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 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.

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]

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]

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]

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 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]

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]

For many natural resource projects, the impact on Indigenous communities is a primary concern. Therefore, governance arrangements that account for the interests of companies, communities, and government are critical for the project's success. This paper looked at two successful mining projects in northern Canada, McArthur River and Diavik, to examine the governance arrangement that led to mutually beneficial outcomes. Through an analysis of interviews and documents, we assessed both governing institutions and interactions to understand how the respective companies and communities established a high level of trust. In both cases, government took a less prominent role in the management of resources, allowing the Indigenous communities to hold a stronger role in the governance of the resources. Both Indigenous communities, therefore, built partnerships with the company around socio-economic benefits along with environmental monitoring – redefining 'community' in governance arrangements.

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.

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.

The article reports that a research team in Canada is investigating an anaerobic microorganisms which can degrade oil hydrocarbons through fermentation. The study, which was funded by the oil industry and headed by Steve Larter of the University of Calgary, was able to produce methane as a byproduct. Methane was formed through the reaction with hydrocarbons in the oil to produce acetic acid, hydrogen and carbon dioxide. A combination of microbial studies, laboratory oil degradation experiments and case studies from various oilfields were used by the researchers. It was claimed that methane offers the same amount of energy as oil and gives off less carbon dioxide.

This Special Section explores the interplay between Indigenous peoples, industry, and the state in five proposed and active mining projects in Canada and Sweden. The overall aim is to identify factors shaping the quality of Indigenous community-industry-state interactions in mining and mine development. An ambition underlying the research is to develop knowledge to help manage mining related land-use conflicts in Sweden by drawing on Canadian comparisons and experience. This paper synthesizes the comparative research that has been conducted across jurisdictions in three Canadian provinces and Sweden. It focuses on the interplay between the properties of the governance system, the quality of interaction and governance outcomes. We combine institutional and interactive governance theory and use the concept of governability to assess how and why specific outcomes, such as mutually beneficial interaction, collaboration, or opposition, occurred. The analysis suggests there are measures that can be taken by the Swedish Government to improve the governability of mining related issues, by developing alternative, and more effective, avenues to recognize, and protect, Sámi rights and culture, to broaden the scope and increase the legitimacy and transparency of the EIAs, to raise the quality of interaction and consultation, and to develop tools to actively stimulate and support collaboration and partnerships on equal terms. Generally, we argue that Indigenous community responses to mining must be understood within a larger framework of Indigenous self-determination, in particular the communities' own assessments of their opportunities to achieve their long-term objectives using alternative governing modes and types of interactions.

Landslides involving sensitive clays are recurrent events in the world's northern regions and are especially notorious in eastern Canada. The two critical factors that separate sensitive clay landslides from traditional slope stability analysis are the highly brittle behavior in undrained conditions (strain-softening) characteristic of progressive or retrogressive failures and the large deformations associated with them. Conventional limit equilibrium analysis has numerous shortcomings in incorporating these characteristics when assessing landslides in sensitive clays. This paper presents an extensive literature review of the failure mechanics characteristics of landslides in sensitive clays and the existing constitutive models and numerical tools to analyze such slopes' stability and post-failure behavior. The advantages and shortcomings of the different techniques to incorporate strain-softening and large deformation in the numerical modeling of sensitive clay landslides are assessed. The literature review depicts that elastoviscoplastic soil models with non-linear strain-softening laws and rate effects represent the material behavior of sensitive clays. Though several numerical models have been proposed to analyze post-failure runouts, the amount of work performed in line with sensitive clay landslides is very scarce. That creates an urgent need to apply and further develop advanced numerical tools for better understanding and predicting these catastrophic events. [ABSTRACT FROM AUTHOR]

