If the OECD??s Development Co-operation Report for 2009 is correct in its claim that ??The international aid effort now adds up to less than the sum of its parts??, then continued rapid growth in aid transfers is likely to contribute to further aid absorption problems, as well as institutional atrophy and deteriorating governance and corruption control among aid recipients. This article considers aid for good governance and anti-corruption, using Tanzania as an example. ??The supply side of aid?? sketches the bigger picture in which such aid is located, stressing collective action problems facing the aid industry in the current period of growth and diversification. ??The consequences of aid proliferation on corruption control in an aid-dependent state?? provides some empirics from Tanzania. ??Conclusions: whither ??corruption control????? draws some conclusions for the future of aid for governance and corruption control. A key message is that donor-driven governance and corruption control initiatives have failed to address the governance weaknesses that excessive and uncoordinated aid has helped to create.  相似文献

The purpose of this paper is to use criminological theories to explain chronic drunk driving. There is little criminological research explaining recidivist drunk driving with criminological theories. Instead, most researchers posit that repeat drunk driving is explained as a byproduct of substance abuse. Although substance abuse is likely correlated to chronic drunk driving, theoretical explanations need to go further to understand a broader set of social and psychological predictors. Factor analysis and linear regression techniques are used to estimate the relationship between items from two assessment instruments with a number of drunken driving offenses. The sample consists of nearly 3,500 individuals on probation and parole in a Southwestern state. The findings support our contention that criminological frameworks are helpful to understand chronic DUI. We found significant results for volatility, antisocial friends, teenage deviance, and negative views of the law, while controlling for age, gender, marital status, and race. DUIs are a serious problem for the criminal justice system and understanding the individual level correlates of repetitive DUI is crucial for policy development. Further, chronic DUI offers criminologists an opportunity to determine the ability of criminological theories to explain this type of behavior.  相似文献

Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures.  相似文献

ABSTRACT

Proving that legislative committees really matter is not simple. The assembled papers aim to demonstrate fruitful paths to analysing when committees influence policy, what they can and should do, and how to detect their importance to the political process.  相似文献

Abstract

This article discusses what it means to “contribute” to waste disposal as that term is used in section 7002 of the Resource Conservation and Recovery Act. More specifically, the article examines whether the US Forest Service can violate section 7002 by not regulating hunting. Among the issues addressed are whether one can contribute to waste disposal passively, whether one can contribute to waste disposal without taking any action that addresses waste disposal and the extent to which the statutory term “contribute” is analogous to the common law concept of causation.  相似文献

ABSTRACT

In local government systems worldwide, financial pressures have obliged local authorities to focus on cost-efficient methods for providing local services, including inter-municipal agreements and public–public partnerships. However, in comparison with municipal mergers, privatisation and other approaches to the problem, the cost impact of the cooperative provision has not yet been thoroughly examined empirically. Moreover, available empirical research has largely concentrated on waste disposal in developed countries. The present paper seeks to contribute to the empirical literature on inter-municipal agreements and public–public partnerships by comparing their impact on costs with ‘stand-alone’ provision in a range of non-waste local services. In contrast to the bulk of existing studies, our analysis takes place in a developing country context by examining Brazilian local government over the period 2013/15. We found that – on the whole – cooperative provision is less expensive than the ‘stand-alone’ provision for the services studied. Our results can be explained by the size and composition of the population, together with the politics for cooperation.  相似文献
