The debate about the use of dedicated trains for shipping spent fuel and high level nuclear waste has been going on for the past 15 years. The nuclear industry and its regulatory agencies would like to consider the case closed. The recent passage of the Hazardous Materials Transportation Uniform Act of 1990, however, opens the door once more, giving the railroads and other proponents of dedicated trains another chance to present their case. This paper argues that earlier conclusions favoring regular trains over dedicated trains were based on incomplete cost and risk information and neglected other factors which are not technical, but social and institutional in nature. The paper finds that the additional cost of a dedicated system is lower than previously thought and concludes that it is a small price to pay for reduced public opposition and increased levels of trust.  相似文献

While radio is America's most abundant medium, its content is characterized more by sameness than by diversity. Stations find it more profitable to duplicate mass appeal programming formats than to program to minority tastes. Such rational business decisions come at the expense of the listening audience which is given few formats from which to choose. The regulatory system, which speaks to the value of program diversity, has been unsuccessful in creating effective incentives to foster radio diversity. The article suggests a novel approach to radio regulation that combines economic incentives with new methods for identifying audience preferences such that a profit-maximizing radio industry would serve more tastes than are presently served.An earlier version of this paper was presented to the Mass Communication and Society Division of the Association for Education in Journalism, Boston, August 1980.  相似文献

The enforcement of the SMCRA in Oklahoma has led to improvements and transformations in the coal industry, state and federal regulatory agencies and the public. The catalyst for these changes was the federal takeover of inspection and enforcement of the SMCRA in Oklahoma with the state carrying on all other mining regulatory activities from 1984 through 1987. This pattern of cohabitation differed from that in Tennessee where OSM took over all enforcement of the SMCRA or that in states that enter into cooperative agreements to provide state regulation of coal mining on federal lands within the state. Cohabitation in Oklahoma produced a new, more positive attitude toward cooperative federalism by both federal and state regulatory bodies that might serve as a model for other states with OSM maintaining state agency support for policy objectives while allowing the state reasonable decisional discretion.  相似文献

Scales for photography provide a geometrical reference in the photographic documentation of a crime scene, pattern, or item of evidence. The ABFO No. 2 Standard Reference Scale (1) is used by the forensic science community as an accurate reference scale. We investigated the overall accuracy of the major centimeter graduations, internal/external diameters of the circles, error in placement of the circle centers, and leg perpendicularity. Four vendors were selected for the scales, and the features were measured on a vision‐based coordinate measurement system. The scales were well within the specified tolerance for the length graduations. After 4 years, the same scales were measured to determine what change could be measured. The scales demonstrated acceptable stability in the scale length and center‐to‐center measurements; however, the perpendicularity exhibited change. The study results indicate that scale quality checks using certified metal rulers are good practice.  相似文献

Elevators are mechanical transportation devices used to move vertically between different levels of a building. When first developed, elevators lacked the safety features. When safety mechanisms were developed, elevators became a common feature of multistory buildings. Despite their well-regarded safety record, elevators are not without the potential for danger of injury or death. Persons at-risk for elevator-related death include maintenance and construction workers, other employees, and those who are prone to risky behavior. Deaths may be related to asphyxia, blunt force, avulsion injuries, and various forms of environmental trauma. In this review, we report on 48 elevator-related deaths that occurred in nine different medicolegal death investigation jurisdictions within the United States over an approximately 30-year period. The data represents a cross-section of the different types of elevator-related deaths that may be encountered. The review also presents an overview of preventive strategies for the purpose of avoiding future elevator-related fatalities.  相似文献
