Physiological Indicators Of Menstrual Cycle Phase: A Two-Part Study On Developing A Method Of Menstrual Cycle Phase Determination And Assessment Of Menstrual Cycle Impacts On Brain Activation, Anna Feldbush Jan 2022

Physiological Indicators Of Menstrual Cycle Phase: A Two-Part Study On Developing A Method Of Menstrual Cycle Phase Determination And Assessment Of Menstrual Cycle Impacts On Brain Activation, Anna Feldbush

Theses & ETDs

The menstrual cycle, and associated variations in hormone status, are a powerful moderator of both behavioral and physiological variables. However, current methods of determining menstrual cycle phase in research are largely unreliable and often cumbersome to put to use in a study. This two-part study examined two bio-markers of menstrual cycle phase for the application in research. Study 1 assessed the viability of salivary ferning - a crystal pattern formed in dried saliva that is linked to ovarian hormone status -- in identifying menstrual cycle phase. The two sampling types used in this study demonstrated that although salivary ferning patterns …

Modeling Ecological Interactions Between Two Species Of Parasitoid Wasps, Michelle Voight Jan 2022

Modeling Ecological Interactions Between Two Species Of Parasitoid Wasps, Michelle Voight

Theses & ETDs

The competitive exclusion principle is a commonly accepted notion within ecology; it asserts that two species with identical niches can not coexist indefinitely over ecologi- cal time. The Lotka-Volterra model of competition explores this notion by predicting the outcome of competitive events between two species. Using data on two species of parasitoid wasps, Nasonia vitripennis and Melittobia digitata, this model was ap- plied to determine the outcome of interspecific competition. The analysis found the population growth of M. digitata was possibly negatively impacted by the presence of N. vitripennis. Comparatively, the results indicated N. vitripennis was likely to be either …

Examining The Role Of Premenstrual Symptomatology In Emotion Regulation, Interoceptive Awareness, & Cortisol Reactivity To Competition, Sophia Laney

Theses & ETDs

Premenstrual disorders, including premenstrual dysphoric disorder (PMDD), are defined by significant fluctuations in mood, behavior, and cognition across the menstrual cycle that are inextricably linked to a differential sensitivity to cyclical hormone changes. This thesis aimed to investigate several psychological and biological correlates of premenstrual symptomatology, including emotion regulation difficulties and interoceptive abilities, as well as how premenstrual disorders are connected to cortisol reactivity and competitive stress. Two different studies were conducted to achieve this. In Study 1, self-reports, along with a competitive behavioral task and hormone assay data, were used to assess 54 participants’ extent of premenstrual symptomatology, cortisol …

Indigenous Aesthetics And Post-Revolutionary Nationalism: Defining Mexicanidad Through The Popular Arts And The Best-Maugard Method, Katie Margerison

Theses & ETDs

After the Mexican Revolution ended in 1920, President Álvaro Obregón (1920-1924) enacted a national reconstruction plan that aimed to establish a unified national identity through visual culture. The plan foregrounded efforts toward the cultural inclusion and integration of Mexico’s substantial yet marginalized indigenous population. Through a variety of government-sponsored events, initiatives, and educational programs related to the visual arts, Obregón sought to unify the nation by promoting indigenous culture as integral to Mexican identity. In this thesis, I examine the key ways in which Obregón’s administration was involved in popularizing indigenous aesthetics and integrating them into modern Mexican culture, while …

Patio Pollinators: Teaching Wildlife Gardening And Appreciation Through A Video Game, Malakai Hall Jan 2022

Patio Pollinators: Teaching Wildlife Gardening And Appreciation Through A Video Game, Malakai Hall

Theses & ETDs

Pollinator populations are in decline globally. Pollinator gardens, even small ones, play a vital role in supporting urban pollinator populations. The beneficial effects of pollinator gardens are increased when the gardens are planted with native species. However, figuring out which species are native to a given area and which ones are best for pollinators takes time and energy that may deter many from starting a garden. Given the teaching power of games, I have created a video game that teaches its players to establish and care for a pollinator garden with flora native to the Sarasota area. The purpose of …

Corals, Cassiopea, And Climate Change: An Assessment Of Cassiopea Xamachana As A Model Organism For Coral-Algal Symbioses, Caroline Link Jan 2022

Corals, Cassiopea, And Climate Change: An Assessment Of Cassiopea Xamachana As A Model Organism For Coral-Algal Symbioses, Caroline Link

