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.

Objective: To explore the barriers associated with the adoption of the Alberta Nutrition Guidelines for Children and Youth in schools according to characteristics of the innovation (guidelines) and the organization (schools). Design: Cross-sectional telephone survey. Setting and Participants: Schools in Alberta, Canada. Principals from 357 schools. Main Outcome Measure: Barriers to adopting the nutrition guidelines. Analysis: A 19-question telephone survey, including open- and closed-ended questions, was used to obtain information regarding schools' characteristics and barriers to adopting the guidelines. Qualitative data were coded according to common themes a priori, based on constructs from the Diffusion of Innovations framework. Results: Schools reported many barriers related to the relative advantage, compatibility, and complexity of adopting the guidelines. Parents' resistance to change and cost were the key reported barriers. Lack of knowledge, student preferences, the physical location of the school, and barriers related to the provision of healthful food were also reported. Conclusions and Implications: Disseminating guidelines without providing adequate support for their implementation may not promote change within the school setting. School nutrition initiatives need to involve the parents and have access to sufficient financial and human resource support. [ABSTRACT FROM AUTHOR]

Top-down approaches to measure total integrated emissions provide verification of bottom-up, temporally-resolved, inventory-based estimations. Aircraft-based measurements of air pollutants from sources in the Canadian oil sands were made in support of the Joint Canada-Alberta Implementation Plan on Oil Sands Monitoring during a summer intensive field campaign between 13 August and 7 September 2013. The measurements contribute to knowledge needed in support of the Joint Canada-Alberta Implementation Plan on Oil Sands Monitoring. This paper describes a Top-down Emission Rate Retrieval Algorithm (TERRA) to determine facility emissions of pollutants, using SO2 and CH4 as examples, based on the aircraft measurements. In this algorithm, the flight path around a facility at multiple heights is mapped to a two-dimensional vertical screen surrounding the facility. The total transport of SO2 and CH4 through this screen is calculated using aircraft wind measurements, and facility emissions are then calculated based on the divergence theorem with estimations of box-top losses, hori zontal and vertical turbulent fluxes, surface deposition, and apparent losses due to air densification and chemical reaction. Example calculations for two separate flights are presented. During an upset condition of SO2 emissions on one day, these calculations are within 5% of the industry-reported, bottom-up measurements. During a return to normal operating conditions, the SO2 emissions are within 11% of industry-reported, bottom-up measurements. CH4 emissions calculated with the algorithm are relatively constant within the range of uncertainties. Uncertainty of the emission rates is estimated as 20 %, which is primarily due to the unknown SO2 and CH4 mixing ratios near the surface below the lowest flight level. [ABSTRACT FROM AUTHOR]

Aims: To investigate the feasibility and acceptability of a serious mobile-game intervention on older adults' engagement, affect, and cognitive function. Methods: In this single-subject design, twenty older adults, six of whom living with dementia, participated in a 16-session mobile-game intervention. Before and after the intervention, participants had sessions involving traditional paper-based cognitive activities. Engagement and affect were measured in each session. Cognitive measures were administered before and after the intervention. Acceptability was explored through interviews. Results: After the intervention, there was a statistically significant increase in engagement in 37% of participants, and in affect in 21% of participants. Participants preferred the mobile games to the paper-based activities. Cognitive measures showed improvement in four participants with dementia. Conclusions: Although not conclusive, participants experienced higher levels of engagement and positive affect while playing the mobile games compared to paper-based activities. The results indicate feasibility and acceptability of the mobile game intervention. [ABSTRACT FROM AUTHOR]

This article examines the benefits that experiential learning affords both students and organizations where there is sharing and participating in "real world learning." Mount Royal University Calgary, Alberta, seeks to incorporate experiential learning opportunities in most undergraduate degree programs, for example, the Department of Economics, Justice and Policy Studies, and the Department of Child Studies and Social Work. Experiential Service learning is geared toward improving student engagement and leadership. In the summer of 2021, students collaboratively developed a policy paper on how police could improve their capacity to investigate and combat cyber crimes. The policy paper was developed during COVID-19, which required creativity associated with remote learning. Drawing on literature that highlights experiential learning, this paper highlights the experience of students in Justice Policy Studies who benefitted by integrating critical course content and collaborating with community stakeholders.

This article empirically examines the ways in which Initial Teacher Education in Scotland and Alberta, Canada, seeks to 'get students in', 'get them out and into the workforce', 'get on with teaching future teachers' and how it should 'get on with students'. Using Adams' (2016) policy heuristic, which posits that policy can be discerned in three realms: frame; explanation; and formation, this paper considers the middle realm: that of policy explanation. Here, attempts to position policy through public pronouncement, policy directive, mandate and/or missive are examined in the context of ITE in Scotland and Alberta. By analysing policy explanations, the paper marks out how both jurisdictions should begin to attempt to craft ITE located in career-long, professional learning and development that understands and acknowledges tensions between ITE and later teacher-education phases. Finally, the paper makes a tentative proposal as to what such ITE might hope to achieve and how it might contribute to a well-developed workforce, so that both locations and other jurisdictions might orient initial teacher development.

