Investigation of Relational and Overt Aggression Among Boys and Girls

Description: Given the paucity of research that has been conducted on aggression in girls (see Keenan, Loeber, & Green, 1999, for a review), it is important to examine different behavioral manifestations of aggression that may be more prevalent among girls than boys, such as relational aggression (see Crick et al., 1999, for a review). Relational aggression consists of behaviors that harm others through damage to their peer relationships or the threat of such damage (e.g., spreading rumors about a peer so that others will reject him/her, social exclusion; Crick & Grotpeter, 1995). Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are a particular subset of youth who are at increased risk for exhibiting aggressive behavior (Henker & Whalen, 1999; Whalen & Henker, 1985). The purpose of the present study was to assess the prevalence of relational aggression among children with attention problems as compared to the general population. Gender differences in relational aggression were also examined. In the current study, participants included 91 3rd-5th grade public school students. Teacher ratings of aggressive behavior and attention problems were obtained. Parents also completed measures to assess attention problems and social-psychological adjustment. Contrary to prediction, results indicated children with attention problems were not more aggressive than children without attention problems, regardless of the type of aggressive behavior assessed (i.e., relational or overt aggression). With respect to gender differences in relational aggression, results indicate the well-known gender effect for relational aggression only applies to Caucasian students in this sample, as a gender effect for relational aggression was not obtained for Hispanic students. Thus, the gender effect for relational aggression should not be considered a robust finding generalizable to all ethnic groups. Finally, relationally aggressive children were reported to be as well-adjusted as their non-relationally aggressive peers, which is not consistent with previous research. Regardless of aggression status, Hispanic …

Building an Intelligent Filtering System Using Idea Indexing

Description: The widely used vector model maintains its popularity because of its simplicity, fast speed, and the appeal of using spatial proximity for semantic proximity. However, this model faces a disadvantage that is associated with the vagueness from keywords overlapping. Efforts have been made to improve the vector model. The research on improving document representation has been focused on four areas, namely, statistical co-occurrence of related items, forming term phrases, grouping of related words, and representing the content of documents. In this thesis, we propose the idea-indexing model to improve document representation for the filtering task in IR. The idea-indexing model matches document terms with the ideas they express and indexes the document with these ideas. This indexing scheme represents the document with its semantics instead of sets of independent terms. We show in this thesis that indexing with ideas leads to better performance.

Paying for the Arts: Fundraising Methods for Secondary Theater Programs

Description: 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.

Stretched Out on Her Grave: Pathological Attitudes Toward Death in British Fiction 1788-1909

Description: Nineteenth-century British fiction is often dismissed as necrophillic or obsessed with death. While the label of necrophilia is an apt description of the fetishistic representations of dead women prevalent at the end of the century, it is too narrow to fit literature produced earlier in the century. This is not to say that abnormal attitudes toward death are only a feature of the late nineteenth century. In fact, pathological attitudes toward death abound in the literature, but the relationship between the deceased and the survivor is not always sexual in nature. Rather, there is a clear shift in attitudes, from the chaste death fantasy, or attraction to the idea of death, prevalent in Gothic works, to the destructive, stagnant mourning visible in mid-century texts, and culminating in the perverse sexualization of dead women at the turn of the century. This literary shift is most likely attributable to the concurrent changes in attitudes toward sex and death. As sex became more acceptable, more public, via the channels of scientific discourse, death became a less acceptable idea. This “denial of death” is a direct reaction to the religious uncertainties brought about by industrialization. As scientists and industrialists uncovered increasing evidence against a literal interpretation of the Bible, more people began to doubt the nature of God and the existence of an afterlife. If there was no God, then there was no heaven, which raised questions about what happened to the soul after death. With the certainty of an afterlife gone, death became mysterious, something to fear, and the passing of loved ones was doubly-mourned as their fate was now uncertain.

A Dynamic and Thermodynamic Approach to Complexity.

