Inovação na gestão de conflitos do Brasil: a importância da difusão prática e do conhecimento sobre as formas consensuais de resolução de conflitos
Authors: Maia de Morais Sales Lilia , Deibson Lopes Silveira Taffarel
Published: September 2024

O Poder Judiciário é a estrutura de solução de conflitos mais procurada no Brasil. Contudo, existem indícios de que a maioria das ações judiciais poderiam ser resolvidas por formas consensuais de resolução de disputas. Neste cenário, questionam-se as razões pelas quais os Meios Alternativos de Solução de Conflitos (MASCs) ainda não se popularizaram no país. A hipótese inicial reside na falta de conhecimento pela sociedade e pelos profissionais da área jurídica. Assim, objetivamos: compreender o atual contexto da gestão de conflitos judicial e extrajudicial no Brasil; verificar a aplicabilidade das formas de resolução extrajudicial em face das demandas mais recorrentes; auferir o grau de conhecimento da sociedade e a adequada formação dos profissionais do Direito sobre as formas consensuais de resolução; e analisar se há relação entre os MASCs e o aperfeiçoamento da Justiça. Para tanto, nos utilizamos de pesquisa quanti-qualitativa, com revisão bibliográfica e documental, incluindo dados oficiais do Conselho Nacional de Justiça (CNJ), da Associação dos Magistrados do Brasil (AMAB), do World Justice Project (WJP) e das matrizes curriculares de amostra dos Cursos de Bacharelado em Direito. Os resultados confirmaram a hipótese inicial de que falta conhecimento suficiente à sociedade e melhor formação aos profissionais do Direito.

Novel Approach to Interaction Between Engine-Drive Train System and Deformable Rotorcraft Airframes
Authors:   Politecnico di Milano, Muscarello Vincenzo ,   Leonardo Helicopters, Favale Marco , Cocco Luigi , Masarati Pierangelo , Quaranta Giuseppe
Published: September 2024

In this paper a procedure to restore the torque load path between the drive system and the airframe is proposed. The load path is modeled starting from the rotors to the engines, through the drive train system. The torsional loads are transferred to a detailed finite element model of the airframe through connections constraining the gearboxes to the airframe structure. At the same time, the torques generated by the airframe deformations are fed back into the drive system. The procedure to restore the torque load path is firstly validated with a benchmark model, in which the gearboxes are introduced as rigid bodies and connected to the ground by means of elastic springs to represent the airframe elasticity. Overall stability analyses are performed on a complete aeroservoelastic helicopter model to investigate possible aeromechanical phenomena due to airframe and drive train system coupling. A comparison of the results obtained by the classical decoupled approach and the fully coupled approach is presented to highlight cases where significant differences arise between the two approaches.

Authors:   SKF Aerospace, Allison Bryan ,   The Boeing Company, Kozachyn Mark , Lunz Tom , Monaghan Kyle
Published: September 2024

The rotorcraft industry is constantly pushing for higher temperatures, speeds, and loads, while simultaneously minimizing weight. Hybrid bearings (steel rings with ceramic rolling elements) offer improved performance over all-steel bearings plus significant weight savings. However, there are still concerns about using them within the aerospace industry. Two of the main concerns regarding hybrid bearings are that any manufacturing defects may lead to premature failure and that failures may be catastrophic in nature. In this manuscript, recent research performed on the sensitivity of hybrid bearings to preexisting damage and the sensitivity of an engine gearbox to hybrid bearing failure is presented. First, elemental testing was performed on ceramic rolling elements during which it was found that it is difficult to damage a ceramic rolling element and that they are far more tolerant of damage than was previously believed. Next, damaged balls were run in a single ball test rig at operating stresses to determine number of cycles to failure as a function of damage severity and predict time to failure in the application. Finally, the damaged rolling elements were run in a gearbox under maximum normal operating conditions and produced a soft failure within 15% of the time predicted by single ball testing.
The Evolution of Heavy-Lift Operations Performed by Tandem Rotor Helicopters at Columbia Helicopters
Authors:   Columbia Helicopters Inc., Royce Anna , Johnson Elle , Makowski Daniela
Published: September 2024

