This document is a comment on a previous article discussing the regulatory design of the Water Sustainability Act (WSA) in British Columbia, Canada. The comment argues that the WSA's regulatory design took a science-forward approach and considered specific regional factors. It addresses criticisms of the WSA and emphasizes the importance of licensing groundwater use for assessing environmental impacts. The WSA allows for nuanced water management through regulation-making authorities, but challenges remain in implementing the regulations, including Indigenous water rights and government resources. Recommendations for improving the WSA's design include defining sustainability goals, regionalizing regulatory action, and long-term planning. Ongoing resourcing and consideration of Indigenous rights are necessary for the effective implementation of the WSA. [Extracted from the article]

Predatory publishing is the unethical and dishonest behavior of publishers who take advantage of researchers by charging them too much money and not providing good editing and peer-review services. Scholars, publishers and policymakers are seeking solutions to combat predatory publishing, which has become a major academic problem. This research paper provides a bibliometric analysis of the citation patterns and trends in the predatory publishing literature. The study analyzed the 100 top-cited papers on predatory publishing and provided insight into the types of documents, journals, authors, and countries that contributed to this field. The average citation per paper in the top 100 selected publications was 53.67. Open-access publications received a significantly higher average citation per paper than subscription-based papers. "Article" was the major type of document published, followed by "Notes," "Reviews" and "Editorials." Nature and Learned Publishing were the journals that contained the highest number of top-cited articles. J. Beall and D. Moher authored the highest number of papers, while A. Grudniewicz had the highest average citation per paper. USA and Canada were the top countries in these top-cited publications. This study will be beneficial to the all the stakeholders who may be interested in this area of research. [ABSTRACT FROM AUTHOR]

Combined paper mill biosolids (PB) and forest-derived liming by-products improve soil properties, but their residual effects following several years of application have hardly been investigated. A 13-year (2009–2021) field study was initiated at Yamachiche, QC, Canada, to assess the residual effects of PB and liming materials on the properties of a loamy soil. The PB was applied during nine consecutive years (2000–2008) at 0, 30, 60, and 90 Mg wet·ha−1, whereas the 30 Mg PB·ha−1 rate also received one of three liming materials (calcitic lime, lime mud, wood ash) at 3 Mg wet·ha−1. No amendment was applied during residual years. Past liming materials continued to increase soil pH but their effect decreased over time; meanwhile, past PB applications caused a low increase in residual soil NO3-N. Soil total C, which represented 40% of added organic C when PB applications ceased, stabilized to 15% after six years. Soil Mehlich-3-extractable contents declined over the thirteen residual years to be not significant for P, K, and Cu, while they reached half the values of the application years for Zn and Cd. Conversely, Mehlich-3 Ca was little affected by time. Therefore, land PB and liming material applications benefited soil properties several years after their cessation. [ABSTRACT FROM AUTHOR]

Introduction: Osteoporosis is a major disease state associated with significant morbidity, mortality, and health care costs. Less than half of the individuals sustaining a low energy hip fracture are diagnosed and treated for the underlying osteoporosis. Objective: A multidisciplinary Canadian hip fracture working group has developed practical recommendations to meet Canadian quality indicators in post hip fracture care. Methods: A comprehensive narrative review was conducted to identify and synthesize key articles on post hip fracture orthogeriatric care for each of the individual sections and develop recommendations. These recommendations are based on the best evidence available today. Conclusion: Recommendations are anticipated to reduce recurrent fractures, improve mobility and healthcare outcomes post hip fracture, and reduce healthcare costs. Key messages to enhance postoperative care are also provided. [ABSTRACT FROM AUTHOR]

With Canada becoming the first G20 country to legalize the recreational use of cannabis, there has been increasing interest in the emergence of this new marketplace. Newspaper framing helps to shape public opinion on legalization and news sources play a role in determining how the public perceives the use of cannabis. This research analyzes how mainstream newspapers reported on the legalization of recreational cannabis in Canada in the years before and after legalization (between 2016 and 2019). Using a content analysis of 1,390 cannabis-related articles, 11 dominant reporting themes are identified. Over time, there was a shift from negative and sensationalist cannabis news coverage toward more balanced and progressive framing. The findings identify the influence of editorial political stance on thematic coverage. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. In 2011, the Canadian Academy of Sport and Exercise Medicine released their first position paper on Abuse, Harassment, and Bullying in Sport. Since this time, there have been significant advancements within the global sport landscape, including the emergence of regulatory bodies and initiatives aimed at prioritizing athletes' health and well-being. While the shift to a more proactive approach for safeguarding athletes is evident and promising, athletes continue to be affected by cases of maltreatment. To advance safe sport, it is critical that all supporters of safe and healthy performance are aware of their roles and responsibilities for preventing and addressing maltreatment, including the Canadian sport medicine community. In this updated position statement, recent advancements in research on issues of maltreatment are summarized and specific recommendations are provided on how the medical community can contribute to appropriately identifying, treating, and preventing harm in sport, as well as their role in advocating for the health and well-being of athletes in their care.

Prostate cancer is the most common malignancy and the third most common cause of death in Canadian men. In light of evolving diagnostic pathways for prostate cancer and the increased use of MRI, which now includes its use in men prior to biopsy, the Canadian Association of Radiologists established a Prostate MRI Working Group to produce a white paper to provide recommendations on establishing and maintaining a Prostate MRI Programme in the context of the Canadian healthcare system. The recommendations, which are based on available scientific evidence and/or expert consensus, are intended to maintain quality in image acquisition, interpretation, reporting and targeted biopsy to ensure optimal patient care. The paper covers technique, reporting, quality assurance and targeted biopsy considerations and includes appendices detailing suggested reporting templates, quality assessment tools and sample image acquisition protocols relevant to the Canadian healthcare context.

