Contemporary Colombian conjuncture encompasses two dynamics. These incorporate social, economic, political and cultural aspects, whose related rationalities are yet to be mapped out and understood in their complex and multi-layered dimensions and registers. On the one hand, as I will explain throughout the text, we have been witness to on-going peace talks between the government and the Fuerzas Armadas Revolucionarias de Colombia guerrilla group, a whole set of practices of forgiveness, inaugurations of memory museums, the passing of the victims and land restitution law, as well as the recognition of victims and the effervescence of their movements and organizations. These factors have spiralled victims’ demonstrations and fuelled marches all over the country. On the other hand, there are increased rates of foreign investment in those regions that, until as little as a decade ago, were subject to appalling rates of internal displacement, massacres and disappearances, and which now constitute new borders where global capitalism has been able to reconfigure and increase its rates of capital accumulation. In this article, I analyse the processes referred to above and their complex relationships from the vantage point of a cultural studies interrogation of the affective and the popular, focusing on two Colombian regions: Montes de María and Mapiripán. My goal is to understand how different groups and actors are experiencing these processes in their everyday lives. Here, I include victims and their organizations but also government officials and entrepreneurs related to agro-industry initiatives – mentioned below – today refashioned within the new mantra of corporate responsibility. I want to understand the issue of where people are located and what they are doing, facing, consuming, or resisting in terms of these new challenges. Finally, I wish to offer an analytical study that can capture the everyday textures of these processes in a complex and concrete fashion. 相似文献

A smoothed bootstrap method is presented for the purpose of bandwidth selection in nonparametric hazard rate estimation for iid data. In this context, two new bootstrap bandwidth selectors are established based on the exact expression of the bootstrap version of the mean integrated squared error of some approximations of the kernel hazard rate estimator. This is very useful since Monte Carlo approximation is no longer needed for the implementation of the two bootstrap selectors. A simulation study is carried out in order to show the empirical performance of the new bootstrap bandwidths and to compare them with other existing selectors. The methods are illustrated by applying them to a diabetes data set. 相似文献

Over the last decade, we have witnessed the emergence of an academic debate surrounding the relationship between youth and the ‘new media’, with a particular emphasis on the social uses of different digital technologies within the sphere of youth activity. A specific area of research has been dedicated to studying the use of digital media in the context of the so-called youth subcultures. With this article we expect to contribute to this ongoing debate, by examining the problem through an analysis of two interconnected case studies: protest rap and illegal graffiti. Both cases may be defined as subcultures, insofar as they are characterized as alternative, subterranean, and to a certain extent, subversive movements. The empirical ground for this discussion is based on several investigations, with a qualitative basis, carried out by the authors in the course of over a decade in Portugal. This extended time frame allowed ample access to a diversified and matured analytical material and enabled a better perspective of the developments and the mutations involving the appropriation of the digital media. Our researches have shown that digital media and technologies have been gradually integrated in these urban youth subcultures, accomplishing several strategic roles. 相似文献

We propose an influence diagnostic methodology for linear regression models with stochastic restrictions and errors following elliptically contoured distributions. We study how a perturbation may impact on the mixed estimation procedure of parameters in the model. Normal curvatures and slopes for assessing influence under usual schemes are derived, including perturbations of case-weight, response variable, and explanatory variable. Simulations are conducted to evaluate the performance of the proposed methodology. An example with real-world economy data is presented as an illustration. 相似文献
