Women and Time: Food Work Politics of Self Defined Healthy Men
This study examined the way gender operates in relation to time within the food work spectrum discussed in 19 narratives. The 19 narratives came from individual open ended face-to-face interviews with self-defined healthy men who shop at healthy food stores. This study's examination of how gender …

An Empirical Analysis of the Association Between Types of Interventions and Civil War Onset
Quantitative studies have focused on economics, social structures, and lack of political freedoms as being elemental factors for civil war onset. However, these studies have neglected the possibility of a civil war being an unintended consequence of international military intervention. I conduct an …

Resistive Pulse study of Vesicles and Liposomes
In this work, the properties of the liposomes, the artificially created vesicles by various methods, are explored by a resistive pulse method using micropipettes. The fact that vesicles are fundamental in the wide range of functionalities they fulfill as organelles strengthen the desire of …

Synthesis of Fluorescent Molecules and their Applications as Viscosity Sensors, Metal Ion Indicators, and Near-Infrared Probes
The primary focus of this dissertation is the development of novel fluorescent near-infrared molecules for various applications. In Chapter 1, a compound dU-BZ synthesized via Sonogashira coupling reaction methodology is described. A deoxyuridine building block was introduced to enhance hydrophilic …

Can I Get an Amen? Central Florida Black Pastors' Perceptions of the Impact of the Black Church in the Black Community
This study uses phenomenological methods to answer the research question, “what do black pastors perceive as the role of the church in the black community?” I asked 20 Central Florida black pastors 17 questions, most of them open-ended, to determine their perceptions of the current black church. …

Convective Heat Transfer in Quasi-one-dimensional Magnetic Fluid in Horizontal Field and Temperature Gradients
<p>In this work we studied the convective heat transfer in a magnetic fluid in both zero and applied magnetic fields. The natural convection is observed in a quasi-one dimensional magnetic fluid in a horizontal temperature gradient. The horizontal non-homogeneous magnetic fields were applied across …

Evaluation of an Early Classic Round Structure at Santa Rita Corozal, Belize
<p>Round structures in the Maya area are an architectural form that is not well understood, in part due to the relatively few examples recovered through archaeological excavations. The site of Santa Rita Corozal, Belize offers one of the few examples of an Early Classic Period round structure …

Layers of Identity & Privilege in Legislation: A Critical Discourse Analysis of Senate Bill 744
This research examines Senate Bill 744 (S.744) from the 113th Congress of the United States, and its findings will be used as a model to reveal problems in similar legislation. Senate Bill 744 was proposed by the 113th Congress in an attempt to accomplish bi-partisan immigration reform. The bill …

Exploring Social Identity through Stable Isotope Analysis in the Kellis 2 Cemetery
The material remains of ancient Egypt provide extensive and wide ranging data about the empire throughout its history. However, little evidence is available from ancient Egypt, or any past culture, with which to rebuild an image of social identity or individual experiences. This is especially …

Comparison of Second Order Conformal Symplectic Schemes with Linear Stability Analysis
Numerical methods for solving linearly damped Hamiltonian ordinary differential equations are analyzed and compared. The methods are constructed from the well-known Störmer-Verlet and implicit midpoint methods. The structure preservation properties of each method are shown analytically and …

Synthesis, Linear and Nonlinear Photophysical Characterization of Two Symmetrical Pyrene-terminated Squaraine Derivatives in Solution
Two indole-based squaraine dyes bonded to two pyrenyl groups through vinyl- and ethynyl- linkers were synthesized with the aim of enhancing the intramolecular charge transfer interaction in addition to improving their optical properties. The absorption and emission properties of these derivatives …

Integration of Multidimensional Signal Detection Theory with Fuzzy Signal Detection Theory
Signal detection theory (SDT) has proven to be a robust and useful statistical model for analyzing human performance in detection and decision making tasks. As with many models extensions have been proposed in order capture and represent the real world to a greater degree. Multidimensional Signal …

Propagation Failure in Discrete Inhomogeneous Medium Using a Caricature of the Cubic
Spatially discrete Nagumo equations have widespread physical applications, including modeling electrical impulses traveling through a demyelinated axon, an environment typical in multiple scle- rosis. We construct steady-state, single front solutions by employing a piecewise linear reaction term. …

It's a Conspiracy: Motivated Reasoning and Conspiracy Ideation in the Rejection of Climate Change
A large disconnect exists between the general public's acceptance of human-caused climate change and the prevailing consensus of actively publishing scientists. Previous research has examined both political and economic motivated reasoning, media influence in print and television, conspiracy …

The Effect of Precipitation on the Spread of Mosquito-Borne Diseases: A Case Study of Florida Counties
The state of Florida is the third most populous state in the United States of America, with six (6) of its metropolitan areas dubbed as the fastest growing in the entire country. A mosquito bite may mean the transmission of a virus or disease which might be fatal. Hence, there is a need for the …

Psychometric Issues Related to the Tinker Toy Test
An evaluation of executive functioning is a critical component of a comprehensive assessment of higher cerebral functioning. The Tinker Toy Test (TTT) was introduced in 1982. This test allows an individual to demonstrate the extent of their executive capacities by permitting them to initiate, plan, …
