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]

The recent introduction of new vaccines into the school-based immunization program in British Columbia (BC) included monitoring of adverse events following immunization (AEFI) for these new vaccines. This commentary discusses different methods used to collect AEFIs in school immunization campaigns and the effects on response rate. The results of a study using an internet-based tool inspired this paper. The study examined adverse events following human papillomavirus (HPV) vaccine given to grades 6 and 9 students. The low response rate of the internet survey resulted in insufficient findings regarding adverse events. Consequent to the analysis of the study's data, a literature review was conducted to examine survey methodologies used to collect adverse event data following school-based immunization of adolescents. A PubMed search used various combinations of the following terms: vaccine, immunization, immunization programs, reactogenicity, adverse reactions, safety, adolescent, schoolchildren, and survey. Potentially relevant papers were identified based upon the titles and abstracts and subsequently reviewed. Only four studies were deemed appropriate for comparison purposes: all were done in Canada.

Goal and Background. The LCA methodology is used to compare the potential environmental benefits of an emerging bio- technology, enzyme-bleaching, with those of elemental chlorine free (ECF) bleaching, an existing technology that is widely used in paper making. Through the use of biodegradable enzymes to supplement, or eventually to replace, chemicals in the bleaching process to extract lignin, enzyme bleaching processes are aimed to reduce the use of chlorine based bleaching chemicals and to achieve cost savings by circumventing investment into oxygen delignification or ozone bleaching technology. Scope and Method. The assessment is conducted using SimaPro 4.0 and focuses on the processes within the bleach plant stage. For this study, ECF is replaced by enzyme bleaching only in the first stage of the bleaching process. Because this is a comparative study, all upstream and downstream processes are excluded. The impact categories based on Eco-indicator 95 are used to characterize the inventory data in this study. Other methodologies, such as Eco-indicator 99 and CML 2000, have not been chosen as they are more region-specific and are not yet fully applicable to the Canadian environmental condition. A new initiative to develop a Canadian Life Cycle Impact Assessment (LCJA) Method is ongoing at the Interuniversity Reference Center for the Life Cycle Assessment, Interpretation and Management of Products, Processes and Services (CIRAIG), Ecole Polytechnique, Canada. Results and Conclusion. The analysis shows that the introduction of enzyme bleaching into the ECF process significantly im- proves the overall environmental performance in the majority of the impact categories. Extending the substitution of enzyme bleaching for chlorine dioxide is warranted. Of the three im- pact categories where increased impact was noted, two of these which increased emissions of greenhouse gases and increased incidence of summer smog, would be completely eliminated if the enzyme mediator was manufactured at the point of use. There remains a potential for increased impact from eutrophication, which would need to be managed. Recommendations and Outlook. With the only partial substitution of ECF by enzyme bleaching examined here, chlorine dioxide consumption, energy consumption, NaOH consumption, and transportation remain the key hot spots and warrant further research. Anything that can be done to replace or reduce chlorine dioxide consumption will benefit the environment. [ABSTRACT FROM AUTHOR]

The article focuses on the factors influencing the 7-ethoxyresorufin-o-deethylase (EROD) activity in Feral Winter Flounder which was exposed to effluent from a pulp and paper mill in Newfoundland, Canada. Aquatic organisms can biotransform organic chemicals by producing a series of enzymes which include the mixed function oxygenase (MFO) system. Effluent discharged by pulp and paper mills have been reported to induce MFO activity in a number of fish species. Winter flounder were captured at depths of 5 to 10 m by SCUBA divers. Results showed that EROD activity varied depending on water temperature, gender, sexual maturity and site of sampling in feral winter flounder inhabiting the fjord receiving effluent from the pulp and paper mill.

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.

