神话的不完美崇拜

神话以其隐喻的方式告诉我们，天地乃至生命之不完美是好奇的人类自己的选择。因为只有经由这种不完美崇拜，人才可能胸怀理想、探求未知、找寻真理、认识自我。与生命意义和自我价值的找寻息息相关，这是神话自古至今一直具有震撼人心的魅力并始终为人们所需要的原因所在。     

中国古代易代小说类型论略

从题材与主题考察,我国古代长篇章回历史小说最初最根本的类别是易代小说。易代小说就是以易代之际为主要叙事时间,以主宰王朝兴亡的历史人物为描写对象,以易代"兴废争战之事"为主要内容,以兴衰为叙事线索与情节模式,有着强烈兴亡之感、易代之思的历史小说。易代小说有着悠久的历史文学渊源,明清两朝现存的易代小说共33部。易代小说蕴藉着丰富的文化内涵,对国人影响极其深远。对易代小说这一类型进行专门研究能揭示我国历史小说的本质问题,将历史小说的研究引向深入,为历史小说和易代问题的研究提供一个新视角。     

MFN tariff treatment of imports from China: Effects on U.S. employment

This article estimates the effects on U.S. output and employment of granting most-favored-nation (MFN) tariff treatment to imports from the People's Republic of China (PRC). Import demand elasticities are used to estimate changes in imports resulting from the lower tariff rates. A highly disaggregated U.S. input-output table and labor-output ratios are used to convert changes in imports into changes in domestic output and employment at a detailed sectorial level. U.S. import restraints on the textile and apparel industry are incorporated into the analysis. The article explores the implications of increased imports from the PRC for U.S., PRC, and LDC policy makers.     

The nexus between income distribution,trade policy,and monopoly power: An assessment of the tin market

The article suggests a manner in which degrees of monopoly power can be introduced into a trade policy model of the computable general equilibrium type. The distributional effects of tariffs and subsidies are compared, first under competitive conditions and then under conditions of monopoly power.The tin market, for which Malaysia can be assumed to exert monopoly power, is used as an example to show the distributional consequences of applying a competitive model in cases where a model allowing for monopoly power would have been more appropriate. The existence of monopoly power is shown to have important distributional effects. Policy modelers, dealing with distributional issues, should therefore be careful about the assumptions made about market forms.     

Order statistics from non-identical right-truncated Lomax random variables with applications

In this paper, we derive some recurrence relations for the single and the product moments of order statistics from n independent and non-identically distributed Lomax and right-truncated Lomax random variables. These recurrence relations are simple in nature and could be used systematically in order to compute all the single and product moments of all order statistics in a simple recursive manner. The results for order statistics from the multiple-outlier model (with a slippage of p observations) are deduced as special cases. We then apply these results by examining the robustness of censored BLUE's to the presence of multiple outliers. Received: November 30, 1998; revised version: March 8, 2000     

国有企业改制中国有资产流失的原因分析及法律对策

国企改制中的国有资产流失可分为两个阶段 ,一是在改制过程中由于低估、折股造成的损失 ,二是在改制后国有股运营中造成的利益损失。流失的主要原因是没有健全国有资产监管体制 ,资产评估不依法规范进行以及国有股不能上市流通。遏制国有资产流失主要在于尽快完善国有资产运管体制 ,严格规范资产评估行为 ,尽快实现国有股上市流通     

Semiparametric median residual life model and inference

For randomly censored data, the authors propose a general class of semiparametric median residual life models. They incorporate covariates in a generalized linear form while leaving the baseline median residual life function completely unspecified. Despite the non‐identifiability of the survival function for a given median residual life function, a simple and natural procedure is proposed to estimate the regression parameters and the baseline median residual life function. The authors derive the asymptotic properties for the estimators, and demonstrate the numerical performance of the proposed method through simulation studies. The median residual life model can be easily generalized to model other quantiles, and the estimation method can also be applied to the mean residual life model.

Unaliasing of aliased line component frequencies

This paper is concerned with undoing aliasing effects, which arise from discretely sampling a continuous‐time stochastic process. Such effects are manifested in the frequency‐domain relationships between the sampled and original processes. The authors describe a general technique to undo aliasing effects, given two processes, one being a time‐delayed version of the other. The technique is based on the observations that certain phase information between the two processes is unaffected by sampling, is completely determined by the (known) time delay, and contains sufficient information to undo aliasing effects. The authors illustrate their technique with a simulation example. The theoretical model is motivated by the helioseismological problem of determining modes of solar pressure waves. The authors apply their technique to solar radio data, and conclude that certain low‐frequency modes known in the helioseismology literature are likely the result of aliasing effects.
