Estimating postmortem interval (PMI) of surface found skeletal remains is challenging. This novel study used UV‐Vis‐NIR spectroscopy to scan soil collected from cadaver decomposition islands (CDIs) ranging from 15‐ to 963‐d postmortem and control soils. A decomposition product spectra model (DPS model) was constructed by deducting the control soil spectra from the CDI soil spectra for the estimation of postmortem indices: PMI (d), ADD4, ADD10, and ADD20. The DPS model (n = 55) was calibrated and subjected to a full cross‐validation. Calibration R2 and RPD for the DPS model ranged from 0.97 to 0.99 and from 6.1 to 9.9, respectively, for the four postmortem interval indices. Validation R2 and RPD for the DPS model ranged from 0.73 to 0.80 and from 1.9 to 2.2, respectively. The DPS model estimated postmortem intervals for three test CDIs in a clay soil under perennial grassland (test set 1; n = 3) and six CDIs in a sandy soil under a loblolly pine forest (test set 2; n = 6). Test set 1 had PMI prediction ranges from ?69 to ?117 days, ?796 to +832 ADD4, +552 to +2672 ADD10, and ?478 to ?20 ADD20 of observed PMI. Test set 2 PMI prediction ranged from ?198 to ?65 days, ?9923 to +2629 ADD4, ?6724 to +1321 ADD10, and ?2850 to +540 ADD20 of observed PMI. Test set 2 had poor predictions for two CDIs, for all measures of postmortem indices resulting in discussion of sampling depth, effect of body mass index (BMI), and scavenging. 相似文献

Abstract Our paper shows that the deficient educational system and the large share of unskilled foreign workers in the Gulf countries are serious impediments to a successful implementation of the strategies of these countries to reduce their dependence on foreign technologies and to restructure their economies in order to make them less dependent on oil exports. A novel element in our analysis is that we emphasise the role of the deficient educational system as an important problem, next to the well-documented quandary of a high incidence of unskilled foreign workers in the workforce. We use new survey data, both at an establishment level and economy-wide, to provide evidence on how the poor educational facilities lead to a poor provision of training, low skill levels, serious skills mismatch and deficient transfer of knowledge. These inadequate facilities and the lack of incentives to improve them also lead to low R&D efforts to promote local technologies and hamper a restructuring of the economy. 相似文献

Much of the privatization that is occurring in Latin America is leading to improved efficiency. However, privatization in areas where markets do not yield efficient solutions, for example of public goods, like light houses, natural monopolies, mainly utilities, and goods with externalities, like education, can lead to lower output and higher costs in the long run. This paper first presents an outline of the shift in development theory with respect to the role of the public sector. It then examines the growth of Ecuador's public sector and its current debate on how privatization should proceed. It concludes that while careful privatization can be positive, privatizing natural monopolies like the electric utility and/or quasi-public goods, like highways are likely to be detrimental to long run economic development. In order for Ecuador's economy to continue to develop, the public sector still needs to play a significant role in developing human capital and physical infrastructure. 相似文献

ABSTRACTIntellectual property is a legal concept used to regulate cultural goods and artistic forms of expression. It constitutes a peculiar regulation, as it applies the categories of private property to intangible goods. With the spread of Information and Communications Technology (ICT), which has allowed for the reproduction and global diffusion of these cultural goods, conflicts concerning intellectual property have increased. This article attempts to analyze some difficulties in using a concept such as private property to approach the marketing of cultural goods, especially when technology eliminates the quality of scarcity of these goods, which can be infinitely reproduced at almost zero cost. 相似文献

We use data from an innovative nationally representative survey of 6,000 Pakistanis in April 2009 to study beliefs about political Islam, Sharia, the legitimacy and efficacy of jihad, and attitudes towards specific militant organizations. These issues are at the forefront of U.S. policy towards Pakistan. Four results shed new light on the politics of militancy and Islamic identity in Pakistan. First, there is no relationship between measures of personal religiosity and the likelihood a respondent expresses highly sectarian sentiments. Second, militarized jihad is widely seen as legitimate in Pakistan but there are substantial regional differences in the acceptance of militarized jihad. Third, attitudes towards militant groups vary dramatically across groups, particularly when it comes to the efficacy of their actions. Fourth, while Pakistanis express massive levels of support for Sharia law, this is driven by its perceived connection with good governance, not by sympathy with the goals of militant groups claiming to implement it. 相似文献

Regulating Law Firms from the Inside: The Role of Compliance Officers for Legal Practice in England and Wales

Following the Legal Services Act 2007, which permitted the delivery of legal services through Alternative Business Structures (ABS), the Solicitors Regulation Authority required all regulated legal service firms to appoint Compliance Officers for Legal Practice (COLPs). COLPs are charged with taking reasonable steps to ensure that firms comply with their obligations, which entails interpreting what outcomes‐focused regulation (OFR) requires of the firm. Yet despite their importance, little is known about how compliance roles operate within legal service firms. We addressed this gap through a series of qualitative interviews that explored COLPs’ views of their roles, their attitudes to regulation, in particular to OFR, and to achieving compliance. We found that COLPs are a key regulatory mechanism in the context of firm‐based regulation and OFR and have a critical role to play in protecting and promoting professional values in both ABS and non‐ABS entities. 相似文献

This note amends the model of informational lobbying presented in Potters and van Winden (Public Choice 74:269–292, 1992). In the original article, the authors find that only separating and pooling equilibria exist when the cost of lobbying is intermediate and the policymaker’s prior favors the interest group’s preferred policy. However, we prove that a semi-separating equilibrium also exists under these conditions. Implications for lobbying behavior are discussed. 相似文献

This paper examines the growth of transnational networks of innovation and proposes a preliminary classificatory system of four distinct kinds of forces which give rise to social networks that facilitate knowledge flows, relationship building, and collaborative activities important to accessing global markets. The networks may form around a technology sector, be identity based, emerge from a government-led initiative, or be stimulated by a civic or philanthropic organization. Each has a different mode of organizing, financing, and meeting its objectives, as shown by examples presented in the paper. The proposed classification of these characteristics is intended to open a conversation within the social sciences and among policy makers about how better to understand the ways in which transnational networks get formed, operate and produce desired results. 相似文献
