Unraveling The Relationship Between Sexual Shame And Father-Child Sex Communication, Hannah Mireya Brundage

Theses and Dissertations

This study sought to understand the relationship between father’s sexual shame and children’s sexual shame. Parents play a role in shaping their children’s behaviors and perceptions in regard to sexuality. Most of this research analyzed data from the viewpoint of the mother, missing the potentially unique perspective and influence of fathers. Using longitudinal survey data from 361 fathers-adolescent dyads, I proposed to study the relations between father sexual shame and child sexual shame, and the possible mediating role of father-child sex communication. I predicted that quality of sex communication, including controlling and open communication, would mediate father sexual shame and …

Enhancing Fault Tolerance In Tmr Soft Risc-V Fpga Socs Through Failure-Driven Mitigation Strategies, Andrew Elbert Wilson

Theses and Dissertations

Field-Programmable Gate Arrays (FPGAs) leveraging soft processors, particularly those implementing the open-standard RISC-V Instruction Set Architecture (ISA), are increasingly important for space missions due to their adaptability and reconfigurability. However, their susceptibility to radiation-induced Single Event Upsets (SEUs) presents significant reliability challenges, necessitating robust fault-tolerant strategies such as Triple Modular Redundancy (TMR). This dissertation evaluates the effectiveness of TMR-based mitigation techniques for Linux-capable soft RISC-V System-on-Chip (SoC) implementations deployed on SRAM-based FPGAs operating in high-radiation environments. Using a combination of deterministic fault injection and neutron radiation testing, this work identifies critical residual single-point failure modes that persist in TMR-protected designs. …

Applying Ceragenins In Translational Medicine: Activating Mesenchymal Stem Cells And Preventing Healthcare-Associated Infections, Aaron L. Zaugg

Theses and Dissertations

Healthcare-associated infections are a major global concern. Increased infections among vulnerable populations lead to millions of deaths, annually, complicated by the emergence of multi-drug resistant pathogens. These infections are often facilitated by medical devices serving as abiotic surfaces that facilitate the formation of biofilms. Notably, colonization of prostheses and other bone-associated medical devices can lead to corrective procedures, revisions and death. To address these issues, inspiration can be drawn from natural sources of bone health and defenses against infection. Cathelicidins are endogenous peptides involved in both bone maintenance and infection control. Ceragenins are small molecule mimics of cathelicidins with broad …

Linking Static And Dynamic Structures And Properties Of Materials With Computational And Mathematical Models, (Enoch) Sin Hang Ho

Theses and Dissertations

Terahertz (THz) spectroscopy is an effective technique to study and manipulate the structural dynamics of materials, due to its frequency range being very similar to the vibrational frequencies of collective atom motions in a host of materials. High-field and broadband THz radiation can be generated via optical rectification (OR) in nonlinear optical (NLO) crystals. The efficiency of OR response in an NLO crystal is determined by many factors, including molecular hyperpolarizability (β), 2nd order electric susceptibility (χ(2)), crystal structure, primary growth orientation, refractive index, absorption and phase matching condition. In this dissertation, I will focus on using computation methods and …

Predicting Single-Leg Eccentric Hamstrings Strength In Aging Athletes Using Diagnostic Ultrasound- And Survey-Derived Parameters, Lee J. Hinkle

Theses and Dissertations

Introduction: Eccentric hamstring strength declines with age and contributes to mobility limitations. Although Nordbord testing quantifies eccentric strength, few studies have examined it in older adults, and none have predicted strength performance on this test using ultrasound or survey- based measures. Methods: We recruited 122 senior athletes (60 female) at the 2024 Huntsman World Senior Games. Ultrasound-derived cross-sectional area (CSA), echogenicity, and subcutaneous fat thickness, along with demographic and activity data, were used to predict single-leg peak force using Bayesian regression. Models were sex-stratified, and predictors were selected using leave-one-out cross-validation (LOO IC). Results: In males, CSA, age, leg side, …

The Exaggerated Blood Pressure Response To Activities Of Daily Living And Exercise Is Dependent Upon The Fitness Of People With Hypertension, Joseph D. Larsen

