The aims of this study were to enable geometric morphometric sex classification using tibial proximal and distal sexual dimorphism and to evaluate the secular trend of tibial shape/form from the early 20th century to the present day. The study samples consisted of 61 adult tibias from an early 20th‐century Czech population and 57 three‐dimensional tibias from a 21st‐century population. Discriminant function analysis with cross‐validation was carried out to assess the accuracy of sex classification. Shape analysis revealed significant sex differences in both tibial extremities of the 21st‐century sample and in the proximal tibia of the 20th‐century population. Sex‐based divergence varied between the analyzed samples, raising the issues of population specificity and diachronic change. Classification using tibial form was more successful than using tibial shape. The highest values of correct assignment (91.80% and 88.52%) were found using the form from the early 20th Czech population. 相似文献

Paradoxes of Family Immigration Policy: Separation,Reorganization, and Reunification of Families under Current Immigration Laws

It is increasingly recognized that immigration laws affect immigrants' integration. Most recently there has been growing attention to how immigration enforcement affects families through forced separations caused by deportations and long‐term family separations across national borders stemming from unauthorized entry to the United States. However, beyond enforcement, there has been little systematic account of how other provisions of immigration law contribute to family separations. In this article we examine how four key provisions in immigration law, far from creating conditions for immigrant families to reunite, contribute to keeping families apart. As such, these provisions shape, in fundamental ways, the structure and composition of immigrant families. Relying on data from the American Community Survey and ethnographic interviews in Phoenix, Arizona, we find evidence consistent with the premise that immigration laws affect the formation, composition, and structure of immigrant families with potential long‐term consequences. 相似文献

This article analyzes the marriage boom that took place during the middle decades of the twentieth century. The increase in nuptiality is analyzed in Spain and Sweden from a qualitative perspective, and the authors describe how cultural, social, economic and institutional transformations were understood by women who were in their reproductive period during the marriage boom. In-depth interviews were conducted in both places with 51 women born between 1919 and 1951. The authors argue that it is important that the ways in which the factors previously identified as decisive of the marriage boom are studied for their motivating power, and the way they were or were not made important in people's understandings of their marital practices. The results show that despite the differences between the national contexts of Spain and Sweden, three interrelated themes recurred when the interviewed women framed their marital choices: (1) the normalization of marriage as a life event; (2) religion; (3) and education and work life. The results also suggest that the women highlighted norm systems within which their choices and decisions were made, rather than describing individual choices and decisions as stemming from individual preferences and wishes. 相似文献

This article is about how political regimes should generally be classified, and how Latin American regimes should be classified for the 1945–99 period. We make five general claims about regime classification. First, regime classification should rest on sound concepts and definitions. Second, it should be based on explicit and sensible coding and aggregation rules. Third, it necessarily involves some subjective judgments. Fourth, the debate about dichotomous versus continuous measures of democracy creates a false dilemma. Neither democratic theory, nor coding requirements, nor the reality underlying democratic practice compel either a dichotomous or a continuous approach in all cases. Fifth, dichotomous measures of democracy fail to capture intermediate regime types, obscuring variation that is essential for studying political regimes. This general discussion provides the grounding for our trichotomous ordinal scale, which codes regimes as democratic, semi-democratic or authoritarian in nineteen Latin American countries from 1945 to 1999. Our trichotomous classification achieves greater differentiation than dichotomous classifications and yet avoids the need for massive information that a very fine-grained measure would require. 相似文献

This paper looks at the field of information technology (IT) law and its reliance on the buzzwords, jargon and acronyms that tend to alienate serious discussion about some of the deeper socio‐legal issues involved. It is often easy to become confused by the terminology and the technology, which has led to some non‐issues receiving too much interest (the year 2000 bug for example) and some valuable and worthy topics being almost ignored. Some writers and researchers may be tempted to neglect the field because of a lack of understanding of the technology, which may eventually lead to the end of IT law as a serious field of research. This paper will attempt to re‐ignite the jurisprudential debate about the future of IT law research, teaching and practice by looking at the possible trends emerging from the literature. 相似文献
