Grooming Solicitation & Hierarchy In Cercopithecus Petaurista, Ryan Domitz

The Pegasus Review: UCF Undergraduate Research Journal

Allogrooming is a behavioral adaptation present in many primate systems that serves to organize social hierarchies and promote social cohesion by placating future agonistic conspecifics. Lesser Spot-Nosed Guenons (Cercopithecus petaurista) are one species that exhibits allogrooming both in the wild and in captive populations. In a population of C. petaurista, dominant males perform proportionately less allogrooming than do females, possibly indicating dominant individuals are the recipients of higher rates of allogrooming than are subordinate ones. My case study catalogs the activity budgets of three captive Lesser Spot-Nosed monkeys and investigates the relationship between allogrooming, solicitation of allogrooming, and aggression. It …

The Brothers: A Study Of The Social Structure Between Two Captive Cheetahs, Chenienne Clemens

The Pegasus Review: UCF Undergraduate Research Journal

Cheetahs (Acinonyx jubatus) are easily differentiated among other Felids. They exhibit unique physiological features, and their type of social structure has not been seen in any other species of Felid. Coalitions of male cheetahs are seen both in the wild and in captivity, while female cheetahs remain solitary. This paper is a compilation of a twelve-week observational study of the two male cheetahs at the Central Florida Zoo in Sanford, Florida. The focus of the study was the social structure between the two related individuals. The observational data showed that there is a lack of any hierarchy or …

Featured Bookshelf: 2019 Women's History Month, Megan M. Haught

Featured Bookshelf

Women’s History Month began as a week-long celebration by in Sonoma, California in 1978 which was centered around International Women’s Day on March 8. A year later during a women’s history conference at Sarah Lawrence College, participants learned how successful the week was and decided to initiate similar in their own areas. President Carter issued the first proclamation for a national Women’s History Week in 1980. In 1987, Congress (after being petitioned by the National Women’s History Project) passed Pub. L. 100-9 designating March as Women’s History Month. U.S. Presidents have issued proclamations on Women’s History Month since 1988.

Activity Budgets And Behavior Of Captive Black-Handed Spider Monkeys (Ateles Geoffroyi) At The Central Florida Zoo And Botanical Gardens, Stephanie Hargrave

Honors Undergraduate Theses

Establishing baseline activity budgets for zoo-housed captive animals can be important in tracking behavior changes that may indicate medical or other concerns, as well as assessing overall welfare and the need for implementation of interventions such as increased amounts of enrichment. This study sought to calculate activity budgets for the current spider monkeys residing at the Central Florida Zoo, a father-daughter pair of Ateles geoffroyi. Having a baseline activity budget is also valuable because major changes in behavior may accompany the upcoming introduction of new individuals to this particular group of spider monkeys. BORIS behavior coding software was used to …

Computational Fluid Dynamics Investigation Of A Novel Hybrid Comprehensive Stage Ii Operation For Single Ventricle Palliation, Marwan Hameed

Electronic Theses and Dissertations

Hypoplastic left heart syndrome (HLHS) is a type of heart defect where the left ventricle is underdeveloped or not developed, resulting in only a single functioning right ventricle. Approximately 7.5% of patients with congenital heart disease are born with a single ventricle (SV) which is accompanied by a spectrum of other malformations such as atrophied ascending aorta, atrial septal defects, and ventricular septal defects (VSD). The existing three-hybrid staged surgical approach serving as a palliative treatment for this anomaly entails multiple complications and achieves a survival rate of only 50%. To reduce the trauma associated with the second stage of …

Parameter Estimation Of Stochastic Models Against Probabilistic Temporal Logic Behavioral Specifications, Arfeen Khalid

Electronic Theses and Dissertations

The inherent behavioral variability exhibited by stochastic systems makes it a challenging task for human experts to manually analyze them. Computational modeling of such systems helps in investigating and predicting the behaviors of their underlying processes but at the same time introduces the presence of several unknown parameters. A key challenge faced in this scenario is to determine the values of these unknown parameters against known behavioral specifications. The solutions that have been presented so far estimate the parameters of a given model against a single specification whereas a correct model is expected to satisfy all the behavioral specifications when …

Development Of Luminescent Tools For Use In The Study Of Mycobacterium Tuberculosis, Krista A. Moore

Honors Undergraduate Theses

Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is a growing problem worldwide due to the emergence of multi-drug resistant and extensively-drug resistant strains of the bacteria. A key to combatting the spread of these strains lies in the understanding of gene expression occurring in Mtb. This study focuses on the development and optimization of a luciferase-based bioluminescent transcriptional reporter that can be used to monitor gene expression in Mtb. The luminescent signal emitted from the reporter can be measured and correlated with the level of transcription of certain genes. This study focuses specifically on a gene called whiB7 which …