Description: The problem of establishing the correct approach to complexity is a very hot and crucial issue to which this dissertation gives some contributions. This dissertation considers two main possibilities, one, advocated by Tsallis and co-workers, setting the foundation of complexity on a generalized, non-extensive , form of thermodynamics, and another, proposed by the UNT Center for Nonlinear Science, on complexity as a new condition that, for physical systems, would be equivalent to a state of matter intermediate between dynamics and thermodynamics. In the first part of this dissertation, the concept of Kolmogorov-Sinai entropy is introduced. The Pesin theorem is generalized in the formalism of Tsallis non-extensive thermodynamics. This generalized form of Pesin theorem is used in the study of two major classes of problems, whose prototypes are given by the Manneville and the logistic map respectively. The results of these studies convince us that the approach to complexity must be made along lines different from those of the non-extensive thermodynamics. We have been convinced that the Lévy walk can be used as a prototype model of complexity, as a condition of balance between order and randomness that yields new phenomena such as aging, and multifractality. We reach the conclusions that these properties must be studied within a dynamic rather than thermodynamic perspective. The second part focuses on the study of the heart beating problem using a dynamic model, the so-called memory beyond memory, based on the Lévy walker model. It is proved that the memory beyond memory effect is more obvious in the healthy heart beating sequence. The concepts of fractal, multifractal, wavelet transformation and wavelet transform maximum modulus (WTMM) method are introduced. Artificial time sequences are generated by the memory beyond memory model to mimic the heart beating sequence. Using WTMM method, the multifratal singular spectrums of the sequences …

Improving Topic Tracking with Domain Chaining

Description: Topic Detection and Tracking (TDT) research has produced some successful statistical tracking systems. While lexical chaining, a non-statistical approach, has also been applied to the task of tracking by Carthy and Stokes for the 2001 TDT evaluation, an efficient tracking system based on this technology has yet to be developed. In thesis we investigate two new techniques which can improve Carthy's original design. First, at the core of our system is a semantic domain chainer. This chainer relies not only on the WordNet database for semantic relationships but also on Magnini's semantic domain database, which is an extension of WordNet. The domain-chaining algorithm is a linear algorithm. Second, to handle proper nouns, we gather all of the ones that occur in a news story together in a chain reserved for proper nouns. In this thesis we also discuss the linguistic limitations of lexical chainers to represent textual meaning.

Interfacial Electrochemistry and Surface Characterization: Hydrogen Terminated Silicon, Electrolessly Deposited Palladium & Platinum on Pyrolyzed Photoresist Films and Electrodeposited Copper on Iridium

Description: Hydrogen terminated silicon surfaces play an important role in the integrated circuit (IC) industry. Ultra-pure water is extensively used for the cleaning and surface preparation of silicon surfaces. This work studies the effects of ultra-pure water on hydrogen passivated silicon surfaces in a short time frame of 120 minutes using fourier transform infrared spectroscopy – attenuated total reflection techniques. Varying conditions of ultra-pure water are used. This includes dissolved oxygen poor media after nitrogen bubbling and equilibration under nitrogen atmosphere, as well as metal contaminated solutions. Both microscopically rough and ideal monohydride terminated surfaces are examined. Hydrogen terminated silicon is also used as the sensing electrode for a potentiometric sensor for ultra-trace amounts of metal contaminants. Previous studies show the use of this potentiometric electrode sensor in hydrofluoric acid solution. This work is able to shows sensor function in ultra-pure water media without the need for further addition of hydrofluoric acid. This is considered a boon for the sensor due to the hazardous nature of hydrofluoric acid. Thin carbon films can be formed by spin coating photoresist onto silicon substrates and pyrolyzing at 1000 degrees C under reducing conditions. This work also shows that the electroless deposition of palladium and platinum may be accomplished in hydrofluoric acid solutions to attain palladium and platinum nanoparticles on a this film carbon surface for use as an electrode. Catalysis of these substrates is studied using hydrogen evolution in acidic media, cyclic voltammetry, and catalysis of formaldehyde. X-ray diffractometry (XRD) is used to ensure that there is little strain on palladium and platinum particles. Iridium is thought to be a prime candidate for investigation as a new generation copper diffusion barrier for the IC industry. Copper electrodeposition on iridium is studied to address the potential of iridium as a copper diffusion barrier. Copper electrodeposition …

The Effects of "Errorless" Training and Testing on the Performances of Typically Developing Children During Acquisition and Retention.

