This paper is a contribution to the study of countable Borel equivalence relations on standard Borel spaces. We concentrate here on the study of the nature of translation equivalence. We study these known hyperfinite spaces in order to gain insight into the approach necessary to classify certain variables as either being hyperfinite or not. In Chapter 1, we will give the basic definitions and examples of spaces used in this work. The general construction of marker sets is developed in this work. These marker sets are used to develop several invariant tilings of the equivalence classes of specific variables . Some properties that are equivalent to hyperfiniteness in the certain space are also developed. Lastly, we will give the new result that there is a continuous injective embedding from certain defined variables.

My thesis focuses on philosophical themes implicit in corridor conservation, using the Big Thicket National Preserve as an example. The way in which corridors, boundaries and communities are ambiguous, as both limits and connections, is dealt with. Corridor-patch matrices assemble ecological and human groups into temporary communities, often with conflicting interests. Such constellations foreground how a foreigner's boundary crossing is a notion important to both conservation and a philosophical study of being, seen as being always in relation with otherness. In this context, the notion of foreignness and Jean-Luc Nancy's idea of being-with is explored. Understanding the complex network of relations in which an entity exists leads to an awareness of its ambiguous nature. To facilitate judgment with such ambiguity, one needs a contextual understanding of a situation.

The proposed study examined differences in self-concept between ADHD (n = 61) and non-ADHD boys and girls. Participants included 108 children between 6 and 11 years old. Children completed the Self Description Questionnaire-I, and teacher reports of child competence were obtained. Girls reported lower physical ability and mathematics self-concept than boys. The results also indicated that ADHD girls may be more susceptible to low physical ability and mathematics self-concept than control children or ADHD boys. Teachers also rated ADHD girls as having lower scholastic competence than the other three groups. Teachers reported significant differences in level of competence based on ADHD status. The implications of the current study and directions for future research will be presented.

This study documents and analyzes cyclic patterns used as melodic vocabulary in John Coltrane's improvisations from compositions of 1965 to 1967. The analysis is categorized in two distinct sections. The first section analyzes melodic vocabulary that is derived from the cycle of descending major thirds progressions found in the compositions of 1959 to 1960. The second section analyzes melodic vocabulary that is derived from Nicolas Slonimsky's Thesaurus of Scales and Melodic Patterns using the theoretical terminology incorporated in the treatise. Musical examples consist of patterns from the Thesaurus and excerpts from selected improvisations of John Coltrane as transcribed by Andrew White. Important scholarly contributions relevant to the subject by Carl Woideck, Lewis Porter, David Demsey, and Walt Weiskopf are included. Every effort has been made to cite interviews with musicians and commentaries by writers contemporary to that period of time with special emphasis on the important influence of Thelonious Monk, Miles Davis, and Ornette Coleman. Chapter headings include: Literature Review and Methodology; Thelonious Monk, Miles Davis, and Ornette Coleman: Converging Influences; Analysis: Coltrane's Major Thirds Harmonic Cycles Used as Melodic Vocabulary; Interval Cycles in Coltrane's Melodic Vocabulary Based on Patterns from Slonimsky's Thesaurus; Summary and Conclusion.

For many years mathematicians have been interested in the problem of whether an operator ideal is complemented in the space of all bounded linear operators. In this dissertation the complementation of various classes of operators in the space of all bounded linear operators is considered. This paper begins with a preliminary discussion of linear bounded operators as well as operator ideals. Let L(X, Y ) be a Banach space of all bounded linear operator between Banach spaces X and Y , K(X, Y ) be the space of all compact operators, and W(X, Y ) be the space of all weakly compact operators. We denote space all operator ideals by O.

Several interpretations in performances, recordings, and publications of Giuseppe Verdi's Messa da Requiem raise issues concerning the relationship between these readings and the composer's intention. Understanding Verdi's tempo and phrasing in the Requiem is of crucial importance in rediscovering his intention. Knowing that Verdi's metronome markings were not merely performance suggestions but that they actually reflected his final decision is equally important. Unlike his operas, fast tempos are not introduced suddenly in the Requiem; rather, where tempo changes occur gradually from one section to the next, thereby maintaining the music's overall character. Verdi's phrasing is very subtle, and unconventional, because one sign may have multiple meanings. Compounding this complication are the many editorial errors in the published editions. David Rosen, in his critical edition, corrected many of these errors, and made additional editorial suggestions, but there are still numerous places where determining correct phrasing, as well as tempo fluctuations, knowledge of Verdi's use of signs and symbols is difficult.

