The purpose of this research was to determine if installing a smaller air compressor could reduce the electrical usage of a large semiconductor manufacturing plant. A 200 horsepower Atlas Copco compressor was installed with the existing 500 horsepower Ingersoll-Rand compressors. Testing was conducted during the regular manufacturing process at MEMC Southwest in Sherman, Texas. Analysis of the data found that installing the new compressor could reduce electrical consumption. The study also found there are specific operational setpoints that allow the compressor to operate more efficiently.

Competition to lure corporations has become an enormous issue between states. Smaller communities feel unable to participate in economic development opportunities since their budgets do not provide the necessary funding. In 1979, the Texas state legislature passed the Development Corporation Act in an attempt to aid the smaller communities' quest for economic development. The Act allowed for the creation of local development corporations; however, it did not provide a sufficient funding source to assist the corporations. Therefore two local sales options were established. This paper reports the findings of an analysis of per capita income and employment changes after the adoption of an economic development sales tax. The analysis showed no statistically significant impacts on cities adopting an economic development sales tax when compared with non-adopting cities.

Automatic memory management is crucial in implementation of runtime systems even though it induces a significant computational overhead. In this thesis I explore the use of statistical properties of the directed graph describing the set of live data to decide between garbage collection and heap expansion in a memory management algorithm combining the dynamic array represented heaps with a mark and sweep garbage collector to enhance its performance. The sampling method predicting the density and the distribution of useful data is implemented as a partial marking algorithm. The algorithm randomly marks the nodes of the directed graph representing the live data at different depths with a variable probability factor p. Using the information gathered by the partial marking algorithm in the current step and the knowledge gathered in the previous iterations, the proposed empirical formula predicts with reasonable accuracy the density of live nodes on the heap, to decide between garbage collection and heap expansion. The resulting heuristics are tested empirically and shown to improve overall execution performance significantly in the context of the Jinni Prolog compiler's runtime system.

This work is an exploration into the palindrome, both as a literary form and an expression of infinity. The first two chapters address the fascinating manner in which the mind contextualizes fragments of speech and ludicrous grammatical implications that are spawned by the poetic structure of the palindrome (third chapter). The thesis then departs from the literary aspect of the palindrome and focuses in the fourth chapter on structural likenesses in psychology and mythology. The fifth chapter argues the palindrome and parallel conceptual structures as examples of recursion, then presents examples of recursion in language/grammar, art, and computer science. The sixth chapter uses instances of the recursive equiangular spiral throughout nature to introduce recursion and therefore the palindrome as an archetypal expression of infinity. The thesis ends with a list of the author's palindromes.

The purpose of this study was to examine the effects frequenting the street had on the social-emotional development of children in Cuenca, Ecuador. While the study sought to discover who these children were, it primarily observed the levels of trust these children felt in the various contexts of their lives, their level of safety, where they saw themselves in the future, what made a place feel like a home, their sense of self-esteem, and how they saw themselves contributing to their future. The research instrument used in this study was a modified youth questionnaire previously developed by Tyler and Tyler (1991) in a study with street children/youth in Bogóta, Colombia. The results are presented in 11 case studies of children who ranged in age between 7 and 12 years.

The medium of language is important to environmental philosophy, and more specifically, to the establishment and understanding of environmental relationships. The differences between animal and human language point to our unique semantic range, which results from our neuro-linguistic process of signification. An examination of the linguistic implications of the problem of nature and the tenets of semiotics challenges the idea of a clean word to world fit. Because signs are the medium in which meaning is constructed, questions about nature must in part be questions of language. Environmental discourse itself is bound up in sociolinguistic productions and we must attend not only to what language says, but to what it does. NEPA functions as a speech act that systematically invokes an ethical framework by which it colonizes the domain of valuation and fails to provide a genuine opportunity for non-commodity values to be expressed.

Through this body of work and this paper the possibilities of using Fashion Design to express the concepts of the circle has been explored. This was done with three questions in mind: How can I use the shape of the circle as inspiration for fashion design? How can I express related words and phrases in my design? and How can I use the colors black and white to emphasize the concept of my design. To answer these questions I have created two groups of garments: one was inspired by circular objects, such as cherries and drops, and the other starting from words and phrases such as "study circle" and "circle the wagons." In the first group the emphasis was on the aesthetics of the garment while the second group was more focused on meaning. All garments are black and white.

The kinetics of the pressure dependent O + SO2 + Ar reaction have been investigated using laser photolysis resonance fluorescence at temperatures of 289 K, 399 K, 581 K, 699 K, 842 K and 1040 K and at pressures from 30-665 torr. Falloff was observed for the first time in the pressure dependence. Application of Lindemann theory yielded an Arrhenius expression of k(T) = 3.3 x 10-32exp(-992/T) cm6 molecule-1 s-1 for the low pressure limit and k(T) = 8.47 x 10-14exp(-468/T) cm3 molecule-1 s-1 for the high pressure limit at temperatures between 289 and 842 K. The reaction is unusual as it possesses a positive activation energy at low temperature, yet at higher temperatures the activation energy is negative, illustrating a reaction barrier.

