Anti-Black Racism and Soccer in Canada: Is It Because I’m Black, Ref?

This study critically examines the experiences of members of a sub-Saharan African men’s recreational soccer club with anti-Black racism in a Western Canadian city. Drawing from extensive ethnographic fieldwork, and working at the intersections of Critical Race Theory and Physical Cultural Studies, our analysis focuses on how team members navigate a racial hierarchy that privileges Whiteness and cements their status as outsiders through both overt and subtle forms of racism on the pitch, and the laborious, retraumatizing challenges of “proving” these racist incidents to those in positions of institutional power. We underline the need for anti-racist and anti-oppressive policies and training, and independent judiciaries to monitor and address racist incidents and systemic racism—and its intersections with other forms of oppression—in Canadian sport cultures.

Creating a Gender-inclusive Learning Environment in Spanish Language Classrooms

Non-binary speakers often struggle to describe themselves within the binary gender system of Spanish. This is even more of a challenge for learners of Spanish who are used to describing themselves in English without having to identify their gender. Our study investigates how we can create a more inclusive learning experience in our Spanish language classrooms. To answer our research question, we conducted a needs analysis through the distribution of an online survey and a series of 20-minute interviews with students and instructors of Spanish in Western Canada. Through these methods, we determined what participants already know about gender-neutral and inclusive language, and what they want or need to know to be able to use and teach inclusive language. Participants were also given the opportunity to share their suggestions and ideas as to how to create a more inclusive learning environment. The key findings indicated that both instructors and students need education and training, and access to teaching and learning resources to normalize the use of gender-inclusive language in the Spanish classroom, which in return will help foster a learning space that is inclusive of all students.

Calibrated SoilOptix ® estimates of soil pH and exchangeable cations in three agricultural fields in western Canada – implications for managing spatially variable soil acidity

Spatial variability in soil pH is a major contributor to within-field variations in soil fertility and crop productivity. An improved understanding of the spatial variability of soil pH within agricultural fields is required to determine liming requirements for precision farming. This study with the use of proximal sensors, firstly assessed the spatial pattern of soil pH and how it can be used to determine site-specific, spatially variable lime requirements. Secondly, the effects of soil pH on soil concentrations of nitrate nitrogen (N03-N), phosphorus (P), potassium (K), sulfur (SO4-S), calcium (Ca), magnesium (Mg), soil organic matter (SOM), aluminum (Al), and manganese (Mn) were assessed in three study fields in central Alberta, Canada. Soil pH varied between 4.5 and 7.5 across all field sites. The field-scale coefficient of variation (CV %) for soil pH, Al and Mn ranged between 4.39 and 7.50 %, 7.33–13.72 %, and 7.33–13.72 % across the three sites. The other soil properties showed low, moderate, and high variability, with field-scale CVs ranging between 6.39 and 17.70 % for SOM and 24.33–91.39 % for SO4-S. Soil pH exhibited positive correlations with both Ca and Mg, across all fields. Negative correlations were observed between soil pH and Al across all fields. A principal component analysis (PCA) was performed for all soil parameters and two principal components accounted for 50 %, 54.9 %, and 76.8 % of the total variance in field 1, field 2, and field 3, respectively. Geostatistical semivariance indicated a strong spatial dependence of all chemical parameters across fields. Large regions within a field were strongly acidic (pH < 5.5) and required lime applications ranging from 0 to 6 t ha−1. We conclude that proximal soil sensors can be calibrated to soil properties, enabling variable rate lime recommendations on spatially variable fields for the management of soil acidity.

The Legacy Effect of Mountain Pine Beetle Outbreaks on the Chemical and Anatomical Defences of Surviving Lodgepole Pine Trees.

