BACKGROUND Cronbach's alpha is widely used as the preferred index of reliability for medical postgraduate examinations. A value of 0.8-0.9 is seen by providers and regulators alike as an adequate demonstration of acceptable reliability for any assessment. Of the other statistical parameters, Standard Error of Measurement (SEM) is mainly seen as useful only in determining the accuracy of a pass ...

[Purpose] The aim of this study was to examine the intra-observer reliability for Prechtl's General Movements Assessment in Taiwanese infants. This includes the global General Movements Assessment, the Optimality List for Preterm General Movements and Writhing Movements, and the Assessment of Motor Repertoire-3 to 5 Months. [Subjects and Methods] Fifty-nine videos of 37 infants were observed an...

The existence of software faults in safety-critical systems is not tolerable. The goals of software reliability assessment are estimating the failure probability of the program, θ, and gaining statistical confidence that θ is realistic. The paper presents practical problems and challenges encountered in an ongoing effort to assess and quantify software reliability of NASA’s Day-of-Launch I-Load...

Performance assessment is exceedingly considered a key concept in teacher education programs worldwide. Accordingly, in Iran, a national assessment system was proposed by Farhangian University to assess the professional competencies of its ELT graduates. The concerns regarding the validity and authenticity of traditional measures of teachers' competencies have motivated us to devise a localized...

Deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. In this paper, generation reliability is considered and a method for its assessment using intelligent systems is proposed. Also, because of power market and generators’ forced outages stochastic behavior, Monte Carlo Simulation is used for reliability evaluation. Generation relia...
