We conceptualize two distinct post-acceptance usage behaviors: (1) routine use (RTN) refers to the use of information system (IS) consistent with normal work processes and (2) innovative use (INV) means users’ applying system features in novel ways. While RTN helps integrate the implemented IS into work processes, INV further extracts the value of the IS. Drawing on motivation theory, we propos...

In this paper we present new empirical evidence on the agency based asset pricing model of Brennan (1993). We find strong evidence that in the recent period stocks whose returns covary more with the idiosyncratic component of the S&P500 return have significantly lower returns, holding constant either the market beta or the loadings on the Fama-French factors. The effect is confined mainly to la...

Fama (1970) defined an efficient market as one in which prices always ’fully reflect’ available information. This paper formalizes this definition and provides various characterizations relating to equilibrium models, profitable trading strategies, and equivalent martingale measures. These various characterizations facilitate new insights and theorems relating to efficient markets. In particula...

The purpose of this study was to investigate the effect of inspiratory muscle (IM) warm-up on performance and locomotor muscle oxygenation during high-intensity intermittent sprint cycling exercise. Ten subjects performed identical exercise tests (10 × 5 s with 25-s recovery on a cycle ergometer) after performing one of two different IM warm-up protocols. The IM warm-up consisted of two sets of...

Methods Primary observational data were collected on 280 inpatient admissions that: (1) had a primary diagnosis of ischemic heart disease, acute cardiovascular (CV) disease, or other forms of heart disease, and (2) were seen by IM staff at Abbott Northwestern Hospital. IM providers collected data before and after each treatment session; primary outcomes were pre and post-treatment pain and anxi...