The present study first describes the variations in concentrations of 12 chemical elements in groundwater relative to salinity levels in Southern Quebec (Canada) groundwater systems, and then uses this data to develop an empirical predictive model for evaluating groundwater chemical composition relative to salinity levels. Data is drawn from a large groundwater chemistry database containing 2608 samples. Eight salinity classes were established from lowest to highest chloride (Cl) concentrations. Graphical analyses were applied to describe variations in major, minor, and trace element concentrations relative to salinity levels. Results show that the major elements were found to be dominant in the lower salinity classes, whereas Cl becomes dominant at the highest salinity classes. For each of the major elements, a transitional state was identified between domination of the major elements and domination of Cl. This transition occurred at a different level of salinity for each of the major elements. Except for Si, the minor elements Ba, B, and Sr generally increase relative to the increase of Cl. The highest Mn concentrations were found to be associated with only the highest levels of Cl, whereas F was observed to be more abundant than Mn. Based on this analysis of the data, a correlation table was established between salinity level and concentrations of the chemical constituents. We thus propose a predictive empirical model, identifying a profile of the chemical composition of groundwater relative to salinity levels, to help homeowners and groundwater managers evaluate groundwater quality before resorting to laborious and costly laboratory analyses.

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.

The environmental benefits of water table management (WTM), as a method to reduce nitrate pollution, are well known. However, there are few published studies on the effects of WTM on water use efficiency (WUE). This paper highlights the agronomic interest of WTM for increasing WUE of irrigated grain corn production. A field study was conducted in 2001 and 2002 at a large scale WTM research facility in Québec, Canada. The region experienced periods of drought during the two growing seasons. This study shows that, by keeping the water table at 0.80 m below the soil surface, there were on average 35% increases in grain corn yields, compared to conventional free drainage. The WUEs obtained with WTM (5.1 kg m−3 in 2001 and 7.1 kg m−3 in 2002) indicate that the method is generally more water efficient than conventional sprinkler and furrow irrigation. The WUE of WTM also compares well with that of water conservation methods such as alternate furrow irrigation and deficit sprinkler irrigation. Moreover, WTM requires low inputs in terms of equipment, energy, and labour, because it makes use of existing subsurface drainage systems, which are widespread in Eastern Canada due to the region's soils and climate, and because of its design, which does not necessitate high-pressure pumps and allows for automated management. Hence, WTM appears to be an interesting alternative to conventional irrigation methods due to its combined environmental and agronomical benefits. [ABSTRACT FROM AUTHOR]

The article discusses polarization and middle class. It references the 1992 article "Polarization and the Decline of the Middle Class: Canada and the U.S.," by James Foster and Michael Wolfson in the same issue. The authors used Lorenz curve to determine pay inequality and Gini-like index to measure bipolarization. It is said that the authors' concept of polarization was divided between people with incomes below and above the median income.

In Canada, Environmental Effects Monitoring (EEM) programs exist within two regulations: the Pulp and Paper Effluent Regulations and the new Metal Mining Effluent Regulations under the Canadian Fisheries Act. EEM provides a biological, effects-based feedback loop to assess the effectiveness of technology-based regulations in protecting receiving environments. The promulgation of the Pulp and Paper Effluent Regulations, in 1992, represented a significant step forward in the Canadian regulatory approach by incorporating directly into a regulation a requirement to assess the effects of effluent discharges on receiving environments using proven scientific monitoring methodologies. Similarly, an assessment of the aquatic impacts of mines resulted in recommendations to amend the Metal Mining Effluent Regulations, recently promulgated in 2002, and includes an EEM program as a science-based feedback loop. As such, these regulations recognize the possibility that national, technology-based standards may not necessarily protect all receiving environments because of the diversity and variability of both discharges and receiving sites across the country. Since that time, EEM has improved its flexibility by considering both advances in science and the uniqueness of monitoring sites across Canada to allow the most appropriate and cost-effective monitoring approaches at each site while maintaining national consistency. This paper discusses the use of monitoring under two Canadian regulations to assess effects on aquatic ecosystems. As well, the National EEM approach to maintaining up-to-date scientific practices in a national regulatory program is discussed using examples. [ABSTRACT FROM AUTHOR]

The social distancing imposed by the Covid-19 pandemic accelerated the digitalisation of societies, which also influenced habits related to the consumption and dissemination of news. In this context, older individuals are often blamed for contributing to disinformation, which is associated with the echo chambers fostered by social media. Mass media, social media and personal communication tools act as mass, social or personal intermediaries when it comes to keeping up to date with the news. This paper analyses the preferred intermediaries of older online adults (aged 60 and over) for following the news and how they change over time. We analysed two waves of an online survey-based longitudinal study conducted in Canada and Spain, before Covid-19 pandemic (2016/17), and during Covid-19 (in 2020). We found that most participants exclusively use mass intermediaries or combine mass with social and personal intermediaries to keep abreast of the news. However, only 28% of respondents inform themselves exclusively through the alleged echo chambers of social and personal intermediaries. Results also show that media ecologies evolve in different directions, and, despite the forced digitalisation driven by the pandemic, digital media usage did not always increase or evolve towards newer technologies. This paper contributes to understanding the diverse intermediaries used by older adults to obtain news and how such media ecologies can contribute to contrasting different sources of information beyond the alleged echo chambers of social media.

