2023 — Examining the impact of gender-based microagressions and institutional betrayal on women holding multiple marginalized statusesRésumé
Microaggression refers to subtle, often indirect, discriminatory behavior committed against members of marginalized groups. The subtle nature of microaggressions can often make them seem innocuous, however, they can have a determinantal impact on those who experience them. Women are a marginalized group who experience microaggressions on the basis of gender, rooted in sexism. Further, many women hold multiple marginalized statuses based on their race, sexuality, disability, age, religion, body size, or socioeconomic status. As such, they may also experience microaggressions based on these intersectional identities. While microaggressions in themselves have been shown to be negatively related to mental health, it … Lire la suite

2023 — Attentional blink: Restricted attention necessitates conscious perceptionRésumé
In attention capture studies, a target stimulus is poorly identified when presented 200-500 ms after the presentation of a task-relevant distractor, a phenomenon referred to as the attentional blink. Evidence regarding the necessity of consciously perceiving the distractor in yielding an attentional blink is inconsistent in the literature. The goal of this thesis was to clarify under which conditions conscious perception of a distractor is necessary to trigger an attentional blink. It was hypothesized that the presence of a blink would vary according to the predictions of the novel restricted attention hypothesis, such that additional conditions must be met for … Lire la suite

2023 — Algal control and prevention technologies for Lake Diefenbaker irrigation canalsRésumé
The Lake Diefenbaker irrigation project makes up an extensive 500 km of canals that officially began in July 2020. These canals contain pumps for increased and enhanced irrigation throughout southern and central Saskatchewan. However, the efficiency of the canals is hindered by the growth of filamentous algae. The filamentous algae are a nuisance and block pumps, making it difficult for water to be distributed to all the desired locations within the province. Currently, a synthetic chemical, Magnacide H, is utilized to control the growth of the algae at the cost of approximately $1 million per year, which is high cost. … Lire la suite
