The Widmark formula has been widely adopted in forensic applications to drink driving cases for the last 70 years. It is known that the amount of alcohol consumed and the body weight of the drinkers are important information for the estimation of blood alcohol concentration (BAC). However, the direct application of the Widmark factors derived from Caucasian to the calculation of BAC for the Chinese population often encounters serious challenges. Owing to this inherent weakness, a thorough analysis to determine the theoretical Widmark factors for the Chinese population, r(0) at the start of drinking and the practical factors, r(peak), at peak BAC was conducted. In the present study, other factors such as gender, stomach condition and other physiological conditions are taken into account. The determined theoretical Widmark factors, r(0,) for local Chinese male and female are 0.68 and 0.59 (with BAC in the units of weight/volume), respectively, demonstrating the applicability of the Widmark formula to the Chinese population. The practical factors at peak BAC, r(peak), were also determined to serve the forensic purpose of refuting the "hip-flask" defence in drink driving cases. Findings show that gender and stomach condition are the key factors that could statistically explain the variability of both r(0) and r(peak). 相似文献

Urine immunoassays are commonly used as a rapid screen for drugs of abuse in emergency room, hospital, clinic, and forensic settings. The authors were concerned whether or not a negative screen of the urine for opiates was of significance and indicative that analysis of blood for opiates was not necessary. Specifically, we wished to determine whether a negative test for opiates by immunoassay absolutely rules out an acute overdose, and if not, what percentage of cases with negative results have opiates in the blood. A retrospective analysis was performed using the toxicology results for cases ruled an acute narcotic overdose at the Bexar County Medical Examiner's Office between 1998 and 2003. One hundred eighty-three cases met the criteria for the study. A false-negative rate of approximately 15% was found using an immunoassay as compared with blood analysis for narcotics. The authors feel that while this rate may be acceptable in a clinical setting, it is unacceptable in a forensic setting. 相似文献

This article examines some social scientific issues relating to the operation and evaluation of crime prevention through mass media programs. It is argued that the efficacy of such programs is dependent upon the successful application of several empirically based communication principles. In addition, the attempt is made to analyze several general problems concerning the meaning and measurement of program success. Issues relating to both the operation and the evaluation of crime prevention through mass media programs are discussed in terms of their practical implications for public policy. 相似文献

This research examines in detail the structure of the issue public for health care reform, drawing from extensive, nationally representative survey data tapping general attentiveness to news and public affairs, specific interests in health care issues, and motivations (e.g., personal health and financial conditions) to follow health care reform issues. We furthermore adopt a multi-dimensional approach to defining the contours of the issue public for health care policy, separately studying its cognitive, affective, and behavioral underpinnings. Results indicate only weak interconnections across these dimensions—measured through health care knowledge, holding strong opinions on health care issues, and participation in health-related political activities, respectively—and somewhat different structural and motivational patterns underlying each. Theoretical, conceptual and methodological implications of these findings are discussed.Vincent Price and Joseph N.

The international donor community continues to emphasise country-led development strategies designed to equitably engage public and civil society agents in managing development assistance. Similarly donors who fund Western NGOs to implement development programmes on their behalf in recipient countries are increasingly pushing for cost-effective programme implementation that actively engages local actors. This article proposes an alternative theoretically grounded model for individual capacity strengthening to responsive and mission-driven Western NGOs that claim to be committed to ideals of capacity strengthening and indigenisation of programme leadership. 相似文献

France lags behind most other Western countries in its degree of ethnic representation, despite the longstanding presence of non-Western minorities in the country. French politicians and the public usually justify this situation by arguing that there are no such things as ethnic minorities in France, and therefore no particular ‘ethnic minority’ interests. Consequently, there is no need to be concerned about ethnic representation; class representation is enough. More recently, attention has centred on the presence of Islam. This frame biases political attention to religious issues related to ethnic minorities, leaving aside major problems such as racial discrimination. In contrast, this article argues that France is very similar to America when it comes to ethnic politics, particularly when analysing the political orientations of non-Western minorities. Without a proper voice to articulate their claims, ethnic minorities see their interests neglected in favour of other issues. 相似文献

This article draws on Pierre Bourdieu's sociology to explain how a lack of fit between a repertoire of bodily practices accumulated through history, on the one hand, (here, Russian habitus) and the field in which it is employed, on the other, (here, diplomacy) can take shape in world politics. Such “hysteresis” provides a longue durée reading that challenges both the realist idea that similar outcomes are due to invariant structures and the constructivist idea that structures “socialize” states. Social stability stems from agency, more specifically, from habitus. Our empirical examples are breaking points in Russian relations with neighbors: the Rus’ and the Eurasian steppe empires (ca. 800–1500), Muscovy's diplomatic interactions with Europe, and Russia's bid to join European international society and situation during the twentieth century. In each case, Moscow's relentless quest for equal status prompted quixotic practices that were often dismissed by Western countries and hampered the security of both parties. 相似文献
