The present study was a retrospective chart review (N=128) that investigated the efficacy of profiles derived from the three factors of the Eating Inventory® test (EI) - cognitive restraint, disinhibition, and hunger - to predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this population. Based on restraint theory, 7 profiles (high CR, super high CR, high D, super high D, high H, super high H, and null) were derived from the raw scores on the subscales of the EI and tested for weight loss predictive ability using direct logistic regression. Results were mixed with high CR, super high CR, and null profiles accurately predicting successful weight loss. Raw scores on the three factors (cognitive restraint, disinhibition, and hunger) were tested individually for predictive ability using direct logistic regression. Overall results indicated that the profile model accurately predicted more cases than the general factor model. This study significantly contributes to both the bariatric presurgical assessment literature and the restraint theory literature. Suggestions for future research are offered.

This thesis examines southern reactions to events that occurred in May 1856: the outbreak of civil war in Kansas and the caning of Senator Charles Sumner of Massachusetts. I researched two newspapers from the upper South state of Virginia, the Richmond Enquirer and the Richmond Daily Whig, and two newspapers from the lower South state of Louisiana, the New Orleans Times-Picayune and the New Orleans Bee to determine the extent to which political party sentiment and/or geographic location affected southern opinion towards the two events. Political party ties influenced the material each newspaper printed. Each newspaper worried that these events endangered the Union. Some, however, believed the Union could be saved while others argued that it was only a matter of time before the South seceded.

The purpose of this thesis is to explore the importance of the orphan hero in film and his resonance with the American people. It explores the orphan and the American identities, the archetypes found in myths, and the hero in American culture. The three heroes (Batman, Anakin Skywalker, and Harry Potter) represent certain aspects of orphan heroes: the capacity for sacrifice and the need to resist focusing on oneself. The type of hero each becomes has its source in the response he takes to his orphanhood. These young men suffered great loss early in their lives, but found the strength to sacrifice themselves for others, the ultimate sign of a hero.

In the immediate future, multimedia product distribution through the Internet will become main stream. However, it can also have the side effect of unauthorized duplication and distribution of multimedia products. That effect could be a critical challenge to the legal ownership of copyright and intellectual property. Many schemes have been proposed to address these issues; one is digital watermarking which is appropriate for image and video copyright protection. Videos distributed via the Internet must be processed by compression for low bit rate, due to bandwidth limitations. The most widely adapted video compression standard is MPEG-4. Discrete cosine transform (DCT) domain watermarking is a secure algorithm which could survive video compression procedures and, most importantly, attacks attempting to remove the watermark, with a visibly degraded video quality result after the watermark attacks. For a commercial broadcasting video system, real-time response is always required. For this reason, an FPGA hardware implementation is studied in this work. This thesis deals with video compression, watermarking algorithms and their hardware implementation with FPGAs. A prototyping VLSI architecture will implement video compression and watermarking algorithms with the FPGA. The prototype is evaluated with video and watermarking quality metrics. Finally, it is seen that the video qualities …

The topic of this thesis is the confrontations between William Gladstone and the Bank of England. These confrontations have remained a mystery to authors who noted them, but have generally been ignored by others. This thesis demonstrates that Gladstone's measures taken against the Bank were reasonable, intelligent, and important for the development of nineteenth-century British government finance. To accomplish this task, this thesis refutes the opinions of three twentieth-century authors who have claimed that many of Gladstone's measures, as well as his reading, were irrational, ridiculous, and impolitic. My primary sources include the Gladstone Diaries, with special attention to a little-used source, Volume 14, the indexes to the Diaries. The day-to-day Diaries and the indexes show how much Gladstone read about financial matters, and suggest that his actions were based to a large extent upon his reading. In addition, I have used Hansard's Parliamentary Debates and nineteenth-century periodicals and books on banking and finance to understand the political and economic debates of the time.

Storm water sediment runoff from disturbed landscapes has the potential to impair aquatic environments. Small construction sites of 1-5 acres in the United States are currently regulated by the United States Environmental Protection Agency to minimize storm water runoff damages to the environment. Gas well construction sites are similar to other construction sites in how the landscape is altered, but are not similarly regulated. This study identified sediment runoff from gas well development sites by collecting it in traps and weirs, and by measuring sediment debris lobes. Sediment primarily consisted of silt and clay sized particles. Sediments from two gas well sites formed five debris lobes that ranged in size from 325 to 3,290 square feet. Sediment loadings estimated from the debris lobes averaged 57.1 tons per year/acre. Future studies should focus on further quantification of sediment movement off of gas well sites and identify effective erosion control methods.

