Purpose: The COVID-19 pandemic led to major service disruptions in the healthcare sector, especially regarding sexual and reproductive health services. However, the impact of the pandemic on Canadian adolescents is relatively unknown. This study aimed to investigate the impacts of the COVID-19 pandemic and associated public health measures on the sexual and reproductive health (SRH) of adolescents in Alberta, Canada. Methods: A qualitative study using an interpretive description (ID) approach and community-based participatory research principles was conducted to capture the subjective experience and perceptions of adolescents and service providers. With the collaboration of the Adolescent Advisory Group and community partners, 18 adolescents and 15 service providers were recruited for the study through purposive sampling. Findings from the qualitative interviews were analyzed using thematic analysis. Results: Three major themes emerged from the analysis: (1) COVID-19 SRH experience, (2) barriers to SRH, and (3) adolescent SRH strategies. Our findings highlight numerous barriers and challenges that prevented adolescents from accessing SRH education, products, and services. Conclusion: The COVID-19 pandemic had a profound impact on the SRH and the well-being of adolescents. Our study reflects the need for diverse SRH strategies to maintain continued access to SRH resources during disruptive events, such as the pandemic. Plain language summary: Access to sexual and reproductive health (SRH) services is a basic human right. All individuals require access to appropriate SRH services to maintain their optimal sexual and reproductive health. Adolescents require special guidance, support, and youth-friendly services in matters of SRH as they enter puberty and explore their sexual identity. However, during the COVID-19 pandemic, many health and SRH services were suspended. Access to SRH products and services became difficult due to public health restrictions, which has possible negative consequences for adolescents' SRH. The experiences of adolescents during the COVID-19 pandemic regarding their SRH are not reported in Alberta, Canada. Therefore, we explored the impacts of these public health restrictions on adolescents' SRH. We performed qualitative interviews with adolescents and SRH service providers to know their perspectives on how the pandemic influenced the SRH of adolescents. This paper provides insights into the barriers faced by adolescents while accessing SRH services during the pandemic, as well as their perceptions of digital strategies, such as mobile applications, and other recommendations for supporting SRH education and services. Based on the study findings, an adolescent-friendly mobile application will be developed to provide a virtual platform connecting adolescents to SRH educational resources, services, and support.

The results and interpretations of published Canadian field studies on the reproductive status of fish in waters receiving pulp and paper mill effluent discharges were reviewed. Most of the information was obtained from indicator measurements such as gonad size, fecundity, and serum steroid levels in wild fish sampled at reference and effluent-exposed sites. Difficulties in selecting appropriate sampling sites, natural variability, and the ecological relevance of the indicator measurements were identified as major complicating factors for the interpretation of the field data. Consequently, it was not possible to conclude to what extent, if any, widespread effects on fish reproduction are being caused by pulp and paper mill effluents or that specific manufacturing processes are causing such effects. Further research on the normal variability and predictive capability of reproductive indicators, for example, using an integrated approach (i.e., laboratory testing, mesocosm studies, and field work), is recommended.

In this paper, we explore how the power wielded by regional incumbents has impacted subnational innovation agendas. Our findings suggest that the design of mission-oriented innovation policies should be more attentive to regional innovation policies and their relationship to how innovation may serve to bolster incumbents and not undermine them. We use a case-study of innovation in fossil fuels. Recently, innovation policy literature has explored innovation policy and global climate as a major topic. On the one hand, carbon lock-in has been used to explain why there has been such difficulty in reducing carbon emissions, in many cases, despite an increasing emphasis of mission-innovation policies. On the other hand, mission-innovation policies are believed to be a key to the development of disruptive innovations that could break this carbon intensive path dependency. Although the two literatures explore the same problem, there could be more integration. While carbon lock-in is being considered in the mission-innovation literature, it nevertheless has been largely overlooked at the mission-setting stage. On the other hand, the lock-in literature has tended to overlook the findings of mission-oriented innovation literature in offering solutions, which suggests that there is a more productive role for mission-oriented innovations in breaking free of previous constraints to serve in the low-carbon energy transition. To make our case, we argue it is important to distinguish among the various impacts disruptive innovations have on the market shares of incumbents'. We propose the following three schema: new market, market rewarding and market destroying. By variegating the potential impact of innovations, we suggest that mission-oriented innovation polices may be designed to only support certain types of innovations that do not directly undermine the market share of incumbents. Using a detailed case study of the Province of Alberta, Canada, we then explore the role of the province's mission-oriented policy in the development of technology to produce the Canadian oil sands. The case study illustrates how incumbents influenced the establishment and direction of the mission's goal. Shifts in incumbency opposition toward the province's mission-oriented innovation policy coincided with the changing impact of the innovation from being market destroying to market rewarding. We suggest that future research should be more attentive to the role of incumbents in influencing mission-oriented innovation policy and the importance of their influence at the mission-setting stage. Furthermore, we suggest that to meet the grand challenge of addressing climate change through mission-oriented innovation policies, these policies must be designed to break free of these institutional constraints.

