Export market orientation behavior of universities: the British scenario     

Yousra Asaad  Geraldine Cohen 《Journal of Marketing for HIGHER EDUCATION》2015,25(1):127-154

This study seeks to extend our knowledge of export market orientation (EMO) in the context of British universities with regard to recruitment of international students. Export marketing remains an area of limited focus in the marketization of higher education literature. The study predominantly follows a quantitative research design using survey methods. A sample of British universities was studied and partial least-squares analysis was performed. The findings indicate that four export higher education-specific variables are important drivers of EMO in universities. The paper also confirms EMO's direct effects on university export performance and its indirect effects mediated through university international reputation. In light of these findings, a number of implications are advanced for university management. The study also makes important theoretical contributions: it contributes to a growing body of literature on marketing of higher education; it enriches the export marketing literature by examining EMO in a service setting and it adds to the EMO–export performance relationship by examining the mediating role of international reputation. The findings are limited to British universities. Therefore, they may not be generalizable to other geographical areas. In addition, the results of this study were obtained from a small sample size and generalization of the findings to other higher education institutions should be made with caution.  相似文献   

基于磁钉技术的集装箱码头AGV 定位精度分析     

李凤娥  牛王强 《上海海事大学学报》2016,37(1):38-41

为解决自动导引车（Automated Guided Vehicle, AGV）的定位精度问题，以国内某在建的自动化集装箱码头为工程背景，研究与基于磁钉技术的AGV定位误差相关的因素.通过给出AGV惯性导航系统的运动方程和误差方程，按照工程实况，在忽略陀螺仪影响的基础上，得到AGV惯性导航系统位置误差的理论计算式.依此指出，基于磁钉技术的AGV组合导航系统定位精度与加速度计精度、AGV 运行方向的余弦、磁钉数据更新时间的平方成正比例关系.最后，对某工程算例进行数值仿真，验证了理论分析的正确性.该方法对磁钉排布、惯性导航系统传感器选型等有参考意义.  相似文献

Football,Place, and Community in a New Zealand Mining Town, 1877–1939     

Charles Little 《国际体育史杂志》2017,34(10):915-934

Abstract

Resource towns (such as lumber camps, power plants, and mining towns) are by their very nature peripheral. They frequently exist in a space of isolation, not only geographically but also culturally as well. The South Island mining town of Kaitangata is a classic example of this process – an industrial, working class, and heavily migrant community positioned within an otherwise agricultural, conservation, and homogenous tract of rural New Zealand. Kaitangata, in the words of one writer, ‘possessed a unique character and pattern of social interaction’ that marked it out from its immediate environment. One way in which these differences manifested themselves was in the sporting activities of the town. In a part of the world where rugby union held absolute hegemony, the town broke the mould by also fielding teams in association football, rugby league, and even Australian Rules football (distinguishing itself as the only town outside of the provincial capital of Dunedin where these three sports obtained a foothold). This paper analyses how these sporting activities contributed to a unique sense of space, addressing themes including class, ethnicity, masculinity, and identity.  相似文献   

基于多元线性回归分析的新疆外贸出口对策研究     

程云洁  董程慧 《连云港职业技术学院学报》2019,(2):18-24

目前,新疆外贸正处于新旧动能转换的关键时期,培育外贸发展新动力是进入新时代外贸的必然要求,新动力的形成主要需要供给方进行动力重塑和协调发力,在出口方面通过创新驱动、结构调整、制度变革培育供给侧新动力。研究结合供给侧改革对新疆外贸出口依存度进行分析,运用Eviews对与出口相关的因素进行多元线性回归分析,得出结论:一是要素禀赋与出口呈负相关关系;二是新疆GDP对出口有显著的促进作用;三是人民币汇率变动与出口额之间表现为强相关关系;四是外商直接投资与出口较强的相关关系。最后针对多元线性回归的结果,提出相应的外贸出口增长对策。  相似文献

增加值出口竞争力研究——基于新兴经济体样本     

《信阳师范学院学报(哲学社会科学版)》2019,(1):41-45

文章使用全球投入产出数据库(WIOD),对新兴经济体样本的增加值出口和新显示性比较优势指数进行测算和分析。研究发现,近年来新兴经济体相对于发达国家出口竞争力强劲,贸易实力提升显著。细分至行业,新兴经济体在第一产业中具有绝对优势,在第二产业的低端和中低端中具备竞争力,在第三产业方面,新兴经济体在传统服务业中具备一定的优势,但在高新技术服务业不具备竞争力。因此,在保留、强化和创新现有竞争优势的同时,新兴经济体仍需要大力发展高端制造业和新型服务业,增加产品科技含量。  相似文献
