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]

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]

Exam period can be a stressful time for students, and having examples of past papers to help prepare for the tests can be extremely helpful. It is possible that past exams are already shared on your campus--by professors in their specific courses, via student unions or groups, or between individual students. In this article, we will go over the workflows and infrastructure to support the systematic collection, provision of access to, and repository management of past exam papers. We will discuss platform-agnostic considerations of opt-in versus opt-out submission, access restriction, discovery, retention schedules, and more. Finally, we will share the University of Toronto setup, including a dedicated instance of DSpace, batch metadata creation and ingest scripts, and our submission and retention workflows that take into account the varying needs of stakeholders across our three campuses.

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]

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]

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]

Users' experiences in mental health assessment are multifaceted, including their emotional experiences. Yet, studies of mobile apps for psychiatric assessment have centered on diagnostic accuracy and perceived usability, with little consideration of the impact of user emotional experiences. In this study, we focused on users' perceived usability and emotions and compared the user experience of a paper-and-pencil and an app-based collection of mental health screening questionnaires: EarlyDetect. The System Usability Scale (SUS) and modality-directed emotion questionnaires were administered using paper-and-pencil or iPad. Modality was assigned pseudo-randomly on patients' first visit at a referral-based mental health clinic. We found that patients assigned to the iPad app reported a significantly higher SUS score than patients assigned to paper-and-pencil, qualified by a modality-by-gender interaction where modality effects were significant for men but not for women. Moreover, enjoyment was positively linked to perceived usability, whereas boredom, frustration, and anxiety were negatively linked to usability. Our findings illustrate the added value of studying user experience applied to psychiatric assessments, where both emotions and gender-specific user experience should be taken into consideration. We further discuss the implications for psychiatric assessments via app versus traditional data collection. [ABSTRACT FROM AUTHOR]

We analyze the total factor productivity (TFP) of the pulp and paper industry in three Canadian provinces (British Columbia, Ontario, and Quebec) and in three United States (US) states that are contiguously located south of the border (Washington, Illinois, and Maine) over the period of 1971 to 2005. We find that the industry in the three Canadian provinces had much higher TFP growth rates in the era following the Free-Trade Agreement (FTA) signed in 1988. In terms of productivity level, this relative TFP surge allowed the industry in Ontario and British Columbia to move ahead of Illinois and Washington, respectively; however, Quebec trailed further Maine, which is the overall leader in the sample. Our results in this particular case reveal that the Canadian pulp and paper industry did not contribute to the overall Canada-US productivity gap. [ABSTRACT FROM AUTHOR]

The Canadian Association of Radiologists Incidental Findings Working Group consists of both academic subspecialty and general radiologists and is tasked with adapting and expanding upon the American College of Radiology incidental findings white papers to more closely apply to Canadian practice patterns, particularly more comprehensively dealing with the role of ultrasound and pursuing more cost-effective approaches to the workup of incidental findings without compromising patient care. Presented here are the 2020 Canadian guidelines for the management of hepatobiliary incidental findings. Topics covered include initial assessment of hepatic steatosis and cirrhosis, the workup of incidental liver masses identified on ultrasound and computed tomography (with algorithms presented), incidental gallbladder findings (wall thickening, calcification, and polyps), and management of incidental biliary dilatation.

The Physical Activity Neighborhood Environment Scale (PANES) has been used internationally; however, PANES properties have not been assessed in all geographical contexts. Our objectives were to assess the reliability and validity of an online and paper version of the PANES in Canadian adults. Reliability was estimated using intraclass correlation coefficients (ICC), percent of overall agreement (p0) and Cohen's Kappa coefficient (κ). Lower 95% confidence interval (CI) ICC ranged from 0.10 to 0.70. Lower 95%CI for κ statistics ranged from −0.20 to 0.64 and p0 ranged from 80.1% to 95.7%. Cronbach's alpha coefficients (α) estimated internal consistency of the PANES (α = 0.58 for the paper version and α = 0.55 for the online version). Mean scores for the PANES Built Environment Index (BEI) significantly differed by neighborhood street pattern (p <.05). The PANES administrated via paper or online provides reliable overall agreement and valid estimates of the self-reported neighborhood built environment supportiveness of physical activity.

