  • Drugs and Driving

    • 1 Edición
    • Herbert Moskowitz
    • Inglés
    Drugs and Driving is a compendium of papers from a symposium of the same title presented at the U.S. Transportation Research Board. This collection reviews the effects of five classes of drugs on driving (amphetamines, tranquilizers, barbiturates, narcotics, cannabis), the other studies being made on drugs and driving, as well as some countermeasure programs against drunk driving. The papers report that amphetamines can induce risky driving behavior, tranquilizers can increase traffic accident risks, barbiturates can degrade driving skills especially when the drug is combined with alcohol, while marijuana use can impair important driving skills. Another paper evaluates drug use and driving risk among high school students in Toronto: results show that the total effect of infrequent use of drugs on accidents is small compared to alcohol use. A study of out-patients in Finland notes that the combined used of alcohol and drugs tend to increase accident frequency. One paper refutes that Alcohol Safety Action Programs in the United States are ineffective. This collection can be helpful for sociologist, psychologists, psychiatrists, traffic safety officers, and heads of urban safety and traffic divisions.

    • J. Tinbergen
    • Inglés
    The reform of the Common Agricultural Policy (CAP) which is now being implemented, reduces the support for a selected number of agricultural products. This book uses welfare theory and applied general equilibrium analysis to assess the medium to long term consequences of this reform, if the new policies remain in place until the beginning of the next century. It analyses the implications of two alternative scenarios: a) a further trade liberalisation covering all commodities; and b) increased protectionism with high prices, constraints on production and export subsidies (financed by the farmers themselves). The study also investigates the implications of financial renationalisation, whereby the European Union member-states would cover the costs of their own support measures.

    Additive Migration from Plastics Into Food examines the intrusion of foreign chemicals into food via additives present in plastics packaging and the toxic hazards they pose to consumers. This book shows how direct contact between the packed commodity and the plastic is likely to result in the transfer of polymer additives, adventitious impurities such as monomers, catalyst remnants, and residual polymerization solvents, and low-molecular-weight polymer fractions from the plastic into the packaged material. This book is comprised of nine chapters and begins with a discussion on the various types of plastics used in food packaging as well as the types of substances present in the plastic that might migrate into the food. Subsequent chapters review world literature on extraction testing and the analysis of extractants. The determination of various types of polymer additives and residual monomers in extractants of liquid foodstuffs and beverages, solid foods, edible oils, and fatty foodstuffs is considered. The final chapter looks at the legal requirements concerning the use of additives in food-grade plastics in various countries. This monograph will be of interest to those in the plastics industry, food and beverage packaging industry, and large retail outlets such as supermarkets, along with medical and public health officials, legislators, environmentalists, and the general public.
