Workplace Violence Prevention Training: An Analysis of Employees' Attitudes
The purpose of this study was to determine employees' attitudes and perceptions toward the effectiveness of workplace violence prevention training within a U.S. Government service agency with 50 offices located in Minnesota and Wisconsin. Chapter 1 presents an overview of the phenomenon of workplace violence, the movement toward prevention programs and policies and the implementation of prescreening processes during hiring and violence prevention training. Chapter 2 contains a thorough review of pertinent literature related to violence prevention training and the impact of occupational violence on organizations. This topic was worthy of research in an effort to make a significant contribution to training literature involving organizational effectiveness due to the limited amount of research literature covering the area of corporate violence prevention training and its effect on modifying attitudes and behaviors of its customers. The primary methodology involved the assessment of 1000 employees concerning their attitudes and perceptions toward the effectiveness of workplace violence prevention training. The research population were administered a 62 item online assessment with responses being measured, assessed, and compared. Significant differences were found calling for the rejection of the three study hypotheses. Chapter 4 described the findings of the population surveyed and recommendations were identified in Chapter …

Nigerian Military Government and Press Freedom, 1966-79
The problem of this thesis is to examine the military-press relationship in Nigeria from 1966 to 1979 and to determine whether activities of the military government contributed to violation of press freedom by prior restraint, postpublication censorship and penalization. Newspaper and magazine articles related to this study were analyzed. Interviews with some journalists and military personnel were also conducted. Materials collected show that the military violated some aspects of press freedom, but in most cases, however, journalists were free to criticize government activities. The judiciary prevented the military from arbitrarily using its power against the press. The findings show that although the military occasionally attempted suppressing the press, there are few instances that prove that journalists were denied press freedom.

Practical Evaluation of a Software Defined Cellular Network
This thesis proposes a design of a rapidly deployable cellular network prototype that provides voice and data communications and it is interoperable with legacy devices and the existing network infrastructure. The prototype is based on software defined radio and makes use of IEEE 802.11 unlicensed wireless radio frequency (RF) band for backhaul link and an open source GSM implementation software. The prototype is also evaluated in environments where there is limited control of the radio frequency landscape, and using Voice Over Internet Protocol (VoIP) performance metrics to measure the quality of service. It is observed that in environments where the IEEE 802.11 band is not heavily utilized, a large number of calls are supported with good quality of service. However, when this band is heavily utilized only a few calls can be supported as the quality of service rapidly degrades with increasing number of calls, which is due to interference. It is concluded that in order to achieve tolerable voice quality, unused licensed spectrum is needed for backhaul communication between base stations.

Instructional Personnel Perceptions on Integrating Instructional Technology in K-12 Classrooms: A Case Study
Integrating digital pedagogy into instruction in a manner that promotes critical thinking and drives increased student achievement and engagement in all classrooms is a goal of many campuses and districts that invest heavily in hardware, software, and professional development on an annual basis. Digital pedagogy goals tend to center around preparing students for the 21st century workforce, promoting instruction that is more engaging, and providing deeper learning for all students; however, achieving these goals is not possible without teachers willing and able to effectively implement instructional technology into the content they are teaching. The conceptual framework consists of digital leadership, teacher engagement, and resources and supports. This case study focused on the district-wide integration of technology into instruction through the elements found in the conceptual framework. Educators, from kindergarten through twelfth grade were surveyed about their attitudes, self-efficacy perceptions and willingness to integrate digital pedagogies into their current teaching practices. The online survey that utilized Likert-like scales to gather demographic information as well educator perceptions on digital integration, teaching philosophy, digital self-efficacy, and leadership's focus and expectations regarding instructional technology. Additional data, from a variety of district documents, was also gathered on leadership, professional development, and infrastructure supports utilized to …

Question of Honor
My thesis, Question of Honor, addresses the premise of women's lack of choice in relation to men's honor, and vengeance; concepts that are closely connected to the oppressive world of women in Pakistan. These works deal with concepts of purity and minor transgressions that have an impact on the lives of women in relation to family names and the associative feelings of humiliation linked to men. The subtle nuances of women and their reactions to oppression give a strong emotive content to the work.