Since 2017, four provincial legislatures have introduced bills invoking the controversial notwithstanding clause. We present an original dataset of news articles from 10 different outlets that discussed the clause while these bills were being debated in Saskatchewan and Ontario. Empirically, although the clause is typically portrayed accurately, we find over one-fifth of articles about the clause did not indicate that it must be included in legislation. Normatively, the clause was twice as likely to be portrayed negatively as it was positively, and the type of portrayal was strongly associated with the ideological orientation of the news outlet. The rate of negative portrayals was similar across the two provinces, which suggests that attitudes toward the clause may endure beyond the policy issue itself or the level of media visibility.

The application of big data, radiomics, machine learning, and artificial intelligence (AI) algorithms in radiology requires access to large data sets containing personal health information. Because machine learning projects often require collaboration between different sites or data transfer to a third party, precautions are required to safeguard patient privacy. Safety measures are required to prevent inadvertent access to and transfer of identifiable information. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI Ethical and Legal standing committee with the mandate to guide the medical imaging community in terms of best practices in data management, access to health care data, de-identification, and accountability practices. Part 2 of this article will inform CAR members on the practical aspects of medical imaging de-identification, strengths and limitations of de-identification approaches, list of de-identification software and tools available, and perspectives on future directions.

A vast amount of articles centered on brain metastases have been published. To present the 100 most-cited articles dedicated to brain metastasis and to accomplish a broad literature review. In December 2019, we performed a title-focused search using the Thomson Reuters Web of Science database to identify the most cited articles centered on brain metastatic disease. Our search query term was based on using the following algorithm: "brain metastases" OR "brain metastasis" OR "brain metastatic disease" OR "cerebral metastases" OR "cerebral metastasis" OR "cerebral metastatic disease." Afterward, we reviewed the results to certify that they were relevant to the purposes of our research protocol. The 100 most cited papers were chosen and further analyzed. Our search resulted in 11,579 articles, published from 1975 until the completion of our survey. The most cited article, by Patchell et al., was published in 1990, with 1862 citations, and an average of 62.07 citations per year, whereas the last in our list, by Gaspar et al., was published in 2010, with 195 total citations, and an average of 19.50 citations per year. Countries with the highest-cited articles included the United States (75 records), followed by Canada (16 records). We discovered the top 100 most-cited articles centered on brain metastasis, all of which show a potentially increased level of interest, because they are meaningful scientific reports. In addition, we reviewed the historical development and advances in brain metastasis research and relevant points of interest, alongside the relevant contributions of different authors, fields of special interest, and countries. Many of the most cited articles were written by authors whose specialty was not neurosurgery or by neurosurgeons who were supported by colleagues from other medical fields. As a consequence, many of these articles were not published in neurosurgery-dedicated journals. [ABSTRACT FROM AUTHOR]

Efforts to prevent work-related injuries have met with tangible success in industrialized countries. In Quebec, workplace accidents and occupational illness have declined sharply since the end of the 1990s. However, there is still considerable room for improvement in small and medium-sized enterprises (SMEs). Expert specialists in accident prevention in SMEs are overloaded. Their interventions are repetitive and not personalised. Few tools are available for accelerating the process of evaluating occupational health and safety (OHS) performance. The aim of this research project was to address this deficiency by proposing a novel OHS performance evaluation tool better adapted to SMEs. For this purpose, research was carried out in two distinct phases. The first phase led to the theoretical model on which the tool is based. The second phase was carried out using an action research approach. The proposed tool was designed and improved during this phase, through field-testing and the involvement of a Quebec industrial partner. In spite of the limitations of this research, we have succeeded in developing a new tool with software support adapted specifically for the evaluation of OHS performance in SMEs. Upon completion of the project, a tested and improved version of the tool was delivered to the industrial partner. Experts in accident prevention have found the tool to be reliable and helpful. It has accelerated the identification of deficiencies in OHS management in several SMEs and has helped specialists to develop personalized and better-focused plans of action. [ABSTRACT FROM AUTHOR]

