Evaluation of Genetic Diversity and Heritability of Some Rapeseed (Brassica Napus) Genotypes Using Agronomical and Molecular Traits

High level of heritability and variability were estimated for all traits among genotypes. The genetic similarity of nine genotypes Brassica napus was estimated by random amplified polymorphic DNA (RAPD), which ranged from 69% to 94%. The phylogenetic tree resulted in two different clusters; the first including two genotypes which also showed high similarity in agronomic traits and the second included the rest of the genotypes. The genetic diversity was discussed in relation to molecular and agronomical traits. High and positive correlation were recorded for all traits. The high coupled of heritability and variability is considered as a powerful source for the selection of donors in the breeding program, where the genetic gain depends on the availability of genetic variation and high heritability

Growth recovery and faltering through early adolescence in low- and middle-income countries: Determinants and implications for cognitive development

Child chronic undernutrition, as measured by stunting, is prevalent in low- and middle-income countries and is among the major threats to child development. While stunting and its implications for cognitive development have been considered irreversible beyond early childhood there is a lack of consensus in the literature on this, as there is some evidence of recovery from stunting and that this recovery may be associated with improvements in cognition. Less is known however, about the drivers of growth recovery and the aspects of recovery linked to cognitive development. In this paper we investigate the factors associated with growth recovery and faltering through age 12 years and the implications of the incidence, timing, and persistence of post-infancy recovery from stunting for cognitive development using longitudinal data from Ethiopia, India, Peru, and Vietnam. We find that the factors most systematically associated with accelerated growth both before and after early childhood and across countries include mother's height, household living standards and shocks, community wages, food prices, and garbage collection. Our results suggest that post-infancy recovery from stunting is more likely to be systematically associated with higher achievement scores across countries when it is persistent and that associations between growth trajectories and cognitive achievement in middle childhood do not persist through early adolescence across countries. Overall, our findings indicate that growth after early childhood is responsive to changes in the household and community environments and that growth promotion after early childhood may yield improvements in child cognitive development

Socio-economic assessement of farmers' vulnerability as water users subject to global change stressors in the hard rock area of southern India. The SHIVA ANR project

International audienceDemand for vulnerability assessments is growing in policy-making circles, to support the choice of appropriate measures and policies to reduce the vulnerability of water users and resources. Through the SHIVA ANR project, we are seeking a method to assess and map the vulnerability of farmers in southern India to both climate and socioeconomic changes, and secondly, to assess the costs and benefits associated with trends farmers' vulnerability in the medium and long-term. The project is focusing on southern India 's hard rock area, as in the geological context, both surface and ground water resources are naturally limited. We are also focusing on farming populations as these are the main water users in the area and rely exclusively on groundwater. The area covers southern India's semi-arid zone, where the rainfall gradient ranges from 600 mm to 1100 mm. Vulnerability is expected to vary according to local climatic conditions but also the socioeconomic characteristics of farming households. The SHIVA research team has been divided into six thematic groups in order to address the different scientific issues : downscaling the regional climate scenario, farm area projections, vulnerability assessments and quantification, vulnerability mapping, hydrological modelling and upscaling, and vulnerability impact assessements. Our approach is multidisciplinary to cater for for numerous inherent themes, and integrated to cater for vulnerability as a dynamic and multidimensional concept. The project 's first results after 10 months of research are presented below

ORGANIZATION, POVERTY AND WOMEN: Andhra Pradesh in Global Perspective

WP 2011-13 April 201

Siblings, schooling, work and drought

In this paper we explore the effect that a recent drought in Andhra Pradesh, India, has had on the school and work patterns of children aged 11 to 12 years. Previous empirical studies have investigated the effect of shocks on outcomes for children but few have allowed for heterogeneous treatment effects across children. Ignoring such heterogeneity might lead to biases in the estimated impact of the shocks. The aim of this paper is to address this lacuna. Using data from Young Lives, a longitudinal cohort study of children, we estimate the average impact of the drought on participation in schooling. We then expand our empirical model to allow for heterogeneous effects across children of different demographic categories – namely gender and birth order. Our analysis shows that ignoring child heterogeneity would underestimate the severity of the effect of the drought on children’s welfare and human capital accumulation. In particular, we find that the drought significantly reduced the time spent on schooling by most demographic groups. The exception is the group most likely to have been involved in agricultural work when there is no drought; the schooling participation of eldest sons appears to increase because of the drought. Furthermore, we trace the impact of the drought on child labour and cognitive development, while we rule out the possibility that the uncovered heterogeneous patterns might be driven by social norms or cultural biases in favour of eldest sons.© Young Lives 2011.

Analysing Bank Productivity Using Malmquist Approach: A Case of Karnataka and Undivided Andhra Pradesh Regional Rural Banks (RRBs)

The paper endeavours to analyse the intertemporal variations in total factor productivity (TFP) in regard to financial efficiency and financial inclusion among the Regional Rural Banks (RRBs) in Karnataka and undivided Andhra Pradesh (AP) across the period of their amalgamation (1999-2011). Considering suitable proxies for financial efficiency (FE) and financial inclusion (Incl) from the annual RRB balance sheet(s) data the TFP of „RRB‟s in regard to „financial efficiency‟ and „financial inclusion‟ across the period of their amalgamation were estimated using the data envelopment analysis (DEA) technique based FEAR programme in R. The findings of the study reveal that the impact on the RRB amalgamation on TFP has been largely indifferent in regard to financial efficiency and financial inclusion among the sample RRBs of Karnataka and Undivided AP. That such indifference could be attributed to the frequent, wavering state policy revisions over the 2000s in the norms pertaining to bank-intermediation in general, and priority sector lending in particular. Such revisions had virtually vitiated the prospects of sustainable branch-level lending for RRBs as evidenced from the negative correlations between technical efficiency (TE) scores in regard to financial efficiency and inclusion for certain years only in the post-amalgamation period as in case of Karnataka RRBs
