Implicit theories of criminal responsibility

Three questions relevant to insanity decisions were examined: (a) What informational cues are weighed most heavily in the attribution of criminal responsibility? (b) How do verdict forms influence these attributions? And (c) How do individuals' beliefs about insanity and responsibility influence decision making? Undergraduate subjects (n=181) responded to vignettes portraying an act by a mentally disordered defendant. Psychiatric jargon was avoided, so that attributions were not a function of diagnostic terminology. It was found that, under the traditional scheme of not guilty by reason of insanity (NGRI) vs. guilty, level of mental disorder (schizophrenia vs. personality disorder) was the primary determinant of insanity decisions. Also, insanity judgments were more likely to be made for acts performed without planful intentionality. Under the alternative scheme of NGRI vs. guilty but mentally ill (GBMI) vs. guilty, mental disorder still controlled NGRI verdicts; a bizarre act increased the likelihood of a GBMI over a guilty verdict; and the GBMI verdict option reduced markedly the proportion of psychotic defendants found NGRI and the proportion of personality disordered defendants found guilty. There were no significant differences between diagnostic groups in the likelihood of being found GBMI. Most subjects preferred to utilize the GBMI option as a compromise verdict even in the face of very severe mental illness. Attitudinal data revealed considerable variation in agreement with the classic moral logic of the insanity defense and accounted for a significant amount of the variance in insanity decisions. The implications for both social policy and future research are discussed.     

Toxicology and Circumstances of Completed Suicide by Means Other than Overdose*

Abstract: To determine the prevalence and circumstances of psychoactive substances amongst nonoverdose completed suicide, 1436 consecutive cases autopsied at the NSW Department of Forensic Medicine over the period 1/1/1997–12/31/2006 were analyzed. Substances were detected in 67.2% of cases, and illicit drugs in 20.1%. Alcohol was present in 40.6% of cases. Males were more likely to be positive for alcohol, cannabis, and psychostimulants, and females for pharmaceuticals. Illicits were associated with younger age. Alcohol was most prominent amongst toxicity cases, as were opioids, psychostimulants amongst gunshot cases, and pharmaceuticals amongst drownings. Cases in which drug and alcohol histories were noted were more likely to have a substance detected. Alcohol was more common where a suicide note was left and where relationship problems were involved. Pharmaceuticals were more common where a previous attempt was noted. Licit and illicit substances are strongly associated with suicide, even when the method does not involve drug overdose.     

THE LIMITED ROLE OF CHANGING AGE STRUCTURE IN EXPLAINING AGGREGATE CRIME RATES*

Changes in the age structure are shown to have a limited impact on aggregate crime rates. Even the dramatic transformation of the age distribution accompanying the baby boom shifted crime rates by no more than 1 % per year. Projected changes in the age distribution between 1995 and 2010 will lead to slight declines in per capita crime rates. These results are at odds with recent predictions of an impending demographically driven crime wave. Such predictions have focused exclusively on a rise in juvenile crime and ignored the offsetting decreases among adults.     

Terrorist Decision Making and the Deterrence Problem

An ongoing debate among policymakers and terrorism scholars concerns the effectiveness of deterrence as a counterterrorism tool. Absent from the debate is a discussion of the complex nature of terrorist decision making. Decisions are made at varying levels in a terrorist organization, often by actors having different motives, resulting in behavior that is not always fully rational. This article identifies several circumstances when terrorist behavior is not the product of an entirely unitary, rational decision-making process, and therefore highlights when deterrence policies will be least effective. It concludes with some policy implications for understanding when deterrence policies are most likely to succeed and how to address terrorism in other situations.

Cultivating Public Service Motivation through AmeriCorps Service: A Longitudinal Study

The public service motivation literature has helped scholars and practitioners better understand who is attracted to public service and why. However, little is understood about how public service motivation in individuals may be cultivated or how it changes over time. This article uses panel data collected by the Corporation for National and Community Service to track the longitudinal effects of participation in the AmeriCorps national service program on participants’ public service motivation. Findings reveal that participation in AmeriCorps programs had positive effects on participants’ levels of commitment to the public interest and civic awareness immediately after the program; many of these program effects were sustained seven years later. However, when observed in isolation, the comparison group showed significant declines in levels of commitment to public interest and civic awareness over an eight‐year period, suggesting that public service motivation may initially decline upon entry into a public service career.     

The quantification of fingerprint quality using a relative contrast index

Research into fingermark enhancement techniques has traditionally used visual comparisons and qualitative methods to assess their effectiveness based on the quality of the developed fingermark. However, with increasing research into the optimisation of these techniques the need for a quantitative evaluative method has arisen. Parameters for acceptable fingerprint quality are not well defined and generally encompass clear, sharp edges and high levels of contrast between the fingermark ridges and background material. Using these current parameters, a conclusive measurement of fingerprint quality and thus the effectiveness of development techniques cannot be achieved.This study presents a model through which an aspect of fingerprint quality can be objectively and impartially measured based on a relative contrast index, constructed through measuring the reflective intensity of the fingermark ridges against the background material. Using a fibre-optic spectrophotometer attached to a microscope with axial illumination, the intensity counts of the ridge detail and background material were measured and a logarithmic contrast index constructed. The microscope and spectrophotometer parameters were experimentally tested using a standard colour resolution chart with known reflective properties. The protocol was successfully applied to four sample groups: black inked fingerprints on white paper; latent fingermarks on white paper developed separately with ninhydrin and physical developer; and fingermarks in blood deposited on white tiles and enhanced with amido black. The contrast indices obtained quantitatively reflect the level of contrast and provide an indication of fingerprint quality through a numerical representation rather than previous qualitative methods. It has been suggested that the proposed method of fingerprint quantification may be viable for application in the forensic research arena as it allows the definitive measurement of contrast to aid the evaluation of fingermark detection and enhancement techniques.