This paper considers small businesses as an effective sector that solves current problems in the structure of the economy. The study aims to develop a set of measures (tools) for involving small businesses in stabilizing Alberta's economy. The methodology includes the monitoring of the economy within Alberta's regional borders over time; statistical analysis of the small business sector before and during the pandemic in the structure of the economy; as well as grouping and converting quantitative measurements into a qualitative summary of the main economic principles. These steps are aimed at developing a set of measures (tools) for involving small businesses in the economy of the province and the country as a whole. The growth of small enterprises ensures a practice focused on productivity, innovation, and society, which is confirmed by the dominant share of small businesses in the gross domestic product created by the dominant share of small businesses in the gross domestic product created by the private sector of the province. Thus, focusing on the economic principles of small businesses, a complex of measures is proposed for mobilization to maximize the economic result at the provincial level in the context of strengthening the national economy. In practice, the findings will help the local government to determine a set of beneficial policies, contributing to the utilization of the advantages of the local economy in the sphere of business production. Entrepreneurs are provided with an opportunity to qualitatively utilize economic opportunities, recognizing the risks of the external environment. [ABSTRACT FROM AUTHOR]

Effective winter road maintenance relies on precise road friction estimation. Machine learning (ML) models have shown significant promise in this; however, their inherent complexity makes understanding their inner workings challenging. This paper addresses this issue by conducting a comparative analysis of road friction estimation models using four ML methods, including regression tree, random forest, eXtreme Gradient Boosting (XGBoost), and support vector regression (SVR). We then employ the SHapley Additive exPlanations (SHAP) explainable artificial intelligence (AI) to enhance model interpretability. Our analysis on an Alberta dataset reveals that the XGBoost model performs best with an accuracy of 91.39%. The SHAP analysis illustrates the logical relationships between predictor features and friction within all three tree-based models, but it also uncovers inconsistencies within the SVR model, potentially attributed to insufficient feature interactions. Thus, this paper not only showcase the role of explainable AI in improving the ML interpretability of models for road friction estimation, but also provides practical insights that could improve winter road maintenance decisions.

A number of sentinel species are regularly sampled from the environment near the Oil Sands Region (OSR) in Alberta, Canada. In particular, trout-perch are sampled as a proxy for the health of the aquatic ecosystem. As the development of the OSR began before the environmental monitoring program was in place, there is currently no established measure for the baseline health of the local ecosystem. A common solution is to calculate normal ranges for fish endpoints. Observations found to be outside the normal range are then flagged, alerting researchers to the potential presence of stressors in the local environment. The quality of the normal ranges is dependent on the accuracy of the estimates used to calculate them. This paper explores the use of neural networks and regularized regression for improving the prediction accuracy of fish endpoints. We also consider the trade-off between the prediction accuracy and interpretability of each model. We find that neural networks can provide increased prediction accuracy, but this improvement in accuracy may not be worth the loss in interpretability in some ecological studies. The elastic net offers both good prediction accuracy and interpretability, making it a safe choice for many ecological applications. A hybridized method combining both the neural network and elastic net offers high prediction accuracy as well as some interpretability, and therefore it is the recommended method for this application.

This review paper investigates the landscape of wildfire-related studies with a focus on infrastructure and evacuations across Canadian provinces, revealing a predominant focus on Alberta, particularly after the 2016 Fort McMurray wildfire. The aftermath of this event has heightened attention to the unique challenges faced during evacuations, emphasizing the urgent need for heightened awareness and preparedness, especially in the vulnerable northern communities of Alberta. Studies beyond Alberta contribute to understanding Canadian wildfire dynamics. However, a noticeable research gap in British Columbia raises concerns about research prioritization and resource allocation despite heightened wildfire activity. The fact that some provinces are contributing less than 4.2%, such as Quebec, Saskatchewan, Ontario, Northwest Territories, Yukon, and the Prairies, might be attributed to regional variations influenced by historical wildfire frequency and population density. Thematic analysis categorizing studies into "community support/resilience", "evacuation efficiency", and "infrastructure protection/raising awareness" provides nuanced insights. The dominance of the "community support/resilience" category, comprising over 40% of studies, signifies a societal shift towards proactive community engagement. Balanced representation in the "evacuation efficiency" and "infrastructure protection/raising awareness" categories, each contributing over 29%, reflects a collective effort to glean lessons from past evacuations and enhance community preparedness. Temporal trends and thematic analyses spotlight a commitment to continuous improvement, adaptability to emerging challenges, and a growing recognition of the multifaceted aspects of wildfire management. The evolving emphasis on community involvement, responsiveness to changing evacuation dynamics, and heightened awareness of infrastructure protection underscores the proactive stance of the research community, providing insights for shaping future research priorities, policy frameworks, and community resilience strategies in the face of evolving wildfire threats in Canada.

Background: Medical Assistance in Dying (MAiD) was legalized in Canada in 2016 and amended in 2021. At the time that this study was conducted, the federal government was considering expanding the eligibility criteria to include patients whose death was not reasonably foreseeable. The purpose of this study was to better understand rural healthcare professionals' experiences with assisted dying set against the backdrop of legislative expansion. Methods: A qualitative exploratory study was undertaken with general rural practice physicians, nurse practitioners, registered nurses, ethicists, patients, and patient families in rural Southern Alberta, Canada. For this paper, data from 18 audio-recorded and transcribed semi-structured interviews with healthcare professionals were analyzed using thematic analysis. Categories and patterns of shared meaning that linked to an overarching theme were identified. Results: Between the binary positions of full support for and conscientious objection to assisted dying, rural healthcare professionals' decisions to participate in MAiD was based on their moral convictions, various contextual factors, and their participation thresholds. Factors including patient suffering; personal and professional values and beliefs; relationships with colleagues, patients and family, and community; and changing MAiD policy and legislation created nuances that informed their decision-making. Conclusions: The interplay of multiple factors and their degree of influence on healthcare professionals' decision-making create multiple decision points between full support for and participation in MAiD processes and complete opposition and/or abstention. Moreover, our findings suggest evolving policy and legislation have the potential to increase rural healthcare professionals' uncertainty and level of discomfort in providing services. We propose that the binary language typically used in the MAiD discourse be reframed to reflect that decision-making processes and actions are often fluid and situational. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 (C19) pandemic shocked primary care systems around the world. Those systems responded by supporting patients in the community, and acute care facilities in crisis. In Canada, the Patient Medical Home (PMH) is a widely adopted care model that aims to operationalize the tenets and principles of Primary Health Care (PHC) as developed since the Alma-Ata Declaration. This paper describes how personnel working in and with Primary Care Networks (PCNs) in Alberta, Canada deployed the PMH model and its underlying PHC principles to frame and respond to the C19 shock. Methods: Using purposive and snowball sampling techniques, we interviewed 57 participants who worked in public health and primary care, including community-based family physicians. We used interpretive description to analyze the interviews. Results: PCN staff and physicians described how the PMH model was foundational to normal operations, and how C19 responses were framed by the patient-centric, team-delivered, and continuous care principles the model shares with PHC. Specifically, participants described ensuring access to care, addressing the social determinants of health, being patient centered, and redeploying and expanding PHC teams to accomplish these goals. Discussion: Delivering PHC through the PMH allowed physicians and allied health staff to deliver patient-centered, team-based, holistic bio-medical services to Albertans. In tailoring services to meet the specific social and health needs of the populations served by each PCN, healthcare providers were able to ensure relevant support remained available and accessible.

