The Relationship between Work-Family Role Strain and Parenting Styles in Mothers of Young Children
The relationship between work-family role strain and parenting styles (permissive, authoritarian, and authoritative) was examined. Questionnaires were completed by 45 mothers whose children (ages newborn to three years) were enrolled in early childhood centers in the Dallas-Fort Worth-Denton, Texas, area. Participants were primarily Caucasian, high-income mothers who had attended college. Results indicated no significant relationship between role strain and parenting styles. Open-ended questions revealed insights into mothers' reported role strain. This research may provide employers and professionals who work with families with information to assist mothers in reducing role strain. They may also recognize that parenting style may be independent of a successful balance of work and family.
The Full Armor of God
The Full Armor of God is a musical composition based on the apostle Paul's comparison in Ephesians 6:10-20 between armor for physical combat and armor for spiritual warfare. The instrumentation consists of the following: oboe/English horn, bassoon, two violins, viola, cello, and bass. Texts on Roman armor as well as commentaries and sermons on the scriptures were consulted for the basis of the musical materials. The piece combines imagery and historical associations with abstract renderings of both the physical and the spiritual.
A Comparative Study of School District Expenditures in Texas Since the Enactment of Senate Bill 7
The purposes of this study were to: (a) determine the effects of Senate Bill 7 on expenditures in Texas school districts, (b) compare similarities and differences in expenditures among property-poor, medium-wealth, and wealthy-districts, (c) analyze spending patterns in light of equalization efforts, and (d) provide useful data to researchers in the area of equalization and adequacy.
A Comparison of Elderly Segments on Prepurchase Information Sources
The purpose of this research was to determine if differences exist between the young/old (55-74) and the old/old (75+) regarding external search behavior and the importance of information sources.
The Texas Presidencies : Presidential Leadership in the Republic of Texas, 1836-1845
This thesis examines the letters, proclamations, and addresses of the four presidents of the Republic of Texas, David G. Burnet, Sam Houston, Mirabeau B. Lamar, and Anson Jones, to determine how these men faced the major crises of Texas and shaped policy regarding land, relations with Native Americans, finances, internal improvements, annexation by the United States, and foreign relations. Research materials include manuscript and published speeches and letters, diaries, and secondary materials.
A Study on U.S. Japanese Foreign Trade
This research presents an in depth discussion and analysis on U.S. Japanese foreign trade. It is divided into two parts. The first hypothesis states that the appreciation of the dollar in the early eighties is positively correlated with the U.S. trade deficit, especially with Japan. The second hypothesis states that Friedrich Von Hayek's Theory of Social Order applies to the development of capitalism in that country. This can also be divided into two parts, a) this generation of Japanese consumes, saves, and invests differently than previous generations, and b) Japanese consumption and investment patterns follow U.S. consumption and investment patterns with a lag.
Intelligent Discontent, Agitation, and Progress: A Time-Series Analysis of National Revolts in Central America 1960-1982
Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua have all experienced significant social, economic, and political changes during the 1960s, 1970s, and 1980s. Guatemala, El Salvador, and Nicaragua experienced violent national revolts, while Costa Rica and Honduras did not. I tested a process theory that endeavored to account for the origins and intensity of national revolts in Central America. The analysis was formulated in a most-similar-systems (MSS) design. Pooled cross-sectional time-series regression techniques were employed in order to conform with the MSS variation-finding strategy. The findings supported the conclusion that armed attacks against the state were not random occurrences, but rather, that they may have arisen in response to certain economic and political conditions.
The Predictive Validities, as Measured by Multiple Correlation, of Certain Mathematics Grades and a Test Battery Using Academic Achievement as Criteria
The problem of this study was to determine the predictive validities, as measured by multiple correlation, of certain mathematics course grades and the American College Test (ACT) battery when various achievement criteria were used. This study had a two-fold purpose: (1) to determine measures which could be used effectively to predict academic achievement in college mathematics, and (2) to determine whether the multiple correlation between selected predictors and each criterion were significant.
Programming Common Stimuli to Promote Generalized Question-Asking in a Child with Autism
A 5-year-old child with autism was taught to: (a) ask "What is that?" in the presence of unknown objects and (b) name the objects he did know. Generalization in the presence of the experimenter was probed across four new tasks. The child's performance generalized to the first 3 tasks without additional training. The fourth task required programming of common stimuli before generalization occurred.
Identity Status and Adjustment to Loss Among Adolescents
The purpose of the present investigation was to explore the relationship of the adolescent experience of parental death to the variables of identity formation, adjustment, and coping. The inclusion of adolescents who had experienced parental divorce and those who had not experienced either loss condition allowed for group comparisons.
The Effect of Study Skills Training Intervention on United States Air Force Aeromedical Apprentices
The study examined the effects of a study skills training intervention course on U.S. Air Force Aeromedical Apprentices with five main purposes. The first was to examine the relationship between study skills training and the number of times students required academic interventions outside of normal class time. The second purpose was to examine the relationship between study skills training and end of course averages. The third was to determine the relationship between study skills training and the amount of additional instruction, measured in time, students required. The fourth purpose examined the relationship between study skills training and graduation rates. The final purpose was to recommend areas for further research.
Boulez's Sonatine and the Genesis of His Twelve-tone Practice
This dissertation proposes that the Sonatine broadly unfolds a kinetic structure that stems from the traditional tension-relief model and, consequently, its dependence on tradition proves much deeper than Boulez would acknowledge.
The Use of the Clarinet in Selected Viennese Operas, 1786-1791, With Three Recitals of Selected Works by Brahms, Muczynski, Benjamin, Widor, Hindemith, and Others
In an appendix section, three notable arias have been transcribed for two clarinets, voice, and piano. A further evaluation of Classical period opera orchestration will aid modern performers and musicologists in their understanding of what clarinets and clarinetists were able and expected to do.
