Few studies have compared performance on neurocognitive measures between violent and nonviolent schizophrenia samples. A better understanding of neurocognitive dysfunction in violent individuals with schizophrenia could increase the efficacy of violence reduction strategies and aid in risk assessment and adjudication processes. This study aimed to compare neuropsychological performance between 25 homicide offenders with schizophrenia and 25 nonviolent schizophrenia controls. The groups were matched for age, race, sex, and handedness. Independent t‐tests and Mann–Whitney U‐tests were used to compare the schizophrenia groups’ performance on measures of cognition, including composite scores assessing domain level functioning and individual neuropsychological tests. Results indicated the violent schizophrenia group performed worse on measures of memory and executive functioning, and the Intellectual Functioning composite score, when compared to the nonviolent schizophrenia sample. These findings replicate previous research documenting neuropsychological deficits specific to violent individuals with schizophrenia and support research implicating fronto‐limbic dysfunction among violent offenders with schizophrenia.  相似文献

This study is part of a larger research project on police crime in the United States. Police crimes are those criminal offenses committed by sworn law enforcement officers who have the general powers of arrest. Profit-motivated police crime involves officers who use their authority of position to engage in crime for personal gain. This study reports the findings on 1,591 cases where a law enforcement officer was arrested for one or more profit-motivated crimes during the seven-year period 2005–2011. The profit-motivated arrest cases involved 1,396 individual officers employed by 782 state, local, special, constable, and tribal law enforcement agencies located in 531 counties and independent cities in 47 states and the District of Columbia. Our data is the first systematic study of profit-motivated police crime. The study describes the nature of this form of police misconduct in terms of several dimensions, including the characteristics of police who perpetrate these crimes, where it occurs, the specific criminal charges, and the contexts within which profit-motivated police crime is punished through police agencies and the criminal courts.  相似文献

One method that has been touted to help end mass incarceration is using intermediate sanctions. While intermediate sanctions often present as attractive options, there is evidence that as practiced, these sanctions often result in net widening. One of the most common forms of intermediate sanctions are drug courts, which are often viewed as progressive alternatives to locking up people with substance abuse problems. However, along with the dangers of net widening, scholars have shown that many people admitted to drug courts do not seem to have substance abuse problems and could benefit from lesser criminal justice interventions. In the current study, we analyzed intake data from a drug court to determine: (1) what charge(s) drug participants had and (2) how they became involved with the criminal justice system. Among important findings were that a large number of drug court participants were arrested for the possession of one drug only (often marijuana) and that more than half of participants came to the attention of the criminal justice system through a traffic stop rather than through repeated encounters with the criminal justice system.  相似文献

Images of police officers riding in armored vehicles and carrying military-grade weapons have become part of the public consciousness following the events in Ferguson, Missouri and several other high-profile police–citizen encounters. Although a great deal of research has investigated how and why US citizens perceive the police in various ways, almost no empirical work has asked how citizens perceive the militarization of the police. The current study analyzes data from a survey of 1005 US citizens to identify characteristics that are related to support for the use of military weapons and vehicles by local police departments. The results indicate that several demographic factors and perceptions of crime and the police are significantly related with citizen support for the militarization of the police. The implications of this research are discussed.  相似文献

It is thought that deaf or hard of hearing individuals are at greater risk of abuse than the hearing population. The purpose of this paper is to systematically examine and integrate existing literature to determine the prevalence rates of neglect, emotional, physical and sexual abuse and intimate partner violence (IPV). A set of inclusion and exclusion criteria was determined. Following this a comprehensive search of numerous databases was conducted. Fourteen studies met the inclusion criteria. Eight studies reviewed the prevalence of sexual abuse, seven reviewed physical abuse, five reviewed emotional abuse, four reviewed neglect and six examined IPV. This exceeds 14 as numerous studies examined multiple types of abuse. Quality assessment indicated 12 studies were of ‘moderate’ quality and the remaining two were rated ‘good’ quality. Issues with similar samples, a tendency towards young, educated women within the IPV data, and small samples suggest caution is to be used when interpreting their results. The reliance on written measures and the absence of an interpreter or translation of materials in some studies further complicates the results. All types of abuse were found to be more prevalent within the deaf and hard of hearing population compared to the hearing population.  相似文献

This article seeks to examine the potential impact of the vote to leave the European Union (EU) in the UK referendum in June 2016, together with changes to professional training, notably the imposition of a new Solicitors Qualifying Examination (SQE) from 2019/20, on the teaching of EU law in law degrees in England and Wales. The history of the qualifying law degree (QLD) and the place of the EU law core module within it are explained. The likely continuing effect of EU law in the English Legal System is summarised, and the reduction in EU law content in the requirements for professional training as compared with that customary on a QLD is noted. In the light of these apparent threats to the EU law module, possibilities are explored for rethinking approaches to teaching law which would reinvigorate the significance of EU law in law degrees which may well undergo redesign in the light of the changes considered here.  相似文献

A curtain-raiser by the curator of the Exhibition of Antiquities from Afghanistan, which opens at the British Museum on 3 March 2011. The exhibits come from the National Museum in Kabul and show the richness and extent of trade in ancient times through and with Afghanistan. They are from excavations at a number of sites, including Begram, Tilla Tepe and Ai Khanum.  相似文献

The African National Congress, as an entity distinct from government, served during the 1994–2008 period as an independent forum for debate about South Africa's foreign policy, particularly in the National Executive Committee's Subcommittee on International Relations. This debate retained the oligarchic character of the movement in exile, with few voices – Thabo Mbeki's most prominent among them – dominating the discussion, inputs from subnational party structures almost non-existent, and dissenters expected to keep quiet publicly. That said, participants in these discussions largely dismissed characterisations of Mbeki as a dictator in the foreign policy debate, noting that the predominance of his views stemmed mostly from his strong argumentation and knowledge rather than bullying. Senior ANC leaders also claimed that limited interest in foreign policy, outside of national party structures, hindered efforts to broaden participation in foreign policy formulation.  相似文献
