Bipolar disorder is associated with significant social and occupational impairments, as well as increased risk for substance abuse and suicide. More research is needed to identify potential mechanisms associated with vulnerability to the disorder. Previous research has identified altered processing of emotional information in bipolar and bipolar-prone individuals, including attentional biases which appear to differ based on the current affective state of the individual. The current study applied a sensitive measure of attention (i.e., eye-tracking) to assess whether vulnerability to bipolar disorder, as indexed by hypomanic personality traits, would be correlated with biases in attention to emotional facial stimuli, independent of mood state. Hypomanic personality traits were hypothesized to be associated with greater attention to happy and angry faces, as indexed by faster initial orientation, more frequent gazes, and longer gaze duration for these stimuli. Participants completed self-report measures assessing current mood symptoms, positive and negative affect, and hypomanic personality traits. They then completed two tasks assessing attention for emotional faces. The first was an eye-tracking task, which measured latency to first fixation, total gaze duration and total number of gazes for each emotional face category. The second was a spatial cueing task which assessed both attentional engagement with emotional …

Titanium dioxide nanoparticles (TiO2-NP) are one of the most abundantly utilized nanomaterials in the world. Studies have demonstrated the mechanism of acute toxicity in TiO2-NP to be the production of reactive oxygen species (ROS) leading to oxidative stress and mortality in exposed organisms. It has also been demonstrated that the anatase crystalline conformation is capable of catalyzing the cleavage of water molecules to further increase the concentration of ROS in the presence of ultraviolet radiation. This photoenhanced toxicity significantly lowers the toxicity threshold of TiO2-NP to environmentally relevant concentrations (ppb). The goal of this study was to determine whether dietary uptake and accumulation of TiO2-NP in the aquatic filter feeder Daphnia magna resulted in photoenhanced toxicity. D. magna and S. caprincornatum were exposed to aqueous solutions of 20ppm and 200ppm TiO2-NP for 24hrs and then transferred to clean moderately hard water. Samples were taken at various time points, dried, and TiO2 quantified using ICP-MS. Toxicity assays were run on D. magna using three TiO2-NP (20ppm, 200ppm) exposure protocols and two ultraviolet radiation treatments. The first exposure group was exposed to aqueous solutions of TiO2-NP for the duration of the test. The second exposure group was exposed to TiO2-NP for an …

Pat Tillman—an Arizona Cardinals player who sacrificed everything to serve his country but died in Afghanistan—was initially touted as a true American hero who was killed by enemy fire. In reality, however, the Tillman narrative was based on nothing but military propaganda. This research focused on how mainstream U.S. newspapers used news frames, overall story tone, and news sources before and after the official acknowledgement of the true cause of Tillman's death as fratricide. As hypothesized from C. Wright Mills' "lesser institutions," Antonio Gramsci's hegemony, and Edward S. Herman and Noam Chomsky's propaganda model, the newspapers generally decreased both direct and indirect references to news frames involving "lesser institutions" (e.g., NFL, Arizona State University) and ideological values (e.g., heroism, patriotism) after the revelation, but they were not critical of the Iraq/Afghanistan wars or the Bush administration at all. In addition, they increased their dependence on official sources and decreased family and friend sources after his cause of death was changed. The results as a whole indicate that in the Tillman saga, the revelation of his true cause of death introduced a significant disruption to the propaganda information system, causing news frames to decrease, but the third filter of the propaganda …

Ultimate is the fastest growing field sport in America. Created in 1968, forty-five years later the sport was still on the periphery of the mainstream but reached new heights in 2013 – two professional leagues, over 800 college teams and a broadcasting deal with ESPN – and the discussions throughout the sports’ history have never been as relevant. Self-officiation and the Spirit of the Game are the main tenets that make up the ethos of the sport and its community. These unique aspects differentiate Ultimate’s predominate culture from that of mainstream sports culture. This study shows the countercultural ties and survival of the ethos during the adolescent period of Ultimate’s evolution (1987-2010). It examines the progression of the community’s established grassroots culture and the governing body of the sport alongside the influx of young players with mainstream sports attitudes who bolstered certain organizers’ attempts to alter Ultimate in the hopes of gaining “legitimacy” through adding third-party officials, commercialization and corporate sponsorship.

