TL;DR: In this paper, a study on the reliability evaluation of earth slopes under a probabilistic framework is presented, where the geomechanical parameters of the slope system have been treated as random variables for which different probability distributions have been assumed.
Abstract: This chapter pertains to a study on the reliability evaluation of earth slopes under a probabilistic framework. This study is concerned in the first phase with the determination of reliability index and the corresponding probability of failure associated with a given slip surface and then in the second phase with the determination of the critical probabilistic slip surface and the associated minimum reliability index and the corresponding probability of failure. The geomechanical parameters of the slope system have been treated as random variables for which different probability distributions have been assumed. The reliability analyses have been carried out using two methods, namely, the approximate yet simple mean-value first-order second-moment (MVFOSM) method and the rigorous first-order reliability method (FORM). Based on a benchmark illustrative example of a simple slope in homogeneous soil with uncertain strength parameters along a slip circle, an effort has been made to numerically demonstrate the nature and level of errors introduced by adopting the MVFOSM method for reliability analysis of earth slopes still widely used in the geotechnical engineering practice, vis-a-vis a more accurate method such as the FORM.

TL;DR: Step tests can assess exercise tolerance, only require a small space and are simple, safe and low cost, which means that reference values are rare.
Abstract: Exercise testing is a valuable tool for assessing the cardiorespiratory and functional capacity of healthy children (1). Step tests can assess exercise tolerance, only require a small space and are simple, safe and low cost (2). Few studies have evaluated the validity and reliability of step tests in healthy children, which means that reference values are rare (3).

TL;DR: The objectivity of the tested peer review procedure seems definitely higher than in American studies of peer review of hospital charts, and the coefficients of interrater reliability, intrarater reliability and reviewer bias range from sufficient to good.
Abstract: In Germany the statutory pension insurance institutions have started a quality assurance programme. Our institute developed a peer review procedure for screening the process quality of rehabilitation care. The peer review was tested in a pilot study. Our article refers to the examination of interrater reliability, intrarater reliability and reviewer bias. First of all, experienced doctors were trained in reviewing reports routinely written by rehabilitation doctors at discharge of their patients. The peers had to judge on 56 process criteria belonging to six categories (e.g. case history). The reliability coefficients were calculated for the overall judgemant of each category and the overall judgement of the process quality of rehabilitation care. The coefficients of interrater reliability and the coefficients of average intrarater reliability range from sufficient to good. Only few reviewers showed a general tendency to harsh or lenient rating. The objectivity of the tested peer review procedure seems definitely higher than in American studies of peer review of hospital charts.
