The Efficacy Of Leadership Training: A Case Study Of The Sullivan Foundation's Inspired Leadership Workshop, Rachel Berry

Honors Theses

All too often, leaders are raised up without the proper training for the job. Although a variety of different leadership training methods have been implemented over the last few decades, the efficacy of these training methods are still in question. Therefore, this thesis serves to examine the efficacy of leadership training programs by examining a leadership workshop, conducted by the Sullivan Foundation on two separate occasions, in order to understand if leadership training improves one’s leadership ability. In order to measure the efficacy of the Sullivan Foundation’s Leadership workshop, this thesis utilized a case study approach to examine the workshop …

Transcriptomic Changes And The Roles Of Cannabinoid Receptors And Pparγin Developmental Toxicities Following Exposure To Δ9-Tetrahydrocannabinol And Cannabidiol, Zacharias Pandelides, Neelakanteswar Aluru, Cammi Thornton, Haley E. Watts

Faculty and Student Publications

Human consumption of cannabinoid-containing products during early life or pregnancy is rising. However, information about the molecular mechanisms involved in early life stage Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) toxicities is critically lacking. Here, larval zebrafish (Danio rerio) were used to measure THC- and CBD-mediated changes on transcriptome and the roles of cannabinoid receptors (Cnr) 1 and 2 and peroxisome proliferator activator receptor γ(PPARγ) in developmental toxicities. Transcriptomic profiling of 96-h postfertilization (hpf) cnr+/+ embryos exposed (6 - 96 hpf) to 4 μM THC or 0.5 μM CBD showed differential expression of 904 and 1095 genes for THC and CBD, respectively, …

A City Divided: A Gis-Informed Study Of Urban Planning In Amman, Jordan, Ella Lawson

Honors Theses

Amman, the capital of Jordan, faces an impending infrastructure crisis. The city is plagued by water shortages, a lack of affordable housing, extreme traffic congestion, and dwindling open space. Over the past seventy-five years, several urban planning commissions have attempted to address these issues through policy change and other municipal directives. These plans help illustrate the different forces at play in constructing the city—whether they be the residents themselves, city officials, or international consultants. All the plans use neighborhoods as a primary metric for measuring need and organizing development. Likewise, all the plans focus on the importance of green and …

The Role Of Cannabinoid Receptor 2 In Zebrafish Toxicities Following Developmental Exposure To Thc Or Cbd, Haley Watts

Honors Theses

As the laws concerning the regulation of Cannabis Sativa change across the globe, maternal use of cannabinoid-containing products during pregnancy is a greater concern than ever before. Little research has been conducted on the consequences of maternal use and developmental exposure to ∆9-tetrahydrocannabinol (THC) and cannabidiol (CBD. In this study, larval zebrafish (Danio rerio) were used to measure CBD and THC-mediated adverse outcomes including effects on larval length, eye area, and behavior in the cnr^+/+ and cnr2^-/- zebrafish strains where we discovered that cannabinoid exposure results in a decrease in each of these endpoints. Adult …

Evaluation Of The Bax-Vdac Interaction And Their Influence On Apoptosis In Drosophila Melanogaster, Frances Marie Gatlin

Honors Theses

Apoptosis, also known as programmed cell death, is a cellular process used for development or for when cells undergo injury or stress. The Bcl2 family of proteins includes both pro-apoptotic and anti-apoptotic proteins that control the intrinsic pathway of apoptosis. Understanding the mechanisms and influence these proteins have on apoptosis is an important area of research focused on in Dr. Jones’s lab. Evidence shows a homology amongst the Bcl2 family of proteins at the BH3 domain. Dr. Jekabsons' lab has found a potential homology amongst VDAC 1-3 and the Bcl2 family at the BH3 domain.