Introduction: Drug checking services for harm reduction and overdose prevention have been implemented in many jurisdictions as a public health intervention in response to the opioid overdose crisis. This study demonstrates the first on‐site use of paper spray mass spectrometry for quantitative drug checking to address the limitations of current on‐site drug testing technologies. Methods: Paper spray mass spectrometry was used to provide on‐site drug checking services at a supervised consumption site in the Downtown Eastside of Vancouver, British Columbia, Canada during a 2‐day pilot test in August 2019. The method included the targeted quantitative measurement of 49 drugs and an untargeted full scan to assist in identifying unknown/unexpected components. Results: During the pilot, 113 samples were submitted for analysis, with 88 (78%) containing the client expected substance. Fentanyl was detected in 45 of 59 expected fentanyl samples, and in 50 (44%) samples overall at a median concentration of 3.6% (w/w%). The synthetic precursor of fentanyl, 4‐anilino‐N‐phenethyl‐piperidine (4‐ANPP), was found in 74.0% of all fentanyl samples at a median concentration of 2.2%, suggesting widespread poor manufacturing practices. Etizolam was detected in 10 submitted samples anticipated to be fentanyl at a median concentration of 2.5%. No clients submitting these samples expected etizolam or a benzodiazepine in their sample. In three instances, it was co‐measured with fentanyl, and in seven cases it was detected alone. Discussion and Conclusions: The quantitative capabilities and low detection limits demonstrated by paper spray mass spectrometry offer distinct benefits over existing on‐site drug checking methods and harm reduction services.

• 72% − 80% of fibre was recovered from disposable coffee cups. • 2% and 3% consistency shredded cups required > 100 kWh/tonne to repulp with 3 refiner passes. • Pulp quality did not significantly diminish after repulping using a single-disk refiner. Over 64 billion paper-plastic laminate (PPL) coffee cups are consumed between the United States and Canada annually, the majority accumulating in landfills due to a hydrophobic plastic inner-lining. Recycling can mitigate environmental damage and provide economic value from repurposed products. We found that standard repulping methods were insufficient to separate fiber from plastic due to the low intensity of treatment. To increase process intensity, we mechanically refined shredded PPL coffee cups and Kraft eucalyptus sheets (control) at 2%, 3%, and 4% consistencies with three passes to determine the energy required to separate fibers from plastic and the effects on fiber quality. 2% and 3% consistency PPL cups measured under 40 kWh/tonne of input material for one refiner pass and ∼ 80 kWh/tonne for 4% consistency PPL cups. Recovered fiber fraction totaled 87.7%, 85.3%, and 80.5% of input mass of Kraft eucalyptus and 72.3%, 72.6%, and 79.6% of input mass of PPL cups at 2%, 3%, and 4% consistency, respectively. Fines content of PPL cups jumped from 8% pre-refining to ∼ 30% post-refining while Kraft eucalyptus fibers were unaffected, suggesting that breaking the plastic-fiber bonds results in fines generation. Mean fiber length of PPL cups slightly decreased with consistency and tensile strength improved. Freeness decreased with consistency only in PPL cup samples. These results demonstrate a low energy requirement to effectively separate fiber and plastics in PPL cups as well as minimal impact on fiber quality using existing refining technology, and provides an estimate of the financial costs of local recycling efforts.

This paper investigates the role of admission forms in the regulation of asylum confinement in the second half of the nineteenth century. Taking the Toronto Lunatic Asylum as a case study it traces the evolution of the forms' content and structure during the first decades of this institution. Admission forms provide important material for understanding the medico-legal assessment of lunacy in a certain jurisdiction. First, they show how the description of insanity depended on a plurality of actors. Second, doctors were not necessarily required to indicate symptoms of derangement. Third, patients' relatives played a fundamental role in providing clinical information. From an historiographical perspective, this paper invites scholars to consider the function of standardized documents in shaping the written identity of patients. [ABSTRACT FROM AUTHOR]

This paper will examine how extremist organizations manage to present themselves as credible actors in the eyes of potential supporters on social media. This paper will address this question by exploring the role of authenticity in strategic narratives, which is believed to help these groups achieve this purpose. Apart from introducing this new theoretical concept, the paper will also apply it to a new case study of the Russian Imperial Movement (RIM) – the first far-right organization to be designated as terrorist by the U.S. and Canada. By conducting discourse analysis of the group's social media propaganda on the Russian network VKontakte, the paper will show how the RIM makes its strategic narratives authentic and, as a consequence, creates an image of a credible and trustworthy actor and thus manages to reach out to its target audience.

Methods: The study is based on 45,368 global publications, sourced from the Scopus bibliographical database, covering three decades (1994–2023). We studied the performance of the top 12 developed and top 12 developing countries. The key countries, organizations and authors at national and international levels were identified. The broad subject areas and key journals contributing to global OA research were delineated, besides identifying the broad characteristics of highly cited papers in the field. Results: The United States and China were the most productive countries, while the Netherlands and Canada made the largest citation impact. Harvard Medical School and the University of Sydney made the most contribution, while Boston University and Pfizer Inc., USA registered the highest citation impact. Hunter DJ and Guermazi A were the most productive authors, while Lohmander LS, and Hochberg MC registered the highest citation impact. Osteoarthritis and Cartilage (n = 4879) and Annals of the Rheumatic Diseases (n = 786) published the maximum papers, while Arthritis and Rheumatism and Nature Reviews Rheumatology registered the largest citation impact. The highly cited papers with 100 or more citations constituted 6.25% of the total publications. Conclusions: There has been a systematic growth of publications on OA. The research on OA was mainly done in developed countries, with the maximum publications coming from the United States of America, China and Canada. The most impactful publications on OA were from the Netherlands, Canada and the United States of America. [ABSTRACT FROM AUTHOR]

