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.

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.

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.

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.

Effects of Hedonic and Utilitarian Shopping Satisfaction on Mall Consumption

Access: Use of this item is restricted to the UNT Community
The modern consumer expects a consumption experience with both hedonic and utilitarian rewards during a single visit to the mall. The orchestrating of both hedonic and utilitarian benefits in one visit challenges mall management and retailers to deliver the maximum shopping experience. This study seeks to reveal relationships among six variables: demographic characteristics, mall shopping orientation, mall perception, hedonic satisfaction, utilitarian satisfaction, and mall consumption. The intercept survey was conducted at a major entertainment-themed mall in north Texas. Multiple regression analyses (N = 202) indicate that demographic characteristics and mall shopping orientation were significant predictors of mall perception. Also, two mall perception factors (Sensation and Physical Environment) were predictors of hedonic and utilitarian mall shopping satisfaction. However, hedonic and utilitarian mall shopping satisfaction were found not to predict mall consumption in terms of cross-shopping, money spent, and time spent.

Fabrication of MOS capacitor and transitor structure using contact photolithography.

Access: Use of this item is restricted to the UNT Community
This problem in lieu of thesis report describes a practical photolithographic method to produce micro patterns on metal-oxide-semiconductor or metal-oxide-semiconductor-metal layers for electrical measurements. The desired patterns are then transferred from the photo mask to the photoresist-coated metal film by exposure, followed by wet etching. In the procedure described in this report, it was observed that microstructures as small as 27 mm with an edge roughness of ~ 2 mm can be reproducibly generated with this process. MOS capacitors and transistors structures can be fabricated by using this technique. The method described in this report requires access to only simple facilities so that it is relatively inexpensive, and the overall time required for the whole process is short.

Implementation of Scalable Secure Multicasting

Access: Use of this item is restricted to the UNT Community
A large number of applications like multi-player games, video conferencing, chat groups and network management are presently based on multicast communication. As the group communication model is being deployed for mainstream use, it is critical to provide security mechanisms that facilitate confidentiality, authenticity and integrity in group communications. Providing security in multicast communication requires addressing the problem of scalability in group key distribution. Scalability is a concern in group communication due to group membership dynamics. Joining and leaving of members requires the distribution of a new session key to all the existing members of the group. The two approaches to key management namely centralized and distributed approaches are reviewed. A hybrid solution is then provided, which represents a improved scalable and robust approach for a secure multicast framework. This framework then is implemented in an example application of a multicast news service.

Mechanical Properties of Polymer Modified Mortar

Access: Use of this item is restricted to the UNT Community
The mechanical properties of the polymer-modified mortar are markedly improved over conventional cement mortar. We utilized recycled ABS in powder form and a polymer latex emulsion, polymer percentage ranges from 0 to 25 percent by polymer/cement ratio were investigated. The mechanical properties investigated were compression strength and adhesion strength. Compression strength effects did not have an impact on adhesion strength. Adhesion strength was calculated with pullout testing apparatus designed by the author. Results indicate that recycled ABS had a lower adhesive strength than the acrylic latex emulsion and the base mortar, but did increase in adhesive strength when mixed with maleic-anhydride. The adhesive strength was investigated for a Fiber Reinforced Polymer (FRP) made of an "E" glass fiber that is a continuous strand roving oriented and pre-tensioned longitudinally in an isopthalic polyester matrix material. The FRP rebar was compared to standard steel rebars, and found that the standard steel corrugated rebar had a higher adhesive strength, due to mechanical interlocking. This was clarified by measurements using a smooth steel rebar. Characterization of the polymer-modified mortar was conducted by pore analysis and scanning electron microscopy. Scanning Electron Microscopy was implemented to view the polymer particles, the cement fibrils formed by the …

Use of Satellite Imagery and GIS to Model Brood-Rearing Habitat for Rio Grande Wild Turkey Populations Occurring in the Western Cross Timbers Region of Texas

