Over the past decade, dozens of acidic (pH ~3) seepages have emerged in these headwaters, causing vegetation dieback and mobilizing metals at acutely toxic concentrations in receiving streams. Acid generated during sulfide-mineral oxidation also accelerates CO2 emissions by driving carbonate-mineral dissolution. Major downstream sub(Arctic) rivers show significant multi-decadal sulfate concentration increases, yet their metals concentrations remain stable because of attenuation and dilution processes. Headwater stream acidification signals a major perturbation in metal, carbon, and sulfur cycling linked to permafrost thaw with far-reaching consequences for water resources, northern communities, ecosystem health, and Earth’s biogeochemical future.Item type: Item , Access status: Open Access , Mapping AI value alignment practices: an evidence- based approach for safer public service AI(Carleton University. School of Public Policy and Administration, 2026-05-14) Ojo, Adegboyega; Ferraiuolo, Nicolas; Polanska, KasiaThe rapid adoption of artificial intelligence (AI) systems in public sector organizations raises a question that traditional governance frameworks were not designed to answer: how can governments ensure that AI systems operate in ways consistent with public values? Value alignment, the practice of ensuring that AI behaviour and decisions reflect human intentions and societal values, has emerged as a foundational requirement for trustworthy AI. Yet despite growing attention to AI ethics, understanding what and how public sector values should be reflected in AI alignment practices, and on what methods support their operationalization, remains limited. This report addresses that gap through two systematic literature reviews. The first reviewed 41 empirical and conceptual studies on AI value alignment in public sector contexts, using Canada's Values and Ethics Code for the Public Sector as an analytical lens to assess the extent to which traditional public sector value frameworks are considered in AI governance. The second drew on adjacent fields, including decision sciences, participatory design, and deliberative democracy, to identify methods for value elicitation and aggregation that public sector organizations can apply. The findings indicate that the Code's five values: respect for democracy, respect for people, integrity, stewardship, and excellence, are broadly reflected in documented AI alignment practices, supporting the Code's role as a legitimate starting point for Canadian public sector AI governance. At the same time, the literature reveals significant gaps in how value alignment is currently understood and practised. Sustainability and culturally pluralistic values are underrepresented across the corpus; few studies offer concrete methods for translating high-level values into design and procedural requirements, and institutional supports such as enforcement mechanisms, dedicated oversight roles, and workforce capacity remain underdeveloped. Existing governmental value frameworks can be useful but are insufficient on their own to guide AI value alignment in the public sector. To address these gaps, the report introduces a four-stage approach to value alignment: application scope clarification, value mapping, value elicitation and deliberation, and value integration and documentation. The methods review further demonstrates that no single value elicitation technique is universally appropriate; method selection must be matched to the application's stage, stakeholders, scale, output requirements, capacity, and equity considerations. The paper concludes with recommendations to strengthen public sector AI value alignment in Canada including: 1) adopting a structured value alignment process; 2) anchoring deliberation in the Code while supplementing it with values such as privacy, autonomy, explainability, and sustainability; 3) embedding value alignment in existing governance instruments such as the Algorithmic Impact Assessment; 4) building deliberative and facilitation capacity across the public service; and 5) sustaining alignment over the AI lifecycle through monitoring and re-engagement.Item type: Item , Access status: Open Access , An Oral History with Errol and Delphine Francis(2015-04-17)Errol and Delphine Francis were both born and raised in Uganda and held fond memories of life in East Africa. They reflected on a very comfortable life, with warm weather and a great balance between work and family life. Errol completed his high school and pre-university courses in Uganda and began a career in the travel industry there. Delphine completed her teaching certificate abroad, and returned to Uganda to become a teacher trainer at the Shimoni Teacher Training College. Delphine was 7 months pregnant when the expulsion decree was announced. Since both Errol and Delphine held Ugandan citizenship, they were admitted for resettlement in Canada. They both flew into the Longue Pointe military base in Montreal and were then relocated to the YMCA, also in Montreal. Delphine quickly landed a job within just a few days as a tailor in a shop close by. They both recalled an overwhelming amount of support in Montreal from immigration officials and Canadians, as they received winter clothing and other items for their newborn. Within a few months the couple moved to Toronto, in August of 1973, as Errol had secured employment in the travel industry. Delphine took up a position as a teacher in the Catholic School Board. Over the years, the couple raised their children in Canada and progressed in their respective careers. They are happily retired and pass their time travelling and spending time with family and friends. This oral history was conducted in Errol and Delphine’s home in Toronto, Ontario.
