Helicobacter pylori are ubiquitous Gram-negative bacteria with a high estimated level of infection in the world populations, but a majority of the infected persons are asymptomatic. This pathogen has been classified by the World Health Organization as a class I carcinogen and recognized as the causal agent of most peptic ulcers and chronic gastritis that might lead to stomach cancer. Although not all the transmission pathways of these bacteria into humans have been properly identified, enough data have sugg... 相似文献

ABSTRACTIn the years since the fall of the civil–military dictatorships in the Southern Cone, considerable attention has been paid to first-person testimonies of human rights victims. A great number of these have been by women who narrated sexual political violence. However, while there has been work done on the relation between terror, trauma, and spectacle in postdictatorial television shows, rarely has this also included a gendered perspective. In this article we seek to open this area of discussion by evaluating the manner in which women’s televised testimonies of political sexual violence have been constructed on late night talk shows in Chile, using recent history and memory theory, as well as feminist theory on the representation of sexual violence in mass media. 相似文献

Performing arts organizations are characterized by different objectives other than revenue. Even if, on the one hand, theaters aim to increase revenue from box office as a consequence of the systematic reduction in public funds; on the other hand, they pursue the objective to increase its attendance. A common practice by theaters is to provide incentives to customers to discriminate among themselves according to their reservation price, offering a schedule of different prices corresponding to different seats in the venue. In this context, price and allocation of the theater seating area is decision variables that allow theater managers to manage their two conflicting goals to be pursued. In this paper, we introduce a multi-objective optimization model that jointly considers pricing and seat allocation. The framework proposed integrates a choice model estimated by multinomial logit model and the demand forecast, taking into account the impact of heterogeneity among customer categories in both choice and demand. The proposed model is validated with booking data referring to the Royal Danish theater during the period 2010–2015. 相似文献
