个人语码转换的动机研究

在言语交际中语码转换现象非常普遍。对语码转换的动机研究更是涵盖了社会语言学、语用学、心理学等各个学科角度。基于前人的理论研究成果,本文认为个人语码转换的深层动机受控于社会规则和话语主体意识等二元因素。     

试析仲裁简易程序的适用条件

虽然我国各仲裁委员会在实践中大量适用仲裁简易程序,但我国法学理论界却很少对其时代内涵进行界定,对其适用条件也缺乏探讨,因而制约了仲裁简易程序的研究和发展。本文在分析仲裁简易程序时代内涵的基础上,从主观条件和客观条件两方面对仲裁简易程序的适用条件进行了探讨,建议规范我国仲裁简易程序的适用条件,实现仲裁简易程序的和谐价值取向。     

Resistant orthogonal procrustes analysis

In this paper two alternative loss criteria for the least squares Procrustes problem are studied. These alternative criteria are based on the Huber function and on the more radical biweight function, which are designed to be resistant to outliers. Using iterative majorization it is shown how a convergent reweighted least squares algorithm can be developed. In asimulation study it turns out that the proposed methods perform well over a specific range of contamination. When a uniform dilation factor is included, mixed results are obtained. The methods also yield a set of weights that can be used for diagnostic purposes.

根据篮球运动竞赛的特点,采用文献资料法、观察统计法、专家访谈等方法从裁判员执裁经验、裁判员心理素质、裁判员对规则和裁判法的掌握等方面进行分析探讨,旨在找出影响篮球裁判员执裁水平的因素,以明确优秀篮球裁判员能力发展的要求。     

论"规矩"与"方圆"语境下干部践行荣辱观的文化自觉

在全社会树立社会主义荣辱观，重点和关键在于干部。广大干部要从传统与现代、整体与个人、大是与小非、内质与外化等关系层面的理解上，形成自觉践行荣辱观的文化自觉；要以“规矩”与“方圆”的逻辑理念构建干部新形象，即努力铸造一种内在的恪守原则性、纪律性的“内方”形象，外在的体现和谐性、团结性的“外圆”形象，以及整体优化的原则性、和谐性兼备的“方圆统一”的道德人格喻义形象。

A High Speed Detection Scheme for Point Targets in a Multitarget Environment

The purpose of this paper is to develop a high speed detection scheme for moving and / or stationary point targets in a multitarget environment as registered in an IR image sequence. An iterative approximate 3-D line searching algorithm based upon the geometric representation of lines (for non-maneuvering targets in space) in a 3-D space is derived. The convergency of the algorithm is proved. An analysis is performed of the theoretical detection performance of the algorithm. The statistical experiment results show high effectiveness and computational efficiency of the algorithm in the case of low SNR. The idea may be employed to satisfy the real-time processing requirement of an IR system.     

SWITCHING CONTROL： FROM SIMPLE RULES TO COMPLEX CHAOTIC SYSTEMS

This paper reviews and introduces some simple switching piecewise-linear controllers, which can generate complex chaotic behaviors from simple switching systems.The mechanism of simple switching rules creating complex chaotic behaviors is further investigated.
