The Role of Intelligent Mobile Agents in Network Management and Routing
In this research, the application of intelligent mobile agents to the management of distributed network environments is investigated. Intelligent mobile agents are programs which can move about network systems in a deterministic manner in carrying their execution state. These agents can be considered an application of distributed artificial intelligence where the (usually small) agent code is moved to the data and executed locally. The mobile agent paradigm offers potential advantages over many conventional mechanisms which move (often large) data to the code, thereby wasting available network bandwidth. The performance of agents in network routing and knowledge acquisition has been investigated and simulated. A working mobile agent system has also been designed and implemented in JDK 1.2.

Sarah T. Hughes: Her Influence in Texas Politics
Access:
Use of this item is restricted to the UNT Community
Conservative males traditionally dominated Texas politics. In 1930, however, Sarah T. Hughes, a liberal woman from Maryland, began a spectacular career in state politics despite obstacles because of her gender and progressive ideas. First elected to the Texas Legislature in 1930, she remained active in politics for the next fifty years. Hard work, intelligence, and ability allowed her to form solid friendships with Texas's most powerful politicians. She became the first woman in Texas to hold a district judgeship, the first woman from Texas appointed to the federal bench, and the only woman to swear in a U.S. president. Hughes profoundly influenced state politics, challenging the long-standing conservative male domination. She helped to create a more diverse political field that today encompasses different ideologies and both genders.

Singing for Blaine and for Logan! Republican Songs as Campaign Literature in the 1884 Presidential Race
During the presidential contest of 1884, Republicans used singing as a campaign tactic at rallies, meetings, and parades. Their songs may be divided into several categories, such as rally songs, songs of praise for the party and its candidate, "bloody shirt" songs, mudslinging songs, and issue-based songs. Songs provide a perspective on the overall tenor of the campaign, while a lack of songs on certain topics, such as temperance, reflects the party's reluctance to alienate voters by taking a strong stand on controversial issues. Although the campaign has often been called one of the dirtiest in American history, this negativity is not reflected in the majority of the songs.

Single Family Housing Construction Trends in the Denton Independent School District and Their Implications for School Enrollment
The purpose of this study is to examine housing construction trends in the Denton Independent School District area for the next 5 years estimating impacts on the resulting school district enrollments. Combining enrollment data obtained from the DISD and housing data from the Denton County Appraisal District, it is possible to calculate enrollment multipliers for elementary, middle, and high school students based on predefined categories of single family home values. The study suggests that enrollment multipliers currently used by the DISD over estimate the number of students coming from new single family residences, especially at the elementary school level. Using data from real estate agents, builders, developers, and permitting boards, a map is created showing areas of the DISD that will likely see the largest gains in school-age children during the next 2 to 5 years.

Synthesis and characterization of molecules for electron transfer research.
Dimethoxynaphthalene (donor) and quinone (acceptor) have been chosen as a suitable redox pair and are bonded to either permethylated silane chains or corresponding permethylated alkyl chains to form Acceptor-(Bridge)-Donor molecules. The idea that the s-delocalization phenomenon of silane chains may greatly facilitate ET reactions will be tested. The starting material for the donor precursor, 4-(1,4-dimethoxynaphthyl)bromocyclohexane, was 1,4-naphthoquinone. After methylation and bromination, the Grignard reagent of the resulting bromide was reacted with cyclohexanedione, mono ethylene ketal. The resulting alcohol was changed to the donor precursor through the following functional group transformation steps: dehydration, hydrogenation, deketalization and bromination. 1,4-Dibenzyloxybromobenzene, the precursor for the acceptor, was synthesized from 1,4-hydroquinone through bromination and benzylation. The connection of the two precursors and either permethylated silane chains or permethylated alkyl chains will give the final target molecules for ET research. Progress on this is included.

Teachers' and Students' Perceptions of the Impact of Content Literacy Strategy Instruction on Teaching and Learning
Reading researchers agree that content literacy strategies are beneficial in helping students learn. However, teachers remain resistant to teaching the strategies. Additionally, many students, even at the college level, lack the learning strategies necessary to experience academic success. This study sought to gain a deeper understanding of the complexities of content literacy strategy instruction. The research questions that guided the study addressed the benefits, obstacles, and support and experiences needed to sustain the use of the strategies over time. Multiple data sources were used to investigate teachers' and students' perceptions of the research questions. The main benefit found was increased student understanding and learning of content; additional benefits included increased instructional repertoire, increased student engagement in class, and improved learner independence. Most of the obstacles documented in the literature were supported in the study; however, the obstacle of time was noted most frequently. Teacher confidence was observed by the researcher as an obstacle. The majority of participants indicated they would continue using the strategies learned during the study in the future. Students noted the support needed to sustain content literacy strategy use depended on teachers providing direct instruction, practice using the strategies, and personal success with the strategies. Teachers also …

