This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain. 相似文献

Current research suggests that a husband's substance abuse is correlated with severity of physical abuse and the woman's decision to leave a violent situation. Often, only the battered woman's report of abuse is available. This study compares women's reports of their partners' substance use/abuse with their partners' report using a brief measure of polydrug and alcohol abuse, the Substance Abuse Subtle Screening Inventory (SASSI) and the Conflict Tactics Scale (CTS). Data were analyzed for 25 recovery couples and 25 nonrecovery couples. The correlations for all 50 couples between the male's reported use and the female's report of her partner's use on the SASSI and the CTS were significant on all but one of the CTS scales. They ranged on SASSI from .73 to .33 and from .31 to .06 on the CTS. This suggests that the SASSI and possibly the CTS could be used as valuable tools for assessing women's reports of their partner's substance use/abuse. 相似文献

Modern capital jurisprudence places special significance on judicial instructions to guide the discretion of the capital jury in reaching a penalty phase decision. Yet, previous social science research has raised doubts about the extent to which judicial instructions are generally understood by jurors and questioned their utility in producing intended effects. The present study measured the comprehension of the capital sentencing instruction employed in California. Data suggest widespread inability to define accurately the central concepts of aggravation and mitigation in use in virtually every state that currently has a death penalty statute, as well as the inability to distinguish properly the sentencing significance of the enumerated factors jurors are directed to use in reaching their life and death verdicts. In addition, an inordinate focus on the circumstances of the crime—to the exclusion of other potentially important factors—was identified, as well as special problems in comprehending the crucial concept of mitigation in constitutionally required ways.We would like to thank Suzanne Ban, Cori Nardello, and Maryanne Tagavilla for assistance in transcribing and content-analyzing the data. 相似文献

To understand the impact of reunification upon Germans, we must make before and after comparisons across time, and also across central Europe. The first section shows that from the perspective of comparative Communist regimes, east Germans have been doubly advantaged, in former times because of belonging to a relatively prosperous part of the Soviet bloc and since reunification as subjects of a ‘ready‐made state’ with democracy and a wealthy social market economy. Analysis in the second section of the impact of reunification on west Germans shows that a significant proportion feel less satisfied than before, whereas the opposite is the case for east Germans. The third section introduces comparisons with Austria. Like the Federal Republic, it has enjoyed the advantages of democracy and a market economy, but without the trauma of division and reunification. 相似文献

The main objective of this study is to provide estimates of price and income elasticities of demand for tea in order to explain the growth in tea consumption over the period 1874–1938. Numerous other factors, both economic and social, may contribute to changing patterns of consumption. Indeed, such factors as demographic and organisational changes and different social habits may exert an influence on price and income elasticities. A subsidiary aim of this study is to examine the influence of these factors on the differences in income and price elasticities in demand for tea over various sub‐periods between 1874 and 1938. 相似文献

This article analyzes civil society participation in the free trade debate by focusing on networks that opposed the Central American Free Trade Agreement (CAFTA) in El Salvador. Drawing on documents, direct observation, and semistructured interviews with civil society leaders, two kinds of opposition coalitions are identified. "Critic negotiators," emphasizing active engagement and policy research, used the limited participation space opened by authorities to push for reform. "Transgressive resisters," repudiating the formal consultation process, deployed confrontational tactics and posed more fundamental challenges. This work uses social movement theory to explore coalition resource mobilization, the role of movement entrepreneurs, strategic decisionmaking, mechanisms linking local and transnational activists, and the dynamics of intramovement competition. 相似文献
