As a Chinese filmmaker, I feel obligated to reveal a true story about Chinese international students. Through my subjects and my stories, I am planning to express the messages that both adapting to a new culture and paying the financial cost of a foreign education have never been simple, but we will never give up our dreams. digital.library.unt.edu/ark:/67531/metadc500078/
Across Borders and Barlines: Chicana/o Literature, Jazz Improvisation, and Contrapuntal Solidarity
In this study, I examine Chicana/o writings and Black and Brown musical traditions as they entwine in urban centers and inform local visions of inclusion and models of social change. By analyzing literature and music from South Texas, Southern California, and Northeastern Michigan, I detail how the social particularities of each zone inform Chicana/o cultural productions rooted in the promise of empowerment and the possibility of cross-cultural solidarity. I assert that highlighting localized variations on these themes amplifies contrapuntal solidarities specific to each region, the relationship between different, locally conceived conceptions of Chicana/o identity, and the interplay between Brown and Black aesthetic practices in urban centers near national borders. Through literary critical and ethnomusicological frameworks, I engage the rhetorical patterns that link poetry, jazz improvisation, essays, musical playlists, and corridos to illumine a web of discourses helping to establish the idiosyncratic yet complimentary cultural mores that shape localized social imaginaries in the United States. digital.library.unt.edu/ark:/67531/metadc500033/
El Arquetipo Del Narco Mexicano En La Novela, El Cine, Y La Música
Various groups of Mexican culture have assigned to el narco archetypical characteristics of a heroic figure in the literary, visual, and auditory arts. As a result, today’s narcocultura has expanded its tentacles to a vast array of prominent industries, such as publishing companies, the silver screen, and recording studios. El narco is no longer seen by some sectors as the outlaw that stalks our society but, instead, as a hero who fights against a hegemonic faction to reclaim his sovereignty. This thesis unites interdisciplinary observations of the narco phenomena that Mexican culture has assigned to the iconic figure of el narco. The purpose of this work is to recreate the evolutionary development through a theoretical-literary analysis of this prototype in order to better understand Mexican society’s stance on this phenomenon. Octavio Paz’s theory of the Mexican psyche, Joseph Campbell’s theory of the hero’s journey, and an interdisciplinary focus will be employed to analyze this iconic figure. In this thesis, my aim is to investigate how an ultra-conservative Mexican society evolved into a consortium that upholds the narco’s indistinct behaviors and actions. What roles do first world governments and the Mexican state play to fortify, eradicate, or control the narco phenomenon? Finally, which is the most prudent strategy to coexist in a world alongside the narco? digital.library.unt.edu/ark:/67531/metadc500175/
Athletic Trainers and Sport Psychology: Knowledge, Experience and Attitudes
Certified athletic trainers (ATCs) play a unique role in sport environments as the primary medical staff available to athletes. Thus, ATCs are well positioned to oversee athletes’ physical and psychological well-being. Although sport psychologists (SPs) have been identified as a potential resource for ATCs, previous studies have reported a lack of collaboration between SPs and ATCs. This study aimed to (a) examine ATCs’ views regarding professional roles for both ATCs and SPs, (b) explore ATCs’ referral behaviors, (c) evaluate ATCs belief in the credibility of sport psychology across demographic (i.e., gender, age) and experiential variables (i.e., access to SPs), and (d) examine ATCs’ involvement in sport psychology. Four hundred ninety-six ATCs (265 men, 231 women) completed and returned the questionnaire. ATCs viewed assisting in the psychological recovery of athletes as the most acceptable professional role for fellow ATCs; aiding in the psychological recovery of injured athletes and teach mental skills were identified by ATCs as the most appropriate roles for SPs. In considering an athlete experiencing interpersonal difficulties (e.g., relationship problems), a mixed design ANOVA revealed a ATC sex by referral option interaction; female and male ATCs indicated they would likely refer the athlete to a counselor/therapist, followed by a SP, however, female ATCs reported a greater likelihood of referring to a counselor/therapist than male ATCs whereas male ATCs indicated a greater likelihood of referring to a SP. Further, ATCs’ regular access to SPs and completion of formal sport psychology coursework were identified as variables associated with greater belief in the credibility of sport psychology. These results suggest that access and previous experience with SPs remain significant variables associated with ATCs views about, and belief in, the work of SPs. Implications for sport psychology professionals and recommendations for future research are discussed. digital.library.unt.edu/ark:/67531/metadc500065/
Belfast: Perspectives of a City
This thesis film is an examination of my evolving perspectives and understanding of my Irish heritage as I travel to the city of Belfast, Northern Ireland. Through the course of a year and a half, I traveled to Belfast to explore the modern state of the sectarian conflicts between the Catholic and Protestant communities. Through the use of personal reflection, historical research, interviews with local residents, and on-location experiential learning, I began to learn not only about the modern state of Belfast and its economic and social climate, but also about the complexities of personal cultural identification and the concept of “truth” and “mutual guilt” when associated with acts of violence. With the use of the short documentary as the medium of choice, I am able to relay to audiences not only my own personal reflection of identity and history, but then allow them to reflect on their own perspectives as well, helping to create sincere moments of personal thought and reflections. digital.library.unt.edu/ark:/67531/metadc500003/
El Cine De Terror Español Como Espejo De La Cultura Española
Access: Use of this item is restricted to the UNT Community.
