This study examines the perceived usefulness of alternative spatial and tree-based similarity scaling techniques in a market analysis task. These techniques are typically evaluated on their ability to fit or explain customer input data. The psychological reaction of individuals who use these techniques to analyze markets has been largely ignored. The study reveals that spatial representations are perceived as more useful than tree-based clustering techniques, even though the latter provide a better fit to customer perceptions. The results have implications for both the use and development of scaling techniques in psychology and marketing. © 1996 John Wiley & Sons, Inc.  相似文献

Through research on a sample of the top 2000 charities, the Voluntary Organisations Internet Server (VOIS) revealed the potential for a major initiative to provide the opportunity for voluntary organisations to create a quality brand of information on the Internet by coming together on a collective site. The Internet is an ideal medium for voluntary organisations to get their message across, build relationships and raise funds. VOIS has been designed specifically to facilitate these activities and provide the means to a collective presence. While it is mainly large organisations that are using it at the moment, the Internet represents the opportunity for smaller organisations to have a substantial presence because of its democratic nature. VOIS has utilised the principle of economies of scale in order that all organisations can afford to have a useful presence on the Internet. This paper will examine fundraising activities that are already occurring on the Internet, analyse the strengths of the Internet as a marketing tool, explain how marketers can utilise these strengths and explain how VOIS has tried to facilitate these strengths within the features of its standardised site.  相似文献

The credit cycle implicit in Wicksell's upward cumulative process (UCP) is described. UCP may be interpreted as a stable cycle with two phases and an upper turning point corresponding to the maximum 2-rate-differential. The volume of credit and the rate of inflation is shown to expand in phase 1 and to contract in phase 2. The role of velocity increasing in causing a higher inflation rate is also described. This cycle has not been noticed in the literature because Lectures(2) was unclear about how long it would take to reach an upper turning point. But, Interest and Prices emphasized that the continuous return of the inflation rate to zero equilibrium would begin after a relatively short period.  相似文献

Great hopes have been placed in the sharing economy to provide a new business model based on peer-to-peer (P2P) exchanges of underutilized assets. As a model, the sharing economy has been expected to make significant contributions to sustainability, providing new opportunities for entrepreneurship, more sustainable use of resources, and consumer co-operation in tight economic networks. However, in recent years, digital platforms have turned into the most important actors in the global sharing economy, turning global corporations, such as AirBnB, Booking, or TripAdvisor into intermediaries controlling and profiting from most transactions. Focused on accommodation, this paper conceptualizes the sharing economy in comparison to the wider collaborative economy, and discusses its social, economic, environmental, and political impacts in comparison to the sustainable development goals. It concludes that the sharing economy has great potential to make very significant contributions to sustainability, though the model is increasingly being replaced by the collaborative economy, which performs as an extension and acceleration of neoliberal economic practices.  相似文献

Bob Quinn spent 20 years propagating an ancient Egyptian wheat variety that is generally known as Khorasan wheat. Bob trademarked his wheat variety using the brand name "Kamut®." Kamut® brand wheat contains some nutritional, health, and taste advantages over modern wheat varieties, but lacks some of modern wheat's agronomic advantages. Kamut® brand wheat is organically produced, and is used to make cereals, breads, cookies, snacks, pancakes, bread mixes, bulgur, pasta, and baked goods. Whole wheat products produced from Kamut® brand wheat are less bitter than those produced from modern wheat varieties. Europe represents approximately two-thirds of the market for this product.  相似文献

By using Bourdieus’ thinking tools field, habitus and capital, this article first develops a concept of the journalistic field, in which economic capital and journalistic capital decide on (collective and individual) agents’ latitude and in which their autonomy could be influenced by economic logic, the discussion on journalistic norms and the logic of other social fields. Subsequently, this concept is implemented in a qualitative study. For that purpose 501 guideline interviews with journalists were conducted; they were asked about their career, their working conditions and their role perception. The findings show that in Germany nowadays the journalistic field is dominated by information professionals, who know their craft and who made the needs of the audience the benchmark of their work. Different from what literature suggests, it makes little sense to differentiate between a “commercial” and an “intellectual” pole. Exclusive news (which is what the field is all about) can only be produced where enough capital is available. At the centre of power, to which news magazines, national daily newspapers and public broadcasting stations belong, one can most easily withdraw from the economic logic and the influence that emanates from the audience and the advertising clients.  相似文献
