"三个代表":必须长期坚持的指导思想

中共十六大把"三个代表"重要思想作为党必须长期坚持的指导思想写入党章,是党的理论创新和实践发展的必然要求,完全符合马克思主义思想路线的根本要求,体现了党的指导思想的与时俱进,为在新世纪全面建设小康社会,加快推进社会主义现代化,提供了强大的理论武器.贯彻中共十六大精神,必须坚定不移地坚持和贯彻"三个代表"重要思想.     

试析柏拉图对“知识合法性”的逻辑论证

在讨论世界的本原和逻辑起点问题上,自然哲学家的观点表明,他们实际上走的是从经验到一般的认识路线.而柏拉图则是从一般到事实,通过"理念论",论证了知识普遍必然性和客观有效性的客观依据,解决了"知识何以可能"的逻辑前提.     

儒家"修齐治平"的人生理想与当代中国企业家的成长

儒家文化是中国传统文化的主流,其积极主张"入世"的人生态度和追求"修齐治平"的人生理想,为历代君王、臣僚、士大夫等阶层所信奉和追求;西汉以降及至明清,中国商人一直不能作为一个独立的社会阶层来追求和实践其"修齐治平"的人生理想,少有影响社会历史进程的商家;在市场经济体制已经确立的当今中国,将"修齐治平"的人生理想作时代诠释,对促进中国企业家的成长,具有现实意义.     

论金大中政府关于朝鲜半岛和平机制的构想

为实现朝鲜半岛的长期稳定与持久和平,金大中总统上台后开始构建新的半岛和平机制,其主要政策和措施有三个方面一是通过巩固韩美军事同盟关系等措施加强军事实力,以此作为构建半岛和平机制的基础和后盾;二是改善对朝关系,实施以"阳光政策"为主要内容的对朝柔和政策,以此作为构建半岛和平机制的主要策略;三是加强周边"四强协调外交",密切与其关系,以此作为构建半岛和平机制的外部推动和制约力量.     

交际意识是外语教学交际法的灵魂

交际法时下似乎已不怎么"奏效”,对其认识上误区不少,做法上许多已远离初衷.本文从培养学生的交际能力为外语教学的主要目的出发,阐明了交际思想的由来与实质,论述了交际思想两大支柱理论交际能力和学生中心思想.交际思想具有丰富的内涵.交际法不是一种具体的教学方法,而是一种思想观念.要真正有效地实施交际法,必须从转变观念入手,培养和树立各种交际意识.     

Distance graphs on R n with 1-norm

Suppose S is a subset of a metric space X with metric d. For each subset D⊆{d(x,y):x,y∈S,x≠y}, the distance graph G(S,D) is the graph with vertex set S and edge set E(S,D)={xy:x,y∈S,d(x,y)∈D}. The current paper studies distance graphs on the n-space R ₁ ⁿ with 1-norm. In particular, most attention is paid to the subset Z ₁ ⁿ of all lattice points of R ₁ ⁿ . The results obtained include the degrees of vertices, components, and chromatic numbers of these graphs. Dedicated to Professor Frank K. Hwang on the occasion of his 65th birthday.

Establishing decision tree-based short-term default credit risk assessment models

ABSTRACT

Traditional credit risk assessment models do not consider the time factor; they only think of whether a customer will default, but not the when to default. The result cannot provide a manager to make the profit-maximum decision. Actually, even if a customer defaults, the financial institution still can gain profit in some conditions. Nowadays, most research applied the Cox proportional hazards model into their credit scoring models, predicting the time when a customer is most likely to default, to solve the credit risk assessment problem. However, in order to fully utilize the fully dynamic capability of the Cox proportional hazards model, time-varying macroeconomic variables are required which involve more advanced data collection. Since short-term default cases are the ones that bring a great loss for a financial institution, instead of predicting when a loan will default, a loan manager is more interested in identifying those applications which may default within a short period of time when approving loan applications. This paper proposes a decision tree-based short-term default credit risk assessment model to assess the credit risk. The goal is to use the decision tree to filter the short-term default to produce a highly accurate model that could distinguish default lending. This paper integrates bootstrap aggregating (Bagging) with a synthetic minority over-sampling technique (SMOTE) into the credit risk model to improve the decision tree stability and its performance on unbalanced data. Finally, a real case of small and medium enterprise loan data that has been drawn from a local financial institution located in Taiwan is presented to further illustrate the proposed approach. After comparing the result that was obtained from the proposed approach with the logistic regression and Cox proportional hazards models, it was found that the classifying recall rate and precision rate of the proposed model was obviously superior to the logistic regression and Cox proportional hazards models.     

饲料中食盐快速测定法与标准法的对比试验

本试验采用国标法（GB6439-86）及快速测定法来测定饲料和单一饲料中氯化物的含量。结果表明：快速法测值普遍比标准法高，并且饲料中盐分含量越高，两值越接近。快速法操作简便，两个平行样的偏差较小；标准法操作烦琐，操作本身又易使结果偏低。故快速法在生产中应用具有一定意义。
