The current strategy reports a simple, rapid and precise paper spray ionization mass spectrometry method for trace determination of lutein in matrices of different complexities. The established method was based upon optimization of the applied, cone and RF voltages and mobile phase. Under the optimized parameters, a linear concentration range (1.0–50 μg/g) of lutein was successfully achieved with low limits of detection (3σ/ b) and quantification (10σ/ b) of 0.5 and 1.665 μg/mL, respectively. The proposed method was successfully applied for trace determination of lutein residues in fresh and commercial foods (green and black tea, and tomato paste) purchased from local markets in Canada. The measured concentration of lutein in green bean was 2.76 ± 0.11 μg/g while the highest level (51.5 ± 0.05 μg/g) of lutein was found in the mint stems. • A rapid and low cost paper spray ionization mass spectrometry protocol for lutein analysis was developed. Ii. An acceptable accuracy and recovery for lutein assay have been achieved. Ii. Excellent lower limits of detection (0.50 μg/mL) and quantification (1.67 μg/mL) were achieved. Iv. The proposed PSI/MS protocol was successfully applied for analysis of lutein in food stuffs. [ABSTRACT FROM AUTHOR]

Abstract: Anadramous Atlantic salmon (Salmo salar L.) returning to Exploits River, Newfoundland, Canada, to spawn encounter low concentrations of thermomechanical pulp (TMP) effluent as they migrate upstream past an integrated newsprint mill. Various physiological responses of adult Atlantic salmon from the Exploits River were studied under laboratory conditions. The effects of a 6-h exposure to 0%, 6%, 12%, or 25% (v/v) TMP effluent or an increasing concentration gradient of effluent (0–25%) on cardiac output , critical swimming performance (U crit), hematocrit, and blood glucose, cortisol, lactate, and osmolality were examined. Relative to other treatment groups, during routine and low-level activity was 7–10% higher in fish exposed to at least 12% effluent. The 25% exposure group had a distinctly lower U crit and scope for increase in than the other treatment groups. These findings suggest that effluent exposure elevates physiological maintenance and repair costs, resulting in a reallocation of energetic resources. [Copyright &y& Elsevier]

The impacts of climate change and development present significant challenges and complexities that require new solutions, wise choices, and multi-disciplinary integration. In this context, emotional intelligence (EI) plays a crucial role. However, traditional engineering education and practice overlook the importance of understanding and managing emotions. This research aims to determine the impact of EI as a tool to enhance proactive decision-making and implement sustainable measures within the engineering profession.The study makes three main research contributions. First, it confirms a positive relationship between EI and proactive sustainable decision-making among engineers. This means that engineers with high EI are more likely to consider the impacts of their decisions on various stakeholders and dimensions of sustainability. Second, it suggests that EI can enhance creativity and innovative thinking in engineering, helping engineers to develop effective solutions for challenges related to climate change. Third, the study advocates for incorporating EI training and assessment into engineering curriculums to foster a sustainable and ethical engineering culture. By improving EI, engineers can enhance their interpersonal skills, self-awareness, and emotional management, which in turn can significantly improve teamwork in addressing challenges related to climate change. • Innovative Approach: The paper introduces emotional intelligence (EI) as a novel factor in engineering decision-making for climate change adaptation, which provides a fresh perspective within the realm of sustainable practices. • Relevance to Sustainability: It emphasizes the role of EI in fostering proactive and strategic decision-making, which is crucial for mitigating and adapting to a changing climate, aligning with the journal's focus on sustainable solutions1. • Multidisciplinary Integration: The study bridges engineering, psychology, and environmental science, reflecting the journal's interdisciplinary approach to addressing sustainability challenges. • Practical Implications: By exploring the attitudes of engineers and their decision-making tendencies in relation to EI, the paper offers insights that can lead to targeted interventions, contributing to the journal's aim of promoting sustainable practices. • This paper does not constitute a bibliometric study; rather, it provides empirical research on the impact of EI on sustainable decision-making among engineers.

Stories abound about the devastating effects of Australia's Federation Drought during the early years of the twentieth century. The aim of this paper is to enhance understanding of what is widely regarded as one of the worst droughts on record in Australia by analysing its differentiated spatial impacts across rural New South Wales (NSW). Newspaper articles from the period are first used to provide a spatial disaggregation that suggests varying impacts of the drought by region. In many instances these articles also present a more human narrative of the challenges for those on the land. The paper then investigates the spatial differences further using archival and quantitative methods. First, county-level data on wheat production from the NSW Statistical Register have been assembled. These data facilitated the assessment of the spatial impact of the drought by generating a drought index for each of the forty-three counties, from which a contour map has been produced. Second, statistical information has been collected from the Annual Reports of the NSW Railway Commissioners which recorded wheat cargoes across the state's inland regional rail network. This in turn enabled assessment of the spatial impact of the drought by means of a second contour map based on ninety-one railway stations. In combination, these methods provide a richer picture, and a more detailed and precise understanding of the uneven geography of the Federation Drought of 1895–1903. [ABSTRACT FROM AUTHOR]

This paper investigates the relative importance and effect of conventional and unconventional Canadian monetary policy surprises on housing prices. Using a credible approach to identify structural monetary policy shocks in Canada and a comprehensive Bayesian VAR model to analyze their effects on financial and macroeconomic variables, we find that both conventional monetary policy and quantitative easing shocks have a significant and persistent effect on housing prices in Canada. However, the inflationary effect of a quantitative easing shock is more pronounced than that of an easing target monetary policy surprise. Specifically, the peak effect of a 25-basis point expansionary conventional monetary policy shock is a 2.30% increase in real housing prices while a comparable quantitative easing surprise leads to a peak of 4.56% increase in real housing prices. We conclude that expansionary monetary policy in various forms has had significant inflationary effects on Canadian housing prices. But quantitative easing surprises stand out as the most prominent contributory factor to the escalating Canadian real estate price. Quantitative easing impact consistently outweighs the effects of forward guidance and conventional monetary policy shocks. • Identifies Canadian monetary policy shocks, both conventional and unconventional. • Analyzes impact on housing prices using Bayesian VAR for new insights. • Quantitative easing (QE) impacts housing prices more than conventional shocks. • A 25bps conventional shock raises housing prices by 2.30%; QE by 4.56%.

Structural Health Monitoring has the potential to enhance the safety and serviceability of our aging infrastructures by detecting anomalies at an early stage. Bayesian Dynamic Linear Models (BDLM) have been shown to be effective at detecting anomalies by extracting structural patterns and latent variables from complex and noisy time series. However, the autoregressive component modelling the stationary prediction errors in most BDLM has a tendency to wrongfully capture patterns that should be attributed to anomalies, and thus hinders their detectability. This paper proposes a new bounded autoregressive (B A R) component, which imposes constraints on the autoregressive latent process with a new mixture Rectified Linear activation Unit. The B A R component is probabilistically verified on synthetic data using a new F1t metric, and is validated using real observations collected on a bridge and on a dam located in Canada. The experimental results demonstrate that the B A R model surpasses the performance of the existing autoregressive component with (1) an improved accuracy at estimating hidden states, (2) an early detection of anomalies, (3) a capacity to detect smaller anomaly magnitudes, and (4) the ability to control the tradeoff between the anomaly detectability and the false alarm rate.

