In a quasi-experimental field study, two posttraining interventions composed of relapse prevention (RP) strategies were compared and tested for the effects on participant transfer outcomes. Participant retention of training content, skill maintenance, use of relapse prevention strategies, and self-efficacy served as the dependent variables. Self-efficacy was also tested as a mediator between the experimental treatment levels and both participant skill maintenance and participant use of RP strategies. Participants (n = 39) included managers, directors, and supervisors from various departments within a multi-national telecommunications organization located in a large southern city. After participating in a four-hour leadership development training, two of the three groups participated in a 30-40 minute training where they received one of two RP interventions. One intervention included the steps of (1) identifying potential obstacles to positive training transfer, (2) predicting the first lapse to pretraining behavior, and (3) applying relevant coping strategies to thwart a lapse. The alternative RP intervention included the same steps in addition to a goal setting step. Descriminant descriptive analysis was used to test for group differences across the response variables and to identify on which variables the groups differed. Three separate regression equations were used to test for the mediating relationship of …

In this paper, exhaustivity, continuity, and strong additivity are studied in the setting of topological Riesz spaces. Of particular interest is the link between strong additivity and exhaustive elements of Dedekind s-complete Banach lattices. There is a strong connection between the Diestel-Faires Theorem and the Meyer-Nieberg Lemma in this setting. Also, embedding properties of Banach lattices are linked to the notion of strong additivity. The Meyer-Nieberg Lemma is extended to the setting of topological Riesz spaces and uniform absolute continuity and uniformly exhaustive elements are studied in this setting. Counterexamples are provided to show that the Vitali-Hahn-Saks Theorem and the Brooks-Jewett Theorem cannot be extended to submeasures or to the setting of Banach lattices.

The euphonium has been a respected member of military bands, brass bands, and civilian concert (wind) bands since its invention in 1843. These bands were very visible to the public, and often performed popular music of the day. Since then, the euphonium has had occasional use in orchestral works, jazz, and in brass chamber groups as well. However, by the middle of the 20th century, its traditional use as an instrument of the wind band resulted in a prevailing attitude of the music world toward the euphonium as an instrument strictly for that purpose. This attitude, along with changing popular tastes in music, has over time caused professional opportunities for euphoniumists to become very limited. This lack of public expose for the instrument has therefore resulted in people outside of wind band experience being unaware of the euphonium's existence. There have been, however, positive signs in the last thirty years that changes are taking place in prevailing attitudes toward the euphonium. The formation of the Tubists Universal Brotherhood Association (renamed the International Tuba Euphonium Association in 2000) as a supportive professional organization, the emergence of the tuba/euphonium ensemble as chamber music, new solo works by major composers, and the use …

A new hydrophobic hybrid silica film was synthesized by introducing one silicon precursor (as modifiers) into another precursor (network former). Hybrid films have improved properties. Hydrolysis and condensation of dimethyldiethoxysilane (DMDES) (solvent (EtOH) to DMDES molar ratio R = 4, water to DMDES molar ratio r = 4, 0.01 N HCl catalyst) was analyzed using high-resolution liquid 29Si NMR. It was found that after several hours, DMDES hydrolyzed and condensed into linear and cyclic species. Films from triethoxyfluorosilane (TEFS) have been shown to be promising interlayer dielectric materials for future integrated circuit applications due to their low dielectric constant and high mechanical properties (i.e., Young's modulus (E) and hardness (H)). Co-condensing with TEFS, linear structures from DMDES hydrolysis and condensation reactions rendered hybrid films hydrophobic, and cyclic structures induced the formation of pores. Hydrophobicity characterized by contact angle, thermal stability by thermogravimetric analysis (TGA), Fourier transform Infrared spectroscopy (FTIR), contact angle, and dynamic secondary ion mass spectroscopy (DSIMS), dielectric constant determined by impedance measurement, and mechanical properties (E and H) determined by nanoindentation of TEFS and TEFS + DMDES films were compared to study the effect of DMDES on the TEFS structure. Hybrid films were more hydrophobic and thermally stable. …