Specifically, our lab is using …

Elucidating The Functional Location Of Platelet-Derived Growth Factor Receptor Alpha, Creation Of A Review Chapter On The Use Of Zebrafish In Studying Congenital Heart Defects, And Using 3d Printing To Create Laboratory Tools, Jaret Lieberth

Honors Theses

Congenital heart defects (CHDs) are currently the most prevalent form of birth defect in the United States. Their combined frequency and severity make necessary a deeper understanding of the molecular underpinnings guiding heart formation. The first major step in cardiac morphogenesis, cardiac fusion, involves the medial movement of bilateral populations of myocardial precursor cells to the embryonic midline, where they merge to form the primitive heart tube. Although crucial to subsequent organogenesis, the precise mechanisms governing cardiac fusion remain unknown. Previous studies have found that a mutation in platelet-derived growth factor receptor alpha (pdgfra), called refuse-to-fuse (ref), results …

Impacts Of Embryonic Exposure To Cannabidiol Or ∆9-Tetrahydrocannabinol On Zebrafish (Danio Rerio) Frailty In F0 And F1 Generations, Anika Faruque

Honors Theses

Exposure to cannabinoids during critical development periods has increased with epileptic children being commonly prescribed CBD for seizures and pregnant women taking it recreationally. Many studies have been done on the possible benefits and drawbacks of cannabinoid exposure on the human brain, but not much is known about how it can affect the developing brain long-term. To see the potential adverse effects of cannabinoid exposure during critical stages of development and discover potential developmental origins of disease in consuming cannabinoids during embryogenesis, zebrafish embryos (6-96 hours post fertilization) were exposed to varying concentrations of CBD (0.02, 0.1, 0.5 µM), THC …

The Association Of Handgrip Strength And Mortality: What Does It Tell Us And What Can We Do With It?, Samuel L. Buckner, Scott J. Dankel, Zachary W. Bell, Takashi Abe, Jeremy P. Loenneke

Faculty and Student Publications

© Copyright 2019, Mary Ann Liebert, Inc., publishers 2019. The relationship between grip strength and mortality is often used to underscore the importance of resistance exercise in physical activity guidelines. However, grip strength does not appear to appreciably change following traditional resistance training. Thus, grip strength could be considered reflective of strength independent of resistance exercise. If true, grip strength is not necessarily informing us of the importance of resistance exercise as an adult, but potentially highlighting inherent differences between individuals who are stronger at "baseline" compared to their weaker counterpart. The purpose of this article is to discuss: (1) …

Analysis Of Brevundimonas Subvibrioides Developmental Signaling Systems Reveals Inconsistencies Between Phenotypes And C-Di-Gmp Levels, Lauryn Sperling, Milagros D. Mulero Alegría, Volkhard Kaever, Patrick D. Curtis

Faculty and Student Publications

© 2019 American Society for Microbiology. All Rights Reserved. The DivJ-DivK-PleC signaling system of Caulobacter crescentus is a signaling network that regulates polar development and the cell cycle. This system is conserved in related bacteria, including the sister genus Brevundimonas. Previous studies had shown unexpected phenotypic differences between the C. crescentus divK mutant and the analogous mutant of Brevundimonas subvibrioides, but further characterization was not performed. Here, phenotypic assays analyzing motility, adhesion, and pilus production (the latter characterized by a newly discovered bacteriophage) revealed that divJ and pleC mutants have phenotypes mostly similar to their C. crescentus homologs, but divK …

Analysis Of Brevundimonas Subvibrioides Developmental Signaling Systems Reveals Unexpected Differences Between Phenotypes And C-Di-Gmp Levels, Lauryn Anne Sperling

Electronic Theses and Dissertations

The DivJ-DivK-PleC signaling system of Caulobacter crescentus is a signaling network that regulates polar development and the cell cycle. This system is conserved in closely related bacteria, including the sister genus Brevundimonas. Previous studies had shown unexpected phenotypic differences between the C. crescentus divK mutant and the analogous mutant of Brevundimonas subvibrioides, but further characterization was not performed. Here, phenotypic assays analyzing motility, adhesion, and pilus production (the latter characterized by a newly discovered bacteriophage) revealed that divJ and pleC mutants have mostly similar phenotypes as their C. crescentus homologs, but divK mutants maintain largely opposite phenotypes than …

