Using historical data from Nepal—one of the largest recipients of aid among South Asian countries—this paper investigates the link between foreign aid, growth, remittances and carbon dioxide (CO2) emissions. The investigation of this issue is particularly important, as policy makers in the least developed countries are increasingly concerned about growing reliance on energy imports, particularly fossil fuels, and increasing CO2 emissions. Mounting energy consumption has not only made their economies vulnerable to environmental disasters and increased health costs, but also to external shocks due to frequent fluctuations in international market prices for petroleum products. Since available studies are largely based on cross-sectional data—which lump together countries with different characteristics— empirical evidence is contradictory. In-depth case studies of countries with different backgrounds would certainly provide better insights into the link between aid, growth, remittances and CO2 emissions, and contribute to ongoing policy dialogue. Our empirical results, based on an in-depth case study of Nepal, suggest that more foreign aid and remittances reduce CO2 emissions, whereas financial development and higher income increase CO2 emissions. These findings point to the importance of market mechanisms for regulating financial development and higher income to control CO2 emissions, without undermining competitiveness.

BACKGROUNDThe paper examines the effect of child labour on child health outcomes in Bangladesh, advancing the methodologies and the results of papers published in different journals. OBJECTIVEWe examine the effect of child labour on child health outcomes. METHODSWe used Bangladesh National Child Labour Survey data for 2002-2003 for our analysis. RESULTSThe main finding of the paper suggests that child labour is positively and significantly associated with the probability of being injured or becoming ill. Intensity of injury or illness is significantly higher in construction and manufacturing sectors than in other sectors. Health disadvantages for different age groups are not essentially parallel. CONCLUSIONSThe results obtained in this paper strengthen the need for stronger enforcement of laws that regulate child labour, especially given its adverse consequences on health. Although the paper focuses on Bangladesh, much of the evidence presented has implications that are relevant to policymakers in other developing countries.

Adrenal growth occurs in experimental diabetes, and evidence exists for increased adrenal function. The concentration of PPRibP has been examined in the rat adrenal gland at various times after induction of diabetes with STZ, in view of the key role it plays in the synthesis of Purs and Pyrs. The PPRibP level was exceptionally high in the adrenal gland and increased faster than the rate of growth during the initial rapid growth phase--the first 7 days after STZ was given; PPRibP synthetase showed a parallel increase. Formation of R5P via the oxidative and nonoxidative segments of the PPP also was measured. The oxidative enzymes, G-6-PD and 6-PGD, increased in parallel with growth during the early phase, but showed a more marked rise during the secondary, slower, growth phase seen 6 wk after STZ was given, when this may be associated with the known sustained rise in plasma corticosteroids. The nonoxidative enzymes of the PPP, an alternate route for the production of R5P, showed smaller changes. The specifically high adrenal concentration of PPRibP may be related to the high Km for PPRibP (250 microM) of the first enzyme of the de novo pathway of Pur synthesis, as such synthesis may be required in the rat to replace the net loss of ATP associated with catecholamine secretion. Factors controlling PPRibP synthetase and their potential relative importance in the adrenal gland have been considered.

Negative Duffy expression on the surface of human red blood cells was believed to be a barrier for Plasmodium vivax infection in most Africans. However, P. vivax has been demonstrated to infect Duffy-negative individuals in several Central and East African countries. In this study, we investigated the distribution of Duffy blood group phenotypes with regard to P. vivax infection and parasitemia in Sudan. Out of 992 microscopic-positive malaria samples, 190 were identified as P. vivax positive infections. Among them, 186 were P. vivax mono-infections and 4 were mixed P. vivax and Plasmodium falciparum infections. A subset of 77 samples was estimated with parasitemia by quantitative real-time PCR. Duffy codons were sequenced from the 190 P. vivax positive samples. We found that the Duffy Fy(a-b+) phenotype was the most prevalent, accounting for 67.9% of all P. vivax infections, while homozygous Duffy-negative Fy(a-b-) accounted for 17.9% of the P. vivax infections. The prevalence of infection in Fy(a-b+) and Fy(a+b-)were significantly higher than Fy(a-b-) phenotypes (p = 0.01 and p < 0.01, respectively). A significantly low proportion of P. vivax infection was observed in Duffy negative individuals Fy(a-b-). This study highlights the prevalence of P. vivax in Duffy-negatives in Sudan and indicates low parasitemia among the Duffy-negative individuals.
