From the beginning, a completed dissertation was the goal, but the real value was in the process, not the product. The dissertation demonstrates the ability of a researcher to complete a significant study, but only after the process provides the skills in conceiving and justifying a research idea, designing a study, collecting and analyzing the data, and finally reporting the results. The process was rewarding in its own right. I sincerely thank my advisor and committee chairperson, Dr. Gurvirender Tejay, for his direction, guidance, and focus. Dr. Tejay's steady and consistent mentorship gave me the confidence to follow a productive and purposeful path to completion. Committee members Dr. Steve Terrell and Dr. Michael Lane provided valuable support through the dissertation process, and created an environment that fostered learning and development. Your insight pushed me to learn beyond where I had set my own limits. I am especially grateful to my wife, Shirley, who encouraged and motivated me, while remaining patient and supporting as I hit the inevitable obstacles. You helped me strike the balance between steady progress and unproductive, wasted effort.

Hedonic information systems are those that are used primarily for pleasure. Previous research has established that the intention to use hedonic information systems is explained mainly by perceived ease of use and perceived enjoyment, with perceived usefulness to one's job being given less importance. Facebook could be seen as a hedonic information system. This paper employs a cross-sectional survey of 178 professionals who used Facebook to various degrees. Predictably, the authors' empirical results show that perceived enjoyment is indeed a much stronger determinant of intended continued Facebook use than ease of use or usefulness to one's job, explaining a considerable proportion of variance in continued use behavior. The authors also find that ease of use is a strong determinant of perceived enjoyment. Interestingly, their results suggest that intended continued Facebook use is significantly and positively associated with job performance, both directly and indirectly via job satisfaction.

This study investigated how external influences motivate senior management to commit to information system security (ISS) by examining the mediating role of senior management between external influences and organizational change. Neo-institutional theory was used to examine normative, mimetic, and coercive mechanisms that affect ISS assimilation in organizations. Findings show senior management beliefs about ISS and participation in ISS mediate effects of external influences on ISS assimilation. The findings from this pilot study give merit to a more comprehensive study, and provide a better understanding of how to motivate senior management to lead ISS in their organizations.