This paper explores the relationships between low‐income single mothers and their adolescent and early adult children utilizing qualitative interview and focus group data with youth from three Canadian cities. The research explored youth provisioning roles in these families. Provisioning, a concept widely understood in the global south, refers to labour used to sustain low‐income families and includes emotional labour, care work, trade and exchange and paid labour. Findings from this study identified strong expressions of positive attachment and close relationships between youth and their family members. The paper queries whether positive attachment may be built through roles where youth see themselves as integral parts of a family team and where their contributions are acknowledged. These findings invite us to explore and perhaps challenge the oft‐reported correlations between living in a low‐income, lone mother‐led family and poor childhood outcomes and poor attachment. Can these outcomes be mediated and can the provisioning roles youth undertake possibly be such mediators? [ABSTRACT FROM AUTHOR]

Based upon qualitative interviews with 54 women and men living with HIV across Ontario, Canada, this paper examines the impact of HIV criminalization on the sexual and romantic relationships of people living with HIV. This research highlights the navigation strategies people living with HIV create and employ to both navigate and protect themselves from the law. Through a thematic and intersectional analysis, this study shows how adoption of these strategies is unequal, with access to navigation strategies varying along lines of gender, race, and sexual orientation. As a result, women and racialized people living with HIV face more difficulties navigating the impact of the law. HIV criminalization in Canada fuels and validates HIV stigma and produces vulnerability both within and outside of the relationships of people living with HIV. This paper seeks to understand HIV criminalization from the perspective of those governed by the law, in hopes of producing knowledge which will contribute to legal reform, inform policy, and support the development of efficacious secondary prevention initiatives.

This paper focuses on the methodological and empirical challenges researchers encounter when accessing government open data through the case study of Canada's Open Government Action Plan, with a specific emphasis on datasets hosted by the House of Commons. To address these challenges, we have created an R package designed to streamline the retrieval process of datasets, that are not-so-user-friendly, from the House of Commons website. Furthermore, we have made complete datasets available in both French and English, which are the official languages of Canada, and in multiple formats to improve accessibility. Our package aims to be an invaluable resource for researchers interested in Canadian politics or conducting comparative research. Therefore, a portion of this paper is allocated to showcase the potential utility of our package. Through our research, we highlighted three crucial lessons: firstly, the heterogeneous nature of datasets requires flexibility and adaptability; secondly, open data curators encounter various challenges in addressing user-reported issues; and thirdly, there is a nuanced understanding of "openness" in government datasets. In conclusion, we reflect on the potential scalability of open data initiatives while advocating for a nuanced approach that considers the complex challenges associated with open data accessibility.

Geometrically, a complex dynamical network (CDN) can be regarded as the interconnected system composed of the node subsystem (NS) and the link subsystem (LS) coupled with each other. Guided by this idea, in order to achieve the goal of each node following asymptotically its own reference target in a CDN, this paper investigates the model following adaptive control (MFAC) problem of NS via the dynamics of links, which implies that the LS plays the important dynamic auxiliary role in the MFAC realization of nodes. Meanwhile, we focus on the condition that the links state information is unavailable, due to sensor practical application and measurement cost constraints. To obviate this restriction, we construct the asymptotical state observer for the LS. Next, to achieve the control goal of this paper, an appropriate Lyapunov candidate function is selected, by which the MFAC scheme for NS is synthesized based on the state observer of LS. Finally, the simulation example is performed to demonstrate the theoretical results in this paper. [ABSTRACT FROM AUTHOR]

There is an increasing need of gerontological education in social work to enhance the knowledge of aging and interests in senior care among students. This study is conducted based on an experiential-learning strategy with a combination of having an ethnographic interview with an older adult and writing a reflection paper afterward as an assignment embedded in a Gerontology course of the Bachelor of Social Work program in western Canada. Thematic analysis was applied to eight reflection papers in which a consent was obtained from 2020 to 2021 cohorts of social work students. Three key themes emerged: connection between learned knowledge and interview topics, resonation interview content with personal experiences, and a positive perception of aging and a positive attitude toward working with aging populations. The findings support the combination of ethnographic interview and reflection paper as a pedagogical approach in gerontological education not only for improving students’ learning experience and knowledge but also for establishing a positive perception of aging and older adults. The study also reveals the necessity of more interaction between students and older adults to enhance a better understanding of aging-related issues and promote willingness to work with older adults.

