论科学社会主义三次重大理论创新

科学社会主义150多年的历史发展过程,经历了三次重大理论创新:第一次重大理论创新是科学社会主义理论的创立,马克思恩格斯揭示了社会发展的"两个必然性",找到了实现社会主义的阶级动力和现实途径,描绘了未来科学社会主义的初步蓝图。第二次重大理论创新是列宁主义和毛泽东思想的形成,开创了马克思主义俄国化与中国化的历程,找到了适合俄国和中国国情的革命道路,使科学社会主义由理论变为实践。第三次重大理论创新是邓小平理论和"三个代表"重要思想的确立,第一次比较系统地回答了在经济文化比较落后的国家如何建设和发展社会主义,以及建设一个什么样的党和怎样建设的问题。这三次重大理论创新既一脉相承,又与时俱进,体现了科学社会主义的连续性和间断性,丰富和发展了科学社会主义理论。     

大学英语分层教学探索

学生入校时的英语水平参差不齐使高专大学英语教学改革势在必行。根据现代教育理论、高专教育英语课程教学基本要求和大学英语分层教学的客观必要性 ,我校从 2 0 0 0年开始在非英语专业学生中实施了两年多的分层教学。实践证明我们的改革是成功的 ,我们的分层教学取得了预期的效果     

“角笔”的发现与研究

角笔是一种２０世纪６０年代才被重新发现的古老的书写工具,在中、韩、日等国的文献中,都有使用角笔的文献发现。角笔用象牙、木、竹等制成,以在纸上划出凹痕的形式记录信息。在日本,角笔最早见于奈良时代,主要用于在“训点”读佛经、汉诗文等时加注各种训读符号。角笔的渊源,则可以追溯到唐代以前的中国,但中国角笔实物的发现,则待进一步的调查。     

多媒体教学手段在《理论力学》讲课中的应用

二十世纪后期电脑和信息技术在经济建设和科学技术的各个领域得到广泛的应用.在这样的形势下,高等学校中也面临着教育改革的迫切任务,如何在各门课程中,高质量和高效率地培养学生,已成为现实的问题.本文涉及<理论力学>课程的讲课方式的改革,介绍我们采用多媒体手段进行<理论力学>讲课的实践和体会,并提出一些有关的看法.     

论中国“幽默”的理论形态——兼论林语堂的“幽默”说

“幽默 (Humor)”引入中国文论 70年 ,翻译者当年辞不达意的无奈被忘却 ,成了典型的理论误区。幽默的发生有重要的人类学机制 ,健全的人类族群都有幽默 ,但有民族文化差异 ,在那些由于同样原因使之无法发挥作用的地方是不能生搬硬套的。中国传统幽默及其理论自成体系 ,博大精深 ,亟待发掘整理。幽默在中国本土共名应是“雅谑” ,其形态包括达生、幽雅、雅谑、绝倒、诞妄等。     

Discovering classes in microarray data using island counts

We present a new biclustering algorithm to simultaneously discover tissue classes and identify a set of genes that well-characterize these classes from DNA microarray data sets. We employ a combinatorial optimization approach where the object is to simultaneously identify an interesting set of genes and a partition of the array samples that optimizes a certain score based on a novel color island statistic. While this optimization problem is NP-complete in general, we are effectively able to solve problems of interest to optimality using a branch-and-bound algorithm. We have tested the algorithm on a 30 sample Cutaneous T-cell Lymphoma data set; it was able to almost perfectly discriminate short-term survivors from long-term survivors and normal controls. Another useful feature of our method is that can easily handle missing expression data.     

An efficient polynomial space and polynomial delay algorithm for enumeration of maximal motifs in a sequence

In this paper, we consider the problem of enumerating all maximal motifs in an input string for the class of repeated motifs with wild cards. A maximal motif is such a representative motif that is not properly contained in any larger motifs with the same location lists. Although the enumeration problem for maximal motifs with wild cards has been studied in Parida et al. (2001), Pisanti et al. (2003) and Pelfrêne et al. (2003), its output-polynomial time computability has been still open. The main result of this paper is a polynomial space polynomial delay algorithm for the maximal motif enumeration problem for the repeated motifs with wild cards. This algorithm enumerates all maximal motifs in an input string of length n in O(n ³) time per motif with O(n) space, in particular O(n ³) delay. The key of the algorithm is depth-first search on a tree-shaped search route over all maximal motifs based on a technique called prefix-preserving closure extension. We also show an exponential lower bound and a succinctness result on the number of maximal motifs, which indicate the limit of a straightforward approach. The results of the computational experiments show that our algorithm can be applicable to huge string data such as genome data in practice, and does not take large additional computational cost compared to usual frequent motif mining algorithms. This work is done during the Hiroki Arimura’s visit in LIRIS, University Claude-Bernard Lyon 1, France.     

Theorizing in Family Studies: Discovering Process

This paper makes the case that theorizing in family studies might be different if scholars asked the types of questions that now are asked in the physical sciences. Initial efforts to move toward a more abstract explanatory level in family studies led to inventorying and verification. This paper argues that the recognition of a realm of discovery, allowing for the creative and disciplinary use of imagination and metaphor, would extend the scope and quality of questioning. To ground the argument, the paper focuses on the problematics associated with the conceptualization of process in marriages and families.
