The original research question for this Biehl Internship was, “How does Cuba provide healthy, locally-produced food to the public with minimal inputs and environmental impact?” Through interviews of Cubans involved in urban agriculture, the study would explore how technology, research, policy, social norms, and collective decision-making contribute to the country’s local food movement. The inte...

They imparted a value for individuals, the importance of humility, an enthusiasm for sharing knowledge, and an appreciation of history. Photo: Kellie K. Magill. fi eld, and poorer countries could also develop their own biotechnology approaches. This more democratic approach to agro-biotech could conceivably gain back some of the trust that giant companies like Monsanto and DuPont lost in the GM...

The idea of network is employed across the social sciences though hardly with analytical unanimity. At one level, it is used as a simple descriptive template cast over empirical phenomena. At another, it is given greater explanatory power with at least meso-systemic implications. Far stronger analytical claims are made when it is mobilised to generate a systematic morphological account of conte...

Older adults constitute a rapidly growing demographic segment, but stereotypes persist about their consumer behavior. Thus, a more considered understanding of age-associated changes in decision making and choices is required. Our underlying theoretical model suggests that ageassociated changes in cognition, affect, and goals interact to differentiate older consumers’ decision-making processes, ...

but go on eating all the grass they get and much of the corn until at last they die, without pain.” But Evans believed he had microscopic evidence of a bloodborne pathogen responsible for the disease. WIth no facilities for staining pathogens — an art still in its infancy — a temperature of 28oC in the shade and hordes of flies, work with the microscope must have been exasperating. However, Eva...

Extraction of oil from Canadian tar sands is becoming increasingly contentious as it is claimed the process is one of the highest in terms of greenhouse gas emissions. But now, along with environmental campaigners, some shareholders in the companies that mine and fund tar sand oil are beginning to protest at the activity. British companies spearheading the drive to exploit the Canadian tar sand...

BPD is a disorder of many aspects, levels, meanings, presenting symptoms and issues. It demands deconstruction so that the blueprint of its development can provide a model for its treatment. Deconstruction can only be accomplished theoretically. This paper attempts to provide a theoretical perspective on both the development of the syndrome and a possible view of its treatment. The paper review...

Silica ferric hydrogensulfate is an efficient heterogeneous catalyst for the cyclization of 2- aminochalcones to the corresponding 2,3-dihydroquinolin- 4(1H)-ones. This intramolecular aza Michael reaction was carried out in high yields using chalcones bearing of electron donating and electron withdrawing groups. The catalyst is reusable without significant decreases in its activity after four t...