Background: In 2016–17 an important consensus was established regarding the use of the diagnostic label 'developmental language disorder' (DLD) to describe children with a persistent language problem having a functional impact on communication or learning and in the absence of any other biomedical condition. Despite this consensus, past research has revealed ongoing uncertainty regarding when to use the DLD label among speech–language pathologists (SLPs). Aims: In response to this uncertainty, a survey of SLPs was conducted aimed at investigating which types of clinical language profiles, and specific assessment results, were viewed as warranting the diagnostic label DLD. Methods & Procedures: SLPs were presented with 10 childhood language profiles and assessment results. Participants reviewed each case and described if they felt a diagnosis of DLD was warranted, which presented symptoms were consistent/inconsistent with DLD and if further information/testing was desired. Additionally, participants provided details regarding their personal diagnostic processes. Outcomes & Results: Results indicated a general consensus among SLPs as to when the DLD label should be applied. However, free‐text responses demonstrated considerable variation between clinicians regarding symptoms of importance, points of contention/confusion in language profiles and minimal assessment results viewed as necessary in the diagnostic process. Conclusions & Implications: This detailed look at the assessment/diagnostic process for DLD provides valuable insight into how to build further practice consistency in the provision of the diagnostic label DLD, especially in cases of complex language profiles and assessment results. WHAT THIS PAPER ADDS: What is already known on this subject: The label DLD should be used as a diagnostic label to describe children with persistent language problems having a functional impact on communication or learning and in the absence of any biomedical condition. However, in current clinical practice, actual use of the label is inconsistent and SLPs face a number of challenges in diagnosing DLD. What this paper adds to the existing knowledge: This investigation provides clarity regarding which complexities in paediatric language profiles are most challenging for SLPs when determining if a child does/does not have DLD. Additionally, details regarding current assessment beliefs and practices are explored. What are the practical and clinical implications of this work?: By providing a detailed look at the diagnostic processes of practising SLPs, valuable insight is provided into how to build further practice consistency and confidence in the provision of the diagnostic label DLD, especially in cases of complex language profiles and assessment results.

Through an examination of the history of settler colonial violence against Indigenous peoples and lands in Canada, Palestine, and Australia, this paper exposes the links between colonialism and the penitentiary, across borders. This paper interrogates the differences and similarities between the use of prisons as a tool in settler colonial expansion in these three states. As a contribution to abolitionist thought and theory, this paper highlights the need for an intersectional analysis of the overlapping consequences of settler colonialism and international carceral regimes. Efforts to resist carceral expansion around the world must include efforts to resist colonial expansion, and the voices of Indigenous peoples must be centred throughout this process.

A complex dynamical network (CDN) can be considered as the composition system with the nodes subsystem (NS) and the links subsystem (LS), and both subsystems are coupled with each other. In this paper, two vector differential equations (VDE) are used to describe the dynamical behaviours of NS and LS, respectively, in which the dynamical behaviour of NS is considered as the VDE with the second derivative term (SDT). This paper mainly focuses on the dynamics of LS, which is represented as VDE with the intuitive topologic feature of outgoing links, and investigates the design of the tracking controller for NS and the auxiliary tracking objectives (ATO) for LS. Firstly, the dynamical models of NS and LS in CDN are proposed, and the corresponding assumptions are given. Secondly, based on Lyapunov stability theory, the controller of NS and the ATO of LS are designed so that the state of NS can asymptotically track the given reference signal. Finally, the effectiveness of the proposed control strategy in this paper is verified by the numerical simulation example with N two-links robots.

In pediatric settings, the concept of hope is frequently positioned as a fundamental aspect of care and at odds with the possibility and proximity of death. This arguably fosters silence about death and dying in childhood despite evidence indicating the benefits of open communication at the end of life. In this paper, we describe the unspeakable nature of death and dying in childhood, including its conceptual and clinical causes and dimensions, its persistence, and the associated challenges for children and youth facing critical illnesses, their families, and society. We explore how the tension between hope and death can be reframed and apply our analysis to the context of medical assistance in dying for mature minors in Canada. Considering the lack of related literature, this paper offers initial reflections to form a framework for the unspeakable nature of death and dying in childhood and to advance the crucial need for research.

Despite the emerging body of literature on the benefits of youth peer support, there is also evidence that peer support can have unintended negative impacts on peers themselves. It is important to explore what aspects of the peer role contribute to these difficulties in order to mitigate risks. This paper uses a participatory approach to examine the unique attributes of youth peer practice and the related challenges. We conducted semi-structured interviews and focus groups with both peer and non-peer staff from a community-based youth mental health program that provides peer support services (N = 29). Thematic analyses were completed using QSR NVivo. Analyses capture the defining features and related challenges of the peer support role (self-disclosure, boundaries, role confusion and dynamic recovery), and risk factors that affect peers (stigma, exposure to harm and burnout). This paper contributes to the literature on peer support as well as youth participatory evaluation. The findings will be useful to support the development of improved organizational contexts for peer practice and more effective peer support programming. [ABSTRACT FROM AUTHOR]

Addressing sexting in sexual health education classrooms is one way of supporting young people to become good sexual citizens and to emphasise respect and consent in their sexual practices and in their lives. While a fair amount of research has worked with youth to understand their motivations for sexting, less research has been conducted with in-service teachers to understand their perspectives, pedagogical approaches, and beliefs regarding young people and sexting. Set in this context, this paper discusses findings from interviews with Canadian teachers who were teaching a new Ontario Health and Physical Education curriculum that included discussions of sexting. Our findings suggest that many teachers are still engaging discourses of risk, shame and blame when they talk to their students about sexting. Likewise, longstanding gender norms and stereotypical sexual scripts are evident in the ways in which many teachers both understand and teach sexting. Some teachers, however, are engaging in more promising pedagogical practices that frame sexting as having a range of uses, outcomes, and purposes, painting a more holistic picture of young people's sexting landscapes. Findings from this paper may be useful for educators and policymakers creating sexting curriculum for young people in educational settings. [ABSTRACT FROM AUTHOR]

Background: The impact of the COVID-19 pandemic on young people with eating disorders (EDs) and their families was profound, with surging rates of hospitalizations and referrals reported internationally. This paper provides an account of the additional health and social costs of ED care for young people living in Canada incurred during the COVID-19 pandemic, drawing attention to the available data to inform these estimates while noting gaps in data capacities to account for a full view of the ED system of care. Methods: Three methodologies were used to capture costs: (1) provincial administrative data holdings available at the Canadian Institute of Health Information (CIHI) were used by Deloitte Access Economics to conduct analyses on costs related to hospitalizations, emergency room visits, outpatient visits with physicians and loss of well-being from being on a waitlist. These were examined across three fiscal years (April 1 to March 31, 2019–2022) to compare costs from one year before to two years after the onset of the pandemic, (2) data collected on support-based community ED organizations and, (3) costs identified by young people, caregivers and health care professionals. Results: Estimates of additional health care costs and social costs arising from ED care waitlists were estimated to have increased by 21% across the two years after the onset of the pandemic and is likely to represent an underestimate of costs. Costs related to some standard ED care services (e.g. day treatment programs) and support-based community ED organizations that saw a 118% increase in services during this time, are some examples of costs not captured in the current cost estimate. Conclusions: This paper provides a first account of the additional health and social ED care costs associated with the pandemic, which indicate at minimum, a 21% increase. The results invite discussion for more investments in ED services for young people in Canada, as it is unclear if needs are expected to remain elevated. We suggest a call for a national surveillance strategy to improve data holdings to aid in managing services and informing policy. A robust strategy could open the door for much-needed, data-informed, system transformation efforts that can improve ED care for youth, families and clinicians. [ABSTRACT FROM AUTHOR]