Theses and Dissertations

Purpose: Determine if the previously reported exaggerated systolic blood pressure response to daily activity and moderate exercise amongst hypertensive adults could be accounted for by differences in fitness. Methods: 30 normotensives adults (15 low fitness control (LFC) and 15 high fitness control (HFC)) and 15 unmedicated adults with ambulatory hypertension (HTN) participated in this study. Participants completed 24-hour ambulatory blood pressure monitoring (ABPM). Lactate Threshold (LT) and estimated ����̇O2max were determined for each participant. A week later, blood pressure was measured while participants completed 5-minute bouts of treadmill exercise at fixed absolute intensities (2.5 mph 0% and 12% grade) and …

Characterization Of Ultra-High-Speed Friction Stir Welds Made In Thin Sheet Aa6061-T4 Material, Todd Grant Lainhart

Theses and Dissertations

Friction stir lap welding (FSLW) of thin aluminum sheets in industry and in research has faced challenges in weld quality that limit welding speeds. Interfacial defects such as hooking and thinning are common defects that appear at the interface of FSLW, and researchers and process operators have traditionally reduced process parameters such as feed rate and spindle rotation to fully eliminate the defects. While such measures are successful in creating fully consolidated FSLW, feed rates for FSLW have stagnated around 1 mpm with the fastest feed rates recorded at 3 mpm, making it difficult for manufacturers to implement FSLW in …

Computational Advances For Single-Cell Proteomics, Hannah Boekweg

Theses and Dissertations

The overarching goal of biologists is to characterize biological systems. When the workings of a system are understood, they can be fixed, broken, preserved, mimicked, and even replicated. The field of proteomics seeks to characterize systems through the lens of proteins. Proteins are referred to as the 'workhorse' of the cell to illustrate that they perform most functional tasks within the cell. These tasks are highly varied, including enzymatic activity, structural support, transport, storage, cell signaling, gene regulation, immune response, and more. Proteomics has been instrumental in new biological discoveries by characterizing the functional state of cells. A new area …

“Perfect Hearts And Pure Pages”: The Transmission And Recitation Of The Qur’An In Mamluk Cairo—The Shāṭibiyya As A Case Study, Jonathan Hearn

Theses and Dissertations

The Ḥirz al-Amānī wa-Wajh al-Tahānī of Abū al-Qāsim b. Fīrruh al-Shāṭibī (d. 590/1193) became one of the most widely studied texts associated with the recitation of the Qur’an. A didactic versification of Abū ʿAmr al-Dānī’s (d. 444/1053) Kitāb al-Taysīr fī al-Qirāʾāt al-Sabaʿ, the Shāṭibiyya was composed in Ayyubid Egypt and transformed the discipline of the variant readings (qirāʾāt). Despite its popularity and acknowledged impact upon the discipline, the Shāṭibiyya remains a relatively untapped resource for understanding the Qur’an in its recited form. This thesis studies the recitation of the Qur’an in Mamluk Cairo through the Shāṭibiyya, …

In-Service Teachers’ Awareness And Professional Development In Egyptian Public Schools, Hanan Mohamed Metawea

Theses and Dissertations

Neuroscience is an emergent field that focuses on studying brain structure and understanding its significance in the learning process. There has been a recent movement in how to bridge the gap between neuroscience concepts and education by incorporating neuroscience principles into the teaching process. However, there have been limited studies in Egypt on how educators understand and utilize neuroscience principles in the classroom. This qualitative exploratory case study examines Egyptian teachers’ understanding of neuroscience concepts and how they apply them in their teaching practices. This case study was carried out in two government schools, including interviews with 11 teachers representing …

Paradise Lost Thrice: Exile And The Abrahamic Religions In Aciman, Werfel, And Ashour, Malak K. Hosny

Theses and Dissertations

Exile is an integral part of the history of all three Abrahamic religions: Judaism, Christianity and Islam. This thesis compares between literary narratives of the exile of Jews, Christians, and Muslims. It explores the notion that having been exiled from Eden with the fall of Adam and Eve, and having each religion’s prophet’s story intrinsically tied with exile, the believers’ exile is then the third in a layered cycle of exile. Having lost the paradise, believers tend to search for earthly paradises that they attach themselves to, and then tragically lose those as well. The thesis’ three primary literary texts …