Dynamic memory management required by allocation-intensive (i.e., Object Oriented and linked data structured) applications has led to a large number of research trends. Memory performance due to the cache misses in these applications continues to lag in terms of execution cycles as ever increasing CPU-Memory speed gap continues to grow. Sophisticated prefetcing techniques, data relocations, and multithreaded architectures have tried to address memory latency. These techniques are not completely successful since they require either extra hardware/software in the system or special properties in the applications. Software needed for prefetching and data relocation strategies, aimed to improve cache performance, pollutes the cache so that the technique itself becomes counter-productive. On the other hand, extra hardware complexity needed in multithreaded architectures decelerates CPU's clock, since "Simpler is Faster." This dissertation, directed to seek the cause of poor locality behavior of allocation--intensive applications, studies allocators and their impact on the cache performance of these applications. Our study concludes that service functions, in general, and memory management functions, in particular, entangle with application's code and become the major cause of cache pollution. In this dissertation, we present a novel technique that transfers the allocation and de-allocation functions entirely to a separate processor residing in …

The purpose of this study was to determine if, after one year of operation, the UNT/Dallas Public Schools Leadership Development Program was progressing in accordance with the goals set out for the program. Questionnaires administered to 26 interns and 10 mentor principals and follow-up focus group interview sessions provided answers to the study's five research questions that explored the following: selection process; how interns' involvement in campus-based decision-making had changed; how mentor principals' perceptions toward interns had changed; and how administrative interns' perceptions of themselves and educational administration had changed. Findings from this study revealed the selection process provided the Dallas Public Schools an opportunity to select teacher-leaders from the district and to include a representative number of minority and women candidates for participation in the program. An area of weakness was seven interns with low GRE scores were admitted through an appeals process at the university. Another weakness revealed the majority of interns had been assigned more duties and responsibilities at the schools, but only 4 of 26 interns were being allowed to participate in any campus-based decision-making processes that could have an impact on school improvements. The study found the role of the mentor principal to be the …

The majority of Web site design literature mainly concentrates on the technical and functional aspects of Web site design. There is a definite lack of literature, in the IS field, that concentrates on the visual and aesthetic aspects of Web design. Preliminary research into the relationship between visual design and successful electronic commerce Web sites was conducted. The emphasis of this research was to answer the following three questions. What role do visual design elements play in the success of electronic commerce Web sites? What role do visual design principles play in the success of electronic commerce Web sites? What role do the typographic variables of visual design play in the success of electronic commerce Web sites? Forty-three undergraduate students enrolled in an introductory level MIS course used a Likert-style survey instrument to evaluate aesthetic aspects of 501 electronic commerce Web pages. The instrument employed a taxonomy of visual design that focused on three dimensions: design elements, design principles, and typography. The data collected were correlated against Internet usage success metrics data provided by Nielsen/NetRatings. Results indicate that 22 of the 135 tested relationships were statistically significant. Positive relationships existed between four different aesthetic dimensions and one single success measure. …

The traditional cante jondo is a song unique to Andalusia as it developed from the "mosaic" of cultures that have inhabited its borders, including Arabs, Jews and Gypsies. The genre expresses the history of the region, reveals the typography of the landscape and cries the tears of its people. "Deep song," the translation for cante jondo, is the forerunner of the flamenco, but it is a communication of a dark soul rather than an exuberant entertainment. The original folk idiom is a medium less concerned with beauty than the cathartic release of pain of every day life. It expresses the soul of Andalusia. This study explores the history and the poetic and musical forms Andalusian cante jondo as the inspiration for the poetry of Federico Garcia Lorca set by Elisenda Fabregas in the song cycle, Five Poems of Garcia Lorca (1992). Lorca felt the validity of "deep song" and he was disturbed that it was being corrupted by commercialism and was afraid it would be lost to posterity. His goal was to preserve the essence of the song and lift it to an artistic plain. He saw folk music as the core of the national musical and literary identity in …