The implementation of school reforms to advance reconciliation with Indigenous peoples provides an opportunity to explore what Canadians think is important in framing their identities and values. This paper draws on data from a survey of public perspectives on education for reconciliation activities in two Canadian provinces, Alberta and Saskatchewan. We consider the broader community context within which schools are located. By examining public perspectives, we are able to assess how curricular initiatives related to reconciliation are understood by community members, both as a priority in itself and in relation to other key curricular areas. Informed by critical race theory, our findings suggest that reconciliation is restricted to activities that do not involve extensive change to existing curricular and ideational frameworks. These perspectives exist alongside extensive opposition to reconciliation justified by claims that Indigenous experiences and perspectives are receiving undue attention relative to more pressing educational priorities. Our findings suggest that aims to transform dominant understandings about Canadian history and identity remain far from being fulfilled. [ABSTRACT FROM AUTHOR]

This paper provides insights into the little‐explored gendered perspective of the parenting practices of Somali immigrant mothers in a Canadian province (Alberta). We use a critical ethnographic methodology and a transnational feminist framework. Semi‐structured interviews were conducted with ten Somali mothers aged 18 to 50. Mothers were interviewed about their parenting practices in a post‐migration context, including challenges. Our results show immigrant mothers combine their cultural values with new values from Canada that they find effective. We find gendered differences in how parenting experiences are perceived. Our results suggest the need for anti‐racist and culturally safe health, education, and child policies and practices. [ABSTRACT FROM AUTHOR]

Purpose: Anterior cruciate ligament (ACL) injuries are one of the most frequently studied injuries in orthopedic care and research. However, limited epidemiological data are available in Canada regarding trend and distribution of anterior cruciate ligament reconstruction (ACLR). In this paper, our purpose was to assess trends of ACLR between 2002/03 and 2018/19 by age, sex, season of surgery, and location (inpatient vs outpatient) of surgery. Methods: In this descriptive epidemiological study of retrospective data available from Alberta Ministry of Health, we report annual incidence of ACLR between 2002/03 until 2018/19 among Albertans aged 10 years and older. Information was collected by authors from physician claims database for primary ACLR and revision ACLR and linked with other databases. Incidence proportions (number of ACLR/100,000 population) were calculated and compared by age category and gender over the study period. Results: A total of 28,401 primary ACLR and 2085 revision ACLR were identified during the study period. Age-standardized annual incidence of primary ACLR increased from 40.6 to 51.2 per 100,000 population aged 10 years and older. Average annual increase in ACLR incidence was higher among females (1.8% per years) compared to males (0.96% per year). The overall peak incidence and peak incidence among males was observed in 20–29 year age group, whereas peak incidence in females was observed in 10–19 years of age. The number of ACLR in females outnumbers those among males for 10–19 year age group. Generally, a lower proportion of ACLR were conducted in summer compared to other seasons. Primary ACLR conducted in outpatient setting increased from 72% in 2002/03 to 97% in 2018/19. Conclusion: The incidence of ACLR is increasing in Alberta, especially among females and among younger cohorts under 20 years of age. This information can help clinicians to provide patient education and policy-makers to design and implement targeted ACL injury prevention programs. Level of evidence: Level III.

The growing aging population in Canada has multi-faceted psycho-social needs. Social workers are well-positioned to address these needs, despite many challenges. This paper reports findings from the World Café at the Gerontology Symposium in Alberta, Canada, held in 2018. The goal was to learn from social work practitioners, researchers, and educators (N = 49) about current and future needs of gerontological social work in Alberta. There were two research questions: 1) What strategies do social workers need on the micro, mezzo, and macro levels to help better serve the growing older adult population in Alberta? (R1) 2) How can social workers promote the value and contribution of gerontological social work within the interprofessional community? (R2) The data were analyzed using qualitative content analysis. Ten R1-related themes emerged: personal traits of a social worker; professional skills; bio-psycho-social needs of older adults; community connections; access to benefits; gerontological social work education; integrated healthcare; aging policy; ageism; and advocacy to strengthen the voice of older adults. The three R2-related themes include strengthening the status of the social work profession; building trust through demonstrated skills; and interprofessional education and practice.

Sport and education organizations have established models to ensure that coaches and teachers understand the physical, social, emotional and mental development of children. Such pathways of intentionally designed models fail to exist in the recreation sector where many physical activity (PA) programs are mainly developed based on convenience and instructor availability rather than on established credentials and current pedagogy practices. Addressing this gap, this paper explores the creation of an intentionally designed model of programming for children's structured recreation, which is defined as sport or PA-based programs that are planned and led by an instructor. This proposed model is contextualized within the province of Alberta, but may be applicable across the nation. The authors further define "intentionally designed" as the development of purposeful programming with specific objectives that align with outside sources. One such source comes from the Canadian Parks and Recreation Association, who has created a Canadian Recreation Framework, an initiative to ultimately develop the well-being of all Canadians. The proposed, structured recreation model also incorporates several guiding principles including physical literacy and sport philosophy. Physical Literacy (PL) focuses on the lived body as the embodied dimension of our human experience, and how it can be enriched through various experiences that enable us to reach our full potential (Whitehead, 2007). It is about viewing the body holistically rather than separate from the entire being. By planning diverse PA in four environments, including land, water, air, and ice, the model also aligns with the sports sector and its philosophy of developing both fundamental movement skills and fundamental sport skills. Moreover, with allocated playing time, intentionally designed structured lesson plans, and one consistent leader in each activity, the model aims to increase the participants' motor proficiency and levels of PA while building their confidence and competence across distinct exercises.