Objectives: Statistics Canada administers the Agricultural Census every 5 years, and this paper presents unsuppressed data from the 2016 and 2021 Census. The data set encompasses detailed information on farm types, sizes, technology choices, and a demographic profile of farm operators from the 2021 Census. Data on farm characteristics and operator demographics is crucial for understanding innovation in agriculture and formulating evidence-based policies. Data description: The data sets cover the two most recent agriculture censuses of 2016 and 2021, presenting data on the number of farmers by region, farm type, size, and the adoption of technologies. Additionally, a third data set lists the number of farm operators by age and sex. The census questionnaire inquires about using different technologies, varying the types across the two census periods. Notably, there is no data suppression in these data sets, and they cover all 10 provinces in Canada, excluding the three territories. Farm types are categorized based on the North American Industry Classification System (NAICS), and farm size is measured in acres. [ABSTRACT FROM AUTHOR]

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.

This paper represents one of the first critical social science interrogations of an agrifood just-in-case transition. The just-in-case transition speaks to a philosophy that values building buffers and flexibility into longer value chains to make them more resilient to shocks, which stands in contrast to the just-in-time philosophy with its emphasis on long, specialized, and often inflexible networks. Influenced by COVID-related disruptions and climate change induced uncertainties, the just-in-case transition examined here centers on the heightened interest in vertical farm-anchored supply chains. Interviewing actors responsible for promoting vertical farm-anchored local supply chains in the US and Canada, I attempt to sketch out how these spaces, infrastructures, and practices care. Put differently, as understood through a feminist ethics of care, whom and what are cared for and how is care practiced in these just-in-case transitions and why? Enumerative politics was observed in the data—the idea that we can make care count. Practices and discourses linked to infrastructural/supply chain transitions are highlighted that result in care being narrowly conceived as a technical or transactional matter. The paper concludes reflecting on what it means to afford just-in-case agrifood transitions animated by matters of care that hold greater emancipatory potentials. [ABSTRACT FROM AUTHOR]

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]

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]

The Canadian Environmental Assessment Act (CEAA) defines the federal environmental assessment (EA) process for evaluating the likelihood that development projects (e.g., roads, buildings, factories) will have impacts on the environment. Environmental effects monitoring (EEM) programs for mining and pulp and paper mills under the Federal Fisheries Act, define the process that is to be used to evaluate existing effects caused by liquid effluents discharged by operating facilities. The EA process occurs before a project is approved, and involves predicting whether the project is going to cause significant environmental impacts. The EEM process occurs after a project is operational, and involves determining whether an existing project has had or is continuing to have significant impacts on the environment. Ideally, the processes are complimentary, with the EA process identifying environmental attributes considered important, and the EEM process demonstrating whether predicted or unpredicted impacts occurred. The two processes are usually done in isolation so potential synergies are lost. The point of this manuscript is to justify bridging the two processes. We use the aquatic environment as the example, and briefly describe the EEM process, aquatic environment indicators, experimental designs, and typical environmental thresholds, to illustrate how the EEM and EA processes link.

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]

Reports that food supply and contaminants were investigated as possible causes of low bald eagle productivity near a bleached kraft pulp and paper mill at Crofton on Vancouver Island, British Columbia. Details of the study which was conducted over a seven year period, which found the average productivity of five eagle territories situated south of the pulp mill at Crofton was significantly lower than six territories north of the mill.

