Abstract Moments of Art Found in the Ordinary (open access)

Abstract Moments of Art Found in the Ordinary

This paper is an experiment using digital video to locate and identify the abstract in everyday life and nature. The abstract moment occurs when the image that is captured by video loses its connection with the original context, allowing the images to be viewed in an entirely new way. The abstract moment is initiated by a transformative instant, that instant in which perception is altered and the viewer sees the intended content of composition of light and sound. The project contains four digital videos that record the artist's progress and interests.

Adolescent Psychopathy in an Adjudicated Male Population: The Role of Sensation Seeking, Impulsivity, and Externalizing Disorders (open access)

Adolescent Psychopathy in an Adjudicated Male Population: The Role of Sensation Seeking, Impulsivity, and Externalizing Disorders

Psychopathy, as conceptualized by Cleckley (1941), describes a constellation of psychological and behavioral correlates including superficial charm, untruthfulness, lack of remorse or shame, poor judgment, and failure to learn from experience. Based on Cleckley's initial work, Hare (1991) developed a two-factor model of psychopathy. The purpose of this study was to investigate the roles that sensation seeking, impulsivity, ADHD, conduct disorder, and oppositional defiant disorder have on adolescents classified as psychopaths. The participants consisted of 79 adjudicated male adolescents in a maximum-security facility. As hypothesized, adolescent male psychopaths had higher levels of sensation seeking, impulsivity, conduct disorder and oppositional defiant disorder. A discriminant function analysis found that sensation seeking, impulsivity, ADHD, Conduct Disorder, and Oppositional Defiant Disorder was moderately useful in classifying adolescent psychopathy. The results suggest that behavioral dysregulation is an important aspect of adolescent psychopathy. The relationship of these data to theories of adolescent psychopathy is discussed.

An Analysis of Periodic Rhythmic Structures in the Music of Steve Reich and György Ligeti (open access)

An Analysis of Periodic Rhythmic Structures in the Music of Steve Reich and György Ligeti

The compositions of Steve Reich and György Ligeti both contain periodic rhythmic structures. Although periods are not usually easily perceived, the listener may perceive their combinations in a hierarchy of rhythmic structures. This document is an attempt to develop an analytical method that can account for this hierarchy in periodic music. I begin with an overview of the features of Reich's and Ligeti's music that contribute to the property of periodicity. I follow with a discussion of the music and writings of Olivier Messiaen as a precedent for the periodic structures in the music of Reich and Ligeti. I continue by consulting the writings of the Israeli musicologist Simha Arom and describing the usefulness of his ideas and terminology in the development of my method. I explain the working process and terminology of the analytical method, and then I apply it to Reich's Six Pianos and Ligeti's Désordre.

An Analysis of the Effectiveness of Computer Assisted Instruction in General Chemistry at an Urban University. (open access)

An Analysis of the Effectiveness of Computer Assisted Instruction in General Chemistry at an Urban University.

The science-major General Chemistry sequence offered at the University of Houston has been investigated with respect to the effectiveness of recent incorporation of various levels of computer technology. As part of this investigation, questionnaire responses, student evaluations and grade averages and distributions from up to the last ten years have been analyzed and compared. Increased use of web-based material is both popular and effective, particularly with respect to providing extra information and supplemental questions. Instructor contact via e-mail is also well-received. Both uses of technology should be encouraged. In contrast, electronic classroom presentation is less popular. While initial use may lead to improved grades and retention, these levels decrease quickly, possibly due to a reduction in instructor spontaneity.

An Annotated Bibliography of Mobile Agents in Networks (open access)

An Annotated Bibliography of Mobile Agents in Networks

The purpose of this thesis is to present a comprehensive colligation of applications of mobile agents in networks, and provide a baseline association of these systems. This work has been motivated by the fact that mobile agent systems have been deemed proficuous alternatives in system applications. Several mobile agent systems have been developed to provide scalable and cogent solutions in network-centric applications. This thesis examines some existing mobile agent systems in core networking areas, in particular, those of network and resource management, routing, and the provision of fault tolerance and security. The inherent features of these systems are discussed with respect to their specific functionalities. The applicability and efficacy of mobile agents are further considered in the specific areas mentioned above. Although an initial foray into a collation of this nature, the goal of this annotated bibliography is to provide a generic referential view of mobile agent systems in network applications.