Although federal circuit and district court judges are placed within a federal hierarchy, and receive legal and judicial training that emphasizes the importance of the judicial framework and its structure, such judges are also subjected to other pressures such as the types of litigants within the courtrooms as well as their local political environment. Furthermore, such judges are apt to form their own views about politics and legal policy and are often appointed by presidents who approve of their ideological leanings. Thus, federal courts are caught between competing goals such as their willingness to maximize their preferred legal policy, and their place within the judicial hierarchy. This dissertation applies hierarchy and impact theory to assess the importance of the judicial framework and its socialization, by analyzing both the judicial opinions and votes of federal circuit and district court judges in obscenity cases during a four-decade period (1957-1998). The research presented here finds the influence of higher court precedent to correspond in part with the conception of a judicial hierarchy. An analysis of citations of Supreme Court precedent (Roth v. United States (1957) and Miller v. California (1973)) in lower court majority opinions suggests low levels of compliance: lower courts at …

An increasingly promising and widespread topic of research in distributed computing is the mobile agent paradigm: code travelling and performing computations on remote hosts in an autonomous manner. One of the biggest challenges faced by this new paradigm is security. The issue of protecting sensitive code and data carried by a mobile agent against tampering from a malicious host is particularly hard but important. Based on secure multi-party computation, a recent research direction shows the feasibility of a software-only solution to this problem, which had been deemed impossible by some researchers previously. The best result prior to this dissertation is a single-agent protocol which requires the participation of a trusted third party. Our research employs multi-agent protocols to eliminate the trusted third party, resulting in a protocol with minimum trust assumptions. This dissertation presents one of the first formal definitions of secure mobile agent computation, in which the privacy and integrity of the agent code and data as well as the data provided by the host are all protected. We present secure protocols for mobile agent computation against static, semi-honest or malicious adversaries without relying on any third party or trusting any specific participant in the system. The security of …

Capitalism's success, according to Karl Marx, is based on continued development of new markets and products. As globalization shrinks the world marketplace, corporations are forced to seek both new customers and products to sell. Commodification is the process of transforming objects, ideas and even people into merchandise. The recent growth of the World Wide Web has caught the attention of the corporate world, and they are attempting to convert a free-share-based medium into a profit-based outlet. To be successful, they must change Web users' perception about the nature of the Web itself. This study asks the question: Is there mythic evidence of commodification on the World Wide Web? It examines how the World Wide Web is presented to readers of three national publications-Wired, Newsweek, and Business Week-from 1993 to 2000. It uses Barthes' two-tiered model of myths to examine the descriptors used to modify and describe the World Wide Web. The descriptors were clustered into 11 general categories, including connectivity, social, being, scene, consumption, revolution, tool, value, biology, arena, and other. Wired articles did not demonstrate a trend in categorical change from 1993 to 2000; the category of choice shifted back and forth between Revolution, Connectivity, Scene, and Being. Newsweek …

Critical care nurses work in an environment rich in informative interactions. Although there have been post hoc self-report survey studies of nurses' information seeking, there have been no observational studies of the patterns and content of their on-duty information behavior. This study used participant observation and in-context interviews to describe 50 hours of the observable information behavior of a representative sample of critical care nurses in a 20-bed critical care hospital unit. The researcher used open, in vivo, and axial coding to develop a grounded theory model of their consistent pattern of multimedia interactions. The resulting Nurse's Patient-Chart Cycle describes nurses' activities during the shift as centering on a regular alternation with the patient and the patient's chart (various record systems), clearly bounded with nursing "report" interactions at the beginning and the end of the shift. The nurses' demeanor markedly changed between interactions with the chart and interactions with the patient. Other informative interactions were observed with other health care workers and the patient's family, friends and visitors. The nurses' information seeking was centered on the patient. They mostly sought information from people, the patient record and other digital systems. They acted on or passed on most of the information …

