Ebola virus disease epidemic in West Africa: Lessons learned and issues arising from West African countries

© Royal College of Physicians 2015. All rights reserved.The current Ebola virus disease (EVD) outbreak ravaging three nations in West Africa has affected more than 14,000 persons and killed over 5,000. It is the longest and most widely spread Ebola epidemic ever seen. At the time of this overview (written November 2014), having affected eight different nations, Nigeria and Senegal were able to control and eliminate the virus within a record time. Ghana has successfully, to date, kept the virus away from the country, despite economic and social relationships with affected nations. What lessons can we learn from Nigeria, Senegal and Ghana in the current epidemic? How can the world improve the health systems in low- and middle-income countries to effectively manage future outbreaks? Recently, the Royal College of Physicians launched a new partnership with the West African College of Physicians to curtail the effects of HIV/AIDS, malaria and tuberculosis in the region. We believe that strengthened health systems, skilled human resources for health and national ownership of problems are key to effective management of outbreaks such as EVD

Kaluza-Klein Holography

We construct a holographic map between asymptotically AdS_5 x S^5 solutions of 10d supergravity and vacuum expectation values of gauge invariant operators of the dual QFT. The ingredients that enter in the construction are (i) gauge invariant variables so that the KK reduction is independent of any choice of gauge fixing; (ii) the non-linear KK reduction map from 10 to 5 dimensions (constructed perturbatively in the number of fields); (iii) application of holographic renormalization. A non-trivial role in the last step is played by extremal couplings. This map allows one to reliably compute vevs of operators dual to any KK fields. As an application we consider a Coulomb branch solution and compute the first two non-trivial vevs, involving operators of dimension 2 and 4, and reproduce the field theory result, in agreement with non-renormalization theorems. This constitutes the first quantitative test of the gravity/gauge theory duality away from the conformal point involving a vev of an operator dual to a KK field (which is not one of the gauged supergravity fields).Comment: 47 pages, v2: minor improvements, version to appear in JHE

Gender balance in committees and how it impacts participation : evidence from Costa Rica's legislative assembly

Artículo originalWe examine participation by women and men in legislatures in a critical case. Previous studies found that women often participate less than men in committee hearings and plenary debates. Yet these studies were conducted in cases where women held a fairly small share of seats and generally did not hold leadership positions or have seniority – factors expected to decrease participation. We use data from the Costa Rican Legislative Assembly (2010-2012) to assess whether women still participate less than men when placed in conditions of (near) institutional equality. Costa Rica has a successful 40% gender quota, a woman president, and no immediate reelection to the Assembly so all deputies lack seniority, thus many sex barriers have been broken in Costa Rican politics. In this apparently favorable environment, do women deputies participate equally with men? We answer this question using data from two standing committees, which offer variance on the percentage of women in attendance at each session. Empirical findings suggest that women participate as much as men in committee, even when the number of women on the committee is few. We also find that committee leaders are very active participants, which underscores the importance for women of obtaining committee leadership positions

Key performance indicators for successful simulation projects

There are many factors that may contribute to the successful delivery of a simulation project. To provide a structured approach to assessing the impact various factors have on project success, we propose a top-down framework whereby 15 Key Performance Indicators (KPI) are developed that represent the level of successfulness of simulation projects from various perspectives. They are linked to a set of Critical Success Factors (CSF) as reported in the simulation literature. A single measure called Project’s Success Measure (PSM), which represents the project’s total success level, is proposed. The framework is tested against 9 simulation exemplar cases in healthcare and this provides support for its reliability. The results suggest that responsiveness to the customer’s needs and expectations, when compared with other factors, holds the strongest association with the overall success of simulation projects. The findings highlight some patterns about the significance of individual CSFs, and how the KPIs are used to identify problem areas in simulation projects.This study was supported by the Multidisciplinar Assessment of Technology Centre for Healthcare (MATCH) program (EPSRC Grant EP/F063822/1)

A Bestiary of Higher Dimensional Taub-NUT-AdS Spacetimes

We present a menagerie of solutions to the vacuum Einstein equations in six, eight and ten dimensions. These solutions describe spacetimes which are either locally asymptotically adS or locally asymptotically flat, and which have non-trivial topology. We discuss the global structure of these solutions, and their relevance within the context of M-theory.Comment: 11 pages, LaTex(v4: Comments and references added