Description: This study examines the effects of two teaching procedures and two testing procedures (“Skip” and “Guess”) on acquisition, retention and generalization of learning. Three typically developing females between the ages of 8 and 11 learned the 24 lower case letters of the Greek alphabet. Half of the letters were taught with the “Skip” procedure and the other half with the “Guess” procedure. The “Skip” procedure produced faster and more efficient learning than the “Guess” procedure. The “Skip” procedure also resulted in better initial retention (4 weeks), but this effect disappeared in subsequent retention tests. The training conditions did not have differential effects on generalization tests across learning channels, except for the Free/Say channel.

The Effects of Workshop Training and Coaching on the Acquisition and Generalization of Teaching Skills

Description: The purpose of this study was threefold: (a) to examine the separate effects of increased accuracy on multiple-choice/rank-order written tests and coaching on the teaching performance of participants; (b) to compare generalization across tasks produced by the workshop and coaching; and (c) to assess maintenance of teaching performance. Following baseline, two adults received a lecture on discrete trial teaching procedures. A written test measured verbal performance on workshop material periodically throughout this phase. During the next phase, each adult then experienced further training via in-situ coaching. A multiple baseline design across tasks was used during the coaching phase. Results of the workshop training package revealed an inverse relationship between the strongest verbal performance and strongest teaching performance skill areas. In addition, only with the introduction of the in-situ coaching package did teacher performance improve significantly across all behaviors. Child responding remained relatively constant throughout the study, regardless of teacher performance. Some generalization of teacher behavior was observed across tasks, but was extremely variable across both workshop and coaching conditions. After the cessation of coaching, teacher performance remained stable across maintenance phases and at a 6-week follow-up.

Teaching Children with Autism Three Different Questions

Description: Children with autism often exhibit deficits in question-asking. This study replicated and extended Williams, Donley, and Keller.s (2000) training package: a modeling and reinforcement procedure to teach the use of 3 different questions about hidden objects. Two boys, aged 13 and 12, with primary diagnoses of autism, participated. A multiple baseline design across questions was used. Both children learned to ask all three questions: .What.s that?. .Can I see (item name)?. and .Can I have (item name)?. Question-asking generalized to novel locations, people, and stimulus materials with minimal additional training. These results support the efficacy of this training package as an efficient way to teach children with autism to ask questions about objects in their environment.

NCAA Division I Athletes Preferences for Coaching Behaviors

Description: The purpose of this study was to determine whether coaching behavior preferences of NCAA Division I athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnare (CBQ; Martin & Barnes, 1999) was administered to 195 NCAA Division I athletes. Gender and sport type were the independent variables and the participant's mean scores for the subscales on the CBQ were the dependent variables. Descriptive statistics revealed that, overall, NCAA Division I athletes prefer positive and instructional behaviors more than non-responses or negative behaviors. A 2 (gender) x 3 (type of sport) MANOVA and follow-up discriminant function analysis indicated that coaching behavior preferences differed as a function of gender and type of sport played. Thus, NCAA Division I coaches should consider both individual and situational characteristics when working with their athletes to achieve the desired outcome.

Early Literacy: An Examination of the Principal Behaviors That Impact Reading Achievement

Description: Literacy is fundamental to formal education, learning, and training for future career related skills. It provides not only the means of acquisition of information and skills during schooling, but it is a vital predictor of a person's general level of education in school as well as successful completion of schooling. Literacy skills serve as the major foundational skill for all school-based learning and without it, chances for academic and occupational success are limited. Despite the efforts of teachers, a significant portion of students continue to fail to achieve success in early literacy in school, with severe consequences for their subsequent educational progress, career opportunities and life chances. The extent of this problem varies throughout school systems. All of our children are affected by their reading ability, and as educators it is critical to provide for all students the most effective literacy programs and strategies which are research based, data-driven and successfully replicated. Because of the psychological, social and economic consequences of reading failure, it is critical to review the research to determine the risk factors that may predispose youngsters to reading failure, and the instructional practices that can be applied to ameliorate reading deficits at the earliest possible time. The failure to achieve in literacy is a fact, which continues to carry dire social and economic consequences for the children, as well as for this society. Furthermore, there is a substantial body of research indicating that schools have a narrow window of opportunity to make a difference. Students who fail to make progress in literacy during the first two years of school rarely catch up with their peers and are at-risk of becoming low achievers who are alienated from school and who dropout of education at the earliest opportunity. On the other hand, impressive empirical evidence is now available to …

