185 Renormalization group equations and the Lifshitz point in noncommutative Landau-Ginsburg theoryA one-loop renormalization group (RG) analysis is performed for noncommutative Landau-Ginsburg theory in an arbitrary dimension. We adopt a modern version of the Wilsonian RG approach, in which a shell integration in momentum space bypasses the potential IR singularities due to UV-IR mixing. The mo...2002-02
186 Labor productivity and energy use in a three sector model: an application to EgyptThis paper presents a model of a developing economy with three sectors| industry, agriculture, and energy. Industry and energy are assumed to be demand- constrained, but agriculture supply-constrained. The model highlights (a) structural transformation, through labor transfer from agriculture to in...2010
187 Ends and means in conflictA great danger of our time is our intense preoccupation with the ends we seek, so much so that we have overlooked the effect, usually and perhaps always the determinative effect, that our choice of means will have made upon the nature of those ends. This problem is made more difficult in that our vi...Weapons proliferation; Arms race; Atomic weapons1988
188 Dynamic systems theory places the scientist in the systemDynamic systems theory is a way of describing the patterns that emerge from relationships in the universe. In the study of interpersonal relationships, within and between species, the scientist is an active and engaged participant in those relationships. Separation between self and other, scientist...2002

191 Innovation in human/social guiseIn this chapter, innovation is viewed from a step further back, as an astronaut might see the earth from space. It is not seen as something analysed as a linear, technical process, whether incremental or radical. Nor is it seen as a process in which social context adds to the mix of other factors to...Innovation; Social process2006
192 Careful what you ask for: reconsidering feminist epistemology and autobiographical narrative in research on sexual identity developmentFeminist theory has had an undoubtable but inconsistent influence on developmental psychology. Although feminist perspectives have productively challenged developmental models centered on male experiences (Gilligan 1982) and have called attention to socialization practices that reproduce systemati...Feminism; Epistemology; Autobiography2006
193 Spatial-temporal hierarchy of regional inequality of ChinaThis paper advances the multi-scale and multi-mechanism framework of regional inequality in China by using the most recent statistical data. We analyze the multi-scalar patterns of China's regional inequality with GIS and statistical techniques, and demonstrate the significance of the municipality e...Regional inequality; Spatial hierarchy; GIS2010-07
194 Teaching and learning combined (TLC)Most professors have to lean a LOT. Every day, it seems, there IS something that we need that we don't know. So what do you do to lean this new information? Perhaps you hit the Web or the library, find a tutorial, a textbook, or a paper, and give it a little reading time in between a 12:00 class an...2003
195 Zero temperature string breaking in lattice quantum chromodynamicsThe separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or ‘‘string,'' which should break in the presence of light quark-antiquark pairs. This expected zero-temperature phenomenon has proven elusive in simulations of lattice QCD. We study mixing between the ...String breaking; Wilson loop2001-09
196 Reaction-diffusion patterns in smart sensor networksWe introduced the use of Turing?s reaction-diffusion pattern formation to support high-level tasks in smart sensor networks (S-Nets).
