteers reported experiences with forcible and drug-related sexual assaults in the spring semester of 2004. Follow-up queries regarding the most severe drug-related assaults determined whether the assaults followed voluntary or involuntary alcohol or drug consumption. Results: 29.6% (n = 93) of the respondents reported a drug-related sexual assault or rape; 5.4% (n = 17) reported a forcible sexual assault or rape. Voluntary incapacitation preceded 84.6% of drug-related assaults and involuntary incapacitation preceded 15.4% of drug-related assaults. The majority of drug-related assaults (96.1%) involved alcohol consumption prior to assault. Conclusions: Drug-related sexual assaults on college campuses are more frequent than are forcible assaults and are most frequently preceded by voluntary alcohol consumption.  相似文献

The development of preventive interventions targeting adolescent problem behaviors requires a thorough understanding of risk and protective factors for such behaviors. However, few studies examine whether different cultural and ethnic groups share these factors. This study is an attempt to fill a gap in research by examining similarities and differences in risk factors across racial and ethnic groups. The social development model has shown promise in organizing predictors of problem behaviors. This article investigates whether a version of that model can be generalized to youth in different racial and ethnic groups (N=2,055, age range from 11 to 15), including African American (n=478), Asian Pacific Islander (API) American (n=491), multiracial (n=442), and European American (n=644) youth. The results demonstrate that common risk factors can be applied to adolescents, regardless of their race and ethnicity. The findings also demonstrate that there are racial and ethnic differences in the magnitudes of relationships among factors that affect problem behaviors. Further study is warranted to develop a better understanding of these differential magnitudes.  相似文献

Abstract

Objective: This study examines the prevalence and risk factors associated with risky sexual behaviors in community college students. Participants: A diverse sample of 18–19-year-old community college students (N?=?264). Methods: Baseline data from an online prevention program administered in 2015. Results: Community college students in this sample disproportionately experienced sexual assault and were unlikely to test for STIs. Higher intentions to engage in risky sexual behaviors were associated with gender and sexual experience, but also with having lower intentions to communicate with a sexual partner about pregnancy and STIs, and having higher gender norm endorsement. Conclusions: Older adolescents attending community colleges may be at high risk for poor sexual health outcomes, and appropriate theory-based education should be tailored to meet the needs of these underserved students.  相似文献

This investigation focused on the friendship concepts of pre‐school‐aged children. Eighty‐four 3‐ to 5‐year‐old children responded to questions about social provisions, or benefits of relationships, available from reciprocal friends (both children in a pair nominate each other as friends), unilateral friends (one child nominates the other), non‐friends (neither child of a pair nominates the other), and imaginary friends (for those who had them). Results indicated that reciprocal and imaginary friends were the best sources of social provisions, followed by unilateral friends and non‐friends. Major implications are that children draw distinctions between reciprocal and unilateral friends based on the levels of social provisions available in these relationships, and that relationship schemas underlying relationships with imaginary companions may be akin to those for reciprocal friends. Children's friendship schemata may also differ by gender, as girls discriminated more than boys between reciprocal and unilateral friends for the social provision of companionship.  相似文献

Caregiving is a process of transformed identities and reconstructed relations. The disruption of Alzheimer's disease affects both the individual with dementia and the person providing care. One becomes enselfed in dementia, the other transformed into a caregiver. Using data from twenty qualitative interviews with family caregivers, this article traces the transformative process by which the previous relational selves of both participants become casualties of the disease. Findings suggest that the ill person in this dyad is silenced through dementia, leaving the caregiver narratives to become the morality tales of transformation from disorder to order, from havoc to meaningful interaction. By becoming caregivers, family members construct value in their struggles to negotiate the disorder of illness and recreate meaningful and affirming selves and relationships.  相似文献

The product method of estimation (Murthy, 1964) complements the ratio method when the study variate, y, and an auxiliary variate, x, have negative correlation. However, such cases are not frequent in survey practice. This paper suggests a simple transformation of x in the more common situation of positive correlation between y and x, to permit a product method of estimation rather than a ratio method. This leads to the advantage that the bias and mean square error have exact expressions. The technique developed by Quenouille (1956) and applied by Shukla (1976) is used for making the estimator unbiased. The minimum variance situation is investigated. Two numerical examples are included. The case of negative correlation is also examined.  相似文献

Although conflict is central to major developmental theories, relatively little is known about the ways in which young children and caregivers argue at home. The existing psychological research focuses narrowly on serious, ‘problem-solving’ conflicts. In contrast, this in-depth longitudinal study describes varieties of spontaneous conflict talk occurring at home between nine middle-class Caucasian American mothers and their 2- to 4-year-old children. All dyads produced conflicts with nonse-rious, imaginary and/or ritual markings for a mean of 31% (± 2.8%) of all mother-child conflicts. Overall, most mother-child marked conflicts were nonserious, but the percentage of marked conflicts that were imaginary increased with age. Mothers used marked conflicts to manage ongoing problematic interactions with their children, while children apparently introduced marked conflicts primarily during play. Available data on child-child conflicts showed that some of these conflicts also were marked and were introduced primarily during play. Implications for how varieties of conflict may contribute to social competence within the family and peer group are discussed.  相似文献

Background

In February 2009 the Improving Maternity Services in Australia – The Report of the Maternity Services Review (MSR) was released, with the personal stories of women making up 407 of the more than 900 submissions received. A significant proportion (53%) of the women were said to have had personal experience with homebirth. Little information is provided on what was said about homebirth in these submissions and the decision by the MSR not to include homebirth in the funding and insurance reforms being proposed is at odds with the apparent demand for this option of care.

Method

Data for this study comprised 832 submissions to the MSR that are publicly available on the Commonwealth of Australia Department of Health and Aging website. All 832 submissions were downloaded, coded and then entered into NVivo. Content analysis was used to analyse the data that related to homebirth.

Findings

450 of the submissions were from consumers of maternity services (54%). Four hundred and seventy (60%) of the submissions mentioned homebirth. Overall there were 715 references to home birth in the submissions. The submissions mentioning homebirth most commonly discussed the ‘Benefits’ and ‘Barriers’ in accessing this option of care. Benefits to the baby, mother and family were described, along with the benefits obtained from having a midwife at the birth, receiving continuity of care and having a good birth experience. Barriers were described as not having access to a midwife, no funding, no insurance and lack of clinical privileging for midwives.

Conclusion

Many positive recommendations have come from the MSR, however the decision to exclude homebirth from these reforms is perplexing considering the large number of submissions describing the benefits of and barriers to homebirth in Australia. A concerning number of submissions discuss having had or having considered an unattended birth at home due to these barriers. Overall there is the belief that not enabling access to funded, insured homebirth in Australia is a violation of human rights. It appears that homebirth was considered by the MSR as ‘too hot to handle’ and by dismissing it as a minority issue the government sought to avoided dealing with homebirth as a ‘sensitive and controversial issue.’  相似文献