Volatile organic compounds (VOCs) in urban areas are of great interest due to their significant role in forming ground-level ozone and adverse public health effects. Emission inventories usually compile the outdoor VOCs emission sources (e.g., traffic and industrial emissions). However, considering emissions from volatile chemical products (e.g., solvents, printing ink, personal care products) is challenging because of scattered data and the lack of an effective method to estimate the VOCs emission rate from these chemical products. This paper aims to systematically analyse potential sources of VOCs emission in Canada's built environment, including volatile chemical products. Also, spatial variation of VOCs level in the ambient atmosphere is examined to understand the VOC relationship with ozone and secondary organic aerosol formation. The study shows that VOCs level may vary among everyday microenvironments (e.g., residential areas, offices, and retail stores) depending on the frequency of product consumption, building age, ventilation condition, and background ambient concentration in the atmosphere. However, it is very difficult to establish VOC speciation and apportionment to different volatile chemical products that contribute most significantly to exposure and target subpopulations with elevated levels. Thus, tracer compounds can be used to identify inventory sources at the consumer end. A critical overview highlights the limitations of existing VOC estimation methods and possible approaches to control VOC emissions. The findings provide crucial information to establish an emission inventory framework for volatile chemical products at a national scale and enable policymakers to limit VOCs emission from various volatile chemical products.

Community-based monitoring (CBM) is a widely used form of scientific data collection in which local community members directly participate in ecosystem research and also help the process by sharing traditional ecological knowledge and local understanding of land and resources. This paper presents a review of the challenges and opportunities associated with CBM projects in Canada and internationally. While Canadian cases are the primary focus, international examples are drawn on to provide additional context. Based on our review of 121 documents and publications, we found that CBM helps fill science research gaps by providing access to continuous data sets on the ecosystems being studied. CBM also increases the credibility of the data among users, as the community itself takes part in the environmental monitoring process. CBM supports cross-cultural learning and the co-production of knowledge by using traditional ecological knowledge with science, thereby enabling researchers, scientists and community members to learn from one another. Our review suggests that although there are multiple successes, CBM faces several challenges that constrain its progress including funding shortages, lack of support for local stewardship, and inadequate training for local users in the operation of equipment and data collection methods. Data sharing and rights on the use of data are also constraining to the long-term success of CBM programs. [ABSTRACT FROM AUTHOR]

This paper studies whether acculturation by immigrants and other minority groups is associated with economic integration in Canada. We examine immigrants' participation in winter sports, particularly hockey, as a proxy for acculturation given that these sports are popular in Canada but are rarely watched or practiced in the origin countries of many immigrants to Canada. Using the Canadian Community Health Survey, we find that practicing winter sports has a positive effect on the earnings of immigrants and other minority groups. Specifically, practicing winter sports closes the income gap between immigrants and natives. However, the gap does not decrease for visible-minority immigrants, suggesting that acculturation might not be sufficient to combat racial biases. [ABSTRACT FROM AUTHOR]

The automatic classification of marine species based on images is a challenging task for which multiple solutions have been increasingly provided in the past two decades. Oceans are complex ecosystems, difficult to access, and often the images obtained are of low quality. In such cases, animal classification becomes tedious. Therefore, it is often necessary to apply enhancement or pre-processing techniques to the images, before applying classification algorithms. In this work, we propose an image enhancement and classification pipeline that allows automated processing of images from benthic moving platforms. Deep-sea (870 m depth) fauna was targeted in footage taken by the crawler "Wally" (an Internet Operated Vehicle), within the Ocean Network Canada (ONC) area of Barkley Canyon (Vancouver, BC; Canada). The image enhancement process consists mainly of a convolutional residual network, capable of generating enhanced images from a set of raw images. The images generated by the trained convolutional residual network obtained high values in metrics for underwater imagery assessment such as UIQM (~ 2.585) and UCIQE (2.406). The highest SSIM and PSNR values were also obtained when compared to the original dataset. The entire process has shown good classification results on an independent test data set, with an accuracy value of 66.44% and an Area Under the ROC Curve (AUROC) value of 82.91%, which were subsequently improved to 79.44% and 88.64% for accuracy and AUROC respectively. These results obtained with the enhanced images are quite promising and superior to those obtained with the non-enhanced datasets, paving the strategy for the on-board real-time processing of crawler imaging, and outperforming those published in previous papers.