Pope Francis's dream for a synodal Church has implications for Catholic schools globally, but what exactly are these consequences? This paper explores Francis's vision in the context of Canadian Catholic schools in Alberta, Saskatchewan, and the Northwest Territories (NWT), where these schools are fully-funded by the government and enroll nearly a quarter million students. Ten exploratory interviews with chief superintendents from these schools—which formed the basis of a larger study—were analyzed to understand potential connections to Francis's vision and his four commitments to synodality: focusing on relationships, a culture of encounter, the essentials of the Christian faith, and local decision-making. The pope differentiates synodality from democratic forms of leadership and demands a communal form of listening and discerning God's Spirit. While the superintendents' style of leadership appeared to mirror synodality in many ways, predominant issues remain to be explored: an emphasis on relationships upends the status quo and gives new directions for the schools; encountering others will inevitably demand prophetic leadership by the system leaders; leading with the essentials of faith will not please everyone in Catholic schooling; and shared authority among the superintendents, bishops, and trustees requires further dialogue.

Season of seeding and soil amendment with manure mix, wood shavings and erosion control blankets were evaluated over two growing seasons to determine their effect on soil properties and native grass establishment at a Canadian limestone quarry and lime processing plant. Season (fall, spring) of soil amending and seeding did not significantly affect revegetation or soil properties. Site characteristics such as slope, aspect, initial soil nutrients and surrounding plant communities influenced early plant community development and overall effects of soil treatments. Erosion control blankets resulted in the highest seeded plant cover and the lowest non seeded plant cover despite not significantly changing soil chemical properties. Total nitrogen and carbon significantly increased establishment of seeded grasses and non seeded species. Increased nitrogen and carbon in the constructed soils were best achieved through addition of manure. Wood shavings did not favour establishment of vegetation and resulted in similar, and in some cases less, vegetation than controls. Assisted revegetation increased plant cover from <6 to 50% and reduced cover of non seeded species. Amendments that modified both chemical and physical soil conditions were best to increase vegetation establishment in the harsh conditions of the quarry. [ABSTRACT FROM AUTHOR]

The majority of previous studies on reliability-based highway design focussed on assessing the risk associated with only one mode of non-compliance (i.e. insufficient sight distance on horizontal curves using 2 D sight distance calculations). Only a handful number of studies established a link between risk levels and collisions. This paper calibrates safety-based design charts for horizontal curves considering a system reliability analysis (i.e., multi-mode) where the non-compliance could result from limited sight distance and vehicle skidding. The paper first utilised LiDAR data to collect curve attributes and assess the Available Sight Distance in a 3 D environment on 244 horizontal curves in Alberta, Canada. Monte Carlo Simulation was then used to calculate the associated risk levels, and full-Bayes multivariate Poisson lognormal regression was utilised to develop statistically significant safety performance functions that relate risk levels to collisions. Safety-based design charts were calibrated to relate curve attributes to risk levels and collisions. The calibrated charts showed the importance of using multi-mode reliability analysis. An example of using the calibrated charts in estimating the expected safety benefits of geometric improvements was introduced. The developed charts can offer designers a tool to estimate the safety consequences of design alternatives and aid the decision-making process of rehabilitation projects. [ABSTRACT FROM AUTHOR]

In Fall 2020, all universities in Alberta went with remote delivery of classes due to COVID-19 restrictions. This provided not only teaching challenges, but also opportunities. Professors at three Canadian universities teaching similar undergraduate courses in international political economy decided to use the challenges/opportunities of COVID-19 restrictions to experiment with a World Trade Organization (WTO) simulation across three campuses through remote delivery. Simulations are frequently used for teaching in political science, but what was unusual was doing it through remote delivery. This paper assesses the effectiveness of the experiment. It traces the origins/evolution of the idea, learning objectives for the students, preparation by the professors to design the WTO simulation, and the experience of the actual simulation. It also addresses the challenges (technological, timing, assignments, grading, student anxiety, etc.). In addition, it identifies the steps that were taken to reduce and mitigate the challenges. It also acknowledges the mistakes that were made by the professors in designing and implementing the assignment. These observations and reflections are informed by the materials that the professors prepared, their thoughts on the experience, and the feedback from participating students (through official student evaluations as well as a special survey instrument). It provides lessons for future online simulations. [ABSTRACT FROM AUTHOR]

