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]

Existing estimates of methane fluxes from North American wetlands vary widely in both magnitude and distribution. In light of these disagreements, this study uses atmospheric methane observations from the US and Canada to analyze seven different bottom-up, wetland methane estimates reported in a recent model comparison project. We first use synthetic data to explore how well atmospheric observations can constrain wetland fluxes. We find that observation sites can identify an atmospheric pattern from Canadian wetlands but not reliably from US wetlands. The network can also identify the spatial distribution of fluxes in Canada at multi-province spatial scales. Based upon these results, we then use real data to evaluate the magnitude, temporal distribution, and spatial distribution of each model estimate. Most models overestimate the magnitude of fluxes across Canada. Most predict a seasonality that is too narrow, potentially indicating an over-sensitivity to air or soil temperatures. In addition, the LPJ-Bern model has a spatial distribution that is most consistent with atmospheric observations. Unlike most models, LPJ-Bern utilizes land cover maps, not just remote sensing inundation data, to estimate wetland coverage. A flux model with a constant spatial distribution outperforms most other existing flux estimates across Canada. [ABSTRACT FROM AUTHOR]

Postsecondary students, staff, and faculty across North America are actively involved in transforming food systems on campuses and beyond. Much of the scholarship documenting these inroads has focused on procurement, production, and pedagogy. While this work is essential, it paints an incomplete picture of the ways postsecondary campuses—and students in particular—are contributing to realizing more just and sustainable food systems. In this paper, we elaborate the contours of what we propose as the alternative campus foodscape in Canada by highlighting campus food systems alternatives (CFSAs), which we define as on-campus initiatives that are motivated by animating structural, practice, and/or policy change through the campus foodscape. We demonstrate how CFSAs are distinct from conventional food systems and argue that they are essential elements of a robust movement for food systems transformation. [ABSTRACT FROM AUTHOR]

Jean Raspail's controversial 1973 novel The camp of the saints predicts mass migration to Europe that will destroy European civilization. Decades later, the book has accurately predicted the hundreds of thousands of refugees arriving in Europe annually, prompting a continent-wide crisis. From Lesbos and Lampedusa to the Canary Islands and Calais, no one seems to know how to stem the flow of humanity. Borders are being resurrected, despite Schengen and European Union (EU) agreements, in an effort to control the movement of populations. European governments disagree on how to proceed and some are suggesting that the EU could be torn apart by differing approaches to the problem. But does this have to be the response to the migration crisis? This paper compares the predictions of The camp of the saints to events in Europe today and critiques the book's conclusions with regard to what is an ancient phenomenon: movements of migrants from surplus to deficit labor settings. The paper will also evaluate the response to migrants in the United States under its populist president, Donald Trump, and will review related issues in other parts of the world: Turkey, Russia, and Canada. Contrary to Raspail's predictions, world leaders will need to accept what has already become a de facto reality: large scale admission of migrants and refugees to the EU and North America, as full citizens, will be the only realistic way to preserve prosperity in the years to come.

Climate change has facilitated the introduction, establishment, and movement of invasive species in northern regions, enabling the colonization of previously unsuitable areas. While the responses of insects to these changes have been increasingly studied, our understanding of how such alterations impact trophic interactions still requires further research to make reliable predictions about the spread of diseases in a warming world. Phytoplasmas, a group of obligate parasitic unculturable Mollicutes, primarily rely on leafhoppers (Hemiptera: Cicadellidae) for transmission, spread, and survival. Phytoplasmas are associated with over 600 diseases affecting more than 1,000 plant species, including berries, grapevines, and other small fruits. In North America, diseases such as grapevine yellows, blueberry stunt, and strawberry green petal diseases have been linked to phytoplasma strains transmitted by known leafhopper species. However, the number of phytoplasma diseases has significantly increased in North America over the past decade, suggesting the presence of unidentified vectors or an abundance of leafhopper vectors. This short review provides an overview of the current knowledge on leafhoppers as vectors of phytoplasmas to berries, focusing on the last decade's research in Canada. This paper also explores the potential implications of climate change on this pathosystem, including the anticipated range expansion of leafhopper species, changes in phytoplasma acquisition and transmission, and the risk of new leafhopper-transmitted plant-pathogen introductions through the arrival of new leafhopper species.