Walleye (Sander vitreus) populations in Alberta, Canada, collapsed by the mid-1990s and were a case study in the paper Canada's Recreational Fisheries: The Invisible Collapse? Here we fit age-structured population dynamics models to data from a landscape-scale monitoring program to assess walleye population status and reconstruct recruitment dynamics following the invisible collapse. Assessments indicated that populations featured low Fmsy values of approximately 0.2–0.3 under conservative assumptions for the stock–recruitment relationship but that many populations were lightly exploited during 2000–2018. Recruitment reconstructions showed that recovery from collapse in 33/55 lakes was driven in part by large positive recruitment anomalies that occurred during 1998–2002. Additionally, 15/55 lakes demonstrated cyclic recruitment dynamics. The documented recruitment anomalies and cyclic fluctuations could be due to environmental effect(s) or cannibalism, and experimentation is likely necessary to resolve this uncertainty. These findings contribute new information on the recovery dynamics of walleye following the invisible collapse and demonstrate the effectiveness of coupling traditional fisheries science models with broad-scale monitoring data to improve understanding of population dynamics and sustainability across landscapes.

In 2016, Canada was ordered to implement Jordan's Principle by the Canadian Human Rights Tribunal. In response to the order, Canada created the Child First Initiative to provide federal funding for provincial and territorial organizations supporting First Nations children's health, education, and social service needs, including service coordination. In the shifting national landscape of Child First Initiative funding, there is a lack of evidence on how pediatric healthcare services are addressing the serious health and healthcare inequities experienced by many First Nations children. This paper describes the implementation of a Child First Initiative by the First Nations Health Consortium in the Alberta region and research findings that provide insights into the complexity and challenges of advancing First Nations children's health and health equity within the current federal Child First Initiative mandate in this province. This paper highlights the need for transformative pediatric healthcare approaches that expand beyond an individual and demand-driven system and orient towards practices and policies that are sociallyresponsive. Also, this paper highlights that First Nations leaders and Jordan's Principle initiatives play a leading role in the design and delivery of all pediatric healthcare services with First Nations communities, families, and children across Canada.

Background: Collecting and monitoring the information from patients through patient-reported experience measures (PREMs) about the quality of care they receive is important for tracking changes in healthcare quality, stimulate innovation, and enhance person-centred care. The objective of this theoretical paper is to discuss the use of implementation science theories, models, and frameworks to inform and evaluate the integration of the electronic collection of PREMs (ePREMs) in healthcare quality improvement for primary care in Canada. Methods: To assess potential knowledge-to-practice gaps in implementing ePREMs in primary care in Alberta, the overarching implementation model that will be used is the Knowledge to Action Cycle. An integrated knowledge translation approach will ensure ongoing engagement of key stakeholders (e.g. primary care providers, patients) throughout the study. ePREM implementation will be informed by the identification of barriers and facilitators to implementation using the Consolidated Framework for Implementation Research (CFIR). The CFIR brings an organizational perspective providing an opportunity to explore the intervention characteristics, the context of implementation, individual factors, and the processes that influence implementation of ePREMs in healthcare. Identified barriers and facilitators to ePREM implementation will be mapped to evidence-based implementation strategies and prioritized by stakeholders. The RE-AIM framework will be used to guide the evaluation of ePREM implementation outcomes after six months of implementation by assessing Reach, Effectiveness, Adoption, Implementation, and Maintenance (sustainability). Discussion: Consultations with stakeholders affirm the importance of using integrated knowledge translation approaches and the need to better understand how to integrate ePREMs in primary care. Using an implementations science approach, this study can provide guidance for mitigating important ePREM implementation challenges and promote the successful uptake and use of ePREMs for quality improvement in healthcare.

Wheat is affected by many fungal diseases that can cause severe yield and quality losses. Disease prediction models generally employ weather data to estimate potential for infection to determine timing for fungicide applications, but these models fail to account for the presence and quantity of pathogen inoculum. This study adapted highly specific qPCR primers to identify and quantify, in real-time, inoculum present in air for the six most important wheat pathogens in Canada. Fungal spores were collected using either Burkard spore collectors and quantified using qPCR or microscope slides covered with adhesive tape and identified and quantified using microscopy. Samples were collected from seven different sites in southern Alberta throughout the 2015–2017 growing seasons. The results demonstrated that qPCR can reliably identify and quantify spores from Puccinia striiformis f. sp. tritici, P. triticina, P. graminis f. sp. tritici, Blumeria graminis f. sp. tritici, Pyrenophora tritici-repentis, and Fusarium graminearum. The limits of detection of DNA for primer pairs in singleplex tests ranged from 0.0001 ng for P. graminis to 0.001 ng for P. tritici-repentis, which corresponded to approximately 3 spores for P. tritici-repentis and F. graminearum and 1 spore for the other pathogens. Conversely, microscopy permitted identification of rusts to the genus but not to the species level and was ineffective in quantification of the remainder of the wheat pathogens. This study will contribute to the development of a fast and reliable forecasting system that will enable identification and quantification of airborne pathogens in real-time before initial disease symptoms appear.