Basal gravel and sand mantling the bedrock floors of buried valleys throughout the Canadian Interior Plains, and conformably overlying proglacial lacustrine sediment, comprise the Empress Group. While previously conceptualized as stratigraphically equivalent deposits of preglacial rivers prior to the first and most extensive continental and montane glaciations, subsequent stratigraphic studies indicated that buried valley basal gravel must have been deposited between, or during, progressively more extensive continental glaciations and could not be stratigraphically equivalent throughout the buried valley network. However, in the general absence of formation-rank stratigraphic description of basal gravel units that might better inform the geologic history of the deposits, most workers simply consider Empress Group sediments time-transgressive. In this paper, we examine basal gravel at provincial and regional scales to understand its genesis and geologic history. At the provincial scale, we map basal gravel in three dimensions using a novel machine learning approach. At the regional scale, we formally define basal gravel formations at either end of the largest buried valley system in Alberta, which informs its glacial history and physiographic development and shows the importance of formation-rank stratigraphic description. Our results indicate that the buried valley network across Alberta is palimpsest in genesis and basal gravel units within it are chronostratigraphically intercalated between tills. We advocate that the Empress Group definition be extended across Alberta with modifications to improve its clarity and utility, and formally define the Old Fort, Unchaga, Ipiatik, and Winefred formations as part of the Empress Group.

In the past decade, a large volume of peer‐reviewed papers has examined the potential impacts of oil and gas resource extraction in the Canadian oil sands (OS). A large proportion focuses on terrestrial biology: wildlife, birds, and vegetation. We provide a qualitative synthesis of the condition of the environment in the oil sands region (OSR) from 2009 to 2020 to identify gaps and progress cumulative effects assessments. Our objectives were to (1) qualitatively synthesize and critically review knowledge from the OSR; (2) identify consistent trends and generalizable conclusions; and (3) pinpoint gaps in need of greater monitoring or research effort. We visualize knowledge and terrestrial monitoring foci by allocating papers to a conceptual model for the OS. Despite a recent increase in publications, focus has remained concentrated on a few key stressors, especially landscape disturbance, and a few taxa of interest. Stressor and response monitoring is well represented, but direct monitoring of pathways (linkages between stressors and responses) is limited. Important knowledge gaps include understanding effects at multiple spatial scales, mammal health effects monitoring, focused monitoring of local resources important to Indigenous communities, and geospatial coverage and availability, including higher attribute resolution in human footprint, comprehensive land cover mapping, and up‐to‐date LiDAR coverage. Causal attribution based on spatial proximity to operations or spatial orientation of monitoring in the region is common but may be limited in the strength of inference that it provides.

The desire to document and understand the cumulative implications of oil sands (OS) development in the ambient environment of northeastern Alberta has motivated increased investment and release of information in the past decade. Here, we summarize the knowledge presented in the theme‐based review papers in this special series, including air, surface water, terrestrial biology, and Indigenous community‐based monitoring in order to (1) consolidate knowledge gained to date, (2) highlight key commonalities and gaps, and (3) leverage this knowledge to assess the state of integration in environmental monitoring efforts in the OS region and suggest next steps. Among air, water, and land studies, the individual reviews identified a clear focus on describing stressors, including primarily (1) contaminant emission, transport, transformation, deposition, and exposure, and (2) landscape disturbance. These emphases are generally partitioned by theme; air and water studies focus heavily on chemical stressors, whereas terrestrial monitoring focuses on biological change and landscape disturbance. Causal attribution is often stated as a high priority objective across all themes. However, studies often rely on spatial proximity to attribute cause to industrial activity, leaving causal attribution potentially confounded by spatial covariance of both OS‐ and non‐OS‐related stressors in the region, and by the complexity of interacting pathways between sources of environmental change and ecological receptors. Geospatial and modeling approaches are common across themes and may represent clear integration opportunities, particularly to help inform investigation‐of‐cause, but are not a replacement for robust field monitoring designs. Cumulative effects assessment remains a common focus of regional monitoring, but is limited in the peer‐reviewed literature, potentially reflecting a lack of integration among monitoring efforts beyond narrow integrated interpretations of results. Addressing this requires greater emphasis on a priori integrated data collection and integrated analyses focused on the main residual exposure pathways, such as atmospheric deposition. Integr Environ Assess Manag 2022;18:428–441. © 2021 The Authors. Integrated Environmental Assessment and Management published by Wiley Periodicals LLC on behalf of Society of Environmental Toxicology & Chemistry (SETAC). KEY POINTS: Our summary of the peer‐reviewed literature since 2010 from the Alberta oil sands region reveals an emphasis on chemical stressors and their association with atmospheric emissions, transport, transformation, and deposition, as well as an emphasis on landscape disturbance and associated effects.System‐wide gaps in the literature, including topics of concern to local Indigenous communities, derive from a disconnect between theme areas (air, water, land), contribute to an incomplete knowledge of functional linkages, and may undermine the ability to inform regulatory or policy action.Combining papers not explicitly designed together creates interpretative and analytical challenges, and overcoming these may require future optimization of and integration between targeted monitoring projects and entire theme areas.

Over the past decades, concerns regarding the local and cumulative impacts of oil sands development have been increasing. These concerns reflect the industry's emissions, land disturbance, water use, and the resulting impacts to Indigenous Rights. Effective environmental management is essential to address and ultimately manage these concerns. A series of ambient regional monitoring programs in the oil sands region (OSR) have struggled with scope and governance. In the last 10 years, monitoring has evolved from a regulatory‐driven exercise implemented by industry into a focused, collaborative, multistakeholder program that attempts to integrate rigorous science from a multitude of disciplines and ways of knowing. Monitoring in the region continues to grapple with leadership, governance, data management, scope, and effective analysis and reporting. This special series, "A Decade of Research and Monitoring in the Oil Sands Region of Alberta, Canada," provides a series of critical reviews that synthesize 10 years of published monitoring results to identify patterns of consistent ecological responses or effects, significant gaps in knowledge, and recommendations for improved monitoring, assessment, and management of the region. The special series considered over 300 peer‐reviewed papers and represents the first integrated critical review of the published literature from the region. This introductory paper of the series introduces the history of ambient environmental monitoring in the OSR and discusses historic and ongoing challenges with the environmental monitoring effort. While significant progress has been made in areas of governance, expanded geographical scope, and inclusion of Indigenous communities in monitoring in the region, significant issues remain regarding a lack of integrated reporting on environmental conditions, public access to data, and continuity of monitoring efforts over time.