The recent mountain pine beetle outbreaks have caused widespread mortality among lodgepole pine trees in western North America, resulting in a reduced population of surviving trees. While previous studies have focused on the cascading impacts of these outbreaks on the physiology and growth of the surviving trees, there remains a need for a comprehensive study into the interactions among various physiological traits and the growth in post-outbreak stands. Specifically, the relationship between chemical (primarily terpenes) and anatomical (mainly resin ducts) defences, as well as the allocation of non-structural carbohydrates (NSCs) to support these defence modalities, is poorly understood. To address these gaps, we conducted a field survey of surviving lodgepole pine trees in post-mountain pine beetle outbreak stands in western Canada. Our retrospective analysis aimed at determining correlations between the post-outbreak concentrations of monoterpenes, diterpenes, and NSCs in the phloem and the historical resin duct characteristics and growth traits before and after the outbreak. We detected strong correlations between the post-outbreak concentrations of monoterpenes and historical resin duct characteristics, suggesting a possible link between these two defence modalities. Additionally, we found a positive relationship between the NSCs and the total concentrations of monoterpenes and diterpenes, suggesting that NSCs likely influence the production of these terpenes in lodgepole pine. Furthermore, historical tree growth patterns showed strong positive correlations with many individual monoterpenes and diterpenes. Interestingly, while surviving trees had enhanced anatomical defences after the outbreak, their growth patterns did not vary before and after the outbreak conditions. The complexity of these relationships emphasizes the dynamics of post-outbreak stand dynamics and resource allocations in lodgepole pine forests, highlighting the need for further research. These findings contribute to a broader understanding of conifer defences and their coordinated responses to forest insect outbreaks, with implications for forest management and conservation strategies.

Genome-wide association study of Verticillium longisporum resistance in Brassica genotypes.

Verticillium stripe, caused by Verticillium longisporum, presents an emerging threat to Canadian canola (Brassica napus). Initially detected in Manitoba in 2014, the presence of this pathogen has since been confirmed across western Canada. Infections by V. longisporum can result in yield losses of up to 50%, which is a cause for concern given the susceptibility of most commercial Canadian canola cultivars. The objective of this study was to screen a collection of 211 Brassica genotypes for their reactions to V. longisporum, and to use genome-wide association study (GWAS) to identify single nucleotide polymorphism (SNP) markers for resistance. The plant material consisted of 110 rutabaga (B. napus ssp. napobrassica), 35 canola, 40 Brassica rapa, and 15 Brassica oleracea accessions or cultivars, alongside 11 hosts of the European Clubroot Differential (ECD) set. These materials were screened for resistance under greenhouse conditions and were genotyped using a 19K Brassica SNP array. Three general linear models (GLM), four mixed linear models (MLM), and three GWAS methods were employed to evaluate the markers. Eleven non-commercial Brassica accessions and 9 out of 35 commercial canola cultivars displayed a low normalized area under the disease progress curve (AUDPCnorm.). The non-commercial accessions could prove valuable as potential sources of resistance against V. longisporum. Forty-five SNP markers were identified to be significantly associated with V. longisporum resistance using single-SNP based GWAS analysis. In comparison, haplotype-based GWAS analyses identified 10 to 25 haplotype blocks to be significantly associated with V. longisporum resistance. Between 20% and 56% of QTLs identified by the more conventional single-SNP based GWAS analysis were also detected by the haplotype-based GWAS analysis. The overlapping genomic regions identified by the two GWAS methods present promising hotspots for marker-assisted selection in the future development of Verticillium stripe-resistant canola.

AAC Hassler Canada Western Red Spring wheat

AAC Hassler (PT496) is an early maturing, high yielding, awned and hollow stemmed Canada Western Red Spring (CWRS) wheat (Triticum aestivum L.) cultivar suited to growing conditions in the northern Canadian Prairies. AAC Hassler yielded 8% more than Glenn, 6% more than Parata and 6% more than Carberry in the Parkland Wheat Registration Trials (2019-2021). AAC Hassler matured 4 days earlier than Carberry and had similar maturity as Parata. AAC Hassler had similar height to Glenn and the lodging score was similar to Parata. The test weight of AAC Hassler was 2% lower than the mean of the checks and the thousand kernel weight was similar to Glenn. AAC Hassler had protein content 0.1% higher than Carberry. AAC Hassler expressed an intermediate resistant reaction to Fusarium head blight (FHB; Fusarium graminearum Schwabe). AAC Hassler was moderately resistant to the prevalent races of stem rust (Puccinia graminis Pers. f. sp. tritici Eriks. &amp; E. Henn) and moderately susceptible to common bunt [Tilletia caries (DC) Tul. &amp; C. Tul.]. It was resistant to prevalent races of leaf rust (Puccinia triticina Erikss.) and stripe rust (Puccinia striiformis Westend). AAC Hassler was susceptible to orange wheat blossom midge (OBWM) (Sitodiplosis mosellana Géhin). AAC Hassler was registered under the CWRS class.