In 2011, an interdisciplinary symposium was organized in Toronto, Canada to investigate prevailing models of health policy change in the knowledge translation literature and to assess the applicability of these models for equity-focused urban health research. The papers resulting from the symposium have been published together, in the Journal of Urban Health, along with this introductory essay. This essay describes how the different papers grapple in different ways with how to understand and to bridge the gaps between urban health research and action. The breadth of perspectives reflected in the papers (e.g., social epidemiology, public health, political science, sociology, critical labor studies, and educational psychology) shed much light on core tensions in the relationship between KT and health equity. The first tension is whether the content of evidence or the context of decision making is the strong determinate of research impact in relation to health equity policy. The second tension is whether relationships between health equity researchers and decision makers are best viewed in terms of collaboration or of conflict. The third concerns the role that power plays in evidence-based policy making, when the issues at stake are not only empirical but also normative. [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]

The complexity of industrial processes imposes a lot of challenges in building accurate and representative causal models for abnormal events diagnosis, control and maintenance of equipment and process units. This paper presents an innovative data-driven causality modeling approach using interpretable machine learning and process mining techniques, in addition to human expertise, to efficiently and automatically capture the complex dynamics of industrial systems. The approach tackles a significant challenge in the causality analysis community, which is the discovery of high-level causal models from low-level continuous observations. It is based on the exploitation of event data logs by analyzing the dependency relationships between events to generate accurate multi-level models that can take the form of various state-event diagrams. Highly accurate and trustworthy patterns are extracted from the original data using interpretable machine learning integrated with a model enhancement technique to construct event data logs. Afterward, the causal model is generated from the event log using the inductive miner technique, which is one of the most powerful process mining techniques. The causal model generated is a Petri net model, which is used to infer causality between important events as well as a visualization tool for real-time tracking of the system's dynamics. The proposed causality modeling approach has been successfully tested based on a real industrial dataset acquired from complex equipment in a Kraft pulp mill located in eastern Canada. The generated causality model was validated by ensuring high model fitness scores, in addition to the process expert's validation of the results. [ABSTRACT FROM AUTHOR]

Aquatic monitoring programs are imperative for the functioning of the environmental impact assessment (EIA) process and a cornerstone for industrial compliance in Canada. However, in 2012, several leading pieces of federal environmental legislation (e.g., Canadian Environmental Assessment Act c.19, s. 52, 2012) were drastically altered, effectively weakening levels of environmental protection for aquatic ecosystems during project developments. This paper assesses the impact of CEAA 2012 on aquatic monitoring programs (and subsequent monitoring data reporting) across Canada for ten projects (five completed pre- CEAA 2012 and five completed post- CEAA 2012). Projects included four energy and six mining projects and were selected based on the following criteria: (i) representative of Canada's resource economy; (ii) project information was publicly available; and (iii) strong public interest. Projects pre - and post- CEAA 2012 exhibited few apparent differences before and after environmental regulatory changes. However, wide discrepancies exist in numbers and types of parameters reported, along with a lack of consistency in reporting. Projects pre- CEAA 2012 provided more follow-up monitoring commitments. Although qualitative differences remain inconclusive, this paper highlights requirements for further assessment of aquatic monitoring and follow-up programs in Canada. Recommendations for the government to consider during reviews of the federal environmental assessment processes include (i) improved transparency on the Canadian Environmental Assessment Agency website (); (ii) creation of a legally binding standardized aquatic monitoring program framework to ensure that all Canadian aquatic ecosystems are monitored with equal rigour; and (iii) commitments and justification related to frequency of aquatic monitoring of water quality.

