Forensic Mental Health Clinical Evaluation: An Analysis of Interstate and Intersystemic Differences

Forensic mental health evaluation systems have undergone major changes during the past two decades, and the variability of service delivery systems across states is significant. We compared assessments of competence to stand trial and criminal responsibility in three states with different systems for forensic mental health evaluations: Michigan, Ohio, and Virginia. Although all three states use comparable legal criteria to judge competence and criminal responsibility, we found large, statistically significant differences among the states in the proportion of defendants referred for evaluation who were assessed as incompetent or not criminally responsible. In addition, significant differences were found in the diagnostic and offense categories of defendants referred for evaluation. Our findings suggest that the structure of a system for providing forensic evaluation services may significantly affect both the group of individuals referred for evaluation as well as evaluation outcome.     

A rent-seeking model of TELs

Tax and expenditure limits or TELs are constitutional or statutory constraints on the fiscal powers of government. Since the taxpayer revolt beginning in the late 1970s, TELs have been introduced in twenty-three states. In recent years a number of studies attempting to test the impact of TELs have found little evidence that TELs significantly reduced the growth of state government. In this study we challenge the implicit Leviathan model that underlies most of these studies, and offer an alternative rent-seeking model. Econometric tests provide support for this rentseeking model, and indicate that TELs have been significant in reducing the growth of state government, at least in the short run. “... the very principle of constitutional government requires it to be assumed, that political power will be abused to promote the particular purpose of the holder; not because it always is so, but because such is the natural tendency of things, to guard against which is the especial use of free institutions”     

Potential and pitfalls in establishing the provenance of Earth-related samples in forensic investigations

Earth scientists are often asked to establish or constrain the likely provenance of very small quantities of earth-related material as part of a forensic investigation. We tested the independent and collective interpretations of four experts with differing analytical skills in the prediction of sample provenance for three samples from different environmental settings. The methods used were X-ray diffraction, scanning electron microscopy, the assessment of pollen assemblages, and structural characterization of organic matter at the molecular level. Independent interpretations were less accurate than those where multiple techniques were combined. Collective interpretation was very effective in the assessment of provenance for two of the three sites where the mineralogy and plant communities were distinctive. At the other site, although the mineralogical analysis correctly identified the Triassic mudstone soil parent material, Carboniferous spores from domestic coal were initially interpreted as deriving directly from bedrock. Such an interpretation could be a common pitfall owing to anthropogenic redistribution of material such as coal.