Columbia Helicopters, Inc. was founded in 1957 by Wes Lematta. Lematta wanted to find a use for helicopters other than transporting people, and with that vision, built a company that spurred the industry of heavy-lift helicopter operations. In the early years of the company, operations included construction and helilogging. Columbia was one of the first successful helilogging companies in the world. In 1969, Columbia purchased its first tandem rotor helicopter, a Boeing-Vertol 107-II. Today, the company's fleet consists entirely of tandem rotor helicopters. Columbia holds the Type Certificates and Parts Only Production Certificates for the Model 107-II and the Model 234. Columbia also owns a Restricted Type Certificate for the Model CH-47D Chinooks. The company uses these three aircraft models to complete a variety of heavy-lift operations including firefighting, logging, government services, construction, stream work, oil and gas exploration, and humanitarian support. As the demands of the industry evolved, so has Columbia, by shifting focus of company operations from helilogging to firefighting and other government services.
Helicopter Flight Procedures for Community Noise Reduction
Authors:   NASA Langley Research Center, Greenwood Eric
Published: September 2024

A computationally efficient, semiempirical noise model suitable for maneuvering flight noise prediction is used to evaluate the community noise impact of practical variations on several helicopter flight procedures typical of normal operations. Turns, "quick-stops," approaches, climbs, and combinations of these maneuvers are assessed. Relatively small variations in flight procedures are shown to cause significant changes to Sound Exposure Levels over a wide area. Guidelines are developed for helicopter pilots intended to provide effective strategies for reducing the negative effects of helicopter noise on the community. Finally, direct optimization of flight trajectories is conducted to identify low noise optimal flight procedures and quantify the magnitude of community noise reductions that can be obtained through tailored helicopter flight procedures. Physically realizable optimal turns and approaches are identified that achieve global noise reductions of as much as 10 dBA Sound Exposure Level.

Authors:   Pennsylvania State ARL, Goldschmidt Margalit ,   Ocean Renewable Power Company, Horn Joseph , Jonson Michael , Medvitz Richard , State Pennsylvania
Published: September 2024

A Marine Hydrokinetic (MHK) cycloturbine is a renewable electric power generation system used in rivers or tidal environments. MHK cycloturbines have foils oriented perpendicular to the flow in a paddlewheel configuration, and use the lift from these foils to produce power. Due to the high cost associated with its operation and maintenance, it was desired to design an MHK system that can self-deploy, with propulsion and control mechanisms similar to a cyclorotor aircraft. This paper investigates different design configurations for such a vehicle, and analyzes the basic force and moment balance required. Computational Fluid Dynamics (CFD) was used to predict cycloturbine efficiency, during both power generation and maneuver. A six-DOF simulation model is being developed, where the turbine propulsive force model is matched to CFD analysis. A four turbine design with stacked counter-rotating turbines was determined to provide the best vehicle control and performance. Future experimental work includes investigation of a single small-scale crossflow turbine to validate the CFD and propulsive force model used in the six-DOF simulation.

A brief summary of the WHO 2021 classification of adult diffuse gliomas
Authors: Lan Tien-Li , Lin Shih-Chieh , Chen Yi-Wei , Lee Yi-Yen
Published: September 2024

The World Health Organization (WHO) classification system for central nervous system (CNS) tumors provides a distinct framework for differentiating these tumors from other types. Notably, gliomas are the most common and clinically significant primary brain tumors. The 2021 update of the WHO classification system (WHO CNS5), building upon the 2016 edition, integrates molecular genetics with histopathological insights to enhance diagnostic precision. This update advocates a multi-layered diagnostic strategy, combining histopathology, WHO grading, and molecular genetics into a unified diagnosis, thus refining the basis for clinical research, trials, and therapeutic interventions. In WHO CNS5, gliomas are categorized into three main groups based on IDH mutation and 1p/19q codeletion status: Diffuse astrocytoma with IDH-mutant, oligodendroglioma with IDH-mutant and 1p/19q-codeletion, and glioblastoma with IDH-wildtype. The diagnostic criteria for adult diffuse gliomas include detailed descriptions of the updated classification, focusing on the molecular markers and histopathological characteristics.
Intravitreal steroid implants in the management of noninfectious intermediate and posterior uveitis
Authors: Shah Sarjak M , Prabhu Priya , Biswas Jyotirmay
Published: September 2024