This paper investigates the possibilities and challenges of using mass timber as a sustainable alternative for retrofitting existing buildings in Canada. To create the knowledge foundation on which to devise a holistic framework tailored to the specific characteristics of Canada's built environment, a detailed analysis of the types, geographical distribution, structural, and energy features of the local building stock is first presented. Then, previous strategies for enhancing and upgrading existing buildings with engineered timber are reviewed, classified, and evaluated. Finally, to explore economic and environmental implications, a detailed assessment of available life-cycle cost–benefit analysis approaches is conducted alongside their adaptation to Canada's building context. The findings of this paper can inform policymakers, builders, and designers in developing more sustainable building retrofit practices, design, and regulations, in line with Canada's efforts toward net zero emissions.

This paper reports on how service providers and academic researchers partnered to support the journey of a primary prevention organization in western Canada as they reviewed their programming against an evidence-based practice (EBP) framework. The process allows the organization to increase their EBP culture by encouraging staff understanding and uptake of their nine family support programs. It also informs service users and other stakeholders of the evidentiary status of different kinds of support services. In this way, the families become more informed and engaged partners who might easily evaluate the respective risks and benefits of the various applications. As part of the process, an evidence-based framework used a common language to assess the efficacy of the respective nine programs. All nine programs are now mapped into the EBP framework. This review allows staff to become more intentional and informed about the EBPs they employ to support vulnerable families and to use this knowledge to better inform the families with whom they work. This paper and the process the agency followed can be a model for other organizations who serve families experiencing short-term housing crisis, provide infant nursery care, and other support services for families with young children.

Despite the gendered rebalancing of enrolments in higher education (HE) in the West, the underrepresentation of women in science, technology, engineering and mathematics (STEM) disciplines persists. Gendered selectivity of field of study influences higher education student migration (HESM) and in turn sheds light on HE participation. Framed by gender intersectionality theories both in HE studies and migration scholarship, this paper uses innovative data to analyse the intersectional effect of gender and field of study on HESM in Canada. Based on Statistics Canada's postsecondary student information system for the 2019/20 academic year, Canadian interregional flow matrixes structured by gender, field and level of study are constructed and analysed. The results show compelling evidence of the influence of gendered differences in HESM when intersected with field and level of study. Notably, women pursuing STEM studies migrate significantly more than any other grouping (i.e. gender, field and level of study groupings). The paper concludes with a discussion of policy implications for the influence of HESM on community demographic make‐up and local labour markets, as well as future research including the need to understand gendered dimensions of migration intentions and motivations.

Artificial intelligence (AI) software that analyzes medical images is becoming increasingly prevalent. Unlike earlier generations of AI software, which relied on expert knowledge to identify imaging features, machine learning approaches automatically learn to recognize these features. However, the promise of accurate personalized medicine can only be fulfilled with access to large quantities of medical data from patients. This data could be used for purposes such as predicting disease, diagnosis, treatment optimization, and prognostication. Radiology is positioned to lead development and implementation of AI algorithms and to manage the associated ethical and legal challenges. This white paper from the Canadian Association of Radiologists provides a framework for study of the legal and ethical issues related to AI in medical imaging, related to patient data (privacy, confidentiality, ownership, and sharing); algorithms (levels of autonomy, liability, and jurisprudence); practice (best practices and current legal framework); and finally, opportunities in AI from the perspective of a universal health care system.

