Advancing Karl Jaspers: The Connection Between The Theory Of Existential Communication And Mentoring Satisfaction, Nolan Patrick Bowers

Electronic Theses and Dissertations

Existential philosopher Karl Jaspers’s theory (1932/1970; 1935/1971b) of existential communication is understood to be his most important contribution to existentialism. Additionally, this theory has unique ties to the phenomena of communication, begging its use as a dialogic theory. However, Jaspers’s theory has been relatively untouched by academia. This thesis understands the theory of existential communication through an operationalization of its aspects and explicitly connecting them to communicative behaviors. These aspects of existential communication are (1) vulnerability, (2) open-mindedness, and (3) equality. This study set out to determine whether these aspects could be found within mentoring relationships and support the aspects …

Lidar Remote Sensing And The Monitoring Of Brazilian Amazon Forest Structure: Tackling Issues And Finding New Possibilities, Pedro Valle De Carvalho E Oliveira

Electronic Theses and Dissertations

The Amazon is the largest tropical forest in the world and around 60% of it is in Brazil. The amount of carbon stored in the region uncertain, the impacts of land use and climate changes are unknown, and what drives the dynamic of the forest structure is still under a heated debate. Optical remote sensing has been used for a long time to assist the monitoring of the Brazilian Amazon. However, optical remote sensing only allows a comprehensive study from the top of the forest canopy. In contrast, lidar remote sensing of forests can produce robust information regarding the canopy …

Increasing Retention Of Women In Hunting And Fishing, Shelby Isensee

Electronic Theses and Dissertations

Despite national declines in hunting and fishing, women are making inroads in historically male-dominated sports. To further encourage women’s participation, states established programs to recruit, retain, and reactivate [R3] hunters and anglers. Women are participating in these programs and other recreational groups to access opportunities to learn skills and grow their networks. Yet, very little is known about what programs are offered for women, what aspects of programs are most effective to support women’s retention in these activities, and what women’s hunting and fishing groups are available across the landscape. To address these questions, I collected qualitative data from participant …

The Impact Of Sitting And Crawling On The Acquisition Of Object Permanence In Infants With Motor Delays And Infants With Typical Development, Karl Jancart

Electronic Theses and Dissertations

Object permanence (OP) is the ability to understand that objects continue to exist even when they cannot be perceived. During play, infants with an understanding of OP will continue searching for toys when the toys have been obscured by other items. Searching requires movement. The theory of embodied cognition maintains that the form and function of an organism’s body influence how the organism learns; Therefore, if a child has difficulties with movement, as demonstrated by children with motor delays, they will likely have difficulty engaging in play, the modality by which children learn about their world. The current research is …

Using A Three-Dimensional Theoretical Orientation Matching Model To Predict Therapeutic Outcomes, Daniel Rhodes

Electronic Theses and Dissertations

Matching helpers and clients in a therapeutic setting is inefficient and ineffective. So far, there are no significant and enduring variables that reliably match helpers and clients that lead to positive therapeutic outcomes. This study attempts to match helper and client using theoretical orientation. It uses a quantitative methodology to predict therapeutic outcomes given match quality in the therapeutic dyad. Participants were 30 dyadic pairs—consisting of one helper and one client—who had a pre-existing therapeutic relationship. Each was given an assessment tool, used to measure their theoretical orientation to psychotherapy. Results showed no statistically significant relationships between theoretical orientation match …

Negative Psychology Of Anti-Semitism: Fear Of The Uncategorizable, Benjamin Strosberg

Electronic Theses and Dissertations

Anti-Semitism is a pervasive global issue, particularly prominent in the United States. Studying and defining anti-Semitism prove remarkably challenging for scholars, leading to inadequate understanding and exclusion from contemporary academic discourse and social justice initiatives. In this dissertation, I made the case that anti-Semitism is hard to categorize, stemming, in part, from the difficulty in categorizing what it is to be Jewish, which seems to be multi-form (a figure of thought, a race, an ethnicity, a religion, a nation, none of the above). In thinking about the difficulty in categorization, I constellated various instances of anti-Jewish practices across historical epochs …

