K_(2,r)-单路图谱半径的极限和上界

研究一种直径趋于无穷大的图类K2,r-单路图,利用图谱理论和高等数学求极限的方法,求得当点数n趋于无穷时,K2,r-单路图的谱半径有极限,并且求出了该极限值.进一步验证了该极限值即为K2,r-单路图的一个上界.     

凯恩斯和马克思对失业原因分析的比较

凯恩斯和马克思在对资本主义社会失业问题的分析上有一些相同和类似之处.他们对失业原因分析的一个最大差别是,凯恩斯主要是从人的心理以及人的动机所决定的变量关系上去寻找失业的原因;而马克思的观点是,失业是资本主义生产方式本身对资本主义生产施加的一种限制,失业只是一种相对人口过剩.     

Should Trump Bother with an Education Agenda?

The principal opportunities awaiting the Trump administration in K–12 education are only loosely related to the candidate’s campaign comments about advancing school choice and reducing the federal Education Department. Recent passage of the Every Student Succeeds Act signals that Congress will be loath to re-open the major federal K-12 programs for amendment. Bright opportunities away in connection with the Perkins Act, special education and the Institute of Education Sciences (IES), as well as various domains--beginning with the Office for Civil Rights--that beg for strategic deregulation.

力量训练和耐力训练的生理基础

无论是对于大众健身还是专业训练,目前一致认为,力量训练能够促使肌肉体积增加、力量增长,而耐力训练则可以改变机体的有氧代谢水平。此外,如果将力量训练跟耐力训练无间隔交叉进行则会产生相互干扰的效果。旨在通过对这两种训练各自的信号转导途径进行分析以及互相干扰现象进行系统地阐述,以期能够为大众健身以及专业训练的人群在训练计划的安排上提供一个合理的理论依据及建议。     

回归后香港中学体育课程建设的新特点

通过对香港回归前的课程指引和内地执行的体育教学大纲的比较研究 ,香港回归祖国后新编拟的中学体育科课纲要在教学目的、内容和计划性方面都表现了新特点。这为地区间学校体育相互交流、协调发展提供了共识和新的起点 ,也有利于中华体育的共同发展。     

It takes a village: Managing conflict in the K-12 classroom

This project examines the classroom conflict management challenges K–12 teachers experience. The U.S. Department of Education released a January 2014 bulletin outlining their classroom conflict management position, providing teachers recommendations without providing tools and conflict management knowledge to effectively implement the recommended programs. Understanding the nature and components of conflict better enables conflict managers (i.e., teachers) to effectively manage and resolve conflict. Understanding the challenges teachers face when managing conflict enables practitioners to create practical recommendations for conflict resolution education. This project analyzed data from four focus groups of K–12 teachers (n = 21) from the northern Midwest. Teachers identified structural challenges (i.e., lack of parental or administrative support) to managing conflict. Findings indicate that comprehensive conflict management training and productive communication between all levels of the system are necessary to effectively manage conflict in the classroom.
