Early puberty is associated with stressful family environments, early sexual intercourse, and teenage pregnancy. We examined pubertal timing and sexual debut among the 14-year-old offspring of teenage mothers. Mothers (71% Black, 29% White) were recruited as pregnant teenagers (12–18 years old). Data were collected during pregnancy and when offspring were 6, 10 and 14 years old (n = 318). Adolescents (50% male) compared the timing of their pubertal maturation to same-sex peers. There was a significant 3-way interaction effect of race, sex, and pubertal timing on sexual debut (n = 305). This effect remained significant in a model controlling for maternal age at first intercourse, substance use, exposure to trauma, authoritative parenting, and peer sexual activity (n = 255). Early maturation was associated with early sex in daughters, and may be one pathway for the inter-generational transfer of risk for teenage pregnancy among daughters of teenage mothers.  相似文献

We investigated agency directors' perspectives about how service goals should be prioritized for domestic violence and sexual assault service subtypes, including crisis, legal advocacy, medical advocacy, counseling, support group, and shelter services. A sample of 97 (94% response rate) North Carolina domestic violence and/or sexual assault agency directors completed a survey asking participants to rank the importance of service goals. Overall, participants considered emotional support provision to be a critical service goal priority across all service types. Social support and self-care service strategies were deemed less important. However, prioritization of other service goals varied depending on the service type. Statistically significant differences on service goal prioritization based on key agency characteristics were also examined, and agency characteristics were found to relate to differences in service goal prioritization.  相似文献

Trading places     
This paper examines effects that alternative voting systems can have on electoral outcomes in multicandidate elections. Using ballots collected from a county Republican Party special election, we recount the votes using preference-based voting systems and compare the results to the special election outcome. Relative rankings of candidates change across vote counting rules and voting systems. Because candidates trade places depending on rules, there are strong strategic implications for candidates and for those establishing the rules.  相似文献

Women are the fastest growing segment of the criminal justice population, yet the majority of research on criminal justice populations has been focused on men. Programming and interventions that reduce women’s involvement in the criminal justice system and ameliorate the negative consequences associated with criminal justice involvement are urgently needed. The overall aim of this paper is to provide a comprehensive framework for developing evidence-based, gender-specific programming and interventions to reduce criminal justice involvement and its associated consequences among women in the criminal justice system. The first section of the paper offers a conceptually guided review of the three primary factors that facilitate and complicate women’s involvement in the criminal justice system: victimization; mental disorders; and substance use. In the second section of the paper, findings from focus groups conducted with women on probation or parole identify strategies to engage this population in psychosocial interventions. The third and final section of the paper provides comprehensive recommendations for designing programming and interventions for women in the criminal justice system.  相似文献

In 1998, Congress passed the first law protecting the privacy of individuals on the Internet. The Children's Online Privacy Protection Act (COPPA) restricts the online collection of personal information from children aged 12 or younger. Under the law, Web sites that maintain chat rooms directed at children must either condition a child's participation on the consent of a parent or guardian or monitor the chat room and censor references to personal information. This article examines whether COPPA's chat room restrictions infringe on the free speech rights of children. The examination finds that aspects of the chat room restrictions are constitutionally suspect because it is questionable whether the parental consent requirement is narrowly tailored.  相似文献

Abstract

Rising high above the lush Cambodian jungle, the spiraled gray towers of Angkor Wat mark the cosmological center of one of the most brillant ancient civilizations of Southeast Asia. Today, all that remains of this vast Khmer kingdom is a nation about the size of Washington state, a nation inhabited by nearly seven million people; most of whom spend their lives in the verdant paddy fields surrounding their village. Although proud of their heritage, they do not aspire to new glories of conquest and empire. Rather the Cambodians have long sought one-thing: peace.  相似文献

A major barrier to the quantitative investigation of interactions between economic and non‐economic influences in economic development is the lack of adequate indicators of institutional traits of nations. Our purpose in this paper is to consider the methodological procedures involved in the development of qualitative sociopolitical and economic indicators.

The first sections of the paper deal with various aspects related to the subject of measurement. This is necessary because misconceptions regarding the nature of ‘qualitative measurement’ are common, and misleading contrasts between qualitative and quantitative measurement are frequently made. The last four sections illustrate the procedures for the measurement of institutional indicators by applying them to the quantification of the concept of political participation in developing countries.  相似文献
