The psychometric analysis of the sexual machismo scale in Peruvian context was carried out by employing confirmatory factor a sample 2470 university students from public city Arequipa. consisted 1235 randomly selected males and females. 12-item Sexual Machismo Scale, which has been previously developed validated other contexts, used. results indicate unidimensional structure that there are mini...

Cut scores are test scores used in mastery testing and in certification tests to identify those test takers who appear to have achieved at a predetermined level of proficiency. Cut scores are often used to differentiate test takers on a passfail basis. This paper takes up points raised by Berk (2000), discussing the use of reliability and error indices which are particularly appropriate for tes...

In the current study, we introduce the Item-Specific Deficit Approach (ISDA), a novel method for characterizing memory process deficits in list-learning data. To meet this objective, we applied the ISDA to California Verbal Learning Test (CVLT) data collected from a sample of 132 participants (53 healthy participants and 79 neurologically compromised participants). Overall, the ISDA indices mea...

TIMSS collects a vast amount of information aimed to provide a context to better understand education systems around the globe. This paper discusses how this background information can be reported using three real examples from the 1999 assessment. These examples illustrate the main concepts and steps involved in reporting background data, while presenting methods and statistical techniques tha...

This article reviews conventional and novel methods for facial-image identification from forensic aspects. Among the conventional approaches, three methods, i.e., morphological comparison of facial features, anthropometric indices comparison, and face-to-face superimposition, are generally used. The methods most commonly used in caseworks are in the order of morphological comparison, anthropome...

Multiple M-mode echocardiographic indices of left ventricular function are currently in use, but their reliability is disputed. Therefore, we correlated echo ejection fraction (EF) using quadratic (Q) and cubic (C) formulae, percentage of minor axis shortening (%S), mean velocity of circumferential fiber shortening (mVCF), and peak VCF with angiographic EF in 37 subjects, including 10 normal su...

This paper studies supply chain repairable system with a number of the same type of independent parts suppliers and the single demander. Suppose that the supply time of the component suppliers has exponential distribution, and the repair/restore time after the supply break has general continuous distribution. Using supplementary variable method, generalized Markov process theory and the Laplace...

Several indices of component importance have been proposed in the literature. The index most relevant to system reliability is the Birnbaum importance, but a comparison between two components is hard to prove and even hard to verify by computation. In this paper we propose a new index which is stronger than the Birnbaum comparison, but always veri0able by computing. In many cases, it could even...

Generally, the failure rate and the repair time of system components are constant parameters in reliability assessment of electric distribution systems. A failure of component is resulted from failing in the operation or overloading. In addition, there exist cases where, the repair times of components are small and tolerable from customer point of view. Thus, tolerable repair times may be overl...

Channel-Coded Optimal Estimation (CCOE) is an algorithm which combines sourcestatistics, bit-reliability informations at the channel output and the redundancy introduced by some channel code to compute the a-posteriori probabilities of the possibly transmitted source-encoder indices at the receiver. A recursive formula for the computation of the a-posteriori probabilities is derived and some sp...
