“说炜烨而谲诳”——论刘勰对陆机《文赋》的一个错误批评

战国时期产生了一种生动活泼的口头文体形式——说,其文体寓说理于叙事之中,具有形象性、传奇性和虚构性等特点。它是中国后世小说创作的重要来源之一。陆机在《文赋》中明确把说定为一种文体,并用炜烨与谲诳来概括它。所谓炜烨,即生动性和形象性;谲诳,即传奇性和虚构性。陆机对这些特征的肯定,正与魏晋时期文学创作意识尤其是小说创作的兴盛有密切关联。而刘勰在《文心雕龙》中,以正统儒家的义贞和忠信为法斧,对陆机的命题进行了歪曲的否定。刘勰对陆机的这一粗暴悖理的批评,反映了他正统的儒家意识以及否定小说创作的保守的文学立场。事实上,陆机的说炜烨而谲诳,在中国小说批评史上占有重要位置,而《文心雕龙》也并非绝对完满、完全公正的超越性体系,它也存在自己的局限和谬误。     

存在交易成本的间断性权证避险策略研究

随着金融创新步伐加快,券商将可以发行备兑权证.券商如何进行避险操作来规避风险呢?若按照Black&Scholes理论进行动态连续避险操作,将造成巨大的交易成本.因此,实际中都是采用间断性避险.文章对间断性避险策略进行初步研究.根据限制交易成本的不同方式,主要探讨了三类存在交易成本时的间断性避险策略:固定时点避险策略,区间避险策略以及以效用函数为基础的避险策略,并比较了不同策略的避险效果.最后结合中国市场具体情况研究了不同监管制度对权证避险策略选择的影响.     

重估现代女作家的出现——以新文学期刊(1917-1925)中的女作者创作为视点

"五四"新文化运动中,进入学堂学习的女学生迅速成为了新文学杂志的重要作者,在女作家成长的过程中,新文学期刊及其主办者、编辑者的帮助和扶持起了十分重要的作用。女作者们借助现代出版的平台走向社会,走向读者,以集体的方式浮出历史地表,成为中国现代文学史上的第一代女作家。     

Portmanteau test for conditional heteroscedasticity, using ranks of squared residuals

Squared residual autocorrelations have been found useful in detecting departures from linearity in time series models. This is especially the case with data exhibiting heterogeneity in variances. A rank test is proposed which is much more robust than its parametric counterpart.

“数字鸿沟”：当代社会阶层分析的新视角*

当代社会，随着信息技术的发展以及信息重要性的增强，以互联网等为基础的电子信息网络已经浸透于社会的各个领域之中，在产业、经济和社会中生成着一种新的信息场域，影响着人们的社会生活。本文从社会阶层的研究视角出发，透过“现代——后现代”的二维分析模式对信息及信息技术带来的“数字鸿沟”现象进行理论上的阐释，对其究竟是实现着“阶层化”还是“去阶层化”进行探讨，并对信息化高度发达的日本社会进行了“数字鸿沟”的实证分析。可以看出：信息、信息技术已经成为一种新的变量，并与社会阶层之间产生着密切的关系，重塑着社会阶层化机制。     

振兴辽宁交通先行

交通运输是重要的基础产业,是辽宁振兴的先导和保障。“十五”期间,辽宁省委、省政府对高速公路建设给予了高度重视,省委书记李克强指出:交通运输是重要的基础性和先导性产业。实现辽宁全面振兴,必须发挥交通事业的关键作用。城市交通体系四通八达“十五”期间,辽宁省新增城市道路面积2263万平方米;新增公交车辆7317标台;在城市人口增长的情况下,万人拥有公交车辆9标台,比“九五”期末增加0.55标台。而对于越来越多的人来说,拥有一辆自己的汽车成了越来越迫切的愿望。随着经济的发展,5年间辽宁省全年城镇居民人均可支配收入已由5357.8元提高…     

A cultural economy perspective on service sector migration in the global city: the case of Hong Kong

This article argues that in order to fully understand the geography of labour migration to global cities, it is necessary to consider economic forces in conjunction with mediating socio-cultural influences. Support for this argument is based on an examination of the pattern of migration to Hong Kong, a city which plays a significant role in the world economy.
Reported here are the results of an analysis of recently released 1996 by-census data, and the authors' interviews with foreign domestic workers in Hong Kong. These findings have shown that highly skilled immigrant workers were drawn largely from developed countries, the main sources of inward investment in this city, while less skilled immigrants were drawn from less developed neighbouring labour markets.
While the geographical pattern of immigration followed broadly that predicted from Hong Kong's position in the world economy, the results have revealed that cultural influences such as language and social networks are also important in shaping the economic roles of migrant workers.     

Stability of voting games

This paper generalizes the result of Le Breton and Salles (1990) about stable set (far-sighted core of order 1) for voting games to far-sighted core of arbitrary order. Let m be the number of alternatives, n be the number of voters and G(n,k) be a proper symmetric simple game in which the size of a winning coalition is greater or equal to k. It is shown that the far-sighted core of order d for G(n,k) is nonempty for all preference profiles and for all n and k with n/(n–k)=v ¹ iff m(d+1)(v–1).This paper is part of my dissertation. I am grateful to my thesis advisor Leonid Hurwicz for his guidance and encouragement. I would like to thank Edward Green, Lu Hong, James Jordan, Andrew McLennan, Herve Moulin and Marcel Richter for their very helpful suggestions. Especially a referee and Maurice Salles made many good comments. Of course, any errors that remain are the sole responsibility of the author.
