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 work...examines the cultural dimension of sexuality and fertility of women from [low-income] sectors in Peru. It intends to explain the cultural processes that fall into the intermediate variables of fertility, such as marriage rate, contraception, breastfeeding and...abortion. These dimensions of sexual and reproductive life are analyzed according to two explanatory dimensions: generation and cultural context of socialization. The general hypothesis is that a cultural process of homogenization of the values and behaviors has been taking place over sexuality, in such a way that the younger generations will show similar standard behaviors and values no matter their context of socialization; in the meantime, in the older groups there will exist contextual differences in these dimensions."

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

AbstractGlobal, national and local policies and programmes for agricultural development are recurrently justified based on their alleged role in improving food and nutrition security. However, strikingly little evidence is available to prove that a direct, household-level link between agricultural production and improved nutrition exists. The objective of this special issue is to systematically and empirically test, using data from Africa and South Asia, whether a relationship between household agricultural production and nutrition can be found. Overall, the studies in this special issue support the hypothesis that household agricultural production has direct and important linkages with dietary patterns and nutrition. 相似文献

An unprecedented number of Western women have recently joined the Islamic State of Iraq and Syria (ISIS). The group has envisaged strictly non-combat roles for them, but violence is an essential part of their embraced ideology and several signs suggest that they could claim a more militant role. Their marginalization, however, is essential for the preservation of ISIS's power system and it is consequently unlikely that it would accommodate such aspiration, at least in the areas of the proclaimed caliphate. It could be different in the West, where women returning from conflict areas or those, even more numerous, anxious to join but unable to travel, could engage in violent acts. 相似文献

This paper studies changes in voting preferences over election campaigns. Building on the literature on spatial models and valence issues, we study whether (1) ideological distance to political parties, (2) assessments of party competence to handle different policy issues, and (3) voter-updated candidate evaluations are factors that explain shifts in voter choices in the weeks preceding the election. To test our hypotheses, we use data from three survey panels conducted for the 2008, 2011 and 2015 Spanish general elections. Our findings show that valence factors are more influential than ideological indifference to account for campaign conversion. 相似文献

AbstractBeyond all the material and economic losses that natural disasters produce, post-disaster environments can alter the social capital of a community by affecting social norms, attitudes, and people’s behaviour. To analyse this issue, we empirically investigate the effect that the aftermath of a disaster can have on trust and reciprocity of people within communities. We do this by comparing outcomes of trust games conducted in earthquake-affected and non-affected rural villages one year after the 2010 Chilean earthquake. Our findings show that while trust levels do not differ across cases, reciprocity is lower in earthquake-affected areas. 相似文献