Regulation of Escherichia coli pyrBI Gene Expression in Pseudomonas fluorescens
Pseudomonas fluorescens does not appear to regulate the enzymes of de novo pyrimidine biosynthesis at the level of gene expression. Little or no apparent repression of pyr gene expression is observed upon addition of exogenous pyrimidines to the growth medium. The Escherichia coli pyrBI genes for aspartate transcarbamoylase (ATCase) were sized down and cloned into the broad host range plasmid, pKT230. Upon introduction into a P.fluorescenspyrB mutant strain, ATCase showed repression in response to exogenously fed pyrimidine compounds. Thus, it was possible to bring about changes in pyrimidine nucleotide pool levels and in transcriptional regulation of gene expression at the same time.
The Role of Fluency in the Emergence of the Derived Relations of Stimulus Equivalence
Fluent component performances may be more readily available for recombination into more complex repertoires. This experiment considered the stimulus equivalence preparation as a laboratory analog for the co-adduction said to occur in generative instruction. Seven adults received minimum training on 18 conditional discriminations, components of 9 potential stimulus equivalence classes. Training was interrupted periodically with tests to determine whether fluency of original relations predicted emergence of derived relations. Fluency predicted emergence in 2 of 17 instances of emergent derived relations for 4 subjects. One subject demonstrated fluency without derived relations. Training accuracies as low as 58% preceded emergence for 3 subjects. Fluency appears to be neither necessary nor sufficient for derived relations. Fluency's role may be in retention and complex application tasks rather than acquisition of behavioral relations.
Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.
The Separation of Rehabilitation from Production Costs in the Vocational Rehabilitation Workshop
The problem with which this study is concerned is the separation of rehabilitation from production costs in vocational rehabilitation workshops. Within workshops there are those functions and tasks—testing, counseling, and the administration thereof—which clearly are rehabilitative. The costs of these activities, therefore, are solely rehabilitation costs. In the production area of workshop operations, however, where production and rehabilitation efforts are intertwined, two kinds of costs are incurred simultaneously: (l) rehabilitation or training costs and (2) production costs. As yet, no generally accepted procedures exist for separating these joint costs.
The Relationship of Developmentally Appropriate Beliefs and Practices of Greek Kindergarten Teachers
Sixty Greek kindergarten teachers were surveyed regarding their teaching beliefs and practices using the Teachers Questionnaire based on guidelines recommended by the National Association for the Education of Young Children. A Varimax factor analysis produced four factors for the Teacher Belief Scale and five factors for the Instructional Activities Scale. Scores on developmentally appropriate factors were consistently higher than factors classified developmentally inappropriate. Correlation between appropriate beliefs and activities was significant (r = .470); correlation between inappropriate beliefs and practices was significant (r = .475). However, developmentally inappropriate beliefs were also positively correlated with developmentally appropriate practices (r = .537). Developmentally appropriate beliefs were not correlated with inappropriate practices. Results were discussed with possible theoretical and practical implications for future research and teacher development.
Comparative Study of the Bel Canto Teaching Styles and their Effects on Vocal Agility
This thesis examines the historical significance of the vocal methods employed from the middle of the seventeenth century to the beginning of the nineteenth century in what became known as the bel canto era. It provides further exploration into the pedagogical procedures of the bel canto technique through a study of the premier instructors and singers from this period. The resurgence of interest in this tradition is addressed along with its impact on current vocal pedagogy. The vital role that vocal agility played as one of its most distinguishing traits is the primary factor under investigation. A discussion of the bel canto teaching styles in relation to their approach to agility is a major point of inquiry. By maintaining a link between present artists and pedagogues and the old Italian school, it helps the singer understand the historical implications of vocal agility as an integral part of healthy vocal development.
Women in Higher Education Administration: An Analysis for 1983-1998
The objective of this study was to identify if women have made statistically significant increases as top-level administrators in institutions of higher education during the period 1983-98. The research focused on the following areas: (1) Have women made significant increases as administrators during 1983-98? (2) Have women made significant increases in their proportion of total administrators during 1983-98 in the following areas: (a) comprehensive institutions, (b) doctoral institutions, (c) liberal arts institutions, and (d) research institutions? (3) Has the proportion of women administrators in private institutions increased significantly more than the proportion of women administrators in public institutions for 1983-98?
Sampling Plan for Incoming Material Inspection at Sanden
Sanden international, an automobile air conditioning compressor manufacturer, was facing a problem in its incoming material inspection procedures. Although the company had designed and was using its own sampling plan, some managers and supervisors where not confident of its reliability. Sanden recently established a goal for its total number of defects per supplier as one part per million. Achievement of this target required reviews of the existing sampling plan. The purpose of this project was to help Sandra identify the best alternatives for its incoming material inspection procedures. To do that considerations were made about the usefulness of sampling inspections, theoretical aspects of inspection sampling plans were examined, current sampling plans were analyzed and recommendations were made.
Political Culture in West and East Germany at the TIme of Reunification: Revisiting the Civic Culture
Studies of political culture have often focused on the impact of political institutions on political culture in a society. The scientific community has accepted the position that institutions shape beliefs and attitudes among the citizens towards the system they live in. This study tests this hypothesis by using survey data collected during the fall of 1990 in the United States, Great Britain, Italy, West, and East Germany.
