Prediction of the residual failure processes based on the process history

In the reliability area, the concept of the residual lifetime of a non repairable system is very important and its property has been intensively studied. In this article, we define the “residual failure process” for a repairable system and study its stochastic properties thoroughly. The detailed discussions are given when the corresponding failure process is a renewal process. An illustrative example is also discussed.     

长三角地区城市化健康发展问题的观察与思考

本文研究首先从人口总量、人口分布以及城镇化格局变动三个方面分析了长三角地区的城市化发展现状。其次剖析了人口、资源、环境协调发展问题,区域中心城市培育问题,浅度城市化问题,以及城市社区管理转型问题。最后就城市群整体实力提升、城市间协作分工以及城市社区管理提升等三方面提出对策建议。     

英语世界的托•斯•艾略特反犹主义研究

英语世界对托?斯?艾略特反犹主义的研究可以追溯至１９３０年代中期,但从１９８０年代开始,艾略特反犹主义问题才逐渐成为学术界关注的焦点。１９９０年代末,学界围绕艾略特的反犹主义问题进行了较大范围、较长时间、较为激烈的争论。２０００至２０１０年代,研究持续推进,成果频出。阿克罗伊德、威尔克、里克斯、夏普、朱利叶斯、阿什尔等人的著作和珀金斯、弗莱斯纳、施密特、斯科特、雷恩、斯蒂文斯等人的文章从艾略特的言论、书信、诗歌、文章等着手?对艾略特的反犹主义问题进行研究,拓宽了英语世界艾略特研究的领域。     

面对全球化挑战的知识分子

全球化具有不同的层面,这些层面之间是相互影响、相互作用,甚至是相互冲突的,例如经济的全球化与社会正义的全球化。因此,对全球化进行单纯的批评和支持是没有意义的,只有理性的分析才能阐释多元全球化。在此意义上,知识分子应担负起我们时代自我理解的重要使命。     

一种信道中预去相关CDMA系统的性能

考虑预去相关发射技术的同步码分多址通信系统，在非选择性Ｒｉｃｉａｎ衰落并受加性白高斯噪声扰动影响的信道中的比特差错概率性能。结果表明，由于衰落的影响使得比特差错概率增加了；比特差错概率随非直通信号幅度的增加而增加

复杂理论:二语习得研究的新视角

二语习得/发展可以被看成异质的、动态变化的、非线性的、自适应的、开放的复杂系统,系统中各要素交互作用引起了二语习得发展的变化。"复杂理论"就是对系统中各要素的变化、要素间交互作用的变化、系统轨迹的变化及系统与其它系统的关系进行描述、解释和预测。在复杂理论的新视角下,二语习得领域中值得探索的方向包括语法中的"怪现象"、二语能力的测试、二语习得系统的建模、二语发展轨迹的个体内差异研究、方法论研究等。     

Ethical values and social change: Mahatma Gandhi,Martin Luther King,Jr. and Ahn Chang Ho

Mahatma Gandhi, Martin Luther King, Jr. and Ahn Chang Ho exemplify the leaders who brought social change by applying their belief in non-violence and love of humanity to the accomplishment of their respective goals. Gandhi’s goal was securing India’s independence from British colonialism, and King’s was to rid America from racial segregation. Irony about England and the US was that they had a long history of commitment to human rights and democracy. Hence, Gandhi and King’s struggle for justice focused on reminding their adversaries of their hypocrisy, a gulf between their commitment and actions. Ahn had to deal with Japanese colonialists, who had little respect for and commitment to human rights and civil liberties. Ahn’s job was, therefore, more complicated than Gandhi’s or King’s. Ahn insisted that for the Koreans to achieve their political independence from Japan, they must build their inner strength first, and do this by self-cultivation of moral and ethical values. Building moral and ethical strength ought to also accompany receiving modern education, acquiring marketable skills, and building financial resources. At the same time he condoned the militant approach to the Korean independence movement, as necessary. Ahn was a complex figure, a blend of a moralist, a strategist, and a pragmatist.