In the field of information sciences, attention has been focused on developing mature information retrieval systems that abstract information automatically from the contents of information resources, such as books, images and films. As a subset of information retrieval research, content-based image retrieval systems automatically abstract elementary information from images in terms of colors, shapes, and texture. Color is the most commonly used in similarity measurement for content-based image retrieval systems. Human-computer interface design and image retrieval methods benefit from studies based on the understanding of their potential users. Today's children are exposed to digital technology at a very young age, and they will be the major technology users in five to ten years. This study focuses on children's color perception and color association with a controlled set of digital images. The method of survey research was used to gather data for this exploratory study about children's color association from a children's population, third to sixth graders. An online questionnaire with fifteen images was used to collect quantitative data of children's color selections. Face-to-face interviews investigated the rationale and factors affecting the color choices and children's interpretation of the images. The findings in this study indicate that the color children associated …

Technology has a profound influence on how business, education, entertainment, and interpersonal communications are conducted. Mental health professionals have been exploring how technology can support and enhance client care since the 1960s. In the last decade the influence of technology in the practice of counseling has increased dramatically. As the use of technology increased, so did the expectations for counselor preparation programs to include technology instruction. In 1999, the Association for Counselor Education and Supervision (ACES) developed the Technical Competencies for Counselor Education Students: Recommended Guidelines for Program Development. This study examines the technological competence of counseling students at one southwestern university based on the ACES recommendations.

Through my work, I explored the application of texture and materials as a means to identify specific functions. I show how texture and material selections that specifically engage the sense of touch can aid in effective environments for the elderly. By means of this study, I demonstrated how the sensory perception of the elderly is utilized in designing productive environments for the senior population in regards to the sense of touch. The interior design of senior living environments can greatly enhance the retirement experience for the elderly population. With the information I have gained through my research and work will reflect in my future design projects. I also wish to share this enlightenment with others in my field of study.

Wireless ad hoc networks are expected to play an important role in civilian and military settings where wireless access to wired backbone is either ineffective or impossible. Wireless sensor networks are effective in remote data acquisition. Congestion control and power consumption in wireless ad hoc networks have received a lot of attention in recent research. Several algorithms have been proposed to reduce congestion and power consumption in wireless ad hoc and sensor networks. In this thesis, we focus upon two schemes, which deal with congestion control and power consumption issues. This thesis consists of two parts. In the first part, we describe a randomization scheme for congestion control in dynamic source routing protocol, which we refer to as RDSR. We also study a randomization scheme for GDSR protocol, a GPS optimized variant of DSR. We discuss RDSR and RGDSR implementations and present extensive simulation experiments to study their performance. Our results indicate that both RGDSR and RDSR protocols outperform their non-randomized counterparts by decreasing the number of route query packets. Furthermore, a probabilistic congestion control scheme based on local tuning of routing protocol parameters is shown to be feasible. In the second part we present a simulation based performance study …

In this study, the supportive nature of the parent-child relationship was examined for how it relates to young adults' romantic development, as measured by indicators of attachment relationship importance and romantic involvement. Attachment and social support theories suggest that parents continue to play an important role as their young adult children form romantic relationships. Prior research has indicated that perceived support from parents is positively related to young adults' expressing attachment relationship importance, as evidenced by attachment motivation and engaging in exploration about romantic relationship topics. Furthermore, support from parents has been negatively related to romantic and sexual involvement. Therefore, it was believed that support in the parent-child relationship would predict both the indicators of attachment relationship importance and the indicators of romantic involvement in the present study. Additionally, an interaction of parental support and participants' gender was expected for the indicators of attachment relationship importance but not romantic involvement. A sample of 157 women and 144 men, ages 18-22 completed questionnaires. These measures assessed the supportive quality of relationships with each parent and indicators of the young adults' romantic development. For the indicators of attachment relationship importance, results indicated that exploration was predicted by gender and a conflictual relationship …

The purpose of the study was to describe a family literacy program attempting to teach adult English language learners (ELL) the knowledge and skills that would allow them to support their children's learning at home. The methodology employed was a multi-case study. Fourteen adult participants were interviewed to gather information regarding the factors that influenced the adult participant's ability to support their child's learning prior to participation in the family literacy program. The study focused on the knowledge, skills and attitudes acquired in the literacy program and used to support their child's learning at home and the curriculum and instruction that the participants used to influence their child's learning. The methodology used to gather information included adult English language learner interviews, field observations, and contact analysis of lesson plans. The following conclusions were derived based on analysis of the data: 1. In the family literacy program that was studied, the only prior factor that appeared to influence the parent's ability to support their child's learning was the education level of the participant. 2. Pronunciation, conversation, listening, grammar and writing are are essential skills that ELL parents use to support their child's learning. Attitudes were directly affected by the participants' ability …

