Individual Differences In Age And Testosterone Are Uniquely Associated With Neural Oscillatory Activity Serving Verbal Working Memory In Children And Adolescents, Abraham D. Killanin

Theses & Dissertations

During the sensitive period of adolescence, the human brain undergoes dynamic changes in structure and function resulting in vast executive function gains. Verbal working memory (VWM) is one executive function that serves as a foundation to language acquisition, reading, and learning. Many have examined the development of VWM in youth, but few have probed age-related changes in the underlying neural oscillatory dynamics, and none have examined testosterone-related changes. We recorded magnetoencephalography during a modified Sternberg VWM task in 82 youth participants aged 6 – 14 years old and collected salivary testosterone samples. Significant oscillatory responses were identified and imaged using …

Functional Analyses Of Response Chains, Brinea Charles

Theses & Dissertations

Although functional analyses (FAs) have been used to determine the cause of problem behavior and to develop effective treatment (Iwata et al., 1982/1994; Hanley et al., 2003), they may pose an increased risk of injury to the participant and others when the target response is a severe behavior (Smith & Churchill, 2002). Several studies have explored the efficacy of using response class hierarchies (precursors) in an FA, but fewer studies have explored early sub-responses in a behavior chain. Therefore, the purpose of this study was to 1) identify a systematic process for defining response chains of severe behavior and verify …

Development, Validation, And Diagnostic Performance Of A Novel Radiomic Model For Predicting Prostate Cancer Recurrence, Linda M. Huynh

Theses & Dissertations

Multi-parametric magnetic resonance imaging (MP-MRI)-derived radiomics have been shown to capture sub-visual patterns for the quantitative characterization of prostate cancer (PC) phenotypes. The present dissertation seeks to develop, evaluate, and compare the performance of an MRI-derived radiomic model for the prediction of PC recurrence following definitive treatment with radical prostatectomy (RP).

MP-MRI was obtained from 339 patients who had a minimum of 2 years follow-up following RP at three institutions. The prostate was manually delineated as the region of interest and 924 radiomic features were extracted. All features were evaluated for stability via intraclass correlation coefficient (ICC) and image normalization …

Multimodal Investigations For The Identification Of Surgically Relevant Brain Areas, Kevin Tyner

Theses & Dissertations

Epilepsy is a neurological disease leading to recurrent and unpredictable seizures. Patients can be diagnosed as focal onset, where the seizure focus resides in one hemisphere; generalized onset, where seizure foci reside in both hemispheres; or unknown onset. Anti-seizure medications are the first line of treatment, and those whose seizures cannot be controlled with medication are diagnosed with drug-resistant epilepsy (DRE). For patients diagnosed with focal onset epilepsy to achieve seizure freedom, surgical resection of the epileptogenic zone (EZ), the region of the brain that is both necessary and sufficient for initiating seizures, is required. The EZ is a theoretical …

The Interactions Of Centromeric Nucleosomes Elucidated By Atomic Force Microscopy, Shaun Filliaux

Theses & Dissertations

Nucleosomes are the fundamental unit of compaction for DNA in the genome. These positively charged proteins have two main types of nucleosomes: canonical (H3 containing) and centromere (CENP-A containing). The compacting of DNA allows for DNA to fit into the nucleus of cells, but creates a barrier for DNA accessibility for operations such as replication or transcription. Centromeric chromatin is a subset of chromatin structure and governs chromosome segregation. Compared to the bulk chromosome, centromeres are composed of H3 and CENP-A nucleosomes in which H3 histones is replaced by its homolog CENP-A histone. This results in nucleosomes with different structures, …

The Experience Of Home-Based Music Therapists Working With Individuals With Intellectual And Developmental Disabilities: A Thematic Analysis, Sarah Mayr

Theses & Dissertations

According to the Administration for Community Living (ACL), an estimated 7.38 million people in the United States live with an intellectual and/or developmental disability (2021). Many individuals with intellectual and developmental disabilities (I/DDs) reside in community-based settings, such as private residences, family members’ homes, or group homes (ACL, 2021). However, little research exists exploring home-based music therapy (HBMT) for people with I/DD, especially from the clinician’s perspective. Thus, this study examines the experiences of home-based music therapists working with individuals with I/DD to provide a foundational overview. Three music therapists working in home-based settings participated in semi-structured guided interviews, which …

Theses & Dissertations

Using autoethnographic, arts-based, and embodied methods, this postformal dissertation study establishes the first of a two-part research-as-community-building template designed with racially and socioeconomically diverse school communities in mind. Imagined as a double helix in an echo of human DNA, it describes an arts-based, embodied self-study (Helix 1) as a prerequisite for later study of community (Helix 2, not yet complete) typified by mindful engagement across socially constructed lines of difference and attention to the potential building blocks of collaborative leadership across those same lines. As a prerequisite to community work, I explored my lifetime encounters with others of difference (Chang, …

Closing The Gap Between Theory And Practice To Promote Equity In Stem: Coaching Teachers With Udl Strategies To Empower Students, Debbie Langone

Theses & Dissertations

U.S. schools have witnessed educational reforms that have shifted science curriculum and pedagogy within classrooms. Yet, all these reforms have failed to reduce the racial and gender gaps in STEM fields. In 2016, New York State implemented the New York State Science Learning Standards (NYSSLS) to address these gaps. Problems remain, however, with the NYSSLS standards. The NYSSLS do not offer teachers pedagogical practices with regards to implementation. Students are expected to engage in practices as they emulate scientists, without any direction for teachers to support students through these practices, and they exemplify a deficit mindset by placing the blame …

An Investigation Into The Female Correspondents' Experiences In The Media Industry In Kenya, Pili Chizi Chimerah

Theses & Dissertations

Correspondents in the media organizations in Kenya face myriad challenges to remuneration, working conditions, and job security. These challenges have a direct effect on their performance at the workplace. Correspondents play a pivotal role in the success of media organizations, and research shows that they contribute about 80 percent of media content (Devex, 2022). Odhiambo (2002) states that correspondents are paid on retainers and sometimes need reasonable contracts, making them vulnerable. However, female correspondents face double challenges based on their gender. There is a gender bias in newsrooms, with male correspondents dominating (Selva & Andi, 2020).

Media's Coverage Of Biotechnology And Gmo’S: How Kenyan Broadcast Media Covered The Lifting Of The Ban On Genetically Modified Foods., Zeynab Nyangule Wandati

Theses & Dissertations

The introduction of genetically modified organisms (GMOs) has been controversial globally, with differing views on the risks and benefits of their use in agriculture, even though the technology is extensively used in medicine. In Africa, the adoption of GMOs has been relatively slow compared to other regions due to a combination of factors, including poor infrastructure, inadequate resources, and public resistance. Studies have shown that the media often portrays GMOs as a threat to human health and the environment, a narrative often pushed by the news sources interviewed, with little emphasis on their potential benefits or the science of it. …