Three-dimensional Information Space : An Exploration of a World Wide Web-based, Three-dimensional, Hierarchical Information Retrieval Interface Using Virtual Reality Modeling Language
This study examined the differences between a 3-D, VRML search interface, similar to Cone Trees, as a front-end to Yahoo on the World Wide Web and a conventional text-based, 1-Dinterface to the same database. The study sought to determine how quickly users could find information using both interfaces, their degree of satisfaction with both search interfaces, and which interface they preferred.
Jules Massenet's Musical Prosody Focusing on His Eight Song Cycles And A Collection, Expressions Lyriques: A Lecture Recital, Together with Recitals of Selected Works of W. A. Mozart, F. Schubert, C. Debussy, R. Strauss, D. Argento, V. Bellini, J. Marx, W. Walton, C. Gounod, A. Scarlatti, G. Fauré, J. Rodrigo, H. Wolf, and Others
Jules Massenet's mélodies feature a distinct vocal treatment regarding musical prosody through his eight song cycles, including Poëme d'Avril, Poëme Pastoral, Poëme du Souvenir, Poëme d'Amour, Poëme d'Hiver, Poëme d'un Soir, and Quelques Chansons Mauves, and a collection, Expressions Lyriques. These mélodies show the influence of the trend of salon music and the high-level poetry from the poetic movements of romanticism, Parnassianism, and symbolism. This study deals with Massenet's mélodies relating to the prosody idea, which is conspicuous in his vocal treatment. His melodic styles feature four distinct aspects of vocal treatment including lyrical, recitative or parlando, melodramatic, and déclamation rhythmée, and represent the idea of musical prosody of phonetic, syntactic, and semantic aspects. Massenet's other musical idioms such as harmony, form, and piano treatment, are also closely related to the prosody matter as a semantic aspect, reinforcing the poetic mood and content. In this study, each melodic style related to French versification is examined in detail. The musical analysis regarding the other musical idioms on selected examples presents the semantic feature of prosody idea. The brief review of French versification and opinions regarding the performance are included. Massenet's contribution to the genre of mélodie, with the prose melody and treatment of piano as an equal partner of voice line, is clearly demonstrated. With this contribution, Massenet should be recognized as the most influential composer to the climatic time of French mélodie led by Fauré, and Debussy, and Duparc.
A Qualitative Research Study of How Extended Field Experience Prepares Special Education Teachers of Students with Emotional and Behavioral Disorders
A well-prepared and qualified special education teacher is crucial to the performance of students with emotional and behavioral disorders (EBD). The prominent educators and federal government encourage the use of extended field experiences in preparing qualified special education teachers. The study examined the strengths and weaknesses of extended field experience in terms of the perceptions of the prospective teachers and teachers of students with EBD. Both individual interviews and a focus group were used to collect data. The results revealed that extended field experience benefits prospective teachers in showing the reality of the teachers' world, self-motivation assessment, and professional development. However, there were some improvements that could be made, including more placement selections and more practical knowledge.
Automated Low-cost Instrument for Measuring Total Column Ozone
Networks of ground-based and satellite borne instruments to measure ultraviolet (UV) sunlight and total column ozone have greatly contributed to an understanding of increased amounts of UV reaching the surface of the Earth caused by stratospheric ozone depletion. Increased UV radiation has important potential effects on human health, and agricultural and ecological systems. Observations from these networks make it possible to monitor total ozone decreases and to predict ozone recovery trends due to global efforts to curb the use of products releasing chemicals harmful to the ozone layer. Thus, continued and expanded global monitoring of ozone and UV is needed. However, existing automatic stratospheric ozone monitors are complex and expensive instruments. The main objective of this research was the development of a low-cost fully automated total column ozone monitoring instrument which, because of its affordability, will increase the number of instruments available for ground-based observations. The new instrument is based on a high-resolution fiber optic spectrometer, coupled with fiber optics that are precisely aimed by a pan and tilt positioning mechanism and with controlling programs written in commonly available software platforms which run on a personal computer. This project makes use of novel low-cost fiber optic spectrometer technology. A cost advantage is gained over available units by placing one end of the fiber outdoors to collect sunlight and convey it indoors, thereby allowing the spectrometer and computer to be placed in a controlled environment. This reduces the cost of weatherproofing and thermal compensation. Cost savings also result from a simplified sun targeting system, because only a small pan and tilt device is required to aim the lightweight fiber optic ends. Precision sun-targeting algorithms, optical filter selection, and software to derive ozone from spectral measurements by the spectrometer are a major contribution of this project. This system is a flexible platform ...
Mechanical Properties of Polymer Modified Mortar
The mechanical properties of the polymer-modified mortar are markedly improved over conventional cement mortar. We utilized recycled ABS in powder form and a polymer latex emulsion, polymer percentage ranges from 0 to 25 percent by polymer/cement ratio were investigated. The mechanical properties investigated were compression strength and adhesion strength. Compression strength effects did not have an impact on adhesion strength. Adhesion strength was calculated with pullout testing apparatus designed by the author. Results indicate that recycled ABS had a lower adhesive strength than the acrylic latex emulsion and the base mortar, but did increase in adhesive strength when mixed with maleic-anhydride. The adhesive strength was investigated for a Fiber Reinforced Polymer (FRP) made of an "E" glass fiber that is a continuous strand roving oriented and pre-tensioned longitudinally in an isopthalic polyester matrix material. The FRP rebar was compared to standard steel rebars, and found that the standard steel corrugated rebar had a higher adhesive strength, due to mechanical interlocking. This was clarified by measurements using a smooth steel rebar. Characterization of the polymer-modified mortar was conducted by pore analysis and scanning electron microscopy. Scanning Electron Microscopy was implemented to view the polymer particles, the cement fibrils formed by the hydration, and to prove Ohama's theory of network structure.
The impact of US-China relations on Taiwan's military spending (1966-1992).