This study traces the history and culture of Spain as seen through the lens of the nation´s production of horror cinema. Starting from the boom of Spanish horror film in the early 1960s, the thesis compares and contrasts the political and social aspects of Spanish society throughout three distinct eras of the 20th century: 1962 – 1975 (the boom of Spanish horror film through the Franco dictatorship), 1975 – 1999 (the transition to democracy through the end of the 20th century) and 2000 – present (the 21st century). Movies as diverse as Gritos en la noche (1962, Jesús Franco), ¿Quién puede matar a un niño? (1976, Narciso Ibáñez Serrador) and Angustia (1987, Bigas Luna) are framed by culturally-related anectodes as well as correlations to their respective social environments. Special attention has been paid to the production and release of each film, especially in regards to censorship during the Franco dictatorship. The results show that Spanish horror cinema has acted as a true mirror to culture, society and politics in its native country throughout the 20th century and that this trend will likely extend in to the future. digital.library.unt.edu/ark:/67531/metadc500060/
Conjugal Rights in Flux in Medieval Poetry
This study explores how four medieval poems—the Junius manuscript’s Genesis B and Christ and Satan and Geoffrey Chaucer’s Troilus and Criseyde and The Parliament of Fowls—engage with medieval conjugal rights through their depictions of agentive female protagonists. Although many laws at this time sought to suppress the rights of women, especially those of wives’, both pre- and post-conquest poets illustrate women who act as subjects, exercising legal rights. Medieval canon and common law supported a certain amount of female agency in marriage but was not consistent in its understanding of what that was. By considering the shifts in law from Anglo-Saxon and fourteenth century England in relation to wives’ rights and female consent, my project asserts that the authors of Genesis B and Christ and Satan and the late-medieval poet Chaucer position their heroines to defend legislation that supports female agency in matters of marriage. The Anglo-Saxon authors do so by conceiving of Eve’s role in the Fall and harrowing of hell as similar to the legal role of a forespeca. Through Eve’s mimesis of Satan’s rhetoric, she is able to reveal an alternate way of conceiving of the law as merciful instead of legalistic. Chaucer also engages with a woman’s position in society under the law through his representation of Criseyde’s role in her courtship with Troilus in his epic romance, Troilus and Criseyde. Chaucer disrupts his audiences’ expectations by placing Criseyde as the more agentive party in her courtship with Troilus and shows that women might hope to the most authority in marriage by withholding their consent. In his last dream vision, The Parliament of Fowls, Chaucer engages again with the importance of female consent in marriage but takes his interrogation of conjugal rights a step further by imagining an alternate legal system through Nature, a female authority who gives equal consideration to all classes and genders. digital.library.unt.edu/ark:/67531/metadc500176/
Consumer Shopping Motivations with Facebook Retailers: Utilitarian Versus Hedonic
Retailers increasingly are connecting with consumers using social media. This two-way, networked communication method facilitates word-of-mouth that may ultimately impact retailer loyalty. The purpose of this study was to examine motivations of consumers’ purchase intention from apparel Facebook retailers, and the relationship between purchase intention and loyalty. Consumer motivations were examined in terms of the utilitarian values of cost, convenience, and information and the hedonic values of experiential shopping, bargain perception, sociability, and curiosity. The relationship of purchase intention and loyalty also was investigated. The instrument was developed from existing scales drawn from literature. A consumer panel (N = 250) of Facebook users that connect to apparel retailers was used to collect data through an online Qualtrics survey. Statistical analysis included descriptive statistics of frequency and crosstab distributions, factor analysis, and regression analysis. Factor analysis resulted in four dimensions including convenience, information, experience, and bargains. All motivators were found to be significantly related to both purchase intention and loyalty for this consumer group. The variable with the strongest relationship to both purchase intention and loyalty was experience. Additionally, a strong relationship was found between purchase intention and loyalty. Lastly, practical business implications are reviewed, in addition to limitations of the study. digital.library.unt.edu/ark:/67531/metadc500067/
A Cross-cultural Textual Analysis of Western and South Korean Newspaper Coverage of North Korean Women Defectors and Victims of Human Trafficking
Trafficking women for sexual abuse has been a serious concern worldwide, particularly over the last two decades. The International Labour Organization (ILO) estimated that illicit profits of human trafficking may be as high as $32 billion. However, the international media community has scarcely focused on North Korean women defectors and victims of human trafficking, despite the severity of the issue. More than two million North Koreans, predominantly women, have crossed borders to enter China from starvation. Among those women migrants, about 80% to 90% of them were abducted by traffickers at the border between North Korea and China, and the traffickers sold them to the Chinese sex industry or Chinese men who are unable to find a woman as a wife or a sex slave.This cross-cultural textual analysis examined South Korean and Western (U.S. and British) newspaper coverage of North Korean women as victims of human trafficking to discover similarities and differences in those countries’ news frames. The analysis has shown that politics was a crucial factor in the coverage of the issue. However, by generally failing to report on the fundamental causes of the trafficking, such as inequality between genders, both Western and South Korean newspapers perpetuated hegemonic masculinity and failed to inform and educate people about the grave situations of North Korean women defectors and victims of human trafficking. This study recommends that in reporting the trafficking issues, journalists must be able to observe objectively, not within ideologies or frames provided by politicians. digital.library.unt.edu/ark:/67531/metadc500051/
A Curious Collection of Visitors: Travels to Early Modern Cabinets of Curiosity and Museums in England, 1660-1800
The idea of curiosity has evolved over time and is a major building-block in the foundation and expansion of museums and their precursors, cabinets of curiosity. These proto-museums began in Italy and spread throughout Europe in the sixteenth and seventeenth centuries. Cabinets of curiosity and museums transformed as visitors traveled to burgeoning collections across the Continent and England. Individuals visited curiosities for a variety of reasons. Some treated outings to collections as social events in which they could see others in their social circles and perhaps rise in social status if seen by the correct people. Others were merely curious and hoped to see rare, astonishing, monstrous, and beautiful objects. Scholars of the era often desired to discover new items and ideas, and discuss scientific and philosophical matters. The British Isles are removed from the main body of Europe, but still play a major role in the history of collecting. A number of private collectors and the eventual foundation of the British Museum contributed seminally to the ever-increasing realm of curiosities and historic, cultural, and scientific artifacts. The collectors and collections of Oxford and London and its surrounding areas, drew a diverse population of visitors to their doors. Individuals, both foreign and local, female and male, visitors and collectors in Early Modern England chose to actively participate in the formation of a collecting culture by gathering, visiting, discussing, writing about, and publishing on collections. digital.library.unt.edu/ark:/67531/metadc500088/
Daily-collected Sleep Diaries Compared to Weekly-collected Sleep Diaries Via Actigraph Concordance
Access: Use of this item is restricted to the UNT Community.
