The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition
Access:
Use of this item is restricted to the UNT Community
The dissertation argues that the development of the British abolition movement was based on the abolitionists' perception that their actions were kairotic; they attempted to shape their own kairos by taking temporal events and reinterpreting them to construct a kairotic process that led to a perceived fulfillment: abolition. Thus, the dissertation examines the rhetorical strategies used by white abolitionists to construct an abolitionist kairos that was designed to produce salvation for white Britons more than it was to help free blacks. The dissertation especially examines the three major texts produced by black persons living in England during the late eighteenth centuryIgnatius Sancho's Letters of the Late Ignatius Sancho (1782), Ottobauh Cugoano's Thoughts and Sentiments on the Evil of Slavery (1787), and Olaudah Equiano's The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African (1789)to illustrate how black rhetoric was appropriated by whites to fulfill their own kairotic desires. By examining the rhetorical strategies employed in both white and black rhetorics, the dissertation illustrates how the abolitionists thought the movement was shaped by, and how they were shaping the movement through, kairotic time. While the dissertation contends that the abolition movement was rhetorically designed to provide redemption, …

Memento mori: Concert for Violoncello and Orchestra
Access:
Use of this item is restricted to the UNT Community
Death, as a subject, has been treated extensively throughout history, both in literature as well as in music. The focus of Memento mori is to portray the inevitability of death through music. The first part of the document is an essay exploring the topic of death, its inevitability, unpredictability and the fragility of life. This section also includes a number of examples of composer's whose works have influenced the composition of the piece. The title of the work is meant to reflect that death catches up with all of us and that humans no matter how invincible they feel at certain stages of life will, eventually, succumb to death. The second part of the document is the notated orchestral score. The work is for full orchestra and solo violoncello. It is in three acts that loosely resemble three stages of life; Youth followed by life in adulthood and finally death. The work is not programmatic and the piece's formal structure varies from a traditional concerto, for although comprised of three distinct acts, there are no pauses between them. The entire work is meant to be dark and morbid and the specter of death looms throughout the piece.

The relationship between training in learning style adaptation and successful completion of entry-level community college classes.
Access:
Use of this item is restricted to the UNT Community
The purpose of this study was to determine if there was a relationship between training in learning style adaptation and successful completion of community college courses. The rationale for conducting this study was based on the need for students to learn how to adapt their learning style in order to more effectively learn in any situation. It is also important that community colleges implement strategies that assist in student retention. The learning styles of entry-level community college students were measured using Kolb's Learning Style Inventory Version 3. Students enrolled in entry-level college courses at a small North Texas community college were studied. The Chi-square Test of Independence with a 2 x 2 design was employed. Findings indicated that there was no statistically significant difference in the relationship between students receiving training in learning styles adaptation and successful completion of entry-level college courses, and that students who attended a learning styles training session and those who did not attend a learning styles training session had an equal chance of succeeding in entry-level community college courses. Findings also indicated that students with Accommodating and Assimilating learning styles are less likely to successfully complete an entry-level college course than are students with Diverging …

The Destruction of a Society: A Qualitative Examination of the Use of Rape as a Military Tool
Access:
Use of this item is restricted to the UNT Community
This thesis explores the conditions under which mass rapes are more likely to be incorporated into the strategy of military or paramilitary groups during periods of conflict. I examine three societies, Rwanda , the former Yugoslavia , and Cambodia in a comparative analysis. To determine what characteristics make societies more likely to engage in rape as a military tool, I look at the status of women in the society, the religious cultures, the degree of female integration into the military institutions, the cause of the conflicts, the history of the conflict, and finally, the status of minority ethnic groups in each of these societies.

Past tense marking in Chinese-English interlanguage.
Access:
Use of this item is restricted to the UNT Community
This data study concentrates on the past tense marking in the interlanguage (IL) of Chinese speakers of English. Following the assumptions of Hawkins & Lizska, (2003), it is assumed that unlike native speakers of English, Chinese speakers of English have a higher level of optionality within the past tense marking of their grammars. It is claimed that the primary reason for this occurrence is the lack of the functional feature T(ense) [+/-past] in Mandarin Chinese. If a particular functional feature is missing in a learner's L1 grammar, it is thought that it will be absent in one's L2 grammar as well. Three advanced Chinese speakers of English were tested on the past tense marking in their IL production. Both spontaneous oral and reading speech were used for this data analysis.

