Synthesis Of Bismuth Ferrite For Photoelectrochemical Water Splitting, Fagr Albagle

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent decades, researchers have noted a significant academic gap between males and females. Boys are falling behind their female counterparts. Boys have lower grades and are less likely to participate in more advanced coursework. Boys are more likely to drop out of high school and college, and are graduating from higher education in lower numbers than females. Several reasons are given for the gender achievement gap in K-12 education, including the higher percentage of female teachers, the increase of a literacy focus, and the lack of experiential learning in school. In an effort to bridge the gender achievement gap, …

Evaluation Of Sigma Ligand Az66 Analgesic Potentiation Of Cannabinoids, Jacqueline Morris

Honors Theses

Sigma receptors have become a popular subject for research the past few decades, but there is still much mystery behind these receptors and how they work. Sigma receptors, like cannabinoid-1 (CB1) receptors, have effects on the human body including appetite regulation, depression, and analgesia. AZ66 is a highly selective sigma receptor ligand that has antagonistic properties. Sigma receptor antagonists have been shown to potentiate the analgesic effects of opiates; however, there are no known literature reports about the interaction between the sigma receptor system and the endocannabinoid system, including CB1 receptors. The purpose of this study is to evaluate AZ66 …

Cannabidiol Mitigates Opioid Reward On Conditioned Place Preference In Mice, James Roland Markos

Honors Theses

This study sought to determine whether the cannabis constituent, cannabidiol (CBD), is able to attenuate morphine reward in the conditioned place preference (CPP) paradigm. Mice received IP injections of either saline or morphine and increasing doses of CBD that were paired with a distinct environment in the CPP apparatus. Morphine-produced place preference was dose-dependently blocked by CBD. Furthermore, none of the tested doses of CBD exhibited reward or aversion. The finding that CBD blocks opioid reward suggests CBD may be useful as an abuse deterrent, particularly in the setting of opioid use for pain management.

Hinge Sequence Elements In Epithelial Cadherin Form And Function, Jessica Elizabeth Barnett

Honors Theses

Cadherins play the vital role of mediating cell-cell adhesion in properly functioning tissues of the human body. Malfunction of these adherent cells can lead to drastic consequences like cancer metastasis. Thus, it is imperative to ensure the functionality of the molecular mechanism that drives these adhesive interactions. Of the various types, our studies specifically focused on the structure and function of the 'hinge region' in epithelial cadherin. This 'hinge region', composed of amino acid residues C9, P10, and E11, was of particular interest because it is the site of strand-swapped dimerization. The residues P10 and E11 are conserved within the …

Egg Laying Bird With Male Plumage Demonstrates The Puzzling Nature Of Sexual Differentiation And Selective Mate Preferences In Zebra Finches, John Aaron Howell

Honors Theses

Zebra finches (Taeniopygia guttata) are oscine Passerine songbirds that are native to Australia. Zebra finches have sexually dimorphic plumage, song nuclei, and behavior. The role of chromosomes, hormones, and genes on sexual differentiation are not completely understood. A gynandromorph in our aviary had male plumage, a male partner, and produced viable offspring. Mate preference tests revealed lower preference for the gynandromorph and its progeny than controls, suggesting that they had some traits that made them unattractive to other birds. Gynandromorph lineage males had greater same-sex preferences than control males. Chromosomes in birds are different than those in humans. Males are …

A Raman Spectroscopic And Computational Study On The Effects Of Electron Withdrawing Groups On Halogen Bonding, Katelyn Allen

Honors Theses

Here, the effects of individual electron withdrawing groups on halogen bond strength are investigated using Raman spectroscopy and electronic structure calculations. Halogen bonding is a unique and relatively unexplored noncovalent interaction that has recently garnered considerable attention due to its applications in materials development. When a halogen, such as chlorine, bromine, or iodine, accepts electron density from a Lewis base such as the nitrogen of pyridine a halogen bond arises. The anisotropic distribution of electron density about a covalently bound halogen, also known as the σ-hole, plays a significant role in halogen bond formation. The magnitude of the electropositive region …

Population Genetics Of The Giant Red Centipede Along The Appalachian Mountains, Kayla Elayne Ladner

Honors Theses

This study focused on population genetics of the giant red centipede, Scolopocryptops sexpinousus, in the Southern Appalachian Mountains. Two genetic markers were used—the mitochondrial COI gene, and the nuclear RNA Polymerase II gene. The goal of this study was to determine how many genetically distinct populations of this invertebrate species exist within the study area, and to understand the spatial distribution of genetic diversity within and among populations. I hypothesized several genetically distinct populations of S. sexpinosus would be detected because the complex topographic characteristics and historical climate cycles of the region are thought to limit movement of many forest …

Bring Your Own Device Initiative To Improve Engagement And Performance In Human Anatomy And Physiology I And Ii Laboratories, Kelsey Hillhouse

Honors Theses

At the University of Mississippi, just 4.93% (2014) and 6% (2015) of Human Anatomy and Physiology students responding to an informal, opinion survey stated that their favorite lab activity was using microscopes. In addition, performance on lab practical questions involving the identification of specimens under a microscope is low with the average percent correct being as low as 31.85% and no higher than 41.94%. These numbers are troubling in that Human Anatomy and Physiology I and II are required courses for students desiring entry into many allied health professions where knowledge of tissues, obtaining samples for biopsy, and interpreting microscopic …

