The actions of prostaglandin (PG) E2 are mediated by four distinct classes of PGE2 E-prostanoid (EP) receptors (EP1 through EP4). However, the in vivo functions of the individual EP receptor subtypes have not been delineated. To study the functions of one of these subtypes, the EP3 receptor, we generated EP3-deficient (-/-) mice by gene targeting. EP3 -/-(More)
Global food, beverage and fibre markets can be characterised as networks of global value chains. Increasingly such chains are private and powerful, closely coordinated or fully vertically integrated, self-regulated, global and experience-based. The more that global agricultural and food product trade is conducted in these global value chains, the greater(More)

Abstract: Globalization results when markets become more integrated because of reduced transaction and transport costs. These costs have fallen because of sustained advances in(More)
This paper reports on an analysis of technical efficiency and varietal differences in pistachio production in Iran. A random sample of 475 farmers was selected from the province of Kerman in 2003 and 2004. In this study, farmers are classified into three groups according to the variety of tree they planted. The three main varieties of pistachio trees(More)
Intensive livestock systems differ from most pasture-based systems in that managers exert much greater control over the production cycle and the quality of animals entering the system. Consequently, technical inefficiencies among animals tend to be much more easily eradicated. Nevertheless, a range of factors could still cause both technical inefficiency(More)
There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function(More)
Most analyses of technical efficiency and productivity focus on the activities of firms or institutions using inputs to produce outputs. In this paper, we report the results of an efficiency analysis that is couched in a different context. We analyse the efficiency with which physical characteristics of individual lot-fed Australian beef cattle are combined(More)
The purpose of this paper is to examine the policy options with the best prospects to improve the performance and competitiveness of housewives' groups in the cottage food industry in Thailand. The analytical framework is based on an analysis of private and value chain-level net benefits from alternative policy actions and research and training initiatives.(More)
