Geology and structural evolution of the Tashota Deformation Zone and implications for orogenic gold mineralization
No full textThe Tashota Deformation Zone (TDZ) is a north-striking, ductile structure within the Onaman- Tashota Belt in the eastern Wabigoon subprovince of the Archean Superior Province in northwestern Ontario. The < 2700 Ma TDZ has never been studied in detail, despite its location along the boundary between a large batholith and Mesoarchean and Neoarchean volcanic rocks, its north trend in a belt where most ductile structures trend east-west, and the presence of orogenic gold mineralization. The TDZ is a high strain zone that formed along the batholith- volcanic rock boundary during the development of a dome-and-keel architecture in the central Onaman-Tashota Belt. During this deformation event, gold was emplaced along the TDZ contemporaneously with significant gold deposit formation to the south in the Beardmore- Geraldton Belt during syn-accretionary imbrication of volcanic and sedimentary rocks along the southern margin of the Wabigoon subprovince
Surviving the chaos of Covid-19: exploring the impact of the pandemic on the mental health and well-being of Northern Ontario nurses
No full textThe study addressed the impact of the Coronavirus-19 (COVID-19) pandemic on the
mental health of registered nurses (RNs) and registered practical nurses (RPNs) in Northern
Ontario. The research question was: The research question guiding this study was: What are the
perceived mental health impacts of COVID-19 on Northern Ontario registered nurses and
registered practical nurses working during the pandemic?
A total of 127 nurses provided qualitative comments which were analyzed following
Helvi Kyngäs et al.'s (2020) content analysis methodology, and the adapted Nursing Worklife
model guided the interpretation. The key theme was Surviving the Chaos of COVID-19 and was
supported by four themes and two subthemes: 1) Threats to Nurses’ Health and Well-being (with
sub-themes: a) threats to nurses’ mental and emotional health and b) threats to nurses’ safety), 2)
Cut Off from the Familiar, 3) Systemic Chaos, and 4) Navigating Diminished Supports and
Resources. The results highlighted concerns about nurses' mental health and adverse workplace
conditions, offering valuable insights for healthcare institutions to enhance working conditions
and address threats to nurses' health during future global health crises
Still waters run deep: mobilizing architecture through the art of quilting along the Lachine Canal
No full textThe nature of Montréal’s relationship with water and the way it is used is a direct
result of policies, technical decisions, and environmental transformation. Through
the greenifying of the post-industrial Lachine Canal as a National Heritage
Park, critical histories of residents, neighbourhoods, and industrial workers have
been neglected. Only through oral histories have their narratives lived on,
acknowledging a fraught yet rich and diverse history of Montréal’s industrial
era. Through the intersection of interdisciplinary theory and place-based
investigation, this thesis explores how architecture might utilize water as an agent
to challenge existing power structures to offer cultural inclusivity and stewardship.
The craft of quilting is used as a methodology for employing oral histories and
establishing a framework for equitable access to the Lachine Canal. The framework
is applied to one of the canal’s discarded industrial sites, addressing spatial injustices
and opportunities for community engagement within the realm of public space.Master of Architecture (M.Arch
Exploring indigenous and visible minority women’s access to preventive breast and cervical cancer screening in Canada: a narrative review
No full textCanada’s health care system is founded on the principles of need rather than ability to
pay, priding itself for its decentralized, publicly-funded health care system that provides firstdollar coverage for preventive services across all provinces and territories (Allin et al. 2020;
Kumachev et al. 2016). Despite best efforts through federal sharing and the indisputable
evidence for early preventive mammography and Pap smear screening, profound disparities are
found in service availability, utilization and accessibility for Indigenous and Visible Minority
women in Canada (Amankwah et al. 2009; Demers et al. 2015; Ferdous et al. 2020). The
purpose of this narrative review is threefold: to explore the incidence of breast and cervical
cancer amongst Indigenous and Visible Minority populations in Canada, to explore potential
barriers associated with the uptake of mammograms and Pap smear tests by these two
populations; and to explore achievable interventions to improve access to cancer preventive
services for Indigenous and Visible Minority women. This review uses the WHO Social
Determinants of Health framework (SDOH) (World Health Organization 2010) rooted in equity
to guide the review of the literature, and the Five Dimensions of Accessibility of Healthcare
Services (Levesque et al. 2013) to guide the thematic analysis of intervention models.
