金初耆旧作家与庾信之比较

同为出仕北方少数民族政权的汉族作家,由南朝入北朝的庾信和由宋入金的耆旧作家的作品却有很大的不同。金初耆旧作家缺乏庾信作品中的王室情,其各自的具体处境和历史环境是其主要原因。     

文化批评的意义与局限

文化批评的兴起有多方面的原因,其存在的合理性与现实价值显而易见。但是,作为一种批评方法,文化批评不过是为文学批评打开了一个新的窗口;而任何窗口都是有局限的,文化批评也必然会遮蔽一些东西。当下流行的文化批评因审美尺度的缺席而走向非文学化,并导致批评与创作的亲缘关系的解体。因此,文化批评的自我检讨已势在必行。     

An empirical likelihood goodness-of-fit test for time series

Summary. Standard goodness-of-fit tests for a parametric regression model against a series of nonparametric alternatives are based on residuals arising from a fitted model. When a parametric regression model is compared with a nonparametric model, goodness-of-fit testing can be naturally approached by evaluating the likelihood of the parametric model within a nonparametric framework. We employ the empirical likelihood for an α -mixing process to formulate a test statistic that measures the goodness of fit of a parametric regression model. The technique is based on a comparison with kernel smoothing estimators. The empirical likelihood formulation of the test has two attractive features. One is its automatic consideration of the variation that is associated with the nonparametric fit due to empirical likelihood's ability to Studentize internally. The other is that the asymptotic distribution of the test statistic is free of unknown parameters, avoiding plug-in estimation. We apply the test to a discretized diffusion model which has recently been considered in financial market analysis.

利用光敏核不育性进行水稻轮回选择的程序探讨

本文对利用光敏核不育性进行水稻轮回选择进行了探讨。提出基本轮回选择方案和综合轮回选择方案。基本轮回选择方案是以一个光敏核不育材料为母本与多个亲本组配构成轮回选择的综合群体,而其后按常规轮回选择法进行育种的方案。综合轮回选择方案是以两个或两个以上的光敏核不育材料作为母体与多个亲本组配,在 F_2代群体中不同质源的优良植株相互交配构成综合群体,其后按基本方案进行的轮回选择。     

Progress and cumulation in the human sciences after the fall

What do we mean by progress and cumulation in the social and human sciences? Recent thinking in the philosophy and history of science has led to an abandonment of some versions of logical positivism and of verificationism that had a strong deductive and theory testing orientation. What is to replace them is less clear. This paper argues that progress and cumulation can be seen as a process of evaluation and retention within an epistemic community. Scholarly disciplines differ in their social structure and in their epistemic and normative commitments. Since sociology is a fragmented discipline, progress and cumulation differ within its multiple subdisciplines, which to varying extents represent epistemic communities. Brief sketches of progress (advance) and cumulation in several subdisciplines are offered.

First Nations and community economic development: a case study

A training project in a northern Canadian community providedan opportunity to examine participatory planning approachesand the meaning of work in First Nations communities. Focusgroups conducted three years after the unsuccessful interventionof a community economic development (CED) project suggest thatcomplex factors such as lack of support from community leadersand rate of pay for workers determine whether CED is alwaysappropriate in northern, First Nations contexts.     

宗教社会学范式及理论的新进展

20世纪90年代以后,宗教社会学领域出现了新的理论范式。新范式是理解美国宗教的框架,旧范式则来源于欧洲的宗教传统。新范式的内容包括理性选择理论、似真性理论和仪式理论。目前,新范式开始运用于中国、印度等国家的宗教研究,似乎要成为普世性的理论模式。