The Cellular Mechanisms Of Alzheimer's Disease Protection By The Pilra G78r Variant, Wenhan Cheng

Theses and Dissertations

Microglial dysfunction is increasingly linked to Alzheimer’s Disease (AD). Immune receptors like TREM2 and CD33 play opposing roles in microglial activity. TREM2 activation triggers immunoreceptor tyrosine-based activation motif (ITAM) signaling to promote microglial activities, including amyloid-β clearance, but variants in TREM2 such as R47H that impair its function increase AD risk. In contrast, CD33 is an inhibitory receptor that contains an immunoreceptor tyrosine-based inhibitory motif (ITIM) which transmits signals that suppress microglial function. An AD-protective variant in CD33 alters CD33 activity, potentially enhancing TREM2 function. PILRA is another inhibitory immune receptor expressed by microglia that contains an ITIM. A naturally …

Implications Of The Mind’S Active Participation In The Formation Of Perception, Maikel Adel Samy Michael

Theses and Dissertations

The mind-body problem, particularly the issue of qualia, remains a fundamental challenge in understanding the nature of the mind and its relation to the body. In this thesis I argue that the problem is epistemic, stemming from how we perceive and know ourselves as physical and mental beings. This argument will be explored through the respective of idealisms proposed by George Berkeley and Immanuel Kant. Berkeley's idealism suggests that reality is rooted in perception, offering a major steppingstone by demonstrating the major role perception plays in understanding and acquiring knowledge. Kant contributes by asserting that the "thing-in-itself" is beyond our …

Practicality Of Implementing Sub-Clause 8.4 [Advance Warning] Of The Fidic 2017 Red Book In Egypt, Gehad Ibrahim

Theses and Dissertations

Disputes in construction projects can cause cost and time overruns that can be detrimental to the parties involved and to the project. Several measures have been advocated by the industry’s practitioners in an attempt to avoid disputes and their adverse impacts. One of these measures is the introduction of advance warning sub-clauses in construction contracts, where the contracting parties play a proactive and collaborative role in warning each other of potential adverse impacts to the project. Such clauses have been in the NEC suite of standard construction contracts for decades and have recently found their way to the 2017 edition …

The Instrumentalization Of The Unprivileged Combatants By Western Countries Aimed To Oppress National Liberation Wars, Fares Mahmoud Def-Allah Abdelhamid

Theses and Dissertations

The goal of International Humanitarian Law (IHL) is purported to be the humanization of wars. Nonetheless, the atrocities committed in wars and the war criminals’ impunity suggest the failure of IHL. Notwithstanding, some voices call for reforming and developing IHL. In contrast, this thesis argues that IHL should be rejected entirely since the distinction between privileged and unprivileged combatants indicates that IHL is biased against anti-colonizers. It is biased in three senses. Firstly, IHL, particularly the distinction between privileged and unprivileged combatants, is dominated by Western rationality, which can be noticed in the domination of the civilization concept with its …

This thesis explores the tangible impact of the green economy on Egypt's labor market by examining key sectors—automotive, agriculture, and renewable energy. Through qualitative interviews and focus group discussions with private sector representatives, the study assesses the true implications of the green transition from a business-level perspective, beyond the propaganda and hype surrounding climate policies. What is the current scale of the green economy in Egypt's labor market? What existing policies and regulatory frameworks are in place to support the green economy transition? how urgent is the transition to …

The Communal Lyric: Poetry In Devotional And Oppressed Communities, Michael N. Yacoub

Theses and Dissertations

This thesis investigates the interaction between lyric and community; it asks what a communal lyric is, how it functions, and to what ends. In Chapter One, I compare Jonathan Culler’s performative model of lyric with the theory of Takhyīl as expounded by Arab philosopher-critics al-Farabi, Ibn Sina, and al-Qartajanni to argue that a communal lyric is a form of audience-oriented public discourse distinguished by formal features that prompt the poem’s (re-)iteration and establish an interpersonal relationship with the audience in order to influence them and make shareable value claims about the world. In Chapters Two and Three I provide close-reading …

Theses and Dissertations

Introduction: Egypt's population, much like that of other countries, is expected to age considerably over the course of the coming decades. Although biological and socioeconomic predictors of cognitive function have been studied widely, personal level social capital remains unexplored, especially in LMICs.

