用人制度改革:高校“去行政化”的切入点

大学欲真正去行政化,就必须改革用人制度。本文提出我国大学用人制度的改革,可以采取民选基础上的职业校长制、聘用制度下的教育职员制和双轨型的教师聘任制三种制度有机结合的方式。

法理作为我国国际私法的法律渊源问题研究

在我国现行法律体制下,法理不是我国法律的渊源,自然也就不是我国国际私法的渊源。但由于国际私法是一门非常特殊的法律部门,无论从法理自身的性质、成文法的不足、各国的国际私法立法及司法实践、国际私法的产生与发展、国际私法的调整对象和学科特点,还是从有利于促进我国与世界各国或者地区友好的民事往来,充分发挥我国在涉外民商事领域的重要作用和影响等诸方面来看,将法理作为我国国际私法的渊源乃当务之急。     

皖江城市带产业转移承接能力分析

承接产业转移是经济欠发达地区发展经济的重要举措,而产业承接力建设是成功实现产业转移的重要手段之一。从产业承接力内涵出发,设计出了包含4个层次,9个二级指标和24个三级指标的产业承接力评价指标体系,通过主成分分析和聚类分析对中部六个地区的产业转移承接力进行评价。结果表明,目前皖江城市带产业吸引力、产业选择力、产业支撑力和产业发展力较弱,产业转移承接能力不强。因此,皖江城市带必须从提升产业转移承接力的四大能力方面采取措施培育其产业承接力。     

基于MFC的《离散数学》实验演示系统的设计与实现

针对离散数学的特点,以MFC和面向对象技术为设计环境,建立了一个可视化的离散数学实验演示系统。该系统实现了抽象概念可视化、界面操作可视化、处理结果可视化的要求。通过演示主合取范式、二部图匹配、群的判定、等价关系、等价类和Krushal算法求最小生成树五个子功能模块,展示了该实验演示系统的功能。     

Recruitment and management development for primary headship

This article seeks to explain the ways in which leadership makes a difference to the quality of instruction in US schools by reviewing research published since 2000. The review of research is presented in three major sections, organised according to the methodology used in each study. The first section looks into quantitative studies that probe the structural relationships among members and activities related to teaching and learning. Primarily drawing on surveys completed by school stakeholders, these studies uncover patterns of influence using advanced statistical methods. The second section summarises findings from qualitative case study research, which provide specific examples of conditions that support the leadership patterns previously identified. The final section offers further explanations of how these patterns of influence operate by examining the alignment of formal and social components of interactions through network methodology.     

Teacher appraisal*

At the heart of the teachers' dispute is not money but management . . . This dispute is about resistance to change in working practices. The essence of education is discipline . . . By resisting the discipline of assessment of their own performance, the teachers stand opposed to the renovation of Britain. That is why in this dispute management must win ‐ and there is the beginning and end of the lazy comparison that some people have been tempted to make with the coal strike. (The Times leader, 19 March 1985).

     

基于主成分分析法对乳制品营养成分分析

乳制品与人们的日常生活息息相关,乳制品的价格各不相同,不同的价格背后所反映出的是营养成分的不同,为了探讨营养成分对乳制品价格的影响,本文在对乳制品进行调查统计的基础上运用主成分分析对乳制品的特征进行提取,实现了主成分分析用于乳制品营养成分定量分析的建模方法.结果表明:乳制品的营养成分特征性指标主要为蛋白质、碳水化合物、脂肪、钠、钙、能量组成;能量和钙则是这些营养成分里面对价格的影响较大的因子.此结论基本上是合理的,对于消费者选购合适的乳制品具有一定的指导作用,可以帮助消费者更为理想地消费乳制品.     

Accelerated matrix recovery via random projection based on inexact augmented Lagrange multiplier method

In this paper, a unified matrix recovery model was proposed for diverse corrupted matrices. Resulting from the separable structure of the proposed model, the convex optimization problem can be solved efficiently by adopting an inexact augmented Lagrange multiplier (IALM) method. Additionally, a random projection accelerated technique (IALM+RP) was adopted to improve the success rate. From the preliminary numerical comparisons, it was indicated that for the standard robust principal component analysis (PCA) problem, IALM+RP was at least two to six times faster than IALM with an insignificant reduction in accuracy; and for the outlier pursuit (OP) problem, IALM+RP was at least 6.9 times faster, even up to 8.3 times faster when the size of matrix was 2 000×2 000.
