Observations of turbulence and mixing in the southeastern Beaufort Sea

Benjamin Scheifele
In this thesis, I use a novel set of hydrography and turbulence measurements from the southeastern Beaufort Sea to i. compare estimates of the turbulent kinetic energy dissipation rate, ε, obtained independently from shear and temperature microstructure measurements; ii. characterize turbulence and mixing in the Amundsen Gulf region of the southeastern Beaufort Sea; and iii. describe the characteristics of tracer diffusion in an oceanic flow as it transitions between fully turbulent and nearly-laminar. I collected...

A team-based model of care : qualified exercise professionals and the impact on aging health

Nadine Sinnen
Background: Physical inactivity is a rising global concern as it relates to the risk of non-communicable diseases (NCD) and associated burden on health care. Failure to incorporate 150 minutes per week of physical activity (or 15-30 minutes per day) has been shown to increase the risk of NCDs such as cancer, heart disease, stroke, and diabetes by 20-30%, and decreases longevity by 3-5 years. The importance of 15-30 minutes of physical activity should no longer...

Syilx health and well-being in palliative care

Our Children’s Health v. Public Education in 21st Century America

Douglas Selwyn
What would schools and communities look like if the health and well-being of all our children were our highest priorities? More important than test scores, profits, or real estate values? What actions would we take if we wanted to guarantee that all our children were growing up with what they needed to be healthy, happy, and successful—and not just some of them? The United States was once among the healthiest countries in the world. As...

Apical vapor lock effect in conservative Ni-Ti instrumentation using V-taper rotary system

Veselin Trifonov
Aim: The presence of apical vapor lock during irrigation has been shown to have a negative impact on debris and smear layer removal. The aim of this study was first, to compare apical vapor lock formation during positive pressure syringe irrigation following conventional, ProTaper Gold and conservative, V-taper nickel-titanium instrumentation. The second aim was to evaluate effectiveness of apical vapor lock elimination by sonic, ultrasonic and manual dynamic agitation, once established. Methods: Thirty-six single rooted...

Changes in the livelihoods of people in protected areas in China in the past 40 years : based on Jiuzhaigou and Shennongjia Protected Areas

Weiye Wang
The use of Protected areas (PAs) is an effective approach for conservation worldwide. The support of local communities has significant influence on the success of conservation areas. This research provides further insights into the livelihoods of people living in PAs. It examines the perspectives of local villagers on the establishment of PAs and the development of associated tourism industries. I used a case study approach to conduct an in-depth examination of two PAs in China....

Possibility in groups : examining group interventions to enhance emerging adults' possible selves

Zarina Alexandra Giannone
Emerging adulthood is a period when a person’s sense of who one can become undergoes considerable development. It has been proposed that interventions that focus on enhancing identity can help emerging adults shape and pursue their life goals; however, little is currently known about group interventions that help young people develop a robust sense of identity. Thus, the purpose of this dissertation was to advance understanding of identity-focused group interventions among emerging adults. Three studies...

In vitro and ex vivo exploration of knock-in mouse models harboring mutations linked to late onset Parkinson’s disease

Igor Tatarnikov
Parkinson’s disease (PD) is the second most common neurodegenerative disorder, affecting 2-3% of the population aged 65 or older. Most PD cases are idiopathic i.e. without identifiable cause. Currently, therapeutic options for PD, which include dopamine replacement and deep brain stimulation, manage motor symptoms relatively well immediately following diagnosis. Unfortunately, neither therapeutic strategy modifies the progression of the disease or address the plethora of non-motor symptoms. Historically, PD was thought of as a disease of...

The study of epidemic and endemic diseases using mathematical models

Jummy Funke David
Mathematical models used in epidemiology provides a comprehensive understanding of disease transmission channels and they provide recommendations for methods of control. This thesis uses different mathematical models (direct and indirect transmission models) to understand and analyze different infectious diseases dynamics and possible prevention and/or elimination strategies. As a first step in this research, an age of infection model with heterogeneous mixing and indirect transmission was considered. The simplest form of SIRP epidemic model was introduced...

An ensemble automatic modulation classification model with weight pruning and data preprocessing

Xueting Yang
Automatic Modulation Classification (AMC) detects the modulation type and order of the received signal using limited prior knowledge within a short observation interval. In this thesis, we aim to provide a computation-efficient and high-performance AMC model for resource-constrained mobile devices. We use a public RadioML dataset and introduce three data pre-processing methods including noise reduction, normalization, and label smoothing before training the raw signals. Besides four common signal representations, we propose a new signal representation...

Journeying with abeyance : a Welsh cultural approach to contemplative connection with the living world

Joanne Price
As a response to climate change, this dissertation attends to a Welsh cultural approach to contemplative connection with the living world. In it, I write with auto-ethnography to explore my own cultural background, and relationship with trees and ancestral characters. Trees are vital to this journey with abeyance, a word I first heard when walking in the rainforests of the Pacific Northwest. Learning that abeyance originated in Wales where I am from, I retreat to...