This paper contributes to international feminist debates on shared parenting and family violence via reforms to Canada's Divorce Act, in force since 2021. Looking backwards, it reviews parliamentary debates and early judicial discussions. The documentary review reads the reforms as an unstable compromise between calls from feminist voices and experts on family violence and from groups representing fathers. Family violence is now defined broadly and declared relevant to children's welfare. But language in the statute may undermine its seriousness. Exposing the tensions underlying these reforms is useful for Canadian participants in family justice and for scholars, practitioners, and policymakers elsewhere, exemplifying the promise and perils of reform in this area. Looking ahead, the paper offers recommendations to higher courts. Appellate judges should read rules on contact with both parents and parental cooperation in the light of the new recognition of family violence, taking the latter as an overarching objective of the statute.

Agricultural injuries remain a major concern in North America, with a fatal injury rate of 19.5 deaths per 100,000 workers in the United States. Numerous research efforts have sought to compile and analyze records of agricultural-related injuries and fatalities at a national level, utilizing resources, ranging from newspaper clippings and hospital records to Emergency Medical System (EMS) data, death certifications, surveys, and other multiple sources. Despite these extensive efforts, a comprehensive understanding of injury trends over extended time periods and across diverse types of data sources remains elusive, primarily due to the duration of data collection and the focus on specific subsets. This systematic review, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, consolidates and analyzes agricultural injury surveillance data from 48 eligible papers published between 1985 and 2022 to offer a holistic understanding of trends and challenges. These papers, reporting an average of 25,000 injuries each, were analyzed by database source type, injury severity, nature of injury, body part, source of injury, event/exposure, and age. One key finding is that the top source of injury or event/exposure depends on the chosen surveillance system and injury severity, underscoring the need of diverse data sources for a nuanced understanding of agricultural injuries. This study provides policymakers, researchers, and practitioners with crucial insights to bolster the development and analysis of surveillance systems in agricultural safety. The overarching aim is to address the pressing issue of agricultural injuries, contributing to a safer work environment and ultimately enhancing the overall well-being of individuals engaged in agriculture.

The availability of high-quality aggregate for infrastructure development in Canada has significantly decreased. This reduction has posed significant challenges, particularly in large urban areas across Canada. Moreover, exploring the potential of incorporating innovative by-products into pavement structures has displayed potential advantages in technical, economic, and environmental aspects. The methodology presented in this paper is based on several research projects from over the past twenty years. This case study is based on the several research projects that have been conducted at the Centre for Pavement and Transportation Technology (CPATT) in Canada. The focus of this paper is developing a framework that can be used to evaluate the use of recycled materials in asphalt pavement. These include recycled concrete aggregate (RCA); recycled asphalt roof shingles (RAS); recycled crumb rubber (RCR); and recycled asphalt roof shingles (RAS) in asphalt pavement. In addition, the use of RCA in concrete pavement will also be evaluated. In addition, the use of RCA in concrete pavement will also be evaluated. A methodology and strategy for implementing these materials and designs into specifications, while also managing risk, are outlined. Finally, the work presents a life cycle assessment analysis, including the analysis of cost and sustainability. Overall, the paper illustrates the process of evaluating products, technologies, and designs from technical, economic, and environmental viewpoints, and then implementing them in a robustly engineered way. Generally, the collected data results from the lab, field performance of the test sites, and sustainability and Life Cycle Cost Assessment (LCCA) analyses are very promising. For example, the Hot Mix Asphalt (HMA) pavement design with a 40% RAP was the most environmentally friendly. Meanwhile, it was determined that the HMA mix comprising 20% RAP and 20% Crumb Rubber Modifier (CRM) was found to be the most creative and environmentally friendly option. According to another study, higher storage durations were shown to improve RAP and virgin binders' blending, thereby raising the general quality of HMA and RAP mixtures. Furthermore, the study discovered that mixtures containing various types of untreated CRCA in different amounts had higher Indirect Tensile Strength (ITS), rutting resistance, and stiffness modulus than the control mix, which contained 0% coarse recycled concrete aggregate (CRCA). This suggests that the effective utilization of recycled materials is a viable approach with the capacity to significantly enhance the adoption of recycled components in asphalt pavements.

Healthcare systems and health professionals are facing a litany of stressors that have been compounded by the pandemic, and consequently, this has further perpetuated suboptimal mental health and burnout in nursing. The purpose of this paper is to report select findings from a larger, national study exploring gendered experiences of mental health, leave of absence (LOA), and return to work from the perspectives of nurses and key stakeholders. Given the breadth of the data, this paper will focus exclusively on the qualitative results from 53 frontline Canadian nurses who were purposively recruited for their workplace insight. This paper focuses on the substantive theme of "Breaking Point," in which nurses articulated a multiplicity of stress points at the individual, organizational, and societal levels that amplified burnout and accelerated mental health LOA from the workplace. These findings exemplify the complexities that underlie nurses' mental health and burnout and highlight the urgent need for multipronged individual, organizational, and structural interventions. Robust and timely interventions are needed to restore the health of the nursing profession and sustain its future. [ABSTRACT FROM AUTHOR]

The lack of yield response to the N-fertilizer strategies highlights the importanceproper timing of N-fertilizer application for potatoes which will allow reduction of N-fertilizer rate without compromising tuber yield. Two potato cultivars (Vigor and Lady Claire) were used in this study and potato tubers were collected from a potato farm in Alberta, Canada. A thorough understanding of such changes is required to optimize quality and yield potential.. A study consisting of five contrasting potato cultivars was undertaken to investigate the physiological and biochemical response of potato cultivars to N rate in terms of tuber dry matter accumulation, partitioning and quality. One method for reducing N loss to the environment is growing potatoes that require less added N. Identifying Nitrogen Use Efficient (NUE) potato varieties and characterizing their response to N stress are necessary steps to breeding for NUE in potato. Three potato-based cropping sequences, wheat-potato-wheat, canola-potato-wheat, and fababean-potato-wheat were evaluated under irrigation at the Canada-Manitoba Crop Diversification Centre at Carberry, Manitoba, Canada.