Theses & ETDs

The driving force between the high biodiversity and productivity of coral reefs is corals’ symbiotic relationship with photosynthetic dinoflagellates within the family Symbiodiniaceae. Recent studies have found that Symbiodiniaceae species differ in their physiological thermotolerances and that symbiont identity is a key determinant of a coral host’s susceptibility and acclimation to increased temperature. However, the specific thermotolerances between species and among species strains remain partially unknown. This is due in part to the difficulty associated with maintaining ex hospite symbionts in culture and sourcing intact coral-algal holobionts with a symbiont that has known physiology when in culture. Cassiopea xamachana jellyfish, …

Conceptual Metaphor Games An Embodied Approach To Mathematics Pedagogy, Laura Perkins Jan 2022

Conceptual Metaphor Games An Embodied Approach To Mathematics Pedagogy, Laura Perkins

Theses & ETDs

In the theory of embodied cognition, mathematical activity is thought to be facili- tated in large part by epistemic “mappings” that translate bodily intuitions about the world into abstract conceptual domains. Since their popularization, these ideas have influenced discourse in mathematics education. Another currently popular topic in mathematics education is the growing evidence that learning games can enhance learning outcomes. Combining these facts, this work proposes to construct real- world or virtual games which directly map onto mathematical concepts via concep- tual metaphors. Games of this kind, which I dub conceptual metaphor games, intend to encourage learning as exploration, making …

Effects Of Multicollinearity In Variable Selection Algorithms, Atalay Kutlay Jan 2022

Effects Of Multicollinearity In Variable Selection Algorithms, Atalay Kutlay

Theses & ETDs

Variable selection algorithms are used to find the predictor variables that have a correlation with the response variable. Having a correlation among predictor variables is not desired, as it poses issues in separating their respective effects on the response. This phenomenon, called ”multi-collinearity”, generally implies a strong linear inter-relationship between predictors. In this thesis, we compare variable selection algorithms - Stepwise, LASSO, and Sparse Principal Component Regression - and their performance of picking the right set of predictors under various levels of multi-collinearity. We perform simulations with randomly generated datasets according to various parameters controlling the severity of multi-collinearity, the …

Sleeping With The (Cuttle)Fishes: Measuring Sleep Through Arousal Threshold In The Dwarf Cuttlefish, Sepia Bandensis, Hannah Nations Jan 2022

Sleeping With The (Cuttle)Fishes: Measuring Sleep Through Arousal Threshold In The Dwarf Cuttlefish, Sepia Bandensis, Hannah Nations

Theses & ETDs

Sleep is a fundamental part of life, not only for humans, but for countless species. Using behavioral criteria, sleep has been found to occur in species from a large range of phyla, including Mollusca. So far it has been found that one octopus species displays sleep behaviors, and one cuttlefish species fulfills multiple behavioral criteria for sleep. This study uses Sepia bandensis, the dwarf cuttlefish, to test a remaining criterion: an elevated arousal threshold that provides evidence of sleep behavior in cuttlefish. To test arousal threshold, the magnitude of stimuli required to evoke a response, when in and out of …

The Effects Of Climate Change On The Migration Phenology Of Juvenile Blacktip Sharks (Carcharhinus Limbatus), Victoria Goldner Jan 2022

The Effects Of Climate Change On The Migration Phenology Of Juvenile Blacktip Sharks (Carcharhinus Limbatus), Victoria Goldner

Theses & ETDs

Seasonal temperature change has been shown to be a key driver of migration for many species. Increasing ocean temperatures have been observed to cause shifts in the range and timing of migratory movements in marine animals, including sharks. For harvested species, these behavioral changes could have significant implications for fisheries management. The blacktip shark (Carcharhinus limbatus) is one of the Gulf of Mexico’s most recreationally and commercially important species. Terra Ceia Bay, FL, is a nursery for blacktip sharks that has been extensively studied. In the late 1990s through early 2000s, young-of-the-year sharks were found to reside in the bay …

Pediatric Heavy Metal Toxicity: A Systematic Review Of The Association Between In-Utero Exposure To Heavy Metals And Behavioral/Neurological Problems In The Affected Children, Isabella Hochburger

Theses & ETDs

The rates of children diagnosed with developmental disorders such as autism spectrum disorder (ASD) and attention-deficit hyperactivity disorder (ADHD) have exponentially increased over the last 20 years, which has placed a heavy burden on both caregivers and psychiatrists. The neurobiology of these disorders has been increasingly well studied, but the root causes of these disorders remain poorly understood by the neuroscience/psychiatric community. Most neuroscientists suggest a combination of genetic and environmental factors are to blame, but the question remains: why are these disorders becoming so prevalent in our society, now more than ever before? One proposed genetic-environmental factor is heavy …
