Supporting Teacher Retention Through a Trauma-Informed Lens
This thesis explores the relationship between trauma-informed practices and teacher burnout and turnover. For the past decade, schools across the United States have seen high levels of burnout and turnover amongst their educators. At the same time, young children are experiencing high levels of exposure to traumatic events in childhood, affecting their behavior, social and emotional health, and ability to learn. While teachers play an important role in the support system for these students, they are also at risk for experiencing secondary trauma and burnout. To mitigate the effects of trauma, trauma-informed practices have been introduced in schools to respond to trauma and build resiliency in both students and teachers. In Pennsylvania, some school districts have received funding to implement trauma-informed practices through the PA School Safety and Security Grant program. This research studies the influence of trauma-informed practices funded by the grant program on teacher burnout, measured using the Maslach Burnout Inventory-Educator Survey, and teacher turnover, using mixed quantitative and qualitative methods. The results indicate that teachers in Pennsylvania are experiencing burnout, particularly emotional exhaustion, but that there were no differences in burnout levels or intended turnover between teachers who taught in schools with the grant for trauma-informed practices and those that did not. Implications for further policy are discussed, including suggestions for implementing tiered whole-school models of trauma-informed practices to support both students who have experienced trauma and the teachers that work with them
Pre-Service Teacher Preparation in Trauma-Informed Pedagogy: A Review of State Competencies
Trauma-informed pedagogy recognizes childhood trauma and its influence on students’ behavior, health, and ability to learn. By utilizing trauma- informed pedagogy, teachers can help children who have experienced trauma build resiliency. To determine if pre-service teachers are being trained in trauma-informed pedagogy, a systematic review of state-level teacher competency policies from all 50 states and Washington, D.C. was conducted. These teacher competencies were coded for the presence of elements of trauma-informed pedagogy. The review has shown that five states require teacher training in trauma-informed pedagogy and far more require training in individual elements, including social-emotional learning and cultural responsiveness
Trauma-Informed Practices: A Whole School Policy Framework
State leaders should take action to ensure that teachers are prepared to address the needs of children who have experienced traumatic events
Endosomal integrin signals for survival.
The mechanisms underlying integrin-dependent signalling are a topic of continued study. Endocytosed integrins are now shown to drive assembly of signalling complexes on the cytoplasmic face of endocytic membranes to promote cancer cell survival and increase metastatic capacity following cell detachment
Colorectal Hyperplasia and Dysplasia Due to Human Carcinoembryonic Antigen (CEA) Family Member Expression in Transgenic Mice
CEA and CEACAM6 are immunoglobulin family intercellular adhesion molecules that are up-regulated without structural mutations in approximately 70% of human cancers. Results in in vitro systems showing tumorigenic effects for these molecules suggest that this correlation could indicate an instrumental role in tumorigenesis. To test whether this applies in vivo, transgenic mice harboring 187 kb of the human genome containing four CEA family member genes including the CEA and CEACAM6 genes were created and their copy numbers increased by mating until colonocyte expression levels reached levels seen in human colorectal carcinomas. The colonocyte surface level of integrin α5 and the activation of AKT increased progressively with the expression levels of CEA/CEACAM6. Colonic crypts showed a progressive increase in colonocyte proliferation, an increase in crypt fission, and a strong inhibition of both differentiation and anoikis/apoptosis. All transgenic mice showed massively enlarged colons comprising a continuous mosaic of severe hyperplasia, dysplasia and serrated adenomatous morphology. These results suggest that up-regulated non-mutated adhesion molecules could have a significant instrumental role in human cancer
A mutation in Nischarin causes otitis media via LIMK1 and NF-κB pathways
Otitis media (OM), inflammation of the middle ear (ME), is a common cause of conductive hearing impairment. Despite the importance of the disease, the aetiology of chronic and recurrent forms of middle ear inflammatory disease remains poorly understood. Studies of the human population suggest that there is a significant genetic component predisposing to the development of chronic OM, although the underlying genes are largely unknown. Using N-ethyl-N-nitrosourea mutagenesis we identified a recessive mouse mutant, edison, that spontaneously develops a conductive hearing loss due to chronic OM. The causal mutation was identified as a missense change, L972P, in the Nischarin (NISCH) gene. edison mice develop a serous or granulocytic effusion, increasingly macrophage and neutrophil rich with age, along with a thickened, inflamed mucoperiosteum. We also identified a second hypomorphic allele, V33A, with only modest increases in auditory thresholds and reduced incidence of OM. NISCH interacts with several proteins, including ITGA5 that is thought to have a role in modulating VEGF-induced angiogenesis and vascularization. We identified a significant genetic interaction between Nisch and Itga5; mice heterozygous for Itga5-null and homozygous for edison mutations display a significantly increased penetrance and severity of chronic OM. In order to understand the pathological mechanisms underlying the OM phenotype, we studied interacting partners to NISCH along with downstream signalling molecules in the middle ear epithelia of edison mouse. Our analysis implicates PAK1 and RAC1, and downstream signalling in LIMK1 and NF-κB pathways in the development of chronic OM