Both sleep diaries and actigraphy have been recommended to assess sleep in research and clinical settings. Investigators have traditionally used sleep diaries that were completed daily by participants and collected weekly but have recently begun using sleep diaries that are both completed and collected daily. No research had previously assessed the agreement between daily-collected sleep diaries and actigraph data over one week. Undergraduate students were randomly assigned to use daily- or weekly-collected sleep diaries. Sleep parameters obtained from these measures were compared to each other via concordance with concurrent actigraph data. It was hypothesized that daily-collected sleep diaries would have greater concordance with actigraphy than weekly-collected sleep diaries. Results indicated that daily-collected sleep diaries provided more reliable data than weekly-collected sleep diaries, but the differences were not statistically significant. Additional aims examined self-reported sleep diary adherence, the participation day number, and day of the week. There were trends for the Daily group to have better adherence. Overall concordance did not change based on the day number or day of the week. Both sleep diaries yield comparable sleep parameter data, suggesting that clinicians and researchers can use either method to estimate sleep parameters. digital.library.unt.edu/ark:/67531/metadc500117/
Dance: a Training Package Utilizing Videotaped Self-observation to Teach Parents to Enhance Social Interactions with Children At-risk for a Developmental Delay
Previous research has demonstrated the effectiveness of programs that include a videotaped self-observation component. The self-observation protocols, however, have not been clearly specified within programs that teach and report parents’ use of general teaching strategies. The current study investigates the effects of a training package with a self-observation component to teach parents to improve teaching interactions with their children at-risk for a developmental delay using an AB design replicated across participants. Data were collected across play interactions to assess the number of parent teaching episodes, child target responses, and various parent and child relationship qualities. Relationship quality measures included parent and child affect and engagement, parent directives, parent confidence and stress, and parent and child interest. The results of this study suggest that the training package was effective in that parents engaged in higher rates of teaching, their children engaged in more desired responding, and certain aspects of the parent-child interaction were enhanced. These results are discussed in terms of the effects on the parent-child teaching interaction and implications for future use of parent self-observation techniques. digital.library.unt.edu/ark:/67531/metadc500215/
Ddos Defense Against Botnets in the Mobile Cloud
Mobile phone advancements and ubiquitous internet connectivity are resulting in ever expanding possibilities in the application of smart phones. Users of mobile phones are now capable of hosting server applications from their personal devices. Whether providing services individually or in an ad hoc network setting the devices are currently not configured for defending against distributed denial of service (DDoS) attacks. These attacks, often launched from a botnet, have existed in the space of personal computing for decades but recently have begun showing up on mobile devices. Research is done first into the required steps to develop a potential botnet on the Android platform. This includes testing for the amount of malicious traffic an Android phone would be capable of generating for a DDoS attack. On the other end of the spectrum is the need of mobile devices running networked applications to develop security against DDoS attacks. For this mobile, phones are setup, with web servers running Apache to simulate users running internet connected applications for either local ad hoc networks or serving to the internet. Testing is done for the viability of using commonly available modules developed for Apache and intended for servers as well as finding baseline capabilities of mobiles to handle higher traffic volumes. Given the unique challenge of the limited resources a mobile phone can dedicate to Apache when compared to a dedicated hosting server a new method was needed. A proposed defense algorithm is developed for mitigating DDoS attacks against the mobile server that takes into account the limited resources available on the mobile device. The algorithm is tested against TCP socket flooding for effectiveness and shown to perform better than the common Apache module installations on a mobile device. digital.library.unt.edu/ark:/67531/metadc500027/
Design and Application of a New Planar Balun
The baluns are the key components in balanced circuits such balanced mixers, frequency multipliers, push–pull amplifiers, and antennas. Most of these applications have become more integrated which demands the baluns to be in compact size and low cost. In this thesis, a new approach about the design of planar balun is presented where the 4-port symmetrical network with one port terminated by open circuit is first analyzed by using even- and odd-mode excitations. With full design equations, the proposed balun presents perfect balanced output and good input matching and the measurement results make a good agreement with the simulations. Second, Yagi-Uda antenna is also introduced as an entry to fully understand the quasi-Yagi antenna. Both of the antennas have the same design requirements and present the radiation properties. The arrangement of the antenna’s elements and the end-fire radiation property of the antenna have been presented. Finally, the quasi-Yagi antenna is used as an application of the balun where the proposed balun is employed to feed a quasi-Yagi antenna. The antenna is working in the S-band radio frequency and achieves a measured 36% fractional bandwidth for return loss less than -10 dB. The antenna demonstrates a good agreement between its measurement and simulation results. The impact of the parasitic director on the antenna’s performance is also investigated. The gain and the frequency range of the antenna have been reduced due to the absence of this element. This reduction presents in simulation and measurement results with very close agreement. digital.library.unt.edu/ark:/67531/metadc500144/
Design of Tunable/reconfigurable and Compact Microwave Devices
With the rapid development of the modern technology, radio frequency and microwave systems are playing more and more important roles. Since the time the first microwave device was invented, they have been leading not only the military but also our daily life to a new era. In order to make the devices have more practical applications, more and more strict requirements have been imposed. For example, good adaptability, reduced cost and shrank size are highly required. In this thesis, three devices are designed based on this requirement. At first, a symmetric four-port microwave varactor based 90-degree directional coupler with tunable coupling ratios and reconfigurable responses is presented. The proposed coupler is designed based on the modified structure of a crossover, where varactors are loaded. Then, a novel reconfigurable 3-dB directional coupler is presented. Varactors and inductors are loaded to the device to realize the reconfigurable performance. By adjusting the voltage applied to the varactors, the proposed coupler can be reconfigured from a branch-line coupler (90-degree coupler) to a rat-race coupler (180 degree coupler) and vice versa. At last, two types (Type-I and Type-II) of microwave baluns with generalized structures are presented. Different from the conventional transmission-line-based baluns where λ/2 transmission lines or λ/4 coupled lines are used, the proposed baluns are constructed by transmission lines with arbitrary electrical lengths. digital.library.unt.edu/ark:/67531/metadc500093/
Development of a Cost Effective Wireless Sensor System for Indoor Air Quality Monitoring Applications
Poor air quality can greatly affect the public health. Research studies indicate that indoor air can be more polluted than the outdoor air. An indoor air quality monitoring system will help to create an awareness of the quality of air inside which will eventually help in improving it. The objective of this research is to develop a low cost wireless sensor system for indoor air quality monitoring. The major cost reduction of the system is achieved by using low priced sensors. Interface circuits had to be designed to make these sensors more accurate. The system is capable of measuring carbon dioxide, carbon monoxide, ozone, temperature, humidity and volatile organic compounds. The prototype sensor node modules were developed. The sensor nodes were the connected together by Zigbee network. The nodes were developed in such a way that it is compact in size and wireless connection of sensor nodes enable to collect air quality data from multiple locations simultaneously. The collected data was stored in a computer. We employed linear least-square approach for the calibration of each sensor to derive a conversion formula for converting the sensor readings to engineering units. The system was tested with different pollutants and data collected was compared with a professional grade monitoring system for analyzing its performance. The results indicated that the data from our system matched quite well with the professional grade monitoring system. digital.library.unt.edu/ark:/67531/metadc499988/
Development of High Gain Ultraviolet Photo Detectors Based on Zinc Oxide Nanowires
Semiconductor nanowires acts as an emerging class of materials with great potential for applications in future electronic devices. Small size, large surface to volume ratio and high carrier mobility of nanowires make them potentially useful for electronic applications with high integration density. In this thesis, the focus was on the growth of high quality ZnO nanowires, fabrication of field effect transistors and UV- photodetectros based on them. Intrinsic nanowire parameters such as carrier concentration, field effect mobility and resistivity were measured by configuring nanowires as field effect transistors. The main contribution of this thesis is the development of a high gain UV photodetector. A single ZnO nanowire functioning as a UV photodetector showed promising results with an extremely high spectral responsivity of 120 kA/W at wavelength of 370 nm. This corresponds to high photoconductive gain of 2150. To the best of our knowledge, this is the highest responsivity and gain reported so far, the previous values being responsivity=40 kA/W and gain=450. The enhanced photoconductive behavior is attributed to the presence of surface states that acts as hole traps which increase the life time of photogenerated electrons raising the photocurrent. This work provides the evidence of such solid states and preliminary results to modify the surface of ZnO nanowire is also produced. digital.library.unt.edu/ark:/67531/metadc500106/
Dual-band Microwave Device Design
This thesis presents a brief introduction to microwave components and technology. It also presents two novel dual-band designs, their analysis, topology, simulation and fabrication. In chapter 2, a novel dual-band bandpass filter using asymmetric stub-loaded stepped-impedance resonators (SLSIRs) operating at 1 and 2.6 GHz is shown. This type of design applies suitable arrangements to improve the filter’s performance. Then, in chapter 3, a novel dual-band balun (transforms unbalanced input signals to balanced output signals or vice versa) operating at 1.1 and 2 GHz with flexible frequency ratios is presented, which has more advantages in microwave applications. Then, conclusion and future works are discussed in chapter 4. digital.library.unt.edu/ark:/67531/metadc500173/
The Effect of Natural Gas Well Setback Distance on Drillable Land in the City of Denton, Texas
Access: Use of this item is restricted to the UNT Community.
