Predicting troublemaking offenders: A discriminant analysis

Violence, attempted escapes, thefts, persistent rule violations, and other extreme forms of maladaptive prison behavior have created problems for correctional authorities since congregate confinement became the watchword in American corrections. The evolution of prisoner classification programs has aided prison administrators in their attempts to recognize potential behavioral problems but the subjective nature of a number of state classification models has resulted in a continuous wave of litigation and fiscal constraints. The objective of this paper is to provide a prediction model to assist in the classification of adult prisoners. Data on all members of the Georgia adult, male prison population from 1971 to 1978 were used as a baseline. A sample was chosen from inmates in long-term disciplinary segregation whose files contained all necessary demographic, psychometric and judicial variables. A discriminant analysis of these two groups identified 14 variables which correctly assigned inmates in 85% of the cases. The predictive variables include both demographic and personality characteristics.     

Planning and conducting federally funded scientific research in Nigeria

During the past two decades Nigeria has invested heavily in scientific research, by developing country standards. Yet these investments at best have had only marginal impacts on the activities of the production and service sectors even though there are many priority development activities which could benefit from inputs from Nigerian researchers. At the national level efforts to direct or even co-ordinate the planning and budgeting of research have been seriously hampered by frequent changes in organizational responsibilities and by repeated budget cuts. Historically, the activities of the federal research institutes have been poorly tuned to the interests and capabilities of the potential users of their research products. Neither these institutes nor the universities with research activities are in a position to develop products or processes which can compete with imported technologies that are saturating the economy. However, the research institutes, and to a lesser extent the universities, should make greater contributions in applying science to improved use of the nation's natural resource endowments, although significant changes in research management at the project level are needed if this objective is to be realized. The Government should provide incentives to the multinational companies operating in Nigeria to develop joint programmes with the research institutes and universities as one mechanism for diffusing the administrative and technical capabilities of the companies. Meanwhile, selected public sector enterprises should be encouraged to expand technological innovation efforts which could be directly applied to their production activities.     

Distribution of morphine in body fluids and tissues in fatal overdose

Two cases of fatal overdose with morphine are presented. Large amounts of the drug were involved in both cases, one by oral ingestion, the other by intravenous injection. Morphine concentrations in various body fluids and tissues are compared to those in the literature.