Storm water quality can have a significant impact on receiving water bodies. The chief recipients of these impacts are aquatic life in the receiving water body and downstream water users. Over the last few decades, legislation, regulations, institutions and facilities have evolved to recognize the impact of urban storm water on receiving streams. This increased emphasis has caused contaminants in storm water to be identified as a major concern. This developing concern has generated an increased interest in the water quality of our streams and lakes and emphasized the need for more monitoring efforts. With the passage of the National Pollutant Discharge Elimination System (NPDES) Phase II requirements, small municipalities are responsible for storm water impacts on receiving waters within their jurisdiction. For the purposes of NPDES Phase II requirements, small municipalities are identified as these municipalities that are typically composed of 10,000 but less than 100,000 in population. The purpose of this dissertation is to develop a manual for use by the staff of small municipalities in meeting the requirements prescribed by changes initiated in the NPDES Phase II regulations. Attempts were made to comply with these requirements within a very limited manpower and budget framework and to develop …

This study sought to identify pre- and post-matriculation characteristics of undergraduate Hispanic students at the University of North Texas (UNT). The study also examined demographic trends among this population. Eleven purposes guided the study: 1) to determine geographic origins of the undergraduate Hispanic students at UNT in terms of location of educational institution attended prior to matriculation; 2) to establish whether students entered UNT as true freshmen or transfer students; 3) to ascertain the gender composition of undergraduate Hispanic students at UNT; 4) to report the highest level of education achieved by parents of undergraduate Hispanic students at UNT; 5) to explore patterns in major selection of undergraduate Hispanic students at UNT and who or what influenced that choice of major; 6) to ascertain the percentage of undergraduate Hispanic students at UNT who plan to use financial aid during their enrollment; 7) to examine the graduation rates among undergraduate Hispanic students at UNT; 8) to determine who is most influential in the academic decisions made by Hispanic undergraduate students at UNT; 9) to discover what type of emotional support is given to Hispanic students pertaining to their college enrollment and success; 10) to establish why Hispanic undergraduate students elect to …

The present study compared the responses of a group of simulating malingerers who were offered a monetary incentive to feign symptoms of a head injury, with the responses of head injured groups both with and without litigation, a forensic parole group, and an honest-responding control group. The following six neuropsychological measures were utilized: Rey 15-Item Memory Test, Controlled Oral Word Association Test, Finger Oscillation Test, WAIS-R Neuropsychological Instrument (Vocabulary, Information, and Similarities subtests), Booklet Category Test, and Wisconsin Card Sorting Test. The statistical concepts of floor effect, performance curve, and magnitude of error were examined. Additionally, the statistical differences in the responses of the five groups were analyzed to determine cutting scores for use in distinguishing malingerers from nonmalingerers.

California legislated the restructuring of its electric power industry in 1996. Deregulation was successful until 2000 when crisis, caused by a number of outside forces and flawed legislation, sent wholesale electric prices skyrocketing. Restructuring of the electricity sector in Texas occurred in two phases. The first phase began in 1995, when wholesale markets were opened to competition; the second phase began June 18, 1997, when the 1999 Texas Electric Choice Act, was signed into law. Deregulation has largely been successful in Texas. This analysis examines the legislation of these states and how they differed, setting the stage for one unsuccessful and one successful move to retail competition in the electricity industry.

The increasing awareness of data mining technology, along with the attendant increase in the capturing, warehousing, and utilization of historical data to support evidence-based decision making, is leading many organizations to recognize that the effective use of data is the key element in the next generation of client-server enterprise information technology. The concept of data mining is gaining acceptance in business as a means of seeking higher profits and lower costs. To deploy data mining projects successfully, organizations need to know the key factors for successful data mining. Implementing emerging information systems (IS) can be risky if the critical success factors (CSFs) have been researched insufficiently or documented inadequately. While numerous studies have listed the advantages and described the data mining process, there is little research on the success factors of data mining. This dissertation identifies CSFs in data mining projects. Chapter 1 introduces the history of the data mining process and states the problems, purposes, and significances of this dissertation. Chapter 2 reviews the literature, discusses general concepts of data mining and data mining project contexts, and reviews general concepts of CSF methodologies. It also describes the identification process for the various CSFs used to develop the research framework. …