The management of intermediate and posterior uveitis poses a significant challenge of achieving adequate drug concentrations in the posterior segment over the chronic nature of the disease. Systemic agents seldom reach effective drug levels, and even with low maintenance or tapering doses, it is hard to avoid systemic toxicity. The use of intravitreal and periocular injections is often unable to prevent recurrences due to their short half-life. Since the emergence of intravitreal implants (Vitrasert, Retisert), it has become possible to circumvent these therapeutic challenges. A detailed review in the PubMed index yielded 155 articles, of which 22 were analyzed based on exclusion criteria. A recent shift from surgically sutured to minimally invasive injectable implants mainly indicated for noninfectious uveitis is evident from the literature. This review article also provides insights into dexamethasone (Ozurdex) and recent fluocinolone acetonide (Yutiq, Iluvien) implants with particular emphasis on their improved safety and efficacy. Dexamethasone implants favor the therapeutic goal of prevention of recurrences, whereas the use of fluocinolone implants helps to attain better visual outcomes due to their longer duration of action. Thus, the review provides recent literature supporting the role and indication of sustained release intravitreal implants in the management of noninfectious intermediate and posterior uveitis.

Authors: Pandey Divya Nand , Garg Ravi , Kumar Chandan , Singh Chetan , Gautam Nayank
Published: September 2024

Background:

Anthropometric research on the hip joint has significant clinical implications, including (1) implant design and (2) avoiding implant mismatch complications, such as aseptic loosening and incorrect load distribution, which are mainly unknown in North India. The aim of this research is to ascertain the anatomical differences in the normal hip joint across individuals in North India and to statistically compare the results with global data.

Materials and Methods:

We used one hip topogram and one axial segment of the femoral head to analyze 100 people (35 females and 65 males) with normal hips between the ages of 20 and 65. In both sexes and on both sides, we determined the means of the following measurements: femoral head diameter (HD), femoral neck width (NW), femoral neck length, acetabular angle of sharp, femoral version, horizontal offset, acetabular version, and vertical offset.

Results:

The following are the mean parameters that were observed: (a) neck shaft angle (NSA) - 128.93°, (b) femoral HD = 4.29 cm, (c) femoral NW = 2.97 cm, (d) femoral neck length = 3.61 cm, (e) Acetabular angle of Sharp - 33.01°, (f) Acetabular version = 20.44°, (g) femoral Version = 21.57°, (h) horizontal offset = 3.62 cm, and (i) Vertical offset = 4.43 cm.

Conclusion:

The NSA and acetabular angle of sharp were 5°–6° more when compared to the western population while horizontal and vertical offset is comparatively less than Western population and in the Indian NSA was higher for North Eastern population than the North Indian population. The residual parameters were comparable to those found in Western literature.
A Hardware-in-the-Loop Platform for Developing a Fuel Cell Hybrid Electric Microcar: Fuel Cell Stack Sizing Using a Real-Time Testing Approach
Authors: Bartolucci Lorenzo , Cennamo Edoardo , Cordiner Stefano , Donnini Marco , Grattarola Federico , Mulone Vincenzo
Published: September 2024

Sustainable mobility is a pressing challenge for modern society. Electrification of transportation is a key step towards decarbonization, and hydrogen Fuel Cell Hybrid Electric Vehicles (FCHEVs) offer a promising alternative to Battery Electric Vehicles (BEVs), especially for long-range applications: they combine a battery system with a fuel cell, which provides onboard electric power through the conversion of hydrogen. Paramount importance is then given to the design and sizing of the hybrid powertrain for achieving a compromise between high performance, efficiency, and low cost.

This work presents a Hardware-in-the-Loop (HIL) platform developed for designing and testing the powertrain layout of an FCHEV. The platform comprises two systems: a simulation model reproducing the dynamics of a microcar and a hardware system for the fuel cell hybrid electric powertrain. The former simulates the vehicle's behavior, while the latter is composed of a 2kW real fuel cell stack and a 100Ah Li-ion battery pack. This element is used for real-time testing of the hybrid powertrain, using a programmable power supply that emulates the vehicle and motor load request.

Two fuel cell stack configurations have been analyzed by applying a linear scale-up approach (2kW and 4kW) and tested on an acceleration and deceleration driving cycle, representative of the microcar application; a simple fuzzy logic control strategy has been chosen for the test.

