An Interpretive Phenomenological Analysis Of Counselor's Experience Of Breathwork And Its Impact On Their Therapeutic Practice, Jennifer Zúñiga Agüero

Dissertations

Breathwork, a transpersonal and experiential approach to psychotherapy, has been used for healing and transformation throughout the years. When applied in clinical practice, breathwork can serve as a conduit to access nonordinary states of consciousness for self-exploration and transformation. Traditional psychotherapy does not engage with nonordinary states of consciousness as part of the therapeutic process; thus, research in relation to counselors’ experiences of breathwork and their impact on therapeutic practice has yet to be explored.

Counselors’ experiences of breathwork and the influence they have in clinical practice is the phenomena explored in this research study. Exploring counselor experience with a …

Despite this importance, research studies have suggested a divergence between actual practice and the ideal expectation from practitioners. Therefore, it was imperative to establish the ground truth in this context and explore the reasons behind the gap between practice and expectation. This mixed-method study used a survey and interviews to establish that only a small fraction of practitioners consistently …

School Psychologists’ Experiences And Roles In Trauma-Informed Practices, Taylor Williamson

Discerning The Role Of Microtubule Acetylation During Hiv-1 Infection, Drew Michael Lichon

Dissertations

The host-pathogen interactions underlying Human Immunodeficiency Virus type 1 (HIV-1) infection are complex and involve the exploitation of host cellular machinery. This thesis investigates the roles of dynein adaptors, microtubule acetylation, and TRIM69-mediated restriction in HIV-1 infection. Through a series of detailed experiments, we explore how HIV-1 utilizes multiple dynein adaptors, such as BICDR1 and Hook3, for intracellular transport, and reveal that these adaptors are critical for efficient viral trafficking. Conversely, the knockdown of Ninein surprisingly enhances HIV-1 infectivity, suggesting a nuanced regulatory role for this adaptor in viral transport. Further, this thesis challenges the prevailing paradigm that microtubule acetylation …