Similar to many freshwater ecosystems, the Laurentian Great Lakes of North America have undergone numerous anthropogenic stressors resulting in considerable loss of biodiversity and habitat. Among Great Lakes fishes, the coregonine sub-family has endured the most extensive declines, including extinction of several species (Coregonus johannae, C. alpenae, and C. kiyi orientalis) and at least 10 instances of local extirpations of other species (C. nigripinnis, C. reighardi, C. zenithicus, C. hoyi, and C. artedi) across all 5 lakes, much of which occurred prior to the 1960s owing to overfishing, interactions with non-indigenous species, and habitat loss. Despite these declines, no federal-, provincial-, or state-mandated actions were ever implemented to conserve coregonine diversity, potentially because so much of the coregonine declines occurred prior to the enactment of federal conservation legislation. Possible explanations for inaction since enactment of that legislation include insufficient data on biological vulnerability or threats, unresolved taxonomy, and limited support from the fishery management agencies and their stakeholders prior to the 2000s. In recent decades, however, several fishery management agencies have undertaken efforts to re-introduce coregonine diversity. These efforts helped lead to development of a science-based framework to restore coregonines that was universally endorsed by fishery managers representing eight U.S. states, four U.S. tribal organizations, and the province of ON, Canada, in May 2018. The basin-wide framework is based on principles of conservation biology and adaptive management. We describe details of its key steps, including planning, restoring, and evaluating, while also describing recent implementation efforts to develop methods, improve available resources, and enhance coordination across the basin. Although our paper describes a regional effort to restore native coregonines, our adaptive-management approach could be used by other multi-agency stakeholders seeking to conserve or restore native fishes.

This paper compares surface signatures of the zonally symmetric and asymmetric modes of stratospheric variability, which describe the strength of the polar vortex and a planetary wave‐1 pattern, respectively. Unlike a weak polar vortex followed by negative Arctic Oscillation–like anomalies, strong stratospheric wave activity features a polar vortex displacement with a deep planetary wave‐1 structure, resulting in positive North Atlantic Oscillation–like North American cooling in about 10 days. Moreover, the linkage between the stratosphere and surface is examined in two reanalyzes and four models of different configurations, which show more robust North American cooling following the displacement of the polar vortex due to strong stratospheric wave activity than the zonally symmetric weakening of the polar vortex. This suggests strong stratospheric wave activity acts as a better predictor for cold spells in the northern U.S. and Canada compared with a weak polar vortex. Plain Language Summary: A weak polar vortex in the winter stratosphere is likely associated with cold spells at the surface, yet there are large uncertainties in predicting surface cold events based on stratospheric signals. This study introduces a new method to separate stratospheric variability into the leading modes of zonally symmetric and asymmetric circulations. The zonally symmetric mode describes the strength of the polar vortex. A weak polar vortex is followed by cooling over northern Eurasia and midlatitude North America. In contrast, the zonally asymmetric mode characterizes a displacement of the polar vortex or a planetary wave‐1 pattern, with the positive phase featuring a high anomaly over North America and a low anomaly over Eurasia. This stratospheric wave pattern extends down to the surface, resulting in North American cooling and Eurasian warming in about 10 days. While both stratospheric modes are associated with surface cooling over North America, the linkage is more robust for the displacement than the zonally symmetric weakening of the polar vortex, based on analyses of several reanalyzes and models. This indicates that strong stratospheric wave activity serves as a better predictor for cold air outbreaks in the northern U.S. and Canada than the commonly used weak polar vortex events. Key Points: Distinct North American cooling signatures follow zonally symmetric and asymmetric modes of the stratosphereStrong stratospheric wave activity precedes positive North Atlantic Oscillation like North American coolingThe linkage between the stratospheric wave activity and the surface is robust in reanalyzes and models [ABSTRACT FROM AUTHOR]

