A simple and rapid method for the analysis of heroin seizures by micellar electrokinetic chromatography with short-end injection is described. Separations were performed using an uncoated fused silica capillary, 50 cm x 50 microm I.D. x 360 microm O.D. with an effective separation length of 8 cm. The system was run at 25 degrees C with an applied negative voltage of -25 kilovolts. Injection of each sample was for 2 s at -50 mbar. UV detection was employed with the wavelength set at 210 nm. The background electrolyte consisted of 85:15 (water:acetonitrile, v/v) containing final concentrations of 25 mM SDS and 15 mM sodium borate, pH 9.5. Samples and standards were prepared in 0.1% v/v acetic acid and diluted in the run buffer containing 1 mg/ml of N,N-dimethyl-5-methoxytryptamine as an internal standard. Under these conditions a text mixture containing caffeine, paracetamol, morphine, codeine, heroin, and acetylcodeine was resolved within 1.5 min. The method was used to determine the concentration of heroin in heroin seizure samples, and the results were in good agreement with those obtained by a validated gas chromatographic method. 相似文献

This commentary aims to take stock of the 2016 presidential elections in the Philippines that led to the landslide victory of the controversial Rodrigo Duterte. It argues that part of Duterte’s electoral success is hinged on his effective deployment of the populist style. Although populism is not new to the Philippines, Duterte exhibits features of contemporary populism that are befitting of an age of communicative abundance. This commentary contrasts Duterte’s political style with other presidential contenders, characterises his relationship with the electorate and concludes by mapping populism’s democratic and anti-democratic tendencies, which may define the quality of democratic practice in the Philippines in the next six years. 相似文献

A review of the literature finds that the development of infants exposed to intimate partner violence (IPV) may vary across sex as boys display more externalizing behavior, while girls show more internalizing behavior. Given this trend, gender- and sex-based analysis (GSBA) may play a critical role in understanding and improving the adjustment of these infants. Researchers are often encouraged to include gender and sex into their analysis, though they are rarely afforded appropriate direction in this process. The intention of this article is to provide guidance in GSBA for research on infant development in families affected by IPV. We present a discussion on GSBA, a review of the literature, explanations for differences in male and female infant development, a set of research priorities, and directions for future work. Findings suggest that a better understanding of the complexities in the adjustment of violence-exposed infants through GSBA may promote childhood development. 相似文献

Fear has long been studied as a consequence of crime given the consistent and ubiquitous nature of fear as a reaction and
the systematic variations in its consequences. Past research has shown significant variations in fear of crime at both the
individual and ecological level. Here we implement a multi-level approach to understanding potential interactions between
perceived safety in one’s neighborhood in relation to social disorganization indicators at the neighborhood level and crime
rates at the county level. The nationally representative sample data (n = 2,610) used in this analysis combines individual level data collected in 2006 from the Panel Study of Religion and Ethnicity
(PS-ARE) with ecological level data at the tract and county level from the 2000 US Census. The findings suggest a three level
interaction negating the well known protection hypothesis of marriage and crime; this essentially means that as being married
or cohabitating decreases the negative effects of being in a community with a high level of familial disruption (percent of
divorced) increases, but that effect is substantively negatively tempered as the violent crime rate of the county rises. 相似文献

The late twentieth century saw a rise of global discourse about heritage. Research on heritage politics, however, has shed little light on heritage practices in schools, especially regarding language, that is, how heritage language is constructed and how it is “inherited” by students of various backgrounds. Heritage language education is often viewed as a means to empower heritage language speakers or to address the diverse needs of students in language classes. In existing works, the individual’s link to “heritage” is assumed as given and stable. More recent works show that the processes and effects of heritage language education are complex and nuanced due to diverse personal backgrounds and changing political economy and cultural politics. The role of schooling in the process of “inheriting” language, however, has not attracted much attention: how students are grouped or tracked into a particular class, for example. After ethnographically investigating various views and practices at a weekend Japanese language school in the northeastern United States throughout 2007 and 2008, the authors of this article argue that heritage language school is not merely a place to reproduce “heritage” by passing it on to students, but it is also a productive site where ways to imagine “heritage” and “inherit” it proliferate. The article analyzes the processes by which what would be considered as merely “speaking Japanese” and “being Japanese” outside heritage language school are differentiated into diverse ways of being Japanese. It suggests a need to investigate school as a site of heritage politics as well as a need for researchers and practitioners to view heritage language education not only as a way to teach language but also as a means to gain an understanding of heritage politics. 相似文献

It is widely acknowledged that political parties in European democracies have become increasingly dependent on state resources, most notably direct state funding. Yet cross-national studies on parties' usage of state resources that are not earmarked for partisan purposes, which require the assessment of informal, intra-organisational practices, are still rare. This article looks at one such practice across 33 parties in five European democracies: namely the ‘taxing’ of national MPs' salaries. Under this practice, candidates who enter elected office on a party ticket are obliged regularly to donate a fixed share of their public salaries to party coffers. The empirical analysis shows that the presence of a taxing rule is more likely in parties with a strong extra-parliamentary organisation, while a leftist ideology facilitates the collection of high salary shares from parliamentarians. Moreover, where party entanglement with the state is particularly pronounced, the partisan usage of parliamentary salaries is easier irrespective of their organisational dispositions. Finally, while in unitary systems national headquarters are usually able to monopolise control over national MPs' contributions, in federal systems regional party executives are able to insist on their share of these payments. 相似文献

Which parties represented in the European Parliament (EP) are able to extract regular donations from their MEPs' salaries and, if they extract donations, how great are they? In the literature on party finances, there has been a lack of attention paid to the use of salaries of elected representatives as a source of funding. This is surprising given that the national headquarters of many parties in Europe regularly collect ‘party taxes’: a fixed (and often significant) share of their elected representatives' salaries. In filling this gap, this article theoretically specifies two sets of party characteristics that account for the presence of a taxing rule and the level of the tax, respectively. The presence of a tax depends on the basic ‘acceptability’ of such an internal obligation that rests on a mutually beneficial financial exchange between parties' campaign finance contributions to their MEPs and MEPs' salary donations to their parties. The level of the tax, in contrast, depends on the level of intra‐organisational compliance costs and parties' capacity to cope with these costs. Three factors are relevant to this second stage: MEPs' ideological position, the size of the parliamentary group and party control over candidate nomination. The framework is tested through a selection model applied to a unique dataset covering the taxing practices in parties across the European Union Member States. 相似文献

This is the first study of unwanted sexual experiences in the collegiate "hooking-up" culture. In a representative sample of 178 students at a small liberal arts university. Twenty-three percent of women and 7% of men surveyed reported one or more experiences of unwanted sexual intercourse. Seventy-eight percent of unwanted vaginal, anal, and oral incidents took place while--"hooking up,"--whereas 78% of unwanted fondling incidents occurred at parties or bars. The most frequently endorsed reason for unwanted sexual intercourse was impaired judgment due to alcohol. The most frequently endorsed reason for unwanted fondling was that it happened before the perpetrator could be stopped. Of those affected by unwanted sexual intercourse or unwanted fondling, 46.7% and 19.2% reported unwanted memories, 50% and 32.7% reported avoidance and numbing responses, and 30% and 26.9% reported hyperarousal responses, respectively. A preliminary model of unwanted sex and collegiate social dynamics is proposed to provide a heuristic for further research. 相似文献
