Acute Regulation of Vascular Tone by AMP-activated Protein Kinase in Arteries of Healthy, Hypertensive and Aged Rats
(University of Waterloo, 2011-12-21)Background, Rationale and General Purpose: Several seminal observations suggest that AMPK mediates vascular tone: 1) in endothelial cell culture and in vitro isolated protein experiments, activation of AMPK stimulates ... -
Adolescent Maternal Nutrition and Health in Uganda: Voices from the Community
(University of Waterloo, 2018-01-23)INTRODUCTION: Over one quarter of adolescent girls in rural Uganda and more than one fifth of them in the Busoga region of Eastern Uganda experience pregnancy and childbirth. These young mothers have disproportionately ... -
Age-related changes in the control of mediolateral dynamic stability during volitional and reactive stepping
(University of Waterloo, 2012-04-23)The high incidence of falls and fall-related injuries among Canadians over the age of 65 continues to be a key public health issue. As the current proportion of individuals within this cohort of the population is predicted ... -
The aging spine: The effect of cyclic loading, simulated degeneration and prolonged sitting on joint stiffness across age
(University of Waterloo, 2018-08-22)Background: Low back pain is estimated to have a lifetime prevalence as high as 84%, and both the severity and frequency of low back pain reporting have a dependency on age. The nucleus pulposus and annulus fibrosis of ... -
Analysis of Transcranial Doppler Ultrasound Waveform Morphology for the Assessment of Cerebrovascular Hemodynamics
(University of Waterloo, 2012-08-29)The use of transcranial Doppler (TCD) ultrasound for the assessment of cerebral blood flow velocity (CBFV) provides an indication of cerebral blood flow assuming the diameter of the insonated vessel remains constant. Studies ... -
Anticipatory planning in object manipulation: A cross-sectional investigation of children, young adults and older adults
(University of Waterloo, 2016-08-25)Over a series of five studies, this work aimed to investigate anticipatory planning in object manipulation across the human lifespan. Main objectives were to: (a) understand the influence of the movement context; (b) ... -
Aperture Crossing in Challenging Environments: An Examination of the Factors that Influence the Passability of Narrow Spaces
(University of Waterloo, 2016-04-13)In order to get to where we need to go, locomotion often involves walking through narrow spaces. Whether an aperture affords passage is thought to be determined by the body size/aperture size relationship. For normal, ... -
Application of interRAI Assessments in Disaster Management: Identifying Vulnerable Persons in the Community
(University of Waterloo, 2016-09-02)Background: Several studies have shown the increased vulnerability and disproportionate mortality rate among frail community dwelling older adults as a result of disasters. Parallel to an escalating number of disasters, ... -
Applying a Systems Thinking Approach to Health Care for Women & Children in the Flood Plains of Western Zambia
(University of Waterloo, 2022-09-16)At least half of the world’s population are reportedly unable to obtain essential health services with significant gaps being noted in sub–Saharan Africa and Southern Asia. Access to health services incorporates physical ... -
Applying the Allostatic Load Model to Investigate the Biological Embedding of Psychosocial Stress in Firefighters
(University of Waterloo, 2022-08-30)Overview Psychosocial factors are recognised as a significant source of stress in the workplace, and long-term exposure to such stressors may increase chronic disease risk through physiological wear and tear quantified ... -
Approaches to understanding and measuring women’s empowerment and its relationship with women’s and children’s dietary diversity in sub-Saharan Africa.
(University of Waterloo, 2020-04-02)Background Women’s empowerment has been identified as a key component of development policies since in many cases, there are existing and widening gender gaps in wellbeing including in access to improved nutrition ... -
Assessing the Intergenerational Effects of Maternal Exposure to Drought in Early Life Before and After Prenatal Supplementation and the Seasonality Effects on Birth Outcomes in Rural Malawi
(University of Waterloo, 2018-01-19)BACKGROUND Prenatal supplementation can positively influence birth outcomes by addressing and improving the nutritional status of infants in resource-poor settings. Nevertheless, evidence from historical disasters such ... -
Assessing Visitors' Satisfaction at Parks Canada Sites
(University of Waterloo, 2012-05-08)This study addresses the measurement of satisfaction. In doing so, it proposes a hypothetical conceptual framework for examining visitors’ satisfaction with their experiences in nature-based settings. Visitors’ overall ... -
Associations of Moral Disengagement, Passion, and Competitive Anger and Aggressiveness with Attitudes toward Performance Enhancing Drugs in Sport
(University of Waterloo, 2015-01-05)The main purpose of the study was to explore relationships between moral disengagement in sport and attitudes toward performance enhancing drugs. Additionally, the purpose was to explore specific mechanisms of moral ... -
Axial twist loading of the spine: Modulators of injury mechanisms and the potential for pain generation.
(University of Waterloo, 2008-05-26)There are several reasons to research the effects of axial twist exposures and the resulting loading on the spine. The lack of consensus from the limited work that has previously examined the role of axial twist moments ... -
Axial twist of the lumbar spine: Mechanical responses to twisted postures and potential factors for workplace injury
(University of Waterloo, 2017-08-24)While a link between magnitudes of spinal axial twist motions and the various modes of associated injury, pain reporting, and lost time claims has been tentatively established, there is need for greater investigation and ... -
A BI-CULTURAL ANALYSIS OF NIGERIAN CANADIAN IMMIGRANTS WITH RESPECT TO ACCULTURATIVE STRESS, COPING, EGO INVOLVEMENT AND PARTICIPATION IN LEISURE
(University of Waterloo, 2012-02-07)There have been few African studies that examined relationships between acculturation, a process where immigrants assimilate the culture of their host country, coping, acculturative stress and enduring involvement in ... -
A biomechanical investigation into the link between simulated job static strength and psychophysical strength: Do they share a “weakest link” relationship?
(University of Waterloo, 2011-01-17)Maximum voluntary forces and psychophysically acceptable forces are often used to set force guidelines for exertions as a means to protect against overexertion injuries in the workplace. The focus of this dissertation was ... -