[Display omitted] • Novel method to estimate total technical potential for improving energy efficiency. • Bottom-up sector energy model used to characterize energy demands and opportunities. • Technology-explicit analysis framework used to estimate integrated energy savings. • Application to Canada's pulp & paper sector indicates major savings are possible. • Technical potential to reduce natural gas use by 95% and net electricity by 54% Industrial energy efficiency has long been recognized as a critical tool for energy management and emissions reduction and is increasingly considered to be an energy resource in its own right. However, the complexity of most industrial sectors creates barriers for modellers, companies, and policymakers in understanding and achieving the overall potential for efficiency-driven energy savings. To address this gap, we have developed a novel method that combines disaggregated bottom-up sector energy modelling with analysis of a comprehensive set of technology-explicit energy efficiency measures. This approach overcomes the deficiencies of top-down analyses and better represents the complexities of multi-measure efficiency investments compared to piecewise studies of individual measures. In this study, we demonstrated application of our method to the case of the Canadian pulp and paper sector. Our analysis shows that the sector can reduce its natural gas and electricity use by 95% and 41%, respectively, by adopting economical efficiency measures. This equates to 71 PJ of natural gas and 44 PJ of electricity saved annually and would result in cost savings of $81 per tonne of output sector-wide. Notably, we find that efficiency and fuel switching have the technical potential to reduce natural gas consumption by 98% across the sector. Taken together, the results provide quantitative evidence that energy efficiency is an underestimated resource for cost-effective energy savings in the Canadian pulp and paper sector. Our analysis framework can be applied to any industrial sector in any region to provide insights regarding energy conservation strategies and policy design. [ABSTRACT FROM AUTHOR]

Social scientists, geographers, criminologists, and health scientists are often tasked with finding data to best capture the impact of "community context" on individual outcomes, including residential services, physical resources, and social institutions. One outlet for such data in Canada is Digital Map Technologies Inc. (DMTI) Spatial, which offers a national repository of over one million businesses and recreational points of interest. The database is generated through CanMap Streetfiles, which includes geocodes of each point's precise location. These data are available to researchers from their university data library and Esri Canada, but primarily available to private sector and government markets. That said, the goal of the current paper is to encourage researchers to access this rich yet under‐utilized data source. Each service, business, or resource in the DMTI Spatial database is assigned to a respective category using Standard Industrial Classification codes and North American Industrial Classification System codes. It is not clear, however, which is the more reliable coding criteria. We provide an overview of our review of DMTI Spatial data and take‐away suggestions for using this valuable resource for future research on meso‐level residential markers. Key messages: The goal of this paper is to outline existing data source(s) and measures from DMTI Spatial that might help capture meso‐level residential institutions.We recommend "best practices" for using DMTI Spatial data in researchers' own work to capture neighbourhood resources/amenities, or the social infrastructure of the community using either Standard Industrial Classification codes or North American Industrial Classification System codes.We conclude that Standard Industrial Classification codes in DMTI Spatial enhanced points of interest data are more complete—and more accurate—than North American Industrial Classification System codes.

On-demand transit (ODT) has been widely piloted in recent years by many transit agencies in response to changing travel behaviour and preferences among people. Some agencies have adopted ODT to replace underperforming bus routes, as part of a continuous service planning process while others incorporated it within network re-design. All these trends highlight the critical need for transit agencies to have guidance for incorporating ODT into transit network planning both at the strategic, tactical, and service planning levels. Thus, the purpose of this research is to provide a discussion of the key guiding principles to facilitate the development of transit networks with integrated on-demand and scheduled services. To achieve this goal, a thorough review of the states of practice and research was conducted. Findings from the practice review were also reinforced through ODT practitioners' engagement in Canada. This paper provides discussions on the service goals and objectives of an integrated network design and highlights the key planning requirements for developing integrated networks. At the service planning level, the paper provides a discussion on service goals, service design parameters, and scenario development of ODT service. • On-demand transit (ODT) have grown in many cities around the globe, mostly as pilot projects. • Review of the literature and practice shows that planning for ODT is based on best practices , without "built" guidelines. • Principles of planning are discussed within two applications, the network design level, and the service planning level. • Opportunities of integration and mode selection criteria are defined to integrated ODT with existing bus network. • Simulation and analytical tools are useful to complement the principles of planning in the decision-making processes.

As a registered psychotherapist and art therapist, my clinical training was primarily based on North American clinical approaches influenced by traditional Euro and western‐centric clinical theories of human behavior. I completed my training feeling certain that traditional clinical mental health practices were not an appropriate fit for racialized communities and could have negative implications for their healing and well‐being. As clinicians, it is our moral obligation to support and enhance the quality of life for marginalized groups. We can do this by challenging our values and knowledge that have been defined and influenced by structures (i.e., education, training, etc.) embedded in these colonial teachings. For this paper, I used a heuristic self‐inquiry research method to investigate these concerns. I interviewed other racialized psychotherapists practicing in Turtle Island (currently mostly occupied by the political entities of Canada and the United States) with the aim to learn how and if decolonization can be used in therapy practice. With this research, I (1) identified a gap in care for racialized communities, (2) questioned if or how a decolonizing approach to care should be considered, (3) explored my discomfort with practitioners in the field that claim their position on decolonizing therapy, practice, and approaches, and lastly (4) propose other ways of knowing that can inform new ways of practicing therapy. The results of this research helped to problematize the language and use of decolonizing therapeutic practices while learning about other concepts that may be relevant yet distinct, such as principles of coloniality/decoloniality. Those of us, therapists or researchers, wanting to disrupt the current practice of therapy need to work together, share knowledge, and challenge each other, so that we can transform the way we practice as psychotherapists. This paper is my contribution to this conversation. Highlights: I interviewed racialized psychotherapists to learn how and if decolonization can be used in therapy.Traditional psychology can lead to ineffective mental health care for racialized communities.I propose other ways of knowing that can inform new therapy practices for racialized communities.

