Contemporary liberal states are eager to combat ‘human trafficking’, which state actors describe as ‘the scourge of modern slavery’ and a violation of human rights. The same states are also depriving migrants of their freedom on an unprecedented scale through immigration detention, forcibly moving them across borders through deportation, and sustaining a flourishing industry in the prevention and control of human movement. This is not a paradox. The ambition to eradicate ‘slavery’, as much as the desire to severely restrict freedom of movement, reflects a concern to preserve and extend state powers, in particular its monopoly on violence and on the control of mobility. 相似文献

ABSTRACTThis article presents an analytical framework that guides the contributions to this special issue and, in general terms, aims at enabling a systematic investigation of processes of negotiation in the international promotion of democracy. It first briefly introduces the rationale for studying democracy promotion negotiation, offers a definition, and locates the general approach within the academic literature, bringing together different strands of research, namely studies of negotiation in international relations as well as research on democratization and democracy promotion. The larger part of the article then discusses key concepts, analytical distinctions and theoretical propositions along the lines of the three research questions that are identified in the introduction to this special issue. More specifically, the article (1) offers a typology that facilitates a systematic empirical analysis of the issues that are discussed in democracy promotion negotiations; (2) takes initial steps towards a causal theory of democracy promotion negotiation by identifying and discussing a set of parameters that can be expected to shape such negotiations; and (3) introduces key distinctions and dimensions that help guide empirical research on the output and outcome of negotiations in democracy promotion. 相似文献

This study evaluates population variation of eight cranial morphoscopic traits using samples of known southwest Hispanics (n = 72), Guatemalans (n = 106), American Blacks (n = 146), and American Whites (n = 218). We applied the support vector machine (SVM) method to build a prediction model based on a subsample (20%) of the data; the remainder of the data was used as a test sample. The SVM approach effectively differentiated between the four groups with correct classification rates between 72% (Guatemalan group) and 94% (American Black group). However, when the Guatemalan and southwest Hispanic samples were pooled, the same model correctly classified all groups with a higher degree of accuracy (American Black = 96%; American White = 77%; and the pooled Hispanic sample = 91%). This study also identified significant differences between the two Hispanic groups in six of the eight traits using univariate statistical tests. These results speak to the unique population histories of these samples and the current use of the term “Hispanic” within forensic anthropology. Finally, we argue that the SVM can be used as a classification model for ancestry estimation in a forensic context and as a diagnostic tool may broaden the application of morphoscopic trait data for the assessment of ancestry. 相似文献
