In hospitals and health systems, ensuring that standards for the quality of patient care are established and continuous improvement processes are in place are among the board's most fundamental responsibilities. A recent survey has examined governance oversight of patient care quality at 123 nonprofit community health systems and compared their practices with current benchmarks of good governance. The findings show that 88% of the boards have established standing committees on patient quality and safety, nearly all chief executive officers' performance expectations now include targets related to patient quality and safety, and 96% of the boards regularly receive formal written reports regarding their organizations' performance in relation to quality measures and standards. However, there continue to be gaps between present reality and current benchmarks of good governance in several areas. These gaps are somewhat greater for independent systems than for those affiliated with a larger parent organization. © 2010 by the American College of Medical Quality.

A full-field thermoelastic stress analysis infrared (TSA-IR) method is used to investigate the possibility of inspecting for out of plane fiber waviness in composite structures. Two different waviness profiles are generated and compared to control specimen having no anomalies. Tension and compression loading schemes are investigated and the TSA-IR emissions are compared to cross-sectional investigations. A subset of the specimens is also notched to investigate the thermal emissions from holes when compared to the waviness. The interaction of the hole and waviness shows the errors that can be introduced when using TSA-IR for quantitative analysis. © 2014 Copyright Taylor & Francis Group, LLC.

The traditional Extended Kalman filter (EKF) is a useful tool for structural parameter identification with limited observations. It is, however, not applicable when the excitations on the structure are unknown or the excitation locations are not monitored. A novel Extended Kalman filter approach referred to as the General Extended Kalman filter with unknown inputs (GEKF-UI) is proposed to estimate the structural parameters and the unknown excitations (inputs) simultaneously. The proposed GEKF-UI gives an analytical EKF solution dealing with the more general measurement scenarios with the existing EKF methods as its special cases. Existing constraints on sensor configuration have been removed enabling more general application to complex structures. Simulation results from a 3-storey linear damped shear building, an ASCE benchmark structure and a two-storey planar frame structure are used to validate the proposed method for both time-invariant and time-varying system identification. © 2015 Elsevier Ltd.

The capital investment in a marine construction vessel requires a number of decisions to be made in regard to the target market and technical capability of the vessel. Given the uncertain demand and breadth of the offshore market over the 20-year horizon for which a vessel is typically designed there is no certain answer only a range of answers. To make investment decisions of such complex nature, modeling of the market and vessel characteristic capacities can be used to provide investment sensitivity results. The paper will present how construction market data of past and future work is used to assess the market utilization and capability of a construction vessel of a given set of characteristics. The assessment is done using algorithms which allow a large volume of market data to be evaluated. The modeling tool can be used to predict supply and demand and available market share for a given class of vessel and given set of market data. This paper will discuss how the modeling techniques were employed to arrive at the business decision to invest in a Derrick Lay Vessel and a Reel Ship how the final technical specification was determined.
