Asian Jumping Worm (Megascolecidae) Impacts On Physical And Biological Characteristics Of Turfgrass Ecosystems, Ella L. Maddi Jan 2019

Asian Jumping Worm (Megascolecidae) Impacts On Physical And Biological Characteristics Of Turfgrass Ecosystems, Ella L. Maddi

Honors Theses

Asian Jumping worms (Megascolecid spp) were introduced to North America in the early 1900s and have been altering soils in forest ecosystems as they spread throughout the continent. The worms differ from other introduced earthworms in their ability to consume large densities of organic material and potentially alter nutrient cycling in the ecosystems that they invade (Greiner et al. 2012). This study examined if and how Asian jumping worms alter turfgrass systems by changing the biological or physical properties of soil. To do this we conducted a mesocosm experiment and observational field study. For the mesocosm study we inoculated boxes …


A Rethinking Of Gray Asexuality: What Do We Learn From An Undefinable Identity?, Jason M. Gurevitch Jan 2019

A Rethinking Of Gray Asexuality: What Do We Learn From An Undefinable Identity?, Jason M. Gurevitch

Honors Theses

Gray-Asexuality offers us a paradox in understanding sexuality, since while it is posed as a middle ground between Asexual and Allosexual, it is also solidly a category of Asexuality. This poses the question of when does someone become Asexual and if they are ever interested in sex why are they not just Allosexual? While understandings of Asexuality that have excluded the Gray-Asexuality can ignore this question, including it requires asking this question, which not only requires defining Asexuality, but also more importantly requires a naming of what normative sexuality is. Within these contexts people who are Gray-Asexual engage in a …


African Savannah Elephant Group Size And Behavior In The Makgadikgadi Pans National Park, Botswana, Katherine S. King Jan 2019

African Savannah Elephant Group Size And Behavior In The Makgadikgadi Pans National Park, Botswana, Katherine S. King

Honors Theses

African savannah elephants (Loxodonta africana), the largest elephant species, influence the structure of the environment they inhabit. Elephants exhibit complex patterns of social behavior between individuals within a population. Many behavioral studies focus on interactions among individuals within a population rather than broader trends related to group size. My study seeks to understand how male African savannah elephant group size is influenced by seasonality, age, physical condition and distance to permanent water resources. I examined the interaction of these variables in two ways: (1) a literature review of elephant behavior and conservation, and (2) an analysis of male …


Developing A Predictive And Dynamic Moose-Vehicle Collisions Model In Maine, Yue Yu Jan 2019

Developing A Predictive And Dynamic Moose-Vehicle Collisions Model In Maine, Yue Yu

Honors Theses

Wildlife-vehicle collisions are a major form of human-wildlife conflict. Predictive animal-vehicle collision models have been developed to identify collision hotspots in Maine and guide mitigation strategies. However, most current models are static and unable to produce dynamic forecasts that incorporate changing climate and weather. The goal of my study was to develop a predictive and dynamic model of animal-vehicle collisions in Maine, USA. More than 6,700 moose-vehicle collisions (MVC) occurred from 2003 to 2017 in Maine, raising road safety, socio-economic, and wildlife conservation concerns. I sought to identify factors that contribute to a higher probability of MVCs by comparing two …


Before Disaster Strikes: An Analysis Of Emergency Management Planning, Reagan Moody Jan 2019

Before Disaster Strikes: An Analysis Of Emergency Management Planning, Reagan Moody

Honors Theses

I have always been inspired by the outpouring number of volunteers that arrive to the scene of a natural disaster, ready to help in any way possible. With or without adequate training, these people arrive with warm hearts and helping hands. I admire their valiant efforts, however, it has prompted me to ask the question: If our citizens can respond so quickly in times of adversity, how are city governments preparing spontaneous volunteers for emergency management planning? The intent of this thesis is to properly evaluate the emergency management plans implemented in the cities of Baton Rouge, LA, Spokane, WA, …