This paper contributes to research on and theories of the state's role in Canadian sport development by examining factors that led the Alberta government to create the Alberta Sport Council, Canada's only Crown corporation with a sport mandate. The data used were collected from interviews and numerous documentary sources. The corporatism and the attribution of public status to private interest groups. Accordingly, the study identified key individuals, organizational factors, and the unique political and economic characteristics of Alberta that influenced the council's creation. The paper concludes that despite this or organization's uniqueness, it reflects the same contradictory form of sport intervention found in other Canadian governments. [ABSTRACT FROM AUTHOR]

Improving access to domestic and international markets can create large economic benefits. Multimodal infrastructure corridors of road, rail, utilities and communications can improve accessibility by reducing interprovincial and international trade costs. Depending on the geographical area they serve and the modes of transport and types of connections they promote, infrastructure corridors can create trade-offs and synergies between different kinds of economic, social, and environmental outcomes. Yet the implied effects can vary across different regions, population segments and industries. A complete review of a proposed infrastructure corridor package involves a rigorous analysis of all of these potential effects. In this paper, we focus more specifically on quantifying potential gains from reductions in trade costs on Alberta's economy and identify the importance of improved access to lower cost transportation options like rail for select commodities. We find that lowering trade costs substantially increases Alberta's real GDP through its effect on international and interprovincial trade flows. Although interprovincial tariffs on domestic goods are forbidden by the Canadian Constitution, the economic effect of internal non-tariff trade barriers is substantial. Albrecht and Tombe (2016) show that eliminating these interprovincial trade costs would increase Canada's GDP between three to seven per cent. These barriers represent additional costs on Canadian firms and adversely affect their competitiveness in domestic and international markets. High interprovincial trade costs may also pose an additional barrier to entry for foreign firms otherwise willing to enter the Canadian market. As a result of this, Canadian firms end up producing at a less efficient scale and pass the cost of these inefficiencies to consumers. Interprovincial trade costs therefore hurt both producers and consumers. Gains from improved infrastructure are also amplified by the interconnected nature of industries. Output of one industry is often an input for another industry. Shipments cross provincial and national borders as part of these supply-chain relationships which allow for more efficient production but at the same time create additional trade costs on producers. Infrastructure corridors provide one option to lower these trade costs by increasing transportation capacity, creating savings in travel time and distance, creating better quality physical transport infrastructure, simplifying the regulatory and legislative differences across provinces and territories, and improving access to information, to name a few. To quantify the potential effect of increased transportation infrastructure on trade costs, we combine rich data on interprovincial trade flows and shipment-level information on volumes, values, and transportation costs by mode. We empirically estimate the potential for increased rail shipment capacity on shipment costs between various internal trade pairs within Canada. Two key results stand out. First, we find that while distance is an important factor, a higher share of shipments by rail is associated with markedly lower trade costs. Specifically, we find a 10 percentage point increase in the share of value shipped by rail is associated with a 3.2 per cent lower aggregate cost of trade after controlling for commodity, source, and destination of shipments. Second, we also find important differences in the relevance of rail across commodities. We find larger trade costs reductions for coal, mineral products, and fuel oils. The focus on rail is an important one for Alberta since coastal or canal shipping is not a feasible alternative. As a natural next step, we then evaluate the potential gains to Alberta's economy from increased access to internal and international markets that improved infrastructure might provide. We find that lowering trade costs substantially increases Alberta's real GDP through its effect on international and interprovincial trade flows, in both the short run and the long run. The results show that, in the short run, lower trade costs by one per cent increases real GDP by roughly 0.8 per cent and lower trade costs by five per cent increases real GDP by roughly 4.4 per cent. These correspond to approximately $3 billion to $15 billion per year in additional economic activity in Alberta. We find larger gains in the long-run, equivalent to roughly a one per cent increase in real GDP for each one per cent reduction in trade costs. Gains from lower trade costs come primarily through lower cost access to imported inputs and final goods. There are also gains from increased demand by purchases outside Alberta on goods produced by Albertans. This increases real incomes and productivity, which is captured by the increase in real GDP. The combined results of lower import costs and an increase in GDP imply an about six per cent long-run increase in real personal income, equal to an extra $6,423 annually for the median Alberta family. This is a level effect and represents a persistent increase, not a one-time bump. That is, GDP is permanently higher and by extension, annual personal incomes are also permanently higher. Although we don't explore the infrastructure investment options for lowering the trade costs by these levels, the corresponding impacts on real GDP of doing so indicate how high the costs of expanding infrastructure could be while still yielding net benefits to Alberta. An infrastructure corridor could facilitate the expansion of Canada's rail shipment capacity. While many transportation modes could expand within such a corridor -- including roads, pipelines, transmission lines and so on -- our data allow us to specifically quantify the extent to which Alberta's economy could gain from more access to lower cost shipment options like rail. Rail shipment costs are lower than truck transportation when distances are sufficiently long. We find that each one percentage point increase in the share of non-air trade sent by rail is associated with a 0.32 per cent lower trade cost. This implies that if the share shipped by rail increased by 10 percentage points, then trade costs to and from Alberta would, on average, decline by 3.2 per cent. Expanding the rail capacity is particularly valuable for Alberta, since increasing the share of exports shipped by rail by ten 10 percentage points may increase Alberta's GDP by nearly 1.5 per cent in the short-run and over 2.5 per cent in the long-run -- equivalent to over $9 billion per year in economic activity. This is a relatively large increase in economic productivity -- equivalent to roughly $4,500 per household, on average, per year -- and, in addition, it abstracts from other potential sources of gains, such as increased labour migration into the province. The combined increase in GDP and lower import costs from increased rail penetration imply an increase in real personal income. It is more modest here at approximately 3.3 per cent (rather than six per cent), but still very significant and equal to an extra $3,419 annually for the median Alberta family. As before, it is important to note that this is a level effect and represents a persistent increase and permanently higher annual GDP and annual personal incomes. Our analysis is only a first step and explores only one potential effect of expanding infrastructure capacity. Overall, the potential for positive economic effects from multimodal infrastructure corridors is compelling and warrants additional investigation. Governments can play a role by supporting expanded research activities into the feasibility and potential benefits of dedicated multimodal infrastructure corridors in Canada. In addition, though we made progress using detailed shipment-level data, there are shortcomings in coverage and detail that constrain the scope for potential research. Governments should therefore increase the collection and reporting of relevant data on internal trade to facilitate research into the costs producers and consumers face, and the potential gains from internal trade liberalization. Despite the value of expanding research capacity, our analysis points clearly towards the potential gains from internal trade liberalization. Expanded transportation infrastructure capacity can lower trade costs, and therefore governments hoping to expand internal trade should explore means of increasing such capacity, especially the possibility of increased rail shipment capacity.

