Philip G. Joyce 《Public Budgeting & Finance》2005,25(1):15-31
Federal budgeting has undergone some profound changes since the tragic events of September 11th, 2001. Large surpluses that existed prior to September 11th and were forecast to continue have been replaced by equally large and intractable deficits. The consensus around a macro‐level norm for federal budgeting has completely broken down. In other ways, the federal budget process has not changed at all. Despite the emphasis on defense and homeland security, domestic discretionary spending is still continuing unabated, as it has since the late 1980s. Further, the federal government continues to have chronic difficulty adopting its budget in a timely fashion. 相似文献

The authors utilize the two latest ICMA Profile of Local Government Service Delivery Choices surveys to investigate whether the service provision and delivery arrangement information reported in the surveys accurately represents reality and, if not, what factors contribute to generating incorrect or unreliable survey responses. Interviews with practitioners are used to better understand both the accuracy of the survey responses and improvements that could be made to the survey instrument. Results suggest that the ICMA ASD survey data are highly erratic, with more than 70 percent of the cases (N = 70) investigated containing some inaccuracies. A qualitative analysis shows that the majority of the errors appear to be caused by the lack of a clear definition of service provision or by the service titles being too vague or too broad, both of which likely lead to discretion in interpreting survey questions and thus inconsistent answers by individual respondents over time. 相似文献

In a companion paper to “Environmentalism in the USSR: The Opposition to the River Diversion Projects,” two geographers survey the current status of water transfer research after cancellation of the European and Siberian diversion projects and offer a different perspective on the debates leading to that cancellation. Implications of a demand-side approach to Centra! Asian water management problems are then assessed in light of (a) contradictory objectives of expanding irrigated hectarage and mitigating environmental deterioration in the Aral basin and (b) the problematic nature of projected water savings and costs involved in their realization.

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献