[Display omitted] • Anystis baccarum attacked and fed on smaller phytoseiid predatory mites, but mortality was reduced when A. baccarum was provided with an alternate food source. • Orius insidiosus, Stratiolaelaps scimitus and Delphastus catalinae were rarely attacked by A. baccarum , presumably due to their similarity in size, or limited habitat overlap. • Anystis baccarum was not susceptible to Beauveria bassiana (GHA strain) when exposed to surface residues of conidia on filter paper. A generalist predatory mite, Anystis baccarum (L.), was developed as a new biocontrol agent in Canada, and became commercially available in 2022. Because successful biological control programs in greenhouse crops rely on the release of several natural enemies simultaneously to deal with multiple pest species, this study assessed the interaction of A. baccarum with other commonly used biocontrol agents in laboratory trials. Note that only adult stages were used, because the agents tested are predominantly sold and released as adults. Anystis baccarum killed and consumed the generalist phytoseiid mites, Neoseiulus cucumeris (Oudemans) and Amblyseius swirskii Athias-Henriot; however, the mortality of the phytoseiid mites was reduced when an alternative food, Ephestia kuehniella Zeller eggs, was available. There was no intra-guild interaction between A. baccarum and the soil-dwelling predatory mite, Stratiolaelaps scimitus (Womersley). No statistically significant mortality was observed when Orius insidiosus (Say), a generalist hemipteran, or Delphastus catalinae (Horn), a coccinelid beetle used to control whiteflies, were confined with A. baccarum without alternative food for 24 h. The susceptibility of A. baccarum to the entomopathogenic fungus Beauveria bassiana (Balsamo) GHA strain was evaluated by exposing the mites to conidia in a filter paper bioassay. Differences in mite mortality were not significant across all treatments, and only one case of successful sporulation fungal growth was observed from cadavers recovered in the experiments; similarly, differences in the number of eggs produced were not significant across all treatments. Although the laboratory trials sometimes showed severe predation pressure from A. baccarum on other biocontrol agents, they are likely to be functionally compatible in the greenhouse owing to differences in habitat preferences and availability of other prey (pests) or another food source. Results of the current study provide insights that will enable the development of rational biocontrol programs that include A. baccarum. [ABSTRACT FROM AUTHOR]

Abstract: Sustainable regional management (development) requires an understanding of interactions between the social, economic, and ecological systems within the boundaries of a region. In this paper, application of emergy (an environmental accounting method) for regional planning is discussed through a case study. Emergy (spelled with an “m”) methodology is an environmental accounting technique that evaluates the energy system for the thermodynamics of an open system. Major renewable and non-renewable resource fluxes to a region, including energy, matter, human activities, and money can be converted to emergy by using corresponding transformity functions. As a case study, this paper discusses the emergy accounting of Canada and its provinces with various emergy-based indicators. Moreover, emergy maps were generated in a form of emergy geography. These maps are multi-dimensional illustrations that show resource consumption, emergy per person, and emergy density across Canada under two parameters: (1) the quantities of resources consumed and (2) the location of consumption. Emergy analysis also highlights concentrations of renewable and natural resources in Canada and distinguishes the provinces with the highest resource consumption. Analysis of emergy indicator for Canadian provinces shows that Alberta with the highest EYR (7.35) provides energy to the economy of Canada. However, ELR value of Alberta (8.5) indicates that the province''s current economic approach is not sustainable as it relies mainly on non-renewable emergy inputs (mainly from fossil fuels). ELR of British Columbia and Manitoba indicates that these two provinces created a firm balance between emergy use of renewable and non-renewable resources. The characterizations of regions provided in this paper can be used for future land planning and management both in federal and provincial levels. [Copyright &y& Elsevier]

This is a paper about Alice Ravenhill, an under-scrutinized early twentieth-century colonial settler in British Columbia, Canada. It is also a paper about the relationship and deep connections that I developed with her through archival research, a relationship and set of connections that 1 suggest open new spaces to (re)consider present-day colonial power in British Columbia. Specifically, I propose that 'against the grain' archival readings of BC's past, with an emphasis on finding evidence of resistance to colonial power, can serve to distance the present from the past, thus positioning both contemporary geographies and researchers at work in the province today as existing in a different time and place than those of Alice Ravenhill and other colonial subjects. If, by reading 'along the archival grain' as I attempt to do in this paper, we (particularly those of us who live and work in BC today) instead understand ourselves as deeply and emotionally connected to colonial settlers like Alice Ravenhill, and if we understand their lives and work as similar to our own, there is a chance we might avoid some of their more egregious undertakings.

• A novel algorithm reduces statistical errors in the correlation function matrix. • The new correlation function matrix improves the identification of modal parameters. • Statistical errors in the correlation function matrix are system and time dependent. • The statistical errors create an erratic behavior in the tail region matrix. In operational modal analysis, the correlation function matrix is treated as multiple free decays from which system parameters are extracted. The finite time length of the measured system response, however, introduces statistical errors into the estimated correlation function matrix. These errors cause both random and bias errors that transfer to an identification process of the modal parameters. The bias error is located on the envelope of the modal correlation functions, thus violating the assumption that the correlation function matrix contains multiple free decays. Therefore, the bias error transmits to the damping estimates in operational modal analysis. In this paper, we show an automated algorithm that reduces the bias error caused by the statistical errors. This algorithm identifies erratic behaviour in the tail region of the modal correlation function and reduces this noise tail. The algorithm is tested on a simulation case and experimental data of the Heritage Court Building, Canada. Based on these studies, the algorithm reduces bias error and uncertainty on the damping estimates and increases stability in the identification process. [ABSTRACT FROM AUTHOR]

This paper presents the various tools and data sources in British Columbia (Canada) that can be used by environmental consultants to assess the potential of cross-contamination between shale gas formation fluids and shallow aquifers from hydraulic fracturing and related oil and gas activities. A systematic approach for evaluating the potential of cross-contamination using these data sources is applied to a specific case study at an undisclosed location in the northeastern part of the province. This approach includes defining and then evaluating the basic criteria for assessing the potential of cross-contamination. These criteria are: a leak source; a driving force such as buoyancy or head differential and a leakage pathway. This study has revealed that there is a potential of cross-contamination due to hydraulic fracturing activities and wellbore integrity issues. Wellbore integrity can be compromised by induced seismic events or by unintentional communication with offset hydraulic fractured wells. Induced seismicity is linked to the activity of hydraulic fracturing as well as to the deep disposal of wastewater. • A shale gas database in Canada is investigated for wellbore integrity. • Wellbore leakage and cross-contamination can occur with shale gas extracting wells. • Induced seismicity from hydraulic fracturing and disposal wells can damage wellbores.

The application of road salts for winter de-icing of roadways in cold regions has been demonstrated to increase chloride (Cl) concentrations in nearby surface waters and have a negative impact on aquatic organisms and processes. In addition to toxicity to aquatic organisms, high concentrations of Cl in lakes can alter mixing processes, resulting in prolonged anoxic conditions and associated water quality degradation. Elevated concentrations of Cl in freshwater environments in cold regions is a well-documented phenomenon, but few studies have undertaken a long-term evaluation of the impact of urbanization on lakes. In this paper, nine lakes in the Halifax region of Nova Scotia, Canada, were monitored over 35 years to observe Cl concentrations prior to, during, and after urbanizing development. Cl concentrations were observed to increase in most study lakes over the monitoring period and all nine exhibited seasonal trending in response to winter de-icing activities. Six of the lakes achieved a steady-state Cl level after an initial increase in response to development activities, two are potentially still in transition, and one was unaffected by development activities. Watershed land use was found to be a good predictor of the springtime concentration of Cl and can help to inform decision-making surrounding development activities. When the percent of developed land was 25% or more, the Cl concentrations tended to exceed Canadian freshwater quality guidelines for the protection of aquatic life. • Winter road salt application leads to elevated chloride levels in lakes and ponds. • Water bodies were studied over a 35-year period spanning pre- and post-development. • In urbanizing watersheds, lake chloride levels increased by a factor of 8 or more. • Most lakes fluctuate between a spring peak and fall minimum within a narrow range. • Chloride levels exceed water quality guidelines when watershed area is 25% developed.