There is a growing interest in English-speaking jurisdictions, including Australia, North America, Canada, the United Kingdom and New Zealand, about the prevention of sexual abuse perpetrated by children against other children. The aim of this review was to identify opportunities for research, policy and practice which could enhance the prevention agenda relating to the perpetration of sexual abuse by children through conducting a Critical Interpretive Synthesis. Eleven electronic databases were searched in the period from 22 April to 23 May 2013 and included: SocINDEX, Social Services Abstracts, Applied Social Sciences Index and Abstracts, Family and Society Studies Worldwide, Project Muse, PsychINFO, Family and Society Plus, Jstor, Expanded Academic ASAP, Web of Science and Google Scholar. Key individual journals were also searched, including Child Abuse and Neglect and the Journal of Interpersonal Violence, as well as the grey literature. The search was guided by the research question: How could the prevention agenda relating to sexual abuse perpetrated by children be enhanced? The systematic literature search yielded 3323 titles, and 34 of these papers were included in the final synthesis. The authors identified five domains operating in the evidence base: characteristics, causes, communications, interventions and treatments. A synthesising construct emerged from the review: prevention-enhancing interactions. This construct referred to the potential for enhancing the prevention agenda which exists as the evidence domains interact with one another, and with the public health model of prevention. The authors consider this review to be a timely contribution to the current agenda pertaining to sexual abuse perpetrated by children. It provides researchers, policy makers and practitioners in the field with an evidence-informed conceptualisation of opportunities for enhancing prevention work. [ABSTRACT FROM AUTHOR]

Newly available information has made it possible for the first time to examine the role of intelligence in decisions on the CF-105 Arrow. These records show that Canadian intelligence assessments of the Soviet bomber threat differed from US estimates. In the late 1950s Canadian analysts stressed the imminent shift from bombers to ballistic missiles as the main danger to North America. The Diefenbaker government's decision to cancel the Arrow program in 1959 was significantly influenced by this view of the changing strategic threat. In examining the role of intelligence, the article addresses a number of earlier myths, and provides a more complete picture of the decisions concerning this iconic Canadian aircraft.

The composition of the lower continental crust, as well as its formation, growth, and evolution, remains a fundamental subject to be understood. In this study, we carry out a comparative and integrative analysis of seismic tomographic models, teleseismic receiver function results, and Airy isostasy in order to investigate the properties of the lower continental crust in eastern North America. We extract the depths for Vs of 4.0 km/s, 4.2 km/s, and 4.5 km/s from three selected tomographic models and calculate the differences between the Vs depth contours and the Moho depth defined by receiver functions. We then calculate the Airy isostatic Moho depth and its misfit with the receiver‐function‐defined Moho. Our analysis reveals three key features: (a) the deepening of the Vs depth contours and the strong negative Airy misfit within the U.S. Grenville Province; (b) a seismically faster‐than‐average and compositionally denser‐than‐average lowermost crust in the eastern North American Craton and the Grenville Province; and (c) the thickest, seismically fastest, and densest lowermost crust beneath the southern Grenville Front, the southern Grenville‐Appalachian boundary, and the U.S.‐Canada national border. We suggest that the lower crust of the craton and the Grenville Province has densified through garnet‐forming metamorphic reactions during and after orogenesis, contributing to the widely distributed fast‐velocity layer. The lower crust beneath the tectonic boundaries could have experienced more extensive garnet growth during orogenesis and emplacement of mafic magma. This study provides new constraints on the seismic and compositional properties of the lower crust in eastern North America. Plain Language Summary: The continental crust provides important clues about the formation and evolution of the Earth. However, the dominant composition of the lower part of the continental crust remains enigmatic, especially in the regions where the seismic velocities are significantly faster than the global average. In this paper, we investigate the properties of the lower continental crust in eastern North America by comparatively analyzing two types of data sets: (a) the variations of seismic velocity within the crust and (b) the variations of the crustal thickness. Our comparative and quantitative analysis reveals that the lower crust of the eastern North American Craton and the Grenville Province is seismically faster and compositionally denser than the global average. The thickest, seismically fastest, and compositionally densest lower crust is roughly along the orogenic fronts and the U.S.‐Canada national border. We suggest that garnet growth within the lower crust is a viable mechanism for forming the widely distributed fast‐velocity layer in eastern North America. The lower crust may have been further densified through extensive garnet growth and emplacement of mafic magma at a regional scale. Key Points: A high‐velocity lower continental crust distributes widely in eastern North AmericaThe seismically fastest and densest lower crust is roughly along the orogenic frontsThe lower crust densifies through the metamorphic growth of dense minerals [ABSTRACT FROM AUTHOR]

