High-fidelity simulation among bachelor students in simulation groups and use of different roles.

2013

Cost limitations might challenge the use of high-fidelity simulation as a teaching-learning method. This article presents the results of a Norwegian project including two simulation studies in which simulation teaching and learning were studied among students in the second year of a three-year bachelor nursing programme. The students were organised into small simulation groups with different roles; nurse, physician, family member and observer. Based on experiences in different roles, the students evaluated the simulation design characteristics and educational practices used in the simulation. In addition, three simulation outcomes were measured; knowledge (learning), Student Satisfaction an…

Next Generation Home Sharing: Disrupting Platform Organizations with Blockchain Technology and the Internet of Things?

2020

During the last decade, the sharing economy has given birth to a number of market mediators, which have grown to become the world’s most valuable companies. Centralized sharing platforms like Uber, Didi Chuxing, and Airbnb have transformed several traditional industries. However, with the rise of the blockchain technology, some voices predict that these platform companies will soon be at risk of being disrupted themselves. In this chapter, we address the question of whether blockchain technology has given birth to a new breed of sharing economy platforms that can challenge the incumbents’ business models. We identify five different stages of the application of blockchain technology in emerg…

Chloroquine for COVID-19: rationale, facts, hopes

2020

The tragedy of the pandemic coronavirus disease 2019 (COVID-19) led to a desperate search for effective treatments. Chloroquine (CQ), an aminoquinoline used for many years for the prophylaxis and therapy of malaria and autoimmune diseases, has been put forward as a treatment option. The fact that CQ is not patented and has been in clinical use for years is a major advantage. CQ has been shown to have antiviral effects in SARS, MERS, Ebola, and HIV infections, but without data showing clinical effectiveness [1, 2]. Does the current level of evidence suffice for prescribing CQ for COVID-19?

Contingency plan for the intensive care services for the COVID-19 pandemic

2020

Resumen En enero de 2020 China identifico un nuevo virus de la familia de los Coronaviridae como causante de varios casos de neumonia de origen desconocido. Inicialmente confinado a la ciudad de Wuhan, se extendio posteriormente fuera de las fronteras chinas. En Espana, el primer caso se declaro el 31 de enero de 2020. El 11 de marzo, la Organizacion Mundial de la Salud declaro el brote de coronavirus como pandemia. El 16 de marzo habia 139 paises afectados. Ante esta situacion, las Sociedades Cientificas SEMICYUC y SEEIUC han decidido la elaboracion de este plan de contingencia para dar respuesta a las necesidades que conllevara esta nueva enfermedad. Se pretende estimar la magnitud del pr…

Suitability of the ASA Model in Nigeria

2010

This paper looks at the lending methodology adopted by ASA International in Nigeria and how the model is suited for operations within the Nigerian microfinance sector. It begins by examining the critical success factors that contribute towards ASA having a lean operations, how it manages operations efficiencies, and finally makes a set of recommendations that Nigerian Microfinance Institutions could adopt.

Impact of a stay in the intensive care unit on the preparation of Advance Directives: Descriptive, exploratory, qualitative study.

2017

Abstract Background Our objective was to assess, through a qualitative, exploratory study, the thought processes of patients regarding the formulation of advance directives (AD) after a stay in the ICU. Methods The study was conducted from May to July 2016 using telephone interviews performed by four senior ICU physicians. Inclusion criteria were: patients discharged from ICU to home > 3 months earlier. Semi-directive interviews with patients focused on 5 main points surrounding AD. Results In total, among 159 eligible patients, data from 94 (59%) were available for analysis. Among all those interviewed, 83.5% had never heard of “advance directives”. Only 2% had executed AD before ICU admis…

Monte Carlo study of surface critical behavior in the XY model.

1989

We have used Monte Carlo simulations to study the behavior of $L\ifmmode\times\else\texttimes\fi{}L\ifmmode\times\else\texttimes\fi{}D$ slabs containing classical spins which interact via nearest-neighbor $\mathrm{XY}$ coupling. The coupling constant ${J}_{S}$ for spins in the surface layer is fixed at $0.5J$. Finite-size scaling is used to analyze data for $D=59$ and to extract estimates for the surface critical exponents. We find that ${\ensuremath{\beta}}_{1}$ is in good agreement with theoretical predictions.

A finite size scaling study of the five-dimensional Ising model

1994

For systems above the marginal dimension d*, where mean field theory starts to become valid, such as Ising models in d = 5 for which d* = 4, hyperscaling is invalid and hence it was suggested that finite size scaling is not ruled by the correlation length ξ (∝ |t| −1/2 in Landau theory, t being the distance from the critical point) but by a “thermodynamic length” l (∝ |t| −2/d). Early simulation work by Binder et al. using nearest neighbor hypercubic L5 lattices with L ⩽ 7 yielded some evidence for this prediction, but the renormalized coupling constant gL = −3 + 〈M4〉/〈M2〉2 at Tc was gL ≈ −1.0 instead of the prediction of Brezin and Zinn-Justin, gL(Tc) = −3 + Γ4(1/4)/(8 π2) ≈ −0.812. In the…

Spurious finite-size instabilities in nuclear energy density functionals

2013

It is known that some well-established parametrizations of the EDF do not always provide converged results for nuclei and a qualitative link between this finding and the appearance of finite-size instabilities of SNM near saturation density when computed within the RPA has been pointed out. We seek for a quantitative and systematic connection between the impossibility to converge self-consistent calculations of nuclei and the occurrence of finite-size instabilities in SNM for the example of scalar-isovector (S=0, T=1) instabilities of the standard Skyrme EDF. We aim to establish a stability criterion based on computationally-friendly RPA calculations of SNM that is independent on the functi…
