Texas Public School Principals' Application of Procedures in Identification and Prevention of Sexual Harassment

Description: The procedural survey on sexual harassment procedures sent to 300 Texas principals had a response rate of 48.3 %. The mean score on the procedural survey for all 300 principals was 69.30 %. Eighteen research questions were addressed in detail in Chapter 4. Only five showed a significant correlation or effect size. Question 5 asked if there was a correlation between gender and the mean score of the survey instrument regarding sexual harassment procedures. The mean score of women was significantly higher than men. Question 6 asked if there was a correlation between the number of students in a school and the mean score of the survey instrument regarding sexual harassment procedures. This revealed that a significant correlation appeared between principals who worked at larger schools. Question 10 asked if there was a correlation between the location of the school, whether rural, urban, or metroplex and the mean score of the survey instrument. Principals of urban and metroplex schools scored significantly higher. Question 13 asked if there was a correlation between the hours of sexual harassment training attended in the last year and the mean score of the survey instrument regarding sexual harassment procedures. The results of this analysis revealed that a correlation approaching a medium effect size of .237 was present. Question 18 asked if there was a correlation between the total number of hours a principal had attended training and the mean score of the survey instrument. Neither the Pearson's correlation or the Spearman's rho was statistically significant. However, due to the large variation in responses on the sum of hours of training about sexual harassment, it was suspected that there might be a covariate accounting for sub-populations within the principals who participated in the survey. For ages 30-43.5, as the number of total training hours increased, the ...

The Characteristics of Sociological Practitioners: A Social Psychological Examination

Description: Questionnaires were sent by mail and e-mail to 143 members of the Sociological Practice Association. The purpose of the questionnaire was to measure the role expectations as qualities (competencies), role expectations as actions, and role enactments of the respondents'. An additional goal was to examine how respondents perceived their work to be sociological in nature, and how they saw their work as different from the practices of social workers, counselors, and psychologists. The first question that was addressed was, “Do sociological practitioners have clear and unambiguous role expectations for their work as practitioners?” The data showed that most role expectations measured as competencies were clear and unambiguous, and only a few were ambiguous and unclear. The second question addressed was, “Do sociological practitioners perceive their role enactments to differ from other helping professionals such as social workers, counselors, and psychologists?” The data showed that sociological practitioners do perceive their role enactments to be different because of their use of sociological theory and their focus on social structures. The final question asked was, “How do sociological practitioners perceive their work as sociological in theory, methods, or both?” The data showed that sociological practitioners perceive their work as sociological based on their use of sociological theory. Most respondents reported that they used common scientific methods, and few reported the use of psychological theory.

Use of the Beck Depression Inventory in Northern Brazil

Description: The Beck Depression Inventory (BDI) is a popular screening and research instrument for measuring severity of depression. The instrument was translated to Portuguese for use in Brazil in 1979; however, it was not until recently that its psychometric properties have been tested empirically for the Brazilian population. The purpose of the present study was to explore the BDI's psychometric properties in a northern region of Brazil and to test for possible relationships between certain demographic variables and BDI outcomes. Samples used in this study were from an urban area in Roraima, the northernmost state of Brazil. The BDI showed adequate levels of internal consistency in nonclinical and clinical samples. Female respondents had significantly higher scores than male respondents. Those who had lower levels of education, income, or occupational status had significantly higher scores than those with higher levels of these variables. Adolescents had significantly higher scores than adults from all age groups except those from age 19 to 22. No significant difference was found between those who identified themselves as “indigenous” and those who identified themselves as “non-indigenous.” Regression analysis results showed that the combination of gender, education, and age best accounted for the variance in BDI scores. An ANCOVA revealed that clinically depressed adults had significantly higher BDI scores than nonclinically depressed adults. Factor analysis results showed that there were two main factors in the item structure for both female respondents and male and female respondents combined: one factor of mainly cognitive-affective items and the other factor of mainly somatic items. The results were discussed in terms of the future use of the BDI in Brazil.

Lucca in the Signoria of Paolo Guinigi, 1400-1430

Description: 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 ...

