    The missing link: An examination of safety climate and clinical outcomes in a national sample of hospitals
    (2007-04-30) Lyon, Julie Stella; Hanges, Paul J; Psychology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    This dissertation examined the effect of safety climate on caregiver and patient safety outcomes in a national sample of hospitals. Hypotheses testing climate level and climate strength were not supported for caregiver injuries and postoperative patient outcomes. The main contribution of this dissertation was to test whether the system of care--as evidenced by the patterns of safety climate in multiple units--was related to patient harm. The pattern of safety climate across units within hospitals predicted compliance with procedures for treating heart failure and pneumonia patients over and above the effect of safety climate elevation and variability. In addition, variability in safety climate between units in hospitals was related to lower compliance with procedures for treating heart attack patients. The sample consisted of caregiver survey data collected from 59 hospitals that belonged to a non-profit hospital system in the United States.

    Does Distant Leadership Make a Difference? Exploring the Effects of Leadership and Substitutes for Leadership on Virtual Worker Performance and Satisfaction
    (2003-11-25) Lyon, Julie Stella; Schneider, Benjamin; Psychology
    Virtual work, or working from a site other than the main office, has been receiving a great deal of attention in recent years. What has not received the attention it deserves is the role of the virtual worker's leader. In the present study I tested a framework for understanding a virtual leader's influence on the subordinate outcomes of performance and satisfaction. I also included several of the variables suggested by the literature on substitutes for leadership (Kerr & Jermier, 1978). Employing a lab study framework, I crossed three levels of leadership (transactional, transformational, and no leadership) with three categories of leadership substitutes (conscientiousness, feedback, and climate for well-being). The effect of leadership on performance quantity was significant, with participants in the transactional condition outperforming participants in the transformational condition. Additionally, interesting interactions emerged between leadership and feedback and between leadership and conscientiousness on performance. Limitations and implications are discussed.