An initial literature search was conducted using Google Scholar and Science Direct
databases for articles published from 2000 to 2022, yielding 8,462 articles. After screening for
irrelevant titles, and non-Canadian studies, 97 publications remained. After 71 duplicates and
publications that did not meet the search criteria were removed, a manual search was performed,
yielding a total of 34 publications that were included in the narrative review. Of these 34 articles,
17 articles concerned Visible Minority populations and 17 articles, Indigenous populations. The
articles included in this review covered four provinces: (1) British Columbia, (4) Manitoba, (13) Ontario and (2) Quebec, with the remaining 14 referencing Canada as a whole. The studies
shared similar trends in breast and cervical cancer incidence and screening uptake for Indigenous
and Minority women, with Pap smear uptake being lower than the national threshold and
mammography uptake being lower in these populations compared to the rest of the Canadian
population. Through thematic analysis, the most common barriers influencing accessibility and
underutilization of preventive breast and cervical cancer were found to include socioeconomic
status, culture and communication, education, lack of appropriate health care providers, and
societal beliefs and attitudes towards cancer screening amongst both populations. Finally,
possible interventions were identified in the literature that may inform strategies to achieve more
equitable access to healthcare services tailored to Canada’s multicultural society.Master of Arts (MA) in Interdisciplinary Healt
Sensuous & sacred architecture as mediators of the psychedelic state
No full textSpurred by recent studies that attest to their
therapeutic benefits, psychedelic medicine is
experiencing a renaissance in scientific and
public reception. Founded on indigenous
ceremonial practices and the work of
pioneering researchers of the twentieth
century, today’s psychedelic therapists,
guides, and researchers apply the tenets of
set & setting by controlling for the influence
of mindset and physical context on attaining
consistent positive results from psychedelicassisted therapy. On the basis that the ideal
setting is not just a visually appealing space,
but one that positively engages all the senses,
a phenomenological design approach will be
employed in the psychedelic-assisted therapy
retreat proposed by this thesis. It draws from
the sensory richness of its remote, natural
surroundings, and maintains that quality
within its interiors. Sited in the Lawson
Quarry between Espanola and Little Current,
Ontario, the retreat would service rural
townships which are among the least served
by mental health resources.Master of Architecture (M.Arch
Capture of industrial CO2-rich off-gas through optimized cultivation of microalgae
No full textThe utilization of microalgae to treat carbon dioxide (CO2)-rich industrial off-gas has been suggested as
both beneficial for emissions reduction and economically favourable for the production of microalgal
products, such as lipids to produce biodiesel. Common sources of off-gases include coal combustion (2-
15% CO2), cement production (8-15% CO2), coke production (18-23% CO2) and ore smelting (6-7% CO2).
However, industrial off-gas also commonly contains other acid gas components (typically nitrogen
oxides (NOX) and sulphur dioxide (SO2)) and metals that could inhibit microalgae growth and
productivity.
To utilize industrial off-gas effectively in microalgae cultivation systems, a number of solutions have
been proposed to overcome potential inhibitions. These include genetic modification to improve specific
cellular characteristics, chemical additions, bioreactor designs and operating procedures, and
bioprospecting to identify suitable acid tolerant strains.
In all this work, one commonly overlooked consideration is the inoculation density of the microalgae
culture, which can have significant influence on growth, and possibly lipid production withing the cell.
This thesis examines inoculation density and the utilization of bioprospected (acidophilic or acid
tolerant) strains to combat the inhibitions caused by acidic conditions, simulating those created through
the addition of industrial off-gas.
Inoculation density optimization has shown to significantly affect the growth and biomass production of
microalgae. It was found that, for most microalgae strains tested, an inoculation density of 100 ml L-1
resulted in optimal growth and biomass productivity. It was, however, determined that there was no correlation between inoculation density and cellular lipid content. The most successful strain was a
bioprospected Coccamyxa sp. strain. While the inoculation density affects the growth, the extent is
clearly species dependent.
