Children who grow up in poverty are more likely to be exposed to prolonged and cumulative stress, which can lead to several risk factors (Fraser, Kirby, & Smokowski, 2004; Garmezy, 1993). They are more likely to have negative life outcomes such as poor academic achievement, lack of a sustained familial support structure, emotional distress, and behavioral struggles (Fra....

This dissertation documents the ways in which cartography was used during the Scramble for Africa to conceptualize, conquer and administer newly-won European colonies. By comparing the actions of two colonial powers, Germany and Britain, this study exposes how cartography was a constant in the colonial process. Using a three-tiered model of “gazes” (Discoverer, Desp....

In this research, we develop innovative regression models for survival analysis that model time to event data using a latent health process which stabilizes around an equilibrium point; a characteristic often observed in biological systems. Regression modeling in survival analysis is typically accomplished using Cox regression, which requires the assumption of proportio....

Our research group is focused on developing novel cavitands – gated molecular baskets and understanding their mechanism of action. These dynamic hosts comprise a bowl-shaped platform with a set of three aromatic gates revolving at the rim of the cavity and thereby controlling the encapsulation kinetics. We have shown that gated baskets are capable of promoting selecti....

Teaching a child to read is one of the greatest gifts we can give to that individual and to society as a whole, and yet many students exit school without the necessary literacy skills. For decades, research has demonstrated the importance of phonemic awareness in the development of the alphabetic principle, a prerequisite for competent reading, along with laying the fou....

Ab initio quantum chemical calculations and ultrafast time-resolved laser flash photolysis techniques have been used to study nitrenes and carbenes generated from the photoexcitation of the corresponding precursors. The photophysics and photochemistry of 3-ethyl-3-methyldiazirine were investigated using high-level quantum chemistry calculations. The denitrogenation of ....

Vibration control is a critical function of the bar feeders which are used to automatically feed stock to high-volume computer-numeric-controlled turning operations. Current technology employs continuous rigid support along the length of the bar; however, the need to quickly load fresh bar stock and change between stock sizes makes the physical implementation cumbersome....

Mothers with chronically ill children face the double burden of caregiving and employment to maintain and improve family financial well-being. This research aims to investigate the labor market behavior of mothers in response to the financial and time burden of caring for children with chronic conditions. An instrumental variable approach is used to deal with the potent....

This dissertation offers a reevaluation of a long-standing model for the early history of the Roman Republic. Modern scholars have generally believed that the Roman plebs in the first two centuries of the Republic (roughly the fifth and fourth centuries B.C.) was essentially a revolutionary political organization, dedicated to increasing the rights and opportunities of ....

Shakespeare wrote his plays for performance. More specifically, Shakespeare wrote his plays to be performed according to a particular set of practices by which authorial manuscripts were sundered into parts, distributed in pieces to players for private study, and reassembled in as few rehearsals as possible. Private study included the memorization of speeches and cues, ....

Ample evidence suggests that young people with autism spectrum disorders (ASDs) present with a wide range of maladaptive behaviors beyond the core symptoms that define the disorder. Such maladaptive behaviors represent additional handicaps for these individuals and are associated with negative outcomes including poor social competency, academic and vocational under-achi....