Present tense marking as a synopsis of Southern American English: Plural verbal -s and zero 3rd singular.
This thesis explores the evolution plural verbal -s ("People thinks he is guilty") and zero 3rd singular ("He think he is guilty") in data from two sources on Southern English: The Linguistic Atlas of the Gulf States (LAGS) and The Linguistic Atlas of the Middle and South Atlantic States (LAMSAS). The research questions that underlie this study consider (1) the demographic association of plural verbal -s and zero 3rd singular, (2) the maintenance of each form, (3) the constraints on their use, and (4) the origins of -s variability. The atlas data suggest the following for plural verbal -s: (1) it has a British source, (2) it was present in both African American Vernacular English (AAVE) and early Southern White English (SWE), and (3) there were different grammatical constraints on its use in AAVE and SWE. Data for zero 3rd singular -s suggest this form (1) did not have a British source and (2) that it has historically been an AAVE feature.

Family Structure and Marijuana Use Among Adolescents
Family structure as a predictive variable of juvenile delinquency has been studied for the last hundred years. This relationship originated due to societal belief that divorce was detrimental to adolescents. Due to the changing societal roles in the United States, family structure has been changing. More children are growing up in non-intact families, such as single-parent households, households with stepparents, cohabitating families, and households without a parent present. To study the effect family structure has on juvenile delinquency, researchers have utilized social control theory, differential association, self-control theory and general strain theory to conceptualize variables to explain why family structure influences delinquent behavior. A review of previous literature on this topic indicates that living in intact households, which are households with two biological parents who are married, have, on average, the lowest rates of delinquency. This thesis investigates the relationship between family structure and lifetime marijuana use among eighth and tenth grade adolescents in the United States through the use of secondary data analysis of Monitoring the Future Study, 2012. The results provide support for the relationship between family structure and lifetime marijuana use.

Interpersonal Factors Related to the Pursuit of a Higher Education Among First Generation Undergraduate Students
The typical educational stressors experienced by college students, in conjunction with developmental stressors such as separation from parents, individuation, and perceived social support, can interact to impact adaptation significantly. First generation college students (students who are the first in their family to attend college) can experience stressors beyond the typical educational stressors experienced by later generation college students, including lack of support from family and peers as well as financial difficulties that can interact to impact the pursuit of an education beyond the undergraduate level. The present study examined factors that may be especially influential in the pursuit of a higher education for first generation college students. Results indicated that aspects of family enmeshment were related to academic motivation for first generation students, but not for later generation students. Exploratory analysis showed that family and finances were mentioned more often among first generation students when compared to later generation students as stressors that strongly influence the desire to continue beyond the undergraduate level.

Ozone Pollution of Shale Gas Activities in North Texas
The effect of shale gas activities on ground-level ozone pollution in the Dallas-Fort Worth area is studied in detail here. Ozone is a highly reactive species with harmful effects on human and environment. Shale gas development, or fracking, involves activities such as hydraulic fracturing, drilling, fluid mixing, and trucks idling that are sources of nitrogen oxides (NOX) and volatile organic compounds (VOC), two of the most important precursors of ozone. In this study two independent approaches have been applied in evaluating the influences on ozone concentrations. In the first approach, the influence of meteorology were removed from ozone time series through the application of Kolmogorov-Zurbenko low-pass filter, logarithmic transformation, and subsequent multi-linear regression. Ozone measurement data were acquired from Texas Commission on Environmental Quality (TCEQ) monitoring stations for 14 years. The comparison between ozone trends in non-shale gas region and shale gas region shows increasing ozone trends at the monitoring stations in close proximity to the Barnett Shale activities. In the second approach, the CAMx photochemical model was used to assess the sensitivity of ozone to the NOX and VOC sources associated with shale oil and gas activities. Brute force method was applied on Barnett Shale and Haynesville Shale emission …

Journey for Jazz
This written thesis accompanies a 32-minute documentary video, Journey for Jazz, which explores four Korean students who major in jazz at the University of North Texas in Denton. Detailed accounts of the pre-production, production, and post-production of the video guide the reader to understand the challenging and rewarding process of making this documentary. Theoretical issues are also discussed, including Bill Nichols's typology of documentary modes as a useful tool for analysis of hybrid documentaries and conventions of the observational and interactive mode in Journey for Jazz, which is considered a hybrid of both modes. The film focuses mainly on the scholarly and artistic experiences that the four students undergo while studying jazz in the United States.