Sex And The Law Of Ancient Athens, Laura S. Dona

Honors Theses

This paper will explore the legal implications of social norms and taboos surrounding both biological sex distinctions and sexuality in Ancient Athens. I believe that the legal speeches used in Ancient Athenian court cases reflect a unique gateway into understand these social norms, because these speeches are arguments made in an attempt to appeal to a jury of Athenian citizens. From these arguments, we can infer what would likely be honorable versus condemnable, and from the logical structure of the arguments we can further understand their legal reasoning. From what I have researched on biological sex and sexuality norms of …

A Study Of The Hydrophobic Interactions Between Twenty-Three Cb1 Selective Jwh Compounds And An Active-State Cb1 Receptor Model To Discover Key Structural Features Of The Jwh Compounds And Key Protein Residues Of The Cb1 Receptor, Lyncyn Louise Reliquias

Honors Theses

Synthetic cannabinoids, commonly found in Spice, have recently become a popular substitute for marijuana as they have similar effects to THC, the most powerful constituent of marijuana. Additionally, they are increasingly becoming a source of drug abuse as they cannot be detected with normal drug test screenings. This study specifically analyzed a total of twenty-three CB1 selective JWH compounds and their hydrophobic interactions with an active-state CB1 receptor model. The ligands were categorized per their structural similarities, and this study was aimed to find patterns within each structural moiety that would lead to the discovery of key structural features and/or …

Action Understanding Via Mirror Neuron Systems: A Proposed Model For The Science And Treatment Of Stuttering, Madison Jones

Honors Theses

Persistent developmental stuttering is generally considered to be a speech disorder characterized by repetitions, prolongations and postural fixations, and is relatively resistant to therapy. While mainstream stuttering therapy continues to rely on behavioral speech targets, recent research suggests that mirror neuron systems can be activated to temporarily induce natural sounding fluent speech in those who stutter via exposure to second speech signals. Despite the prevalence of speech-motor based stuttering treatments, a unified account of how and why fluency is enhanced through endogenous methods remains elusive. The purpose of these two exploratory studies is to further test the validity of the …

Little Philosophers: Assessing And Prompting Philosophical Reasoning With Children, Makensey Sanders

Honors Theses

There is a debate in academic philosophy and psychology of whether or not children can or should do philosophy. Robert Kitchener asserts that due to cognitive limitations, children under the age of 10 cannot think philosophically (Kitchener, 1990). Murris (2000) challenges Kitchener's arguments and concludes that more research is needed. Further, this is a period during which children show individual differences and development in cognitive capacity, specifically within executive function relating to conscious control that may influence abstract thought (Zelazo et al., 1997). The present study assessed 7- to 9-year-olds' and adults' ability to answer philosophical questions in relation to …

Synthesis And Biological Evaluation Of Cannabinoid Receptor Ligands, Mariah Leigh Cole

Honors Theses

The cannabinoid receptors, members of the G-protein coupled receptor (GPCR) superfamily, have been implicated in numerous human physiological functions and diseases. These receptors, cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2), are most concentrated in the central nervous system and immune cells, respectively, and have each become a target of therapeutic interest. Dual CB1/CB2 agonists such as delta-9-tetrahydrocannbinol (THC) have demonstrated efficacy in the treatment of nausea, pain, and glaucoma, but suffer from psychotropic effects mediated by CB1, motivating the search for CB2 selective therapeutic agents. Selective modulation of the CB2 receptor has therapeutic potential in human health disorders …

The purpose of this nonexperimental project study was to measure relationships among factors influencing degree of implementation of technology (ITC) in the classroom using Dewey's experiential theory with an emphasis upon constructivism as a theoretical framework. A modified survey, Technology and Professional Development Survey of Georgia High School Teachers, was distributed to …

Motivations To Return To A Gang After Severe Physical Victimization, Nora Vlaszof

Walden Dissertations and Doctoral Studies

Abstract

Gang violence is a social concern because of the risks of victimization among gang members and their communities. Many gang members have been victims of gang violence, and some choose to remain involved with their gang even after being victimized. Researchers have explored why people join gangs, but less is known regarding the gang-victimization link, which is the focus of this study. Social bond theory guided the study's research question on the motivation of gang members to rejoin their gang after severe physical victimization. A multiple case study design was employed with a purposeful sample of six English-speaking men, …

School of Earth, Environmental, & Marine Sciences Faculty Publications

Today the biggest incentive to attempt the restoration and protection of estuarine systems is their widely recognized ecological and economic importance. In the reconstruction of an estuary where the original aquatic communities disappeared before the restoration interventions, the fish assemblage is an adequate source of indicators of initial recovery. Following substantial restoration efforts, this study reports on the biannual for a lustrum monitoring and assessment of a severely degraded estuary (Garrapatas) in terms of its fish assemblage using a reference estuary (Barberena) in Tamaulipas, Mexico. Twenty fishes were associated with the restoring and reference estuaries. Species composition (richness, abundance, dominance) …

Impact Of The Capillary Pressure-Saturation Pore-Size Distribution Parameter On Geological Carbon Sequestration Estimates, Chu-Lin Cheng, Edmund Perfect, T. Edward Yu, Michael J. Gragg

School of Earth, Environmental, & Marine Sciences Faculty Publications

Cost estimates for geologic carbon sequestration (GCS) are vital for policy and decision makers evaluating carbon capture and storage strategies. Numerical models are often used in feasibility studies for the different stages of carbon injection and redistribution. Knowledge of the capillary pressure-saturation function for a selected storage rock unit is essential in applications used for simulating multiphase fluid flow and transport. However, the parameters describing these functions (e.g. the van Genuchten m pore size distribution parameter) are often not measured or neglected compared to other physical properties such as porosity and intrinsic permeability. In addition, the use of average …
