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]

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]

Introduction: This study presents a global research scenario in the broad domain of osteoarthritis (OA) research, using quantitative and qualitative publication and citation indicators. 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]

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]

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.

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.

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.

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]

This paper aims to introduce a novel family of probability distributions by the well-known method of the T–X family of distributions. The proposed family is called a "Novel Generalized Exponent Power X Family" of distributions. A three-parameters special sub-model of the proposed method is derived and named a "Novel Generalized Exponent Power Weibull" distribution (NGEP-Wei for short). For the proposed family, some statistical properties are derived including the hazard rate function, moments, moment generating function, order statistics, residual life, and reverse residual life. The well-known method of estimation, the maximum likelihood estimation method is used for estimating the model parameters. Besides, a comprehensive Monte Carlo simulation study is conducted to assess the efficacy of this estimation method. Finally, the model selection criterion such as Akaike information criterion (AINC), the correct information criterion (CINC), the Bayesian information criterion (BINC), the Hannan–Quinn information criterion (HQINC), the Cramer–von-Misses (CRMI), and the ANDA (Anderson–Darling) are used for comparison purpose. The comparison of the NGEP-Wei with other rival distributions is made by Two COVID-19 data sets. In terms of performance, we show that the proposed method outperforms the other competing methods included in this study. [ABSTRACT FROM AUTHOR]

Purpose: Research on intimate partner violence (IPV) is generally focused on female survivors. However, in Canada, about half of all self-reported victims of IPV are men and 1 in 5 calls to police for domestic violence are for male victims. This paper takes a comparative approach to understanding survivors' experiences of IPV. Methods: Across Canada, 110 female and 45 male survivors of IPV were recruited through media, social media, and listservs for a survey and interviews in 2017. Results: Findings indicate areas of similarity (healthcare needs; difficulty accessing formal support; fear of false accusations) and areas of difference (availability of formal support; types of violence experienced most often; interactions with the justice system). Women and men reported similar types of IPV, with women experiencing higher rates of sexual violence, stalking, and damage to property. Women and men reported similar physical and mental health consequences following IPV. Men were less satisfied than women with the response of the justice system, and both female and male participants encountered gender bias within the justice system. Some women reported being turned away from services that were at their maximum capacity, and men reported difficulty identifying IPV-related services for male survivors. Conclusions: Findings can be used by frontline service providers and the justice system to ensure that services are gender-inclusive and gender-sensitive. [ABSTRACT FROM AUTHOR]

Purpose : People experiencing intimate partner violence (IPV) often seek, or are referred to, specialized service providers such as shelter workers, counsellors in programs for children exposed to IPV, and facilitators for men's behaviour change programs. This paper discusses the process of collaborating with service providers and survivors across Canada to articulate the often-unrecognized knowledge and skills of IPV specialists. Methods: Work included a scoping review and analysis of 140 academic and practice papers, interviews with 62 expert service providers, eight Delphi-method surveys and over 70 hours of collaborative discussion with expert working groups of experienced service providers and survivors. Results: Areas of knowledge and skill were drafted based on the review of literature and analysis of interviews with experienced service providers, then rated in Delphi surveys, and discussed by expert working groups. Consensus was reached on the Flourishing Practice Model which identifies nine areas of capability shared across IPV specialists, as well as unique knowledge and skills used to support and collaborate with survivors, recognize and respond to infant, child and youth experiences of violence and intervene to end abusive behaviours. The "stem" recognizes the critical role of IPV specialist organizations and leaders in supporting service providers' capabilities. "Blank petals" are included to signify expertise that has not yet been documented and to recognize ongoing growth. Conclusions: The combination of methods and processes allowed for the integration of research and practice knowledge with survivor and service provider voices to gain deeper insight into the knowledge and skills of IPV specialists.

Risk prediction models hold great promise to reduce the impact of cancer in society through advanced warning of risk and improved preventative modalities. These models are evolving and becoming more complex, increasingly integrating genetic screening data and polygenic risk scores as well as calculating risk for multiple types of a disease. However, unclear regulatory compliance requirements applicable to these models raise significant legal uncertainty and new questions about the regulation of medical devices. This paper aims to address these novel regulatory questions by presenting an initial assessment of the legal status likely applicable to risk prediction models in Canada, using the CanRisk tool for breast and ovarian cancer as an exemplar. Legal analysis is supplemented with qualitative perspectives from expert stakeholders regarding the accessibility and compliance challenges of the Canadian regulatory framework. While the paper focuses on the Canadian context, it also refers to European and U.S. regulations in this domain to contrast them. Legal analysis and stakeholder perspectives highlight the need to clarify and update the Canadian regulatory framework for Software as a Medical Device as it applies to risk prediction models. Findings demonstrate how normative guidance perceived as convoluted, contradictory or overly burdensome can discourage innovation, compliance, and ultimately, implementation. This contribution aims to initiate discussion about a more optimal legal framework for risk prediction models as they continue to evolve and are increasingly integrated into landscape for public health.

