Abstract: A case is presented of a 39‐year‐old woman who suffered severe debilitation because of a hemorrhagic stroke in the context of substance abuse. The patient presented to the emergency room with rapidly diminishing mental status, hypertension, and vasoconstriction; her friends provided a history of ingestion of cocaine, 3,4‐methylenedioxymethamphetamine (MDMA), and 2C‐I, a novel designer amine. A multi‐targeted LC‐MS/MS method for sympathomimetic amines and related drugs in urine detected and quantified 2C‐I and MDA, while ruling out MDMA. The cause of the stroke was determined to be an underlying cerebrovascular abnormality called Moyamoya, secondary to substance abuse. In clinical laboratories, gas chromatography–mass spectrometry or liquid chromatography–tandem mass spectrometry (LC‐MS/MS) confirmation of a positive amphetamine immunoassay is usually directed only towards amphetamine, methamphetamine, MDMA and MDA. This report demonstrates the utility of testing for a wider menu of compounds using LC‐MS/MS in order to better characterize the prevalence and toxicities of novel amines such as 2C‐I. 相似文献

The effects of video games on children’s psychosocial development remain the focus of debate. At two timepoints, 1 year apart, 194 children (7.27–11.43 years old; male?=?98) reported their gaming frequency, and their tendencies to play violent video games, and to game (a) cooperatively and (b) competitively; likewise, parents reported their children’s psychosocial health. Gaming at time one was associated with increases in emotion problems. Violent gaming was not associated with psychosocial changes. Cooperative gaming was not associated with changes in prosocial behavior. Finally, competitive gaming was associated with decreases in prosocial behavior, but only among children who played video games with high frequency. Thus, gaming frequency was related to increases in internalizing but not externalizing, attention, or peer problems, violent gaming was not associated with increases in externalizing problems, and for children playing approximately 8?h or more per week, frequent competitive gaming may be a risk factor for decreasing prosocial behavior. We argue that replication is needed and that future research should better distinguish between different forms of gaming for more nuanced and generalizable insight. 相似文献

We analyse the marketing of ‘heirloom rices’ produced in the Cordillera mountains of northern Luzon, the Philippines, as the commodification of a historical ‘anti-commodity’. We contend that, historically, rice was produced for social, cultural and spiritual purposes but not primarily for sale or trade. The Ifugaos were able to sustain terraced wet-rice cultivation within a system of ‘escape agriculture’ because they were protected from Spanish interference by the friction of terrain and distance. ‘Heirloom rice’ is a boundary concept that enables social entrepreneurs to commodify traditional landraces. We analyse the implications for local rice production and conservation efforts. 相似文献

Models of voting behavior typically specify that all voters employ identical criteria to evaluate candidates. We argue that moderate voters weigh candidates’ policy/ideological positions far less than non-moderate voters, and we report analyses of survey data from the 2010 Cooperative Congressional Election Study that substantiate these arguments. Across a wide range of models and measurement strategies, we find consistent evidence that liberal and conservative voters are substantially more responsive to candidate ideology than more centrist voters. Simply put, moderate voters appear qualitatively different from liberals and conservatives, a finding that has important implications for candidate strategies and for political representation. 相似文献

Law and Critique - Conscience rests within the heart of equity, yet it is a manifestly nebulous and contradictory concept. In particular, equity has never been clear about exactly whose conscience... 相似文献

This article examines aspects of African culture seen as projects from an existentialist perspective and seeks to make a robust contribution to African studies and in particular interdisciplinary African studies. It offers a focus on the interiorisation of African cultural project-as-text as an upsurge of being; interiorisation(s) of being projects of African being and consciousness. This study on African subjectivity situates the African cultural constituency within a specific existentialist schematic: the African for itself in the form of cultural project-as-text, a reflective black consciousness, the black ‘I’ or African being-with-others in the form of cultural projects-as-texts, a self-reflective conscious of black consciousness, the black ‘we’-subject, ‘us’, and lastly African being-for-ourselves Black existentialist philosophy is predicated on the liberation of all black people from oppression. 相似文献

We discuss how the Registered Traveler (RT) program can enhance simultaneously aviation security and passenger convenience. We point out some of the potential weaknesses in the program from both a security and civil liberty perspective. The RT program is a public–private partnership between the Transportation Security Agency (TSA) and the private sector. As in any partnership between private enterprises and the public sector, there are tensions that must be monitored, managed, and resolved. We note that financial distress of a RT service provider will place increased pressure on TSA resources. We review the resources allocated by the public and private sectors and the natural tensions that exist between companies investing capital with the expectation of earning a market rate of return and an agency of the Department of Homeland Security, the TSA, with one of its responsibilities being to assure the safety and security of air travel. 相似文献
