Pulse oximeters are used in operating rooms and recovery rooms as a monitoring device for oxygen in the respiratory system of the patient. The advantage of pulse oximeters over other methods of oxygen monitoring is that they are easy to use and they are non-invasive, which means it is not necessary break the skin to extract blood for information to be obtained. The standard for the measurement of partial pressure of CO2 and O2 is an arterial blood gas analysis (ABG). However routine monitoring using this method on a continuous basis is impractical since it is slow, painful and invasive. Measuring carbon dioxide is critical to preventing ailments such as carbon dioxide poisoning or hypoxia. The problem is, currently there is no known effective non-invasive method for accurately measuring carbon dioxide in the body to properly assess the adequacy of ventilation. The objective of this study was to experimentally use spectroscopy in the visible spectrum and the principles of operation of a pulse oximeter to incorporate a method of non-invasive real-time carbon dioxide monitoring that is as quick and easy to use.

This case study is a performance improvement project focusing on the organizational system and management practices in a center for children with autism. Staff interviews and a process improvement map were used to assess the organization and assist in identifying potential solutions. The analysis led to treatment integrity as the key outcome measure. The center's administrative team decided to implement treatment delivery process changes to impact treatment integrity measures. This study measured data sheet changes and treatment implementation to determine the impact of process changes on treatment integrity. High levels of variability in treatment integrity across all teams were observed, and results suggest that a process change was not enough to increase treatment integrity. Further study is necessary to investigate measurement and impact of treatment integrity on desired outcomes for children with autism.

This collection of seven representative original short stories will include four short stories relating to a fictional location in Dallas, the Starry Skies gay country-and-western dance hall. Three short stories set in fabulous, sometimes absurd settings, will follow. A preface dealing with the nature of fictional place and non-fictional place in fiction will precede the collection of short stories.

This thesis discusses the rise of the Republican party in Texas and specifically Harris County. The time period is the decade between the Presidential election of Dwight D. Eisenhower and the campaign of Jack Cox for Governor. Changes in the structure and leadership of the Republican party at the state level and specific precincts are examined in detail in chapter one. Leaders in Houston during this time period, such as Jesse Jones, Roy Cullen, and Oveta Culp Hobby are discussed in chapter two. The elections of Eisenhower, Cox, and Republican John Tower are analyzed in chapter three. The conclusion finds six major factors for the political changes occurring in Harris County, including economic and demographic changes. Main sources for this work included the Harris County Democratic party records and the Jack Cox Papers at the Center for American History, the Eisenhower Library, and the John Tower Papers.

This study examined the relationship between reports of controlling behaviors and education/income in a sample of 297 abused women and 2951 non-abused women in married or cohabitating relationships. This study confirmed that women who reported abuse were more likely to report all five of the controlling behaviors than women who did not report abuse. However, the abuse and non-abuse samples did show similar relationships between the controlling/isolating behaviors and the SES variables. This study found that the higher the respondent's or their partner's education and income, the less likely they were to report controlling/isolating behaviors. Also, the respondent's education and income had the same number of statistically significant relationships with the controlling behaviors as the partner's education and income.

The expressive marking "schattenhaft" appears twice in Gustav Mahler's symphonies: at the beginning of the scherzo in the Seventh and within the first movement of the Ninth. Theodor Adorno's observations regarding Mahler's use of this marking, which connect it to Schopenhauer and Romantic aesthetics, provide the framework for an examination of possible meanings of these two passages in Mahler. Drawing also on references elsewhere in Adorno's book to stylistic and formal features peculiar to Mahler's music, and especially on the comparison he makes between the experiences of reading novels and listening to Mahler's symphonies, this thesis demonstrates that close analysis of the "schattenhaft" passages offers a valuable point of entry into the thinking of both Adorno and Mahler.

