The Role Of Trauma-Related Shame In Ptsd And Dissociation, Alexis Stokes

Bakerman Student Research Awards

Dissociation commonly occurs in response to traumatic events, and a dissociative subtype of PTSD is now recognized in the DSM-5. However, researchers have not established a clear consensus as to what factors separate individuals with general PTSD and PTSD with dissociative symptoms (PTSD-D). Negative affect—specifically shame—has been increasingly examined in psychotraumatology research. There is ample evidence that shame predicts and maintains symptom severity in PTSD patients, as well as that it can induce and maintain dissociative symptoms. The clear connection of shame to PTSD and dissociation suggests that it may be an important factor for conceptualizing PTSD-D; however, there is …

Co2 Capture Utilizing Novel Deep Eutectic Solvents: Modeling, Process Simulation, And Cost Analysis, Nazneen Aspi Kolah

Removing Methane Via Soil Amendments: The Legal Framework, Korey Silverman-Roati, Romany M. Webb

Sabin Center for Climate Change Law

Rapid and sustained reductions in human-driven methane emissions are critical to limiting warming in line with the 2015 Paris Agreement. Reductions in certain methane emissions, particularly from the fossil fuel sector, can be implemented cheaply and efficiently. Other forms of methane emissions, like those from agricultural sources, are more difficult to control. This fact, coupled with concerns that climate change could unlock significant additional natural emissions from tropical wetlands and melting permafrost, has increased interest in atmospheric methane removal (“AMR”).

AMR refers to human interventions to accelerate the conversion of methane in the atmosphere to a form that causes less …

Faculty Journal Articles

Chemoresistance and severe toxicities represent major drawbacks of chemotherapy. Natural extracts, including the essential oils of Pistacia lentiscus (PLEO), exhibit substantial anticancer and anti-inflammatory activities where different cancers are reported to dramatically recess following targeting with PLEO. PLEO has promising antimicrobial, anticancer, and anti-inflammatory properties. However, the therapeutic properties of PLEO are restricted by limited stability, bioavailability, and targeting ability. PLEO nanoformulation can maximize their physicochemical and therapeutic properties, overcoming their shortcomings. Hence, PLEO was extracted and its chemical composition was determined by GC–MS. PLEO and 5-Fluorouracil (5FU) were electrospun into poly-ε-caprolactone nanofibers (PCL-NFs), of 290.71 nm to 680.95 nm …

Suicidality: The Role Of The Workplace, Hailey Carroll

All Theses

Suicide is a major issue in the world today. Complex reasons explain why some people have higher levels of suicidal ideation or attempts than others. One theory that posits answers to why people die by suicide is the Interpersonal Theory of Suicide (IPTS). This theory states that thwarted belongingness (TB) and perceived burdensomeness (PB) work together to lead to suicidal ideation. The relationship between suicidal ideation and suicide attempts is moderated by the capacity for suicide. The current study sought to expand upon this theory, questioning what role the workplace plays in one’s suicidality. Specifically, the study looked at mattering …
