Unity: When the Two Become One (open access)

Unity: When the Two Become One

Jewelry has been used as a gift exchange between lovers for many centuries. It has been conveyed in a variety of forms to symbolize the meaning of love. This body of work is associated with glory of love, of sexual experience between lovers representing the idea of unity when two parts become one unit, not only in the physical sense, but also in the psychical sense. The works were divided into three series including three pair of rings, two pair of lockets, and five pair of necklaces. The erotic expression has been addressed on every piece in an abstract way counting design motifs, material used, and interaction within the piece itself. Moreover, each piece has romantic meanings and essential aspects as a symbol of love.

A Validation Study of a Writing Skills Test for Police Recruit Applicants (open access)

A Validation Study of a Writing Skills Test for Police Recruit Applicants

This study evaluated the effectiveness of a direct test of higher-order and lower-order writing abilities needed for police report writing. This test was specifically designed to address report writing deficiencies experienced by police in the training academy. Descriptive statistics were examined, and relationships between this test and writing ability dimensions included on a separate, indirect, multiple choice test were investigated. Direct and indirect scores were correlated with training academy performance. Because both tests assessed higher-order and lower-order writing abilities, comparisons were made to determine which type of test was most appropriate for assessing the different types of writing skills. Results indicated that the direct test was a valid predictor of academy performance. Direct methods of measurement were found to be better than indirect methods for assessing higher-order writing skills. For lower-order writing skills, the indirect method appeared to be a better measure than the direct method.

Vicarious Learning: The Relationship Between Perceived Leader Behavior and Work Group Member Behavior (open access)

Vicarious Learning: The Relationship Between Perceived Leader Behavior and Work Group Member Behavior

The relationship between perceived leader behavior and work group behavior was examined. Archival survey data was used in the analyses. The company that developed the survey randomly selected 595 employees to complete the survey. Results suggest there is a strong and significant relationship between leader and subordinate behavior. Group members who report that their leader demonstrates a particular behavior also report that their work group demonstrates the same or similar behavior, suggesting that subordinates may be modeling the behavior of their leader. Leadership behaviors related to trust, availability, respect, conflict, and support seem to be the best predictors of work group behavior. Furthermore, whether or not group members have received team training appears to have an effect on their perceptions of their leader and work group. The challenge for leaders is to understand modeling principles so that they can facilitate the modeling of functional rather than dysfunctional behaviors.

Water Quality Mapping on Lake Texoma USA (open access)

Water Quality Mapping on Lake Texoma USA

The primary objective of this study was to develop and evaluate a system capable of rapid, continuous collection of water quality and locational data on Lake Texoma. Secondary objectives included developing monthly distribution maps for chlorophyll-a, turbidity, and specific conductivity in Lake Texoma and investigating the spatial and temporal relationships between these common water quality indicators. A modified YSI multiprobe was used to develop a system capable of surveying the lake within 4 days with samples at 330 to 400 meter intervals. Data generated with this system compared favorably with previous studies of Lake Texoma. Two sets of raster format maps were developed for the monthly distributions of chlorophyll-a, turbidity, and specific conductivity across the lake. Spatial and temporal relationships generally took the form of decreasing gradients running from the lake arms towards the Main Lake Zone in the case of chlorophyll-a and turbidity. Or, in the case of specific conductivity, a decreasing gradient from the Red River arm to the Washita River arm. All three water quality indicators were strongly influenced by river discharge levels.

Worker-initiated violence: Prevention strategies in park and recreation departments (open access)

Worker-initiated violence: Prevention strategies in park and recreation departments

Workplace violence infects many organizations. This descriptive study assesses the extent to which Texas park and recreation departments institute policies and procedures for preventing worker-initiated violence. Thirty directors from local park and recreation departments were interviewed by telephone and asked to identify whether their departments used specific prevention strategies to thwart instances of worker-initiated violence. The findings reveal few prevention strategies being used and suggest a need for park and recreation managers to increase their awareness and take a more proactive approach to violence prevention.

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.

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.

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.

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.

Community Policing Training Programs and Their Roles in Implementation of Community Policing (open access)

Community Policing Training Programs and Their Roles in Implementation of Community Policing

The main goal of this study is to indicate the importance of community policing training programs for implementation of community policing. Community policing requires a transition from traditional policing methods to proactive and problem-oriented policing which is constructed upon police-citizen partnership. For the successful implementation of community policing, the change process needs to be fully realized throughout the organization. Suitably appropriate methods of training will help both officers and citizens to fully understand the goals of community policing. This study focuses on the types of existing community training methods as well as the obstacles that complicate training efforts. Consequently, this study provides some recommendations on community policing training programs to make them more helpful for police departments.

Comparative Analysis of Interrelations Between Democracy and Democratic Policing Practices (open access)

Comparative Analysis of Interrelations Between Democracy and Democratic Policing Practices

It is assumed that democratic policing will help to improve the respect of human rights and democracy in a given country. Using secondary data, this study explores cross-nationally the interrelation between democratic policing practices (e.g., community policing) and democracy and human rights.The results show significant positive correlation between the practice of democratic policing and indicators of democracy and respect for human rights. The analysis strongly implies that scholars have underestimated the power of policing institutions in democratic societies.