Application of the Finite Element Method to Some Simple Systems in One and Two Dimensions. (open access)

Application of the Finite Element Method to Some Simple Systems in One and Two Dimensions.

The finite element method (FEM) is reviewed and applied to the one-dimensional eigensystems of the isotropic harmonic oscillator, finite well, infinite well and radial hydrogen atom, and the two-dimensional eigensystems of the isotropic harmonic oscillator and the propagational modes of sound in a rectangular cavity. Computer codes that I developed were introduced and utilized to find accurate results for the FEM eigensolutions. One of the computer codes was modified and applied to the one-dimensional unbound quantum mechanical system of a square barrier potential and also provided accurate results.

Application of Thermomechanical Characterization Techniques to Bismuth Telluride Based Thermoelectric Materials

Access: Use of this item is restricted to the UNT Community
The thermoelectric properties of bismuth telluride based thermoelectric (TE) materials are well-characterized, but comparatively little has been published on the thermomechanical properties. In this paper, dynamic mechanical analysis (DMA) and differential scanning calorimetry data for bismuth telluride based TE materials is presented. The TE materials' tan delta values, indicative of viscoelastic energy dissipation modes, approached that of glassy or crystalline polymers, were greater than ten times the tan delta of structural metals, and reflected the anisotropic nature of TE materials. DMA thermal scans showed changes in mechanical properties versus temperature with clear hysteresis effects. These results showed that the application of DMA techniques are useful for evaluation of thermophysical and thermomechanical properties of these TE materials.

Approach to Quantum Information starting from Bell's Inequality (Part I) and Statistical Analysis of Time Series Corresponding to Complex Processes (Part II)

Access: Use of this item is restricted to the UNT Community
I: Quantum information obeys laws that subtly extend those governing classical information, making possible novel effect such as cryptography and quantum computation. Quantum computations are extremely sensitive to disruption by interaction of the computer with its environment, but this problem can be overcome by recently developed quantum versions of classical error-correcting codes and fault-tolerant circuits. Based on these ideas, the purpose of this paper is to provide an approach to quantum information by analyzing and demonstrating Bell's inequality and by discussing the problems related to decoherence and error-correcting. II: The growing need for a better understanding of complex processes has stimulated the development of new and more advanced data analysis techniques. The purpose of this research was to investigate some of the already existing techniques (Hurst's rescaled range and relative dispersion analysis), to develop a software able to process time series with these techniques, and to get familiar with the theory of diffusion processes.

Approaches to Nature Aesthetics: East Meets West (open access)

Approaches to Nature Aesthetics: East Meets West

Nature aesthetics is examined as an approach to environmental ethics. The characteristics of proper nature appreciation show that every landscape can be appreciated impartially in light of the dynamic processes of nature. However, it is often claimed that natural beauty decreases if humans interfere into nature. This claim leads to the separation of human culture and nature, and limits the number of landscapes which can be protected in terms of aesthetic value. As a solution to this separation, a non-dualistic Japanese aesthetics is examined as a basis for the achievement of the coexistence of culture and nature. Ecological interrelationships between human culture and nature are possible by means of an aesthetic consciousness in terms of non-hierarchical attitudes.

Automatic Software Test Data Generation

Access: Use of this item is restricted to the UNT Community
In software testing, it is often desirable to find test inputs that exercise specific program features. Finding these inputs manually, is extremely time consuming, especially, when the software being tested is complex. Therefore, there have been numerous attempts automate this process. Random test data generation consists of generating test inputs at random, in the hope that they will exercise the desired software features. Often the desired inputs must satisfy complex constraints, and this makes a random approach seem unlikely to succeed. In contrast, combinatorial optimization techniques, such as those using genetic algorithms, are meant to solve difficult problems involving simultaneous satisfaction of many constraints.

A Behavioral Economic Analysis of the Effects of Unit Price Sequence on Demand for Money in Humans. (open access)

A Behavioral Economic Analysis of the Effects of Unit Price Sequence on Demand for Money in Humans.

