With the shift in the medical education curriculum to a competencybased model, objective proficiency assessment is necessary. In this work, we use exploratory factor analysis to assess which primitive metrics convey unique information about proficiency in point-of-care ultrasound applications. We retrospectively validate the proposed methods on three datasets: FAST examination, femoral line, an...

The determinants of competitiveness between hub ports in the multipolar Northeast Asian system will decide which achieve regional gateway status. A survey instrument to assess 21 pertinent measurement items generated 203 responses from Shanghai, Hong Kong and Busan. Exploratory factor analysis revealed a valid and reliable competitiveness construct underpinning 19 measurement scales and a four-...

The purposes of this study were (a) to develop a valid and reliable questionnaire using both the structural characteristics of digital games and students perceptions of the concept of freedom of choice in digital games, (b) to validate items to be used in questionnaire to measure perceived freedom of choice, (c) to identify the factors that underlie freedom of choice in digital games and (d) to...

Previous researchers who have studied children’s spirituality have often used narrow measures that do not account for the rich spiritual experiences of children within a multi-faith context. In the current study, we describe the initial stages of development of a children’s spirituality measure, in which items were derived from children’s spiritual narratives. An exploratory factor analysis of ...

Several citation-based indicators, including patent h-index, have been introduced to evaluate the patenting activities of research organizations. However, variants developed to complement h-index have not been utilized yet in the domain of intellectual property management. The main purpose of this study is to propose new indices that can be used to evaluate the patenting activities of research ...

In the literature on achievement goals, performance-approach goals (striving to do better than others) and performance-avoidance goals (striving to avoid doing worse than others) tend to exhibit a moderate to high correlation, raising questions about whether the 2 goals represent distinct constructs. In the current article, we sought to examine the separability of these 2 goals using a broad fa...

The purpose of this paper is to explore the effects of business intelligence consumer needs, internal intelligence sources and external intelligence sources on the value of the business intelligence product as measured by the quality of decisions made by business intelligence consumers, the willingness of these consumers to confirm decisions already made and their ability to scan the external e...

To date, little research has been done on the role of emotions with respect to computer related behaviours. The purpose of this study was to develop a reliable, valid scale to assess emotions while learning with computers. Four emotions (anger, anxiety, happiness, and sadness), selected after a detailed review of the research, were evaluated. Internally reliability estimates were acceptable. Co...

Exploratory factor analysis is commonly used in IS research to detect multivariate data structures. Frequently, the method is blindly applied without checking if the data at hand fulfill the requirements of the method. In this paper, we investigate the influence of sample size, data transformation, factor extraction method, rotation and number of factors on the outcome. We compare classical exp...

The purpose of this paper was to demonstrate empirically that attitudinal loyalty and satisfaction are divergent concepts. The results of this paper indicate that attitudinal loyalty is satisfaction driven and that satisfaction and attitudinal loyalty are related but divergent concepts. However had the analysis relied exclusively on correlation or exploratory factor analysis the empirical resul...
