In the 1990s methamphetamine (meth) emerged as a significant drug problem in the United States. Along with more widespread meth use was a growing pattern of localized production of the drug in small-scale clandestine laboratories, creating public health issues beyond the drug’s direct harms to the health of users. Early efforts in analyzing aggregate patterns of meth lab production across communities suggest this phenomenon is different from other types of crime and drug problems, showing distinctive geographic patterns and different causal/etiological dynamics. This paper assesses the viability of public health outcomes as predictors of methamphetamine laboratory problems and compares them with traditional criminological predictors as explanations for aggregate patterns in meth lab problems across U.S. counties. It documents how local variations in meth production are different from other types of crime patterns and identifies whether geographic variations in local meth labs might be more effectively predicted and explained in public health terms.  相似文献

Recent attention to best practices has resulted in a complex array of terminology and a number of compendia of effective practices that may be daunting to public policy makers and administrators seeking solutions to important public problems. This study clarifies these distinctions and builds on them to create a decision tool that will help policy makers as they use best practice information in program adoption or development. Decision makers must know their goals in seeking out best practices. As they evaluate potential practices, they should consider not only the quality of available evidence of effectiveness but also the risk of harm to constituents and the cost per unit of benefit generated. The study applies the rubric to an emerging practice in support services for individuals with disabilities known as Cash and Counseling, demonstrating that the practice is low risk, cost neutral, and improves effectiveness and consumer satisfaction. The tool highlights the judgmental elements of concern in the decision process while providing a means to assess multiple decision dimensions in a coherent fashion.  相似文献

Although the profession of public affairs (PA) is increasingly important for organizations, relatively little is known about the range of competences PA professionals need. This article presents a qualitative study among 41 experienced Dutch PA professionals and practitioners, who were interviewed about the competences needed in regional and local PA. The results show that a combination of skills‐related, attitudinal, and knowledge‐related competences is needed. Skills‐related competences involve two broad domains: politics and communication. Attitudinal competences comprise the almost paradoxical qualities of authentic professionalism and flexibility. Knowledge‐related competences comprise political and communicative knowledge. These competences are used in a delicate process of swapping, depending on the situation of the very moment and the PA file at hand. Every competence may be of decisive importance. The PA professional is a silent diplomat.  相似文献

There is an unprecedented and pressing need for a major legislative public financial management reform in Somalia to bolster the technical and professional efforts of implementing a modern system of public financial management across the country. Currently, there is no independent auditing authority to enable citizens to access information on the use of public resources. However, the success of any reform depends on establishing strong public budgeting systems as well as developing strong public finance training programs and policy linkage on financial management policies and procedures.  相似文献

Sexual minority youth (youth who are attracted to the same sex or endorse a gay/lesbian/bisexual identity) report significantly higher rates of depression and suicidality than heterosexual youth. The minority stress hypothesis contends that the stigma and discrimination experienced by sexual minority youth create a hostile social environment that can lead to chronic stress and mental health problems. The present study used longitudinal mediation models to directly test sexual minority-specific victimization as a potential explanatory mechanism of the mental health disparities of sexual minority youth. One hundred ninety-seven adolescents (14–19 years old; 70 % female; 29 % sexual minority) completed measures of sexual minority-specific victimization, depressive symptoms, and suicidality at two time points 6 months apart. Compared to heterosexual youth, sexual minority youth reported higher levels of sexual minority-specific victimization, depressive symptoms, and suicidality. Sexual minority-specific victimization significantly mediated the effect of sexual minority status on depressive symptoms and suicidality. The results support the minority stress hypothesis that targeted harassment and victimization are partly responsible for the higher levels of depressive symptoms and suicidality found in sexual minority youth. This research lends support to public policy initiatives that reduce bullying and hate crimes because reducing victimization can have a significant impact on the health and well-being of sexual minority youth.  相似文献

Sexual minority youth report higher rates of depression and suicidality than do heterosexual youth. Little is known, however, about whether these disparities continue as youth transition into young adulthood. The primary goals of this study were to describe and compare trajectories of adolescent depressive symptoms and suicidality among sexual minority and heterosexual youth, examine differences in depressive symptoms and suicidality trajectories across sexual orientation subgroups, and determine whether there are gender differences in these longitudinal disparities. Four waves of data from the National Longitudinal Study of Adolescent Health were analyzed using latent curve modeling (N = 12,379; 53 % female). Results showed that the rates of depressive symptoms and suicidality in early adolescence were higher among sexual minority youth than among heterosexual youth, and that these disparities persisted over time as participants transitioned into young adulthood. Consistent with previous cross-sectional studies, the observed longitudinal disparities were largest for females and for bisexually-identified youth. Sexual minority youth may benefit from childhood and early adolescent prevention and intervention programs.  相似文献

This article examines perceptions of motherhood as they developed during the late 1940s in the midst of the national struggle for independence in Eretz Israel (Palestine). It considers two case studies in which mothers who were ‘recruited’ by the emerging nation were temporarily separated from their children. The first case concerns women emissaries (Shelihot) who were called to help in Jewish refugee camps in Europe after the Holocaust. The second case involves mothers who were not evacuated with their children from their settlements during the War of Independence but remained, instead, at the front line. These situations led to the development of new perceptions of women and motherhood, which were shaped and matured during the national struggle for independence. The two case studies are used as lenses to explore women's own experiences and perceptions against the backdrop of the intensified idealization of motherhood in times of emergency circumstances.  相似文献