A model of the North American pulp and paper Industry developed previously by the authors was used to simulate the trade of wood pulp between various regions of Canada and the United States, to the year 2000, under three different scenarios. The base simulation assumed no change in trade policies or cost competitiveness between regions, concentrating on the effects of changes in population and income. Under these assumptions, it was found that Canadian exports to the United States would remain approximately constant until 1990, but then double by the year 2000, reaching 5 million tons per year. Meanwhile, exports to the rest of the world would decline by 40 percent, to 2.5 million tons. Total Canadian exports would increase by some 15 percent over the next 20 years. In the second set of simulations, an ad valorem tariff on Canadian pulp was assumed. This led to a sharp reduction in U.S. imports. However, this decrease of Canadian exports to the United States would be compensated to a large extent by increased Canadian exports to Western Europe. The third simulation assumed a sustained rise in manufacturing costs for the entire pulp and paper sector in Canada. This resulted, unexpectedly, to a rise in exports of pulp to the United States. The reason was a rise In paper and newsprint production in the United States that made it advantageous for U.S. producers to import more Canadian chemical pulp. [ABSTRACT FROM AUTHOR]

This paper is an examination of the way mathematics, and STEM, arises through stories of teaching and learning on, with, and alongside Land. It emerges from research, undertaken in different Nations (Cree, Dene, Métis, Mi'kmaw, Naskapi, Canada), that considers what locally meaningful K-12 STEM teaching and learning might look like in Indigenous contexts. The paper reflects our research process. Each story is followed by a conversation that surfaces elements of how mathematics, language, learning, and different ways of knowing, being, and doing circulate together and emerge in relation to Land and all relations living within it. We frame the work in ethical relationality to open a space where Indigenous and Western knowledges might co-exist, attending to ongoing tensions in the work between ways of knowing, being, and doing of different people and peoples/nations, between perspectives and experiences of indigenous and non-indigenous participants, between languages, while still creating spaces where we might move closer together through iterative processes of collective learning. This exploration provides insight into how and when we might remember that mathematics has spirit, how quantity and pattern live in various contexts, when numbers might be inadequate for a context, and how all these ideas can meaningfully inform mathematics teaching and learning via relationships between language, mathematics and learners. We seek a mathematics that resists abstraction as extraction and instead lives and enspirits teaching and learning through relationships. [ABSTRACT FROM AUTHOR]

This paper examines two distinct corporate theories, shareholder primacy and entity theory, as foundations of corporate governance and their implications for corporate sustainability. Specifically, the purpose of this paper is to argue for a shift in perspective away from shareholder primacy towards an alternative approach—entity theory. It considers why shareholder primacy as a foundation for governance is problematic for facilitating sustainable business decisions and suggests that conceptualizing the company as an entity would provide a more appropriate theoretical foundation for governance which lends itself to sustainable corporate conduct. Although abstract in isolation, such corporate theories can have real world influence on governance and subsequently director behavior. This point is illustrated by contrasting the extent to which directors, as part of their duty to act in good faith in the best interests of the company, can factor sustainability interests into their business decisions across a shareholder orientated jurisdiction, the United Kingdom, and an entity orientated jurisdiction, Canada. The analysis demonstrates the implications of entity theory for sustainable director decisions when acting in the best interests of the company; namely, a reduction of the pressures associated with the shareholder primacy drive, broader notions of what constitutes corporate interest, and a recognition of the entity's role in society to behave as a good corporate citizen.

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]

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]

This paper introduces the MinCan database that presents mine-level estimates for the Canadian mining industry with a persistent annual coverage between 1950 and 2022. These estimates are based on archival maps and a selection of historical sources, which follows a hierarchy of criteria-based credibility and standardization. The information contained in MinCan covers 947 mines and provides information about their location (longitude and latitude in decimal), the company ownership, the principal commodities produced, and the years of operation (opening and closing dates). It is the first open access database to propose an exhaustive, free, and reliable compilation of the principal past and present mines producing in Canada. The geographic coordinates enable matching with other local, regional, and national databases, and allow for a wide range of research objectives to be met. [ABSTRACT FROM AUTHOR]