Fear is one of the oldest and most basic of human emotions. In this thesis, I will explore the topic of fear in relation to literature, both a staple of the horror genre as well as a device in literary works, as well as in my own writings. In addition, I will use Sigmund Freud's theory of the “uncanny” as a possible device to examine the complexities of fear and its effects both on the mind and body through the medium of literature, and, more specifically, where and how these notions are used within my own short stories. By exploring how and why certain fears are generated, we may be able to better examine our own reactions in this regard.

Balakirev's two early piano and orchestra works, Grande Fantaisie on Russian Folk Songs and Concerto Op. 1 in F# Minor, were composed in the middle of the nineteenth century when in Russia there were no particularly important works for piano and orchestra. Balakirev was still a teenager when he wrote these two pieces and unfortunately both remained unfinished. However the beauty and remarkable compositional achievement of these works should be highly recognized. There are six chapters in this essay. The general background, purpose and the state of research are discussed in the first chapter. The second chapter presents Balakirev's biographical information and the overview of his works for piano and orchestra is stated in Chapter III. Individual works, Grande Fantaisie and Concerto in F# Minor are discussed in the chapters IV and V, which including discussing compositional background, analysis and diagram of structural schemes. The last chapter concludes with Balakirev's contribution to Russian music and the development of the Russian concerto coming into its own. It deals particularly with Balakirev's approach to folk songs, which gives the concerto a unique Russian aesthetic, in addition to his ability to write in the European tradition.

The aspiration of this dissertation is to bring forth the significance of Shostakovich's Piano Sonata Op.12. This sonata is a hybrid of the German musical tradition, Russian Modernism, and Liszt's thematic transformation technique. It demonstrates Shostakovich's highly intellectual compositional skills influenced by the education that he received at St. Petersburg Conservatory as well as the exposure to modern music in the 1920s. This dissertation discusses composition techniques, such as the harmonic piers adapted from Alexander Scriabin, neighboring-tone technique, which involves the application of semitone cell throughout the piece, as well as the technique of thematic transformation borrowed from Liszt. These all come together by Shostakovich's design in the most controversial sonata form. The Piano Sonata Op.12 also sheds light on Shostakovich's early compositional style and proves its contribution to the evolution of sonata genre in the twentieth-century.

The global emphasis on human rights has generated a surge of studies into what causes regimes to abuse the basic rights of their citizens. Causes of abuse can be internal or external in nature, based on economics, politics or cultures. This study examines the effects of foreign aid and foreign direct investment on three types of human rights: personal integrity, civil and political, and subsistence. I perform ordinary least squares regression analyses with panel-corrected standard errors on a pooled cross-sectional time series design incorporating 127 countries from 1976 to 1996. While my results are not significant, it is important to observe that there is a tendency toward negative relationships for the majority of the analyses.

The purpose of this experiment was to compare the effects of combining negative reinforcement and positive reinforcement during teaching with the effects of using positive reinforcement alone. A behavior was trained under two stimulus conditions and procedures. One method involved presenting the cue ven and reinforcing successive approximations to the target behavior. The other method involved presenting the cue punir, physically prompting the target behavior by pulling the leash, and delivering a reinforcer. Three other behaviors were trained using the two cues contingent on their occurrence. The results suggest that stimuli associated with both a positive reinforcer and an aversive stimulus produce a different dynamic than a situation that uses positive reinforcement or punishment alone.

Large amounts of industrial fertilizers are used to maximize crop yields. Unfortunately, they are not completely consumed by plants; consequently, this leads to soil pollution and negative effects on aquatic systems. An alternative to industrial fertilizers can be found in legume plants that provide a nitrogen source that is not harmful for the environment. Legume plants, through their symbiosis with soil bacteria called rhizobia, are able to reduce atmospheric nitrogen into ammonia, a biological nitrogen source. Establishment of the symbiosis requires communication on the molecular level between the two symbionts, which leads to changes on the cellular level and ultimately results in nitrogen-fixing nodule development. Inside the nodules hypoxic environment, the bacterial enzyme nitrogenase reduces atmospheric nitrogen to ammonia. Medicago truncatula is the model legume plant that is used to study symbiosis with mycorrhiza and with the bacteria Sinorhizobium meliloti. The focus of this work is the M. truncatula nodulation mutant nip (numerous infections and polyphenolics). The NIP gene plays a role in the formation and differentiation of nodules, and development of lateral roots. Studying this mutant will contribute knowledge to understanding the plant response to infection and how the invasion by rhizobia is regulated. Previous genetic mapping placed NIP …

Numerous authoritarian states use institutions usually associated with democratic regimes like a constitution, elections, and a legislature. This seems to be counterintuitive. Authoritarian regimes should rather shrink away from democratic institutions. Elections can be won by the opposition and legislatures can make decisions against the interests of the ruler. So, why do autocratic regimes install institutions which limit their power and threaten their survival in office? Assuming actors behave rationally, one should expect authoritarian rulers only to introduce procedures working in their favor. This study looks at the effect of institutions in authoritarian regimes. The findings suggest that legislatures significantly lower the chances of regime breakdown in the long run. However, particularly in election years, authoritarian regimes are facing a higher likelihood of failure.

