When interpreter Toussaint Charbonneau, a French Canadian fur trader living among the Hidatsas, and his Shoshone Indian wife, Sacagawea, joined the Lewis and Clark expedition in 1804, they headed into country largely unknown to them, as it was to Thomas Jefferson's hand-picked explorers. There is little doubt as to the importance of Sacagawea's presence on the journey. She has become a near-legendary figure for her role as interpreter, guide, and "token of peace." Toussaint, however, has been maligned in both fiction and nonfiction alike—Lewis himself called him “a man of no peculiar merit.” W. Dale Nelson offers a frank and honest portrayal of Toussaint, suggesting his character has perhaps been judged too harshly. He was indeed valuable as an interpreter and no doubt helpful with his knowledge of the Indian tribes the group encountered. For example, Toussaint proved his worth in negotiations with the Shoshones for much-needed horses, and with his experience as a fur trader, he always seemed to strike a better bargain than his companions. During the expedition Sacagawea gave birth to a son, Jean Baptiste. With her death in 1812, Clark assumed custody of her son and Toussaint returned to his life on the upper Missouri. Surviving …

Guided by the life course perspective, this study examined the frequency of caregiving provided by older adults to kin and non-kin. A telephone survey produced a random sample of adults 60 years of age and older, which was predominantly White, with higher income and education levels (n = 278). Bivariate and multivariate analyses tested the impact of demographic characteristics and other variables, conceptualized as physical, human, and social capital, on the frequency of caregiving. Gender, age, health, limitations, education, income, household composition, social contact, and reciprocity were analyzed in multinomial logistic regressions. Caregiving was defined as care provided to sick or disabled persons, with frequency of providing care classified as often, sometimes, and never. The majority of older adults provided at least some care to others over a one-year period, with almost one-third doing so often and only one-quarter never doing so. Most provided care to more than one person, with over one-quarter providing care to multiple friends only. Age failed to predict caregiving involvement when physical and social capital variables were considered. The odds of often providing care are higher for women, although gender did not predict those who never provided care. Having at least some college only significantly …

This thesis is an examination of "paranoid conspiracy" films, a film noir subgenre that emerged in mainstream American cinema in the early 1970s and turns on vast, shadowy conspiracies located within U.S. "power structures" (government agencies, the military, the media) and directed against the American public. Specifically, it focuses on the emergence of these films in the 1970s, their almost complete disappearance during the Reagan presidency, and subsequent reemergence in the early 1990s. Placing representative texts in the context of U.S. political and social reality of the last three decades, it analyzes the relationship between the conspiracy theory genre, the "crisis of confidence" in the American society, and the process of formation of American national identity.

The novel tells the stories of 24-year-old Robin, her Aunt Paula, and Paula's boyfriend, Sam.

James Sellars has established himself as one of America's foremost composers whose eclectic style reveals a wealth of influences. His artistic combination of various traditional and avant-garde techniques, along with his sensitive and expert craftsmanship has earned him an important position in contemporary American music. Sellars' compositional styles have encompassed neo-Romanticism, in his early days, through post-serialism and Dada to an eclectic, post-Romantic style utilizing popular elements including electro-acoustic techniques. His extensive catalog of over 150 compositions includes works for orchestra, opera, chorus, dance, chamber, voices with ensemble, solo voice, piano, instrumental solos, band, and media. Sellars' compositions for piano solo span a 38-year period and total 17 works, the most important of which are his six one-movement sonatas, which represent, according to Sellars, "a journey from modernism to post-modernism." Their value lies in their eclectic stylistic approaches, artistic nd technical challenges, and pianistic effectiveness. The first three sonatas, incorporating post-serial elements, fall into a modernist stylistic stance while numbers four through six, in postmodern style, contrast one another drastically. Sonata Brasileira, recalls the broad sweeping gestures of the Romantic period; Sonata V reveals the influence of the absurdist Dada movement; and the last sonata Patterns on a Field, blends …

