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

This article analyses how a gendered perspective on community-based tourism (CBT) contributes to the realisation of identity and sovereignty of quilombos. It examines the potential sustainability of CBT coupled with agro-ecological practices within the context of gendered identity politics. Drawing from in-depth ethnographic and archival research conducted between February and July 2015 at Campinho da Independência (Rio de Janeiro, Brazil), the article discusses how female leaders integrate sustainable agro-ecological practices and CBT with environmental education in what they call ‘ethno-ecological tourism’. This approach to CBT strengthens a proudly defiant version of Afro-Brazilian ethnic identity vis-à-vis the state. 相似文献

We all agree on the justification of defending ourselves or others in some situations, but we do not often agree on why. Two
main views compete: subjectivism and objectivism. The discussion has mainly been held in normative terms. But every theory
must pass a previous test: logical consistency. It has recently been held that, at least in the case of defending others from aggression, objective theories lead, in some situations, to normative contradiction. My aim is to challenge the idea
that only objective theories have this uncomfortable feature. In fact, any plausible theory justifying the defense of others, whether
subjectively or objectively, can lead to situations of normative inconsistency. Therefore, the logical test is not the most
fitting one for choosing between different theories of private defense. 相似文献

The new Spanish Law on Artificial Human Reproduction Techniques is analyzed from the scientific, ethical and legal points of view, paying special attention to the preimplantational diagnosis and the experimental utilization of gametes and preembryos. Other items are also analyzed. 相似文献

This paper describes the governance system of Spanish listed firms in the early 1990's. Although the institutional setting of the Spanish Stock Exchanges differs little from other European national markets, we found important differences in several aspects of corporate governance. In particular, some of the standard mechanisms of control (e.g. boards and institutional shareholders) do not play an active role, whereas ownership is relatively concentrated. Moreover, power indices suggest that controlling blocs of large shareholders are very likely to form. We thus conclude that the ownership of shares is a pivotal mechanism in the governance of Spanish corporations. 相似文献

This study explores the experience of ten possible beneficiaries of the measures provided by the Chilean government during the first year of the COVID-19 pandemic through remote semi-structured interviews. The results show a scenario of improvisation. Instead of relying on solid gender equity policies, a patchwork of focused measures was implemented, which increased uncertainty and vulnerability. As a result, women experienced sorrow and despair while facing economic constraints and care tasks mostly on their own. This article shows that care remains invisible in politics while overwhelmingly evident at home. Social care policies are urgently needed. 相似文献

This paper explores the institutionaldeterminants of economic growth in LatinAmerica by taking advantage of recentempirical research that employs subjectiveand objective measures to test for apossible “Northian” explanation that linksinstitutional quality and economic growth.We explore a simple framework that may helpbetter understand the policymakers’ choicesand persistence regarding inward-lookingpolicies that were pursued between the1930s and the 1980s by arguing that in theLatin American case Olson’s (1982) idea ofencompassing interest should be expanded tocover not only the economic stakes of powerholders, but in particular, their psychicincome which includes their politicalstakes, along the lines of recent work byRobinson (1997), Coyne (2002), andothers. 相似文献

非洲面临最重要的挑战就是如何避免并解决冲突,恢复和巩固和平。持久和平是非洲应对其他挑战的先决条件。非洲联盟的建立显示出非洲人民应对挑战的决心,其目标就是要消除贫困,维护和平,使非洲各国走上经济持续发展的道路。中国是最早向莫桑比克提供援助的国家之一,非洲国家视中国为伙伴和盟友,中非合作的前景广阔。 相似文献