Indirect adjustment via partitioned regression is a promising technique to control for unmeasured confounding in large epidemiological studies. The method uses a representative ancillary dataset to estimate the association between variables missing in a primary dataset with the complete set of variables of the ancillary dataset to produce an adjusted risk estimate for the variable in question. The objective of this paper is threefold: 1) evaluate the method for non-linear survival models, 2) formalize an empirical process to evaluate the suitability of the required ancillary matching dataset, and 3) test modifications to the method to incorporate time-varying exposure data, and proportional weighting of datasets. We used the association between fine particle air pollution (PM 2.5) with mortality in the 2001 Canadian Census Health and Environment Cohort (CanCHEC, N = 2.4 million, 10-years follow-up) as our primary dataset, and the 2001 cycle of the Canadian Community Health Survey (CCHS, N = 80,630) as the ancillary matching dataset that contained confounding risk factor information not available in CanCHEC (e.g., smoking). The main evaluation process used a gold-standard approach wherein two variables (education and income) available in both datasets were excluded, indirectly adjusted for, and compared to true models with education and income included to assess the amount of bias correction. An internal validation for objective 1 used only CanCHEC data, whereas an external validation for objective 2 replaced CanCHEC with the CCHS. The two proposed modifications were applied as part of the validation tests, as well as in a final indirect adjustment of four missing risk factor variables (smoking, alcohol use, diet, and exercise) in which adjustment direction and magnitude was compared to models using an equivalent longitudinal cohort with direct adjustment for the same variables. At baseline (2001) both cohorts had very similar PM 2.5 distributions across population characteristics, although levels for CCHS participants were consistently 1.8–2.0 μg/m3 lower. Applying sample-weighting largely corrected for this discrepancy. The internal validation tests showed minimal downward bias in PM 2.5 mortality hazard ratios of 0.4–0.6% using a static exposure, and 1.7–3% when a time-varying exposure was used. The external validation of the CCHS as the ancillary dataset showed slight upward bias of −0.7 to −1.1% and downward bias of 1.3–2.3% using the static and time-varying approaches respectively. The CCHS was found to be fairly well representative of CanCHEC and its use in Canada for indirect adjustment is warranted. Indirect adjustment methods can be used with survival models to correct hazard ratio point estimates and standard errors in models missing key covariates when a representative matching dataset is available. The results of this formal evaluation should encourage other cohorts to assess the suitability of ancillary datasets for the application of the indirect adjustment methodology to address potential residual confounding. • Indirect adjustment can be reliably applied to survival models. • Direction and magnitude of confounding is data and model specific. • Formal evaluation of ancillary matching data is critical to assess adjustment bias.

Climate change poses risks to coastal cities due to sea-level rise and changes in storm surge. Using the contingent valuation method and payment card format, this paper seeks to estimate residents of Halifax Regional Municipality's willingness to pay (WTP) for protection from flooding impacts from storm surge. The contribution of this study is the application of this method in a previously unstudied region, to understand individuals' perception of risk and WTP to avoid damage, in order to inform policy aimed at protecting against damage due to sea-level rise and storm surge. WTP is estimated without and with the expectation of future climate change, and also for public vs. private goods. Data is analyzed and compared using OLS, Heckman two-step and Tobit Interval regression models. Results suggest that on average, WTP is roughly $12 per month per household over a ten-year period without the expectation of climate change, and roughly $13 per month per household assuming climate change will have negative impacts in the region. Individuals are most often willing to pay to protect against damages to public infrastructure, as well as power outages. Income and education do not play a major role in individuals WTP. Vulnerability to flooding and level of concern related to risky events have a statistically significant impact on WTP in all models, and gender and age have an impact on WTP in some models. • Willingness to pay (WTP) for protection from flooding is estimated in Halifax, Canada. • WTP is estimated without and with the expectation of future climate change. • Data is analyzed using OLS, Heckman two-step and Tobit Interval regression models. • WTP is roughly $12–13 per month per household over a ten-year period. • Vulnerability to flooding and concern related to risky events have an impact on WTP.

The use of biomonitoring data as an indicator of national levels of human exposure to environmental chemicals has grown in importance and prevalence. Nationally representative urinary bisphenol A (BPA) data are now available for Canada, the United States and Korea. Here we address the following questions: Are urinary BPA data from these countries comparable? What can be discerned regarding geographic and/or temporal similarities or differences? Are there generalizable lessons to be learned regarding comparison of biomonitoring results from different countries? We examined underlying methods and resultant urinary BPA data from national surveys of three countries: Canada (Canadian Health Measures Survey, CHMS, 2009-2015); United States (National Health and Nutrition Examination Survey, NHANES, 2009–2014); and Korea (Korean National Environmental Health Survey, KoNEHS, 2009–2014). We estimated BPA daily intakes on both a volume- and creatinine-adjusted basis. The three countries use similar methods for analyzing urine samples for BPA and participate in external proficiency testing with acceptable results. Field blanks are only used in the CHMS program. There were program-specific differences in fasting times of participants. Median urinary BPA levels in Canada remained relatively constant over the three cycles (1.1–1.2 ng/ml), while US levels decreased (from 1.9 to 1.3 ng/ml) and Korean levels increased (from 0.7 to 1.1 ng/ml) over similar time periods. The most recent survey year data indicate that levels do not differ substantially across countries. Canadian urinary BPA levels have been stable; the subtle, non-significant decrease in intakes may be due to higher body weight in the more recent Canadian surveys. In contrast, the decrease in intakes in the US appears to be due to decreases in urinary BPA as body weights in the US have been stable. Estimated 95th percentile intakes are over an order of magnitude below current health-based guidance values. Our assessment of urinary BPA data from Canada, the US and Korea indicates that methodological differences, methods for dilution adjustment, and population characteristics should be carefully considered when interpreting biomonitoring data. Despite the plethora of publications describing issues with use of creatinine levels for urinary dilution adjustment, there have been no major methodological advances that would assist in interpreting urinary chemical data. A combination of biomonitoring and traditional exposure assessment approaches may be needed to fully assess human exposures to BPA and other chemicals. National biomonitoring surveys provide important information on population levels of chemicals such as BPA and can assist in understanding temporal and geographic similarities, differences, and trends. However, caution must be exercised when using these data to draw anything but broad conclusions, due to both intercountry methodological differences and factors affecting urinary chemical levels that are still poorly understood. While the issues raised in this paper do not appear to be a major concern specifically for the national-scale monitoring of BPA described here, they must be considered when comparing data for other chemicals measured as part of both national and smaller-scale biomonitoring-based research as well as for BPA data from other studies. Image 1 • Urine BPA levels were compared for Canada, US, Korea populations with national data. • Geographic and temporal trends were explored for the 3 countries from 2009 to 2014. • Methodological differences and population characteristics were examined. • Similar BPA concentrations and intakes were observed among the three countries. • Estimated intakes are over an order of magnitude below health-based guidance values.

This paper provides an overview of the emerging role of Aboriginal people in Sustainable Forest Management (SFM) in Canada over the past decade. The 1996 Royal Commission on Aboriginal Peoples (RCAP) provided guidance and recommendations for improving Aboriginal peoples'' position in Canadian society, beginning with strengthening understanding and building relationships between Aboriginal and non-Aboriginal parties. This paper explores the extent to which advances in Aboriginal/non-Aboriginal relationships and Aboriginal forestry have been made as a result of RCAP's call for renewed relationships based on co-existence among nations. Such changes have begun to alter the context in which Aboriginal/non-Aboriginal relationships exist with respect to SFM. While governments themselves have generally not demonstrated the leadership called for by RCAP in taking up these challenges, industry and other partners are demonstrating some improvements. A degree of progress has been achieved in terms of lands and resources, particularly with co-management-type arrangements, but a fundamental re-structuring needed to reflect nation-to-nation relationships has not yet occurred. Other factors related to increasing Aboriginal participation in SFM, such as the recognition of Aboriginal and treaty rights, are also highlighted, along with suggestions for moving Aboriginal peoples'' SFM agenda forward in the coming years.

