    The aim of this study is the comparison of 2 studies looking at the barriers to access of diabetes care and medicines in the Philippines and Vietnam. These studies used the Rapid Assessment Protocol for Insulin Access. Diabetes care is provided in specialized facilities and appropriate referral systems are lacking. In Vietnam, no problems were reported with regard to diagnostic tools, whereas this was a concern in the public sector in the Philippines. Both countries had high prices for medicines in comparison to international standards. Availability of medicines was better in Vietnam than in the Philippines, especially with regard to insulin. This affected adherence as did a lack of patient education. As countries aim to provide health care to the majority of their populations through universal coverage, the challenge of diabetes cannot be neglected. Trying to achieve universal coverage in parallel to decentralization, national and local governments need adapted guidance for this

    BACKGROUND: In order to improve the health of people with Type 1 diabetes in developing countries, a clear analysis of the constraints to insulin access and diabetes care is needed. We developed a Rapid Assessment Protocol for Insulin Access, comprising a series of questionnaires as well as a protocol for the gathering of other data through site visits, discussions, and document reviews. METHODS: The Rapid Assessment Protocol for Insulin Access draws on the principles of Rapid Assessment Protocols which have been developed and implemented in several different areas. This protocol was adapted through a thorough literature review on diabetes, chronic condition management and medicine supply in developing countries. A visit to three countries in sub-Saharan Africa and meetings with different experts in the field of diabetes helped refine the questionnaires. Following the development of the questionnaires these were tested with various people familiar with diabetes and/or healthcare in developing countries. The Protocol was piloted in Mozambique then refined and had two further iterations in Zambia and Mali. Translations of questionnaires were made into local languages when necessary, with back translation to ensure precision. RESULTS: In each country the protocol was implemented in 3 areas – the capital city, a large urban centre and a predominantly rural area and their respective surroundings. Interviews were carried out by local teams trained on how to use the tool. Data was then collected and entered into a database for analysis. CONCLUSION: The Rapid Assessment Protocol for Insulin Access was developed to provide a situational analysis of Type 1 diabetes, in order to make recommendations to the national Ministries of Health and Diabetes Associations. It provided valuable information on patients' access to insulin, syringes, monitoring and care. It was thus able to sketch a picture of the health care system with regards to its ability to care for people with diabetes. In all countries where this tool was used the involvement of local stakeholders resulted in the process acting as a catalyst in bringing diabetes to the attention of the health authorities

    Hydrograph Prediction - How much skill?

    No full text
    International audienceThe matching of estimated to observed hydrograph shape is central to much hydrological analysis. This research note quantifies built-in biases that tend to inflate goodness of fit indicies, biases that arise from the similarity of geometry between observed and estimated hydrographs

    Phase boundaries in deterministic dense coding

    Full text link
    We consider dense coding with partially entangled states on bipartite systems of dimension d×dd\times d, studying the conditions under which a given number of messages, NN, can be deterministically transmitted. It is known that the largest Schmidt coefficient, λ0\lambda_0, must obey the bound λ0d/N\lambda_0\le d/N, and considerable empirical evidence points to the conclusion that there exist states satisfying λ0=d/N\lambda_0=d/N for every dd and NN except the special cases N=d+1N=d+1 and N=d21N=d^2-1. We provide additional conditions under which this bound cannot be reached -- that is, when it must be that λ0<d/N\lambda_0<d/N -- yielding insight into the shapes of boundaries separating entangled states that allow NN messages from those that allow only N1N-1. We also show that these conclusions hold no matter what operations are used for the encoding, and in so doing, identify circumstances under which unitary encoding is strictly better than non-unitary.Comment: 7 pages, 1 figur

