School Leader Perceptions About The Implementation And Utility Of Restorative Practices, Danielle Rutig

Electronic Theses and Dissertations

This phenomenological qualitative study examined school leaders' perceptions of using restorative practices within their schools. Participants included twelve school leaders who had experience with utilizing and implementing restorative practices. School leaders included: principals, assistant principals, deans, and administrative assistants. Research indicates that restorative practices are adapted to support specific school goals. Restorative practices are not practiced in isolation, as school leaders often couple restorative justice with social-emotional learning, trauma-informed practices, and other social-emotional supports. Restorative practices are tied closely to CASEL’s social emotional framework.

Data were collected via semi-structured interviews using a virtual platform. Themes that emerged from the analysis …

Met Alterations In Glioblastoma: Characterization Of Patient-Derived Xenografts And Therapeutic Strategies, Anna Musket

Electronic Theses and Dissertations

Glioblastoma is the most commonly diagnosed central nervous system primary malignancy and it is considered a terminal diagnosis with few treatment options available. Glioblastoma tumors frequently develop treatment resistance due in part to their highly heterogenic nature. The heterogeneity of glioblastoma is partially attributed to the presence of glioma stem-like cells (GSC), which are highly invasive and resistant to chemotherapy and irradiation treatments. Signaling of the receptor tyrosine kinase MET is a known regulator of GSC. Glioblastoma patients have an increasingly poor prognosis that corresponds with increasing MET expression. Both GSC and MET are known to contribute to treatment resistance …

A Pandemic’S Potential To Haunt: A Longitudinal Look At The Professional Wellbeing Of Tn’S Infant And Early Childhood Mental Health (Iecmh) Workforce, Robyn A. Dolson

Electronic Theses and Dissertations

Infant and Early Childhood Mental Health (IECMH) providers engage in uniquely relational work with high-risk families that expose them to the full advantages (i.e., compassion satisfaction [CS]) and disadvantages (e.g., burn-out [BO]) of a helper role. Though the pandemic seemed poised to escalate disadvantage, most early pandemic studies found high CS alongside elevated BO. Unfortunately, as COVID-19 has continued, CS has declined while BO has increased. Given the delayed COVID-19 impact on children, these changes may be particularly acute for IECMH providers. Using a longitudinal cohort of 27 IECMH providers, this study aimed to describe and quantify changes in professional …

Femoral Osteohistology In American Alligators (Alligator Mississippiensis) Reveals High Variation In Growth And Facilitates Interpretation Of An Early Pliocene Alligator, Davis Gunnin

Electronic Theses and Dissertations

Histological analysis of long bone thin sections is commonly used to infer growth rates and ecology of extinct vertebrates, particularly within Archosauria. However, most comparative neontological studies have used small samples of captive individuals, limiting the scope of variation. To fill this gap, 44 femoral thin sections of wild Alligator mississippiensis were prepared and analyzed. Comparison of slides revealed that larger individuals from cooler climates tend to show more LAGs compared to southerly A. mississippiensis of similar size, however, there is considerable variation. This pronounced variation in wild specimens emphasizes the need to use caution when interpreting paleohistological data with …

Rethinking Bibliotherapy: Portraits Of Gifted Adult Readers, Jervaise M. Pileggi

Electronic Theses and Dissertations

Gifted individuals have unique socioemotional needs due to their sensitivity and intensities. Bibliotherapy is often recommended to gifted persons to help them understand themselves and others and to address affective needs. However, bibliotherapy’s roots are embedded within a clinical background, thus requiring an element of discussion. Instead, I argue that gifted adults use metacognition to replace the need for discussion. Portraits of gifted adult readers (N=7) in their 30s-50s illustrate that metacognition has occurred over their lifespan regarding their reading, with only one participant actively engaging in discussion, and book selection meets the socioemotional needs of the reader. The findings …
