We evaluated an affect sensitive version of AutoTutor, a dialogue based ITS that simulates human tutors. While the original AutoTutor is sensitive to students’ cognitive states, the affect sensitive tutor (Supportive tutor) also responds to students’ affective states (boredom, confusion, and frustration) with empathetic, encouraging, and motivational dialogue moves that are accompanied by appro...

Computer self-efficacy (CSE) has been successfully used in many studies as a significant predictor of individual performance and attitudes. However there have been ongoing criticisms concerning selfefficacy’s conceptual foundations as well as its measurement. In the IS field, there have been a number of studies in which the relationship between CSE and consequent behaviors or attitudes was weak...

The standard model for prediction using a pool of experts has an underlying assumption that one of the experts performs well. In this paper, we show that this assumption does not take advantage of situations where both the outcome and the experts' predictions are based on some input which the learner gets to observe too. In particular, we exhibit a situation where each individual expert perform...

The best predictor of current investment at the firm level is lagged investment. This lagged-investment e§ect is empirically more important than the cash-flow and Q e§ects combined. We show that the specification of investment adjustment costs proposed by Christiano, Eichenbaum and Evans (2005) predicts the presence of a lagged-investment e§ect and that a generalized version of their model is c...

This study investigates the significance of Rogers’ Diffusion of Innovations (DOI) theory with regard to the use of a Virtual Learning Environment (VLE) at the Royal University of Bhutan (RUB). The focus is on different adoption types and characteristics of users. Rogers’ DOI theory is applied to investigate the influence of five predictors (relative advantage, complexity, compatibility, triala...

Recent work in political economics has examined the positive relationship between legislative size and spending, which Weingast et al. (1981) formalized as the law of 1/n. However, empirical tests of this theory have produced a pattern of divergent findings. The positive relationship between seats and spending appears to hold consistently for unicameral legislatures and for upper chambers in bi...

Although many IT service management frameworks exist, we still have limited theoretical understanding of IT service quality within a broader nomological network. Building on recent conceptual work on the IT service climate construct, this study empirically establishes it as a predictor of IT service quality using survey data from both IT units and their clients. Also examined was a set of antec...
