When multiple taxing jurisdictions overlap and fail to account for one another’s actions, they over-tax the common base. This is a prediction of the anticommons model, in which numerous parties have authority to exclude others from using a resource. This model further predicts that when governments over-tax the base, private parties will underutilize the resource, and underutilization will be greater as the number of parties with exclusion rights rises. We test these predictions by studying cell phone taxation and local option tax authority, which allows some cities, counties, and special-purpose districts to levy taxes on cell phone use. Consistent with theory, we find that the tax rate on cell phone service is higher when local governments have the option to tax. Further, the percentage of households owning cell phones is lower when there is the local option to tax, and ownership rates fall with the number of taxes levied.  相似文献

On June 20, 2009 one image became a symbol of violence, as well as a rallying cry for a movement that contested the disputed election of hardline Iranian President Mahmoud Ahmadinejad. The image captured the murder of a 26 year old protester named Neda Agha-Soltan, and showed a first-hand account, in bloody detail, of the savagery of state killing. With the help of social media, the video received mass attention from news organizations in the United States by June 22, 2009. Cursory analysis of the New York Times and The Washington Post, representation of Neda’s death, reveals an Iranian government that was unafraid to violently repress a democratic movement. It is my contention here that such a construction was framed by an Orientalist discourse which helped to fabricate three distinct deaths of this murdered protester. First the lasting images of death became a symbol of freedom; Neda’s second death showed a grievable life, one that provided an emotional space for a US audience; and finally her third death which became a means of defining and (re)stabilizing Orientalized perceptions of Iran as violent and barbaric. Ultimately, these three deaths became an instrument that would help justify the call for US intervention on behalf of Western morality and humanitarian aid.  相似文献

Disasters such as flash flooding, mass shootings, and train and airplane accidents involving large numbers of victims produce significant opportunity for research in the biosciences. This opportunity exists in the extreme tails of life events, however, during which decisions about life and death, valuing and foregoing, speed and patience, trust and distrust, are tested simultaneously and abundantly. The press and urgency of these scenarios may also challenge the ability of researchers to comprehensively deliver information about the purposes of a study, risks, benefits, and alternatives. Under these circumstances, we argue that acquiring consent for the immediate use of data that are not time sensitive represents a gap in the protection of human study participants. In response, we offer a two-tiered model of consent that allows for data collected in real-time to be held in escrow until the acute post-disaster window has closed. Such a model not only respects the fundamental tenet of consent in research, but also enables such research to take place in an ethically defensible manner.  相似文献

The fact that university degrees are accepted throughout Europe has led to the founding of medical faculties, especially in Central and Eastern Europe, that offer medical studies in German or English and thus attracting students from richer Western European countries like Germany. Unlike medical studies in Germany, access to these foreign universities is not dependent on the final school exam grade, but on the ability to pay high tuition fees. The article compares the social class background of medicine students in Germany with German medicine students in Hungary. The analysis shows that the percentage of medicine students who come from higher social classes is even higher in Hungary than it already is in Germany. Studying medicine in Hungary primarily serves as an immediate reproduction of the parents’ profession as many of German medicine students in Hungary have a parent who belongs to the medical profession. The case of German students studying medicine abroad illustrates how Europeanization and Globalization have changed the reproduction of social inequalities; upper classes profit most from the new opportunities.  相似文献

The article has two objectives: First, pursuant to the recent papers on a “sociology of (e)valuation,” an extension of Bourdieusian field theory will be presented, which reacts to three problems with this theory that were expressed in the critical reception: the immanent tendency to emphasize reproduction more strongly than transformation; the disregarding of technology; and the simple dualism of cultural and economic logic. To begin with, a dynamization of the research program will be undertaken, in that fault lines and transformation dynamics will be revealed that could lead to the invalidation of Pierre Bourdieu’s strict homological assumptions. Following up on that, it will be shown how technology, which was neglected by Bourdieu, can become an (external) factor that causes fundamental changes in fields. Finally, in connection with Jörn Lamla’s reflections on “cultural capitalism” and through a differentiation of the concept of the instance of consecration, a level of analysis will be specified on which the transformation dynamics under discussion can be observed. Secondly, the successful integration of technology in new forms of consecration in the field of pop music will be examined. On the basis of the reaction of classical pop-music journalism to the new value assignment instances that have arisen through digitalization, it can be shown that the challenge arising from new forms of consecration results in negotiatory processes in the field of pop music journalism in which various repositionings in the relationship of cultural and economic logics appear.  相似文献
