A relative newcomer to personality assessment in the area of law enforcement is the Personality Assessment Inventory, or PAI.
Earlier MMPI research in the area of police selection has focused upon antisocial behavior, control of aggression, and validity
indices, particularly the L scale. In this study T scores for 800 male and female police officer candidates on the PAI scales
Negative Impression (NIM), Positive Impression (PIM), Antisocial-Antisocial Behaviors (ANTA), Antisocial-Egocentricity (ANTE),
and Antisocial-Stimulus Seeking (ANTS) were used as predictors of the criterion variables Insubordination, Excessive Citizen
Complaints, and Neglect of Duty. Highly significant coefficients were obtained for ANTE as a predictor of Insubordination
and Excessive Citizen Complaints. For Neglect of Duty, two significant coefficients were obtained, one for ANTS and another
for NIM. Discussion centered on the fact that egocentricity is a predictor of Insubordination and Excessive Citizen Complaints,
and Neglect of Duty is related to stimulus seeking.

Abstract: Recently a small sampled cadaver study (n = 4) suggested that the human eyeballs are placed closer to the orbital roof and lateral orbital wall as first reported in the anatomical literature many years previously. This contrasts with central positioning of the eyeball within the orbit as advocated by the facial approximation literature. Given the limits of such small samples, this study re-examined globe position in nine new cadavers to help clarify which relationship is accurate. The results essentially confirm prior empirical findings except that the mean lateral divergences from the orbit center were found to be larger—the eyeball was found to be “displaced” 1.4 mm superiorly and 2.4 mm laterally. Medians calculated across all 13 cadavers from this study and the above-mentioned recent report refine these measurements to 1.4 and 2.3 mm respectively. Globe projection values were identical to those observed for living individuals (c. 16 mm). 相似文献

In an attempt to discover the major predictors of parole decision-making in one southeastern state, this study examined the cases of 762 inmates under the supervision of the Alabama Department of Corrections who were eligible for parole from June 1, 1993 through May 31, 1994. Of the 762 eligible inmates, only 138 (18 percent) were granted parole. Using parole disposition (granted or denied) as the dependent variable, this study investigated the offense, offender, and general parole variables and their impact on parole decisions. Logistic regression findings indicated that the strongest predictors of parole release decisions were the length of the original sentence assessed for the offense, the total number of felonies for which the inmate was serving time, and the warden and senior officers' recommendations. These variables, which were also significant at the bivariate level of analysis, explained approximately 47 percent of the variation in the dependent variable. A major concern of the study was the generalizability of the findings. 相似文献

Images of private forces in Iraq—killed and mutilated in Fallujah, implicated in prisoner abuse at Abu Ghraib, and shooting up civilian vehicles—have provided a dramatic illustration of the role private security companies (pscs) now play in U.S. military operations. Though the United States’ use of contractors on the battlefield is not entirely new, the increased number of contractors deployed and the use of private security forces to perform an escalating number of tasks has created a new environment that poses important trade-offs for U.S. policy and military effectiveness and for U.S. relations with other states. This article outlines the history of U.S. contractors on the battlefield, compares that with the use of private security in Iraq, discusses the benefits and risks associated with their use, and proposes some trade-offs that decision-makers in the United States should consider while contemplating their use in the future. 相似文献
