Prior studies have found that symbolic racism and negative African-American stereotypes are linked to public preferences for punitive criminal justice policy. But prior studies have mostly focused attention on White respondents and have not adequately examined whether the effects of symbolic racism and negative African American stereotypes are the same across race and ethnicity. This study used the 2000 American National Election Study data to fill this gap in the empirical literature. The study found that the effects of symbolic racism were broad and generally impact Whites, African-Americans, and members of other races/ethnicities the same. The effects of negative African-American stereotype were more limited. This variable predicted punishment policy preference for members of other races/ethnicities and there were significant differences in how stereotypes impacted policy preferences across race and ethnicity. Implications for theory are discussed.  相似文献

Purpose. This study investigated the influence of psychopathy and sex offender subtype on criminal history, probability of being granted conditional release, and performance while on conditional release in a diverse group of violent offenders. We predicted that psychopathic sexual offenders would be associated with relatively prolific violent and sexual offending, a high probability of successful conditional release applications despite their past behaviour (resulting from ‘putting on a good show’ in a parole hearing), and poor performance in the community. Methods. Information was gathered via a correctional file review of 310 Canadian male federal offenders. Offenders were categorized into groups based on their sexual offence history (non‐sex offender, rapist, child molester, or mixed rapist/molester) and Psychopathy Checklist – Revised (PCL‐R; Hare, 2003) ratings. Their offences (sexual, violent, or non‐violent) and their complete conditional release histories were coded. Results. Psychopathy was associated with more violent and non‐violent, but not sexual, offences. A significant interaction between psychopathy and offender subtype revealed that psychopathy was associated with a greater number of sex offences within child molesters. High‐psychopathy offenders (both sexual and non‐sexual offenders) were about 2.5 times more likely to be granted conditional release than non‐psychopathic offenders. Conclusions. Psychopathy is associated with more prolific sexual offending among child molesters and – despite their extensive criminal histories and high recidivism rate – a great proficiency in persuading parole boards to release them into the community. Specialized education and training in dealing with psychopathic offenders is urgently needed.  相似文献

Notions of human agency are a prominent part of some but not all criminological theories. For example, McCarthy (Annu Rev Sociol 28:417–442, 2002) argues that rational choice theory, which allows persons great involvement in decision making, is more congenial with notions of human agency than others. It would appear from his argument that rational choice theory offers fertile ground to develop a clearly defined role for human agency in criminal behavior. In this paper we have taken up McCarthy’s view and argue that an important part of what is human agency consists of thoughtfully reflective decision making. We outline four elements of thoughtfully reflective decision making, and claim that it is a characteristic that varies both across persons and within persons over time. It is in short the process by which good decisions are made because by using this process one increases the likelihood that choices made will be consistent with preferences. We develop a clear operational definition of thoughtfully reflective decision making and link it to the concept of human agency. We also articulate testable hypotheses about the short-term and longer-term implications of thoughtfully reflective decision making. We conclude with a discussion of what we think lies ahead for future conceptual and empirical work.

Researchers have argued that the creation of citizen oversight often involves debate between those that support its use and the police which do not. Police unions, for example, have a long history of objecting to the creation of oversight, especially during collective bargaining. Minority demands for police reform, on the other hand, can lend support for its implementation, especially after a highly publicized case of misconduct between the police and minority citizens. Using a retrospective approach, this study examined the extent to which these opposing forces influenced the existence of oversight. Findings suggest that departments that engage in collective bargaining were no more likely to use an oversight agency than departments that did not engage in collective bargaining. Cities with large percentages of African Americans, however, were more likely to have an existing oversight agency.  相似文献

