On evaluating evaluations

The act of evaluation requires an expenditure of resources. In Part I of this paper, we present a simple decision tree model borrowed from operations research to provide a conceptual framework for considering whether or not to commit such resources. In Part II, once the evaluation is carried out, we address the problem of evaluating the evaluation as a vehicle for producing useful information to decisionmakers. Evaluation inputs, processes, and outcomes are defined and discussed within the context of comprehensive evaluation of evaluations.     

Assessing mothers' and fathers' violence toward children as a function of their involuntary participation in family work

This study examines the association between parents' violence toward children and their involuntary participation in family work. Involuntary participation in family work is conceptualized as a form of role strain measured by the disparity between the amount of responsibility husbands and wives would prefer to assume in the home and the amount of family work they actually perform. The prediction guiding this research is that differences of this kind are more associated with mothers' violence than fathers'. Regression analysis with a national sample of parents supports this hypothesis. Nonetheless, the association between such role strain and violence is quite weak, suggesting that additional research is required in formulating and measuring this relationship.     

Government Risk-Financing Pools: An Assessment of Current Practices

Since 1970, state and local governments have experienced two “insurance crises;” the first occurred in the mid- to late-1970s and the second in the mid-80s. The result has been a twenty-year period of time in which state and local governments have been able to afford insurance only intermittently-if insurance has been available at all. In response to this problem, local governments, government associations, and state governments created alternative risk-finartcing mechanisms to provide coverage for themselves. These mechanisms, commonly referred to as self-insurance pools, enable local governments within a state to pool together risks and resources to finance the costs of fortuitous losses. In 1988, the first comprehensive examination of pooling practices was undertaken through a nationwide survey. This article reports the findings from the first follow-up study since the 1988 survey and further extends knowledge of pooling and pooling practices.     

Analysis of gunshot residue test results in 112 suicides

The results of gunshot residue (GSR) tests in 112 suicide cases investigated by the U.S. Army Criminal Investigation Command over a ten-year period are described. Only suicide cases in which there was certainty that the victim fired a weapon were examined in an effort to reduce ambiguous results. Previous case work research by Rudzitis indicated that positive GSR test results were encountered in suicides 62% of the time using various combinations of neutron activation analysis (NAA) and atomic absorption spectrophotometry (AAS). Threshold values of 0.2-micrograms antimony and 0.3-micrograms barium (0.2-micrograms antimony and 0.5-micrograms barium after 1985) used by the U.S. Army Criminal Investigation Laboratory resulted in positive GSR results in suicide cases 38% of the time. The effects of time, location of body, handling of the body, weapon type, caliber, and condition of the hands on GSR results are examined. Case studies involving suicides by unit armorers are discussed.     

Comparison of results for quantitative determination of morphine by radioimmunoassay, enzyme immunoassay, and spectrofluorometry.

The quantitative results (accuracy and precision) for determination of opiates by radioimmunoassay (RIA), enzyme immunoassay (EMIT), and spectrofluorometry on split samples are compared. A variety of physiological samples were studied, including random urine from a methadone maintenance clinic and postmortem urine, blood, bile, brain, and lung tissue from heroin-induced or heroin-related deaths. The opiate concentrations detected by the two immunoassay methods were in good agreement with each other in the absence of interfering substances which are believed to react with the antimorphine antibodies. The immunoassay results were in agreement within the relative standard deviation with the fluorometry results in 55% of the urine samples and 80% of the blood samples. The immunological methods are superior to fluorometry for quantitation of morphine in urine samples due to quenching interferences in fluorometry from urine. They were comparable to fluorometry for quantitation of morphine in blood samples.
