A simple, quick, selective, sensitive, and effective field-friendly method capable of being used by nonexperts has been developed for detecting mitragynine in Mitragyna speciosa (kratom) using surface-enhanced Raman spectroscopy (SERS). Over 100 samples and blanks (known to be either positive or negative for the presence of mitragynine) were examined in duplicate using five identical handheld Raman spectrometers, which provided a data set of over 1,000 examinations. Based on the results of these analyses, the method yielded a true-positive rate of 99.3%, a true-negative rate of 97.9%, a false-positive rate of 2.1%, and a false-negative rate of 0.7%. The average minimum detectable concentration (Cm) of mitragynine that reproducibly yielded a match for one of the library spectra on all five instruments was determined to be 342 ng/mL (ppb). This Cm value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the Cm value achieved was well below typical mitragynine concentrations in kratom (1.3–2.3%). The method is ideal (i) for prioritizing samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify mitragynine and (ii) for field use at international mail facility (IMF) satellite laboratories to help interdict kratom and prevent this dangerous product from reaching the U.S. supply chain.  相似文献

Abstract

This study applies moral foundations theory to capital juror decision making. We hypothesized that binding moral foundations would predict death qualification and punitive sentencing decisions, whereas individualizing moral foundations would be associated with juror disqualification and a leniency effect. Additionally, we considered whether moral foundations can explain differences in death penalty application between conservatives and liberals. Respondents from two independent samples participated in a mock-juror task in which the circumstances of a hypothetical defendant’s case varied. Results revealed moral foundations were strong predictors of death qualification. The binding and individualizing foundations were related to sentencing decisions in the expected ways. Supporting our contention that moral foundations operate differently across different types of cases, heterogeneity in the effects of moral foundations was observed. Finally, we found support for the hypothesis that the relationship between sentencing decisions and conservatism would be attenuated by moral foundations.  相似文献

Qualitative interviews with one hundred defendants in Dutch criminal cases examine whether perceived procedural justice is a relevant concern for defendants, and, if so, which procedural justice components they refer to. The study provides a point of epistemological departure from the quantitative studies dominating the field, as it assessed which components of procedural justice (if any) respondents put forward themselves rather than asking about predetermined procedural justice components. The large majority of respondents mentioned procedural justice issues themselves, and six components were at the core of their procedural justice perceptions: (1) information on which decisions are based, (2) interpersonal treatment, (3) due consideration, (4) neutrality, (5) voice, and (6) accuracy. Although these procedural justice components largely correspond with the literature, respondents thus mentioned some components more often, and others less often, than the literature would suggest. In particular, neutrality plays an important role in the Dutch legal context examined here.  相似文献

In the last 50 years Chinese arbitration law and practices has made significant contributions to the international commercial arbitration and strides to manage the rapidly increasing caseload associated with a period of amazing growth in economic interactions between Chinese and non-Chinese parties. In the global economy there are rooms for further improvement. The paper proposed some ideas on reforming the Chinese arbitration law and practices on the arbitration system regarding the ad hoc arbitration, panel system and tribunal jurisdiction, interim measures of protection, as well as standards for the judicial review on the arbitral awards.  相似文献

After the Agreement on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) came into operation in 1995 developing countries have found themselves in a process of continual negotiation over intellectual property rights and access to medicines. These negotiations have taken place in the World Trade Organization and in the context of free trade agreements. The paper suggests that the only real win for developing countries has been the Doha Declaration on the TRIPS Agreement and Public Health in 2001. What have been the lessons for developing countries in a decade of negotiations over access to medicines? Drawing on themes of rule complexity and regulatory ritualism the paper discusses four key lessons for developing countries. It concludes by arguing that developing countries will do better if they adopt a networked governance approach to negotiation rather than continuing to rely on traditional coalition formation.  相似文献

This paper explores the multi-layered representations of violence and crime in the recent Hollywood film Gangs of New York [Scorcese (2003) Miramax]. We use our exploration of this film to suggest that popular culture, even through its most mainstream products, can be seen as a critical criminological space where alternative views of law, crime and the state are made available. Rather than understanding Hollywood movies simply as vehicles for disseminating conventional mores, we suggest that they can furnish critical (and complex) points of view on law and crime and that the project of a critical criminology can be strengthened by engaging more forthrightly with these ubiquitous cultural forms.  相似文献

  East Asia, including Northeast Asia and Southeast Asia, has developed tightly-linked production/distribution networks through globalizing corporate activities. The vertical chain of production in East Asia has been even more sophisticated than economic integration in East Europe or Latin America. However, the political environment of East Asia for trade and investment has been far from borderless. The integration effort at the policy level has been very much limited so far, due to the historical background as well as geopolitics surrounding East Asia. The Asian currency/financial crisis provided these countries a historical turning point. After the burst of the crisis, East Asians realized that they have to take care of themselves in their difficulties, not depending on outside forces. A natural choice for them was to step into the realm of regionalism. In 1998, Japan and Korea officially announced that they would discard the long-lasting GATT/WTO-only approach and adapt the multi-layered approach, including both regionalism and multilateralism. The ultimate goal of regionalism would be a region-wide integration including ASEAN+3. As a steppingstone, Japan signed the Japan-Singapore Economic Partnership Agreement (JSEPA) in January 2002. In a parallel move, the ASEAN and China Leaders announced in November 2001 the establishment of an ASEAN-China Free Trade Area (ACFTA) within 10 years. This article will follow up the most recent advancement of regional institutional building in East Asia with the emphasis on peculiar characteristics of economic integration in the region and discuss its implications for Asia-Europe relations. This paper is heavily drawn from Kimura (2002, 2003).  相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.
