The Effect of Alcohol‐Based Hand Sanitizer Vapors on Evidential Breath Alcohol Test Results 下载免费PDF全文
This study was undertaken to determine if the application of alcohol‐based hand sanitizers (ABHSs) to the hands of a breath test operator will affect the results obtained on evidential breath alcohol instruments (EBTs). This study obtained breath samples on three different EBTs immediately after application of either gel or foam ABHS to the operator's hands. A small, but significant, number of initial analyses (13 of 130, 10%) resulted in positive breath alcohol concentrations, while 41 samples (31.5%) resulted in a status code. These status codes were caused by ethanol vapors either in the room air or their inhalation by the subject, thereby causing a mouth alcohol effect. Replicate subject samples did not yield any consecutive positive numeric results. As ABHS application can cause a transitory mouth alcohol effect via inhalation of ABHS vapors, EBT operators should forego the use of ABHS in the 15 min preceding subject testing. 相似文献

Three experiments investigated the role of stereotypic and nonstereotypic criteria in judgments of political candidates. The effects of physical attractiveness, political party, and stands on specific issues on both absolute and comparative judgments of political candidates were examined to evaluate three hypotheses about stereotype and attribute use. In the absence of other information, candidates' physical attractiveness (conveyed through photographs) had a substantial influence on subjects' global evaluations of them and inferences of both their personal qualities and their political ideology. When other information about the candidates' party membership and stands on specific issues was available, however, the candidates' attractiveness had no effect on the evaluations of them. When subjects made judgments of only one candidate, subjects relied exclusively on the candidate's voting record. When subjects were asked to make comparative judgments of two candidates, however, they based their judgments on each candidate's party membership and not on their respective voting records. Implications of these results for the processes that underlie political judgments and decisions are evaluated. 相似文献

International research into democracy has uncovered severe changes in patterns of political engagement and participation. Even political institutions such as political parties and voluntary organisations have undergone major alterations. Scandinavian democracies hitherto have been regarded as exceptionally stable and strong due to their homogenous qualities of mass-based class politics, strong political parties, high degree of associationalism, peaceful labour market relations and developed welfare policies. However, three official democratic audits recently revealed that Scandinavian democracies have also been severely affected by both exogenous and endogenous constraints. In addition, Scandinavian democracies appear to be diverging heterogeneously from the assumed 'pan-Scandinavian' model. This article examines whether the distinctive country characteristics uncovered by the commissions can be traced among young adults. Three dimensions of attitudes of young adults are analysed – political trust, political engagement and political equality – using survey data obtained from students in academic programmes at the upper secondary level in Denmark, Norway and Sweden in 2000. Generally, the results not only confirm a country diversity that threatens to jeopardise Scandinavian homogeneity, since the Danes stand out as superior in most measures of political participation, but also, from an international perspective, young Scandinavians cannot be characterised as the most politically interested or participative between elections or even as the most multiculturally tolerant among today's youth. 相似文献

Nonprofit organizations play a critical role in U.S. housing policy, a role typically justified by the claim that their housing investments produce significant neighbor‐hood spillover benefits. However, little work has actually been done to measure these impacts on neighborhoods. This paper compares the neighborhood spillover effects of city‐supported rehabilitation of rental housing undertaken by nonprofit and for‐profit developers, using data from New York City. To measure these benefits, we use increases in neighboring property values, estimated from a difference‐in‐difference specification of a hedonic regression model. We study the impacts of about 43,000 units of city‐supported housing completed during the 1980s and 1990s, and our sample of property transactions includes nearly 300,000 individual sales. We find that both nonprofit and for‐profit projects generate significant, positive spillover effects. This finding in itself is significant, given the widespread skepticism about the impact of subsidized housing on neighborhoods. We also find some differences across sectors. First, the impact of nonprofit housing remains stable over time, whereas the effect of for‐profit housing declines slightly with time. Second, while large for‐profit and nonprofit developments deliver similar benefits, in the case of small projects, for‐profit developments generate greater impacts than their nonprofit counterparts. These differences are consistent with theoretical predictions. In particular, in the presence of information asymmetries with respect to housing quality, the non‐distribution constraint should lead nonprofits to invest more than for‐profits in developing and maintaining features that benefit the broader community. Meanwhile, the fact that scale makes a difference to nonprofit impacts may reflect the capacity constraints often faced by smaller nonprofits. ©2006 by the Association for Public Policy Analysis and Management 相似文献
