A simple and reliable previously reported extraction procedure has been extended to the analysis of a wide range of basic and neutral drugs in postmortem blood and other tissues. The method employs 200 microliters of blood treated with water and ammonia and extracted with diethyl ether. The concentrated extract is generally sufficiently clean for direct analysis by gas chromatography and high pressure liquid chromatography. Recovery, precision and linearity data are presented for selected drugs.  相似文献

Through what mechanism do interest groups shape public opinion on concrete policies? In this article, three hypotheses are proposed that distinguish between the effect of the arguments conveyed by interest groups and the effect of interest groups as source cues. Two survey experiments on the proposed Transatlantic Trade and Investment Partnership (TIPP) and the 2015 Paris Agreement on climate change allow the testing of these hypotheses. The resulting evidence from several countries shows that, with respect to interest groups’ attempts at shaping public opinion, arguments matter more than their sources. This is so even when accounting for people's trust in the interest groups that serve as source cues and for people's level of information about a policy. The finding that interest groups affect public opinion via arguments rather than as source cues has implications for the literature on elite influence on public opinion and the normative evaluation of interest group activities.  相似文献

While research suggests that public service motivation may be a dynamic trait in individuals, particularly early in their careers, other recent research has found that PSM may be relatively stable upon entry into the workforce (Vogel and Kroll 2016). To identify more precisely the decision point among individuals considering a public service career, the present study uses the antecedents of public service motivation framework (Perry 1997) to predict participation in AmeriCorps, a voluntary national service program in the United States. Findings reveal that antecedent conditions of PSM, including the prevalence of seeing family members and mentors help others as well as participation in student government, predict whether an individual will join an AmeriCorps programs. Many of these self-reported motivations support the argument that people attracted to public service hold strong other-regarding values. These findings suggest that human resources managers would be wise to consider these antecedent conditions to public service motivation when identifying pools of talent for recruiting and selecting prospective employees.  相似文献

Fiscal contrition refers to the phenomenon of policy-makers becoming aware of the social costs of fines and fees, recognizing a need to reduce those costs, and taking action to do so. In order to reveal the occurrence of fiscal contrition, this analysis examines detailed budget data from three U.S. counties. Findings indicate a dominance of predatory over punitive monetary sanctions in county budgets. That is, fines and fees that extract revenue from a justice-involved population are more common than those with social control objectives. The analysis also reveals patterns and nuances in fine and fee usage and the revenue they produce, which illuminates pathways for reducing reliance on fine and fee revenue. This approach provides useful context for the burgeoning scholarship focused on the role of monetary sanctions in fueling social inequities.  相似文献