Municipalities protect human health and environmental resources from impacts of urban natural gas drilling through setback distances; the regulation of distances between well sites and residences, freshwater wells, and other protected uses. Setback distances have increased over time, having the potential to alter the amount and geographical distribution of drillable land within a municipality, thereby having implications for future land use planning and increasing the potential for future incompatible land uses. This study geographically applies a range of setback distances to protected uses and freshwater wells in the city limits of Denton, Texas to investigate the effect on the amount of land remaining for future gas well development and production. Denton lies on the edge of a productive region of the Barnett Shale geological formation, coinciding with a large concentration of drillable land in the southwestern region of the study area. This region will have the greatest potential for impacts to future municipal development and land use planning as a result of future gas well development and higher setback standards. Given the relatively high acreage of drillable land in industrially zoned subcategory IC-G and the concern regarding gas well drilling in more populated areas, future drilling in IC-G, specifically in IC-G land cover classes mowed/grazed/agriculture and herbaceous, would have the least impact on residential uses and tree cover, as well as decreasing the potential for future incompatible land uses. digital.library.unt.edu/ark:/67531/metadc499998/
The Effects of a Mental Training Program on Tennis Players’ Service Form and Consistency
The current study investigated whether combining a ten-week imagery training and video modeling intervention would improve the consistency and form of tennis serves, and to determine if differences in intervention effectiveness were based on skill level of the players. Sixty-one high school tennis players (Mage = 15.44, SD = .98) were separated into four groups; a control group and an experimental group which received the mental training program. Univariate analyses of covariance controlling for possible pre-test differences, gender, and years of tennis experience and a chi-squared analysis for responders to treatment showed no significant differences for the experimental group. Thus, the ten-week imagery training and video modeling intervention used in this study appeared to not influence tennis service form and consistency. There is a need for longitudinal studies of mental training techniques to determine whether these practices are effective for athletes of different sports and competitive levels. digital.library.unt.edu/ark:/67531/metadc500084/
The Effects of Sucrose on Ethanol Consumption in Ethanol Naïve and Non-naïve Rats
Sucrose fading and intermittent access are two common procedures that induce alcohol consumption in rodents. Sucrose fading procedures involve exposing ethanol naïve rats to a mixture of ethanol and sucrose and gradually reducing the concentration of sugar. Intermittent access procedures involve providing rats with access to ethanol on alternating days. Given that rats will consume ethanol without sucrose, the role of sugar in the sucrose fading procedure is unclear. Rats must be ethanol naïve when they are exposed to treatment with sucrose fading, so there is no point of comparison to show that exposure to sugar in sucrose fading produces higher levels of drinking. There has yet to be any work that isolates the effects of sugar on the consumption of alcohol. The purpose of the present experiment was to examine the effects of sucrose on ethanol consumption in rats with different alcohol histories. Two groups of six rats were exposed to two successive sucrose fading procedures, 30 days apart and their drinking was measured 30 days after each one. One group was exposed to an intermittent access procedure to establish drinking prior to treatment with sucrose fading, the other was ethanol naïve. Following sucrose fading, all rats drank pharmacologically active doses of ethanol. For both groups consumption correlated with the concentration of sucrose and decreased in a step-wise manner as it was faded. For the ethanol experienced rats, consumption dropped below baseline levels as sucrose was faded and decreased further with the second exposure. In contrast, the ethanol-naïve rats did not decrease consumption from the first sucrose fading procedure to the second. Slight differences in peak force of responses were also observed. digital.library.unt.edu/ark:/67531/metadc500220/
Effects of Vegetation Structure and Canopy Exposure on Small-scale Variation in Atmospheric Deposition Inputs to a Mixed Conifer Forest in California
Data on rates of atmospheric deposition is limited in many montane ecosystems, where high spatial variability in meteorological, topographic, and vegetation factors contributes to elevated atmospheric inputs and to the creation of deposition hotspots. Addressing the ecological consequences of increasing deposition in these areas will require a better understanding of surface controls influencing atmospheric deposition rates at both large and small-scales. The overarching objective of this thesis research was to understand the influence of vegetation structure and canopy exposure on small-scale patterns of atmospheric sulfate, nitrate, and chloride deposition inputs to a conifer forest in the Santa Cruz Mountains, California. Throughfall ion fluxes (i.e., ions delivered in water that pass from the forest canopy to the forest floor), bulk deposition (i.e., primarily wet deposition), and rainfall data were collected during the rainy period from October 2012 to May 2013. Throughfall SO42-, Cl-, and NO3- fluxes were measured beneath eight clusters of Douglas fir (Pseudotsuga menziesii) trees (three trees per cluster) differing in tree size (i.e., diameter at breast height; DBH) and canopy exposure. In each cluster, a throughfall collector was placed 1-meter from the bole of an individual tree, for a total of 24 individual collectors. The position of each throughfall collector was recorded with a Trimble® GPS. In addition, tree height, tree diameter, and leaf area index, were measured for all trees. LiDAR data were obtained from GeoEarthScope’s Northern California Airborne LiDAR project and used to model the elevation (DEM), canopy surface height (DSM), tree height (CHM), slope, and curvature of the canopy surface across the entire study area. Over the rainy season, total throughfall flux of SO42--S, a conservative tracer of total deposition (wet + dry + fog), to Douglas fir clusters ranged from 1.44 - 3.84 kg S ha-1 wet season-1, while dry and fog deposition ranged from 0.13 -2.37 kg S ha-1 wet season-1. Total deposition to exposed mature tree clusters was 1.7-2.7 times higher than other clusters. Patterns of total Cl- fluxes (17.10 – 54.14 kg Cl- ha-1 wet season-1) resembled patterns of total SO42--S inputs. Overall, net throughfall fluxes (throughfall – bulk deposition) to Douglas fir trees clusters were more variable than total throughfall fluxes. Net SO42--S and Cl- fluxes to individual collectors increased with tree DBH and the convexity of the canopy surface. Compared to SO42--S and Cl- in throughfall, total NO3--N fluxes (0.17 - 4.03 kg N ha-1 wet season-1) were low and appeared to vary with small-scale changes in elevation. Geospatial technologies and remote sensing tools, such as LiDAR, are promising in the study of relationships between atmospheric deposition and topography (including vegetation), and in scaling-up estimates of atmospheric deposition to larger spatial scales. Understanding small-scale surface controls on atmospheric deposition has implications for different areas of research within geography, including modeling the spread of emerging infectious disease and assessing the effects of nitrogen cycling on native and invasive plant species composition. digital.library.unt.edu/ark:/67531/metadc500055/