This introduction to the special feature describes the development and application of a "full-spectrum sustainability" evaluation framework that emerged from a transdisciplinary research process. The framework and corresponding case studies described in this paper originated in the work of a Canadian Fisheries Research Network project that sought to enhance fisheries management by including diverse social-ecological considerations in fisheries management evaluation. The first section discusses the tendency of sustainability evaluation frameworks in fisheries to focus on ecological and economic considerations and introduces the Canadian Fisheries Research Network's four pillar approach, which includes ecological, economic, social and cultural, and institutional/ governance categories. To illustrate the comprehensive nature of this framework, the second section provides a comparison of the framework with elements in the United Nation's Sustainable Development Goals. The third section provides an overview of the eight papers in this special feature that explore the development and application of full-spectrum sustainability. The conclusion synthesizes some key findings, highlighting four overall critical and ongoing challenges associated with advancing full-spectrum sustainability evaluation in Canada and elsewhere: the politics of transdisciplinary research; integrating social considerations into management agencies reluctant to move beyond ecological and economic considerations; dynamic and diverse issues involved in supporting robust and inclusive governance processes; and translating technical frameworks into usable practical instruments for different societal actors.

This paper focuses on the contradictory nature and sometimes unintended consequences of workers' efforts to defend particular communities against the ravages of capital restructuring. In the past decade, pattern collective bargaining in the highly unionized British Columbia pulp and paper industry has faced enormous strains due to intense industry restructuring. Our analysis focuses on the repercussions of actions taken by union locals in two British Columbia towns-Port Alice and Port Alberni-to try to secure the survival of their pulp and paper mills and, even in the case of Port Alice, the continued existence of the community. Our analysis resonates with recent debates surrounding worker agency as well as writing in the 1980s which addressed the often contradictory and problematic nature of workers' struggles to 'defend place'; writing largely neglected in more recent work in labour geography.

Greenhouse gas (GHG) emissions of the Quebec pulp and paper industry fell by more than 30 percent from 1990 to 2006. We use an energy demand model to analyze the contributions to this decrease of energy prices, product mix, technological change, and biomass use. The product mix is made of pulp, and cardboard, and paper. Pulp is an intermediate product for the industry, but not necessarily so for mills; vertical integration varies across mills and presents different opportunities to transfer heat between stages of production. Chemical and mechanical pulping processes are used to form two groups of pulp and paper mills. We find that changes of product mixes contributed the most to reduce GHG emissions, followed to a lesser extent by increases of fuel prices relative to electricity. The estimated electricity and fuel price elasticities are low. However it is still possible to significantly reduce GHG emissions by substituting natural gas for heavy fuel oil; such a substitution could be brought about by a small change of their relative price.

River ice is a common occurrence in cold climate hydrological systems. The annual cycle of river ice formation, growth, decay and clearance can include low flows and ice jams, as well as mid-winter and spring break-up events. Reports and associated data on river ice occurrence are often limited to site and season-specific studies. Within Canada, the National Hydrometric Program (NHP) operates a network of gauging stations with water level as the primary measured variable to derive discharge. In the late 1990s, the Water Science and Technology Directorate of Environment and Climate Change Canada initiated a long-term effort to compile, archive and extract river ice related information from NHP hydrometric records. This data article describes the original research data set produced by this near 20-year effort: the Canadian River Ice Database (CRID). The CRID holds almost 73,000 variables from a network of 196 NHP stations throughout Canada that were in operation within the period 1894 to 2015. Over 100,000 paper and digital files were reviewed representing 10,378 station-years of active operation. The task of compiling this database involved manual extraction and input of more than 460,000 data entries on water level, discharge, date, time and data quality rating. Guidelines on the data extraction, rating procedure and challenges are provided. At each location, a time series of up to 15 variables specific to the occurrence of freeze-up and winter-low events, mid-winter break-up, ice thickness, spring break-up and maximum open-water level were compiled. This database follows up on several earlier efforts to compile information on river ice, which are summarized herein, and expands the scope and detail for use in Canadian river ice research and applications. Following the Government of Canada Open Data initiative, this original river ice data set is available at: https://doi.org/10.18164/c21e1852-ba8e-44af-bc13-48eeedfcf2f4 (de Rham et al., 2020).