Background: Adverse drug events (ADEs), harmful unintended consequences of medication use, are a leading cause of hospital admissions, yet are rarely documented in a structured format between care providers. We describe pilot-testing structured ADE documentation fields prior to integration into an electronic medical record (EMR). Methods: We completed a qualitative study at two Canadian hospitals. Using data derived from a systematic review of the literature, we developed screen mock-ups for an ADE reporting platform, iteratively revised in participatory workshops with diverse end-user groups. We designed a paper-based form reflecting the data elements contained in the mock-ups. We distributed them to a convenience sample of clinical pharmacists, and completed ethnographic workplace observations while the forms were used. We reviewed completed forms, collected feedback from pharmacists using semi-structured interviews, and coded the data in NVivo for themes related to the ADE form. Results: We completed 25 h of clinical observations, and 24 ADEs were documented. Pharmacists perceived the form as simple and clear, with sufficient detail to capture ADEs. They identified fields for omission, and others requiring more detail. Pharmacists encountered barriers to documenting ADEs including uncertainty about what constituted a reportable ADE, inability to complete patient follow-up, the need for inter-professional communication to rule out alternative diagnoses, and concern about creating a permanent record. Conclusion: Paper-based pilot-testing allowed planning for important modifications in an ADE documentation form prior to implementation in an EMR. While paper-based piloting is rarely reported prior to EMR implementations, it can inform design and enhance functionality. Piloting with other groups of care providers and in different healthcare settings will likely lead to further revisions prior to broader implementations. [ABSTRACT FROM AUTHOR]

In theory, the nearest-nickel rounding scheme renders no financial gains for anyone given that each final digit has the same probability of appearing. However, in practice, rounding may yield non-zero net effects as most store prices end with nine. In this paper, price data from representative Canadian grocery stores are used to assess whether the current rounding system imposes a monetary loss on firms or consumers. Specifically, I evaluate how one- to ten-item purchases and the six different Canadian provincial sales tax rates influence penny-rounding. The results show that penny-rounding financially benefits the firms at the expense of the consumers, imposing a net transfer of approximately $3.27 million CAD from consumers to grocery vendors every year. This amount averages to $157 of additional revenue for a typical grocery store per year. [ABSTRACT FROM AUTHOR]

The second quantum revolution has been producing groundbreaking scientific and technological outputs since the early 2000s; however, the scientific literature on the impact of this revolution on the industry, specifically on start-ups, is limited. In this paper, we present a landscaping study with a gathered dataset of 441 companies from 42 countries that we identify as quantum start-ups, meaning that they mainly focus on quantum technologies (QT) as their primary priority business. We answer the following questions: (1) What are the temporal and geographical distributions of the quantum start-ups? (2) How can we categorize them, and how are these categories populated? (3) Are there any patterns that we can derive from empirical data on trends? We found that more than 92% of these companies have been founded within the last 10 years, and more than 50% of them are located in the US, the UK, and Canada. We categorized the QT start-ups into six fields: (i) complementary technologies, (ii) quantum computing (hardware), (iii) quantum computing (software/application/simulation), (iv) quantum cryptography/communication, (v) quantum sensing and metrology, and (vi) supporting companies, and analyzed the population of each field both for countries, and temporally. Finally, we argue that low levels of quantum start-up activity in a country might be an indicator of a national initiative to be adopted afterwards, which later sees both an increase in the number of start-ups, and a diversification of activity in different QT fields.

