2020-Current year OA Pubs

SIGNIFICANCE: Stroke is the leading cause of chronic disability in the United States. How stroke size affects post-stroke repair and recovery is poorly understood.

AIM: We aim to investigate the effects of stroke size on early repair patterns and determine how early changes in neuronal circuits and networks predict functional outcomes after stroke.

APPROACH: We used wide-field optical imaging, photothrombosis, and the cylinder-rearing assay to examine changes in neuronal circuit and network activity in the context of functional recovery after stroke.

RESULTS: Larger strokes ablating

CONCLUSIONS: These results suggest that diffuse patterns of remapping, and desynchronization and hyperconnectivity of cortical …

Nutcracker Syndrome (A Delphi Consensus), Floor Heilijgers, Suresh Vedantham, Et Al.

2020-Current year OA Pubs

BACKGROUND: Nutcracker syndrome (NCS) describes the symptomatic compression of the left renal vein between the aorta and superior mesenteric artery. Whereas asymptomatic compression is a common radiological finding, patients with NCS can report a range of symptoms. There are no specific diagnostic criteria and interventions include a range of open surgical and endovascular procedures. Therefore, we wished to develop an international consensus document covering aspects of diagnosis, management, and follow-up for patients with NCS.

METHODS: A three-stage modified Delphi consensus was performed. A steering committee developed 37 statements covering 3 categories for patients with NCS: diagnosis, management, and follow-up. These …

Ecological Grief: How Can We Bear This Together?, Susan Bailey, Nicholas Gerrish

Research outputs 2022 to 2026

The impacts of human activity on ecosystems are increasingly evident through ecological degradation and climate change. Despite this, in many jurisdictions across the world, action to address and curtail destructive human activities is slow and resisted at all levels. In this article, we suggest that this resistance is connected to deep ecological grief. We introduce a dual approach to understanding ecological grief, using concepts of unprecedented and unacknowledged grief. Unprecedented grief is felt in response to the loss of our ecosystems and unacknowledged grief connected to the anticipated loss of lifestyle necessary to curtail destructive human behaviour. Drawing upon an …

Affective Forecasting With A Chance Of Collective Action: Women’S Anticipated Affect After Acting Against Sexism And Its Relationship To Collective Action Intentions, Adrianna Tassone

Theses and Dissertations (Comprehensive)

Confronting sexism elicits social costs like name-calling (Mendes et al., 2018) and anticipating these costs inhibits confrontation (Good et al., 2012). But taking collective action can also improve women’s wellbeing and reduce negative emotion (Foster, 2015). How women anticipate their own emotions in response to social cost may be a predictor of action. However, it is not yet known how women anticipate taking action will make them feel, and how perceived costs relate to these predictions and action intentions. The present thesis integrates two previously distinct literatures, affective forecasting (Gilbert et al., 1998) and collective action motivation to assess the …

Coupling Remote Sensing And Modelling To Monitor The Spatial Distribution And Trends Of Surface Temperature And Ice Thickness On Sub-Arctic Lakes, Gifty Attiah

Theses and Dissertations (Comprehensive)

Lake surface temperature (LST), lake ice thickness (LIT), and lake ice phenology (LIP) play significant roles in the diverse regional processes of freshwater in cold regions. They offer direct indications of regional weather and climate conditions, and their interactions with the atmosphere impact climate processes. Furthermore, lake ice is valuable to northern communities, such as those in the Northwest Territories (NWT). Ice roads, including the longest ice road in the NWT, spanning over 80 lakes, are constructed during winter to haul goods to and from industrial establishments (e.g., mines) and for travel within and between communities. A significant challenge to …

The Impacts Of Permafrost Thaw Slumps On Arctic Stream Ecology, Maria Dolan

Theses and Dissertations (Comprehensive)

Climate change is intensifying permafrost thaw across terrain of the circumpolar Arctic. Increased temperatures and rainfall at northern latitudes have resulted in the expansion of thermokarst features such as retrogressive thaw slumps, which make previously frozen debris available for transport into nearby river systems. In the Peel Plateau, Northwest Territories, the mobilization of these materials exposes rivers to a large quantity of sediment and solutes that may act as a chronic, press disturbance, potentially altering stream food webs. Here, I examine if: 1) thaw slumps have driven changes to the physical and biological properties of slump impacted streams since an …

Children's Interpretation Of Others' Faces Covered With Medical Masks, Sevval Cinar

Theses and Dissertations (Comprehensive)

How we recognize and regulate emotions is fundamental to overall health and wellbeing. Emotional recognition and understanding are key to proper communication and emotion regulation. Barriers, such as masks, might have an impact on the way children recognize and interpret others' emotions, and therefore the way they learn, communicate, and regulate their own. The COVID-19 pandemic necessitated widespread mask-wearing, raising questions about its impact on children’s emotional development. Using a sample of children with varying levels of exposure to mask wearing adults (N= 13, ages 4 to 6), we investigated how prolonged mask wearing predicts emotion recognition, particularly …

Capital Structure Models And Contingent Convertible Securities, Di Meng

Theses and Dissertations (Comprehensive)

The 2007-09 financial crisis showed financial institutions are vulnerable during distressed times. As an alternative resolution to a government bail-out, contingent convertible securities (contingent capital or CoCos) were proposed by various researchers. CoCo is a hybrid capital security that converts from a bond to common equity when a pre-determined event occurs. The loss absorption mechanism of CoCo is essential to the financial health of a bank during a crisis as it provides an instant capital infusion when public capital is difficult to access.

In this thesis, we first implement a methodology to calibrate capital structure models for large Canadian banks. …