Abstract: Based on Geographic Information Systems (GIS) analysis, this paper assesses the defensibility of winter village sites in the Mid-Fraser region on the Canadian Plateau during the Late Prehistoric Period (ca. 3500–200 B.P.), particularly the Plateau and Kamloops Horizons (ca. 2400–200 B.P.). Although there is variability in prehistoric village locations in terms of defensibility, highly defensible prehistoric sites in the Mid-Fraser region are concentrated in two localities. The high defensive values of these village sites indicate that the threat of intergroup conflict had a significant impact on choice of settlement location. The approach used in this paper demonstrates the importance of past defensive considerations in the decision making processes pertaining to settlement locations. As conflict is a common feature of many cultures and time periods throughout the world, this approach has potential applications to other defensive sites globally. [Copyright &y& Elsevier]

Abstract: This paper considers Frobisher Bay and Inuvik, two Canadian Arctic towns, as examples of the high-modernist planning that swept the globe during the middle decades of the twentieth century, but also Cold War projects reflecting a sudden interest in the Arctic as a region of military significance. Building on the framework provided by James Scott in Seeing like a State (1998), the paper details the connections between modernization theory and Cold War militarism before turning to the strikingly parallel case studies. In each instance, federal officials proposed ambitious urban models designed to simultaneously overcome the hostility of a northern environment and catapult native northerners into conditions of modern living. While the limits and failings of such schemes varied by location, both sites were also laboratories for social scientists employed by the federal government to document and analyze the modernization of the Arctic. The work of these scholars represents a particularly rich and complex record of governmental interventions, tied variously to Cold War imperatives, in northern lives and landscapes at a time of great faith in the transformative power of modern engineering.

There are acknowledged difficulties in epidemiological studies to accurately assign exposure to air pollution for large populations, and large, long-term cohort studies have typically relied upon data from central monitoring stations. This approach has generally been adequate when populations span large areas or diverse cities. However, when the effects of intra-urban differences in exposure are being studied, the use of these existing central sites are likely to be inadequate for representing spatial variability that exists within an urban area. As part of the Border Air Quality Strategy (BAQS), an international agreement between the governments of Canada and the United States, a number of air health effects studies are being undertaken by Health Canada and the US EPA. Health Canada''s research largely focuses on the chronic exposure of elementary school children to air pollution. The exposure characterization for this population to a variety of air pollutants has been assessed using land-use regression (LUR) models. This approach has been applied in several cities to nitrogen dioxide (NO2), as an assumed traffic exposure marker. However, the models have largely been developed from limited periods of saturation monitoring data and often only represent one or two seasons. Two key questions from these previous efforts, which are examined in this paper, are: If NO2 is a traffic marker, what other pollutants, potentially traffic related, might it actually represent? How well is the within city spatial variability of NO2, and other traffic-related pollutants, characterized by a single saturation monitoring campaign. Input data for the models developed in this paper were obtained across a network of 54 monitoring sites situated across Windsor, Ontario. The pollutants studied were NO2, sulfur dioxide (SO2) and volatile organic compounds, which were measured in all four seasons by deploying passive samplers for 2-week periods. Correlations among these pollutants were calculated to assess what other pollutants NO2 might represent, and correlations across seasons for a given pollutant were determined to assess how much the within-city spatial pattern varies with time. LUR models were then developed for NO2, SO2, benzene, and toluene. A multiple regression model including proximity to the Ambassador Bridge (the main Canada—US border crossing point), and proximity to highways and major roads, predicted NO2 concentrations with an R 2=0.77. The SO2 model predictors included distance to the Ambassador Bridge, dwelling density within 1500m, and Detroit-based SO2 emitters within 3000m resulting in a model with an R 2=0.69. Benzene and toluene LUR models included traffic predictors as well as point source emitters resulting in R 2=0.73 and 0.46, respectively. Between season pollutant correlations were all significant although actual concentrations for each site varied by season. This suggests that if one season were to be selected to represent the annual concentrations for a specific site this may lead to a potential under or overestimation in exposure, which could be significant for health research. All pollutants had strong inter-pollutant correlations suggesting that NO2 could represent SO2, benzene, and toluene. [Copyright &y& Elsevier]

Many firms generate large amounts of carbon dioxide and other greenhouse gases when they burn fossil fuels in their production processes. In addition, production of raw materials and other inputs the firms procure for their operations also generates greenhouse gases indirectly. These direct and indirect greenhouse gas emissions occur in many sectors of our economies. In this paper, we first present sector-specific estimates for such greenhouse gas emissions. We then show that estimates for such sector-specific greenhouse gas emissions are often required for various types of corporate as well as public policy analyses in both domestic and international contexts. Measuring greenhouse gas emissions resulting from firms’ multi-stage production processes in a multi-sector context is relevant for policies related to the Kyoto protocol, an international agreement to limit global greenhouse gas emissions. For example, since the protocol allows firms to engage in trading and offsetting of their greenhouse gas emissions across national borders, provided that emissions are correctly measured, the firms can take advantage of such trading schemes by placing their energy-intensive production facilities globally and strategically. We present several case studies which illustrate the importance of this and other aspects of greenhouse gas emissions in firms’ environmental management. We also argue that our modeling and estimation methods based on input–output analyses are suitable for the types of research goals we have in this paper. Our methods are applied to data for Canada and Japan in a variety of environmental management circumstances. [Copyright &y& Elsevier]

Private security is an increasingly ubiquitous phenomenon in Canada and elsewhere, yet it remains an under-researched topic. The work practices of security officers, as against the organizational form of security services or other more “macro”-level topics, is especially ignored in sociology and criminology. This papers addresses those work practices in venues that are also under-researched, namely, enclosed shopping malls. Through open-ended interviews with security officers, security managers, and retail managers at three Canadian shopping malls, it is found that security officers have varied views of youth across different malls, propose different approaches to the patrol of young mall patrons, express views sometimes not anticipated based on the relative “reputation” of the mall at which the officers work, and express views not always consistent with those of their employers. The variety in officers’ perspectives is seen to be, in part, an outcome of the surprisingly brief amount of formal training that the officers receive and the attendant amount of discretion and the “by the ropes” conduct that constitutes the officers’ jobs. The paper proposes that understanding security officers’ work requires that actual, concerted practices are studied and the engagement of the officers themselves is accomplished.

This paper examines social relationships in the early twentieth-century Canadian corporate workplace, focusing on Quebec where the majority of the nation's financial services industry was located. I argue that in the course of building new networks for the flow of information and capital, women and men in the early twentieth-century whitecollar workplace also produced new meanings about work and gender. This paper has two parts. Part one charts an overview of when clerical work feminized in Quebec, drawing on published census data and a 10% sample of the 1901 nominal census of Montreal. Drawing on personnel files and company journals from several Canadian financial institutions, part two explores social rules and mores about contact across differences particularly of gender and religious affiliation in the early twentieth-century white-collar workplace.

Infant mortality is widely recognized as an indicator of poor living conditions. Scholars have identified economic, housing, environmental, and more recently, cultural determinants of infant mortality. Using individual-level data and record linkage this paper documents and explains the geography of infant mortality in Ottawa in 1901. Infant death in Ottawa mirrored the geography of poor living conditions in the city. The poorest and most densely settled community in Ottawa was Lowertown, a mostly French-Canadian part of the city with a disproportionate share of the city's infant deaths. In addition to environmental factors, infant mortality was linked to economic standing. Poorer families in Lowertown were more likely to have one of their infants die than better off families. After controlling for economic standing, however, cultural factors were stronger predictors of infant deaths. French-Canadian families in Lowertown had a greater risk of infant deaths than did families of other backgrounds irrespective of material circumstances. Supporting conclusions drawn elsewhere, this paper suggests that the interaction of particular cultural practices, such as shorter periods of breast-feeding among French-Canadians and a poor sanitary environment, resulted in high infant mortality rates in Ottawa.

