DEVELOPMENT AND POVERTY REDUCTION: DO INSTITUTIONS MATTER? A STUDY ON THE IMPACT OF LOCAL INSTITUTIONS IN RURAL INDIA
The paper examines the impact of local institutions on development and poverty in the rural areas of India. Recent research on the role of institutions on the path of economic development indicates the importance of both "macro" and "micro" institutions including local institutions. The study finds a large number of both formal and informal local institutions in the surveyed villages, and a substantial degree of interaction of the households with the institutions. These include both formal institutions such as service cooperatives and dairy cooperatives, as well as informal institutions such as savings groups, community associations and labour groups. The study finds that apart from the standard factors included such as land, capital and labour, the presence and membership in local institutions plays a significant role in explaining the variation in household incomes and gain in capital assets over time. Savings/ micro-credit groups, and dairy cooperatives are found to be particularly important. Further, membership in these institutions is not found to be related to high asset levels or high caste - it is often inversely so. This indicates a stronger developmental role. Recorded opinions of the households supports the findings on the impact and beneficial role of local institutions. The study confirms that institutions do matter, and that local institutions can and do make a significant contribution in helping development in the rural areas, especially so for the lower income groups.Institutions, development, poverty reduction, International Development,

Reference hydrologic networks II: using reference hydrologic networks to assess climate-driven changes in streamflow
Reference hydrologic networks (RHNs) can play an important role in monitoring for changes in the
hydrological regime related to climate variation and change. Currently, the literature concerning hydrological
response to climate variations is complex and confounded by the combinations of many methods of analysis,
wide variations in hydrology, and the inclusion of data series that include changes in land use, storage regulation
and water use in addition to those of climate. Three case studies that illustrate a variety of approaches to the
analysis of data from RHNs are presented and used, together with a summary of studies from the literature, to
develop approaches for the investigation of changes in the hydrological regime at a continental or global scale,
particularly for international comparison. We present recommendations for an analysis framework and the next
steps to advance such an initiative. There is a particular focus on the desirability of establishing standardized
procedures and methodologies for both the creation of new national RHNs and the systematic analysis of data
derived from a collection of RHNs
Limited antigenic diversity of Plasmodium falciparum apical membrane antigen 1 supports the development of effective multi-allele vaccines
BackgroundPolymorphism in antigens is a common mechanism for immune evasion used by many important pathogens, and presents major challenges in vaccine development. In malaria, many key immune targets and vaccine candidates show substantial polymorphism. However, knowledge on antigenic diversity of key antigens, the impact of polymorphism on potential vaccine escape, and how sequence polymorphism relates to antigenic differences is very limited, yet crucial for vaccine development. Plasmodium falciparum apical membrane antigen 1 (AMA1) is an important target of naturally-acquired antibodies in malaria immunity and a leading vaccine candidate. However, AMA1 has extensive allelic diversity with more than 60 polymorphic amino acid residues and more than 200 haplotypes in a single population. Therefore, AMA1 serves as an excellent model to assess antigenic diversity in malaria vaccine antigens and the feasibility of multi-allele vaccine approaches. While most previous research has focused on sequence diversity and antibody responses in laboratory animals, little has been done on the cross-reactivity of human antibodies.MethodsWe aimed to determine the extent of antigenic diversity of AMA1, defined by reactivity with human antibodies, and to aid the identification of specific alleles for potential inclusion in a multi-allele vaccine. We developed an approach using a multiple-antigen-competition enzyme-linked immunosorbent assay (ELISA) to examine cross-reactivity of naturally-acquired antibodies in Papua New Guinea and Kenya, and related this to differences in AMA1 sequence.ResultsWe found that adults had greater cross-reactivity of antibodies than children, although the patterns of cross-reactivity to alleles were the same. Patterns of antibody cross-reactivity were very similar between populations (Papua New Guinea and Kenya), and over time. Further, our results show that antigenic diversity of AMA1 alleles is surprisingly restricted, despite extensive sequence polymorphism. Our findings suggest that a combination of three different alleles, if selected appropriately, may be sufficient to cover the majority of antigenic diversity in polymorphic AMA1 antigens. Antigenic properties were not strongly related to existing haplotype groupings based on sequence analysis.ConclusionsAntigenic diversity of AMA1 is limited and a vaccine including a small number of alleles might be sufficient for coverage against naturally-circulating strains, supporting a multi-allele approach for developing polymorphic antigens as malaria vaccines
Bicontinuous minimal surface nanostructures for polymer blend solar cells
This paper presents the first examination of the potential for bicontinuous structures such as the gyroid structure to produce high efficiency solar cells based on conjugated polymers. The solar cell characteristics are predicted by a simulation model that shows how the morphology influences device performance through integration of all the processes occurring in organic photocells in a specified morphology. In bicontinuous phases, the surface de. ning the interface between the electron and hole transporting phases divides the volume into two disjoint subvolumes. Exciton loss is reduced because the interface at which charge separation occurs permeates the device so excitons have only a short distance to reach the interface. As each of the component phases is connected, charges will be able to reach the electrodes more easily. In simulations of the current-voltage characteristics of organic cells with gyroid, disordered blend and vertical rod (rods normal to the electrodes) morphologies, we find that gyroids have a lower than anticipated performance advantage over disordered blends, and that vertical rods are superior. These results are explored thoroughly, with geminate recombination, i.e. recombination of charges originating from the same exciton, identified as the primary source of loss. Thus, if an appropriate materials choice could reduce geminate recombination, gyroids show great promise for future research and applications
Star formation history, double degenerates and type Ia supernovae in the thin disc
We investigate the relation between the star formation history and the
evolution of the double-degenerate (DD) population in the thin disc of the
Galaxy, which we assume to have formed 10 Gyr before the present. We introduce
the use of star-formation contribution functions as a device for evaluating the
birth rates, total number and merger rates of DDs. These contribution functions
help to demonstrate the relation between star-formation history and the current
DD population and, in particular, show how the numbers of different types of DD
are sensitive to different epochs of star formation.
We have compared the impact of different star-formation models on the rates
and numbers of DDs and on the rates of type Ia (SNIa) and core-collapse
supernovae (ccSN). In addition to a quasi-exponential decline model, we
considered an instantaneous (or initial starburst) model, a constant-rate
model, and an enhanced-rate model. All were normalised to produce the present
observed star density in the local thin disc. The evolution of the rates and
numbers of both DDs and SNIa are different in all four models, but are most
markedly different in the instantaneous star-formation model, which produces a
much higher rate than the other three models in the past, primarily as a
consequence of the normalisation.
Predictions of the current SNIa rate range from ~2 to 5\times10^{-4} yr^{-1}
in the four models, and are slightly below the observed rate because we only
consider the DD merger channel. The predicted ccSN rate ranges from 1.5 to 3
century^{-1}, and is consistent with observations.Comment: 11 pages, 16 figures, accepted for publication in MNRA
