Bibliotherapy In The Helping Professions: A Heuristic Model For Intervention Design, Natalie Marie Haney Dec 2022

Bibliotherapy In The Helping Professions: A Heuristic Model For Intervention Design, Natalie Marie Haney

Masters Theses

I propose a new approach to examining bibliotherapy’s usefulness in the community-based care of individuals with serious mental illness (SMI), focused on producing a heuristic that benefits helping professionals who offer non-clinical and non-psychiatric services. Meant for writers designing bibliotherapy interventions in the helping professions, I conceptualize bibliotherapy in a model against the backdrop of community-based care’s history. A model has the potential to allow each writer to conduct situation-specific inquiry, invent bibliotherapy intervention designs suited to the unique needs of the profession’s help-seekers, and reflect on knowledge generated for intervention reiteration. Referring to Dewey, Rosenblatt and Barnlund to create …

Relationship Of Cognition And Alzheimer’S Disease With Gastrointestinal Tract Disorders: A Large-Scale Genetic Overlap And Mendelian Randomisation Analysis, Emmanuel O. Adewuyi, Eleanor K. O’Brien, Tenielle Porter, Simon M. Laws

Research outputs 2022 to 2026

Emerging observational evidence suggests links between cognitive impairment and a range of gastrointestinal tract (GIT) disorders; however, the mechanisms underlying their relationships remain unclear. Leveraging large-scale genome-wide association studies’ summary statistics, we comprehensively assessed genetic overlap and potential causality of cognitive traits and Alzheimer’s disease (AD) with several GIT disorders. We demonstrate a strong and highly significant inverse global genetic correlation between cognitive traits and GIT disorders — peptic ulcer disease (PUD), gastritis-duodenitis, diverticulosis, irritable bowel syndrome, and gastroesophageal reflux disease (GERD), but not inflammatory bowel disease (IBD). Further analysis detects 35 significant (p < 4.37 × 10 − 5) bivariate local genetic …

Image fusion of CT, MRI, and PET with endoscopic ultrasound and transabdominal ultrasound can be promising for GI malignancies as it has the potential to allow for a more precise lesion characterization with higher accuracy in tumor detection, staging, and interventional/image guidance. We conducted a literature review to identify the current possibilities of real-time image fusion involving US with a focus on clinical applications in the management of GI malignancies. Liver applications have been the most extensively investigated, either in experimental or commercially available systems. Real-time US fusion imaging of the liver is gaining more acceptance as it enables further …


Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev Dec 2022

Accumulation Of Sublethal Radiation Damage And Its Effect On Cell Survival, Oleg N Vassiliev

Faculty, Staff and Student Publications

Objective. Determine the extent of sublethal radiation damage (SRD) in a cell population that received a given dose of radiation and the impact of this damage on cell survival. Approach. We developed a novel formalism to account for accumulation of SRD with increasing dose. It is based on a very general formula for cell survival that correctly predicts the basic properties of cell survival curves, such as the transition from the linear-quadratic to a linear dependence at high doses. Using this formalism we analyzed extensive experimental data for photons, protons and heavy ions to evaluate model parameters, quantify the extent …


Reflecting On The Advancements Of Hfref Therapies Over The Last Two Decades And Predicting What Is Yet To Come, Iliana L. Piña, Gregory T. Gibson, Shelley Zieroth, Rachna Kataria Dec 2022

Reflecting On The Advancements Of Hfref Therapies Over The Last Two Decades And Predicting What Is Yet To Come, Iliana L. Piña, Gregory T. Gibson, Shelley Zieroth, Rachna Kataria

Division of Cardiology Faculty Papers

What was once considered a topic best avoided, managing heart failure with reduced ejection fraction (HFrEF) has become the focus of many drug and device therapies. While the four pillars of guideline-directed medical therapies have successfully reduced heart failure hospitalizations, and some have even impacted cardiovascular mortality in randomized controlled trials (RCTs), patient-reported outcomes have emerged as important endpoints that merit greater emphasis in future studies. The prospect of an oral inotrope seems more probable now as targets for drug therapies have moved from neurohormonal modulation to intracellular mechanisms and direct cardiac myosin stimulation. While we have come a long …

