Tetramethylene disulfotetramine (tetramine) is a rodenticide that has been banned for many years in China. Since 2005, inhabitants of a village in the Henan Province have been suffering from grand mal seizures. To investigate the possibility of tetramine as the cause, we developed a method to determine tetramine in human hair. Sample preparation involved external decontamination, frozen pulverization, and ultrasonication in 2 mL ethyl acetate in the presence of cocaine-d3 as an internal standard. The method exhibited good linearity; calibration curve was linear over a range of 0.1-20 ng/mg hair. The limit of detection for the assay was 0.05 ng/mg hair. Except for one subject (No. 4), all head and pubic hair samples were positive for tetramine. The concentrations of tetramine in pubic hair were significantly higher than those in the same subjects' head hair samples. Because of a long retention in body, segmental head hair analysis cannot provide an accurate exposure history of tetramine in the body.  相似文献

This article focuses on two groups of Southern Cone exiles' communities, Chileans and Argentineans, choosing to settle down in an atypical destination: the United States. After estimating some qualitative and quantitative findings, the article delves into the ways these communities settle down, remember their relationship with politics, maintain their connection with exiled fellow‐countrymen worldwide and perceive their national identity. By relying on an empirical, single‐case perspective, with no theoretical ambitions to extrapolate its conclusions to other contexts, this article examines the extent to which the conceptualisation of the exile and diaspora categories changes when applied to these two communities.  相似文献

Abstract: This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the “injuries,” using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer‐aided programs in this study of bite marks.  相似文献

Normative deliberative theory has contributed much to an understanding of ideal procedural standards, but there is considerable uncertainty regarding the appropriate nature of desired deliberative outcomes. In this paper we identify two inter‐related concepts of meta‐consensus and inter‐subjective rationality as outcomes that an authentic deliberative process ought to produce. Importantly, these deliberative ends are consistent with ideal deliberative procedure. They are also empirically tractable, where preference transformation can be described in terms of underlying values, and judgments. Methods for assessing deliberative ends are provided and demonstrated using a case study.  相似文献

Two challenges stand out in the study of deliberation: the development of appropriate methodological tools and the development of more unified analytical frameworks. On the one hand, analysing deliberative processes is demanding and time‐consuming; hence we tend to have only few and non‐randomly selected cases at the group or context level. In addition, the real world of deliberation presents us with a complex matrix of nested, cross‐classified, and repeated speakers. This article shows that Bayesian multi‐level modelling provides an elegant way to tackle these methodological problems. On the other hand, we attempt to enrich comparative institutionalism with individual characteristics and psychologically relevant variables (such as group composition). Focusing on Swiss and German parliamentary debates we show that institutional factors ‐ in particular, consensus systems ‐, the gender composition of committees and plenary sessions, and age matter for the quality of deliberation. Furthermore, we also show that partisan affiliation ‐ government or opposition status of MPs ‐ affects deliberative quality and can refine institutional arguments. We conclude that a multi‐level approach to deliberation focusing on contextual and actor‐related characteristics and using Bayesian hierarchical modelling paves the way toward a more advanced understanding ‐ and methodological handling ‐ of deliberative processes.  相似文献

New technologies provide new channels of access to political information and participation in decision‐making processes. This assumption is clearly important in the action plans and policies of International Organizations (World Bank, Organisation for Economic Co‐operation and Development, United Nations), which have assumed a leadership role in the reform of political institutions. Starting from an analysis of the reasons that have brought the state and processes of institution building back into focus, this paper will reconstruct the International Organizations' vision of the transformative potential of new information technologies and their activity in this field. Particular attention will be devoted to e‐democracy and e‐government as policies to build democracy in developing countries.  相似文献

Scholars often attribute deterioration in common‐pool resources (CPRs) to ill‐defined property rights and suggest privatization and tradable permit markets as a solution to the commons problem. CPRs are heterogeneous, differing in physical characteristics and use patterns. Regulating their use requires tailored policy solutions that cohere with these characteristics. This paper examines factors that contribute to a well‐performing tradable permit market. While the literature offers rich empirical analyses of individual tradable permit markets, it has not provided an analytical framework enabling comparative analysis of these markets. This paper develops and employs an analytical framework for comparing across markets. The comparative analysis of market performance suggests that markets are not successful in all environmental problems and all demand situations. Further, it shows that even some markets frequently cited as exemplary successes have been that for nonmarket‐related reasons. On the other hand, this comparative analysis identifies sources of success for markets that partial analytical frameworks would have predicted to fail.  相似文献

We know relatively little about the economic effects of “insignificant” rules because they are not typically analyzed. Yet, these rules could be cumulatively important. We provide an economic analysis of one proposed rule to control hazardous air pollutants, which is not considered to be economically significant. This rule is of particular interest because it is one of the first in a long series of rules that Environmental Protection Agency (EPA) will consider for limiting hazardous air pollutant emissions. Our analysis suggests that the proposed controls that EPA has considered are not likely to pass a benefit–cost test. We recommend that an agency base its decision to allocate additional resources to benefit–cost analysis on the expected value of the improved information. In addition, agencies should consider applying a rule of thumb that would specify a threshold level of risk reduction that needs to be achieved before some kinds of regulation are considered.  相似文献

Despite widespread adoption of Porter's Industrial Cluster Theory as a policy development framework by federal and state governments over the past decade, Australia remains significantly below the OECD average in terms of its industries' economic contributions to real wealth creation ( Brown 2000 ; OECD 1998 ). The major cause cited for this relatively poor performance has been inability of key government officials to implement effective industry policy that simultaneously avoids de facto protectionism and distortion of competition. This article provides an insight into the key policy decisions undertaken by the Tasmanian state government that coincided with development of an internationally successful shipbuilding industry in that state. As such, this article provides a reflection on policy initiatives that may be valuable for government officials elsewhere.  相似文献

This article presents a conceptual framework for analysing the governance of natural resource use, as governance is often the primary issue when natural resources are overexploited and degraded. It addresses both spontaneous and active governance, including institutional change induced by development co‐operation. Drawing on existing frameworks of institutional analysis, fundamental modifications are presented to adapt the concept to the context of international co‐operation, and to include dynamic aspects of institutional change as well as multiple actor interactions. Tested in several case studies, the framework was found suitable and relevant for use in project planning and evaluation, as well as for comparing governance issues across cases in a conceptually rigorous way.