Sonata for Piano (1963) by Sergei Michailovich Slonimsky: Musical Analysis and Discussion on Interpretation and Performance

Description: The essay begins with the overview of Russian-Soviet piano music from the second half of the 19th century to the end of the 20th century. Then, biographical information about Sergei Slonimsky and an overview of his major compositions is provided. The majority of the paper focuses on Slonimsky's Sonata for Piano (1963). A brief discussion of the Sonata's compositional history is followed by the formal analysis of the overall structure of the work. Slonimsky's original principle of organization of the music is emphasized: the system of constant interrelation of the main thematic material combined with elements of the sonata-allegro form. In the analysis of the harmonic language of the piece, the composer's extensive use of Russian folk elements such as diatonic melodies, sigh motives, parallel triads, and simultaneous use of the lower third with the major triad is pointed out. The rest of the paper focuses on issues of interpretation and performance. Special notice is given to the problem of incorporating a percussive type of playing with the elements of folk cantilena singing. The paper concludes with the history of Sonata's performances and a discussion of current recordings.

Graduate Professional Training in Christian Education at Dallas Theological Seminary and Alumni Perceptions of Program Quality

Description: This study assessed the quality of graduate professional training in Christian education at Dallas Theological Seminary (DTS) in terms of the perceptions of program alumni. The subjects of the investigation were 780 alumni who graduated from DTS between 1984 and 2000. The Christian Education program was assessed utilizing Daniel Stufflebeam's CIPP model and alumni data collected from a survey instrument. A response rate of 65% (N=504) was achieved. The research procedure employed a non-experimental design methodology for the quantitative component and open-ended questions for the qualitative component. Most results were statistically significant at the .05 alpha level utilizing chi-square goodness-of-fit tests.

An evaluation of job satisfaction among salespersons in a small department store using four psychological measures.

Description: The purpose of this study was to examine the potential of three independent psychological scales (Rotter's Locus of Control, Karasek's Job Content Questionnaire [non-injury job stress], and Rosenberg's Self-Esteem Scale) to predict job satisfaction, as measured by Brayfield and Rothe's Index of Job Satisfaction, among salespersons in a small independent department store in Wichita Falls, Texas. An 82-item survey which examined the dynamics of a salesperson's work life was administered to 20 individuals who were full-time employees of the department store. Demographic data were also gathered although these factors were not entered into the regression analysis. A multiple regression procedure examined the responses of the 20 employees who participated in the study. The R-squared coefficient indicates that 41 percent of the variance in Job Satisfaction was explained by the three predictor measures. A major proportion of this unexplained variance may be in variables outside the scope of this study, e.g., salaries, vacation time, benefits, bonuses, or commissions. Results suggest that the independent variables measured by the Locus of Control Scale and the Job Content Questionnaire in combination were the best predictors of job satisfaction with a significance level of .01. The single best predictor was the Job Content Questionnaire, significant at .03. The three instruments (Locus of Control, Self-Esteem, and Job Content Questionnaire) which comprised the independent variables, reached a significance level of .03 in their prediction of job satisfaction (Brayfield-Rothe Index of Job Satisfaction). Study results indicate that a majority of the employees in the sample population were satisfied with their jobs and with the leadership style manifested by the store manager. In addition, job security was believed to be satisfactory. Inasmuch as there is a void in the literature regarding personal characteristics of salespersons as variables that interact with job satisfaction, comparisons of the findings of this research ...

Marxian and Weberian theory as explanations of the effects of industrialization on town development: A case study; Denison, Texas.

Description: While a great deal of historical literature has concentrated on the effects of industrialization on town development, most of the accounts relate to the introduction of industrialization into an established town. This study attempts to analyze, in sociological terms, the effects of industrialization (in this case, the emergence of the railroad) on the social structure of Denison, Texas which was created by industrialization. It is an attempt to combine Marxian and Weberian theory to produce a multi-dimensional theory that can explain town development without the usual economic bias as evident in most contemporary theory. This study proceeds on the assumption that the social order of a newly formed community is not based solely on economic factors. While economic considerations were important for the town of the study, social stability of the town was maintained by other “non-economic” elements. The purpose of the study is to construct a composite theory that can be utilized to analyze town development. The thrust is not the creation of new theory, rather it attempts to combine existing “classical” theories to present a balanced and, to an extent, “objective” explanation of community development. Adding the social aspects of Weber's theory to Marx's theory results in a theory that limits the economic bias associated with pure Marxian theory.

Molecular cloning and analysis of the genes for cotton palmitoyl-acyl carrier protein thioesterase (PATE) and Δ-12 fatty acid desaturase (FAD2-3) and construction of sense and anti-sense PATE plasmid vectors for altering oilseed composition of transgenic cotton plants.