The Role Of Lncrnas In The Tumor Microenvironment And Immunotherapy Of Melanoma, Wencheng Zhou, Xuewen Xu, Ying Cen, Junjie Chen

Faculty, Staff and Student Publications

Melanoma is one of the most lethal tumors with highly aggressive and metastatic properties. Although immunotherapy and targeted therapy have certain therapeutic effects in melanoma, a significant proportion of patients still have drug resistance after treatment. Recent studies have shown that long noncoding RNAs (lncRNAs) are widely recognized as regulatory factors in cancer. They can regulate numerous cellular processes, including cell proliferation, metastasis, epithelial-mesenchymal transition (EMT) progression and the immune microenvironment. The role of lncRNAs in malignant tumors has received much attention, whereas the relationship between lncRNAs and melanoma requires further investigation. Our review summarizes tumor suppressive and oncogenic lncRNAs …


Not So Civil Commitment: A Proposal For Statutory Reform Grounded In Procedural Justice, Margaret J. Lederer Dec 2022

Not So Civil Commitment: A Proposal For Statutory Reform Grounded In Procedural Justice, Margaret J. Lederer

Duke Law Journal

Every year, millions of Americans struggle with serious mental illness. Of them, thousands experience civil, or involuntary, commitment—that is, hospitals invoke the coercive power of the state to force these individuals into psychiatric hospitals against their will. Whether someone requires hospitalization is a complex question of psychology, medicine, and substantive law.

But the process of civil commitment itself is troubling. Across the board, states fail to afford those facing civil commitment meaningful procedural protections. Current state laws subject individuals facing commitment to extended periods of confinement with little to no judicial intervention. Indeed, individuals facing commitment may wait weeks or …


Metallacycle-Mediated Cross-Coupling As An Enabling Tool For Studies In Carbocycle Synthesis And Functionalization, Adam Barry Millham Dec 2022

Metallacycle-Mediated Cross-Coupling As An Enabling Tool For Studies In Carbocycle Synthesis And Functionalization, Adam Barry Millham

Dartmouth College Ph.D Dissertations

Natural products, specifically complex, carbocyclic natural products, have served as the inspiration for novel methods development for decades. Over that time, metallacycle-mediated cross-coupling has arisen as a powerful means for the synthesis of fused carbocycles. This work details three methods for the synthesis and functionalization of carbocyclic motifs that have been enabled by Ti-mediated cross-coupling reactions. The first of these studies include a complementary method to the Pauson–Khand reaction for the synthesis of highly substituted cyclopentenones via Ti-mediated alkyne–β-ketoester coupling. The second project, a modern approach to steroidal tetracycles, will be discussed that features: (1) an alkoxide-directed metallacycle-mediated [2+2+2] annulation …

The Influence On American Post-Secondary Education By United States Military And Veteran Programs Resulting From Changing Technology, Reform-Minded Leaders, And Large Military Operations, Scot Douglas Cates

Doctoral Dissertations and Projects

Scholars have explored the United States military from the lens of battles, campaigns, operations, and leaders with depth and zeal. When discussing the influence of the Army on education in America, the G.I. Bill is consistently the main topic of conversation. However, the contributions of the Army to American higher education are much more complicated than simply the passage of the Servicemen’s Readjustment Act of 1944. A wide variety of programs and efforts championed by the Army during the first half of the twentieth century lack in-depth research and analysis. This study examined the American military transformation from the American …


James Monroe’S White House: The Genius Of Politics And Place, Susan Glen Amos Dec 2022