The purpose of this research study is to analyze mental health related content on the three network affiliated stations in Las Vegas, Nevada. Online web stories from broadcast stations are analyzed in terms of the content and tone. These areas of analysis relate directly to the mass communication theories agenda setting and framing. Historically, mental health news reports have included content and tone that together can potentially create and further stigmatizing sentiments about those with mental illnesses. This study utilizes a chi square test to determine if a relationship exists between the three network affiliated stations, four a priori coded mental health content categories, and a rating of the overall tone using a value dimensions scale. Supplemental analyses include frequency evaluations of what has been called “people-first” versus “non-people first” language. By analyzing mental health related content at these three stations in the Las Vegas market this study aims to add heuristic value to the study of mental health reporting in broadcast news. This study will allow for additional research to further test relationships between stations, content, and tone in the Las Vegas and other news markets. Ultimately, this study provides analysis and discussion of the important role of agenda …

Overcapacity is a self-reflexive, personal journey film that explores the filmmaker's exploration of his lifelong problem with obesity and health. The film follows his progress as he discusses his weight problem with his partner and parents as well as works with a personal trainer and doctor in an effort to affect a lifestyle change while also confronting issues that have led to and perpetuate his current health situation.

This study explored attributes of a Facebook brand page (FBP). Seven variables were derived from the framework and applied to FBPs. The goals of this research were to discover which attributes contribute to a successful FBP, determine which attributes increase purchase intentions, and help marketers determine where to focus their efforts. A total of 421 surveys were gathered from men and women ages 18 and older. The methods of this research included factor analysis and multiple regression analysis. Results yielded two loading factors for the trustworthiness variable and supported hypotheses of trustworthiness increasing purchase intentions. It was also discovered that participation positively influences purchase intentions. It is advised that information content be monitored to avoid information overload.

A foreign country's positive or negative image in the U.S. media can influence public attitudes toward that country. The way U.S. media covers sex crimes from countries like India and Pakistan has a direct effect on the global image of these countries. This qualitative content analysis examined the coverage of two rape victims, Jyoti Singh Pandey and Mukhtar Mai in two mainstream U.S. newspapers, the New York Times and the Washington Post. Frames identified in the study include cultural differences, nationality and male patriarchy. The results revealed that while U.S. media was sensitive to both victims, Indian culture was portrayed in a favorable light than Pakistani culture. This study recommends that reporters and newsrooms need to be sensitive in reporting foreign cultures and refrain from perpetuating cultural stereotypes through reporting. The study also recommends developing training and understanding methodology when covering sex crimes so that journalists are aware of the rape myths and narratives that trap them into unfair coverage.

The purpose of this study was to provide a description of teacher perceptions concerning behavioral and physiological vocal issues among current gender groupings in sixth-grade choir classrooms through the collection of survey research data. Participants selected for this study consisted of registered Dallas-Fort Worth metropolitan area choral directors of the Texas Music Educators Association. Results of the study indicated that more girls were enrolled in sixth-grade choir than boys and that mixed choirs were more common than gender-specific choirs in sixth grade. Results also indicated that teachers perceived evidence of early voice change among both sixth grade boys and girls, and that there was a difference in behavior as students showed signs of puberty.

By engaging in collaborative arts-based and arts-informed narrative inquiry with my six-year-old daughter, we explored self-guided materials in art museums in the North Texas area. Though the field of art museum education is becoming increasingly participatory, most academic research related to self-guided materials has fallen short of exploring visitors' experiences with these materials. Furthermore, the perspectives of children have been long overlooked in academic and, at times, institutional research about family experiences in museums. Over the course of nine months, my daughter and I visited art museums and engaged with their self-guided materials, ranging from audio tours to interactive galleries. During this time we created collaborative works of art based on our experiences, which acted as both data collection and analysis in preparation for writing narratives. Our narrative explorations allowed us each to better understand our collective experiences. Though this research specifically targets self-guided materials in art museums, any educator interested in intergenerational or collaborative family learning may find both our methodologies and our conclusions to be helpful in better understanding how narratives are essential to this type of learning.

This thesis discusses the decline of the Venetian nobility, the collapse of the Venetian economy, and the political results of the surrender of the Venetian Republic to Napoleon Bonaparte in 1797. Topics include the formation of Venice, Venetian domination of trade, the class system in Venice prior to 1797, the collapse of the aristocracy, feudalism in Venice, Venice’s presence in the Adriatic and Aegean seas, and the rise of the middle class within the provisional democratic government. Very few historians have attempted to research the provisional democracy of Venice and how the political and class structure of Venice changed as a result of the collapse of the Republic in 1797. Using primary sources, including government documents and contemporary histories, one can see how the once dominant noble class slowly fell victim to economic ruin and finally lost their role in the political leadership of Venice all together. During this same period, the middle class went from only holding secretarial jobs within the government, to leaders of a modern democratic movement. On top of primary research, several secondary sources helped in explaining the exclusivity of the noble class and their journey from economic dominance to economic ruin and the administrative consequences …

