阿拉斯加非凡之旅

This is Alaska,which might as well have been a different country. Seeing the Alaskan Wildlife for the First Time Early morning is the best time to see the brown and black bears.They usually come here to fish for 1)salmon. There were a surprising number of people at the 2)walkway.We sat down by the bridge,looking at the salmon as they 3)raced.In fact,salmon could be found almost anywhere in Alaska,and for a bargain price.I turned my attention to wondering about this miracle of nature.     

The Amazing Summer

<正>Last summer,my friend asked me to go to his hometown to spend the summer vacation.I asked my parents for permission and they said yes.When I got to my friend’s place,I was so surprised because there was a beach near his house.It was so beautiful,and many kids played there.The water was so blue under the sunshine.It was fun to swim in the sea.In the morning,I woke up early and took a walk along the beach,and I could hear

Book review of Amazing Grace

Students who are at risk of dropping out of school can be identified retrospectively as early as third grade on the basis of attendance patterns, academic performance, and behavior. Check &; Connect is a model designed to promote student engagement, support regular attendance, and improve the likelihood of school completion. The program has been used successfully with students attending middle school and high school, with and without disabilities, and in suburban and urban settings. An overview of Check &; Connect, key components of the model, and an application of the model implemented with students who were referred for excessive attendance problems during elementary school years are described. Results from an evaluation of its effectiveness with students who received intervention for at least 2 years (n = 147) showed increased levels of student participation as evidenced by significant increases in the percentage of students whose absences or tardies dropped to or below 5% of the time. In addition, over 90% of the school staff (n = 123) perceived students were showing increased levels of engagement and 87% of school staff reported parents were more supportive of their child's education. Strengths and limitations of the study are discussed in light of rigorous criteria used to examine the effectiveness of social programs. In addition, directions for future research are proposed.

二拍作品体现的社会不和谐因素

阐述了二拍作品中所反映的当时丰十会存在的家庭内部和社会上的不和谐因素,指出不和谐因素主要体现在财重于义、欲重于礼两个方面,提出不和谐现象的实质是晚明时期市民对当时社会思潮的过激反抗。

纺织行业人力资源管理发生可喜变化

大多数企业在市场经济竞争的环境中，对做好人力资源开发与管理工作，认识达到了新的境界，目标进一步明确量化，思路更加清晰可行，初步归纳有以下三条：     

Context 模型奇异测度及其在量化中的应用

使用聚类算法实现 Context 量化不仅可以推广量化器的应用范围,而且可以获得编码性能较理想的优化量化器。然而,聚类算法依赖于相似测度。前期研究中采用的描述长度增量不能完全满足相似测度的各项属性,从而导致聚类结果的性能偏差。因此,提出数学描述特性更好的奇异测度增量作为两个计数向量的相似测度,并说明其相应性质。实验结果证明,使用奇异测度增量作为相似测度,不仅能够保证 Context 量化器的稳定性,而且还获得更佳的编码结果。     

图的补图谱半径和泛圈性

设G=(V,E)是一个n阶简单图,若对于每一个k(3燮k燮n),G都含有长度为k的圈Ck,则称G为泛圈图。利用图的闭包理论研究图的补图谱半径的界,讨论了泛圈图存在的一个谱条件。     

一类单圈图的Merrifield—Simmons指数的极值图

以σ=σ（G）表示Merrifield-Simmons指数,研究连接一个s-pode的单圈图的Merrifield-Simmons指数,刻画了取得极值时的极图。

集合与图

集合论是研究集合的数学理论,也是整个现代数学的基础。集合是集合论中最基本的对象。从集合的概念出发,描述集合论悖论的产生及解决方法,继而将集合区分为良基集和非良基集,探讨了用图来刻画集合的方法。考察集合和图的关系是探究非良基现象的一种有力工具,具有重要的理论意义。