This paper reviews major structural drivers of place-based health disparities in the context of Canada, an industrialized nation with a strong public health system. Likelihood that the COVID-19 pandemic will facilitate rejuvenation of Canada's northern and remote areas through remote working, advances in online teaching and learning, and the increased use of telemedicine are also examined. The paper concludes by identifying some common themes to address healthcare disparities for northern and remote Canadian residents. [ABSTRACT FROM AUTHOR]

Rates of mental health problems and disorders in children and youth have been increasing for at least three decades, and these have escalated due to the pandemic and multiple other societal stressors. It is increasingly recognized that students and families frequently struggle to receive needed care through traditional locations such as specialty mental health centers. Upstream mental health promotion and prevention strategies are gaining support as a public health approach to supporting overall population well-being, better utilizing a limited specialty workforce, and reducing illness. Based on these recognitions, there has been a progressive and escalating movement toward the delivery of mental health support to children and youth "where they are," with a prominent and more ecologically valid environment being schools. This paper will provide a brief review of the escalating mental health needs of children and youth, advantages of school mental health (SMH) programs in better meeting these needs, example model SMH programs from the United States and Canada, and national and international SMH centers/networks. We conclude with strategies for further propelling the global advancement of the SMH field through interconnected practice, policy, and research. [ABSTRACT FROM AUTHOR]

The military lifestyle can be defined by a triad of unique stressors: frequent relocation, parental absence, and risk of injury, illness and/or death of a serving member. Research has suggested that this unique triad of stressors can impact the mental health of children and youth living in military families. However, research focusing on the mental health of children and youth living in military families overwhelmingly focuses on the American context. Due to key contextual differences, it is unclear to what extent the American findings are representative of military-connected children and youth living in other geographical contexts, such as Canada. A large qualitative study was conducted to explore the mental health of military-connected children in Canada from three perspectives: child, parent, and service provider. This paper reports on the service provider findings. Using individual semi-structured interviews, data were collected from 11 service providers. Data analysis was guided by qualitative content analysis. Two main themes emerged: (1) the mental health of children living in military families may be impacted by the military lifestyle stressors, and (2) the mental health of children living in military families can be impacted by the accessibility and availability of mental health services. While this qualitative study builds upon recent Canadian work that has considered the service provider perspective, additional research is needed to better understand the experiences of service providers who support military-connected children and youth. Highlights: American research shows that the military lifestyle factors can impact the mental health of military-connected children. The mental health of military-connected children has yet to be extensively explored in Canada. The mental health of children living in Canadian military families may be impacted by the military lifestyle stressors. The mental health of Canadian military-connected children can be impacted by the accessibility and availability of mental health services. Our findings can help build capacity and knowledge for service providers who support Canadian military-connected children. [ABSTRACT FROM AUTHOR]

Agricultural activities can generate contaminants that enter underlying granular aquifers and become transported within the groundwater to adjacent streams. This paper reports on estimation of the transit time of groundwater through a saturated granular unconfined aquifer in an agricultural region of Saguenay-Lac-Saint-Jean, Quebec (Canada). A multi-technique approach is applied, integrating analytical, hydrogeochemical, and numerical methods—to determine groundwater flow from a recharge (wetland) to discharge zone (groundwater seep). Fieldwork observations, including borehole drilling, soil/groundwater sampling, and piezometers, were combined with laboratory measurements of soil hydrogeological properties and stable (δ18OH2O and δ2HH2O)/radioactive (3H) isotopes in the collected groundwater. The Dupuit–Forchheimer-based analytical method used here estimated a groundwater transit time of 7.75 years, whereas the hydrogeochemical-based and three-dimensional FEFLOW numerical method produced estimates of 7.34 and 7.27 years, respectively. The similarity of the three estimates highlights the robustness of the approach, which integrates field data to produce accurate assessments of groundwater transit time. This multi-technique approach will help in the sustainable management of groundwater resources and for preparing effective environmental plans for agricultural practices in areas underlain by aquifers.

Background: Chest low-dose computed tomography (LDCT) is a promising technology for population-based screening because it is non-invasive, relatively inexpensive, associated with low radiation and highly sensitive to lung cancer. To improve the cost-effectiveness of lung cancer screening, simultaneous screening for other diseases could be considered. This systematic review was conducted to analyse studies that published evidence on the cost-effectiveness of chest LDCT screening programs for different diseases. Methods: Scopus and PubMed were searched for English publications (1 January 2011–22 July 2022) using search terms related to screening, computed tomography and cost-effectiveness. An additional search specifically searched for the cost-effectiveness of screening for lung cancer, chronic obstructive pulmonary disease or cardiovascular disease. Included publications should present a full health economic evaluation of population screening with chest LDCT. The extracted data included the disease screened for, model type, country context of screening, inclusion of comorbidities or incidental findings, incremental costs, incremental effects and the resulting cost-effectiveness ratio amongst others. Reporting quality was assessed using the 2022 Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist. Results: The search yielded 1799 unique papers, of which 43 were included. Most papers focused on lung cancer screening (n = 40), and three were on coronary calcium scoring. Microsimulation was the most commonly applied modelling type (n = 16), followed by life table analysis (n = 10) and Markov cohort models (n = 10). Studies reflected the healthcare context of the US (n = 15), Canada (n = 4), the UK (n = 3) and 13 other countries. The reported incremental cost-effectiveness ratio ranged from US$10,000 to US$90,000/quality-adjusted life year (QALY) for lung cancer screening compared to no screening and was US$15,900/QALY–US$45,300/QALY for coronary calcium scoring compared to no screening. Discussion: Almost all health economic evaluations of LDCT screening focused on lung cancer. Literature regarding the health economic benefits of simultaneous LDCT screening for multiple diseases is absent. Most studies suggest LDCT screening is cost-effective for current and former smokers aged 55–74 with a minimum of 30 pack-years of smoking history. Consequently, more evidence on LDCT is needed to support further cost-effectiveness analyses. Preferably evidence on simultaneous screening for multiple diseases is needed, but alternatively, on single-disease screening.

