Fourier-transform infrared spectroscopy (FTIR), discriminate analysis, X-ray fluorescence spectrometry (XRF), and stereoscopic microscopy were used to separate black coral forensic evidence items from similarly appearing items manufactured from plastics, bovid keratin, and mangrove wood. In addition, novel observations were made of bromine and iodine relationships in black coral that have not been previously reported. 相似文献

This article develops the concepts of regulatory legal strategy, a resource-based view of government agencies, and regulatory entrepreneurship. These ideas are explored through a case study of the limited (if any) access that legal cannabis-related businesses have to the banking system due to the clash between federal law and laws in those states that have legalized some uses of cannabis. This article argues that regulators’ entrepreneurial regulatory legal strategies can have a material impact on regulated entities and give them a competitive advantage. To demonstrate, this article claims that regulators’ adoption of permissive regulatory legal strategies has facilitated access of some cannabis-related businesses to the banking system. Conversely, if regulators adopted obstructive regulatory strategies, this would act as a constraint on such access in the future, even if Congress resolves the federalism issue largely responsible for the current limitations these businesses face. 相似文献

Leaking underground storage tanks (USTs) are a pervasive national environmental problem. Cleanup of leaking USTs is largely publicly financed and under the control of state agencies. In the transition to new compliance standards, individual states have taken advantage of provisions in federal regulations to implement their own programs. This raises the policy question of environmental federalism and the appropriate locus of government control. The objectives of this study are to examine the revealed preferences of a state UST bureau. New Mexico was one of the first state programs to use risk assessments in setting funding priorities. We analyze the statistical determinants of funding decisions and find strong evidence that risk information is used. Although our case study provides a measure of support for state control, the argument is strengthened if public financing is limited to the cleanup of historical pollution, rather than a means for providing insurance for prospective pollution. ©1999 by the Association for Public Policy Analysis and Management. 相似文献

In the 2007–08 financial crisis, over‐the‐counter (OTC) derivatives triggered the collapse of colossal financial institutions. In response, global policy makers instituted clearinghouse mandates. As a result, all standardized OTC derivatives must now use clearinghouses, and global financial market stability now depends upon these institutions. Yet certain underlying legal and regulatory structures threaten to undermine clearinghouse stability, particularly were a significant clearinghouse to become distressed. This article argues that the clearinghouse mandates are incomplete in that they fail to reform these problematic arrangements. As with electric utilities, the lights at the financial market infrastructures known as clearinghouses must always be on. Yet the legal frameworks for handling a distressed clearinghouse, the problem of clearinghouse recovery, and resolution, remain uncertain. This article advances debate on this issue. It argues that recovery, a private market restructuring process, can be conceptualized as a bargaining game dependent upon time‐critical cooperation between a clearinghouse and members. This article uses transaction cost economics to demonstrate, however, that certain underlying legal and regulatory structures could work at cross‐purposes to this necessary cooperation, and actually increase its cost. Based upon this analysis, it proposes reforms designed to ensure that parties’ incentives promote efficient recovery. In the absence of efficient recovery frameworks, the path of a distressed, significant clearinghouse is likely to resemble that of the government‐backed mortgage lenders whose fate more than ten years after their entry into conservatorship remains uncertain. This article aims to help avoid a repeat of this history. 相似文献

Respiratory pathogens have been detected in forensic investigations using multiple techniques; however, no study has examined the use of automated, nested, multiplex polymerase chain reaction (ANM‐PCR), commonly used in living patients, in the forensic setting. This retrospective study assessed the utility of ANM‐PCR in detecting respiratory pathogens in the pediatric forensic setting. Respiratory samples from 35 cases were tested for up to 20 respiratory pathogens. 51.4% of these cases yielded a positive ANM‐PCR result, 20% of which were considered the cause of or contributory to death. The most commonly detected pathogens were rhinovirus/enterovirus and respiratory syncytial virus, and these were the only pathogens determined to play a significant role in cause of death. The sampled sites and postmortem intervals tested did not affect the likelihood of a positive or negative test. ANM‐PCR panels are effective, affordable, and rapid ancillary tools in evaluating cause of death in the forensic pediatric population. 相似文献
