Assessing the effects of changes still emerging under welfare reform and its overarching policy of devolution presents a challenge to evaluators. Given such features as time limits and benefits caps that vary widely across states and communities, it is necessary not only to attend to urgent issues of immediate relevance for individuals on public assistance but also to focus on important long-term analyses of this complex intergovernmental set of policies. The authors present a conceptual framework based on evaluation utilization and illustrate it with research questions under the rubric of welfare reform. The approach crosses three types of utilization--conceptual, instrumental, and political--with two utilization settings--policy adoption and program implementation. Evaluation strategies are linked to the utilization framework and illustrated with examples from studies of welfare reform. In the aggregate, evaluation studies represent a reasonable range of urgent and important issues across most utilization types and settings.  相似文献

Most peer group self-identification research has been conducted in the United States. This article examined the generalizability of self-identified group name research among teens in Ufa, a city in the Russian Federation. A cross-sectional, anonymous collection of data on group self-identification, drug use, addiction concern, sensation seeking, and self-rated school performance was collected from 365 10th grade youth in Ufa and 965 10th grade youth in the United States. The results supported the existence of peer group self-identification by youth in both countries and, in general, replicated the findings that youth who self-identify as a High Risk Youth, are relatively likely to use drugs, show greater concern about becoming an addict, report a greater sensation seeking preference, higher levels of depression, and poorer school performance. Implications of these results are discussed.  相似文献

Childhood sexual abuse (CSA) and adult intimate partner violence (IPV) have both been found to be associated with sexually transmitted infections (STIs) independently, but studies of STIs have rarely looked at victimization during both childhood and adulthood. This paper examines the relationship between CSA, IPV and STIs using data from a nested case-control study of 309 women recruited from multiple health care settings. Overall, 37.3% of women experienced no violence, 10.3% experienced CSA only, 27.3% experienced IPV only, and 25.0% experienced both CSA and IPV. Having ever been diagnosed with an STI was associated with violence (CSA only, odds ratios [OR] = 2.8, 95% confidence intervals [CI] = 1.0-7.5; IPV only, OR = 2.2, 95% CI = 1.0-4.9; CSA and IPV: OR = 4.0, 95% CI = 1.7-9.4), controlling for demographic characteristics. Women who experienced CSA were younger when they were first diagnosed. Understanding how both childhood and adult victimization are associated with diagnosis of STIs is important to reducing the incidence and prevalence of STIs, as well as the associated consequences of STIs.  相似文献

Under certain conditions, many multiple contrast tests based on the difference of treatment means can also be conveniently expressed in terms of ratios. In this paper, a Williams test for trend is defined as ratios-to-control for ease of interpretation and to obtain directly comparable confidence intervals. Simultaneous confidence intervals for percentages are particularly helpful for interpretations in the case of multiple endpoints. Methods for constructing simultaneous confidence intervals are discussed under both homogeneous and heterogeneous error variances. This approach is available in the R extension package mratios. The proposed method is used to test for trend in an immunotoxicity study with several endpoints as an example.  相似文献

In recent decades, the prevalence of abuse against women, older persons, and persons with disabilities has become a major public health problem. Health professionals, urged by their professional associations to universally screen these groups, have employed various tools in an effort to identify individuals in need of help. Yet many of the tools used widely in clinical settings have limitations in terms of empirical soundness. This article presents tools used to screen women, older persons, and persons with disabilities as well as data on the reliability and validity of these instruments. These properties and the resources needed to reduce harm are important factors to consider before implementing screening. The article concludes with a summary of the risk-benefit issues related to the use of these tools and universal screening in general.  相似文献

Research questionHow do women who choose not to breastfeed perceive their healthcare experience?MethodThis qualitative research study used a phenomenographic approach to explore the healthcare experience of women who do not breastfeed. Seven women were interviewed about their healthcare experience relating to their choice of feeding, approximately 4 weeks after giving birth. Six conceptions were identified and an outcome space was developed to demonstrate the relationships and meaning of the conceptions in a visual format.FindingsThere were five unmet needs identified by the participants during this study. These needs included equity, self sufficiency, support, education and the need not to feel pressured.ConclusionWomen in this study who chose not to breastfeed identified important areas where they felt that their needs were not met. In keeping with the Code of Ethics for Nurses and Midwives, the identified needs of women who do not breastfeed must be addressed in a caring, compassionate and just manner. The care and education of women who formula feed should be of the highest standard possible, even if the choice not to breastfeed is not the preferred choice of healthcare professionals.  相似文献

We draw on collective efficacy theory to extend a contextual model of early adolescent sexual behavior. Specifically, we hypothesize that neighborhood structural disadvantage--as measured by levels of concentrated poverty, residential instability, and aspects of immigrant concentration--and diminished collective efficacy have consequences for the prevalence of early adolescent multiple sexual partnering. Findings from random effects multinomial logistic regression models of the number of sexual partners among a sample of youth, age 11 to 16, from the Project on Human Development in Chicago Neighborhoods (N = 768) reveal evidence of neighborhood effects on adolescent higher-risk sexual activity. Collective efficacy is negatively associated with having two or more sexual partners versus one (but not zero versus one) sexual partner. The effect of collective efficacy is dependent upon age: The regulatory effect of collective efficacy increases for older adolescents.  相似文献

The present study investigated the relations among testosterone level, acute alcohol consumption, and the use of violent (Rough) or non-violent (Civil) conflict resolution strategies in lesbian couples. The participants were 54 lesbian campers at a women's campground or spectators at a gay pride celebration who each provided a saliva sample for testosterone assay and completed a questionnaire. On the questionnaire, participants indicated whether they used Civil or Rough tactics to deal with domestic discord, and whether or not their use of these tactics varied with their use of alcohol. High testosterone women used Rough tactics equally when drinking as when not drinking, while low testosterone women used Rough tactics far more often when drinking than when not drinking. Alcohol appears to release violent tenden- cies in low testosterone women, who are characteristically restrained under sober conditions, but has little effect on high testosterone women.  相似文献
