南宋理学极盛的过程与原因试析

宋代理学到南宋孝宗、宁宗时期达到极盛 ,但无论从理学道统承传方面还是从社会政治条件方面看 ,孝宗之前的高宗朝实为理学发展的关键时期。理学由北宋时的民间之学发展到南宋时占主导地位的学派 ,活跃于高宗朝的程门弟子对二程学说的极力推展是一重要因素。同时 ,面对激烈的民族矛盾 ,高宗集团选择了主和派的妥协主张 ,并有意识地寻找与这一政策相适应的学术思想作为其理论根据 ,程系理学正是在这一现实政治需要中得到高宗集团的接纳、支持而逐渐繁荣兴盛起来。到孝宗朝 ,朱熹使理学形成庞大的思想体系 ,标志着中国古典哲学进入了一个新阶段。     

Statistical and Combinatorial Aspects of Comparative Genomics*

Abstract. This document presents a survey of the statistical and combinatorial aspects of four areas of comparative genomics: gene order based measures of evolutionary distances between species, construction of phylogenetic trees, detection of horizontal transfer of genes, and detection of ancient whole genome duplications.     

Assessing goodness-of-fit of categorical regression models based on case-control data

Demonstrated equivalence between a categorical regression model based on case‐control data and an I‐sample semiparametric selection bias model leads to a new goodness‐of‐fit test. The proposed test statistic is an extension of an existing Kolmogorov–Smirnov‐type statistic and is the weighted average of the absolute differences between two estimated distribution functions in each response category. The paper establishes an optimal property for the maximum semiparametric likelihood estimator of the parameters in the I‐sample semiparametric selection bias model. It also presents a bootstrap procedure, some simulation results and an analysis of two real datasets.

新形势下农资价格大幅上涨对“三农”的影响分析

文章首先以湖北省襄樊市的调研数据为依据对此次农资价格整体变动情况作了说明，紧接着对本轮农资价格大幅上涨的深层次原因、趋势及其对“三农”的影响作了深入剖析。结果表明，农资生产原料价格的迅猛上涨是此次农资价格上涨的导火索与根本推动力量，农资上涨基本上冲销了中央一系列惠农政策带给农民的实惠，使农民的种粮积极性遭受很大挫伤。最后从放开价格、加强宏观调控、改变补贴方式、健全营销网络、完善储备制度、加强市场监管及监测等方面提出政策建议。     

翻译:意识形态的建构、解构、重建与解读

翻译不仅是语言之间信息转换的文化活动,而且是一系列复杂的思维活动。意识形态以不同的语言形式隐藏在语篇之中,以各种隐蔽方式潜移默化地影响着作者写作、译者翻译以及读者解读文本。本文拟以批评语言学为主要方法论,强调翻译中语言分析和社会分析相结合的重要性,同时主张翻译研究应以语篇为单位,特别注意考察作者、译者、读者在翻译过程中的三元关系及其在意识形态的建构、解构、重建和解读过程中的作用,以便弄清翻译的本质并有效地解释那些"不忠"的现象。     

评鲍德里亚的"消费社会理论"

鲍德里亚系统提出了"消费社会"的理论。他企图对唯物史观进行"颠覆"是错误的。但是不能简单地认为他是资本主义制度的辩护士。鲍德里亚不懂得马克思从根本上颠覆了国民经济学和唯心主义历史观的两种"幻象",从而奠定了生产和劳动对于人类社会存在与发展的基础性地位;不懂得消费与生产的现实辩证关系,片面地离开生产探讨消费的新特征,甚至主张用消费取代生产。消费异化是劳动异化的表现。技术救赎不可能解决当代人类面临的重大社会问题。     

团队生产、计量难题与企业的性质

阿尔奇安和德姆塞茨(1972)从团队生产引发的“计量难题”及其解决机制的角度来解释企业的性质。本文在概述该企业理论的概念框架的基础上,指出了该理论存在的一个缺陷,即它忽视了企业的监督者-剩余索取者和其他成员之间的利益冲突及其解决机制。     

Quantifying uncertainty in the biospheric carbon flux for England and Wales

Summary.  A crucial issue in the current global warming debate is the effect of vegetation and soils on carbon dioxide (CO₂) concentrations in the atmosphere. Vegetation can extract CO₂ through photosynthesis, but respiration, decay of soil organic matter and disturbance effects such as fire return it to the atmosphere. The balance of these processes is the net carbon flux. To estimate the biospheric carbon flux for England and Wales, we address the statistical problem of inference for the sum of multiple outputs from a complex deterministic computer code whose input parameters are uncertain. The code is a process model which simulates the carbon dynamics of vegetation and soils, including the amount of carbon that is stored as a result of photosynthesis and the amount that is returned to the atmosphere through respiration. The aggregation of outputs corresponding to multiple sites and types of vegetation in a region gives an estimate of the total carbon flux for that region over a period of time. Expert prior opinions are elicited for marginal uncertainty about the relevant input parameters and for correlations of inputs between sites. A Gaussian process model is used to build emulators of the multiple code outputs and Bayesian uncertainty analysis is then used to propagate uncertainty in the input parameters through to uncertainty on the aggregated output. Numerical results are presented for England and Wales in the year 2000. It is estimated that vegetation and soils in England and Wales constituted a net sink of 7.55 Mt C (1 Mt C = 10¹² g of carbon) in 2000, with standard deviation 0.56 Mt C resulting from the sources of uncertainty that are considered.
