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.

Personality measures are often used by organizations to select and develop employees in a way that maximizes their performance. Studies examining the relationship between personality and job performance have found some evidence for their utility in a variety of situations. Data was collected from a large restaurant company (N=9,800) in which hourly employees took a personality test for selection. Supervisory performance ratings and turnover data were also included for some employees. A three factor model of contextual performance consisting of personal support, organizational support, and conscientiousness initiative was tested and supported. The personality scales with the strongest relationship to performance, included drive and energy, friendliness, and emotional consistency. Effect sizes were relatively similar to previous meta-analytic studies, with the exception of a facet of conscientiousness which revealed a lower correlation with performance than expected. A differential pattern of correlations between the personality scales and performance dimensions was observed that supported some of the theoretically aligned constructs. The correlations between the personality variables and performance were unexpectedly higher among customer facing employees than team-based employees. No hypothesized interaction effects were supported, but some nonlinear relationships were found among some of the personality scales and performance. Drive and energy was a statistically …

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.

This dissertation deals with two major topics that involve spectroscopic studies of (a) divalent group 10 metals and (b) silver(I)-phosphine complexes. The scope of the work involved the delineation of the electronic structure of these complexes in different environments and their use in electronic devices. The first topic is a look at the luminescence of tetrahedral silver(I)-phosphine complexes. Broad unstructured emissions with large Stokes shifts were found for these complexes. Computational analysis of the singlet and triplet state geometries suggests that this emission is due to a Jahn-Teller type distortion. The second topic represents the major thrust of this research, which is an investigation into the electronic structure of M(diimine)X2 (M= Pt(II), Pd(II), or Ni(II); X = dichloro, or dithiolate ligands) complexes and their interactions with an electron acceptor or Lewis acid. Chapter 3 assesses the use of some of these complexes in dye sensitized solar cells (DSSCs); it is shown that these complexes may lead to a viable alternative to the more expensive ruthenium-based dyes that are being implemented now. Chapter 4 is an investigation into donor/acceptor pairs involving this class of complexes, which serves as a feasibility test for the use of these complexes in organic photo-voltaics (OPVs) …

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.

A unique process of fabricating a strained layer GexSi1-x on insulator is demonstrated. Such strained heterostructures are useful in the fabrication of high-mobility transistors. This technique incorporates well-established silicon processing technology e.g., ion implantation and thermal oxidation. A dilute GeSi layer is initially formed by implanting Ge+ into a silicon-on-insulator (SOI) substrate. Thermal oxidation segregates the Ge at the growing oxide interface to form a distinct GexSi1-x thin-film with a composition that can be tailored by controlling the oxidation parameters (e.g. temperature and oxidation ambient). In addition, the film thickness can be controlled by implantation fluence, which is important since the film forms pseudomorphically below 2×1016 Ge/cm2. Continued oxidation consumes the underlying Si leaving the strained GeSi film encapsulated by the two oxide layers, i.e. the top thermal oxide and the buried oxide. Removal of the thermal oxide by a dilute HF etch completes the process. Strain relaxation can be achieved by either of two methods. One involves vacancy injection by ion implantation to introduce sufficient open-volume within the film to compensate for the compressive strain. The other depends upon the formation of GeO2. If Ge is oxidized in the absence of Si, it evaporates as GeO(g) resulting in spontaneous …

Succession planning is the creation of a pool of high potential employees that receive specific training and developmental opportunities with the intention of promotion. There is a definite need to deepen our understanding of what implications there are from a psychological point of view for employees when a major process like succession planning is implemented. Employee engagement is the experienced commitment, which leads to discretionary effort. The purpose of this research is to explore an underlying factor structure for engagement drivers and understand how a major organizational initiative, succession planning, impacts employee engagement. This research was conducted at a petroleum organization in the Southwest United States (N = 2023) and compares engagement based on group membership in a succession planning process (Informed-High Status, Uninformed-High Status, and Uninformed-Low Status). The underlying factor structure of drivers was found to have one factor of engagement. There was a significant difference in the engagement levels based on membership within the succession plan (high status versus low status). However, communicating to an employee their involvement in the succession plan did not differentiate between engagement levels.

