Newspaper Ownership Structure and the Quality of Local Political News Coverage

Newspaper Ownership Structure and the Quality of Local Political News Coverage

Date: May 2012
Creator: Clark, Karla Christine Marie
Description: This research sought to ascertain how newspaper ownership structures influence the quality of local political news coverage. More specifically, do independently owned newspapers tend to produce larger quantities of quality local political reporting than do corporately owned and publicly traded newspapers? In the thesis, I develop an understanding of "quality" news coverage as being coverage that is thematic, or providing interpretive analysis and supplying contextual information. Additionally, I tackle the question of quality news coverage from three angles: whether or not independently owned newspapers provide more quality local political news stories per edition than corporately owned papers; whether or not the percentage of quality local political news stories of total political news stories within an edition is higher for independently owned or corporately owned newspapers; and whether or not the percentage of total political news stories of total news stories is higher for independently owned or corporately owned newspapers.

Effects of Layer Double Hydroxide Nanoclays on the Toxicity of Copper to Daphnia Magna

Effects of Layer Double Hydroxide Nanoclays on the Toxicity of Copper to Daphnia Magna

Date: May 2012
Creator: Blake, Deanne Renee
Description: Nanoparticles may affect secondary pollutants such as copper. Layer Double Hydroxides (LDH) are synthetically produced nanoparticles that adsorb copper via cation exchange. Pretreatment of copper test solutions with LDH nanoparticles followed by filtration removal of LDH nanoparticles demonstrated the smallest LDH aggregates removed the most copper toxicity. This was due to increased surface area for cation exchange relative to larger particle aggregates. Co-exposure tests of copper chloride and clay were run to determine if smaller clay particles increased copper uptake by D. magna. Coexposure treatments had lower LC50 values compared to the filtration tests, likely as a result of additive toxicity. LDH nanoclays do reduce copper toxicity in Daphnia magna and may serve as a remediation tool.

General Satisfaction of Students in 100% Online Courses in the Department of Learning Technologies at the University of North Texas

General Satisfaction of Students in 100% Online Courses in the Department of Learning Technologies at the University of North Texas

Date: May 2012
Creator: Ahn, Byungmun
Description: 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 ...

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal

Date: May 2012
Creator: Gates, Michael S.
Description: The 2010 National HIV/AIDS Strategy outlined three important goals for managing the current HIV pandemic in the U.S.: (1) reduce the number of people who become infected with HIV; (2) improve access to health care and health-related outcomes for people living with HIV/AIDS (PLH/A); and (3) reduce HIV-related health disparities. Each of these goals tacitly depends upon reducing HIV-related stigma, and this study examined how HIV+ individuals evaluate coping efforts to overcome stigma’s impact on quality of life (QOL). a structural regression model was developed to instantiate the reappraisal process described by Lazarus and Folkman’s transactional theory of stress and coping, and this model indicated that maladaptive coping fully mediated the relationship between dispositional forgiveness and perceived stigma, which supports the prediction that coping efficacy is related to stress reduction. Additionally, maladaptive coping fully mediated the relationship between dispositional forgiveness and QOL, supporting the contention that forgiveness is a critical aspect to the evaluative process that influences how PLH/A cope with stigma. Lastly, the model showed that when PLH/A engaged in maladaptive coping to mitigate stress-related stigma, these individuals experienced increased stigmatization and reported significantly lower levels of health-related QOL. in contrast, PLH/A that reported higher levels of dispositional forgiveness ...

Rapid Prototyping and Design of a Fast Random Number Generator

Rapid Prototyping and Design of a Fast Random Number Generator

Date: December 2011
Creator: Franco, Juan
Description: Information in the form of online multimedia, bank accounts, or password usage for diverse applications needs some form of security. the core feature of many security systems is the generation of true random or pseudorandom numbers. Hence reliable generators of such numbers are indispensable. the fundamental hurdle is that digital computers cannot generate truly random numbers because the states and transitions of digital systems are well understood and predictable. Nothing in a digital computer happens truly randomly. Digital computers are sequential machines that perform a current state and move to the next state in a deterministic fashion. to generate any secure hash or encrypted word a random number is needed. But since computers are not random, random sequences are commonly used. Random sequences are algorithms that generate a pattern of values that appear to be random but after some time start repeating. This thesis implements a digital random number generator using MATLAB, FGPA prototyping, and custom silicon design. This random number generator is able to use a truly random CMOS source to generate the random number. Statistical benchmarks are used to test the results and to show that the design works. Thus the proposed random number generator will be useful ...