The purpose of this study was to identify perceived barriers to faculty participation in distance education courses in a 4-year university. The literature review was divided into four general areas, each of which may act as a barrier to faculty participation; training, administrators, rewards/compensation, and faculty characteristics/demographics. The research population consisted of 570 faculty and 59 administrators from the eight UNT schools/colleges. Dr. Kristin Betts developed the survey instrument in 1998 for similar research conducted at the George Washington University. Analysis of the collected data revealed that there was no statistically significant relationship found between faculty characteristics and faculty participation in distance education. Faculty participants and administrators disagreed on which factors, from a list of 34 items, had motivated faculty to participate in distance education. Nonparticipants and administrators disagreed on which of the factors, if not available, would be barriers to faculty participation in distance education. Participants and nonparticipants disagreed regarding the level to which selected rewards and compensations had motivated faculty to participate, and the lack of which would inhibit faculty participation in distance education. Finally, 71% of the participants had participated or planned to participate in distance education training compared to only 33% of the nonparticipants. It is …

A mobile ad hoc network (MANET) is a collection of mobile platforms or nodes that come together to form a network capable of communicating with each other, without the help of a central controller. To avail the maximum potential of a MANET, it is of great importance to devise a routing scheme, which will optimize upon the performance of a MANET, given the high rate of random mobility of the nodes. In a MANET individual nodes perform the routing functions like route discovery, route maintenance and delivery of packets from one node to the other. Existing routing protocols flood the network with broadcasts of route discovery messages, while attempting to establish a route. This characteristic is instrumental in deteriorating the performance of a MANET, as resource overhead triggered by broadcasts is directly proportional to the size of the network. Bounded-dynamic source routing (B-DSR), is proposed to curb this multitude of superfluous broadcasts, thus enabling to reserve valuable resources like bandwidth and battery power. B-DSR establishes a bounded region in the network, only within which, transmissions of route discovery messages are processed and validated for establishing a route. All route discovery messages reaching outside of this bounded region are dropped, thus …

This study investigates the correlation between students' learning styles, computer competency and student satisfaction in Web-based distance learning. Three hundred and one graduate students participated in the current study during the Summer and Fall semesters of 2002 at the University of North Texas. Participants took the courses 100% online and came to the campus only once for software training. Computer competency and student satisfaction were measured using the Computer Skill and Use Assessment and the Student Satisfaction Survey questionnaires. Kolb's Learning Style Inventory measured students' learning styles. The study concludes that there is a significant difference among the different learning styles with respect to student satisfaction level when the subjects differ with regard to computer competency. For accommodating amd diverging styles, a higher level of computer competency results in a higher level of student satisfaction. But for converging and assimilating styles, a higher level of computer competency suggests a lower level of student satisfaction. A significant correlation was found between computer competency and student satisfaction level within Web-based courses for accommodating styles and no significant results were found in the other learning styles.

The primary goal of this thesis is to provide a comparative analysis of the institutional and organizational mechanisms designed to monitor and control political corruption at the national level. The paper will provide comparisons of these arraignments and control systems across three nations. The thesis will identify differences across countries in terms of organizational and institutional political corruption control mechanisms, and use the CPI index to suggest and identify those control mechanisms that appear to be present in nations with low CPI measurements. Finally, the thesis will conclude with the discussion concerning the future prospects for controlling political corruption in Turkey based on the comparative analysis described above.

Critics and audiences alike have neglected the idea of Wilde as a precursor to Beckett. But I contend that a closer look at each writer's aesthetic and philosophic tendencies-for instance, their interest in the fluid nature of self, their understanding of identity as a performance, and their belief in language as both a way in and a way out of stagnancy -will connect them in surprising and highly significant ways. This thesis will focus on the ways in which Wilde prefigures Beckett as a dramatist. Indeed, many of the themes that Beckett, free from the constraints of a censor and from the societal restrictions of Victorian England, unabashedly details in his drama are to be found residing obscurely in Wilde. Understanding Beckett's major dramatic themes and motifs therefore yields new strategies for reading Wilde.

Secure communication is the primary challenge in today's information network. In this project an efficient secret key agreement protocol is described and analyzed along with the other existing protocols. We focus primarily on Leighton and Micali's secret-key agreement without the use of public-key encryption techniques. The Leighton-Micali protocol is extremely efficient when implemented in software and has significant advantages over existing systems like Kerberos. In this method the secret keys are agreed upon using a trusted third party known as the trusted agent. The trusted agent generates the keys and writes them to a public directory before it goes offline. The communicating entities can retrieve the keys either from the online trusted agent or from the public directory service and agree upon a symmetric-key without any public-key procedures. The principal advantage of this method is that the user verifies the authenticity of the trusted agent before using the keys generated by it. The Leighton-Micali scheme is not vulnerable to the present day attacks like fabrication, modification or denial of service etc. The Leighton-Micali protocol can be employed in real-time systems like smart cards. In addition to the security properties and the simplicity of the protocol, our experiments show that in …