Abstract Scope Antibiotic stewardship programmes (ASPs) are necessary in hospitals to improve the judicious use of antibiotics. While ASPs require complex change of key behaviours on individual, team organization and policy levels, evidence from the behavioural sciences is underutilized in antibiotic stewardship studies across the world, including high-income countries (HICs). A consensus procedure was performed to propose research priority areas for optimizing effective implementation of ASPs in hospital settings using a behavioural perspective. Methods A workgroup for behavioural approaches to ASPs was convened in response to the fourth call for leading expert network proposals by the Joint Programming Initiative on Antimicrobial Resistance (JPIAMR). Eighteen clinical and academic specialists in antibiotic stewardship, implementation science and behaviour change from four HICs with publicly funded healthcare systems (e.g. Canada, Germany, Norway and the UK) met face-to-face to agree on broad research priority areas using a structured consensus method. Question addressed and recommendations : The consensus process assessing the ten identified research priority areas resulted in recommendations that need urgent scientific interest and funding to optimize effective implementation of ASPs for hospital inpatients in HICs with publicly funded healthcare systems. We suggest and detail behavioural science evidence–guided research efforts in the following areas: (a) comprehensively identifying barriers and facilitators to implementing ASPs and clinical recommendations intended to optimize antibiotic prescribing; (b) identifying actors ('who') and actions ('what needs to be done') of ASPs and clinical teams; (c) synthesizing available evidence to support future research and planning for ASPs; (d) specifying the activities in current ASPs with the purpose of defining a control group for comparison with new initiatives; (e) defining a balanced set of outcomes and measures to evaluate the effects of interventions focused on reducing unnecessary exposure to antibiotics; (f) conducting robust evaluations of ASPs with built-in process evaluations and fidelity assessments; (g) defining and designing ASPs; (h) establishing the evidence base for impact of ASPs on resistance; (i) investigating the role and impact of government and policy contexts on ASPs; and (j) understanding what matters to patients in ASPs in hospitals. Conclusions Assessment, revisions and updates of our priority-setting exercise should be considered at intervals of 2 years. To propose research priority areas in low- and middle-income countries, the methodology reported here could be applied. [ABSTRACT FROM AUTHOR]

Abstract Artificial intelligence (AI) is rapidly moving from an experimental phase to an implementation phase in many fields, including medicine. The combination of improved availability of large datasets, increasing computing power, and advances in learning algorithms has created major performance breakthroughs in the development of AI applications. In the last 5 years, AI techniques known as deep learning have delivered rapidly improving performance in image recognition, caption generation, and speech recognition. Radiology, in particular, is a prime candidate for early adoption of these techniques. It is anticipated that the implementation of AI in radiology over the next decade will significantly improve the quality, value, and depth of radiology's contribution to patient care and population health, and will revolutionize radiologists' workflows. The Canadian Association of Radiologists (CAR) is the national voice of radiology committed to promoting the highest standards in patient-centered imaging, lifelong learning, and research. The CAR has created an AI working group with the mandate to discuss and deliberate on practice, policy, and patient care issues related to the introduction and implementation of AI in imaging. This white paper provides recommendations for the CAR derived from deliberations between members of the AI working group. This white paper on AI in radiology will inform CAR members and policymakers on key terminology, educational needs of members, research and development, partnerships, potential clinical applications, implementation, structure and governance, role of radiologists, and potential impact of AI on radiology in Canada.

This article is a review of research efforts over the last decade on the sources and characteristics of substances in Canadian pulp mill effluents associated with two responses in fish: (1) induction of detoxification enzymes and (2) reproductive effects. The initial uncertainty regarding the role of chlorine bleaching and dioxins in these responses was resolved by the mid 1990s, when it was determined that effects were not correlated with effluent adsorbable organic halogen (AOX) levels and that releases of dioxins had decreased substantially. In the mid 1990s researchers were able to partially attribute enzyme activity induction in fish to wood components, while other studies showed individual wood extractives had the potential to affect fish reproduction. A lack of correlation between threshold reproductive responses and effluent concentrations indicated additional unidentified compounds and mechanisms were involved. In the late 1990s, source identification approaches in concert with the development of mechanistically linked in vitro and in vivo bioassays showed multiple compounds are affecting production and signaling of sex steroids in fish. These substances are bioavailable and accumulated rapidly, consistent with the body of evidence that has shown a sustained exposure is required to produce both elevated enzyme activity and depressions in sex steroid levels. The patterns of these substances in effluents and fish tissues are not correlated with production type or effluent treatment. Collectively, these findings show that bioactive substances originate from wood and are derived from lignin and/or terpenoids, they are liberated during pulp digestion, and in kraft mills they are present in black liquor and chemical recovery condensates. Additional bioactive substances are also present in bleachery effluents containing residual lignin. The lack of a definitive identification of the responsible compounds has prevented an evaluation of the effectiveness of industry-wide process changes. Continued research into the identities, origins, and environmental fate of these substances and the efficacy of effluent treatment is required to determine their significance and relationship to the existing impacts of effluents from pulp and paper mills in Canadian aquatic ecosystems.

