Current measurements in the Drake Passage
(1972) Foster, Leslie Alexander; Not Applicable; Master of Science; Department of Oceanography; Not Applicable; unknown; Not Applicable; Dr. D. J. Lawrence; R.R. Lively; C.R. Mann
As part of the Hudson 'TO Expedition, an array of 12 current meters was moored in the Drake Passage near longitude 68° W for 10 days in February, 1970. A hydrographic section was run across the passage at the beginning and end of the mooring period. The geostrophic currents using assumed levels of no motion gave results similar to past studies. The current meter records indicated that a minimum velocity is found in the middle of the water column and they also showed the presence of a semi-diurnal tidal component. The best compromise between the current meter data and the hydrographic data is a variable level of no motion with a net transport qf 5 sverdrups toward the west, but because of lack of current meter data at the convergence zone, an unambiguous transport figure could not be determined.

Suburban infill : an intervention for Gaborone's pedestrianways
(2008) Othogile, Helen Goabaone; Not Applicable; Master of Architecture; School of Architecture; Not Applicable; Jacques Rousseau; Not Applicable; Peter Sassenroth; Niall Savage
The thesis explores the potential benefits and possibilities of infill interventions within Gaborone's existing pedestrianways. The city was designed and laid out by European planners during the time of the Protectorate at the height of the Garden City movement, to become the new administrative capital for the newly independent Botswana. The resultant pedestrianways are an imported urban model that literally got "lost in translation" and as a result, the pedestrianways remain highly underutilized and could rightly be considered as wasted spaces in the city. Through a historical understanding and critical analysis, the thesis identifies why the pedestrianways are not working; how people are using them; and how the city could begin to redevelop them into meaningful and sustainable spaces.

Scales of Change: What lived experiences of deindustrialization in Cape Breton can teach us about "just" energy transitions
(2026) Leviten-Reid, Adlie
As Canada’s energy systems move away from fossil fuels toward renewable energy source, anchor industries are closing in some places and emerging in others. These dynamics are reshaping the economies and social fabrics of communities built around industry towns. As this process unfolds, policy makers and scholars contemplate approaches to a “just transition” so that no one is left behind through these periods of sociotechnical change. Despite consensus among governments and civil society that these periods of transition should unfold in a way that is “just”, approaches diverge. Some emphasize concentrated economic supports and job creation while others call for broader economic and political restructuring away from extractive development models that externalize social and place-based costs. Historical cases of deindustrialization provide a window into the stakes involved in these different transition approaches. With this relationship between deindustrialization and “just transition” in view, we draw on eight oral history style interviews documenting community responses to deindustrialization in Cape Breton from 1967 to the present day. Participants detailed embodied impacts of the closures of central industries (coal extraction and steelmaking), affecting sense of place, health, family structures, and identity. When describing self-organizing to support their own needs during periods of transition, participants also recalled the failure of government employment-oriented initiatives to prioritize community members’ overall well-being, all while blaming them for their circumstances. These findings highlight the limits of treating transition as a technical labour-market problem - approaching transition in this way does not capture the lived realities of deindustrialization. On this basis, approaches that pursue broader transformations that internalize the social and place-based costs of sociotechnical change are more likely to address the full range of impacts experienced by communities facing the loss or significant downsizing of major industries.

Leading Us Forward: Leadership Development Programs and the Leaders of the Future
(2026-04-20) Eve Dewing
Leadership development programs have exploded in popularity across Canadian Post-Secondary Institutions. These programs are free, offer no degree or formal accreditation, and yet universities and funders are pouring hundreds of thousands of dollars into them. This paper seeks to address what these programs teach and why. Using Semi-structured interviews with creators and facilitators of post-secondary leadership development programs, this research works to understand how they view the programs and how post-secondary institutions view these programs. Risk society theory is applied to the data to make sense of why change is the most prominent intended outcome, how self-actualization is used, and why post-secondary institutions want to address global complexity.

CHARACTERIZING BENTHIC AND PLANKTONIC CYANOBACTERIA DYNAMICS IN KEJIMKUJIK NATIONAL PARK
(2026-05-20) Macdonald, Sarah; Not Applicable; Master of Applied Science; Department of Civil and Resource Engineering; Not Applicable; n/a; Not Applicable; Dr. Daniel G. Beach; Dr. Janice Lawrence; Dr. Lauren Somers; Dr. Rob Jamieson
Kejimkujik National Park and National Historic Site contains over 46 pristine lakes and several interconnected rivers and streams, providing habitat for wildlife and recreational activities. Cyanobacteria are an increasing concern in Atlantic Canada due to their association with numerous canine mortalities. This study is the first to exclusively investigate cyanobacteria dynamics within the park. Planktonic cyanobacteria communities were assessed in 18 lakes and did not dominate microbial communities, although their occurrence followed distinct environmental thresholds. Cyanobacteria were more commonly detected in lakes with total phosphorus <12 μg/L, total organic carbon <10 mg/L, and pH levels > 5.5. Benthic cyanobacteria communities were assessed in two brooks and one lake and were a dominant component of the biofilm. Low-level anatoxins (<120 ng/g) and microcystins (<220 ng/g) were detected in biofilm samples. These findings improve our understanding of cyanobacteria communities as well as their toxin production in minimally impacted systems in Atlantic Canada.

DEVELOPMENT AND EVALUATION OF SULFORAPHANE-RICH BROCCOLI OINTMENT FOR ATOPIC DERMATITIS MANAGEMENT IN BALB/C MICE
(2026-05-14) Chaturvedi, Chandrika; No; Master of Science; Department of Plant, Food and Environmental Sciences; Received; n/a; No; Dr. Yunfei Jiang; Dr. Carman A. Giacomantonio; Dr. H.P. Vasantha Rupasinghe
This study investigated broccoli (Brassica oleracea) as a sustainable source of bioactive phytochemicals and its potential application in atopic dermatitis (AD). Ultrasound-assisted ethanol extraction (25% ethanol, 41°C, 32 min) yielded optimal total glucosinolate content (36.6 mg sinigrin equivalence/g DW) and sulforaphane content (0.38 mg/g DW), demonstrating strong antioxidant and anti-elastase activity. In the 2,4-dinitrochlorobenzene (DNCB)-induced BALB/c mouse model, AD-like symptoms were successfully established, confirmed by elevated serum IgE and dermatitis scores. Topical application of 15% broccoli head (BH) and broccoli sprout (BS) extracts significantly reduced dermatitis scores, epidermal thickness, and serum IgE levels. The 15% BS ointment further decreased serum CCL11 levels, consistent with its approximately 17.5-fold higher sulforaphane content. Serum cytokines showed no significant changes, indicating that therapeutic effects were primarily localized within the skin. These findings support broccoli-derived extract ointments as promising natural topical agents for AD management and functional cosmeceutical development.