There is an expectation that health professions schools respond to priority societal health needs. This expectation is largely based on the underlying assumption that schools are aware of the priority needs in their communities. This paper demonstrates how open-access, pan-national health data can be used to create a reliable health index to assist schools in identifying societal needs and advance social accountability in health professions education. Using open-access data, a psychometric evaluation was conducted to examine the reliability and validity of the Canadian Health Indicators Framework (CHIF) conceptual model. A non-linear confirmatory factor analysis (CFA) on 67 health indicators, at the health-region level (n = 97) was used to assess the model fit of the hypothesized 10-factor model. Reliability analysis using McDonald's Omega were conducted, followed by Pearson's correlation coefficients. Findings from the non-linear CFA rejected the original conceptual model structure of the CHIF. Exploratory post hoc analyses were conducted using modification indices and parameter constraints to improve model fit. A final 5-factor multidimensional model demonstrated superior fit, reducing the number of indicators from 67 to 32. The 5-factors included: Health Conditions (8-indicators); Health Functions (6-indicators); Deaths (5-indicators); Non-Medical Health Determinants (7-indicators); and Community & Health System Characteristics (6-indicators). All factor loadings were statistically significant (p < 0.001) and demonstrated excellent internal consistency (ω >0.95). Many schools struggle to identify and measure socially accountable outcomes. The process highlighted in this paper and the indices developed serve as starting points to allow schools to leverage open-access data as an initial step in identifying societal needs.

Our paper, "The Insignificance of Thresholds in Environmental Impact Assessment: An Illustrative Case Study in Canada" received a critique that challenged us on a number of grounds. Namely, that we defame EIA practitioners, that we advocate EIAs to become a scientific enterprise, that we do not recognize the complexity inherent in EIA, and that EIA undergo an independent assessment by regulators. We respond to all of these points, and argue that conflict of interest is an institutional issue (not one of corrupt practitioners), and that we critique the science that forms the basis of evidence in EIA. Further, we show that the complexity and uncertainty in the critique cannot explain the findings from our paper that all cases of impact threshold exceedance were determined to be not significant in EIA. Finally, we compare the significance determinations in proponent reports to final regulator decisions and determine that they are overwhelmingly identical (93–95%). Regulators are financially independent of proponents, but their decisions on significant are heavily dependent on the information and analysis provided by the proponent reports. As regulators rely on these reports, environmental impact assessments must be based on rigorous and transparent analysis. [ABSTRACT FROM AUTHOR]

In Canada, low-grade ore mines generate large amounts of mineral waste, such as mine tailings. To control erosion of the fine-grained tailings particles as quickly as possible, it is common practice for the mining industry to revegetate the mine tailings with agronomic herbaceous plants. However, it is unclear whether this practice is consequential to the natural establishment of boreal species. The first objective of this study was to evaluate which families of agronomic herbaceous plants (legumes or grasses) result in the most favorable physical and chemical soil properties for the establishment of boreal species. The second objective was to determine the effect of the agronomic herbaceous plants on the growth and foliar nutrient concentration on three indigenous boreal forest seedlings; jack pine (Pinus banksiana Lambert), tamarack (Larix laricina Du Roi), paper birch (Betula papyrifera Marshall), and a willow cultivar (Salix miyabeana Seemen). In 2013, a 1-ha in situ experimental surface of mine tailings was set up on the gold mine site in Malartic, Abitibi-Témiscamingue, Quebec. The experimental site was subdivided into three blocks, each further divided in 5 plots. Each plot was randomly seeded as follows: 100% grass, 100% legumes, a mixture of both, topsoil, and a control (tailings only, no seeding). In the 2015 spring season, thirty seedlings of the three boreal tree species and cuttings of the willow cultivars were planted in each treatment plot. Seedling height and root biomass were measured at the end of the 2016 growing season. Soil sample analyses indicated significant differences for bulk density, wilting point, and organic matter content between the topsoil and the different agronomic herbaceous and control treatments; however, no significant differences were found between the different herbaceous treatments and the control for soil pH, bulk density, wilting point, macroporosity, and organic matter content. The mortality rate of jack pine, tamarack, and paper birch seedlings was higher in the control plots compared to all other treatments. Root biomass and height of the willow cultivar were significantly higher in the legumes compared with topsoil treatment. Among the four pioneer tree seedlings studied, this research indicates that the combination of the willow cultivar with the legumes treatment produces the best seedling growth and survival in the highly abiotic and stressful environments inherent to mine tailings.

