Examining Mental Health Professionals' Attitudes Towards Individuals With Rural Accents, Emily Heavner

Theses and Dissertations

Bias against people from rural areas is ingrained in American culture, and stereotypes that people from rural regions are backwards, uneducated, and unintelligent are prevalent (Fulkerson & Thomas, 2016; Hartman et al., 2023; Howley, 2009; Shirley, 2010). Many people from rural areas have accents that mark them as coming from a rural region (Flanigan, 2000). Research suggests that accent is a reminder that the speaker is from a different cultural group than the listener, triggering biases and stereotypes about the speaker (Chakraborty, 2017). Because accent and rural culture are not often discussed as part of multicultural competence, many mental health …

Maturational Changes In The Epigenome And Transcriptome Of Hypothalamic Astrocytes: Implications For Axonal Regeneration, Abiodun Ebenezer Odufuwa

Theses and Dissertations

Axon regeneration is essential for effective repair following injury in the CNS. One of the burdens of aging is the lack of recovery following injury in the CNS. Our previous studies show that in 35-day-old rats, axon regeneration occurs in response to a unilateral hypothalamic lesion in the hypothalamus neurohypophyseal system. However, this regenerative ability is lost in 125-day-old rats. Furthermore, treatment of hypothalamic organotypic culture with ciliary neurotrophic factor (CNTF) promotes axonal outgrowth and survival. Our previous studies suggest that astrocytes may be playing critical roles in this maturational loss of regenerative capacity because only astrocytes expressed all the …
