    How migration policies moderate the diffusion of terrorism

    Get PDF
    There is an ongoing debate among practitioners and scholars about the security consequences of transnational migration. Yet, existing work has not yet fully taken into account the policy instruments states have at their disposal to mitigate these risks, and we lack reliable evidence for the effectiveness of such measures. The following research addresses both shortcomings as we analyze whether and to what extent national migration policies affect the diffusion of terrorism via population movements. Spatial analyses report robust support for a moderating influence of states’ policies: while terrorism can travel from one country to another via larger migration populations, this only applies to target countries with extremely lax regulations and control mechanisms. This research sheds new light on the security implications of population movements, and it crucially adds to our understanding of governments’ instruments for addressing migration challenges as well as their effectiveness

    This paper evaluates the effects of thermal insulation on thermal comfort in low-income tropical housing in Uganda. Dynamic thermal simulations are conducted to assess the effects of wall, roof and floor insulation strategies. 96 combination scenarios are simulated for various geometries, insulation and construction methods. Adaptive approach is used to evaluate the conditions within the case study buildings. The results indicate that external wall insulation improves thermal comfort in all conditions whereas internal wall and floor insulation may deteriorate the conditions. Roof insulation is the most effective strategy to reduce the risk of overheating. Due to the effectiveness of roof insulation and marginal improvements of external wall insulation, especially for brick walls, wall insulation may be disregarded when used in conjunction with roof insulation

    Contemporary Discourses of Green Political Economy: A Q Method Analysis

    Get PDF
    For over two decades, the concept of sustainable development has been salient in political discourse. But its promise of reconciling economic development, social welfare, and environmental sustainability has proven rather elusive. In recent years, we've seen numerous competing concepts emerge in debates about sustainable economic development. While many advance ideas of a green economy and green growth, others talk about wellbeing, gross national happiness, inclusive wealth, harmony with nature, de-growth, steady-state economy, and buenvivir (living well). This rhetorical diversity shows that there is no single vision for reconciling environmental sustainability and economic development. But the varied terminology itself obscures actual points of agreement and disagreement. This article reports on a bilingual ‘Q study’ of international debates about sustainable economic development. It reveals that three discourses underpin these debates: Radical Transformationism; Cooperative Reformism; and Statist Progressivism. The article dissects these discourses and contextualizes their key points of contention in wider sustainability debates over the past two decades

    PrEP as a feature in the optimal landscape of combination HIV prevention in sub-Saharan Africa

    INTRODUCTION: The new WHO guidelines recommend offering pre-exposure prophylaxis (PrEP) to people who are at substantial risk of HIV infection. However, where PrEP should be prioritised, and for which population groups, remains an open question. The HIV landscape in sub-Saharan Africa features limited prevention resources, multiple options for achieving cost saving, and epidemic heterogeneity. This paper examines what role PrEP should play in optimal prevention in this complex and dynamic landscape. METHODS: We use a model that was previously developed to capture subnational HIV transmission in sub-Saharan Africa. With this model, we can consider how prevention funds could be distributed across and within countries throughout sub-Saharan Africa to enable optimal HIV prevention (that is, avert the greatest number of infections for the lowest cost). Here, we focus on PrEP to elucidate where, and to whom, it would optimally be offered in portfolios of interventions (alongside voluntary medical male circumcision, treatment as prevention, and behaviour change communication). Over a range of continental expenditure levels, we use our model to explore prevention patterns that incorporate PrEP, exclude PrEP, or implement PrEP according to a fixed incidence threshold. RESULTS: At low-to-moderate levels of total prevention expenditure, we find that the optimal intervention portfolios would include PrEP in only a few regions and primarily for female sex workers (FSW). Prioritisation of PrEP would expand with increasing total expenditure, such that the optimal prevention portfolios would offer PrEP in more subnational regions and increasingly for men who have sex with men (MSM) and the lower incidence general population. The marginal benefit of including PrEP among the available interventions increases with overall expenditure by up to 14% (relative to excluding PrEP). The minimum baseline incidence for the optimal offer of PrEP declines for all population groups as expenditure increases. We find that using a fixed incidence benchmark to guide PrEP decisions would incur considerable losses in impact (up to 7%) compared with an approach that uses PrEP more flexibly in light of prevailing budget conditions. CONCLUSIONS: Our findings suggest that, for an optimal distribution of prevention resources, choices of whether to implement PrEP in subnational regions should depend on the scope for impact of other possible interventions, local incidence in population groups, and total resources available. If prevention funding were to become restricted in the future, it may be suboptimal to use PrEP according to a fixed incidence benchmark, and other prevention modalities may be more cost-effective. In contrast, expansions in funding could permit PrEP to be used to its full potential in epidemiologically driven prevention portfolios and thereby enable a more cost-effective HIV response across Africa