Description: A cotton PATE cDNA clone has a 1.7-kb insert with an coding region for 410 amino acids, lacking codons for the three N-terminal amino acids. The predicted amino acid sequence of the PATE preprotein has a characteristic stromal-targeting domain and a 63% identity to the Arabidopsis FatB1 thioesterase sequence. A cotton genomic clone containing a 17.4-kb DNA segment was found to encompass a palmitoyl-ACP thioesterase (FatB1) gene. The gene spans 3.6 kb with six exons and five introns. The six exons are identical in nucleotide sequence to the open reading frame of the corresponding cDNA, and would encode a preprotein of 413 amino acids. The preprotein is identified as a FatB thioesterase from its deduced amino acid sequence similarity to those of other FatB thioesterase preproteins. A 5'-flanking region of 914 bp was sequenced, with the potential promoter/enhancer elements including basic helix-loop-helix elements (E box). Alkaline blot hybridization of cotton genomic DNA suggests the presence at least two FatB1 thioesterase genes in cotton. Four plasmid constructs for both constitutive and seed-specific anti-sense RNA suppression and gene-transgene co- suppression of PATE gene expression were successfully generated. Two overlapping cotton genomic clones were found to encompass a Δ-12 fatty acid desaturase (FAD2-3) gene. The continuous FAD2-3 coding region is 1,155 bp and would encode a protein of 384 amino acids. The FAD2-3 gene has one large intron of 2,967 bp entirely within its 5'-untranslated region. Several potential promoter/enhancer elements, including several light responsive motifs occur in the 5'-flanking region. Yeast cells transformed with a plasmid construct containing the cotton FAD2-3 coding region accumulate an appreciable amount of linoleic acid (18:2), not normally present in wild-type yeast cells, indicating that the gene encodes a functional FAD2 enzyme.

Detecting the Presence of Disease by Unifying Two Methods of Remote Sensing.

Description: There is currently no effective tool available to quickly and economically measure a change in landmass in the setting of biomedical professionals and environmental specialists. The purpose of this study is to structure and demonstrate a statistical change-detection method using remotely sensed data that can detect the presence of an infectious land borne disease. Data sources included the Texas Department of Health database, which provided the types of infectious land borne diseases and indicated the geographical area to study. Methods of data collection included the gathering of images produced by digital orthophoto quadrangle and aerial videography and Landsat. Also, a method was developed to identify statistically the severity of changes of the landmass over a three-year period. Data analysis included using a unique statistical detection procedure to measure the severity of change in landmass when a disease was not present and when the disease was present. The statistical detection method was applied to two different remotely sensed platform types and again to two like remotely sensed platform types. The results indicated that when the statistical change detection method was used for two different types of remote sensing mediums (i.e.-digital orthophoto quadrangle and aerial videography), the results were negative due to skewed and unreliable data. However, when two like remote sensing mediums were used (i.e.- videography to videography and Landsat to Landsat) the results were positive and the data were reliable.

Working Whiteness: Performing And Transgressing Cultural Identity Through Work

Description: Early in Richard Wright's Native Son, we see Bigger and his friend Gus “playing white.” Taking on the role of “J. P. Morgan,” the two young black men give orders and act powerful, thus performing their perceived role of whiteness. This scene is more than an ironic comment on the characters' distance from the lifestyle of the J. P. Morgans of the world; their acts of whiteness are a representation of how whiteness is constructed. Such an analysis is similar to my own focus in this dissertation. I argue that whiteness is a culturally constructed identity and that work serves as a performative space for defining and transgressing whiteness. To this end, I examine work and its influence on the performance of middle class and working class whiteness, as well as how those outside the definitions of whiteness attempt to “play white,” as Bigger does. Work enables me to explore the codes of whiteness and how they are performed, understood, and transgressed by providing a locus of cultural performance. Furthermore, by looking at novels written in the early twentieth century, I am able to analyze characters at a historical moment in which work was of great import. With the labor movement at its peak, these novels, particularly those which specifically address socialism, participate in an understanding of work as a performative act more than a means to end. Within the context of this history and using the language of whiteness studies, I look at how gendered whiteness is transgressed and reinforced through the inverted job-roles of the Knapps in Dorothy Canfield's The Home-Maker, how work can cause those who possess the physical attributes of whiteness to transgress this cultural identity, as the Joads in The Grapes of Wrath demonstrate, and how the ascribed identities as non-white for Sara in The ...

A Content Analysis of Reading Software Commercially Available for Pre-K to 3rd Grade Children.

