浅谈明代贵州司法中的几个特点

明朝的贵州由于民族差异、战争频仍和财政困难等原因，对贵州地区的法律实施产生了一系列的影响，使得贵州法律实施中出现了几个较为突出的现象，比如对贵州土俗的承认、对贵州土官的法律优遇、以钱粮赎罪等等，这是由于贵州在明代的社会历史条件所决定的。     

Nonparametric density estimation from data with a mixture of Berkson and classical errors

The author considers density estimation from contaminated data where the measurement errors come from two very different sources. A first error, of Berkson type, is incurred before the experiment: the variable X of interest is unobservable and only a surrogate can be measured. A second error, of classical type, is incurred after the experiment: the surrogate can only be observed with measurement error. The author develops two nonparametric estimators of the density of X, valid whenever Berkson, classical or a mixture of both errors are present. Rates of convergence of the estimators are derived and a fully data‐driven procedure is proposed. Finite sample performance is investigated via simulations and on a real data example.

Inference in model-based cluster analysis

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.     

A bayesian test for a two-way contingency table using independence priors

One method of testing for independence in a two-way table is based on the Bayes factor, the ratio of the likelihoods under the independence hypothesis H and the alternative hypothesis H. The main difficulty in this approach is the specification of prior distributions on the composite hypotheses H and H. A new Bayesian test statistic is constructed by using a prior distribution on H that is concentrated about the “independence surface” H. Approximations are proposed which simplify the computation of the test statistic. The values of the Bayes factor are compared with values of statistics proposed by Gunel and Dickey (1974), Good and Crook (1987), and Spiegelhalter and Smith (1982) for a number of two-way tables. This investigation suggests a strong relationship between the new statistic and the p-value.

全球化与法律文化重构的研究意义和方法

全球化是包括经济、政治、文化、法律等在内的全方位运动形态。研究全球化与法律文化重构问题 ,要紧扣全球化这个主题 ,分析法律文化同构与异质的具体内涵和基本特质 ,比较东西方法律文化、中外法律文化的种种因素 ,研究和论证法律文化成长和发展的社会基础、价值目标和发展趋势等问题 ,进而探索中国法律文化现代化的认识规律和战略选择。研究方法 :坚持辩证唯物主义与历史唯物主义相结合、宏观分析与微观分析相结合、历史比较与中外比较相结合 ,以法社会学和文化学为观察视角的方法。
