This article describes the isolation and structural elucidation of three compounds produced during the synthesis of methylamphetamine by the so‐called “Emde” procedure. The “Emde” procedure involves the preparation of the intermediate chloropseudoephedrine or chloroephedrine from ephedrine or pseudoephedrine, respectively. The intermediates are then reduced to methylamphetamine with hydrogen under pressure in the presence of a catalyst. The by‐product compounds were isolated from methylamphetamine by column chromatography and liquid chromatography (LC). Proton nuclear magnetic resonance spectroscopy (1H NMR), carbon nuclear magnetic resonance spectroscopy (13C NMR), and nanospray quadrupole‐time of flight‐mass spectrometry (Q‐TOF‐MS) were used to identify them as two stereoisomers of the compound N, N′‐dimethyl‐3,4‐diphenylhexane‐2,5‐diamine and N‐methyl‐1‐{4‐[2‐(methylamino)propyl]phenyl}‐1‐phenylpropan‐2‐amine.  相似文献

There is a paradox within United States immigration policy. Immigration policy separates families while also promising family unity. We address this paradox by arguing that state actors use “family” as a state-granted status. The state perceives some households as families and grants them benefits, while forcing other households to live as legal strangers. Individuals may form familial relationships, but the privileges and status of family are controlled by state actors and institutions. When state actors separate low-wage immigrant worker families, the state's family-status-granting power keeps these workers and their families in a state of “deportability”-a legally ambiguous limbo-satiating business interests and securing a captive low-wage workforce. Lacking legal legitimacy, but financially and socially tied to their families and communities in the U.S., these immigrants have few options but to accept off-the-radar work and to raise their children while living as “outlaws.”  相似文献

This article examines the application of 'triangulation' to the use of elite interviewing in political science, with specific reference to the study of the intelligence and security services. It is argued that the problems involved in using elite interviews in security and intelligence studies are no different than in other areas of political science, but simply more pronounced. It is further argued that these problems can be most effectively addressed in terms of the sociological 'triangulation' strategy of multi-methodological research. The article concludes that this approach is, moreover, generally applicable to political studies at large.  相似文献

Jokes can only properly be studied comparatively and in relation to differences in the social structure and culture of the two or more countries where they are told. This is best done by looking at how joke cycles, large aggregates of jokes, change as they move between two countries that have the same language. American stupidity jokes about Poles and blondes changed significantly when they came to be told in Britain about the Irish and about Essex Girls, even though the same themes were employed. The changes can be related to the greater British willingness openly to acknowledge and to joke about class distinctions and to their not sharing the American obsession with hygiene, purity and physical perfection. American lawyer jokes are told in Britain not as local jokes about lawyers but as specifically American jokes about American lawyers. In Britain power and decision making lie with Parliament not judges and lawyers, a utilitarian not a rights political philosophy prevails and there is no sacred written constitution. In America there is far more respect for ‘the law’ and lawyers can not possibly live up to these expectations. In Britain to be a lawyer is just one more job and the lawyers do it honestly and unremarkably.  相似文献

The ABO grouping results from approx. 1000 seminal stains have been collected and analysed. Most of the stains came from rape cases where the ABO and secretor status of both complainant and suspect were known. The results of the survey provided information concerning the usefulness of elution and inhibition as methods of body fluid grouping, the relative strengths of reaction of the A, B and H antigens in body fluids and the interpretation of the ABH reactions of body fluid stains.  相似文献

This article argues that neoliberalism with its pervasive patriarchy and co-option of feminism, renders women tacitly complicit in gendered pay inequalities. We show that in New Zealand, one of the world’s most neoliberal nations, women who might precisely be best equipped to argue for equal pay – engineers – do not do so because neoliberalism makes many feel responsible for, and accepting of, their lower salaries. In interviews and focus groups, many women engineers talk of deserving less pay than men because of their ‘choices’, their ‘personality’ and their lack of ‘responsibility’. In a disempowering environment, some women show agency by disavowing gender as a reason for the pay gap. Such narratives of individualized shortcomings reduce hope of collective action that might uncover and dismantle the systemic causes of pay inequity, which are not due to a woman’s choice or personality but rather what we frame as the neoliberal chimera.  相似文献

Despite change in the aims, institutions and informal diplomacy of ASEAN since 1997, the formal diplomatic code of conduct remains locked in a traditionalist mode first outlined in the 1970s. Existing approaches from mainstream International Relations theorising are unable to adequately explain this continuity and change. The recent ‘practice turn’ in theorising offers distinct explanatory advantage, which this article illustrates by arguing that the formation of an ‘ASEAN rationality’ between 1967 and 1997 fundamentally curtailed the ability of regional diplomats to revise ASEAN post 1997, resulting in the coexistence of new and old norms in ASEAN's organisation design.  相似文献
