Over the last thirty years, Mexico has undergone an important consolidation of its institutional framework, focused primarily on the electoral and political system. This process of political change was accompanied by a significant transformation and liberalization of the financial and economic system. Mexico’s current situation proves that both processes do not yield satisfactory results when social problems are left unattended. In fact, the transition from a noncompetitive political system to a more democratic one, has not guaranteed better living conditions for most of the population, in part because there is practically no participation in public life on behalf of most of the citizenry. This article reflects on the fundamental importance of citizens’ participation in democracy. Particular attention is paid to public participative budgets as factors which may contribute to democracy’s consolidation and quality, but which have had negligible impacts thus far as is illustrated by public participative budgets initiatives that have been held in Mexico City.  相似文献

In legal medicine the correct determination of the time of death is of utmost importance. Recent advances in estimating post-mortem interval (PMI) have made use of vitreous humour chemistry in conjunction with Linear Regression, but the results are questionable. In this paper we present PMICALC, an R code-based freeware package which estimates PMI in cadavers of recent death by measuring the concentrations of potassium ([K+]), hypoxanthine ([Hx]) and urea ([U]) in the vitreous humor using two different regression models: Additive Models (AM) and Support Vector Machine (SVM), which offer more flexibility than the previously used Linear Regression. The results from both models are better than those published to date and can give numerical expression of PMI with confidence intervals and graphic support within 20 min. The program also takes into account the cause of death.  相似文献

Recent developments on postmortem interval estimation (PMI) take an advantage of the autolysis process, pointing out to the analysis of the expression of apoptosis and autophagy genes towards this purpose. Oxidative stress plays a role in this signaling as a regulatory mechanism and/or as a consequence of cell death. Additionally, melatonin has been implicated on apoptosis and autophagy signaling, making melatonin a suitable target for PMI determination. The aim of this study was to investigate the early PMI through the analysis of the expression of autophagy genes as well as oxidative stress and melatonin receptor. Our results demonstrated a rapidly increased on the expression of autophagy genes according to the expected sequence of events, then a marked decrease in this expression, matched with the switch to the apoptosis signaling. These results revealed potential candidates to analyze the PMI in the first hours of death, helping to estimate the time-since-death.  相似文献

Biodiversity loss remains one of the most pressing issues for global governance. This situation can be seen in Argentina and Chile through the effects of biodiversity loss caused by the introduction and expansion of beavers in Southern Patagonia. This case is interesting because, despite the Beagle conflict (i.e., the border dispute) between these countries some decades ago, nowadays Argentina and Chile are facing shared environmental problems and both are actively seeking solutions. The main question in this paper is, how did Argentina and Chile search for a solution to shared environmental problems caused by the expansion of beavers in Southern Patagonia? This paper tackles this question and presents the results of the conducted qualitative research. The results indicate that, in order to understand what Argentina and Chile are doing to achieve a solution to their shared environmental problems, research cannot be exclusively focus on domestic affairs. Instead, this issue requires taking into account how international dimensions influenced domestic policies. As this paper argues, in Argentina and Chile, international cooperation is a method of influencing biodiversity governance through funds granted by international organizations and international expert recommendations.  相似文献

Abstract

According to international relations scholars, an important change taking place in the post-Cold War context concerns the lethality of non-state armed groups (NSAGs). Underlying this observation is the conventional assumption that non-state violence is intrinsically illegitimate. This article shifts the analysis of violence away from the terrain of legitimacy, which tends to moralise the difference between state and non-state forces, and towards the terrain of work, where their violence features as part and not separate from a shared political economy. I propose the notion of violence work as a resourceful analytic into the dialectics of everyday violence and the complex processes of value production in social life. Against the background of the extreme cruelty attributed to transnational gangs in Central America, I argue that their violence work is expressive of prevailing modes of accumulating wealth in the region. Drawing on multi-sited fieldwork in Honduras, Guatemala, El Salvador and Mexico, I show how gang violence work animates a system of economic cooperation that engages a wide array of subjects who traverse state/non-state and legal/illegal divides.  相似文献

This paper presents a product development methodology for use with indigenous rural workers. It is based on the revival of cultural and social values, with a focus on the conservation of natural resources. Illustrated by the case of Mixtec craftswomen in Mexico, this paper shows how poor groups can improve their living conditions through innovation and the diversification of their products. The process combines techniques of product development based on marketing, with a participatory focus and continuous improvement, in order to develop a unique and high‐quality product that can be more successfully marketed. The craftswomen are now able to plan their production and can evaluate and commercialise their products.  相似文献

Allele frequencies and some forensic parameters for 12 autosomal microsatellites (CSF1PO, TPOX, THO1, VWA, D16S539, D7S820, D13S317, D5S818, F13A1, FESFPS, F13B, LPL) were estimated from three departments from Northwestern Colombia. The total number of samples analysed was 1045 individuals. Comparative analysis among the three studied departments and with other published Colombian populations were also performed and discussed.  相似文献

The future Law on Biomedical Research, whose draft bill has been approved by the Council of Ministers and that will soon begin its parliamentary process of approval, will regulate, among other matters, the research with embryos. Likewise, it will make a pronouncement on the so-called therapeutic cloning. This report makes a detailed analysis of different matters that must be borne in mind by the legislator in order to face the process of evaluation and approval of said Law in relation with the aforementioned matters. It makes a special analysis of the legal texts of an international nature to which Spain is unavoidably subjected to, in such a way that the legislative text that will finally be approved is not contrary to the dispositions that are within such.  相似文献

The author studies the perception of marriage in the twenty first century, as a fundamental human right, declaring the value and dignity of all human beings, without any discrimination and its self-determination. The author analyzes the legal nature of marriage as an institution and as a contract, addressing an analysis of the reasons and purposes of marriage, and the phenomenon of arranged marriages (matrimonios por complacencia). Thereupon, she studies and reflects on the importance to inform the future spouses that love is the value that sustains the permanence of marriage and the fulfillment of its purposes in the twenty first century.  相似文献
