The estimation of stature from of a variety of bones is an important aspect of forensic work. In order to obtain reliable results, it is important to have comparative data obtained from the same population group as the skeletal remains. However, lack of up to date information on the population groups of Southern Europe makes the estimation of stature from bones in this area subject to possible error. In this study, the stature of 104 healthy adults from Spain was measured, and an anteroposterior teleradiograph of the right lower and the right upper limb of every subject in the study was made in order to measure the lengths of the femur, tibia, fibula, humerus, cubitus and ulna. Pearson's regression formulae were obtained for both limbs. In males, we found the femur to be the most accurate predictor of stature (R = 0.851), whereas in females best results were obtained with the tibia (R = 0.876). 相似文献
China launched an ambitious strategy known as the Belt and Road Initiative (BRI) in 2013 with an objective to promote regional economic growth and integration. The initiative was implemented primarily through massive investment in transportation infrastructure development among the Belt and Road countries to improve transportation connectivity and reduce trade costs. While such a strategy has been implemented for more than seven years, it remains unclear to what extent the investment of transportation infrastructure has affected the regional economic performance in various countries. To clarify this question, this study provides an in-depth assessment of BRI investment in transportation infrastructure using a computable general equilibrium (CGE) model. Different from previous studies, the regional economic impact was evaluated through CGE simulations based on the actual investment data obtained from various sources. In addition, both the change of intraregional and interregional trade costs as a result of BRI transportation infrastructure investment was estimated. The results show that the transportation infrastructure investment in BRI has generated different impacts among regions. In particular, China, Central and West Asian countries have gained significant growth in GDP, employment, and economic welfare, whereas the economic impact of transportation infrastructure investment in the Central and West Europe is relatively minor. Overall, the research findings provide important policy implications for future transportation infrastructure investment in BRI countries and beyond.