• Epilepsy can be burdensome for patients, families, health systems, and society. • Health disparities of people with epilepsy can be worsened by living in rural areas. • Demographics and socioeconomic status drive the poor outcomes, not rurality per se. • Prospective studies with standard definitions of rural are needed. Epilepsy is a leading cause of global disease burden, with people with epilepsy (PWE) experiencing adverse health outcomes related to the psychiatric comorbidities and socioeconomic consequences of the disorder. Rural populations are more likely to be impoverished or uninsured, which could impact health outcomes for rural-dwelling PWE (RPWE). This systematic literature review identified original research studying health disparities and outcomes among RPWE in the United States and Canada to (1) characterize the disparities faced by RPWE and (2) elucidate the effects of these disparities upon clinical outcomes. We performed a systematic search of six electronic databases: Pubmed, Cochrane, PsychInfo, Web of Science, Scopus, and Ovid. Articles considered were original research reports conducted in Canada or the United States before August 2020. A modified Newcastle Ottawa Scale was used to assess the quality of the included studies. Our search returned 2093 articles that examined the health disparities of RPWE, of which six met criteria for this review. Outcome measures of health disparity included in these papers were mortality (2; 33%), use of health resources (2; 33%), and epilepsy prevalence (2; 33%). Only one paper (16%) concluded that RPWE experienced worse health outcomes relative to urban-dwelling PWE, while 5 (84%) found no difference. Our study did not find sufficient evidence that RPWE in the US and Canada experience significant health disparities compared to similar urban populations of PWE. More research using prospective studies and datasets allowing better characterization of rurality is required. [ABSTRACT FROM AUTHOR]

Abstract The LaHave Estuary is polluted with domestic waste delivered via straight pipes. These are to be replaced with septic tanks. The impact of this remediation on the wider biotic community will need to be assessed. Intertidal foraminifera are ideal for mitigation assessment in the LaHave and comparable estuaries, estuary banks supporting small beds of intertidal vegetation. This paper provides a baseline for future comparisons of the total LaHave intertidal benthic foraminiferal assemblage and presents a method applicable to other estuaries. Regarding the LaHave Estuary, any biotic change must be viewed against the backdrop of other pollutants like mercury near the town of Bridgewater. Four 10 cm3 replicates (push cores) were taken at four sites along the estuary's eastern bank: Miller Point Peace Park (MPPP, near Bridgewater), Dayspring, Upper LaHave and East LaHave. A fifth replicate was tested for %C and %N. To constrain altitude, the replicates were taken immediately inland of a zone of the marsh grass Spartina alterniflora , typically among swirl-patterned (cowlicked) S. patens. The washed replicates were picked clean of foraminifera, 3821 being recovered. Recovery comprised only (in rank order of abundance) Entzia macrescens , Trochammina inflata and Miliammina fusca. The number per replicate ranged from 29 (East LaHave) to 816 (MPPP). Scheffé's test following ANOVA showed the mean MPPP foraminiferal density to be significantly different from the other sites, which acted as a group. The most upstream assemblage was dominated by E. macrescens , the most downstream by M. fusca. There were no significant correlations between %C, %N and the mean foraminiferal densities of species. The mean population densities per 10 cm3 of E. macrescens differed between sites, (a) MPPP, (b) Dayspring and Upper LaHave, and (c) East LaHave forming non-overlapping subsets that will need to be monitored separately. Trochammina inflata mean population densities were distinct only at East LaHave. Miliammina fusca population densities presented a peculiar pattern, MPPP and East LaHave forming one group, and the intervening Dayspring and Upper LaHave sites forming another. The transformed mean proportions per site of E. macrescens and T. inflata were not significantly correlated with %C or %N, but those of M. fusca were positively correlated with both. It may be that high trace metal concentrations near Bridgewater are affecting foraminiferal distributions and abundances. This must be taken into account when using the benthic foraminiferal assemblage to assess the impact of the organic pollution remediation. [ABSTRACT FROM AUTHOR]

High religious intermarriage among the religiously unaffiliated is usually interpreted as evidence of religion's minor importance for this group. Between 1981 and 2011, religious intermarriage among the unaffiliated in Canada declined from 38 percent to 21 percent, while the unaffiliated population tripled from 7 percent to 23 percent. This paper examines the role of demographic factors such as increased group size in decreased religious intermarriage among the unaffiliated. Using census and survey data, we estimate probit models of religious intermarriage for unaffiliated men and women. The models include individual and group-level characteristics. Results show that for both sexes, relative group size was the single largest contributor to decreased intermarriage. Increased group size allowed the expression of endogamous or within-group marital preferences among the unaffiliated. This secular endogamy, or preference for within-group marriage among the unaffiliated, represents an increasingly important form of religion-related marriage as the unaffiliated population grows.

Wardens figure centrally as part of the plot in popular culture representations of prisons such as in films (e.g. The Shawshank Redemption ) and television (e.g. Wentworth ). Yet little is known about how wardens are depicted in another form of criminal justice popular culture: the penal history museum. This paper examines representations of wardens observed as part of a study of 45 punishment memorialization sites across Canada. We analyze the symbolism used in these penal history museums, as well as the framing used to curate warden-related objects. Our analysis reveals that positive representations of prison wardens depict them as family-oriented, benevolent men of a strong character, who embody and command respect for authority. We found fewer representations that were critical of warden's work. We conclude by reflecting on the implications of our findings for literature on cultural depictions of penality and justice.

In this paper, we study the impact of Canada’s adoption of protectionist trade policy in 1879 on Canadian welfare. Under the National Policy, the Canadian average weighted tariff increased from 14% to 21%. The conventional view is that this was a distortionary policy that negatively affected Canadian welfare. We argue that this view is incomplete because it ignores general equilibrium effects. Using a multi-industry general equilibrium model with differentiated goods, we show that tariffs’ impact on welfare can potentially be positive, even for small open economies, due to their impact on domestic terms of trade and government revenues. We apply these theoretical insights in a reassessment of the static impact that the National Policy had on Canadian welfare in 1879, using newly compiled granular trade and production data, and newly estimated historically contemporaneous import demand elasticities. Our results suggest that, although a multilateral move to free trade would have resulted in the best welfare outcome for Canadians, the National Policy’s tariff increases actually improved Canadian welfare by approximately 0.15% of GDP in 1879 – an amount equivalent to approximately $2.3 billion 2016 USD.

The paper examines present and possible future forms of participation in the lower courts by laypeople. The lower courts are frequently presented as troubled places concern being expressed about court backlog, overload and the resort to plea-bargaining as in Canada and the U.S. and sometimes over allegations about class bias and prejudice as in England and Wales. The aim of the paper is to study the principle and practice of lay participation in the lower courts of western capitalist societies. It also examines some of the conventional and unconventional responses proposed as solutions to the problems of judicial administration in the lower courts. It also draws up an agenda for research in the area of judicial administration and court organization in which the possibilities for extending lay participation may be further explored. The paper also argues the importance of defending and elaborating upon the notion of lay participation in law in contemporary western societies. The main lessons to emerge from the discussion on the principle and practice of lay representation in the lower courts, seems to be first, that existing forms of lay involvement capture perfectly the perennial tension of attempts "to bridge the gap between efficiency and democracy."

Nanotechnology has increasing applications in numerous markets, particularly in additive processing (3D printing) and manufacturing, which is important for consumer products, medical devices, construction, and general research and development across many other industries. Nanomaterials are desirable in many products due to their unique properties, but those same properties have made evaluating the risk and regulation of these materials challenging. For risk-based regulations, new applications and nanomaterials should be assessed for both human and environmental hazards and exposure to ensure protection. In general, many risk assessments to date have focused on the non-nano versions of chemicals. The lack of guidance on assessing the hazard and exposure of nanomaterials in 3D printing is apparent, and these areas of assessment are actively being evaluated. Industry in most cases will now need to provide specific additional information for assessing the risk of nanomaterials in 3D printing. This review paper focuses on the use of nanomaterials in 3D printing for industrial and manufacturing applications, summarizes the current literature on human health and safety related to 3D printing and inhalation exposure, and the regulations relating to 3D printing in the U.S., Canada, and Europe for this industry. ga1 • Standardization of nano-characterization has led to comprehensive risk assessments. • Therefore, regulations for nanomaterials are becoming more prevalent. • This paper focuses on regulations impacting the nano-additives industry. • Nanomaterial release from 3D printing needs more research. • More information is needed on assessing hazard, exposure and risk.

