From sharing food to sharing information

Food Sharing

Food sharing is a human universal trait that forms the centerpiece of economic and social life in hunter-gatherer societies. Human livelihoods require sharing at all life stages: to support infancy, childhood, and adolescence, and to help reduce risk of daily food shortfalls in adulthood. Attempts to understand the evolved human life history require an examination of the conditions that led to ...

Turning from Image Sharing to Experience Sharing

We sketch an argument that one way to facilitate this sense of “experience sharing” may be to place image sharing in an explicit conversational context. We further argu...

Food-Sharing Models

Food sharing is one of the most obvious forms of cooperation among hunter-gatherers and is intricately linked to the evolved human life history and foraging niche; it is also observed in other primates. Theoretical models of food sharing go back to the asymmetric Hawk–Dove game, wherein the individual who derives greater value from a resource should bemore willing to fight over it (Hawk), where...

Sharing @ The Edge: Secure Information Sharing

Peer-to-peer (P2P) computing promises to return the World Wide Web to an environment where the edge of the network is as important as the Web servers that have dominated its early years. This paper describes issues associated with P2P computing that must be solved before widespread deployment is possible. The paper presents a P2P solution where services and content are equally secured and can b...
