Disability and disaster recovery: a tale of two cities?

This paper examines the connections between disability and disaster from a global perspective. Concepts from the research and policy literature are used to distinguish between individual and social models of disability, and between natural hazards and human disasters. These concepts are then employed to investigate data on the response to disabled people’s recovery needs in two recent case studies: the Asian tsunami and Hurricane Katrina. The analysis combines primary, secondary and tertiary sources to explore disability issues in the reconstruction of inclusive communities and the lessons that may be learned about disaster preparedness in poor communities. The conclusions suggest that more attention should be paid to social model approaches, particularly in understand global links with poverty, and that disabled people’s organisations should be resourced as agents of disaster recovery and preparedness

Lifestyle Coaching for Mental Health Difficulties: Scoping Review

Purpose: UK mental health strategy calls for interventions that empower people to selfmanage their condition. In lifestyle coaching, coach and client work collaboratively on positive behaviour change to improve client health. There is debate about the appropriateness of coaching for mental health, yet claims have not been supported with evidence. Therefore, this study sought to explore the nature and scope of existing research literature in this field. Design/methodology/approach: Scoping review. Findings: The growing evidence-base shows positive outcomes of coaching; for instance symptom reduction, enhanced self-management and achievement of personal goals. Research limitations/implications: The evidence-base is small and of variable quality, offering insights that warrant further exploration. Practical implications: Coaching not only supports better self-management but also addresses further mental health strategy priorities (such as improved physical health and social functioning). Coaches need not be mental health experts; therefore coaching may be a cost-effective intervention. Social implications: As mental ill-health prevalence continues to rise despite widespread use of IAPT and medication, there is a need to explore how novel approaches such as coaching might be integrated into mental healthcare. Originality/value: This was the first study to collate the evidence on mental health coaching, highlighting its extensive potential, which should be further explored in research and practic

An Operational evaluation of head up displays for civil transport operations. NASA/FAA phase 3 report

The advantages and disadvantages of head-up displays (HUDs) in commercial jet transport approach and landing operations was evaluated. Ten airline captains currently qualified in the B-727 aircraft flew a series of instrument landing system (ILS) and nonprecision approaches in a motion base simulator using both a flight director HUD concept and a flightpath HUD concept as well as conventional head-down instruments under a variety of environmental and operational conditions to assess: (1) the potential benefits of these HUDs in airline operations; (2) problems which might be associated with their use; and (3) flight crew training requirements and flight crew operating procedures suitable for use with the HUDs. Results are presented in terms of objective simulator based performance measures, subject pilot opinion and rating data, and observer data

Cascading parallel fractures on Enceladus

Active eruptions from the south polar region of Saturn's small (~500 km diameter) moon Enceladus are concentrated along a series of lineaments known as the `tiger stripes', thought to be partially open fissures that connect to the liquid water ocean beneath the ice shell. Whereas aspects of the tiger stripes have been addressed in previous work, no study to date simultaneously explains why they should be located only at the south pole, why there are multiple approximately parallel and regularly spaced fractures, and what accounts for their spacing of ~35 km. Here we propose that secular cooling and the resulting ice shell thickening and global tensile stresses cause the first fracture to form at one of the poles, where the ice shell is thinnest due to tidal heating. The tensile stresses are thereby partially relieved, preventing a similar failure at the opposite pole. We propose that subsequent activity then concentrates in the vicinity of the first fracture as the steadily erupted water ice loads the flanks of the open fissure, causing bending in the surrounding elastic plate and further tensile failure in bands parallel to the first fracture, leading to a cascading sequence of parallel fissures until the conditions no longer permit through-going fractures.Comment: 18 pages, 9 figure

Polyparameter linear free energy relationship for wood char–water sorption coefficients of organic sorbates