Purpose: This study examines the competencies delineated by the Chartered Professional Accountants (CPA) in Canada and explores the gap between what universities provide, represented by the students' confidence in the knowledge acquired—and what the accounting profession in Canada requires and deems necessary. Design/methodology/approach: Using the 44 sub-competencies listed under the main seven competencies set by CPA, a pair of questionnaires were drafted. The first questionnaire asked post-secondary accounting students to rate their perceived confidence in these 44 sub-competencies and received 105 responses. The second questionnaire asked accounting professionals to rate the frequency and degree of use of each sub-competency in their workplace and received 72 responses. The responses to the two questionnaires were used to compare perceived student competencies with industry expectations. Findings: The study suggests an industry-neutral framework that employers and post-secondary institutions (PSIs) can use to determine where knowledge gaps exist between students' qualifications and professionals' requirements. The paper concludes that while there are synergies in many competencies in the accounting field in Canada, there are also areas of discord. Research limitations/implications: The study relies on one accredited PSI. Relying on one case study limits the ability to generalize the findings. Nevertheless, the in-depth nature of the study allows it to shed light on many key issues related to accounting education and the profession in Alberta, Canada. Originality/value: This paper adds to the existing literature by exploring the gap between what students learn and what the profession needs in the accounting field in Canada. Studying Canada adds to the accounting knowledge and draws attention to gaps that could exist in other countries. To the authors' knowledge, this is the first paper to focus on Canada from this perspective. The paper also proposes a curriculum development model that is based on market needs and applicable to all fields of knowledge. [ABSTRACT FROM AUTHOR]

We investigated the relationship of stem diameter to tree, site and stand characteristics for six major tree species (trembling aspen, white birch, balsam fir, lodgepole pine, black spruce, and white spruce) in Alberta (Canada) with data from Alberta Sustainable Resource Development Permanent Sample Plots. Using non-linear mixed effects modeling techniques, we developed models to estimate diameter at breast height using height, crown and stand attributes. Mixed effects models (with plot as subject) using height, crown area, and basal area of the larger trees explained on average 95% of the variation in diameter at breast height across the six species with a root mean square error of 2.0 cm (13.4% of mean diameter). Fixed effects models (without plot as subject) including the Natural Sub-Region (NSR) information explained on average 90% of the variation in diameter at breast height across the six species with a root mean square error equal to 2.8 cm (17.9% of mean diameter). Selected climate variables provided similar results to models with NSR information. The inclusion of nutrient regime and moisture regime did not significantly improve the predictive ability of these models. [ABSTRACT FROM AUTHOR]

(1) Background: Transitioning from mental health inpatient care to community care is often a vulnerable time in the treatment process where additional risks and anxiety may arise. We collected data for this study as part of a pragmatic cluster-randomized, longitudinal approach in Alberta. As the first phase of the ongoing innovative supportive program, this paper assessed the progression of mental health symptoms in patients six weeks after hospital discharge. Factors that may contribute to the presence or absence of anxiety and depression symptoms, as well as well-being, following return to the community were investigated. This provides evidence and baseline data for future phases of the project. (2) Methods: An observational study design was adopted for this study. Data on a variety of sociodemographic and clinical factors were collected at discharge and six weeks after via REDCap. Anxiety, depression, and well-being symptoms were assessed using the Generalized Anxiety Disorder (GAD-7) questionnaire, the Patient Health Questionnaire-9 (PHQ-9), and the World Health Organization-Five Well-Being Index (WHO-5), respectively. Descriptive, chi-square, independent t-tests, and multivariate regression analyses were conducted. (3) Result: The survey was completed by 88 out of 306 participants (28.8% response rate). The chi-square/Fisher exact test and independent t-test revealed no significant change in the mental health conditions from baseline to six weeks after discharge. It was found that the only significant factor predicting symptoms six weeks after discharge from inpatient treatment was the baseline symptoms in all three logistic regression models. It was four times more likely for those who experienced anxiety and depression at baseline to experience anxiety and depression symptoms six weeks after discharge (OR = 4.27; 95% CI: 1.38–13.20) (OR = 4.04; 95% CI: 1.25–13.05). Those with poor baseline well-being were almost 12 times more likely to experience poor well-being six weeks after discharge (OR = 11.75; 95% CI: 3.21–42.99). (4) Conclusions: Study results found no significant change in mental health conditions in the short term following hospital discharge. It is essential that researchers and policymakers collaborate in order to implement effective interventions to support and maintain the mental health conditions of patients following discharge.

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.

Background: The transition from hospital to community settings for most mental health service users is often hindered by challenges that affect community adjustment and continuity of care. The first few weeks and days after discharge from mental health inpatient units represent a critical phase for many service users. This paper aims to evaluate the changes in the resilience, personal recovery, and quality of life status of individuals with mental health challenges recently discharged from acute mental health care into the community. Methods: Data for this study were collected as part of a pragmatic stepped-wedge cluster-randomized, longitudinal approach in Alberta. A paired sample t-test and Chi-squared/Fisher test were deployed to assess changes from baseline to six weeks in the recovery assessment scale (RAS), brief resilience scale (BRS), and EuroQol-5d (EQ-5D), using an online questionnaire. Results: A total of 306 service users were recruited and 88 completed both baseline and six weeks, giving a response rate of 28.8%. There was no statistically significant change in the level of resilience, recovery and quality of life as measured with the brief resilience scale, recovery assessment scale and EQ-5D from baseline to six weeks (p > 0.05). Conclusions: The study showed that there was neither an improvement nor deterioration in resilience, recovery, or quality of life status of service users six weeks post-discharge from inpatient mental health care. The lack of further progress calls into question whether the support available in the community when patient's leave inpatient care is adequate to promote full recovery. The results justify investigations into the effectiveness of innovative and cost-effective programs such as peer and text-based supportive interventions for service users discharged from inpatient psychiatric care.

