    Abstract. We have investigated the cusp resulting from electron capture to the continuum of 1.25-5 MeV m u- ' fully stripped hydrogen and oxygen as a function of the collision energy and the detector angular resolution B o. It is revealed that the characteristic cusp shape parameters depend strongly on the experimental resolution. Our experimental data are "pared with the second-order Born theory and the impulse approximation. Both theories mnhrm the 8, dependence of the shape parameters and gjve a reasonable descrip-lion of the cusp asymmetry. However, theory tends to overestimate the absolute cross sections, in particular in the case of oxygen. 1

    Environmental Benefits from Reduced Pesticide Use and Returns to Research: An Application to the U.S. Cotton Industry

    Get PDF
    Cotton production is one of the main pesticide use industries in the U.S. This intensive use has resulted in the disruption of naturally occurring biological control factors that regulate other insect pest populations and “the pesticide treadmill”. The result is resistance to insecticides, high control costs and unacceptable levels of chemical insecticides in the environment. Concerns about the environmental and human health effects from pesticide use thus need to be modeled in evaluation studies.Cotton, pesticide use, environmental effects, supply function, Crop Production/Industries, Environmental Economics and Policy,

    Family Recreation and the Single Parent

    The traditional family of the 50\u27s and 60\u27s is a rare find in the 1980\u27s. The 1980\u27s has been plagued with an increase in the divorce rate and a decrease in the marriage rate, resulting in the increase of single parents, blended families, serial marriages and selective childlessness. As we move into the 1990\u27s recreation professionals and volunteer agencies need to focus more on the single parents in their offerings. Recreation for the single parent is a rarity therefore, a lot of low cost/no cost recreation goes unexplored because of the stigma attached to single parentness. Thus there is a need for recreation professionals to re-look at and re-think how recreational activities are offered through community-based centers and volunteer agencies
