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

This article discusses the impact of drought on poverty dynamics in the South Wollo area of northeastern Ethiopia. Using both survey and anthropological/qualitative data covering a six-year period, the paper assesses which households were able to hold on to assets and recover from the 1999–2000 drought and which were not. It suggests that while the incidence of poverty changed very little during 1997 to 2003 despite the occurrence of a major drought, the fortunes of the poorest improved, but not enough to keep them from poverty. The study concludes by asking how current policies affect patterns of poverty and inequality and what might be done to improve welfare in South Wollo. 相似文献

The notion of “counterinsurgency” (COIN) has for some years been the central concept driving military operations in Afghanistan, and before that, in Iraq. It constitutes the dominant idea influencing much current military planning of the major Western powers. This study questions the assumptions and relevance of the thinking behind counterinsurgency doctrine. It suggests that the ultimate effect of its dominance is to reduce the highly contingent nature of war to a list of techniques, the application of which are regarded as a sufficient precondition whenever states deem that they are confronted by conflicts that can be described as an “insurgency.” Such assumptions are both arbitrary and risk crowding out necessary, although by their nature very difficult, political judgments that are required for the effective construction and implementation of strategies that seek to ensure that the ends sought are proportional to the means employed. 相似文献

Bullying in secondary schools is a serious concern for educators and parents. The relationship between bullying and school climate has been identified and strategies to improve school climate are available. The importance of leadership in shaping school climate has been well documented. This exploratory study explores the role of leadership in implementing an approach to school climate change (positive behavior intervention and supports) in comprehensive Southwestern high schools participating in a federal school safety grant. Leadership involvement in the change process appears to be a key component leading to student-reported behavior change. Our findings suggest that although changes in school climate should lead to changes in bullying behaviors, the opposite is the case. Implications for practice and further research are discussed. 相似文献

Much work examines self-presentation styles; however, little work explores how people present themselves in traffic court. Utilizing observatory research, we aim to better understand differences in physical presentation and demeanor in traffic court. Further, judges that work in traffic court were interviewed to see how they understood the importance of presentation of self. Data indicate that most of those who appear in traffic court aim to present themselves professionally and behave with respect while in court. This appears to be a wise decision because judges tended to think that presentation of self was an important variable in their courtroom and how they evaluated cases. Still, differences in presentation of self appeared in the courtroom especially with regard to dress – extremely casual to orange jumpsuits. Finally, we argue that while modern defendants aim to present professionally the overall ‘professional’ presentation of self, even in the courtroom, is casual dress. 相似文献