Microbial Communities Associated With Dragonfly Nymphs Raised In Varying Concentrations Of Amoxicillin, Michelle Basha Jan 2019

Microbial Communities Associated With Dragonfly Nymphs Raised In Varying Concentrations Of Amoxicillin, Michelle Basha

Honors Theses

The bacteria on and within an organism make up that organism’s microbiome. Given interest in the use of antibiotics in agriculture and the effect of microbes on human health, more studies are needed on the microbial community composition of different organisms and how it responds to antibiotic use. This study investigated changes in the amount of antibiotic resistant bacteria present in dragonfly nymphs exposed to differing concentrations of amoxicillin. Next generation sequencing of the 16S rRNA gene was used to identify cultures of these antibiotic resistant bacteria. Increasing the concentration of antibiotics the dragonfly nymphs were exposed to resulted in …


Preliminary Study On The Effects Of Akkermensia Muciniphilia On Akt Phosphorylation In Diabetic Pig Models, Brian Ko Jan 2019

Preliminary Study On The Effects Of Akkermensia Muciniphilia On Akt Phosphorylation In Diabetic Pig Models, Brian Ko

Honors Theses

The onset of type 2 diabetes has been shown to affect the Akt signaling pathway, responsible for modulating cellular metabolism. The pro biotic Akkermensia muciniphilia has been recently shown to have an anti-inflammatory, anti-diabetic effect on animals inoculated with it, particularly within the Akt signaling pathway. This preliminary study utilized a twofactor experimental design with streptozotocin-induced diabetes and the presence of Akkermensia muciniphila in pig models in order to elucidate the probiotic's mechanism of action on the disease. Following analysis of insulin-sensitive tissues of muscle, pancreas, and liver, there was observed a mixed response to the presence of the probiotic …


Parent-Child Interaction Therapy As Treatment For Child Physical Abuse : Relation To Internalizing Symptoms, Emily Kaminsky Jan 2019

Parent-Child Interaction Therapy As Treatment For Child Physical Abuse : Relation To Internalizing Symptoms, Emily Kaminsky

Honors Theses

This paper explores the effectiveness of Parent-Child Interaction Therapy (PCIT) in reducing child internalizing symptoms in physically abused children as compared to the standard community group treatment. The data for this study was taken from a randomized control trial by Chaffinet al. (2004), which found that PCIT significantly reduced re-reports of physical abuse. The participants were 110 parent-child dyads referred by child welfare due to a recent report of child physical abuse. Both PCIT and the standard community group showed significant reductions in child internalizing symptoms over time, however there was no interaction effect between treatment group and time. Additionally, …


The End Times, Gunnar Ohberg Jan 2019

The End Times, Gunnar Ohberg

Honors Theses

The End Times is a collection of apocalyptic short stories set within the same universe. The stories employ elements of magical realism and grit lit. It is the author's hope that each story deal with at least one external societal issue (such as digital discourse and sexual aggression) and one internal psychological issue (such as depression, obsession/compulsion, and survivor's guilt). Each story is told in the first-person in an effort to best demonstrate the various psychologies of its protagonist. In these stories, God has decided to punish humanity for their transgressions. The devices of this God are fantastic: limbs disappear, …


Dworkinian Liberalism, The Right To Pornography, And The Internet, Will Nowell Jan 2019

Dworkinian Liberalism, The Right To Pornography, And The Internet, Will Nowell

Honors Theses

In a 1981 journal article, “Is There A Right to Pornography?,” Ronald Dworkin argues that we have a right to ethical independence that includes the right to consume pornography. The purpose of this thesis is to inquire as to whether Dworkinian liberalism does entail a right to specifically internet pornography. This research is primarily focused on Ronald Dworkin’s writings in Justice for Hedgehogs, Sovereign Virtue: The Theory and Practice of Equality, and Taking Rights Seriously to describe the principles and character of Dworkinian liberalism and its philosophical relationship to the question of the right to pornography. This thesis considers contemporary …