The aim of this paper is to map the emergence and development of a research field around the topic of "gender-based violence (GBV) against women with precarious legal status and their access to social protection in advanced welfare societies". We explore the academic knowledge production around this topic as a specific research field by using bibliometric data. We investigate the place occupied by scholars who publish in well-established journals, and their disciplines, in order to understand the relevance of different disciplines and groups of researchers in the knowledge production within the field. Our methodology includes analysis of co-authorship, cross-country collaboration, and co-citation. The search strategy is informed by discursive practices and knowledge production by influential international civil society actors (CSAs) involved in framing welfare responses to GBV against women with precarious legal status. Our results suggest that the knowledge produced in the field increased in terms of number of publications between 2010 and 2021, indicating a process of institutionalisation. Disciplines oriented towards certain groups of professionals such as clinical psychology, medicine, health, nursing, and social work, affiliated mainly to institutions in the US, Canada, and the EU, have a prominent role in knowledge production in this field. In our conclusions, we discuss the implications of these results in relation to gender studies and migration studies, along with some limitations of the use of bibliometrics software combined with an intersectionality approach.

Background: Point-of-care ultrasound (POCUS) is a growing part of internal medicine training programs. Dedicated POCUS rotations are emerging as a particularly effective tool in POCUS training, allowing for longitudinal learning and emphasizing both psychomotor skills and the nuances of clinical integration. In this descriptive paper, we set out to review the state of POCUS rotations in Canadian Internal Medicine training programs. Results: We identify five programs currently offering a POCUS rotation. These rotations are offered over two to thirteen blocks each year, run over one to four weeks and support one to four learners. Across all programs, these rotations are set up as a consultative service that offers POCUS consultation to general internal medicine inpatients, with some extension of scope to the hospitalist service or surgical subspecialties. The funding model for the preceptors of these rotations is predominantly fee-for-service using consultation codes, in addition to concomitant clinical work to supplement income. All but one program has access to hospital-based archiving of POCUS exams. Preceptors dedicate ten to fifty hours to the rotation each week and ensure that all trainee exams are reviewed and documented in the patient's medical records in the form of a consultation note. Two of the five programs also support a POCUS fellowship. Only two out of five programs have established learner policies. All programs rely on In-Training Evaluation Reports to provide trainee feedback on their performance during the rotation. Conclusions: We describe the different elements of the POCUS rotations currently offered in Canadian Internal Medicine training programs. We share some lessons learned around the elements necessary for a sustainable rotation that meets high educational standards. We also identify areas for future growth, which include the expansion of learner policies, as well as the evolution of trainee assessment in the era of competency-based medical education. Our results will help educators that are endeavoring setting up POCUS rotations achieve success. [ABSTRACT FROM AUTHOR]

In many countries, loan guarantee programs are important elements of government policy with respect to small- and medium-sized enterprises (SMEs). If loan guarantee schemes are to be effective, a majority of firms obtaining assistance through such a scheme ought not to be able to obtain financing from existing sources: a property known as incrementality or additionality. This paper describes a new approach to measuring incrementality. This work uses a two-stage process to estimate the incrementality of loans made under the terms of the Canada Small Business Financing (CSBF) program. First, a logistic regression-based model of loan outcomes (essentially a credit-scoring model) is estimated based on a large representative sample of SMEs. The resulting model was consistent with prior expectations and exhibited high levels of goodness-of-fit. The model was then employed to classify a sample of firms that had received loans under the terms of the loan guarantee scheme. Incremental loans ought to be classified as “turndowns” by the model; hence the proportion of loan guarantee recipients that the model classified as turndowns is a direct measure of incrementality.

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).

Using five cycles of a large nationally representative Canadian health survey, covering 2008 to 2012, the present paper examines the extent of labour earnings and household income gaps among gays, lesbians, and heterosexuals. The data used in this paper has the advantage of allowing for a direct classification of sexual orientation, through respondent self-identification. In accord with previous reports, this paper finds that homosexual females holding fulltime employment earn statistically significantly above comparable heterosexual females. Homosexual males with fulltime employment, on the other hand, are found no different in their earnings, from otherwise identical heterosexual males. When household income is considered, data reveal that lesbian households have statistically significantly lower incomes compared with otherwise identical gay households, who outearn heterosexuals as well. This pattern, not previously reported for Canada but observed in some other countries, is likely due to the combined effects of the general gender wage gap, the fading of homosexual males’ wage penalty, and the existence of two male income earners in a gay male household.

