Back Country: Queer Rural Temporalities, Pansies In The Bluegrass, Cooper Lane Gibson Feb 2023

Back Country: Queer Rural Temporalities, Pansies In The Bluegrass, Cooper Lane Gibson

Theses and Dissertations

My practice utilizes an intermedia and anti-disciplinary approach to conjure a reflexive vision of my experience as a gay and gender non-conforming person in rural Kentucky. Concepts that are important to my practice are storytelling, embodiment, and assemblage. Coming up gay in rural Kentucky I often felt like an assemblage. Not quite one thing entirely, but many parts swirling together in a fluidity that isn’t easily categorizable. Part farm boy, part faggot, part miss piggy. I am also interested in assemblage as a way of making. Found objects and images are tools I employ as a way of inviting the …

Deeptype: A Deep Neural Network Approach To Keyboard-Free Typing, Joshua V. Broekhuijsen Feb 2023

Deeptype: A Deep Neural Network Approach To Keyboard-Free Typing, Joshua V. Broekhuijsen

Theses and Dissertations

Textual data entry is an increasingly-important part of Human-Computer Interaction (HCI), but there is room for improvement in this domain. First, the keyboard -- a foundational text-entry device -- presents ergonomic challenges in terms of comfort and accuracy for even well-trained typists. Second, touch-screen smartphones -- some of the most ubiquitous mobile devices -- lack the physical space required to implement a full-size physical keyboard, and settle for a reduced input that can be slow and inaccurate. This thesis proposes and examines "DeepType" to begin addressing both of these problems in the form of a fully-virtual keyboard, realized through a …

The Crafting Of Pre-Service Special Education Teachers’ Perceptions Of Problem Behavior: A Post-Intentional Phenomenological Study, Jamillah Gilbert Feb 2023

The Crafting Of Pre-Service Special Education Teachers’ Perceptions Of Problem Behavior: A Post-Intentional Phenomenological Study, Jamillah Gilbert

Theses and Dissertations

A disproportionate number of Black students with disabilities experience exclusionary discipline practices (e.g., suspensions and expulsions) in K-12 public schools. This disparity persists, regardless of the severity of identified problem behavior, the school’s average socio-economic status, or the type of public school attended. Given that teacher education programs (TEPs) are pivotal training grounds for pedagogical and philosophical formation, it is crucial for TEPs to demonstrate accountability for building critical consciousness of the factors that produce and perpetuate this disparity. Gaining a fuller understanding of how pre-service special education teachers craft their perceptions of problem behavior during their TEPs may help …

Otherhood: Tracing Childhood In Korean American Literature For Youth, Nina Hanee Jang Feb 2023

Otherhood: Tracing Childhood In Korean American Literature For Youth, Nina Hanee Jang

Theses and Dissertations

In this dissertation, I explore the ways in which childhood is represented in three Korean American narratives for youths: An Na’s the Fold, Lyla Lee I’ll Be the One, and Tae Keller’s When You Trap a Tiger to theorize the concept of Otherhood, that is, a childhood in which the experience of being Othered is fundamental to a young person’s evolving identity formation and sense of power. I analyze how one’s identity makes a profound impact on their process of growth while their ontological awareness, sense of community, and heritage contribute to their empowerment as an Other.

Investigating The Molecular Mechanisms Of Spore Killing By Neurospora’S Meiotic Drive Elements, Nicholas Rhoades Feb 2023

Investigating The Molecular Mechanisms Of Spore Killing By Neurospora’S Meiotic Drive Elements, Nicholas Rhoades

Theses and Dissertations

Meiosis is a fundamental and highly conserved biological program that is required for sexual reproduction in eukaryotes. During meiosis, duplicated chromosomes synapse with their homologous partner and undergo a physical exchange of genetic material through recombination. The meiotic products resulting from this program contain novel combinations of alleles that are inherited by individuals in the succeeding generation. The random assortment of alleles during meiotic recombination allows for the chance that any such allelic combination may provide an increase (or decrease) in fitness for an individual. Alleles, or combinations of alleles, that are beneficial to the organism may be retained within …

On Income Inequality And Poverty In Egypt: Is Prosperity Immoral?, Mohamed Karim Lotfy Abdelkhalek Feb 2023

On Income Inequality And Poverty In Egypt: Is Prosperity Immoral?, Mohamed Karim Lotfy Abdelkhalek

Theses and Dissertations

There are varying perspectives on, and divergent solutions to, the phenomena of income inequality and poverty. There seems to be polarizing views on both of these sensitive topics. One side of the argument believes income inequality should in itself be mitigated through redistribution measures, while the other argues that this should not be the focus of policy makers, as it deters them from facing the more pressing issue facing society – which is absolute poverty. The relationship between income inequality, poverty, and citizen well-being in Egypt is one that warrants further research, and this paper aims to fill this lacuna. …