Composition for Arnold Schoenberg is a comprehensible presentation of a musical idea (musikalische Gedanke); the totality of a piece represents the idea. For tonal works, he defines Gedanke as a process of resolving the "tonal relation" or "tonal problem." Contrary to the numerous tonal examples illustrating the notion of Gedanke, Schoenberg hardly expounds on the Gedanke principle for his atonal and twelve-tone repertoires. This study reevaluates Schoenberg's compositional philosophy and aesthetics including Gedanke, comprehensibility, Grundgestalt, and developing variation in light of his compositional practices in Begleitungsmusik zu einer Lichtspielszene, Op. 34. Although Schoenberg denies the existence of a tonal problem and hierarchy among pitches in twelve-tone compositions, the registral placement found in Op. 34 indicates certain functionality assigned to each pitch-class, producing a sense of "departure and return." The approach here elucidates the "idea" of Op. 34, in which the large-scale formal organization unfolds through contextually emphasized tonal relations. This study also explores Schoenberg's concept of the multi-dimensional presentation of a musical idea. Even though Schoenberg's discussion of musical coherence is usually limited to the immediate musical surface, I believe that he was also aware of an extended realization of foreground motives in the sense of Heinrich Schenker's "concealed motivic …

An examination of the influences on twentieth-century wind music would be incomplete without the consideration of composer, organist, pianist, conductor, teacher, and critic Nadia Boulanger (1887-1979). Students from the United States began studying with Boulanger between World War I and World War II, and continued to travel to study with her for over fifty years. The respect awarded this legendary French woman was gained as a result of her effectiveness as a teacher, her influence on the development of each student's unique compositional style, and her guidance of an emerging American musical style. The correlation between the teacher's lessons and the compositional output of her students must be explored. Boulanger did not compose specifically for winds, and she did not encourage her students to compose for the wind symphony. However, this document will outline the influence that this powerful pedagogue exerted over the creation of repertoire by her students by providing insight into the pedagogical style and philosophical foundations of Boulanger as reflected in the literature and by the writings, comments, and compositions of three successful students who composed literature for the wind symphony: Aaron Copland (1900-1990), Leslie Bassett (b. 1923), and Donald Grantham (b. 1947). Three significant works for …

In his song cycle, Chansons madécasses (1926), a chamber work for voice, piano, flute, and cello, Maurice Ravel combines twentieth-century musical experimentation and exoticism with the late nineteenth-century style characteristics present in the vocal elements and instrumentation. Because early twentieth-century music appears to be closely connected to modern concerns, performers may tend to dismiss the style and technique of the early twentieth century as simply "old-fashioned" rather than examine and consider those elements as resources and valuable tools for interpreting and presenting authentic performances. The focus of this research includes a discussion of the historical, social, and textual implications of the music and poetry; a formal musical analysis of the work, including comparisons of an early twentieth-century, mid-century, and late twentieth-century recordings with regard to the use of vibrato and portamento in the voice, cello, and flute; and an examination of Chansons madécasses for elements of authentic Malagasy music and poetry. The paper also suggests methodologies for performance practice which reflect the results of these analyses. The beginnings of the rejection of traditional form - harmonic, rhythmic, and melodic structures - found in the early part of the century began to free composers and performers to explore musical presentations that …

This dissertation on Rachmaninoff's Rhapsody on a Theme by Paganini, Op.43 is divided into four parts: 1) historical background and the state of the sources, 2) analysis, 3) semantic issues related to analysis (discourse), and 4) performance and analysis. The analytical study, which constitutes the main body of this research, demonstrates how Rachmaninoff organically produces the variations in relation to the theme, designs the large-scale tonal and formal organization, and unifies the theme and variations as a whole. The selected analytical approach is linear in orientation - that is, Schenkerian. In the course of the analysis, close attention is paid to motivic detail; the analytical chapter carefully examines how the tonal structure and motivic elements in the theme are transformed, repeated, concealed, and expanded throughout the variations. As documented by a study of the manuscripts, the analysis also facilitates insight into the genesis and structure of the Rhapsody. How Rachmaninoff develops his ideas through several notebooks - including sketches and drafts - is described. Later parts of the dissertation deal with programmatic aspects of the Rhapsody. Related to the composer's significant use of the Dies Irae melody, semantic issues concerning "love and death" are taken into account and closely related …