The impact of cancer in Alberta is expected to grow considerably, largely driven by population growth and aging. The Future of Cancer Impact (FOCI) initiative offers an overview of the present state of cancer care in Alberta and highlights potential opportunities for research and innovation across the continuum. In this paper, we present a series of detailed projections and analyses regarding cancer epidemiological estimates in Alberta, Canada. Data on cancer incidence and mortality in Alberta (1998–2018) and limited-duration cancer prevalence in Alberta (2000–2019) were collected from the Alberta Cancer Registry. We used the Canproj package in the R software to project these epidemiological estimates up to the year 2040. To estimate the direct management costs, we ran a series of microsimulations using the OncoSim All Cancers Model. Our findings indicate that from 2020, the total number of annual new cancer cases and cancer-related deaths are projected to increase by 56% and 49% by 2040, respectively. From 2019, the five-year prevalence of all cancers in Alberta is projected to increase by 86% by 2040. In line with these trends, the overall direct cost of cancer management is estimated to increase by 53% in 2040. These estimates and projections are integral to future strategic planning and investment. [ABSTRACT FROM AUTHOR]

The notion that Housing First (HF) is a human-rights based approach to housing some of society's most vulnerable citizens is often alluded to in the literature, but seldom interrogated. In this paper, we examine whether HF in Alberta, Canada is practiced in a way that realizes the right to housing for chronically homeless people. We do so using four human rights principles identified by Fukuda-Parr: non-discrimination, participation, adequate progress and remedy. Based on interviews with staff of 14 HF programs in three cities, we identify constraints to a human rights-based approach, including time-limited support, which necessitates a strong emphasis on housing sustainability. We also identify positive practices, such as client participation in decision-making and tenant rights education. The paper also provides a model for systematically assessing whether HF programs respect, protect and fulfil the right to housing. [ABSTRACT FROM AUTHOR]

Birding is one of the most popular recreational activities, but bird populations have been declining worldwide. Understanding how much people benefit from local bird populations levels, species richness and their preferences can help inform bird conservation management. This paper uses eBird data and random utility models to assess the birders' preferences and welfare for trips to local areas. The sample eBird citizen science data includes 35,656 trips by 290 individual birders to 1227 unique birding hotspots in Alberta, Canada. The economic value of seeing one additional bird species during a trip is estimated to be $0.68 on average. We estimated a nonlinear relationship between the utility and number of bird species suggesting satiation in recreation preferences, and the highest MWTP is estimated to be in the summer and fall seasons. Bird species at risk, based on Alberta's strategy for the management of species at risk, are valued almost ten times higher as seeing other types of bird species. We also estimate individualized choice models and find that preference for species richness is heterogeneous across birders. Results of a combinatorial test find that the individualized choice models produce average welfare estimates that are 67% higher than the single model but the difference is not statistically significant. The members of eBird represent a convenience sample that may not constitute the general population. Thus along with proper weighting, these benefit estimates produced in this research can help inform future bird conservation management decisions including alternative funding mechanisms.

Objectives: To evaluate a new prenatal education program evaluation tool, the UpStart Parent Survey – Prenatal, in terms of: (a) reliability and validity; (b) sensitivity to change over time; (c) whether results differed for mothers versus fathers; and (d) whether results differed when using an electronic tablet‐computer versus a paper survey. Design and Sample: Psychometric study. Participants were 277 expectant mothers (n = 161) and fathers (n = 106) enrolled in Childbirth Essentials, a 6‐week prenatal education program. Measures: The UpStart Parent Survey – Prenatal is a retrospective pretest/posttest survey with three scales: Parenting Knowledge, Parenting Experience, and Program Satisfaction, and three open‐ended questions. Results: The UpStart Parent Survey – Prenatal is sensitive to change and demonstrated significant positive differences in parenting knowledge and parenting experience. There was no difference in results whether the survey was completed by mothers or fathers. Results were similar whether paper or electronic formats were used. The survey was easy to complete. Conclusion: The UpStart Parent Survey – Prenatal holds promise as a reliable and valid evaluation tool to capture outcomes of brief prenatal education programs that target the general population of expectant parents.

The use of Global Navigation Satellite System (GNSS) in combination with real-time kinematic technique, known as differential GNSS (dGNSS), has increased in recent years for monitoring landslide displacements and detecting early signs of potential failure, enabling an earlier response for risk mitigation than traditional monitoring techniques. GNSS offers several advantages, including high accuracy and high-frequency data collection. Although more cost-effective, their affordability may still present challenges for public organizations managing multiple landslides in their territory. The SparkFun is a suite of components for GNSS assembly designed for topographic surveying, that integrates u-blox ZED-F9P or ZED-F9R modules. The system offers the benefits of dGNSS technology while being more affordable than other market options. It also avoids relying on phone signals for data storage on a cloud server. This paper presents the SparkFun system, its components, and how it can be assembled to create a dGNSS system for landslide monitoring. The deployment and testing at the Chin Coulee landslide in Alberta are discussed. Over the 6-month testing period, the system achieved millimeter accuracy (up to 14 mm), aligning with the manufacturer's specifications. Estimated system errors were found to be comparable to a commercially available dGNSS system (Ophelia Geocube). Additionally, the system exhibits displacement trends similar to the 2018 Geocube monitoring campaign; however, for future deployments, the robustness of the power supply system and the insulation of the equipment need to be enhanced. Overall, the SparkFun system appears to be a promising and cost-effective alternative for monitoring landslide displacements. [ABSTRACT FROM AUTHOR]