This paper examines the visual cultures of early civil rights activism in Canada in the period following the enactment of the country's first citizenship laws in 1947. It does so through a close study of the use of family photographs in The Clarion (1946–49), an African-Canadian–owned Atlantic newspaper which regularly reprinted family photographs on its front cover and within its pages, alongside reports on racial discrimination, calls for political activism and celebrations of the achievements of Black Canadians. Paying particular attention to The Clarion's reporting on the arrest of Viola Desmond – a local beautician who publicly challenged segregation laws in a Nova Scotia movie theatre in 1946 – the essay charts how these domestic and private images prefigured now well-established debates about respectability politics and quietness in civil rights discourse and image making on both sides of the border. It seeks not to resolve these tensions but to demonstrate the uneasy ways questions of self presentation have informed the imagery of citizen claims by racialised subjects in North America in the post-war period.

This paper examines the issue of integration versus segmentation of the Canadian equity market relative to a global North American market. We compare the international and domestic versions of the CAPM, and find that integration, or the mean-variance efficiency of the global market index, is rejected by the data. Segmentation is the preferred model, based on a maximum likelihood procedure correcting for thin trading. We further divide the sample into securities that are interlisted in Canada and the U.S., and those that are not. Integration is rejected for both groups, which indicates that the source of segmentation can be traced to legal barriers based on the nationality of issuing firms. [ABSTRACT FROM AUTHOR]

The article reproduces the four original papers which served as the thematic base for the media production of the 1970 National Convention of the American Alliance for Health, Physical Education and Recreation (AAHPER) in Seattle, Washington and at the Canadian Biennial AHPER Convention of 1971. These papers are "Is Sport the Struggle or the Triumph?," by W. R. Morford, "Are Sports Education?," L. F. Locke, "Is Sport Really Colorblind?," and "Is Sport Experience?," by Seymour Kleinman. The papers examine the relevance of sports in a changing society.

Environmental pollution is a growing concern for many organizations, commissions, state governments, and companies. The use of fossil fuels in transportation contributes significantly to increased emissions of harmful sulfur oxides (SOx) and nitrogen oxides (NOx). Maritime transport, as one of the largest emitters of such harmful compounds, has encountered many emission restrictions and legal limitations. These include the creation of areas of strict exhaust gas control (ECA). According to the MARPOL Convention, Annex VI, Special Emission Control Areas have been in force since 01.01.2015, and they include the following areas: the Baltic Sea, North Sea, North America (covering the designated coasts of the USA and Canada and portions of the Caribbean Sea near the USA). According to current regulations, vessels providing services in ECAs are required to maintain sulphur oxide emissions that do not exceed 0.1%. The introduction of new regulations results in costs that have to be covered by shipowners. To meet these standards, the two most popular methods are the use of special flushing systems (scrubbers) and low-sulphur fuels (e.g., LNG). This publication addresses the use of LNG as fuel for the main propulsion of sea-going vessels operating in areas covered by strict sulphur emission controls. It also presents LNG demand forecasts for various ship types, as well as possible solutions satisfying the Sulphur Directive. The purpose of this paper is to present a way to determine the size of the global demand for LNG. The percentage of vessels powered by LNG and other fuels was used as a basis for estimating global LNG demand in shipping until 2030. [ABSTRACT FROM AUTHOR]

Here, we present a historical review of important published studies of submerged prehistoric sites in North America prior to 1990. Prior to that point, a review of mid-twentieth century literature on the subdiscipline demonstrates that "prehistoric" was not a significant element in practice. In the U.S.A. and Canada, very few professional papers or articles were published on the topic of submerged prehistoric archaeological sites until mid-century or later. Most early studies were written by avocational archaeologists or specialists from other disciplines interested in archaeology. This changed in the 1970s, when formal surveys, reports, and publications written by academically trained archaeologists increasingly appeared in peer-reviewed journals and edited volumes. By the 1980s the establishment of underwater prehistoric archaeology as new sub-discipline was well underway. This review is designed to give the reader a brief overview of the discipline as it matured, though we lack the space to provide a full critical analysis here. [ABSTRACT FROM AUTHOR]