Best Management Practices and Beneficial Management Practices ("MP") are two ideational elements, that have emerged in water quality literature. This research explores the questions of where has the lesser utilized term 'Beneficial' emerged and why? To answer these questions, articles obtained from the Web of Science by searching keywords "Best MP"/"Beneficial MP" and "Water" are analyzed using bibliometric techniques through VOS Viewer including time trend of publications, and indicators including keywords, disciplines, institutions, geographies, influential authors and journals, and key funders of these two terms. This paper also employs document analysis and semi-structured interviews with key policy stakeholders. Beneficial Management Practices emerged in Canada (although the term was used in a few instances elsewhere) in Canadian government policy documents starting in 2003. The term 'Beneficial' refers to a lesser standard than "Best" and is exclusive to agricultural practices in risk and environmental farm policy; "Best Management Practices" refer to a wider set of practices (in other sectors like mining) utilized by a more substantive and diverse set of institutions (predominately American and significantly populated by universities). Explanations for the emergence of the term include that it is more 'honest,' it allows for more choices and trade-offs, it reflects the strong economic driver of agriculture, and several interviewees referred to it better reflecting the uncertainty of science. While the strength of the agricultural sector in influencing the 'Beneficial' discourse is not surprising, the failure to measure the improvement to the water quality of Beneficial Management Programs and measure policy's effectiveness is noteworthy. • Canadian Prairie water quality has not improved since 1990 despite Beneficial Management Practices. • Economic consideration prevents Beneficial Management Practices' environmental effectiveness. • Failure to measure effectiveness at improving water quality inhibits the effectiveness. • The "Beneficial" conflict foreshadows the politics of their climate change mitigation expansion.

• Using recent Canadian censuses, this paper examines how sexual orientation associates with the patterns of real estate wealth accumulation. • Prior to the legal recognition of same-sex marriage, same-sex households' homeownership rates were between the rates for married and common-law heterosexuals. • Post-legal recognition, a homeownership disadvantage is found for married same-sex couples, which is larger than the gap found for visible minorities. The homeownership disparities associated with sexual orientation have rarely been investigated. Using the Canadian censuses of 2001, 2006, 2016, and the National Household Survey of 2011, this paper examines how sexual orientation associates with the patterns of homeownership. Given the 2005 legal recognition of same-sex marriage in Canada, the data allow for comparing sexual minorities with heterosexuals of the same marital status. The analysis shows that prior to the legal recognition of same-sex marriage, same-sex households' homeownership rates were between the rates for married and common-law heterosexuals. Post-legal recognition, rather similar homeownership rates are found for common-law same-sex and common-law different-sex couples. But, married same-sex households, regardless of sex composition, are found largely less likely to own their residence than married heterosexuals. Non-negligible differences are also found regarding home values and the presence of mortgage. Various explanations are explored. [ABSTRACT FROM AUTHOR]

Converting industrial wastes into value-added building products in an environmental management strategy is a challenging yet vital component of the industrial process. Steel slag (SS), an industrial waste by-product from the steel-making process, is typically disposed of in landfill which consumes land resources and pollutes the environment. This paper explores the possibility of a closed-loop system to convert steel slag into a cement material through carbonation activation, thereby significantly reducing the amount of steel slag waste sent to landfills across Canada. The production of this cementing material can occur next to the steel mill, utilizing steel slag and carbon dioxide collected on-site to fabricate carbon-negative products. To save energy and allow production to be feasible on an industrial scale, ambient pressure (AP) carbonation is developed to reduce carbon emissions while improving their performance. High pressure (HP) carbonation curing and normal hydration (NH) references were also implemented at the same time to justify the application of AP carbonation in reducing CO 2 emission. The results of this study found AP carbonation-activated SS compacts have comparable CO 2 uptake (about 7.5 tons CO 2 /100 tons slag) and mechanically compressive strength values as those subjected to HP carbonation, suggesting that AP could be used to replace HP in carbonation curing to ensure a lower energy input. Additionally, AP seemed to possess as effective carbonation as HP. The studies investigated by multiple techniques including X-ray diffractometer (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopic analysis, and scanning electron microscopy (SEM) aim to identify the microstructure development of carbonated SS paste to assess carbonation results. Developed with life cycle assessment (LCA), environmental impact evaluation shows that AP presents a smaller global warming potential (GWP) value than HP. The comparable CO 2 sequestration, satisfactory engineering properties, enhanced microstructure and lesser environmental impact in AP carbonation confirm the feasibility of replacing high pressure with extremely low pressure to cure concrete products. The use of AP carbonation for cement material created using steel slag reduces carbon emissions, energy usage, and natural resource consumption. • Ambient pressure can be used to replace high pressure in early carbonation curing. • Ambient pressure carbonation can turn steel slag into a clean cementing material. • The production of carbon-negative products can be set next to the steel mill. • Ambient pressure carbonation presents a relatively uniform and effective reaction. • Life cycle assessment confirms ambient pressure carbonation reduces CO 2 emission.

This paper examines consumers' knowledge and lifestyle profiles and preferences regarding two environmentally labeled food staples, potatoes and ground beef. Data from online choice experiments conducted in Canada and Germany are analyzed through latent class choice modeling to identify the influence of consumer knowledge (subjective and objective knowledge as well as usage experience) on environmentally sustainable choices. We find that irrespective of product or country under investigation, high subjective and objective knowledge levels drive environmentally sustainable food choices. Subjective knowledge was found to be more important in this context. Usage experience had relatively little impact on environmentally sustainable choices. Our results suggest that about 20% of consumers in both countries are ready to adopt footprint labels in their food choices. Another 10-20% could be targeted by enhancing subjective knowledge, for example through targeted marketing campaigns. [ABSTRACT FROM AUTHOR]

Canada's abundant and high-quality water resources support a growing human population, as well as thriving industrial and agricultural economies. However, recent intense drought conditions have raised concerns for current water resource availability. Patterns of long-term ground and surface water (GSW) changes, and their response to environmental conditions, land-use dynamics, and socioeconomic changes are not well-understood across this large and diverse country. To address this crucial gap, we identified regions of ground and surface water (GSW) changes in all the Provinces of Canada between 2002 and 2016 from the Gravity Recovery and Climate Experiment (GRACE) and Global Land Data Assimilation System (GLDAS) datasets. We explored the relationships between GSW changes and environmental, socioeconomic, and land-use dynamics over time. We found that all the Provinces of Canada gained a net 4.46 mm Liquid Water Equivalent (LWE) per year, equivalent to a total increase of 66.9 mm LWE. GSW increases were significantly associated with the normalized difference vegetation index and evapotranspiration rates. In contrast, GSW declines were significantly related to deforestation rate, urban expansion, and economic development (median household income). Despite apparent widespread post-drought recovery detected from 2002 to 2016, the rapid GSW declines were also observed in almost all of Western Canada and part of Ontario, amounting to a net loss of 66.13 mm. This indicates that a pronounced drought had emerged. It is anticipated that Canada will be experiencing more frequent and severe droughts under ongoing climate change and increasing demand for water resources. • This paper presents patterns of long-term ground and surface water (GSW) changes. • GSW increases are significantly associated with improvements in environmental conditions. • The rapid GSW declines are observed in parts of Canada since 2013 indicating the presence of a pronounced drought. • Drought in Canada may become more frequent and severe in the future. • Policy makers should adopt sustainable water management strategies to response future challenges.

The dramatic decrease in international trade costs in the second half of the nineteenth century led to a global trade boom. In this paper, we examine the consequences of greater openness to international trade for regional economic activity in a small, open economy during the first era of globalization. Specifically, we provide a quantitative assessment of the role that exposure to globalization played in industrialization in Canada between 1871 and 1891. Greater exposure to globalization leads to faster growth of manufacturing and the greater concentration of industry around entrepôts of trade between Canada and the rest of the world.