This paper examines the roots of the Association for Media and Technology in Education (AMTEC) in Canada and its connections to global educational technology and media organizations including the Association for Educational Communications and Technology (AECT). The AMTEC History Project, which is preserving memories, voices and documents related to the field of educational technology in Canada, celebrates the 50th anniversary of AMTEC in the context of the 100th anniversary of AECT. Generations of AECT leaders had a substantive influence on the history of AMTEC. Interviews with memory keepers as part of this history project revealed the importance of communication, collaboration, networking, persistence, and a learning mindset for those engaged as educational technologists, as they navigated change. Students, academics, and practitioners of educational technology may benefit from lessons learned by the Canadian pioneers of multi-media instruction and research collected in this project.

Summary: Healthcare administrative (claims) data are commonly utilized to estimate drug effects. We identified considerable heterogeneity in fracture outcome definitions in a scoping review of 57 studies that estimated osteoporosis drug effects on fracture risk. Better understanding of the impact of different fracture definitions on study results is needed. Purpose: Healthcare administrative (claims) data are frequently used to estimate the real-world effects of drugs. Fracture incidence is a common outcome of osteoporosis drug studies. We aimed to describe how fractures are defined in studies that use claims data. Methods: We searched MEDLINE (Ovid), Embase (Ovid), CINAHL (EBSCO), and gray literature for studies published in English between 2000 and 2020 that estimated fracture effectiveness (hip, humerus, radius/ulna, vertebra) or safety (atypical fracture of the femur, AFF) of osteoporosis drugs using claims data in Canada and the USA. Literature searches, screening and data abstraction were completed independently by two reviewers. Results: We identified 57 eligible studies (52 effectiveness, 3 safety, 2 both). Hip fracture was the most common fracture site studied (93%), followed by humerus (66%), radius/ulna (59%), vertebra (61%), and AFF (9%). Half (n = 29) of the studies did not indicate specific data sources, codes, or cite a validation paper. Of the papers with sufficient detail, heterogeneity in fracture definitions was common. The most common definition within each fracture site was used by less than half of the studies that examined effectiveness (12 definitions in 29 hip fracture papers, 8 definitions in 17 humerus papers, 8 definitions in 13 radius/ulna papers, 9 definitions in 15 vertebra papers), and 3 definitions among 4 AFF papers. Conclusion: There is ambiguity and heterogeneity in fracture outcome definitions in studies that leverage claims data. Better transparency in outcome reporting is needed. Future exploration of how fracture definitions impact study results is warranted. [ABSTRACT FROM AUTHOR]

The proper interpretation of offers and acceptances has, despite their undisputable role in the formation of contracts, received relatively little theoretical and comparative analysis in recent years. The notorious legal question of when a contract is considered to have been formed is a fundamental concept in all legal systems, yet its nature remains poorly understood and controversial. Moreover, recent doctrinal and jurisprudential developments in English, French, US, German, and Canadian law of contracts call for further systematic assessment of this fascinating topic. This paper seeks to provide a systematic comparative evaluation of the disparate doctrines governing offer and acceptance and the consequential formation of contracts in English, US, German, French, and Canadian law of contracts. While employing well-defined normative criteria of justice and wealth-maximization, it identifies the aspects of suboptimal reliance, rent-seeking, cost-avoidance, and opportunistic revocations and provides a set of economically inspired arguments for justification of the mailbox rule. The paper is an attempt to determine how much new light the comparative analysis of law can shed on the puzzling issues of offer and acceptance so as to help clarify them. [ABSTRACT FROM AUTHOR]

In this paper we propose a machine learning-based approach to predict a multitude of insurance claim categories related to canine diseases. We introduce several machine learning approaches that are evaluated on a pet insurance dataset consisting of 785,565 dogs from the US and Canada whose insurance claims have been recorded over 17 years. 270,203 dogs with a long insurance tenure were used to train a model while the inference is applicable to all dogs in the dataset. Through this analysis we demonstrate that with this richness of data, supported by the right feature engineering, and machine learning approaches, 45 disease categories can be predicted with high accuracy.

Parenting education interventions and parenting programs are important for health promotion efforts among children and families; however, the majority of parenting programs are directed towards and attended by mothers. This is problematic because research has consistently demonstrated that fathers' active participation in the family can have a positive influence on mothers' well-being, children's self-esteem, success in school, and interpersonal relationships. In this paper, using an intersectional poststructuralist framework, document analysis, and Bacchi and Goodwin's "What's the problem represented to be" approach (WPR), we analyzed the program policies of 12 organizations that provide family-centred services in the Downtown Eastside of Vancouver, British Columbia, Canada. We identified the following three discourses: organizations strive to be client-centred and provide choices; organizations want to empower their participants; and women need safe place to raise their families. Our analysis revealed that fathers are absent or represented as problems in program policies, and that this has consequences for not only fathers but also mothers and children. Highlights: Dominant discourses of gender are upheld through the exclusion of fathers in program policies. The exclusion of fathers in policies produces them as either absent/problematic and can adversely affect families. Organizations uphold damaging discourses of masculinity that can undermine efforts to prioritize the needs of mothers. Changing language in policies may help family-centred organizations shift services and better support families. [ABSTRACT FROM AUTHOR]

Medical assistance in dying (MAiD) was legalized in Canada in 2016. Canadians' opinions on the service are nuanced, particularly as the legislation changes over time. In this paper, we outline findings from our review of representations of MAiD in Canadian news media texts since its legalization. These stories reflect the concerns, priorities, and experiences of key stakeholders and function pedagogically, shaping public opinion about MAiD. We discuss this review of Canadian news media on MAiD, provide examples of four key themes we identified (vulnerability, autonomy, dignity, and human rights), and discuss their implications for health policy and equity. Though key stakeholders share the values of autonomy, dignity, and human rights, they appeal to them in diverse ways, sometimes with conflicting policy demands. These representations offer a useful gauge of how views about MAiD continue to shift alongside changes in federal legislation. These stories can influence related policies, respond to the powerful voices that shape MAiD legislation, and have the potential to change national conversations. Our analysis adds to the existing body of scholarship on MAiD by examining post-Bill C-7 news media, identifying related health equity issues and tensions, and discussing potential impacts of MAiD's representations in news media.