The Effects of Color Concentrate in Polyolefins.
Access:
Use of this item is restricted to the UNT Community
Throughout history consumer products were generally manufactured from wood and metal. They either had to hold their natural color or become subject to painting. When plastics entered the industry, it was recognized for its ease of shaping, re-usability, physical properties and its low cost. One of plastics' greatest benefits is its ability to hold a given color from within allowing it to avoid use of paint. This paper will give a brief overview on the effects of pigments when incorporated in a polyolefin. It will provide a classification of the main types of pigments and how each effect the properties of the product through: crystallization, weatherability, opacity, coloristic values and of course viscosity.

This study assesses practices of college students (N=913) toward alternative medicine, relationships of students' health locus of control with practices of alternative medicine, and relationships of students' attitudes toward alternative medicine and health locus of control. A principal components factor analysis established construct validity of the author-designed Attitude Toward Alternative Medicine Scale, extracting three factors: Holistic Attitude/Control, Safety, and Satisfaction. Holistic Attitude/Control predicted use of alternative medicine (Wald =61.9, p < .01). A principal components factor analysis established construct validity of the Multidimensional Health Locus of Control Scale, extracting three factors: Internal Health Locus of Control, External-Chance, and External-Powerful Others. Internal Health Locus of Control significantly correlated with Holistic Attitude/Control (r = .35, p =.01).

Access:
Use of this item is restricted to the UNT Community
The purpose of this study was to analyze the impact of alternative school intervention on subsequent student performance. The literature review examined the history and development of alternative schools, the legislation pertaining to alternative schools, and related studies. The population consisted of students placed in the discipline alternative education program (DAEP) of an alternative school located in a large suburban school district in north Texas. Students placed in DAEP in the spring semester of 2001 in grades 7, 8, 9, and 10 were included in the sample. Data on student success was gathered for the one semester prior to placement (pre-intervention) and for the two semesters after placement (post-intervention). Student success was measured in terms of course grade averages and attendance. The student sample was divided into the following subgroups: grade level, sex, ethnicity, and qualification for the school meal program. The students' grade averages were compared within the subgroups utilizing a one-way analysis of variance (ANOVA). Tukey's post hoc comparison was utilized on the groups when ANOVA was found to be significant. The students' attendance was analyzed by comparing the proportion of days attended in each of the three semesters included in the study. A normal test of two …

A Quality of Service Aware Protocol for Power Conservation in Wireless Ad Hoc and Mobile Networks
Access:
Use of this item is restricted to the UNT Community
Power consumption is an important issue for mobile computers since they rely on the short life of batteries. Conservation techniques are commonly used in hardware design of such systems but network interface is a significant consumer of power, which needs considerable research to be devoted towards designing a low-power design network protocol stack. Due to the dynamic nature of wireless networks, adaptations are necessary to achieve energy efficiency and a reasonable quality of service. This paper presents the application of energy-efficient techniques to each layer in the network protocol stack and a feedback is provided depending on the performance of this new design. And also a comparison of two existing MAC protocols is done showing a better suitability of E2MAC for higher power conservation. Multimedia applications can achieve an optimal performance if they are aware of the characteristics of the wireless link. Relying on the underlying operating system software and communication protocols to hide the anomalies of wireless channel needs efficient energy consumption methodology and fair quality of service like E2MAC. This report also focuses on some of the various concerns of energy efficiency in wireless communication and also looks into the definition of seven layers as defined by International …

Traqueros: Mexican Railroad Workers in the United States, 1870 to 1930
Access:
Use of this item is restricted to the UNT Community
Perhaps no other industrial technology changed the course of Mexican history in the United States—and Mexico—than did the coming of the railroads. Tens of thousands of Mexicans worked for the railroads in the United States, especially in the Southwest and Midwest. Extensive Mexican American settlements appeared throughout the lower and upper Midwest as the result of the railroad. Only agricultural work surpassed railroad work in terms of employment of Mexicans. In Traqueros, Jeffrey Marcos Garcílazo mined numerous archives and other sources to provide the first and only comprehensive history of Mexican railroad workers across the United States, with particular attention to the Midwest. He first explores the origins and process of Mexican labor recruitment and immigration and then describes the areas of work performed. He reconstructs the workers’ daily lives and explores not only what the workers did on the job but also what they did at home and how they accommodated and/or resisted Americanization. Boxcar communities, strike organizations, and “traquero culture” finally receive historical acknowledgment. Integral to his study is the importance of family settlement in shaping working class communities and consciousness throughout the Midwest.

