    Embracing neurodiversity in education: promoting the inclusion of autistic students in education through podcasts

    Get PDF
    The purpose of this portfolio is to share how students with an autism diagnosis can benefit when their teachers, principals, guidance counselors, and peers learn about neurodiversity. In my project, I asked the following questions to explore ways educators can create an inclusive school community for Autistic students. 1. What are the experiences of Autistic youth in secondary schools? (Exploring behavior, anxiety, sensory differences, gender, and special interests). 2. How does promoting the neurodiversity mindset among students and educators promote the inclusion of Autistic students in secondary schools? I also sought to explore strategies that support inclusion in the classroom and school community. The findings provide insight into the strategies and approaches that educators and parents can use to foster social development, inclusion, and acceptance of students with an autism diagnosis. In my literature review, I noted many Autistic authors and share their insights as well as ideas for incorporating strategies for inclusion and also explored how the neurodiversity perspective benefits all students (Armstrong, 2012; Garcia, 2021; Honeybourne, 2018; Kapp et al., 2019; Loud Hands, 2012; Majoko & Majoko, 2016; Nerengerg, 2020; Price, 2022; Silberman, 2015; Walker, 2021). The objective of this portfolio was to develop a space where I could share and amplify Autistic people’s work, share strategies to better support Autistic people for inclusion, and explore the concept of neurodiversity in education in the form of podcasts. I also had the idea that these podcasts could potentially carry on after this portfolio work. In the end, I hope to share my work with colleagues, friends, and family to encourage inclusion of Autistic people in terms of what Autistic people are saying about inclusion

    Student perspectives on preparation to be just and socially responsible providers: a Northwestern Ontario qualitative case study

    Get PDF
    There is increasing recognition of the need to create just and socially responsible healthcare providers (HCP). Such recognition is evidenced by health professions training programs’ accreditation standards and expected competencies, as well as calls to action from the World Health Organization (WHO) (WHO, 2021, p. 25; WHO, 2022, p. 21), United Nations Sustainable Development Goals (2015) and, specifically in Canada, the calls to action from the Truth and Reconciliation Commission of Canada (including: 23iii, and 24 which deal with health professions education, and 44 relating to the actualizing of the United Nations Declaration on the Rights of Indigenous Peoples). Such calls to action are the result of health gaps between populations and instances of racism reported throughout the healthcare system. For example, in recent years discrimination and racism within the healthcare system has resulted in very evident consequences such as the premature death of Joyce Echaquan in 2020 (Nerestant, 2021). This study looked at the effectiveness of post-secondary curriculum and initiatives in preparing health professions students to work in a safe and equitable manner with diverse populations in response to these calls to action.

    Matching mobile crisis models to communities: an example from Northwestern Ontario

    Get PDF
    Due to the potential safety risks and nature of crisis response systems in Canada, police are often the first to encounter individuals when they are experiencing a mental health crisis. However, other professionals with different skill sets may be needed to optimize crisis response. As such, police and mental health service agencies have partnered to create mobile crisis response teams (MCRTs) consisting of police and mental health professionals who partner in crisis call response. While past evaluations of MCRTs have shown promising results (e.g., hospital diversions; costeffectiveness), these programs are frequently researched in larger urban contexts. How MCRTs function in smaller jurisdictions, with fewer complementary resources, is unknown. Using an extended Donabedian model as a guiding framework, I conducted interviews with frontline and leadership staff, ride-along site visits, and reviewed program and agency documents to illustrate how the MCRT model operates in the context of the mid-size, geographically isolated, city of Thunder Bay, Ontario.

