This study empirically tests the congruity between movie‐content preference and choice on television, video, and at the cinema; and the impact of consumer involvement on this relationship. The results support the need to treat preference and choice differentially. Media type added little in way of explanation of changes in preference–choice congruence. Involvement with movie choice was found to vary by medium, yet correlational analysis showed that it did not unequivocally change the nature of preference–choice congruence. Nonetheless, further enquiry into the role of involvement is warranted before it is dismissed as irrelevant in the choice of leisure media products. © 2002 Wiley Periodicals, Inc.  相似文献

This study examines the responses of human resource directors and hospitality students to seven different ethical scenarios. Both groups were asked to rate these situations on their ethicality using a Likert-type scale. The directors and students decided that an act of theft was the most unethical, followed by sexual harassment, and an attempt to obtain proprietary information from another company. Expressing racial preferences in terms of servers was fourth. Directors rated all the scenarios ethically lower than did students, indicating that experience and heightened sensitivity to possible litigious situations may have played a role in perceptual differences.  相似文献

Biofortified staple foods hold the potential to alleviate micronutrient malnutrition in many impoverished regions of the world. However, biofortification often alters the flavor, appearance, and other features of foods in ways that may limit consumer acceptance of the new varieties and diminish their impact. This research examined the acceptance of provitamin A-biofortified maize through taste tests and a trading experiment conducted in Maputo, Mozambique. On average, participants ranked the taste, texture, and appearance of their local white maize over an orange, biofortified variety and over a white variety with similar texture and flavor as the biofortified maize. Nonetheless, a large share of participants in a framed experiment accepted offers to trade local white maize meal for meal from the biofortified maize. Household size, the presence of small children, dietary diversity, and perceived taste were statistically significant determinants of acceptance. Results suggest that existing preferences for white maize do not preclude acceptance of orange, biofortified varieties and that provitamin A-biofortified maize may be a self-targeting nutritional intervention.  相似文献

Carbon-accounting methods and reforestation incentives   总被引:2,自引:0,他引:2  
The emission of greenhouse gases, particularly carbon dioxide, and the consequent potential for climate change are the focus of increasing international concern. Temporary land-use change and forestry projects (LUCF) can be implemented to offset permanent emissions of carbon dioxide from the energy sector. Several approaches to accounting for carbon sequestration in LUCF projects have been proposed. In the present paper, the economic implications of adopting four of these approaches are evaluated in a normative context. The analysis is based on simulation of Australian farm–forestry systems. Results are interpreted from the standpoint of both investors and landholders. The role of baselines and transaction costs are discussed.  相似文献