Rural, remote, and northern Indigenous communities in Canada frequently face limited access to healthcare services with ongoing physician and staff shortages, inadequate infrastructure, and resource challenges. These healthcare gaps have produced significantly poorer health outcomes for people living in remote communities than those living in southern and urban regions who have timely access to care. Telehealth has played a critical role in bridging long-standing gaps in accessing healthcare services by connecting patients and providers across distance. While the adoption of telehealth in Northern Saskatchewan is growing, its initial implementation faced several barriers related to limited and stretched human and financial resources, infrastructure challenges such as unreliable broadband, and a lack of community involvement and engaged decision-making. Emerging ethical issues during the initial implementation of telehealth in community contexts have been wide ranging including concerns around privacy that have also shaped patients' experiences and particularly the need to consider place and space within rural contexts. Drawing from a qualitative study with four Northern Saskatchewan communities, this paper offers critical perspectives on the resource challenges and place-based considerations that are shaping telehealth in the Saskatchewan context and provides recommendations and lessons learned that could inform other Canadian regions and countries. This work responds to the ethics of tele-healthcare in rural communities in Canada and contributes perspectives of community-based service providers, advisors, and researchers.

Groundwater sustainability is challenged by the difference between legal and scientific understanding of groundwater, as well as the lack of focused attention to regulatory design in the literature on groundwater institutions, governance and management. The purpose of this paper is to use the scientific characteristics of groundwater to direct the necessary elements of regulatory design for this unique element. Developing interdisciplinary language that could be applied in any jurisdiction or region, the article describes seven groundwater characteristics as processes, functions, qualities, physical sustainability, scale, information and data, and physical state. Using these characteristics of groundwater embeds the scientific understanding of groundwater into regulatory design and enables the expression of new values such as Indigenous rights to water. Applying these scientific characteristics to a case study of new groundwater regulation in a subnational jurisdiction in the Global North—British Columbia (BC), Canada—highlights the failure of regulatory design even in a well-resourced jurisdiction where environmental regulation is the norm. Groundwater in BC is extremely heterogeneous in process and function, with low observation density and undefined sustainability goals where regulations are applied uniformly. Looking forward, three recommendations can be drawn using the scientific characteristics of groundwater to improve regulatory design in BC: defining sustainability goals and ecological thresholds; regionalizing and prioritizing; and long-term planning. This science-forward and interdisciplinary approach has implications for states with customary water entitlements and multiple legal orders. It also provides practitioners with an interdisciplinary language that can be useful for assessing current and future regulatory design. [ABSTRACT FROM AUTHOR]

Information-Centric Networking (ICN) is an emerging paradigm that allows users to retrieve content items securely, independently of their location. Therefore, an item may be stored in a location outside the administrative realm of its owner (e.g., cache, CDN node). In this paper, we propose a solution that allows these 3rd party storage nodes to verify that a user is authorized to access a a particular content item. We consider an SDN-based ICN deployment and we leverage Verifiable Credentials to build chains of trust, as well as to express users' capabilities. With our solution, users can prove authorization using a single message that can be integrated into a content request. Additionally, verifying entities do not have to store any secret. Our solutions support delegation, and it is lightweight. [ABSTRACT FROM AUTHOR]

This work investigates the effectiveness of solar heating using clear polyethylene bags against rice weevil Sitophilus oryzae (L.), which is one of the most destructive insect pests against many strategic grains such as wheat. In this paper, we aim at finding the key parameters that affect the control heating system against stored grain insects while ensuring that the wheat grain quality is maintained. We provide a new benchmark dataset, where the experimental and environmental data was collected based on fieldwork during the summer in Canada. We measure the effectiveness of the solution using a novel formula to describe the amortising temperature effect on rice weevil. We adopted different machine learning models to predict the effectiveness of our solution in reaching a lethal heating condition for insect pests, and hence measure the importance of the parameters. The performance of our machine learning models has been validated using a 10-fold cross-validation, showing a high accuracy of 99.5% with 99.01% recall, 100% precision and 99.5% F1-Score obtained by the Random Forest model. Our experimental study on machine learning with SHAP values as an eXplainable post-hoc model provides the best environmental conditions and parameters that have a significant effect on the disinfestation of rice weevils. Our findings suggest that there is an optimal medium-sized grain amount when using solar bags for thermal insect disinfestation under high ambient temperatures. Machine learning provides us with a versatile model for predicting the lethal temperatures that are most effective for eliminating stored grain insects inside clear plastic bags. Using this powerful technology, we can gain valuable information on the optimal conditions to eliminate these pests. Our model allows us to predict whether a certain combination of parameters will be effective in the treatment of insects using thermal control. We make our dataset publicly available under a Creative Commons Licence to encourage researchers to use it as a benchmark for their studies. [ABSTRACT FROM AUTHOR]

