Public managers must often cope with competing and conflicting goals. The common formulation is to assume that managers must trade‐off goals against each other. But is this always true? An alternative hypothesis is that sometimes managers may instead be able to improve outcomes on multiple goals simultaneously—by altering management practices. We test this “trade‐off” notion using a panel of state‐level administrative data from the U.S. unemployment insurance (UI) system from 1997 to 2004 and qualitative interviews from selected states. The trade‐off examined is timeliness of UI benefit payments versus the quality of UI determinations. In general, we find that state administrators often adopt management practices that facilitate improved outcomes for both timeliness and quality, indicating no trade‐off but instead a synergy between outcomes. We also find evidence of a feedback effect linking higher performance on timeliness to better quality determinations.  相似文献

‘Command and control’ has become ever more important in the postmodern military world even though there is no universal consensus among contemporary militaries on what ‘command and control’ encompasses. Military histories, manuals and handbooks of the Anglo-American world concede that classical armies and leaders understood the concepts but dismiss eras like the long twelfth century entirely or present them with a lack of understanding or context. Why is this? This can be partially answered through the following factors: (1) the nature of ancient vs. medieval source material; (2) perceived lack of professionalism in medieval armies; (3) the existence of discrete tactical formations in the ancient world but not medieval; (4) the perceived existence of a professional officer class or political career in the ancient world but not the medieval; and (5) the nature of ancient and medieval authority and strategic, operational and tactical objectives. Twelfth-century commanders exhibited command and control although they faced different challenges compared to their ancient or modern counterparts.  相似文献

A Red deer, Cervus elaphus L., skeleton from Seamer Carrs was excavated and the collagen fraction of one of the bones dated to 4330 ± 100 bp (Birm. 977). The bones were embedded in a limnic sediment that was dated to 7360 ± 120bp(Birm.882). This date was confirmed by the pollen assemblage, which indicated a Flandrian I/II chronozone age. The date of the Cervus bone is explained by its movement vertically downwards in the limnic sediment. Attention is drawn to the number of large mammalian skeletons that have been recovered from Seamer Carrs during drainage operations and subsequently, and to the mesolithic and neolithic artifacts recovered from the slopes around the Carrs.  相似文献

A tension exists between government and the academy. State and federal agencies demand that colleges and universities demonstrate their accountability for public funds and to public policy initiatives. The campuses hold that such requirements have come to represent an inappropriate intrusion into institutional affairs and that they present a serious challenge to academic freedom. While a reduction and redirection of regulation may serve the colleges veil, a review of history indicates that the important developments in higher education have occurred during periods of government involvement. Perhaps, then, the real fear that should be felt on campus is the- recent trend of government disinterest in higher education.  相似文献

The toxic waste dispute that is the subject of this article points out one of the troubling ironies of the modem environmental movement. Many groups and individual activists who promoted a national response to the discovery of thousands of toxic waste sites over a decade ago are now leading the struggle to prevent government-sponsored cleanups. This case study examines the evolution and dynamics of one community's pollution controversy, and then attempts to explain the way in which marginalized environmentalists were able to redefine the toxics debate. Finally, it shows how heal resistence to waste cleanups may shape the next round of environmental policymaking.  相似文献

ABSTRACT.  This article implements a spatially explicit model to estimate the probability of forest and agricultural fires in the Brazilian Amazon. We innovate by using variables that reflect farm-gate prices of beef and soy, and also provide a conceptual model of field management and deforestation fires to simulate the impact of road-paving, cattle exports, and conservation area designation on the occurrence of fire. Our analysis shows that fire is positively correlated with the price of beef and soy, and that the creation of new conservation units may offset the negative environmental impacts caused by the increasing number of fire events associated with early stages of frontier development.  相似文献

A helium-enabled Niton X-ray analyser (HHpXRF) study of 296 lava stepping stones from ancient Pompeii showed that their surfaces were contaminated with superficial deposits of Zn and Pb. Recent research has shown that concentrations of these elements are highest in urban areas, where they were attributed to tyre dust and leaded petrol, respectively. The distribution of these elements on the stepping stones is represented on maps of the site. Zn pollution is most abundant in areas visited by tourists and is attributed mostly to wear from their rubber-soled footwear. Pb pollution is attributed to the movement of onsite vehicles using leaded petrol.  相似文献
