Traffic accidents and drivers suspected for drug influence

All records from the Danish Medicolegal Council concerning drivers suspected for drug influences were examined for the 5 year period 1981-1985. 461 records were included, 62 women and 399 men. In 250 cases drugs from more than one of ten groups had been taken thus making 786 combinations of drug/driving. The major drug group was benzodiazepines, accounting for 65% of all drug intake. Opioids also contributed substantially, found in 38% of the cases. A traffic accident had occurred in 180 (39%) of the records. Drivers who had been taking antidepressives were involved in an accident in 67%, significantly above the mean. For benzodiazepines, the corresponding percentage was 43%, while for opioids it was only 23%, significantly below the mean. This striking difference has been demonstrated in most of the studies concerning drugs in traffic. It may support the hypothesis that opioids do not necessarily make driving dangerous, as do antidepressives, barbiturates and especially benzodiazepines.     

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.     

The effect of authority and social influence on eyewitness suggestibility and person recognition

This study investigated the influence of an authority figure on eyewitness identification. Participants watched a staged crime and then were administered a photo lineup by either an authority (policeman) or non-authority figure (civilian). Participants in the authority condition were more likely to choose a lineup member than those in the non-authority condition. There was no effect of authority, however, on the accuracy of the identification decisions. The lack of a deleterious effect suggests that the presence of a police officer during identification procedures does not create an unduly suggestive situation or have undesirable effects on eyewitness identification decisions. Although witnesses' choosing behaviors did not increase the rate of identification errors, the effect of the administrator's authority on choosing was reduced when unbiased instructions (vs. biased instructions) were presented to the witnesses. Thus, support was found for the use of neutral instructions during eyewitness identification procedures.
