Although security has become a common framework for analyzing dispositifs that aim to control irregular migration, island spaces themselves are seldom considered as security dispositifs. The case of Malta, where detention is mandatory upon arrival, epitomizes what could be conceptualized as a “sentinel island” within the European Union. This article demonstrates how the interaction between political discourse, administrative practices, and migrants’ experiences contributes to turning the island into a form of total-institution setting. The empirical data is based on qualitative fieldwork that combines ethnographic observation, migrants’ individual narratives and semi-structured interviews conducted with European and national policy makers.  相似文献

The contemporary interaction of the body with information, computing, and communication technologies in Western societies has contributed to a change in our understanding of the concept of the human being, while implying that old ideas surrounding corporeality need to be rethought. It is contended here that the virtual reality film, with its focus on cyberspace, offers opportunities for understanding the complex relationship between gender and information technologies and creates spaces in which the gendered body can be reconsidered. Films like The 13th Floor, The Matrix, and Johnny Mnemonic display digital media and virtual subjects that mirror our complex relationship with technology. The present paper proposes three different ways of representing the interaction between humans and technology: “the penetrated body”, “the cyber-body”, and “the simulated body”. This distinction responds to a hierarchy in which some categorizations are more transcendent than others, and confer different degrees of flexibility regarding the redefinition of the gendered body in the texts involved.  相似文献

美国"重返亚洲"是美国"焦虑时代"的"应急反应",随着美国对亚太事务的深度介入,这种"应急反应"已转变成为美国完整的"亚太战略"。从地缘政治考量,美国的亚太战略是以巩固亚太传统的盟友关系为基础,以化解中印崛起带来不确定变量为重点,以插手热点敏感问题为手段,推行全球霸权主义战略的体现。"围堵中国"只是美国亚太战略的一部分。中国可利用美国亚太战略的空间错位,强化共同利益纽带,巩固周边安全格局,为推进小康社会建设和祖国统一大业,创造有利的外部条件。  相似文献

Abstract

The current study surveyed a random sample of Texas law enforcement officers (n?=?109) about their knowledge regarding behaviors indicative of deception. The officers were not highly knowledgeable about this topic, overall performing at a chance level in assessing how various behavioral cues relate to deception. Confidence in one's skill was unrelated to accuracy, and officers who reported receiving the most training and utilizing these skills more often were more confident but no more accurate in their knowledge of the behaviors that typically betray deception. The authors compare these results to previous studies that have examined officers’ beliefs in other countries and discuss the implication of these results in terms of developing future training programs that may debunk the common misconceptions that officers possess.  相似文献

Behaviors developed in adolescence influence health later in life. The purpose of this study was to investigate the frequency of health care provider's discussion of health behaviors with overweight and non-overweight adolescents and identify demographic and health behaviors related to exercise, hours of television viewing, and weight issues associated with these discussions. A Cross sectional survey of urban adolescents was conducted. Trained interviewers administered surveys over a three month period in 2001 at an urban academic pediatric and adolescent clinic. The 252 adolescents surveyed had a mean age of 15 with 49% categorized as being at risk for overweight/overweight and 51% as normal weight using the CDC percentiles for BMI. While 16% of the adolescents reported that their physician or nurse discussed the amount of television they watched, rates of discussion related to exercise (58%), and weight (54%) were much higher. In multivariate analyses, health care provider discussions with adolescents regarding exercise were more common for overweight (O.R.=2.42, 95% C.I. [1.28–4.57]) and at risk for overweight (O.R.=1.98, 95% C.I. [1.03–3.81]) adolescents, whereas physician discussion of television viewing was not associated with weight. Discussions of weight were more common for female (O.R.=2.18, 95% C.I. [1.21–3.95]), African-American (O.R.=2.53, 95% C.I. [1.40–4.57]), and overweight (O.R.=3.92, 95% C.I. [1.97–7.81]) adolescents. Even after adjusting for weight, race and gender strongly influenced the frequency of discussions about weight in physician offices. Although health care providers frequently address weight and exercise with adolescents, more discussions related to sedentary behaviors such as television viewing may be warranted to address adolescent obesity.Received PhD in Epidemiology from University of California, San Diego.

Using an innovative survey of protest participants and nonparticipants from five major street demonstrations in Mexico City in 2011 and 2012, this study tests the assumption that influences on protest participation vary across different types of events; namely, ritual demonstrations and reactive protests. The comparison is based on two assumptions: that these are two of the dominant forms of protest in contemporary Latin America, and that specifying the context for different types of social movement participation provides a better understanding of the individual mobilization process for groups seeking to defend their rights or gain new benefits. The comparative analyses reveal some crucial differences. Political interest and previous political experience are more influential in the decision to take part in reactive demonstrations. For ritual demonstrations, the decision to participate tends to be driven more by personal and organizational connections.  相似文献

2007年6月,美韩双方签署了《美韩自由贸易协定》。美韩之间为什么要签署该协定?该协定对两国国内分别产生了哪些影响?该协定为何至今没能获得美国国会的通过?针对上述问题,本文结合美国贸易政策理论,从体系、国家和社会三个层面对其进行了分析。《美韩自由贸易协定》的签署及其实施,在体系层面上将会为双方带来经济、政治和战略上的多重收益,而在社会层面上却产生了不同的反应。尽管由于国内经济困难和利益集团的掣制使得协定的通过还面临不小的阻力,但基于协定所蕴含的重要价值和两国政府对此认识的高度一致,协定获得通过只是时间上的问题。  相似文献

In this study, the Raman spectra of 21 phenethylamines were obtained using far‐red excitation (785 nm). The distinguishing ability of Raman for phenethylamines, especially for phenethylamine regioisomers and structural analogues, was investigated. Here, the evaluation of a cross section of Raman spectra demonstrated that all types of phenethylamines were distinguishable, even for certain structural analogues with high spectrum similarity. Raman exhibited high distinguishing ability for phenethylamine regioisomers that differ in the substitution position of halogen, methoxy, alkyl, or other substituted groups; as well as for structural analogues containing different groups, such as furanyl, 2,3‐dihydrofuranyl, halogen, and alkyl substituted at the same position. The Raman spectra for homologues with differences in only a methyl group were found to be highly similar; however, their spectra demonstrated small but detectable differences. Four analogue mixtures and 59 seized samples were also analyzed to study the practical use of the Raman method in forensic field. 95% of the seized samples were correctly identified, which significantly validated the ability of Raman method in identifying the correct isomers. Accordingly, this study provides a non‐destructive, high‐throughput and minimal sample preparation technique for the discrimination of phenethylamines.  相似文献

Gene and genotype frequencies in relation to the D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 loci were determined in a sample of 290 unrelated individuals (204 Caucasians and 86 mulattoes) living in the city of S?o Paulo, Brazil. The sex test Amelogenin was also performed in all subjects from our sample, revealing the expected sex in all instances. Allele frequency data obtained from the analysis of these samples were in the usual range of other population groups with similar racial background. In the sample of Caucasian individuals, panmictic proportions were ruled out in relation to TPOX and CSF1PO loci, but only in the latter was the overall frequency of heterozygotes significantly less than expected. In the sample of mulattoes, Hardy-Weinberg proportions were rejected in relation to FGA and CSF1PO loci, but in no instance were the overall numbers of heterozygotes different from the corresponding expected ones under panmixia. Taking into account all this and also the number of tests performed, the degree of genetic heterogeneity of Brazilian populations, and the critical level reached by the significant results (1% < alpha<5%), the departures from panmixia here observed can be considered to be negligible in altering significantly biologic relationship odds calculated under the assumption of random matings.  相似文献