Using the example of an industrial site in Edmonton, Alberta, this paper argues that industrial ruins represent instantiations of abstract abandonment, a kind of real abstraction that directly articulates to the logic of capital. Drawing from excavations of the industrial ruins of Mill Creek Ravine, one of the first industrial areas in Edmonton, this paper reveals how sites of abstract abandonment congeal critical histories of both abandonment and its afterlives. The history of these ruins, and the communities that emerged after they were abandoned materialize the failures of capitalist fantasies, as well as the sprouts that grow in its cracks.

As opioid fatalities rise in North America, the need to improve the supports available to those who are dependent on opioids and pregnant has become more urgent. This paper discusses the social organisation of drug treatment supports for those who are pregnant, using Canadian clinical practice guidelines (CPGs) for methadone maintenance treatment (MMT) as a case study. Pregnant patients are a priority population for MMT, both in Canada and internationally; the regulatory bodies that oversee MMT in Canada are the provincial Colleges of Physician and Surgeons and Health Canada. The paper analyses MMT CPGs published by these agencies, comparing their general recommendations to those specific to pregnant patients. We demonstrate that the guidelines address few treatment considerations for pregnant patients, other than improved birth outcomes and child welfare, despite acknowledging their more complex needs. Drawing on social science studies of gender and drugs, we argue that MMT CPGs therefore perpetuate the intensified surveillance and foetal prioritisation that have long generated barriers to care for opiate‐dependent pregnant patients. We also discuss how and why the CPGs ultimately only reinforced these current limitations in the drug treatment sector. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this paper is to add to the research literature and begin to fill the gap in knowledge about shared parenting arrangements for women with young children and who have experienced domestic violence (DV), in three Canadian provinces; Alberta, Manitoba and Ontario. Method: This paper reports on the qualitative findings from a mixed methods study on shared parenting from women with children ages 4 and under. Twenty women participated in one-on-one individual interviews through electronic platform utilizing Zoom. Thematic analysis is used to analyze the data. Results: Despite efforts to not exclusively recruit women who had experienced domestic violence (DV) from their former partner, all participants identified as survivors of DV and ongoing survivors of DV, specifically, coercive controlling behaviours. Five themes describe the women's experiences of shared parenting with young children: 1) walking a tight-rope; 2) navigating post-separation relationships; 3) emotional realities of shared parenting; 4) shared parenting outcomes; and, 5) structural challenges. Conclusions: This paper not only adds to the significant and longstanding gap in knowledge directly from women with children ages 4 and under in shared parenting relationships, and who have experienced DV, and also helps to inform social service and legal actors. It is timely with the amendments to the Divorce Act in Canada which now includes DV as a factor in determining the best interests of the child. [ABSTRACT FROM AUTHOR]

In 2015, The Truth and Reconciliation Report (TRC) was released in Canada, outlining 94 Calls to Action which, include pushing Canadian post-secondary institutions to ethically engage Indigenous communities and knowledge systems. This paper seeks to respond to the TRC by offering a spatial analysis of the differences, broadly conceived, between Indigenous and western ontological structures. We consider these differences in terms of 'circles and lines' through a novice, settler understanding of how Mi'kmaw concepts of etuaptmumk (two-eyed seeing), netukulimk (conservation laws) and m'sɨt No'kmaq (all our relations) can be brought to support decolonial teaching and learning about such important and urgent matters as climate change. A related goal in this paper is pedagogic: we hope our own ambivalent learning here can be used as an example to reflect deeply on how settlers like us might/should/can't work with the ethical, political, and practical challenges of responding to the TRC in our research, involving, and considering Indigenous ways of knowing and being.

This paper explores the corporate social responsibility (CSR) landscape for Canadian mining transnational corporations (TNCs) in the wake of the landmark decision of the Supreme Court of Canada in Nevsun Resources Ltd v Araya, which settles, as concrete law, the right of foreign victims of transnational torts committed by Canadian TNCs to bring an action in Canadian courts. The paper acknowledges that there has been an increasing tendency by the Canadian government to create, by way of legislation, legal responsibility for some of the corporate behaviours that had been only governed by CSR initiatives. It argues that the right of action established in the Supreme Court decision adds to the introduction of legal responsibility into the realm of social responsibility, thus calling into question the continuing relevance of CSR initiatives for mining TNCs. It concludes that despite the apparent encroachment upon the social responsibility sphere by legal responsibility, CSR initiatives still hold a place of importance for mining TNCs. Canadian mining TNCs will continue to use the CSR front to gain acceptance in local communities, but may now be potentially held legally responsible through extraterritorial litigation in Canada when their activities run afoul of their own CSR creed or programme and/or violate the rights of local people in their host countries.

This research investigates the double tracking control problem for the complex dynamic network (CDN) with an unavailable link state. Firstly, from the angle of a large-scale system, the dynamical model of CDN is described by the vector differential equations, which consists of node dynamic subsystem (NDS) and link dynamic subsystem (LDS), in which the weighted-values of links are regarded as the state variables of LDS. Secondly, to realise the double tracking control (DT-Control) of CDN, the presented DT-Control scheme in this paper includes the synthesis of controller for NDS and the coupling term in LDS, which can ensure that the two subsystems track the given reference targets. The tracking of NDS contains the synchronisation of nodes as the special case, and the tracking of LDS shows that the eventual topologic structure of CDN will be determined only by the given link reference signal. Due to the economic and technological limitations of sensors in the practice applications, this paper assumes that the state variables of LDS are unavailable in the DT-Control scheme. Finally, the engineering simulation example is given to verify the validity of DT-Control scheme proposed in this paper. [ABSTRACT FROM AUTHOR]

This paper contributes to migration studies, settler colonial studies and critical internationalization studies by mapping as connected two concurrent settler colonial preoccupations, reconciliation and internationalization. In Canada, as in other Western countries, international students are a crucial resource as they increasingly sustain post-secondary funding. At the same time, the Truth and Reconciliation Commission (2015) has charged the educational sector to put reconciliation and decolonization at the heart of their mandate. Drawing on interviews with racialized international students in Ontario, Canada, this paper examines how racialized international students may have complex relationships to coloniality and be complicit in legitimating settler colonialism. We argue that the processes of reconciliation and internationalization must be understood as deeply interconnected especially because the obfuscation of coloniality is a key technology of settler rule.

