Abstract: The frequency and characteristics of suicide by cop cases (SBC) among a large (n = 707) nonrandom sample of North American officer-involved shootings (OIS) were investigated. “Suicide by cop” is when a subject engages in behavior which poses an apparent risk of serious injury or death, with the intent to precipitate the use of deadly force by law enforcement against the subject. Thirty-six percent of the OIS in this sample were found to be SBC with high interrater agreement (intraclass correlation coefficient = 0.93) for category classification. SBC cases were more likely to result in the death or injury of the subjects than regular OIS cases. Most SBC cases were spontaneous, but had clear verbal and behavioral indicators that occurred prior to, and during the event. Findings confirm the trend detected in earlier research that there was a growing incidence of SBC among OIS. SBC individuals had a high likelihood of possessing a weapon (80%), which was a firearm 60% of the time. Half of those with a firearm discharged it at the police during the encounter. Nineteen percent simulated weapon possession to accomplish their suicidal intent. Other findings highlight the histories and commonalities in this high risk group.  相似文献

Without high‐quality translation of online information about government support and services, refugees and migrants from culturally and linguistically diverse backgrounds in Australia experience a major barrier to improved health, employment, education and social outcomes. Recent advances in the ability of Google Translate, Skype Translator and other forms of machine translation that use artificial intelligence can help translate government information to better support refugees and migrants but they bring the risk of ineffective communication, and exclusion from services that could positively impact on settlement experiences and daily life. Evidence suggests that government agencies are likely to be using human translators for most translation work, but the degree to which any form of information technology is used, how it may be best applied and the associated effects are not known. This study systematically reviewed the peer‐reviewed and grey literature to determine effective ways of using information technology for translating government information to refugees and migrants from culturally and linguistically diverse backgrounds in Australia. Included studies were analysed to identify techniques and other characteristics of translation, information technology and language support more broadly, and outcomes on education, health, social and other refugee and migrant experiences relating to translated information. Our review found a small evidence base featuring studies with strong evaluation demonstrating effective forms of ‘language support’ for refugees and migrants from culturally and linguistically diverse backgrounds in Australia in a broad sense. However, there is a major gap in knowledge that is contributing to barriers in the use of online government information in Australia. In particular, there is an absence of evidence demonstrating what is effective in the use of machine translation with artificial intelligence, websites and other kinds of information technology for translating government information with refugees and migrants from culturally and linguistically diverse backgrounds. The oversight risks further excluding already marginalised groups from services and support. This paper makes a number of suggestions practitioners can take to address the issue and guidelines for future research.  相似文献

There are two main arguments in this article. First, if wages and employment are to be used as indicators of changing levels of rural poverty they need to be complemented by micro and meso level studies of how increases or declines in wages and employment are distributed among individuals and households. Secondly, if the nature of the relationship between employer and labourer is to be understood, aggregates such as ‘casual’ labour need to be unravelled. Evidence from a study of two small localities in rural West Bengal between 1991 and 1993 suggests that the poorest workers receive the lowest remuneration across a range of informal contracts, including daily time‐rate, piece rate, seasonal beck‐and‐call and migrant labour arrangements. Levels of remuneration are also determined by locally specific ideologies of gender and social rank and by party politics.  相似文献

This article examines the environmental benefits arising from compliance with common law nuisance injunctions during the British industrial revolution. It argues, based on the outcomes of industrial nuisance actions involving allegations of serious air and river pollution, that many millions of pounds were invested by corporate polluters in designing and implementing clean technologies within the framework of the common law. Nuisance law was not an unqualified success in the field of environmental protection at this time, but overall the findings contribute to the on‐going critique of the nuisance law histories of Brenner and McLaren, which argue that various limitations of the common law are at the root of modern environmental problems. The discovery of historic practical measures of environmental protection through common law enforcement raises important conceptual, policy, and legal questions for today, and disciplinary questions regarding the rigour of realist legal scholarship concerning the historic performance of the law.  相似文献