Grandparent-headed families are diverse in nature and represent a rapidly growing family type. While challenges facing grandparent caregivers are well documented, less is known about the well-being of their grandchildren, with many early studies relying on small samples of convenience. This study used an existing large national database, the National Survey of America's Families (NSAF), to compare differences in well-being of both children and grandparent caregivers across the independent variables of family type, ethnicity, gender, and age. Findings suggested better mental health and less parental aggravation for caregivers in traditional two parent intact families as compared to grandparents co-parenting in a multi-generation home, skipped generation grandparents (raising their grandchild with no parent present) or single parents. Skipped generation grandparents in particular reported most caregiver aggravation. Child physical health was reported to be worse by skipped generation grandparent caregivers. Behavior problems were reported to be worse for children in grandparent headed households than those in traditional families, particularly for teenagers raised in skipped generation households by their grandmothers. Specific results, limitations and future directions for research on grandparent-headed households were discussed.

Project SCORE: Life Skills for Future Success, is a structured, 20-lesson curriculum, designed to help students develop academic and life skills, as well as self-responsibility, commitment, optimism, respect, and excellence. The curriculum was presented during 36, 90-minute class periods over the fall semester of the students' freshmen year. The purpose of this study was to determine the effectiveness of Project SCORE at improving grades, learning strategies, self esteem and coping skills with freshmen students at an inner-city high school. In order to evaluate the program, students completed paper-pencil surveys at the beginning and end of the semester in which they were enrolled in the Project SCORE class. In addition, teachers completed evaluations on their perceptions of each student's peer relationships, classroom behavior, mood, and activity level. All teachers and students involved in the course were asked to complete an evaluation to determine their level of satisfaction with the course and areas in need of improvement. Lastly, information pertaining to grades, discipline and standardized test scores were used to determine the impact of SCORE. Participants were 333 9th grade students at a large 4A high school in Texas. Findings suggest that SCORE had a positive effect on coping resources, study skills …

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.

The purposes of the present study are to: (a) describe the beliefs and practices of the US and Taiwan (TW) public and private kindergarten teachers regarding developmentally appropriate practice (DAP), (b) examine the group differences between the four groups of teachers, and (c) identify the salient factors related to the variability of developmentally appropriate beliefs and practice in these teachers. Three hundred and fifty-seven kindergarten teachers participated in the study. The group sizes were 123, 123, 57, and 54 for Taiwan private, Taiwan public, US private, and US public kindergarten teachers, respectively. A survey was used to collect data. Findings from this study showed: (a) Both the US and Taiwan kindergarten teachers highly endorsed beliefs about DAP; (b) US and Taiwan kindergarten teachers also held strong beliefs about developmentally inappropriate practices (DIP); (c) DAP activities occurred regularly in the classrooms; (d) developmentally inappropriate practice (DIP) activities also took place a lot although they were lower than the DAP activities; (e) the Taiwan teachers had higher beliefs about DAP and lower beliefs about DIP than the US teachers; (f) the US teachers reported both higher DAP and DIP activities than the Taiwan teachers; (g) there were no differences between public and …

When a stock is added into the S&P 500 Index, it is automatically "cross-listed" in the index derivative markets (i.e., S&P 500 Index futures and Index options). I examined the effects of such cross-listing on the trading volume and return volatility of the underlying component stocks. Traditional finance theory asserts that futures and "cash" markets are connected by arbitrage mechanism that brings both markets to equilibrium. When arbitrage opportunities arise, arbitrageurs buy (sell) the index portfolio and take short (long) positions in the corresponding index derivative contracts until prices return to theoretical levels. Such mechanical arbitrage trading tends to create large order flows that could be difficult for the market to absorb, resulting in price changes. Utilizing a list of S&P 500 index composition changes occurring over the period September 1976 to December 2005, I investigated the market-adjusted volume turnover ratios and return variances of the stocks being added to and deleted from the S&P 500, surrounding the effective day of index membership changes. My primary finding is that, after the introduction of the S&P 500 index futures and options contracts, stocks added to the S&P 500 experience significant increase in both trading volume and return volatility. However, deleted stocks …