Oral fluid is an interesting alternative matrix for drug testing in many environments, including law enforcement, workplace drug testing, and drug treatment facilities. Performance characteristics of the FDA-cleared, qualitative, Cozart RapiScan Opiate Oral Fluid Drug Testing System (Opiate Cozart RapiScan System or Opiate CRS) were compared to the semi-quantitative Cozart Microplate EIA Opiate Oral Fluid Kit (Opiate ELISA) and to gas chromatography/mass spectrometry (GC/MS). The following oral fluid opiate cutoffs were evaluated: the GC/MS limit of quantification (LOQ) of 2.5 mg/l; 15 microg/l currently used for oral fluid testing in the United Kingdom (UK); 30 microg/l (Opiate CRS cutoff); and 40 microg/l, the proposed Substance Abuse and Mental Health Services Administration (SAMHSA) cutoff. Subjects provided informed consent to participate in this IRB-approved research and resided on the closed research ward throughout the study. Three oral codeine doses of 60 mg/70 kg were administered over a 7-day period. After a 3-week break, subjects received three doses of 120 mg/70 kg within 7 days. Oral fluid specimens (N = 1273) were analyzed for codeine (COD), norcodeine (NCOD), morphine (MOR) and normorphine (NMOR) by GC/MS with an LOQ of 2.5 microg/l for all analytes. MOR and NMOR were not detected in any sample; 26.5% of the specimens were positive for COD and 13.7% for NCOD. Opiate CRS uses a preset, qualitative cutoff of 10 microg/l; this is equivalent to 30 microg/l in undiluted oral fluid as the oral fluid collection process involves a 1:3 dilution with buffer. Sensitivity, specificity, and efficiency of Opiate CRS compared to Opiate ELISA were 98.6, 98.1, and 98.2% at a 30 microg/l cutoff and 99.0, 96.2, and 96.6% at a 40 microg/l cutoff. Compared to the much lower GC/MS LOQ of 2.5 microg/l, sensitivity, specificity and efficiency were 66.8, 99.3 and 90.7%. Increasing the GC/MS cutoff to the current UK level yielded performance characteristics of 81.5% (sensitivity), 99.3% (specificity), and 95.4% (efficiency). Using a GC/MS cutoff identical to the preset Opiate CRS cutoff yielded sensitivity, specificity, and efficiency of 88.5, 99.2, and 97.5%, respectively. At the proposed SAMSHA confirmation cutoff of 40 microg/l, sensitivity increased with little change in specificity and efficiency (91.3% sensitivity, 98.9% specificity, and 97.5% efficiency). Oral fluid is a suitable matrix for detecting drugs of abuse. Opiate CRS, with a 30 microg/l cutoff, is sufficiently sensitive, specific and efficient for oral fluid opiate analysis, performing similarly to Opiate ELISA at the same cutoff, and having performance characteristics >91% when compared to GC/MS at the proposed SAMHSA cutoff.  相似文献

Deterrence theory describes a process of offender decision making that consists of two linkages—one in which official sanctions and other information affect a would-be offenders perceptions about the risks of criminal conduct, and another in which such perceptions influence the decision whether or not to offend. Decades worth of empirical research has concentrated virtually exclusively on this latter linkage, and in so doing, has produced an incomplete account of the deterrence process. This article develops a model of how perceptions of sanction certainty are modified in response to an individuals involvement in criminal activity and the consequences (if any) therefrom. Implications of the model are tested with data from a multi-wave, panel survey of 1,530 high school students from the southeastern U.S. Key findings include: the manner in which new information affects perceived certainty depends on the level of perceived certainty before the new information is received, and the extent of peer offending was one of the most influential factors in determining change in perceived sanction certainty over time.  相似文献

Two methodological issues within the pretrial publicity (PTP) literature were examined in the present experiment: the effect of emotional versus factual PTP and the effect of presenting PTP through different media. Emotional and factual PTP were constructed that differed in level of emotionality, but produced the same degree of bias. The PTP was presented in either a videotaped or written format. Although there was a significantly biasing effect of PTP overall compared to a control condition, no significant difference was found either between factual and emotional PTP or between video and written PTP.  相似文献
