Pragmatism in Economic Methodology: The Duhem-Quine Thesis Revisited

Contemporary developments in economicmethodology have produced a vibrant agenda ofcompeting positions. These include, amongothers, constructivism, critical realism andrhetoric, with each contributing to the Realistvs. Pragmatism debate in the philosophies of thesocial sciences. A major development in theneo-pragmatist contribution to economicmethodology has been Quine's pragmatic assaulton the dogmas of empiricism, which are nowclearly acknowledged within contemporaryeconomic methodology. This assault isencapsulated in the celebrated Duhem-Quinethesis, which according to a number ofcontemporary leading philosophers of economics,poses a particularly serious methodologicalproblem for economics. This problem, asreflected in Hausman's analysis, consists ofthe inability of economics to learn fromexperience, thereby subverting the capacity totest economic theories. In this paper wedispute this position. Our argument is basedon a combination of Quine's holism with VanFraassen's constructive empiricism, especiallythe latter's analysis of empirical adequacy andhis pragmatic approach to explanation. Theresulting reorientation of economic methodologyrestores the capacity of economics to learnfrom experience and reinstates the imperativeof developing alternatives to orthodoxtheorizing in economics.     

论法律部门的划分标准与经济法的地位

传统法律部门的划分因其片面强调客观性和按法律调整的社会关系的性质来划分法律部门而有着固有的、难以弥补的缺陷，因此要令人信服地说明经济法作为独立的部门法的地位，就必须抛弃旧的框框，按主客观一致，以主观为主导的指导思想。重新来确定法律部门的划分标准。

A ROBUST DECOMPOSITION OF LINEAR PROGRAMMING USING A GOAL-PARTITIONING METHOD

The Dantzig/Wolfe linear programming decomposition algorithm has had important economicinterpretations as well as a widespread impact on solving large scale linear programming problem.Inthis paper we consider a similar underlying structure,where however there is only one couplinginequality or equation.With this simplification,we demonstrate how to achieve an equitable partitionof the overall coupling resource to individual subproblem constraints through a simple iterationprocedure which appears to be very efficient.     

两段绞接式联合收割机输送槽的设计研究

本文介绍一种适宜配置在悬挂式联合收割机上的两段铰接式输送槽设计,这种输送槽后段固定,前段与割台连接并与后输送槽铰接,该铰接点为前悬挂割台的支点,借助液压油缸升降,文中对该铰接点位置的确定,以及两段输送槽铰接处的圆弧过渡板设计进行了分析研究,提供了设计方法.     

管道纺包芯纱的研究

本文研究了在管道纺纱机上不添加构件而进行包芯纱的纺制。分析了其包芯纱的成纱机理。观察了实际成纱的横截面,证实了棉纤维能够均匀地、完全地包覆在芯丝的周围。也对不同性质的芯丝所纺包芯纱的结构作了观察,并对不同成纱的性质随速度增加而变化的规律作了研究。     

社会主义发展的历史进程与经济全球化的理性发展

社会主义的兴起及其曲折发展与经济全球化的形成和不断推进有着密切的关联，而社会主义力量的存在和发展又是推动全球化朝着公正合理方向发展的重要因素。     

高含沙水流河床稳定性试验研究

利用过程响应模型试验原理,模拟了高含沙水流河道的形成过程,从平面、横断面和纵向变化3方面揭示了高含沙水流窄深河道的形成过程及河道形态特征。试验结果表明:在高含沙窄深河道形成初期,河道平面摆动剧烈,同时水流漫滩并大量淤积,河床抬高,主槽保持窄深形态;在后期,水流不漫滩和保持高含沙水流的条件下,这种单一窄深河道形态变化较小,在空间和时间上都能够相对稳定。