Case-crossover designs have been widely applied to epidemiological and medical investigations of associations between short-term exposures and risk of acute adverse health events. Much effort has been made in literature on understanding source of confounding and reducing systematic bias by reference-select strategies. In this paper, we explored the nature of bias in the ambi-directional and time-stratified case-crossover designs via simulation using actual air pollution data from urban Edmonton, Alberta, Canada. We further proposed a calibration approach for eliminating systematic bias in estimates (coefficient estimate, 95% confident interval, and p-value). Bias check for coefficient estimation, size check and power check for significance test were done via simulation experiments to show advantages of the calibrated case-crossover studies over the ones without calibration. An application was done to investigate associations between air pollutants and acute myocardial infarction hospitalizations in urban Edmonton. In conclusion, systematic bias in a case-crossover design is often unavoidable, leading to an obvious bias in the estimated effect and an unreliable p value in the significance test. The proposed calibration technique provides an efficient approach to eliminating systematic bias in a case-crossover study. [ABSTRACT FROM AUTHOR]

The Government of Canada has implemented measures to reduce greenhouse gas emissions, including a carbon tax and its proposed Clean Fuel Standard. Alberta's Oil Sands industry, arguably one of Canada's largest and most energy intensive industries, has made significant progress towards improving energy efficiency and reducing its fossil energy footprint, including investigating options for integrating bio-based feedstocks into bitumen extraction and processing. Nevertheless, developing sustainable bioenergy supply chains remains a crucial challenge to reaching this goal. This paper investigates pathways for harvesting and hauling biomass residues to produce bio-oil that can replace fossil fuels used in oil sands bitumen processing. A 3–stage grid model is developed, comprising a square grid distribution of harvesting fields and district centres. Biomass is collected and hauled to fast pyrolysis units centrally located within square harvesting fields. Raw bio-oil is hauled from fields to the centre of one of 11 District centres, where it is stabilized and blended. Stage–1 and Stage–2 estimate hauling distance using hypothetical roads described by geometric equations and tortuosity factors. Stage–3 hauling of stabilized bio-oil from District centres to upgraders at Scotford AB and Fort McMurray AB is estimated by using web-based mapping tools and actual road networks. Total diesel requirements for hauling are calculated using total distances obtained from the 3–stage hauling model. Average diesel consumption obtained from the model is 0.32 L per 1000 L of bio-oil produced, increasing to 3.45 L per 1000 L bio-oil delivered to district centres. Total diesel consumption is 10.23 and 14.40 L per 1000 L bio-oil delivered to Scotford and Ft. McMurray, respectively. The model shows that co-processing of biomass residues can reduce the fossil energy footprint of processing oil sands synthetic crude oil by 22–28%. The quantity of delivered bio-oil is sufficient to replace petroleum coke and synthetic crude oil used for combustion as well as a substantial fraction of natural gas fuel. Moreover, the model can help to determine the most suitable processing and hauling options at each stage in order to minimize diesel fuel requirements, and the model framework can be extended to other jurisdictions as well as other industries. • 3–stage hauling model for biomass and bio-oil destined for bitumen upgraders. • Diesel requirement estimated using hypothetical and actual road networks. • 87% of bio-oil's energy can replace fossil inputs to synthetic crude production. • Energy footprint is lower by 22% for SAGD operations and 28% for mining operations. • Model is applicable to other jurisdictions and other energy intensive industries.

