The University of Ottawa (UO) has been dealing with a mental health crisis. The purpose of this study was to evaluate UO students’ knowledge, awareness, and use of mental health services (MHS) and to address limited research on knowledge of on-campus MHS. A cross-sectional online, bilingual, survey was administered to 235 UO students over 18 years old and registered at the university since Fall 2019. Data analysis included descriptive data, categorical analysis, and inductive thematic analysis. Awareness and use of services varied depending on the services in question. 48.9% of students only heard about the services but could not explain them. 57.4% would use a service if in distress and those who would not mainly point to Use of other methods and Lack of information as their reasons. This study contributes to the ongoing efforts of improving UO community’s mental wellbeing.

This study uncovered the pattern and spatial relationships between socio-economic factors and aggregated COVID-19 rates in Ottawa, Canada, from July 2020 to December 2021 at the neighbourhood scale. Both top-down and bottom-up data mining approaches were used to predict COVID-19 rates. The top-down approach employed ordinary least squares regression (OLS), spatial error model (SEM), geographically weighted regression (GWR) and multi-scale geographically weighted regression (MGWR). Model intercomparison was also undertaken. The pattern of COVID-19 in Ottawa exhibited a significant moderately positive spatial structure among neighbourhoods (Moran's I = 0.39; p = 0.0001). Local Moran's analysis identified areas of low and high COVID-19 clustering, interspersed with cold spots. The OLS model used determinants based on a literature review. Determinants were tested for normality using the Shapiro-Wilks test with those that failed the test had transformatoins to normality applied. Next, an OLS-based backward stepwise approach was used to select the optimal set of determinants based on goodness of fit, selecting the model with the lowest Akaike Information Criterion (AIC). The percentage of people who take public transit to work, percentage of people with no high school diploma, percentage of people over 65 years old, and percentage of people with a Bachelor level degree or above comprised the final set of determinants. A SEM model was created to account for residual spatial autocorrelation in the OLS model's residuals and yielded an adjusted R² = 0.63. Based on the SEM, a one-unit increase in the square root of the percentage of people with a bachelor's degree or above was associated with a 3.2% increase in COVID-19 rates, while the same unit increase in the square root of the percentage of people with no high school diploma was associated with a 10.6% increase in COVID-19 rates. Conversely, a one percent increase in the percentage of people aged 65 and older was linked to a 34.6% decrease in COVID-19 rates. To examine local variations in the relationships between the determinants and COVID-19, a MGWR with a Bisquare kernel and an adaptive bandwidth was used to improve upon the overall explained variance of the SEM model. The residuals of the MGWR model exhibited no significant spatial autocorrelation (Moran's I = -0.04; p = 0.62) and residuals were approximately normal (W = 0.98; p > 0.25). The MGWR model yielded an adjusted R² = 0.75. Taking a data mining and bottom-up approach, an optimized Random Forest model provided a very different set of determinants as important when compared to the top-down regression approaches and accounted for 47.34% of the COVID-19 variance.