Trends in sedimentary Cladocera and metal(loid)s from Williams Lake (Washington, USA) track ∼125 years of trans-boundary contamination from smelter emissions in the upper Columbia River valley

The lead‑zinc smelter at Trail (British Columbia, Canada) has operated continuously for ∼125 years, with long-standing concerns that transboundary metal(loid) and sulphur emissions have contaminated water bodies in both western Canada and Washington (WA), USA. To assess aquatic ecosystems affected by over a century of industrial contamination requires an understanding of pre-smelting conditions. Here, we use a dated sediment core from Williams Lake (WA), downwind of both the Trail and the short-lived LeRoi (Northport, WA) smelters, to track regional contaminant history and other environmental stressors. Specifically, we examine a selection of chemical elements, cladoceran assemblages, visible range spectroscopy-inferred chlorophyll a (VRS-Chl a) and visible near-infrared spectroscopy-inferred lake-water total organic carbon (VNIRS-TOC). Sedimentary proxies recorded the onset of smelting in 1896 CE, peak periods of aerial emissions in the early to mid-20th century, and the history of emission controls. With a few exceptions, sedimentary metal(loid)s exceeded Canadian Interim Sediment Quality Guidelines during the height of the smelting era and have declined substantially since ca. 2000 CE. The loss of metal-sensitive Cladocera and declines in primary production (VRS-Chl a) at the onset of the regional smelting era indicate a strong biological response to airborne industrial contamination. The largest cladoceran change in the sediment record was concurrent with accelerated mitigation efforts at the Trail facilities following the 1960s; however, this compositional shift was between ecologically similar daphniid taxa. Steep declines in VNIRS-TOC concentrations during the period of peak emissions at Trail suggested an increase in sulphur deposition on the landscape that reduced terrestrial carbon supply. However, the persistence of calcium-sensitive daphniids throughout the record indicates that alkaline Williams Lake had not acidified. Current cladoceran assemblages remain substantially distinct from pre-industrial communities, demonstrating how paleoecotoxicological approaches can be used to track the effects of multiple stressors in a temporally appropriate context.

Essential Conditions for Partnership Collaboration within a School-Community Model of Wraparound Support

Children and youth often face barriers that hinder their ability to engage in school, such as poverty, family challenges, and maltreatment. For this reason, children require additional supports if they are to be set up for success in school and life. Collaborative school-community models of wraparound support have been demonstrated as effective approaches for supporting vulnerable children and families to foster positive outcomes. Such models rely on collaborative partnerships between schools and community agencies to coordinate services for children and families. Accordingly, there is a need to understand factors that influence this collaboration in school settings. This study explores partnership collaboration between school and community partners through the case of All in for Youth, a school-based wraparound model of support in western Canada. Focus groups of n = 79 partners across eight schools were analysed, guided by qualitative description methodology. Five essential conditions were identified for partnership collaboration, including value-based training, mutual recognition of expertise, school leadership, established and flexible communication channels, and appropriate staff resources. These conditions can be used to help inform the implementation of similar school-community models of support to foster collaborative partner processes and promote positive outcomes among children, youth, and families.

The Role of the Cardiac Surgery Patient in Pain Management: The Patient Perspective.

One and a half million cardiac surgeries are completed worldwide each year where undertreated postoperative pain increases the risk of patient morbidity and mortality. Patient-centered pain management is recommended to improve patient outcomes but there is insufficient information regarding how the patient views their role. The objective of this study is to explore cardiac surgery patients' perspectives on their role in postoperative pain management. This study used an interpretive phenomenological design and convenience sampling. Six participants who had undergone cardiac surgery were recruited from a cardiac rehabilitation program in Western Canada. The first author conducted semi-structured digitally recorded interviews. Sociodemographic characteristics and measures of anxiety and depression were also collected. Emergent thematic analysis of the qualitative data generated three themes: attitude, coping and care, and communication. The findings of this study address a gap in the literature with regard to patients' perceived roles in pain management. There is a complex relationship between patient attitude, coping and care, and communication which, in turn, influences how patients view their role within the pain management continuum. These themes contribute to the development of the patient role within the pain management continuum and form an integrated feedback loop. The patient's attitude contributes to their ability to cope with pain and participate in pain assessment and management. Furthermore, their ability to cope and desire to participate influences the development of their attitude. These findings may enhance providers' understanding of the patient's perspective and improve pain management outcomes.