Raptor rehabilitation has become commonplace globally, yet studies on the survival and adaptation of great horned owls (Bubo virginianus) after release has been neglected to an appreciable extent. The primary objective of this study is to provide quantitative data on the success of rehabilitated and released great horned owls in the North Texas region. Owls (N=12) were rehabilitated and released onto the Ray Roberts Greenbelt Corridor in Denton County, Texas, and monitored using radio telemetry to evaluate home range (November 2002 - February 2005). With approximately 75% of the birds released for this study surviving until transmitter battery failure, it is believed that the rehabilitation process was successful for these birds.

This study used data from the homicides in Chicago 1965-1995 dataset (N=9,340) to examine the relationship between the use of certain types of weapons in criminal homicides by gender, race, age, victim-offender relationship, motive, location, and changes over time. Differential association and sex-role theory were utilized to argue why gender differences would occur in type of weapon used in a homicide. Subculture of violence theory was used to emphasize that the place where the homicide occurs, the relationship between the victim and offender, motive of the offender, and the remaining variables affects the type of weapon used to kill. Significant relationships were found for all bivariate analyses performed. The type of weapon used to kill differs most by sex of offender, resulting in a moderately strong association. The type of weapon used to kill differs least by age of offender and although statistically significant, the association between the two is very weak.

A variable that may be associated with performance improvements is goal setting (within and across days). Easy-to-achieve goals will likely produce gradual trends in improvement and difficult-to-achieve goals steeper trends. The purpose of the current experiments was to study the effects of setting easy-to-achieve and difficult-to-achieve goals on the level, trend, and variability of correct, incorrect, and skip responses for math tasks when reinforcement contingencies and numbers of practices were held constant. Five undergraduate students answered math problems on flash cards in 30s timings. Single case design elements were used to evaluate the effects of different types of goals on the speed and accuracy of performance. The results revealed that goal setting primarily increased the frequency of incorrect responses and both the level and trend of skip responses. The implications of these findings and other important variables that influence the effectiveness of goal setting are discussed. In addition, the authors suggest guidelines to follow when implementing goals to improve performance.

The research investigated the impact of sexual harassment on withdrawal behaviors and attitudes toward harassment by examining the gender composition of the harassment dyad and the organizational status of the perpetrator in relation to the victim. Archival data from the Inter-University Consortium for Political and Social Research at the University of Michigan was used to obtain surveys in which participants rated their attitudes and experiences related to sexual harassment. Only individuals who reported experiencing sexual harassment within the 24 months prior to data collection are included in the current research. A MANOVA was conducted to determine if withdrawal behaviors and attitudes of victims varied by the gender dyad and/or the organizational status of the perpetrator. Results indicated that individuals harassed by people with higher organizational status displayed more withdrawal behaviors in the form of decreased productivity and increased use of sick, annual, and unpaid leave. Individuals harassed by a member of the same gender also used more unpaid leave. Interestingly, individuals harassed by members of the opposite gender, tended to disagree more strongly with the attitude index measuring cautious awareness of sexual harassment.

A synthetic approach to macromolecules of acetylenic arrays and luminescent properties is proposed and the execution of initial steps is described. Palladium-catalyzed coupling of 1,3,5-triiodobenzene with trimethylsilylbuta-1,3-diyne, trimethylsilylocta-1,3,5,7-tetrayne, and trimethylsilylhexadeca-1,3,5,7,9,11,13,15-octayne to yield the new 1,3,5-tris(trimethylsilylbuta-1,3-diynyl)benzene and the proposed 1,3,5-tris(8-(trimethylsilyl)octa-1,3,5,7-tetraynyl)benzene and 1,3,5-tris(trimethylsilyl)hexadeca-1,3,5,7,9,11,13,15-octaynyl)benzene respectively. The proposed three-coordinate Au (I) complexed macromolecules will be derived from the metallation of the aforementioned alkynylated arenes.

Motor vehicle theft is the costliest property crime in the United States equaling billions of dollars in losses each year. Despite law enforcement success in decreasing the rate of motor vehicle theft in recent years, the actual number of thefts has increased. It is vital for law enforcement agencies to know who is committing motor vehicle theft and where vehicles are being stolen. This study answers these questions by examining offender demographic characteristics and the location types most targeted for motor vehicle theft in Texas from 2001 to 2005. The state of Texas was chosen because Texas has continually been ranked second in the Federal Bureau of Investigation's Uniform Crime Report for the number of reported incidents of motor vehicle theft in the United States.

