Involvement in Education for Families with ADHD: A Difference in Parent-Child Dynamics
Full text linkParental involvement in education is known to benefit students academically. It is less clear how beneficial parent involvement is for students with attention-deficit/ hyperactivity disorder (ADHD), especially considering how it may impact the parent-child relationship. The present study investigated the relationship between parent involvement variables (self-efficacy, role construction, time/energy, knowledge/skills, frequency of home- and school-based involvement), parent and child ADHD, and parent-child relationship quality. Data from 213 parents of children with diagnosed ADHD (Mage = 8.8) were analyzed. Results found that only parental self-efficacy was associated with stronger parent-child relationship quality. Parental ADHD had a significant effect on relationship-quality – parents without the disorder reported worsened parent-child relationships as inattentive child ADHD symptoms increased. There were no significant effects of child ADHD on relationship quality when parents had ADHD. The implications of parent involvement in education for this unique population is discussed. Keywords: Parental involvement, educational involvement, ADHD, parent-child relationshi
Systematic estimates and predictions of detection probabilities of North American landbirds, with applications for the North American Breeding Bird Survey
Full text linkIn biological surveys, detectability refers to the observer's ability to detect an organism, and is typically expressed as a probability. Often, detectability is ignored in conservation problems that draw from biological surveys, because the survey lacks ancillary information to estimate detectability, or detectability is simply unknown for a particular species. This can be problematic in instances where conservation managers may want to trade off monitoring versus action for a particular species, because it is impossible to know if zeros in a biological survey are true zeros because the species was not present, or a false zero because the species was there but not detected. North American birds have been studied and surveyed extensively; as such, there is a plethora of point count data that are available across several programs. Because of this, we are in an excellent position to estimate detectability of many landbird species using data-driven approaches, such that these detectability estimates may be used for future conservation purposes. In this thesis, I focus on this data-driven estimation of detection probabilities for over 300 species of North American landbirds. In Chapter 2, I provide an overview of how the detection process works in birds, and how to model detectability. In Chapter 3, I then provide a pipeline for data-driven detectability estimates, by using methodology developed by the Boreal Avian Modelling project. This allowed for detection probabilities to be estimated for 338 species of landbirds. I expand upon these species in Chapter 4 by demonstrating how the use of Bayesian hierarchical modelling can help ``fill in the gaps" for detection probabilities for data-sparse species. In Chapter 5, I apply these detection probabilities to the North American Breeding Bird Survey, a long-running bird survey that has not previously been able to account for detectability in their trend analysis. I show that by accounting for changes in detectability due to changes in the landscape at the local scale, trends can change dramatically from near-flat to highly decreasing. Finally, in Chapter 6, I examine the implications for conservation that the availability of detectability estimates can have, which include implications for data integration
Resilient or Violent? Educators' Perceptions of Refugee Children in Canadian Schools
Full text linkThis thesis explores how educators and school staff in Ottawa perceive refugee children through contrasting narratives of resilience and violence. Refugee children arrive in Canada with trauma from war, displacement, and loss, yet their experiences are often framed through racialized and rigid perceptions. Drawing on qualitative interviews with teachers, multicultural liaison officers, social workers, and reception center staff, this research reveals how these perceptions shape academic and behavioural outcomes. While resilience is frequently celebrated, it often ignores the systemic barriers refugee children face, placing the burden of success solely on them. At the same time, behaviours that diverge from dominant norms are frequently viewed as violent, reinforcing harmful racial stereotypes and affecting disciplinary actions. These binary narratives obscure the structural challenges within the education system. This study advocates for trauma-informed, culturally responsive training for educators and contributes to broader conversations about race, trauma, and educational equity in Canadian schools
Expert Experiences Designing, Developing and Evaluating Data Visualizations on Large Displays
Full text linkLarge displays can provide the necessary space and resolution for comprehensive explorations of data visualizations. However, designing and developing visualizations for such displays pose distinct challenges. Identifying these challenges is essential for data visualization designers and developers creating data visualizations on large displays. In this thesis, we aim to identify the challenges designers and developers encounter when creating data visualizations for large displays. We conducted semi-structured interviews with 13 experts experienced in creating data visualizations for large displays and, through affinity diagramming, categorized the challenges. We identified several challenges in designing, developing, and evaluating data visualizations on large displays, as well as building infrastructure for large displays