The Early Music Ensemble in 21st Century America

Description: The early music ensemble has evolved from a counterculture to a mainstream musical genre. Because of this early music is having to learn arts management. Once a unique force it now competes with other arts organizations for funding and audience. Unlike other arts groups, early music has little help from within to clarify non-profit management. Through three types of surveys that were e-mailed to 239 early music organizations and 20 early music societies, an assessment of what is currently happening with early music ensembles in terms of growth, funding and over all well-being can be made. The information obtained revealed that most early music ensembles have little or no training in how to run an organization. This inexperience is creating problems and changing the face of early music. Information from the surveys also reveals that even with the economic problems over the last three years, early music is continuing to survive.

Characterization of Cure Kinetics and Physical Properties of a High Performance, Glass Fiber-Reinforced Epoxy Prepreg and a Novel Fluorine-Modified, Amine-Cured Commercial Epoxy.

Description: Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4'-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC) and by high speed DSC when the reaction rate is high. The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC, temperature-modulated DSC (TMDSC), step scan DSC and high speed DSC, thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram and a continuous heating transformation (CHT) diagram for rapid determination of processing parameters in the processing of prepregs. Shrinkage due to both resin consolidation and fiber rearrangement is measured as the linear expansion of the piston on a quartz dilatometry cell using TMA. The shrinkage of prepregs was determined to depend on the curing temperature, pressure applied and the fiber orientation. Chemical modification of an epoxy was done by mixing a fluorinated aromatic amine (aniline) with a standard aliphatic amine as a curing agent for a commercial Diglycidylether of Bisphenol-A (DGEBA) epoxy. The resulting cured network was tested for wear resistance using tribological techniques. Of the six anilines, 3-fluoroaniline and 4-fluoroaniline were determined to have lower wear than the …

Integrating GIS with Benthic Metrics: Calibrating a Biotic Index to Effectively Discriminate Stream Impacts in Urban Areas of the Blackland Prairie Eco-Region

Description: Rapid Bioassessment Protocols integrate a suite of community, population, and functional metrics, determined from the collection of benthic macroinvertebrates or fish, into a single assessment. This study was conducted in Dallas County Texas, an area located in the blackland prairie eco-region that is semi-arid and densely populated. The objectives of this research were to identify reference streams and propose a set of metrics that are best able to discriminate between differences in community structure due to natural variability from those caused by changes in water quality due to watershed impacts. Using geographic information systems, a total of nine watersheds, each representing a different mix of land uses, were chosen for evaluation. A total of 30 metrics commonly used in RBP protocols were calculated. Efficacy of these metrics to distinguish change was determined using several statistical techniques. Ten metrics were used to classify study area watersheds according to stream quality. Many trends, such as taxa presence along habitat quality gradients, were observed. These gradients coincided with expected responses of stream communities to landscape and habitat variables.

New Surveillance Technologies and the Invasion of Privacy Rights

Description: Definition of privacy has changed by the changes and improvements in information and surveillance technologies. These changes and improvement need new legal decisions for new kinds of privacy invasions. This study explores the scope of privacy right, particularly when a technological surveillance has occurred by law enforcement agencies. It focuses in particular on increasing law enforcements' surveillance technologies and devices that have the potential to impact citizens' information privacy. These increasing changes in surveillance technologies have important implications both for law enforcements and citizens. This study also discusses increasing law enforcement surveillance for the public's security, changes of the laws that allow law enforcements to use new surveillance powers as a war on terrorism, and the citizens concerns of information privacy. A particular attention is given to the recent public opinion surveys which show citizens' increasing privacy concerns. Finally, a set of recommendations to figure out security-privacy debate and reduce the privacy concerns of the citizens is offered.

The Effects of Premenstrual Syndrome Symptomatology on Marital Satisfaction

Description: 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 to compare the MSI-R scores.

Characterization of Methyltrimethoxysilane Sol-Gel Polymerization and the Resulting Aerogels.