Teachers' Use of Children's Literature, Mathematics Manipulatives, and Scaffolding to Improve Preschool Mathematics Achievement: Does It Work?
The primary purpose of this study was to determine if the implementation of an intervention involving teachers' use of children's literature, related storybook manipulatives, and a scaffolding (LMS) approach to learning would improve preschool children's mathematics test scores. Additionally, the LMS approach was examined to determine whether teachers' perceptions of their effectiveness in mathematics instruction changed from the beginning to the end of the study. The subjects of the study included 60 preschool-aged children and six teachers from two child care centers. The preschool teachers participated in either a control or experimental condition (the LMS approach) in their daily mathematics instruction with their preschool children. The researcher tested the children using the Test of Early Mathematics Ability and an abbreviated version of the Stanford-Binet Intelligence Scale. The study was based on two main research questions. The first question asked if there was a difference in the Test of Early Mathematics Ability total posttest scores between children in the literature-manipulatives-scaffolding intervention group and children in the control group after assuring equivalency of the two groups. The second question addressed if preschool teachers believed they were more effective in their mathematics instruction after implementing the LMS approach with young children. The answer …

The Thematic Apperception Test: The relationship between scored fanasy aggression and aggressive behavior
This study attempted to determine the relationship between fantasy aggression and behavioral aggression, and whether fantasy aggression measured by the Thematic Apperception Test is related to behavioral aggression. Participant TAT protocols from psychology clinic files were scored for fantasy aggression, and these scores were correlated with self-reported presence or absence of behavioral aggression. The scoring system used was a blend of popular aggression scales used in the 1960s and newer theory. Other variables that were examined were story length and gender in relation to the measured amount of fantasy and behavioral aggression.

Themes of Exodus and Revolution in Ellison's Invisible Man, Morrison's Beloved, and Doctorow's Ragtime
In my dissertation I examine the steps in and performance of revolution through the writings of three Postmodern authors, Ralph Ellison, Toni Morrison, and E. L. Doctorow, in light of the model of the biblical Exodus journey and the revolution which precipitated that movement. I suggest that the revolution which began with the Israelites' bondage in Egypt has provided the foundation for American literature. I show that Invisible Man, Beloved, and Ragtime not only employ the motif of the Exodus journey; they also perpetuate the silent revolution begun by the Israelites while held captive in Egypt. This dissertation consists of six chapters. Chapter One provides the introduction to the project. Chapter Two provides the model for this study by defining the characteristics of the Exodus journey, Moses as the leader of the Israelites, and the pattern of revolution established by Michael Walzer in Exodus and Revolution. In Chapters Three, Four, and Five, I apply the model established in Chapter Two to the individual texts. In Chapter Six, I draw three conclusions which arise from my study. My first conclusion is that the master story of the Exodus journey and the Israelites' liberation from Egypt informs all Western literaturewhether the literature …

"This Beautiful Evil": The Connection between Women, the Natural World, Female Sexuality, and Evil in Western Tradition
Female archetypes reflect a social construction of reality, expressing expected modes of behavior, beliefs, and assumptions about women and are reinforced by repetition of common patterns and themes. Often female archetypes take on the physical characteristics of animals, commune with nature, engage in sexual promiscuity, and possess special powers to bewitch and control men into doing their bidding. Four prevalent archetypes include: the Predatory Woman, who with her bestial nature becomes the hunter of men; the Sacrificial Woman, who dutifully negates herself for the sake of men; the Bad Mother, who is cold, unnatural, and challenges men; and les enfants terrible seductive girl-women who at once tempt and torment men. This research traces the development and evolution of female archetypes and explores how images of women, nature, sexuality, and evil are structured within a cultural framework of Western tradition: myths and folktales, religious, philosophical, and scientific works, and film.

Three Voices for voices, woodwind, percussion, and string instruments
Composed for soprano, tenor, and baritone voices, woodwind, percussion, and string instruments, Three Voices is a polyglotic work that includes German, Chinese, and Spanish texts. The texts are chosen from Brecht Bertolt's Das Schiff, Po Chu I's Lang T'ao Sha, and Frederico Garcia Lorcá's Mar. Significant features of the piece are 1) application of Chinese operatic singing methods to vocal material in the sections that use Chinese text, 2) use of western instruments to emulate the sound of certain Chinese instruments, and 3) employment of Sprechstimme and dramatically inflected speech to create theatrical effects and highlight the sections that use German and Spanish texts.