Music that is categorized as part of the Indianist movement in American music (ca. 1890-1925) typically evokes Native American culture, ritual, story, or song through compositional gestures. It may also incorporate Native American tunes. Amy Beach (1867-1944) is considered to have composed five Indianist works, but her Theme and Variations for Flute and String Quartet, op. 80 has not been included as one of them. This thesis rethinks categorization of the piece, seeking the "Indian" in it through examination of its gestures, instrumentation, and relationship to contemporary Indianist compositions.

In 1939, composer Julia Smith's first opera Cynthia Parker dramatized the story of a Texas legend. Smith manipulated music, text, and visual images to make the opera accessible for the audience in accordance with compositional and institutional practices in American opera of the 1930s. Transparent musical themes and common Native Americans stereotypes are used to define characters. Folk music is presented as diegetic, creating a sense of authenticity that places the audience into the opera's Western setting. The opera is codified for the audience using popular idioms, resulting in initial but not lasting success.

The results of the Advanced Placement exams given to students in 2006 were disaggregated according to gender. The level of performance was compared between males and females using Cohen's d. The standardized differences between male and female performance group levels were compared to previous results for the 1992 Advanced Placement (AP) exams. One purpose of this study was to determine whether or not the male-favored results that existed in 1992 still existed in the 2006. This study found that differences still exist in results based on gender and no real progress has been made in reducing the gap in achievement between males and females. A second purpose of this study was to compare and contrast the local data to the national data set to see if scores in Brazosport were similar to scores collected at the national level. To determine if similar results would be obtained at the local level the results of 267 Advanced Placement exams taken by 190 students from Brazsosport Independent School District in 2006 were disaggregated according to gender. The level of performance was compared between males and females using Hedge's g. Because of limited sample size, only 9 Advanced Placement exams were reviewed at the …

How does respect for human rights affect the disbursement of food aid by US foreign policymakers? Scholars analyzing foreign aid generally look at only total economic aid, military aid or a combination of both. However, for a more nuanced understanding of human rights as a determinant of foreign aid, the discrete foreign aid programs must be examined. By disentangling component-programs from total aid, this analysis demonstrates how human rights influence policymakers by allowing them to distribute food aid to human rights abusing countries. Consequently, policymakers can promote strategic objectives with food aid, while legally restricted from distributing other aid. The primary theoretical argument, which links increasing human rights abuse with increasing food aid, is supported by results from a Heckman model. This procedure models the two-stage decision-making process where foreign policymakers first, select countries for aid and then, distribute aid to those selected.

Biracial individuals undergo a developmental process that is different than monoracial individuals. Not only do they have to develop a strong and cohesive self-esteem, but also develop a strong and cohesive racial identity to have a healthy self-concept. The media is a social structure that has infiltrated into many aspects of American lives, including their racial identity. The media perpetuates current beliefs concerning race and racial identity. This research investigates how biracial identity has been portrayed in the media. Historically, biracial individuals have been portrayed as the tragic "mulatto" because of their confused racial background. In addition, mulatto women have been stereotyped as exotic and sexual objects. A content analysis was used to investigate how the media presents biracial identity. Only movies with black/white biracial individuals were watched. The categories under study included perceived race, character's race, skin color, likeability, sex appeal, ability to contribute, ability to be violent, mental health, overall positive portrayal social, and negative portrayal score. This study may suggest that the media is making attempts to rectify old stereotypes. Overall, this study does demonstrate that the media portrays biracial and black characters differently in film. One overarching theme from these results implies that the perception of …

Many of Toni Morrison's African-American characters attempt to change their circumstances either by embracing the white dominant culture that surrounds them or by denying it. In this thesis I explore several ways in which the characters do just that-either embrace or deny the white culture's right to dominion over them. This thesis deals primarily with five of Toni Morrison's novels: The Bluest Eye, Beloved, Paradise, Sula, and Tar Baby.