Description: Methyl-functionalized porous silica is of considerable interest as a low dielectric constant film for semiconductor devices. The structural development of these materials appears to affect their gelation behaviors and impact their mechanical properties and shrinkage during processing. 29Si solution NMR was used to follow the structural evolution of MTMS (methyltrimethoxysilane) polymerization to gelation or precipitation, and thus to better understand the species that affect these properties and gelation behaviors. The effects of pH, water concentration, type of solvents, and synthesis procedures (single step acid catalysis and two-step acid/base catalysis) on MTMS polymerization were discussed. The reactivity of silicon species with different connectivity and the extent of cyclization were found to depend appreciably on the pH value of the sol. A kinetic model is presented to treat the reactivity of both silicon species involved in condensations separately based on the inductive and steric effects of these silicon species. Extensive cyclization in the presence of acid, which was attributed to the steric effects among numerous reaction pathways for the first time, prevents MTMS gelation, whereas gels were obtained from the two-step method with nearly random condensations. The experimental degree of condensation (DC) at the gel point using the two-step procedure was determined to be 0.86, which is considerably higher than that predicted by the current accepted theories. Both chemical and physical origins of this high value were suggested. Aerogels dried by supercritical CO2 extraction were characterized by FTIR, 13C and 29Si solid-state NMR and nitrogen sorption. The existence of three residual groups (Si-OH, Si-OCH3, and Si-OC2H5) was confirmed, but their concentrations are very low compared to silica aerogels. The low concentrations of the residual groups, along with the presence of Si-CH3, make MTMS aerogels permanently hydrophobic. To enhance applicability, MTMS aerogels were successfully prepared that demonstrated shrinkage less than 10% after supercritical …

Let His Conscience be her Guide: Ethical Self-Fashionings of Woman in Early-Modern Drama

Description: Female characters in early-modern drama, even when following the dictates of conscience, appear inextricably bound to patriarchal expectations. This paradoxical situation is explained by two elements that have affected the Renaissance playwright's depiction of woman as moral agent. First, the playwright's education would have included a traditional body of philosophical opinion regarding female intellectual and moral capacities that would have tried to explain rationally the necessity of woman's second-class status. However, by its nature, this body of information is filled with contradiction. Second, the playwright's education would have also included learning to use the rhetorical trope et utramque partem, that is arguing a position from all sides. Learning to use this trope would place the early-modern dramatist in the position of interrogating the contradictory notions of woman contained in the traditional sources. Six dramas covering over a sixty-year period from the mid-sixteenth to the early seventeenth centuries suggest that regardless of the type of work, comedy or tragedy, female characters are shown as adults seeking recognition as autonomous moral beings while living in a culture that works to maintain their dependent status. These works include an early comedy Ralph Roister Doister, a domestic tragedy A Woman Killed With Kindness, a closet drama The Tragedy of Mariam: The Fair Queen of Jewry, two romances, Cymbeline and The Winter's Tale, and a tragedy The Duchess of Malfi. What these plays suggest is that throughout early-modern drama, the female character is often depicted as resisting patriarchal demands that are inherently irrational, especially when these demands contradict ethical behavior that the culture ostensibly supports. The Renaissance playwright's depiction of woman as moral agent is encouraging in that even though the female character may not be successful within the parameters of the drama, nevertheless, the fact that her moral dilemma is described in ways that …

Resource Allocation in Mobile and Wireless Networks

Description: The resources (memory, power and bandwidth) are limited in wireless and mobile networks. Previous research has shown that the quality of service (QoS) of the mobile client can be improved through efficient resources management. This thesis contains two areas of research that are strongly interrelated. In the first area of research, we extended the MoSync Algorithm, a network application layer media synchronization algorithm, to allow play-out of multimedia packets by the base station upon the mobile client in a First-In-First-Out (FIFO), Highest-Priority-First (PQ), Weighted Fair-Queuing (WFQ) and Round-Robin (RR) order. In the second area of research, we make modifications to the DSR and TORA routing algorithms to make them energy aware routing protocols. Our research shows that the QoS of the mobile client can be drastically improved through effective resource allocation.

Perceived barriers to faculty participation in distance education at a 4-year university.

Description: 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 obvious that administrators and faculty do not place the same level of importance on motivational or inhibiting factors that may affect faculty participation in distance education. These results indicate that additional research should be accomplished to determine the basis for the disagreement among the three groups.