An Exploratory Study of Restaurant Multi-unit Managers’ Development
Development is important to the initial phase of a new restaurant multi-unit manager (MUM), and appropriate training should be conducted in concert with acceptance of the position. The purpose of this study is to explore the need for individual training of restaurant MUMs in order to facilitate a smoother transition between executive level management positions. The exhaustive literature review aided in the creation of three research questions to be answered through the interpretation of collected interview data. Restaurant MUMs were invited to participate via LinkedIn, a social media network for professionals. Semi-structured interviews were conducted with 17 restaurant MUMs over a two-week period and then transcribed into Word documents and uploaded into ATLAS.ti for analysis. The use of tools within ATLAS.ti, such as network mapping and semantic layouts, allowed the researcher to interpret the correlation between codes and themes created and therefore, answer the research questions. Conventionally, managers have to leave their restaurants or area for many days in order to obtain the necessary training to be more effective in their positions. This study has concluded that while MUMs are aware of their tasks and responsibilities, they are not aware of training available in order to gain the skillset necessary to complete the tasks. Blanket training programs will not work for MUMs, they need training to be customized to such areas as new openings, wide-spread markets and the changing workforce. More courses in developing others need to be implemented so MUMs can learn the skills needed to properly develop their managers into leaders. digital.library.unt.edu/ark:/67531/metadc500197/
Factors Related to Meeting Physical Activity Guidelines in College Students: a Social Cognitive Perspective
Engaging in regular physical activity is important for maintaining and improving health. Unfortunately, most college students fail to meet the recommendations for both aerobic and muscle-strengthening physical activity guidelines (PAGs). Psychosocial factors described within the social cognitive theory are related to the acquisition and retention of physical activity behaviors. The purpose of this study was to examine the relations of gender, self-efficacy, outcome expectancies, and social support with college students meeting aerobic, muscle-strengthening and both PAGs. Participants (N = 396) completed online questionnaires assessing their physical activity behaviors, exercise self-efficacy, outcome expectancies, and social support. Self-reported physical activity was classified as meeting / not meeting PAGs. Using gender, exercise self-efficacy, outcome expectancies, and social support as predictors, separate logistic regressions were used to examine their relations with the three PAG classifications. Analyses revealed that being male and level of social support increased the odds of meeting muscle-strengthening PAGs, but students’ level of self-efficacy and outcome expectations increased the odds of meeting all three PAG classifications. These findings indicate that interventions designed to increase self-efficacy and outcome expectancy may be beneficial for increasing college students’ physical activity for meeting the PAGs. Promotion of muscle-strengthening activities targeted at young women is also warranted. digital.library.unt.edu/ark:/67531/metadc500163/
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. digital.library.unt.edu/ark:/67531/metadc500045/
Further Evaluation of Blocked Trials to Teach Intraverbal Conditional Discriminations: Effects of Criterion-level Probes
Individuals with autism often have deficient intraverbal repertoires. Previous research has found success in using a blocked trials procedure to facilitate discrimination training. A previous study (unpublished) from our laboratory extended this procedure to intraverbal training. The current study continued this line of research by exploring the outcomes of probing the criterion performance more frequently. Three children with autism, ages 7-13, participated. Eight question pairs were taught. One question was presented repeatedly until a specified number of consecutive correct responses occurred, then the other question was presented. Contingent on specific mastery criteria, the trial blocks were faded into smaller blocks until the questions were presented in quasi-random order. Between each step, a criterion probe was conducted to determine if further steps were necessary. The procedure has been successful for two of the three participants. Criterion probe performance showed that not all teaching steps were needed every time. The procedure may have facilitated acquisition over time, because the number of trials to mastery generally decreased over successive targets. digital.library.unt.edu/ark:/67531/metadc500030/
Geek As a Constructed Identity and a Crucial Component of Stem Persistence
The fields of science, technology, engineering and mathematics (STEM) have long been the bastions of the white male elite. Recently, academia has begun to recognize gender and ethnic disparities. In an effort to expand the recruitment pool for these STEM fields in college, various efforts have been employed nationally at the secondary level. In California, the latest of these efforts is referred to as Linked Learning, a pedagogy that combines college preparation with career preparation. The current study is investigating the connection between what has been referred to in current scholarship as "Geeking Out" with higher academic performance. The phenomenon of “Geeking Out” includes a variety of non-school related activities that range from participating in robotics competitions to a simple game of Dungeons & Dragons. The current project investigates the relationship between long term success in STEM fields and current informal behaviors of secondary students. This particular circumstance where Linked Learning happens to combine with "Geeking Out" is successful due to the associated inclusionary environment. Methods included a yearlong ethnographic study of the Center for Advanced Research and Technology, a Central Valley school with a diverse student body. Through participant observation and interviews, the main goal of this research is to examine the circumstances that influence the effectiveness found in the environment of the Center for Advanced Research and Technology. digital.library.unt.edu/ark:/67531/metadc500004/
Hip-hop’s Tanning of a Postmodern America: a Longitudinal Content Analysis of Paradoxical Juxtapositions of Oppositional Identities Within Us Rap Song Lyrics, 1980-2013
A longitudinal content analysis of top-chart hip-hop songs’ lyrics produced between 1980 and 2013 was conducted to investigate the degree and progression of the paradoxical juxtaposition, or postmodern hybridity, of oppositional modernist identities in terms of race/ethnicity, gender, sexual orientation, sexuality, and economic lifestyle, in addition to the longitudinal diversification of artist’s race and gender demographics. Demographically, the percentage of non-African-American artists increased as the percentage of African-American artists decreased. Additionally, the percentage of songs featuring either all male or all female artists decreased, while the percentage of collaboration between male and female artists increased over time. Although hybrid oppositional identities related to race/ethnicity and gender did not increase over time, those of sexual orientation, sexuality, and economic lifestyle increased over time. In addition, materialist identities were related to the hybridity of sexual orientation and sexuality, but not to that of gender and race/ethnicity. Overall, the research found increasing postmodern hybridity within the sexualization of hip-hop songs along with intensified materialism. digital.library.unt.edu/ark:/67531/metadc500206/
