The Effects Of Caregiving For A Family Member With Alzheimer’S Disease, Megan Layton

Student Works

Alzheimer’s disease (AD) is a progressive disease that leads people with AD to become dependent on a family member. As the disease worsens, caregivers face an increase in responsibility and burden. There is a rising number of AD cases which will result in an increase of caregivers. Twelve articles were examined using the EBSCO database by using keywords such as “Alzheimer’s disease,” “caregiver burden,” “coping,” “assisted living,” and “grief.” An analysis of these articles indicated the complexities of caregiving for a loved one with AD. These complexities such as stress, decision-making challenges, changes in family dynamics, the adjustment to placing …

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 …

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 …

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 …

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 …

Developmental Consequences Of Benevolent Sexism: How Awareness Can Change Women’S Lives, Bianca F. Brenes Rojas

Student Works

Benevolent forms of sexism become increasingly evident as society evolves, making everyday sexism more challenging to recognize and confront (Feigt et al., 2022; Watson et al., 2018). When unaware, benevolent forms of sexism can adversely affect women’s self-esteem, create feelings of inferiority, and may potentially increase women’s psychological stressors (Becker & Swim, 2011; Becker & Wright, 2011; Moradi & Subich, 2004). According to the ambivalent sexism theory, benevolent forms of sexism, while expressed in a positive tone, can potentially affect women due to the underlying belief that women are inferior to men (Glick & Fiske, 1996). Some women perceive benevolent …

Multi-Field Quantum Conference Key Agreement Using An Integrated Photonic Green Machine, Benjamin J. Fisher

Theses and Dissertations

Quantum Conference Key Agreement (QCKA) enables a group of users to generate a shared secret key, which reduces the latency and equipment overhead of establishing multiple Quantum Key Distribution (QKD) links. Conventional QCKA protocols send a multi-photon entangled state from one user to others and a key is generated only when all photons are detected, which is inefficient at high loss and opens side-channels at the receiver side. Here, we overcome this barrier through a multi-field QCKA protocol enabled by designing, fabricating, and testing an integrated photonic Green Machine that implements an eight-mode Hadamard unitary transformation through a beam-splitter network. …

Who's On The Phone: Effectiveness Of Cloned Vishing Messages, Katherine A. Rackliffe

Undergraduate Honors Theses

Voice cloning is increasingly used as a form of phone-based phishing attack (i.e., vishing attack). The purpose of this research is to understand the impact of voice cloning on the success rate of vishing/phishing attacks. We hypothesize that calls utilizing cloned voices are more likely to deceive recipients compared to traditional vishing calls or text messages with the same phishing content. As AI cloning is a new technology, there is not much literature on this topic.

Exploring Consequences Of The Double Empathy Problem Across The Autistic Trait Spectrum: First Person Accounts, Cammy C. Peck

Theses and Dissertations

Historically, individuals on the autism spectrum were believed to have deficits in empathy. However, recent research suggests that empathy-related issues occur on both sides of the communication dynamic. This concept known as the Double Empathy Problem (DEP), posits that the perceived lack of empathy is not exclusive to autistic individuals; rather, neurotypical (NT) individuals also experience difficulty empathizing with autistic individuals (Milton, 2012). Milton et al. (2022) describes this as a "breakdown in mutual understanding". Such mutual misunderstanding can have adverse consequences for both autistic and neurotypical individuals. To our knowledge, no studies have directly examined these consequences in relation …
