Improving basic life support training for medical students

Mariam Lami, Pooja Nair, Karishma GadhviFaculty of Medicine, Imperial College, London, London, UKAbstract: Questions have been raised about basic life support (BLS) training in medical education. This article addresses the research evidence behind why BLS training is inadequate and suggests recommendations for improving BLS training for medical students.Keywords: medical education, basic life suppor

Assessing social sustainability for achieving sustainable architecture

Sustainability is an inherent urban and architectural problem. It is simultaneously characterized by many different dimensions, pursuing heterogeneous and often conflicting objectives. To help address these complexities in a structured way, this paper illustrates an integrated assessment framework to tackle social sustainability, in order to support the decision-making process towards sustainable architecture. This integrated decision support framework was applied to a case study concerning a new cultural centre at the Politecnico di Torino in Italy. The aim of this paper is to propose a decision support methodological framework for the analysis, graphical visualization and evaluation of social sustainability of architectural projects. It combines three methods first, Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis, to get a guided understanding of the project and detect the best design strategies; second, the Stakeholder Analysis (SA), to develop a strategic view of the actors involved; third, the Social Return of the Investment (SROI) as a methodological tool for social impact assessment. This framework, presented through the discussion of some project solutions, helps us analyse the architectural material effect of social sustainability and answer the question: Are we investing properly and creating spaces sufficiently functional to build better conditions for our community and our city

A multi-methodological combination of the Strategic Choice Approach and the Analytic Network Process: from facts to values and vice versa

The paper proposes a new multi-methodological framework combining a Problem Structuring Method and a Multi-Criteria Decision Analysis to address the problem of composing facts and values in the decision-making process of policy making. We position our work theoretically in relation to Latour’s concept of the "collective" as a potential description of the decision-making process, with its conflicts and negotiations, openings and closures. With Latour, we can say that there are no "separate chambers" in which facts (i.e., the use of public resources, different time horizons) and values (i.e., the values of different stakeholders, the legitimacy of public decisions) are discussed; rather, all these aspects are considered together in a cycle that encompasses them, progressively expanding and contracting to arrive at a tangible result: a decision. In the paper we illustrate the transposition of the concept of this cycle in our multi-methodology, the proposal of the combination of the Strategic Choice Approach (SCA) and the Analytic Network Process (ANP)—which is absent in the literature—and we then empirically test this theoretical contribution with a case study, the repurposing of a former hospital in Ital

Exact solution for the quantum and private capacities of bosonic dephasing channels

The capacities of noisy quantum channels capture the ultimate rates of information transmission across quantum communication lines, and the quantum capacity plays a key role in determining the overhead of fault-tolerant quantum computation platforms. In the case of bosonic systems, central to many applications, no closed formulas for these capacities were known for bosonic dephasing channels, a key class of non-Gaussian channels modelling, e.g., noise affecting superconducting circuits or fiber-optic communication channels. Here we provide the first exact calculation of the quantum, private, two-way assisted quantum, and secret-key agreement capacities of all bosonic dephasing channels. We prove that that they are equal to the relative entropy of the distribution underlying the channel to the uniform distribution. Our result solves a problem that has been open for over a decade, having been posed originally by [Jiang & Chen, Quantum and Nonlinear Optics 244, 2010].Comment: 10+20 pages, 6 figures. v2 is close to the published versio

The CDF MiniPlug Calorimeters at the Tevatron

Two MiniPlug calorimeters, designed to measure the energy and lateral position of particles in the pseudorapidity region of 3.6<|eta|<5.1 of the CDF detector, have been installed as part of the Run II CDF upgrade at the Tevatron collider. Detector performance and first results from $\bar pp$ collision data are presented.Comment: Presented at `Frontier Detectors for Frontier Physics; 9th Pisa Meeting on Advanced Detectors', Biodola, Italy, 25-31 May 2003. 2 page

Approximate Reversal of Quantum Gaussian Dynamics

Recently, there has been focus on determining the conditions under which the data processing inequality for quantum relative entropy is satisfied with approximate equality. The solution of the exact equality case is due to Petz, who showed that the quantum relative entropy between two quantum states stays the same after the action of a quantum channel if and only if there is a reversal channel that recovers the original states after the channel acts. Furthermore, this reversal channel can be constructed explicitly and is now called the Petz recovery map. Recent developments have shown that a variation of the Petz recovery map works well for recovery in the case of approximate equality of the data processing inequality. Our main contribution here is a proof that bosonic Gaussian states and channels possess a particular closure property, namely, that the Petz recovery map associated to a bosonic Gaussian state sigma and a bosonic Gaussian channel N is itself a bosonic Gaussian channel. We furthermore give an explicit construction of the Petz recovery map in this case, in terms of the mean vector and covariance matrix of the state sigma and the Gaussian specification of the channel N