The system's performances have been evaluated and deeply analyzed in terms of component behavior and energy efficiency. The results demonstrate that the 4kW stack configuration scores a nearly 5% higher efficiency than the 2kW stack, mainly operating in the lower current regions corresponding to higher efficiencies. The improvements can then be translated into an increase in the vehicle's estimated range, more than balancing the increased weight burden of nearly 10kg. By enabling the possibility to consider and test the real behavior of powertrain components, the HIL platform has proven to be an effective tool for design purposes.
Investigation of Plug-In Hybrid Light Duty Commercial Vehicle in Real-World Conditions by Simulation
Authors: Mancaruso Ezio , Meccariello Giovanni , Rossetti Salvatore
Published: September 2024

Light commercial vehicles are an indispensable element for the transport of people and the delivery of goods, especially on extra-urban and long-distance routes. With a view to sustainable mobility, it is necessary to think about hybridizing these vehicles to reduce the fuel consumption as well as greenhouse gas emissions and particulate matter. These types of vehicles are generally powered by diesel and travel many kilometers a day. On the other hand, the use of light commercial vehicles in battery electric vehicle (BEV) configuration has already been started but is not receiving widespread recognition. In this panorama, starting from a study already developed for the hybridization of a plug-in light commercial vehicle in Worldwide harmonized Light vehicles Test Cycle (WLTC) condition, the simulation analysis has been extended to the plug-in hybrid vehicle (PHEV) operating in real driving emission conditions (RDE). In particular, using Advisor software, a vehicle has been simulated in different plug-in hybrid configurations. The software has been validated with real operation data of a euro 6 diesel engine. The general hypothesis underlying the research consists in the possibility of using these vehicles in totally electric mode in the city and in hybrid mode outside urban centers; with the aim of reducing polluting emissions in populated city but completing the delivery mission during all phases of vehicle operation. The PHEV simulations have been performed on both WLTC and RDE condition. In the latter mode, particular attention has been devoted to the interpretation of data from GPS sensor: like the slope of the route or the presence of tunnels. The success of the simulation depends on a correct and careful reconstruction of the GPS data. Three vehicles with different hybridization factors have been simulated: 0.44, 0.56, and 0.67, respectively, with power equal to that of the base vehicle. The battery packs have been sized for the three hybrid vehicles and simulations were carried out in both Charge Depleting and Charge Sustaining configuration. In charge depleting for the highest hybrid configuration (HF=0.66), the results demonstrate that a reduction of up to 80% and 76% in fuel can be saved While a reduction up to 75% and 45% in NOx emissions can be achieved on WLTC and RDE cycle, respectively. On the other hand, when the battery is discharged, for HF=0.67, although consumption can be reduced by up to 45%, NOx emissions also increase by 183% even if ICE operation mode has to be better optimize for hybrid operation. Finally, even if the hybrid solutions is really convenient if compared to the conventional vehicle in terms of fuel savings and NOx pollutant emissions, about a realistic estimation of the CO2 reduction that can be achieved the use of electrical energy must be take into account.
Life Cycle Analysis of a PEM Fuel Cell System for Long-Haul Heavy-Duty Trucks
Authors: Gentilucci Gaia , Accardo Antonella , Spessa Ezio
Published: September 2024

The European Union plans to reach net-zero greenhouse gas (GHG) emissions in 2050. In 2020, the transport sector significantly contributed to global energy-related GHG emissions, with heavy-duty vehicles (HDVs) responsible for a substantial portion of road transport emissions in the EU and a notable percentage of the EU’s total GHG emissions. Zero-emission vehicles (ZEVs), including fuel cell (FC) vehicles, are crucial for decarbonizing the transport sector to achieve climate neutrality. This paper aims at quantifying the environmental impacts of a 200kW proton exchange membrane FC system for long-haul HDVs with a 40-ton mass and 750 km driving range. The life cycle assessment (LCA) methodology was applied, and a life cycle model of the FC system was developed with a cradle-to-grave boundary. To ensure reproducibility and scalability, results are reported on a kW basis. A sensitivity analysis was performed on key parameters, including hydrogen production route, FC system production location, fuel consumption, FC system size, FC system replacement, and FC material composition. At the cradle-to-gate boundary, GHG emissions of the FC system ranged from 30.5 to 51.4 kg CO₂eq/kW. The catalyst was the most impactful component due to the presence of platinum, followed by the balance of plant. In the cradle-to-grave boundary, raw material extraction and production phases were negligible, while the use phase was the main driver of the overall impact of the FC system. Certain equivalences were observed when considering other impact categories.
Enhancing Homogeneity and Combustion Efficiency in Gas Engines: A Novel Approach through Swirl-Inducing Air Intake Pipe Modifications
Authors: Gutierrez Marcos , Taco Diana
Published: September 2024

