以4,4''''-二(咪唑基亚甲基)联苯为客体的环糊精类轮烷的合成与表征

以4,4'-二(咪唑基亚甲基)联苯(bibp)为客体,通过自组装合成了4,4'-二(咪唑基亚甲基)联苯和环糊精的[3]类轮烷,并通过元素分析,1HNMR,ESI-MS,IR,TG-DSC进行了表征和固体热稳定性等研究,结果表明:由于bibp客体分子链较长,含有两个苯环,所以可穿入两个β-环糊精分子,形成[3]类轮烷.

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.