Previous research has shown that Taiwan's military spending is affected either by China's military buildup or the US's military pipeline. This study investigates whether it is also true an ongoing US-China relationship has dynamic effects. Three major findings are obtained from the statistical analyses. First and foremost, the level of US-China conflict has a contemporaneous positive effect on Taiwan's military spending. Second, the analyses also indicate that the volatility of US-China relations has negative effects on Taiwan's military spending. This finding suggests that instability in US-China relations will prompt Taiwan to decrease its military spending due to a higher amount of perceived security on the one hand, and Taiwan wants to avoid further provoking China on the other. Third, analyses indicate that an error correction model fares better than a simple budgetary incremental model in explaining the re-equilibrating effects of GNP growth on Taiwan's military spending. Overall, the results demonstrate the interplay of domestic and international constraints and may help to predict what will be the expected military spending when Taiwan's economy changes. I suggest that Taiwan's military spending is likely to be influenced by US-China relations as well as by foreign investment and domestic economic constraints as long as the United States policy toward the Taiwan problem remains unchanged.
The Use of Genetic Polymorphisms and Discriminant Analysis in Evaluating Genetic Polymorphisms as a Predictor of Population
Discriminant analysis is a procedure for identifying the relationships between qualitative criterion variables and quantitative predictor variables. Data bases of genetic polymorphisms are currently available that group such polymorphisms by ethnic origin or nationality. Such information could be useful to entities that base financial determinations upon predictions of disease or to medical researchers who wish to target prevention and treatment to population groups. While the use of genetic information to make such determinations is unlawful in states and confidentiality and privacy concerns abound, methods for human “redlining” may occur. Thus, it is necessary to investigate the efficacy of the relationship of certain genetic information to ethnicity to determine if a statistical analysis can provide information concerning such relationship. The use of the statistical technique of discriminant analysis provides a tool for examining such relationship.
Peter Lieberson's First Piano Concerto: A Buddhist-inspired poetic vision realized through twelve-tone language, other contemporary compositional techniques, together with three recitals of works by Bach, Chopin, Mozart, Albéniz, Grieg, Ginastera and Paderecki
The main objective of this document is to explore the life and spiritual convictions of composer Peter Lieberson, and the creation of his Piano Concerto. Lieberson is a sought after composer who has won many awards and commissions. His works have been premiered and performed by some of the best musical artists of the late twentieth- and early twenty-first-century, such as Peter Serkin, Emmanuel Ax, Yo-Yo Ma, and Pierre Boulez. This study is divided into six chapters. After the Introduction, a biographical summary of Peter Lieberson's life, his spiritual beliefs and compositional style is presented. Chapter II contains background information on the Piano Concerto, along with biographical sketches of Peter Serkin, for whom the work was written, and Seiji Ozawa, music director of the Boston Symphony Orchestra and conductor of both the premier performance and Serkin's recording of the piece. Chapter III is a selective survey of the compositional techniques used in Lieberson's Concerto, in terms of the application of twelve-tone theory and the resulting octatonic, pentatonic, and whole-tone scales. Chapter IV introduces a general overview of the influence of Buddhism as a source of inspiration in the Piano Concerto. Chapter V examines aspects of performance practice issues. Chapter VI provides conclusions. The aim of this study is to further establish Peter Lieberson's stature as an important modern American composer. It is hoped that this study will encourage further research and interest in his works.
Southern Promise and Necessity: Texas, Regional Identity, and the National Woman Suffrage Movement, 1868-1920
This study offers a concentrated view of how a national movement developed networks from the grassroots up and how regional identity can influence national campaign strategies by examining the roles Texas and Texans played in the woman suffrage movement in the United States. The interest that multiple generations of national woman suffrage leaders showed in Texas, from Reconstruction through the ratification of the Nineteenth Amendment, provides new insights into the reciprocal nature of national movements. Increasingly, from 1868 to 1920, a bilateral flow of resources existed between national women's rights leaders and woman suffrage activists in Texas. Additionally, this study nationalizes the woman suffrage movement earlier than previously thought. Cross-regional woman suffrage activity has been marginalized by the belief that campaigning in the South did not exist or had not connected with the national associations until the 1890s. This closer examination provides a different view. Early woman's rights leaders aimed at a nationwide movement from the beginning. This national goal included the South, and woman suffrage interest soon spread to the region. One of the major factors in this relationship was that the primarily northeastern-based national leadership desperately needed southern support to aid in their larger goals. Texas' ability to conform and make the congruity politically successful eventually helped the state become one of NAWSA's few southern stars. National leaders believed the state was of strategic importance because Texas activists continuously told them so by emphasizing their promotion of women's rights. Tremendously adding credibility to these claims was the sheer number of times Texas legislators introduced woman suffrage resolutions over the course of more than fifty years. This happened during at least thirteen sessions of the Texas legislature, including two of the three post-Civil War constitutional conventions. This larger pattern of interdependency often culminated in both sides-the Texas and national ...
Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy
This study investigated the relationship among anxiety, depression, and sleep disturbances and the treatment of these three disorders through neurotherapy. Research suggests that these conditions commonly co-occur in the general population and that central nervous system (CNS) arousal may play a primary role in the development and maintenance of these disorders. Several recent studies suggested that neurotherapy, a biofeedback-based treatment for CNS dysregulation, might be an effective treatment for comorbid conditions, particularly the ones of interest here, depression, anxiety, and sleep disturbances. This investigation used a clinical case-series design to assess pre/post neurotherapy changes on objective measures of anxiety, depression, and sleep and to determine whether changes in anxiety and depression then predict improvements in sleep quality. Data for 23 participants (10 males) were obtained from files of adults (Mage = 40.22 years, SD = 16.20) who received at least 15 neurotherapy sessions (M = 47.83 sessions, SD = 22.23) the University of North Texas Neurotherapy Lab. Matched pair t-tests revealed that symptoms of sleep disturbance, depression, and anxiety showed significant improvements following neurotherapy. Neurotherapy treatment effect sizes generally ranged from moderate to large (d = .414 - .849). Multiple regression analysis found that changes in self-reported anxiety symptoms, but not depressive symptoms, predicted observed improvements in sleep quality (adjusted R2 = .26). Last, the implications and limitations were discussed in relation to neurotherapy practice and the associated research.
