Radiographs of 277 living individuals were assessed via a numerical scoring system to determine the timing of appearance and degree of fusion between the proximal epiphysis of the fifth metatarsal and its diaphysis. The epiphysis was observed to first appear in females at 8 years and 10 years in males and fuse by 14 years in females and 15 years in males. When assessing the level of agreement of category assignment, inter‐observer agreement was 78% for females and 64% for males whereas intra‐observer agreement was 77% for females and 86.1% for males. These results suggest that the maturation of the proximal epiphysis of the fifth metatarsal may be of value in age estimation in the child and that the scoring system is sufficiently robust to merit continued investigation. Previously this epiphysis has been considered an inconstant feature, but this research confirmed its presence in all individuals studied.  相似文献

An analysis of the ways in which different composite monarchies conducted international relations in the eighteenth century reveals the interplay of structure and contingency in shaping change and the discussion of change. Hanover-Britain is compared with Saxony-Poland. Considering Britain as an example of a polity created and shaped by a dynastic personal union redresses teleological tendencies in the treatment of international relations and offers an important perspective.  相似文献

Despite the promising advances in the construction and use of social indicators, there has been little application to the formulation, monitoring, or evaluation of foreign policy. In the formulation stage—our concern here—predictor or early warning indicators could be very useful. The annual state of the world message contains many such predictive indicators of war, but in a purely verbal and intuitive form. Three of these (prior war, relative capabilities, and alliance levels) are converted into operational language and then put to the empirical test. In general, the indicators do not predict war (over the past 150 years) as postulated by the Administration. These tests are, however, very incomplete, and our objective is not to evaluate the Administration's arguments, but to suggest one way in which indicators could improve the quality of foreign policy formulation.This is a revised and abbreviated version of the paper originally prepared for the 1972 meetings of the American Political Science Association held in Washington, D.C. We want to acknowledge the important assistance of Hugh Wheeler, the comments and help of John Stuckey, Russell Leng, Stuart Bremer, Catherine Kelleher, and Charles Gochman, and the support of the National Science Foundation under grant no.
