A tragedy of the anticommons: local option taxation and cell phone tax bills

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.     

Seeing Like an Orientalist State: The Three Deaths of Neda Agha-Soltan

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.     

Ökonomisches Kapital der Eltern und Medizinstudium im Ausland. Wie Europäisierungs- und Globalisierungsprozesse die Reproduktion sozialer Ungleichheiten verändern

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.     

Konsekrationsinstanzen im digitalen Wandel – Beiträge zur Erweiterung des feldanalytischen Forschungsprogramms am Beispiel populärer Musik

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.     

大鼠过敏性休克死后血清IgE、类胰蛋白酶的变化

目的观察大鼠过敏性休克死亡后血清IgE、类胰蛋白酶的变化规律,探讨其与死亡时间(PMI)、尸体及样本保存环境的相关性。方法建立大鼠过敏性休克死亡动物模型并分组,包括室温组、冷藏组、冷冻组、人工溶血组、血清样本保存组,并设立对照组。大鼠处死采血后,按离心后上层血清颜色进行溶血程度分级。通过ELISA法检测血清IgE、类胰蛋白酶在各组中的质量浓度。结果大鼠过敏性休克死亡后血清IgE、类胰蛋白酶水平明显高于对照组;室温、冷冻保存下血清IgE、类胰蛋白酶随PMI的不同有明显变化,冷藏保存下浓度相对稳定;随溶血程度的增加,血清IgE、类胰蛋白酶水平均呈升高趋势。样本不同温度条件下保存25 d,血清IgE、类胰蛋白酶无明显变化。结论大鼠过敏性休克死后血清IgE、类胰蛋白酶明显升高,但其水平受PMI、环境温度影响较大,尤其是室温或冷冻保存。
