中国古代城市文学研究的文学史意义

研究中国古代城市文学的文学史意义在于，从空间视角重新认识和研究古代文学，充分发掘和利用长期以来被忽略的城市文学资源。有助于建构起时空并置、更加完整和系统的中国古代文学史。此外，研究中国古代城市文学还可以为当代文学史研究提供一个广阔的历史视野与意蕴深厚的历史文本。     

论盛唐声诗和绝句为唐曲词发生的前夜

盛唐延续了初唐的去音乐化运动，古风中的乐府和歌行盛行，造成了音乐消费的空缺，以七言绝句为代表的声诗大量涌现以满足对声乐歌词的需求，这种现象一直延续到中唐时代，直到词体形式的代兴，才渐次出现了词体取代声诗的现象，因此，盛唐绝句声诗的兴盛可以看作词体发生的前夜。     

神性、人性和理性--略论艺术形态与时代精神

艺术的本质在于其精神性,从艺术和时代精神的相互关系中去确立划分艺术形态的标准是符合艺术本质的.按照艺术所包含的精神内容的不同,艺术形态可分为神性艺术、人性艺术和理性艺术,以丰富的艺术史例可以说明其特征.     

大学研究院管理体制与运行机制创新研究

创新大学研究院管理体制和运行机制，对于推动大学知识和科技创新、加速科技成果产业化和社会化具有重要作用。为此，大学研究院在管理体制方面要实行理事会领导下的院长负责制和虚实结合的矩阵式组织模式。在运行机制方面应建立稳定有力的政策支持体系和科学民主的战略决策制度，建立以团队合作为主的科研队伍体系，建立以竞争为核心的人员聘用体系，建立科学的业绩考评和高效的人才激励制度，建立长效完备的投资渠道，建立积极有效的成果转化机制。

An empirical investigation of the box-cox model and a nonlinear least squares alternative

In this paper we present a generalized functional form estimator, recently developed by jeffrey Wooldridge; and then we compare it empirically to the popular Box-Cox (BC) estimator using three data sets. We begin by briefly reviewing the drawbacks of the BC estimator. We Then introduce the nonlinear lest squares (NLS) alternative of Wooldridge which retains the desirable qualities of the BC estimator without the associated theoretical problems. We continue by applying both the BC and the NLS models to data from three classic hedonic regression studies and then compare the estimation resuts-point estimates, inferences and fitted values. The estimations include a wage rate equation, and two computer hedonic regression equations, one using data from a classic study by Gregory Chow and the other using an IBM data set that formed the basis of the new official BLS computer price index.     

Normalized Quadratic Systems of Consumer Demand Functions

Empirically estimated demand systems frequently fail to satisfy the appropriate theoretical curvature conditions. We propose and estimate two demand systems for which these conditions can be imposed globally; the first is derived from a normalized quadratic reciprocal indirect utility function and the second is derived from a normalized quadratic expenditure function. The former is flexible if there are no restrictions on its free parameters, but loses flexibility if the curvature conditions need to be imposed. The latter is flexible, in the class of functions satisfying local money metric scaling, even if the curvature conditions need to be imposed.     

The numerical evaluation of the distribution function of a bilinear from to a quadratic from with econometric examples

This paper considers a general and computationally convenient method of evaluating the distribution function of statistics that are the ratio of a bilinear form to a quadratic form. Numerous Economemc applications of the method are given.     

Random sampling from the watson distribution

An envelope-rejection method is used to generate random variates from the Watson distribution. The method is compact and is competitive with, if not superior to, the existing sampling algorithms. For the girdle form of the Watson distribution, a faster algorithm is proposed. As a result, Johnson's sampling algorithm for the Bingham distribution is improved.