Description: The purpose of this qualitative study was to investigate the content and characteristics of the currently available commercial reading software for Pre-K through third grade children. The design of the study was a content analysis. Based on the evaluation rubric established by the researcher, ten commercial reading software were selected to be analyzed. By reviewing and transcribing, the data were obtained, and then coded, categorized, and interpreted. The findings from the analysis revealed that all reading software programs offered exercised for practicing basic phonics skills; the alphabetic principle, letter-sound association, word knowledge, sentence building, and reading comprehension. Depending on the software developers, phonics-based practice was presented in two ways; separate skill-based practice emphasis and storybook-reading emphasis. All software programs utilized drill-and-practice, direct instruction and mastery learning methods and utilized gaming strategies to motivate and engage the learners. Multimedia technology was used to make the software more appealing. All reading software programs were developed on the perspectives that view learning to read as the continuum of a child's oral language development and background experience about words. It is recommended that parents and teachers review and select the software based on reliable information sources, use the software as supplementary practice based on the learning objectives identified and individual student needs.

Mentoring the first-year superintendent in Texas public schools.

Description: This study determined what mentoring experiences first-year superintendents have had and what they need from a mentoring relationship. Structured interviews and field notes were used in this qualitative study focused on Texas first-year superintendents' perceived needs from mentors. Three patterns of mentoring relationships were found: 1) no mentor in the first year, 2) mentor-protégé relationship - those who developed mentoring relationships early in a career with a more senior person in the same school system, and 3) mentoring relationships of convenience - young relationships which developed outside the same system. Skills and knowledge areas novice superintendents identified as critical for mentor assistance were school finance, development of effective relationships with groups that have expectations of the superintendent while also improving student achievement, and working within the politics of the position. Mentor characteristics novice superintendents considered necessary for a positive effect on job success include: trustworthiness, confidentiality, empathy, encouraging, active listening, and integrity. An attitude in which the mentor problem solved with the protégé, and did not give an immediate solution was displayed. Mentors actively and frequently initiated contact. Ideas were freely exchanged, giving the protégé undivided attention while not making the protégé feel inferior. The effects that previous mentoring experiences had on novice superintendents influenced whether they chose to mentor another person. Most reported seeking or engaged in a new mentoring relationship. Differences in areas where help was needed among first-year superintendents associated with district size were reported. Assistance in finance was needed regardless of district size, gender, or ethnicity. Superintendents in small districts reported needing assistance in specific skill and knowledge areas. Those in larger districts reported mentor assistance in problem-solving processes to accomplish a task. Differences in needs of first-year superintendents based on gender or ethnicity were identified but generalizations could not be made due to small numbers. ...

Autoradiographic Localization of Carbachol-Induced Second Messenger Response in the Rat Spinal Cord Following Inflammation.

Description: This study examined central mechanisms of persistent pain using an autoradiographic technique to localize phosphoinositide hydrolysis (PI) in the rat spinal cord dorsal horn. The lateral half of laminae I-II showed the highest levels of baseline PI turnover and carbachol-stimulated PI turnover in normal animals as well as after inflammation. Inflammation resulted in increased baseline PI turnover in this region of the ipsilateral (76%) and contralateral (65%) dorsal horns. Carbachol increased PI turnover in this region in normal rats (55%) and following inflammation (ipsilateral: 46%, contralateral: 45%). The absolute magnitudes of these increases were 1.85, 2.71, and 2.51 nCi/mg, respectively. The results of this study demonstrate the involvement of PI turnover in neural mechanisms of persistent pain, and provide evidence for the involvement of cholinergic systems in this process. Because spinal cholinergic systems have been reported to be anti-nociceptive, the present results appear to reflect an upregulation of anti-nociceptive activity in response to inflammation. Thus, the spinal cholinergic system may be a regulatory site within the anti-nociceptive pathway, and may provide an attractive target for the development of new therapeutic agents.

Gregory the Great: Exegesis and Audience

Description: The aim of this research was to trace the stages in Gregory's career, and the writings he produced during each of them, in order to examine his interest in biblical interpretation, and to link the form and content of his exegesis with the audiences which he was attempting to reach. Gregory's Old Testament homilies, the "Homilies on the Gospels," the "Pastoral Rule" and the "Dialogues" differ considerably one from another in literary form, in content, and in purpose. There were marked changes in Gregory's life from his first commitment to asceticism in the mid 570's, to his death as bishop of Rome in 604. Attention would be given concentrated on his explicitly exegetical writings: the Pastoral Rule and the Dialogues will be considered with the limited aim of assessing their relationship to his exegesis, in the Introduction, the main developments in Western biblical studies in the two centuries before Gregory will be sketched in broad outline, in order to establish a terminology for exegetical literary forms, and to draw attention to the forms which Gregory chose to adopt.

