The operation of a motor vehicle requires the integrity of sensory, motor, and intellectual faculties. Impairment of these faculties following the consumption of alcohol has been studied extensively through laboratory, closed‐course and on‐road driving, and epidemiological studies. The scientific literature was reviewed critically, with a focus on low‐to‐moderate blood alcohol concentrations (BAC ≤ 0.100%), to identify the most reliable determinants of alcohol‐impaired driving. Variables such as age, gender, driving skill, and tolerance were shown to have limited impact on impairment. It was concluded the most relevant variables are BAC and complexity of the driving task. The scientific literature provides a high degree of confidence to support the conclusion that a BAC of 0.050% impairs faculties required in the operation of a motor vehicle. Whether impairment is apparent depends upon the complexity of the driving task, which applies to both study design and actual driving.  相似文献

The business improvement district (BID) is a popular economic development and urban revitalization model in which local property and business owners must pay an assessment tax that funds supplementary services, including private security. BIDs constitute a controversial form of urban revitalization to some because they privatize economic development and public safety efforts in public space. This study examines whether BIDs provide tangible benefits beyond their immediate boundaries to local residents in the form of reduced violence among adolescents. The empirical analysis advances an existing literature dominated by evaluation studies by introducing a theoretically driven dataset with rich information on individual and neighborhood level variables. The analysis compares violent victimization among youths living in BID neighborhoods with those in similarly situated non‐BID neighborhoods. We find no effect of BIDs on violence. However, we do find that youth violence is strongly correlated with neighborhood collective efficacy and family‐related attributes of social control. In conclusion, we argue that BIDs may be an agent of crime reduction, but this benefit is likely concentrated only in their immediate boundaries and does not extend to youths living in surrounding neighborhoods.  相似文献

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high‐performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37°C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7°C, but degraded significantly in inoculated blood at 20 and 37°C. Complete loss occurred within 2 days when incubated at 37°C. The benzisoxazole‐cleaved degradation products for both drugs were identified as 2‐hydroxybenzoyl‐risperidone and 2‐hydroxybenzoyl‐paliperidone utilizing liquid chromatography quadrupole‐time‐of‐flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ.  相似文献

This paper describes a method for determining the density of contact trace objects with magnetic levitation (MagLev). MagLev measurements accurately determine the density (±0.0002 g/cm3) of a diamagnetic object and are compatible with objects that are nonuniform in shape and size. The MagLev device (composed of two permanent magnets with like poles facing) and the method described provide a means of accurately determining the density of trace objects. This method is inexpensive, rapid, and verifiable and provides numerical values—independent of the specific apparatus or analyst—that correspond to the absolute density of the sample that may be entered into a searchable database. We discuss the feasibility of MagLev as a possible means of characterizing forensic‐related evidence and demonstrate the ability of MagLev to (i) determine the density of samples of glitter and gunpowder, (ii) separate glitter particles of different densities, and (iii) determine the density of a glitter sample that was removed from a complex sample matrix.  相似文献

Pressure in the 1970's to reform the sentencing process can be attributed to a change in perceived public sentiment regarding the utility of treatment and to the belief that sentencing disparity was a severe problem in the sentencing process. Primary reform occurred in the federal judicial system with the development and implementation of rigorous sentencing guidelines. An evaluation of sentencing patterns for one federal judicial district indicates that sentencing disparity was not severe. Most federal offenders are relatively mild and consistently receive relatively mild sentences.  相似文献

Levels of citizen estrangement from government in the United States have risen rather consistently since the late 1960s and have reached all‐time highs in recent years. Evidence is accumulating in political science research to suggest that public administrative theory may have contributed to this trend since the Progressive Era in the early 1900s. The authors develop this thesis by arguing that administrative theory in the United States has persistently portrayed public managers as “bridge builders” who link an expertise‐challenged citizenry to government in ways that emphasize bureaucratic over democratic administration. Moreover, despite claims of yet another “new” paradigmatic shift for the field, collaborative governance scholarship to date exhibits similar tendencies. To support this argument, the authors assess the common citizen‐marginalizing tendencies of three sets of administrative reforms in American public administration: the progressive, associationalist, and polycentric heritages. They offer counterarguments to this thesis and call for critical self‐reflection by the field and a more empirically robust research agenda on this topic.  相似文献