Studies conducted in Sweden in the early 1980s provided some of the first evidence that effluents from some pulp mills were capable of inducing toxic responses in fish at very low concentrations in the receiving environment. In response to these findings, studies were initated in Canada and impacts of primary treated bleached kraft mill effluent on reproductive function in fish were found. Reproductive impacts in fish were not limited to mills that used chlorine in the bleaching process and were also evident at some mills that employed secondary effluent treatment. In 1992, new federal regulations were passed under the Canadian Environmental Protection Act to control releases of dioxins and furans, and a new Pulp and Paper Effluent Regulation under the Fisheries Act set stricter limits for biological oxygen demand and total suspended solids. Very importantly, the new regulations included requirements for environmental effects monitoring (EEM) at all mill sites. This allowed the effectiveness of the control limits in protecting fish, fish habitat, and human use of fisheries resources to be assessed. At the same time, the Minister of the Environment launched an intensive government, industry, and university research program. Results from this research program along with feedback from the EEM program would then be used to define what additional control actions might be necessary. This article reviews the field studies and mechanistic research conducted in Canada following the implementation of the new federal regulations. Great progress has been made in this area, first demonstrating reproductive effects at various locations, then determining the mechanisms responsible for the reproductive effects at specific sites, followed by the demonstration of partial recovery in reproductive function following process and treatment changes in response to the new regulations. However, it is clear from the results of the first two cycles of the EEM program that mill effluents still affect the local receiving environments at a number of locations across Canada, and that continued research combining field studies, bioassay application, and chemical identification is required.

Building on breakthroughs recently made at kraft mills, a survey of mechanical pulp and paper mill effluents was undertaken to gain insights concerning potential effects on fish reproduction. Effluents from seven Canadian mills were characterized chemically for conventional parameters such as biochemical oxygen demand (BOD) and total suspended solids (TSS). Each sample was further subjected to solvent extraction followed by gas chromatographic separation for the determination of resin/fatty acids and for the estimation of a gas chromatography (GC) profile index. Each mill effluent was assessed for the potential to affect fish reproduction in the laboratory using a five day adult fathead minnow (Pimephales promelas) egg production bioassay with exposures to 100% effluent. The seven effluents were found to have substantial variation both in terms of chemical characterization and effects on fish reproduction. Temporal variations were also noted in effluent quality at mills sampled on different occasions. Similar to what has been observed for kraft mills, a general trend of greater reductions in egg production caused by effluents with greater BOD concentrations and GC profile indices was noted. Effluents with BOD > 25 mg/L and GC Profile indices >5.0 caused a complete cessation of egg production. At the same time, about half of the total effluents sampled had BOD < 25 mg/L and GC profile indices <5.0 and caused no significant effects on egg production, suggesting these values may be useful as effluent quality targets for mechanical pulp and paper mills. However, 3 out of 14 effluents sampled had BOD < 25 mg/L and GC profile indices <5.0 and caused significant reductions in egg production. The reason(s) for reproductive effects caused by such effluents is presently unclear. The effluent quality parameters considered in this study may require further refinement to address their utility in predicting the adverse reproductive effects induced by effluents from mechanical pulp and paper mills.

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.