    Segregation in the twenty first century: Processes, complexities and future directions

    Get PDF
    Economic inequality, international migration and urban transformation have generated fresh interest in segregation and given new social significance to questions of socio‐spatial separation and interaction. At the same time, advances in data, methods and theory are opening up new avenues of inquiry that push the focus beyond simple measures of unevenness of residential patterns towards more nuanced analysis of spatial asymmetry, structure and scale. There is also a drive towards considering spaces and activities outside the neighbourhood, bringing new richness to our understanding of how various social groups interact in the various aspects of their lives. These processes and complexities form the backdrop for our special issue and we reflect on the implications for future priorities in research on segregation in the twenty first century

    Multidisciplinary and participatory workshops with stakeholders in a community of extreme poverty in the Peruvian Amazon: Development of priority concerns and potential health, nutrition and education interventions

    <p>Abstract</p> <p>Background</p> <p>Communities of extreme poverty suffer disproportionately from a wide range of adverse outcomes, but are often neglected or underserved by organized services and research attention. In order to target the first Millennium Development Goal of eradicating extreme poverty, thereby reducing health inequalities, participatory research in these communities is needed. Therefore, the purpose of this study was to determine the priority problems and respective potential cost-effective interventions in Belen, a community of extreme poverty in the Peruvian Amazon, using a multidisciplinary and participatory focus.</p> <p>Methods</p> <p>Two multidisciplinary and participatory workshops were conducted with important stakeholders from government, non-government and community organizations, national institutes and academic institutions. In Workshop 1, participants prioritized the main health and health-related problems in the community of Belen. Problem trees were developed to show perceived causes and effects for the top six problems. In Workshop 2, following presentations describing data from recently completed field research in school and household populations of Belen, participants listed potential interventions for the priority problems, including associated barriers, enabling factors, costs and benefits.</p> <p>Results</p> <p>The top ten priority problems in Belen were identified as: 1) infant malnutrition; 2) adolescent pregnancy; 3) diarrhoea; 4) anaemia; 5) parasites; 6) lack of basic sanitation; 7) low level of education; 8) sexually transmitted diseases; 9) domestic violence; and 10) delayed school entry. Causes and effects for the top six problems, proposed interventions, and factors relating to the implementation of interventions were multidisciplinary in nature and included health, nutrition, education, social and environmental issues.</p> <p>Conclusion</p> <p>The two workshops provided valuable insight into the main health and health-related problems facing the community of Belen. The participatory focus of the workshops ensured the active involvement of important stakeholders from Belen. Based on the results of the workshops, effective and essential interventions are now being planned which will contribute to reducing health inequalities in the community.</p

    Assessment of solar shading strategies in low-income tropical housing: the case of Uganda

    Developing countries in tropical and subtropical areas will be the worst hit by climate change. Very little research has been done to assess the impact of climate change on thermal comfort in low-income housing in these regions. The effects of solar shading strategies and solar absorptance properties of walls and roofs on thermal comfort in Ugandan low-income housing are studied in this paper. Various shading strategies including curtains, roof and window overhangs, veranda and trees as well as effects of painting on solar heat gain and thermal comfort are modelled using EnergyPlus software. An adaptive approach for naturally ventilated buildings defined by the European Committee for Standardization standard BS EN 15251:2007 is used to assess the conditions. According to the results, solar shading is less effective in meeting thermal comfort requirements and it should be used in conjunction with other strategies to achieve desirable results. White painting, in contrast, significantly improved the conditions and significantly reduced the risk of overheating. Solar shading proved to be effective during the hottest periods of the year, reducing the risk of extreme overheating by up to 52%
