A Darling Legacy: The Hollins Darlings and the Continued Queer Legacy at Hollins
No full textUnder the direction of Isabel Folck
Through a mixed physical and digital media, a non-linear picture of a continued queer legacy at Hollins University. The ever evolving and changing timeline of queer history in the United States with a focus on issues directly relating to Hollins University and its legacy allows multi-generational connections to be drawn leading from the 20th century gender non-conforming Cotillion Club to the mid to late 2010s changing narratives surrounding historical women’s colleges in debates of undergraduate transgender student admission. Using photographs and artifacts relating to the Hollins Darlings from the Hollins archives, alongside a digital libguide for queer studies materials available at the Wyndham Robertson Library, a framework for continued studies of queer history and its impact on Hollins University’s legacy can be upheld and updated as needed
Tuning electronic and steric properties of diphosphines: synthesis and characterization of Ph₂PCHRPPh₂ variants
Get PDFUnder the direction of Dr. Daniel Derringer This study explores the synthesis and characterization of diphosphines of the type Ph₂PCHRPPh₂, focusing on the variability of the R group to tune electronic and steric properties. We have successfully synthesized and analyzed Ph₂PCH(CN)PPh₂ and Ph₂PCH(CH₃)PPh₂, demonstrating significant differences in their electronic and steric profiles. Building on this foundation, we aim to synthesize Ph₂PCH(CCl₃)PPh₂, hypothesizing that the introduction of the CCl₃ group will further modulate the ligand\u27s properties. Preliminary results indicate promising pathways for the synthesis of Ph₂PCH(CCl₃)PPh₂, which could offer unique advantages in coordination chemistry and catalysis. Further studies will focus on optimizing the synthesis process and evaluating the ligand\u27s performance in various catalytic applications
Maternal Childhood Trauma and How that Impacts Infants
Get PDFUnder the direction of Dr. Seunghee Han
I am proposing a study on maternal adverse experiences in childhood and adulthood. Maternal adverse experiences in childhood or adulthood can have a significant impact on their relationships with their infants. The severity of their adverse experiences is a large factor. It is important to see how these things impact infant development based on previous research. I plan to conduct interviews, self-report questionnaires, and to assess the relationship effectively through more objective measures. Not a lot of research has been done on these things, so I propose these methods
When do jumps matter? A comparison of Black-Scholes and Merton Jump Diffusion models in pricing European Options
No full textUnder the direction of Dr. Giancarlo Schrementi
In 1973, Fischer Black and Myron Scholes introduced the Black-Scholes model as an objective quantitative method to price options that do not pay dividends. Over the years, this model has been modified to cover more complex derivatives and stocks, providing a foundational framework for traders and investors to understand option pricing in a systematic way. The formula is based on key assumptions that the volatility of the underlying asset remains unchanged through time and that the market returns should follow a constant log-normal distribution. However, these ideal assumptions do not always hold in practice, and one famous adaptation of the Black-Scholes formula is the Merton Jump Diffusion model, which extends the original framework by incorporating sudden jumps in the underlying asset price. Previous works comparing these two models have shown that although the Merton Jump Diffusion model is generally considered a better version of Black-Scholes, it does come with disadvantages. When varying the strike price and considering different types of moneyness, Merton Jump Diffusion produces less accurate results unless hyperparameters such as jump intensity and magnitude are set at low values. The goal of this research is to confirm these facts using European call-and-put options from leading companies: Coca-Cola and BioNTech. Since both companies are in different fields with contrasting stock behaviors and characteristics, this difference allows us to evaluate Merton Jump Diffusion and Black-Scholes performance under different types of moneyness and strike price. Specifically, we will use Python to compare the accuracy of Black-Scholes and Merton Jump Diffusion models in valuing Coca-Cola and BioNTech call options under real-time conditions. We further vary the strike price to consider how the moneyness can impact the degree of mispricing. Finally, we discuss potential limitations of each model and conclude that since this project merely focuses on pricing simple call-and-put options, further research is needed to validate whether similar patterns are applied to other types of derivative
Unveiling the Wilis: Exploring Giselle\u27s Slavic Folkloric Origins and the Ramifications of Essentialized Femininity
Get PDFJules Perrot and Jean Coralli’s choreography of Giselle’s wilis continues to influence the essentialized femininity in Ballet Blanc. The folkloric víla origins of the wilis create a direct contradiction to the archetypal ballet woman. The celebrated story of Ballet Blanc’s Giselle conflates the Slavic origins and wili characteristics, while simultaneously abandoning key characteristics of the Slavic víla. Antonia Dougherty’s thesis endeavors to unify these distinct components of the víla and their symbology so that a gender critical analysis of the essentialized femininity of Ballet Blanc’s Giselle may be explored. Perrot and Coralli used the Slavic folkloric víla origins to create the character of the wilis, and the juxtaposition within this thesis proves the essential traits that were lost. The lost characteristics lead to the emergence of the performative of a heteronormative social construct, as outlined by Judith Butler’s gender theory. The Ballet Blanc’s essentialized femininity construct bled into the influence and power of George Balanchine, as seen in Ann Daly’s Balanchine’s Woman. Dismantling Ballet Blanc’s gender norms and reclaiming stereotypical floral imagery, as seen in Art Nouveau’s Alphonse Mucha, serves as the disruption of the wili narrative and an intentional rewrite of the Slavic víla origins. The recasting of the víla integrates agency and autonomy to Ballet Blanc’s femininity through barefoot dancing, improvisations, and shapeshifting as a modifying element in the generation of movement. In conclusion, Dougherty’s personal connections through Slavic matrilineage and her journey reimagining the role and embodiment of the wili, advance an intimate transfiguration of a liberated ballet femininity