The reactivity of oxide surfaces and metal-oxide interfaces play an important role in many technological applications such as corrosion, heterogeneous catalysis, and microelectronics. The focus of this research was (1) understanding the effects of water vapor exposure of ultrathin aluminum oxide films under non-ultrahigh vacuum conditions (>10-9 Torr) and (2) characterization of Pt growth modes on ultrathin Ta silicate and silicon dioxide films and the effects of growth modes on adhesion of a Cu overlayer. These studies were conducted with X-ray photoelectron spectroscopy (XPS). Ni3Al(110) was oxidized (10-6 Torr O2, 800K) followed by annealing (1100K). The data indicate that the annealed oxide film is composed of NiO, Al2O3 and an intermediate phase denoted here as "AlOx". Upon exposure of the oxide film at ambient temperature to increasing water vapor pressure (10-6 - 5 Torr), a shift in both the O(1s) and Al(2p)oxide peak maxima to lower binding energies is observed. In contrast, exposure of Al2O3/Al(polycrystalline) to water vapor under the same conditions results in a high binding energy shoulder in the O(1s) spectra which indicates hydroxylation. Spectral decomposition provides further insight into the difference in reactivity between the two oxide films. The corresponding trends of the O(1s)/Ni0(2p3/2) and Al(2p)/Ni0(2p3/2) spectral …

Richard Strauss's Duett-Concertino for Clarinet and Bassoon with Strings and Harp, AV 147 was one of the last works written by this celebrated composer. This double concerto has been largely unrecognized by performers and scholars until a recent surge in recorded performances. Some factors that hinder performances of the Duett-Concertino include unusual scoring and difficult rhythmic passages, as well as a lack of acknowledgement or understanding of the programmatic elements represented in the music. Sketches and letters show that the Duett-Concertino was inspired by a fairytale, which may have been the popular Beauty and the Beast. The programmatic analysis in this study examines the musical gestures of the piece, which, when combined with the cues provided in the sketches and letters, construct a musical interpretation of the fairytale. Recognition of the extra-musical features of the Duett-Concertino is essential for an effective performance and, in turn, creates additional performance possibilities such as narration and choreography.

The problem of this study was to determine whether Kenyan Bible college students who receive instruction using a modified (highly structured) mastery learning model will demonstrate greater achievement in knowledge of Christian Church history as compared to Kenyan Bible college students who receive instruction using a traditional (minimally structured) non-mastery learning model. The subjects were 17 second-year Kenyan Bible college students enrolled in a course on Christian Church history, and they were randomly assigned to the two treatment conditions. The researcher served as instructor for both groups. The experimental group used a textbook, detailed syllabus, 200 page study guide (featuring an advance organizer to provide an ideational scaffolding), and a lesson-development feature (providing an enabling objective, congruent questions, and informative feedback for each lesson segment). The control group used a textbook and a less-detailed syllabus. Both groups shared the same classroom lectures, class discussions, required assignments, examinations, and review of examination items. Five tests of Christian church history were administered, including a pretest, three unit tests, and a comprehensive course examination. Test data were analyzed using a 2 x 5 (treatment x testing occasion) repeated measures analysis of variance (RM ANOVA). The percentage of students performing at mastery level (80% …

Researchers have noted that by providing formal and informal social skills training (SST), the school can become a potential optimal setting that fosters the development of social competence in students with behavioral problems. Indeed, learning to get along with people is one of the most important skills that we can teach students. In order to maximize its effectiveness, SST must be motivating and personally relevant enough for students to want to use the skills. In addition, it must provide opportunities for learned skills to be practiced under varying conditions and in as close to natural situations as possible in order to enhance the transfer of training. The purpose of the study was to investigate the social competence of students aged from six to twelve, diagnosed with emotional/behavioral disorders (E/BD) in a public self-contained school setting, and to increase the students' social competence by using a literature-based method that employs multiage grouping, impersonation, and telecommunications. By providing intensive, literature-based training in a multiage classroom, the SST gave students opportunities to practice skills in a natural, real-life environment and, therefore, increased the likelihood of generalizing these skills in other settings. The employment of impersonation and telecommunications also enhanced students' acquisition of social …