In this paper, the stratigraphic occurrence of n -alkanes (C n) is investigated in three peat cores (Mildred, JPH4 and McMurray) from the ombrotrophic peatlands in northeastern Alberta, Canada, to determine their origin, biomass input, and paleoclimatic significance. The molecular composition of n -alkanes is dominated by the >C 21 medium- to long-chain homologues, with a strong odd over even predominance. A number of n -alkane-based indices (e.g. predominant n -alkane, C 23 /C 29 , C 23 /(C 27 + C 31), P aq , ACL, and CPI), show changing conditions in the organic matter (OM) input from Sphagnum species or terrestrial vascular plants, which increasingly contributed upwards in the peat profiles, and through time. P aq and C 23 /(C 27 + C 31) proxies are similar in the three cores, and allow us to infer vegetation variations that coincide with the climate alternations of the Medieval Warm Period (MWP), Little Ice Age (LIA), and modern Recent Warming (RW). The utilization of ACL-ket and (C 23 + C 25)/(C 27 + C 29 + C 31)-ket proxies, performed in comparison with n -alkane proxies, further support the biomarker-based reconstructions of paleoclimate variations over recent centuries. This study suggests that n -alkane homologues are sensitive to vegetation and climate changes and thus are reliable biomarkers for tracking past shifts in vegetation and climate variations in peat archives. • Determine organic matter source of peat sediments from n -alkane biomarkers. • C 23 /(C 27 +C 31) n -alkane proxy is proposed and can effectively characterize climate changes. • P aq proxy indication could be misleading when the contribution of Sphagnum fuscum to the peat is large. • n -Alkan-2-one proxy is studied to further confirm the biomarker-based reconstruction of paleoclimatic changes.

Purpose: Incarceration provides an opportunity for screening and treatment of sexually transmitted and blood-borne infections (STBBIs) in high-risk groups. The purpose of this paper is to determine positivity rates of STBBI screening within correctional facilities using opt-in strategies and estimate the proportion of admissions tested.Design/methodology/approach: A cross-sectional, retrospective review of testing data from January 2012 to August 2015 from three provincial correctional facilities located in Alberta, Canada was completed. Analysis variables included STBBI, gender, facility, collection year and age. STBBI-stratified analysis was performed to identify correlates for positivity using univariate and logistic regressions.Findings: Overall prevalence of chlamydia was 11.2 percent and gonorrhea was 3.5 percent; correlates for both were younger age and facility type. The syphilis prevalence rate was 3.2 percent; correlates included being female, older age, adult facilities, with later years being protective. In total, 14 (0.3 percent) newly diagnosed HIV cases were found, prevalence increased with age. HBV prevalence was 1.7 percent with no significant correlations. Nearly one-tenth (n=422) of those screened for HCV antibody were positive; all variables were significantly correlated. Overall estimates of the proportion of admissions tested by STBBI were low and ranged from 4.8 to 16.1 percent.Originality/value: This study found high rates of STBBI in correctional facilities and showed that only a small proportion of the population was tested using an opt-in strategy. Shifting to an "opt-out" strategy may be warranted. [ABSTRACT FROM AUTHOR]

Religious groups and churches have always played, and continue to play, vital roles in the settlement and integration of newcomers to Canada. In the 1980s, several not-for-profit agencies emerged with Catholic and Mennonite roots to respond to the arrival of thousands of refugees to the province from Southeast Asia and Central America. Today, these agencies are particularly interesting as they both challenge prevailing views on secularization and the provision of public services, and play an exceptionally active role in providing services to newcomers. This paper explores the interplay between the prevalence of a liberal secular ideology in Canada and the shifting identities of faith-based organizations in Alberta. Based on archival research and interviews, this paper demonstrates that it is the shifting and, often conflicting, views of staff and volunteers that have contributed to the secularization of identities in most of these agencies.

Freely-available satellite data streams and the ability to process these data on cloud-computing platforms such as Google Earth Engine have made frequent, large-scale landcover mapping at high resolution a real possibility. In this paper we apply these technologies, along with machine learning, to the mapping of peatlands–a landcover class that is critical for preserving biodiversity, helping to address climate change impacts, and providing ecosystem services, e.g., carbon storage–in the Boreal Forest Natural Region of Alberta, Canada. We outline a data-driven, scientific framework that: compiles large amounts of Earth observation data sets (radar, optical, and LiDAR); examines the extracted variables for suitability in peatland modelling; optimizes model parameterization; and finally, predicts peatland occurrence across a large boreal area (397, 958 km2) of Alberta at 10 m spatial resolution (equalling 3.9 billion pixels across Alberta). The resulting peatland occurrence model shows an accuracy of 87% and a kappa statistic of 0.57 when compared to our validation data set. Differentiating peatlands from mineral wetlands achieved an accuracy of 69% and kappa statistic of 0.37. This data-driven approach is applicable at large geopolitical scales (e.g., provincial, national) for wetland and landcover inventories that support long-term, responsible resource management.

Aim: This paper outlines the transformation of youth mental health services in Edmonton, Alberta, a large city in Western Canada. We describe the processes and challenges involved in restructuring how services and care are delivered to youth (11‐25 years old) with mental health needs based on the objectives of the pan‐Canadian ACCESS Open Minds network. Methods: We provide a narrative review of how youth mental health services have developed since our engagement with the ACCESS Open Minds initiative, based on its five central objectives of early identification, rapid access, appropriate care, continuity of care, and youth and family engagement. Results: Building on an initial community mapping exercise, a service network has been developed; teams that were previously age‐oriented have been integrated together to seamlessly cover the age 11 to 25 range; early identification has thus far focused on high‐school populations; and an actual drop‐in space facilitates rapid access and linkages to appropriate care within the 30‐day benchmark. Conclusions: Initial aspects of the transformation have relied on restructuring and partnerships that have generated early successes. However, further transformation over the longer term will depend on data demonstrating how this has impacted clinical outcomes and service utilization. Ultimately, sustainability in a large urban centre will likely involve scaling up to a network of similar services to cover the entire population of the city. [ABSTRACT FROM AUTHOR]

