Lanthionine ketimine (LK) represents a poorly understood class of thioethers present in mammalian CNS. Previous work has indicated high-affinity interaction of LK with synaptosomal membrane protein(s), but neither LK binding partners nor specific bioactivities have been reported. In this study, LK was chemically synthesized and used as an affinity agent to(More)
This paper discusses findings made during a study of energy use feedback in the home (eco-feedback), well after the novelty has worn off. Contributing towards four important knowledge gaps in the research, we explore eco-feedback over longer time scales, focusing on instances where the feedback was not of lasting benefit to users rather than when it was.(More)
Emergency relief centres provide financial, housing, food and other types of support to families and individuals who experience financial hardship. These centres are non-profit, often government supported organizations that rely on the help of their volunteers and social workers.

Budgeting is an important means of controlling ones finances and reducing debt. This paper outlines our work towards designing more user centred technology for individual and household budgeting. Based on an ethnographically informed study with 15 participants, we highlight a misalignment between people's actual budgeting practices and those supported by(More)
Decreasing the incidence of nonmelanoma skin cancer (NMSC) is of great importance in regards to future healthcare services. Given the previously reported preventive effects of α-difluoromethylornithine (DFMO) in skin and colon cancer trials, we determined appropriate cause to update the clinical data on the subjects from the recently reported randomized,(More)
The hobby of collecting represents the passionate acquisition and possession of a specific type(s) of object; creating a 'spectacle', to be shared with others. The fundamentality of the physical objects in collections against the backdrop of the growing ubiquity of computing provides a unique and compelling avenue for design. Based on interviews with 11(More)
Understanding how families manage their finances represents a highly important research agenda given the recent economic climate of debt and uncertainty. To have a better understanding of the economics in domestic settings, it is very important to study the ways money and financial issues are collaboratively handled within families. Using an ethnographic(More)
The use of psychohistoriographic cultural therapy (PCT) developed in Jamaica is described in the context of two workshops in Montreal. PCT is a form of group intervention that seeks to elicit and clarify the "psychic centrality" of a group. Psychic centrality refers to a sense of psychological containment or organization of diverse individual points of view(More)
The research reported in this paper explores autonomous technologies for agricultural farming application and is focused on the development of multiple-cooperative agricultural robots (AgBots). These are highly autonomous, small, lightweight, and unmanned machines that operate cooperatively (as opposed to a traditional single heavy machine) and are suited(More)