Coastal fishery systems in the Arctic are undergoing rapid change. This paper examines the ways in which Inuit fishers experience and respond to such change, using a case study from Pangnirtung, Canada. The work is based on over two years of fieldwork, during which semi-structured interviews (n = 62), focus group discussions (n = 6, 31 participants) and key informant interviews (n = 25) were conducted. The changes that most Inuit fishers experience are: changes in sea-ice conditions, Inuit people themselves, the landscape and the seascape, fish-related changes, and changes in weather conditions, markets and fish selling prices. Inuit fishers respond to change individually as well as collectively. Fishers' responses were examined using the characteristics of a resilience-based conceptual framework focusing on place, human agency, collective action and collaboration, institutions, indigenous and local knowledge systems, and learning. Based on results, this paper identified three community-level adaptive strategies, which are diversification, technology use and fisheries governance that employs a co-management approach. Further, this work recognised four place-specific attributes that can shape community adaptations, which are Inuit worldviews, Inuit-owned institutions, a culture of sharing and collaborating, and indigenous and local knowledge systems. An examination of the ways in which Inuit fishers experience and respond to change is essential to better understand adaptations to climate change. This study delivers new insights to communities, scientists, and policymakers to work together to foster community adaptation. • Assesses adaptation to climate change in fisheries communities. • Examines how indigenous fishers experience and respond to change. • Climate change creates multiple changes in Arctic fisheries systems. • Diversification, technology, and co-management are three adaptive strategies. • Worldviews, institutions, culture, and knowledge systems can shape adaptation.

Both climate and land use changes can influence water quality and quantity in different ways. Thus, for predicting future water quality and quantity trends, simulations should ideally account for both projected climate and land use changes. In this paper, land use projections and climate change scenarios were integrated with a hydrological model to estimate the relative impact of climate and land use projections on a suite of water quality and quantity endpoints for a Canadian watershed. Climatic time series representing SRES change scenario A2 were generated by downscaling the outputs of the Canadian Regional Climate Model (version 4.1.1) using a combination of quantile–quantile transformation and nearest neighbor search. The SWAT (Soil and Water Assessment Tool) model was used to simulate streamflow, nitrogen and phosphorus loading under different climate and land use scenarios. Results showed that a) climate change will drive up maximum monthly streamflow, nitrate loads, and organic phosphorus loads, while decreasing organic nitrogen and nitrite loads; and b) land use changes were found to drive the same water quality/quantity variables in the same direction as climate change, except for organic nitrogen loads, for which the effects of the two stressors had a reverse impact on loading.

Objective This paper explores which of absolute (i.e. densities of "healthy" and "unhealthy" food outlets taken separately) or relative (i.e. the percentage of "healthy" outlets) measures of foodscape exposure better predicts fruit and vegetable intake (FVI), and whether those associations are modified by gender and city in Canada. Methods Self-reported FVI from participants of four cycles (2007-2010) of the repeated cross-sectional Canadian Community Health Survey living in the five largest metropolitan areas of Canada (n = 49,403) was analyzed. Absolute and relative measures of foodscape exposure were computed at participants' residential postal codes. Linear regression models, both in the whole sample and in gender- and city-stratified samples, were used to explore the associations between exposure measures and FVI. Results The percentage of healthy outlets was strongly associated with FVI among men both in Toronto/Montreal (β = 0.012; P < 0.001), and in Calgary/Ottawa/Vancouver (β = 0.008; P < 0.001), but not among women. Observed associations of absolute measures with FVI were either weak or faced multicollinearity issues. Overall, models with the relative measure showed the best fit. Conclusions Relative measures should be more widely used when assessing foodscape influences on diet. The absence of a single effect of the foodscape on diet positions sub-group analysis as a promising avenue for research. [ABSTRACT FROM AUTHOR]

This paper reviews trends in the academic literature on cumulative effects assessment (CEA) of disturbance on forest ecosystems to advance research in the broader context of impact assessments. Disturbance is any distinct spatiotemporal event that disrupts the structure and composition of an ecosystem affecting resource availability. We developed a Python package to automate search term selection, write search strategies, reduce bias and improve the efficient and effective selection of articles from academic databases and grey literature. We identified 148 peer-reviewed literature published between 1986 and 2022 and conducted an inductive and deductive thematic analysis of the results. Our findings revealed that CEA studies are concentrated in the global north, with most publications from authors affiliated with government agencies in the USA and Canada. Methodological and analytical approaches are less interdisciplinary but mainly quantitative and expert-driven, involving modeling the impacts of disturbances on biophysical valued components. Furthermore, the assessment of socioeconomic valued components, including the effects of disturbance on Indigenous wellbeing connected to forests, has received less attention. Even though there is a high preference for regional assessment, challenges with data access, quality, and analysis, especially baseline data over long periods, are hampering effective CEA. Few articles examined CEA – policy/management nexus. Of the few studies, challenges such as the inadequate implementation of CEA mitigation strategies due to policy drawbacks and resource constraints, the high cost of monitoring multiple indicators, and poor connections between scenarios/modeling and management actions were paramount. Future CEA research is needed to broaden our understanding of how multiple disturbance affects forests in the global south and coupled social and ecological systems and their implications for sustainable forest management. • We review cumulative effect assessments of disturbances in forest ecosystems. • The study developed a Python package to automate the search term selection. • We identified 148 peer review and grey literature across 29 countries. • Most studies are located in the global north, and methodologies are expert-driven. • Study should focus on how disturbance affects coupled social and ecological systems.

Deliberation, dialogue and systematic learning are now considered attributes of good practice for organizations seeking to advance sustainability. Yet we do not know whether organizations that span spatial scales and governance responsibilities can establish effective communities of practice to facilitate learning and action. The purpose of this paper is to generate a framework that specifies actions and processes of a community of practice designed to instill collective learning and action strategies across a multi-level, multi-partner network. The framework is then used to describe and analyze a partnership among practitioners of Canada's 16 UNESCO biosphere reserves, and additional researchers and government representatives from across Canada. The framework is a cycle of seven action steps, beginning and ending with reflecting on and evaluating present practice. It is supported by seven characteristics of collaborative environmental management that are used to gauge the success of the partnership. Our results show that the partnership successfully built trust, established shared norms and common interest, created incentives to participate, generated value in information sharing and willingness to engage, demonstrated effective flow of information, and provided leadership and facilitation. Key to success was the presence of a multi-lingual facilitator who could bridge cultural differences across regions and academia-practitioner expectations. The project succeeded in establishing common goals, setting mutual expectations and building relations of trust and respect, and co-creating knowledge. It is too soon to determine whether changes in practices that support sustainability will be maintained over the long term and without the help of an outside facilitator. [ABSTRACT FROM AUTHOR]

Objectives Glycogen storage disease (GSD) types VI and IX are caused by phosphorylase system deficiencies. To evaluate the natural history and long-term treatment outcome of the patients with GSD-VI and -IX, we performed an observational retrospective case study of 21 patients with confirmed diagnosis of GSD-VI or -IX. Methods All patients with GSD-VI or -IX, diagnosed at The Hospital for Sick Children, were included. Electronic and paper charts were reviewed for clinical features, biochemical investigations, molecular genetic testing, diagnostic imaging, long-term outcome and treatment by two independent research team members. All information was entered into an Excel database. Results We report on the natural history and treatment outcomes of the 21 patients with GSD-VI and -IX and 16 novel pathogenic mutations in the PHKA2 , PHKB , PHKG2 and PYGL genes. We report for the first time likely liver adenoma on liver ultrasound and liver fibrosis on liver biopsy specimens in patients with GSD-VI and mild cardiomyopathy on echocardiography in patients with GSD-VI and -IXb. Conclusion We recommend close monitoring in all patients with GSD-VI and -IX for the long-term liver and cardiac complications. There is a need for future studies if uncooked cornstarch and high protein diet would be able to prevent long-term complications of GSD-VI and -IX. [ABSTRACT FROM AUTHOR]

In the wake of the Great Depression, the Canadian government embarked on a stunning reversal in its commercial policy. A key element of its response was the promotion of intra-imperial trade at the Imperial Economic Conference of 1932. This paper addresses whether or not Canada was able to defy gravity and divert trade flows towards other signatories at Ottawa. The results suggest that the conference was a failure from this perspective. Potential sources of this failure include unreasonable expectations about the likely reductions in trade costs and a neglect of key considerations related to certainty and credibility.