The Role Of The Age/Rage Signaling Pathway In Cardiac Fibroblast Migration, Mallory B. Harmon Jan 2019

The Role Of The Age/Rage Signaling Pathway In Cardiac Fibroblast Migration, Mallory B. Harmon

Honors Theses

Diabetes is one of the leading causes of death in the United States with around 30 million who suffer from diabetes and 84 million who are considered pre-diabetic. Diabetic individuals are at an increased risk for developing cardiovascular disease due to a stiffening of the left ventricle, which is thought to occur through fibroblast “activation” mediated by increased AGE/RAGE signaling. Advanced glycated end products (AGEs) accumulate within the body overtime and are accelerated under hyperglycemic conditions, and AGEs exert their effects by binding to their receptor (RAGE). Fibroblast “activation” is marked by elevated levels of α-smooth muscle actin expression and …


The Developmental And Behavioral Effects Of Early Life Stage Cannabinoid Exposure, Mariegene E. Almand Jan 2019

The Developmental And Behavioral Effects Of Early Life Stage Cannabinoid Exposure, Mariegene E. Almand

Honors Theses

As of 2019, marijuana legalization and decriminalization is sweeping the globe. Patients are increasingly using cannabis-derived compounds including Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) for treatment of diseases as diverse as epilepsy, Parkinson’s disease, and cancer. Furthermore, mothers are claiming that CBD oil decreases uncomfortable pregnancy side effects. While the adverse effects of chronic cannabinoid use and of cannabinoids on pregnancy have been previously investigated, the exact function of the endocannabinoid system, and its primary receptors, cannabinoid receptors 1 and 2, involved in producing these outcomes is still unclear. In this study, two strains of zebrafish embryos, namely fli and cnr2-/- …

Healthcare Practices Related To Neonatal Abstinence Syndrome, Muriel Mikayla Johnson

Honors Theses

The incidence of Neonatal Abstinence Syndrome (NAS) is abounding in hospitals across the nation due to the recent surge in opioid abuse. This thesis explores the variation in protocols and guidelines used by healthcare practitioners concerning NAS. This study consisted of a literature review as well as observations and interviews with healthcare practitioners in Neonatal Intensive Care Units (NICUs). The literature review revealed there has been a greater increase in NAS among rural areas, and there is currently no national standardized protocol for the treatment of NAS. Field notes taken during the interviews and observations confirmed the literature in that …


Analysis Of Atlantic And Northern Gulf Coast Wetland Bacterial Extracellular Enzyme Activity, Noah Kippenbrock Jan 2019

Analysis Of Atlantic And Northern Gulf Coast Wetland Bacterial Extracellular Enzyme Activity, Noah Kippenbrock

Honors Theses

Sea-level rise is projected to cause saltwater marshes to migrate landward replacing brackish and freshwater marshes. Coastal wetlands are important sinks of carbon, phosphorous, and nitrogen, so it is important to understand the function of their microbial communities. This study aims to categorize the difference in function between different spatially distinct wetland marsh types in advance of the expected alteration of the wetland ecosystems. Extracellular microbial enzymatic activity was measured to understand organic matter decomposition and nutrient mineralization in different marsh types. We measured the activities of the extracellular enzymes β-glucosidase, NAGase, peroxidase, phenol oxidase, and phosphatase across sites along …


Effects Of Vertical Transmission Of Maternal Antibodies To Mycoplasma Gallisepticum On Growth And Condition Of Eastern Bluebird Nestlings (Sialia Sialis), Mckenzie Xiang Denton Jan 2019

Effects Of Vertical Transmission Of Maternal Antibodies To Mycoplasma Gallisepticum On Growth And Condition Of Eastern Bluebird Nestlings (Sialia Sialis), Mckenzie Xiang Denton