Polycyclic aromatic hydrocarbons (PAHs) are persistent pollutants of concern. A process-based model of the PAH degradation can improve our understanding of ecological drivers and processes. In this paper, a process-based biogeochemistry model, DeNitrification-DeComposition (DNDC) is modified to simulate the dynamics of PAHs degradation in soils at abandoned oil and gas well sites. This new version of DNDC-Organic Pollutants, called DNDC-OP, coupled the rates of PAH degradation with dynamics of soil, vegetation and climate, such as soil moisture and temperature. The model was parameterized and validated against datasets of four soil PAHs: pyrene, fluorene, chrysene and anthracene, at three different abandoned oil and gas well site locations in Alberta, Canada. The sensitivity of the parameters was analyzed and tested. The simulated results were in good agreement with the measured data with a coefficient of determination (R²) of 70 to 97%, and the root mean square error (RMSE) of 4.5 to 9.1 at all three sites. We also evaluated the influence of environmental factors, such as soil temperature and moisture, on the degradation of PAHs. An increased degradation of all four PAHs occurred with increasing soil moisture content. An increase of soil temperature from 10 to 20°C and subsequently to 25°C resulted in a decreased appearance of all four PAHs from the three well sites. The result shows that this model can be used as a tool for evaluating PAH degradation for effective reclamation strategies. [ABSTRACT FROM AUTHOR]

Hourly near-surface relative humidity and temperature were monitored from 2005 to 2010 in a mesoscale network of 232 sites in the foothills of the Rocky Mountains in southwestern Alberta, Canada. The monitoring network covers a range of elevations from 890 to 2880 m above sea level and an area of about 18 000 km 2 , sampling a variety of topographic settings and surface environments with an average spatial density of one station per 78 km 2. Having been combined with air pressure measurements from Calgary International Airport and adjusted for the site elevation, the hourly data form the basis of estimates of daily mean specific humidity, vapour pressure, and relative humidity at each site, available at 10.1594/PANGAEA.889435. Overall data coverage for the study period is 89 %. This paper describes the processing methods used to quality control and gap fill the data. Inverse-distance weighting techniques are used to estimate the missing 11 % of data, based on neighbourhood values of daily mean specific humidity. We also report monthly mean lapse rates of specific and relative humidity. Plots of seasonal and spatial humidity patterns in the region illustrate the relations between humidity variables and temperature, elevation, and longitude. [ABSTRACT FROM AUTHOR]

Alberta, Canada, passed a Sexual Sterilization Act in 1928 and up until its repeal in 1972, over 2,800 people were sterilized. Women were overrepresented in the number of sterilizations performed. This paper explores how changing understandings of eugenics led to a subtle transformation which resulted in a “two-pronged” system that targeted mentally defective men, often a danger to society, and mentally normal but morally abnormal women who consented to sterilization. The end result was success for the movement in terms of the types and numbers of people sterilized, and in the longevity of the program. [ABSTRACT FROM AUTHOR]

Large-scale oil production from oil sands deposits in Alberta, Canada has raised concerns about environmental impacts, such as the magnitude of air pollution emissions. This paper reports compound emission rates (E) for 69–89 nonbiogenic volatile organic compounds (VOCs) for each of four surface mining facilities, determined with a top-down approach using aircraft measurements in the summer of 2013. The aggregate emission rate (aE) of the nonbiogenic VOCs ranged from 50 ± 14 to 70 ± 22 t/d depending on the facility. In comparison, equivalent VOC emission rates reported to the Canadian National Pollutant Release Inventory (NPRI) using accepted estimation methods were lower than the aE values by factors of 2.0 ± 0.6, 3.1 ± 1.1, 4.5 ± 1.5, and 4.1 ± 1.6 for the four facilities, indicating underestimation in the reported VOC emissions. For 11 of the combined 93 VOC species reported by all four facilities, the reported emission rate and E were similar; but for the other 82 species, the reported emission rate was lower than E. The median ratio of E to that reported for all species by a facility ranged from 4.5 to 375 depending on the facility. Moreover, between 9 and 53 VOCs, for which there are existing reporting requirements to the NPRI, were not included in the facility emission reports. The comparisons between the emission reports and measurement-based emission rates indicate that improvements to VOC emission estimation methods would enhance the accuracy and completeness of emission estimates and their applicability to environmental impact assessments of oil sands developments.

In this paper, I describe dividing practices in making up a specific medical-legal category-the revolving door patient-to identify, label, and direct the actions of particular people living with mental illness. The revolving door patient was a category that had been spoken of for some time, but became a formal legal subject with the introduction of the Alberta Mental Health Act 2010 and Community Treatment Orders (CTOs). I demonstrate how a rationale of control over unpredictable and dangerous individuals was primary in creating this new category, and that the characterization of the revolving door patient required a disciplinary technology to reduce danger. I argue that the CTO is a medical-legal technology that solves the problem of governing a subject in order to produce a patient that manages mental illness. I conclude by reflecting on how the narrative of the revolving door patient, and of mental illness more broadly, has implications for personal identity and tensions between care and control.