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

This paper discusses the experiences during COVID-19 of mothers who have young children, are survivors of domestic violence and who share parenting to highlight the further unsafe situations survivors of violence and their children were placed in during the pandemic. Part of a larger mixed methods study, these participants (n = 19) from three Canadian provinces, Alberta, Manitoba and Ontario, engaged in virtual individual one-on-one interviews via zoom. Using thematic analysis, four themes emerged from the data: 1) increased use of coercive controlling behaviors; 2) fear of the unknown; 3) lack of supports; and, 4) finding balance. Direct quotes are used to highlight the meaning of each theme. We outline the challenges these women have that are in addition to those experienced by many during COVID-19 times (increased stress, isolation, disconnect from supports, financial challenges). These include managing the shared parenting arrangements with a former abusive partner who used the pandemic as a further opportunity for coercive controlling behaviors under the guise of the public health order. The mothers were left to manage the difficult exchanges with a former abusive partner and unknown circumstances of the pandemic without guidance and support from legal actors. There will need to be a prioritization of the safety of mothers and their children in post-divorce parenting arrangements both during times of a community lockdown such as during the pandemic and also during non-pandemic times.

Many countries are experiencing an ongoing opioid crisis characterized by high rates of opioid use problems, overdose, poisoning, and death. Stigma has been identified as a central problem for seeking and receiving quality services from health providers and first respondents. The Mental Health Commission of Canada developed a scale that could be used to measure stigma in this population, as no such scale currently exists. This paper provides the results of psychometric testing of this new scale, known as the Opening Minds Provider Attitudes Towards Opioid-Use Scale (OM-PATOS), using exploratory (EFA) and confirmatory (CFA) factor analysis. EFA findings showed a 15 item 2-factor solution, with subscales of 'attitudes' (6 items) and 'behaviours/motivation to help' (9 items). The confirmatory factor analysis provided some preliminary confirmation of the factor structure suggested by the exploratory analyses, but further research with larger samples is needed to fully confirm the factor structure. Overall, results support the use of the 15-item scale with health professionals and first responders, with factors used for descriptive value rather than as calculated subscales until further research can be completed.

This paper presents the failure analysis of layered clayey slopes with emphasis on the combined effect of the clay's weakening behavior and the seismic loading using the particle finite element method (PFEM). Diverse failure mechanisms have been disclosed via the PFEM modelling when the strain-weakening behavior of clay is concerned. In contrast to a single layered slope exhibiting either a shallow or a deep failure mode, a layered slope may undergo both failure modes with a time interval in between. Seismic loadings also enlarge the scale of slope failure in clays with weakening behavior. The failure of a real layered slope (i.e. the 1988 Saint-Adelphe landslide, Canada) triggered by the Saguenay earthquake is also studied in this paper. The simulation results reveal that the choice of the strain-softening value controls the slip surface of the landslide and the amplification effect is important in the triggering of the landslide.

An intensity–duration–frequency (IDF) curve describes the relationship between rainfall intensity and duration for a given return period and location. Such curves are obtained through frequency analysis of rainfall data and commonly used in infrastructure design, flood protection, water management, and urban drainage systems. However, they are typically available only in sparse locations. Data for other sites must be interpolated as the need arises. This paper describes how extreme precipitation of several durations can be interpolated to compute IDF curves on a large, sparse domain. In the absence of local data, a reconstruction of the historical meteorology is used as a covariate for interpolating extreme precipitation characteristics. This covariate is included in a hierarchical Bayesian spatial model for extreme precipitations. This model is especially well suited for a covariate gridded structure, thereby enabling fast and precise computations. As an illustration, the methodology is used to construct IDF curves over Eastern Canada. An extensive cross-validation study shows that at locations where data are available, the proposed method generally improves on the current practice of Environment and Climate Change Canada which relies on a moment-based fit of the Gumbel extreme-value distribution.

Many sediment attributes have been proposed as proxies for determining salinity conditions under which sediment is deposited, and six attributes (Sr/Ba-HAc, Sr/Ba-NH4Ac, δ13Corg, C/N, and the relative abundances and concentrations of dinoflagellate cysts) are compared here. In this paper, sediment attributes from the Fraser River Delta, Canada and surrounding coastal areas are compared by depositional position along the fluvial-to-marine transition, by salinity, and by sedimentological characteristics. Along the fluvial-to-marine transition, most attributes exhibit distinct trends between parts of the river that experience sustained marine water (saltwater) influence over seasonal and tidal timeframes, and parts that experience only freshwater or periodic saltwater influence. No attributes are reliable indicators of depositional position where saltwater incursion is short lived or where water is fresh. Where marine influence is sustained, Sr/Ba-HAc and Sr/Ba-NH4Ac are the most reliable positional indicators along the fluvial-to-marine transition. When compared strictly to salinity, Sr/Ba-HAc, Sr/Ba-NH4Ac, and δ13Corg all correlate predictably except in delta front and prodelta settings. Our data show that all six sediment attributes are heavily impacted by river-derived sedimentation, and it is not appropriate to compare values from strongly river-influenced settings (e.g., deltas) with those from weakly river-influenced settings (e.g., bays and estuaries).

