We have conducted economic simulation, historical, and survey research that considers the national government's obligation to the regions that surround the places where it developed and tested nuclear weapons. The research shows that the strongest case for an obligation is at four site regions: Hanford (Washington), Idaho, Oak Ridge (Tennessee), and Savannah River (Georgia, South Carolina). These four are dependent on the Department of Energy (DOE), have relatively low incomes, are expected to grow less economically than their counterparts and the nation as a whole, and suffer from environmental stigma. We reviewed and simulated the impacts of a variety of tools, including severance packages, onsite projects, and offsite economic investments. In essence, investments in severance packages, education, and recreation are more effective per dollar invested than high technology, but all investments are less effective in these dependent regions than in larger metropolitan areas because of the economic leakage out of these dependent regions. The national government needs to begin a process of working with these regions to help them deal with the shock of shrinking their dependency on the DOE.  相似文献

The UK's honour system is a strange mixture of ancient tradition and Victorian invention, and is drifting into obsolescence. Many of its honours recall a vanished imperial past, or maintain increasingly unacceptable demarcations between classes of recipients. However, the high rate of acceptance of honours and the almost universal existence of similar systems throughout the world suggests that people do still value an honours system. But what form should it take? In 2004 two separate reports looked at most elements of the system and produced recommendations, though their impacts were lost in the shadow of the far more dramatic Butler Report. David Cannadine assesses both honours reports and their prospects for adoption at a time when the policy‐makers and government are preoccupied with other issues. He concludes that the time is right for change — in spite of the inevitable opposition from some quarters — given that both Whitehall and Westminster agree that change is necessary.  相似文献

This study investigates the common-family environmental (CE), within-family environmental (WE), and hereditary (H) components of antisocial behavior and its correlates using a twin study design. The subjects are 265 adolescent twin pairs who reported in a mail survey on their antisocial behavior, deceitfulness, parental rejection (as perceived), anger, impulsivity, and value placed on school achievement. These six variables are intercorrelated in two ways: between-families (twin pairs' sums) and within-families (twin pairs' differences). The former covariance structure captures the twins' resemblances: the latter, the twins' differences in behavior. LISREL is used to model the observed relationships using structural equations containing CE, WE, and H factors. The best-fitting model requires only H and WE factors to explain the variables' relationships. Within this population, delinquent behavior is unaffected by CE influences such as social class, child rearing styles, parental attitudes, parental religion, and other factors equally affecting the twins. The principal genetic correlates of delinquency appear to be deceitfullness and temperamental traits.  相似文献

The effectiveness of regulations is reduced by inspector capture. An environment conducive to capture is one in which inspectors must compete for business. This type of competition is found in various regulatory contexts; it is a fundamental characteristic of a decentralized motor vehicle inspection network.
Motor vehicle inspection stations in most localities are numerous, geographically dispersed, private, and hence largely outside the effective purview of state authorities. Motorists can choose their inspection station, and generally prefer quick, superficial and passing inspections. Motor vehicle inspectors therefore tend to be quite lax. Evidence is presented showing that the most lenient ones tend to get more of the inspection business.  相似文献