Honors Theses

Mothers display maternal effects to influence the development and success of offspring through processes such as resource allocation. In birds, this occurs largely through the egg yolk with the vertical transmission of antibodies to offspring to protect the vulnerable young from disease. Specifically, poultry and eastern bluebirds across the eastern United States are commonly infected by the bacteria Mycoplasma gallisepticum (MG), for which mothers may produce antibodies against. To test for the vertical transmission of MG-specific antibodies from mothers to nestlings in eastern bluebirds and the associated fitness effects, bluebird boxes were set up and monitored during the field season. …


It's Not Just "Skin Deep": Social Anxiety And Anxiety Sensitivity In Adults With Psychodermatological Disorders, Lauren E. Ellison Jan 2019

It's Not Just "Skin Deep": Social Anxiety And Anxiety Sensitivity In Adults With Psychodermatological Disorders, Lauren E. Ellison

Honors Theses

Anxiety contributes to dermatological conditions and, due to the visible nature of skin conditions, social anxiety is particularly salient to dermatology patients. Although many dermatology outpatients report clinically significant social anxiety symptoms, there is little understanding of social anxiety among dermatology patients. Anxiety sensitivity (AS), or the fear of the consequences of anxiety, has been implicated in both social anxiety and dermatological symptoms. To this end, this study aimed to further elucidate the relation of social anxiety and AS among skin disease in two separate samples of individuals with psychodermatological conditions. We hypothesized that AS social, but not physical or …

Placing The Stateless Refugee: A Philosophy Of Statelessness, Nationality, And Rights, Ruby J. Gould Jan 2019

Placing The Stateless Refugee: A Philosophy Of Statelessness, Nationality, And Rights, Ruby J. Gould

Honors Theses

In this thesis, I many related questions regarding the fluctuating relationships between national communities and outsiders, specifically in the case of refugees and stateless peoples. After discussing the meanings of these terms, such as the definition and identities of the refugee and the nation-state, I delve into a philosophical examination of individual rights, particularly rights that are defended by nation-states, and the relationships between national communities and those existing outside of those communities whose lives may depend on their acceptance into a nation-state. I philosophically outline the likely experiences of refugees as they are faced with statelessness, including what forces …


Who Runs The World: The Impact Of The Gender Of Clerks On The Legal Profession, Taylor Bernstein Jan 2019

Who Runs The World: The Impact Of The Gender Of Clerks On The Legal Profession, Taylor Bernstein

Honors Theses

This paper investigates the role of gender on law clerks from the federal appellate clerks. There has been significant scholarship on the importance of the gender of judges and on the role and influence of law clerks; however, to this date there has been no analysis of how the gender of law clerks may or may not influence the clerkship experience. This honors thesis seeks to address that question and shed light on important aspects of the federal judiciary and the legal profession. I have approached this inquiry through descriptive and qualitative analysis, focusing on law clerks from this millennium. …


Examining The Effects Of Fadrozole, An Aromatase Inhibitor, On Testosterone And Estrogen Production Of Domestic Chicken Embryos (Gallus Gallus), Abby E. Joseph Jan 2019

Examining The Effects Of Fadrozole, An Aromatase Inhibitor, On Testosterone And Estrogen Production Of Domestic Chicken Embryos (Gallus Gallus), Abby E. Joseph

Honors Theses

The hypothalamic-pituitary-gonadal (HPG) axis is responsible for the production of the hormones testosterone and estradiol, and testosterone is thought to contribute to regulation of the axis through a negative feedback mechanism. Regulation by negative feedback involves the product of a pathway turning off that pathway when enough product is made. However, because the enzyme P450 aromatase converts testosterone to estradiol, estradiol may also contribute to regulation of the HPG axis and other phenomena that have been attributed to testosterone, like the inhibition of immune function. Previous studies have injected birds with an aromatase inhibitor (presumably reducing estradiol production) and shown …


