Association Between Cognition and Depression: A Cross-Sectional and Longitudinal Study of Individuals with Learning Disabilities.

Description: Over the past twenty years the number of children identified with learning disabilities has risen drastically. In addition, 26 - 40% of these children also experience depression. While cognitive functioning has been demonstrated to be associated with depression, it is unclear whether the mood, vegetative, or cognitive symptoms of depression predict particular cognitive processes and vice versa. The purpose of this study was to determine which particular cognitive processes were associated with … more

An 8-Step Program: Shaping and Fixed-Time Food Delivery Effects on Several Approximations and Undesired Responses in Goats.

Description: This study investigated the effects of a shaping program for halter training across 8 steps in the program and 4 trial-terminating, or "undesirable," responses. Three La Mancha goats (Capra hircus) located at the Frank Buck Zoo in Gainesville, Texas were used for the study. A fixed-time 15 s (FT-15 s) was used during the baseline conditions, to examine the effects of response contingent and response-independent food deliveries, as well as to examine what preliminary steps might not necessarily … more

Stretched Out on Her Grave: Pathological Attitudes Toward Death in British Fiction 1788-1909

Description: Nineteenth-century British fiction is often dismissed as necrophillic or obsessed with death. While the label of necrophilia is an apt description of the fetishistic representations of dead women prevalent at the end of the century, it is too narrow to fit literature produced earlier in the century. This is not to say that abnormal attitudes toward death are only a feature of the late nineteenth century. In fact, pathological attitudes toward death abound in the literature, but the relationship… more

Study of Gate Electrode Materials on High K Dielectrics

Description: This problem in lieu of thesis report presents a study on gate electrode materials on high K dielectrics, including poly-SiGe and Ru. The stability of poly-SiGe in direct contact with Hf silicon-oxynitride (HfSiON) is studied by rapid thermal annealing (RTA), Rutherford backscattering spectrometry (RBS), X-ray photoelectron spectroscopy (XPS) and high resolution transmission electron microscopy (HRTEM). By performing a series of RTA treatments we found that as RTA thermal budgets reach 1050 C f… more

Improving Topic Tracking with Domain Chaining

Description: Topic Detection and Tracking (TDT) research has produced some successful statistical tracking systems. While lexical chaining, a non-statistical approach, has also been applied to the task of tracking by Carthy and Stokes for the 2001 TDT evaluation, an efficient tracking system based on this technology has yet to be developed. In thesis we investigate two new techniques which can improve Carthy's original design. First, at the core of our system is a semantic domain chainer. This chainer relie… more

The Impact of Financial Aid on Persistence: Application of the Financial Nexus Model

Description: The purpose of this study was to examine the financial nexus between college choice and persistence for full-time, first-time, first-year freshman college students. The theoretical framework of this study was the financial nexus construct developed by St. John, Paulsen, and Starkey (1996) and Paulsen and St. John (1997). This is the first study to apply the financial nexus construct to full-time, first-time, first-year freshman population; the first to examine baccalaureate/comprehensive and do… more

Cognitive Differences Between Congenitally and Adventitiously Blind Individuals.

Description: It is apparent from the historical perspective regarding the theories of cognitive development and the cognitive functioning of individuals with visual impairments, that sight plays a major role in the development of certain cognitive processes. However, the affects of visual impairment on cognitive development remain to be at issue. Since sight seems to be highly integral in cognitive development beginning in the early stages of physical development, about the sixth month of life, and then beg… more

Why the Japanese double-ga construction cannot be scrambled.

Description: This thesis presents a comprehensive study of the Japanese double-ga construction and offers an explanation as to why the Japanese double-ga construction does not allow scrambling. In chapter 2, the particle-ga and the particle-wa are defined as the focus marker and the topic marker respectively. The different shades of meaning that both particles have are also explained. Chapter 3 illustrates the Japanese double -ga construction. Chapter 4 deals with the impossibility of scrambling in the doub… more

Applications of Remote Sensing and GIS to Modeling Fire for Vegetative Restoration in Northern Arizona

Description: An accurate fire model is a useful tool in predicting the behavior of a prescribed fire. Simulation of fire requires an extensive amount of data and can be accomplished best using GIS applications. This paper demonstrates integrative procedures of using of ArcGIS™, ERDAS Imagine™, GPS, and FARSITE© to predict prescribed fire behavior on the Kaibab-Paiute Reservation. ArcGIS was used to create a database incorporating all variables into a common spatial reference system and format for the FARSIT… more

Synthesis of Polycyclic Natural Products

Description: With the continuous advancements in molecular biology and modern medicine, organic synthesis has become vital to the support and extension of those discoveries. The isolations of new natural products allow for the understanding of their biological activities and therapeutic value. Organic synthesis is employed to aid in the determination of the relationship between structure and function of these natural products. The development of synthetic methodologies in the course of total syntheses is im… more

A Comparison of Agent-Oriented Software Engineering Frameworks and Methodologies

Description: Agent-oriented software engineering (AOSE) covers issues on developing systems with software agents. There are many techniques, mostly agent-oriented and object-oriented, ready to be chosen as building blocks to create agent-based systems. There have been several AOSE methodologies proposed intending to show engineers guidelines on how these elements are constituted in having agents achieve the overall system goals. Although these solutions are promising, most of them are designed in ad-hoc man… more

Social Discourse in the Savoy Theatre's Productions of The Nautch Girl (1891) and Utopia Limited (1893): Exoticism and Victorian Self-Reflection

Description: As a consequence to Gilbert and Sullivan's famed Carpet Quarrel, two operettas with decidedly "exotic" themes, The Nautch Girl; or, The Rajah of Chutneypore, and Utopia Limited; or, The Flowers of Progress were presented to London audiences. Neither has been accepted as part of the larger Savoy canon. This thesis considers the conspicuous business atmosphere of their originally performed contexts to understand why this situation arose. Critical social theory makes it possible to read the two … more

Resource Allocation in Mobile and Wireless Networks

Description: The resources (memory, power and bandwidth) are limited in wireless and mobile networks. Previous research has shown that the quality of service (QoS) of the mobile client can be improved through efficient resources management. This thesis contains two areas of research that are strongly interrelated. In the first area of research, we extended the MoSync Algorithm, a network application layer media synchronization algorithm, to allow play-out of multimedia packets by the base station upon the m… more
