Need for closure effect on collective action intentions and behavior toward immigrants in Italy:The mediation of binding foundations and political conservatism
Why are people (de)motivated to mobilize in favor of immigrants? Addressing this question, we investigated the role of individuals' epistemic motivation (i.e., need for closure) in influencing the process of becoming motivated to participate in collective action in favor of immigrants in Italy. Specifically, the mediational role of binding moral foundations and political conservatism in explaining the relationship between need for closure and collective action in favor of immigrants was examined in three studies. It was hypothesized that a heightened need for closure would be indirectly and negatively associated with collective action in favor of immigrants, sequentially mediated first through binding moral foundations and then political conservatism. We found support for this prediction when either dispositional measure (Study 1 and Study 2) or an experimental induction (Study 3) of need for closure were used, and when both collective action intentions (Study 1 and Study 3) and behavior (Study 2) were assessed. The results suggest that need for closure constitutes a powerful motivational force that leads individuals to engage in uncertainty‐reducing evaluations and actions. We discuss these results regarding how they are related with previous work and their implications for research and practice
Making geology relevant for infrastructure and planning
The urban population is projected to rise to 66% in 2050 to 7.6 billion. This has had, and will have, a profound effect on the geological and geomorphological character of the Earth’s shallow geosphere. It is important to know the character and geometries of the geological deposits so that infrastructure is planned sensibly and sustainably, and urban areas can be reused responsibly to ensure that they help facilitate economic and social development. This brings major challenges for our cities, where there is increased pressure on resources, space and services. The geosciences have an important part to play in securing sustainable global cities - they can support urban innovation and city performance, reduce our environmental footprint and ensure greater resilience to natural hazards such as flooding and ground instability.
For more than 30 years the British Geological Survey has advanced the geoscientific understanding and 3D characterisation of urban environments, producing multi-themed spatial datasets for geohazards and ground investigation used across the environmental, planning and insurance sectors.
The BGS have collaborated with the University of Cambridge to better integrate geological data with landuse and infrastructure to look at the long-term impact on these types of activities at surface and subsurface. A 3D GeoLanduse layer was produced from the geological framework model of London. This vector-based grid means that many soil and rock properties (e.g. foundation conditions, groundwater levels, volume change potential), can be represented alongside landuse statistics and infrastructure type and correlated in the XYZ domain. Focus has been at geothermal potential of the ground surrounding residential basements and the broader correlation between geology, energy consumption and landuse at city scale using principle component analysis and cluster recognition
Provision of medical abortion by midlevel healthcare providers in Kyrgyzstan : testing an intervention to expand safe abortion services to underserved rural and periurban areas
Publisher Copyright: © 2017 World Health OrganizationObjective: To demonstrate the feasibility and safety of training midlevel healthcare providers (midwives and family nurses) to provide medical abortion and postabortion contraception in underserved areas in Kyrgyzstan. Study design: This was an implementation study at four referral facilities and 28 Felsher Obstetric Points in two districts to train their midwives and family nurses to deliver safe and effective abortion care with co-packaged mifepristone–misoprostol and provide contraceptives postabortion. The outcome of abortion — complete abortion, incomplete abortion or o-going pregnancy — was the primary end point measured. An international consultant trained 18 midwives and 14 family nurses (with midwifery diplomas) to provide medical abortion care. Supervising gynecologists based in the referral centers and study investigators based in Bishkek provided monthly monitoring of services and collection of patient management forms. A voluntary self-administered questionnaire at the follow-up visit documented women's acceptability of medical abortion services. All study data were cross-checked and entered into an online data management system for descriptive analysis. Results: Between August 2014 and September 2015, midwives provided medical abortion to 554 women with a complete abortion rate of 97.8%, of whom 62% chose to use misoprostol at home. No women were lost to follow-up. Nearly all women (99.5%) chose a contraceptive method postabortion; 61% of women receiving services completed the acceptability form, of whom more than 99% indicated a high level of satisfaction with the service and would recommend it to a friend. Conclusion: This study demonstrates that trained Kyrgyz midwives and nurses can provide medical abortion safely and effectively. This locally generated evidence can be used by the Kyrgyz Ministry of Health to reduce unintended pregnancy and expand safe abortion care to women in underserved periurban and rural settings. Implications: Success in scaling up midwife/nurse provision of medical abortion in Kyrgyzstan will require registration of mifepristone–misoprostol, regulations permanently allowing midwife/nurse provision, strengthened procurement and distribution systems to prevent stockouts of supplies, preservice training of midwives/nurses and their involvement in district level supervision, monitoring and reporting, and support from supervisors.publishersversionPeer reviewe
Evaluating quality of contraceptive counseling: An analysis of the method information index
The Method Information Index (MII) is calculated from contraceptive users\u27 responses to questions regarding counseling content-whether they were informed about methods other than the one they received, told about method-specific side effects, and advised what to do if they experienced side effects. The MII is increasingly reported in national surveys and used to track program performance, but little is known about its properties. Using additional questions, we assessed the consistency between responses and the method received in a prospective, multicountry study. We employed two definitions of consistency: (1) presence of any concordant response, and (2) absence of discordant responses. Consistency was high when asking whether users were informed about other methods and what to do about side effects. Responses were least consistent when asking whether side effects were mentioned. Adjusting for inconsistency, scores were up to 50 percent and 30 percent lower in Pakistan and Uganda, respectively, compared to unadjusted MII scores. Additional questions facilitated better understanding of counseling quality
Segregation in the twenty first century: Processes, complexities and future directions
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
Analyzing the relationship between urbanization, food supply and demand, and irrigation requirements in Jordan
The landscape surrounding urban areas is often used as farmland. With the observed expansion of urban areas over the last decades and a projected continuation of this trend, our objective was to analyze how urbanization affects food supply and demand in The Hashemite Kingdom of Jordan. We used a chain of simulation models covering components of the atmosphere (climate simulations), biosphere (crop yield calculations), and anthroposphere (simulations of urban expansion and land-use change) to calculate the effect of farmland displacement on land and water resources (hydrosphere). Our simulations show that the displacement of farmland itself has hardly any effect on cropland demand, crop yields, or irrigation water requirements. These results indicate that Jordan has sufficient productive areas available to buffer effects of urban expansion on food production for the next decades. However, this picture changes dramatically once we include changes in socioeconomy and climate in our simulations. The isolated effect of climate change results in an expected increase in irrigation water requirements of 19 MCM by 2025 and 64 MCM by 2050. It furthermore leads to an increase in cropland area of 147 km2 by 2025 and 265 km2 by 2050. While the combined analysis of urban expansion, climate change, and socioeconomic change makes optimistic assumptions on the increase in crop yields by 2050, the results still indicate a pronounced effect on cropland demands (2700 km2) and a steep increase in irrigation water requirements (439 MCM). Our simulation results highlight the importance of high resolution, spatially explicit projections of future land changes as well as the importance of spatiotemporal scenario studies at the regional level to help improving water planning strategies.The research presented in this manuscript was funded by the German Federal Ministry of Education and Research [contract 01LW0502].