La Primavera: Concertino for English Horn and Chamber Orchestra
La Primavera: Concertino for English Horn and Chamber Orchestra is a work in a traditional chamber orchestra instrumentation: single woodwinds (flute, oboe, clarinet, and bassoon), two French horns, trumpet, timpani and strings. A through-composed work of 14 minutes in duration, the Concertino is conceptually based on the idea that spring is not the first of the seasons, but rather the last. As a result, all of its motivic materials are organically linked to one another, and function as paired forces that struggle for supremacy. The introduction of the third motive functions as a motivic synthesis, since it contains intrinsic elements of previous motives. There are several important compositions based on the topic of the seasons among them we find: Vivaldi's Concerto Grosso Le Quatro Staggione, Haydn's oratorio The Seasons, and Piazzola's chamber work Las Estaciones. While researching this topic, the conceptual dilemma of spring as the last season was considered. This became a turning point in the compositional process strong enough to consider the spring as a singular topic of interest. The analysis of this work through Derrida's Deconstruction theory first came to me while reading Rose Rosengerd Subotnick's Deconstructive Variations: Music and Reason in Western Society. The Linguistic approach, was inspired in part by Leonard Bernstein's lecture “The Unanswered Question,” and Jean J. Nattiez's Music and Discourse: Toward a Semiology of Music.
Perceptions of Disaster Professionalism in Mexico: Adding a New Public Management Perspective to Emergency Management
This study investigated the perceptions of emergency managers regarding the degree of emergency management professionalism in Mexico and how it can be improved. The disaster of the Mexico City earthquake of 1985 was used as the starting point for this case study, as the prospects for more-frequent and more-intense disasters lend credence to the need for improved professionalism and, thus, effectiveness among emergency managers in the future. An expansive framework of emergency management professionalism mechanisms (or characteristics) and an additional compilation of new public management components (or values) were devised from the extant literatures found within the respective emergency management and public administration fields. The theory advanced by this study is that by integrating new public management components with emergency management mechanisms, professionalism in Mexico will improve and, thus, emergency managers will become more effective. ualitative field research was the methodology employed and it included interviews with 35 emergency managers in Mexico in corroboration with documentary evidence, to ascertain emergency managers' perceptions of professionalism in Mexico. The findings of this study determined that emergency managers in Mexico are implementing many of the mechanisms of professionalism but fewer new public management components. This study posits that by integrating new public management components with emergency management professionalism mechanisms, professionalism in Mexico will improve and will increase emergency managers' effectiveness.
Information Censorship: A Comparative Analysis of Newspaper Coverage of the Jyllands-Posten Editorial Caricatures in Cross-Cultural Settings
The identification and examination of cultural information strategies and censorship patterns used to propagate the controversial issue of the caricatures in two separate cultural contexts was the aim of this dissertation. It explored discourse used for the coverage of this topic by one newspaper in a restrictive information context and two newspapers in a liberal information context. Message propagation in a restrictive information environment was analyzed using the English daily Kuwait Times from the Middle East; the liberal information environment of the US was analyzed using two major dailies, the New York Times and the Philadelphia Inquirer. The study also concurrently identifies and elaborates on the themes and frames through which discourse was presented exposing the cultural ideologies and premises they represent. The topic was approached with an interdisciplinary position with the support and applicability testing of Chatman's insider-outsider theory within information science and Noelle-Neumann's spiral of silence theory and Herman and Chomsky's propaganda model based in the area of mass communication. The study has also presented a new model of information censorship - circle of information censorship, emphasizing conceptual issues that influence the selection and censorship of information.
Free Radical Chemistries at the Surface of Electronic Materials
The focus of the following research was to (1) understand the chemistry involved in nitriding an organosilicate glass substrate prior to tantalum deposition, as well as the effect nitrogen incorporation plays on subsequent tantalum deposition and (2) the reduction of a native oxide, the removal of surface contaminants, and the etching of a HgCdTe surface utilizing atomic hydrogen. These studies were investigated utilizing XPS, TEM and AFM. XPS data show that bombardment of an OSG substrate with NH3 and Ar ions results in the removal of carbon species and the incorporation of nitrogen into the surface. Tantalum deposition onto a nitrided OSG surface results in the initial formation of tantalum nitride with continued deposition resulting in the formation of tantalum. This process is a direct method for forming a thin TaN/Ta bilayer for use in micro- and nanoelectronic devices. Exposure to atomic hydrogen is shown to increase the surface roughness of both air exposed and etched samples. XPS results indicate that atomic hydrogen reduces tellurium oxide observed on air exposed samples via first-order kinetics. The removal of surface contaminants is an important step prior to continued device fabrication for optimum device performance. It is shown here that atomic hydrogen effectively removes adsorbed chlorine from the HgCdTe surface.
