The extent of aspartic acid racemization in dentin: a possible method for a more accurate determination of age at death?

In the current study the objective was to find to what extent a reliable determination of age at death is made possible by establishing the degree of aspartic acid racemization in the dentin of teeth. The results of the investigation of 46 teeth are in agreement with the values found by other authors. The method presented makes a reproducible and accurate estimation of age possible. We intend to elaborate and improve this promising method for determination of age at death. The relevant points are presented here.     

Antitrust in China: The Problem of Incentive Compatibility

This paper reviews China's recent efforts to enact a competitionpolicy (antitrust) law. We focus on three issues: (1) What isthe substance of the proposed law, and how does it differ fromexisting antitrust law in other countries, (2) How will thelaw be implemented or enforced, and how will those who mustimplement this law interpret their mandate, and (3) What willbe the likely effects of this law given China's unique historyand cultural heritage. We emphasize China's economic, legaland regulatory contexts in which an antitrust law may be enforced.Our central focus is the problem of establishing a substantiveand procedural legal framework that is incentive-compatiblewith economic efficiency and growth. The draft law could beimproved, both to increase its clarity and to make its enforcementmore consistent with the goal of achieving improvements in economicefficiency. Nevertheless, there is much merit in the draft,especially its strong focus on reducing anticompetitive practicesof state-owned enterprises (SOEs) and other government bodies.However, our major difficulty with the new law is that, in theabsence of a tradition of reliance on the rule of law, Chineseand foreign enterprises will find it very difficult to relyon the antitrust statute or the actions of the courts in Chinaas a basis for predicting the antitrust liability that mightresult from various business practices. Therefore, the principalvector by which antitrust law (or indeed any law) affects economicbehavior is absent from the Chinese scene. Unless the bureaucracythat enforces the new antitrust law actively pursues a policyof consistent enforcement based on written guidelines, staredecisis, or other sources of predictability, the substance ofthe statute itself will have little significance. That outcomewould represent a significant loss for the economic welfareof the Chinese people.     

Fertility and migration in the heart of the industrial revolution.

This study examines demographic growth and change in Tilleur in the valley of Meuse in Belgium during 1807-80 during the process of industrialization and urbanization. The proportion of immigrants (foreigners and Flemings) increased from 15% in 1807 to 65% in 1856. After 1856, population and industrial growth stabilized. During 1856-66 the proportion of natives stabilized, and the proportion of Flemings increased. It is argued that in Tilleur there were two phases: a foundation phase of industrial and population growth and a phase of maturation with decreased non-native population and greater similarity between groups. Immigrants contributed to the birth rate in greater proportions than their proportion in the population of Tilleur. During 1847-66 native population increased annually from 2.4% to 3.8%. Migrants' annual increases were diminished by the effects of mortality but expanded by the influence of in-migration. During 1857-66 the proportion of foreigners declined and marked the transition to a new phase. During 1830-66 the sex ratio grew from 93 to 119. During the Industrial Revolution in Tilleur, women shifted from outnumbering to undernumbering men. The iron and coal in the region attracted men. The sex ratio among the Flemish was 214 in 1866. In 1830 the proportion of fertile women was higher among immigrants and declined thereafter. Age at marriage rose for natives and declined for immigrants. The native population structure by sex, age, and marriage did not favor the birth rate. During 1866-80 the birth rate of foreign immigrants and rural natives declined, the birth rate of natives doubled, and the gap between these two groups narrowed. The changes among immigrants during the foundation phase led to fertility decline in the maturation phase. Marriage and migration interactions linked the industrial revolution with the demographic transition.     

Wilton Marion Krogman, Ph.D. (1903-1987): the end of an era

Dr. Wilton Marion Krogman was one of the major founders of physical and forensic anthropology in the United States. His extraordinary career spanned nearly six decades, and he was universally admired and respected for his scholarship, teaching, research, wit, and humanity. While studies based on human skeletal remains have long been used to assist the medicolegal system, the late Dr. Krogman can be credited with uniting these areas into the discipline of forensic anthropology. His "Guide to the Identification of Human Skeletal Material" (1939) in the F.B.I. Law Enforcement Bulletin became the foundation of this discipline; his monumental book The Human Skeleton in Forensic Medicine (updated with the author in 1986) solidified its establishment. The purpose of this paper is to pay tribute to this great man and outline his influence on the development and advancement of forensic anthropology.     

Is medical care different? Old questions, new answers

This paper examines whether changes in medical markets may be making them more like other markets. The emergence of HMOs and other managed care systems appears to have increased the consumer's potential ability to make better comparative judgments about the price and quality of medical care, and also seems to have made medical care more like other goods. However, the evidence that medical care is a "reputation good" suggests that it is, in this respect, different from other goods. Finally, the social concerns about medical care use necessarily make medical care different.