Spatial scale of stand-replacing forest disturbance influences the amplitude of snowshoe hare population fluctuations in boreal forests of northwest Canada

The natural disturbance model for ecosystem management of timber harvesting promotes the emulation of natural disturbance regimes in the patterns of tree removal. Wildfire is a prominent natural disturbance in boreal forests of western Canada, frequently removing most of the tree canopy from patches of 500–10,000 ha in stand-replacing events. However, fire suppression, coupled with a spatial pattern of timber harvesting dominated by small patch cuts of 10–160 ha, have changed the spatial scale of younger stands away from scales within which boreal organisms evolved. In two regions (Sub-Boreal Spruce biogeoclimatic zone of central British Columbia and Liard Basin of southeast Yukon), we tested the hypothesis that different spatial scales of stand-replacing forest disturbance (wildfire and timber harvesting) result in different amplitudes of change in abundance of snowshoe hare, a keystone boreal forest mammal for which mid-seral stand conditions provide optimal habitat. Landscapes with large patches (>2000 ha) of mid-seral forest following stand-replacing disturbance supported consistently and often significantly more hares, with wider amplitude in cyclic fluctuation, than small patches (20–200 ha) of mid-seral habitat and than mature forest landscapes. Densities of hares high enough to support reproduction by Canada lynx (a specialist hare predator) only occurred in landscapes disturbed at the scale of a moderate to large-sized wildfire (1000 – 10,000 ha). Landscapes unaffected by stand-replacing disturbance for at least 80 years (i.e. mature forests) supported very few hares and without cyclic fluctuations. We recommend that the recent pattern of cutting dominated by small patches (20–200 ha) be shifted to include many larger patches (2000–5000 ha). This can happen with incremental, contiguous patch cutting over a period of years short enough that the completed patch will supply high quality, mid-seral habitat for at least the period of one hare cycle (10 y). In designing relatively large patches, mature green tree retention would be desirable for various values, but would be best as small stands of mature forest dispersed within large patch cuts, similar to the legacy of fire. Silviculture (reforestation and stand tending) should create and sustain a mix of conifer and deciduous regeneration in the mid-seral stands. Emulating spatial patterns of stand-replacing natural disturbance appears necessary to sustain snowshoe hare cycles when most fires are suppressed in intensively managed western Canadian boreal forests.

Drivers and Impacts of the Record-Breaking 2023 Wildfire Season in Canada.

The 2023 wildfire season in Canada was unprecedented in its scale and intensity, spanning from mid-April to late October and across much of the forested regions of Canada. Here, we summarize the main causes and impacts of this exceptional season. The record-breaking total area burned (~15 Mha) can be attributed to several environmental factors that converged early in the season: early snowmelt, multiannual drought conditions in western Canada, and the rapid transition to drought in eastern Canada. Anthropogenic climate change enabled sustained extreme fire weather conditions, as the mean May-October temperature over Canada in 2023 was 2.2 °C warmer than the 1991-2020 average. The impacts were profound with more than 200 communities evacuated, millions exposed to hazardous air quality from smoke, and unmatched demands on fire-fighting resources. The 2023 wildfire season in Canada not only set new records, but highlights the increasing challenges posed by wildfires in Canada.

Newly Qualified Canadian Nurses' Experiences With Digital Health in the Workplace: Comparative Qualitative Analysis.