The current study examined relationships among acculturation, parent-child relationship quality, and selected wellbeing indicators (health-related quality of life, life satisfaction, anxiety, depression, and stress) among a group of young adults from immigrant families of Asian and Hispanic descent. The first goal of the current study was to replicate previous research demonstrating a mixed relationship between acculturation and the wellbeing indicators. The second was to explain this relationship by testing for a moderation effect of parental care on the acculturation-wellbeing relationship. An examination of differences between members of the two ethnic groups on all measured variables served an exploratory purpose. Participants included 204 participants of Asian (N =80) and Hispanic (N = 124) descent who came from an immigrant family, or a family in which at least one parent was born outside of the U.S. Eligible respondents were also current students at the University of the North Texas who fell within the age range of 18-24, and the data for the current study was selected from a larger dataset (N = 1064). Results indicated that higher acculturation levels had a positive effect on each wellbeing indicator. Father Care and Mother Care were found to be significantly positively correlated with most outcome …

This study seeks to understand the development of early American ideas of race, religion, and gender as reflected in Indian and Barbary captivity narratives (tales of individuals taken captive by privateers in North Africa) and in plays that take American captives as their subject. Writers of both Indian and Barbary captivity narratives used racial and religious language – references to Indians and North Africans as demonic, physically monstrous, and animal – simultaneously to delineate Native American and North African otherness. The narrative writers reserved particular scorn for the figure of the Renegade – the willful cultural convert who chose to live among the Native Americans or adopt Islam and live among his North African captors. The narratives, too, reflect Early American gendered norms by defining the role of men as heads of household and women’s protectors, and by defining women by their status as dutiful wives and mothers. Furthermore, the narratives carefully treat the figure of the female captive with particular care – resisting implications of captive rape, even while describing graphic scenes of physical torture, and denying the possibility of willful transcultural sexual relationships.

Since the passing of No Child Left Behind Act in 2001, the United States' secondary education system has undergone significant changes. In this study, I discuss the ways in which the law has encouraged the normalization of standardized testing and aim to answer two primary research questions. RQ1: What do college students and their instructors identify as the key challenges that arise as students educated under NCLB begin college coursework, and how does each group address these challenges? RQ2: What strategies do the actors and spect-actors in a Forum Theatre production arrive at for addressing the challenges faced by college instructors and their students who have completed their secondary education under No Child Left Behind? To answer the initial research question, I conducted focus group interviews with instructors and students at the University of North Texas to understand the challenges each faces in the classroom. To answer the second research question, I compiled narratives from the focus group interviews along with other materials into a performance script that concluded with scenarios based in Augusto Boal's Forum Theatre techniques. In live performance events audience members rehearsed strategies for addressing the challenges that instructors and students face in classrooms through performance. Following …

The F-4 Phantom II was the United States' primary air superiority fighter aircraft during the Vietnam War. This airplane epitomized American airpower doctrine during the early Cold War, which diminished the role of air-to-air combat and the air superiority mission. As a result, the F-4 struggled against the Soviet MiG fighters used by the North Vietnamese Air Force. By the end of the Rolling Thunder bombing campaign in 1968, the Phantom traded kills with MiGs at a nearly one-to-one ratio, the worst air combat performance in American history. The aircraft also regularly failed to protect American bombing formations from MiG attacks. A bombing halt from 1968 to 1972 provided a chance for American planners to evaluate their performance and make changes. The Navy began training pilots specifically for air combat, creating the Navy Fighter Weapons School known as "Top Gun" for this purpose. The Air Force instead focused on technological innovation and upgrades to their equipment. The resumption of bombing and air combat in the 1972 Linebacker campaigns proved that the Navy's training practices were effective, while the Air Force's technology changes were not, with kill ratios becoming worse. However, the last three months of the campaign introduced an American …

This study examines orthographic variation in synchronous computer-mediated French discourse. All nontraditional variations of selected frequently occuring items are quantified in order to provide an etic (i.e., from an external perspective) analysis. The primary variable of interest is age since this study focuses on providing a comparison of chat participants in their twenties versus those in their fifties. The widespread claim is that younger people communicate using more informal and/or nontraditional forms than older people; however, the results of the present study suggest that this is not always the case. The main finding of the present study is that the twentysomethings and the fiftysomethings produce the nontraditional orthography in a similar fashion in 52.2% of the terms, and in a non-similar fashion in 47.8% of the terms. Following the presentation and discussion of the results, directions for future research are provided.

Heart burial is a funerary practice that has been performed since the early medieval period. However, relatively little scholarship has been published on it in English. Heart burial began as a pragmatic way to preserve a body, but it became a meaningful tradition in Western Europe during the medieval and early modern periods. In an anthropological context, the ritual served the needs of elites and the societies they governed. Elites used heart burial not only to preserve their bodies, but to express devotion, stabilize the social order and advocate legitimacy, and even gain heaven. Heart burial assisted in the elite Christian, his or her family, and society pass through the liminal period of death. Over the centuries, heart burial evolved to remain relevant. The practice is extant to the present day, though the motivations behind it are very different from those of the medieval and early modern periods.
