Latinas in the United States are at a disproportionate risk for STDs and sexual risk behaviors. Among Latinas, acculturation
has been found to be one of the most important predictors of these behaviors. Therefore, this study examined the longitudinal
association between Latina adolescents’ level of acculturation and multiple sexual risk outcomes, including self-report STD
diagnosis, four or more life-time sex partners, regret of sexual initiation after alcohol use, and lack of condom use during
young adulthood. Based on the National Longitudinal Study of Adolescent Health (Add Health), this study includes a nationally
representative sample of 1,073 Latina adolescents (ages 11–20 at Wave 1) transitioning into young adulthood (ages 18–27 at
Wave 3). Our findings indicate that more acculturated Latinas who spoke English at home were more likely to have STDs and
to exhibit sexual risk behaviors than Latinas who were foreign-born and did not use English at home. Interventions that aim
to promote sexual and reproductive health among young Latinas should take into consideration their different levels of acculturation.
This approach holds greater potential for reducing health disparities among Latinas. 相似文献

The purpose of this study was to investigate how different types of child maltreatment, independently and collectively, impact
a wide range of risk behaviors that fall into three domains: sexual risk behaviors, delinquency, and suicidality. Cumulative
classification and Expanded Hierarchical Type (EHT) classification approaches were used to categorize various types of maltreatment.
Data were derived from Wave III of the National Longitudinal Study of Adolescent Health (Add Health). Our sample consisted
of White, Black, Hispanic, and Asian females ages 18 to 27 (n = 7,576). Experiencing different kinds of maltreatment during childhood led to an extensive range of risk behaviors within
the three identified domains. Women experiencing sexual abuse plus other maltreatment types had the poorest outcomes in all
three domains. These findings illustrate that it may no longer be appropriate to assume that all types of maltreatment are
equivalent in their potential contribution to negative developmental sequelae. 相似文献

There is growing interest in the application of citizen participation within all areas of public sector service development, where it is increasingly promoted as a significant strand of post-neoliberal policy concerned with re-imagining citizenship and more participatory forms of citizen/consumer engagement. The application of such a perspective within health services, via co-production, has both beneficial, but also problematic implications for the organisation of such services, for professional practice and education. Given the disappointing results in increasing consumer involvement in health services via 'choice' and 'voice' participation strategies, the question of how the more challenging approach of co-production will fare needs to be addressed. The article discusses the possibilities and challenges of system-wide co-production for health. It identifies the discourse and practice contours of co-production, differentiating co-production from other health consumer-led approaches. Finally, it identifies issues critically related to the successful implementation of co-production where additional theorisation and research are required. 相似文献

The entry and exit of ministers has been of primary interest to students of political science and public management in Western countries. Responding to the lack of research on the entry and exit of ministers in non‐Western countries, this article examined determinants of both the entrance and exit of ministers in Korea from the life cycle point of view based on the Korean Ministerial Database from 1980 to 2008. We argued that as the Korean presidency shifts from an imperialistic to a democratic presidency, ministerial appointments in Korea also seem to shift from an expertise‐focused to a politics‐focused approach. Likewise, the primary resignation reason also shifts from policy failure to political reasons. We also argued that Korean presidents use their power to reshuffle cabinet ministers too often for their political interests. As a result, Korean ministers spend too little time in post; average tenure is now down to about one year. These short terms in office dilute a minister's ability to dictate departmental policy. 相似文献

ABSTRACT The study of the length of ministerial tenure has received some attention by scholars of public management in Western countries. Responding to the lack of empirical research on ministerial duration in non-Western countries, this article empirically examines the determinants of ministerial duration based on the Korean Ministerial Database from 1980 to 2008. The empirical findings are as follows. First, being a female minister decreases the probability of stepping down by 1.78 times compared to a male minister. Second, political democratization after 1987 drastically increases the probability of ministerial stepping down by 3.46 times. Third, confirmation hearings after 2005 decrease the probability of ministerial stepping down by 0.53 times. Based on these empirical findings of the analysis, we can identify distinctive characteristics of ministerial duration in Korea. We argue that as the Korean political system shifts from military or authoritarian rule to democratic rule after 1987, a single five-year presidential term may set a political environment for frequent changes of ministers to allocate political spoils. 相似文献

The following article traces the development of East Germany's secret police, the Stasi, during the reign of Ernst Wollweber, the second Minister of State Security. By examining key Stasi operations during this period, notably the ‘concentrated strikes’ strategy following the June 1953 revolution, the campaign against Ostbüros, and operations to secure the economy, and by examining Wollweber's major speeches, it argues that Wollweber's reign was a decisive one for the Stasi because of the integration of intelligence gathering outside of East Germany (Aufklärung) with domestic surveillance (Abwehr). Although this balance shifted toward external duties in Wollweber's landmark August 1955 speech, Wollweber continued to promote integration of the two duties, in particular by anchoring the intelligence gathering duties in the local-level domestic structures of the Stasi. 相似文献

We investigate the role of payoff asymmetry in laboratory prisoner’s dilemma games. Symmetric and asymmetric games are examined in simultaneous and sequential settings. In the asymmetric sequential games, we study the impact of having payoff advantaged players moving either first or second. Asymmetry reduces the rates of cooperation in simultaneous games. In sequential games, asymmetry interacts with order of play such that the rate of cooperation is highest when payoff disadvantaged players move first. 相似文献

The construction of public problems has a lasting influence on implementation in a given policy subsystem. National and sociopolitical contexts influence issue definition differently across nations. However, the degree to which nation-specific issue definition takes place has been insufficiently explored. In recent years, the growing incidence of autism has led to a quest for causal factors. One hypothesis posits that the use of mercury in vaccines may be a culprit. This paper examines the definition of the mercury and autism issue in Australia, Canada, the United Kingdom, and the United States. Insights into the comparative elements of issue definition are suggested by the case. These insights are of particular importance to administrators, as agencies are deeply involved as objects and actors in the process of issue definition and are often responsible for implementing new and redefined policies. 相似文献