General Satisfaction of Students in 100% Online Courses in the Department of Learning Technologies at the University of North Texas
The purpose of this study was to examine whether there are significant relationships between the general satisfaction of students and learner-content interaction, learner-instructor interaction, learner-learner interaction, and learner-technology interaction in 100% online courses. There were 310 responses from the students. This study did not use data from duplicate students and instructors. Excel was used to find duplicate students and instructors; therefore, 128 responses were deleted. After examination of box plots, an additional four cases were removed because they were outliers on seven or more variables. Nineteen responses were deleted because they did not answer all questions of interest, resulting in a total sample of 159 students. Multiple regression analysis was used to examine the relationship between the four independent variables and the dependent variable. In addition to tests for statistical significance, practical significance was evaluated with the multiple R2 , which reported the common variance between independent variables and dependent variable. The two variables of learner-content and learner-instructor interaction play a significant role in predicting online satisfaction. Minimally, the variable learner-technology can predict online satisfaction and is an important construct that must be considered when offering online courses. Results of this study provide help in establishing a valid and reliable …

An Analytical Study of the Variations on the Theme of Paganini's Twenty-Fourth Caprice, Op. 1 by Busoni, Friedman, and Muczynski
The purpose of this study is to analyze sets of variations on Paganini's theme by three twentieth-century composers: Ferruccio Busoni, Ignaz Friedman, and Robert Muczynski, in order to examine, identify, and trace different variation techniques and their applications. Chapter 1 presents the purpose and scope of this study. Chapter 2 provides background information on the musical form "theme and variations" and the theme of Paganini's Twenty-fourth Caprice, Op. 1. Chapter 2 also deals with the question of which elements have made this theme so popular. Chapters 3,4, and 5 examine each of the three sets of variations in detail using the following format: theme, structure of each variation, harmony and key, rhythm and meter, tempo and dynamics, motivic development, grouping of variations, and technical problems. Chapter 6 summarizes the findings from this study and attempts to compare those elements among the three variations. Special attention is given to the application of the motivic cells, which are drawn from the original Paganini theme, in the development of succeeding variations. This study shows how these motivic cells contribute to the construction of new motives and melodies in each variation. Additionally, this study attempts to examine each composer's efforts in expanding variation procedure …

Low Leakage Asymmetric Stacked Sram Cell
Memory is an important part of any digital processing system. On-chip SRAM can be found in various levels of the memory hierarchy in a processor and occupies a considerable area of the chip. Leakage is one of the challenges which shrinking of technology has introduced and the leakage of SRAM constitutes a substantial part of the total leakage power of the chip due to its large area and the fact that many of the cells are idle without any access. In this thesis, we introduce asymmetric SRAM cells using stacked transistors which reduce the leakage up to 26% while increasing the delay of the cell by only 1.2% while reducing the read noise margin of the cell by only 15.7%. We also investigate an asymmetric cell configuration in which increases the delay by 33% while reduces the leakage up to 30% and reducing the read noise margin by only 1.2% compared to a regular SRAM cell.

