After September 11, 2001, a great deal of public and policy attention has been devoted to border security, passports, and the global mobility regime. This article examines the context of the global regulation of movement of individuals and the evolution of the passport in particular. It then examines the current American border security architecture. The creation of the Homeland Security Department reflects a sea-change in the view of the border, and these new policies are evaluated in regard to three cases: the U.S./Canada border, the document/examination policies at the American borders, and the European Schengen mobility regime.  相似文献

While the global justice movement has often been said to suffer from notable North-South divisions, survey findings from the World Social Forums 2005 (Porto Alegre, Brazil) and 2007 (Nairobi, Kenya) contradict this notion. Logistic regression analyses show no systematic variation between the political attitudes held by respondents from the global North and those held by respondents from the South. While Southern activists are somewhat more likely to hold radically anti-capitalist views than their Northern colleagues, North-South differences regarding the question of whether capitalism should be abolished or reformed are neither robust, nor statistically significant. Response patterns differ, however, between participants from the world-system’s periphery and semiperiphery, as well as between the majority of Latin American participants in the Porto Alegre survey and the majority of African participants in the Nairobi survey. In short, South-South differences among respondents from different world-systemic zones (periphery versus semiperiphery) and socio-geographic regions (Latin America versus Africa) appear to be more pronounced than the oft-assumed North-South differences. The common North-South dichotomy, while quite popular among authors criticizing the notion of an emerging global civil society as empirically inadequate, turns out to miss the mark.  相似文献

The United States accuses China of subsidizing its entire export economy through artificially undervaluing its currency. China accuses the United States of fiscal profligacy while flooding the world with easy credit to keep its economy afloat. This dispute reflects the reality that the world's two largest economies are built on opposite dynamics of production and savings vs. consumerism and debt. In Europe, the wages of unsustainable debt that financed the welfare state have also come due. Rebalancing the global economy in this context is not only a matter of fixing exchange or interest rates and extending the retirement age. It must also involve a recalibration of democracy in both East and West. Two Nobel economists, the Greek prime minister, a ranking Chinese economist and the former chief economist of the IMF address these issues.  相似文献

Childhood sexual abuse has been associated with HIV transmission risk behavior in men who have sex with men. This study examined an adapted model that was originally developed to explain the relationship between childhood sexual abuse and HIV risk behavior among women in a sample of men who have sex with men. Men attending a large gay pride event (n=647) completed anonymous surveys that assessed demographic characteristics, childhood sexual abuse, symptoms of dissociation, trauma-related anxiety, borderline personality characteristics, hopelessness, substance use, and sexual risk behavior. A latent variable partial least squares analysis was conducted to test the interrelationships between childhood sexual abuse, exchanging sex for money or drugs, emotional disturbances, drug use, substance use in the context of sexual behavior, and sexual risk behavior. The model fit the data well and accounted for 10% of the total variance in sexual risk behavior. History of childhood sexual abuse predicted exchanging sex for money or drugs and this relationship was partly accounted for by active drug use. Substance use proximal to sexual behavior also emerged as a key factor in predicting sexual risk behavior. Findings from this study, therefore, indicate a direct association between history of child sexual abuse and high risk for HIV infection related to engaging in sex trade.  相似文献

The authors previously explored invention licensing from the university's perspective. In this paper we focus on the process from the perspective of firms activity engaged in licensing technology. A survey of industry licensing professionals addresses why some firms license technologies from universities and why others do not. The paper then considers the stage of development of university technologies, the characteristics of their licensing contracts, and sources of information about university technologies, all to better understand how the process works and what advantages and disadvantages it offers to all participants.  相似文献

Over the past decade, the use of force by the police has become an important public policy concern and topic of social science research. A number of researchers hypothesized about the factors that explain the amount of force used by police officers. Prior research focused almost exclusively on the highest level of force used in police-citizen interactions and neglected to examine the relative amount of forced used by the police compared to that used by suspects. To address this shortcoming, this study analyzed data from three years of official use-of-force reports in the Miami-Dade Police Department (MDPD). Contrary to studies that examine only the use of force by the police, this study found that the relative amount of force used by the police was greatest in the less threatening types of offenses. The implications of this study for research and policy are discussed.  相似文献