This paper examines patterns in recently published research addressing Indigenous capacity for collaborative natural resource development in Canada’s forestry, energy, and mining sectors. As Indigenous involvement in natural resource development increases, so too does the body of associated scholarship. We gathered information on several core metrics (year of publication, authorship, and gender, author affiliation, journal titles, citation counts and impacts factors, and keywords) to analyze research output, trends, and gaps. Our bibliometric analysis of 49 articles from peer-reviewed journals confirms that Indigenous natural resource development and capacity research has steadily increased over the past decade in terms of the number and range of papers, authors, institutions, and cases examined. Research output peaked in 2013 and 2015. Authorship is distributed evenly between male and female lead researchers, with teams located across southern Canada, with highest concentrations in urban population centers of British Columbia, Manitoba, and Ontario. In contrast, the research sites are located in more northern, rural, and remote locations. That communities and projects under study are not currently matched with sites of research capacity raises questions about capacity building and the nature of research “on” versus “with” Indigenous peoples. Policies and programs designed to enhance Indigenous involvement and capacity must address these asymmetries in order to be representative, effective, and responsive to current Indigenous priorities.

This paper examines trends in enforcement of anti-cartel and antidumping laws in Canada since 1990. A major contribution is the creation of a timeline of Competition Bureau activity over the 1990–2019 period, possibly the first such effort. Simple regression analysis finds both types of enforcement measures to be counter-cyclical, consistent with previous work for other countries. They also seem to respond as expected to budgetary and exchange rate movements. Trends in these two measures are independent from each other, consistent with differing economic and political motivations behind the two, as well as differing actors responsible for instigating the two types of cases.

Residential reconversion can foster density and change the structure of neighborhoods. It also upsets current residents when it affects or obstructs their original panorama. Many nearby homeowners argue that new construction of visually imposing residential buildings negatively affects the value of their house. The aim of this paper is to test such a presumption by investigating whether single-family houses' prices are affected (or not) by being close to reconversions. The analysis is based on an exhaustive data set of residential reconversions that were recorded between 2006 and 2016 and is combined with a database of single-family transactions sold in Quebec City between 2004 and 2017. The results suggest that residential reconversions lead to a mean net price premium of about 2.48%. This effect, however, varies according to the type of residential reconversion as well as to the density of the reconversions. Results show no negative significant effects, which suggests that the reduction in house prices expected by residents, i.e., sellers, is largely compensated for by buyers' attraction, as expressed by market equilibrium.

This paper proposes a novel data preprocessing method that converts numeric data into representative graphs (polygons) expressing all of the relationships between data variables in a systematic way based on Hamiltonian cycles. The advantage of the proposed method is that it has an embedded feature extraction capability in which each generated polygon depicts a class-specific representation in the data, thereby supporting accurate "end-to-end learning" in industrial fault classification applications. Moreover, the generated polygons can play a significant role in the interpretation of trained deep learning fault classifiers. The performance of the proposed method was demonstrated using a benchmark dataset in the process industry. It was also tested successfully to classify challenging faults in major equipment in a thermomechanical pulp mill located in Canada. The results of the proposed method show better performance than other comparable fault classifiers. [ABSTRACT FROM AUTHOR]

Pectoral nerve blocks (Pecs I and Pecs II) are superficial thoracic wall blocks which block the pectoral and intercostal nerves. They can be used as analgesia/anesthesia for breast surgery and other procedures/surgeries involving the anterior chest wall (arteriovenous graft creation surgery, minimally invasive cardiac surgery and thoracotomy, etc.). The aim of this study is to evaluate publications in the scientific field of pectoral nerve blocks. ISI Web of Knowledge-Science was used for the analysis. All scientific works published included in the Science Citation Index Expanded (SCI-E) from 1975 to January 27, 2019, were analyzed. A retrospective search was performed using key words "pectoral nerve block," "PECS I," "PECS II," "pecs block," "PECS block,""Pecs I," "Pecs II," "PECS 1," "PECS 2," and "modified pecs I block." We further analyzed these results by the "analyze" function of the software in terms of number of papers for each country, type of documentation, number of publications per year, and name of journals and authors. The number of citations to published works was also calculated by using the citation function of the same software. 72 papers were found related to pectoral nerve block. The biggest contribution was from India (24.28%), and followed by Japan (14.28%), USA (14.28%), Canada (7.14%), Egypt (7.14%), Italy (5.71%), and South Korea (5.71%). The total number of publications increased sharply in years from 2014 (n = 1) to 2018 (n = 28). We have detected that papers on the use of pecs block in breast cancer surgery, which is one of the most common surgical procedure in the world, are few in the literature. With this study, we hope to increase the awareness on this area. We believe that pecs block applications will become widespread with the increasing use of ultrasound in anesthesia and the increase in education in this field. [ABSTRACT FROM AUTHOR]

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.

