ABSTRACTDrawing on social histories of rumour, this article challenges notions of white and Afrikaner homogeneity which persist in the scholarship on late and post-apartheid South Africa. In so doing, it demonstrates the revisionist potential of rumour as a historical source, while reinserting class in a scholarship which privileges race as salient historical feature. The article focuses on Arrie Paulus, apartheid South Africa’s most prominent white trade unionist, infamous as the personification of working-class racism. Yet this defender of race-based privilege and staunch Afrikaner nationalist was haunted by a rumour: Paulus, it was whispered, was not actually white. The rumour circulated in reform-era South Africa and persists in the post-apartheid present. By examining the rumour surrounding Paulus’s racial and ethnic origins in terms of the functions it fulfilled within the particular contexts in which it appeared, this article exposes longstanding tensions around the politics of class characterizing Afrikaner society since the 1970s. 相似文献

Empowerment has become a widely used management term in the last decade or so, though, in practical terms, it shares the ambiguity of its predecessors in the HRM tradition. This paper sets out to unravel the web of meaning surrounding empowerment to show what a contested concept it is, and hence why its application in organizational settings is fraught with misunderstanding and tension. It does so by taking an approach that contributes to the examination of HRM discourse and management rhetoric. To demonstrate the ambiguity of empowerment as a concept, the paper reviews the various ways in which the term has been used across non-management disciplines (women, minority groups, education, community care, politics), culminating with a review of the use of empowerment in contemporary management theory. The paper concludes that organizations and managers have chosen to coin a phrase which is open to different, sometimes contradictory, meanings and which, when applied, evokes both subjective attitudes and objective behaviour, means different things in varying contexts, and is affected fundamentally by individual differences in perception and experience. Unless organizations offer clear operational definitions when using empowerment, instead of purely acquiescing to a vague and seductive version of the concept, they are abdicating responsibility for the unpredictable consequences that result. 相似文献

Inference in model-based cluster analysis 总被引:6,自引:0,他引:6

A new approach to cluster analysis has been introduced based on parsimonious geometric modelling of the within-group covariance matrices in a mixture of multivariate normal distributions, using hierarchical agglomeration and iterative relocation. It works well and is widely used via the MCLUST software available in S-PLUS and StatLib. However, it has several limitations: there is no assessment of the uncertainty about the classification, the partition can be suboptimal, parameter estimates are biased, the shape matrix has to be specified by the user, prior group probabilities are assumed to be equal, the method for choosing the number of groups is based on a crude approximation, and no formal way of choosing between the various possible models is included. Here, we propose a new approach which overcomes all these difficulties. It consists of exact Bayesian inference via Gibbs sampling, and the calculation of Bayes factors (for choosing the model and the number of groups) from the output using the Laplace–Metropolis estimator. It works well in several real and simulated examples. 相似文献

The utilization of DNA evidence in cases of forensic identification has become widespread over the last few years. The strength of this evidence against an individual standing trial is typically presented in court in the form of a likelihood ratio (LR) or its reciprocal (the profile match probability). The value of this LR will vary according to the nature of the genetic relationship between the accused and other possible perpetrators of the crime in the population. This paper develops ideas and methods for analysing data and evaluating LRs when the evidence is based on short tandem repeat profiles, with special emphasis placed on a Bayesian approach. These are then applied in the context of a particular quadruplex profiling system used for routine case-work by the UK Forensic Science Service. 相似文献

The literature on demographic determinants of attitudes towards taxation was briefly reviewed. Whereas most previous concerned the relationship between such things as income, vote etc. and tax attitudes, this study examined the relationship between Protestant Work Ethic beliefs, social value systems and attitudes toward taxation. It was demonstrated that subjects who strongly endorsed the Protestant Work Ethic were more opposed to taxation than those who did not strongly endorse these beliefs. Further many of the instrumental and terminal value systems of subjects who were pro-taxation were significantly different from those who were anti-taxation. The results are discussed in terms of the psychology of lay-economic beliefs and implications for social change were noted. 相似文献

Despite not being grounded in the classic nation-building dynamic of citizenship identified by T.H.Marshall, EU citizenship offers social rights and welfare protection to non-nationals on a principle of non-discrimination. We narrate a creeping process of retrenchment by which European member states have used policy strategies to undermine this principle, by transforming the unique idea of free movement of persons in the EU to just another form of “immigration” which can be subject to selectivity and exclusion. As Europe’s multiple recent crises have unfolded, political resources were found to effect this transformation tangibly via reshaping access to welfare for EU citizens. Focusing on the cases of the UK and Germany, we discuss how, despite their distinctive welfare regimes and labour market systems, these two countries have led the way toward a dismantling of non-discrimination for EU citizens and effectively the end of the anomalous ‘post-national’ dimension of European citizenship. 相似文献

Randomised controlled trials are considered the gold standard in trial design. However, phase II oncology trials with a binary outcome are often single-arm. Although a number of reasons exist for choosing a single-arm trial, the primary reason is that single-arm designs require fewer participants than their randomised equivalents. Therefore, the development of novel methodology that makes randomised designs more efficient is of value to the trials community. This article introduces a randomised two-arm binary outcome trial design that includes stochastic curtailment (SC), allowing for the possibility of stopping a trial before the final conclusions are known with certainty. In addition to SC, the proposed design involves the use of a randomised block design, which allows investigators to control the number of interim analyses. This approach is compared with existing designs that also use early stopping, through the use of a loss function comprised of a weighted sum of design characteristics. Comparisons are also made using an example from a real trial. The comparisons show that for many possible loss functions, the proposed design is superior to existing designs. Further, the proposed design may be more practical, by allowing a flexible number of interim analyses. One existing design produces superior design realisations when the anticipated response rate is low. However, when using this design, the probability of rejecting the null hypothesis is sensitive to misspecification of the null response rate. Therefore, when considering randomised designs in phase II, we recommend the proposed approach be preferred over other sequential designs. 相似文献