The Effects of Selective Serotonin Reuptake Inhibitors (SSRI) on Auditory Measures in Women
This study examined the relationship between selective serotonin reuptake inhibitor (SSRI) medication and auditory measures in clinically depressed women. Experimental subjects were tested in both a medicated and unmedicated condition. Experimental subjects were compared to a normal control group; additionally intrasubject comparison was made within the experimental group. Test measures included: audiometry, tympanometry, otoacoustic emissions, uncomfortable loudness level, masking level difference, SCAN-A, Synthetic Sentence Identification (SSI), and the low predictability section of the Revised Speech in noise (RSPIN). The unmedicated group scored significantly less favorably than the control group on the following tests; SCAN-A (composite, filtered words, and auditory figure ground), R-SPIN (0MCR condition in both the right and left ears). Additionally, the unmedicated group scored significantly less favorably than the medicated group on the SSI (-20MCR condition right ear only) and of the R-SPIN (0MCR condition right ear only). Other test measures indicated consistent trends but did reach significance.
An investigation of the current status of fund raising activities and training within student affairs divisions in Texas colleges and universities.
The primary focus of this study was to discover the depth of involvement with fundraising by student affairs professionals in Texas. It sought to determine the predominance of chief student affairs officers trained in development and the types of training that they received. Cooperation between student affairs divisions and development offices was also studied and whether there was a correlation between a cooperative relationship and the number of successful fundraising goals. This study includes a review of related literature on student affairs fundraising, a description of the methodology, results of the survey, conclusions, implications, and recommendations that may assist in future decision-making concerning future involvement in fundraising. The surveys were mailed to 149 four-year (public and private) institutions and two-year public institutions in Texas. The senior staff members of both the student affairs office and development office were asked to complete a survey. There was a 60.7% return rate consisting of responses from 72 development offices and 95 student affairs offices for a total of 167 usable responses. The study found that 59% of the student affairs officers had some formal training and/or on the job training. Involvement in fundraising was reported by 62.1% of the chief student affairs officers. Eighteen percent reported that they employed a development officer exclusively for student affairs fundraising, and another 30% had a development officer assigned to student affairs. Most development officers and student affairs officers perceived the other officer as cooperative rather than competitive in raising funds. Recommendations from this study include studying community college fundraising structures separately for more depth, conducting qualitative interviews with student affairs development officers, making a comparison of student affairs offices that have full-time development officers, and comparing the differences in fundraising success between development officers and chief student affairs officers. Recommendations for the professions include resource development ...
Smoothing the information seeking path: Removing representational obstacles in the middle-school digital library.
Middle school student's interaction within a digital library is explored. Issues of interface features used, obstacles encountered, search strategies and search techniques used, and representation obstacles are examined. A mechanism for evaluating user's descriptors is tested and effects of augmenting the system's resource descriptions with these descriptors on retrieval is explored. Transaction log data analysis (TLA) was used, with external corroborating achievement data provided by teachers. Analysis was conducted using quantitative and qualitative methods. Coding schemes for the failure analysis, search strategies and techniques analysis, as well as extent of match analysis between terms in student's questions and their search terms, and extent of match analysis between search terms and controlled vocabulary were developed. There are five chapters with twelve supporting appendixes. Chapter One presents an introduction to the problem and reviews the pilot study. Chapter Two presents the literature review and theoretical basis for the study. Chapter Three describes the research questions, hypotheses and methods. Chapter Four presents findings. Chapter Five presents a summary of the findings and their support of the hypotheses. Unanticipated findings, limitations, speculations, and areas of further research are indicated. Findings indicate that middle school users interact with the system in various sequences of patterns. User groups' interactions and scaffold use are influenced by the teacher's objectives for using the ADL. Users preferred to use single word searches over Boolean, phrase or natural language searches. Users tended to use a strategy of repeating the same exact search, instead of using the advanced scaffolds. A high percent of users attempted at least one search that included spelling or typographical errors, punctuation, or sequentially repeated searches. Search terms matched the DQ's in some instantiation 54% of all searches. Terms used by the system to represent the resources do not adequately represent the user groups' information needs, however, ...
Lucca in the Signoria of Paolo Guinigi, 1400-1430
This study analyzes the once great medieval Tuscan capital of Lucca's struggle for survival at the beginning of the fifteenth century. This was the age of the rise of regional states in Italy, and the expansionistic aims of Milan, Florence and others were a constant challenge to city-states such as Lucca which desired a political and cultural status quo. Yet, it was a challenge that was successfully met; unlike Pisa, Siena, Perugia, and various other major Tuscan cities, Lucca did not succumb to Milanese or Florentine aggression in the early Quattrocento. Why it did not is a major topic of discussion here. One of the means in which the Lucchese faced the new political and military realities of the time was the establishment of a monarchial system of government in the signoria of Paolo Guinigi (r. 1400-1430). The Guinigi Signoria was not characterized by the use of intimidation and violence, but rather by clientage, kinship and neighborhood bonds, marriage alliances, and the general consent of the people. Paolo garnered the consent of the people at first because his wealth allowed him to protect Lucca and its contado to a greater extent than would have been possible otherwise, and because of his family's long ties with the powerful Visconti of Milan; he held it later because he provided the city-state with capable leadership. This study extends the evidence of recent scholars that every Italian Renaissance city was unique based on its particular geography, alliances, civic wealth, and a number of other factors. Lucca in the period of Paolo Guinigi, a monarchy in the setting of one of the traditionally most republican cities of Italy, provides a most interesting example. “Civic humanism,” for example, has a decidedly different slant in Lucca than elsewhere, and is best exemplified in the figure of Giovanni ...
Establishing the utility of a classroom effectiveness index as a teacher accountability system.
