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

Along with other affective and emotional dimensions, passion is at the heart of entrepreneurship. Yet past research on entrepreneurial passion (EP) has been hindered by the lack of a sound measurement instrument. Through a series of empirical studies conducted with samples from relevant populations, we develop and validate an instrument to capture EP and its inherent dimensions. We show that the task-specific dimensions of EP (intense positive feelings toward the domains of inventing, founding and developing, and the centrality of these domains to entrepreneurs' self-identity) are conceptually and empirically distinct from one another, and from other emotions and cognitions known to play a role in entrepreneurship. Our theory and results indicate that proper measurement of entrepreneurial passion incorporates the interaction between entrepreneurs' feelings and identity centrality for each domain. We discuss the implications of our model, instrument and findings for future research on the affective components of innovation and entrepreneurship. We also develop specific guidelines for using our validated instrument in future research. 相似文献

Discussed here are a number of drug abuse and drug testing issues. This article presents an overview of current developments in the area of drug testing in the workplace. There is an analysis of legislation, federal and state court decisions, and key legal arguments. These decisions and arguments are discussed in the context of employee rights and responsibilities. Also presented are the legal and ethical aspects of drug testing in the workplace. The authors make a case for a rehabilitative rather than a punitive approach to employee drug abuse. 相似文献

This study examines the relationship between profitability measures and management of ongoing liquidity needs for a large cross-section of firms over a twenty-year period. Long-run equilibrium relationships between the cash conversion cycle, a measure of ongoing liquidity management, and alternative measures of profitability are tested using both nonparametric and multiple regression analysis. Industry and size differences are controlled. While there are exceptions to the general finding for specific firms and for specific industries, the paper offers strong evidence that aggressive working-capital policies enhance profitability. 相似文献