The purpose of the paper was to draw lessons for the field of adapted physical activity from the interrelated literatures on interdisciplinarity, creativity, and team research. In each of these literatures, strategies have been identified that have been found to be useful by previous researchers. Lack of familiarity with these strategies can result in unsuccessful research projects or in the devotion of scarce resources to the reinvention of such strategies. The first section in the paper in particular addresses questions that arose at the 2016 North American Federation of Adapted Physical Activity symposium in Edmonton, Alberta. [ABSTRACT FROM AUTHOR]

Background: Inflammatory bowel diseases (IBDs) are chronic gastrointestinal diseases that negatively affect the enjoyment of food and engagement in social and cultural gatherings. Such experiences may promote psychosocial challenges, an aspect of IBD often overlooked and under‐supported in clinical settings and research. Objectives: This study explored the psychosocial experiences that young adults with IBD have with food via a qualitative patient‐led research process. Methods: Trained patient researchers conducted this study by engaging peers via semi‐structured interviews and focus groups in a three‐step co‐design process. Participants (n = 9) identified the research topic (SET), explored the topic and identified emerging themes (COLLECT), refined themes and made recommendations for healthcare system change (REFLECT). Results: Themes that emerged included: 'Experimenting with Food', 'Evolution Over Time', 'Diet Changes are Emotional' and 'Role of Stigma'. Participants identified the significance and frustrations of repeated testing and experimenting with food compatibility, and noted nuances in food relationships as they gain knowledge and experience over time. They emphasized the importance of maintaining a sense of hope throughout and wished to impart this to newly diagnosed patients. Conclusion: Participants experience numerous psychosocial challenges as they strive to manage their diet, noting gaps in support available from IBD practitioners. Participants made practical recommendations for healthcare system change to improve patient outcomes, highlighting the importance of sharing stories and collaboratively including patients in the development of new services and protocols. Authors recommend further research in this area to build a body of knowledge and support that helps IBD patients maintain hope while navigating challenges with food. Patient or Public Contribution: The first four authors on this paper were the lead researchers in this study's design and analysis and identify as patients; they conducted the research with this identity at the forefront following a peer‐to‐peer research model. These authors were mentored by patient researchers who also contributed to the manuscript, and the research process itself was co‐lead and directed by other patient participants and consultants. Results and recommendations coming from this paper came directly from patient participants. [ABSTRACT FROM AUTHOR]

Purpose: The bid/no-bid decision is critical to the success of construction contractors. The factors affecting the bid/no-bid decision are either qualitative or quantitative. Previous studies on modeling the bidding decision have not extensively focused on distinguishing qualitative and quantitative factors. Thus, the purpose of this paper is to improve the bidding decision in construction projects by developing tools that consider both qualitative and quantitative factors affecting the bidding decision. Design/methodology/approach: This study proposes a mixed qualitative-quantitative approach to deal with both qualitative and quantitative factors. The mixed qualitative-quantitative approach is developed by combining a rule-based expert system and fuzzy-based expert system. The rule-based expert system is used to evaluate the project based on qualitative factors and the fuzzy expert system is used to evaluate the project based on the quantitative factors in order to reach the comprehensive bid/no-bid decision. Findings: Three real bidding projects are used to investigate the applicability and functionality of the proposed mixed approach and are tested with experts of a construction company in Alberta, Canada. The results demonstrate that the mixed approach provides a more reliable, accurate and practical tool that can assist decision-makers involved in the bid/no-bid decision. Originality/value: This study contributes theoretically to the body of knowledge by (1) proposing a novel approach capable of modeling all types of factors (either qualitative or quantitative) affecting the bidding decision, and (2) providing means to acquire, store and reuse expert knowledge. Practical contribution of this paper is to provide decision-makers with a comprehensive model that mimics the decision-making process and stores experts' knowledge in the form of rules. Therefore, the model reduces the administrative burden on the decision-makers, saves time and effort and reduces bias and human errors during the bidding process. [ABSTRACT FROM AUTHOR]

• Wood ash from Alberta's pulp and paper industry is used in lieu of Portland cement. • Cement-based foams are cast to achieve density ranging from 1000 to 1400 kg/m3. • Mechanical, thermal and acoustic properties are examined here. • Wood ash lowers thermal conductivity and noise, with minor drop in strength. • For indoor insulation, wood ash may replace cement at 10% for optimal effect. This study characterizes a Portland cement based cellular system prepared with a preformed foam. Wood ash, locally sourced from pulp and paper mills, was first characterized and later, blended at up to 20% of the binder. The resulting mixtures were cast at three densities between 1000 and 1400 kg/m3 and examined for mechanical, thermal and acoustic properties. A phase analysis was performed using X-ray diffraction to identify the components of the wood ash and again, in the hydrated system. The thermal constants were measured using the Transient Plane Heat Source (TPS) technique per ISO 22007-2. Sound absorption and noise reduction coefficients were evaluated using the impedance tube method per ASTM C384-04. The results show that although blending wood ash led to lower compressive strength and elastic modulus, the drop in strength was within 20%. While not as effective in reducing noise, the wood ash led to 20% lower thermal conductivity. These findings offer wood ash as a viable, replenishable and sustainable substitute for Portland cement in insulating foams. [ABSTRACT FROM AUTHOR]