How to identify effective teachers who improve student achievement despite diverse student populations and school contexts is an ongoing discussion in public education. The need to show communities and parents how well teachers and schools improve student learning has led districts and states to seek a fair, equitable and valid measure of student growth using student achievement. This study investigated a two stage hierarchical model for estimating teacher effect on student achievement. This measure was entitled a Classroom Effectiveness Index (CEI). Consistency of this model over time, outlier influences in individual CEIs, variance among CEIs across four years, and correlations of second stage student residuals with first stage student residuals were analyzed. The statistical analysis used four years of student residual data from a state-mandated mathematics assessment (n=7086) and a state-mandated reading assessment (n=7572) aggregated by teacher. The study identified the following results. Four years of district grand slopes and grand intercepts were analyzed to show consistent results over time. Repeated measures analyses of grand slopes and intercepts in mathematics were statistically significant at the .01 level. Repeated measures analyses of grand slopes and intercepts in reading were not statistically significant. The analyses indicated consistent results over time for reading but not for mathematics. Data were analyzed to assess outlier effects. Nineteen statistically significant outliers in 15,378 student residuals were identified. However, the impact on individual teachers was extreme in eight of the 19 cases. Further study is indicated. Subsets of teachers in the same assignment at the same school for four consecutive years and for three consecutive years indicated CEIs were stable over time. There were no statistically significant differences in either mathematics or reading. Correlations between Level One student residuals and HLM residuals were statistically significant in reading and in mathematics. This implied that the second stage of ...
Paul Hindemith's Septet (1948): A Look Back to Neue Sachlichkeit
In the early 1920s, Gustav Friedrich Hartlaub created a fine arts movement that began in Weimar, Germany, which questioned artistic Expressionism. In 1923, he formed an art exhibition to display new art works of simplicity that were of his anti-Expressionist goal. This exhibition was termed Neue Sachlichkeit, or New Objectivity, and quickly became associated with all fine arts. Music of Neue Sachlichkeit ideals during the 1920s and 1930s began to exhibit anti-Expressionist concepts of form, neoclassicism and limited instrumentation. Paul Hindemith was among the leading figures of Neue Sachlichkeit music. Although Paul Hindemith's Septet (1948) was composed during his later career, it shows many Neue Sachlichkeit traits found previously in the 1920s and 1930s. Characteristics of limited/mixed instrumentation, neoclassic instrumentation and form, and Baroque counterpoint are found in the Septet. These traits can also be head in earlier Neue Sachlichkeit pieces by Hindemith such as Hin und zuruck, op. 45a (1927), Das Marienleben (1922/23, rev. 1948) and Neues vom Tage (1929). Chapter 2 examines the Neue Sachlichkeit movement within the fine arts. Chapter 3 gives a brief biography of Paul Hindemith with a concentration on his influence of Neue Sachlichkeit music of the 1920s and 1930s. This chapter also relates this period of Hindemith's earlier career with his techniques used in later works, such as the Septet. Chapter 4 discusses how the Septet directly relates to the Neue Sachlichkeit fine arts movement. Chapter 5 gives a general analysis of the Septet. This analysis provides the reader with an understanding of the forms and tonal relationships used in the Septet. This summarizes the neoclassicism of the Septet and shows traits of Neue Sachlichkeit. Chapter 6 concludes with an examination of the mixed instrumentation of the Septet.
Free Radical Induced Oxidation, Reduction and Metallization of NiSi and Ni(Pt)Si Surfaces
NiSi and Ni(Pt)Si, and of the effects of dissociated ammonia on oxide reduction was carried out under controlled ultrahigh vacuum (UHV) conditions. X-ray photoelectron spectroscopy (XPS) has been used to characterize the evolution of surface composition. Vicinal surfaces on NiSi and Ni(Pt)Si were formed in UHV by a combination of Ar+ sputtering and thermal annealing. Oxidation of these surfaces in the presence of either O+O2 or pure O2 at room temperature results in the initial formation of a SiO2 layer ~ 7 Å thick. Subsequent exposure to O2 yields no further oxidation. Continued exposure to O+O2, however, results in rapid silicon consumption and, at higher exposures, the kinetically-driven oxidation of the transition metal(s), with oxides >35Ǻ thick formed on all samples, without passivation. The addition of Pt retards but does not eliminate oxide growth or Ni oxidation. At higher exposures, in Ni(Pt)Si surface the kinetically-limited oxidation of Pt results in Pt silicate formation. Substrate dopant type has almost no effect on oxidation rate. Reduction of the silicon oxide/metal silicate is carried out by reacting with dissociated NH3 at room temperature. The reduction from dissociated ammonia (NHx+H) on silicon oxide/ metal silicate layer shows selective reduction of the metal oxide/silicate layer, but does not react with SiO2 at ambient temperature.
"I Speak, Therefore I Am:" Identity and Self-Construction as Motivation to Engage in Electronic Word of Mouth
To paraphrase an old bromide, "you are what you consume." Consumers derive their sense of self through products, brands, performances and a host of other meaning-laden materials that they consume. The marketing literature has long recognized possessions as an extension of the self-concept. Although hundreds of studies have examined the linkage between consumption and the self, surprisingly few have examined a related phenomenon - the relationship between the self-concept and word of mouth (WOM). A handful of studies have demonstrated the use of WOM to enhance the consumer's self-image, but most extant research focuses on how the act of engaging in WOM is used to build the self-concept. To date there has not been an extensive examination of the process by which WOM transfers the meaning of a product, brand, advertisement or narrative from one consumer to another as part of identity construction. This dissertation attempts to answer the following research questions: 1. Do self-concept and identity motivate consumers to engage in electronic word-of-mouth (eWOM)? 2. Is there a conceptual model to represent the effects of message characteristics, product/brand characteristics and individual personality differences on the self-enhancement value of eWOM and resulting eWOM behaviors? A conceptual model was proposed and, using an experimental research design, hypotheses were tested using structural equation modeling (SEM). The results suggest that self-concept and identity indeed motivate consumers to engage in eWOM, and a number of brand and message traits comprise eWOM's self-enhancement value. This dissertation both contributes to the theoretical understanding of eWOM and assists managers in developing marketing strategy. The use of WOM for identity construction remains an understudied area in marketing when compared to the consumption of products as self-expression. This research provides suggestions for practitioners in harnessing the potential of eWOM as a marketing strategy through message development and targeting of ...