« Sous le Canada Uni de 1841, Londres refusait le "self-government" au Québec, avec ou sans l'appui du clergé et des seigneurs. Les questions de l'autonomie coloniale, de la défense des droits nationaux et de la modernisation administrative refont surface après 1867 et continuent de préoccuper toute une élite de journalistes et de politiciens. Le processus juridique de la fédération canadienne reproduit en partie à l'ère du rail les traditions antérieures à travers les rivalités socio-politiques, précisément en ce projet de voie ferrée, dont nous avons l'intention d'établir plus qu'un simple bilan. […] La carence des capitaux privés, dans le projet montréalais, et la participation, plus que médiate, de l'élite gouvernementale, donnaient un premier indice à la présence d'une société pré-capitaliste. En outre, la campagne qui entourait la grande ville et qui se révélait étendue et de bonne organisation par ses paroisses établies depuis un siècle ou deux, préservait la région de la FE capitaliste-marchande, qu'aurait caractérisée l'aire du contado. Fossaert, en effet, cite Rhodes, Venise et Gênes comme exemples de cette société. Il s'agissait bien là, non pas du territoire fertile par ses terres riveraines à la tête du Saint-Laurent, mais de simples comptoirs dans le commerce international. Il ne reste plus qu'à regarder vers la seule FE demeurée probable : la société domaniale-marchande. […] Le projet du Montréal-Occidental apparaît surtout à l'observateur comme sous un double aspect : d'un côté, il cherche à s'intégrer aux réseaux du Grand-Tronc et du Pacifique-Canadien; de l'autre, il entend demeurer lui- même, fidèle à son plan initial et dans la poursuite de ses objectifs. Cette tendance à droite et à gauche projette comme une ombre au tableau mais laisse en même temps filtrer une lueur très utile dans une juste répartition des chapitres. Le partage s'opérera en quatre divisions bien distinctes : la situation du projet (4,1), sa localisation précise par l'idéologie régionale (4,2), l'influence qu'il reçoit de l'idéologie continentale (4,3) et, en dernier lieu, la médiation qu'exerce l'idéologie nationale sur le territoire entre les deux autres idéologies (4,4). »--pages 1, 9, 12

There are over one thousand closed ‘small’ landfills in Ontario, each with differing circumstances and potential problems. This project proposes a method of addressing such dormant sites in situ, based upon a case study in Hamilton. Of the four closed landfills within Hamilton city limits, three of them lie in the low lands of the Red Hill Creek Valley. Perched at the source of the Red Hill Creek, the Upper Ottawa Street Landfill introduces unspoken toxins into the ecosystem of the entire valley. As the storm water catchment for the escarpment watershed, the creek serves a critical role in the recreational green belt which divides Hamilton and Stoney Creek. The source of this creek must be celebrated, not fenced off from public access due to landfill hazards. This proposal investigates beyond material recovery, into the possibilities of resource, ecosystem, and community recovery. Landfill mining, material sorting, and power generation through incineration are employed to reduce landfill volume. As the landfill is consumed, a new landscape is constructed, providing improved flood-prevention at the creek and a sanitary lined landfill for those materials remaining on site. Creek, forest, and field habitats are restored on site without the threat of contamination from landfill contents. The public can safely view the landfill mining operations from an elevated walkway, having new experiences with every visit. As the boundaries of the closed landfill are stripped away, the source of the Red Hill Creek and the new recreational parkland are made publicly accessible. Using this design as a reference, the equipment and operations designed for this site can be developed into a province-wide proposal.

The Ottawa Hospital cancels hundreds of elective surgeries every year due to a lack of beds, and has an average weekday occupancy rate above 100%. Our approach to addressing these issues, by way of informing administrators of resource needs, was to model the flow of patients coming and going from the hospital. We used administrative data from the Ottawa Hospital to build a time-series model of emergency department admissions, and studied models that would predict next-day discharge of patients currently taking up hospital beds. In the latter, we considered population-averaged models for groups of patients based on their primary medical condition, as well as subject-specific models. We included the random effects from subject-specific variation to improve on predictive accuracy over the population- averaged approach. The result was a model that provided more realistic probabilities of discharge, and stable predictive accuracy over patient length of stay.

Clinical decision rules improve health care fidelity, benefit patients, physicians and healthcare systems, without reducing patient safety or satisfaction, while promoting cost-effective practice standards. It is critical to appropriately and consistently apply clinical decision rules to realize these benefits. The objective of this thesis was to understand how physicians use the Ottawa Ankle Rules to guide radiography decision-making. The study employed a clinical judgment survey targeting members of the Canadian Association of Emergency Physicians. Statistical analyses were informed by the Brunswik Lens Model and Social Judgment Analysis. Physicians’ overall agreement with the ankle rule was high, but can be improved. Physicians placed greatest value on rule-based cues, while considering non-rule-based cues as moderately important. There is room to improve physician agreement with the ankle rule and use of rule-based cues through knowledge translation interventions. Further development of this Lens Modeling technique could lend itself to a valuable cognitive behavioral intervention.
