试论实践教学质量监控的主要途径

实践教学是与理论教学紧密联系又相对独立的一种教学环节。在高校人才培养中起着理论教学不可替代的作用。受重理论轻实践的传统教育观念的影响，实践教学质量监控还存在着一些问题。该文结合学校实践教学管理实践。从四个方面阐述了加强实践教学质量监控的主要途径。     

What was classical genetics?

I present an account of classical genetics to challenge theory-biased approaches in the philosophy of science. Philosophers typically assume that scientific knowledge is ultimately structured by explanatory reasoning and that research programs in well-established sciences are organized around efforts to fill out a central theory and extend its explanatory range. In the case of classical genetics, philosophers assume that the knowledge was structured by T. H. Morgan’s theory of transmission and that research throughout the later 1920s, 30s, and 40s was organized around efforts to further validate, develop, and extend this theory. I show that classical genetics was structured by an integration of explanatory reasoning (associated with the transmission theory) and investigative strategies (such as the ‘genetic approach’). The investigative strategies, which have been overlooked in historical and philosophical accounts, were as important as the so-called laws of Mendelian genetics. By the later 1920s, geneticists of the Morgan school were no longer organizing research around the goal of explaining inheritance patterns; rather, they were using genetics to investigate a range of biological phenomena that extended well beyond the explanatory domain of transmission theories. Theory-biased approaches in history and philosophy of science fail to reveal the overall structure of scientific knowledge and obscure the way it functions.     

论"新红学"的知识谱系

“新红学”的基本构成是“实证与实录合一”．胡适以“科学精神”演述乾嘉学术方法,以“自然主义”、“自叙传”去演述传统的史学实录观念．实证研究体现一种科学精神,实录观念则是一种反科学的观念．     

后殖民语境中的翻译“逆差”及对策

在跨文化交流中,由于文化的输入和输出的不平衡,从而导致翻译上的“逆差”。运用后殖民主 义理论分析“逆差”产生的原因,并提出对策。     

Internet网上汉字与图形E-mail的解读、编存与传送

分析了用Internet传送汉字与图形E-mail时的"乱码"问题.介绍了汉字与图形电子邮件的解读、编写、存储及传送的方法.     

一类非线性系统的多故障检测方法研究

针对一类非线性系统,提出了一种基于最优滤波的多故障检测观测器设计方法。引入神经网络逼近系统非线性部分,由Lyapunov稳定性理论设计神经网络权值调整规则.采用对等空间方法设计最优滤波矩阵滤除干扰故障噪声,从而对目标故障进行检测和跟踪。仿真结果验证了该方法的正确性和可行性。     

超生产容量阻止对手进入有效性的实物期权分析

将产业中企业竞争的策略行为推广到不确定性的市场环境中,用实物期权分析方法研究了行业内的垄断企业阻止具有决策灵活性的潜在进入者时,投资超生产容量策略的有效性.研究基于行业内企业的生产容量对进入者项目价值的影响评估,给出了业内企业生产容量对对手的进入期权价值和投资决策的影响结果,证明了当潜在进入者有足够的决策灵活性:投资前持有进入期权,投资后持有暂时停止和恢复期权时,对业内企业设置的任何生产容量,潜在进入者都会等待有限的时间后投资进入行业,即在净现值分析方法下有效的、以超生产容量阻止进入的竞争策略,对于持有投资和生产决策期权的进入者是无效的.     

开展党建工作的新思路

探讨了21世纪的党建工作,提出了开展党建工作的新思路:突出新时代的特点和先进性;强化创新意识;按照党建目标,提高党员队伍整体素质;通过互联网建立大党建"网络社会"。     

"软件质量保证与测试"授课经验分享

Based on teaching experiences accumulated from past 5 years author shares the teaching process and approaches on course of "Software Quality Assurance and Testing",which includes course syllabus,teaching approaches,and evaluation methods,etc.We hope that this paper would have a positive input to those who are in the process of teaching software engineering related courses as well as to those who are in the process of teaching practice-oriented bilingual courses.     

对不平衡类分类的一种组合方法

具有不平衡类分布的数据集在许多实际应用中是很常见的,但由于类分布不平衡,给那些已有的分类算法带来了很多问题。一种为处理不平衡类问题而开发的基于决策树和人工神经网络的有效组合方法被讨论。它基于数据抽样的方法构建组合分类器,并利用ROC曲线(Receiver Operating Characteristic curve)作为评价挖掘性能的分析工具,最后在PAKDD2007竞赛活动提供的实际数据上进行了有效性验证。