The lack of a homogeneous air-fuel mixture in internal combustion engines is a major cause of pollutant emissions, such as carbon monoxide (CO) and hydrocarbons (HC). This paper focuses on the design, simulation, and testing of a modified air intake pipe for a gas engine, incorporating deflectors to induce a swirl effect in the air-fuel mixture. To determine the optimal configuration for the deflectors and the diameter of the air intake pipe, several Computational Fluid Dynamics (CFD) simulations were conducted. The best results were then tested on a real gas engine. The primary objective of this study is to offer a solution for increasing the homogeneity level of the air-fuel mixture in gas engines, without requiring significant changes to engine components. In this case, achieving this goal involves only relatively small modifications to the air intake pipe. The results indicate that the swirl effect effectively enhances the homogeneity of the air-fuel mixture by generating higher turbulence along the air intake path. Critical to the success of the modification is the maintenance of the original pressure drop along the pipe. To compensate for the restriction caused by the deflector in the cross-sectional area of the air intake pipe, it is necessary to increase the diameter of the pipe. The most challenging aspect was achieving a reduction in CO and HC emissions due to the deflectors, rather than solely relying on the increased diameter of the air intake pipe. Importantly, the goal was to maintain engine power without a corresponding increase in fuel consumption. Contrary to the common belief that any device disrupting the free flow through the air intake pipe causes pressure losses, our findings suggest that the right configuration of pipe diameter, along with the appropriate number and positioning of deflectors, can yield better results than maintaining an unrestricted airflow. In summary, our work presents a device intended for implementation in the air intake pipe of gas engines, inducing a swirl in the air-fuel mixture without creating pressure losses compared to the original engine condition. This modification successfully reduces CO and HC levels, serving as an indicator of improved combustion resulting from a more homogeneous air-fuel mixture.

Authors: Zeng Jia , Zhao Yao , Gao Di , Lu Xiang , Dong Jing-Jing , Liu Yan-Bing , Shen Bin
Published: September 2024

BACKGROUND

Coronary artery diseases can cause myocardial ischemia and hypoxia, angina pectoris, myocardial infarction, arrhythmia, and even sudden death led to inflight incapacitation of aircrew. As the main cause of grounding due to illness, they severe threats to the health and fighting strength of military aircrew. Early warning in an early and accurate manner and early intervention of diseases possibly resulting in inflight incapacitation are key emphases of aeromedical support in clinic.

AIM

To figure out the flight factors and clinical characteristics of military aircrew with abnormal results of coronary artery computed tomographic angiography (CTA), thereby rendering theoretical references for clinical aeromedical support of military flying personnel.

METHODS

The clinical data of 15 flying personnel who received physical examinations in a military medical center from December 2020 to June 2023 and were diagnosed with coronary artery diseases by coronary artery CTA were collected and retrospectively analyzed, and a descriptive statistical analysis was conducted on their onset age, aircraft type and clinical data.

RESULTS

The 15 military flying personnel diagnosed with coronary artery diseases by coronary artery CTA were composed of 9 pilots, 1 navigator and 5 air combat service workers. Multi-vessel disease was detected in 9 flying personnel, among which 8 (88.9%) were pilots. Flying personnel with multi-vessel disease had higher content of cholesterol, low-density lipoprotein cholesterol and apolipoprotein B than those with single-vessel disease.