This project in lieu of thesis identifies successful methods of fundraising utilized by a sampling of three secondary theater arts programs from North Texas. Programs were evaluated on their ability to fund their programs and provide a quality arts education for their students. Guidelines for fundraising were developed that allow secondary theater programs to flourish without placing an additional burden on already overextended tax system. Findings were framed in a Marxist socio-economic context, seeking to find some relation between supply-side economics and the failure of certain communities to offer quality arts programs. Marxist philosophy, emphasizing the values of community and shared wealth, served to frame findings in the context of arts programs serving and enhancing their own communities.

The registers of the singing voice, as commonly understood by singers, refer to the different vocal qualities induced by adjustments at the level of the larynx and of the vocal tract. This explains why register unification can be approached either one or a combination of the following procedures: (1) resonance alignment through vowel modification, (2) register alignment through intensity exercises. The wide-spread acceptance of vowel modification has made singers reluctant in exploring other avenues of register development. If registers are laryngeally derived, there should be another way of register unification, which directly addresses the coordination of the laryngeal muscles. In support of this argument, this thesis investigates the teaching practices of a group of twentieth-century American voice teachers, who rely on intensity manipulation as the primary means for enhancing the register adjustments. Intensity exercises such as the messa di voce has long been practiced in historical pedagogy, but it is not until now that voice science confirmed its significance in register coordination.

I have used computer simulations to investigate the behavior of polymeric materials at the molecular level. The simulations were performed using the molecular dynamics method with Lennard-Jones potentials defining the interactions between particles in the system. Significant effort was put into the creation of realistic materials on the computer. For this purpose, an algorithm was developed based on the step-wise polymerization process. The resulting computer-generated materials (CGMs) exhibit several features of real materials, such as molecular weight distribution and presence of chain entanglements. The effect of the addition of a liquid crystalline (LC) phase to the flexible matrix was also studied. The concentration and distribution of the second phase (2P) were found to influence the mechanical and tribological properties of the CGMs. The size of the 2P agglomerates was found to have negligible influence on the properties within the studied range. Moreover, although the 2P reinforcement increases the modulus, it favors crack formation and propagation. Regions of high LC concentration exhibit high probability of becoming part of the crack propagation path. Simulations of the tensile deformation under a uniaxial force have shown that the molecular deformation mechanisms developing in the material depend on several variables, such as the magnitude of …

Composer William Bolcom (1938-) has shown a remarkable capacity for incorporating disparate materials and combining them to create original compositions, while often using traditional genres and forms. This style has earned Bolcom the reputation as a leading composer of American postmodernism. This study provides a brief sketch of Bolcom's development as a postmodern composer, his repertoire for violoncello and piano, and it examines his compositional style as applied in his Sonata for Violoncello and Piano (1989). In the Sonata Bolcom applies a wide variety of musical vocabulary from serious and popular traditions. He juxtaposes contrasting ideas to create and resolve rhythmic, melodic and harmonic tensions and amalgamates concepts of three centuries of music history into one new integral work. All these disparate elements with classical, romantic, impressionist, expressionist, modernist and popular connotations are molded together to form a serious piece of musi c with a sense of humor. The three contrasting movements of the Sonata share many common rhythmic, melodic and harmonic traits. The movements form a congruent work of Classical and Romantic spirit, often reminiscent of Brahms' music, despite the mixed use of traditional, popular, and modernist musical languages.

Aaron Copland has been in the forefront of the American musical scene since the 1920s. He has been called an "American composer" for his ability to formulate the essence of American folk music into a wide variety of mediums. The variety and scope of his compositions encompass a diverse array of styles and techniques. From the jazz influenced works that dominated his early period to the works for Hollywood films, from the chamber music that was directly influenced by his Jewish background to the partial acceptance of serial technique, Copland has managed to delve equally into all these styles. Yet, one could arguably rank his works for the stage as his most popular and generally most successful compositions of his career. The extent to which the American public has accepted these works as being "folk" is a case for the genius and adaptability of Copland's talent. Although works like Appalachian Spring, Rodeo, and Lincoln Portrait command the attention of the general public, of whom Aaron Copland was constantly aware, there are works for the piano that deserve and demand close study by pianists. One such work is the Piano Variations. Written in 1930, it has been acknowledged as a twentieth …