In rural, remote, and northern parts of Canada, the pre-existing vulnerability and risk for intimate partner violence has been exacerbated by COVID-19. The purpose of this commentary is to identify the unique impact of COVID-19 on intimate partner violence both in terms of the bearing on those experiencing abuse and on the service sector in rural, remote and northern communities where the rates of intimate partner violence and intimate partner femicide pre-pandemic are higher than in larger cities. The recommendations offered in this paper include enhanced safety planning, alternate housing for victims fleeing violence, and suggestions for service providers. We also offer ways to move forward with further research in the COVID-19 era. [ABSTRACT FROM AUTHOR]

Purpose: Social adversity experiences have increased during the pandemic and are potential risk factors for both depression and support for violent radicalization (VR). However, the cumulative and independent effects of various social adversity experiences on support for VR have yet to be explored. This paper examines the cumulative and independent effects of COVID- and non-COVID-related discrimination, exposure to violence, traditional and cyberbullying victimization on support for VR. In addition, we investigate whether depression mediates the relationship between these forms of social adversity and support for VR. Methods: A total of 6003 young adults (Mage = 27, SDage = 4.40, range 18–35) living in metropolitan areas in Canada responded to an online survey. We used multivariable regression models, controlling for socio-demographic characteristics, to infer covariate adjusted associations between social adversity measures and support for VR. Additionally, we conducted a formal mediation analysis to estimate the proportion mediated by depression. Results: There was a cumulative relationship between experiences of social adversity and support for VR (β = 1.52; 95% CI: 1.32, 1.72). COVID-related discrimination and cyberbullying victimization were independently associated with stronger support for VR. Depression partially mediated the effect of cumulative social adversity, COVID-related discrimination and cyberbullying on support for VR. Conclusion: Prevention programs during the present pandemic should prioritize decreasing discrimination and providing psychosocial support to depressed young adults who experience social adversity. Practitioners should prioritize developing programs that foster digital literacy skills and critical thinking among young adults to address the concerning impact of cyberbullying on support for VR.

In the last three decades, Canadian universities have grown in size and complexity and undergone deep transformations. Meanwhile, who should be appointed as highest-ranking administrative officers and what they ought to be doing once appointed has remained hotly debated. This paper examines how Canadian universities' understanding and framing of their presidents and provosts in job advertisements has changed over this last thirty-year period. Our study analysed 153 job advertisements published between 1987 and 2017 to determine how these positions were portrayed over time. The analysis relied on a conceptualization of academic administration as a combination of scholarship, management, and leadership roles. Overall, the findings show an important shift in the symbolic language used to describe these positions, shifts which appear to be linked to Canadian universities' increasing use of recruiting firms. Presidents, first depicted as respected scholars, are now portrayed as charismatic heroes, while depictions of provosts have remained largely stable, focusing on their administrative support roles. Overall, the findings suggest that popular, if unrealistic, heroic depictions of Canadian university senior administrators are becoming prevalent in the crafting of job advertisements. Recognizing how these in turn shape how stakeholders understand these positions, greater attention should be given to the crafting of these key role signals. [ABSTRACT FROM AUTHOR]

This paper presents a direct platform-to-platform comparison of ground, helicopter, and unmanned aircraft system (UAS) magnetic data acquired over a 4.96 km2 prospective gold area in the Abitibi Greenstone Belt of the Canadian Precambrian Shield. Qualitative comparison focused on visual inspection of residual and gradient magnetic maps, focusing mainly on features associated with iron formations. Quantitative comparison employed maps of cell-by-cell absolute difference, percent difference, and coherence, as well as three global image similarity parameters: the structural similarity index, the mean squared error, and the peak signal-to-noise ratio. The qualitative comparison revealed that lateral continuity along the dominant E–W structural geological trend was better captured in the ground and UAS data than in the helicopter data. The UAS data had the additional advantage over the ground data of having undergone minimal processing. The quantitative comparison metrics were the same between all three datasets. This study showed that UAS technology is delivering the same data quality as traditional survey techniques in addition being an attractive economic and safety choice. [ABSTRACT FROM AUTHOR]

Determining the threshold separating poor from non-poor populations is one of the most influential choices when measuring poverty. Commonly used selection criteria leave considerable room for discretion or are not appropriate as academic standards. This vacuum in academic guidance leads to arbitrary and/or ideologically driven choices. This can greatly influence the measurement of a societal phenomenon, and thus research and public policy decisions over a period that extends well beyond the mandate of those making that threshold decision. This paper sets out an empirical validation method that contributes to reducing the range of thresholds and thereby aids decision-makers in making that normative decision. Our method uses an absolute concept of empirical validity and requires that the microdata for measuring poverty hold additional information closely associated with poverty. The method builds on insights from theory on measurement error that, for any given threshold, some persons are wrongly identified as poor (false positives) and others are wrongly identified as not poor (false negatives), and that the reduction of one error can only be attained by increasing the other. Our method uses the additional microdata to disaggregate the population into (likely) false positives and (likely) false negatives and analyzes marginal changes in this composition as the poverty threshold becomes stricter. Using Canadian data, we show that this approach substantially narrows the range of thresholds for two unidimensional poverty indicators, namely a material deprivation and an income poverty indicator. The underlying principle of the method extends to other (unidimensional) social indicators. The analysis itself can also serve other purposes, such as deepening our understanding of poverty and the cost-effectiveness of policies to reduce it. [ABSTRACT FROM AUTHOR]