The definitive version was published in Environmental Toxicology and Chemistry 34 (2015): 1464-1471, doi:10.1002/etc.2951.Black carbons (BCs), including soots, chars, activated carbons, and engineered nanocarbons, have different surface properties, but we do not know to what extent these affect their sorbent properties. To evaluate this for an environmentally ubiquitous form of BC, biomass char, we probed the surface of a well-studied wood char using 14 sorbates exhibiting diverse functional groups and then fit the data with a polyparameter linear free energy relationship (ppLFER) to assess the importance of the various possible sorbate-char surface interactions. Sorption from water to water-wet char evolved with the sorbate's degree of surface saturation and depended on only a few sorbate parameters: log Kd(L/kg) = [(4.03 ± 0.14) + (-0.15 ± 0.04) log ai)] V + [(-0.28 ± 0.04) log ai)] S + (-5.20 ± 0.21) B where ai is the aqueous saturation of the sorbate i, V is McGowan’s characteristic volume, S reflects polarity, and B represents the electron-donation basicity. As generally observed for activated carbon, the sorbate’s size encouraged sorption from water to the char, while its electron donation/proton acceptance discouraged sorption from water. However, the magnitude and saturation dependence differed significantly from what has been seen for activated carbons, presumably reflecting the unique surface chemistries of these two BC materials and suggesting BC-specific sorption coefficients will yield more accurate assessments of contaminant mobility and bioavailability and evaluation of a site's response to remediation.This material is based upon work supported by the U.S. Army Corps of Engineering, Humphreys Engineer Center Support Activity under Contract No. W912HQ-10-C-0005 awarded as part of the SERDP program.2016-05-1

SMonitoring the operational impact of insecticide usage for malaria control on Anopheles funestus from Mozambique

<p>Abstract</p> <p>Background</p> <p>Indoor residual spraying (IRS) has again become popular for malaria control in Africa. This combined with the affirmation by WHO that DDT is appropriate for use in the absence of longer lasting insecticide formulations in some malaria endemic settings, has resulted in an increase in IRS with DDT as a major malaria vector control intervention in Africa. DDT was re-introduced into Mozambique's IRS programme in 2005 and is increasingly becoming the main insecticide used for malaria vector control in Mozambique. The selection of DDT as the insecticide of choice in Mozambique is evidence-based, taking account of the susceptibility of <it>Anopheles funestus </it>to all available insecticide choices, as well as operational costs of spraying.</p> <p>Previously lambda cyhalothrin had replaced DDT in Mozambique in 1993. However, resistance appeared quickly to this insecticide and, in 2000, the pyrethroid was phased out and the carbamate bendiocarb introduced. Low level resistance was detected by biochemical assay to bendiocarb in 1999 in both <it>An. funestus </it>and <it>Anopheles arabiensis</it>, although this was not evident in WHO bioassays of the same population.</p> <p>Methods</p> <p>Sentinel sites were established and monitored for insecticide resistance using WHO bioassays. These assays were conducted on 1–3 day old F1 offspring of field collected adult caught <it>An. funestus </it>females to determine levels of insecticide resistance in the malaria vector population. WHO biochemical assays were carried out to determine the frequency of insecticide resistance genes within the same population.</p> <p>Results</p> <p>In surveys conducted between 2002 and 2006, low levels of bendiocarb resistance were detected in <it>An. funestus</it>, populations using WHO bioassays. This is probably due to significantly elevated levels of Acetylcholinesterase levels found in the same populations. Pyrethroid resistance was also detected in populations and linked to elevated levels of p450 monooxygenase activity. One site had shown reduction in pyrethroid resistance since the base line in 1999.</p

For example, an experiment may involve samples from several groups or may investigate changes in gene expression over time for several subjects, leading to large three-way data sets. In response to this increase in data complexity, we propose some extensions to the plaid model, a biclustering method developed for the analysis of gene expression data. This model-based method lends itself to the incorporation of any additional structure such as external grouping or repeated measures. We describe how the extended models may be fitted and illustrate their use on real data

Developing global maps of insecticide resistance risk to improve vector control.

Background Significant reductions in malaria transmission have been achieved over the last 15 years with elimination occurring in a small number of countries, however, increasing drug and insecticide resistance threatens these gains. Insecticide resistance has decreased the observed mortality to the most commonly used insecticide class, the pyrethroids, and the number of alternative classes approved for use in public health is limited. Disease prevention and elimination relies on operational control of Anopheles malaria vectors, which requires the deployment of effective insecticides. Resistance is a rapidly evolving phenomena and the resources and human capacity to continuously monitor vast numbers of mosquito populations in numerous locations simultaneously are not available. Methods Resistance data are obtained from published articles, by contacting authors and custodians of unpublished data sets. Where possible data is disaggregated to single sites and collection periods to give a fine spatial resolution. Results Currently the data set includes data from 1955 to October 2016 from 71 malaria endemic countries and 74 anopheline species. This includes data for all four classes of insecticides and associated resistance mechanisms. Conclusions Resistance is a rapidly evolving phenomena and the resources and human capacity to continuously monitor vast numbers of mosquito populations in numerous locations simultaneously are not available. The Malaria Atlas Project-Insecticide Resistance (MAP-IR) venture has been established to develop tools that will use available data to provide best estimates of the spatial distribution of insecticide resistance and help guide control programmes on this serious issue
