The proportion of elderly individuals in society is increasing dramatically, leading to an increase in the prevalence of age-related neurological disorders that affect the function of the frontal lobes and overall movement control. This thesis aims to evaluate ‘executive control’ and the underlying brain changes in normal versus abnormal aging processes using saccadic eye movement tasks. Tasks performed by subjects that probe executive control consist of antisaccades (generate a voluntary eye movement after inhibiting an automatic movement to a visual stimulus), and memory-guided saccades (generate eye movements to three previous remembered visual stimuli in the same sequence they were presented). Both of these types of saccades require good functioning behavioural control, which is subserved by areas in the prefrontal cortex. This thesis specifically characterizes the changes in oculomotor control related to aging, Huntington’s disease, mild cognitive impairment (amnestic), and Alzheimer’s disease. We also specifically examine the neural mechanisms related to behavioural control in the antisaccade task in aging. Together, the conclusions drawn from this thesis reveal that specific areas in the prefrontal cortex are involved in executive dysfunction in both normal and abnormal aging, but the patient groups studied have provided new understanding that different underlying brain substrates may be altering function in the frontal cortical areas, such as the basal ganglia and the hippocampus. / Thesis (Ph.D, Neuroscience Studies) -- Queen's University, 2011-04-28 13:44:32.25

Leadership research has generally overlooked the qualities of successful CEOs, instead focusing on other levels of management. This study sought to identify the personal qualities that made CEOs successful. A literature review identified that there were five qualities associated with success including philosophies about life, self and others, characteristics, leadership style, areas for improvement and lessons taken from experience. A Model of CEO Success is proposed based on these qualities and the relationship between them. / Successful CEOs and their key direct reports completed a questionnaire and participated in interviews to arrive at the conclusions drawn. Results indicated that successful CEOs demonstrated three philosophies and characteristics most associated with success: humanistic approach, achievement and proactive thinking. They demonstrated a varied leadership style but mainly humanistic, empowering, achievement oriented, participative and directive approaches. Areas for improvement were mainly related to the over use or under use of philosophies and characteristics associated with success including a need to empower, coach and involve more often; be more patient; more learning and self-awareness; manage performance more effectively; confront more; be firmer with others and balance. Lessons learnt from experience led to the acquisition and development of philosophies and characteristics most associated with success. The philosophies and characteristics most associated with CEO success share properties with other psychological constructs including positive core self-evaluations and the proactive personality. There was a high level of agreement between CEOs and direct reports which supported the connection between managerial self-awareness and CEO success. / Future research could determine the manner in which the qualities interact to create success and whether development of the area for improvement enhance success or not. / The results have practical implications for CEO recruitment, development and coaching and contribute to the understanding of CEO success by detailing qualities associated with success. / Thesis (PhD)--University of South Australia, 2005.