How The Body Moves The Mind: Exploring The Effects Of Perspective Of Physical Sensation On Embodied States And Perception, Kathryn G. Satoski

Honors Undergraduate Theses

The purpose of this thesis is to explore how surface engagement through touch affects perception of stimuli and mood. Researchers have found psychological, physiological and cognitive benefits associated with exposure to and interaction with nature. Stress Reduction Theory with Psychoevolutionary framework, and Attention Restoration Theory are often used to explain and interpret results. However, studies that focus on individuals with negative perspectives of nature find a positive affective response to nature is not universal. Rather, individuals respond differently based on their own experience with nature. Childhood exposure and culture have been found to influence attitudes towards nature. Theories of embodied …

The Hyperaccumulation Of Zinc In Sunflowers And Its Effect On Disease Resistance, Rayner J. Seavey

Honors Undergraduate Theses

Sunflowers are considered to be a part of a group of plants known as hyperaccumulators that share the ability to accumulate high amounts of heavy metals in the above ground organs, far in excess of the levels found in other species, often without suffering any phytotoxic effects. Quantifying the effects of zinc accumulation through the lens of the elemental defense hypothesis is essential for uncovering if there is a means to increase herbivore resistance in agricultural settings without the use of external interventions such as pesticides. A greenhouse study was conducted on four widely grown commercial cultivars of sunflower. Each …

The Effects Of Matrix Metalloproteinase-9 On Cx3cl1 Shedding And Axon Retraction, Lauren A. Dobrie

Honors Undergraduate Theses

Spinal cord injury (SCI) often leads to irreversible damage, and permanent paralysis inferior to the injury is common (Leibinger et al., 2013). Injury to the spinal cord occurs in two phases. In the first phase, components of the spinal cord are subject to mechanical trauma causing direct damage. In the second phase, damage spreads from the area of injury through molecular processes. Several studies have linked M1 "pro-inflammatory" macrophages to exacerbation of damage by inducing dieback of dystrophic axons, but not healthy axons, through direct cellular contact. Several studies have identified the presence of macrophage subtypes at specific time. A …

Is Perceived Intentionality Of A Virtual Robot Influenced By The Kinematics?, Jordan Sasser

Honors Undergraduate Theses

Research has shown that in Human-Human Interactions kinematic information reveals that competitive and cooperative intentions are perceivable and suggests the existence of a cooperation bias. The present study invokes the same question in a Human-Robot Interaction by investigating the relationship between the acceleration of a virtual robot within a virtual reality environment and the participants perception of the situation being cooperative or competitive by attempting to identify the social cues used for those perceptions. Five trials, which are mirrored, faster acceleration, slower acceleration, varied acceleration with a loss, and varied acceleration with a win, were experienced by the participant; randomized …

Effects Of A Plant-Based Vegan Diet On The Risk Of Cancer: An Integrative Review Of The Literature, Chelsie M. Silavent

Honors Undergraduate Theses

Cancer, an aggressive chronic disease, impacts the lives of millions of people every day. There are numerous proposed triggers related to the diagnosis and much remains to be learned about the causes. Associated with this disease's variability is the challenge to identify a single causative agent that lead to its prevention. Specific topics that need additional evidence relate to environmental factors and lifestyle behaviors in the development, treatment and, in some instances, even suppression of disease progression. Specifically, a diet that excludes animal-based products but consists of a variety of fruits and vegetables (i.e., plant-based vegan diet) is reported to …

The Effect Of Corporate Social Responsibility On Firm Value And Performance, Jennifer E. Maxey

Honors Undergraduate Theses

In this thesis, I test the effects of corporate social responsibility (CSR) on firm valuation and performance from the financial crisis of 2007 to year 2013. Prior research on CSR suggests that CSR is related to firm performance, but the results have not been consistent. My study focuses on the time period following the crisis since trust between firms and stakeholders may be more important following a negative shock. The components of CSR are broken out into environmental, human rights, diversity, community impact, employee relations, product, and corporate governance. I find evidence that at least some measures of firm performance …

Effect Of Propionic Acid-Derivative Ibuprofen On Neural Stem Call Differentiation; A Potential Link To Autism Spectrum Disorder, Aseelia Samsam

Honors Undergraduate Theses

Propionic acid (PPA) is a short chain fatty acid that is produced by the human gut microbiome. Propionate, butyrate and acetates are the end products of the fermentation of the complex carbohydrates by human gut friendly microbiome and are being used as sources of energy in our body. PPA is used as a food preservative against molds in various daily products and has been implicated in the pathogenesis of autism. In a recent study we showed that PPA in human neuronal stem cell (NSC) culture increases the astrocyte population and decreases the neuronal number and increases the inflammatory cytokines. In …