Independent mobility is an important component of healthy ageing. Public transit may be an affordable way to achieve independent mobility, and yet little is known about older adults' transition to public transit. This paper addresses this research gap by providing an exploration of older adults' experiences transitioning to public transit use, and by comparing these experiences to those of older people who have always travelled using transit. Twenty-four older adults (65+) living in Hamilton, Canada, who use public transit completed semi-structured interviews during which they discussed their experiences when they first began to use transit. These experiences are framed herein with the concept self-efficacy, i.e. how one's belief in their ability to complete a task shapes their ability to complete said task. Results indicate that most older adults acquire skills to transition to public transit, such as trip planning, boarding, knowing where to sit and exiting the bus. These skills are developed through practice. As one gains experience, one becomes more confident in their ability to meet their daily travel needs using transit. Therefore, the transition to public transit as an older adult can be more challenging for those with little experience using public transit. This paper highlights the danger of assuming all older adults will effortlessly take up transit and stresses the importance of older adults gaining experience using public transit.

Recent debates surrounding intimate partner violence (IPV) have focused on its gender symmetry and gender-oriented nature. These debates center on findings from various data sources, like victimization or self-reported surveys and police-based reports. Data by Statistics Canada, from 1999 to 2014, has shown that the prevalence of IPV is similar for male and female victims, except for sexual assaults. However, there has been a paucity of studies on the severity and risk factors of IPV against men by female partners. Thus, this paper examines the severity of and risk factors for physical IPV against heterosexual men in Canada using the General Social Survey (Victimization) data of 2014. This study revealed that there is a symmetry in the experiences of physical violence between male and female victims. This study also revealed that male victims experience more severe violence than female victims. Using binary logistic regression analysis, years of dwelling together, the victim's age, childhood victimization, and marijuana use were found to predict physical IPV against heterosexual men. This paper concludes with suggestions about how these predicting factors can be used to identify male victims and the need for a more inclusive approach toward addressing IPV, which should include male victims.

The prevalence of breast cancer amongst older adults in Canada is increasing. This patient population faces unique challenges in the management of breast cancer, as older adults often have distinct biological, psychosocial, and treatment-related considerations. This paper presents an expert consensus of the Canadian treatment landscape, focusing on key considerations for optimizing selection of systemic therapy for advanced breast cancer in older adults. This paper aims to provide evidence-based recommendations and practical guidance for healthcare professionals involved in the care of older adults with breast cancer. By recognizing and addressing the specific needs of older adults, healthcare providers can optimize treatment outcomes and improve the overall quality of care for this population.

The majority of the literature focused on whether consent should be extended to the adolescent population arises from themes adapted from American tort law. In contrast to the USA, Ontario does not delineate an age of consent for medical treatment and relying on American guidelines to guide practice in Ontario is problematic. While the literature is saturated with discussions for and against seeking adolescent consent, there are currently no bioethical guidelines on adolescent consent in the province of Ontario. This paper explores adolescent refusal of care and adolescent request for care in opposition to parental wishes. The paper seeks to answer the following questions: What is the difference between an adolescent and an adult in medical decision-making? What are the barriers to seeking adolescent consent? And, can the neurobiological argument be an accurate guide for obtaining adolescent consent? [ABSTRACT FROM AUTHOR]

This paper investigates how positive and negative work-personal life interface constructs are differentially associated with intentions to stay in or leave the profession. The findings help map work-personal life interface constructs on the typology of determinants of intention to stay and intention to leave (disengagers, retainers, criticals, and neutrals). The ordered logistic regression (ologit) modelling of cross-sectional data from a representative sample (n = 601) of midwives in Canada shows that work interference with personal life is a disengager, which has a stronger association with intention to leave than with intention to stay in the profession. Among the work-personal life interface constructs, work enhancement of personal life seems to be the most critical determinant, showing the most substantive association with both intention to stay and intention to leave. This finding suggests that interventions to increase midwives' intention to stay and decrease their intention to leave should focus on amplifying the enhancing effects of working on midwives' personal lives. Interventions that aim to reduce work interference with personal life might be more effective in decreasing intention to leave the profession than increasing intention to stay.

In 2020–2021, a qualitative study was undertaken using an interpretive description methodology to identify what triggers grief in the first 2 years following the death of a beloved family member, and to gain other helpful insights about grief triggers from bereaved Canadian adult volunteers. In that study, a purposive sampling method was used to select 10 bereaved Canadian adult volunteers for in-depth, semi-structured interviews. This paper reports on the humor findings, as revealed to be a particularly complex grief trigger for many participants, as well as a periodic way for most to manage or live with their grief. Participant quotes and an extended discussion are included to illustrate the importance of these humor findings in relation to grief, and to inform bereaved people, bereavement service providers, and the general public about both helpful aspects and some cautionary considerations about humor.

As both a marriage act and an immigration act, the Expatriation Act of 1907 restricted U.S. women's freedom of marriage by stating that marrying aliens would lead to loss of U.S. citizenship. To study the effects of the Expatriation Act, I conduct a statistical analysis using 1910 full-count U.S. census data. I find that the Expatriation Act of 1907 generated significantly negative effects on intermarriage between American women and foreign-born men, particularly noncitizens. In particular, I find that it was the citizenship, rather than men's non-U.S. origin, that accounted for the negative effects of the Expatriation Act of 1907 on intermarriage. These results show a decline in male immigrants' marital assimilation, and potentially social and economic assimilation. As for the magnitude, the effects were large: the decline in intermarriage was at least 15 percent relative to the pre-Act intermarriage rate. Besides these main results, selective emigration to Canada and Europe driven by intermarriage cannot explain the main empirical results of the paper. The Expatriation Act of 1907 also had no significant effects on women's entry into the marriage market. Finally, the effects of the Expatriation Act of 1907 on intermarriage were heterogeneous by family immigration background, but less so by geographic region. [ABSTRACT FROM AUTHOR]