Forty-one bacterial strains isolated from the headbox water of two machines in a Canadian paper mill were associated with the genera Asticcacaulis, Acidovorax, Bacillus, Exiguobacterium, Hydrogenophaga, Pseudomonas, Pseudoxanthomonas, Staphylococcus, Stenotrophomonas based on the sequence of their 16S rRNA genes. The metabolic profile of these strains were determined using Biolog EcoPlate, and the bacteria were divided into four metabolic groups. Metabolic profiles of the bacterial communities colonizing the headbox water of two paper machines was also determined weekly over a 1 year period. The only compound that was not reduced by the bacterial community was 2-hydroxybenzoic acid. Utilization frequency of the other carbon sources in the Biolog EcoPlate ranged from 3 to 100%. The metabolic profiles of the bacterial community did not vary considerably between the two paper machines. However, the metabolic profile varied among the sampling dates. [ABSTRACT FROM AUTHOR]

Red heartwood, a dark nonhomogenous discolouration in paper birch trees ( Marsh.), limits the applications and uses of sawn boards to nonvisible low-value products, thus resulting in substantial value loss. The occurrence and distribution of red heartwood were investigated in 12 paper birch trees grown in the province of Quebec, Canada. The youngest tree was 62 years old at breast height and the oldest 86 years old for an average of 75 years old. In this study, 225 occurrences of external traits, relating to branch scars and forks, previously proposed as initiation points for red heartwood were identified and measured. The distribution of red heartwood was digitally mapped and the effect of these external traits on the red heartwood surface and shape inside each tree was examined. Results show that red heartwood initiates from an external trait and that multiple external traits can contribute to the development of a red heartwood column following the longitudinal axis of the stem. Red heartwood appeared to initiate mainly from external traits at the base of the tree. A modelling exercise indicated that the width of the red heartwood column inside a standing tree can be estimated from branch scar width and height from the ground. Tree vigour could not be linked to the proportion of red heartwood inside standing trees. A three-dimensional analysis of log shape could potentially be used to detect red heartwood presence in a log before processing to optimize the log sawing pattern. [ABSTRACT FROM AUTHOR]

Background: Although exclusive breastfeeding is recommended for the first six months of life, research suggests that breastfeeding initiation rates and duration among Indigenous communities differ from this recommendation. Qualitative studies point to a variety of factors influencing infant feeding decisions; however, there has been no collective review of this literature published to date. Therefore, the objective of this scoping review was to identify and summarize the qualitative literature regarding Indigenous infant feeding experiences within Canada, the United States, Australia, and Aotearoa. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses- Scoping Reviews and the Joanna Briggs Institute Guidelines, in October 2020, Medline, Embase, CINAHL, PsycINFO, and Scopus were searched for relevant papers focusing on Indigenous infant feeding experiences. Screening and full-text review was completed by two independent reviewers. A grey literature search was also conducted using country-specific Google searches and targeted website searching. The protocol is registered with the Open Science Framework and published in BMJ Open. Results: Forty-six papers from the five databases and grey literature searches were included in the final review and extraction. There were 18 papers from Canada, 11 papers in the US, 9 studies in Australia and 8 studies conducted in Aotearoa. We identified the following themes describing infant feeding experiences through qualitative analysis: colonization, culture and traditionality, social perceptions, family, professional influences, environment, cultural safety, survivance, establishing breastfeeding, autonomy, infant feeding knowledge, and milk substitutes, with family and culture having the most influence on infant feeding experiences based on frequency of themes. Conclusions: This review highlights key influencers of Indigenous caregivers' infant feeding experiences, which are often situated within complex social and environmental contexts with the role of family and culture as essential in supporting caregivers. There is a need for long-term follow-up studies that partner with communities to support sustainable policy and program changes that support infant and maternal health. [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.

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]

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.

This paper studies a distributionally robust multi-item newsvendor problem, where the demand distribution is unknown but specified with a general event-wise ambiguity set. Using the event-wise affine decision rules, we can obtain a conservative approximation formulation of the problem, which can typically be further reformulated as a linear program. In order to efficiently solve the resulting large-scale linear program, we develop a column generation-based decomposition scheme and speed up the computational efficiency by exploiting a special column selection strategy and stopping early based on a Karush-Kuhn-Tucker condition test. Focusing on the Wasserstein ambiguity set and the event-wise mean absolute deviation set, a computational study demonstrates both the computational efficiency of the proposed algorithm, which significantly outperforms a commercial solver and a Benders decomposition method, and the out-of-sample superiority of distributionally robust solutions relative to their sample average approximation counterparts.

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]
