Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.  相似文献

Various studies have shown that women with psychopathy tend to commit crimes that are less violent than those of psychopathic men. The present study was designed to address the influence of psychopathy on the crimes committed by female offenders. A national sample of female offenders found NGRI or of diminished responsibility and at risk for criminal recidivism (OPG patients) was compared with a sample of female offenders who were convicted and imprisoned. Results of this comparison between the two groups of female offenders indicate that psychopathy is a transversal psychopathological dimension which may or may not be associated with other mental disorders. In both samples, the most commonly reported offenses among women with high PCL‐R scores were minor offenses, not particularly violent, but they appear to be related to typical psychopathic features such as superficial charm, pathological lying, and manipulation.  相似文献

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.  相似文献

The literature on child sexual abuse (CSA) perpetrated by female sexual offenders (FSOs) is exiguous, and many studies have focused on judicial databases. The present retrospective study, instead, analyzed clinical and judicial data of a group of both victims and alleged FSOs, to additionally include women who have not been convicted by the criminal justice system, but who hold strong clinical suspicions of being perpetrators of CSA. The medical records and the Court files of 11 children and their eight suspected FSOs have been collected and critically reviewed in light of the literature to date. This approach allowed for a deeper understanding of the relationship between child and FSO. The authors hypothesize that the victims’ severe psychopathological outcomes were a result of a failure to develop appropriate attachments with their prospective caregivers, which could have been damaged by the pathological relationship with FSOs, who were the victims’ caregivers.  相似文献

ABSTRACT

Recently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics.  相似文献

Governments are increasingly implementing smart and digital approaches to promoting citizen participation. However, whether online participation platforms are tools that improve inclusivity in citizen participation remains underexplored. To address this gap, this article focuses on the role of recruitment messages and their effect on participation in an online participation platform by gender and age. A field experiment with a neighborhood census sample (N = 6,066) shows that online participation dips for younger and older citizens and is equal among women and men. For the age groups between 60 and 75, differences in the control and intervention recruitment messages significantly impacted participation. These findings can help public managers tailor recruitment strategies to facilitate inclusive participation and represent a first step toward learning what types of messages are effective for whom.  相似文献

The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.  相似文献