Purpose: The Seattle Angina Questionnaire (SAQ) is a widely used patient-reported measure of health status in patients with coronary artery disease. Comparisons of SAQ scores amongst population groups and over time rely on the assumption that its factorial structure is invariant. This study evaluates the measurement invariance of the SAQ across different demographic and clinical groups and over time. Methods: Data were obtained from the Alberta Provincial Project on Outcome Assessment in Coronary Heart Disease registry, a registry of patients who received coronary angiogram in Alberta, Canada. The study cohort consists of adult patients who completed the paper-based version of the 16-item Canadian version of the SAQ (SAQ-CAN) 2 weeks and 1-year post-coronary angiogram between 2009 and 2016. Multi-group confirmatory factor analysis was used to assess configural, weak, strong, and strict measurement invariance across age groups, sex, angina type, treatment, and over time. Model fit was assessed using the comparative fit index and root mean square error of approximation. Results: Of the 8101 patients included in these analysis, 1300 (16.1%) were at least 75 years old, while 1755 (21.7%) were female, 5154 (63.6%) were diagnosed with acute coronary syndrome, 1177 (14.5%) received coronary artery bypass graft treatment, and 3279 had complete data on the SAQ-CAN at both occasions. There was evidence of strict invariance across age, sex, and angina type, and treatment groups, but partial strict invariance was established over time. Conclusion: SAQ-CAN can be used to compare the health status of coronary artery disease patients across population groups and over time. [ABSTRACT FROM AUTHOR]

The mining industry, considered a traditional and conservative industry with respect to innovation, finds itself at a turning point due to the increasingly complex challenges, such as declining ore grades. These challenges have created an imperative to innovate. Parallel to the above, several digital innovations are being implemented in many mining operations across the globe. Not only do these provide solutions to the existing problems but also radically transform mining processes, increasing efficiency, profitability, and the ability to comply with stricter regulations. The incorporation of mature and incipient technologies into the mining industry has opened up many opportunities for long-established firms as well as knowledge-based start-ups. This includes potential suppliers in countries where mining accounts for a significant share of the GDP but the development of productive linkages remains suboptimal, as in Latin American countries. While in recent years, some suppliers in Latin America have made important contributions to increasing innovation in the mining industry, most suppliers in the region have not been able to do so. This paper provides an overview of the innovation paradigm of the mining sector from a global perspective, i.e., how innovation processes take place in countries with a long-established technological leadership in the mining sector, such as Australia and Canada. Given the importance of suppliers in this process, a special attention is paid to innovation in various stages of the supply chain. This is in order to provide a departure point for identifying windows of opportunity for equipment and service suppliers in Latin America. [ABSTRACT FROM AUTHOR]

The association between religion and health has been the subject of growing interest in academia. However, limited reviews of such studies in Canada exist. The paper systematically reviews and synthesizes existing literature on the relationship between spirituality and health in Canada. Available general databases such as: Medline; Web of Science, PubMed, Sociological abstract, Social Service Abstracts, Google scholar, Humanities International Index, JSTOR, CPI.Q Canadian Periodicals, and American Theological Library Association were searched for the period between 2000 and April 2019 inclusive. Collected data were then systematically analysed for common themes about spirituality and health in Canada. In total, 151 articles were found, but only 128 had relevance with the study objectives. Overall, the analysis showed that religion and spirituality do influence health behaviours, and well-being. However, more gender-based studies need to be conducted to tease out the differences in religion/spirituality and health across different genders, and ethnic groups in Canada. [ABSTRACT FROM AUTHOR]

With the outbreak of COVID-19 pandemic in 2020, teaching online became a norm for universities in Canada. Besides the challenges of teaching topics that may be impossible to be taught online, a major issue that the mandatory physical distancing brought is the relationality between teachers and students. In order to investigate how educators were making sense of such changes, semi-structured interviews were conducted with 12 education professors across Canada. In light of Derrida's and Ruitenberg's ethic of hospitality, this paper explores how the abrupt shift to online education unveiled the nature and challenges of hospitable education, especially in the online context. The implications of online instruction to professors' relationality, however, are also instrumental in illuminating the complexities and ambiguities of a teacher's responsibility even in what could be considered the "normal circumstances" of face-to-face instruction.

Objectives: Human milk expression has become an increasingly common means for providing milk to an infant, with women expressing to address breastfeeding problems or to allow for flexible feeding options. This study explored the experiences and recommendations of mothers who expressed human milk, with this paper reporting on the advice mothers would offer to other mothers to address common challenges. Methods: Interpretive description was used in this qualitative project. Using purposive sampling, mothers of infants aged 0–24 months who expressed human milk were recruited to participate from two health regions in western Canada. Individual, audio-taped interviews were completed with 35 women. NVIVO™ software was used for data analysis. Results: Mothers reported the desire to offer experiential advice to other mothers navigating milk expression and encouraged other mothers to seek guidance from health care professionals such as lactation consultants, peer support online, and from family and friends. Experiential knowledge shared included: (a) product recommendations, (b) expression tips, (c) support for workplace expression, (d) encouragement to seek help, and (e) moral support. Conclusions: Healthcare professionals should include evidence-based expression information as part of routine lactation support, while recognizing the importance of mother-to-mother knowledge transfer and emotional support. Services that assist mothers to determine and access pumps appropriate to their unique breastfeeding needs and goals should be offered, and the opportunity for peer support through creation of, or referral to, appropriate in-person or online support groups should be made available.

Hydropeaking refers to the mode of hydropower dam operation where sub-daily changes in flow are used to vary the generation of electricity in accordance with demand. A typical pattern produces maximum power during the day (i.e., the peak), and minimal power at night. Hydropeaking is considered necessary to stabilize the energy grid since it is the only reliably flexible method of producing electricity besides fossil fuels. With the planned phase-out of traditional coal-fired electricity production across Canada by 2030, and the increased reliance on intermittent wind and solar generation, the flexibility of hydropeaking will assume an increased importance. However, hydropower generation comes with costs; hydropeaking in particular is considered one of the most ecologically harmful modes of operation since downstream biota are subjected to flows that deviate greatly from typical natural flow regime patterns. The ecological effects of hydropeaking have been examined in a growing body of literature, but mitigation options do exist that include dam operational and/or structural modifications. This paper will explore the importance of hydropeaking in the Canadian electricity system, the ecological consequences of flexible hydropower, and mitigation options that could potentially strike a balance between meeting Canadian energy needs and minimizing ecosystem impacts.

