Location decisions and nongovernmental organization motivation : evidence from rural Bangladesh

Nongovernmental organizations (NGOs) play an increasingly important role in development assistance, but little systematic evidence is available about their objectives and choices in developing countries. The authors develop two stylized accounts of NGO motivation: one in which donor contracts determine location decisions, and another in which altruistic motivations are the principal determinants. The authors then use data from the 1995 and 2000 rounds of the Bangladesh Households and Income and Expenditure Survey to analyze location decisions of NGO programs established between those two sample years. The data show that net change in a community's NGO program was unrelated to the community's need and that NGOs were ready to establish new programs in new areas without being concerned of duplicating the efforts of other NGOs. The findings suggest that contracts with donors, implicit or explicit, probably play a crucial role in determining the incentives that affect NGO program location choices.Poverty Monitoring&Analysis,Insurance&Risk Mitigation,ICT Policy and Strategies,Poverty Impact Evaluation,Agricultural Knowledge&Information Systems,Poverty Monitoring&Analysis,Agricultural Knowledge&Information Systems,ICT Policy and Strategies,Non Governmental Organizations,Community Development and Empowerment

The Role of DmCatD, a Cathepsin D-Like Peptidase, and Acid Phosphatase in the Process of Follicular Atresia in Dipetalogaster maxima (Hemiptera: Reduviidae), a Vector of Chagas' Disease

In this work, we have investigated the involvement of DmCatD, a cathepsin D-like peptidase, and acid phosphatase in the process of follicular atresia of Dipetalogaster maxima, a hematophagous insect vector of Chagas' disease. For the studies, fat bodies, ovaries and hemolymph were sampled from anautogenous females at representative days of the reproductive cycle: pre-vitellogenesis, vitellogenesis as well as early and late atresia. Real time PCR (qPCR) and western blot assays showed that DmCatD was expressed in fat bodies and ovaries at all reproductive stages, being the expression of its active form significantly higher at the atretic stages. In hemolymph samples, only the immunoreactive band compatible with pro-DmCatD was observed by western blot. Acid phosphatase activity in ovarian tissues significantly increased during follicular atresia in comparison to pre-vitellogenesis and vitellogenesis. A further enzyme characterization with inhibitors showed that the high levels of acid phosphatase activity in atretic ovaries corresponded mainly to a tyrosine phosphatase. Immunofluorescence assays demonstrated that DmCatD and tyrosine phosphatase were associated with yolk bodies in vitellogenic follicles, while in atretic stages they displayed a different cellular distribution. DmCatD and tyrosine phosphatase partially co-localized with vitellin. Moreover, their interaction was supported by FRET analysis. In vitro assays using homogenates of atretic ovaries as the enzyme source and enzyme inhibitors demonstrated that DmCatD, together with a tyrosine phosphatase, were necessary to promote the degradation of vitellin. Taken together, the results strongly suggested that both acid hydrolases play a central role in early vitellin proteolysis during the process of follicular atresia.Fil: Leyria, Jimena.

Rising Food Prices and Household Welfare: Evidence from Brazil in 2008

Food price inflation in Brazil in the twelve months to June 2008 was 18 percent, while overall inflation was 5.3 percent. This paper uses spatially disaggregated monthly data on consumer prices and two different household surveys to estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage-earning agricultural labor force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. While the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, the market income effect was positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U-shaped, with the middle-income groups suffering larger proportional losses than the very poor. Nevertheless, since Brazil is 80 percent urban, higher food prices still led to a greater incidence and depth of poverty at the national level.food prices, welfare, poverty, inequality, price change incidence curve, Brazil

Rising food prices and household welfare : evidence from Brazil in 2008

Food price inflation in Brazil in the twelve months to June 2008 was 18 percent, while overall inflation was seven percent. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage-earning agricultural labor force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. While the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, the market income effect was positive and progressive, particularly in rural areas.
