ABSTRACT

Beginning with Karl Marx, theorists have seen individual autonomy and ideology as opposing elements. Ideology was considered the product of mental, cultural or social constraints. People did not choose their world view – they fell victim to it. With the increase of individual autonomy, however, ideology would wither away. In the late 20th century, the advocates of individualization theory have similarly predicted the vanishing of clear-cut ideological divisions in a world in which any form of collective identity was difficult to sustain. Political eclecticism and the mixing of different political world views would become the new norm. Politics was now ‘beyond left and right’, as Anthony Giddens once famously argued. In my article, I show that this understanding of the relationship between individualization and ideological polarization is flawed. By discussing the extreme ideological polarization in the U.S., I disprove the notion that our need for ideology vanishes the more our freedoms expand. On the contrary, precisely the increase in individual autonomy – in terms of mobility patterns, media use and lifestyle differentiation – has helped to turn the country into a series of closed echo chambers and to deepen the ideological fault lines of American society.  相似文献

ABSTRACT

In order to better understand the dynamics of international cooperation on democracy promotion with authoritarian regimes, this article looks into the processes and results of negotiations on democracy (promotion) between the European Union (EU) and two of its North African neighbours (Morocco, Tunisia) in the decade leading up to the Arab uprisings. Asking if, how, and to what effect the EU and its Mediterranean partners have negotiated issues related to democracy promotion, it analyses official documents issued on the occasion of their respective association council meetings in 2000-2010. It shows that partners have indeed addressed these issues since the early 2000s, however, without engaging in substantive exchanges. Most of the time, conflicts have been neither directly addressed nor resolved. Where there are traces of actual negotiations leading to an agreement, these are clearly based on a logic of bargaining rather than arguing. These findings challenge the picture of harmony and cooperation between the EU and Morocco. Furthermore, they point to the low quality of these exchanges which reinforces the dilemma of international democracy promotion in cooperation with authoritarian regimes.  相似文献

X-ray photoelectron spectroscopy (XPS) is a widely used technique to characterize the surface chemistry of materials. It plays a crucial role in accessing qualitative and quantitative information and in detecting the presence of chemical functional groups on the surface of any material. The forensic methods available to detect and identify elements and organic/inorganic compounds are often destructive, so evidence cannot be re-analyzed. However, XPS allows rapid analysis of samples without damaging them. Recently, an increasing number of forensic researchers have begun to study certain chemical information on fingermarks. In this study, the authors aimed to present the applicability and power of XPS imaging in fingermark analysis which can also provide specific information about the fingermark chemical composition. Herein, monochromated X-ray (Al Kα) spot size was fixed at 50 μm. XPS mapping resulted in the acquisition of spectra at each pixel, in an array of 41 × 30 pixels with a step size of 50 μm. Then, a simple discussion has been made about how the scanned surface spectrum and basic snapshot spectra are used to identify different components at a fingertip of a scanned surface area (~3 mm2). Hence, a fingermark pattern contaminated with caffeine, TiO2, and Pb/PbO deposited on the silicon wafer can be chemically mapped and visualized by XPS using principal component analysis (PCA). Thus, the present study showed the possible applicability of XPS for the identification of illicit drugs of abuse, gunshot residue, and skin care products on latent fingermark by mimicking a crime scene evidence.  相似文献

This article is on one of the longest-lived medical institutions of the Ottoman Empire, the Haseki Hospital. I will try to glimpse to the daily workings of the Haseki Hospital and the transformations it underwent in terms of the services it offered, its patients, its social functions, and its relevance for the urban lives of the destitute women of the empire for the period between the 1830s and 1893. During that period, the Haseki Women's Hospital was an institution hosting poor and destitute women as well as pregnant, ill, feeble-minded, convicted women, widows, prostitutes, and orphans. Although it has been called a hospital, it has been used as a women's hospital, lying-in clinic, madness asylum, widow's house, orphanage, and a women's prison. I submit that the Haseki Women's Hospital fulfilled a dual purpose by combining social relief services with medical care for female patients. Besides being a locus of medicine, the hospital was also a site where women in the margins were confined and isolated, but also received care otherwise denied to them. Along these lines, this article searches the vulnerability of the destitute women of nineteenth century Istanbul.  相似文献