Minority entrepreneurs significantly contribute to Canada's economic development. This contribution to the Canadian economy comes in various forms, including setting up businesses such as convenience stores, ethnic restaurants, and financial services. This paper aims to explore the motivation for entrepreneurship among Black population in Alberta, Canada. Using in-depth interviews and focus group discussions, the study shows that many Black entrepreneurs are "pulled" rather than "pushed" into entrepreneurship. Although some participants were pushed into entrepreneurship because of labor market exclusion, the majority were opportunity seekers who pursued entrepreneurship as a strategic response to opportunity structures in their environment rather than a reactive response to escape ethnic penalties. This study emphasizes the complex relationships between minorities' characteristics and resources and the opportunity structures that affect the ability to start a business. [ABSTRACT FROM AUTHOR]

The role of corporations in societal outcomes continues to grow. Mining companies now face the expectation of not only providing economic benefits to communities, but act as a facilitator for social wellbeing and environmental stewardship. In the mining sector, this has placed renewed attention to defining corporate social responsibility and, in turn, how social license to operate is understood. These developments are particularly pertinent when mining operations affect Indigenous communities – where land use is central to livelihood. This study looks at the community engagement strategies of two mining companies in northern countries, Cameco (Canada) and Boliden (Sweden). By comparing their approaches, this paper explores the development of their practices over time and assess to what extent their corporate policy has translated into everyday practice and outcomes. The findings of demonstrate that high levels of trust are established when corporate approaches are built around transparency and collaboration – resulting in agreements that include long-term partnerships around socio-economic and environmental management.

Canada has made a commitment in the Paris Agreement to reduce its total greenhouse gas emissions by 40–45% from 2005 levels by year 2030 and achieving net-zero emissions by year 2050. An enhanced target has been established for the electricity sector, aiming to achieve a reduction of 88% from 2005 levels by 2030. Achieving these ambitious targets requires the implementation of new CO2 reduction measures and policies. In this work, carbon emissions pinch analysis (CEPA) is used for planning energy resources in the electricity sector while aiming to achieve both country and regional targets. Different scenarios are proposed for years 2030 and 2050 based on current policies and extension of some realistic assumptions, including the use of carbon capture and storage (CCS) facilities, negative emissions technologies (NETs), and increased capacity for renewable energy sources. In year 2030, the proposed solution indicates that the reduction of CO2 emissions of 3.1 Mt CO2-eq. is achievable, which is lower than the country target of 14 Mt CO2-eq. This solution can serve as the benchmark for each stakeholders at provincial level to reach their regional target. Results also show that electricity and CO2 trading are required to meet the energy requirement and to achieve the year 2030 CO2 emissions reduction goal at the provincial level which is the novelty of this paper. Although none of the cases has met net-zero emissions in year 2050, they do demonstrate that net zero is not far from materialisation. [ABSTRACT FROM AUTHOR]

This paper describes the dataset of measurements collected and published in the context of the comprehensive experimental campaign on downburst-like outflows that was performed at the WindEEE Dome at Western University, Canada. Downbursts are strong downdrafts of air that originate from thunderstorm clouds and create vigorous radial outflows upon hitting the ground. Downbursts are here simulated as transient phenomena produced by large-scale impinging jet. Two jet velocities were adopted in the experiments. The three-component velocity measurements were recorded using 7 Cobra probes mounted on a vertical stiff mast and displaced at 10 radial positions in respect to the downdraft centerline. For every radial position, each experiment with the same initial condition was repeated 20 times to inspect the deterministic features of the signal. Overall, the total of 2800 tests (2 jet velocities × 20 repetitions × 10 radial positions × 7 heights) represent one of the largest experimental campaigns on downburst winds carried out in a wind tunnel facility thus far.