Equity of access: Exploring Internet connectivity within Oklahoma public schools.
Access:
Use of this item is restricted to the UNT Community
The purpose of this study was to ascertain if conditions or combinations of conditions existed within Oklahoma public schools that created inequities in the availability of classroom Internet connections. A stratified random sample of the 471 school districts was used to identify 300 specific schools for the purpose of data analysis. Data was gathered utilizing a database provided by the Oklahoma State Department of Education and a researcher developed questionnaire. The database provided data relating to four independent variables (region, district size, school type, and school size,). The dependent variable, percentage of classrooms connected to the Internet, was obtained by the researcher designed questionnaire. The state database also provided percentage information relating to students who qualify as minorities and qualify for free or reduced lunches. The data was tested using a series of ANOVAs and a Pearson product-moment correlation coefficient. The findings of the study are as follows: (a) The analysis of variance showed that none of the independent variables had a significant effect upon the percentage of classrooms connected to the Internet; (b) The Pearson product-moment correlation coefficient revealed little or no correlation between the percentage of disadvantaged or minority students and the percentage of classroom Internet connections.

Hamiltonian cycles in subset and subspace graphs.
Access:
Use of this item is restricted to the UNT Community
In this dissertation we study the Hamiltonicity and the uniform-Hamiltonicity of subset graphs, subspace graphs, and their associated bipartite graphs. In 1995 paper "The Subset-Subspace Analogy," Kung states the subspace version of a conjecture. The study of this problem led to a more general class of graphs. Inspired by Clark and Ismail's work in the 1996 paper "Binomial and Q-Binomial Coefficient Inequalities Related to the Hamiltonicity of the Kneser Graphs and their Q-Analogues," we defined subset graphs, subspace graphs, and their associated bipartite graphs. The main emphasis of this dissertation is to describe those graphs and study their Hamiltonicity. The results on subset graphs are presented in Chapter 3, on subset bipartite graphs in Chapter 4, and on subspace graphs and subspace bipartite graphs in Chapter 5. We conclude the dissertation by suggesting some generalizations of our results concerning the panciclicity of the graphs.

Use of this item is restricted to the UNT Community
The purposes of this study were to examine the prevalence of current substance use and early risk indicators for substance abuse and dependence, and to investigate the relationships among religiousness, current substance use, and early risk indicators among nursing students at seven Seventh-day Adventist colleges. Data for this descriptive study were collected through Efinger's Alcohol Risk Survey (EARS) (Efinger, 1984), the CAGE Questionnaire ( Ewing , 1984), and the Intrinsic/Extrinsic-Revised Scale (Gorsuch & McPherson, 1989). Participants were 241 nursing students enrolled in their first year of nursing courses at seven colleges and universities located across the United States . Findings indicated that 42% of students scored higher than the EARS mean; 24% reported current substance use; and 15% scored in the probable abuse/dependence category of CAGE. Students who reported current substance use and those scoring in the probable substance abuse/dependence category were significantly more likely to score above the EARS median. Intrinsic religiousness demonstrated a significant inverse relationship with current substance use. Significantly lower rates of current substance use were associated with higher rates of attendance at religious services. Respondents who indicated that their religion prohibited alcohol consumption reported significantly lower rates of current substance use than those who answered …

Implementation of Back Up Host in TCP/IP
Access:
Use of this item is restricted to the UNT Community
This problem in lieu thesis is considering a TCP client H1 making a connection to distant server S and is downloading a file. In the midst of the downloading, if H1 crashes, the TCP connection from H1 to S is lost. In the future, if H1 restarts, the TCP connection from H1 to S will be reestablished and the file will be downloaded again. This cannot happen until host H1 restarts. Now consider a situation where there is a standby host H2 for the host H1. H1 and H2 monitor the health of each other by heartbeat messages (like SCTP). If H2 detects the failure of H1, then H2 takes over. This implies that all resources assigned to H1 are now reassigned or taken over by H2. The host H1 and H2 transmit data between each other when any one of it crashed. Throughout the data transmission process, heart beat chunk is exchanged between the hosts when one of the host crashes. In particular, the IP addresses that were originally assigned to H1 are assigned to H2. In this scenario, movement of the TCP connection between H1 and S to a connection between H2 and S without disrupting the TCP …

Perceptions of Postpartum Depression among Adolescent Mothers and the Social Construction of Related Stigma
Access:
Use of this item is restricted to the UNT Community
Six serial focus groups were used to explore the perceptions of postpartum depression among nine adolescent mothers. The discussions were tape recorded, transcribed and analyzed using symbolic interaction theory, specifically Goffman's concept of stigma. Participants identified major stigma themes in relation to postpartum depression, teenage pregnancy and motherhood, all of which were portrayed negatively in the media. Several key causes of adolescent postpartum depression were also found including self esteem relating to poor body image and social support. The findings indicate a much needed change in the way adolescent mothers are identified and treated for postpartum depression. Additionally, the importance of social support in preventing and treating adolescent postpartum depression is highlighted and programs addressing such concerns must be implemented.