Two years ago, the Alberta government put in place a temporary oil-production quota. However, the quota's impact could well be felt in the province's oil production for years to come. The quota applied only to firms producing more than 10,000 barrels of oil per day and was instituted as a response to pipeline constraints that caused Alberta oil prices to be much lower than prices elsewhere. Production from both oilsands mines and oil wells dropped as soon as the government announced the quotas. The media warned that the quotas would force production to transfer to Saskatchewan, but the research for this paper found that this never occurred. The quota policy was announced in December 2018 and a week later, the price of Alberta oil had jumped from $29.09/bbl to $50.08 bbl, a 72 per cent rise. When the quota policy actually took effect the first of January 2019, the price increased again, but by much less. The anticipation of the quota alone was enough to create the desired price increase. The quota, which set limits for the total combined crude oil and bitumen permitted to be produced, was assigned to individual operators and designed to provide an 8.5 per cent reduction in oil production. The total quota was fixed at 3.56 million barrels a day in January 2019, but individual quotas could be traded across eligible operators, minimizing the overall costs of achieving the total goal. However, total production continued falling even when the quota was eventually relaxed; the market and a low world price created a scenario in which production fell below the amount permitted by the quota. All the oil companies reduced their production regardless of whether they fell within the quota's guidelines or not; however, the firms that were subject to the quota reduced their production more than the others. The quota was lifted in December 2020 when export capacity again became sufficient. While curtailing production had the desired result of raising Alberta oil prices and resolving the differential between local prices and the world benchmark, its ripple effects may well be felt in the longer term. This paper finds that fewer wells are being drilled and more wells are suspending production. Tradition dictates that when a well becomes inactive, it is rarely returned to a productive state. Those firms that resorted to low levels of drilling in order to meet the quota have created a situation that could affect Alberta oil production in the years ahead. [ABSTRACT FROM AUTHOR]

This paper further explores the findings of a 2020 case study focused on the perspectives of parents of children aged 5–9 years old attending elementary schools in French language programs during the 2020 school closure and the potential legacy of the Coronavirus pandemic on education. In March 2020, the school learning of elementary school children in different school boards in Alberta moved to a novelty style of temporary 'homeschooling' format through virtual learning aided by parental support. Parents played an essential role during this learning process; ten parents shared their experiences in this study. Such experiences may be key to integrating more effective teaching and virtual learning practices and pinpointing potential shortcomings as students return to in-person learning. This paper focuses on three main aspects of coronavirus-induced 'homeschooling': The role of parental support, parents' perspectives of how young children learn in virtual learning environments, and pedagogical practices from curriculum design to implementation of differentiated learning practices. The study is significant as it may contribute to further understanding of how young children learn in virtual settings, the effectiveness of current educational practices, and the problematic legacy of the coronavirus for the future of education.

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.

This paper overviews our recent results of energy market modeling, including The option pricing formula for a mean-reversion asset, variance and volatility swaps on energy markets, applications of weather derivatives on energy markets, pricing crude oil options using the Lévy processes, energy contracts modeling with delayed and jumped volatilities, applications of mean-reverting processes on Alberta energy markets, and alternatives to the Black-76 model for options valuation of futures contracts. We will also consider the clean renewable energy prospective in Canada, and, in particular, in Alberta and Calgary. [ABSTRACT FROM AUTHOR]

The opioid overdose crisis in Canada continues to claim the lives of people who use drugs (PWUD). Historically, Canadian crime policy has prioritized crime control forms of surveillance, interdiction and punishment in response to drug use. More recently, harm reduction measures have gained traction, including safe consumption sites (SCS) and police officer use of Naloxone to assist PWUD who have overdosed on opioids. The effectiveness of harm reduction efforts, however, is to some degree contingent on their embrace or acceptance by police agencies and officers. This paper is based on research conducted on the two largest city-level police services in Alberta, Canada. We conducted 94 interviews with officers and had 1,406 officers complete a quantitative survey on issues relating to illicit drugs, overdoses, and fentanyl. Our findings show that police officers generally see opioid use as a serious problem and are concerned about the dangers they face when dealing with PWUD. There is also considerable confusion about the nature and severity of these dangers. Even so, attitudes appear to be shifting and some police officers are changing their practices. In general, our research documents a softening of police attitudes in Canada towards SCS facilities and harm reduction more generally. This greater embrace of a public health orientation could improve the lives of PWUD and their interaction with law-enforcement in Canada. Given the prospect that fentanyl and related synthetic opioids will continue their global spread, these findings should be of interest to an international audience of scholars, police, and healthcare officials.

Assessing the reliability and resiliency of transportation infrastructure is critical to improving the safety and sustainability of roadways. Such information, particularly when available on a network level helps transportation agencies identify vulnerable locations on their road network and make more informed decisions when managing infrastructure and when introducing design improvements. To that end, many design experts have promoted integrating the risk of failure of roadway design elements to satisfy road user demand (i.e., reliability measures) into the highway design process. In fact, previous work has established a link between design reliability and safety. Although exploring such relationships provides extremely valuable insights on the impacts of meeting or deviating from design requirements, it does not provide much information on where the most (and least) reliable road segments exist on a network. To overcome these critical shortcomings, this paper proposes the adoption of hot spot analysis and spatial interpolation to assess reliability of compliance with sight distance requirements on an aggregate network level. Light Detection and Ranging (LiDAR) data was first used to quantify available sight distance on 220 curved segments, and design reliability to sight distance requirements was then assessed at each location. Hot spot analysis and spatial interpolation using the inverse distance weighting method were then employed to identify regions of the Alberta road network where low or high design reliability existed or could be expected. The analysis revealed that the highest-risk regions on the Alberta highway network existed in areas of mountainous in the western region of the province as well as areas of rolling terrain in south Calgary. In contrast, it was found that curved road segments in the prairie region had a significantly higher design reliability to sight distance. The clustering of unreliable roadway segments in mountainous regions and regions of rolling terrain indicates that more effort is required to improve design reliability in those regions. Such important inferences are only possible when conducting an aggregate reliability assessment such as the one proposed in this paper. [ABSTRACT FROM AUTHOR]