An Introduction to Contemporary Characteristics in Twentieth-Century Piano Music for the Late-Intermediate Student: A Pedagogical Analysis of the Bagatelles, Opus 5 by Alexander Tcherepnin
Alexander Tcherepnin (1899-1977) was a Russian-born American composer, his musical style represents the modern and diverse features of much twentieth-century piano music. The purpose of this research is to conduct a comprehensive pedagogical analysis of Alexander Tcherepnin's Bagatelles, Op. 5 with the goal of introducing contemporary characteristics in twentieth-century piano music for the late-intermediate student. Chapter 2 contains overall biographical information regarding Alexander Tcherepnin and a discussion of the general compositional style of his piano works. Chapter 3 analyzes the Bagatelles, Op. 5 from the perspective of musical challenges concerning the contemporary characteristics, including contemporary harmony: interval of seconds, non-tertian chords, special use of the seventh chords, and ninth chords; contemporary rhythm and meter: shifted accents, asymmetric meter, meter change, and ostinato; modal melodic resources and tonalities; and other special tonalities. Chapter 4 has suggestions on fingering, pedaling, articulation, tone, dynamics and phrasing, and practicing procedures for individual technical difficulties. Studying the Bagatelles, Op. 5 provides a transition for the student from learning standard repertoire of the eighteenth and the nineteenth century, to contemporary repertoire through the combination of Russian compositional traditions with twentieth century repertory.

An Analysis of the Characteristics of Female Juvenile Offenders as Predictors of Resocialization or Recidivism.
Because there has been a paucity of research on the educational needs of females with academic, behavioral, and emotional problems involved with the juvenile justice system, this study has been an attempt to classify and compare specific characteristics of this population. In particular, it examined their demographics, disability prevalence rates, along with academic, behavioral, and emotional functioning levels, in order to further understand their relationship to the resocialization or recidivism of the different groups of female juveniles incarcerated in the state of Texas, and contribute to the research for further developing successful prevention and intervention programs. Various demographic factors of the female juveniles in this study were examined: (a) offender type, (b) county of commitment, (c) race/ethnicity, (d) age at first referral, and (e) English language proficiency. Prevalence rates of special education disabilities were determined. Academic functioning was measured by (a) IQ; (b) last school grade completed; (c) Test of Adult Basic Education (TABE) reading gain score; and (d) TABE math gain score. Behavioral functioning was indicated through (a) offense history, (b) documented behavior incidents, and (c) total risk score. Emotional functioning included DSM-IV diagnoses and treatment needs. Due to the design of the research being a descriptive exploration, the …

Space in Space: Privacy Needs for Long-Duration Spaceflight
Space exploration is a uniquely human activity. As humans continue to push the limits of exploring the unknown, they have sought knowledge supporting the sustenance of life in outer space. New technologies, advancements in medicine, and rethinking what it means to be a “community” will need to emerge to support life among the stars. Crews traveling beyond the Moon will rely on the development of new technologies to support the technological aspects of their missions as well as their quality of life while away from Earth. Likewise, through advancements in medicine, scientists will need to address remaining questions regarding the effects of long-duration spaceflight on the human body and crew performance. Space explorers must learn to utilize these new technologies and medical advancements while learning to adapt to their new environment in space and as a space community. It is important that researchers address these issues so that human survival beyond Earth is not only achievable but so that life among the stars is worth living and sustaining. This thesis addressed these issues in an attempt to extend the trajectory of space exploration to new horizons.

Determination of Habitat Preferences of Pronghorn (Antilocapra americana) on the Rolling Plains of Texas Using GIS and Remote Sensing
The Rocker b Ranch on the southern Rolling Plains has one of the last sizeable populations of pronghorn (Antilocapra americana) in Texas. To investigate habitat utilization on the ranch, pronghorn were fitted with GPS/VHF collars and were released into pastures surrounded by a variety of fences to determine how fence types affected habitat selection. Habitat parameters chosen for analysis were vegetation, elevation, slope, aspect, and distances to water, roads, and oil wells. Results showed that pronghorn on the ranch crossed modified fencing significantly less than other types of fencing. Pronghorn selected for all habitat parameters to various degrees, with the most important being vegetation type. Habitat selection could be attributed to correspondence of vegetation type with other parameters or spatial arrangements of physical features of the landscape. Seasonal differences in habitat utilization were evident, and animals tended to move shorter distances at night than they did during daylight hours.