Climate change increases the risk of illness through rising temperature, severe precipitation and worst air pollution. This paper investigates how monthly excess mortality rate is associated with the increasing frequency and severity of extreme temperature in Canada during 2000-2020. The extreme associations were compared among four age groups across five sub-blocks of Canada based on the datasets of monthly T90 and T10, the two most representative indices of severe weather monitoring measures developed by the actuarial associations in Canada and US. We utilize a combined seasonal Auto-regressive Integrated Moving Average (ARIMA) and bivariate Peaks-Over-Threshold (POT) method to investigate the extreme association via the extreme tail index χ and Pickands dependence function plots. It turns out that it is likely (more than 10%) to occur with excess mortality if there are unusual low temperature with extreme intensity (all χ > 0.1 except Northeast Atlantic (NEA), Northern Plains (NPL) and Northwest Pacific (NWP) for age group 0-44), while extreme frequent high temperature seems not to affect health significantly (all χ ≤ 0.001 except NWP). Particular attention should be paid to NWP and Central Arctic (CAR) since population health therein is highly associated with both extreme frequent high and low temperatures (both χ = 0.3182 for all age groups). The revealed extreme dependence is expected to help stakeholders avoid significant ramifications with targeted health protection strategies from unexpected consequences of extreme weather events. The novel extremal dependence methodology is promisingly applied in further studies of the interplay between extreme meteorological exposures, social-economic factors and health outcomes.

Artificial Intelligence (AI) carries the potential for unprecedented disruption in radiology, with possible positive and negative consequences. The integration of AI in radiology holds the potential to revolutionize healthcare practices by advancing diagnosis, quantification, and management of multiple medical conditions. Nevertheless, the ever‑growing availability of AI tools in radiology highlights an increasing need to critically evaluate claims for its utility and to differentiate safe product offerings from potentially harmful, or fundamentally unhelpful ones. This multi‑society paper, presenting the views of Radiology Societies in the USA, Canada, Europe, Australia, and New Zealand, defines the potential practical problems and ethical issues surrounding the incorporation of AI into radiological practice. In addition to delineating the main points of concern that developers, regulators, and purchasers of AI tools should consider prior to their introduction into clinical practice, this statement also suggests methods to monitor their stability and safety in clinical use, and their suitability for possible autonomous function. This statement is intended to serve as a useful summary of the practical issues which should be considered by all parties involved in the development of radiology AI resources, and their implementation as clinical tools.

The unprecedented participation by two Ojibwe-speaking Anishinabek lay delegates in the 1866 meeting of the Electoral Synod of the Anglican Diocese of Toronto garnered a brief flurry of contemporary journalistic coverage across a networked imperial and colonial press. In the most vivid reportage, the two delegates were dehumanized, reduced to the status of 'Indian nags ... becoming inoculated with the ways of Anglicans'. In another more distantly circulated representation, an Indigenous presence at the incipience of Canadian synodality was invested with different rhetorical significance, the unsettling scandal of their voting membership justifying the struggle for self-government in the nascent Anglican Churches of other colonies, thus laying bare anxieties about the precarious situation of colonial Anglicanism. Rather than presuming to interpret the experience and discourse of Indigenous Anglicans, nor simply documenting the first local episode of formal Indigenous involvement in the counsels of Anglicans in Canada, this paper introduces the Electoral Synod, the neglected texts that covered the event, along with the lives of the exoticized churchmen featured in their coverage.

This article is prepared by the Association of Professors of Gynecology and Obstetrics Undergraduate Medical Education Committee and provides educators recommendations for optimizing inclusive education for our students with disabilities. Medical educators are increasingly encountering students with disabilities and have the responsibility of ensuring requirements are met. Medical education committee members from the US and Canada reviewed the literature on disabilities in medical student education to identify best practices and key discussion points. An iterative review process was used to determine the contents of an informative paper. Medical schools are required to develop technical standards for admission, retention, and graduation of their students to practice medicine safely and effectively with reasonable accommodation. A review of the literature and obstetrics and gynecology expert opinion formed a practical list of accommodation strategies and administrative steps to assist educators and students. Medical schools must support the inclusion of students with disabilities. We recommend a collaborative approach to the interactive process of determining reasonable and effective accommodations that includes the students, a disability resource professional and faculty as needed. Recruiting and supporting medical students with a disability strengthens the diversity commitment and creates a more inclusive workforce. Medical School Education Medical schools have the responsibility to train a diverse physician workforce including those with disabilities. The integration of students with disabilities is important and should be done in a structured and timely manner that maximizes the individual's abilities and incorporates reasonable accommodations in the clinical learning environment. Though the definition of disability traverses a wide variety of diagnoses, this review highlights sensory and physical disabilities and the various accommodations to facilitate access and successful completion of required objectives.

With the continuous improvement of shale oil and gas recovery technologies and achievements, a large amount of geological information and data have been accumulated for the description of shale reservoirs, and it has become possible to use machine learning methods for "sweet spots" prediction in shale oil and gas areas. Taking the Duvernay shale oil and gas field in Canada as an example, this paper attempts to build recoverable shale oil and gas reserve prediction models using machine learning methods and geological and development big data, to predict the distribution of recoverable shale oil and gas reserves and provide a basis for well location deployment and engineering modifications. The research results of the machine learning model in this study are as follows: ① Three machine learning methods were applied to build a prediction model and random forest showed the best performance. The R2 values of the built recoverable shale oil and gas reserves prediction models are 0.7894 and 0.8210, respectively, with an accuracy that meets the requirements of production applications; ② The geological main controlling factors for recoverable shale oil and gas reserves in this area are organic matter maturity and total organic carbon (TOC), followed by porosity and effective thickness; the main controlling factor for engineering modifications is the total proppant volume, followed by total stages and horizontal lateral length; ③ The abundance of recoverable shale oil and gas reserves in the central part of the study area is predicted to be relatively high, which makes it a favorable area for future well location deployment.

Although women's representation in STEM fields and occupations has increased, science and math continue to be stereotyped as male domains. This paper links psychological and sociological explanations for gendered disparities in STEM by examining the relationship between the local "micro-situational" female learning environment and the gender gap in academic self-concept in math and science. We applied hybrid models to TIMSS 2015 data comprised of a pseudo-panel of repeated measures for individual student and peer achievement, academic self-concept, utility value, and interest-enjoyment value in math/science (at age 14). We analyzed data from three countries, including a subsample of students who were taught by the same teacher in both math and science, thus eliminating unobserved teacher heterogeneity. Results indicate that female peer climate in the classroom is important for understanding how girls' self-concept in math/science is formed, even though it was unrelated to the gender gap.
