The study, using the recent contrasting experience of budget reform in Malaysia and Australia, inquires why quite similar changes were attempted in different socio-economic and fiscal settings. It explains why their implementation differed and identifies the factors that shaped, sustained, or impeded the respective efforts.
Three basic themes emerge. First, political and administrative will are necessary requirements for the success of any budget reform effort. Second, the more correspondent the bureaucratic culture is with the culture upon which the new budget system is premised, the more easily change occurs. Third, a model of reform predicated upon the assumption of fiscal restraint cannot effectively function in a climate of fiscal relaxation. Malaysia adapted its budget model from the Australian system. As the Australian model suited the paradigm of expenditure restraint, the adapted model proved less workable against the Malaysian climate of fiscal relaxation.  相似文献

South Florida is experiencing an affordable rental crisis that is especially burdensome on those most vulnerable in society, low-income households. Rapid urbanization has resulted in inequitable land-use patterns that are a barrier to housing for the poor. As a solution to the crisis, local housing agencies seek to expand their affordable housing stock for vulnerable renters in opportunity-rich neighborhoods, but there is no standard framework for identifying properties for acquisition. Broward County serves as a case study to develop a housing acquisition tool. Using a combination of spatial statistics and principal components analysis, neighborhoods in which housing agencies may consider acquiring property are identified through the creation of an affordability surface in ArcGIS. Affordability is overlain by an opportunity surface derived from neighborhood quality and accessibility rankings. The results identify neighborhoods in Broward County that are both affordable and opportunity-rich, to better serve the county's most vulnerable renters.  相似文献

Elemental analysis of calcium (Ca) and phosphorus (P) has been shown to be useful in differentiating skeletal and nonskeletal material. X‐ray fluorescence spectrometry (XRF) is an attractive, nondestructive technique for forensic anthropologists, and the development of portable XRF instrumentation is promising for field applications. This study examines the performance of handheld XRF instrumentation operated in air compared to a traditional benchtop XRF device that has the ability to control the analysis atmosphere. Both instruments can be used to effectively distinguish skeletal from nonskeletal remains. However, as the measurement atmosphere affects detection levels for calcium and phosphorus, Ca/P ratios obtained from the instruments and analysis conditions were found to differ significantly, with analyses conducted in air showing significantly lower phosphorus detection. Consequently, comparison of Ca/P ratios to conclude skeletal versus nonskeletal origin must be based on data collected under similar analysis conditions.  相似文献

As first responders who are frequently exposed to job-related trauma, police officers are at an elevated risk of adverse mental and physical health outcomes. Evidence-based approaches to stress reduction are sorely needed to address the complex variety of problems that police officers face. In this pilot study we examined the feasibility and preliminary effectiveness of a mindfulness-based intervention designed to address police officer stress. A total of 43 police officers completed an 8-week Mindfulness-Based Resilience Training (MBRT) program, which was designed to improve mindfulness, resilience, stress, health outcomes, and emotional functioning. Using multilevel models we found significant improvement in self-reported mindfulness, resilience, police and perceived stress, burnout, emotional intelligence, difficulties with emotion regulation, mental health, physical health, anger, fatigue, and sleep disturbance. Although there were no significant pre-to-post-MBRT changes in cortisol awakening response (CAR), while controlling for pre-MBRT increase area under the curve (AUCI), change in mental health was a significant predictor of post-AUCI. Implications of these findings and areas for future research are discussed.  相似文献

This article discusses how parties who are negotiating administrative agreements with regulatory agencies regarding the remediation of inactive hazardous waste sites can best protect their right to bring a contribution action against other responsible parties. The article discusses the relevant statutory provisions and the case law, much of which holds that parties failed to preserve their contribution rights, and provides advice regarding specific language to include in such agreements.  相似文献

Over the last two decades a large and important literature has emerged that uses game theoretic models of bargaining to study legislative coalitions. To test key predictions of these models, we examine the composition of coalition governments from 1946 and 2001. These predictions are almost always expressed in terms of parties' minimal-integer voting weights. We calculate such weights for all parliamentary parties. In addition, we develop a statistical model that nests the predictions of many of these models of the distribution of posts. We find that for parties that join (but did not form) the government, there is a linear relationship between their share of the voting weight in parliament and their share of cabinet posts. The party that forms the government (the formateur) receives a substantial "bonus" relative to its voting weight. The latter finding is more consistent with proposal-based bargaining models of coalition formation and suggests that parties gain disproportionate power not because of their size but because of their proposal power.  相似文献

Mammalian whole blood sources are often used for forensic research and training when human samples cannot be sourced. While porcine, ovine and equine blood have been shown to be viable alternatives to whole human blood for forensic purposes, procurement can still pose a problem, especially for smaller and remote institutions. This work explores the use of whole bovine blood for basic bloodstain simulation. Sample preparation through the addition of ACD-A anticoagulant was optimized and storability was explored. Viscosity, surface tension, density, and packed cell volume, four fluid properties relevant to bloodstain pattern analysis, were monitored over four days and in two temperature conditions. Linear mixed models accounting for variation in the donor demonstrated that these fluid properties of the bovine blood changed predictably over time and with temperature. Whole bovine blood with 12.5% v/v ACD-A was found to be viable for use in basic bloodstain simulation at ambient and physiological temperature.  相似文献