A hybrid super hydrophilic ceramic membrane and carbon nanotube adsorption process for clean water production and heavy metal removal and recovery in remote locations
A novel hybrid membrane-adsorption process has been developed for the production of clean water supplies. A 0.2 μm ceramic membrane has been functionalised to produce a super-hydrophilic surface on the microfiltration membrane capable of maintaining flux with little or no fouling under normal operating conditions. The adsorbent used is a supported epoxidised carbon nanotube material capable of removing heavy metals from solution. Both the membrane and the adsorbent can be easily cleaned when necessary using only a solution of readily available vinegar. The intended aim for this new water production system is for the production of clean water in remote locations, in disaster relief zones and for humanitarian purposes. Laboratory studies have shown that the membrane is capable of maintaining flux over a significant period of time and even when tested with an extreme foulant (used motor oil) performed admirably. The rejection properties of the membrane are as expected for small pore microfiltration, i.e. microbial contamination is easily removed. The adsorbent was shown to remove heavy metals (Cd, Hg, Ni, Co and Pb) to a very high degree (>99.3% in all cases) and was easily regenerated to almost complete adsorptive capacity. The hybrid-process was briefly deployed to the Rio Las Vacas (Guatemala) as part of a basic feasibility study and the unit performed as expected. No microbial contamination was detected in the permeate and the flux was maintained consistently at one third of the clean water flux. This demonstrates the system is capable of microbial removal and has good antifouling properties
Estimate of vertical transmission of Hepatitis C virus in Pakistan in 2007 and 2012 birth cohorts.
Despite a combination of high Hepatitis C virus (HCV) prevalence, a large adult population and high fertility, no published estimates of the scale and contribution of vertical transmission to HCV incidence in Pakistan exist. The objective of this study was to estimate the number of new HCV infections occurring in Pakistan as a result of vertical transmission. We adapted a published mathematical model based on HCV antibody and viraemia prevalence, fertility rates, risk of HCV vertical transmission and children mortality rates to estimate the number of infections in the 2007 and 2012 birth cohorts nationally and in four subnational regions. We estimated that 19 708 (95% uncertainty interval [UI]: 15 941-23 819) children were vertically infected by HCV in 2007 and 21 676 (95% UI: 17 498-26 126) in 2012. The majority of these cases (72.9% and 72.5% in 2007 and 2012, respectively) occurred in Punjab. We estimated that vertical transmission as a mode of exposure accounted for a quarter of HCV infections among children under 5 years of age (25.2% in 2007 and 24.0% in 2012). CONCLUSION: Our results showed that one in 260 children born in Pakistan in 2007 and 2012 acquired HCV vertically. While currently no interventions during pregnancy and childbirth are recommended to reduce this risk, prevention, testing and treatment strategies should be considered to reduce the burden of vertical HCV infections among young children. Other routes of transmission appear to contribute the majority of HCV infections among children and must also be clarified and urgently addressed

Within-Neighborhood Patterns and Sources of Particle Pollution: Mobile Monitoring and Geographic Information System Analysis in Four Communities in Accra, Ghana
BACKGROUND: Sources of air pollution in developing country cities include transportation and industrial pollution, biomass and coal fuel use, and resuspended dust from unpaved roads.
OBJECTIVES: Our goal was to understand within-neighborhood spatial variability of particulate matter (PM) in communities of varying socioeconomic status (SES) in Accra, Ghana, and to quantify the effects of nearby sources on local PM concentration.
METHODS: We conducted 1 week of morning and afternoon mobile and stationary air pollution measurements in four study neighborhoods. PM with aerodynamic diameters
RESULTS: In our measurement campaign, the geometric means of PM2.5 and PM10 along the mobile monitoring path were 21 and 49 microg/m3, respectively, in the neighborhood with highest SES and 39 and 96 microg/m3, respectively, in the neighborhood with lowest SES and highest population density. PM2.5 and PM10 were as high as 200 and 400 microg/m3, respectively, in some segments of the path. After adjusting for other factors, the factors that had the largest effects on local PM pollution were nearby wood and charcoal stoves, congested and heavy traffic, loose dirt road surface, and trash burning.
CONCLUSIONS: Biomass fuels, transportation, and unpaved roads may be important determinants of local PM variation in Accra neighborhoods. If confirmed by additional or supporting data, the results demonstrate the need for effective and equitable interventions and policies that reduce the impacts of traffic and biomass pollution
