‘Neither invisible nor abnormal!’ Exploring the invisibility and pathologisation of LGBT people in the Greek National Health System

This article presents findings from a research study aiming at exploring in-depth experiences of lesbian, gay, bisexual and transgender (LGBT) individuals and communities in the Greek healthcare system. This was the first study of its kind in Greece. Data collected from interviews with LGBT groups and individuals, as well as doctors, suggest that homophobia and transphobia are profound factors of systematic exclusion and restriction from access to good quality healthcare. Our findings suggest that within the healthcare context, LGBT people are routinely invisibilised and/or pathologised. The authors emphasise the urgent need for challenging chronic and institutionalised invisibility experienced by LGBT people as a necessary precondition of social equality and genuine universalism within the Greek Health System

Memetic electromagnetism algorithm for surface reconstruction with rational bivariate Bernstein basis functions

Surface reconstruction is a very important issue with outstanding applications in fields such as medical imaging (computer tomography, magnetic resonance), biomedical engineering (customized prosthesis and medical implants), computer-aided design and manufacturing (reverse engineering for the automotive, aerospace and shipbuilding industries), rapid prototyping (scale models of physical parts from CAD data), computer animation and film industry (motion capture, character modeling), archaeology (digital representation and storage of archaeological sites and assets), virtual/augmented reality, and many others. In this paper we address the surface reconstruction problem by using rational Bézier surfaces. This problem is by far more complex than the case for curves we solved in a previous paper. In addition, we deal with data points subjected to measurement noise and irregular sampling, replicating the usual conditions of real-world applications. Our method is based on a memetic approach combining a powerful metaheuristic method for global optimization (the electromagnetism algorithm) with a local search method. This method is applied to a benchmark of five illustrative examples exhibiting challenging features. Our experimental results show that the method performs very well, and it can recover the underlying shape of surfaces with very good accuracy.This research is kindly supported by the Computer Science National Program of the Spanish Ministry of Economy and Competitiveness, Project #TIN2012-30768, Toho University, and the University of Cantabria.

Reduced costs with bisoprolol treatment for heart failure - An economic analysis of the second Cardiac Insufficiency Bisoprolol Study (CIBIS-II)

Background Beta-blockers, used as an adjunctive to diuretics, digoxin and angiotensin converting enzyme inhibitors, improve survival in chronic heart failure. We report a prospectively planned economic analysis of the cost of adjunctive beta-blocker therapy in the second Cardiac Insufficiency BIsoprolol Study (CIBIS II). Methods Resource utilization data (drug therapy, number of hospital admissions, length of hospital stay, ward type) were collected prospectively in all patients in CIBIS . These data were used to determine the additional direct costs incurred, and savings made, with bisoprolol therapy. As well as the cost of the drug, additional costs related to bisoprolol therapy were added to cover the supervision of treatment initiation and titration (four outpatient clinic/office visits). Per them (hospital bed day) costings were carried out for France, Germany and the U.K. Diagnosis related group costings were performed for France and the U.K. Our analyses took the perspective of a third party payer in France and Germany and the National Health Service in the U.K. Results Overall, fewer patients were hospitalized in the bisoprolol group, there were fewer hospital admissions perpatient hospitalized, fewer hospital admissions overall, fewer days spent in hospital and fewer days spent in the most expensive type of ward. As a consequence the cost of care in the bisoprolol group was 5-10% less in all three countries, in the per them analysis, even taking into account the cost of bisoprolol and the extra initiation/up-titration visits. The cost per patient treated in the placebo and bisoprolol groups was FF35 009 vs FF31 762 in France, DM11 563 vs DM10 784 in Germany and pound 4987 vs pound 4722 in the U.K. The diagnosis related group analysis gave similar results. Interpretation Not only did bisoprolol increase survival and reduce hospital admissions in CIBIS II, it also cut the cost of care in so doing. This `win-win' situation of positive health benefits associated with cost savings is Favourable from the point of view of both the patient and health care systems. These findings add further support for the use of beta-blockers in chronic heart failure

Foundations of Spline Theory: B-Splines, Spline Approximation, and Hierarchical Refinement

This chapter presents an overview of polynomial spline theory, with special emphasis on the B-spline representation, spline approximation properties, and hierarchical spline refinement. We start with the definition of B-splines by means of a recurrence relation, and derive several of their most important properties. In particular, we analyze the piecewise polynomial space they span. Then, we present the construction of a suitable spline quasi-interpolant based on local integrals, in order to show how well any function and its derivatives can be approximated in a given spline space. Finally, we provide a unified treatment of recent results on hierarchical splines. We especially focus on the so-called truncated hierarchical B-splines and their main properties. Our presentation is mainly confined to the univariate spline setting, but we also briefly address the multivariate setting via the tensor-product construction and the multivariate extension of the hierarchical approach

The social impacts of products: a review

Many agree that every product has economic, environmental, and social impacts on those who use and produce them. While environmental and economic impacts are well known and measures have been developed, our understanding of social impacts is still developing. While efforts have been made to identify social impacts, academics, and practitioners still disagree on which phenomena should be included, and few have focused on the impacts of products specifically compared with programs, policies, or other projects. The primary contribution of this review essay is to integrate scholarship from a wide array of social science and engineering disciplines that categorizes the social phenomena that are affected by products. Specifically, we identify social impacts and processes including population change, family, gender, education, stratification, employment, health and well-being, human rights, networks and communication, conflict and crime, and cultural identity/heritage. These categories are important because they can be used to inform academics and practitioners alike who are interested in creating products that generate positive social benefits for users

Incorporating participatory action research and social media as a research tool whilst Gen-Y studies abroad

Gen-Y students undertaking study abroad are electronically literate “digital natives.” However, their modes of social communication may be inadequate to support indelible learning. Many international exchange programmes have not kept pace with digital opportunities to reinforce intercultural learning whilst students are abroad. This chapter reports on qualitative findings from an Australian project that developed reflection-based curriculum for improving study abroad outcomes. In particular, we discuss participatory action research that used blogs and photo elicitation to augment reflection, intercultural skills, and professionalization. We conclude that social media and visual literacy, with carefully guided facilitation, produce a virtual “third space” where students reflect on cultural differences and strengthen their metacognitive skills for lifelong learning