The Effect Of Religion On Trait Priority In Potential Partners In Short And Long Term Relationships, Sara K. Glass Jan 2019

The Effect Of Religion On Trait Priority In Potential Partners In Short And Long Term Relationships, Sara K. Glass

Honors Theses

This study builds upon previous research that demonstrates how various demographic characteristics, as well as relationship type, affects trait preferences for potential mate partners. This study also explores the potential effects of religious affiliation and religiosity on trait preferences, as no previous research explicitly tests how individuals’ religious affiliation or strength of religiosity influences their rank ordering of potential partner traits. Seven hypotheses were proposed, as well as four points of exploration regarding sexuality, relationship status, religious affiliation, and race were proposed. Hypotheses 1, which predicted that women will rank financial stability higher than men and that men will rank …


Bridging Act-R And Project Malmo, Developing Models Of Behavior In Complex Environments, David M. Schwartz Jan 2019

Bridging Act-R And Project Malmo, Developing Models Of Behavior In Complex Environments, David M. Schwartz

Honors Theses

Cognitive architectures such as ACT-R provide a system for simulating the mind and human behavior. On their own they model decision making of an isolated agent. However, applying a cognitive architecture to a complex environment yields more interesting results about how people make decisions in more realistic scenarios. Furthermore, cognitive architectures enable researchers to study human behavior in dangerous tasks which cannot be tested because they would harm participants. Nonetheless, these architectures aren’t commonly applied to such environments as they don’t come with one. It is left to the researcher to develop a task environment for their model. The difficulty …

What Lies Beneath? : Removal Sampling To Test For Biases In Surface Activity Of The Eastern Red-Backed Salamander (Plethodon Cinereus), Amelia Tedesco

Honors Theses

In light of the current global amphibian extinction crisis from threats such as climate change and disease, reliable and repeatable sampling methods carry heavy importance for assessing North American salamander species.


Preparation Of A Perylenebisimide Acceptor With Serinol And Nonadecyl-Swallowtail Imides For Use In Molecular Rectification, Tarrah Frederick Jan 2019

Preparation Of A Perylenebisimide Acceptor With Serinol And Nonadecyl-Swallowtail Imides For Use In Molecular Rectification, Tarrah Frederick

Honors Theses

Several attempts were made to add 2-amino-1,3-propanediol to the acceptor perylene monoanhydride (PMA). The theoretical product, N-(10-nonadecyl)-N'-(1,3-dihydroxypropan-2-yl)perylene-3,4,9,10-bis(dicarboximide), is intended for use in unimolecular rectification because the perylenebisimide core is classified as a good acceptor due to its high electron affinity. Rectification usually utilizes donor-σ-acceptor molecules, whose localized orbitals permit electron transfer when placed between metal electrodes of asymmetric voltages. However, according to an “asymmetric rectification” analysis, an electron can pass from one electrode, through the LUMO of the acceptor, and then to the other electrode when said electrodes are held at certain voltages, and result in rectification if the acceptor …


Hit Me With Your Best Shot: A Critical Analysis Of The Resistance To Vaccine Utilization, Katherine Coleman Sistrunk Jan 2019

Hit Me With Your Best Shot: A Critical Analysis Of The Resistance To Vaccine Utilization, Katherine Coleman Sistrunk

Honors Theses

Vaccines have provided humans protection from infectious diseases for centuries, yet the vaccination rate in the United States fails to come near one-hundred percent, allowing vaccine-preventable diseases to re-emerge in communities across the nation. Vaccines have proven to be a safe and effective method in preventing the spread of infectious disease, but vaccine resistance remains high due to false information perpetuated by anti-vaxxers, greatly impacting the vaccination rate in our country. This thesis, by means of a literature review, provides a critical analysis the resistance to vaccine utilization in the United States to determine what policy recommendations and interventions can …


