The score reliability of language performance tests has attracted increasing interest. Classical Test Theory cannot examine multiple sources of measurement error. Generalizability theory extends Classical Test Theory to provide a practical framework to identify and estimate multiple factors contributing to the total variance of measurement. Generalizability theory by using analysis of variance ...

There are several advantages to using task-based assessment to determine magnetic field exposures. Job title based assessment is the common approach. A worker’s job title, however, does not necessarily indicate the magnetic field exposure tasks a worker performs. Task-based assessment is more efficient in that there are fewer tasks required to cover a population than job titles. It is easier to...

In the present study, the reliability assessment of performance-based optimally seismic designed reinforced concrete (RC) and steel moment frames is investigated. In order to achieve this task, an efficient methodology is proposed by integrating Monte Carlo simulation (MCS) and neural networks (NN). Two NN models including radial basis function (RBF) and back propagation (BP) models are examine...

In a dynamic, information and technology-driven society, librarians can create new roles by assessing changes in their environment, the potential effect and ways to reposition themselves. Scenario building, literature reviews, situation analysis, speculation and forecasting may be used. Librarians have a good idea of what they can offer, but are often unable to reposition themselves in time. Re...

Advanced driver assistance systems (ADAS) are available on the market whilst the development of existing systems and new systems continues. Improving safety is one of the key purposes of these systems. ADAS would therefore be welcome to support overtaking manoeuvres, since these cause many fatal accidents each year. Before an ADAS could be developed that can assist drivers with overtaking a tho...

Extant query-based measures of situation awareness that require interruption of dynamic tasks can be inappropriate in certain work contexts. A candidate real-time query-based method, the situation present assessment method (SPAM), was used to examine participants’ situation awareness in simulated submarine track management. The simulation and situation awareness queries were based upon a goal-d...