This paper troubles dominant understandings of North American feminist history as a series of successive, ideologically opposed, generational "waves." While several scholars have critiqued this metaphor, few have grounded their critiques in the lives, perspectives, and organizing strategies of women involved in feminist activism. This paper draws on research with older Canadian women activists involved in the Grandmothers Advocacy Network (GRAN) to call into question three existing critiques of the waves metaphor: its implicit ageism, its simplistic categorizations, and its assumed generational discord. In so doing, it illustrates how women's lives and mobilizations are far too intricate for this framework. This paper thus contributes to understanding the complexities of contemporary feminist activism, particularly as these complexities relate to the contributions of older activists.

As national borders tighten against undocumented migrants, agricultural employers throughout North America have pushed governments for easier access to a legalized temporary farm workforce. Some U.S. farmers and policymakers are seeking to expand the country's temporary agricultural guest worker program (H-2A visa), while Canada's longstanding Seasonal Agricultural Worker Program has been elevated as an international role model because it fulfills employer demands for a stable workforce, enables state control over migration flows and, at least on paper, safeguards workers' rights. However, researchers have documented systemic violations of workers' rights in both countries. In this paper we ask: How do the Canadian and U.S. agricultural guestworker programs measure up against international standards of best practices for the treatment of migrant workers? We draw on a food regime framework to historicize agricultural labourmigration policies in both countries within broader patterns of capital accumulation in the global agri-food system, and we argue that Canadian and U.S. agricultural guestworker programs offer evidence of the substantiation of a third food regime. Finally, we argue that despite differences in the policy environments and structures of these programs, their future expansion would further entrench systemic violations of international standards for the treatment of migrant workers by host country governments.

Purpose – The purpose of this paper is to provide a critical analysis of the history and development of public relations education in the USA and Canada. Design/methodology/approach – The research methodology used for this paper is the historical/critical analysis approach. Findings – This paper finds more differences than similarities between public relations educational development in the two countries. The first PR course at a US university was taught at the University of Illinois in 1920 and the first US degree program was offered by Boston University in 1947. The first Canadian university PR course was taught at McGill University n 1948 and the first university degree was offered by Mount Saint Vincent University in 1977. Although PR courses and degrees are offered at a small number of élite US universities, the greatest recent PR curriculum development has been at smaller, second- or third-tier institutions. While a few Canadian universities offer courses and degree programs in the field, most of Canada's recent PR program growth has been at colleges rather than at universities. Practical implications – Rightly or wrongly, academic institutions often look to North America for direction when it comes to establishing and developing public relations education programs. A number of factual inaccuracies about public relations education history have frequently surfaced in books and journal articles. This paper corrects a number of those inaccuracies and in doing so improves public relations scholarship. Originality/value – A thorough review of the literature suggests that this paper represents the only journal-length piece about the history and development of public relations education in Canada and the USA.

The effect of public capital on private sector productivity has received much attention in the literature. The impact of an adjacent country's public capital on domestic productivity has, however, not been previously examined. This paper attempts to fill this gap by examining the possibility of such spillovers from the USA to Canada. Due to close proximity of both countries, the hypothesis of the paper is that these spillovers are important. A production function model introduces US public capital as an exogenous variable and tests for its significance. The results indicate positive spillovers from the USA public capital to Canadian productivity. [ABSTRACT FROM AUTHOR]

The archaeology of hunters and gatherers has long focused on the economic and technological dimensions of food use and procurement. In marginal environments especially, hunter-gatherer food use has often been situated within an adaptationist calculus of survival and environmental accommodation. The ethnographic record of hunter-gatherers that inhabited such environments, however, indicate that social and cultural considerations also critically informed indigenous peoples' procurement, consumption, and discard practices. Drawing on the later prehistoric and early historic archaeological record of the island of Newfoundland, in northeastern Canada, this paper explores how the procurement, consumption, and handling of subarctic foods conveyed identity, reflected historical conditions and social relations, factored into ritual and ceremonial practice, and embodied worldviews.