Retail geography is a field of study that is growing in significance and importance within the academic, business, economic, and governmental realms. This study's main focus is on the changing retail environment with regards to business location and function within a small Midwestern city. The research focuses on Port Huron, Michigan because of the growth and shift of the retail community within the city over the past twenty years. The study specifically examines the changing influence and roles of Port Huron's central business district and of Birchwood Mall a retail development opened on the urban area's north end in 1990. The study uses the chi-squared, ANOVA, and cross tabulation statistical tests to analyze the changing geography of retail functions in the city. These statistics are used along with relative entropy equations to distinguish areas of high diversification, changing area functions, and common locations for multiple retail types.

An alternating treatment design was used to systematically evaluate the communication response forms, picture exchange communication system (PECS) or sign language, selection for a child with pervasive developmental disorder-not otherwise specified, profound hearing loss, and cochlear implants. The child had a limited pool of high preference items and very few functional skills. Key factors for this child included a structured environment that created a verbal community and contingent access to high preference items. No preference in communication response form was observed. The child successfully used four response forms to communicate: gestures, PECS, sign language, and vocalization. The results are discussed in terms of decision making factors in the selection of response forms.

Secondary analysis of data from the National Longitudinal Study of Adolescent Health is used to examine possible explanatory variables for sexual health outcomes. Linear and logistic regression analyses were conducted to examine the relationship between sexual health outcomes and topical content in sexuality education, controlling for race, biological sex, low socioeconomic status, and religiosity. Results indicated increasing topical content in sexuality education had a positive effect on knowledge acquisition and confidence, but no statistically significant effect on engagement in sexual risk behavior or likelihood of reporting sexual coercion. Control variables were significant predictors and overall model fit was low, indicating topical content in sexuality education is minimally important in creating adolescent sexual behavior. Further exploration of differing aspects of sexuality education is suggested.

Using African American newspapers, this study examines the consensual opinion of articles and editorials regarding two events associated with the space race. One event is the Soviet launch of Sputnik on October 4, 1957. The second is the Apollo 11 moon landing on July 20, 1969. Space Race investigates how two scientific accomplishments achieved during the Cold War and the civil rights movement stimulated debate within the newspapers, and that ultimately centered around two questions: why the Soviets were successful in launching a satellite before the US, and what benefits could come from landing on the moon. Anti-intellectualism, inferior public schools, and a lack of commitment on the part of the US government are arguments offered for analysis by black writers in the two years studied. This topic involves the social conditions of African Americans living within the United States during an era when major civil rights objectives were achieved. Also included are considerations of how living in a "space age" contributed to thoughts about civil rights, as African Americans were now living during a period in which science fiction was becoming reality. In addition, this thesis examines how two scientific accomplishments achieved during this time affected ideas about education, …

Aggression in dogs is a significant public health concern with 7.2 mortality cases per 100 million inhabitants and approximately 4.7 million dog bites annually. Canine aggression is typically viewed as a genetic trait and treated as pathology through the use of medical or respondent behavioral procedures. In this study the effects of the differential negative reinforcement of safe, alternative behaviors to aggression using distancing as the reinforcer were evaluated. The results demonstrated that even when the aggression was in evidence throughout most of the dog's lifetime, it responded quickly to changes in reinforcement contingencies.

Calculations were performed on transition-metal complexes to (1) extrapolate the structure and bonding of the ground and phosphorescent states (2) determine the luminescence energies and (3) assist in difficult assignment of luminescent transitions. In the [Pt(SCN)4]2- complex, calculations determined that the major excited-state distortion is derived from a b2g bending mode rather than from the a1g symmetric stretching mode previously reported in the literature. Tuning of excimer formation was explained in the [Au(SCN)2]22- by interactions with the counterion. Weak bonding interactions and luminescent transitions were explained by calculation of Hg dimers, excimers and exciplexes formed with noble gases.
