520    During organizational crisis, leaders and teams must 
       navigate an uncertain, important and urgent situation 
       cautiously and swiftly, as mistakes could result in dire 
       consequences for individuals, organizations and/or 
       society. The purpose of this dissertation was to examine 
       how leaders influence team members' affect, cognition, 
       resilience and performance in crisis and non-crisis 
520    Using a field quasi-experimental design, the current bed 
       shortage crisis at two large hospitals and 17 smaller 
       sites in Canada was studied. During this crisis, a bed 
       capacity of 130% was reached, hospital admissions took up 
       to four days, critically ill patients were sent to the 
       United States for treatment, and surgeries were cancelled 
       numerous times. Front-line health care leaders and their 
       team members (mainly nurses) participated in the study. 
       The organizational crisis condition included leaders and 
       their teams who were most affected by the bed shortage 
       crisis (32 leaders and 151 team members); the non-crisis 
       condition included leaders and teams who were not facing 
       the bed shortage crisis (39 leaders and 255 team members) 
520    The findings revealed that during crisis, as compared to 
       non-crisis situations, there was higher active management-
       by-exception leadership, negative affect, positive affect,
       and performance. There was less perceived expertise of the
       leader during crisis, as compared to non-crisis. In crisis
       and non-crisis, team members' core self-evaluations were 
       positively associated with positive affect and resilience,
       and negatively associated with negative affect. During 
       crisis, core self-evaluations were positively related to 
       performance. Positive affect was positively associated 
       with resilience and performance in crisis and non-crisis. 
       In contrast, team members' negative affect was negatively 
       related to resilience in crisis and non-crisis 
520    Tests of multilevel hypotheses using hierarchical linear 
       modeling showed that in non-crisis, both transformational 
       and active management-by-exception leadership were 
       positively related to positive affect. During crisis and 
       non-crisis, transformational leadership was negatively 
       associated with negative affect. Implications are drawn 
       for academics and practitioners