Comparing Five Empirical Biodata Scoring Methods for Personnel Selection (open access)

Comparing Five Empirical Biodata Scoring Methods for Personnel Selection

A biodata based personnel selection measure was created to improve the retention rate of Catalog Telemarketing Representatives at a major U.S. retail company. Five separate empirical biodata scoring methods were compared to examine their usefulness in predicting retention and reducing adverse impact. The Mean Standardized Criterion Method, the Option Criterion Correlation Method, Horizontal Percentage Method, Vertical Percentage Method, and Weighted Application Blank Method using England's (1971) Assigned Weights were employed. The study showed that when using generalizable biodata items, all methods, except the Weighted Application Blank Method, were similar in their ability to discriminate between low and high retention employees and produced similar low adverse impact effects. The Weighted Application Blank Method did not discriminate between the low and high retention employees.

A comparison of moral reasoning and moral orientation of American and Turkish university students. (open access)

A comparison of moral reasoning and moral orientation of American and Turkish university students.

This study compares American and Turkish male and female university students in terms of moral orientation (justice and care) and Kohlberg's stages of moral reasoning to examine the influence of culture and gender on moral development. A total of 324 undergraduate students between the ages of 18 and 46 are administered the Defining Issues Test (DIT) and the Measure of Moral Orientation (MMO). Statistical analyses indicate Turkish participants reflect more postconventional reasoning, while American participants reflect more conventional reasoning, particularly Stage 4 reasoning. Analyses also reveal Turkish participants reflect significantly more care orientation and more justice orientation compared to American participants. These findings are discussed in terms of cultural and gender influences in moral decision-making.

Computer Crime as a Barrier to Electronic Commerce: New Solutions for Public Law Enforcement.

Access: Use of this item is restricted to the UNT Community
Electronic commerce was expected to grow exponentially, but the actual rate of growth in recent years has been disappointing. Recent surveys of perceptions of the development of electronic commerce clearly focus our attention on the perception and fear of computer crime as the major cause of this disappointing growth pattern. The thesis critiques existing private law solutions to this problem and argues from a normative theory on “the commons” for the application of new public law enforcement solutions in the public trust, sanctions, and public coproduction of order. The thesis argues that given the failures of existing private law solutions to the problem, these public law enforcement solutions should be more effective, efficient, and more satisfactory.

Control Mechanisms and Recovery Techniques for Real-Time Data Transmission Over the Internet. (open access)

Control Mechanisms and Recovery Techniques for Real-Time Data Transmission Over the Internet.

Streaming multimedia content with UDP has become popular over distributed systems such as an Internet. This may encounter many losses due to dropped packets or late arrivals at destination since UDP can only provide best effort delivery. Even UDP doesn't have any self-recovery mechanism from congestion collapse or bursty loss to inform sender of the data to adjust future transmission rate of data like in TCP. So there is a need to incorporate various control schemes like forward error control, interleaving, and congestion control and error concealment into real-time transmission to prevent from effect of losses. Loss can be repaired by retransmission if roundtrip delay is allowed, otherwise error concealment techniques will be used based on the type and amount of loss. This paper implements the interleaving technique with packet spacing of varying interleaver block size for protecting real-time data from loss and its effect during transformation across the Internet. The packets are interleaved and maintain some time gap between two consecutive packets before being transmitted into the Internet. Thus loss of packets can be reduced from congestion and preventing loss of consecutive packets of information when a burst of several packets are lost. Several experiments have been conducted with …

The Design and Implementation of a Prolog Parser Using Javacc (open access)

The Design and Implementation of a Prolog Parser Using Javacc

Operatorless Prolog text is LL(1) in nature and any standard LL parser generator tool can be used to parse it. However, the Prolog text that conforms to the ISO Prolog standard allows the definition of dynamic operators. Since Prolog operators can be defined at run-time, operator symbols are not present in the grammar rules of the language. Unless the parser generator allows for some flexibility in the specification of the grammar rules, it is very difficult to generate a parser for such text. In this thesis we discuss the existing parsing methods and their modified versions to parse languages with dynamic operator capabilities. Implementation details of a parser using Javacc as a parser generator tool to parse standard Prolog text is provided. The output of the parser is an “Abstract Syntax Tree” that reflects the correct precedence and associativity rules among the various operators (static and dynamic) of the language. Empirical results are provided that show that a Prolog parser that is generated by the parser generator like Javacc is comparable in efficiency to a hand-coded parser.

Developing a Test Bed for Interactive Narrative in Virtual Environments

Access: Use of this item is restricted to the UNT Community
As Virtual Environments (VE) become a more commonly used method of interaction and presentation, supporting users as they navigate and interact with scenarios presented in VE will be a significant issue. A key step in understanding the needs of users in these situations will be observing them perform representative tasks in a fully developed environment. In this paper, we describe the development of a test bed for interactive narrative in a virtual environment. The test bed was specifically developed to present multiple, simultaneous sequences of events (scenarios or narratives) and to support user navigation through these scenarios. These capabilities will support the development of multiple users testing scenarios, allowing us to study and better understand the needs of users of narrative VEs.
