The findings of this study are mixed. In general, after one year of judicial-citizen review, there is no clear indication that this alternative to internal case review has led to more positive outcomes for children in foster care. This finding should be heartening to public child welfare agency personnel whose motivation for accountability has been called into question by proponents of external foster care review. At least when compared with a new citizen review system, the already existing internal review system measured up quite well. Although the study did not indicate a clear pattern of more positive outcomes for the study group, there is evidence of some favorable characteristics of CRPs that may show promise for the future. With additional training in developing behaviorally measurable and time-limited parental objectives, citizen panels may be able to maintain some of their initial strength in this area. Increased involvement of juvenile court judges in cases where little or no progress is made could motivate some parents to meet specified objectives and speed up the process of terminating parental rights when no progress has been demonstrated within specified time periods. The data also indicate a need for some adjustment to the process used to involve parents in case reviews. Another potentially positive outcome was highlighted during interviews with the juvenile court judges and the DFCS staff in the three study counties. Many of these respondents believed that the process had the potential for moving children out of foster care more quickly than does the internal review process. In addition to this primary goal, however, respondents were excited about the potential for heightened community awareness and education as citizens come to understand more about the plight of foster children and family conditions that can lead to placement. Interviews with panel members themselves indicated a definite belief that the community needed to accept more responsibility for children in foster care. One panel member's comment reflects the general sentiment expressed by other respondents: "These are kids we used to call 'those kids,' but now they are 'our kids'." It is hoped that the judicial-citizen review process will help to create a community environment in which needed resources can be developed both to prevent placement and to provide more support for families and children when placement occurs. This is the sentiment of the three juvenile court judges and almost all DFCS staff members who were interviewed, when they asserted that they felt the CRP process should be continued and expanded statewide.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

This article aims to explore the ways in which preadolescents associate smoking with transitions to adulthood, in the context of sociological theories of childhood, using data from the Liverpool Longitudinal Study of Smoking. The research found that at age 9 many of the cohort argued that smoking was more acceptable for adults because they had bigger bodies than children. Some children also suggested that smoking was appropriate for adults because adults were competent to make important decisions and to balance risks. By age 11, when several of the cohort had actually tried smoking, children's views about the risks smoking posed to their bodies had altered, and many children were aware of smoking‐related disease among adults. The cohort also suggested that some children might take up smoking to demonstrate that they are ‘grown up’ too. In the UK, legal restrictions on the age of tobacco purchase are reinforced by social norms that construct smoking as an activity that is only suitable for adults. The goal of legal restrictions that ban the sale of cigarettes to children is to protect their health. The unintended outcome, however, is that for many young people smoking is a way of demonstrating maturity and adult status.  相似文献

A major survey of the determinants of access to primary education in Madagascar was carried out in 1994. The probability of enrolment, probability of admission, delay before beginning school, probability of repeating a year and probability of dropping out were studied. The results of the survey are briefly described. In the analysis, one major problem was non-random missing values in the covariates. Some simple methods were developed for detecting whether a response variable depends on the missingness of a given covariate and whether eliminating the missing values would distort the resulting model. A way of incorporating covariates with randomly missing values was used such that the individuals having the missing values did not need to be eliminated. These methods are described and examples are given on how they were applied for one of the key covariates that had a large number of non-random missing values and for one for which the values appear to be randomly missing.  相似文献

This study analyzes subsidy schemes that are widely used in reducing waiting times for public healthcare service. We assume that public healthcare service has no user fee but an observable delay, while private healthcare service has a fee but no delay. Patients in the public system are given a subsidy s to use private service if their waiting times exceed a pre‐determined threshold t. We call these subsidy schemes (st) policies. As two extreme cases, the (st) policy is called an unconditional subsidy scheme if t = 0, and a full subsidy scheme if s is equal to the private service fee. There is a fixed budget constraint so that a scheme with larger s has a larger t. We assess policies using two criteria: total patient cost and serviceability (i.e., the probability of meeting a waiting time target for public service). We prove analytically that, if patients are equally sensitive to delay, a scheme with a smaller subsidy outperforms one with a larger subsidy on both criteria. Thus, the unconditional scheme dominates all other policies. Using empirically derived parameter values from the Hong Kong Cataract Surgery Program, we then compare policies numerically when patients differ in delay sensitivity. Total patient cost is now unimodal in subsidy amount: the unconditional scheme still yields the lowest total patient cost, but the full subsidy scheme can outperform some intermediate policies. Serviceability is unimodal too, and the full subsidy scheme can outperform the unconditional scheme in serviceability when the waiting time target is long.  相似文献