In this dissertation we study the structure of spaces of operators, especially the space of all compact operators between two Banach spaces X and Y. Work by Kalton, Emmanuele, Bator and Lewis on the space of compact and weakly compact operators motivates much of this paper. Let L(X,Y) be the Banach space of all bounded linear operators between Banach spaces X and Y, K(X,Y) be the space of all compact operators, and W(X,Y) be the space of all weakly compact operators. We study problems related to the complementability of different operator ideals (the Banach space of all compact, weakly compact, completely continuous, resp. unconditionally converging) operators in the space of all bounded linear operators. The structure of Dunford-Pettis sets, strong Dunford-Pettis sets, and certain spaces of operators is studied in the context of the injective and projective tensor products of Banach spaces. Bibasic sequences are used to study relative norm compactness of strong Dunford-Pettis sets. Next, we use Dunford-Pettis sets to give sufficient conditions for K(X,Y) to contain c0.

Effectively integrating technology into school requires the presence of informed and visionary leadership. Past research on change in schools demonstrates the importance of the principal to that process. In that research it is obvious that the principal must possess more than skills and knowledge about the change, he or she must also possess leadership skills to lead the campus through the change. Despite this finding, very little research has been attempted to determine the leadership knowledge and skills of principals for technology integration. This study attempts to investigate the technology leadership of high school principals in Texas using the National Educational Technology Standards for Administrators (NETS*A). In addition, this study compares technology leadership among principals who have attended the Technology Leadership Academy with those who have not attended this training. The two questions that guided this study are: (1) What are the technology leadership actions of Texas' high school principals in each of the six technology leadership standards identified by the NETS*A standard document? (2) How are the technology leadership practices of high school principals who participated in the Technology Leadership Academy sponsored by TASA and TBEC different from those who have not participated in the training? Because no existing …

Many, if not most, student trombonists have perhaps had little or no previous experience with "extended techniques"-novel or unconventional modes of sound production. To address this deficiency of experience, this document sets forth a progressive sequence of descriptive explanations and supplementary studies, which are specifically designed to assist trombonists in mastering the particular extended techniques that will prepare them to perform three of the most popular late Twentieth-Century pieces for trombone that include extended techniques-Luciano Berio's Sequenza V, Folke Rabe's Basta, and Mark Phillips' T.Rex. Following the introductory chapter, the body of the document consists of three chapters, each of which deals with one of the three solos, presenting descriptive explanations of relevant extended techniques interspersed with performance commentary (solicited from prominent trombonists) and supplementary studies (composed by the author). The studies presented in each chapter are specifically geared toward mastering the extended techniques as they relate to the music of each particular solo. They are also especially focused toward learning the more difficult passages of music in each solo.

Wayfinding is the process of using one or more tools to move from one location to another in order to accomplish a task or to achieve a goal. This qualitative study explores the process of wayfinding as it applies to locating information in a public library. A group of volunteers were asked to find a selection of items in three types of libraries-traditional, contemporary, and modern. The retrieval process was timed and the reactions of the volunteers were recorded, documented, and analyzed. The impact of various wayfinding tools-architecture, layout, color, signage, computer support, collection organization-on the retrieval process was also identified. The study revealed that many of the wayfinding tools currently available in libraries do not facilitate item retrieval. Inconsistencies, ambiguities, obstructions, disparities, and operational deficiencies all contributed to end-user frustration and retrieval failure. The study suggests that failing to address these issues may prompt library patrons-end users who are increasingly interested in finding information with minimal expenditures of time and effort-may turn to other information-retrieval strategies and abandon a system that they find confusing and frustrating.