Clinical practice settings have increasingly become dependent on the use of digital or eHealth technologies such as electronic health records. It is vitally important to support nurses in adapting to digitalized health care systems; however, little is known about nursing graduates' experiences as they transition to the workplace. This study aims to (1) describe newly qualified nurses' experiences with digital health in the workplace, and (2) identify strategies that could help support new graduates' transition and practice with digital health. An exploratory descriptive qualitative design was used. A total of 14 nurses from Eastern and Western Canada participated in semistructured interviews and data were analyzed using inductive content analysis. Three themes were identified: (1) experiences before becoming a registered nurse, (2) experiences upon joining the workplace, and (3) suggestions for bridging the gap in transition to digital health practice. Findings revealed more similarities than differences between participants with respect to gaps in digital health education, technology-related challenges, and their influence on nursing practice. Digital health is the foundation of contemporary health care; therefore, comprehensive education during nursing school and throughout professional nursing practice, as well as organizational support and policy, are critical pillars. Health systems investing in digital health technologies must create supportive work environments for nurses to thrive in technologically rich environments and increase their capacity to deliver the digital health future.

Evaluating the quality characteristics of intermediate wheatgrass grown in the Canadian prairies

AbstractBackground and ObjectivesIntermediate wheatgrass (IWG) is an underutilized perennial grain in the Canadian market with excellent nutritional and environmental benefits. The aim of this study was to assess the impact of the growing environment on the physiochemical and functional properties of IWG grown in three different growing locations in the Canadian prairies. IWG flours were compared between growing locations and years as well as alongside Canada Western Red Spring Wheat whole meal (CWRS‐WM) and refined flour.FindingsThe proximate composition of IWG flours between years and growing locations had significant (p &lt; .05) differences for protein, fiber, and ash content but showed little difference for starch content. Owing to differences in proximate composition, variances in mixing parameters, starch pasting properties, and protein profiles were observed. Overall IWG performed poorly in a bread system at 100% incorporation largely due to its lack of high molecular weight glutenin.ConclusionUnderstanding the impacts that growing location and year have on the proximate composition and therefore working parameters will aid in the development of new wheat products fortified with IWG. These products will contribute to a more resilient and diverse food system, that will provide nutrient‐dense food options for consumers.Significance and NoveltyThere is very limited research on IWG grown in the Canadian prairies, and this study is among the first studies focused on characterizing IWG grown in Canada.

Molecular detection of Chlamydia abortus in endometrial biopsies of mares from western Canada.

Chlamydia abortus is a reported cause of infertility and endometritis in sheep, cattle, and pigs; however, the association between uterine disease and C. abortus is poorly understood in horses. Recently, a high prevalence of C. abortus in equine aborted chorioallantoises was reported in horses in western Canada. Based on this high prevalence, investigation into the effects of C. abortus on infertility and endometritis in western Canadian mares is prudent. We examined 98 formalin-fixed, paraffin-embedded endometrial biopsies from western Canada submitted between 2014 and 2022 using a Chlamydia-specific 16S rRNA PCR test; 40 samples tested positive for Chlamydia on PCR, and 28 were sequenced as C. abortus. The C. abortus-positive cases were primarily associated with a history of failure to conceive, early embryonic loss, or abortion. Our findings suggest that C. abortus may be a cause of conception failure and abortion in horses in western Canada.

Impacts of Peer Support on Coping and Cortisol Levels for Women Affected by Domestic Violence and Coercive Control.

Gendered domestic violence and coercive control are prevalent public heath concerns in Canada with dire consequences for survivors. Peer support groups may address and reduce negative impacts of domestic violence and coercive control on women's stress, coping, safety, and alliances with social support network members, the focus of this study. A one-group, pre-test/post-test quasi-experimental study was undertaken to evaluate the effectiveness of Growth Circle, a 14-week peer support program offered at an agency serving women affected by domestic violence in a major western Canadian city. Through convenience sampling, women 18 years and older who experienced domestic violence were recruited and provided data on stress, coping, safety-related empowerment, and social support/alliances. Thirty-five participants provided all pre-test and post-test data, with a subsample of 14 providing repeated hair samples. Hair was employed to determine stress hormone (cortisol) levels. A significant reduction in self-reported levels of perceived stress and stress hormone levels following completion of the Growth Circle program was revealed. Participants also reported a significant increase in safety-related empowerment, and supportive alliances with group members. The Growth Circle peer support program was demonstrated to be effective. Further implementation and research into the Growth Circle program across Canada is recommended.
