Participants report positive perceptions of these programs during and after completion, but evidence of concrete program outcomes is limited. Two potential outcomes of graduate student professional development are the use of pedagogical metacognition (reflection on and action upon teaching) and knowledge of teaching and learning (identification of research-based teaching strategies and application to …

Meeting Free Appropriate Public Education And Least Restrictive Environment Requirements For Students With Disabilities During The Coronavirus-19 Pandemic: Implications For Special Education Directors, Vanessa Lee Giddings

Dissertations

The Individuals with Disabilities Education Act (IDEA, 2004) addresses educational access in a brick-and-mortar setting but does not specifically address how to meet the parameters of free appropriate public education (FAPE) and least restrictive environment (LRE) in an online or virtual setting. An increased desire by students with disabilities and their parents to select online learning, coupled with the Coronavirus (COVID)-19 global pandemic, prompted many school districts to pivot to remote learning for an extended period and disrupted the traditional educational system (Molnar et al., 2021). This phenomenological research study elevated the lived experiences of special education directors during the …

Do Allyship And Motivation Influence Women’S Cognitive Functioning And Self-Regulation After Witnessing Sexism?, Christina Garasky

Dissertations

Prior research shows the effects of sexism can accumulate over time, resulting in severe negative, cognitive, affective, motivational, and physiological consequences for women; however, most research focuses on the consequences of being a direct target of sexism, and the cognitive and motivational consequences of being a witness of sexism have not yet been fully explored. Additionally, while it is thought that allyship can help mitigate the consequences of sexism, minimal research has tested this relationship. It was proposed that shifts in reactive approach motivation (RAM); aimed to protect against anxiety and negative affect, may direct attention away from goal-oriented behaviors, …

The Motherhood Crusade: Rural Low-Income Mothers, Support, And Empowerment, Christina Castellano

Loss Scaling And Step Size In Deep Learning Optimizatio, Nora Alosily

Dissertations

Deep learning training consumes ever-increasing time and resources, and that is
due to the complexity of the model, the number of updates taken to reach good
results, and both the amount and dimensionality of the data. In this dissertation,
we will focus on making the process of training more efficient by focusing on the
step size to reduce the number of computations for parameters in each update.
We achieved our objective in two new ways: we use loss scaling as a proxy for
the learning rate, and we use learnable layer-wise optimizers. Although our work
is perhaps not the first …

Perceptions Of And Approaches To Social Support Exchange While On Probation And Parole, Andrea Giuffre

Dissertations

The vast number of individuals on community supervision (i.e., probation and parole) remains at around 4.5 million Americans and suggests a need for research that delves deep into the nature of challenges faced by this population. Research demonstrates individuals on community supervision tend to rely on others for and provide social support to manage the challenges and conditions of community supervision. Simultaneously, many criminological theories incorporate elements of social support and speak to the importance of social relationships as predictors of criminal behavior, but less is known about the mechanisms underpinning social support exchange. Examination of the delivery and perceptions …

Topological Data Analysis Of Weight Spaces In Convolutional Neural Networks, Adam Wagenknecht

Dissertations

Convolutional Neural Networks (CNNs) have become one of the most commonly used tools for performing image classification. Unfortunately, as with most machine learning algorithms, CNNs suffer from a lack of interpretability. CNNs are trained by using a training data set and a loss function to tune a set of parameters known as the layer weights. This tuning process is based on the classical method of gradient descent, but it relies on a strong stochastic component, which makes the weight behavior during training difficult to understand. However, since CNNs are governed largely by the weights that make up each of the …

Anti-Woman Invective On The Early Modern Stage: Abuse, Degradation, And Resistance, Savannah Xaver

Dissertations

On the early modern stage, gendered epithets like “strumpet,” “mermaid,” “minx,” “hobby horse,” “courtesan,” “drab,” and “whore” are not just markers of misogyny. Instead, these insults harm the male user as well as their female target. My cross-playwright and cross-genre connections show the complex, wide use and impact of anti-woman terms. A wide-ranging study of the plays of Shakespeare and his contemporaries reveals that gendered insults signify masculine mental decline in tragedies as well as comedies and tragicomedies. In tragedy, the increasingly violent language of male slur users – like, for example, the frustrated Othello, who declares, of his wife, …