The higher religiosity of women in the Western Christian societies is one of the best documented findings in the religious scholarship. In spite of the recent vibrancy of secular movements in North America, the higher religiosity of women appears persistent. As a result, the gender ratio is greatly skewed in the secular groups in favour of males. For instance, for every atheist female in North America, there are at least three males. Using the Canadian General Social Surveys of 1985–2014, this paper examines how the gender religiosity gap has evolved among the Canadian-born. Throughout the period, Canadian-born women are found less likely to be unaffiliated and show a greater frequency of religious attendance. The religious attendance gap is found to be closing. The unaffiliation gap, on the other hand, seems to have widened in the 21st century. Limiting the analyses to the gainfully employed respondents only reduces the religious attendance gap. For the high earners, the attendance gap effectively disappears, while a large unaffiliation gap persists into the 2010s. This pattern is best explained by the recent literature asserting that men and women are differentially socially sanctioned for the adoption of a secularized identity. The alleged sexism of the new secular movements is also noted as a potential explanation. The examination of the recent Canadian data on perceived religious and gender discrimination produces evidence congruent with both of these potential explanations. [ABSTRACT FROM AUTHOR]

Floating Catchment Area (FCA) methods are a popular tool to investigate accessibility to public facilities, in particular health care services. FCA approaches are attractive because, unlike other accessibility measures, they take into account the potential for congestion of facilities. This is done by 1) considering the population within the catchment area of a facility to calculate a variable that measures level of service, and then 2) aggregating the level of service by population centers subject to catchment area constraints. In this paper we discuss an effect of FCA approaches, an artifact that we term demand and level of service inflation. These artifacts are present in previous implementations of FCA methods. We argue that inflation makes interpretation of estimates of accessibility difficult, which has possible deleterious consequences for decision making. Next, we propose a simple and intuitive approach to proportionally allocate demandand and level of service in FCA calculations. The approach is based on a standardization of the impedance matrix, similar to approaches popular in the spatial statistics and econometrics literature. The result is a more intiuitive measure of accessibility that 1) provides a local version of the provider-to-population ratio; and 2) preserves the level of demand and the level of supply in a system. We illustrate the relevant issues with some examples, and then empirically by means of a case study of accessibility to family physicians in the Hamilton Census Metropolitan Area (CMA), in Ontario, Canada. Results indicate that demand and supply inflation/deflation affect the interpretation of accessibility analysis using existing FCA methods, and that the proposed adjustment can lead to more intuitive results.

Freely-available satellite data streams and the ability to process these data on cloud-computing platforms such as Google Earth Engine have made frequent, large-scale landcover mapping at high resolution a real possibility. In this paper we apply these technologies, along with machine learning, to the mapping of peatlands–a landcover class that is critical for preserving biodiversity, helping to address climate change impacts, and providing ecosystem services, e.g., carbon storage–in the Boreal Forest Natural Region of Alberta, Canada. We outline a data-driven, scientific framework that: compiles large amounts of Earth observation data sets (radar, optical, and LiDAR); examines the extracted variables for suitability in peatland modelling; optimizes model parameterization; and finally, predicts peatland occurrence across a large boreal area (397, 958 km2) of Alberta at 10 m spatial resolution (equalling 3.9 billion pixels across Alberta). The resulting peatland occurrence model shows an accuracy of 87% and a kappa statistic of 0.57 when compared to our validation data set. Differentiating peatlands from mineral wetlands achieved an accuracy of 69% and kappa statistic of 0.37. This data-driven approach is applicable at large geopolitical scales (e.g., provincial, national) for wetland and landcover inventories that support long-term, responsible resource management.