Carbon Dioxide Reduction Using Redox-Active Macrocyclic Catalysts, Dawson Kendall Buettner Jan 2019

Carbon Dioxide Reduction Using Redox-Active Macrocyclic Catalysts, Dawson Kendall Buettner

Honors Theses

The current energy crisis experienced by society today is in desperate need of a solution. Through carbon dioxide (CO2) reduction, we can reduce the amount of greenhouse gas that is warming our planet as well as create a source of renewable energy. Significant challenges currently inhibit the reduction of CO2 to more desirable products. Current limitations can be addressed through the design and synthesis of more efficient catalysts that are selective, durable, and operate close to the target thermodynamic potential of CO2 reduction. In this work, three redox-active macrocyclic ligands have been synthesized and studied for the development of potential …


The Protective Role Of Estrogen On Hiv-1 Mediated Neurotoxicity, Macklin Licamied Jan 2019

The Protective Role Of Estrogen On Hiv-1 Mediated Neurotoxicity, Macklin Licamied

Honors Theses

The prevalence of HIV among men have been in a steady inclination over the last several decades, yet the accelerated infection rate among older women is considerably concerning. Not only does the HIV virus affect the immune system but it also affects the central nervous system. One of its viral proteins, Tat, acts as an excitotoxin and disrupts the cell’s membrane potential by increasing the concentration of Ca2+ inside the cell. This influx of calcium ions leads to apoptosis and secretion of the cell’s contents into the surrounding area. Macrophages, along with other innate immune components, gather and induce the …


Unexpected Outcomes During The Attempted Iodination Of Biphenol, Henry Nguyen Jan 2019

Unexpected Outcomes During The Attempted Iodination Of Biphenol, Henry Nguyen

Honors Theses

The goal of this research was to create a new procedure to iodinate 4,4- biphenol using a ball miller. Iodination of 4,4-biphenol was first attempted in solution using electrophilic aromatic substitution. Several attempts were made to iodinate 4,4-biphenol, but the general insolubility of crude products inhibited progress. Interestingly, NMR analysis of the aqueous ammonia product suggested that 4,4-biphenol dimerized or polymerized with itself to make an ether. The exact mechanism by which the ether dimer was created is unknown, but the reaction may have occurred using a radical mechanism. Though the original goal of the project is left unmet, a …


Differential Analysis Of Gene Expression In Arabidopsis Thaliana Organ Boundary Mutants, Jack Mason Jan 2019

Differential Analysis Of Gene Expression In Arabidopsis Thaliana Organ Boundary Mutants, Jack Mason

Honors Theses

Differences in gene expression occur due to cell type differentiation, the stages of an organism’s life cycle, genetic variation, and changes in the environment. The quantification of these changes can be valuable for helping deduce the molecular mechanisms underlying the development of model organisms such as Arabidopsis. A pair of homeobox genes, ARABIDOPSIS THALIANA HOMEOBOX GENE1 (ATH1) and SHOOT MERISTEMLESS (STM), encode transcription factors that play key roles in establishing organ boundaries in Arabidopsis flowers. Plants that carry mutations in both of these genes are missing floral organ-stem boundary regions and fail to shed their outer floral organs. Previous studies …


Hydrogen Production By His Mutants Of Artificial Hydrogenase, Emory Elizabeth Wills Jan 2019

Hydrogen Production By His Mutants Of Artificial Hydrogenase, Emory Elizabeth Wills

Honors Theses

Nickel enzymes are relatively new to be studied, but they have been found to be useful in creating artificial hydrogenases. Nickel alone can be harmful, but when combined with proteins to create an enzyme, the hope is that through catalysts, hydrogen can be produced for viable energy. The proteins used in the experiments had respective mutations at points 113 and 26. The cysteine at both of these points was replaced by a histidine to hopefully enhance metal binding. To create artificial hydrogenases and produce energy, the proteins were induced by various metals including nickel, copper, and cobalt. After experimentation and …