James Monroe’S White House: The Genius Of Politics And Place, Susan Glen Amos

Doctoral Dissertations and Projects

This research endeavor has discerned the origins of an enduring American nationalistic distinctiveness perpetuated by President James Monroe’s White House. A careful scholarly examination of Monroe’s White House as a cultural landscape enquires into the genesis of interdependence between place and politics. It also studies the depth of the American people’s ability to embrace, as their own, the symbolism and national vision fashioned in these spaces. The juxtaposition of James Monroe’s election as the first United States president after the War of 1812 with the resurrection of the White House manifested for him an exclusive opportunity, still fraught with perils, …

Doctoral Dissertations and Projects

Confederate General James Longstreet watched his dawn attack on Fort Sanders in Knoxville, Tennessee, fail through the frigid morning air on November 29, 1863. Fort Sanders would only be the beginning of Longstreet's personal descent from confidence he would be a perfect independent army commander to an individual mired in depression and regret. For the previous two years of the war, Longstreet’s star was on the rise, and he certainly gained supreme confidence in his abilities to lead the Confederacy to victory. After being separated from his favorite commander, Joseph Johnston, early in the war, Longstreet often thought he had …

The Jewish Basis For The Born Again Experience In John 3, Francis-David Athelstan Scalzo Dec 2022

The Jewish Basis For The Born Again Experience In John 3, Francis-David Athelstan Scalzo

Doctoral Dissertations and Projects

The dissertation’s objective will be to analyze what Nicodemus—as a Pharisee who was knowledgeable of the Hebrew Bible and the prevalent Jewish theology of his period—should have understood, given his position, concerning Jesus’ teaching of being born again. By examining the Old Testament (the TaNaK) and Intertestamental Jewish theology, it will be argued in the dissertation’s six chapters how Nicodemus, as a prominent Pharisaical religious instructor, should have understood the concept of spiritual rebirth as well as the scriptural significance of water and the Spirit, including the guidance and obedience inherent in Jesus’ teaching on the wind. As an introduction …


Using Popular Music To Engage The Multiculturally Diverse Secondary School Band, Todd Waldon Murphy Dec 2022

Using Popular Music To Engage The Multiculturally Diverse Secondary School Band, Todd Waldon Murphy

Doctoral Dissertations and Projects

Despite the increasing acceptance and enthusiasm for multicultural popular music in some high schools in the United States, traditional music teachers are often hesitant to embrace this trend. Even though the United States is responsible for creating many popular music styles, European music education philosophy is ahead with popular music education. Because of the United States' changing demographics, a new strategy must be developed to address this issue and implement it to the band director's advantage. Ethnic diversity and multiculturism have been creative factors in the United States, which explains why American culture has produced a wide variety of musical …

Connecting Diverse Communities Through A 4-H Urban-Rural Experience, Laurie Murrah-Hanson, Brittani Lee, Pamela Bloch

Journal of Extension

Misconceptions regarding agricultural careers are exacerbated by increasing urbanization and are one of many differences in perspective between urban and rural communities. The One Georgia 4-H Urban-Rural Experience addresses this divide through a statewide youth exchange focusing on the agricultural sector. The program includes a multifaceted look at agricultural careers through visits to urban and rural communities. Focus group evaluations revealed the impact on youth through exposure to new careers, increased understanding of the diversity of agriculture, awareness of the interconnected nature of urban and rural communities, and a sense of belonging to a diverse group of youth.


Exploring Public Speaking Self-Efficacy In The 4-H Presentation Program, Nicole Marshall-Wheeler, Yu Meng, Steven Worker Dec 2022

Exploring Public Speaking Self-Efficacy In The 4-H Presentation Program, Nicole Marshall-Wheeler, Yu Meng, Steven Worker

Journal of Extension

Strong communication skills are important in an individual’s personal and professional life; however, research regarding what influences youth’s public speaking self-efficacy is limited. To address this gap, we surveyed youth who participated in a statewide presentation event about their self-efficacy and sources of that self-efficacy. Results show mastery experiences have the greatest relationship to youth’s public speaking confidence. Extension can strengthen youth’s public speaking self-efficacy by increasing the number of presentation opportunities and by removing barriers from participating in existing presentation opportunities.
