Governments face a fundamental tradeoff between regulatory independence and control. Attempts of interference have the effect of reducing the system's level of commitment and credibility. On the other hand, an administration runs the risk that the autonomy delegated to regulators might be used to pursue outcomes that may harm their interests. This tradeoff is particularly relevant when there is an alternation of power with the arrival of a new political elite with different preferences. This paper uses data from a 2016 survey on regulatory governance applied to Brazilian regulatory agencies. This data is compared to a similar survey performed in 2005. The new survey results turn out to be surprisingly similar to those of a decade earlier, suggesting strong resilience of regulatory agencies despite significant attempts at political interference by powerful presidents. The factors explaining the resilience of regulatory governance in Brazil lie in its broader institutional endowment, which moderates the effects of executive interference.  相似文献

There is little previous research on firearm background check applications and denials despite the potential for such research to significantly benefit policy and practice. The U.S. firearm background check system is complex with federal, state, and local laws creating a patchwork system intended to increase public safety and reduce mortality. State characteristics may play an important role in changes in application and denial rates. We examined the relationship between application and denial rates and state characteristics such as poverty, race, gender, existing firearm ownership, and population density. Multi‐level longitudinal modeling was used in an ecological study design with the state as the unit of analysis spanning a time period between 2005 and 2010, inclusive. Results indicated that application and denial rates significantly increased over time. Population density and poverty level were negatively related to application and denial rates. Firearm ownership, male population size, and percent of residents that were white were positively related to application and denial rates. Percent of African–American residents was negatively related to application rate. The importance of understanding the factors that predict firearm prevalence and the need for additional research on the denial of firearms is discussed.

ABSTRACT

As government and public administration lag behind the rapid development of AI in their efforts to provide adequate governance, they need respective concepts to keep pace with this dynamic progress. The literature provides few answers to the question of how government and public administration should respond to the great challenges associated with AI and use regulation to prevent harm. This study analyzes AI challenges and former AI regulation approaches. Based on this analysis and regulation theory, an integrated AI governance framework is developed that compiles key aspects of AI governance and provides a guide for the regulatory process of AI and its application. The article concludes with theoretical implications and recommendations for public officers.  相似文献

This article explores the interplay between international donors and local NGOs in Kyrgyzstan's HIV/AIDS sector. It argues that donors have transposed ready-made policies without sufficient consideration of the local context and that NGOs have responded strategically, adapting their proposals and reports to the expectations of donors. This complex interplay has resulted in unintended consequences that have undermined an effective response to the HIV/AIDS epidemic. It has given rise to ‘virtual realities’ detached from developments on the ground. The funding system has also led to corruption and misappropriation of funds and the failure of NGOs to become sustainable. Largely bypassing the state in the allocation of funds, international donors have also undermined an already weak state.  相似文献

This report describes certain interesting postmortem findings in the hearts of five subjects who died suddenly, silently, and unexpectedly, and in whom the only significant abnormality at autopsy was asymmetric septal hypertrophy (ASH) of the heart. Deep clefts, cystic faults, and dilated vascular channels were not only seen within the septal myocardium in all the hearts, but also within the left ventricular free walls of two hearts. The septal myocardium and the left ventricular free walls of two hearts and the A-V node and His bundle of one heart demonstrated mural and luminal thrombi of several dilated vascular channels. In another heart, foci of cardiocytic myofibrillar degeneration were seen, especially close to narrowed small coronary vessels. Fetal dispersion and fibrosis of the A-V node and His bundle were evident in one heart. These abnormalities in the conducting system and the ventricular myocardium suggest that the hearts of subjects with ASH are not only excellent anatomic substrates for lethal arrhythmias, but also are bound to be hemodynamically impaired. We believe that conditions such as hypoxia, increased oxygen demand by the heart or abnormal sympathetic stimulus may easily trigger fatal arrhythmias in such individuals, thereby causing sudden death.  相似文献

Abstract: Certain aspects of the new Australian tax sharing arrangements are analysed against the background of West German experiences. Emphasis is laid on Federal-State relations in outlining the basic characteristics of the German machinery and the Australian arrangements. Compared to the Australian situation, the tax sharing base in West Germany is much broader and has indeed contributed to the safeguarding of State autonomy to a large extent. On the other hand, the German States have no individual power to legislate on taxes or tax surcharges. Although tax sharing is a powerful instrument in mitigating financial imbalances in a federation, it tends to conflict with the idea of a centrally controlled stabilization and distribution policy. In Germany, tax sharing is complemented by a complex coordination machinery stabilizing joint decision making of the Federal government and the States. In areas such as demand management, financial planning and allocation policies there seems to be need for such complementary arrangements, since tax sharing alone cannot achieve sufficient coordination among the different administrative levels of a federation.  相似文献

This article is an examination of failures in implementing intergovernmental programs. The programs were failures in the sense that actions to implement programs were delayed far beyond the expected dates of completion. Two such failures in cities implementing two different programs (wastewater management and Section 8 housing programs) are contrasted with one instance of success (in Section 8 housing). If a Sharkansky's discussion of political and policy routines is found to be a useful explanation of the different results. When local government routines must be broken to comply with the goals and objectives of federal programs, local actors will do all they can to resist the federal program. This finding demonstrates the importance of varying local political environments in explaining varying patterns of implementation of federal programs.  相似文献

Banknote evidence is often submitted after a suspect has attempted to disguise or remove red dye stain that has been released because of an anti-theft device that activates after banknotes have been unlawfully removed from bank premises. Three chlorinated compounds have been synthesized as forensic chemical standards to indicate bank security dye bleaching as a suspect's intentional method for masking a robbery involving dye pack release on banknotes. A novel, facile synthetic method to provide three chlorinated derivatives of 1-(methylamino)anthraquinone (MAAQ) is presented. The synthetic route involved Ultra Clorox bleach as the chlorine source, iron chloride as the catalyst, and MAAQ as the starting material and resulted in a three-component product mixture. Two mono-chlorinated isomers (2-chloro-1-(methylamino)anthraquinone and 4-chloro-1-(methylamino)anthraquinone) and one di-chlorinated compound (2,4-dichloro-1-(methylamino)anthraquinone) of the MAAQ parent molecule were detected by gas chromatography mass spectrometry (GC-MS), and subsequently isolated by liquid chromatography (LC) with postcolumn fraction collection. Although GC-MS is sensitive enough to detect all of the chlorinated products, it is not definitive enough to identify the structural isomers. Liquid-state nuclear magnetic resonance (NMR) spectroscopy was utilized to elucidate structurally the ortho- and para-mono-chlorinated isomers once enough material was properly isolated. A reaction mechanism involving iron is proposed to explain the presence of chlorinated MAAQ species on stolen banknotes after attempted bleaching.  相似文献
