Parent Advocacy For Literacy Intervention: A Case Study Of Motivations And Experiences, Meghan Malloy

All Dissertations

While systems of support are used in schools to assist students’ academic growth, parents are not always informed of the support process or the academic goals set for their child (RTI Action Network, n.d.; Troisi, 2014; Weingarten et al., 2020). In the aftermath of the pandemic, students present a wide variety of academic needs (Lewis et al., 2021; Maldonado & De Witte, 2020), underscoring the importance of parent advocacy. In situations where a student needs additional supports, such as literacy intervention, the parent may become the child’s best advocate (Besnoy et al., 2015).

Fundamental Study Of Nonlinear Electrophoresis, Joseph Armakan Bentor

All Dissertations

Classical electrophoretic theory describes the linear response of particles suspended in Newtonian fluids under weak electric fields. When the electric field exceeds this weak limit, a nonlinear response arises due to non-uniform surface conduction over the curved particles. This nonlinear behavior introduces dependencies on fluid and particle properties not considered in the classical theory, offering potential advantages for microfluidic particle manipulation. While this phenomenon has been extensively studied theoretically and numerically in Newtonian fluids, experimental investigations have been relatively limited.

Fluid rheology can significantly alter particle dynamics under applied electric fields. Rheological properties like shear-thinning and elasticity which are not …

Antiracism In Higher Education: An Integrated Psychological Perspective, Rhea E. Nesbitt

Dissertations, 2020-current

Antiracism is a complicated and important term with prominent, influential voices claiming that systemic equity and the reconfiguration of white identity are the central solutions to eradicating American racism. Within the profound sociocultural effects of the existing antiracist rhetoric, there is vagueness, conflict, and incoherence. Language serves as a fundamental aspect of human experience, facilitating individual meaning-making and comprehension. Effective communication hinges on the ability to articulate subjective experiences and justifications clearly, a challenge evident in discussions surrounding antiracism. Despite advocating for antiracism as crucial and unending work, scholars recognize significant hurdles, including unclear responsibilities for implementation and entrenched structures …

Candida Albicans Farnesol Synthesis And Secretion, Daniel J. Gutzmann

School of Biological Sciences: Dissertations, Theses, and Student Research

Candida albicans is a polymorphic fungus and opportunistic commensal found primarily in the gastrointestinal and skin of healthy individuals. Several barriers prevent C. albicans from causing disease including a healthy immune system and microbiome. When these barriers become comprised, C. albicans can transition to a pathogen and disseminate through the intestinal mucosa leading to life-threatening bloodstream and invasive infections with mortality rates of up to 64%. Morphogenic plasticity is key to this transition and impacts virulence, adaptation to different host environments, and evasion of host immune responses. One regulator of morphogenesis is farnesol. Farnesol is a secondary metabolite of …

Exposing The Pervasive Culture Of Whiteness At Predominantly White Institutions: A Narrative Analysis Of White Deans Of Students' Understanding And Role In Responses To Campus Racial Incidents, Jennifer Helen Reid

Graduate Doctoral Dissertations

Deeply embedded in U.S. higher education institutions is a culture of whiteness that benefits white students, staff, faculty, and administrators through racist policies, structures, and cultural norms designed to uphold whiteness. This culture not only minimizes the presence of racism, but also is pervasive on college campuses, where administrators often fail to recognize blatant racism and treat ongoing campus racial incidents as isolated events. Despite the frequency of racial incidents, campus responses are typically ineffective, failing to address the underlying institutional practices that reinforce white supremacy and further harm those affected. This study explored the experiences of white deans of …

Advancing Methods For Studying The Neuroscience Of Sex Variability And Diversity, Vic Shao-Chih Chiang

Graduate Doctoral Dissertations

Sex variability and diversity are pervasive across taxa and genera. Society is heavily structured around sex/gender conceptualizations, and neuroscience research actively shapes these constructs. This dissertation adopts frameworks that challenge ideologies perpetuating sex/gender injustices and developed neuroscience-related methodologies that could advance the conceptualisations of sex. First, I studied B6D2F1 mice which exhibit sexual behaviour months after castration. This challenged the dogma that sexual behaviour is dependent on gonadal steroid hormones. I enhanced the behavioural analysis of these mice using deep learning techniques. Second, applying similar deep learning methods, I refined the behavioural analysis of Astatotilapia burtoni cichlids, which exhibit sexual …

Biological Sex Influences Daily Locomotor Rhythms In Mice Held Under Different Housing Conditions, Amanda Pastrick, Matthew Diaz, Griffin Adaya, Victoria Montinola, Madeline Arzbecker, Deborah A. M. Joye, Jennifer A. Evans

Biomedical Sciences Faculty Research and Publications

Daily rhythms are programmed by a central circadian clock that is modulated by photoperiod. Here, we recorded locomotor activity rhythms in C57Bl/6 or mPer2^Luc mice of both sexes held under different housing conditions. First, we confirm that the structure of locomotor activity rhythms differs between male and female mice in both genetic backgrounds. Male mice exhibit a nightly “siesta,” whereas female mice fluctuate between nights with and without a nightly siesta, which corresponds with changes in locomotor activity levels, circadian period, and vaginal cytology. The nightly siesta is modulated by the presence of a running wheel in both sexes …