The Lewisville Lake Environmental Learning Area (LLELA) is a wildlife management area with tallgrass prairie, an endangered ecosystem. Essential ecosystem processes, especially fire, are part of restoration. To support fire management efforts at LLELA and surrounding areas, this project evaluated and developed tools for fire restoration. The four primary prairie grasses respond favorably to burning. Fuel loads and fuel models vary by scale and survey method. One- and 10-hour fuel moisture can be predicted using a statistical model; 100- and 1,000-hour fuel moisture cannot. Historic weather data suggests that burning can occur when it is most effective. The production of ozone precursors produced by burning is comparable to those emitted every six minutes by regional automobiles.

Teacher attrition is a problem with a number of implications, not the least of which is the teacher shortage. Almost half of all new teachers leave the profession within the first five years, creating a difficult model where more teachers leave the teaching profession compared to teachers entering the profession. Part of the problem is a result of career progression. However, most of teacher attrition is a result of factors such as inadequate pay, administrative support, workplace conditions, student related issues, and collegiality with peers. Without a thorough understanding of the factors that contribute to teacher attrition it is impossible to create an environment where "No Child is Left Behind". Although teachers do not enter the profession with the notion of getting rich, they do need to make enough money to support themselves and their families. Furthermore, professional status in America is closely tied to socioeconomic status. Therefore, while salary may be the largest component of teacher attrition, school and district characteristics, teacher qualifications, and demographics also affect a teacher's decision to leave the profession.

This written thesis is a companion to a 30-minute documentary video of the same title. The documentary is a presentation of the historical conflict between the United States Navy and the people of the island of Vieques, Puerto Rico. For over 60 years the island was used by the United States Navy as a military training facility. The documentary attempts to present an analysis of the struggle between citizens of the island and the Navy. This written component presents a summarized history of Puerto Rico, Vieques and the conflict with the United States Navy. In addition, the preproduction, production and post-production process of the documentary are discussed. A theoretical analysis of the filmmaker's approach and technique are addressed and analyzed as well. The thesis's goal is to provide a clear understanding of the Vieques conflict to United States audiences who do not a familiarity with the topic. The thesis is presented from the perspective of a person who grew up in Puerto Rico.

The purpose of this study was to determine whether coaching behavior preferences of NCAA Division I athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnare (CBQ; Martin & Barnes, 1999) was administered to 195 NCAA Division I athletes. Gender and sport type were the independent variables and the participant's mean scores for the subscales on the CBQ were the dependent variables. Descriptive statistics revealed that, overall, NCAA Division I athletes prefer positive and instructional behaviors more than non-responses or negative behaviors. A 2 (gender) x 3 (type of sport) MANOVA and follow-up discriminant function analysis indicated that coaching behavior preferences differed as a function of gender and type of sport played. Thus, NCAA Division I coaches should consider both individual and situational characteristics when working with their athletes to achieve the desired outcome.

The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL™ database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.

The early music ensemble has evolved from a counterculture to a mainstream musical genre. Because of this early music is having to learn arts management. Once a unique force it now competes with other arts organizations for funding and audience. Unlike other arts groups, early music has little help from within to clarify non-profit management. Through three types of surveys that were e-mailed to 239 early music organizations and 20 early music societies, an assessment of what is currently happening with early music ensembles in terms of growth, funding and over all well-being can be made. The information obtained revealed that most early music ensembles have little or no training in how to run an organization. This inexperience is creating problems and changing the face of early music. Information from the surveys also reveals that even with the economic problems over the last three years, early music is continuing to survive.

This study examines the effects of two teaching procedures and two testing procedures (“Skip” and “Guess”) on acquisition, retention and generalization of learning. Three typically developing females between the ages of 8 and 11 learned the 24 lower case letters of the Greek alphabet. Half of the letters were taught with the “Skip” procedure and the other half with the “Guess” procedure. The “Skip” procedure produced faster and more efficient learning than the “Guess” procedure. The “Skip” procedure also resulted in better initial retention (4 weeks), but this effect disappeared in subsequent retention tests. The training conditions did not have differential effects on generalization tests across learning channels, except for the Free/Say channel.

