This work describes the use of polyacrylamide hydrogels as controlled elastic modulus substrates for single cell traction force microscopy studies. The first section describes the use of EDC/NHS chemistry to convalently link microbeads to the hydrogel matrix for the purpose of performing long-term traction force studies (7 days). The final study…

Asphalt concrete pavements are inherently graded viscoelastic structures. Oxidative aging of asphalt binder and temperature cycling due to climatic conditions being the major cause of non-homogeneity. Current pavement analysis and simulation procedures dwell on the use of layered approach to account for these non-homogeneities. The conventional…

At the conclusion of the Spanish-American War of 1898, the United States purchased the Philippines from Spain in the Treaty of Paris. For over a decade beginning in early 1899, the United States waged a brutal war to suppress Filipinos seeking an end to colonial rule. My dissertation investigates the anti-imperialist movement in the United States…

This dissertation presents several studies designed to probe the mental representations that physics experts and novices form when interacting with typical instructional materials, such as diagrams and problem statements. By using recognition tasks and a change detection task, the mental representations of experts and novices are studied in a more…

This study sought to examine and comprehensively describe transfer students who have earned a two-year technical or occupational Associate in Science (AS) degree at the community college and entered the university to pursue the Bachelor of Science in Applied Science (BSAS).

This dissertation provides an automated scoring method of speech fluency for second language learners of English (L2 learners) based that uses speech recognition technology. Non-standard pronunciation, frequent disfluencies, faulty grammar, and inappropriate lexical choices are crucial characteristics of L2 learners' speech. Due to the ease of…

A modern space mission is assembled from multiple phases or events such as impulsive maneuvers, coast arcs, thrust arcs and planetary flybys. Traditionally, a mission planner would resort to intuition and experience to develop a sequence of events for the multiphase mission and to find the space trajectory that minimizes propellant use by solving…

This study deals with unplanned terminology development in the subject field of economics within media discourse. It examines how economic terms in Turkish newspapers emerge, are used, and cease. This developmental process is also analyzed through productivity of economic terms and the factors affect them. The subject terms are also analyzed as a…

Recent events of the Alabama Community College System are examined as an historical organizational case study. Critical events are noted along with associated professional literature related to those events and actions. While the study attempts to explain the organizational culture that allowed the rise of unethical leadership, the primary focus…

A fuzzy conjoint analysis (FCA: Turksen, 1992) model for enhancing management decision in the technology adoption domain was implemented as an extension to the UTAUT model (Venkatesh, Morris, Davis, & Davis, 2003). Additionally, a UTAUT-based Usage Intention Framework Model (UIFM) introduced a closed-loop feedback system. The empirical evidence…

The purpose of this qualitative study was to describe the ways in which Orisa priests and their clients conceptualize issues and concerns described by Western based approaches as mental health problems. The two research questions guiding this inquiry included: (a) how do Orisa priests and their clients conceptualize issues and concerns associated…

Effective poverty reduction programs require careful measurement of poverty status. Commonly used consumption or income-based classifications of poverty aggregate together households that are persistently poor with those who are only in poverty due to passing conditions. They also classify as non-poor households that are at risk of falling into…

Scope and method of study: Using the framework of Rogers's (1995) Diffusion of Innovation Theory, the purpose of the study is to examine the use of web-based instruction and faculty perceptions of web-based instruction in a Thai university. In this study, interviews with seven participants were used as the primary method to collect data.…

The purposes of this study were to (1) investigate non-accelerated middle schools students' understanding of pre-algebraic concepts, in particular, addition and subtraction of integers and the notion of equality; (2) describe and analyze how non-accelerated middle school students interact with The Geometer's Sketchpad (GSP) applets depicting…

Math skills are essential to daily life, impacting a person's ability to function at home, work, and in the community. Although reading has been the focus in recent years, many students struggle in math. The inability to master math calculation and problem solving has contributed to the rising incidence of student failure, referrals for special…