Abstract: Decision making in land management can be greatly enhanced if the perspectives of concerned stakeholders are taken into consideration. This often implies negotiation in order to reach an agreement based on the examination of multiple alternatives. This paper describes a spatial web/agent-based modeling system that was developed to support the negotiation process of stakeholders regarding land development in southern Alberta, Canada. This system integrates a fuzzy analytic hierarchy procedure within an agent-based model in an interactive visualization environment provided through a web interface to facilitate the learning and negotiation of the stakeholders. In the pre-negotiation phase, the stakeholders compare their evaluation criteria using linguistic expressions. Due to the uncertainty and fuzzy nature of such comparisons, a fuzzy Analytic Hierarchy Process is then used to prioritize the criteria. The negotiation starts by a development plan being submitted by a user (stakeholder) through the web interface. An agent called the proposer, which represents the proposer of the plan, receives this plan and starts negotiating with all other agents. The negotiation is conducted in a step-wise manner where the agents change their attitudes by assigning a new set of weights to their criteria. If an agreement is not achieved, a new location for development is proposed by the proposer agent. This process is repeated until a location is found that satisfies all agents to a certain predefined degree. To evaluate the performance of the model, the negotiation was simulated with four agents, one of which being the proposer agent, using two hypothetical development plans. The first plan was selected randomly; the other one was chosen in an area that is of high importance to one of the agents. While the agents managed to achieve an agreement about the location of the land development after three rounds of negotiation in the first scenario, seven rounds were required in the second scenario. The proposed web/agent-based model facilitates the interaction and learning among stakeholders when facing multiple alternatives. [Copyright &y& Elsevier]

This article examines the contingent connections between moral regulation and the production of scale in the Canadian city of Halifax, Nova Scotia. In the early twentieth century, a group called the Halifax Local Council of Women (HCW) unveiled an important program of moral regulation. Targeting the lives of the city's children, this program aimed to inculcate moral norms primarily through the reorganization of space, In the interest of morality, the HCW campaigned against various unwholesome spaces in the city and sought to introduce new, more wholesome spaces for the city's children, At first glance, the HCW's program of moral regulation would seem to involve a transfer of women's activities and capacities from the scale of the 'home' to the 'local' scale; rather than caring for children in the home, the HCW would now be caring for them wherever the 'little life unfolds.' A closer examination, however, shows that the local scale was not so much occupied as it was produced by the HCW and its morality program. In tracking the co-production of moral regulation and geographical scale, this paper aims to reveal the spatial conditions through which one group of people seeks to manage the lives of others.

This paper examines collaborative arrangements between Aboriginal peoples and the forest sector across Canada. Using a broad definition of collaboration, we identified 1378 arrangements in 474 Aboriginal communities in all Canadian provinces and territories, except Nunavut. We categorize these collaborative arrangements into five broad types: treaties and other formal agreements; planning and management activities; influence on decision-making; forest tenures; and economic roles and partnerships. Consistent data was available for only the first three types, which showed that close to 60% of Aboriginal communities use each approach. However, this masks significant differences between provinces. For example, economic roles and partnerships are in place in all New Brunswick communities and 74% of communities in British Columbia, but only 12% of Manitoban communities. The proportion of communities that have been involved in participatory processes in forest decision-making (such as advisory committees and consultation processes) is particularly high in Quebec with 88% of communities, but only 32% of communities hold forest tenures. We also find that three-quarters of all communities choose to engage in two or more approaches, despite the demands that this can place upon the time and energy of community members. We finally consider how policy environments in different jurisdictions affect the frequency of certain types of collaboration. This empirical study, and the typology that it demonstrates, can inform policy development for Aboriginal involvement in Canadian forestry and help guide future research into broader issues of collaborative governance of natural resources.

Over the last thirty years, Aboriginal peoples, forestry companies and governments in Canada have developed a wide variety of arrangements and mechanisms aimed at fostering collaboration and establishing an increasing Aboriginal role in managing and harvesting forestlands. This paper seeks to facilitate the analysis and investigation of various forms of collaboration by presenting a typology based upon institutional arrangements and desired outcomes. Development of the typology followed an iterative process of categorisation, description, testing and revision, using scientific and grey literature combined with testing against an ever-widening number of communities; firstly in Quebec, then in six provinces and finally with 474 communities across the country. We identify five principal forms of collaborative arrangement, each with a number of sub-types: treaties and other formal agreements that establish roles and responsibilities; planning and management activities; influence on decision-making; forest tenures; and economic roles. The application and utility of this typology is illustrated through the examples of four communities, each of which is engaged in several different collaborative arrangements. The typology demonstrates the variety of arrangements that are available to encourage Aboriginal involvement in Canada's forest sector while also provided a basis for future work in comparing the benefits of different arrangements or in analysing the effectiveness of policies.

Groundwater is widely used as a source of drinking water in North America. However, it can be contaminated by microbial or chemical agents potentially hazardous to human health. In recent decades, governments have developed better knowledge of groundwater and established measures to protect and preserve the resource. Several studies have shown that relevant information on groundwater might prove very useful for regional planning purposes. However, there is little information on how groundwater information contributes to decision making in urban and regional planning in Canada and the United States. The objective of this study is to explore the level of use of groundwater information for land use planning purposes in Canada and the United States and to identify the factors that may explain why some provinces or states are more proactive than others when it comes to using such data for groundwater protection purposes. This paper presents the results of a survey sent across North America to groundwater information producers. The resulting data from the survey were examined using descriptive analyses and multiple correspondence analysis, and illustrate how groundwater data can be integrated into land planning.

This paper examines the survey and geographic uses of high-altitude photographic images in Canada between the 1880s and the 1960s. While photographic surveying was practiced in the late nineteenth century, it was not until the 1920s that airplanes provided surveyors with a mobile vantage point from which to view and map the earth below, revolutionizing the production of geographical knowledge. Using aerial photographs, photogrammetrists were able to accurately map remote portions of the nation, while photo-interpreters deciphered human settlement patterns and located the resources previously impossible to locate from the ground, I argue that new forms of vision offered through aerial photographs were not only the result of technological development. In surveying at the close of the nineteenth century, between the photograph and the map lay an epistemological gulf: each testified to a different kind of knowledge, and each guaranteed representation by a different framing of objectivity. Combining the two into a new object, the aerial photograph, required new understandings of the relationships between photographic and cartographic ways of seeing, and between technologies, bodies, and truth. As modern Canada increasingly depended on aerial photographs to map and locate resources, geographers positioned themselves as expert readers of these images, thus forming important connections between the practice of geographical seeing and the aims of the state.

Abstract: Salt marshes in the St. Lawrence Estuary are subjected to strong seasonal variations with sub-arctic winter conditions. The present paper explores sedimentary processes in the Pointe-aux-Épinettes marsh during the ice-free period. Currents, waves, suspended sediment, and sedimentation rates have been measured in June, August and October 2009. Vegetation growth was monitored during one year on a monthly basis to understand the seasonal impact on the marsh. Vegetation attenuates currents and waves, but this attenuation changes over the year as vegetation disappears along winter. Results show that suspended sediment transport and deposition are controlled by vegetation, wave height, currents, distance from the marsh edge and distance from sediment sources. Suspended sediment concentrations and sedimentation rates were significantly correlated to wave height, highlighting the importance of waves for sediment resuspension transport. Transport was lowest in August when vegetation was high and wave occurrence low. However, vegetation growth didn''t change fundamentally sediments dynamic of the marsh. Within one tide, an important part of sediment transport is only local within the marsh, as shown by the maximum sedimentation rates occurring near unvegetated areas of the marsh. Data provide a spatial understanding of summer sedimentology on cold climate marshes. [Copyright &y& Elsevier]
