Estimating software development cost with high accuracy is still a largely unsolved problem. Consequently, there is ongoing, high activity in this research field; a large number of different estimation models ranging from mathematical functions to arbitrary function approximators (AFA’s) have been proposed over the last 20+ years. Unfortunately, the studies do not converge with respect to the q...

The main aim of this chapter is to introduce the reader to the concept of testing and to the principles that underpin the practice of educational and psychological testing. The first part of this chapter is devoted to that aim. A second aim of the chapter is to examine applications of testing under the headings of educational, industrial, and clinical. Examples will be introduced from the autho...

BACKGROUND The purpose of this study was to examine the psychometric properties (validity and reliability) of Persian version of the 25-item Caring Dimension Inventory (CDI-25). MATERIALS AND METHODS A psychometric instrument validation study was designed. Content validity, internal consistency, and stability were confirmed. A total of 288 participants (143 nurses and 145 nursing students) we...

Integrity tests have become a prominent predictor within the selection literature over the past few decades. However, some researchers have expressed concerns about the criterion-related validity evidence for such tests because of a perceived lack of methodological rigor within this literature, as well as a heavy reliance on unpublished data from test publishers. In response to these concerns, ...

BACKGROUND Since simulators offer important advantages, they are increasingly used in medical education and medical skills training that require physical actions. A wide variety of simulators have become commercially available. It is of high importance that evidence is provided that training on these simulators can actually improve clinical performance on live patients. Therefore, the aim of th...

Within the EURopean micronutrient RECommendations Aligned Network of Excellence (EURRECA), a scoring system was developed to assess the quality of dietary intake validation studies. The scoring system included three steps. The first step was to give each study a quality score, which included five components: sample size, statistics used, data collection procedure, consideration of seasonality a...

Increasing the performance of computing system today means more parallelism. Systems are becoming multi-cores. The on-chip interconnect is a complex infrastructure having a crucial impact on the system global performance and functionality. In this draft paper we present recent results and work-in-progress towards a general compositional approach for the validation and verification of networks-o...

In this paper we present the methodology of data collection and implementation of databases for the creation of extensive lexical and terminological resources for the Greek Sign Language (GSL) in order to introduce the major issue of dynamic sign representation. In respect to electronic linguistic resources of GSL, the focus is on issues of validation of linguistic content, multipurpose design ...
