Adoption of O2O food delivery services in South Korea: The moderating role of moral obligation in meal preparation

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.     

Analyzing Food Science Research for Publishing Characteristics as a Model for Understanding the Needs of Researchers

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.
