For most cities, the possibility of transforming unused property into community and city assets is as yet hypothetical. Fiscal constraints limit the amount of land acquisition, relocation, and demolition that cities can undertake. Private investors, unsure of which neighborhoods have a chance of becoming self-sustaining, are reluctant to take risks in untested markets. Cities need to create cit...

This paper sets up a two country monopolistic competition model with intra-industry trade to study the effects of an exogenous differential in wage and social policies on the location of industry. Two model scenarios are considered. In the traditional one with physical capital, such a differential induces a relocation effect which increases with the level of trade integration. The ‘new economic...

This paper analyses the dynamics of the informal economy in Cali Colombia. In particular it details the working lives and characteristics of street vendors in the main food market of the city, Santa Helena. It compares them with formal merchants in the same area and uncovers a major difference in income. Street vendors make more money. Government interventions to revitalize the area and create ...

We empirically investigate the use of relocation operator as a local search operator, in combination with genetic search, in a Tree Adjoining Grammar Guided Genetic Programming system (TAG3P). The results show that, on all the problems we tried, the use of the relocation operator as a local search operator in TAG3P outperforms TAG3P using purely crossover and mutation, and also outperforms stan...

This thesis is about wireless multi-hop networks such as wireless sensors networks or hybrid sensor/actuator networks and actuator networks. Those kinds of networks are composed of independent entities (nodes, i.e. the robots) which have very limited computing and memory capabilities. Moreover, they are battery powered and have to work in an efficient way. They communicate through the radio med...

direct regenerations by using mature cotyledonary node as a explants has been shown to be time-saving and convenient strategy for micropropagation of soybean. so we have evaluated regeneration protocol through single shoot using cotyledonary node as a rapid and efficient protocol for two soybean cultivars and one mutant line. cotyledonary nodes explants obtained from 7-days-old in vitro seedlin...

Nonhuman primates from domestic sources constitute a small, but critical, proportion of animals studied in research laboratories. Many of these nonhuman primates are raised at one facility and subsequently transported/relocated to another facility for research purposes. We examined the effects of transport, relocation, and acclimation on the phenotype and function of peripheral blood mononuclea...
