    The evaluation of control measures against Schistosoma mekongi in Cambodia by a mathematical model

    We constructed a mathematical model for the transmission of Schistosoma mekongi in Cambodia. The simulation of the model will be instrumental in planning schistosomiasis control measures. The model includes two definitive hosts, humans and dogs, as animal reservoirs. Dogs are recognized to play an important role in schistosomiasis transmission in Cambodia. For the purpose of dealing with age-specific prevalence and intensity of infection, the human population was classified into eight age categories in the model. To describe the seasonal fluctuation of the intermediate host population of S. mekongi, the "Post-Spate Survival" hypothesis was adopted for the population dynamics of Neotricula aperta present in the Mekong River. We carried out simulations to evaluate the effect of universal treatment (UT) and targeted mass treatment (TT) with praziquantel on the reduction in prevalence of S. mekongi. The simulations indicated that biyearly UT for 8 years or yearly TT for 5 years after three courses of yearly UT could reduce the prevalence to below 5% when a UT or TT coverage of 85% of inhabitants was achieved. The simulation suggested that the suppression of S. mekongi in Cambodia would be possible by UT or TT with a high coverage rate.</p

    Normative Recursion : on Recursive Grounding and the Capacity for Radical Critique in Formal Pragmatics, Recognition, Social Freedom and Justification

    This thesis explores the meta-ethical question: What properties would be required of a normative critical concept in order for it to be (a) derived from the social facticity of prevailing norms, practices and institutions in a given society and (b) still be capable of informing radical critique? This thesis takes radical critique to mean one that escapes all charges of status quo biases and thus truly transcends the immanent content of the norms, practices and institutions from which it was derived.This thesis asserts that the necessary property of such a concept is recursion. That is, the property of a self-referentiality that allows for something to hierarchically contain copies of itself. The idea of finding the property of recursion in normative political theory and defending its utility is undertheorized in the political theory literature. By locating the property of recursion in the formal pragmatics of Jürgen Habermas, in Axel Honneth’s concepts of recognition and social freedom and in Rainer Forst’s concept of justification, this thesis remedies this situation. In doing so, a space is carved out for normative political theory between foundationalism and anti-foundationalism and between the utopian and realist approach

    Doing Media History in a Digital Age:Change and Continuity in Historiographical Practices

    This article explores the challenges which digital media brings into the field of media history. It starts out by examining prominent television historians’ understanding of digital archives as revolutionizing media historiography. These claims are examined by holding them up against texts that discuss wider issues in historiographical practices related to television history and transnational comparisons. This investigation is paired with my own experiences and the many methodological challenges I have encountered using digitalized sources for my new research. I end up concluding that digital archives in themselves make little difference to scholarly media history. In light of the lacking impact, I argue that we should study the cultural economy of these archives to better understand the corporate, political, and economical structures that govern their content and which also set the course for online digital processes that are active history-producing entities themselves. </jats:p
