This article documents and analyses a reconstructed Weberian conception of the problem of suffering. In this setting a focus is brought to how the problem of suffering is constituted in the dynamic interplay between, on the one hand, the compulsion to impose rational sense and order on the world, and on the other, the necessity to find a means to satiate charismatic needs. The discussion highlights Weber's account of the tendency for problems of suffering to increase in volume and scale along with the intensification and spread of modern processes of rationalization. It offers a case for the development of further sociological inquiries into the role played by experiences of the problem of suffering within the dynamics of social and cultural change. 相似文献

This paper proposes diagnostic plots for regression variance functions. It shows how to extend graphical methodology that uses Bayesian sampling for checking the regression mean function to also check the variance function. Plots can be constructed quickly and easily for any model of interest. These plots help to identify model weaknesses and can suggest ways to make improvements. The proposed methodology is illustrated with two examples: a simple linear regression model to fix ideas, and a more complex study involving count data to demonstrate the potential for wide application. 相似文献

Practical Bayesian data analysis involves manipulating and summarizing simulations from the posterior distribution of the
unknown parameters. By manipulation we mean computing posterior distributions of functions of the unknowns, and generating
posterior predictive distributions. The results need to be summarized both numerically and graphically.
We introduce, and implement in R, an object-oriented programming paradigm based on a random variable object type that is implicitly
represented by simulations. This makes it possible to define vector and array objects that may contain both random and deterministic
quantities, and syntax rules that allow to treat these objects like any numeric vectors or arrays, providing a solution to
various problems encountered in Bayesian computing involving posterior simulations.
We illustrate the use of this new programming environment with examples of Bayesian computing, demonstrating missing-value
imputation, nonlinear summary of regression predictions, and posterior predictive checking. 相似文献

Very Public Scandals: Nongovernmental Organizations in Trouble 总被引:1,自引:0,他引:1
Gibelman Margaret Gelman Sheldon R. 《Voluntas: International Journal of Voluntary and Nonprofit Organizations》2001,12(1):49-66
This paper analyzes, from a cross-national perspective, publicized incidents of alleged wrongdoing on the part of nongovernmental organizations (NGOs). Data were derived from daily, weekly, or monthly newspapers and special nonprofit newsletters accessible through websites. Analysis of media reports of scandals involving NGOs was conducted to identify issues and trends in governance and management problems associated with this sector. The paper focuses on NGOs involved in the financing or delivery of health and human services. After highlighting some of the precedent-setting cases of NGO improprieties in the United States during the 1990s, prominent global cases of wrongdoing during the period 1998–2000 are reviewed. The underlying problems that allowed these cases to occur and their implications regarding NGO credibility and public trust are identified, and strategic options for enhancing accountability presented. 相似文献

Wavelet Threshold Estimators for Data with Correlated Noise 总被引:1,自引:0,他引:1
Iain M. Johnstone & Bernard W. Silverman 《Journal of the Royal Statistical Society. Series B, Statistical methodology》1997,59(2):319-351
Wavelet threshold estimators for data with stationary correlated noise are constructed by applying a level-dependent soft threshold to the coefficients in the wavelet transform. A variety of threshold choices is proposed, including one based on an unbiased estimate of mean-squared error. The practical performance of the method is demonstrated on examples, including data from a neurophysiological context. The theoretical properties of the estimators are investigated by comparing them with an ideal but unattainable `bench-mark', that can be considered in the wavelet context as the risk obtained by ideal spatial adaptivity, and more generally is obtained by the use of an `oracle' that provides information that is not actually available in the data. It is shown that the level-dependent threshold estimator performs well relative to the bench-mark risk, and that its minimax behaviour cannot be improved on in order of magnitude by any other estimator. The wavelet domain structure of both short- and long-range dependent noise is considered, and in both cases it is shown that the estimators have near optimal behaviour simultaneously in a wide range of function classes, adapting automatically to the regularity properties of the underlying model. The proofs of the main results are obtained by considering a more general multivariate normal decision theoretic problem. 相似文献

This paper considers the activities of senior managers as isomorphic with the activities of actors. It takes performing as not a matter of metaphor, but a matter of form; life at the top of an organization is intrinsically theatrical; each of us is blessed or cursed with histrionic sensibility. Proceeding by way of a comparison of Edmund Kean and Lee lacocca it touches upon matters of text and interpretation, rehearsal and performance and the importance of individuation. The argument – such as it is – is that both Kean and lacocca perform themselves, the former's Richard III, the latter's Chrysler being the fullest realizations of that which was, hitherto, inchoate and emergent. The final part of the paper is concerned with the implications of this perspective for education, training and development; current management education appears geared to reduce rather than to promote individuality. Techniques are imposed and answers are provided and the entire educational performance revolves around teachers as performers rather than managers as performers. The way to become a management star, it is suggested, is to do managing, not simply to be audience for academic stars. 相似文献

It is shown that Greenwood's statistic for uniformity and the Hahn-Shapiro and Stephens statistics for exponentiality with known origin are equivalent. It is also shown that the distribution of the Shapiro-Wilk statistic for testing the hypothesis of exponentiality with unknown origin is obtainable from the distribution of Greenwood's statistic. 相似文献