This concept paper builds on comparative work on sustainable agriculture in Canada and Cuba by exploring the role of agricultural co-operatives. Findings indicate that Canada and Cuba's agricultural co-operatives face the challenges of membership renewal and economic presence in their national economies. The paper argues that components of each agricultural co-operative system at the farm and tertiary levels could be adapted to the other nation's agricultural co-operatives in order to strengthen community control of local food systems. The paper further argues that a new approach to agricultural co-operatives must incorporate the state itself in any potential reform agenda in both countries. The paper calls for movement-to-movement contacts between the two countries, and the wider Americas. [ABSTRACT FROM AUTHOR]

This paper is concerned with how government research funding and collaboration between researchers affect academic technological production in the context of nanotechnology in Canada and in the United States. We use the co-invention and co-authorship networks of scientists to build indicators of collaborative behaviour and investigate whether the nature of the network plays a role in the academic technological productivity and quality. Results suggest that technological output has the potential to offer governments useful guidance concerning the effectiveness of academic grants and collaboration in the United States and in Canada. This paper provides evidence that the position of researchers in both co-invention and co-publication networks does influence technological productivity and quality. [ABSTRACT FROM AUTHOR]

In cities across Canada, suburbs have become important immigrant-receiving sites. This 'suburbanization of immigrants' is significantly affecting the housing situation in the Vancouver area, as the market responds to the preferences and requirements of new immigrant groups. This paper draws from a case study examining the settlement and housing experiences of recent immigrants from Mexico living in three Vancouver suburbs (Burnaby, Surrey, and Abbotsford). The findings from our survey of 129 Mexican immigrants and interviews with 60 key stakeholders reveal that housing affordability is a major issue for Mexican immigrant homeowners and renters. Almost half of the survey respondents spent more than 30% of their monthly income on housing. Renters used various strategies to afford housing, including sharing housing with relatives and co-ethnic friends (sometimes in overcrowded conditions), while some homeowners sublet rooms or rented out basement suites. The findings also revealed that in addition to facing employment and housing market challenges similar to other immigrant groups in Vancouver, Mexican immigrants experienced housing discrimination related to suspicions about undocumented immigration. Despite facing barriers to integration, the Mexican immigrants in our study were largely successful in improving their housing status in Canada. Policymakers and service planners must understand the 'ethnic refashioning' of major city suburbs and the housing issues faced by new groups of immigrants to better assist their integration.

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.

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.

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.

Climate change impacts on Indigenous peoples in remote regions pose unique institutional challenges and opportunities for governments. Reducing vulnerability and enabling collaborative knowledge creation through the inclusive consideration of Indigenous peoples' perspectives in government and institutional efforts can help to advance adaptation to environmental change. In Northern Canada, Indigenous communities and multiple levels of the Canadian government and its institutions, including the Canadian Armed Forces, share the commensurate task and responsibility of responding to, tracking, monitoring and adapting to rapid climatic changes and impacts associated with climate change in the Arctic. In this review paper, we explore how Canadian governments may effectively work as partners and catalysts for advancing mutually beneficial climate change adaptation efforts with Indigenous peoples and communities affected by climate change in remote Arctic regions of Northern Canada. We review knowledge and concepts related to Indigenous traditional ecological knowledge in the context of institutional adaptation planning and policy approaches in remote regions. First, we provide a geographical and contextual background that informs the efforts of institutional partners and Indigenous communities seeking to mutually address long-term challenges associated with adapting to climate change, specifically in the remote Canadian Arctic. Second, we unpack knowledge for advancing collaborative adaptation efforts between Indigenous peoples and institutions in the Arctic. We identify relevant gaps and opportunities for enhancing institutional approaches to climate change adaptation involving Indigenous peoples in remote regions like the Arctic. We conclude with a summary of policy relevant insights for future research. [ABSTRACT FROM AUTHOR]