Access: Use of this item is restricted to the UNT Community
Remote sensing and GIS have become standard tools for evaluating spatial components of wildlife habitats. These techniques were implemented to evaluate Rio Grande wild turkey (Meleagris gallopavo) poult-rearing habitat in the Western Cross Timbers region of Texas. Texas Parks and Wildlife (TPWD) random roving turkey counts for 1987-1989 and 1998-2000 were selected, indicating locations where hens with poults were observed. Satellite imagery from 1988 and 1999 was classified and then processed with Patch Analyst. To add robustness, stream, road and census population densities were also evaluated for each turkey location. Analysis of the 1988 canopy cover image, comparing observed locations with randomly-selected habitat cells (N = 20) indicated significant differences (p <.05) for patch edge variables. Mean patch edge was significantly greater for habitat locations where hens with poults were observed than for those selected at random. Spatial data for 1999 did not indicate a significant difference (p < .05) between sampling groups (observed vs. random, N = 30). Significant differences (p <.05) did occur for turkey locations observed in both 1988 and 1999 (N = 7). This demonstrates the adaptability of wild turkey hens, as habitats change over time, hens continued to visit the same locations even though the …

An Analysis of Major American Riots: Issues in Riots and Riot Control

Access: Use of this item is restricted to the UNT Community
By conducting sound research to understand the concepts surrounding rioting and efficient riot response tactics, professionals, especially whose main job is to ensure the tranquility in the society, will be better prepared to deal with all kinds of civil movements. The purpose of this study, consequently, is to meet the growing need for educational materials in this area and to provide riot response case studies, which demonstrate the numerous administrative challenges faced by law enforcement decision makers. In this study, seven major riots from throughout the United States are discussed including the Hay Market Riot of 1886, the Watts Riot of 1965, and Los Angeles Riots of 1992. Each riot case is studied in five different and independent stages: the setting and pre-disturbance situation, basic causes of the event, the disturbance situation, the response to the riot, and the aftermath of the incident. The study of all of these stages is intended to help police administrators acquire a general perspective on collective violence, and help them prevent future occurrences in their jurisdictions. In this thesis a special reference is given to the deficiencies of American riot policing and some recommendations were formed accordingly. Therefore, the study concludes with a list …

A Case Study of Leftist Terrorism in Turkey

Access: Use of this item is restricted to the UNT Community
Change in government has characterized the development of most nations. Sometimes this change has been marked by continued evolution, in a peaceful attempt to move forward. Other times, change has been fraught with violent revolution and terrorism. This process has been the subject of much debate by political scientists and economic philosophers. Today, Turkey suffers from continued threats to its government through violent acts of terrorism conducted by various groups, expressing ideologies of leftist and rightist organizations, as well as ethnic and religious extremists. This thesis examines DHKP/C as the primary leftist revolutionary group effecting Turkey, exploring its historical background in Europe and the Middle East, as well as its philosophical link to Marxism. Further, this treatise discusses the implication of revolution and terrorism expressed by DHKP/C; and explores innovative and peaceful solutions, strategies, and techniques to be used by the police forces of Turkey in combating this group

Comparison of GPS Point Selection Methods for GIS Area Measurement of Small Jurisdictional Wetlands

Access: Use of this item is restricted to the UNT Community
U.S. Army Corps of Engineers (USACE) regulates fill of jurisdictional waters of the United States including wetlands. Recent USACE regulations set a threshold of impacts to wetlands at one-half acre. Impact area can be determined by Global Positioning System (GPS) measurement of wetland boundary and Geographic Information System (GIS) calculation of impact area. GPS point selection methods include (1) equal time interval, (2) transect and (3) intuition. Four two-acre shapes were measured with each GPS method and brought into GIS for area calculation. Analysis of variance and Root Mean Square Error analyses determine that the transect method is an inferior point selection method in terms of accuracy and efficiency.

Condom Use Among College Students

Access: Use of this item is restricted to the UNT Community
With the spread of the Human Immuno-Deficiency Virus and sexually transmitted diseases, it is extremely important for sexually active individuals to protect themselves properly if they decide to engage in sexual intercourse. Knowledge of HIV and the Acquired Immune Deficiency Syndrome has been associated with safer sexual practices, but knowledge alone does not totally explain risky sexual practices. This study examined how 154 college students' knowledge of HIV/AIDS, relationship status, perceptions of condom use, and perceptions of personal risk affect condom use during sexual intercourse. The impact of trust and love justifications along with the approval of peers were also examined. Perceptions of condom use and perceptions of personal risk were compared by gender and ethnicity; how perception of personal risk is related to condom use and condom use intentions was also examined. Condom use intention was found to be a significant predictor of condom use, and a significant difference of means for condom use intentions was reported between individuals who used condoms during their last experience with sexual intercourse and those who did not use condoms during their last sexual experience
