Portfolio analysis has become a widely used strategic planning tool in many industries during the past decade. Strategic decisions in the tourism industry include issues such as which markets are most attractive (e.g. have greatest visitor expenditure potential); in which markets are a specific country's “products” most competitive; how promotional budgets should be allocated for greatest effectiveness; and what the promotional message should convey. Industry Attractiveness Analysis—a flexible variety of portfolio analysis—has been applied to the generating countries which supply tourists to New Zealand in an illustrative case study. Both national level and individual company applications are described and illustrated in 3 × 3 matrix form. These diagrams are, in themselves, a good communication mechanism which encourages rational, strategic thinking about managerial decisions and resources allocations. Past, present, and future situations can be portrayed in a graphically useful manner.  相似文献

The author challenges the conventional wisdom that the main risk to Western development is environmental degradation caused by mankind. Concern over the greenhouse effect and global warming have more to do with millenium fever than reality. There is still very little evidence to suggest that these environmental phenomena result from human activity. What we do know is that there have been major cyclical fluctuations throughout history. The author cautions against implementing ‘scientistic’ policies in the face of such doubts, just because it is trendy to do so.  相似文献

It is generally accepted that moving from an unfunded to a funded social security system implies a welfare loss for the transition generation—that is, the generation that has to pay twice: first, saving for its own retirement and, second, contributing to the pensions of the then retired generation. This article shows that in a setting of endogenous growth with positive externality such a transition can be Pareto improving. But it argues also that social security reform is more a pretext than a requirement for internalizing such a positive externality.  相似文献

Public services in the UK are increasingly expected to account for their outputs and performance. This article describes a retrospective evaluation of the benefits from the R&D funded by a regional office of the NHS Executive. The methods adopted enabled the various elements of the region's R&D portfolio to be examined and provided a basis for the development of a plan for regular monitoring. The proposals for implementation are now also feeding into a debate as to how health services R&D might best be monitored nationally in a way that is compatible with the norms and practices of research in other contexts.  相似文献

Critical analyses of the audit profession have become more common in recent years. Many of these analyses focus on the entire audit profession in developing their criticisms and concerns. In this paper, the scope of analysis is narrowed to examine in depth the auditing profession's use of the concepts of reasonable assurance and materiality in audit performance and audit communications. Reasonable assurance and materiality are the terms that auditors use to describe the scope of their responsibility to the public. Similarly, reasonable assurance and materiality are the key determinants of audit effort. An overview of official guidance, practitioner reports, and academic research reveals that these two key concepts are not well specified nor are they consistently applied in audit practice. These findings are evaluated from two competing perspectives on professions – the traditional, functionalist perspective and the critical theorists' perspective. Evaluation from the latter perspective leads to a conclusion that the profession's use of these key terms to guide practice and communication leaves the profession open to charges of mystification and unjustified paternalism.  相似文献

Since the 1970s the number of developments labelled as innovation intense environments has increased at an exponential rate. Innovation intense environments are defined here as those spaces that are purported to accelerate the rate of innovation and the proliferation of high technology industries. A number of academic fields now study existing innovation intense environments like Silicon Valley, in order to explain how they are constituted and how they can be replicated.

 Over the years a wide variety of model innovation intense environments has been proposed including: science park, technopolis, information city, milieu, industry cluster and regional innovation system. These different models are compared and analysed in terms of their portrayal of appropriate form, core innovation dynamics and policy recommendations. The discussion of models is then placed within the post-war history of the most famous innovation intense environment—Silicon Valley. It is concluded that such models must be well grounded within a specific historic and cultural context in order to function as useful analytic tools.  相似文献

Intangibility has long been studied as a unidimensional construct with the focus being placed upon the physical element. This paper explores the effects of three unique intangibility dimensions on a consumer's ability to evaluate goods and services, and the perceived risk (PR) associated with the transaction. The authors examine these relationships in purchase environments that include both traditional bricks-and-mortar retailers and the Internet. Their investigation further incorporates prior knowledge as a moderating factor into the proposed framework. This allows for a thorough comparison of the effects and relationships that exist between intangibility and its consequences in general, evaluation difficulty (ED) and perceived risk (PR) in particular. The authors develop hypotheses pertaining to the proposed model and test them with two experiments. The empirical results are broadly supportive of the hypotheses. Theoretical and managerial implications to the services marketing literature are discussed.  相似文献

We propose an approach for deriving joint space maps of bundle compositions and market segments from three-way (e.g., consumers x product options/benefits/features x usage situations/scenarios/time periods) pick-any/J data. The proposed latent structure multidimensional scaling procedure simultaneously extracts market segment and product option positions in a joint space map such that the closer a product option is to a particlar segment, the higher the likelihood of its being chosen by that segment. A segment-level threshold parameter is estimated that spatially delineates the bundle of product options that are predicted to be chosen by each segment. Estimates of the probability of each consumer belonging to the derived segments are simultaneously obtained. Explicit treatment of product and consumer characteristics are allowed via optional model reparameterizations of the product option locations and segment memberships. We illustrate the use of the proposed approach using an actual commercial application involving pick-any/J data gathered by a major hi-tech firm for some 23 advanced technological options for new automobiles.  相似文献

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.  相似文献
