There are four free base types of CKs found in higher plants, trans-zeatin (tZ), N6-(∆2-isopentenyl)adenine (iP), cis-Zeatin (cZ) and dihydrozeatin (DZ). CK biosynthesis is regulated by adenosine phosphate-isopentenyltransferase (IPT), which is encoded by a multi-gene family… more Full Text: THE REGULATION OF CYTOKININS DURING KERNEL DEVELOPMENT IN HIGH AND LOW YIELDING OAT AND BARLEY LINES A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the requirements for the Degree of Master of Science in the Faculty of …

Abstract: <p>The study aimed to examine the association between different components of executive function (EF) and emotional, behavioural, and social competence problems (EBSP) in children with epilepsy. Although there is evidence of an association between EBSP and EF in typically developing children, little research has examined this relation in children with epilepsy. The sample comprised of 42… more Full Text: EXECUTIVE FUNCTION AS A PREDICTOR OF EMOTIONAL, BEHAVIOURAL, AND SOCIAL COMPETENCE PROBLEMS IN CHILDREN WITH EPILEPSY A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Degree of Master of Science in the Faculty of Arts …

Abstract: <p>The predator vs. prey dynamic is an omnipresent factor in ecological systems that may drive changes in life history patterns in prey animals through behavioural, morphological, and physiological changes. Predation risk can have profound effects on the life history events of an animal, and is influenced by the neuroendocrine stress response. Activation of the hypothalamic-pituitary-… more Full Text: TIME-DEPENDENT EFFECTS OF PREDATION RISK ON STRESSOR REACTIVITY AND GROWTH IN DEVELOPING LARVAL ANURANS (Lithobates pipiens) A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of …

Abstract: <p>This thesis explores the social history of the Marange people of eastern Zimbabwe from the 1960s to 2015. It uses historical episodes like the recurring droughts, the 1970s war of independence, the 'crisis in Zimbabwe,' that has been traced from the late - 1990s, and the diamond mining story to demonstrate how the inhabitants interacted with their environment. It argues that… more Full Text: ‘Land, Displacement and Coping Strategies’: A Social History of the Marange People, Eastern Zimbabwe, 1960s -2015 A Thesis Submitted to the Committee on Graduate Studies In Partial Fulfilment of the Requirements for the Degree of Master of Arts In the …

Abstract: <p>This thesis offers a comprehensive look at the changing roles of a colonial built railway in what is now eastern Botswana. It was built for the extraction of mineral wealth and migration of cheap African labour in Southern Africa but it later assumed a different role of shaping the modern Botswana state.

Abstract: <p>Men who become fathers undergo a transitional period during which they adjust to their new role as the caregiver of a child, a time that is usually viewed as a major life transition (Lamb, 2010). Much of the published literature focuses on fathers with identified issues (e.g., divorced fathers); therefore, there is a need for research that looks at the experiences of more typical fathers… more Full Text: THE FATHERING EXPERIENCE OF THE TRANSITION INTO PARENTHOOD A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY …

Abstract: <p>Previous research has suggested that childhood sensory sensitivity may predict adult obsessive compulsive (OC) behaviours. To date, however, research has not addressed how the separate dimensions – harm avoidance and incompleteness - may influence this relationship or why it exists. The current study used a retrospective design to test a) if sensory sensitivity in childhood predicts… more Full Text: CHILDHOOD PRECURSORS OF ADULT TRAIT INCOMPLETENESS A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of the Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, …

Abstract: <p>In this work, various aspects of neural networks, pre-trained with denoising autoencoders (DAE) are explored. To saturate neurons more quickly for feature learning in DAE, an activation function that offers higher gradients is introduced. Moreover, the introduction of sparsity functions applied to the hidden layer representations is studied. More importantly, a technique that swaps the… more Full Text: SPAF-network with Saturating Pretraining Neurons A Thesis Submitted to the Committee of Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science TRENT UNIVERSITY Peterborough, …