    Effective Dielectric Tensor for Electromagnetic Wave Propagation in Random Media

    Full text link
    We derive exact strong-contrast expansions for the effective dielectric tensor \epeff of electromagnetic waves propagating in a two-phase composite random medium with isotropic components explicitly in terms of certain integrals over the nn-point correlation functions of the medium. Our focus is the long-wavelength regime, i.e., when the wavelength is much larger than the scale of inhomogeneities in the medium. Lower-order truncations of these expansions lead to approximations for the effective dielectric constant that depend upon whether the medium is below or above the percolation threshold. In particular, we apply two- and three-point approximations for \epeff to a variety of different three-dimensional model microstructures, including dispersions of hard spheres, hard oriented spheroids and fully penetrable spheres as well as Debye random media, the random checkerboard, and power-law-correlated materials. We demonstrate the importance of employing nn-point correlation functions of order higher than two for high dielectric-phase-contrast ratio. We show that disorder in the microstructure results in an imaginary component of the effective dielectric tensor that is directly related to the {\it coarseness} of the composite, i.e., local volume-fraction fluctuations for infinitely large windows. The source of this imaginary component is the attenuation of the coherent homogenized wave due to scattering. We also remark on whether there is such attenuation in the case of a two-phase medium with a quasiperiodic structure.Comment: 40 pages, 13 figure

    An Inquiry into Hope and Imagination in Jesuit Education: Ignatian Design Thinking as a Lens for Exploration

    Get PDF
    Hope and imagination are foundational to a Jesuit education, and as central tenets, inform teaching and learning through Ignatian pedagogy. The authors explore hope and imagination in the Jesuit context through the lens of scholar-practitioner inquiry, drawing from the local context and practice of an Ignatian design thinking course as a source of knowledge. This inquiry approach is rooted in practice-based research, and situates scholarly exploration through lines of inquiry and problems of practice, specifically exploring how design thinking fosters curiosity and creates space for teaching imagination and hope. The authors draw on their teaching experiences, course design, and professional experience as educators at Loyola University Chicago, providing practical pedagogical strategies offered in the Ignatian design thinking course. As they explore how hope and imagination intersect with design thinking, they scaffold hope and imagination as essential pedagogical strategies for teaching and learning in the Jesuit tradition, providing a foundation for numerous praxis and scholarship articles that comprise this special issue. Through this inquiry, the authors propose a framework linking curiosity, imagination, and hope, which all play a distinct role in Jesuit education, leading to a call to action for further research and exploration around this topic

    Animals Serving the Handicapped

    Mankind for centuries has been hiding or ignoring the less than perfect examples of its own species. Society has recently recognized this problem by undertaking goals to mainstream into daily life those people with special needs. This is evident by the appropriation of tax monies and public funds for the building of hospitals designed with special living quarters for the handicapped, for the development of equipment and prosthetic devices intended to normalize the appearance and abilities of the handicapped, for legislation and changing of architectural regulations to provide increased accessibility for the disabled, for providing attendant care and jobs for the disabled, and for changing the general public\u27s concept of the norm in regards to those with special needs. However in times of economic difficulties, advances in technological aids, accessibility, and general acceptance of the handicapped into society have been slow. Society is recently exploring ways in which animals can be specially trained to assist the handicapped in performing the daily tasks of qn independent life style. Here we will review the overall benefits of animals in improving the well-being of the handicapped, the specialized training received by such animals, and legislative regulations pertaining to the legal rights of disabled individuals using these specially trained animals

    Long-range memory model of trading activity and volatility

    Get PDF
    Earlier we proposed the stochastic point process model, which reproduces a variety of self-affine time series exhibiting power spectral density S(f) scaling as power of the frequency f and derived a stochastic differential equation with the same long range memory properties. Here we present a stochastic differential equation as a dynamical model of the observed memory in the financial time series. The continuous stochastic process reproduces the statistical properties of the trading activity and serves as a background model for the modeling waiting time, return and volatility. Empirically observed statistical properties: exponents of the power-law probability distributions and power spectral density of the long-range memory financial variables are reproduced with the same values of few model parameters.Comment: 12 pages, 5 figure
