On Tiku's robust procedure — a Bayesian insight

Tiku's robust procedure for testing mean and variance from nonnormal universe is examined from the Bayesian viewpoint. The posterior distribution of the scale parameter is derived and then approximated by a Laguerre polynomial expansion while the posterior distribution of the location parameter is approximated by a linear combination of t-distributions. For the example with Darwin's data, the approximations appear to be extremely good.

Explaining the causes of poverty in the West Indies: A cross-cultural comparison

Research into attitudes towards the poor and lay explanations for poverty have heen primarily concerned with the structure and determinants of these attitudes and explanations. Whereas a number of variables — education, religion, ethnic group — have been shown to relate to explanations for poverty, there have only been a few cross-cultural studies. This study set out to compare the explanations adolescents gave for poverty in two West Indian islands — the relatively wealthy island of Barbados and the relatively poor island of Dominica. The overall economic development/prosperity of the two islands, and the extent and visibility of economic inequality between the two islands appeared to account for the numerous national differences. These results are discussed in terms of the social, political and historical differences between the two islands.     

“村村通”广电建设中存在的问题与对策研究

国家对基层广电事业提出了确保"村村通"长期通的新目标,但由于西部基层广电事业自身固有的问题以及在"村村通"建设中产生的新矛盾,完成艰巨任务存在很大困难.而且西部基层广电事业原有的资源条件和经营环境受挤严重,旧的发展方式力不从心,困局渐显.政府主导、行业直管、整合资源、纵深开发是西部基层广电事业改革发展,建立"村村通"长效机制的关键性策略.     

论20世纪中国文学城市叙事中的时间母题

现代性是关于时间意识的观念性阐释,而城市则是现代性的载体与集中呈现。文学中的城市书写与现代性的时间观念紧密相连。时间,既规训了城市的演变和现代人的生存方式,也造成了城市文学叙事的多元化与异质性。20世纪中国文学中的城市叙事,一定程度上就是作家关于时间的体验与想象性的表达。时间成为文学中城市叙事的母题,同时母题有关时间的不同表达方式也带来了城市叙事审美上的嬗变。     

Adaptive wavelet estimation of a density from mixtures under multiplicative censoring

In this paper, a mixture model under multiplicative censoring is considered. We investigate the estimation of a component of the mixture (a density) from the observations. A new adaptive estimator based on wavelets and a hard thresholding rule is constructed for this problem. Under mild assumptions on the model, we study its asymptotic properties by determining an upper bound of the mean integrated squared error over a wide range of Besov balls. We prove that the obtained upper bound is sharp.
