    Although in-school suspensions may be viewed as less severe than out-of-school suspensions, both discipline consequences limit students’ access to learning opportunities and are negatively associated with a range of educational outcomes. Moreover, if sending students out of class perpetuates the same racial disparities as sending them home, this practice does not realize the equity goals of discipline reforms over the last decade. Our study draws on Critical Race Theory and QuantCrit to understand racial discipline gaps across in-school and out-of-school suspensions using data from students and schools in one large district. Results of multilevel regression models indicate similar racial disparities in both suspension types, suggesting neither approach is equitable. These findings illustrate the limits of race-neutral policies in mitigating exclusionary discipline gaps. Addressing the thorny issues that contribute to racial disparities will likely require greater resources for high quality implementation of school-wide culture change initiatives that are explicitly anti-racist

    Objective: To examine injury and concussion rates, mechanisms, locations, and types of injury in Canadian high school male rugby.Design:Prospective cohort study.Setting:High school male rugby.Participants:A total of 429 high school players (2018: n = 225, 2019: n = 256) were recruited from 12 teams in 7 schools in Calgary, Canada.Interventions: None.Main Outcome Measures: Injury surveillance included baseline questionnaires, weekly exposure, and injury reports. Injuries included those requiring medical attention, resulted in time loss and/or inability to complete a session. Concussion was defined as per the fifth Consensus on Concussion in Sport, and all players with a suspected concussion were referred to a study sport medicine physician.Results: A total of 134 injuries were captured, leading to an injury incidence rate (IR) of 57.9/1000 hours [95% confidence intervals (CIs): 45.4-73.8]. Median time loss was 6 days (range: 0-90). Injuries to the head were the most common (40%), followed by shoulder (12%) and ankle (10%). The concussion IR was 22.0/1000 hours (95% CIs: 15.9-30.4), which was the most common injury type (38%), followed by sprain (20%) and strain (15%). Sixty-five percent of injuries occurred in the tackle (ball carrier 35%, tackler 30%) and 76% of concussions (ball carrier 41%, tackler 35%).Conclusions: The rate of injury and concussion in Canadian youth high school male rugby is high, with tackle-related injuries and concussions the most common. Given this, there is a critical need for implementation of prevention strategies, in particular targeting concussion and the tackle event (eg, neuromuscular, tackle training, and law changes).</p

    Injuries and concussions in Female High School Rugby:Prevention is worth a try

    Objectives: To describe injury and concussion rates and mechanisms in female high school rugby players.Design:Two-year prospective cohort study.Setting:High school rugby.Participants: Participants included 214 female High school rugby players (year 1) and 207 female High school players (year 2) from the Calgary Senior High School Athletics Association 2018 and 2019 rugby competition.Intervention: None.Main Outcome Measures: Match and training injury and concussion. Injury definition included any injury resulting in time loss, inability to complete a session, and/or requiring medical attention. Details of reported injuries were collected on injury report forms and validated by a certified athletic therapist on a validated online injury surveillance platform. Exposure hours for players were tracked using paper or virtual weekly exposure forms by team designates.Results: A match incidence rate (IR) = 93.7 injuries/1000 match hours (95% confidence intervals (CI): 78.6-11.7) and training IR = 5.3 injuries/1000 training hours (95% CI: 4.0-6.9) were estimated. The tackle accounted for 109 (70%) match and 37 (44%) training injuries. Tackling was the most frequent mechanism of injury (IR = 37.5 injuries/1000 match hours, 95% CI: 27.5-51.8 and 1.2 injuries/1000 training hours, 95% CI: 0.7-2.4). Sixty-two match concussions (IR = 37.5 concussions/1000 match hours, 95% CI: 26.8-52.3) and 16 training concussions (IR = 1.0 concussions/1000 training hours, 95% CI: 0.7-1.4) occurred. Of 78 reported concussions, 78% for match and 56% for training were physician diagnosed. Tackling was the most frequent mechanism of concussion in matches (IR = 18.1 concussions/1000 match hours, 95% CI:11.4-28.6).Conclusions: Injury and concussion rates in female high school rugby are high. The tackle accounted for the highest proportion of injuries. Prevention strategies (eg, tackle policy change, tackle-training programs, and neuromuscular training) should be explored to increase sport safety.</p

    Differences in injury and concussion rates in a cohort of Canadian female and male youth Rugby Union:A step towards targeted prevention strategies

    Objective: To examine differences in match and training musculoskeletal injury and concussion rates and describe mechanisms of concussion while considering previous playing experience in female and male Canadian high school Rugby Union ('rugby') players. Methods: A 2-year prospective cohort study was completed in a high school league (n=361 females, 421 player-seasons; n=429 males, 481 player-seasons) in Calgary, Canada over the 2018 and 2019 rugby playing seasons. Baseline testing was completed at the start of each season and injury surveillance and individual player participation through session attendance was documented to quantify individual-level player exposure hours. Injury incidence rates (IRs) and incidence rate ratios (IRRs) were calculated using Poisson regression, offset by player exposure hours and clustered by team. Results: Overall match IR for females was 62% higher than males (overall IRR=1.62, 95% CI: 1.20 to 2.18) and the overall training IR was twice as high for females (overall IRR=2.15, 95% CI: 1.40 to 3.32). The female match concussion IR was 70% higher than the males (concussion IRR=1.70, 95% CI: 1.08 to 2.69). Females had a 75% greater tackle-related IR compared with males (IRR=1.75, 95% CI: 1.20 to 2.56). Additionally, female tacklers had a twofold greater rate of injury compared with male tacklers (IRR=2.17, 95% CI: 1.14 to 4.14). Previous playing experience was not associated with tackle-related injury or concussion IRs. Conclusion: The rate of injury and concussion was significantly higher in females within this Canadian high school cohort. These results emphasise the need for development, implementation and evaluation of female-specific injury and concussion prevention strategies to reduce injury and concussion in female youth rugby.</p

    Recent Developments in the UNO MK 3 Process–A Low Cost, Environmentally Benign Precipitating Process for CO2 Capture

    AbstractSubstantial progress in the development of the UNO MK 3 process and it's cost reduction capabilities has been made since previously reported [1]. In particular, the recent results of two pilot plant trials of the process continue to demonstrate and confirm the major features of the UNO MK 3 process:Low overall cost (up to 50% less than the best amines)Multi-impurity capture and production of valuable by-products (no degradation products)Low energy of regeneration (less than 2.5 GJ/T CO2)Low volatility and environmental impact (SOx and NOx converted to fertilizer products)A good fit with existing global potassium markets (no additional potassium required)These new results are groundbreaking in terms of advancing the process; with no major barriers evident for scaling up the process from the current pilot scale (TRL 5) to larger scale demonstration (TRL 6/7) over the next few years
