This paper analyses the capacity of China's central state to control society and implement its policies at the local level, using as a case study the implementation from 1998 of a major policy initiative—‘closing the pits and reducing coal production’. The aims of this policy were to close down many of the TVE (township and village enterprise) mines, thereby ameliorating China's coal safety record, and to reduce output in order to balance supply and demand, thereby improving the situation of the SOE (state-owned enterprise) coal mines. The paper concludes that, despite some success, the state found it difficult to overcome resistance from a powerful coalition of local cadres, mine bosses, workers and farmers who depended directly or indirectly on the mines for their living. It therefore highlights continuing shortfalls in China's state capacity, particularly in situations where the state is trying to control or influence the distribution of economic rents as between different groups in society.  相似文献

This article examines data from the first‐ever nationwide survey of cybersecurity among American local governments. The data show that these governments are under constant or near‐constant cyberattack, yet, on average, they practice cybersecurity poorly. While nearly half reported experiencing cyberattacks at least daily, one‐third said that they did not know whether they were under attack, and nearly two‐thirds said that they did not know whether their information systems had been breached. Serious barriers to their practice of cybersecurity include a lack of cybersecurity preparedness within these governments and a lack of adequate funding for it. The authors make recommendations to local governments to improve their cybersecurity practice and to scholars for additional research into local government cybersecurity, an area that, to date, has largely been neglected by researchers from the social sciences and computer science.  相似文献

Requirements for a decent life are to be found in the dimensions both of human time and ecological space. While the latter has attracted attention from some global justice theorists, the former is a comparably neglected matter. This paper aims to integrate temporal and ecological perspectives in order to provide an enriched conceptual framework for grasping what global justice means today. We begin by showing that while contemporary political philosophy tends to assume a somewhat undifferentiated conception of time, treating temporal justice as a future-oriented concern distinct from issues of intra-generational justice, there are richer understandings to be found in some influential schools of critical social theory. Drawing then, particularly, on Alf Hornborg’s theory of ‘unequal exchange of time and space’, and supplementing this with insights from David Harvey, we analyse three ways in which disadvantage can be perpetrated in the dimension of time. We then show how those categories of temporal disadvantage broadly correspond with the three basic rights identified by Henry Shue. On this basis, we claim there is a strong argument for regarding temporality as an integral aspect of global justice here and now, for the generation already – although too often precariously – living.  相似文献

Globalisation and climate change in Asia: the urban health impact   总被引:1,自引:0,他引:1  
Asia's economic development successes will create new policy areas to address, as the advances made through globalisation create greater climate change challenges, particularly the impact on urban health. Poverty eradication and higher standards of living both increase demand on resources. Globalisation increases inequalities and those who are currently the losers will carry the greatest burden of the costs in the form of the negative effects of climate change and the humanitarian crises that will ensue. Of four major climate change challenges affecting the environment and health, two—urban air pollution and waste management—can be mitigated by policy change and technological innovation if sufficient resources are allocated. Because of the urban bias in the development process, these challenges will probably register on policy makers' agenda. The second two major challenges—floods and drought—are less amenable to policy and technological solutions: many humanitarian emergency challenges lie ahead. This article describes the widely varying impact of both globalisation and climate change across Asia. The greatest losers are those who flee one marginal location, the arid inland areas, only to settle in another marginal location in the flood prone coastal slums. Effective preparation is required, and an effective response when subsequent humanitarian crises occur.  相似文献

This special issue examines the consequences of the ongoing power transition in the world economy for global regulatory regimes, especially the variation in rising powers' transition from rule-takers to rule-makers in global markets. This introductory article presents the analytical framework for better understanding those consequences, the Power Transition Theory of Global Economic Governance (PTT-GEG), which extends the scope of traditional power transition theory to conflict and cooperation in the international political economy and global regulatory governance. PTT-GEG emphasizes variation in the institutional strength of the regulatory state as the key conduit through which the growing market size of the emergent economies gives their governments leverage in global regulatory regimes. Whether or not a particular rising power, for a particular regulatory issue, invests its resources in building a strong regulatory state, however, is a political choice, requiring an analysis of the interplay of domestic and international politics that fuels or inhibits the creation of regulatory capacity and capability. PTT-GEG further emphasizes variation in the extent to which rising powers' substantive, policy-specific preferences diverge from the established powers' preferences as enshrined in the regulatory status quo. Divergence should not be assumed as given. Distinct combinations of these two variables yield, for each regulatory regime, distinct theoretical expectations about how the power transition in the world economy will affect global economic governance, helping us identify the conditions under which rule-takers will become regime-transforming rule-makers, regime-undermining rule-breakers, resentful rule-fakers, or regime-strengthening rule-promoters, as well as the conditions under which they remain weakly regime-supporting rule-takers.  相似文献