Background: This study reports on physicians’ experiences with chronic pain management. For over a decade prescription opioids have been a primary treatment for chronic pain in North America. However, the current opioid epidemic has complicated long-standing practices for chronic pain management which historically involved prescribing pain medication. Caring for patients with chronic pain occurs within a context in which a growing proportion of patients suffer from chronic rather than acute conditions alongside rising social inequities. Methods: Our team undertook an ethnographic approach known as institutional ethnography in the province of Ontario, Canada in order to explore the social organization of chronic pain management from the standpoint of primary care physicians. This paper reports on a subset of this study data, specifically interviews with 19 primary care clinicians and 8 nurses supplemented by 40 hours of observations. The clinicians in our sample were largely primary care physicians and nurses working in urban, rural and Northern settings. Findings: In their reflections on providing care for patients with chronic pain, many providers describe being most challenged by the work involved in helping patients who also struggled with poverty, mental health and addiction. These frustrations were often complicated by concerns that they could lose their license for inappropriate prescribing, thus shifting their work from providing treatment and care to policing their patients for malingering and opioid abuse. Interpretation: Our findings show that care providers find the treatment of patients with chronic pain–especially those patients also experiencing poverty–to be challenging at best, and at worst frustrating and overwhelming. In many instances, their narratives suggested experiences of depersonalization, loss of job satisfaction and emotional exhaustion in relation to providing care for these patients, key dimensions of burnout. In essence, the work that they performed in relation to their patients’ social rather than medical needs seems to contribute to these experiences. Their experiences were further exacerbated by the fact that restricting and reducing opioid dosing in patients with chronic pain has become a major focus of care provision. [ABSTRACT FROM AUTHOR]

The paper analyzes bid-ask spreads on the Toronto Stock Exchange (TSE) and compares them to those of the New York Stock Exchange (NYSE). Pricing data were compiled for a total of 177 TSE stocks from December 1 to December 13, 1971. Comparisons with NYSE pricing data from previous studies reveal spreads to be wider and marketability services as a whole more costly on the TSE. Possible explanations include structural differences between the two markets, as well as the differing roles of NYSE specialists and TSE registered traders.

The ongoing COVID-19 pandemic has disrupted global economic activity in all sectors, including forest industries. Changes in demand for forest products in North America over the course of the pandemic have affected both primary processors and downstream industries reliant on residues, including wood pellet producers. Wood pellets have become an internationally traded good, mostly as a substitute for coal in electricity generation, with a significant proportion of the global supply coming from Canadian producers. To determine the effect of the COVID-19 pandemic on the Canadian wood pellet industry, economic and market data were evaluated, in parallel with a survey of Canadian manufacturers on their experiences during the first three waves of the pandemic (March 2020 to September 2021). Overall, the impact of the pandemic on the Canadian wood pellet industry was relatively small, as prices, exports, and production remained stable. Survey respondents noted some negative impacts, mostly in the first months of the pandemic, but the quick recovery of lumber production helped to reduce the impact on wood pellet producers and ensured a stable feedstock supply. The pandemic did exacerbate certain pre-existing issues, such as access to transportation services and labour availability, which were still a concern for the industry at the end of the third wave in Canada. These results suggest that the Canadian wood pellet industry was resilient to disruptions caused by the pandemic and was able to manage the negative effects it faced. This is likely because of the integrated nature of the forest sector, the industry's reliance on long-term supply contracts, and feedstock flexibility, in addition to producers and end-users both being providers of essential services.

Sexual and gender-based violence (SGBV) is a highly prevalent issue, both in North America and globally, with well-recognized adverse impact on survivors' physical, emotional, and economic well-being. The objective of this systematic review is to collect and synthesize empirical work on the effects of SGBV victimization on educational trajectories, goals, attainment, and outcomes. The review summarizes what is known about factors associated with victimization that affect survivors' educational trajectories and highlights gaps in the literature pertaining to the effects of victimization on education. Five databases were searched for this review: Web of Science, Sociological Abstracts, PubMed, APA PsycInfo, and ERIC. For inclusion, the articles must present research on the academic impact of any form of SGBV experienced in higher education and must have been conducted in the United States or Canada. The 68 studies that met these criteria presented research on six key areas of educational outcomes: impacts on academic performance and motivation; attendance, dropout, and avoidance; changes in major/field of study; academic disengagement; educational attitudes and satisfaction; and academic climate and institutional relationships. Research also revealed factors mediating the relationship between SGBV exposure and educational outcomes such as mental health, physical health, social support, socioeconomic status, and resiliency, which we summarize in a pathway model. The research reviewed had significant limitations, including weak study designs, limited generalizability, and diversity concerns. We offer recommendations for future research on this topic.