With the advances in very large scale integration (VLSI) technology, hundreds of billions of transistors can be packed into a single chip. With the increased hardware budget, how to take advantage of available hardware resources becomes an important research area. Some researchers have shifted from control flow Von-Neumann architecture back to dataflow architecture again in order to explore scalable architectures leading to multi-core systems with several hundreds of processing elements. In this dissertation, I address how the performance of modern processing systems can be improved, while attempting to reduce hardware complexity and energy consumptions. My research described here tackles both central processing unit (CPU) performance and memory subsystem performance. More specifically I will describe my research related to the design of an innovative decoupled multithreaded architecture that can be used in multi-core processor implementations. I also address how memory management functions can be off-loaded from processing pipelines to further improve system performance and eliminate cache pollution caused by runtime management functions.

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.

This investigation examined the relationships between parental involvement, peer-initiated climates, and perfectionism to goal orientation as well as children's enjoyment and the intention to continue playing sport in youth sport. Participants were 188 athletes, 100 boys (M = 12.06, SD = 1.06) and 88 girls (M = 12.18, SD = .73). The athletes completed the TEOSQ, Sport MPS, PIAS, and the PeerMCYSQ. Parental support and peer task environment was related to girls' and boy's task orientation. For boys, personal standards, parental pressure, and fewer concerns over mistakes, also were related to task orientation. Ego orientation was related to peer-initiated ego and task climates, for the boys. For the girls, higher personal standard was the only variable related to ego orientation. For enjoyment, task orientation was the strongest predictor for the girls and the only predictor for the boys for enjoyment. The fewer concerns girls had over mistakes the more enjoyment they reported. For girls and boys, intention to continue playing next season was predicted only by enjoyment. However, results were varied when intention to play next year was examined. For boys, no predictors were discovered whereas for girls, higher levels of enjoyment and task orientation, and lower levels of parental …

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.

The purpose of this study was to investigate factors that compel teachers of students with emotional and behavioral disorders (E/BD) to quit or stay in their job. Invitations to participate in the study were sent to a sample of educators from each the four census regions of the United States who currently work or have worked in the past worked with students with E/BD and have participated in one or more of the Council for Children with Behavioral Disorders (CCBD) professional development events. A total of 156 educators responded to the online survey and 9 participated in the focus groups. Quantitative information generated from the survey was analyzed using frequency distributions and ANOVA, whereas, qualitative information were analyzed by summarizing and sorting information into different categories. The results were presented in narrative and tabular form and organized in response to each of the research questions. The projected high teacher turnover as depicted in the findings, were mainly attributed to workplace variables and classroom conditions. Both variables are likely to be associated with high levels of dissatisfaction and lack of commitment eventually leading to decisions by teachers of students with E/BD to leave their job. Most respondents perceived themselves as being …

The Six épigraphes antiques represent a cross-section of Debussy's creative output that traces the composer's germ-seed from his original setting of the work in 1901 as incidental music to accompany the recitation of several poems, to the four-hand piano version of 1914, and its consequent reduction for solo piano. What can be gleaned by the methods of derivation from his original sketches to the final, mature works is an understanding of Debussy's use of musical metaphor and his connection to the poetry - the Chansons de Bilitis of Pierre Louÿs. Embedded literary procedures create a new musical expression of the work whereby text and music become integrated. Rather than serving as accompaniment to the poems, the Épigraphes function as the primary vessel for the conveyance of these ancient scenes. Several of Debussy's hallmark symmetrical and structural moulds, such as the whole-tone, chromatic, octatonic, and mirroring techniques reflect the omnipresent symmetry of Classical Greece. Various other artistic creations emanated from the Épigraphes, most significantly the orchestration of Ernest Ansermet in 1939. A look at the techniques used by Ansermet for the augmentation of the piano work serves to extrapolate the multifarious layers relevant in performance. In order to facilitate the four-hand …

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.
