    IMPLICATIONS OF CAPITAL-INTENSIVE DEVELOPMENT INTERVENTIONS FOR COMMUNAL RESOURCE OWNERS: THE CASE OF COMMUNAL FARMERS IN ECUADOR

    Get PDF
    The introduction in Ecuador of a primary irrigation infrastructure into a communal setting where land users did not fully control the land and had effectively no access to credit, produced a sell off of nearly all irrigable lands. The change in land reservation prices between buyers and sellers is analyzed.Land Economics/Use,

    Economic evaluation of the spanish port system using the promethee multicriteria decision method

    Get PDF
    Due to legislation changes during the Nineties, the Spanish Port System has gone through a series of changes that, simultaneous with a period of economic expansion and generalized marine traffic growth, have affected the Port System鈥檚 composition, organization and operation. The gradual transformations produced by this context, give shape to a new model of operation for Port Authorities, which now start to be managed under business criteria and procedures of functional autonomy, competition, effectiveness and profit, moving away from State dependency, and at the same time allowing greater participation of regional governments. As a result, general purpose Spanish ports develop their activity in a very competitive market, where self financing and financial sufficiency prevail as high-priority management goals. Our work considers these circumstances from the approach offered by multiple objective decision models, in order to study the performance evolution of Port Authorities, using certain ratios with economic meaning which will allow determining how their relative ranking within the national set has varied. The great variety of available business ratios and the different concepts to analyze give the problem a discrete multicriteria dimension. Thus we have chosen the Promethee method for our analysis, given its results simplicity and easy understanding for the decision agent, the economic interpretation of its parameters, and the stability of its results. In addition, scale effects between different alternatives are eliminated, allowing the possibility of incomparability among them and offering a sensitivity analysis of the effects.

    Effects of Copper and/or Cholesterol Overload on Mitochondrial Function in a Rat Model of Incipient Neurodegeneration

    Copper (Cu) and cholesterol (Cho) are both associated with neurodegenerative illnesses in humans and animals models. We studied the effect in Wistar rats of oral supplementation with trace amounts of Cu (3鈥塸pm) and/or Cho (2%) in drinking water for 2 months. Increased amounts of nonceruloplasmin-bound Cu were observed in plasma and brain hippocampus together with a higher concentration of ceruloplasmin in plasma, cortex, and hippocampus. Cu, Cho, and the combined treatment Cu + Cho were able to induce a higher Cho/phospholipid ratio in mitochondrial membranes with a simultaneous decrease in glutathione content. The concentration of cardiolipin decreased and that of peroxidation products, conjugated dienes and lipoperoxides, increased. Treatments including Cho produced rigidization in both the outer and inner mitochondrial membranes with a simultaneous increase in permeability. No significant increase in Cyt C leakage to the cytosol was observed except in the case of cortex from rats treated with Cu and Cho nor were there any significant changes in caspase-3 activity and the Bax/Bcl2 ratio. However, the A尾(1鈥42)/(1鈥40) ratio was higher in cortex and hippocampus. These findings suggest an incipient neurodegenerative process induced by Cu or Cho that might be potentiated by the association of the two supplements.Fil: Arnal, Nathalie.
