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

This article examines the contested process of law‐making related to the killing of women which resulted in the criminalization of feminicide (feminicidio) and femicide (femicidio) in Mexico and Nicaragua, two countries in which feminists engaged in legal activism to increase state accountability for gendered violence. Through comparative analysis, we demonstrate the importance of (1) the interaction between shifting local political conditions and supranational opportunities and (2) the position of feminist actors vis‐à‐vis the state and its gender regime in shaping regional variation in the making of laws concerning gendered violence. In Mexico, the criminalization of feminicidio resulted from a successful naming and shaming campaign by local feminist actors linked to litigation in various supranational arenas, and the intervention of feminist federal legislators. In Nicaragua, the codification of femicidio resulted from the state's selective responsiveness to feminist demands in a moment of narrow political opportunity within an otherwise highly consolidated regime. We also examine the unmaking of these laws through their perversion in practice (Mexico) and their intentional undermining (Nicaragua) at the hands of the state. Our analysis demonstrates how states' decisions to enact legislation against gendered violence does not occur solely because they are invested in international legitimacy, but also in response to states' shifting acceptance of the legitimacy of supranational authority itself. 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

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

The important findings of the International Crime Victim Survey (ICVS) have led the organisers to attempt to expand the scope of research to address the problem of victimisation of businesses through a specific international survey. Further to a first international survey in eight countries in 1994, the questionnaire was revised to focus in particular on the issues of corruption, fraud and extortion. The International Crime Business Survey (ICBS) was conducted in nine central–eastern European capital cities in 2000. The article presents a comparative analysis of experiences and attitudes of businesses in central–eastern Europe, where possible with reference to comparable information collected through the international households survey (ICVS) in the same cities and at the same time. Although there is great potential in this type of international research, too few resources are involved in analysing the results and looking at possible policy implications.The opinions expressed in this paper are those of the author and do not necessarly reflect the views of the United Nations 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
