The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization. 相似文献

Allele frequencies, together with some parameters of forensic interest were estimated for nine STRs included in the AmpF/STR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA) in a sample of 215 unrelated individuals from Cartagena (Colombia). For all loci, no significant deviations from Hardy-Weinberg equilibrium were observed. Comparative analysis results between our data and those from other Colombian and African population samples revealed significant differences, except with two Colombian Caribbean Coast sub-regions. 相似文献

Economical liberalization, market globalization and soy expansion stimulated the advance of big transnational companies in the Southern Cone countries (Brazil, Argentina, Paraguay and Uruguay). Currently, the main corporations acting on the last links of the productive chain are ADM (Archer Daniels Midland), Bunge, Cargill and Dreyfus (the ABCD firms), global leaders in the soy trade. The objective of this contribution is to analyze the different strategies these companies articulate in the Southern Cone, and their dynamics in local space through market relations with local producers. The results show the rapid and intense process of denationalization of the firms in the soy productive chain as well as the high level of market internationalization and company concentration. In spite of this, this study shows that all transnational power of ABCD firms, which seems so abstract and intimidating when seen in the global scale, depends on its basis of the formation, maintenance and exploration of relations of proximity, trust and reciprocity with local actors (especially rural producers), including family friendship linkages. 相似文献

Information campaigns are key elements of elections. Past research has established the importance of campaigns in informing and educating citizens, and ultimately strengthening participatory democracy. While the Internet has increased the possibilities to disseminate information campaigns and eased access to political information, it is still debated whether online campaigns are effective in stimulating political interest and participation among the general public. The issue is not only one of access, but also of use of information. The investigation of main effects of campaigns obscures the fact that citizens may not use information in the same way and reap the same political benefits. In this study, I examine the conditional effects of a new type of Web information campaign, Voting Advice Applications (VAAs), on the political engagement and electoral participation of citizens with varying levels of education. By investigating who benefits most from using these apps, I evaluate whether VAAs reinforce patterns of participation or mobilize new people in politics. Building on political behavior research, communication theory, and social psychology, I study the differential effects of VAAs with an innovative randomized field experiment design. The results confirm that VAAs can stimulate the political engagement of the public. However, there is no significant impact on electoral participation. In addition, the evidence shows that VAAs work differently for more or less educated citizens, and that the lower educated users benefit the most from VAAs as they become more interested in the election and more motivated to vote. 相似文献

The contemporary interaction of the body with information, computing, and communication technologies in Western societies has contributed to a change in our understanding of the concept of the human being, while implying that old ideas surrounding corporeality need to be rethought. It is contended here that the virtual reality film, with its focus on cyberspace, offers opportunities for understanding the complex relationship between gender and information technologies and creates spaces in which the gendered body can be reconsidered. Films like The 13th Floor, The Matrix, and Johnny Mnemonic display digital media and virtual subjects that mirror our complex relationship with technology. The present paper proposes three different ways of representing the interaction between humans and technology: “the penetrated body”, “the cyber-body”, and “the simulated body”. This distinction responds to a hierarchy in which some categorizations are more transcendent than others, and confer different degrees of flexibility regarding the redefinition of the gendered body in the texts involved. 相似文献

Selectively using Tocqueville, many social scientists suggest that civic participation increases democracy. We go beyond this neo-Tocquevillian model in three ways. First, to capture broader political and economic transformations, we consider different types of participation; results change if we analyze separate participation arenas. Some are declining, but a dramatic finding is the rise of arts and culture. Second, to assess impacts of participation, we study more dimensions of democratic politics, including distinct norms of citizenship and their associated political repertoires. Third, by analyzing global International Social Survey Programme and World Values Survey data, we identify dramatic subcultural differences: the Tocquevillian model is positive, negative, or zero in different subcultures and contexts that we explicate. 相似文献