The purpose of this study was threefold: (a) to examine the separate effects of increased accuracy on multiple-choice/rank-order written tests and coaching on the teaching performance of participants; (b) to compare generalization across tasks produced by the workshop and coaching; and (c) to assess maintenance of teaching performance. Following baseline, two adults received a lecture on discrete trial teaching procedures. A written test measured verbal performance on workshop material periodically throughout this phase. During the next phase, each adult then experienced further training via in-situ coaching. A multiple baseline design across tasks was used during the coaching phase. Results of the workshop training package revealed an inverse relationship between the strongest verbal performance and strongest teaching performance skill areas. In addition, only with the introduction of the in-situ coaching package did teacher performance improve significantly across all behaviors. Child responding remained relatively constant throughout the study, regardless of teacher performance. Some generalization of teacher behavior was observed across tasks, but was extremely variable across both workshop and coaching conditions. After the cessation of coaching, teacher performance remained stable across maintenance phases and at a 6-week follow-up.

This thesis uses the work and career of the textile designer Maria Kipp to stage a prolegomena concerning how to write about a female designer active during the middle of the twentieth century. How can design historians incorporate new methodologies in the writing of design history? This thesis explores the current literature of feminist design history for solutions to the potential problems of the traditional biography and applies these to the work and career of Kipp. It generates questions concerning the application of methodologies, specifically looking at a biographical methodology and new methodologies proposed by feminist design historians. Feminist writers encourage scholarship on unknown designers, while also they call for a different kind of writing and methodology. The goal of this thesis is to examine how these new histories are written and in what ways they might inspire the writing of Kipp into design history.

On-line Analytical Processing (OLAP) cube is designed using Microsoft® Analysis Server.

During World War II, Lee Miller was an accredited war correspondent for Vogue magazine. Miller was trained as a surrealist photographer by Man Ray, and her wartime work, both photographic and written, is indicative of a combination of journalism and surrealism. This thesis examines Lee Miller's war correspondence within the context of Vogue magazine, establishing parallels between the photographs and writing to determine how surrealism informs it stylistically and ideologically. Using surrealist techniques of juxtaposition and an unmanipulated photographic style, and the surrealist concepts of the Marvelous and Convulsive Beauty, Miller presented the war as a surreality, or a surreal reality. This study concludes by using Miller's approach to suggest a new concept of journalistic practice: surrealist journalism.

With the growing popularity of e-commerce applications that use software agents, the protection of mobile agent data has become imperative. To that end, the performance of four methods that protect the data integrity of mobile agents is evaluated. The methods investigated include existing approaches known as the Partial Result Authentication Codes, Hash Chaining, and Set Authentication Code methods, and a technique of our own design, called the Modified Set Authentication Code method, which addresses the limitations of the Set Authentication Code method. The experiments were run using the DADS agent system (developed at the Network Research Laboratory at UNT), for which a Data Integrity Module was designed. The experimental results show that our Modified Set Authentication Code technique performed comparably to the Set Authentication Code method.

Voluntary turnover has become a problem for many organizations in today's society. The cost of this turnover reaches beyond organizational impact, but also affects the employees themselves. For this reason, there has been a plethora of research conducted by both academicians and practitioners on the causes and consequences of voluntary turnover. The purpose of this study is to test the validity and generalizability of the job embeddedness model of voluntary turnover to the information technology (IT) industry. The IT field has been plagued with high turnover rates in recent years. In this study, the job embeddedness model (Mitchell et al., 2001) is applied to a population sample consisting of health care information technology employees.

Finite functions (also called maps) are used to describe a number of key computations and storage mechanisms used in software and hardware interpreters. Their presence spread over various memory and speed hierarchies in hardware and through various optimization processes (algorithmic and compilation based) in software, suggests encapsulating dynamic size changes and representation optimizations in a unique abstraction to be used across traditional computation mechanisms. We developed a memory allocator for testing the finite functions. We have implemented some dynamic finite functions and performed certain experiments to see the performance speed of these finite functions. We have developed some simple but powerful application programming interfaces (API) for these finite functions.

The body of work created during this exploration indicates that painting approach can actively integrate with the clay element. The main point is the surface manipulation during this process. There are four factors relate to this manipulation: timing, action, style, and size. Overall, the painting approach can be modified to create a truly active relationship with clay element. The final touch by the fire and glazing techniques reflect paintings approach may be used in a variety way to decorate the clay element without any limits. Moreover, the painting approach need not be subordinate to the clay element. It can be used not only to complement the clay, but also to enhance any given clay pieces no matter what the shape is.

Library information systems use different software applications and automated systems to gain access to distributed information. Rapid application development, changes made to existing software applications and development of new software on different platforms can make it difficult for library information systems to interoperate. Web services are used to offer better information access and retrieval solutions and hence make it more cost effective for libraries. This research focuses on how web services are implemented with the standard protocols like SOAP, WSDL and UDDI using different programming languages and platforms to achieve interoperability for libraries. It also shows how libraries can make use of this new technology. Since web services built on different platforms can interact with each other, libraries can access information with more efficiency and flexibility.