Characterizing The Developmental And Reproductive Toxicities Of Cannabidiol And Δ9-Tetrahydrocannabinol, Dennis Ray Carty

Electronic Theses and Dissertations

Medical marijuana is legal in twenty-nine of the United States and an additional nineteen states have passed legislation for cannabidiol (CBD) treatment of drug-resistant epilepsy, such as Dravet Syndrome (DS) which is diagnosed in children as young as two months. While CBD has shown anecdotal and recently clinical trial efficacy in reducing seizure frequency in DS patients, little is known about the potential adverse side-effects on child physiology, brain development, adult disease, or subsequent generations. Moreover, CBD is rarely administered without including low concentrations of Δ9-tetrahydrocannabinol (THC). The goal of this project is to characterize the relative morphological, behavioral, reproductive, …

Effects Of Benzo[A]Pyrene And Cyp19a1b Knockdown On Zebrafish Development, Khalid M. Alharthy

Electronic Theses and Dissertations

Benzo[a]pyrene (BaP) is a ubiquitous environmental contaminant that is both an endocrine disruptor and a carcinogen. Aromatase (CYP19) is a key enzyme in steroidogenesis playing a key role in the hypothalamus-pituitary-gonad feedback loop. We hypothesized that BaP would negatively impact cyp19a1b expression in zebrafish, in turn, adversely affecting development and physiology. Here, we consider whether the toxicities observed following BaP exposure are comparable to those following a transient morpholino (MO)-mediated CYP19a1b knockdown or exposure to an aromatase inhibitor (fadrozole) during early development. One-cell zebrafish embryos were injected with a CYP19a1b-MO or control-MO. Other non-injected embryos were exposed to nominal waterborne …

The Art Of Going Beyond In Hossana, Ethiopia, Megan Elizabeth Flowers

Electronic Theses and Dissertations

In this study, I examine what education as development means for the men and women who live in Hossana town, Ethiopia. The ethnographic focus of this study is on understanding how education as development evokes different meanings for socio-political participation by rural students at a teacher training college and townspeople respectively. I discuss these conceptual differentiations in relation to the changes in beliefs and strategies that have occurred in Hossana and greater Ethiopia elsewhere over the course of several decades of local and global changes in the social order. I use the emic category of yilhunnta, as the social recognition …

Exploration Of The Balanced Scorecard As A Tool For Performance Measurement And Strategic Planning In Higher Education Development, Clifton Perry Moulds

Electronic Theses and Dissertations

This study sought to uncover information about the types of measurement and strategic planning models being used in higher education development, determine what measures are most important and effective for successful development practices, and explore the potential application of the Balanced Scorecard to higher education development operations. Survey data indicated a wide range of quantifiable metrics currently in use and opinions about measurements such as face-to-face visits, delivery of solicitations, and dollars raised. Personal interactions were considered the most important form of measurement, with financial outcomes falling closely behind. Very few survey respondents reported personal knowledge of the Balanced Scorecard, …

Epigenetic Effects Of Benzo(A)Pyrene In Fundulus Heteroclitus And Danio Rerio, Xiefan Fang

Electronic Theses and Dissertations

DNA methylation is one of the epigenetic mechanisms that controls gene expression and is vulnerable to early life environmental toxicant exposures. Our goal was to use two fish models, Fundulus heteroclitus and Danio rerio (zebrafish), to study the benzo(a)pyrene (BaP) effects on DNA methylation status and whether the alterations could contribute to BaP-mediated reproductive and developmental toxicities. Initially, we used Fundulus to study BaP effects on glycine N-methyltransferase (GNMT) expression throughout development. Fundulus embryos were exposed to waterborne BaP at nominally 10 or 100 μg/L and both GNMT mRNA expression and enzyme activity were measured. Quantitative PCR and whole mount …
