Summary

Comments on the Introduction and Application of French Law in the Netherlands in the Years 1810–1813

A consequence of the annexation of the Netherlands by the French Empire in 1810 was the sudden introduction of French legislation. That led to a number of problems, as the documents in the archives reveal. However, the years of annexation had a considerable influence on the subsequent legislation of the Kingdom of the Netherlands for the last laws dating from that period were not abolished until January 1st, 1970.  相似文献

In the domain of environmental security, it appears that a strong civil society, one with strong social ingenuity and social capital, is a necessary condition not only for environmental security, but also for regional security in general. This paper will argue that in the context of the Association of Southeast Asian Nations (ASEAN), much can be learned from the empirical experiences of Thailand and the Philippines that have established records of accomplishment in civil society participation in forest governance. Also discussed is the possible role of epistemic communities both within these countries as well as across countries in the ASEAN in harnessing institutions of knowledge to influence domestic and regional governance of forest resources.  相似文献

The polymorphism of nine STR loci has been studied in a sample of 598 individuals from the population of Alagoas, Northeastern Brazil. Determination of the allele frequencies as well as of several commonly used statistics in forensic and paternity testing were defined. The most polymorphic loci were TH01 and D7S317. The exact test demonstrated that the nine loci analyzed in the population have no deviation from Hardy–Weinberg equilibrium (P>0.05).  相似文献

This paper is a case study of Eastern European immigrant women's social inclusion in Portugal through civic participation. An analysis of interviews conducted with women leaders and members of two ethnic associations provides a unique insight into their migrant pathways as highly educated women and the ways in which these women are constructing their citizenship in new contexts in Northern Portugal. These women's accounts of their immigrant experience embrace both the public realm, in using their own education and their children's as a means of integration but also spill over into ‘non-public’ familial relationships at home in contradictory ways. These include the sometimes traditional, gender-defined division of labour within the associations and at home and the new ways that they negotiate their relative autonomies to escape forms of violence and subordination that they face as women and immigrants.  相似文献

The extraction of DNA from human skeletal remains applied to forensic, and evolutionary studies do not exclude risks, which are to be evaluated when working with unique specimens that could be damaged or even destroyed. In the present study were evaluated several nondestructive methods for recovering DNA instead of the most currently used pulverization method. Three different procedures to access inside the dental pieces (occlusal perforation, cervical perforation, and cervical cut) have been compared with the aim of recovering as many cell remains as possible to carry out a DNA extraction. Given the DNA quantitation results, a method was proposed that consists of a cervical cut to facilitate the access to the pulp cavity and a subsequent filing of the root canals down to the apex of the dental root. This methodology allows the recovery of both mitochondrial and nuclear DNA, with the minimum deterioration for the dental pieces.  相似文献

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.  相似文献