The Octuor pour instruments a vents (or Octet), written in 1922-1923 by Igor Stravinsky, is a piece in three movements for a curious assortment of instruments: two trumpets, two trombones, flute, clarinet and two bassoons. It is one of four influential chamber works for winds by Stravinsky to include trumpet. Of these pieces, the Octet contains the fewest number of players but is no less complex and important in Stravinsky's oeuvre. The Octet helped mark the beginning of the neoclassical period in twentieth-century music. Chapter 2 examines the life and musical background of the composer. It also reveals the history surrounding the origin of the Octet and its role in neoclassicism. Chapter 3 discusses the role of the Octet in the wind ensemble and orchestral repertoire, and includes a representative performance history, including the premiere. Chapter 4 provides analytical insights into the construction and format of the piece. Chapter 5 provides suggestions regarding style in Stravinsky's music, including interviews with important figures in the trumpet world. Chapter 6 concludes the guide with specific suggestions regarding preparation and performance of the Octet.

This two-part study of the criminal investigation process first evaluated the frequency with which patrol officers solve cases assigned to the investigations division and then examined how detectives spent their time, both on case assignments and on other activity not related to current case assignment. Cases assigned to the investigations division for follow up were examined to determine how often a case was cleared by the patrol officer. The detective's time was then evaluated in order to determine how much time detectives spent on investigative tasks and other activities. This study confirms that the patrol officer should be given more time to conduct preliminary investigations for specific cases, and that tasks performed by detectives could be shifted to other personnel in the department. Both actions should serve to positively impact case clearance rates.

The purpose of this study was to conduct a survey to identify the beliefs and practices of conservative Protestant parents, which assisted in clarifying the assertions in the current literature regarding conservative Protestant parenting. Additionally, this researcher sought to determine the applicability of child parent relationship therapy (CPRT), a filial therapy model based upon the principles of child centered play therapy, for conservative Protestant parents by ascertaining the need for cultural modifications. Beliefs and practices of conservative Protestants were measured using the Protestant Parenting Inventory (PPI), an original instrument developed through a series of focus groups and pilot testings. The population comprised 148 mothers and fathers from 4 Southern Baptist churches in and around the Dallas/Fort Worth metroplex. Exploratory factor analysis was applied to the data in order to increase internal consistency estimates and percent of explained variance. Criterion coding of demographic data allowed a multiple regression analysis to determine which demographic variables were significant predictors of participant responses on the PPI. Descriptive statistics allowed the researcher to investigate the compatibility of conservative Protestants and CPRT. Results of this study both confirm and refute past findings regarding conservative Protestants. Results also revealed the need for some cultural modifications to CPRT …

This study examined the effect of a score card¬-based performance pay plan in a professional services firm. The plan was implemented in response to a decreasing trend in productivity and a desire for a formal incentive compensation plan. Performance of manager and senior manager accountants were analyzed across two departments over a five year period. A definitive account of the effects of the intervention is limited by the case-¬study design, but the data does suggest that the performance pay plans used did not adversely affect performances. Design limitations of the plan and future research are also discussed.

This thesis sets out to develop a beginning of a philosophy of water by considering philosophical implications of ecological crises currently happening along the waters of the Ganges River. In my first chapter, I give a historical account of a philosophy of water. In my second chapter, I describe various natural and cultural representations of the Ganges, accounting for physical features of the river, Hindu myths and rituals involving the river, and ecological crises characterized by the pollution and damming of the river. In my third and final chapter, I look into the philosophical implications of these crises in terms of the works of the contemporary philosopher Bruno Latour.

