The use of license plate recognition technology (LPR) by police is becoming increasingly common. LPR may be used for many purposes, ranging from stolen vehicle enforcement to more complex surveillance and predictive functions. Existing research does not examine community support for this technology, despite its potential to impact police legitimacy. Results from the first community LPR survey are presented and multinomial logistic regression models of citizen support for the technology are developed. Regression results suggest that a number of factors significantly predict citizen support for LPR use, including increased trust in police and the belief that LPR information is public information. 相似文献

Expensive anti-cancer drugs expose controversy underlying the process for resource allocation decisions, and intermittently result in marked publicity, emotive discussions about access to novel and expensive treatments, and political involvement which may override existing processes. This column outlines the methods of determining whether or not a treatment is considered appropriate to fund, and focuses upon the evidence of patient and doctor wishes. The existing research illustrates the complexity of patient and oncologist decision-making when these drugs are to be considered. Past litigation to obtain access to expensive treatments is discussed, along with the interactions between patients, pharmaceutical companies, health services and oncologists. This evolving field is being transformed by developments in molecular biology enabling targeted drugs, and amply demonstrates the complexity of funding decisions and how expensive treatments are considered by a range of stakeholders. 相似文献

Sudden death in association with minor or otherwise insignificant head injury is increasingly being recognised in the forensic medical literature. While the exact mechanism of the cardiorespiratory arrest that appears to occur in these cases is unclear, a number of mechanisms have been postulated. Animal studies have provided evidence that alcohol can be associated with an increased period of apnoea following minor physical brain injury and cardiac changes have also been identified. The limited information in the community about the risk of alcohol in association with minor head injury causing death may be relevant in homicide cases where this issue is raised. 相似文献
