关于经济学数学化问题的探讨

目前 ,经济学数学化趋势十分明显。但这种应用也产生了所谓的“工具理性”和“科学主义”的问题 ,并有使数学方法牵强附会和盲目扩大的倾向。尽管如此 ,数学方法在经济学的研究中仍具有相当的重要性

文化力:综合国力竞争的重要内容和强大精神动力

十六大关于文化建设和文化体制改革的论述高度重视文化力和精神力在综合国力竞争中的地位和作用,具有重大意义。文化力的系统构成包括文化创新生产能力、对人民的文化聚合能力、文化产品生产者和消费者的综合素质和精神状态("士气战斗力")、对外部文化的影响力。文化的力量,深深熔铸于民族的生命力、创造力和凝聚力之中。     

尼采道德哲学的现代阐释

尼采的道德哲学并不是一般意义上的道德哲学或者伦理学,它是一种本体意义上的生命意义哲学。尼采整个道德哲学的出发点和目的,便是为生命赋予意义,他是站在生命立场上否定旧的道德价值,而又站在生命立场上呼唤新的道德价值。这样一种以生命意义为核心的道德哲学,剥离了道德价值对生命价值的"遮蔽",生命价值获得了"澄明"和"敞亮",确定了生命价值的一阶地位。这一思路对现代哲学,尤其是存在主义哲学以极大的启发。     

藤野:鲁迅前期内心世界中的一个亮点--在日本芦原町"藤野严九郎与鲁迅"专题研讨会上的发言

鲁迅对藤野先生的感激之情何以非同寻常?首先是自“家庭变故”后,鲁迅一直在寻找“别样的人们”,从南京、东京,至仙台,鲁迅终于发现了“伟大的”“性格”;其次,写作《朝花夕拾》时的鲁迅,因生活中颇多“纷扰”而希望“在纷扰中寻出一点闲静来”,鲁迅正是借回忆藤野先生而在自我生命的底蕴里,寻找光明的力量。     

Fast On-Line/Off-Line Algorithms for Optimal Reinforcement of a Network and its Connections with Principal Partition

The problem of computing the strength and performing optimal reinforcement for an edge-weighted graph G(V, E, w) is well-studied. In this paper, we present fast (sequential linear time and parallel logarithmic time) on-line algorithms for optimally reinforcing the graph when the reinforcement material is available continuously on-line. These are the first on-line algorithms for this problem. We invest O(|V|³|E|log|V|) time (equivalent to (|V|) invocations of the fastest known algorithms for optimal reinforcement) in preprocessing the graph before the start of our algorithms. It is shown that the output of our on-line algorithms is as good as that of the off-line algorithms. Thus our algorithms are better than the fastest off-line algorithms in situations when a sequence of more than (|V|) reinforcement problems need to be solved. The key idea is to make use of ideas underlying the theory of Principal Partition of a Graph. Our ideas are easily generalized to the general setting of polymatroid functions. We also present a new efficient algorithm for computation of the Principal Sequence of a graph.     

A formulation of the concept of probability based on the use of experimental devices

This paper sets out to identify the abilities that a person needs to be able to successfully use an experimental device, such as a probability wheel or balls in an urn, for the elicitation of subjective probabilities. It is assumed that the successful use of the device requires that the person elicits unique probability values that obey the standard probability laws. This leads to a definition of probability based on the idea of the similarity between the likeliness of events and this concept is naturally extended to the idea that probabilities have strengths, which relates to information about the likeliness of an event that lies beyond a simple probability value. The latter notion is applied to the problem of explaining the Ellsberg paradox. To avoid the definition of probability being circular, probabilities are defined such that they depend on the choice of a reference set of events R which, in simple cases, corresponds to the raw outcomes produced by using an experimental device. However, it is shown that even when the events in R are considered as having an “equal chance” of occurring, the values and/or strengths of probabilities can still be affected by the choice of the set R.

劣势侧下肢离心训练对肌肉力量的影响研究

为了研究离心训练对劣势侧下肢肌肉力量的影响情况,通过对20名受试者进行为期6周的劣势侧下肢的等速离心训练实验,结果发现,训练组屈伸肌群实验后在最大力矩与总功方面均有显著增加;训练组和对照组劣势侧屈伸肌群最大力矩与总功均呈现出60°/s>120°/s>180°/s的趋势;踝关节屈伸肌进行离心训练后伸肌肌力增长的更快.这为进一步深入研究离心训练对肌肉力量的影响提供了理论参考依据.     

基于RiskMetrics模型的单个期货合约保证金比例设计

为了规避价格波动风险,期货交易所应该采取动态保证金设置方式。本文对单个期货合约的日收益序列建立了基于RiskMetrics的VaR模型,用滚动样本预测下一交易日的VaR值,而LR检验表明所建立的VaR模型能较好地测度价格波动风险。因此,下一交易日保证金比例可以设置为预测的VaR值和所规定的涨跌停板率的最小值,这样就能以相应的概率抵御该交易日价格波动带来的风险。
