培养学生倾听和表达的口语交际能力,使学生具有文明和谐的人际交流素养,是语文教学的重要任务,对学生终身发展的必要性也越发凸显。而以书面语教学为主的传统语文观的语言能力和交际能力的脱节,致使口语交际教学发展滞后。小学阶段是个人发展语言的黄金时期,如何及时转变口语交际教学观念,跳出旧模式的窠臼,成为小学语文教育中的重要课题。教师只有提高认识,不断探究,寻找对策,才能使不尽如人意的口语交际教学现状得到改观。现就其教学效率的提高谈一些浅见。  相似文献

近20年来,我国高等职业教育得到了飞速发展,已进入内涵建设的关键时期.当前,我国的高职教育理念存在误区,普遍存在重技能、轻素质,重智育、轻德育的“偏科”现象,加强思想品德和人文素质教育势在必行.高职院校必须转变教育观念,把“做事”和“做人”结合起来,提高学生的综合素质,实现“能力本位”向“素质本位”转变,从而真正培养出德、智、体、美全面发展的高素质技术技能型人才.  相似文献

国家对农村义务教育的财政投入,有力推动了农村地区义务教育事业的快速发展。而如何对农村义务教育财政进行有效的监督,以保证有限的资源发挥出最大的效益,是当前亟待解决的问题。从制度变迁的视角,对义务教育财政监督体制的发展历史做了回顾。农村义务教育财政监督方面还存在一些问题,如义务教育财政监督机制不健全,义务教育财政监督存在滞后性和被动性,义务教育财政监督的方式单一以及对违法违纪制裁无力,因此,应对义务教育财政进行全程监督,引导公众舆论监督农村义务教育财政,义务教育内部财政监督主体也应成为被监督的对象,完善对义务教育财政违法的惩罚机制。  相似文献

Franchising has rapidly grown in Saudi Arabia since 2005, yet a small number of the large companies dominate the market with mostly foreign brands. Therefore, the aim of this study is to investigate the barriers that Saudi small and medium enterprises and startups face when striving to become franchisors or franchisees. These barriers are investigated through the use of semi-structured interviews with people who belong to the franchise community either as administrators, franchise committee members, franchise developers, franchisees–franchisors, or prospective franchisees and franchisors. The results of this study show that there are several barriers standing against using franchising as a mode of expansion and investment by small and medium enterprises and startups, such as lack of legal, financial, institutional, marketing, development, and educational services support, and other key factors related to international franchisors' preferences and domestic franchising.  相似文献

Between 2001 and 2005, the US airline industry faced financial turmoil while the European airline industry entered a period of substantive deregulation. Consequently, this opened up opportunities for low-cost carriers to become more competitive in the market. To assess airline performance and identify the sources of efficiency in the immediate aftermath of these events, we employ a bootstrap data envelopment analysis truncated regression approach. The results suggest that at the time the mainstream airlines needed to significantly reorganize and rescale their operations to remain competitive. In the second-stage analysis, the results indicate that private ownership, status as a low-cost carrier, and improvements in weight load contributed to better organizational efficiency.  相似文献

Despite the explosive growth of the Chinese aviation sector and the major industry reforms undertaken in recent decades, the Chinese domestic market remains highly concentrated with a significant element of regulation and governmental control in areas such as market entry and airline fleet planning. In this study, we investigate the frequency strategies and aircraft choices of airlines operating in this concentrated growth market. Our empirical investigation suggests that airlines mainly accommodate rapid traffic growth by flying more frequently, although increased aircraft size also contributes to market expansion. We also find a negative relationship between market concentration and flight frequency. Due to the more balanced market structure resulting from mergers among leading airlines since 2002, there has been a moderate reduction in market concentration at route level, contributing to a 3.7% increase in traffic volume from 2002 to 2008. The results of our study suggest that Chinese travelers have yet to fully enjoy the benefits of market liberalization, and airports should prioritize increasing capacity related to aircraft movements over the accommodation of larger aircraft.  相似文献

This paper examines the cost structures of the leading integrated air cargo carriers, FedEx Express and UPS Airlines. A total cost model is estimated for the two carriers using quarterly data on domestic operations and costs over a nine-year period (2003–2011). The estimated model indicates that the integrated industry exhibits increasing returns to traffic density and constant returns to scale. Accounting for carrier-specific differences in cost structure and network size, FedEx Express is found to be more cost-efficient than UPS Airlines. Looking at the carriers individually, UPS Airlines exhibits substantial economies of traffic density and constant returns to scale while FedEx Express' cost structure is characterized by weak economies of density and constant returns to scale. The combined effect of returns to density and returns to scale on the cost structures of integrated carriers is captured by economies of size. Both FedEx Express and UPS Airlines exhibit economies of size, indicating that carriers in the integrated industry can be more cost efficient by making appropriate adjustments to their network size as their output grows. Moreover, the relative cost-efficiencies of the carriers are reversed when their network-size differences are not controlled.  相似文献

This article studies a container drayage problem with flexible orders defined by using requiring and releasing attributes as a unified formulation of various order types. A determined-activities-on-vertex (DAOV) graph introduces a temporary vertex set to formulate different truck statuses. The problem is formulated as a mixed-integer nonlinear programming model based on the DAOV graph. Four strategies including a window partition based (WPB) strategy are presented and evaluated extensively to solve the problem. Results indicate that the WPB method could solve the problem effectively and efficiently. Furthermore, this method is robust considering the operating time biases compared to other algorithms.  相似文献