The Archean Horne deposit in the Noranda District, Quebec, Canada, is one of the world's largest volcanic massive sulfide (VMS) deposits, which has high economic benefits. Compared to other deposits in the Noranda region, Horne deposit has higher grades and huge storage of Au and Cu. Previous researches mostly focused on two-dimensional characteristics and statistical data, which cannot directly reflect the spatial structures and features of the Horne orebody. Therefore, in this paper, we used the GIS software to digitize the outline curves of massive sulfide and Cu grade values from paralleled level-plans and stope maps. Meanwhile, the spatial database of grade property was established. Based on the above results, the three-dimensional (3D) geological model and grade property model of the Horne orebody were established by software of Geological Object Computer-Aided Design (Gocad). According to the established 3D model of this paper, the spatial structure of the Horne orebody was analyzed and the existence of the ancient main faults cutting the Upper and Lower Horne orebodies was further speculated. Due to the function of main fault and spatial distribution of Cu grade in the 3D Cu property model, the position of hydrothermal vents of the Upper and Lower Horne orebodies and the direction of hydrothermal alteration inside the orebody were inferred. This paper summarizes the Cu enrichment process of the Horne deposit based on the 3D Cu property model and determination of the alteration zones. Furthermore, with the help of metallogenic geological background of the Horne deposit, it further explains that the hydrothermal mineralization model of Horne deposit is sericite-chlorite alternate alteration.

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]

Modular construction has become exceedingly relevant against the current scenario of increasing housing demand and can respond to this need in Canada due to its advantages of rapid construction. However, a holistic environmental sustainability framework for this construction method is still lacking. This paper proposes a hierarchical-based framework to benchmark the environmental performance of modular buildings versus conventional buildings. The framework identifies criteria and indicators affecting environmental sustainability, makes composite indicators, and establishes performance benchmarks. Based on expert survey, six criteria (construction waste management, energy performance and efficiency strategies, site disruption and appropriate strategies, renewable and environmentally preferable products, regional materials, and renewable energy use) are first identified. The related indicators and sub-indicators are combined to develop indices using Technique for Order of Preference by Similarity to Ideal Solution. Robust benchmark scales were established through application of Monte Carlo analysis on data collected through experts. Finally, the developed indices were compared against the benchmark scales at different assessment levels. The proposed framework was examined for two single-family modular buildings in British Columbia, Canada. The overall environmental performance benchmarking informs the policy makers on the usefulness of modular buildings, while the criteria-level indices direct the construction industry practitioners to improve the low performing indicators. The proposed framework will enhance the sustainability of modular and offsite construction in Canada. [ABSTRACT FROM AUTHOR]

Syrian refugee women face many obstacles when accessing health services in host countries that are influenced by various cultural, structural, and practical factors. This paper is based on critical ethnographic research undertaken in Canada, to explore Syrian refugee women migration experiences. Also, we aim at critically examining how the intersection of gender, trauma, and violence, and the political and economic conditions of Syrian refugee women shapes their everyday lives and health. The study also investigates the strategies and practices by which Syrian refugee women are currently addressing their healthcare needs and the models of care that are suggested for meeting their physical and mental health needs. Findings show that these women experienced constant worries, hardship, vulnerability, and intrusion of dignity. These experiences and challenges were aggravated by the structure of the Canadian social and healthcare system. This study offers a better understanding of the impact of migration and trauma on Syrian refugee women's roles, responsibilities, gender dynamics, and interaction with Ontario's healthcare system to improve interaction and outcomes. Healthcare models should address these challenges among Syrian refugee families in Canada. [ABSTRACT FROM AUTHOR]
