Evaluators have often had trouble providing analyses that are of practical use to policymakers. A major reason for this is that evaluators characteristically pay little attention to variables that are politically relevant. The National Institute of Education's evaluation of Title I of the Elementary and Secondary Education act, used extensively by Congress in 1977–1978, provides a clear example of how attention to political concerns can pay off for evaluators in increased utilization of their products. 相似文献

Death associated with nitrite ingestion: report of a case 总被引:1,自引:0,他引:1
The tissue concentrations of nitrite and nitrate found at autopsy of a case of intentional ingestion of nitrite salts have been reported. The percentage of methemoglobin and the serum nitrite concentrations are consistent with those reported for acute overdoses. We conclude that noth nitrite and nitrate salts may be identified in tissues from persons ingesting only nitrite salts and that a significant conversion to nitrate may result from oxidation of nitrite during the conversion of heme iron to Fe3+. 相似文献

A breath-alcohol screening device, Alcolmeter pocket model, was evaluated in a controlled field trial with policeman operating the instruments. The results of tests made with subjects before they drank alcohol were always zero. The standard deviation (S.D.) of breath alcohol determinations increased with increase in the concentration of alcohol in the sample, being 0.036 mg/ml at a mean blood-ethanol concentration of 0.53 mg/ml. The S.D. varied among subjects tested (from 0.022 to 0.053 mg/ml) as well as among the instruments used (from 0.023 to 0.054 mg/ml). The breath test results were on average less than the actual blood-ethanol concentrations when a 2100: 1 blood/breath ratio was used to calibrate the Alcolmeter device. Blood ethanol (x) and Alcolmeter readings (y) were highly correlated (r = 0.95 +/- 0.018) and the regression equation was y = -0.017 + 0.95x. At a mean blood-ethanol concentration of 0.50 mg/ml, the Alcolmeter instrument will indicate 0.46 mg/ml on average. The standard error estimate was 0.085 mg/ml, being 17% of the mean Alcolmeter reading and this corresponds to 95% confidence limits of +/- 0.17 mg/ml. The results of this study show that Alcolmeter pocket-model is a useful device for breath-alcohol screening purposes at a blood-alcohol level of 0.50 mg/ml. A blood/breath ratio of 2300 should be used to calibrate the Alcolmeter device. 相似文献

This longitudinal investigation examined main and interactive effects of coparent support and conflict on mother and child adjustment in 248 low-income, African American, single mother-headed families. The findings indicated that coparent conflict was a more robust predictor of mother and child maladjustment both cross-sectionally and longitudinally than was coparent support. Moreover, findings revealed that coparent conflict and support interacted to predict one parenting behavior, monitoring, both cross-sectionally and longitudinally. Coparent relationships characterized by high levels of support and low levels of conflict were associated with the highest levels of parental monitoring behavior, whereas coparent relationships characterized by low levels of support and high levels of conflict were associated with the lowest levels of monitoring. The findings highlight the importance of examining both positive and negative aspects of coparent relationships in this at-risk, but understudied, group. 相似文献

HIV infection among the mentally ill is estimated to be at least eight times the prevalence in the general population. Psychiatric patients may also be disproportionately vulnerable to other sexually transmitted infections (STIs), but this has not been well studied. We sought to characterize the prevalence and correlates of STIs in a sample of psychiatric outpatients (N=464). Over one-third of the sample (38%) reported a lifetime history of one or more STIs. Multivariate analyses showed that, relative to those without an STI history, patients with a lifetime STI history were more knowledgeable about HIV, expressed stronger intentions to use condoms, and perceived themselves to be at greater risk for HIV. However, those with a past STI were also more likely to report sex with multiple partners and reported more frequent unprotected sex in the past 3 months. Treatment for an STI may increase HIV knowledge and risk reduction motivation, but does not necessarily lead to changes in sexual risk behavior among psychiatric patients. Findings highlight the need for STI/ HIV risk reduction interventions in psychiatric settings, particularly for patients with high-risk profiles. 相似文献

Mental health review bodies engage in complex decision-making that may explicitly incorporate a therapeutic philosophy. Examination of select decisions of the New Zealand Mental Health Review Tribunal offers a foundation for understanding some implications of a pro-therapeutic approach. This analysis draws upon therapeutic jurisprudence scholarship in relation to three aspects of the hearings as documented in the written decisions: advocacy, therapeutic intervention, and the dignitary potential of the proceedings. The research explores the unintended consequences of a pro-therapeutic approach and evaluates the potential application of therapeutic jurisprudence within a mental health law context. 相似文献

The concept of community standards is the cornerstone of advertising self‐regulation in Australia. However, there is a dearth of research on current attitudes towards advertising and a virtual absence of such data in an Australian context. A questionnaire was developed to assess consumer attitudes towards advertising; respondents were 872 adults residing in New South Wales. We found high levels of concern regarding advertising standards in general and a consistent perception that advertising should not, for example, use coarse language or violent images, portray women or men as sex objects or show nudity, stereotype or make fun of groups of people, or convey messages that undermine parental authority. In relation to specific appeals and executional elements, although we identified numerous statistically significant demographic differences, there was a clear majority view as to what elements are unacceptable. That is, rather than the posited vocal ‘moral minority’, there is a consistency of views across the community on key issues of advertising standards. The finding that only a very small proportion of community‐based respondents knew how to make a complaint to the correct organisation suggests that studies utilising complainant samples are unlikely to be representative of those who are concerned about advertising.
