Lucumí Language Preservation In Cuban Literature: A Study Of Miami Santeros’ Perceptions, Dayni Deysi Diaz Mederos

Electronic Theses and Dissertations

Santería is an Afro-Cuban religion that has played a significant role in shaping Cuba’s cultural identity and that of its diaspora. Lucumí, a liturgical language primarily derived from Yoruba, is at the core of its religious practices. This language has been incorporated into the works of Cuban writers such as Lydia Cabrera, Alejo Carpentier, Nicolás Guillén, Miguel Barnet, and Nancy Morejón. While previous scholarship has examined Lucumí from linguistic and literary perspectives (Olmstead, 1953; Castellanos, 1939; Concordia, 2012; Ramos, 2013; Matibag, 2017), little attention has been given to how santeros, practitioners of Santería, perceive the representation of their sacred language …

Structure And Function Of Sulfated Fucans And Fucosylated Chondroitin Sulfates: Therapeutic And Mechanistic Insights, Marwa Farrag

Electronic Theses and Dissertations

Glycosaminoglycans (GAGs) are heteropolysaccharides widely exploited in the clinic and as molecular models in biomedical research. Marine-derived GAG analogs, particularly sulfated fucans and fucosylated chondroitin sulfates exhibit unique and diverse glycan motifs that are not found in the typical mammalian GAGs.

On Planar Brownian Motion Singularly Tilted Through A Point Potential, Barkat Mian

Electronic Theses and Dissertations

We construct a family of time-inhomogeneous two-dimensional diffusion processes, defined over a finite time interval [0, T]. These diffusions have transition density functions that are given by the integral kernels of the semigroup corresponding to the two-dimensional Schrödinger operator with a point potential at the origin. Although, in a few ways, our processes of interest are closely related to two-dimensional Brownian motion, they have a singular drift pointing in the direction of the origin that is strong enough to enable the possibility of visiting there with positive probability. Our main focus is on characterizing a local time process at the …

Missing Physics Or New Physics? Understanding Biases In Gravitational Wave Tests Of General Relativity, Purnima Narayan

Electronic Theses and Dissertations

Gravitational wave (GW) observations from binary black hole (BBH) coalescences offer a powerful means of probing general relativity (GR) in its most extreme regime: the strong- field, highly dynamical merger phase. One can compare observed signals to theoretical waveform models to constrain possible deviations from GR. However, the reliability of such comparisons can be compromised by waveform systematics, especially when key physical effects are not incorporated into the models. This dissertation investigates the impact of three such missing physical effects: orbital eccentricity, strong gravitational lensing, and waveform systematics due to precession, higher-order modes, and memory on standard GW tests of …

Beyond Guns Vs. Butter: Gendered Dynamics In Security Policy Preferences, Elaine Elizabeth Tagert

Electronic Theses and Dissertations

This dissertation challenges the foundational assumptions of the “guns versus butter” debate by recentering gender, insecurity, and state legitimacy in the analysis of public opinion. Drawing on over 300,000 individual responses across 80 countries, and original survey data from post-conflict Colombia, it demonstrates that the commonly held belief that women are more likely to prioritize welfare over security is both context-dependent and empirically unstable. Rather than reflecting innate preferences, gendered policy attitudes emerge from lived experiences of violence, inequality, and institutional trust.

The first empirical chapter reveals a striking reversal of conventional expectations in the Global South: in regions where …