Using Financial Rankings to Identify Characteristics of Libraries Serving Highly Profitable Private Law Firms

Description: This purpose of this study was to develop evidence of a relationship between law libraries and private law firm profitability for law library administrators to use when making strategic decisions that influence the value of their libraries. The highest ranked administrator at each private law firm listed on the 2008 Am Law 200 was invited to complete an online benchmarking survey. The adjusted sample population totaled 179 firms. Fifty-one valid surveys were completed for a 28.5% response rate. Descriptive and statistical analyses were conducted using 26 independent variables (law library characteristics) and a single dependent variable, Revenue per Equity Partner, developed from data published for the Am Law 200. The most significant contributions of this study are: development of important law library financial and return on investment benchmarks; a listing of characteristics that have been empirically shown to impact law firm productivity; identification of optimum reporting structure for the law library administrator. Six characteristics positively impact Revenue per Equity Partner: to whom the library Administrator reports, number of library staff per library, number of Library staff per library, range in hourly bill rate for library staff time, practice areas most often supported. Two monetary measures were also established. The cost benefit of an Am Law library to its firm is $1.00 : $1.68. Each Am Law Library staff member is worth $295,000 in Revenue per Equity Partner to a firm. Law library practitioners can use the results to support evidenced-based strategic decision making in the administration of any private law firm library. Faculty and students in law librarianship programs will have a greater understanding of how to manage law libraries and collections to provide maximum value to their law firms. Benefits to library and information science research include validation of the research design and benchmarking as a theoretical framework for ...

Anxiety, Depression, and Sleep Disorders: Their Relationship and Reduction with Neurotherapy

Description: 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.

Information Literacy Skills in the Workplace: A Study of Police Officers

Description: Information literacy has become more important as more information is produced and communication has become easier. Better information skills are vital for individuals working in governmental organizations as well as in the business sector. Employees are expected to be confident and competent in interacting with information in their workplaces in order to deliver better service to customers and to the public. This study examines the differences in information literacy skills (ILS), computer literacy skills (CLS), and frequencies of use of information sources (FIS) among police officers, based on their socio-demographic characteristics, namely education, departmental affiliation, ranks, and experience. Information literacy process models developed in an educational environment are combined to explore information literacy process in the workplace. Bivariate and multivariate analyses indicated significant differences of ILS and CLS based on education, departmental affiliation, and ranks but no difference for experience. In addition, there were differences of FIS for all demographic variables except departmental affiliation. The findings of the study may guide both future researchers in the process of developing new models in understanding information literacy process and the managers in police organizations in planning better training programs by considering information and computer literacy skills and use of information sources of police officers.

The Effects of the CACREP Standards on the Development of Counseling Skills

Description: This study was designed to measure the effectiveness of accreditation standards (specifically, CACREP Standards for counselor education programs) on the development of counseling skills. A measure of counseling skill (The Counselor Rating Form-Short Version) was used to measure the counseling skills of counselor trainees from various masters programs. These students were enrolled in a doctoral program in counselor education and were taking their first semester practicum. A T-Test of Independent Means revealed that the student counselors from CACREP accredited masters programs scored significantly higher on the CRF-S than did students from non CACREP accredited programs. These students generally had higher levels of counseling skill as judged by this measure. Given the convenience of the sample and its size, results must be analyzed carefully. These results do, however, seem to suggest the necessity of further study. There are several conclusions that may be reasonably drawn from these results. The emphasis that the CACREP Standards place on the supervised experience may account for the difference in skill levels between the two groups. Prior research and student self-report support this theory. The fact that these requirements are daunting to unaccredited programs suggests a gap in experiential learning between the two groups.

An examination of computer anxiety related to achievement on paper-and-pencil and computer-based aircraft maintenance knowledge testing of United States Air Force technical training students.

