The use of salt for deicing roads results in costs estimated at more than $800 per ton—including the costs of repair and maintenance of roads and bridges, vehicle corrosion costs, and loss of aesthetic value through roadside tree damage. Additionally, there are probable health costs related to elevated sodium levels in drinking water. The new Surface Transportation Act of 1991 appears to replace the previous federal funding policy that was biased against the use of calcium magnesium acetate (CMA) with a new subsidy for its purchase that may lead to inefficient overuse.  相似文献

An examination of self-report scales of 160 men and 76 of their partners or former partners found significant correlations between jealousy and abusiveness (for coupled dyads) or intrusiveness (for separated dyads). Jealousy was related to borderline personality and to MCMI-II measures of Post Traumatic Stress Disorder. Rejection sensitivity leading to pathological acts, such as abusiveness and intrusiveness, is seen as originating in early insecure attachment and exposure to shaming experiences.  相似文献

This report assesses conditions that contribute to or are potentially hospitable to transnational criminal activity and terrorist activity in selected regions of the world during the period 1999–2002. Although the focus of the report is on transnational activity, domestic criminal activity is recognized as a key foundation for transnational crime, especially as the forces of globalization intensify. The report has been arranged geographically into the following major headings: Africa, the former Soviet Union and Eastern Europe, South Asia, Southeast Asia, Western Europe, and the Western Hemisphere. Within the geographical headings, the report addresses individual countries with particularly salient conditions. Cases such as the Triborder Area (TBA) of South America and East and West Africa, where conditions largely overlap national borders, have been treated as regions rather than by imposing an artificial delineation by country. The bibliography has been divided into the same geographical headings as the text. The major sources for this report are recent periodical reports from Western and regional sources, Internet sites offering credible recent information, selected recent monographs, and personal communications with regional experts. Treatment of individual countries varies according to the extent and seriousness of conditions under study. Thus some countries in a region are not discussed, and others are discussed only from the perspective of one or two pertinent activities or conditions. Because they border the United States, Canada and Mexico have received especially extensive treatment.  相似文献