Purpose: This study primarily investigates the relationship between individual social capital and cognitive functioning among older adults aged 65 years and older in Egypt using the structural and cognitive components of social capital, including group membership, civic engagements, and caregiving roles.

Methods: A cross-sectional survey on 363 older individuals in different geographical and demographic segments of Egypt using …

Finding Meaning In Loss: The Role Of Attachment Styles, Coping Strategies, And Resilience, Salma Seyam

Theses and Dissertations

Grief is a deeply personal yet universal experience impacted by personal, social, and cultural factors. The present study examines how attachment styles, coping mechanisms, and resilience impact both grief intensity and the ability to find meaning after a loss, within an Egyptian sample. While previous studies have explored the experience of grief, few have looked at these factors within a Middle Eastern cultural context. A total of 140 bereaved Egyptians who experienced the loss of a loved one within the past three years completed standardized measures assessing grief intensity (Prolonged Grief Disorder-Revised; PG-13-R), coping strategies (Brief COPE), meaning-making (Grief and …

Theses and Dissertations

In the past several decades, the rate of scientific and technological advancements in drug development and digital fields have been extraordinary. Internet of Things and block chain technologies are currently viable in the mature cloud computing industry, these transformative examples contrast starkly with the current pharmaceutical regulatory submission, review, and approval process of the EDA. However, with the emergence of initiatives that aim to improve and expedite regulatory decision-making, there is a promising future ahead. These initiatives, if successful, will not only transform the current transactional structure but also leverage scientific and technological advances to deliver patient-centric therapies. This radical …

Ways Of Living And Knowing, Reem El Hassan Mohamed

Theses and Dissertations

After decades of sedentarization, the Muzeina tribe in South Sinai now has new generations born into sedentary lifestyles, never experiencing nomadism like their ancestors once did. This shift has impacted their knowledge system, traditionally shaped by interactions and kinship with nature. Exposure to social media is influencing younger generations' ways of living, raising the older generations’ concerns about their Bedouin identity. Despite being one of the largest tribes in South Sinai, the Muzeina are rarely represented in literature.

This ethnography explores the impact of sedentarization and contextual developments on the Muzeina's knowledge system, inherited from their ancestors. Muzeina’s relationship, and …

Stuck In The Maze: Syrian Unaccompanied Children Navigating Spheres Of Protection In Egypt, Anouk Pelletier De Chambure

Theses and Dissertations

This research explores the protection of Syrian unaccompanied and separated children (UASC) in Egypt who have fled the Syrian conflict and reflects on the role of formal protection providers and informal networks of solidarity. In hopes of pushing back against the over- essentialization of UASC as vulnerable children, this research unravels the lived experiences of seven aged-out Syrian UASCs who have been living in Egypt for a few years, which reveals their authentic and original crafting of spheres of protection. This thesis aims to contribute to a more extensive and more accurate understanding of the lives and needs of Syrian …

A Tragedy Of Incommensurability: Indigenous Rights And The Limits Of Human Rights Law, Zeina Ali

Theses and Dissertations

This thesis explores the tragedy of incommensurability between indigenous rights and international human rights law. Despite the emergence of frameworks like the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP), indigenous calls for sovereignty remain fundamentally unintelligible within a liberal order structured to preserve settler-state legitimacy. Tracing the historical and theoretical evolution of indigenous advocacy, this study critiques the strategic shift from demands for self-determination to claims of cultural rights. It argues that this shift offers no real alternative: self-determination and cultural rights are functionally equivalent, as both are ultimately filtered through legal and political frameworks that cannot …

The Sealed Palace: How Direct Access To The Supreme Constitutional Court Can Bridge The Gaps In Constitutional Review In Egypt, Ahmed Sameh Fahmi

Theses and Dissertations

This thesis examines the limitations of Egypt’s current constitutional review system and argues for the introduction of a direct access mechanism to the Supreme Constitutional Court (SCC). Under Egypt’s centralized model of judicial review, individuals are restricted to indirect access through ordinary courts, which has resulted in significant procedural and substantive inefficiencies. The referral-based mechanism of judicial review of legislation has caused delays in adjudicating constitutional claims, the insulation of certain laws from review, legislative omissions, and excessive gatekeeping by lower courts. Through a comparative analysis of direct access models in Colombia, Germany, Turkey, and South Africa, the thesis identifies …