Abstract: In view of the difficulties in extracting quantitative information from burned bone, we suggest a new and accurate method of determining the temperature and duration of burning of human remains in forensic contexts. Application of the powder X‐ray diffraction approach to a sample of human bone and teeth allowed their microstructural behavior, as a function of temperature (200–1000°C) and duration of burning (0, 18, 36, and 60 min), to be predicted. The experimental results from the 57 human bone sections and 12 molar teeth determined that the growth of hydroxylapatite crystallites is a direct and predictable function of the applied temperature, which follows a nonlinear logistic relationship. This will allow the forensic investigator to acquire useful information about the equilibrium temperature brought about by the burning process and to suggest a reasonable duration of fire exposure.  相似文献

The Advanced Technology Program (ATP) collected a unique source of data from highly innovative firms beginning in 1993. These data follow the OECD’s guidelines for collecting innovation data and provide important insights for understanding the innovation process within firms. Although the data are not representative of the population of firms, there is sufficient number of firms in the dataset to test hypotheses and to provide a starting point for calls for innovation metrics. Because of the confidential nature of the data, ATP worked with the National Opinion Research Center (NORC) to create a Data Enclave so that researchers could remotely access the ATP data in a secure environment. To initiate the use of ATP data in the Data Enclave, the ATP program funded researchers to undertake research projects that use ATP data. Other organizations have joined the Data Enclave, including the Department of Agriculture and the Kauffman Foundation.

This article argues that prizes can help stimulate medical innovation, control costs and ensure greater access to new medicines and vaccines. The authors explore four increasingly ambitious prize options to reward medical innovation, each addressing flaws in the current patent system. The first option promotes innovation through a large prize fund linked to the impact on health outcomes; the second option rewards the sharing of knowledge, data, and technology with open source dividends; the third option awards prizes for interim benchmarks and discrete technical problems; and the final option removes the exclusive right to use patented inventions in upstream research in favor of prizes. The authors conclude that a system of prizes to reward drug development would break the link between R&D incentives and product prices, and that such a reform is needed to improve innovation and access to new medicines and vaccines.  相似文献

Ammunition primers consisting of a mixture of lead styphnate, barium nitrate, and antimony (III) sulfide, upon deflagration, lead to the formation of inorganic gunshot residue (GSR). The cations, from their predeflagration form, undergo reduction reactions during burning to form the classic spheroidal, micron-sized particles indicative of GSR. However, the rapidly changing pressure and temperature of the reaction zone implies that the reactions cannot go to completion. In this study, we use a conductivity detector to show that GSR produces an electrical pulse which corroborates the incomplete redox chemistry. We find that the shape of some GSR formed in an electric field also suggests its nonneutral character. Tantalizingly, the formation of GSR might be a result of Coulombic repulsion shattering the molten droplets in to smaller spheroids. Lastly, we suggest that deposition or transfer of GSR could be influenced by static electricity, an area which should be further studied.  相似文献

Noncontact three-dimensional (3D) surface scanning methods are used within forensic medicine to record traumas and other related findings. A structured light scanning technique is one of these methods and the most suitable for the forensic field. An assessment of the efficiency of different structured light scanners with forensic injuries is essential to validate this technique for wound documentation. The purpose of this study was to evaluate the capability of the HP structured light scanner Pro S3 for digitizing open injuries having complicated areas and depths. Fifteen simulated injuries on mannequins were scanned and assessed. Comparisons between 3D and direct wound measurements were made. The results showed that the technique was able to create detailed 3D results of the extensive injuries. Statistical significance tests revealed no difference between the two measurement methods. Because the scanner is applicable for routine work, it should be considered to confirm the same results on real cadavers and actual wounds.  相似文献