The Normative Requirement For Shared Decision Making (Sdm) In Healthcare Ethics, Margaret Nornor-Quadjie

Electronic Theses and Dissertations

Medicine and medical technology started to advance after World War II. During that period, the practice of medicine became technical. A lot began to happen in the biomedical world during the period after WWII that attracted comments, criticisms, and analyses from scholars. Perhaps, the 1947 Doctors’ Trial at the Nuremberg Tribunal and the Nuremberg Code may be said to be the defining moment for bioethics. These events eventually led to, in the United States, the passage of the National Research Act of 1974 that established the Institutional Review Board system and the National Commission for Protection of Human Subjects of …

Comparative Functional And Genomic Analysis Of Protein Targets Of Sexual Selection In Primates, Brianna Ports

Electronic Theses and Dissertations

Sexual selection is driven by the differential reproductive success of individuals, which is influenced by competition for mates and mate choice. In primates, this selective pressure has been attributed to the development of distinct anatomical, physiological, and behavioral characteristics. By employing comparative functional and genomic methodologies, this study aimed to assess the repercussions of primate sexual selection. To better understand the mechanisms driving sexually selected traits, an unbiased genome-wide analysis was used to associate rates of protein evolution with relative testes size and sexual size dimorphism. While previous research focused on the rapid evolution of male reproductive proteins in response …

Environmental Exposures And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

In recent years, research into air pollution has shown that exposure to certain components in air pollution, primarily PM2.5 can accelerate biological aging and thereby lead to increased susceptibility to multiple diseases. We hypothesize that prolonged exposure to air pollutants can result in premature aging leading to extensive tissue dysfunction and susceptibility to diseases. To examine this, we exposed mice to PM2.5 for 9, 15, and 21 days, then measured the telomere lengths, cellular senescence, and histone methylation patterns of multiple cell types. We found consistently increased telomere attrition, cellular senescence and advanced age-consistent histone methylation patterns in groups exposed …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

Communicating In Crisis: Rhetorical (De)Stabilization During The Covid-19 Pandemic., Brittany Nicole Smart

Electronic Theses and Dissertations

This project explores the role of rhetoric in crisis—how rhetoric can contribute to both the stabilization and destabilization of a worldwide health emergency. Specifically, I utilize the COVID-19 pandemic as a case study to investigate how institutional rhetorics exacerbated the ongoing burnout epidemic amongst healthcare workers. Through a feminist, materialist take on institutional ethnography (Fullagar & Pavlidis, 2021; Griffith & Smith, 2014), I show how, while institutions like the CDC were under pressure to contain the spread of the virus, in the chaos of communicating safety regulations to healthcare professionals, they inadvertently subverted clinician autonomy and expertise by “coordinating” (LaFrance, …

Automated Usability Evaluation Utilizing Log Files And Data Mining Techniques., Sima Shafaei

Electronic Theses and Dissertations

Usability evaluation is one of the essential aspects of software production. This evaluation should be done during the entire life cycle of a software application, from pre-production to production and post-production. However, the collection and evaluation of usability data can be a very challenging, time-consuming, and expensive task to be conducted manually, particularly for certain types of products and working conditions. These challenges may include the need to recruit participants fully engage and motivate them during evaluation, and factor in environmental conditions. Other challenges may include collecting data in real-world environments, especially when the users are geographically dispersed, minimizing evaluator …

“I Became Myself”: Exploring Cultural Learning Through Stories And Storytelling., Leah Halliday-Johnson

Electronic Theses and Dissertations

Despite broad acknowledgement in education that culturally responsive teaching is essential to meeting learners’ needs, defining and operationalizing culturally responsive teaching remains a challenge. Along with being designed to meet the needs of students from diverse racial and cultural backgrounds who have traditionally been underserved, one commonly identified feature of culturally responsive teaching is building on students’ cultural assets to promote their learning. And while stories and storytelling are among the most common teaching tools, storytelling pedagogies tend to use stories to deliver content or to assess student learning. This dissertation explores collaborative story sharing as an approach to helping …