Deep Learning Approach for Sensing Cognitive Radio Channel Status
Access:
Use of this item is restricted to the UNT Community
Cognitive Radio (CR) technology creates the opportunity for unlicensed users to make use of the spectral band provided it does not interfere with any licensed user. It is a prominent tool with spectrum sensing functionality to identify idle channels and let the unlicensed users avail them. Thus, the CR technology provides the consumers access to a very large spectrum, quality spectral utilization, and energy efficiency due to spectral load balancing. However, the full potential of the CR technology can be realized only with CRs equipped with accurate mechanisms to predict/sense the spectral holes and vacant spectral bands without any prior knowledge about the characteristics of traffic in a real-time environment. Multi-layered perception (MLP), the popular neural network trained with the back-propagation (BP) learning algorithm, is a keen tool for classification of the spectral bands into "busy" or "idle" states without any a priori knowledge about the user system features. In this dissertation, we proposed the use of an evolutionary algorithm, Bacterial Foraging Optimization Algorithm (BFOA), for the training of the MLP NN. We have compared the performance of the proposed system with the traditional algorithm and with the Hybrid GA-PSO method. With the results of a simulation experiment that this …

Cognitive and Perceptual-Motor Indicators of Lateralized vs. Diffuse Brain Damage in Adults.
Access:
Use of this item is restricted to the UNT Community
Among the goals of the neuropsychological assessment are to detect the presence of brain damage, localize which areas of the brain may be dysfunctional and describe subsequent functional impairments. The sensitivity of neuropsychological instruments in carrying out these functions is a question of some debate. The purpose of this study is to determine the utility of lateralizing indicators from the WAIS-III, McCarron Assessment of Neuromuscular Development (MAND) and Haptic Visual Discrimination Test (HVDT), from the McCarron-Dial System Neuropsychological Assessment Battery (MDS), in ascertaining the presence or absence of brain damage as well as location of lesion. The classification accuracies of using performance level indicators from these tests and lateralizing indicators, alone and together, were compared.

Neuromotor and Neurocognitive Functioning in the Prediction of Cognition, Behavior Problems, and Symptoms at Two-year Follow-up in Youth with Schizotypal Personality Disorder
Access:
Use of this item is restricted to the UNT Community
Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits, neuromotor disturbances, and behavior problems similar to individuals with schizophrenia, and thus SPD is thought to represent one point on the continuum of schizophrenia spectrum disorders (SSDs). Deficits in behavior, cognition, and motor functioning have been implicated as childhood precursors of SSDs and appear to also vary as a function of gender and family history of psychopathology. As such, studies of youth may help in further identification of individuals at risk for SSDs. The current study examined the prospective associations between problem behaviors, neuromotor and neurocognitive functioning, as well as SSD symptoms, at baseline and 2-year follow-up in youth meeting criteria for SPD, other personality disorders, or healthy controls. The neuromotor and neurocognitive measures were able to significantly predict SSD symptoms and behavior problems above and beyond baseline predictors. Overall, the findings provide further support for the role of subcortical motor centers operating together with prefrontal cortical areas in the regulation of higher-order cognitive functioning and in producing the psychiatric features of SSDs. Significant correlations between gender, family history of schizophrenia, and history of head injury with symptoms, behavior, cognition, and motor functioning were also found and highlight …

Use of this item is restricted to the UNT Community
With the growing popularity of e-commerce applications that use software agents, the protection of mobile agent data has become imperative. To that end, the performance of four methods that protect the data integrity of mobile agents is evaluated. The methods investigated include existing approaches known as the Partial Result Authentication Codes, Hash Chaining, and Set Authentication Code methods, and a technique of our own design, called the Modified Set Authentication Code method, which addresses the limitations of the Set Authentication Code method. The experiments were run using the DADS agent system (developed at the Network Research Laboratory at UNT), for which a Data Integrity Module was designed. The experimental results show that our Modified Set Authentication Code technique performed comparably to the Set Authentication Code method.