There is a growing need for CO2 capture, and results of this thesis lead to several possible future
directions for further development, including; development of an evaluation matrix for target
compounds, repeat experiments with direct application of industrial off-gas, analysis of lipid quality,
increasing volumes to test at pilot scale (and eventually, industrial scale), and direct testing of an
optimized cyclical harvest approachMaster of Applied Science (MASc) in Engineering Scienc
The effects of nutrition labels on information recall and label preference
No full textThroughout the twenty-first century, nutrition and nutrition labelling have played an
important role in healthy eating behaviours. The impact a nutrition label can have as a reliable
source of nutrition information to help consumers make knowledgeable choices for living a
healthy lifestyle has not yet been accepted within Canada. This could be due to the possibility
that the current nutrition label employed in Canada is not effective and that an improvement to
the label could also increase its use by consumers who want to make healthier choices. The
current study (available online) aimed to explore the relationship between different product
labels and consumer preference for a certain food label. A sample of two hundred participants
(separated into four groups) were included in the analysis; nutrition understanding and accuracy
of the Nutrition Facts Panel in portraying health information, label type preference and
nutritional information recall were each assessed to determine which label will help consumers
make healthier food choices. Overall, it was determined that the most preferred and effective
label was the Multiple Traffic Light label, very closely followed by the current Nutrition Facts
Panel. However, both the MTL and NFP label performed rather closely and should be considered
on par with each other in terms of preference and recall accuracy. In addition, it is important to
note the analysis showed that the current Nutrition Facts Panel is not completely effective in
communicating nutritional information to consumers. The relevance of these findings in terms of
nutrition labelling is outlined below, along with all considerations for future research.Master of Arts (MA) in Psycholog
Correlates of tapering initiation and success at an opioid agonist treatment program in Northern Ontario
No full textCurrently, there is limited research on the correlates of tapering initiation and success in opioid agonist treatment (OAT). This research is part of a community-based participatory research study conducted in collaboration with a First Nation to describe and identify the benefits and areas of improvement for a community-based OAT program in Wiikwemkoong Unceded Territory. The study utilized retrospective chart review data for all active clients seeking treatment at the community-operated opioid replacement clinic, Naandwe Miikan, between May 2014 and December 2019. The correlates in this study were education level, age, gender, start drug, start dose in morphine equivalent dose (MED), and clients’ number of children. Standard binary logistic regression was used to model the binary variables taper initiation and taper success. Models demonstrated that taper initiation and success were influenced by start dose in MED and start drug, respectively. There were no significant findings related to the sociodemographic correlates. The results from this study have assisted in reducing the substantial gap in knowledge surrounding correlates of taper initiation and taper success in a remote Northern Ontario setting. Findings also identified electronic record limitations that impede robust evidence-based practice at the community level to track the added value of various strengths-based, cultural and community services on clients’ well-being and recovery. Lessons learned identify the need for data sharing agreements across health and mental health services in future research using patient chart data to investigate potential correlates of tapering initiation and success in opioid agonist treatment programs
Sustainable placemaking in Suburbia
No full textThere has been a significant increase in housing development in the Greater Toronto
Area over the past fifty years, and all signs indicate that this will continue in the near
future. The unsustainable practices of suburban developments must be addressed.
This thesis will look at the history of suburban developments from post-war times
to current practices, with a focus on the lack of identity of a place, the loss of
ecosystems, and hyper-individualism. It will also look at ways to improve tomorrow’s
suburban developments through placemaking, energy-efficient design and
implementation of green technologies like Net Zero and district energy to manage
and reduce the energy consumed by these developments. The thesis will consider
these elements and practices to create a plan to lay the groundwork for the future
community development. The main design proposal of this thesis will be for phase
one of the plan, which focuses on creating a place and providing identity to the site.Master of Architecture (M.Arch
Engaging in effective crisis intervention in a mental health context
No full textMental health crises are prevalent throughout the Western context (Kane et al., 2017;
Rogers et al., 2019; Yeager & Roberts, 2015). This prevalence is influenced by the inadequacy
of mental health resources, those experiencing mental health crises left with little to no options in
recovery (Iacobucci, 2014; Kane et al., 2017; Kerr et al., 2010; Marcus & Stergiopoulos, 2022).
Thus, the law enforcement system has assumed the responsibility of crisis intervention,
influencing increasing rates of arrest, incarceration, injury, and fatalities throughout intervention
(De Shalit et al., 2022; Iacobucci, 2014; Kerr et al., 2010; Parent, 2011; Marcus & Stergiopoulos,
2022; Rogers et al., 2019). My advanced practicum was thus focused on identifying and
engaging with current approaches to mental health crises from social work, law enforcement, and
collaborative perspectives as observed at the Canadian Mental Health Association. Through my
advanced practicum, I attempted to identify challenges to these perspectives specific to crisis
intervention stratagem and worked to increase efficacy in exploring positive change. This
practicum also created space for the exploration of the chosen service user population,
identifying the importance and efficacy of crisis intervention among said population. This report
was guided by my ongoing reflection practices, working to identify and analyze both my
practical role and effective intervention strategies. This report was also guided by my chosen
theoretical basis, Strengths-Based Social Work, Crisis Theory/The Crisis Intervention Model,
and Critical Theory influencing my participation and analyzation of effective crisis intervention