A Driver, Vehicle and Road Safety System Using Smartphones

A Driver, Vehicle and Road Safety System Using Smartphones

Access: Use of this item is restricted to the UNT Community.
Date: May 2012
Creator: Gozick, Brandon
Description: As vehicle manufacturers continue to increase their emphasis on safety with advanced driver assistance systems (ADAS), I propose a ubiquitous device that is able to analyze and advise on safety conditions. Mobile smartphones are increasing in popularity among younger generations with an estimated 64% of 25-34 year olds already using one in their daily lives. with over 10 million car accidents reported in the United States each year, car manufacturers have shifted their focus of a passive approach (airbags) to more active by adding features associated with ADAS (lane departure warnings). However, vehicles manufactured with these sensors are not economically priced while older vehicles might only have passive safety features. Given its accessibility and portability, I target a mobile smartphone as a device to compliment ADAS that can bring a driver assist to any vehicle without regards for any on-vehicle communication system requirements. I use the 3-axis accelerometer of multiple Android based smartphone to record and analyze various safety factors which can influence a driver while operating a vehicle. These influences with respect to the driver, vehicle and road are lane change maneuvers, vehicular comfort and road conditions. Each factor could potentially be hazardous to the health of the driver, ...

Early College High School: Hispanic Students’ Perceptions and Experiences From a Texas Campus

Early College High School: Hispanic Students’ Perceptions and Experiences From a Texas Campus

Date: May 2012
Creator: Brenner, Rose K.
Description: Early college high school (ECHS) is a dual enrollment program that allows high school students to earn college credits while in high school. ECHS was developed with the intention of attracting students to pursue a 4-year college degree, especially students who might not attend college without intervention. The program targets students from low-income families, students who have low academic achievement, and students from minority groups including Hispanics, African Americans, and Native Americans. The purpose of this study was to explore the perceptions and opinions of Hispanic students about their experiences in an ECHS, and to better understand how their ECHS experiences affected motivation to engage in academics. The expectancy theory and college-going culture provided the theoretical framework for this case study. Semi-structured interviews captured the experiences of the participants. The study focused on 10 Hispanic students, 5 seniors and 5 juniors, enrolled at an ECHS located on a community college campus in Texas. The study found that students with higher motivation to work at high school and college courses had several reasons for choosing to attend ECHS. The reasons included a chance to earn a high school diploma and associate’s degree simultaneously, free college tuition, and an accelerated program to ...

Continuity of Caste: Free People of Color in the Vieux Carré of New Orleans, 1804-1820

Continuity of Caste: Free People of Color in the Vieux Carré of New Orleans, 1804-1820

Date: May 2012
Creator: Foreman, Nicholas
Description: Because of its trademark racial diversity, historians have often presented New Orleans as a place transformed by incorporation into the American South following 1804. Assertions that a comparatively relaxed, racially ambiguous Spanish slaveholding regime was converted into a two-caste system of dedicated racial segregation by the advent of American assumption have been posited by scholars like Frank Tannenbaum, Gwendolyn Midlo Hall, and a host of others. Citing dependence on patronage, concubinage, and the decline in slave manumissions during the antebellum period, such studies have employed descriptions of the city’s prominent free people of color to suggest that the daily lives of non-whites in New Orleans experienced uniform restriction following 1804, and that the Crescent City’s transformation from Atlantic society with slaves to rigid slave society forced free people of color out of the heart of the city, known as the Vieux Carré, and into “black neighborhoods” on the margins of town. Despite the popularity of such generalized themes in the historiography, however, the extant sources housed in New Orleans’s valuable archival repositories can be used to support a vastly divergent narrative. By focusing on individual free people of color, or libres, rather than the non-white community as a whole, this ...

The Beauty of Nature As a Foundation for Environmental Ethics: China and the West

The Beauty of Nature As a Foundation for Environmental Ethics: China and the West

Date: May 2012
Creator: Gao, Shan
Description: My dissertation aims at constructing an environmental ethics theory based on environmental aesthetics in order to advocate and promote environmentally sustainable practices, policies, and lifestyles. I attempt to construct an integrated environmental aesthetics in order to inspire people’s feelings of love towards nature and motivate them to protect it. In order to achieve this goal, I first examine the philosophical understanding and aesthetic appreciation of nature from philosophical traditions of China, which have an impact on the general public’s attitude towards nature. in chapter one of my dissertation, I point out that nature is viewed as an organic system which is always in a self-generating process of production and reproduction of life. the metaphysical foundation for this perspective of nature is ch’i. Therefore the aesthetic appreciation of nature in China is also the aesthetic appreciation of ch’i. with regard to the concept of ch’i, I focus on the following three questions: (1) what are the objective and aesthetic features of ch’i? (2) How do the Chinese appreciate aesthetic features of ch’i? (3) Why the objective features of ch’i are regarded as the objects of aesthetic appreciation? I argue that the Chinese appreciate the aesthetic features of ch’i by using intellectual ...