CONCLUSION

Coronary artery diseases are the major heart disease for the grounding of flying personnel due to illness, which can lead to inflight incapacitation. Coronary artery CTA is conducive to early detection and early intervention treatment of such diseases in clinic.
Intracoronary thrombolysis combined with drug balloon angioplasty in a young ST-segment elevation myocardial infarction patient: A case report
Authors: She Li-Qiong , Gao De-Kui , Hong Le , Tian Yin , Wang Hui-Zhen , Huang Sheng
Published: September 2024

BACKGROUND

The combination of acute ST-segment elevation myocardial infarction (STEMI) and gastric ulcers poses a challenge to primary percutaneous coronary intervention (PPCI), particularly for young patients. The role of drug-coated balloons (DCBs) in the treatment of de novo coronary artery lesions in large vessels remains unclear, especially for patients with STEMI. Our strategy is to implement drug balloon angioplasty following the intracoronary administration of low-dose prourokinase and adequate pre-expansion.

CASE SUMMARY

A 54-year-old male patient presented to the emergency department due to chest pain on June 24, 2019. Within the first 3 minutes of the initial assessment in the emergency room, the electrocardiogram (ECG) showed significant changes. There was atrial fibrillation with ST-segment elevation. Subsequently, atrial fibrillation terminated spontaneously and reverted to sinus rhythm. Soon after, the patient experienced syncope. The ECG revealed torsades de pointes ventricular tachycardia. A few seconds later, it returned to sinus rhythm. High-sensitivity tropon in I was normal. The diagnosis was acute STEMI. Emergency coronary angiography revealed subtotal occlusion with thrombus formation in the proximal segment of the left anterior descending artery. Considering the patient's age and history of peptic ulcer disease, after the intracoronary injection of prourokinase, percutaneous transluminal coronary angioplasty and cutting balloon angioplasty were conducted for thorough preconditioning, and paclitaxel drug-eluting balloon angioplasty was performed without any stents, achieving favorable outcomes.

CONCLUSION

A PPCI without stents may be a viable treatment strategy for select patients with STEMI, and further research is warranted.
Medical dilemma: Programmed death 1 blockade (sintilimab) therapy in patients suffering from tumours combined with psoriasis
Authors: Jin Di , Wang Yu-Wei , Lin Zhi-Min , Li Chen , Li Ming
Published: September 2024

Tumour immunotherapy represented by immune checkpoint inhibitors (ICIs) has greatly improved the overall prognosis of patients with malignant tumours, and is regarded as an important breakthrough in the field of medicine in recent years. ICIs have gradually become the core of tumour therapy and are increasingly used in the clinic. In order to achieve early clinical prediction and management of immune-related adverse events (irAEs), it is still necessary to perform further research on the mechanisms, risk factors, and predictors of irAE occurrence in the future. Zhou et al describe the consultation of a patient with advanced gastric cancer combined with chronic plaque psoriasis. This case provides an important reference for the use of programmed cell death protein-1 (PD-1) inhibitors in patients of tumours combined with chronic plaque psoriasis. This case also highlights that screening of high-risk groups for irAEs is critical before applying PD-1 inhibitors to patients with chronic psoriasis combined with tumours. PD-1 inhibitors are new and potent antineoplastic agents that can cause serious immune-related adverse events such as toxic epidermal necrolysis release and psoriasis. Glucocorticosteroids are the first-line agents for irAEs. The incidence of rheumatic irAEs may be higher in reality, which will inevitably become a new challenge for rheumatologists and dermatologists.

Effective coping and healing strategies are outlined from various vantage points. Overall, the article contributes to filling in the research gap by centering racialized personal narratives in the Canadian context, offering nuanced lessons for integrating research and activism, and showcasing tangible ways to support the needs of youth and families through community-oriented, trauma-informed approaches.
Institutional Logics of Indigenization in Canadian Higher Education: The Role of Critical Policy Analysis as a Research Tool to Activate Social Change
Authors: Gardiner Milln Danielle
Published: September 2024