Description: The purpose of this study was to determine whether varying levels of computer anxiety have an effect on computer-based testing of United States Air Force technical training students. The first chapter presents an overview of computer-based testing, defines key terms, and identifies questions addressed in the research. The rationale for conducting this study was that little research had been done in this area. The second chapter contains a review of the pertinent literature related to computer-based testing, computer anxiety, test reliability, validity, and gender differences in computer use. Due to the lack understanding concerning any effects of computer anxiety on computer-based testing, this has been a worthwhile topic to explore, and it makes a significant contribution to the training field. The third chapter describes the qualitative research methodology used to conduct the study. The primary methodology was an analysis of variance comparison for groups of individuals who displayed high or low computer anxiety to their respective mean computer-based or paper-based aircraft maintenance knowledge testing scores. The research population consisted of United States Air Force aircraft maintenance craftsmen students attending training at Sheppard Air Force Base, Texas. The fourth chapter details the findings of the study. The findings indicate that there was no significant difference between the groups of students rated with high computer anxiety and low computer anxiety while testing with computers. Additionally, no significant differences were detected while testing alternative hypotheses covering differences between groups of students rated with high computer anxiety and low computer anxiety testing by traditional paper-and pencil methods. Finally, a reference section identifying the literature used in the preparation of this dissertation is also included.

Burying the War Hatchet: Spanish-Comanche Relations in Colonial Texas, 1743-1821

Description: This dissertation provides a history of Spanish-Comanche relations during the era of Spanish Texas. The study is based on research in archival documents, some newly discovered. Chapter 1 presents an overview of events that brought both people to the land that Spaniards named Texas. The remaining chapters provide a detailed account of Spanish-Comanche interaction from first contact until the end of Spanish rule in 1821. Although it is generally written that Spaniards first met Comanches at San Antonio de Béxar in 1743, a careful examination of Spanish documents indicates that Spaniards heard rumors of Comanches in Texas in the 1740s, but their first meeting did not occur until the early 1750s. From that first encounter until the close of the Spanish era, Spanish authorities instituted a number of different policies in their efforts to coexist peacefully with the Comanche nation. The author explores each of those policies, how the Comanches reacted to those policies, and the impact of that diplomacy on both cultures. Spaniards and Comanches negotiated a peace treaty in 1785, and that treaty remained in effect, with varying degrees of success, for the duration of Spanish rule. Leaders on both sides were committed to maintaining that peace, although Spaniards were hampered by meager resources and Comanches by the decentralized organization of their society. The dissertation includes a detailed account of the Spanish expedition to the Red River in 1759, led by Colonel Diego Ortiz Parrilla. That account, based on the recently discovered diary of Juan Angel de Oyarzún, provides new information on the campaign as well as a reevaluation of its outcome. The primary intention of this study is to provide a balanced account of Spanish-Comanche relations, relying on the historical record as well as anthropological evidence to uncover, wherever possible, the Comanche side of the story.

Non-Linear and Multi-Linear Time in Beethoven's Opus 127: An Analytical Study of the "Krakow" Sketch Materials

Description: Beethoven's complex manipulation of formal structures, especially his tendency to build important connections and transformative continuities between non-adjacent sections of musical works, may be seen to function as an attempt to control and sometimes to distort the listener's perception of both the narrative process of musical directionality, as well as the subjective interpretation of time itself. Temporal distortion often lies at the heart of Beethoven's complex contrapuntal language, demonstrated equally through the composer's often enigmatic disruption of phrase-periodic gestures, as well as by occasional instances of overtly incongruous temporal shifts. The "Krakow" collection of compositional sketches for Beethoven's String Quartet in E-Flat, Op. 127, provides a number of instances of "non-linear" or "multi-linear" musical continuity. The term "Krakow" sketches, when referenced in this dissertation, specifically designates the group of Beethoven manuscripts possessed by the Biblioteka Jagiellońska in Krakow, Poland, but which formerly were held by the Royal Library in Berlin. Structural voice-leading analyses are provided for selected portions of the "Krakow" collection; these analyses are then compared to voice-leading graphs and analytical reductions of the corresponding material from Beethoven's published versions of the same musical passages. In some cases the sketches supply almost complete texts, for which critical transcriptions are included as extended examples within the dissertation. The primary analytical technique applied to both compositional sketches as well as to complete musical texts derives from Heinrich Schenker's theory of structural voice-leading and graphical reduction. An important method of critical assessment, from which a number of theoretical arguments are developed, is the contention that Beethoven's contrapuntal language, at least in regard to the op. 127 String Quartet, relies heavily upon a temporal distortion of both form and phrase-periodic gestures, requiring the listener to actively re-construct the continuity of Beethoven's subjective formal archetypes.

Algebraically Determined Rings of Functions

Description: 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.

Factors Influencing BI Data Collection Strategies: An Empirical Investigation

Description: 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.
