体视学技术在医学影像学中的应用及其法医学价值

基于Cavalieri原理的体视学技术经常运用在组织学和病理学的研究中,但是现在,这种技术已经被运用于医学影像学(如CT、MRI、ECT、超声等)的测量。体视学的方法提供了一个非侵入性的、精确的、无偏的、简单的和快速的测量方法。所以该方法在医学影像学的形态计量学的测量中有临床使用价值。而影像资料的定量测量结果则有助于法医学实践。     

Mechanisms of the ‘Aid Curse’: Lessons from South Korea and Pakistan

Recently scholars have argued that, far from contributing to development, foreign aid hinders development. But in the 1960s the East Asian countries developed rapidly despite receiving large amounts of aid. To examine why aid seems to undermine development in some cases but not in others, we conduct a detailed comparison of the mechanisms of the ‘aid curse’ in South Korea and Pakistan. We show that South Korea saw astonishing levels of corruption, but this did not hinder its development; and Pakistan had a strong bureaucracy, which did not help it to grow. The key difference between the two countries was in the strength of their tax systems: foreign aid in the context of underdeveloped tax administration leads to increasing cycles of debt that undermine development. When foreign aid arrives in the context of commitment to strong taxation, a country can avoid the ‘aid curse.’     

In Defence of Substantial Sentencing Discretion

This article develops an ideal of sentencing discretion as consisting in sufficient dispositional flexibility for the trial judge to set, on behalf of the polity, reasonable terms for the continuance of relations with the offender in view of his crime. This ideal requires trial judges to have what may be termed “substantial” sentencing discretion: discretion that is exercised with direct reference to the values and goals penal sanctions are expected to serve, and where it is this quality of value-based engagement that provides the justification for the decision. The article engages with empirical research into sentencing that helps us address the strength of the case for and against substantial sentencing discretion, and ultimately defends substantial sentencing discretion on functional as well as ethical–political grounds.     

Polymorphism of the third component (C3) of complement and of Transferrin (Tf) in Belgium.

The phenotypes of C3 and of Tf were determined in 818 and 576, respectively, unrelated individuals living in Liege. The gene frequencies observed are: (formula: see text) The application to disputed paternity cases and to the study of twins is discussed.     

A comparison between neural network and other metric methods to determine sex from the upper femur in a modern French population

Forensic anthropologists are frequently asked to assess partial or badly damaged skeletal remains.One such request led us to compare the predictive accuracy of different mathematical methods using four non-standard measurements of the proximal femur (trochanter–diaphysis distance (TD), greater–lesser trochanter distance (TT), greater trochanter width (TW) and trochanter–head distance (TH)). These measurements were taken on 76 femurs (38 males and 38 females) of French individuals. Intra- and inter-observer trials did not reveal any significant statistical differences. The predictive accuracy of three models built using linear and non-linear modelling techniques was compared: discriminant analysis, logistic regression and neural network. The neural network outperformed discriminant analysis and, to a lesser extent, logistic regression. Indeed, the best results were obtained with a neural network that correctly classified 93.4% of femurs, with similar results in males (92.1%) and females (94.7%). Univariate functions were less accurate (68–88%). Discriminant analysis and logistic regression, both using all four variables, led to slightly better results (88.2% and 89.5%, respectively). In addition, all the models, save the neural network, led to unbalanced results between males and females. In conclusion, the artificial neural network is a powerful classification technique that may improve the accuracy rate of sex determination models for skeletal remains.
