The Power-Duration Relationship Is Just As Reproducible In Females As Males, Despite The Presence Of The Menstrual Cycle, Jessica Joy Linde
Theses and Dissertations
PURPOSE: To investigate the effect of the menstrual cycle (MC) on exercise performance across the power-duration relationship (PDR). We hypothesized females would exhibit greater variability in the PDR across the MC than males across a similar timespan, with critical power (PCRIT) and Work prime (W') being lower during the early follicular phase than the late follicular and mid-luteal phases. METHODS: Eumenorrheic, endurance-trained females (n = 10, age = 24.1 ± 5.59) performed multiple constant-load-to-task-failure and maximum-power tests at three time points across the MC (early follicular, late follicular, midluteal phases). Endurance-trained males (n = 10 age = 29.5 ± 9.18) …

Ambiguity Of Vision: Reimagining The Hypervisible Void, Kiwha Lee Blocman
Ambiguity Of Vision: Reimagining The Hypervisible Void, Kiwha Lee Blocman
Theses and Dissertations
Asking questions about what Painting is in the 21st century and the dominant narratives it can challenge, my paintings complicate the viewer’s reading of pictorial hierarchy and the projection of human relations in the world. I de-hierarchize and decentralize the compositional components that make up a painting by using patterns to create spatial depth, not European perspectival conventions. In dialogue with modernists such as Matisse who drew from the visual vocabulary of “The Orient”, my central forms derived from architecture and ornamental fragments possess a body-like presence. Further, I reinvent ancient Asian printmaking processes with oil paint. Observing the tenets …

In this thesis, this same focus is applied with respect to the field of machine learning for embedded devices which is still in the early stages of development. This focus is further used to develop various algorithms such as utilizing prior trained starting networks, weighted output schemes, and replay or reduced datasets for training while maintaining a consistent focus on low resource devices to maintain acceptable performance. The experimental results show an improvement in model training times as compared to …
Between The Garden And The Gardener, Sara Lynne Lindsay
Between The Garden And The Gardener, Sara Lynne Lindsay
Theses and Dissertations
My work uses plant material and soil as a record of personal, cultural, and ecological history. History is not only held in the buildings and monuments, but in the soil itself. I gather this soil and foliage from both cultivated and uncultivated locations for my artwork. Using traditional domestic techniques of drying and canning, I preserve the materials that I have gathered. These will then be sewn together, cooked, and encrusted into objects. Despite my labor of preserving, these organic art supplies are transient. When made into works of art, they can be viewed in their vulnerable state, fighting against …

Femqorg Index, Nahee Kim
Femqorg Index, Nahee Kim
Theses and Dissertations
The project Femqorg Index began as I realized an endless number of chatbots and robots were released into this world as a spark of technology wrapped in a feminine persona, only to be disposed of after a short period. My imagination then extended to the thought that after they were disposed of, the entities along with their memories and advanced technology, would converge to create a network of their own. In this network, needs of the chatbots and robots were met through the exchange of strengths such as an advanced problem-solving ability, or a sturdy body that allowed unrestricted movement. …

Graph-Based Unsupervised Entity Resolution For Identifying Entity Profiles In Ambiguous Data, Islam Akef Ebeid
Graph-Based Unsupervised Entity Resolution For Identifying Entity Profiles In Ambiguous Data, Islam Akef Ebeid
Theses and Dissertations
Entity resolution means finding duplicate records within the same table, across various tables, or in multiple databases. Traditional and rule-based approaches in entity resolution rely on handcrafting rules for matching records. On the other hand, machine learning and deep learning methods are data-intensive and require labeled training datasets. Thus the move toward automating entity resolution for data cleaning, curation, and integration has become the goal for many organizations. Accordingly, unsupervised entity resolution methods have proliferated, relying on an automated pipeline of preprocessing, blocking, feature extraction, matching, clustering, profiling, and canonicalization. Unsupervised entity resolution methods face many challenges due to the …

Wavelet Methods For Solving Fractional-Order Dynamical Systems, Kobra Rabiei
Wavelet Methods For Solving Fractional-Order Dynamical Systems, Kobra Rabiei
Theses and Dissertations
In this dissertation we focus on fractional-order dynamical systems and classify these problems as optimal control of system described by fractional derivative, fractional-order nonlinear differential equations, optimal control of systems described by variable-order differential equations and delay fractional optimal control problems. These problems are solved by using the spectral method and reducing the problem to a system of algebraic equations. In fact for the optimal control problems described by fractional and variable-order equations, the variables are approximated by chosen wavelets with unknown coefficients in the constraint equations, performance index and conditions. Thus, a fractional optimal control problem is converted to …

Do Opposites Attract…Or Aggravate? The Impact Of Intergenerational Solidarity On Well-Being, Rachel K. Scott
Do Opposites Attract…Or Aggravate? The Impact Of Intergenerational Solidarity On Well-Being, Rachel K. Scott
Theses and Dissertations
Family Systems Theory provides a framework for examining how values are transmitted between family members, and the overall impact transmission has on familial well-being. While familial emotional closeness has been linked to older-adult well-being, there is still a lack of research investigating the influence of ideological agreement between family members. This study examined grandparent-child and grandparent-grandchild dyads to assess the extent to which level of agreement on religious and political ideological beliefs moderates the relation between perceived intergenerational emotional closeness and well-being in grandparents. Affectual solidarity ratings among the generations, as well as religious ideological differences between grandparents and grandchildren, …

Evaluating Soil Health Changes Following Cover Crop And No-Till Integration Into A Soybean (Glycine Max) Cropping System In The Mississippi Alluvial Valley, Alexandra Gwin Firth
Evaluating Soil Health Changes Following Cover Crop And No-Till Integration Into A Soybean (Glycine Max) Cropping System In The Mississippi Alluvial Valley, Alexandra Gwin Firth
Theses and Dissertations
The transition of natural landscapes to intensive agricultural uses has resulted in severe loss of soil organic carbon (SOC), increased CO₂ emissions, river depletion, and groundwater overdraft. Despite negative documented effects of agricultural land use (i.e., soil erosion, nutrient runoff) on critical natural resources (i.e., water, soil), food production must increase to meet the demands of a rising human population. Given the environmental and agricultural productivity concerns of intensely managed soils, it is critical to implement conservation practices that mitigate the negative effects of crop production and enhance environmental integrity. In the Mississippi Alluvial Valley (MAV) region of Mississippi, USA, …

Borderline Personality Disorder And Suicide Risk: The Role Of Emotional Vulnerability, Parental Invalidation, And Adverse Childhood Experiences, Chandler Jayne Mcdaniel
Borderline Personality Disorder And Suicide Risk: The Role Of Emotional Vulnerability, Parental Invalidation, And Adverse Childhood Experiences, Chandler Jayne Mcdaniel
Theses and Dissertations
Childhood adversity is linked with a variety of negative outcomes including suicide attempts and personality disorders, most commonly Borderline Personality Disorder (BPD). A core feature of BPD, emotion dysregulation is often reported following early childhood adversity and contributes to both suicidal ideation and attempts. One explanation for the development of emotion dysregulation within BPD, is the biosocial model, which states that there must be an interaction between childhood emotional vulnerability and parental invalidation. Recent literature suggests that this interaction may not be necessary. Thus, the current study extended previous literature by examining childhood risk factors (i.e., ACES, parental invalidation, and …
