This paper provides emic and etic interpretations of engagement with a consumer-to-consumer (C2C) online auction site, based on in-depth interviews with buyers. The study exposes three misconceptions about online C2C auctions; that the interaction between parties occurs exclusively online, that the relation between buyers and sellers is purely transactional in nature, and that the interaction between buyers and sellers does not lead to ongoing business relationships. The paper reveals the utilitarian, hedonic and social benefits that are the bases of engagement with the auction site. Social benefits materialize for auction buyers during offline exchanges. The paper also reveals marketer incentives and structural disincentives for consumers' ongoing use of the auction site.  相似文献

Prevention of chemical incidents is an important issue in the chemical petroleum industries. This issue is receiving focus and attention from a wide spectrum—Industry, Labor, Professional Associations, Environmental Groups Government and the Public. The purpose of this paper is to review the various regulatory initiatives and related activities regarding chemical process safety.  相似文献

There is reason to believe that consumers face a difficult task in securing adequate and accurate information upon which to judge relative price levels of competing foodstores. The objective of the research reported here was to investigate the potential of retail food price reporting for correcting this information problem. Both consumer and grocery retailer responses to this comparative food price information were analyzed. A pretest-post-test design with four pairs of experimental-control cities (with replications at two levels of concentration) was employed to collect price data. A modified Solomon-four group design was used for surveys of food consumers in experimental and control cities. The results of analysis of variance models lend support to the hypothesis that price reporting can lower the relative level of food prices, both for items individually identified in a price report and items not identified in the report. The magnitude of this effect varied among the cities. It appears that consumers' role in this experiment was a passive one: consumer behavior and patronage patterns did not change in a manner that would consistently reinforce the competitive effects of the price reports.  相似文献

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but adoption has been slow. This article determines the expected profit from using a plant-sensing system to determine winter wheat nitrogen requirements. We find that plant-sensing systems have the potential to be more profitable than traditional nonprecise systems, but the existing system simulated was roughly breakeven with a traditional system.  相似文献
