While software is so important for all facets of the modern world, software development itself is not a perfect process. Agile software engineering methods have recently emerged as a new and different way of developing software as compared to the traditional methodologies. However, their success has mostly been anecdotal, and research in this subject is still scant in the academic circles. This...

It is first pointed out that most often used reliability coefficient α and one-factor model based reliability ρ are seriously biased when unique factors are covariated. In the case, the α is no longer a lower bound of the true reliability. Use of Bollen’s formula (Bollen 1980) on reliability is highly recommended. A web-based program termed “STERA” is developed which can make stepwise reliabili...

Previous research on individual differences in the acoustic structure of vocalizations and vocal recognition has largely focused on the contexts of parent-offspring interactions, territory defense, sexual interactions, and group cohesion. In contrast, few studies have examined individual differences in the acoustic structure of mobbing and alarm calls. The purpose of this study was to explore i...

In the 21 st century, learners will need a different set of life skills and competencies in order to be successful in life, and at the same time contribute positively to society at large. In equipping learners with the necessary skills and attitudes, teachers play a pivotal role. They are the gatekeepers of the curriculum (Eisner, 2002) and inevitably they transmit values in the course of their...

The traditional approaches of modeling and estimation of highly skewed deposits have led to incorrect evaluations, creating challenges and risks in resource management. The low concentration of the rare earth element (REE) deposits, on one hand, and their strategic importance, on the other, enhances the necessity of multivariate modeling of these deposits. The wide variations of the grades and ...

OBJECTIVE The objective of this study was to compare the diagnostic role of features reflecting the geometry of clusters with features reflecting the shape of the individual microcalcification in a mammographic computer-aided diagnosis system. MATERIALS AND METHODS Three hundred twenty-four cases of clustered microcalcifications with biopsy-proven results were digitized at 42-microm resolutio...
