This article uses the New Beneficiary Data System to describe the first job held after award of Disability Insurance benefits, in terms of occupation and industry. It examines work activity within sectors of employment, and looks at the issues of whether work return in certain industries and occupations varies according to the demographic characteristics of the beneficiaries. The article also presents data on sector-specific employer accommodations that can aid in sustained work return. Postentitlement work was fairly evenly distributed across occupational and industrial sectors. Persons with higher levels of educational attainment were found to be in white-collar employment sectors. There were noticeable differences in the availability of employer accommodations across postentitlement occupations and industries. 相似文献

Policy implications of climate forecasts for water resources management in the Pacific Northwest 总被引:1,自引:0,他引:1
The Columbia River Basin management system suffers from conflicts over water use and allocation, and vulnerability to climate variability that disrupt hydropower, fisheries, irrigation, water supply, and other vital activities. Climate forecasts have the potential to improve water resource management in this system supporting management decisions that decrease its vulnerability to droughts, floods, and other crises related to climate variability. This study shows that despite the potential utility, managers do not use climate forecasts except for background information. The barriers to managers' use of climate forecasts include low forecast skill, lack of interpretation and demonstrated applications, low geographic resolution, inadequate links to climate variability related impacts, and institutional aversion to incorporating new tools into decision making. To realize the potential of climate forecasts for water resources management, we recommend strategies that include technical improvements to the forecast products, and joint efforts between forecast producers and the management community to develop and demonstrate climate forecast applications through reciprocal and iterative education. 相似文献

"This article compares two sources of data on Mexico-U.S. migration, based on radically different methodologies: the Mexican Migration Project (Promig) and the National Survey of Population Dynamics (Enadid).... This comparative study shows that a micro-social design drawing on multiple community samples, such as Promig, can solve the methodological conflict between specificity and representativeness.... The authors' research also highlights the problem of selectivity and specificity entailed by traditional surveys such as Enadid as a result of restricting their samples to international residents in Mexico and attempting to explain such a complex, socioeconomic process using a limited number of variables."

The State of Texas's local government investment pool, TexPool, has faced major challenges in the 1990s. This article provides an overview of two major events involving TexPool: (1) a $2.2 billion "run" on the pool in 1994 and (2) the out-sourcing of TexPool's functions in 1997. The article describes these events and analyzes potential implications for other state-administered investment pools. The article addresses issues such as: (1) the need to develop investment policies and practices that are suitable for a particular pool's objectives and purpose, (2) whether a state government has a responsibility to ensure that participants in a state investment pool do not incur losses, (3) the possible implications of having an elected official as the person with primary responsibility for overseeing the pool, and (4) concerns related to the outsourcing of state investment pools. This article is intended to encourage debate on the policies and practices of state investment pools, which currently are serving more than 15,000 local governments in the United States. 相似文献

This article examines option hedging strategies that enable politicians to manage budgetary risk. While the theoretical risk management arguments are general, the simulation analysis considers the example of oil revenue risk in Texas, and estimates the costs and benefits of an option hedging program. To evaluate government option hedging strategies, the study develops a hedge quotient measure that compares the future value of realized revenues plus net option proceeds to the future value of expected revenue. The average hedge quotient is found to be lower for the option hedging strategy than for the unhedged position, illustrating the cost of an option hedging program. Nevertheless, option hedging effectively manages extreme downside risk and stops large budget deficits from occurring. Politicians may also like option hedging because it preserves the potential of realizing budget surpluses. 相似文献

Public choice theory has emphasized economic explanations of privatization decisions, while often neglecting the politics associated with the decision-making process. This research finds that the political context is important in understanding why American municipal governments decide whether or not to privatize a service. Four case studies reveal that the degree to which the decision-making process is politicized is a factor warranting our attention. 相似文献

It is well known that rural communities do not have access to the same range of healthcare services as urban communities and that health status is poorer in rural areas. As models of health service delivery are changing from treatment and illness prevention to wellness models, health providers are under increasing pressure to re-engineer healthcare services to rural and remote areas in a climate of shrinking resources and community skepticism. The purpose of this article is to examine a developing model of partnership in rural Tasmaniain the context of these changes to health service delivery, changes to health professional training and the application of information and telecommunications technology. The partners are the Tasmanian Department of Health and Human Services and the University of Tasmania. The establishment of the university's Rural Health Teaching Sites in conjunction with the Tasmanian Telehealth Network provides a demonstration of this partnership in action. 相似文献

The history of poverty lines suggests that they are determined jointly with poverty policy in the same political game. If the definition of poverty is endogenous, however, why do altruistic voters allow poverty to persist indefinitely, as seems to be the case in real life? A simple redistribution model shows that the persistence of poverty imposes fairly strong restrictions on the nature of voter altruism. Specifically, a voter's compassion for the poor must rise as the defined severity of the poverty problem worsens. Given such preferences, political actors face incentives to define poverty as a severe problem and then to use redistribution to reduce it significantly. There is no direct incentive to eliminate poverty, however; indeed, voters may prefer a state in which policy always attacks poverty vigorously and yet never defeats it. It follows that social policy should not be judged by its success in eliminating poverty, which may be directly counter to voter interests and therefore practically impossible. Rather, we should ask whether poverty policy provides enough help to people whom voters currently consider to be poor. 相似文献
