Using new measures to compare both the 48 states and 52 upstate New York counties, this research reformulates V. O. Key's hypothesis that noncompetitive systems benefit upper socioeconomic groups while competitive systems favor the lower classes. In designing these tests, we returned to Key's original conceptualization, which, contrary to the subsequent research that claimed to test his hypothesis, did not separate and oppose the political and economic sectors. In line with Key's formulation, we find that competitive political structure goes hand in hand with competitive economic structure and together they determine an array of fiscal policies that are different from those of noncompetitive political-economic systems. This return to the original sense of the hypothesis resolves many of the puzzling findings that have been generated in the last several decades. Democratic party affiliation and urban differentiation also affected revenues and expenditures. These same characteristics were previously shown to affect poverty and social pathology. That they now affect public policy for dealing with these problems means that those caught in the web of poverty are in double jeopardy. 相似文献

Limit expressions (as the dimension p ← ∞ ) are derived for the relative risk of the James-Stein estimator and its positive-part version. The limit is simple to evaluate, and gives the amount of improvement in risk that is possible. The technique used is to bound the risk, both above and below. with bounds that converge to the same limit. For the James-Stein estimator these bounds are simple to calculate, and are quite accurate even for moderate dimensions. 相似文献

A least-squares analysis of the various estimates of the population of London during the seventeenth century discloses the probable degree of error in the work of William Petty and other early demographers. A new “average” population is calculated and the regression equation given which best satisfies the contemporary estimates. 相似文献

The article discusses misunderstandings and misattunements that occur in the beginning phase of cross-cultural psychotherapy. Sources of micro ruptures are outlined, including client maladaptive patterns, therapist misunderstandings, cross-cultural misunderstandings due to cultural variations, and asymmetrical power relations involving the impact of prior experiences or current therapy practices. Multiple clinical vignettes illustrate the rupture/repair process, drawing on Safran and Muran’s (2000) list of direct and indirect techniques. 相似文献

Data from the Panel Study of Income Dynamics supports predictions from the minority vulnerability thesis concerning the determinants of job layoffs among African Americans and Whites who work in upper-middle-class occupations. Specifically, after controlling for seniority, layoffs for African Americans are relatively unstructured by traditional stratification-based causal factors, namely, background socioeconomic status, human-capital credentials, and job/labor market characteristics. Analyses also indicate that racial differences in the determinants of layoffs are more pronounced in nonservice-based than service-based firms in the private sector and in the private sector relative to the public sector. 相似文献

The purpose of this investigation was to determine whether increases in internal (muscular) demand would be proportional to increases in the external demand during heel-raise exercise. Seven male (mean age 74.9 +/- 4.8 years) and 9 female (mean age 74.4 +/- 5.1 years) older adults performed both double-leg heel raises and single-leg heel raises under 3 loading conditions (no external resistance and +5% and +10% of each participant's body weight). Kinematic and kinetic dependent variables were calculated using standard inverse-dynamics techniques. The results suggest that although the single-heel raise led to increases in peak net joint moments, power, and mechanical-energy expenditure (MEE), it did so at the expense of range of motion and angular velocity. In addition, increasing the external resistance by 5% of participants' body weight did not elicit significant changes in either the power or the MEE of the ankle joint. These effects should be considered when prescribing these exercises to older adults. 相似文献

Wildlife abundance has grown for several species that are adapted to human-dominated landscapes. Overabundant wildlife may
cause nuisance concerns and property damage, or spread zoonotic diseases such as West Nile virus, particularly at the suburban-rural
interface of many communities. Consequently, wildlife damage management has become an important component of the wildlife
profession. The complicated biological and human dimensions of human-wildlife conflicts often require partnerships between
state and federal agencies, universities, local governments, communities, and private wildlife control professionals. The
Northeast Wildlife Damage Management Research and Outreach Cooperative (WDM Coop) was formed to enhance coordination and collaboration
among wildlife agencies, universities, and other cooperators to promote consistent, multi-state approaches for resolving wildlife-related
concerns. During 2001–2004, 12 projects have been funded to examine issues associated with white-tailed deer (Odocoileus virginianus), black bear (Ursus americanus), Canada geese (Branta canadensis), and beaver (Castor canadensis). These projects have focused on a diverse array topics from community-based efforts to control deer populations, to aversive
conditioning techniques for black bears. The Northeast Fish and Wildlife Agency Directors decided to exclude projects focusing
on zoonotic diseases and human health issues from the list of WDM Coop activities. There have been focused efforts concerning
human dimensions inquiry and outreach publications for wildlife management professionals. As state fish and wildlife agency
budgets grow tighter and staff numbers are reduced, we believe more regional centers or wildlife management cooperatives will
be formed to meet the increasing demand for services from multiple states with shared issues and concerns. 相似文献

This paper presents the state of the art for communication of data and information between the various participants in the
port community, as well as between the port administrations themselves. It also presents an innovative application of a port
community communication platform in the Adriatic-Ionian corridor. The system is accessible by both electronic data interchange
and Internet and has been applied on a pilot status in the ports of the Adriatic, Ionian, and part of Northern Aegean Sea
areas. This has been initially developed as part of a number of EU-cofunded projects within the INTERREG/CADSES programme
of DG REGIO (projects TRANSLOGNET, GILDA, GILDA-NET). The system has been designed to improve primarily the efficiency and
safety of intermodal transport and to contribute to the better integration of the Adriatic, Ionian and Aegean Seas into the
European transport networks. 相似文献
