Kalman filtering has been widely considered for dynamic state estimation in smart grids. Despite its unique merits, the Kalman Filter (KF)-based dynamic state estimation can be undesirably influenced by cyber adversarial attacks that can potentially be launched against the communication links in the Cyber-Physical System (CPS). To enhance the security of KF-based state estimation, in this paper...

Cyberloafing is the personal use of the Internet by employees while at work. The purpose of this study is to examine whether employee job attitudes, organizational characteristics, attitudes towards cyberloafing, and other non-Internet loafing behaviors serve as antecedents to cyberloafing behaviors. We hypothesize that the employee job attitudes of job involvement and intrinsic involvement are...

Expectancy value theory holds that goal-directed behavior is a function of (a) expectations—the belief that performance depends on effort, (b) instrumentality—the belief that outcome depends on performance, and (c) outcome value—the value attached to achieving the outcome. The present research provides a direct test of two factors involved in the instrumentality component: the contingency betwe...

This paper presents a study of electronic brainstorming (EBS) that begins with theory building, tool development, and experimentation, and ends with practical guidance for facilitators and developers. The paper argues that social loafing impairs the productivity of EBS groups, and that social comparison is a way to decrease the effect{s) of social loafing. The literature on brainstorming produc...

Using the American Time Use Survey (ATUS) 2003-12, we estimate time spent by workers in non-work while on the job. Non-work time is substantial and co-varies positively with the local unemployment rate. While the fraction of workers who spend some time in non-work varies pro-cyclically, the average time spent by workers in non-work conditional on any positive non-work varies countercyclically. ...
