This article seeks to generate a more precise understanding of the emergence and perpetuation of warlords. First, it offers a simple, intuitive, and empirically grounded conceptual definition of warlordism. Second, it argues that the primary factor contributing to the success of warlords is the ability to take advantage of price differentials for political, economic, and cultural goods across terrains—in a word, to arbitrage. Third, it illustrates this model with a case study of Khun Sa (1934–2007), the self-proclaimed Shan freedom-fighter and “king” of Burma’s heroin trade. Finally, it suggests that the international community rethink its commitment to the norm of sovereignty in order to combat the proliferation of such non-state violence-wielders.  相似文献

ABSTRACT

Objective: To determine the prevalence of risk behaviors related to cigarette use, alcohol use, nutrition, physical fitness, and sexual behavior. Participants: Participants were 1,075 students attending an urban community college during the Spring 2012 semester. Methods: Data were collected in randomly selected classes using the American College Health Association National College Health Assessment II (ACHA-NCHA II) paper survey and analyzed using Statistical Package for the Social Sciences (SPSS) version 22 for frequencies and chi-square test of independence. Results: The sample population reported poor diet, low rates of physical activity, high rates of overweight/obesity, low rates of condom use for vaginal sex, multiple sexual partners, and unintentional pregnancy. Protective health behaviors included low rates of cigarette smoking and alcohol use, high rates of condoms use for anal sex, and high rates of human immunodeficiency virus (HIV) testing. Conclusion: Students are at high risk for health problems related to poor diet, lack of exercise, and risky sexual behaviors. Additional research is recommended to determine the most effective intervention strategies.  相似文献

Gothic fascism     
This article explores the place of fear in fascism ‐ the fear experienced by fascism, as found throughout Hitler’s writings and speeches, and the fear fascism fabricates in order to sustain itself. The article suggests that this fear overlaps and intersects with a shift in the culture of the Gothic in the late‐nineteenth century, such that fascism’s enemy comes to be interpellated as a truly monstrous figure. An exploration of the shifting place of the vampire in late‐nineteenth century Gothic culture creates the possibility of exploring the Gothic opening through which fascism came to both articulate its own fear and to generate a more widespread political fear and social insecurity.  相似文献

Objective: To evaluate the representation of minority groups in randomized control trials (RCTs), and the frequency with which this information is reported.

Study Design: Reviewers collected data on the racial/ethnic composition of study samples from all RCTs published in six leading medical journals in 1999.

Results: Of the 280 RCTs, most (204, 71.3%) provided no information on the race/ethnicity of participants. Of the 89 U.S.-based RCTs, 50 (56.1%) reported their minority distribution. Relative to other trials, those funded by the National Institute of Health (NIH) (n = 52) were more likely to report race/ethnicity data (55.8% vs. 23.7%; χ2 = 20.9, p ≤ 0.001) and to include nonwhite participants (13.5% vs. 12.5%; χ2 = 22.7, p ≤ 0.001).

Conclusion: Minority groups are currently under-represented in clinical trials. Information on the race and ethnicity of clinical trial participants is currently underreported in six leading medical journals. Reporting of minority group information was significantly better only in NIH funded trials, which also were more likely to include nonwhite participants. This suggests that mandatory reporting policies may have a positive effect on both reporting and representation.  相似文献