Homeless Abjection and the Uncanny “Place” of the National Imagination
This project examines the effects of the homeless body and the threat of homelessness on constructing a national imaginary that relies on the trope of locatability for recognition as a citizen-subject. The thesis argues that homelessness, the oft-figured specter of public space, functions as bodies that are “pushed out” as citizen-subjects due to their inability maintain both discursive and material location. I argue that figures of “home” rely on the ever-present threat of dislocation to maintain a privileged position as the location of the consuming citizen-subject. That is, the presence of the dislocated homeless body haunts the discursive and material construction of home and its inhabitants. Homeless then becomes the uncanny inverse of home, functioning as an abjection that reifies home “place” as an arbiter of recognition in a neoliberal national imaginary. The chapters proceed to examine what some consider homeless “homes,” focusing on the reduction of the homeless condition to a place of inhabitance, or the lack thereof. This attempt to locate the homeless body becomes a symptom of the desire for recognition as a placed body. The thesis ends on a note of political possibility, figuring the uncanny as a rupture that evacuates language of signification and opens up space for a form of recognition without an over-determined identity. digital.library.unt.edu/ark:/67531/metadc500028/
Identifying Opportunities for the Revitalization of Downtown Bloomsburg
American downtowns were once the place to see and be seen, but the introduction of the shopping mall in the late 1950s challenged this notion and gave the American consumer a different place to spend their time and money. The prevalence of shopping malls has slowly been declining across the country since the beginning of this century, leaving room in the American retail landscape for downtowns to reclaim their status as community and retail centers. Towns across the U.S. are turning to national and local organizations to assist them in revitalizing their downtown districts. Downtown Bloomsburg, Inc. (DBI), a non-profit organization located in the small town of Bloomsburg, Pennsylvania, has been working since 2006 to revitalize its town’s downtown and main street area. The unique findings presented here were derived from a four month long ethnographic study of downtown Bloomsburg merchants and shoppers and are meant to be used by DBI as a supplemental guide for further revitalization of the town. digital.library.unt.edu/ark:/67531/metadc500143/
An Implementation of Consensus Through Bluetooth Communication
This thesis provides an implementation of consensus of multi-agent networked systems. Consensus problem is an important issue of distributed computing and has various algorithms and applications in the field of electronical and computer science. The consensus requests all nodes of a network reach an agreement over a certain measurement. An algorithm of convergent consensus problem is implemented through a small network of Bluetooth communication in the thesis. The connections of the Bluetooth devices are wireless, and the device nodes of the network are driven by C++ software and Winsock API. The simulation results show that the implementation completes all the requirements of the distributed consensus algorithm. digital.library.unt.edu/ark:/67531/metadc500099/
Importance and Spatial Distribution of Phytophthora Ramorum Host Species in a Coast Redwood Forest
Phytophthora ramorum, an exotic forest pathogen known as ‘sudden oak death’ (SOD), has received considerable attention in recent years because of its effects on vegetation structure, composition, and fire disturbance regimes in western U.S. coastal forests. This research examines differences in the importance (e.g., density, dominance, and frequency) and distribution of five host species of P. ramorum–– Umbellularia californica (California bay laurel), Quercus agrifolia (coast live oak), Pseudotsuga menziesii (Douglas fir), Sequoia sempervirens (Coast redwood), and Arbutus menziesii (Madrone)––in Soquel, California. A stratified random sampling design was used to select 66 plots surrounding a managed forest edge in Soquel Demonstration State Forest. Vegetation measurements were conducted in summer 2013. In each plot, all trees ≥3 cm diameter at breast height (DBH) were identified to species, counted, and DBH, height, and canopy position measured. Leaf area index (LAI) of bay laurel was measured to quantify the amount of leaves available for pathogen dispersal with a LiCOR 2200 Plant Canopy Analyzer. In addition, morning (9:00 am) and afternoon (1:00 pm) photosynthetically active radiation (PAR) were quantified using a quantum light sensor. This paper examines the influence of environmental variables, including distance to edge, aspect, slope, and light availability on host species spatial patterns in Soquel, CA. Studying P. ramorum host pattern and importance among managed forest edges is critical for determining hotspots most susceptible to infection and spread, thus relevant for implementing control measures. digital.library.unt.edu/ark:/67531/metadc500168/
“The Inevitable: Withdrawn”
Access: Use of this item is restricted to the UNT Community.
The Inevitable: Withdrawn is a critical preface and collection of non-fiction writing: personal essay, lyric essay, fragments, and experimental forms. The work’s cohesive subject matter is the author’s European vacation directly following her divorce. Within the pieces, the author attempts to reconcile who she is when starting over and she begins to ask questions regarding the human condition: How do I learn to exhibit intimacy again, not just with romantic partners, but with also in a familial way with my father, and how does absence in these relationships affect my journey and how I write about it? How do I view, and remake myself, when finding my identity that was tied to another individual compromised? How does a body, both physical and belonging to me, and physical as text, take certain shapes to reflect my understanding? How do I define truth, and how do I interpret truth and authenticity in both experience and writing? How do I define and know the difference between belief and truth? And finally, how does narrative and language protect, or expose me? The Inevitable: Withdrawn considers debates regarding the definition of narrative in order to address a spectrum of non-fiction writing. The collection takes into consideration non-fiction conventions, form as functionality, philosophy, linguistics, cognitive psychology, prose and poetic theory, and the works of other notable writers. digital.library.unt.edu/ark:/67531/metadc500048/

The Intimacy of Death: Mahler’s Dramatic Narration in Kindertotenlieder
There has been relatively little scholarship to date on Mahler’s Kindertotenlieder. The writings about this song cycle that do exist primarily focus on the disparate nature of the poems and justify Kindertotenlieder as a cycle by highlighting various musical connections between the songs, such as keys and motivic continuity. Mahler, however, has unified the cycle in a much more complex and sophisticated way. His familiarity with Wagner’s music and methods, and his mastery of the human voice and orchestral voices allowed him to weave a dramatic grief-laden narrative. digital.library.unt.edu/ark:/67531/metadc500052/

Is Mindfulness Just Another Ego Depletion Exercise?
