Floyd算法分析与演示系统设计

路径分析是网络分析最基本的问题,其核心是对最短路径的求解,其求解算法的优劣决定相关软件的性能,通过对F1oyd算法分析,比较了各种算法的时间复杂度,并使用Java语言设计演示程序说明了Floyd算法的实现机制。     

C++面向对象程序设计中的二义性及其解决方法

C++语言是一种使用非常广泛的计算机编程语言,它支持过程化程序设计、数据抽象、面向对象程序设计、制作图标等多种程序设计风格.在C++面向对象的程序设计中,多继承使用频繁,然而使用多继承容易出现二义性问题.本文结合自己这几年的教学经验,通过分析教材和一些参考书中的二义性例题,总结出C++中容易出现二义性的情况及解决方法.     

改革30年来企业管理思想演进路径探析

改革开放30年企业管理思想随着中国经济体制改革同步演进,但远远落后于经济发展的步伐和节奏。企业管理思想受到国家工业经济战略布局思路、管理学科建设水平等结构性影响,企业管理思想演进呈现出西方管理思想一元论、中国管理思想丛林化和企业管理现实隔阂化的局面,同时企业管理思想演进一直呈现出科学性、开放性和人本化的路径趋势。     

特定条件下路径选通的软件设计

本文介绍了在某些条件限制下路径选通的算法及软件设计．路径选通采取矩阵多次相乘的方法。     

QUASI-CRITICAL PATH METHOD FOR CONTROLLING THE START-TIME OF ACTIVITY

A new idea of Quasi-Critical Path has been defined in terms of the thoughtof Critical Path for the network method.The paper studies the time control problem of anetwork with forced start-time activity by both the optimal criterion of minimal reducedtime and the concept of Quasi-Critical Degree of activity,and proposes a feasible heuristicalgorithm.Another simpler algorithm is also presented,which can be realized inmicrocomputer.     

学术机构引证中的中介关系

本文研究学术机构引证网络中的中介关系,识别和分析以中间人作为纽带的中介路径以及中介模式。选取信息计量领域机构数据,依据P(Top 10%)指数将学术机构划分为“强”“中”“弱”三个学术实力等级,结合中间人中介关系分析,得出三条主要知识交流路径,按照显著程度,依次为“中→弱”“弱→弱”和“强→弱”。中介模式方面,“强”等级中间人机构发挥主导中介作用。显著路径末端的机构与对应的始端机构具有潜在的知识交流需求,双方可在重合的研究主题和研究方向上推进交流合作。图6。表8。参考文献26。     

Relationships between student cognitions and their effects on study strategies

Using Vermunt's model [Vermunt, J. D. (1998). The regulation of constructive learning processes. British Journal of Educational psychology, 68, 149–171] of self-regulated learning as a conceptual framework, this study aims to contribute to the development of finer grained models of higher education students' learning by (1) investigating causal relationships between three student cognitions which feature prominently in the research literature: self-efficacy, conceptions of learning and attributions for academic success and by (2) researching both the direct and indirect effects of these student cognitions on first year university students' study strategies. To that end a model was developed, respecified, tested, and cross validated using path analyses. Results show that within an educational context learning conceptions are fundamental student cognitions since they directly and/or indirectly influence students' self-efficacy, attributions for academic success, and study strategy.     

立法缺位状态下公立高校纠纷解决的路径分析

受诸多方面因素的影响,高校管理领域存在着立法缺位的现象,这种现象直到教育部2003年提出依法治校之后也并没有从根本上消失。高校发生的诸种管理纠纷就是置身于这种场景之下的。司法是解决高校行政纠纷的一种重要手段,但是它在解决纠纷时面临着许多突出的问题。对该类纠纷的根本性解决,不能单纯依靠司法审查制度,而应该在完善司法审查制度的同时,探求更为根本的路径。     

Stimulating professional learning through teacher evaluation: An impossible task for the school leader?

Providing effective feedback through teacher evaluation is a complex task for the school leader. Many authors state that teacher evaluation does not contribute to teachers’ professional learning. Few studies focus on the specific leadership variables that contribute to effective teacher evaluation. This study explores the importance of transformational and instructional leadership for the feedback utility and teachers’ professional learning. The results of regression and path analyses showed that leadership directly influences the feedback utility and indirectly influences teachers’ professional learning. This study demonstrates the importance of school leadership for effective teacher evaluation and highlights its usefulness for teachers’ professional learning.     

体育强国视域下举办2022年北京-张家口冬奥会的现实路径探索

体育强国战略的提出在不同历史时期都为我国体育事业的发展指明了方向。采用文献资料、逻辑推理等方法对体育强国的多维定义加以概括,对体育强国与2022年冬奥会的内在联系进行探索。建议：积极筹备北京张家口冬奥会的赛事建设,打造一届“无与伦比”的中国冬奥,构建中国冰雪口碑;鼓励冰雪相关产业发展,推动我国冰雪产业自主研发,开辟中国冰雪产业经济大时代;加强冰雪人才培养,鼓励群众参与冰雪,体育强国与群众强身并举,推进我国建成体育强国目标的实现。