    A spatial analysis of the relationship between forest demographic dynamics and diversity under climate change

    Get PDF
    Forest dynamics arise from three demographic processes simultaneously, namely recruitment, mortality and growth, all of which are expected to accelerate for the boreal forest under future climate change. Tree species diversity, however, is hypothesized to mitigate the impacts of climate change on the rates of these demographic processes. At the same time, understanding the generation and maintenance of tree species diversity is a historical challenge and requires examining multiple demographic dynamics simultaneously. The purpose of this dissertation is to investigate the complex relationship between tree demographics and diversity under the influence of climate change through spatial analysis of 173 permanent sample plots in the boreal forest of Manitoba, Canada, at the individual-tree level. A mapped dataset of individual stems that were repeatedly measured from 1986 to 2010 forms the basis of three studies. [...

    A high throughput screening and characterization of laccase-producing bacterium Serratia quinivorans AORB19 that exhibits lignin degradation traits, dye decolorization efficiency, and enhanced laccase production in biomass

    Get PDF
    Laccase (EC 1.10.3.2) assumes a vital role in the degradation of lignin by utilizing oxygen as an oxidant and catalyzing bond cleavage in both phenolic and nonphenolic lignin model compounds. However, their industrial application is limited due to reduced enzymatic activity and lower tolerance to extreme conditions in most laccases isolated from microorganisms. To address these challenges, bioprospecting for strains harboring novel laccases with enhanced activity and versatile properties is paramount. Natural biodegradation processes offer promises for lignin degradation, and rapid screening methods aid in isolating microorganisms secreting extracellular lignin-degrading enzymes, including laccases. In our study, we developed a novel high-throughput screening process to isolate a promising lignin-degrading bacterium from decomposed wood samples. Whole-genome analysis and LC-UV (Liquid Chromatography-Ultraviolet Detection) analysis was employed to identify the species and assess its lignin-degrading traits. This bacterium exhibited significant extracellular laccase production and was biochemically characterized. Moreover, the potential of this bacterium in bioremediation, specifically in the decolorization of two major dyes, was probed. Additionally, the laccase secretion capabilities of the bacterial strain were assessed by utilizing low-cost industrial wastes from the Canadian agro-industries. [...

    Experimental investigation of exposed column base plate connections subjected to combined axial and bi-directional lateral loading

    Get PDF
    Column base plate (CBP) connections are critical components in the overall design of a steel structure. CBP connections are responsible for transferring the forces exerted on base columns through a base plate and grout pad into the concrete foundation utilizing anchor rods. Exposedtype column bases are widely used in low-rise building construction all over the world, and considerable research efforts have been made to identify the parameters that affect their strength and serviceability. Current design codes and guidelines do not address the design of these exposed base plate connections under combined axial load and bi-axial bending. Although, the columns are designed and checked under combined axial load and bi-axial bending, when it comes to the base plate connection, only the axial load and major axis bending are considered. Practicing engineers often adopt complex finite element method or design them in two directions separately, which often results in overly conservative design. A more direct approach to designing CBP connections subjected to combined axial and lateral loading conditions would help ensure column base connections perform as intended under extreme loading. The inadequate design of a CBP connection will cause the failure of the connection before the column can reach its peak design values. This configuration is known as a "Strong Column / Weak Connection". This failure is initiated by the inelastic deformation of one or more of the following components: anchor rods, concrete, grout, weld, or base plate. The design of all these components will have a combined effect on the CBP connection's stiffness, strength, and deformation capacity. [...

