James Anderson's Political Economy--His Influence on Smith and Malthus

James Anderson's powerful critique of Adam Smith's position on the corn export bounty was published in 1777. It focuse d on Smith's proposition that the bounty could not lead to increased corn production because it could not increase corn's real price. Smit h's response to the critique is traced in later editions of Wealth of Nations. While Anderson's critique of Smith influenced Thomas Malthu s's writings from 1803 onwards, his theory of differential rent did n ot influence Malthus at this stage. An examination of the evolution o f Malthus's ideas on rent between 1803 and 1815, however, indicates t hat Malthus knew and used Anderson's work on rent.

Government intervention in a dynamic economy

From the late 1970s onwards, the view that government intervention could provide a means of overcoming market failure in advanced was increasingly questioned. For some, intervention was to be discouraged because it interfered with individual liberty. For others, what was problematic was the welfare economist's assumption of an autonomous state acting in the public interest. Finally, there was the issue of the state's ability to achieve what it set out to do. Government failure it was argued was just as pervasive as market failure and no antidote to it. This paper critically evaluates such arguments in relation to competition, industrial change, innovation, and competitive advantage in production.

Green photochemistry: photo-Friedel-Crafts acylations of 1,4-naphthoquinone in room temperature ionic liquids

The photo-Friedel-Crafts acylation of 1,4-naphthoquinone with various aldehydes was investigated in a series of room temperature ionic liquids. High conversions and selectivities were achieved in [C(2)mim](+)-based ionic liquids with the highest isolated yields found in [C(2)mim][NTf2]. The developed procedure allowed for a replacement of hazardous solvents such as benzene and acetonitrile which are commonly used for this transformation.

ZnO nanofluids: Green synthesis, characterization, and antibacterial activity

Zinc oxide nanoparticles have been synthesized by microwave decomposition of zinc acetate precursor using an ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide, [bmim][NTf2] as a green solvent. The structure and morphology of ZnO nanoparticles have been characterized using X-ray diffraction and transmission electron microscopy. The ZnO nanofluids have been prepared by dispersing ZnO nanoparticles in glycerol as a base fluid in the presence of ammonium citrate as a dispersant. The antibacterial activity of suspensions of ZnO nanofluids against (E. coli) has been evaluated by estimating the reduction ratio of the bacteria treated with ZnO. Survival ratio of bacteria decreases with increasing the concentrations of ZnO nanofluids and time. The results show that an increase in the concentrations of ZnO nanofluids produces strong antibacterial activity toward E. coli. (C) 2010 Elsevier B.V. All rights reserved.
