西南地级城市新建本科师范院校发展定位的若干思考

川、渝、滇、黔辖区内一些地级城市所属的新建本科师范院校在高等教育大众化进程中实现了多个建设目标超常规发展,已成为中国高等教育的重要组成部分,承载着地方经济文化发展和人才培养的重要使命,更是西南地级城市建设的新名片。但这些新建地方高校在发展定位方面存在诸多问题,影响并制约了这些新建高校可持续发展战略。因此,探析西南地级城市新建师院发展定位的基本依据、发展定位的基本原则及基本内容势在必行。     

Invariant co-ordinate selection

Summary.  A general method for exploring multivariate data by comparing different estimates of multivariate scatter is presented. The method is based on the eigenvalue–eigenvector decomposition of one scatter matrix relative to another. In particular, it is shown that the eigenvectors can be used to generate an affine invariant co-ordinate system for the multivariate data. Consequently, we view this method as a method for invariant co-ordinate selection . By plotting the data with respect to this new invariant co-ordinate system, various data structures can be revealed. For example, under certain independent components models, it is shown that the invariant co- ordinates correspond to the independent components. Another example pertains to mixtures of elliptical distributions. In this case, it is shown that a subset of the invariant co-ordinates corresponds to Fisher's linear discriminant subspace, even though the class identifications of the data points are unknown. Some illustrative examples are given.     

Order statistics from trivariate normal and -distributions in terms of generalized skew-normal and skew- distributions

We consider here a generalization of the skew-normal distribution, GSN(λ₁,λ₂,ρ), defined through a standard bivariate normal distribution with correlation ρ, which is a special case of the unified multivariate skew-normal distribution studied recently by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574]. We then present some simple and useful properties of this distribution and also derive its moment generating function in an explicit form. Next, we show that distributions of order statistics from the trivariate normal distribution are mixtures of these generalized skew-normal distributions; thence, using the established properties of the generalized skew-normal distribution, we derive the moment generating functions of order statistics, and also present expressions for means and variances of these order statistics.Next, we introduce a generalized skew-t_ν distribution, which is a special case of the unified multivariate skew-elliptical distribution presented by Arellano-Valle and Azzalini [2006. On the unification of families of skew-normal distributions. Scand. J. Statist. 33, 561–574] and is in fact a three-parameter generalization of Azzalini and Capitanio's [2003. Distributions generated by perturbation of symmetry with emphasis on a multivariate skew t distribution. J. Roy. Statist. Soc. Ser. B 65, 367–389] univariate skew-t_ν form. We then use the relationship between the generalized skew-normal and skew-t_ν distributions to discuss some properties of generalized skew-t_ν as well as distributions of order statistics from bivariate and trivariate t_ν distributions. We show that these distributions of order statistics are indeed mixtures of generalized skew-t_ν distributions, and then use this property to derive explicit expressions for means and variances of these order statistics.     

Finite normal mixture copulas for multivariate discrete data modeling

A new family of copulas is introduced that provides flexible dependence structure while being tractable and simple to use for multivariate discrete data modeling. The construction exploits finite mixtures of uncorrelated normal distributions. Accordingly, the cumulative distribution function is simply the product of univariate normal distributions. At the same time, however, the mixing operation introduces association. The properties of the new family of copulas are examined and a concrete application is used to show its applicability.     

Forecasting obesity trends in England

Summary.  Forecasts of trends in obesity in England for 2010 are produced by treating the available data, which contain the proportions of the population, categorized by age and sex, falling into different body mass index ranges, as compositional data sets, so that the implicit simplex restrictions are automatically satisfied. Forecasts are calculated by using linear trend models for the log-ratio transformations and are accompanied by prediction regions. The advantages of treating data on proportions compositionally are emphasized and compared with forecasts that have been obtained by ignoring this restriction.     

反思与重构:对结合犯概念的再思考

对结合犯概念的揭示应注意以下几个方面:不能脱离结合犯的初始意义,应反映结合犯的本质内涵和立法目的,不能脱离法律的实证规定,不能混淆规范刑法学与本体刑法学的界限,不能脱离犯罪成立的理论体系.所谓结合犯是指立法者基于特定立法目的的考虑,将两个具有内在联系性的犯罪(构成要件)规定为独立犯罪(构成要件)的情况.

综合性大学举办教师教育存在的问题及对策

综合性大学举办的教师教育已经成为我国教师教育的重要组成部分。但目前它仍处于探索阶段,不可避免地存在如下缺陷:学术性和师范性难以兼顾,课程设置有待优化,综合性大学与师范院校缺乏合作,教育专业与非教育专业缺乏双向交流等。要推进综合性大学教师教育的改革与发展,综合性大学可采取如下举措:平衡学术性与师范性,推进教师教育创新;优化教师教育课程设置,促进教师教育课程改革;努力实现资源共享、优势互补,探索教师教育发展道路;加强专业间的合作,促进融合发展。
