虚拟社区中知识交流的特点分析——基于CSDN技术论坛的实证研究

以国内著名的技术网络论坛CSDN为研究实例,从中抽取出知识交流网络,采用复杂网络的分析方法进行分析,试图定量化地揭示虚拟社区中知识交流的特点。论文一方面分析知识交流网络的基本统计量,指出它具备无标度性质和小世界效应,并对其成因进行分析;另一方面通过分析知识交流网络中的“用户三角形”,揭示了虚拟社区中知识传播的两种基本图式。     

复杂网络统计参量对病毒传播速率的影响

复杂网络统计参量是描述复杂网络结构的普适参量,病毒的传播与这些基本参量密切相关,病毒传播速率与复杂网络统计参量间存在确定的联系。文章推论了复杂网络中病毒传播速率与基本网络参量的函数关系。利用这一函数可以在已知的网络结构参数时,得到病毒传播的预测值。     

梦中来复少年身：谈金庸短篇小说《月云》

金庸2000年发表的短篇小说《月云》,是一篇自传色彩很浓的作品。男主人公童年宜官真诚对待弱小者丫环月云,并对她产生＂主人——婢女＂模式的朦胧情愫,整个作品流露出忆念江南的＂江南情结＂,都可以看成是金庸后来创作的武侠小说中倡导平等博爱思想、描写＂一男多女＂式情感关系、对江南和其他地域的描写笔法各异的源头。作者通过追忆童年经历,实际上为自己的武侠小说创作和人生道路做出了某种自我诠释,这篇小说是透视金庸其人及其作品的一扇窗口。     

从爱欲的反动到救赎的探寻——浅析约翰·厄普代克小说中的“欲望”情结

美国当代著名作家约翰·厄普代克认为爱欲是一种原始生命力,并把这种生命力寓于艺术中让其成为创作的动力与命脉。本文从厄普代克小说中主题入手,揭示了其潜在的欲望情结,并借此开始了对生命的扣问。     

特厚、突出、极松软、大应力、极复杂地质条件下跟煤底施工技术研究

青东矿82采区8煤层首采工作面为828工作面,煤层厚度6.2～13.2m,平均厚度为9.2m,回采工艺为综放,工作面巷道施工采取跟底留顶煤施工,由于煤体松散破碎,同时过上覆726工作面收作线应力集中区、频繁过断层、过构造,在施工期间遇到很多了困难,特别是极松散的煤顶在超前管理上、支护上,和现场施工管理上采取非常有价值的举措,成功的克服了各种困难,巷道单进达100m/月,减少了工作面准备时间,回提前回采产出的煤炭而带来巨大的经济效益和社会效益。     

Effects of agonist–antagonist complex resistance training on upper body strength and power development

Abstract

The objective of this study was to examine the chronic effects on strength and power of performing complex versus traditional set training over eight weeks. Fifteen trained males were assessed for throw height, peak velocity, and peak power in the bench press throw and one-repetition maximum (1-RM) in the bench press and bench pull exercises, before and after the eight-week programme. The traditional set group performed the pulling before the pushing exercise sets, whereas the complex set group alternated pulling and pushing sets. The complex set training sessions were completed in approximately half the time. Electromyographic (EMG) activity was monitored during both test sessions in an attempt to determine if it was affected as a result of the training programme. Although there were no differences in the dependent variables between the two conditions, bench pull and bench press 1-RM increased significantly under the complex set condition and peak power increased significantly under the traditional set condition. Effect size statistics suggested that the complex set was more time-efficient than the traditional set condition with respect to development of 1-RM bench pull and bench press, peak velocity and peak power. The EMG activity was not affected. Complex set training would appear to be an effective method of exercise with respect to efficiency and strength development.

Male/Female Relationships in Strange Interlude

Strange Interlude has been considered the most complicated play ever written by Eugene O'Neill,not only because of it's great length,but also because of the complex in structure.The play conversal most the entire life of a woman,right from her girlhood to old age.This paper intends to analyze diverse male/fem ale relationships that are evident in thisplay.
