An estimated 260 million indigenous peoples live in Asia. Most of them inhabit forested uplands where a large number of them practice shifting cultivation, which is also called as swidden cultivation or rotational farming. For them, shifting cultivation is not merely a technique of farming; it is their ways of life. Government policies and laws have attempted to limit or outright ban shifting c...

In a spatial thermal gradient, Caenorhabditis elegans migrates toward and then isothermally tracks near its cultivation temperature. A current model for thermotactic behavior involves a thermophilic drive (involving the neurons AFD and AIY) and cryophilic drive (involving the neuron AIZ) that balance at the cultivation temperature. Here, we analyze the movements of individual worms responding t...

Simplified cultivation technologies for rice have become increasingly attractive in recent years in China because of their social, economical and environmental benefits. To date, several simplified cultivation technologies, such as conventional tillage and seedling throwing (CTST), conventional tillage and direct seeding (CTDS), no-tillage and seedling throwing (NTST), no-tillage and direct see...

This visual essay in "The Photographer's Frame" explores how Americans’ love affair with road trips made a marriage of national park scenic landscapes and automobiles nearly inevitable—and has helped, literally, drive climate change.

This paper describes the findings of an ethnomethodological enquiry into the work of graphic designers. We explore the collaborative nature of graphic design as undertaken by a small team of designers working in a packaging design company. In doing so, we attempt to explicate the way in which practice, talk and technology are intricately bound up in such a way as to constitute a creative proces...