This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I end-of-course examination, given as a district option to Algebra I students, and student final course grades as determined by classroom teachers. The study compared students' performance in these three areas during the 2004-2005 academic year in one suburban school district in North Texas. The study considers the type of schedule, either traditional or 8-block, between students in teachers' classes who teach the same course on both schedules concurrently. This study also investigates a qualitative aspect by including a short opinion survey of teachers' perceptions regarding student academic performance, teacher satisfaction and retention, and the ability to accomplish curricular goals. Findings from this research suggest course schedule does not have significant effects on student academic performance as measured using analyses of covariance comparisons with a 0.05 alpha-level, leading to the conclusion that a particular course schedule does not adversely impact student performance on academic measures. However, in some comparisons conducted within the course of the …

The purpose of this study is to explore the differences and characteristics between first time felony probationer and recidivist felony probation offender. The importance of said studies grows significantly, given current trends of sentencing offenders to probation. Using archived data on random sample of felony offenders in 2000 and based on information acquired and maintained by the Denton County Community Supervision and Corrections Department (CSCD), the study consists of 40 first time felony offenders and 40 recidivist felony offender placed on probation during the year 2000. The method consists of a longitudinal comparison model. To examine the research question, descriptive statistics are used to compare basic demographics. Then, in order to answer the research question bi-variate significant tests, Chi-square and Independent Sample T-tests were employed when appropriate. Results indicate differences between first time felony probation offenders and recidivist felony probationers.

A bacterial challenge assay was developed utilizing the earthworm, Lumbricus terrestris, in order to assess potential immunotoxic effects from exposure to specific polychlorinated biphenyl congeners. Earthworms were inoculated with Aeromonous hydrophila, establishing a 10-day LD50. In vitro assays for effects of PCBs on phagocytosis agreed with mammalian studies, demonstrating potent suppression of phagocytosis by the non-coplanar PCB congener 138 and no suppression by the coplanar congener 126. However, when the effects of the two PCB congeners were evaluated for suppression of resistance to a whole animal infection challenge assay, coplanar PCB 126 decreased the ability of L. terrestris to withstand infection while non-coplanar PCB 138 did not.

The presence of deposits on the secondary side of pressurized water reactor (PWR) steam generator systems is one of the main contributors to the high maintenance costs of these generators. Formation and transport of corrosion products formed due to the presence of impurities, metals and metallic oxides in the secondary side of the steam generator units result in formation of deposits. This research deals with understanding the deposit formation and characterization of deposits by studying the samples collected from different units in secondary side system at Comanche Peak Steam Electric Station (CPSES). Fourier transform infrared spectrophotometry (FTIR), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) have been used for studying the phases, morphologies and compositions of the iron oxides formed at Unit 1 and Unit 2 of secondary side of steamgenerator systems. Hematite and magnetite were found to be the dominant phases of iron oxides present in the units. Fe, Cr, O, Ni, Si, Cl and Cu were found in samples collected from both the units. A qualitative method was developed to differentiate iron oxides using laser induced breakdown spectroscopy (LIBS) based on temporal response of iron oxides to a high power laser beam. A quantitative FTIR technique was …

The state of Texas passed the Student Success Initiative (SSI) in 1999 which requires all 3rd graders to pass the reading portion of the Texas Assessment of Knowledge and Skills (TAKS) test to be promoted to the 4th grade, and for 5th graders to pass the reading and math portions of the TAKS test to be promoted to the 6th grade. Beginning in spring 2008, 8th graders will also need to pass the reading and math portions of the TAKS test to be promoted to the 9th grade. The purpose of this study was to examine the academic performance of 3rd and 5th grade students who did not meet the passing standard on the TAKS test and were retained during the 2005-2006 school year. The population of this study included 33 3rd graders and 49 5th graders who were retained during the 2005-2006 school year due to not meeting the promotion requirements of the SSI. There was also a second population of 49 5th graders who were retained in 3rd grade during the 2003-2004 school year due to not meeting the promotion requirements of the SSI. These students were enrolled in the 5th grade for the first time during the …

In recent years scholars have begun to re-evaluate the works, writings, and life of Robert Schumann (1810-1856). One of the primary issues in this ongoing re-evaluation is a reassessment of the composer's late works (roughly defined as those written after 1845). Until recently, the last eight years of Schumann's creative life and the works he composed at that time either have been ignored or critiqued under an image of an illness that had caused periodic breakdowns. Schumann's late works show how his culture and the artists communicating within that culture were transformed from the beginning to the middle of the nineteenth century. These late works, therefore, should be viewed in the context of Schumann's output as a whole and in regard to their contributions to nineteenth-century society. Schumann's contributions, specifically to the genre of the song cycle from 1849 to 1852, are among his late compositional works that still await full reconsideration. A topical study, focusing on three themes of selections from his twenty-three late cycles, will provide a critical evaluation of Schumann's compositional output in the genre of the song cycle. First, Schumann's political voice will be examined. The political events that led to the mid-nineteenth-century revolutions inspired crucial …