    Dynamic stability of an axially loaded elastically restrained column

    No full text
    The dynamic stability of axially loaded columns is a key problem in structural analysis, and in earthquake engineering particularly. Experience has shown that columns occasionally buckle when subject to dynamic axial loads that are only a small fraction of the load-carrying capacity predicted by static methods. While the mechanism behind these failures has been identified, theoretical studies have focused almost exclusively on pin-pin (and, to a lesser extent, fixed-fixed) connections. In practice, however, most columns have fixities between these two extremes and are described as having semi-rigid or elastically restrained supports. Very few studies have been conducted on this condition, and of the studies performed, none have included experimental verification. Additionally, calculation of the stability based on existing methods is very computationally expensive, as they calculate the response of the column, rather than the stability behavior. As a result, dynamic stability theory is not yet directly applicable to most design situations. To apply this theory to key problems in earthquake and structural engineering, a more practical approach to computing the stability behavior of more complex support conditions is required. This research studies the dynamic stability of axially loaded columns with elastically restrained supports theoretically, numerically, and experimentally. The equation of motion of an elastically restrained column is first derived and converted to a Mathieu equation, from which the stability regions can be obtained using Bolotin’s method. Second, a numerical method is developed to compute the state transition matrix for a particular excitation, giving the stability condition and response simultaneously. This numerical method is compared to the analytical results to determine the relative error associated with both the analytical and numerical solutions. Third, a novel experimental apparatus capable of simulating an axially loaded column with elastically restrained supports is designed in the laboratory. The experimental apparatus is capable of providing experimental verification for the matrix-based numerical method and is fully automated to allow the collection of large quantities of data. Due to unforeseen equipment damage, the experimental data could not be collected, but the automation was sufficiently advanced at the time of damage to be proven in principle

    Are youth differentially impacted by cannabis advertising? An ecological momentary assessment of demographic and psychosis risk factors in a Canadian post-legalization context

    Get PDF
    The Canadian government’s efforts to prevent cannabis use among youth are warranted, as early cannabis use greatly increases risk of harm. Although it is illegal, cannabis companies continue to advertise their products to youth, potentially influencing cannabis expectancies and use intentions. Some youth groups may be more susceptible to advertising based on demographic risk factors (urbanicity, gender, ethnicity, age) and psychosis risk. Ecological Momentary Assessment (EMA) enables youth to track a range of phenomena, in vivo. Using EMA, this research describes: How cannabis advertising is reaching youth, how such exposures may impact cannabis expectancies and use intentions, and whether at risk (demographics, psychosis risk) youth groups are differentially impacted by cannabis advertising exposures. Over a nine-day EMA protocol, 120 youth aged 14-18 completed demographic and psychosis-risk questionnaires, captured cannabis advertising exposures, and rated their reactions (expectancies and use intentions) to exposure(s) and during two daily randomly issued (control) prompts. Altogether, most (n = 85; 70.83%; range 1-30) youth reported being exposed to cannabis advertisements through various channels. Using multilevel models, this study also found that advertisement exposure increased cannabis use intentions, while it did not increase cannabis expectancies. Interaction effects for all demographic predictors and psychosis risk on expectancies and use intentions were also nonsignificant. [...

    A new control technology for the development of an air-to-air refueling system

    Get PDF
    Air to Air Refueling (AAR) was first performed over 100 years ago and until now it has almost exclusively been used in military applications. This is due to the prohibitive cost of maintaining a tanker fleet to enable refueling operations as well as the amount of training required by both tanker and receiver pilots to mitigate the risk involved with operating aircraft in close proximity. There are two methods of performing AAR operations: probe-drogue and flying boom. This work investigates the feasibility of converting a civilian tanker into a probe-drogue tanker for use in civilian applications. The aircraft chosen for this work is FuelBoss AT-802 as a fuel hauler. The first objective of this thesis is to model the AT-802 and explore its potential role as an AAR tanker. The second objective of this thesis is to address the issue of risk in AAR by modeling a hose-drogue and proposing a new control technology to stabilize a drogue in flight. As no drogue system is available for experimental testing, a flexible smart structure lab workstation will be used to investigate control strategies for vibration suppression under variable system dynamics. A Deep Deterministic Policy Gradient (DDPG) algorithm is proposed in conjuncture with Domain Randomization for reinforcement training of the controller. The effectiveness of the proposed control technique and learning algorithm is verified by experimental tests, with comparison to other related control methods such as the built-in PD controller and an intelligent NF controller. Dynamic conditions of the flexible structure are simulated by placing magnetic mass blocks at different positions on the beam. Experimental results show that the proposed DDPG controller outperforms other related control methods in terms of settling time, overshoot, and mean error, without sacrificing robustness and stability. It can learn a decision-making policy in environments with large action spaces such as in vibration suppression and has potential to used for hose-drogue system control