The Caribbean Basin Economic Recovery Act eliminates U.S. tariffs on many exports of countries in the Caribbean Sea and Central America. This paper estimates the short-run effects of these tariff eliminations on the export earnings and economic welfare of the beneficiary countries. It is found that the tariff eliminations increase annual export earnings of beneficiaries by at most $81 million and provide annual welfare gains to these countries of $15 million to $24 million. The benefits are concentrated in agricultural products (particularly sugar, beef, and tobacco) and in products assembled from U.S. components for export to the United States (particularly electronic equipment). The countries that benefit most are the Dominican Republic, Panama, and Guatemala.  相似文献

Using an experimental design, we investigated the impact of participation in trauma-related research on well-being in a sample of 219 higher education students. We created five conditions that exposed participants to questions about life events. A sixth condition represented a control condition. Exposure conditions varied according to whether they contained yes/no questions about events that entailed stress, stigma, trauma, or sexual violation. We operationalized well-being by measuring positive and negative affect, state anxiety, and positive reactions to research. Across exposure conditions, participants reported low levels of negative affect and generally positive reactions immediately after participation. The most negative and least positive responses followed exposure conditions that contained questions about stressful events and sexual violation. We discuss implications of our findings for ethics review board practices.  相似文献

Alcohol consumption and related problems are common among underage college students, yet qualitative, in-depth information on how/where these students obtain alcohol is limited. We conducted focus groups pertaining to access to alcohol and related issues with 19 underage college students. They reported that alcohol is easy to obtain from a variety of sources, with friends/acquaintances who are of legal age or those with a false ID being the most common. Parties were also common sources, but "shoulder tapping" (i.e., asking a stranger to purchase alcohol) was not common. Disagreement arose over whether underage fraternity/sorority members have greater access to alcohol than non-Greeks. Our results provide updated information on the various sources of alcohol and associated issues among underage college students.  相似文献

Objectives. The primary goal of this article is to examine factors associated with grandparent care giving within the American Indian/Alaska Native (AIAN) population. Methods. Data from the 2000 Census of Population, 5% Public Use Microdata Sample, are used to evaluate a multivariate logistic regression model focusing on living with and caring for grandchildren. Particular emphasis is placed on characteristics that may reflect culturally‐based ideas about grandparents' responsibility for the care of their grandchildren. Results. Indicators related to Native‐American identity—specifically, reporting race as AIAN only rather than mixed race, reporting tribal membership, and living in a nonmetropolitan area of an “Indian” state—increase the likelihood of being responsible for a grandchild among Native‐American singles and couples aged 45 and over. Conclusions. Cultural and resource characteristics combine to produce high levels of grandparent care giving within the AIAN population. Inasmuch as those with lower educational and economic resources are especially likely to have responsibility for a grandchild, special attention should be directed toward ensuring adequate support for these caregivers.  相似文献

Per- and poly-fluoroalkyl substances (PFAS) are ubiquitous in the environment and are detected in wildlife and humans. With respect to human exposure, studies have shown that ingestion is the primary route of exposure; however, in certain settings, exposure via inhalation could also be a significant source of exposure. While many studies examined toxicity of PFAS via ingestion, limited information is available for PFAS toxicity via the inhalation route, translating into a lack of exposure guidelines. Consequently, this article examined whether route-to-route extrapolation to derive guidelines for inhalation exposure is appropriate for PFAS. Perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) were used as exemplary PFAS given the abundance of toxicity data for these two compounds. Our evaluation determined that available toxicity and toxicokinetic data support route-to-route extrapolation for PFAS in order to derive inhalation-based standards. Results from this analysis suggest that an air concentration of 7.0 × 10−5 mg/m3 (or 0.07 μg/m3) would be an appropriate RfC for PFOA and PFOS assuming the 2016 EPA RfD of 0.00002 mg/kg-day, whereas use of the interim RfDs proposed in 2022 of 1.5 × 10−9 and 7.9 × 10−9 mg/kg would yield much lower RfCs of 5.25 × 10−9 and 2.77 × 10−8 mg/m3 (or 5.25 × 10−6 and 2.77 × 10−5 μg/m3) for PFOA and PFOS, respectively.  相似文献
