This study is motivated by, and proceeds from, a central interest in the importance of evaluating IS service quality and adopts the IS ZOT SERVQUAL instrument (Kettinger & Lee, 2005) as its core theory base. This study conceptualises IS service quality as a multidimensional formative construct and seeks to answer the main research questions: “Is the IS service quality construct valid as a 1 st ...

Despite the widely recognised importance of intellectual capital as a vital source of competitive advantage, there is still little understanding of how organisations actually combine their components to drive value. The purpose of this study is to examine the interrelationships among intellectual capital components within the Portuguese banking context by extending a study completed by Bontis. ...

This study was conducted to examine the hypothesis that organizational commitment and job involvement interact in the prediction of turnover (Blau & Boal, 1987). Prior work in this area has not incorporated a sufficiently broad definition of commitment, has omitted relevant covariates, and has utilized inappropriate estimation procedures (ordinary least-squares regression [OLS]). The presence o...

In this study, we proposed a research model to investigate the factors influencing users’ continuance intention to use Twitter. Building on the uses and gratification framework, we have proposed four types of gratifications for Twitter usage, including content gratification, technology gratification, process gratification, and social gratification. We conducted an online survey and collected 12...

Intention to knowledge sharing is a growing concern that has been largely discussed in extant literature using Ajzen’s theory of planned behavior (TPB). However, the studies have mostly neglected the influence of individual psychological needs of knowledge workers on intention to share knowledge. Combining the TPB with McClelland’s three psychological needs approach, the study aims at uncoverin...

We develop a fast algorithm for computing the “SVD-truncated” regularized solution to the leastsquares problem: minx ‖Ax − b‖2. Let Ak of rank k be the best rank k matrix computed via the SVD of A. Then, the SVD-truncated regularized solution is: xk = A † k b. If A is m × n, then, it takes O(mnmin{m,n}) time to compute xk using the SVD of A. We give an approximation algorithm for xk which const...