Given increasing interest in the therapeutic benefits of mindfulness, limitations of its treatment utility are frequently questioned. As such, the purpose of the study was to examine the effects of mindfulness on a subsequent self-control task in a sample of college students. A total of 67 participants were randomly assigned to one of three conditions: a control condition, an experimental mindfulness-only condition or a comparison expectancy-plus-mindfulness condition to investigate the utility of mindfulness practice when motivated by an outcome of increased self-control. Results did not indicate a difference in persistence on a difficult task between conditions, regardless of the manipulation. Conceptual and experimental limitations of current study’s findings, as well as future directions, are discussed. digital.library.unt.edu/ark:/67531/metadc499980/

En La Frontera Entre La Vida Y La Muerte: a Study of Women Reporters on the Us–mexico Border
In 2008 Ciudad Juarez erupted in a violent drug war. The Sinaloa Cartel and Juarez Cartel were in a battle for the lucrative drug route used to smuggle drugs into the United States, while President Felipe Calderon was waging his own war against all the drug cartels. During the height of the violence women journalists emerged on the front lines to tell the stories of Juarez. They risked their lives and dared to tell a story that others refused to. This mixed-method study examines frames used most often in the coverage of the drug war in Ciudad Juarez from 2008-2010. It examines The New York Times, the El Paso Times, and El Norte and also examines articles by the sex of the reporter. It also used in-depth interviews of both Mexican and American woman journalists who covered the drug war in Juarez to examine which themes developed about the reporter’s experiences in covering the drug war. digital.library.unt.edu/ark:/67531/metadc500186/
A Lego Mindstorms Nxt Based Test Bench for Multiagent Exploratory Systems and Distributed Network Partitioning
Networks of communicating agents require distributed algorithms for a variety of tasks in the field of network analysis and control. For applications such as swarms of autonomous vehicles, ad hoc and wireless sensor networks, and such military and civilian applications as exploring and patrolling a robust autonomous system that uses a distributed algorithm for self-partitioning can be significantly helpful. A single team of autonomous vehicles in a field may need to self-dissemble into multiple teams, conducive to completing multiple control tasks. Moreover, because communicating agents are subject to changes, namely, addition or failure of an agent or link, a distributed or decentralized algorithm is favorable over having a central agent. A framework to help with the study of self-partitioning of such multi agent systems that have most basic mobility model not only saves our time in conception but also gives us a cost effective prototype without negotiating the physical realization of the proposed idea. In this thesis I present my work on the implementation of a flexible and distributed stochastic partitioning algorithm on the Lego® Mindstorms’ NXT on a graphical programming platform using National Instruments’ LabVIEW™ forming a team of communicating agents via NXT-Bee radio module. We single out mobility, communication and self-partition as the core elements of the work. The goal is to randomly explore a precinct for reference sites. Agents who have discovered the reference sites announce their target acquisition to form a network formed based upon the distance of each agent with the other wherein the self-partitioning begins to find an optimal partition. Further, to illustrate the work, an experimental test-bench of five Lego NXT robots is presented. digital.library.unt.edu/ark:/67531/metadc500196/
Lipodystrophy, Body Image and Depression in Hiv Positive Black Women
Human immunodeficiency virus (HIV) seropositive men on highly active antiretroviral therapy treatment (HAART) who experience lipodystrophy syndrome (LD), a side effect of HAART, rate themselves as more depressed than those who did not experience LD(Crane et al., 2008). Furthermore, men who rated their LD symptoms as more severe also scored higher on depression measures than men who experienced less severe symptoms. It is unknown these findings can be generalized to other groups of HIV positive individuals. The current study seeks to fill this gap in the literature by exploring the associations between LD, body image, and depressive symptoms in an archival sample of HIV positive Black women. This study aims to describe the body changes associated with HAART in a Black female sample and explore the relationships between LD, body image, depression, and quality of life. Findings supported past research indicating a correlation between depression and poor body image but did not indicate that body image quality of life moderated the relationship between perceived body changes and depression. Results expanded on the literature by indicating that perceived body changes may be more distressing to Black women with HIV than objective changes. Lastly, findings suggested that Black women may have inaccurate perceptions of their own body changes. These findings are particularly informative for healthcare workers who treat HIV+ women. It is imperative that they consider clients’ self-report as well as clinical symptoms. digital.library.unt.edu/ark:/67531/metadc500152/
A Low-cost Wireless Sensor Network System Using Raspberry Pi and Arduino for Environmental Monitoring Applications
Sensors are used to convert physical quantity into numerical data. Various types of sensors can be coupled together to make a single node. A distributed array of these nodes can be deployed to collect environmental data by using appropriate sensors. Application of low powered short range radio transceivers as a communication medium between spatially distributed sensor nodes is known as wireless sensor network. In this thesis I build such a network by using Arduino, Raspberry Pi and XBee. My goal was to accomplish a prototype system so that the collected data can be stored and managed both from local and remote locations. The system was targeted for both indoor and outdoor environment. As a part of the development a controlling application was developed to manage the sensor nodes, wireless transmission, to collect and store data using a database management service. Raspberry Pi was used as base station and webserver. Few web based application was developed for configuring the network, real time monitoring, and database management. Whole system functions as a single entity. The use of open source hardware and software made it possible to keep the cost of the system low. The successful development of the system can be considered as a prototype which needs to be expanded for large scale environmental monitoring applications. digital.library.unt.edu/ark:/67531/metadc500182/
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. digital.library.unt.edu/ark:/67531/metadc500021/
Opening Doors for Excellent Maternal Health Services: Perceptions Regarding Maternal Health in Rural Tanzania
The worldwide maternal mortality rate is excessive. Developing countries such as Tanzania experience the highest maternal mortality rates. The continued exploration of issues to create ease of access for women to quality maternal health care is a significant concern. A central strategy for reducing maternal mortality is that every birth be attended by a skilled birth attendant, therefore special attention was placed on motivations and factors that might lead to an increased utilization of health facilities. This qualitative study assessed the perceptions of local population concerning maternal health services and their recommendations for improved quality of care. The study was conducted in the Karatu District of Tanzania and gathered data through 66 in-depth interviews with participants from 20 villages. The following components were identified as essential for perceived quality care: medical professionals that demonstrate a caring attitude and share information about procedures; a supportive and nurturing environment during labor and delivery; meaningful and informative maternal health education for the entire community; promotion of men’s involvement as an essential part of the system of maternal health; knowledgeable, skilled medical staff with supplies and equipment needed for a safe delivery. By providing these elements, the community will gain trust in health facilities and staff. The alignment the maternal health services offered to the perceived expectation of quality care will create an environment for increased attendance at health facilities by the local population. digital.library.unt.edu/ark:/67531/metadc500156/
Optimization of Superhydrophobic Surfaces to Maintain Continuous Dropwise Condensation
Access: Use of this item is restricted to the UNT Community.