A common approach to adopting large-scale social changes in organizations is to codify them within high-level policies, including strategic plans. One such social change with increasing attention is the move towards “Indigenization” throughout all organizations in Canada, with national and international policy imperatives supporting its robust enactment. To understand the overt and covert components of such policies to understand how such large-scale social changes might be codified and framed, critical policy analysis (CPA) is a useful methodological tool to support such policy implementation and inform further activism. To illustrate this, CPA is used in this study to highlight how Indigenous-centric strategic plans (ISPs) conceptualize Indigenization across the U15 institutions in Canada, the largest group of research-intensive institutions spanning the country with educational communities totalling hundreds of thousands of students, staff, faculty, and community connections. The representations of Indigenization in these ISPs are analyzed using Gaudry & Lorenz’s (2018) conceptual framework of Indigenization in higher education, finding that the ISPs largely represent an inclusionary approach to Indigenization, falling short of advancing reconciliatory or decolonial forms of Indigenization. Understanding that ISPs predominantly enable inclusionary Indigenization (Gaudry & Lorenz, 2018) illuminates the institutional logics that underpin Canadian higher education, namely that retaining power structures historically constructed through colonial processes are not overtly challenged by the actions outlined in the ISPs. Though directly acknowledging the need for Indigenization within higher education ISPs is a substantial advancement towards the social reality envisaged by the TRC (2015), this analysis spotlights where further activism is needed, including by educational leaders, to advance substantial reformation of colonial institutional logics within Canadian higher education.
Transforming the Canadian Policy Agenda for School-Based Prevention of Youth Homelessness: Research as Activism
Authors: Stroud Rebecca , Poulin Mélina , Sohn Jacqueline , Kennelly Jacqueline
Published: September 2024

Youth homelessness (YH) demands transformative changes in research, education, and public policy. Distinct from adult homelessness (AH), poorly addressed YH may lead to AH. Prevailing media narratives and policy communications perpetuate stigma and are unrepresentative of youth’s lived experiences, hindering the educational sector’s capacity to implement supportive measures in youth homelessness prevention. Schools are well poised to provide preventative and mitigative supports to address YH, yet the work intensification of educators has reached a point of fatigue, thus threatening support efficacy. We conceptualize research as activism and propose that policy can be engaged as a matter of social justice and a means to transform society via research and knowledge mobilization (KMb). Our Canadian environmental scan informs several studies in progress, which share goals to: prevent YH; reduce harms from intersectional issues to YH; and ameliorate conditions for resilience pertaining to youth in or at risk of homelessness. We call for a multi-pronged approach to engage stakeholders and the education sector in addressing this high-stakes issue disproportionately affecting underserved youth.

Inquiry for Social Transformation: Black Mother Scholars Redefining Scholarly Inquiry Through Black Artistic Expression
Authors: Fearon Stephanie
Published: September 2024

Writing, dancing, drawing, spittin’ rhymes, and other artistic expressions have long offered us, Black mother scholars, opportunities to reaffirm our humanity amid oppression (Fearon, 2023).  Art offers Black mother scholars space to reconceptualise inquiry in ways that engage our families, challenge injustices, and usher social change within the educational milieu and beyond. The centring of Black artistic expression in educational research invites Black mother scholars to affirm the parts of ourselves, our families, and our communities that dominant forms of inquiry and anti-Blackness have sought to discredit. Educational research grounded in Black artistic expression compels us all to reimagine scholarly inquiry for social transformation. In this paper, I critically reflect on an arts-informed research study I led with a group of Black Canadian mothers who are adult literacy learners. In this reflexive piece, I explore how grounding research practices in Black art allows opportunities for storytelling, story listening, and Black refusal. Specifically, this paper explores the ways Black art supports researchers in addressing power differentials inherent in inquiry processes. The paper concludes with a series of reflective questions challenging scholars, especially Black mother scholars, to redefine traditional academic boundaries and recommit to social transformation through the arts.

Authors:   , Solomon Cassidy
Published: September 2024

This capstone paper will discuss the development of an occupational therapy program to support the needs of youth within the foster system and prepare this population to live independently. Background information including statistics, the need for occupational therapy, and the program specifics such as rationale, significance, and objective are discussed. The development of an occupational therapy program to aid in the success of children within the foster care system helps close a gap in research that will contribute to this population's success and positive outcomes. The purpose of this capstone was to develop a program for children in the foster system, ages 15-18, to gain the life skills needed for independence in occupational participation of ADLs and IADLs. Foster children tend to have many contributing factors that lead to a decreased quality of life (AOTA, 2021). The training and education that occupational therapists can provide will allow these children to develop strategies and skills that will improve overall mental health status, functional life skill development, feelings of success, and an increase in quality of life.