Gottlob Harrer (1703-1755) composed at least twenty-seven sinfonias for his patron Count Heinrich von Bruhl in Dresden from 1731-1747, placing them among the earliest concert symphonies written. Harrer's mostly autograph sinfonia manuscripts are significant documents that provide us with a more thorough understanding of musical activities in and around Dresden. Several of the works indicate topical references, including dance, march, and hunt allusions, that comment on the Dresden social occasions for which Harrer composed these works. Harrer mixes topical references with other gestures in several of his sinfonias to create what I believe is an unrecognized affective language functioning in instrumental works of the time. An examination of the topical allusions in Harrer's works solidifies their connection to the social milieu for which he wrote them, and therefore better defines the genre of the concert sinfonia of the time. The first part of this study of Harrer's sinfonias addresses evidence about the composer, his patron, Dresden society, and the circumstances surrounding the first performances of several works, musical evidence of the composer's stylistic and formal approach to the genre, and the rhetorical meaning of topical gestures in the scores in ways not yet explored. In this dissertation, I demonstrate that …

Due to demographic shifts and efforts to recruit culturally diverse professionals, it is plausible that more Caucasians will encounter ethnic minority counselors in the future. Yet, the majority of multicultural literature has only emphasized Caucasian counselors' multicultural counseling competence. Research has rarely discussed how ethic minority counselors influence the perceptions of Caucasian clients. The research purpose was to explore how acculturation and gender of Asian and Caucasian counselors influence Caucasians' perceptions of the counselors and counseling services. With an analog research design, 562 Caucasian college students read 1 of 8 randomly assigned counselor descriptions, which were varied by counselor characteristics, and reported their perceptions on dependent measures: Counselor Rating Form - Short Version (CRF-S), Working Alliance Inventory - Short (WAI-S) and 4 Willingness items. With the Attitudes Toward Seeking Professional Psychological Help - Shortened Form as a covariate, 15 hypotheses were expected that Caucasians would prefer high-acculturated, same sex, and same ethnic counselors tested by simple contrast, while an exploratory question, investigating main and interaction effects among independent variables (counselor ethnicity, acculturation and gender, and participant gender) on dependent measures, was examined by MANCOVA and ANCOVA. Although only 2 of 15 hypotheses showed significance, the exploratory investigation revealed: Caucasian participants …

Many women reporting PMS symptoms state their symptoms affect their mood, social, and family functioning. This study attempted to provide clinicians with information to assist in psychotherapeutic intervention, by determining the effect PMS has on marital satisfaction. Nineteen female subjects reporting PMS symptoms and their partners completed the study. The Marital Satisfaction Inventory - Revised (MSI-R) and the Moos Menstrual Distress Questionnaire-Form T (MDQ-form T) were used to determine if the nineteen couples reported marital distress as a result of the women's cyclical premenstrual symptoms. The results of the study suggested that the women and their partners, report high levels of marital distress that is not reflective of the cyclical nature of the PMS symptomatology. Scores on the MSI-R for the subjects and their partners indicated the couples perceived level of distress in the t-50 to t-70 range on scales 3-8 is consistent throughout the menstrual cycle. The couples reported higher levels of marital distress than would be the expected norm, suggesting that PMS may be a contributing factor to the level of distress they reported experiencing. This study did not include a control group, which would have provided a norm for couples who do not report PMS by which …

More so than any other science in the past several decades, Biology has seen an explosion of new information and monumental discoveries that have had a profound impact on much more than the science itself. Much of this has occurred at the molecular level. Many of these modern concepts, ideas, and technologies, as well as their historical context, can be easily understood and appreciated at the high school level. Moreover, it is argued here that the integration of this is critical for making biology relevant as a modern science. A contemporary high school biology curriculum should adequately reflect this newly acquired knowledge and how it has already has already begun to revolutionize medicine, agriculture, and the study of biology itself. This curriculum provides teachers with a detailed framework for integrating molecular biology into a high school biology curriculum. It is not intended to represent the curriculum for an entire academic year, but should be considered a significant component. In addition to examining key concepts and discoveries, it examines modern molecular techniques, their applications, and their relevance to science and beyond. It also provides several recommended labs and helpful protocols.