The goal will be to take this research one step further into the analysis of textile fibers by RGB value analysis and birefringence. The RGB values will …

Exploring Galvanic Replacement As A Method To Engineer Peroxidase-Mimics Nanoparticles, Kuryn T. Magloire

Honors Undergraduate Theses

Peroxidase enzymes are of critical importance within the scientific community for their applications in biosensing assays. In a living system, natural peroxidases function as catalysts in the oxidation of peroxide (e.g., H2O2) - a harmful byproduct of aerobic processes and convert them into harmless compounds. Such an ability allows peroxidases to serve as labels in biosensing assays, where they are conjugated to antibodies and accurately produce a detection signal by catalyzing substrates. However, due to intrinsic limitations, namely instability, Peroxidase made of proteins substantially inhibit broader applications.

Alternatively, nanoparticles produced from noble metals have been found to exhibit peroxidase-like abilities …

Current Perceptions Of Undocumented Immigrants In The United States, Gabriela Lozano

Honors Undergraduate Theses

The intent of this thesis is to examine current perceptions that U.S. Americans have about immigrants coming to the U.S. illegally/ undocumented. There is currently an ongoing debate around immigration in today's political climate. Historically, immigration has always happened in the U.S. and has sparked a vast array of feelings from the U.S. population (Obinna 2018). This study aims to contribute to the existing literature on undocumented immigration to the U.S. and opinion surrounding it. The current study uses the opinion of 177 people to compare current perceptions of undocumented people based on gender, income, and political standing. This study …

Metabolic Effects Of 17a-Estradiol Are Growth Hormone Independent And Sex Specific, Silvana Sidhom

Electronic Theses and Dissertations

Aging is a major risk factor for metabolic syndromes and type two diabetes. With growing elderly populations worldwide and increasing incidence of age-related diseases there is a great need to develop pharmacological interventions that would delay aging and protect from age-related diseases. 17-alpha estradiol (17α-E2) is an epimer of the primary female sex hormone estradiol and has been shown to extend lifespan and downregulate markers of age-related metabolic dysfunction in male mice. Because 17α-E2 does not induce feminization in males it holds potential as a novel therapeutic in humans for age-related metabolic dysfunction. Importantly, we have previously shown that 17α-E2 …

Identification And Functional Characterization Of A Long Non-Coding Rna Associated With Prostate Cancer, Md Faqrul Hasan

Electronic Theses and Dissertations

Prostate cancer is the most common cancer in men in the western world. Although early stage prostate cancer is treatable late stage, more specifically, metastatic and drug resistant prostate cancers are mostly incurable. The failure of current treatments obligates the research community to explore novel areas in prostate cancer biology and find better therapeutic targets. Emerging evidences show that non-coding RNAs specifically long non-coding RNAs (lncRNAs) play regulatory roles in various cellular processes and are frequently dysregulated in cancer including prostate cancer. These aberrantly expressed lncRNAs mostly with unexplored genetic information may drive cancer progression. Previous studies done in our …

Development Of A Functional Testing Platform For The Sensory Segment Of The Neuromuscular Reflex Arc, Alisha Colon

Electronic Theses and Dissertations

Investigations of human biology and disease have been hindered by the use of animal models. The information obtained from such studies often results in clinically irrelevant results and drug trial failures. Additionally, several governing bodies have been formulating legislation to move away from animal models and toward more ethical and efficient testing platforms for drug discovery and cosmetic research. As an answer to these issues, "body-on-a-chip" systems have been a rapidly developing field which easily recapitulates in vivo functionality, providing a more relevant, repeatable, and ethical testing platform to better predict biology. These systems can be used as human-based testing …

Filling The Gaps: Common Bottlenose Dolphin (Tursiops Truncatus) Population Dynamics, Structure, And Connectivity Within Florida Panhandle Bays, Sounds, And Estuaries, Christina Toms

Electronic Theses and Dissertations

At the time of the Deepwater Horizon oil spill in 2010, very little was known about the inshore bottlenose dolphin (Tursiops truncatus) populations hit hardest by the spill. Without previous population demographic data impacts were challenging to assess. My dissertation was designed to build research capacity moving forward by helping to fill data gaps in the western Florida Panhandle. The first study presented here resulted in the first system-wide assessment of seasonal abundance, survival, and site fidelity patterns of bottlenose dolphins that inhabit the Pensacola Bay system. In contrast to a previous study that reported only 33 dolphins, results from …
