理解障碍和《高等数学》教学困难及对策

该文从数学理解的高度,分析了数学学习困难的课程内在原因和当前教育体制的局限性,以及克服这些障碍的一些对策。理解在数学学习中占有重要的地位,因此数学理解障碍是数学学习中的一种重要障碍,如果不注重学生是否具有理解的意向,不了解学生的认知水平,就不能帮助学生克服障碍。在教学上,可以通过创设恰当、有趣的教学情境、帮助学生生成正确的数学表象、注重数学交流等途径来排除理解障碍。

我国城市化进程中城乡社会保障制度的对接

我国城乡分割的二元社会保障制度已经不能适应改革开放的需要,亟待改革,建立覆盖城乡的统一社会保障体系.这一工作面临诸多障碍,为了顺利实现城乡社会保障制度的对接,就必须转变观念,建立多元化筹资体系,构建多层次农村社会保障体系,分地区、分步骤、有差异地进行,建立全国统一社会保障网络,改革现行户籍制度.     

International Export Orientation and Firm’s Performance: Evidence from Enterprise Survey Data of India

This study aims at analyzing the performance of firms by international export orientation vis-à-vis domestic orientation, based on World Enterprise Survey Data of 9,281 firms of India. Simple statistical techniques such as chi-squared test, ANOVA, and regression model have been used to analyze the data with the help of SPSS version 20.0. Chi-square statistics indicate that there is significant difference in enterprise characteristics by business orientationdomestic versus export-oriented businesses. Result of the ANOVA indicates a significant difference in business performance between export versus domestic orientation of firms in terms of sales and employment growth rates. Export-oriented enterprises perceive comparatively fewer obstacles than domestic enterprises. Regression analysis indicates that enterprise characteristics, performance indicators, and business obstacles have influence on export orientation of the firms. This study provides insights on differences in firms’ performance across business orientations and factors affecting the internationalization of business. This study can be helpful in designing policies for promoting export-oriented enterprises in a focused manner.     

Allocating Capacity Among Quality Differentiated Products: Evidence From Airline Industry

Prior analytical literature has shown that the capacity-allocation decisions depend on the quality differentiation and the resource consumptions of products. However, there has been no empirical investigation on this topic in vertically differentiated markets. In this article, the authors investigate the airline industry in three regions of the world; Asia Pacific, Europe, Middle East, and Africa, and North America. They explore how the customer perceived quality and the resource-consumption differences of the products may affect the capacity-allocation decisions. They find that both attributes have a significant impact in all the regions, yet at a different scale in each region.
