In this paper I comment critically on the dominant form of appropriation of Marx's theory of class and the state within what one might call the‘conventional’sociology of class in the post-war period. I argue that the typical mode of interpretation and assimilation has been highly selective and has taken a form that has rendered the proposed theory particularly vulnerable to sociological criticism especially in the light of changes in the structure of capitalist social formations in the twentieth century, although there is no suggestion here that the selectivity has been intentional. I contrast the dominant sociological construction and critique of Marx's theory of classes and the state with an interpretation drawn from recent scholarship, arguing that it is possible to document the contention that most theorems hitherto regarded both as central to Marx's analysis and as particularly susceptible to criticism were actually revised by Marx himself in his maturity as part of a more general process of intellectual formation and theoretical development. Many of these revisions have been widely discussed in debates within the world of Marx scholarship and some have undoubtedly been noticed in sociological interpretations of Marx. However, they have not led to the major overall reinterpretation of Marx's theory of class that is now long overdue. 相似文献

Environmental criminologists have correlated crime patterns with the environmental and physical layout of places where crimes occur. This paper reports on some of the findings derived from a major research carried out in Tehran, focusing on the link between built environment and residential burglary. After a brief review of crime prevention approaches in the built environment and their theoretical basis, the paper examines how burglars select their targets, and investigates the significance of geographical distance and target hardening for crime prevention. It shows the limitations of distance and target hardening as deterrents, their potential impact on deepening the city's socio-spatial divide, and their negative implications for the quality of the urban environment. 相似文献

Cities in developing countries are facing a double dilemma. On one hand, the urban population is growing rapidly, causing a huge increase in demand for waste management services. On the other hand, the traditional public sector is failing to respond to the increased demand for service. The public sector is constrained by resource and institutional limitations. It is often proposed that the solution lies in private sector participation. It is expected that the private sector, with its dynamism and flexibility, may fill in the service delivery gaps by forming partnership with the public sector. However, a third tier—the people—is often overlooked in the service delivery framework. Citizens can contribute significantly to service delivery. They can support the private sector with payment of service charges. But more importantly, they can play an active role in improving accountability and service quality of both public and private sector. This radical shift in people's role, from passive service receivers to active service partners, however, may not occur endogenously. External help from facilitating agencies may enable the public and private sector to form partnership with people for better service delivery. This article examines the role of facilitating agencies in developing tripartite partnership for solid waste management service in Bangladesh. The key lessons learned are: a number of obstacles prevented spontaneous partnership among the public sector, private sector and people; facilitating agencies were able to overcome the obstacles to form partnership of the three; and, the tripartite arrangement resulted in higher accountability and better service delivery. 相似文献

The Assessment of Probability Distributions from Expert Opinions with an Application to Seismic Fragility Curves 总被引:2,自引:0,他引:2
A method is developed for estimating a probability distribution using estimates of its percentiles provided by experts. The analyst's judgment concerning the credibility of these expert opinions is quantified in the likelihood function of Bayes'Theorem. The model considers explicitly the random variability of each expert estimate, the dependencies among the estimates of each expert, the dependencies among experts, and potential systematic biases. The relation between the results of the formal methods of this paper and methods used in practice is explored. A series of sensitivity studies provides insights into the significance of the parameters of the model. The methodology is applied to the problem of estimation of seismic fragility curves (i.e., the conditional probability of equipment failure given a seismically induced stress). 相似文献

We derive closed form expressions for the first two moments of order statistics from the sine distribution. For the higher moments, a recurrence relation is given. We also give a recurrence relation for the product moments. These relations will be useful for moment computations based on ordered data. 相似文献

Sharma (1977) and Aggarwal et al. (2006) considered non circular construction of first- and second-order balanced repeated measurements designs. Sharma et al. (2002) constructed circular first- and second-order balanced repeated measurements designs only for a class with parameters (v, p = 3n, n = v 2) and also showed its universal optimality. In this article, we consider circular construction of first- and second-order balanced repeated measurements designs and strongly balanced repeated measurements designs by using the method of cyclic shifts. Some new circular designs with parameters (v, p, n) for cases p = v, p < v and p > v are given. 相似文献

This paper deals with a regression model for several vari¬ables under the assumption that the errors have a multivariate t-distribution. The parameters of the model, the regression parameters, as well as the scale parameters and the degress of freedom of the error variable are estimated and the estimation procedure is illustrated by a numerical example, Also, the prop¬erties of the estimators and tests for the regression parameters are discussed. 相似文献

It i s well known that even if the sample observations are correlated and not normal, the sample mean is normal in 1arge samples. But how large is large? This question i s investigated in this paper. In particular , the relation between the rate of convergence and the correlation property of the observations i s explored. It i s observed that the correlation, in general, retards the rate of convergence. 相似文献
