Children are sensitive to a number of considerations influencing distributions of resources, including equality, equity, and reciprocity. We tested whether children use a specific type of reciprocity norm—market norms—in which resources are distributed differentially based strictly on amount offered in return. In two studies, 195 children 5–10 years and 60 adults distributed stickers to friends offering same or different amounts of money. Overall, participants distributed more equally when offers were the same and more unequally when offers were different. Although sensitive to why friends offered different amounts of money, children increasingly incorporated market norms into their distributions with age, as the oldest children and adults distributed more to those offering more, irrespective of the reasons provided. 相似文献

ABSTRACTThis forum brings together food, (in)security, and communication. The authors participating in this forum center communication as both process and tool for understanding, mitigating, and making meaning of food (in)security. The nine authors together discuss the role of communication in food (in)security, the central challenges for scholars and practitioners working on food (in)security, and the creative possibilities and impacts influencing the future of food (in)security. The forum produces a call for applied scholars to re-imagine communication frameworks in order to make meaningful differences in their communities. 相似文献

The problem of student indiscipline is an issue of concern for teachers and parents around the world. Teachers need to maintain student discipline and for them to do so it is important that they also understand the nature of discipline problems. This study, by Lawrence Kofi Ametepee, who is studying for a PhD in special education, Morgan Chitiyo, board certified behaviour analyst and Assistant Professor of Special Education, both at Southern Illinois University, Carbondale, USA, and Susan Abu, who is currently a graduate student in the Department of Women's Studies at Texas Women's University, was designed to examine the nature and perceived causes of student indiscipline in Zimbabwean secondary schools. The authors anticipate that such an examination will promote teachers’, parents’ and policy makers’ understanding of student indiscipline, which will, in turn, enhance disciplinary policies and practices, making schools safer for all students and more effective in their role as educational and socialising agents. 相似文献
