OBJECTIVE To determine the prevalence of confirmatory use of spirometry in patients admitted to a tertiary-care facility with the diagnosis of chronic obstructive pulmonary disease (COPD), including those with respiratory failure, and compare that to the use of confirmatory 2-dimensional echocardiography (2-D echo) in patients admitted with the diagnosis of congestive heart failure (CHF), to de...

This article explored the effect of resource-based capability and inter-organizational coordination on a firm’s supply chain management focus. We proposed a conceptual framework to describe these two sets of antecedents. The hypotheses were tested using confirmatory factor analysis and multiple linear regression on a set of data collected in the U.S., Europe, and New Zealand. Test results revea...

The paper reports results from a pilot study into marketing assets and capabilities. Empirical work conducted in the UK and Austria is used to test a set of items for measuring these marketing resources using confirmatory factor analysis. The resulting scales are both conceptually and empirically validated and shown to offer excellent levels of reliability.

Nucleic acid amplification tests offer superior sensitivity for the detection of Chlamydia trachomatis infection, but many laboratories still use nonamplification methods because of the lower cost and ease of use. In spite of their availability for more than a decade, few studies have directly compared the nonamplification tests. Such comparisons are still needed in addition to studies that dir...

This study attempts to validate the consumer-oriented criteria list, developed by Wang et al. (2010), for selecting online travel shopping sites. Based on a sample of 985 respondents, confirmatory factor analysis was employed to test the factor structure and assess the reliability and validity of the list. The results support the list developed by Wang et al. (2010) and claim the list can be fu...
