On January 13, 1978, after nearly 30 years of public service, Burtell Jefferson became the first African American to serve as chief of the Metropolitan Police Department of Washington, D.C. This profile describes his personal and professional journey and describes—from the perspective of a cadre of active and retired police chiefs and chief executive officers—the impact of Jefferson's career on the Metropolitan Police Department and policing in America more broadly. Jefferson's story, an exemplary illustration of public sector leadership, has profound implications for contemporary efforts to ensure the equality of employment opportunity. Jefferson's career provides a model of effective leadership that is applicable across organizations and sectors. He not only led his organization well but also encouraged and developed generations of future leaders. 相似文献

Nonphysical abuse of women is receiving increased attention, but research with clinical samples of batterers has not substantially addressed the risk markers of nonphysical abuse. A multisite sample of batterer program participants (n = 840) with a longitudinal 15-month follow-up was used to identify risk markers. Logistic regressions were computed with batterer characteristics for 4 categories of nonphysical abuse (i.e., control, verbal, threats, combined) reported by the batterer's female partners during the follow-up. The only substantial and consistent risk markers were nonphysical and physical abuse prior to program intake and program dropout. The programs appear to help reduce the abuse. Other significant risk markers varied across the categories of nonphysical abuse, suggesting that the categories do not form a continuum or hierarchy of abuse. Recurrent abuse, moreover, continues to be more difficult to predict in clinical samples than in the general population. 相似文献

Individuals with psychopathy typically are viewed as incurable cases that should be diverted from treatment settings to environments where their behavior can be monitored and controlled. The prevailing clinical conviction that psychopaths are untreatable has crucial implications, given the scarcity of mental health care resources, the number of legal contexts that call for assessment of treatability, and the explosion of research on psychopathy and violence risk over recent years. Based on a sample of 871 civil psychiatric patients (including 195 potentially psychopathic and 72 psychopathic patients), this study explores the relations among psychopathy, receipt of outpatient mental health services in real-world settings, and subsequent violence in the community. The results suggest that psychopathic traits do not moderate the effect of treatment involvement on violence, even after controlling statistically for the treatment assignment process. Psychopathic patients appear as likely as nonpsychopathic patients to benefit from adequate doses of treatment, in terms of violence reduction. We interpret these results in light of prior research with offenders and analyze their implications for future research, policy, and practice. 相似文献

The capability of Fourier transform infrared (FTIR) spectroscopic imaging to provide detailed images of unprocessed latent fingerprints while also preserving important trace evidence is demonstrated. Unprocessed fingerprints were developed on various porous and nonporous substrates. Data-processing methods used to extract the latent fingerprint ridge pattern from the background material included basic infrared spectroscopic band intensities, addition and subtraction of band intensity measurements, principal components analysis (PCA) and calculation of second derivative band intensities, as well as combinations of these various techniques. Additionally, trace evidence within the fingerprints was recovered and identified. 相似文献

Empirical studies of violence and mental illness have used many different methods. Current state-of-the-art methods gather
information from both subject and collateral interviews as well as official records. Typically these sources are treated as
additive. Any report of a violent incident from any source is treated as true and all reported incidents are added to generate
estimates of frequency. This paper presents a new statistical technique that uses the level of agreement between the sources
of data to adjust those estimates. The evidence suggests that, although the additive technique for using multiple sources
correctly estimates how many people are involved, it substantially underestimates the number of incidents. The new technique
substantially reduces both false negatives and false positives. 相似文献

Objectives
A broad research literature in criminology documents key aspects of how criminal offending develops and changes over the life span. We contribute to this literature by showcasing methods that are useful for studying medium-term patterns of subsequent criminal justice system involvement among a sample of serious adolescent offenders making the transition to early adulthood.Methods
Our approach relies on 7 years of post-enrollment follow-up from the Pathways to Desistance Study. Each person in the study was adjudicated delinquent for or convicted of one or more relatively serious offenses during adolescence. Their local jurisdiction juvenile court petition records and their adult FBI arrest records were systematically searched.Results
We estimate in-sample 7 year recidivism rates in the 75–80 % range. Our analysis also provides recidivism rate estimates among different demographic groups within the sample. Extrapolated long-term recidivism rates are estimated to be on the order of 79–89 %.Conclusions
The Pathways data suggest that recidivism rates of serious adolescent offenders are high and quite comparable to the rates estimated on other samples of serious offenders in the extant literature. Our analysis also reveals a pattern of heightened recidivism risk during the earliest months and years of the follow-up period followed by a steep decline.908.

Objectives
Conventional statistical modeling in criminology assumes proper model specification. Very strong and unrebutted criticisms have existed for decades. Some respond that although the criticisms are correct, there is for observational data no alternative. In this paper, we provide an alternative.Methods
We draw on work in econometrics and statistics from several decades ago, updated with the most recent thinking to provide a way to properly work with misspecified models.Results
We show how asymptotically, unbiased regression estimates can be obtained along with valid standard errors. Conventional statistical inference can follow.Conclusions
If one is prepared to work with explicit approximations of a “true” model, defensible analyses can be obtained. The alternative is working with models about which all of the usual criticisms hold.909.
Parole has long been a linchpin of correctional practices but few studies have examined discretionary parole release in a female population. The current study examines factors, both static risk and dynamic needs, that influence parole decision making in a rural female jail population. The researchers collected data on parole releases from a rural county jail over a 3-year period beginning in 2012 (N?=?138). Offenders obtained a recommendation for parole release from a reentry assessment team that met at the jail each month to evaluate cases for parole eligibility. Logistic regression was used to explain variance in the factors considered by the reentry assessment team and it was evident that both static risk factors and dynamic needs play a role in discretionary parole release. We also examined obstacles or challenges that female offenders face when paroling to a rural location. Several policy recommendation related to the study are addressed. 相似文献

The objective of this paper was to determine factors predictive of contraceptive embarrassment and to determine the relationship of contraceptive embarrassment to contraceptive use among young unmarried females. Contraceptive embarrassment was measured by an eight-item scale (a=0.88]. Data were obtained from 265 nonvirgin high school and university females who were currently dating. Using simple multiple regression, 30% of the variance of the embarrassment scale was explained, with the most important predictors being parental attitude to premarital intercourse and sexual guilt. Other significant predictors were attitude to planning ahead to use contraception, perveived difficulty in obtaining contraceptive devices, and peer attitudes toward premarital intercourse. The embarrassment scale had significant correlations with contraceptive use.Sponsorship from Health and Welfare Canada through Family Planning Grant No. 4470-5-10 provided for the data collection, and sponsorship from the National Institute of Child Health and Human Development, DH&W, Contract No. N01-HD-92809 provided for the data analysis.Received his Ph.D. from Department of Sociology, Iowa State University and is interested in the sociology of adolescence, particularly dating, sexual relations, and use of contraception. 相似文献
