建构主义学习理论与CAI外语教学模式

指出从认知发现理论发展而来的建构主义是计算机辅助教学(CAI)的理论基础。阐释了建构主义所倡导的以学习者为中心的学习原理及建构主义的主要特征(情境、合作与交流、意义建构)及其对CAI外语教学具有重要的理论指导意义。从而指出以现代教育理论为基础,采用改善传统教学环境与内容的现代教育手段与模式会成为外语教学改革的新突破。     

Estimation of global temperature fields from scattered observations by a spherical-wavelet-based spatially adaptive method

Summary.  The paper considers the problem of estimating the entire temperature field for every location on the globe from scattered surface air temperatures observed by a network of weather-stations. Classical methods such as spherical harmonics and spherical smoothing splines are not efficient in representing data that have inherent multiscale structures. The paper presents an estimation method that can adapt to the multiscale characteristics of the data. The method is based on a spherical wavelet approach that has recently been developed for a multiscale representation and analysis of scattered data. Spatially adaptive estimators are obtained by coupling the spherical wavelets with different thresholding (selective reconstruction) techniques. These estimators are compared for their spatial adaptability and extrapolation performance by using the surface air temperature data.

高校大学生社会实践活动功能初探

高校大学生社会实践活动作为一种生动有效的培养人才的重要途径,已经显示出它在大学生的思想教育、专业学习和能力培养等方面的综合效益。其基本功能主要表现在五个方面,即思想教育功能、深化教学功能、实践检验功能、社会服务功能、劳动助学功能。     

The empirical analysis of the -bilateral optimized combinatorial auction model

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism.     

现代文学的“游子还乡”题材

现代文学中“游子还乡”模式演变 ,由传统的大团圆嬗变为归乡再度离乡。归乡源于知识分子的启蒙冲动 ,再度离乡则因其未能达到民众的官财双重价值标准。知识分子主体性在乡间无法确立 ,启蒙价值难以实现 ,不得不再度离乡 ,在寻找中保持其独特性     

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

固定效应部分线性变系数面板模型的快速有效估计

本文将最小二乘支持向量机(LSSVM) 和二次推断函数法(QIF) 相结合，为个体内具有相关结构的固定效应部分线性变系数面板模型提供了一种新的快速估计方法；在一定的正则条件下，论证了参数估计量的渐近正态性和非参数估计量的收敛速度；采用Monte Carlo模拟考察了估计方法在有限样本下的表现并将估计技术应用于现实数据分析。该方法不仅保证了估计的有效性和统计推断力，而且程序运行速度得到较大幅度提升。     

论高校学报质量函数关系

高等学校学报质量是一个整体概念,要在策划、选题、审稿、编校、装帧设计、印制、发行等各个环节都以质量为本,以求达到最佳质量效果。每一个环节的质量形成了一个质量体系,这个质量体系包含多个参数组成,每一个参数对高等学校学报质量作用不同,从而这些参数与学报整体质量形成函数关系。