Resident Rights and Electronic Monitoring
The purpose of this exploratory study was to examine resident, family member and staff perceptions of electronic monitoring and their effect on resident rights. The sample consisted of 53 nursing home residents, 104 staff and 25 family members, in the Dallas Fort Worth metroplex, from a nursing facility in which residents utilize video cameras in their rooms (Nursing Facility 1), two nursing facilities that have video cameras in their common rooms areas (Nursing Facility 2 and 3) and a nursing facility that does not utilize video cameras (Nursing Facility 4). The interview questions and self-administered surveys were in regard to the participant's perceptions of electronic monitoring, perceived risks and benefits of video cameras, awareness of resident rights and consciousness of potential risks to resident rights. Data were analyzed using a mixed methods approach using both ATLAS t.i and SAS. Study findings revealed that residents, family members and staff are aware of the potential benefits of electronic monitoring in nursing facilities. While respondents are hesitant to have electronic monitoring in resident rooms, they are interested in utilizing electronic monitoring in common areas. While residents and staff believe that electronic monitoring compromises resident rights, family members believe resident rights are protected. Different types of staff have different perceptions of electronic monitoring. Those staff members that are more directly involved in resident care are less accepting of electronic monitoring compared to staff that have episodic visits with residents. Among staff members, nursing facilities with prior experience with electronic monitoring are less accepting of electronic monitoring. Further studies are needed to enhance this research.
Algebraically Determined Rings of Functions
Let R be any of the following rings: the smooth functions on R^2n with the Poisson bracket, the Hamiltonian vector fields on a symplectic manifold, the Lie algebra of smooth complex vector fields on C, or a variety of rings of functions (real or complex valued) over 2nd countable spaces. Then if H is any other Polish ring and φ:H →R is an algebraic isomorphism, then it is also a topological isomorphism (i.e. a homeomorphism). Moreover, many such isomorphisms between function rings induce a homeomorphism of the underlying spaces. It is also shown that there is no topology in which the ring of real analytic functions on R is a Polish ring.
Perspectives on Cultural Context: The Use of an Online Participatory Learning Environment as an Expansion of the Museum Visit
Technology offers opportunities for museums to expand the ways in which cultural perspectives relevant to objects on display can be exchanged and understood. Multimedia content offered online in an environment with user input capabilities can encourage dialogue and enrich visitor experiences of museums. This action research project using narrative analysis was an effort to develop the use of web technology in museum education practice, with an emphasis on constructivist learning. Concepts including the visitor-centered museum and multiple narratives led the researcher to collaborate with a pre-service art teacher education classroom and a local Hindu community to create content that might better develop understandings of one museum's Hindu sculpture collection that are personal, cultural, and complex.
Factors Influencing BI Data Collection Strategies: An Empirical Investigation
The purpose of this dissertation is to examine the external factors that influence an organizations' business intelligence (BI) data collection strategy when mediated by BI attributes. In this dissertation, data warehousing strategies are used as the basis on which to frame the exploration of BI data collection strategies. The attributes include BI insightfulness, BI consistency, and the organizational transformation attribute of BI. The research population consisted of IT professionals and top level managers involved in developing and managing BI. Data was collected from a range of industries and organizations within the United States. An online survey was used to collect the data to empirically test the proposed relationships. Data was analyzed using partial least square path modeling (PLS). The results of this study suggest that there exists a positive relationship between institutional isomorphism and BI consistency. The results also indicate that there exists a positive relationship between BI consistency and BI comprehensive data collection strategy, and the organizational transformation attribute of BI and BI comprehensive data collection strategy. These findings provide a theoretical lens to better understand the motivators and the success factors related to collecting the huge amounts of data required for BI. This study also provides managers with a mental model on which to base decisions about the data required to accomplish their goals for BI.

The paper is divided into four chapters, each discussing an element of the piece in detail. The introduction presents background information and compositional approach for the composition. Chapters 1 through 4 present detailed information related to the creation of both the electroacoustic music and video elements of the piece. Chapter 4 contains relevant information to the performance of the piece.
Neuronal Network Analyses in vitro of Acute Individual and Combined Responses to Fluoxetine and Ethanol
Embryonic murine neuronal networks cultured on microelectrode arrays were used to quantify acute electrophysiological effects of fluoxetine and ethanol. Spontaneously active frontal cortex cultures showed highly repeatable, dose-dependent sensitivities to both compounds. Cultures began to respond to fluoxetine at 3 µM and were shut off at 10-16 µM. EC50s mean ± S.D. for spike and burst rates were 4.1 ± 1.5 µM and 4.5 ± 1.1 µM (n=14). The fluoxetine inhibition was reversible and without effect on action potential wave shapes. Ethanol showed initial inhibition at 20 mM, with spike and burst rate EC50s at 52.0 ± 17.4 mM and 56.0 ± 17.0 mM (n=15). Ethanol concentrations above 100 -140 mM led to cessation of activity. Although ethanol did not change the shape and amplitude of action potentials, unit specific effects were found. The combined application of ethanol and fluoxetine was additive. Ethanol did not potentiate the effect of fluoxetine.
