公式化语言在心理词汇中在线处理的研究综述

公式化语言是语言的重要组成成分,目前从心理语言学和二语习得方面时其研究还较少,尤在国内更少.文章主要从心理语言学角度对现有的公式化语言相关研究及其研究方法进行综述,讨论这些研究的结果以及其局限,分析现有研究对今后公式化语言在心理语言学和二语习得方面研究方向的启示.     

Trust, tenure insecurity, and land certification in rural Ethiopia

This paper assesses the impact of a land certification program in Ethiopia on the level of interpersonal and institutional trust among households in the Amhara region. The land certification program is designed to enhance land tenure security of farmers, by maintaining (egalitarian) status quo land distribution and equity concerns. The major contribution of the analysis lies in the exogenous nature of the program which addresses the endogeneity problems that characterize related studies, assessing the impact of policy related variables on trust. The effects of the land certification program on trust are identified both by the difference-in-difference approach and by non-parametrical analysis of average treatment effects. Overall trust is found to be enhanced by the certification program, with trust towards formal institutions being more responsive to the program than interpersonal trust. The major policy implication of the result is that trust could be invested on through policy changes regarding the economic betterment of societies.     

FAMILY VALUES AND THE REGULATION OF LABOR

To be efficient, flexible labor markets require geographically mobile workers. Otherwise firms can take advantage of workers' immobility and extract rents at their expense. In cultures with strong family ties, moving away from home is costly. Thus, to limit the rents of firms and to avoid moving, individuals with strong family ties rationally choose regulated labor markets, even though regulation generates higher unemployment and lower incomes. Empirically, we find that individuals who inherit stronger family ties are less mobile, have lower wages and higher unemployment, and support more stringent labor market regulations. We find a positive association between labor market rigidities at the beginning of the 21st century and family values prevailing before World War II, and between family structures in the Middle Ages and current desire for labor market regulation. Both results suggest that labor market regulations have deep cultural roots.

焙烧温度对介孔CuO/CeO_2变换催化剂结构和性能的影响

采用浸渍法,在不同焙烧温度下制备了CuO/CeO2水煤气变换催化剂并对其活性进行测试,利用XRD、BET、TPR等技术对样品进行了表征。焙烧温度≤650℃,催化剂样品的比表面积和孔容较大,CuO在载体CeO2上分散度高,易于还原,从而具有较好的催化活性;焙烧温度≥750℃,催化剂样品的比表面积和孔容大幅度下降,在载体CeO2上所负载的CuO由于团聚而长大,造成分散度下降,还原温度升高,催化活性变差。研究结果表明,焙烧温度对催化剂样品结构和性能有显著的影响,适宜的焙烧温度是保证CuO/CeO2具有高活性的关键。

Proper generalized neighbor designs in circular blocks

Generalized neighbor designs relax the condition of constancy on the number of times two treatments occur as neighbors in a design. In this paper, we constructed generalized neighbor designs in circular blocks of equal size. Catalogs of these designs for block size 5, 7 and 9 are also compiled. All the designs given here are binary.
