Overcoming systematic global barriers to AT: a new methodology and quickstart testing through a £20m programme

Between March and June 2018, the Global Disability Innovation Hub (GDI) led a consortium tasked by the UK Department for International Development (DfID) with comprehensively scoping the barriers to Assistive Technology (AT) access in order to inform the design of a significant new global programme. This paper summarises the evidence examined in that Scoping Report; presents the methodology it proposed; and shares the early findings for the subsequent £20m funded programme, called ‘AT2030 – Access to Assistive Technology for All’ (www.AT2030.org).The Scoping Report sought to unpick the multi-layered and multi-faceted ways in which economic, social, and political factors interact to create barriers to AT for those who need it the most. The team used a mixed-methods approach which was necessarily flexible and iterative, bringing in expertise from the broad partnership. The data showed that the challenge of AT access represents a complex web of market and system failures, compounded by a lack of participation from AT users, that results in a supply/demand mismatch affecting almost a billion people. This makes AT access one of the most pressing global challenges. Because of poor data on use, need and impact this ‘wicked problem’ is largely hidden from view to all but those facing the daily struggles its absence creates. Yet at an individual, family and community level there is no doubt at all about the implications of lack of access to appropriate AT; isolation, economic and social exclusion, poor physical and mental health, and reduced life expectancy. Our evidence suggests that barriers to AT access are about far more than just cost. Issues such as undeveloped policy frameworks, inefficient or non-existent markets, poorly resourced services, stigma and discrimination all play a role, often with a gender impact. The Scoping Report proposed that the resulting global programme (AT2030) trial strategic interventions based on the principles of: building a global mission-led approach; generating better research and data; piloting market-shaping activity; delivering systems strengthening interventions; harnessing innovation; and building community participating and capacity. Findings from the first ten months of delivery have reinforced and confirmed the need for a mission-led approach to AT, embedded within a normative framework of social development. ‘Amazing early results’1 have resulted in a slightly tightened impact framework (theory of change) along with doubled investment. The programme is still in its early stages, but the working assumption is still that the participation of AT users is a necessary factor in the design of innovative solutions, and moreover that the availability of AT products alone is not sufficient to ‘enable a lifetime of potential’ without a systematic approach to inclusion

Vacuum Photon Splitting in Lorentz-Violating Quantum Electrodynamics

Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.Comment: 4 pages, minor wording changes, references added, accepted in Physical Review Letter

Critical Junctures in Assistive Technology and Disability Inclusion

It is clear from the events of the last 18 months that while technology has a huge potential for transforming the way we live and work, the entire ecosystem—from manufacturing to the supply chain—is vulnerable to the vagaries of that ecosystem, as well as having the potential to exacerbate new and existing inequalities [...

Trust and Risk Relationship Analysis on a Workflow Basis: A Use Case

Trust and risk are often seen in proportion to each other; as such, high trust may induce low risk and vice versa. However, recent research argues that trust and risk relationship is implicit rather than proportional. Considering that trust and risk are implicit, this paper proposes for the first time a novel approach to view trust and risk on a basis of a W3C PROV provenance data model applied in a healthcare domain. We argue that high trust in healthcare domain can be placed in data despite of its high risk, and low trust data can have low risk depending on data quality attributes and its provenance. This is demonstrated by our trust and risk models applied to the BII case study data. The proposed theoretical approach first calculates risk values at each workflow step considering PROV concepts and second, aggregates the final risk score for the whole provenance chain. Different from risk model, trust of a workflow is derived by applying DS/AHP method. The results prove our assumption that trust and risk relationship is implicit

On the Strength of Spin-Isospin Transitions in A=28 Nuclei

The relations between the strengths of spin-isospin transition operators extracted from direct nuclear reactions, magnetic scattering of electrons and processes of semi-leptonic weak interactions are discussed.Comment: LaTeX, 8 pages, 1Postscript with figur

The response of a neutral atom to a strong laser field probed by transient absorption near the ionisation threshold

We present transient absorption spectra of an extreme ultraviolet attosecond pulse train in helium dressed by an 800 nm laser field with intensity ranging from $2times10^{12}$ W/cm$^2$ to $2times10^{14}$ W/cm$^2$. The energy range probed spans 16-42 eV, straddling the first ionisation energy of helium (24.59 eV). By changing the relative polarisation of the dressing field with respect to the attosecond pulse train polarisation we observe a large change in the modulation of the absorption reflecting the vectorial response to the dressing field. With parallel polarized dressing and probing fields, we observe significant modulations with periods of one half and one quarter of the dressing field period. With perpendicularly polarized dressing and probing fields, the modulations of the harmonics above the ionisation threshold are significantly suppressed. A full-dimensionality solution of the single-atom time-dependent Schr odinger equation obtained using the recently developed ab-initio time-dependent B-spline ADC method reproduce some of our observations

"Give Us the Chance to Be Part of You, We Want Our Voices to Be Heard": Assistive Technology as a Mediator of Participation in (Formal and Informal) Citizenship Activities for Persons with Disabilities Who Are Slum Dwellers in Freetown, Sierra Leone.

The importance of assistive technology (AT) is gaining recognition, with the World Health Organisation (WHO) set to publish a Global Report in 2022. Yet little is understood about access for the poorest, or the potential of AT to enable this group to participate in the activities of citizenship; both formal and informal. The aim of this qualitative study was to explore AT as mediator of participation in citizenship for persons with disabilities who live in two informal settlements in Freetown, Sierra Leone (SL). The paper presents evidence from 16 participant and 5 stakeholder interviews; 5 focus groups and 4 events; combining this with the findings of a house-to-house AT survey; and two national studies-a country capacity assessment and an informal markets deep-dive. Despite citizenship activities being valued, a lack of AT was consistently reported and hindered participation. Stigma was also found to be a major barrier. AT access for the poorest must be addressed if citizenship participation for persons with disabilities is a genuine global intention and disability justice is to become a reality

Inclusion and Independence: The impact of Mobile Technology on the Lives of Persons with Disabilities in Kenya and Bangladesh

Globally, mobile technology plays a significant role connecting and supporting people with disabilities. However, there has been limited research focused on understanding the impact of mobile technology in the lives of persons with disabilities in low or middle- income countries. This paper presents the findings of a participatory photovoice study looking at the role that mobile phones play in the daily lives of 16 persons with disabilities in Kenya and Bangladesh. Participants used a combination of pictures and voice recordings to capture their own stories and illustrate the impact that mobile phone use has on their lives. Through thematic analysis, we categorized the benefits of mobile phones captured by participants as 1) Improved social connection; 2) Increased independence and 3) Access to opportunities. While mobile phones are ubiquitously used for communication, for persons with disabilities they become essential assistive technologies that bridge barriers to opportunities which are not accessible otherwise. Our paper adds evidence to the need for mobile phones for persons with disabilities to enable communication and connectivity in support of development

Do Hadronic Charge Exchange Reactions Measure Electroweak L = 1 Strength?

An eikonal model has been used to assess the relationship between calculated strengths for first forbidden beta decay and calculated cross sections for (p,n) charge exchange reactions. It is found that these are proportional for strong transitions, suggesting that hadronic charge exchange reactions may be useful in determining the spin-dipole matrix elements for astrophysically interesting leptonic transitions.Comment: 14 pages, 5 figures, Submitted to Physical Review