Growing Pains: Relations Between Racial Discrimination And Body Esteem With Ethnic-Racial Identity By Pubertal Timing For Female Adolescents Of Color, Emily J. Takamasa

Theses and Dissertations

Puberty is a near-universal experience among adolescents, and yet rarely have researchers considered the racialized contexts and salience it has, for girls of color. Using the phenomenological variant of ecological systems theory (PVEST), this study examines the relation between pubertal timing, body esteem, racial discrimination and ethnic racial identity (ERI) components (affirmation, exploration, resolution) among adolescent girls of color (n = 218, Mage = 15.7, U.S. sample). Results showed that higher body esteem predicted greater ERI exploration and resolution, particularly for girls with average or late pubertal timing. Additionally, racial discrimination was linked to higher ERI exploration and resolution only …

Predicting Secondary Mathematics-For-Teaching Knowledge Using Beliefs, Experience, And School Culture: A Hierarchical Regression Analysis, Adam R. Brulhardt

Theses and Dissertations

Research in recent decades has supported the notion that practice-based mathematical knowledge is crucial for effective teaching, playing an important role in enacting reform-oriented instruction required for improving student achievement. Despite its importance, teachers—especially novices—require more support in acquiring such knowledge, an ongoing challenge exacerbated by teacher shortages. The purpose of this quantitative study was to determine whether collaborative school culture (CSC) explained variance in knowledge of algebra for teaching (KAT) beyond variance explained by mathematics-related beliefs and years of teaching experience for U.S. secondary teachers. Measures within an online Qualtrics survey included the Beliefs About Mathematics and Teaching Scale …

Quantum-Chemical Modeling Of Mechanisms And Selectivity In Open-Shell Organometallic Reactions, Michael T. Davenport

Theses and Dissertations

Quantum mechanical calculations have emerged as a powerful approach for directly evaluating reaction mechanisms and selectivity in transition metal-ligand complexes involving organometallic intermediates. Density functional theory (DFT) quantum mechanical methods enable the generation of potential energy surfaces and structures that define reaction mechanisms and allow for the evaluation of selectivity through statistical transition state theory. However, in certain cases, it is necessary to go beyond statistical treatments and incorporate atomic motion through molecular dynamics simulations. Additionally, many transition metal-mediated reactions involve unpaired electrons and spin state crossings. This dissertation focuses on the application of DFT-derived potential energy surfaces and molecular …

Rapid Beamformer Weight Calibration Update Method For The Advanced L-Band Phased Array Camera For Astronomy (Alpaca), Kayla Lyman Ward

Theses and Dissertations

The Advanced L-Band Phased Array Camera for Astronomy (ALPACA) is a phased array feed instrument designed for the Green Bank Telescope. It is capable of producing 40 real-time beams on the sky, widening the telescope's field of view and significantly increasing survey speed. ALPACA employs an RF-over-fiber (RFoF) signal transport system from the phased array feed front end to the digital backend. This RFoF link is expected to introduce phase delays and changes in gain through out the course of an observation, invalidating the beamformer weights previously calculated. This work presents rapid beamformer weight calibration updates for ALPACA, a method …

Expanding A Standardized Reading Program Utilizing Research-Based Literacy Practices, Culturally Responsive Teaching, And Teacher Decision Making, Jacalyn Marie Gizara

Theses and Dissertations

The reading achievement disparities between diverse learners and their advantaged peers has been at the forefront of education for decades (Hammond, 2015; Kelley et al., 2015; Ladson-Billings, 2006; Paschall et al., 2017; Pitre, 2014). Educational policies have attempted to close the achievement gap and address the inequitable practices school systems place on our youth (Paschall et al, 2017; Pitre, 2014). However, teachers can lead in the profession and create positive change for students’ school experiences and learning outcomes. The purpose of this action research study was to enhance the prepackaged reading program with thematic units, culturally responsive teaching, and research-based …