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 specific depressive symptoms and depression as a whole. Structural equation modeling (SEM) was conducted to test a model which examined how three cognitive processing factors (verbal & visual reasoning, and attention/working memory) were associated with three depressive symptom factors (disturbances in mood, vegetative, and cognitive functioning). The data for SEM came from a large data set of children with learning disabilities (n=227). Model fit results supported the proposed model, and a significant association was found between the attention/working memory factor and the depression symptom factor reflecting disturbances in cognitive functioning. Less robust relationships were observed between verbal reasoning and cognitive depressive symptoms and an approach toward the conventional level of significance was noted between visual reasoning and cognitive depressive symptoms. Using a sub-sample of original participants who were …

The study analyzed how parenting stress and discouragement affect stepfamily functioning. Whether the parent was a biological parent or stepparent, whether the stepparent was a stepmother or stepfather, or whether the marriage had been formed more or less than two years was also considered. One assumption made was that increased parenting stress and discouragement will lead to decreased family functioning. Other assumptions were that there will be more increased parenting stress and discouragement and decreased family functioning found in stepparents than biological parents, in stepmothers more than stepfathers, and in parents in families formed less than two years more than those in families formed more than two years. Complete data was collected from 30 subjects. Three instruments were used in the study. The Parenting Stress Index measures how much stress parents experience in areas relating to how they see their child and how they see themselves as parents. The Discouragement Scale for Adults was developed to measure the Adlerian concept of discouragement in an adult population. The Family Assessment Device measures how a family functions.

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 between the deceased and the survivor is not always sexual in nature. Rather, there is a clear shift in attitudes, from the chaste death fantasy, or attraction to the idea of death, prevalent in Gothic works, to the destructive, stagnant mourning visible in mid-century texts, and culminating in the perverse sexualization of dead women at the turn of the century. This literary shift is most likely attributable to the concurrent changes in attitudes toward sex and death. As sex became more acceptable, more public, via the channels of scientific discourse, death became a less acceptable idea. This “denial of death” is a direct reaction to the religious uncertainties brought about by industrialization. As scientists and industrialists uncovered increasing evidence against a …

Over the last decade there has been a rapid development of United States quick service restaurant companies such as KFC and McDonalds in China. Increasingly urban Chinese consumers patronize these restaurants as a way to experience American culture. For some it is becoming a part of their eating pattern. Recent health studies have demonstrated that nutritional diseases are increasing in China. This study accessed urban Chinese consumers' perceptions about U.S. quick service restaurants and their knowledge about the nutritional value that U.S. quick service food can provide. This study revealed that Chinese consumers' perceptions and knowledge about U.S. quick service impacts their patronage. Additionally, the study determined correlation between consumer patronage and reported health status as well as consumers' length of patronage negative influence on their health status. The results of this study will help U.S. quick service restaurants in educating consumers on nutrition and improving the menus.

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 for 30s, the poly-SiGe layer begins to intermix with the HfSiON film, as observed by TEM. The maximum annealing condition for the Hf0.14Si0.23O0.46N0.17 film to remain stable in contact with poly-SiGe is 1050 C for 20s in high purity N2(99.9%) ambient. We also found that after 1000 C annealing for 60s in a nitrogen ambient, the poly-SiGe crystal phase structure was changed from a columnar structure to a large grain structure. For a metal gate, Ru was studied to determine N2annealing effects on sheet resistance of Ru sample electrodes and electrical characterization of Ru/HfSiOx/Si stack. Results show that a pure Ru metal gate is not a good choice for high k materials since it is hard to etch off, and different annealing conditions can cause large changes in …

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 relies not only on the WordNet database for semantic relationships but also on Magnini's semantic domain database, which is an extension of WordNet. The domain-chaining algorithm is a linear algorithm. Second, to handle proper nouns, we gather all of the ones that occur in a news story together in a chain reserved for proper nouns. In this thesis we also discuss the linguistic limitations of lexical chainers to represent textual meaning.

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 doctoral/research institutions in both public and private sectors separately. The results of this study found that (1) overall, it is slightly evident that there is a financial nexus between college choice and persistence among full-time, first-time, first-year freshman students; (2) the nexus between college choice and persistence may be different by the Carnegie Classification, and (3) the pattern of the direct effects of financial variables (i.e., tuition and financial aid) on persistence was different from the previous results. Unlike in the previous studies, tuition increases appeared to have a positive effect on the enrollment of full-time, first-time, first-year freshman students attending institutions of all Carnegie Classifications. The result suggests that price may reveal a "quality effect" and that higher tuition institution may signal higher quality. In both public and …
