Cellulose and lactose are the most frequently used excipients in illicit ecstasy production. The aim of this project was to use near infrared reflectance spectroscopy (NIRS) for the determination of the different chemical forms of these two substances, as well as for the differentiation of their origin (producer). It was possible to distinguish between the different chemical forms of both compounds, as well as between their origins (producers), although within limits. Furthermore, the possibilities to apply NIR for the analysis of substances such as found in illicit tablets were studied. First, a few cellulose and lactose samples were chosen to make mixtures with amphetamine at three degrees of purity (5, 10 and 15%), in order to study the resulting changes in the spectra as well as to simultaneously quantify amphetamine and identify the excipient. A PLS2 model could be build to predict concentrations and excipient. Secondarily, the technique was to be applied to real ecstasy tablets. About 40 ecstasy seizures were analysed with the aim to determine the excipient and to check them against each other. Identification of the excipients was not always obvious, especially when more than one excipient were present. However, a comparison between tablets appeared to give groups of similar samples. NIR analysis results in spectra representing the tablet blend as a whole taking into account all absorbing compounds. Although NIRS seems to be an appropriate method for ecstasy profiling, little is known about intra- and intervariability of compression batches.  相似文献

Bryen, Ari Z. 2013. Violence in Roman Egypt: A Study in Legal Interpretation . Philadelphia, PA: University of Pennsylvania Press. Pp. 376. $75.00 cloth; $75.00 eBook. This essay examines the linguistic anthropological themes emergent in Violence in Roman Egypt (2013). Viewing law as a discourse, it explores how language is constitutive of law and is the primary modality of acting upon, and enacting the world(s) that it shapes, giving meaning to the lives of people who engage each other in and through it. Violence petitions in second‐century Egypt are a fundamental mode of sense making and problem solving, calling on legal authorities to interpret claims of iniuria, or legal battery, into a language that they understand and remedy. In doing so, law changes the discourse of violence, specifically, and social life, more broadly.  相似文献

Theories of participation and non-participation are largely unable to capture and distinguish anti-system behavior, which ranges from deliberate silence to political violence. To better understand and measure these diverse forms of citizen participation, and to distinguish these from forms of alienation and marginalization, this article builds a new model of anti-system behavior in a way that facilitates the development of empirically observable variables and hypotheses. To do so, I draw upon sociological approaches to alienation – which examine intensities of rebellion and contestation – and combine them with the standard political scientific approach – which examines intensities of engagement based on resources. The problem, I argue, is that each approach only partially explains the motivations behind aberrant political behavior in modern democratic systems; they are in fact two sides of the same coin. I consider three cases of apparent silent citizenship: Muslims in Western Europe, Roma in Eastern Europe, and white working-class people in North America and Europe.  相似文献