Three groups of participants were exposed to different unit price sequences. Unit prices for all groups ranged from unit price 1 to 21. Analyses of demand curves, response rates, session duration, and elasticity coefficients suggest that the sequence of exposure to unit prices can affect the elasticity of demand. In addition, the size of unit price contrast, direction of unit price change, and proximity to experimental milestones also may affect the consumption of monetary reinforcers.

Better Teaching Model? Middle School Science Classroom Using the 4MAT Instructional Strategy vs. Lessons Created Without this Model (open access)

Better Teaching Model? Middle School Science Classroom Using the 4MAT Instructional Strategy vs. Lessons Created Without this Model

The problem investigated was the need for effective and efficient learning for middle school science students to meet expectations set in Goals 2000. The use of the 4MAT Instructional Method was investigated as a possible method for attainment of current science standards. The study included one middle school science instructor's classes with 89 participating students. Measurements were taken and comparisons drawn using three assessment methods to determine if improved academic achievement and attitude scores resulted. Data analysis yielded no significant conclusion in either academic achievement or attitude improvement; however, observations of the researcher indicated potential usefulness of the 4MAT approach. The t-value calculated in the assessment methods was insufficient with a .05 probability of error present in the findings. The limitations of the study skewed the results and outweighed the possible observational insight.

Beyond GNP: Economic Freedom as a Determinant of Basic Human Needs. (open access)

Beyond GNP: Economic Freedom as a Determinant of Basic Human Needs.

Research concerning ‘basic needs' in the Human Rights literature has consistently found a positive and significant relationship between measures of wealth and basic needs provision. This study utilizes a relatively new measure of economic freedom to test hypotheses regarding general macro-economic policy decisions and basic needs outcomes. A pooled dataset of 138 countries over four years is examined using OLS panel regression controlling for both' year' and ‘country,' in a standard basic needs model. Consistent and systematic differences between economic freedom effects in OECD nations and non-OECD nations are revealed. The Economic Freedom Index has both theoretical and empirical advantages over previous measures of wealth and economic freedom, allowing human rights scholars to test specific economic policy decisions as they affect basic needs outcomes.

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill (open access)

Bioreactor Landfill Cell Feasibility Study ' Reference to City of Denton Subtitle-D Permit #1590A Landfill

The City of Denton Landfill, Permit #1590A, utilizes “Dry-Tomb” techniques for disposal and promotion of municipal solid waste stabilization, as described by the Resource Conservation and Recovery Act (RCRA) prohibition in 40 CFR. Bioreactor research suggests re-circulating leachate increases biodegradation rates and reduces long-term monitoring from fifty years to less than ten years. Current procedures that are followed at Denton's landfill, literature review and the use of the Hydrologic Evaluation of Landfill Performance (HELP) model, suggest that a bioreactor landfill cell is worthy of further research. Re-circulating leachate and augmenting it with additional liquid will increase biodegradation and the need to design and build a landfill gas collection system to capture methane for energy recovery uses.

Breaking Through: A Composition for Symphony Orchestra

Access: Use of this item is restricted to the UNT Community
Breaking Through is a single-movement composition for symphony orchestra based on a fourteen-note melody. Every harmonic and melodic figure except the bass line is derived from this source melody. The structure of the work is based on a number of musical dichotomies that work on both local and large-scale levels. The local dichotomies contrast consonance with dissonance and ambiguity with clarity (in respect to texture and rhythm). The dichotomy of two-part form versus three-part form and the dichotomy of simplicity versus complexity operate on the large scale. The unity lended by the single source melody coupled with the contrasts furnished by the aforementioned dichotomies allow Breaking Through to be both coherent and interesting.

A Case Study on Police Misconduct in the United States of America and an Applicable Model for the Turkish National Police. (open access)

A Case Study on Police Misconduct in the United States of America and an Applicable Model for the Turkish National Police.

