Cognitive Grammar offers a radical alternative to mainstream linguistic theories. This book introduces the theory in clear, non-technical language, relates it to current debates about the nature of linguistic knowledge, and applies it to in-depth analyses of a range of topics in semantics, syntax, morphology, and phonology. Study questions and suggestions for further reading accompany each of the main chapters.
In the United States, interest in urban agriculture has grown dramatically. While community gardens have sprouted across the landscape, home food gardens—arguably an ever-present, more durable form of urban agriculture—have been overlooked, understudied, and unsupported by government agencies, non-governmental organizations, and academics. In part a response to the invisibility of home gardens, this paper is a manifesto for their study in the Global North. It seeks to develop a multi-scalar and multidisciplinary research framework that acknowledges the garden’s social and ecological (...) or material dimensions. Given the lack of existing research, we draw on the more extensive literature on home gardens in the South and community gardens in the North to develop a set of hypotheses about the social-ecological effects of urban home food gardens in the North. These gardens, we hypothesize, contribute to food security, community development, cultural reproduction, and resilience at multiple scales; conserve agrobiodiversity; and support urban biodiversity. They may also have negative ecological effects, such as stormwater nutrient loading. Because of the entanglement of the social and the ecological or material in the garden, we review three theoretical perspectives—social ecological systems theory, actor-network theory, and assemblage theory—that have been or could be applied to the multi-scalar and multidisciplinary study of the garden. We also review sampling and analytic methods for conducting home garden research. The paper concludes with a discussion of opportunities to extend the research agenda beyond descriptive analysis, the primary focus of garden research to date. (shrink)
In the Aharonov- Bohm effect, electromagnetic potentials alter the two-slit interference pattern formed by an electron beam. We discuss here a curious feature of this effect, namely that, even though the interference pattern changes, none of its moments are shifted.