Simple Summary: The European corn borer (Ostrinia nubilalis) is a major pest of corn, managed successfully in North America since 1996 with transgenic Bt-corn. However, practical field resistance and early-warning increases in frequency of resistance genes for all available insecticidal Bt proteins expressed in corn were detected recently at several locations in Canada. Given the high mobility of moths, design of containment and mitigation measures would have to be implemented at large spatial scales around a resistance hotspot to be successful. Effective strategies must account for high gene flow consistent with improved understandings of this species' complex movement ecology, including migratory behavior. The European corn borer (Ostrinia nubilalis, Hübner) has been managed successfully in North America since 1996 with transgenic Bt-corn. However, field-evolved resistance to all four available insecticidal Bt proteins has been detected in four provinces of Canada since 2018. Evidence suggests resistance may be spreading and evolving independently in scattered hotspots. Evolution and spread of resistance are functions of gene flow, and therefore dispersal, so design of effective resistance management and mitigation plans must take insect movement into account. Recent advances in characterizing European corn borer movement ecology have revealed a number of surprises, chief among them that a large percentage of adults disperse from the natal field via true migratory behavior, most before mating. This undermines a number of common key assumptions about adult behavior, patterns of movement, and gene flow, and stresses the need to reassess how ecological data are interpreted and how movement in models should be parameterized. While many questions remain concerning adult European corn borer movement ecology, the information currently available is coherent enough to construct a generalized framework useful for estimating the spatial scale required to implement possible Bt-resistance prevention, remediation, and mitigation strategies, and to assess their realistic chances of success.

The intensity and frequency of extreme rainfall events have increased in North America and the world due to climate change. Extreme rainfall events, characterized by a heavy volume of rainfall in a short duration, have triggered the onset of urban flash floods. Over the years, flash flooding has been reported in different cities in Canada, which resulted in many losses. Subsequently, different green roofing systems have been adopted to control urban stormwater runoff as part of Nature-Based Solutions (NBS) to mitigate urban flood and build a flood-resilient city. Currently, no specific widely recognized standard or code is dedicated to determining the hydrological performance of green roofs as a whole system. Moreover, there are no test protocols to regulate the design of green roof systems in the market. A comprehensive literature review examines existing research methods adopted to evaluate influencing parameters affecting the hydrological performance of NBS-CR. The results indicate several limitations in experimental and field investigations. Consequently, to address these limitations, it is essential to formulate a multi-functional work plan to develop a standardized test method that can become a common platform for the roofing industry to test and quantify the hydrological performance of their systems.

Bernhard and Young (Journal of Academic Ethics, 7, 175-191, ) allege that a 'myth of confidentiality' plagues research in North America because of the absence of statute-based legal protections and the requirements of some REBs to limit confidentiality 'to the extent permitted by law.' In this commentary we describe statute-based protections for research confidentiality available in the United States, clarify the legal situation regarding research confidentiality in Canada, and explain that REBs that 'require' confidentiality to be limited by law are imposing a doctrine that is not required by the TCPS and may violate researchers' academic freedom. The paper laments how excessive REB risk aversion and inaction by the granting agency Presidents has created a situation where some REBs are encouraging researchers to download research risks to research participants and forcing researchers to choose between exposing themselves to the prospect of going to jail to protect confidentiality, watering down their research objectives, or conducting 'vanilla' research rather than engaging in controversial and/or sensitive areas of study. The paper urges the granting agency Presidents to seek legislative change to protect research participants who provide information that could cause them harm if their identity were to be revealed.

This paper analyzes the evangelizing process commenced by the Roman Catholic missionaries established along the Atlantic coasts of Canada from the beginning of the seventeenth century until the first decade of the eighteenth century. Paying particular attention to the case of Acadia, it demonstrates how the effects of the Anglo-French dispute over North America affected missionary results in the Atlantic region. Chronologically arranged, the paper also examines the manner in which, beyond the impact of political factors, the evangelizing activity was affected by a paucity of resources, inconsistencies in the number of missionaries deployed, and poor levels of co-operation between the various religious orders present. Furthermore, it emphasizes that the flimsiness of the missionaries' links to their hierarchical authorities was crucial to the outcome of their activities in the Atlantic region, and that this operational difficulty was compounded by the progressive disengagement of the papal curia from the French missionary framework as the influence of the Gallican church rose.
