Most studies on O2O services have focused solely on the technological merits of mobile applications, overlooking the role of the value systems that underlie people’s lifestyles.In contrast, this research sheds light on how people’s value systems influence their decision to adopt food delivery applications. Particularly, it proposes that people’s moral obligation in meal preparation can change the mode of thinking that guides their adoption decision. Namely, moral obligation is assumed to restrict people from acting on their basic convenience orientation in meal preparation. Empirical results have supported this assumption by showing that people with a high moral obligation (or married people) are more reluctant to convert their basic convenience-seeking tendencies into actual adoption intention than those with a low moral obligation (or single people). The important theoretical and managerial implications of these results are also discussed.  相似文献

Abstract

This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced.  相似文献

在当前面点教学中,大部分教师仍处于凭经验教学阶段,各类教学品种无定量的工艺参数和明确的质量标准,不同教师做法不一,且计量手段落后,概念模糊,制品质量不稳定,造成学生学习起来难度较大;实施面点工艺标准化教学,可使学生更快更好的掌握烹饪工艺和技能,同时增强了学生的标准化意识,为传统食品的工业化生产打好基础;工艺标准化是通过对教学品种的制作工艺进行定量研究,从它的原料性状、制作工艺、营养卫生、质量标准及饮食美学等几个方面着手,确定原料质量标准、制作工艺标准和产品质量标准来实现的。  相似文献

ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.  相似文献

杜甫在草堂创作了大量的闲适诗。缘于长期的漂泊和草堂生活的相对安定,草堂诗呈现出与其他阶段迥然不同的艺术风格,写了大量饮食方面的诗。诗中大部分是从琐碎的生活中,去细细品味人生的乐趣,暂时放下不得志的苦闷,享受当下的自足与闲适的生活,有些诗中也蕴涵忧国思乡之情。  相似文献
