Can evaluations influence programs? The case of compensatory education

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.     

Death associated with nitrite ingestion: report of a case

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+.     

Evaluation of breath-alcohol instruments. III. Controlled field trial with Alcolmeter pocket model

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.     

Coparent Support and Conflict in African American Single Mother-Headed Families: Associations With Maternal and Child Psychosocial Functioning

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.     

What do Australian consumers think about current advertising standards?

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.

Geophysical Monitoring of Simulated Clandestine Graves Using Electrical and Ground‐Penetrating Radar Methods: 0–3 Years After Burial*,†

Abstract: This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated “wrapped” and “naked” burials were created. Multigeophysical surveys were collected over a 3‐year monitoring period. Bulk ground resistivity, electrical resistivity imaging, multifrequency ground‐penetrating radar (GPR), and grave and background “soil‐water” conductivity data were collected. Resistivity surveys revealed the naked burial had consistently low‐resistivity anomalies, whereas the wrapped burial had small, varying high‐resistivity anomalies. GPR 110‐ to 900‐MHz frequency surveys showed the wrapped burial could be detected throughout, with the “naked” burial mostly resolved. Two hundred and twenty‐five megahertz frequency GPR data were optimal. “Soil‐water” analyses showed rapidly increasing (year 1), slowly increasing (year 2), and decreasing (year 3) conductivity values. Results suggest resistivity and GPR surveys should be collected if target “wrapping” is unknown, with winter to spring surveys optimal. Resistivity surveys should be collected in clay‐rich soils.     

England,Englishness and Brexit

In the 1975 referendum England provided the strongest support for European integration, with a much smaller margin for membership in Scotland and Northern Ireland. By 2015 the rank order of ‘national’ attitudes to European integration had reversed. Now, England is the UK's most eurosceptic nation and may vote ‘Leave’, while Scotland seems set to generate a clear margin for ‘Remain’. The UK as a whole is a Brexit marginal. To understand the campaign, we need to make sense of the dynamics of public attitudes in each nation. We take an ‘archaeological’ approach to a limited evidence‐base, to trace the development of attitudes to Europe in England since 1975. We find evidence of a link between English nationalism and euroscepticism. Whatever the result in 2016, contrasting outcomes in England and Scotland will exacerbate tensions in the UK's territorial constitution and could lead to the break‐up of Britain.
