Targeting poverty in Laos: how well do current approaches reach the poor?

Funds for poverty reduction are limited, so allocating them effectively is important in development planning. A common way to do this is to plot the distribution of poor people on maps, and then to target poverty-alleviation efforts at areas with the largest incidences of poverty. But this is a crude approach that risks missing a large share of the poor. This issue of evidence for policy shows how careful analysis of detailed spatial information – in this case in Laos – can reveal patterns that are not immediately obvious. That can lead to better, more precise targeting well beyond a purely geographic focus on poor areas, and to more differentiated and spatially integrated development planning.

Social milieus and worldviews in Mamluk adab-encyclopedias: The example of poverty and wealth

The economic and cultural rise of parts of the ʿāmma due to the particular economic and infrastructural conditions of the Mamluk era fostered the emergence of new intermediate levels of literature that were situated between the literature of the elite and that of the utterly ignorant and unlettered populace, between the Arabic koiné (al-ʿarabīya al-fuṣḥā) and the local dialects (ʿāmmīya-s), between written and oral composition, performance and transmission. The paper proposes to analyze the composition of three Mamluk adab-encyclopedias and their treatment of poverty and wealth in light of the social milieus of their authors and publics.

NADPH oxidase-independent formation of extracellular DNA traps by basophils

Basophils are primarily associated with a proinflammatory and immunoregulatory role in allergic diseases and parasitic infections. Recent studies have shown that basophils can also bind various bacteria both in the presence and the absence of opsonizing Abs. In this report, we show that both human and mouse basophils are able to produce mitochondrial reactive oxygen species and to form extracellular DNA traps upon IL-3 priming and subsequent activation of the complement factor 5 a receptor or FcεRI. Such basophil extracellular traps (BETs) contain mitochondrial, but not nuclear DNA, as well as the granule proteins basogranulin and mouse mast cell protease 8. BET formation occurs despite the absence of any functional NADPH oxidase in basophils. BETs can be found in both human and mouse inflamed tissues, suggesting that they also play a role under in vivo inflammatory conditions. Taken together, these findings suggest that basophils exert direct innate immune effector functions in the extracellular space.

Impaired DNase1-mediated degradation of neutrophil extracellular traps is associated with acute thrombotic microangiopathies.

BACKGROUND Acute thrombotic microangiopathies (TMAs) are characterized by excessive microvascular thrombosis and are associated with markers of neutrophil extracellular traps (NETs) in plasma. NETs are composed of DNA fibers and promote thrombus formation through the activation of platelets and clotting factors. OBJECTIVE The efficient removal of NETs may be required to prevent excessive thrombosis such as in TMAs. To test this hypothesis, we investigated whether TMAs are associated with a defect in the degradation of NETs. APPROACH AND RESULTS We show that NETs generated in vitro were efficiently degraded by plasma from healthy donors. However, NETs remained stable after exposure to plasma from TMA patients. The inability to degrade NETs was linked to a reduced DNase activity in TMA plasma. Plasma DNase1 was required for efficient NET-degradation and TMA plasma showed decreased levels of this enzyme. Supplementation of TMA plasma with recombinant human DNase1 restored NET-degradation activity. CONCLUSIONS Our data indicates that DNase1-mediated degradation of NETs is impaired in patients with TMAs. The role of plasma DNases in thrombosis is, as of yet, poorly understood. Reduced plasma DNase1 activity may cause the persistence of pro-thrombotic NETs and thus promote microvascular thrombosis in TMA patients. This article is protected by copyright.

A different perspective on poverty in Lao PDR: Multidimensional poverty in Lao PDR for the years 2002/2003 and 2007/2008

This paper presents an indicator for measuring multidimensional poverty in the Lao People’s Democratic Republic applying the Alkire–Foster methodology to the Lao Expenditure and Consumption Survey 2002/2003 and 2007/2008. We calculated a multidimensional poverty index (MPI) that includes three dimensions: education, health, and standard of living. Making use of the MPI’s decomposability, we analyse how much each of the different dimensions and its respective indicators contribute to the overall MPI. We find a marked reduction in the multidimensional poverty headcount ratio over the study period, regardless of how the indicators are weighted or how the deprivation and poverty cut-offs are set. This reduction is based on improvements regarding all indicators except cooking fuel and nutrition. We observe no significant reduction in the intensity of poverty, however; there are wide disparities between the country’s regions and between urban and rural areas. The proportion of poor people in rural areas is more than twice as high as that in urban areas. By complementing the traditional income-based poverty measure, we hope to provide useful information that can support knowledge-based decision-making for poverty alleviation.

