Neural Stem Cells: Age-Dependent Outcomes During Viral Infections In The Central Nervous System, Manisha N. Chandwani

Electronic Theses and Dissertations

Viral infections in the central nervous system (CNS) are associated with neurodevelopmental and neurobehavioral deficits. The outcomes of viral infections can be driven by damage and death of neurons. Neural stem cells (NSCs) play key roles in neurodevelopment, repair, and physiological brain function. During a viral infection, NSC activity can disturbed by direct infection of NSCs by the virus or by anti-viral immune response. Here, we aimed to assess whether the anti-viral immune response can impact NSC activity during an immunocompetent response in the adult brain. We utilized a transgenic mouse model of Measles virus infection where only the CNS …

Properties And Classifications Of Certain Lcd Codes., Dalton Seth Gannon

Electronic Theses and Dissertations

A linear code $C$ is called a linear complementary dual code (LCD code) if $C \cap C^\perp = {0}$ holds. LCD codes have many applications in cryptography, communication systems, data storage, and quantum coding theory. In this dissertation we show that a necessary and sufficient condition for a cyclic code $C$ over $\Z_4$ of odd length to be an LCD code is that $C=\big( f(x) \big)$ where $f$ is a self-reciprocal polynomial in $\Z_{4}[X]$ which is also in our paper \cite{GK1}. We then extend this result and provide a necessary and sufficient condition for a cyclic code $C$ of length …

Media Portrayal Of Private Prisons And Inmates., Ladye Anna L. Adams

Electronic Theses and Dissertations

Private prisons have existed in the United States since 1986, but research about prison privatization has been limited. To date, there have been two published studies examining how mainstream media sources frame prison privatization to their audiences. This thesis attempts to address this gap in the literature. Using content analysis, I evaluate how mainstream media frames prison privatization and inmates housed in private prisons. The analysis is conducted in two parts. The first tests if private prison reduction or expansion is the focus of the news story if framed using economic benefits, ethical concerns, or prisoner violence. The second tests …

Voices Of The "Served": Community Resident Perspectives On International Service-Learning In Peru., Adam C. Stieglitz

Electronic Theses and Dissertations

The purpose of this study is to capture and share community resident perspectives on international service-learning (ISL).

Characterization Of Microbotryum Lychnidis-Dioicae Secreted Effector Proteins That Manipulate Its Host Plant, Silene Latifolia., Ming-Chang Tsai

Electronic Theses and Dissertations

The smut fungal species Microbotryum lychnidis-dioicae is an obligate phytopathogen colonizing the plant host, Silene latifolia. A significant feature of M. lychnidis-dioicae infection is that the fungus can replace pollen on the anthers of susceptible host plants with fungal teliospores, thus earning the fungus the name: anther smut disease of flowers. The fungus synthesizes and secretes effector proteins into the cells of the plant host during infection, and the protein-protein interactions may interfere with and modify metabolism, plant development, and gene expression of the host to allow fungal colonization. Two potential fungal effector proteins, MVLG_06175 and MVLG_05122, were identified …

Electronic Theses and Dissertations

ACEs have been associated with heightened risk for a range of chronic health problems, substance use, and cognition in adulthood (Center for Disease Control (CDC), 2019; Hinojosa et al., 2017). One potential protective factor is physical activity (McEwen, 2016; Wu et al., 2013). Physical activity is associated with sustaining overall health, improving mental health by reducing symptoms of depression and anxiety (Murri et al., 2019; Sharma et al., 2006; Tasci et al., 2019), and maintaining a healthy body weight and BMI (WHO, 2021). Therefore, this study examined whether barriers to physical activity, physical activity levels, and executive outcomes serve as …

An Investigation Of The Relationship Between Teachers’ Personal Epistemologies And Their Self-Efficacy About Culturally Responsive Classroom Management, Tahani Ahmed

Electronic Theses and Dissertations

Diversity is now an essential matter in US public schools. For the first time in America's history, students of color will constitute a majority of the public school enrollment; on the other hand, most early childhood and elementary teachers remain monolingual, white, middle-class females (Hussar & Bailey, 2019). The demographic mismatch between students and teachers presents a critical concern for teacher preparation programs (Banks et al., 2005; Gay, 2018; Muñiz, 2019). Therefore, this study proposed that understanding the relationship between pre-service teachers' epistemological beliefs and their culturally responsive classroom management self-efficacy illustrated factors that may improve their teaching concept toward …
