浦东新区的极化开发形成了区际迁移和省际迁移两股人口迁入流.由于来源地不同,他们在年龄、受教育程度、行职业、收入和居住等方面形成了分异现象,与此同时,也产生了社区重构、社会极化和社会矛盾等问题.劳动力市场分层响应和城市生态位势空间响应是迁入人口分异的主要响应机理.迁入人口的分异问题会影响浦东新区的社会稳定和发展,因此,必须引起足够重视.  相似文献

This research aims to understand the performance of purchasing social responsibility (PSR) through moderating effect of purchasing strategic integration. The results show that PSR directly influences purchasing performance, while the relationship between PSR and purchasing performance is partially mediated by organizational learning. Moreover, strategic integration negatively moderates the relationship between PSR and purchasing performance. This study suggests that the adoption of PSR affects the operations of both buyers and suppliers in a supply chain that further encourage organizational learning and increases purchasing efficiency. The results also show that organizations may realize this effect of PSR practices but may focus on other purchasing practices, which affects purchasing performance. Copyright © 2018 ASAC.

Validating the international tourist role scale   总被引:1,自引:0,他引:1  
This study was designed to validate the international tourist role scale and the three dimensions it revealed. The purpose of this attitudinal scale was to measure the tourist role typology. United States adult outbound tourists flying with 11 major airlines returned useful questionnaires. This study validated the role scale as a reliable one that properly identified three conceptual dimensions of international tourist typology and successfully provided measures of tourists’ novelty-seeking preferences on the three dimensions. The study demonstrated, however, that the scale would measure the novelty-seeking preferences of international tourists more effectively if it were supplemented by other measures.  相似文献

This paper addresses a controversial topic in tourism scholarship which is simultaneously a problem and an opportunity in tourism education: the philosophical issue of academic disciplines and specifically, the question of a distinct discipline in tourism studies. It is argued that the orthodox approach to tourism education, multi-disciplinary studies, has become an impediment. It is suggested that a new discipline can be created by organizing the existing body of knowledge and that such a discipline can become the core of an inter-disciplinary approach. Certain characteristics of an embryonic discipline are outlined and innovations in this area at Sydney Technical College are discussed.  相似文献

Colleges and universities in the US differ markedly in their access to economic resources. National data are used here to describe the resulting hierarchy that's reflected in schools' spending on their students, the prices those students pay, and the subsidies they get in consequence. Both historical data and projections based on recent institutional saving suggest that economic disparities among institutions and their students are increasing. In a final section, the paper asks what to make of this: what we can say about the right degree of institutional disparity – whether we have too much, too little, or about the right amount of differentiation.  相似文献

This paper summarizes the approach and main findings of a research study undertaken by the Tourism Society into occupations, career profiles and knowledge requirements of professionals engaged in tourism. It outlines the main stages in the research program, including the identification of a body of knowledge about tourism, the development of an occupational classification, and a survey of professionals employed in tourism. It then presents and comments on findings covering occupational classifications, career profiles and knowledge requirements, making particular reference to the implications for tourism education. The study is very much a pioneering work in this field and it is confined to the experiences of the United Kingdom.  相似文献
