Tracing is generally understood to be the process of following value through one or more substitutions, by which a claimant ‘transmits’ his claim from the right substituted into its exchange product. Understood thus, the exercise of tracing has been made increasingly difficult to conduct and predict by the development of complex payment mechanisms involving multiple payment instructions and interceding periods of indebtedness. This article argues that concepts of value are conceptually and practically misleading. Identifying and determining the content of transactions are normative processes that depend, not upon identifying the precise mechanisms by which a particular change in legal relations is sought and executed, but rather upon the manifested intentions of the transacting parties. This allows us to deal straightforwardly with complex payment structures, clearing and credit, and to focus instead upon the role of transactions in the justification for a resulting claim.  相似文献

This article analyzes the 2008 Colombia–Ecuador armed crisis in the light of the practice of targeted killings and incursions against non-state actors harbored at terrorist safe havens in a third party state. The Colombian use of force against Fuerzas Armadas Revolucionarias de Colombia (Revolutionary Armed Forces of Colombia—FARC) is discussed in the context of use of force in International Law regarding the right of self-defense against non-states actors and third state parties’ obligation to deny passive support. It is argued that the Colombia situation is similar to the situation faced by Israel and Turkey.  相似文献

Practitioners and scholars of postcommunist politics disagree on the accomplishments of administrative reforms in new Eastern European democracies. The transformation of the public sector after 1989 has aimed to consolidate the democratic process and enhance economic development. Skeptics, however, argue that administrative reforms face serious challenges in the context of economic liberalization, insufficient capacity for modernization, and cultural legacies of the past. The authors judge reform effectiveness by testing the impact of civil service reform on government transparency and foreign direct investment. The results of the empirical analysis confirm that once reform is adopted, administrations become more effective at reducing corruption and attracting investment. Despite the delays and difficulties of implementation, the adoption of reform is important in and of itself, and countries can expect positive results sooner than skeptics predict.  相似文献

A set of 61 Y chromosome single-nucleotide-polymorphisms (Y-SNPs) is typed in a sample of 2517 individuals from 38 populations to infer the geographic origins of Y chromosomes in the United States and to test for paternal admixture among African-, European-, Hispanic-, Asian-, and Native-Americans. All of the samples were previously typed with the 11 core U.S. Y chromosome short tandem repeats (Y-STRs) recommended by SWGDAM, which revealed high levels of among ethnic group variation and low levels of among-population-within-ethnic-group variation. Admixture estimates vary greatly among populations and ethnic groups. The frequencies of non-European (3.4%) and non-Asian (4.5%) Y chromosomes are generally low in European-American and Asian-American populations, respectively. The frequencies of European Y chromosomes in Native-American populations range widely (i.e., 7-89%) and follow a West to East gradient, whereas they are relatively consistent in African-American populations (26.4+/-8.9%) from different locations. The European (77.8+/-9.3%) and Native-American (13.7+/-7.4%) components of the Hispanic paternal gene pool are also relatively constant among geographic regions; however, the African contribution is much higher in the Northeast (10.5+/-6.4%) than in the Southwest (1.5+/-0.9%) or Midwest (0%). To test for the effects of inter-ethnic admixture on the structure of Y-STR diversity in the U.S., we perform subtraction analyses in which Y chromosomes inferred to be admixed by Y-SNP analysis are removed from the database and pairwise population differentiation tests are implemented on the remaining Y-STR haplotypes. Results show that low levels of heterogeneity previously observed between pairs of Hispanic-American populations disappear when African-derived chromosomes are removed from the analysis. This is not the case for an unusual sample of European-Americans from New York City when its African-derived chromosomes are removed, or for Native-American populations when European-derived chromosomes are removed. We infer that both inter-ethnic admixture and population structure in ancestral source populations may contribute to fine scale Y-STR heterogeneity within U.S. ethnic groups.  相似文献

The increasing demand for rapid methods to identify both inorganic and organic gunshot residues (IGSR and OGSR) makes electrochemical methods, an attractive screening tool to modernize current practice. Our research group has previously demonstrated that electrochemical screening of GSR samples delivers a simple, inexpensive, and sensitive analytical solution that is capable of detecting IGSR and OGSR in less than 10 min per sample. In this study, we expand our previous work by increasing the number of GSR markers and applying machine learning classifiers to the interpretation of a larger population data set. Utilizing bare screen-printed carbon electrodes, the detection and resolution of seven markers (IGSR; lead, antimony, and copper, and OGSR; nitroglycerin, 2,4-dinitrotoluene, diphenylamine, and ethyl centralite) was achieved with limits of detection (LODs) below 1 µg/mL. A large population data set was obtained from 395 authentic shooter samples and 350 background samples. Various statistical methods and machine learning algorithms, including critical thresholds (CT), naïve Bayes (NB), logistic regression (LR), and neural networks (NN), were utilized to calculate the performance and error rates. Neural networks proved to be the best predictor when assessing the dichotomous question of detection of GSR on the hands of shooter versus nonshooter groups. Accuracies for the studied population were 81.8 % (CT), 88.1% (NB), 94.7% (LR), and 95.4% (NN), respectively. The ability to detect both IGSR and OGSR simultaneously provides a selective testing platform for gunshot residues that can provide a powerful field-testing technique and assist with decisions in case management.  相似文献

This article examines how gender hierarchies are (re)created within the context of northern landscapes. We analyse data from fieldwork and interviews with middle-class female Russians having settled in a small town in northernmost Norway, most of them as marriage migrants. Inspired by the phenomenology of the body, feminist phenomenology and gender theory, the analysis shows how the participants talk about nature as ‘recreation’ and ‘poetry’, but also as a venue that is vital for (re)shaping their gendered identities. In particular, the Russian women talk about their strong, skilful outdoors Norwegian husbands as ‘experts’ in nature, and about themselves as ‘novices’. This ‘expert–novice’ relationship creates a hierarchical distinction between the Norwegian man and the Russian woman, but also attributes additional value to the equality-oriented, but in several cases neither highly educated nor highly paid, Norwegian husband. Through this ‘re-masculinisation’ of their Norwegian partners, the Russian women create a complementary, but subordinate space for themselves. The analysis reveals that our participants situate themselves in contrast to the Norwegian equality ideal while creating a room of their own where they can form a separate and unique Russian femininity. This illustrates how constructions of gender are interwoven in translocal ‘minoritising’ and ‘majoritising’ processes.  相似文献