How political economies affect immigrants' socio-economic incorporation. A comparative analysis of immigrants’ poverty risks across advanced industrialised countries

Immigration and the resulting increasing ethnic diversity have become an important characteristic of advanced industrialised countries. At the same time, the majority of the countries in question are confronted with structural transformation such as deindustrialisation and changes in family structures as well as economic downturn, which limit the capacities of nation-states in addressing rising inequality and supporting those individuals at the margins of the society. This paper addresses both issues, immigration and inequality, by focusing on immigrants’ socio-economic incorporation into the receiving societies of advanced industrialised countries. The aim of this paper is to explain cross-national variation in immigrants’ poverty risks. Drawing on the political economy as well as the migration literature, the paper develops a theoretical framework that considers how the impact of the national labour market and welfare system on immigrants’ poverty risks is moderated by the integration policies, which regulate immigrants’ access to the labour market and social programs (or immigrants’ economic and social rights). The empirical analysis draws on income surveys as well as a newly collected data set on economic and social rights of immigrants in 19 advanced industrialised countries, including European countries as well as Australia, and North America, for the year 2007. As the results from multilevel analysis show, integration policies concerning immigrants’ access to the labour market and social programs can partly explain cross-national variations in immigrants’ poverty risks. In line with the hypothesis, stricter labour market regulations such as minimum wage setting reduce immigrants’ poverty risks stronger in countries where they are granted easier access to the labour market. However, concerning the impact of more generous social programs the reductive poverty effect is stronger in countries with less inclusive access of immigrants to social programs. The paper concludes by discussing possible explanations for this puzzling finding.

The Basement of the Deccan Traps and Its Madagascar Connection: Constraints from Xenoliths

Paleogeographic reconstructions of India and Madagascar before their late Cretaceous rifting juxtapose the Antongil Block of Madagascar against the Deccan Traps of India, indicating that the Western Dharwar Craton extends below the Deccan lavas. Some recent studies have suggested that the South Maharashtra Shear Zone along the northern Konkan coast of India limits the northern extent of the Western Dharwar Craton, implying that the craton does not extend below the Deccan Traps, raising a question mark on paleogeographic reconstructions of India and Madagascar. The continuity of the Western Dharwar Craton north of the South Maharashtra Shear Zone below the Deccan Traps—or its lack thereof—is critical for validating tectonic models correlating Madagascar with India. In this study, zircons in tonalitic basement xenoliths hosted in Deccan Trap dykes were dated in situ, using the U-Pb isotope system. The data furnish U-Pb ages that define three populations at 2527 ± 6, 2456 ± 6, and 2379 ± 9 Ma. The 2527 ± 6 Ma ages correspond to the igneous crystallization of the tonalites, whereas the 2456 ± 6 and 2379 ± 9 Ma ages date metamorphic overprints. The results help to establish for the first time that the basement is a part of the Neoarchean granitoid suite of the Western Dharwar Craton, which extends northward up to at least Talvade in central and Kihim beach in the western Deccan. By implication, the South Maharashtra Shear Zone cannot be the northern limit of the Western Dharwar Craton. The granitoids are correlated with the Neoarchean felsic intrusions (2.57–2.49) of the Masaola suite in the Antongil Block of Madagascar, supporting the existence of a Neoarchean Greater Dharwar Craton comprising the Western Dharwar Craton and the Antongil-Masora Block.

Towards a spatial understanding of trade-offs in sustainable development: A meso-scale analysis of the nexus between land use, poverty, and environment in the Lao PDR

In land systems, equitably managing trade-offs between planetary boundaries and human development needs represents a grand challenge in sustainability oriented initiatives. Informing such initiatives requires knowledge about the nexus between land use, poverty, and environment. This paper presents results from Lao PDR, where we combined nationwide spatial data on land use types and the environmental state of landscapes with village-level poverty indicators. Our analysis reveals two general but contrasting trends. First, landscapes with paddy or permanent agriculture allow a greater number of people to live in less poverty but come at the price of a decrease in natural vegetation cover. Second, people practising extensive swidden agriculture and living in intact environments are often better off than people in degraded paddy or permanent agriculture. As poverty rates within different landscape types vary more than between landscape types, we cannot stipulate a land use–poverty–environment nexus. However, the distinct spatial patterns or configurations of these rates point to other important factors at play. Drawing on ethnicity as a proximate factor for endogenous development potentials and accessibility as a proximate factor for external influences, we further explore these linkages. Ethnicity is strongly related to poverty in all land use types almost independently of accessibility, implying that social distance outweighs geographic or physical distance. In turn, accessibility, almost a precondition for poverty alleviation, is mainly beneficial to ethnic majority groups and people living in paddy or permanent agriculture. These groups are able to translate improved accessibility into poverty alleviation. Our results show that the concurrence of external influences with local—highly contextual—development potentials is key to shaping outcomes of the land use–poverty–environment nexus. By addressing such leverage points, these findings help guide more effective development interventions. At the same time, they point to the need in land change science to better integrate the understanding of place-based land indicators with process-based drivers of land use change.