This study explores the underlying causes and deterrent control mechanisms of police misconduct in the United States. Outcomes of causes and control mechanisms constitute the basis for an applicable model for the Turkish National Police (TNP). Why is some police behavior deviate? What are the main determinants of police misconduct? Is police misconduct a result of sociological behavior and subcultural development within police organizations or a psychological behavior as an outcome of officers' personal traits? What are the control mechanisms for police misconduct? What are their strengths and weaknesses? Do they deter or not? Is there a control mechanism that deters better than others? What is the best deterrence model for the TNP?

Changing Ideological Boots:  Adaptive Legislator Behavior in Changing Districts (open access)

Changing Ideological Boots: Adaptive Legislator Behavior in Changing Districts

Congressional roll-call votes are often used to investigate legislative voting behavior. To depict adaptive roll-call behavior in response to demographic changes that occur during redistricting, I use issue specific interest group scores from the ADA, NFU, and COPE. This exploits the bias in the selection of the issues that interest groups utilize to rate U.S. representatives, by using them to reflect changes in response to significant demographic fluctuations in the constituency population. The findings indicate that while party is the most significant factor in whether legislators adapt their voting in favor of certain groups, they do notice group composition changes within district and adapt their voting accordingly. This illustrates the impact of redistricting on policy and legislators' adaptation to changes in district composition.

Changing Privacy Concerns in the Internet Era.

Access: Use of this item is restricted to the UNT Community
Privacy has always been a respected value regardless of national borders, cultural differences, and time in every society throughout history. This study focuses on the unprecedented changes in the traditional forms of privacy and consequent concerns with regard to invasion of privacy along with the recent emergence and wide use of the Internet. Government intrusion into private domains through the Internet is examined as a major concern. Privacy invasions by Web marketers, hacker threats against privacy, and employer invasion of employee privacy at the workplace are discussed respectively. Then a set of possible solutions to solve the current problems and alleviate the concerns in this field is offered. Legal remedies that need to be performed by the government are presented as the initial solution. Then encryption is introduced as a strong technical method that may be helpful. Finally, a set of individual measures emphasized as complementary practical necessities. Nevertheless, this study indicates that technology will keep making further changes in the form and concerns of privacy that possibly may outdate these findings in the near future, however, privacy itself will always remain as a cherished social value as it has always been so far.

Characteristics of Community Service Programs and Probationers in Texas (open access)

Characteristics of Community Service Programs and Probationers in Texas

As a criminal sanction, community service involves unpaid labor on the part of convicted criminal offenders. Community service was created as an alternative to incarceration for low-level offenders. It now appears, however, that community service is rarely used as a true alternative to prison, but rather as an added condition of probation. The body of research on community service in the United States is modest, so relatively little is known about its characteristics and administration. Data were attained from 88 Texas probation professionals via self-administered written surveys in an effort to gather information about the use of community service as a criminal sanction in Texas. Frequency distribution analyses identified characteristics of both community service programs and offender participants in Texas.

Civil Asset Forfeiture in the Fight Against Drugs (Policy Analysis) (open access)

Civil Asset Forfeiture in the Fight Against Drugs (Policy Analysis)

Even if the main criminals of an organization are incarcerated, they will be replaced by others who would continue illegal activities, unless their financial assets are removed. Thus, civil forfeiture intends to dismantle the economic infrastructure of drug trafficking networks. Civil forfeiture considers the property as guilty, rather than the owner, and it may exist even if there is not a criminal action. Therefore, it is claimed that police agencies have chosen easy targets, such as wealthy drug users rather than major drug traffickers. Consequently, it has been particularly challenged on the basis of the Excessive Fines, Double Jeopardy, and Due Process Clauses. The use of criminal forfeiture instead of civil forfeiture and the elimination of the equitable sharing provision are considered to be the primary solutions.

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.

College Freshman Biology Two Semester Course: Integrating Deep Processing Teaching Techniques

Development of a college level freshman biology course was undertaken in response to government reports that American students have fallen behind students of other countries in the area of the sciences. Teaching strategies were investigated to accomplish two objectives, to define essential academic material to include in the course and to investigate teaching techniques that would increase deep processing of the information. An active process that consisted of applying the cognitive information to solving problems or developing answers to questions was defined as critical thinking. Critical thinking was incorporated into the course by the use of case studies.
