论少数民族本土文化传人的培养--以纳西族的东巴为个案

每一种文化,是一个民族世代积累的智慧结晶,而任何一个民族的传统知识体系、传统文化的传承、弘扬,皆离不开具体的传人来进行薪火相传。它既离不开大众,更离不开一个民间文化精英阶层,他们是传统文化的杰出代表。现代教育体制中对少数民族传统知识体系传承的漠视,导致民间知识精英阶层的衰落,而民间知识精英阶层的衰落,又加速了本土知识传承的中断。以纳西族东巴教祭司东巴为例,深入论述少数民族文化传人培养的重要性。     

东南亚华文文学的移民心态与本土心态

作为汉语世界里的一种话语生产，东南亚华文文学难免受到汉语母体文学（古典或现代）的影响。从历史的层面说，东南亚华文文学的初期阶段基本上是以“侨民文学”的形式发展起来。过去东南亚华文文学曾经是中国文学的支流，是尚未具有主体性的侨民文学，因此中国性的展现是非常自然的。从中国飘洋过海而来的祖辈们把“中国”的记忆传递给下一代，并且一代接一代地传递下去，以致东南亚华文文学始终无法抛开与中国文化藕断丝连的关系。

Minimax estimation of a probability of success under LINEX loss

Minimax estimation of a binomial probability under LINEX loss function is considered. It is shown that no equalizer estimator is available in the statistical decision problem under consideration. It is pointed out that the problem can be solved by determining the Bayes estimator with respect to a least favorable distribution having finite support. In this situation, the optimal estimator and the least favorable distribution can be determined only by using numerical methods. Some properties of the minimax estimators and the corresponding least favorable prior distributions are provided depending on the parameters of the loss function. The properties presented are exploited in computing the minimax estimators and the least favorable distributions. The results obtained can be applied to determine minimax estimators of a cumulative distribution function and minimax estimators of a survival function.     

Multivariate Life Testing in Variably Scaled Environments

This paper examines modeling and inference questions for experiments in which different subsets of a set of k possibly dependent components are tested in r different environments. In each environment, the failure times of the set of components on test is assumed to be governed by a particular type of multivariate exponential (MVE) distribution. For any given component tested in several environments, it is assumed that its marginal failure rate varies from one environment to another via a change of scale between the environments, resulting in a joint MVE model which links in a natural way the applicable MVE distributions describing component behavior in each fixed environment. This study thus extends the work of Proschan and Sullo (1976) to multiple environments and the work of Kvam and Samaniego (1993) to dependent data. The problem of estimating model parameters via the method of maximum likelihood is examined in detail. First, necessary and sufficient conditions for the identifiability of model parameters are established. We then treat the derivation of the MLE via a numerically-augmented application of the EM algorithm. The feasibility of the estimation method is demonstrated in an example in which the likelihood ratio test of the hypothesis of equal component failure rates within any given environment is carried out.     

Statistical inference for olfactometer data

Summary.  Olfactometer experiments are used to determine the effect of odours on the behaviour of organisms such as insects or nematodes, and typically result in data comprising many groups of small overdispersed counts. We develop a non-homogeneous Markov chain model for data from olfactometer experiments with parasitoid wasps and discuss a relation with the Dirichlet–multinomial distribution. We consider the asymptotic relative efficiencies of three different observation schemes and give an analysis of data intended to shed light on the effect of previous experience of odours in the wasps.

Comparison of different estimation techniques for portfolio selection

The main problem in applying the mean-variance portfolio selection consists of the fact that the first two moments of the asset returns are unknown. In practice the optimal portfolio weights have to be estimated. This is usually done by replacing the moments by the classical unbiased sample estimators. We provide a comparison of the exact and the asymptotic distributions of the estimated portfolio weights as well as a sensitivity analysis to shifts in the moments of the asset returns. Furthermore we consider several types of shrinkage estimators for the moments. The corresponding estimators of the portfolio weights are compared with each other and with the portfolio weights based on the sample estimators of the moments. We show how the uncertainty about the portfolio weights can be introduced into the performance measurement of trading strategies. The methodology explains the bad out-of-sample performance of the classical Markowitz procedures.