Drawing on case-study research from a rural, resource-based community in Alberta, Canada, this paper explores the social and economic context of substance abuse. Specifically, the linkages between social structure, community fragmentation, and family dysfunction offer a way of understanding differential resistance and susceptibility to substance abuse. Five thematic areas were linked to susceptibility in this study: (1) an economy based on multiple divergent sectors, which gives rise to income disparity and social inequality; (2) a highly transient population, which results in social distancing and lack of social support; (3) shift work, which prevents opportunities for consistent and productive family and community relationships; (4) high incomes, which lead to material competition and financial stress; and (5) a culture of entitlement, which produces certain expectations and perceived privileges among some workers and their families. Our findings are consistent with previous research on the link between substance abuse and shift work, work environments, and the social conditions in boomtowns. But this paper also identifies novel themes, such as high incomes and a culture of entitlement, and introduces the notion of slow disasters and cumulative risk histories to help explain susceptibility to substance abuse within this rural community.

This paper outlines the issues surrounding a recent move by the Government of Alberta, Canada to lower the accepted working age to 12 years old. The paper places this decision within the wider context of changes in labour standards in North America and internationally. The lowering of the working age not only contravenes the principles of international labour agreements but is also in tension with other social policy aimed at reducing child poverty, increasing school completion rates, and providing effective transitions for youth.

Rational choice theory suggests that parents are utility maximizers who make decisions from clear value preferences, that they are able to demand effective action from local schools and teachers, and that they can be relied upon to pursue the best interests of their children. This paper presents a different perspective and argues that parents invest a mixture of rationalities when selecting schools. Based on the results of a survey of 1,500 parents of students in 11 private, eight public and 10 alter- native elementary schools in Alberta, Canada, this paper explores the logic, values, and concerns that inform parental decision making in the selection of an elementary school for their children and discusses implication for policy and educational reform.

This paper reports on the development of a 'suitability for practice' policy in a large Canadian school of social work. Pertinent gatekeeping issues are reviewed and the results of a survey on suitability polices in Canadian social work schools are presented. The paper concludes with a discussion of the University of Calgary's Faculty of Social Work Suitability Policy. This policy integrates current research on gatekeeping, the results of the Canadian schools survey and input from primary stakeholders: the students, faculty members, the professional association and the community.

The last fifteen years of the twentieth century have witnessed fundamental changes in approaches to the issue of youth prostitution in Canada. During this period there has been a growing recognition that young prostitutes should be treated as victims in need of protection, not deviants requiring punishment. The most recent and controversial policy response to this victimization framework has been the introduction of secure care legislation in the province of Alberta. Discussions around the possibility of introducing similar legislation has taken place in British Columbia and Ontario. This paper argues the secure care movement in the provinces of Alberta and British Columbia represent neo-liberal responses to the (re) conceptualization of youth prostitution as a form of sexual abuse and exploitation. Of particular interest is how secure care advances neo-liberal forms of governance by supporting what Garland refers to as ‘responsibilization’ strategies. In the process, the youth prostitution ‘problem’ is governed at a distance, the onus for combatting the youth sex trade is placed upon the individual prostitute, community and family, and the meaning of ‘success’ in addressing the youth prostitution phenomenon is redefined. At the same time, relations of power that give rise to the youth sex trade remain unchallenged. The paper concludes by suggesting ways of challenging neo-liberal strategies of controlling the youth sex trade. [ABSTRACT FROM AUTHOR]

Policy makers in a variety of sites are embracing initiatives that attempt to tighten the links between school and work. A reinvented human capital discourse argues that more highly skilled workers are required to meet the demands of the 'knowledge economy'. This paper explores the new vocationalism as it is promoted within the Framework for Enhancing Business Involvement, a policy report produced in 1996 in Alberta, Canada. Using a critical policy approach, this paper focuses on the process of developing this document with attention to the policy context, influences on the process, ideological assumptions and the impact of the document since its release. Analysis suggests that questions of representation in policy processes, accountability for outcomes and the role of public interests in multi-stakeholder consultation are critical in this era of new public management practices. Further, despite the impression of unity and consensus suggested by policy documents, there are tensions in vocational education and policy that must be addressed if they are also to promote equity.

Recent media accounts suggest certain faith-based interest groups are increasingly pressuring provincial governments across Canada to ensure their views on education policy are acted upon. This paper offers a qualitative assessment of the policy influence possessed by faithbased groups active on the education file in Alberta and the factors responsible for this level of influence. Overall, such influence is not directly attributable to the group's size or resources nor can it be explained by the assumption that Alberta is overrun with religious citizens demanding socially conservative policies. Rather, the explanation is found in a more nuanced appreciation of the self-interested electoral calculations made by the long-governing Progressive Conservative party, on the one hand, as well as well as the party's long-running commitment to "school choice" on the other. This sentiment is intimately related to both the province's populist political culture as well as a broader ideological convergence around the principle of "free choice" in general, and the benefits of marketization in particular.

This paper discusses the coverage given to Ukrainian Canadian topics in two Alberta newspapers, the Edmonton Journal and the Edmonton Bulletin, during the World War II years. Examples of the subjects included in the essay are Ukrainian Canadian participation in the war effort through enlistments in the Canadian armed forces and other ways, the banning of the Ukrainian Labour-Farmer Temple Association, the formation of the Ukrainian Canadian Committee, the raising of the matter of Ukrainian independence, and the Canadian conscription plebiscite of 27 April 1942. The two newspapers published in the provincial capital accorded significant attention to Ukrainian Canadian issues, a coverage that was paralleled by the many stories that related to Ukraine, a major battleground in the war.
