Priming Unconscious Racial Stereotypes About Adolescent Offenders

Two studies examined unconscious racial stereotypes of decision makers in the juvenile justice system. Police officers (Experiment 1) and juvenile probation officers (Experiment 2) were subliminally exposed to words related to the category Black or to words neutral with respect to race. In a presumably unrelated task, officers read 2 vignettes about a hypothetical adolescent who allegedly committed either a property crime (shoplifting from a convenience store) or an interpersonal crime (assaulting a peer). The race of the offender was left unstated and the scenarios were ambiguous about the causes of the crime. Respondents rated the hypothetical offender on a number of traits (e.g., hostility and immaturity) and made judgments about culpability, expected recidivism, and deserved punishment. They also completed a self-report measure of conscious attitudes about race. As hypothesized, officers in the racial prime condition reported more negative trait ratings, greater culpability, and expected recidivism, and they endorsed harsher punishment than did officers in the neutral condition. The effects of the racial primes were not moderated by consciously held attitudes about African Americans. The implications of the findings for racial disparity in the juvenile justice system and for changing unconscious stereotypes were discussed.     

Unsuspected meningoencephalitis in a case of assault by blunt force trauma

Reported is a case of an assault causing extensive blunt force injuries in which the clinical, radiologic, and postmortem findings were all consistent with death resulting from brain damage arising from the assault. The assailant was charged with murder. Subsequent full neuropathologic (including histologic) examination revealed the unsuspected finding of a widespread meningoencephalitis but no evidence of significant traumatic brain damage. The contributions of the infective process and of the trauma to death were felt to be unclear and a guilty plea to attempted murder was accepted. This case highlights the importance of a full neuropathologic examination, including histology, in cases of trauma to the head, even when the cause of death may initially appear obvious.     

A potential metallographic technique for the investigation of pipe bombings

This study was conducted in an attempt to develop a metallographic method for the investigation of pipe bombings. Three common pipe materials, ASTM A53 steel, AISI 304L stainless steel, and 6061-T6 aluminum, were shock-loaded using five high explosives and three propellants. The explosives used were ANFO, Composition C4, C6 detasheet, nitroglycerine-based dynamite, and flake TNT. The propellants used were FFFFg black powder. Red Dot smokeless powder, and Turbo Fuel A. The post-blast microstructure, hardness, and, in the case of 304L, transformed martensite content were examined for each test. The damage done to the microstructure was found to increase with increasing detonation velocity of the explosives and increase in pressure generated by the shock-metal interaction. Material hardness and, in the case of 304L, martensite content showed a sharp increase followed by a plateau as the shock pressure and detonation velocity increased.     

Sharing governmental authority: Blue Cross and hospital planning in New York City.

Hospital planning in New York has been since the 1930s an intensely political process with high stakes. The leaders of Blue Cross and their allies used the hospital planning process in the city and the state as a means to extend and protect corporate authority in what they took to be the public interest. When Blue Cross was established in the 1930s, its leaders used the mechanisms of formal planning as part of their solution to pressing problems in the organization and distribution of hospital services. In the decade after World War II, Blue Cross had an immense impact on hospital planning in New York as a result of its growth and its underwriting policies. Conflicts between Blue Cross and state regulators beginning in the 1950s led to a new formulation of the politics of planning. Blue Cross became a partner with the state in regulating hospitals. The state and Blue Cross behaved as co-regulators until the 1980s. The interpretation in this paper revises the earlier accounts of health politics in New York by Law (1976) and Alford (1975).     

Effect of hypothermia on breath-alcohol analysis

Mild hypothermia, induced by experimental immersion of ten subjects in cold water, distorted the decay curve of breath ethanol of intoxicated subjects by as much as 22% while not altering overall ethanol clearance rate. The results provide in vivo verification of the in vitro temperature correction factor of 6.8% X degrees C-1, and support previous recommendations that temperature monitoring be included in procedures for breath-ethanol testing. We recommend that mouth temperature be obtained before breath sampling to screen for abnormal body temperature and to allow for potential use of a temperature correction factor. This modification to existing analytical procedures would help to optimize the reliability of breath-ethanol analysis in predicting blood-ethanol concentration.     

The Effect of a Standard to Improve Person Descriptions by Children

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger and were then later asked to describe and answer various questions about that person using a third-person standard/comparison. Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where female - did have a significant effect on the recall ability of male participants.
