A better approach by management in drug testing

Discussed here are a number of drug abuse and drug testing issues. This article presents an overview of current developments in the area of drug testing in the workplace. There is an analysis of legislation, federal and state court decisions, and key legal arguments. These decisions and arguments are discussed in the context of employee rights and responsibilities. Also presented are the legal and ethical aspects of drug testing in the workplace. The authors make a case for a rehabilitative rather than a punitive approach to employee drug abuse.     

Tax Reform and Organizational Forms for Holding Investment Real Estate: Corporation vs. Partnership

Following the ERTA of 1981, partnership ownership of real estate dominated corporate ownership. This study concludes that the Tax Reform Act of 1986 provides incentive for holding real estate investments that produce sizable tax losses and/or that are eligible for large tax credits in corporate rather than partnership form. Perpetuity cash flow models are employed initially to identify key tax and cash flow variables favorable to each organizational form. The perpetuity assumption is then relaxed to consider a more representative real estate investment. A sensitivity analysis examines the extent to which the base case results are dependent on the assumed values of selected model parameters.     

Improved use of fisheries resources : Alleviating malnutrition in Southern Africa

The author reviews the potential for improved use of fisheries resources in nine southern African countries. These countries have serious problems of malnutrition and the author concludes that fisheries resources could make a substantially greater contribution to nutrition. Supply, processing and distribution of fisheries products are reviewed, and the benefits of improved kapenta and aquaculture production are discussed.

FURTHER ANALYSIS OF THE PUT-CALL PARITY IMPLIED RISK-FREE INTEREST RATE

In this paper the put-call parity implied riskless rate of borrowing and lending is re-examined. Using a rigorous model, it is shown that, given the level of an observable proxy of the risk-free rate of lending (T-bill rates, for example), the put-call parity provides an opportunity to borrow at rates substantially below the market rate of lending. This is especially true when high interest rates prevail. The major conclusion is either that American option prices may invalidate the parity, or that option markets are not as frictionless as one might wish.     

Bricks and Behavior: The Repair and Maintenance Costs of Housing for Persons with Mental Illness

Comprehensive data on 153 properties offering independent living for persons with mental illness are used to examine the effects on repair and maintenance (RM) costs of building quality, neighborhood quality, building size, proportion of tenants with mental illness, and management experience with mentally ill tenants. We find an inverted U-shaped relationship between the proportion of mentally ill tenants in a building and its RM costs, which suggests favorable behavioral effects on mentally ill tenants of living in the same building with others who are mentally ill. We also find amenity features are associated with higher RM costs in properties where more tenants are mentally ill.     

Optimal abatement of sulphur emissions in Europe

This study presents a mathematical model for determining cost-effective emissions' control strategies in Europe, by minimizing sulphur abatement costs subject to different pollution control targets. The purpose is to compare the efficiency of a uniform percentage emissions reduction with a scenario that takes variation in environmental conditions into account. Underlying the proposed model is the belief that a full cost-benefit analysis of acid rain abatement is infeasible. The model focuses on the costs of abatement and provides an estimation of the gains (or losses) that countries could achieve if they co-operate in their policies rather than act independently.
