Negative Memory Bias And The Impact Of Early Childhood Stress, Elizabeth Cecile Shmikler

Dissertations

Childhood Trauma is a pervasive problem in the United States, and research suggests it serves as a strong contributor and. Predictor for a multitude of negative mental and physical health disorders (Vrijsen et al., 2018). Negative memory bias, a neuropsychological precursor to later onset of adult mental health disorders, has been scientifically related to childhood trauma (Pollak et al., 1998). Despite numerous findings supporting the relationship between negative memory bias, childhood trauma, and mental health, little is known regarding the age of onset of negative memory bias (Brainerd & Reyna, 2012; Kujawa et al., 2011). Given the research supporting the …

The Experiences Of Beginning Counselor Education And Supervision Faculty In The Supervision-Of-Supervision Relationship, Bonnie Jean Nicholson

Heterogeneity Estimators In Random-Effects Meta-Analysis In Education, Qian Wang

Dissertations

Over the last four decades, meta-analysis has proven to be a vital analysis strategy in educational research for synthesizing research findings from different studies. When synthesizing studies in a meta-analysis, it is common to assume that the true underlying effect varies from study to study, as studies will differ in design, participants, interventions, or sample size that can lead to heterogeneity in their underlying effects. The magnitude of this heterogeneity between studies can be quantified as τ2 in a random-effects meta-analysis. Estimating the between-study heterogeneity (τ2) becomes an important part of random effects meta-analysis reporting, since this quantity plays a …

Instance Segmentation-Based Depth Completion Using Sensor Fusion And Adaptive Clustering For Autonomous Vehicle Perception, Mohammad Z. El-Yabroudi

Depth sensing is critical for safe and accurate maneuvering in robotics and self-driving car (SDC) applications. Most recent LiDAR sensors, such as Ouster and Velodyne, offer 360 degrees of scanning at the rate of ten frames per second, making them very appropriate for autonomous driving applications. However, LiDAR point cloud data show many shortcomings, especially its data sparsity and unassigned nature, making it very challenging to utilize in applications such as perception, 3D object detection, 3D scene reconstruction, and simultaneous localization and mapping.

In this study, a novel framework using instance image segmentation and the raw LiDAR data for the …

A Framework For Assessing The 4th Rank Dispersivity Tensor Under Anisotropic Axial Symmetries, Xiang Fan

Dissertations

Multi-dimensional expansion of the advection-dispersion equation necessitated the representation of dispersivity as a 4th rank tensor. This tensorial form of dispersivity has 81 terms in three-dimensions with a maximum of 36 independent terms that may be used to describe Fickian spreading of a dissolved contaminant plume according to intrinsic properties of a porous medium. The complexity of the 4th rank tensor has led to the common practice of simplifying the tensor to only 2 or 3 independent terms by assuming isotropic conditions, although isotropic porous media are uncommon in nature as many natural geologic systems exhibit pronounced anisotropy. A broad …

Exploring Formative Versus Summative Assessment Models On Creative Mindset Development, Dylan Patrick James Kriescher

Dissertations

The purpose of the current research was to explore how the repeated presentation of process-oriented feedback from multiple task attempts can help develop students’ growth mindset. A standard model of assessment practices often involves a one-time summative assessment at the end of a learning period. An alternative model involves the use of formative assessments as intermittent process-oriented feedback throughout a learning period. The use of formative assessment feedback may demonstrate growth to students, while this opportunity is not offered by the summative assessment model. Using elements of formative assessment and guided by Dweck’s (2006) conceptualization of growth mindset, this study …

“Ici On Chante En Français”: Giving A Voice To Cajun Culture, Tessa Espinosa

Dissertations

“Ici on parle Français” (“French is spoken here”) is a popular adage in South Louisiana and can be seen on signage and T-shirts in mom-and-pop stores throughout the heart of Cajun territory. This phrase reflects cultural pride and tenacity in a small but hearty group of people whose identity was nearly stripped away. Musical settings of Cajun French verse constituted a vital part of this culture. Why is this music important? It exists as historical preservation, a means to explore roots in a time when so many are rootless. These songs have been passed down through oral history for generations. …

Animal-Assisted Interventions In Supervision: A Collective Case Study, Connie Elizabeth Couch

Dissertations

Animal-assisted interventions (AAIs) have been discussed in recent conceptual literature as having potential for positive implications when applied in supervision (Chandler, 2017; Jackson, 2020; Owenby, 2017; Stewart et al., 2015). However, there was limited empirical foundation or guidance for the integration of two distinct specializations (AAIs and supervision). The purpose of this qualitative collective case study (Stake, 2006) was to explore and understand the experiences of supervisors who have been implementing AAIs within the context of supervision. Specifically, this study addressed the following overarching research question and two sub-questions were addressed: Q1 Why are supervisors integrating AAIs into supervision? Q1a …

Preclinical Behavioral Assessments Of Mitraginyne, The Main Psychoactive Alkaloid In Kratom, Rachel Burroughs

Dissertations

Mitragyna speciosa (kratom) is a medicinal plant indigenous to Southeast Asia and Africa with a long history of use for a variety of ailments, including diarrhea, pain relief, cough suppression, and amelioration of opiate withdrawal symptoms. Despite its status as an herbal remedy, kratom is banned in some countries due to a myriad of negative health risks. Preclinical psychopharmacology studies of mitragynine (MG), the main alkaloid of kratom, indicate it has opioid-like effects at higher doses and psychostimulant-like effects at lower doses. The current study utilized three rodent behavioral paradigms to evaluate the putative psychostimulant effects of MG. The specific …
