Multidisciplinary obstetric simulated emergency scenarios (MOSES): Promoting patient safety in obstetrics with teamwork‐focused interprofessional simulations

Abstract: Introduction:We describe an example of simulation-based interprofessional continuing education, the multidisciplinary obstetric simulated emergency scenarios (MOSES) course, which was designed to enhance nontechnical skills among obstetric teams and, hence, improve patient safety.

Capital and liquidity ratios and financial distress. Evidence from the European banking industry

Abstract: Using a large bank-level dataset, we test the relevance of both structural liquidity and capital ratios, as defined in Basel III, on banks' probability of failure. To include all relevant episodes of bank failure and distress (F&D) occurring in the EU-28 member states over the past decade, we develop a broad indicator that includes information not only on bankruptcies, liquidations, under receivership and dissolved banks, but also accounts for state interventions, mergers in distress and EBA stress test results. Estimates from several versions of the logistic probability model indicate that the likelihood of failure and distress decreases with increased liquidity holdings, while capital ratios are significant only for large banks. Our results provide support for Basel III's initiatives on structural liquidity and for the increased regulatory focus on large and systemically important banks.

Machine learning approach for computing optical properties of a photonic crystal fiber

Abstract: Photonic crystal fibers (PCFs) are the specialized optical waveguides that led to many interesting applications ranging from nonlinear optical signal processing to high-power fiber amplifiers. In this paper, machine learning techniques are used to compute various optical properties including effective index, effective mode area, dispersion and confinement loss for a solid-core PCF. These machine learning algorithms based on artificial neural networks are able to make accurate predictions of above-mentioned optical properties for usual parameter space of wavelength ranging from 0.5-1.8 µm, pitch from 0.8-2.0 µm, diameter by pitch from 0.6-0.9 and number of rings as 4 or 5 in a silica solid-core PCF. We demonstrate the use of simple and fast-training feed-forward artificial neural networks that predicts the output for unknown device parameters faster than conventional numerical simulation techniques. Computation runtimes required with neural networks (for training and testing) and Lumerical MODE solutions are also compared.

Nurses' knowledge of and attitudes towards sexuality and the relationship of these with nursing practice

Abstract: Issues concerning sex and sexuality are relevant to nursing practice. The objective of this study was to determine the relationship between knowledge of and attitude towards sexuality, and nursing practice. Nursing practice in this case was defined as the discussion of sexuality with the patient, with particular reference to taking a sexual history on admission to the ward. A multi-choice questionnaire with sections establishing demographic details and nursing practice, and including the Sex, Knowledge and Attitude Test (SKAT), was administered to 357 registered general nurses (RGNs). Results show a relationship between knowledge and attitude but no relationship between either of these and the nursing practice scale. However, a slight but significant correlation between receiving teaching about sexual history taking and questioning patients about sexuality on admission suggests that nursing practice and knowledge are weakly related. There is evidence that factors other than those within the scope of this study influence all three independent variables, and these are discussed. The implications of the study suggest the need for an improvement in nurse education regarding sexuality at all stages of training.