Sustainable global energy production is back-stopped by hydropower which is responsible for a significant share of the green energy produced worldwide. Hydropower, however, does not come without some environmental impacts but has worked to reduce those impacts. Here, we discuss the historical, legislative, and design configurations of hydropower facilities located in three of the world's most important producers: Brazil, Canada, and Norway. The background is intended to inform the collection of scientific papers from each country aimed at assessing and improving the sustainability of hydropower production that form the core of this special issue on sustainable hydropower. We review the development and key legislative history for hydropower in each country and point out the common backgrounds and interests each nation has in the continued sustainable development of its hydropower resources.

Introduction: The lack of attention to transgender and gender diverse (TGD) people in undergraduate medical education (UME) is a point of concern, particularly among medical students. A project was undertaken to develop a UME curriculum framework for teaching the healthcare needs of TGD people. Methods: Using a modified Delphi methodology, four rounds of surveys were presented to an expert stakeholder group that included content experts, generalist physicians, UME teaching faculty, and medical students. Questions covered what content should be taught, who should teach the content, and how much time should be dedicated for this teaching. Once the Delphi process was complete, feedback on the provisional framework was sought from members of the TGD community to ensure it represented their needs and perspectives. Results: 71 panel members and 56 community members participated in the study. Core values included the scope of the framework, and topics such as inclusivity, and safety in practice and in teaching. The framework included terminology, epidemiology, medical and surgical treatment, mental health, sexual and reproductive health, and routine primary care. There was also guidance on who should teach, time to be allocated, and the learning environment. Discussion: There is a clear need to train tomorrow's doctors to provide competent and respectful healthcare services to and for TGD patients. Although local factors will likely shape the way in which this framework will be implemented in different contexts, this paper outlines a core UME-level curriculum framework for Canada and, potentially, for use in other parts of the world.

Logging causes changes in habitat structure, which can potentially lead to variations in taxonomic and functional richness of biodiversity. Studies on how functional traits in birds are affected by logging operations can provide an important element for the understanding of ecosystem processes. In this paper, we examined how logging in subtropical Andean forests influenced taxonomic and functional diversity of cavity-nesting birds. We used these results to compare how logging affected ecosystem functions in temperate and subtropical forests of the Americas. We used point-counts to examine the effects of logging on taxonomic and functional traits in avian communities (Functional Richness, Functional evenness, Functional Divergence, and Community-weighted mean). We found that logging changed bird richness and abundance, although it had no effect on the functional response to the measured traits. The comparison of our results with those of temperate forests of Canada and Chile reveals differences in the functional richness of birds in these habitats, with a lower impact of logging on functional traits. We highlight the importance of including functional traits in the analyses, since the reduction in the species richness and abundance may not be translated into functional changes within the ecosystem.

This paper examines the role of forests in national climate policies of two countries very rich in woods: Russia and Canada. Canada has made efforts to reduce direct CO2 emissions in the national economy, intensify forestry, and increase greenhouse gas sequestration by forests. Russia focuses on the verification and recalculation of the carbon sequestration capacity of its forests. Analysis of the Russian and Canadian stationary models used to assess the carbon sequestration capacity of forests (ROBUL and CBM-CFS, respectively) shows that both the Canadian model and the Russian one derived from it reflect the stationary dynamics of forest stands, which inevitably results in a downward CO2 absorption trend. Even if the forest inventory is updated on a regular basis, the predictive components of such models are unable to take into account the variability of forest ecosystems and their adaptation to climate change. Models that describe global carbon fluxes (e.g., ones using FLUXNET and remote sensing data) provide significantly higher net carbon sequestration values and indicate a nondecreasing net carbon accumulation trend in forests. It is concluded that stationary and remote sensing models should be used together to assess net carbon sequestration and formulate key principles of national climate policies in countries rich in forests.

This paper provides a narrative review of the existing literature on differences in demographic and biological features of breast cancer at time of diagnosis between Black and White women in Canada, the United Kingdom and the United States. Electronic database searches for published peer-reviewed articles on this topic were conducted, and 78 articles were included in the final narrative review. Differences between Black and White women were compared for eight categories including age, tumour stage, size, grade, lymph node involvement, and hormone status. Black women were significantly more likely to present with less favourable tumour features at the time of diagnosis than White women. Significant differences were reported in age at diagnosis, tumour stage, size, grade and hormone status, particularly triple negative breast cancer. Limitations on the generalizability of the review findings are discussed, as well as the implications of these findings on future research, especially within the Canadian context.

This paper analyzes the structures and trends of the establishment, growth, and transformation of the Jewish presence in the Americas. After outlining several fundamental characteristics of the general continental societal environment and its internal differentiation, we critically discuss several theoretical approaches to a comparative assessment of the Jewish experience. Conceptual formulations include globalization, diaspora studies, and transnationalism, aiming to highlight their achievements and drawbacks. Selected sociohistorical aspects relevant to the development of Jewish immigration, settlement, and community formation are analyzed. This is followed by the exploration of more recent patterns, outlining emerging configurations and challenges. The article focuses on the differences and commonalities between the North (United States and Canada) and the diverse Latin American experiences. The conceptual referents imply rethinking the relationship between societies, communities, individuals, territories, and sociopolitical spaces along the changing contours of dispersion. Lessons from the past may help outline future paths. [ABSTRACT FROM AUTHOR]