Thresholds in avian communities at multiple scales: Relationships between birds, forests, habitats, and landscapes in the Ray Roberts greenbelt, Denton
Environmental management agencies make efforts to reduce pollution loading in streams and rivers by promoting vegetated buffer zones between human activity and water. Most of these efforts do not mesh water quality-based buffer zone width requirements with conservation and wildlife values, specifically, the use of these riparian forest corridors for wildlife dispersal between habitats in highly fragmented landscapes. Forest interior birds are of the most concern to management in riparian forests due to their population declines across much of their breeding range. This dissertation investigates the role that landscape-level and habitat-level factors play on the presence of breeding birds in riparian forests, particularly the landscape and habitat factors that are influenced by human-caused fragmentation. This study describes research at the Ray Roberts Greenbelt, Denton, Texas, that explores the relationships between the landscape and forest habitats of the Greenbelt with its breeding bird community. The major findings of this study are that bird communities in the corridor forests are associated with a greater array of factors than are bird communities in patches, suggesting that the birds of patch forests are somewhat insulated from landscape-scale effects. Also, habitat values can be maintained in corridors, but there does not seem to be a …

Training family therapists to work with families with young children: Current practices in accredited family therapy programs and recommendations for the future
This study examined how current family counseling/therapy programs train students to work with families with young children and made recommendations for training in this area based on recommendations of child and family therapy experts and the research and clinical literature. These recommendations explored what knowledge and skills all students should acquire versus students who want to specialize with this population. Changes to accreditation standards were also proposed as well as a description of resources to support changes in program curricula. Current training was measured by examining curricula from master's level marriage and family counseling/therapy programs accredited by the Commission on Accreditation for Marriage and Family Therapy Education (COAMFTE) and the Council for Accreditation of Counseling and Related Education Programs (CACREP) and master's level social work programs with a family-related concentration accredited by the Council on Social Work Education Commission on Accreditation (CSWE), the accreditation standards from these three organizations, course syllabi from the COAMFTE and CACREP programs, and surveys of COAMFTE and CACREP program directors (60% response rate). Recommendations for training were obtained through a qualitative analysis of quotations from the literature concerning training and through interviews of child and family therapy experts (65% response rate). The results revealed the …

Unexpected Unexpected Utilities: A Comparative Case-Study Analysis of Women and Revolutions
Women have been part of modern revolutions since the American Revolution against Great Britain. Most descriptions and analyses of revolution relegate women to a supporting role, or make no mention of women's involvement at all. This work differs from prior efforts in that it will explore one possible explanation for the successes of three revolutions based upon the levels of women's support for those revolutions. An analysis of the three cases (Ireland, Russia, and Nicaragua) suggests a series of hypotheses about women's participation in revolution and its importance to revolutions' success.

Use of Automated Sampler to Characterize Urban Stormwater Runoff in Pecan Creek
The purpose of this study was to use the Global Water Stormwater Sampler SS201 to characterize the urban runoff in Pecan Creek. Location of the samplers was influenced by land use and ease of installation. Determination of the constituents for analysis was modeled after those used in the NPDES permit for seven cities within the Dallas/Ft.Worth metroplex. Some metals, notably cadmium and arsenic, exceeded the U.S. EPA's MCL's. Statistical analysis revealed first flush samples to be significantly more concentrated than composite samples. Minimum discharge loadings were found to be significantly lower than maximum discharge loadings. Additionally there were significant differences of specific constituents between station locations and storm events.

Work in the calling in Max Weber's Protestant ethic thesis
Access:
Use of this item is restricted to the UNT Community
Objectives. Scholars have debated Max Weber's theory of the relationship between religion and capitalism for almost 100 years. Still, the debate is clouded by confusion over Weber's claims about religious doctrine and over the supporting evidence. The purpose of this study is to clarify Max Weber's claims regarding the concept of the calling and the related "anti-mammon" injunction and concept of "good works" and substantiate with historical evidence the religious doctrine Weber describes. Methods. Comparative analysis of early Protestant Lutheran and Calvinist documents from the sixteenth and seventeenth centuries was used to flesh out a history of ideas to determine whether evidence exists to support Weber's claims related to religious doctrine. Results. Historical analyses revealed that the concept of the calling pre-dated Luther in the Bible. Luther's innovation was not in his use of the word beruf but in his application of the concept of the calling to the common people and his teaching of that idea. The idea of sanctified work was key in both Lutheran and Calvinist documents. There was an increased emphasis on work and encouragement to accumulate wealth in Calvinist documents. Conclusion. Weber's etymological evidence surrounding Martin Luther's use of the word beruf in his German …
