This study uses the strategic group theory to identify business strategies and competitive advantages implemented by Spanish hotels, which are grouped together according to three variables (size, chain affiliation, and category) and the degree of development of the different business strategies. An analysis carried out with the aim of checking the potential existence of significant differences in performance among the strategic groups revealed that the highest performance levels are achieved by larger-sized, chain-affiliated, and higher-category hotels as well as by establishments which base their competitive advantage on category and capacity or size and internal management.  相似文献

The use of genetically modified (GM) crop technology in tackling food security problems and poverty reduction in Africa continues to generate debates over its benefits and safety. Only four countries, South Africa, Sudan, Burkina Faso and Egypt have commercialized GM crops in Africa but controversy surrounds current cultivation of GM maize in Egypt. Our study provides new perspectives on the status, development and regulation of GM crops through examining the views of 305 stakeholders in six African countries across four regions: South Africa, Kenya (East Africa), Egypt and Tunisia (North Africa), Ghana and Nigeria (West Africa), supplemented by interviews with relevant international organizations. The study revealed the challenges leading to the development of biosafety regulatory frameworks and the role of individual stakeholders in the facilitation of GM crops across African countries. This study also revealed that some countries may go through a Fiber–Feed–Food (F3) approach to adopt GM crops where Bt cotton will be adopted first followed by GM crops for livestock feed while undergoing all the necessary assessments before producing GM foods for human consumption. An overwhelming majority of stakeholders placed emphasis on risk analysis (risk assessment and management) in view of limited capacity, lack of scientific expertise and public concern, and encouraged a centralized approach to risk assessment similar to the European Union model of the European Food Safety Authority (EFSA).  相似文献

Group Support Systems may be “distributed”; for nonsimultaneous use by being embedded in a Computer‐Mediated Communication System (CMCS). In this manner, large groups may use them for complex tasks over an extended period of time. Will executives use such systems, and what are their reactions? This case study of elites engaged in formulating recommendations for the White House Conference on Productivity demonstrates that executives can use such systems, given that “critical success factors”; are met. Perceived information richness is strongly correlated with perceptions of productivity enhancement as a result of system use.  相似文献

This paper evalutes a three year programme in a UK university which recently won the Partnership Award from Cooper & Lybrand, Deloitte for innovation in higher education. The programme aims to encourage student to work in groups and to reflect upon the processes and the group dynamics involved. The first part of the paper provides the context for the paper and the context in which the programme runs. n example of a case study used in the programme is described in detail and the way in which it draws together subject areas within the degree is illustrated. Finally the programme is evaluted in terms of its successes and its problem areas.  相似文献

An Asynchronous Learning Network (ALN) is a Computer-Mediated Communication System designed to support "anytime/anywhere" interaction among students and between students and instructors. A field experiment compared groups and individuals solving an ethical case scenario, with and without an ALN, to determine the separate and joint effects of communication medium and teamwork. Dependent variables include quality and length of the reports, and subjective perceptions of learning and satisfaction. The results indicate that that an ALN enhances the quantity and quality of the solutions to an ethical case scenario. The combination of teamwork with ALN-support increases the students' perception of learning. Although the perception of collaborative learning was similar between ALN-supported and unsupported groups, participants in computer-mediated groups reported lower perceptions of discussion quality than participants in manual groups.  相似文献

This paper examines the self-interested reasons that businesses can have for ethical behaviour. It distinguishes between economic and non-economic reasons and, among the latter, notes those connected with the self-esteem of managers. It offers a detailed typology of prudential reasons for ethical behaviour, laying particular stress on those to do with avoiding punishment by society for wrongdoing and, more particularly still, stresses the role of campaigning pressure groups within that particular category of reasons. It goes on to suggest that because of their occupation of the moral high ground, campaigning groups are well placed to damage the self-esteem of managers and that this is why those groups seem able to exert an influence that goes beyond their somewhat limited capacity to inflict economic damage upon businesses. The paper concludes with the suggestion that we may be witnessing a virtuous spiral whereby rising public expectations of morality in business lead to ever increasing moral commitments by business that then cause those expectations to rise still further.  相似文献

This paper has two objectives. The first is the documentation of the relative importance of the largest financial groups in the world. The list of top 50 financial groups ranked by total assets in 2003 is compared to a similar list available for 1986. The second objective is to examine where financial firms are expanding their operations and to document some of the factors that may explain the most-favoured locations of these financial groups.The results of this study have two important implications. First, they indicate that location-specific advantages such as size, human capital and cultural distance, do provide an explication of the internationalization of financial firms. Second, they show that good governance has a strong impact on the choice of countries by firms.  相似文献

We investigate the role of trade credit as a source of financing. Using a sample of 661 large non-financial Belgian firms for the 1989–1991 period, we find that the amount of trade credit a buyer takes is determined by his need for funds and the internally available funds. Trade credit is primarily used to finance short-term assets. As such, it seems to be an important alternative not only for short-term bank debt but also for long-term financial debt, including intragroup debt. We find no evidence that the amount of trade credit taken is influenced by affiliation with the supplier.  相似文献

We consider a model of vertical product differentiation where consumers care about the environmental damage their consumption causes. An environmental group is capable of increasing consumers’ environmental concern via a costly campaign. We show that the prospect of such a campaign can induce entry by a firm that is able to employ a cleaner technology than the one used by the incumbent. We further demonstrate that the subsequent competition can lead to an adverse effect on aggregate pollution, i.e. the decline in average industry pollution per product is offset by the increase in aggregate production.   相似文献
