ABSTRACTBringing peace, security, and stability to the war-torn region of Donbas has proven to be a challenging – some would say near-impossible – task. The “Minsk II” agreement, signed in February 2015, was supposed to put an end to the armed hostilities, resolve the underlying political issues, and gradually restore Ukrainian government control of the country’s eastern border. None of this has happened. Despite continuous Western support and pressure, progress in the implementation of the peace plan signed in Minsk has been slow, also after the much-anticipated Paris summit of the “Normandy Four” (Russia, Ukraine, Germany, and France) in December 2019. This article discusses the underlying causes of the current stalemate, emphasizing factors such as the inherently complex nature of the conflict, the process through which “Minsk II” came into being, the vague and ambiguous language of this and other agreements, practical challenges related to the timing and sequencing of agreed-upon measures, and Russia’s persistent non-acknowledgement of its role in the conflict. 相似文献

The 17 Y-chromosomal short tandem repeats (STRs) included in the AmpFLSTR Yfiler PCR Amplification Kit (AB Applied Biosystems) (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4) were typed in two Berber communities, a small village (Takrouna) and a town (Sejenane), from North Tunisia. As expected, diversity was higher in the town, even when compared with a pool of three small Berber communities, probably due to the combination of different founder effects and genetic drifts operating in the small villages. 相似文献

Declining trust in representative institutions is considered one of the most significant political problems of our time. It is often suggested that democratic innovations—or mechanisms which aim to increase and deepen citizen participation in the political decision-making process—can help reverse this trend. However, empirical research about actual effects of participation on trust is scarce, and weakened by causality problems. With survey data representing 1,470 participants in a landmark Swedish e-petition system, the article shows that both generalized attitudes and process evaluations matter in how trust is affected by democratic innovations. 相似文献

This talk was originally given at Mount Saint Vincent University (Halifax, Canada), a women's university going co-educational, and with predictable results. It was ‘regiven’ in Gröningen—by ‘popular request’ and it contains the main reasons that women need a feminist University. 相似文献

We suggest the use of the mismatch distribution methodology as an easy way to estimate the distance between all pairs of haplotypes present in a sample. This approach allows the evaluation of the proportion of pairs of Y-STR haplotypes that are prone to become identical by state (IBS), in one generation, by recurrent mutation, a statistic of major importance in the forensic field. The mismatch approach presents some advantages alternatively to the empirical one, since it is not necessary to have simultaneous information on STRs and SNPs, and it allows the evaluation of IBS also within-haplogroups. The estimation of IBS at an European scale showed that there is a high population substructuring for this parameter, increasing from southern-central European countries towards west and north, in accordance to what was found for Y-biallelic markers. This result seems to imply a more careful use of large databases for matching evaluation, even in the absence of population structure for general Y-STR diversity. Furthermore, mismatch distribution can be used to measure the distance between a particular haplotype and all the haplotypes in a sample. When applied to the most frequent haplotypes in Europe it revealed that the opportunity for IBS is not directly related to the frequency of a haplotype, but highly dependent on the proportion of neighbouring haplotypes--so, that reporting on the haplotype frequency for evaluating the significance of a match can be misleading. 相似文献

Pros and cons in the use of SNPs in forensic kinship investigation: a comparative analysis with STRs 总被引:4,自引:0,他引:4
Recent advances in single nucleotide polymorphisms (SNPs) research have raised the possibility that these markers could replace the forensically established short tandem repeats (STRs). In this work, we compare STRs and SNPs applicability for kinship investigation in terms of expected informative content and probability of occurrence of "difficult cases" (when isolated Mendelian incompatibilities between alleged father and child are found). Since SNPs have a much lower mutation rate than STRs, these difficulties were expected to occur less frequently if SNPs were used instead of STRs. The purpose of this paper is to make some simulations allowing the estimation of how often such difficult cases are expected to occur using both types of markers and how serious can be their impact in routine work. Our results demonstrate that a battery based exclusively on SNPs matching the informative power of current STR kits would be prone, if applied to routine paternity investigation, to the occurrence of cases where the statistical evidence would be inconclusive. We infer that the introduction of a SNP based strategy, as a substitute to the now classical STR approach poses statistical problems that must be carefully evaluated. 相似文献

What impact does European Union (EU) funding of advocacy organizations have? To address this question our article turns to the post-communist Czech Republic, an ideal laboratory for studying externally dependent non-governmental organizations. Employing social network analysis, the main objective of this article is to analyse the effect of EU funding on the cooperation networks of Czech advocacy organizations. Our source of data is a survey of these organizations. We aim to figure out whether there is an association between the dependency of advocacy organizations on EU resources, and their cooperation with other organizations. Contrary to the prevailing interpretation based on the competition argument, our hypothesis is that the greater the dependency on EU funding, the greater the cooperation capacity on the part of advocacy organizations. 相似文献