In the past decade, the condensation on superhydrophobic surfaces has been investigated abundantly to achieve dropwise condensation. There is not a specific approach in choosing the size of the roughness of the superhydrophobic surfaces and it was mostly selected arbitrarily to investigate the behavior of condensates on these surfaces. In this research, we are optimizing the size of the roughness of the superhydrophobic surface in order to achieve dropwise condensation. By minimizing the resistances toward the transition of the tails of droplets from the cavities of the roughness to the top of the roughness, the size of the roughness is optimized. It is shown that by decreasing the size of the roughness of the superhydrophobic surface, the resistances toward the transition of the tails of droplets from Wenzel state to Cassie state decrease and consequently dropwise condensation becomes more likely. digital.library.unt.edu/ark:/67531/metadc500016/
Paralysis As “Spiritual Liberation” in Joyce’s Dubliners
In James Joyce criticism, and by implication Irish and modernist studies, the word paralysis has a very insular meaning. The word famously appears in the opening page of Dubliners, in “The Sisters,” which predated the collection’s 1914 publication by ten years, and in a letter to his publisher Grant Richards. The commonplace conception of the word is that it is a metaphor that emanates from the literal fact of the Reverend James Flynn’s physical condition the narrator recalls at the beginning of “The Sisters.” As a metaphor, paralysis has signified two immaterial, or spiritual, states: one individual or psychological and the other collective or social. The assumption is that as a collective and individual signifier, paralysis is the thing from which Ireland needs to be freed. Rather than relying on this received tradition of interpretation and assumptions about the term, I consider that paralysis is a two-sided term. I argue that paralysis is a problem and a solution and that sometimes what appears to be an escape from paralysis merely reinforces its negative manifestation. Paralysis cannot be avoided. Rather, it is something that should be engaged and used to redefine individual and social states. digital.library.unt.edu/ark:/67531/metadc500199/
Physiological and Psychological Effects of an Acute Stressor: Comparing Coping Strategies Among Very Physically Active and Less Active Adults
The purpose of this study was to examine whether physical activity status of healthy adult males (N = 59) while in a coping strategy condition (association, disassociation, or control) influences psychophysiological responses to an acute painful stimulus. Measures of pain tolerance, state anxiety, body awareness, and salivary cortisol were investigated. Results indicated no significant differences between physical activity groups for pain tolerance, stress responses (i.e., self-reported state anxiety and cortisol levels), or body awareness. Though, those who indicated using a disassociation coping technique during the exit interview tolerated the acute, surface pain longer. More research is required to further understand the effects of physical activity and coping strategies on pain perception and psychophysiological responses. digital.library.unt.edu/ark:/67531/metadc500119/
Playing Nice: the Limitations and Stereotypes Placed on Female Hero Representation in Video Games
This thesis provides an investigation of how gender stereotypes affect the narrative, mechanics, and experience of three different console based video games (Venetica, WET, and Velvet Assassin) with female protagonist. Each game is addressed within separate case study chapters and discusses how gender is integrated and intertwined with each narrative structure, image representation, and interactivity. Further analysis is provided in each case study as gender is addressed across several parts of each game, beginning with the female protagonist’s role as hero, her representation throughout the game (i.e. body image, attire, and weapons), and the game play experience. In conclusion, this thesis shows that the protagonist gender within a video game does affect the game in its entirety. More specifically, all three female heroines discussed in this thesis showcases stereotypes associated with the dominant sexual representation of female video game characters, as well as similar traditional feminine and masculine stereotypes associated with heroines in film and television. This provides for rather problematic representations of female heroes, alone with the games designed for them which are equally as stereotypical in their narrative, mechanics, and game play. digital.library.unt.edu/ark:/67531/metadc500096/
Product Management: the Decision Process
This thesis builds upon several theoretical ideas. The first of which is the anthropologists’ transition into the corporate context and the particular type of skills and value that someone with anthropological training can bring to operations management. As anthropology is relatively new and unfamiliar to corporations, anthropologists are often hired without explicit knowledge of how they will address organizational problems. Frequently, this incremental relationship building between the anthropologist and the organization leads to shifting project goals which come only after the anthropologist is able to reveal initial findings to someone who has the power to grant the anthropologist further access to employees and company information. This refocusing comes from a building of trust that is crucially important for the anthropologist’s ability to identify social issues, which is the anthropologist’s expertise. In order to develop the context of this project the following paragraphs will explain in more detail and expand into particular cases in which anthropologists have helped organizations to identify and manage social, organizational problems. As a relationship needs to be built between the anthropologist and the organization, here I argue that there needs to be continual relationship building between anthropological, design, and management theories to optimally solve organizational problems. digital.library.unt.edu/ark:/67531/metadc500133/
Racial/ethnic Differences in Hospital Utilization for Cardiovascular-related Events: Evidence of a Survival and Recovery Advantage for Latinos?
Evidence continues to demonstrate that racial/ethnic minority groups experience a disproportionate burden of disease and mortality in cardiovascular-related diseases (CVDs). However, emerging evidence suggests a health advantage for Latinos despite a high risk profile. The current study explored the hospital utilization trends of Latino and non-Latino patients and examined the possibility of an advantage for Latinos within the context of CVD-related events with retrospective data collected over a 12-month period from a local safety-net hospital. Contrary to my hypotheses, there was no advantage for in-hospital mortality, length of stay or re-admission in Latinos compared to non-Latinos; rather, Latinos hospitalized for a CVD-related event had a significantly longer length of stay and had greater odds for re-admission when compared to non-Latinos. Despite data suggesting a general health advantage, Latinos may experience a relative disparity within the context of hospital utilization for CVD-related events. Findings have implications for understanding the hospital utilization trends of Latinos following a CVD-related event and suggest a call for action to advance understanding of Latino cardiovascular health. digital.library.unt.edu/ark:/67531/metadc500102/
