Aesthetics in the Popular Culture
The purpose of this thesis is to consider three opposing statements regarding aesthetics in our popular culture. The first statement is that the youth of this age are demolishing the old standards of aesthetic taste and are creating a nonaesthetic; the second statement is that the youth are enlarging the vision and scope of the accepted standard of aesthetic and changing its direction; the thrid statement is that the creations of the youth in our popular culture of today are neither new nor nonaesthetic, but merely a continuation of aesthetics as they are accepted. One statement will be chosen as the most valid of the three.

The Aesthetics of Minimalist Music and a Schenkerian-Oriented Analysis of the First Movement "Opening" of Philip Glass' Glassworks
Philip Glass' Glassworks (1981) is a six-movement composition for two flutes, two soprano saxophones/clarinets, two tenor saxophones/bass clarinets, two French horns, violas, cellos, and the DX7 electric piano. Glassworks consists of six movements titled "Opening," "Floe," "Island," "Rubric," "Facades," and "Closing." This thesis covers the first movement "Opening." Repetition in musical minimalism confronts traditional prescriptive codes of tonal music and post-tonal music. While challenging the traditional codes, repetition in musical minimalism established new codes for listening to minimal music. This thesis explores the implications of these ideas.

The Affect of Mobile Performance Support Devices on Anxiety and Self-Efficacy of Hospital Float Staff
Floating describes the act of staff moving from one unit to another based on the needs of the patients in a hospital. Many staff who float to different units express negative feelings, including anxiety and lack in self-efficacy. However, floating is both an economical and efficient method to use staff across the hospital, especially with current staffing shortages in the United States. This study investigated how the use of mobile performance support devices may help reduce anxiety and increase self-efficacy for those staff who float to different units. with access to multiple resources available on the mobile device, Bandura's social learning theory and self-efficacy concept set the framework through modeling, observing, and imitating others in order to reproduce certain behaviors and tasks and believe in one's capability to perform. a quantitative study incorporating the retrospective pretest-posttest design was conducted using the population of float staff, including both nurses and respiratory therapists, from Children's Medical Center of Dallas. Both the State-Trait Anxiety Inventory and General Self-Efficacy Scale, along with a basic demographic tool, were used to explore anxiety and self-efficacy in relation to the usage of mobile performance support devices. Findings can be used to impact the negative feelings of staff …

After the Planes
The dissertation consists of a critical preface and a novel. The preface analyzes what it terms “polyvocal” novels, or novels employing multiple points of view, as well as “layered storytelling,” or layers of textuality within novels, such as stories within stories. Specifically, the first part of the preface discusses polyvocality in twenty-first century American novels, while the second part explores layered storytelling in novels responding to World War II or the terrorist attacks of 9/11. The preface analyzes the advantages and difficulties connected to these techniques, as well as their aptitude for reflecting the fractured, disconnected, and subjective nature of the narratives we construct to interpret traumatic experiences. It also acknowledges the necessity—despite its inherent limitations—of using language to engage with this fragmentation and cope with its challenges. The preface uses numerous novels as examples and case studies, and it also explores these concepts and techniques in relation to the process of writing the novel After the Planes. After the Planes depicts multiple generations of a family who utilize storytelling as a means to work through grief, hurt, misunderstanding, and loss—whether from interpersonal conflicts or from war. Against her father’s wishes, a young woman moves in with her nearly-unknown grandfather, …

Age/Cohort Differences in Aspects of the Self-System
Age/cohort differences in several aspects of the self-system were investigated utilizing a sentence completion paradigm. Eighty-eight adults over age sixty and one hundred eight adults under age forty served as subjects. Subjects were asked to complete 30 self-referent sentence stems which were pre-structured to elicit information from the self-system. Responses were subjected to a content analysis utilizing a coding system which contained concepts used by subjects in their self-representations. Contents were coded for dimensions conceptually related to Physical Health, Autonomy, Self-Evaluation, Depression, Spirituality, and Altruism. Frequencies of codings were counted and subjected to statistical analysis for performing age group comparisons.

Age-Dependent Effects Of Chronic GABAA Receptor Blockade In Barrel Cortex
GABAA receptor binding is transiently increased in rat whisker barrels during the second postnatal week, at a time when neurons in the developing rat cortex are vulnerable to excitotoxic effects. To test whether these GABAA receptors might serve to protect neurons from excessive excitatory input, polymer implants containing the GABAA receptor antagonist bicuculline were placed over barrel cortex for a 4-day period in young (postnatal days 8 - 12) and adult rats. In the cortex of young, but not adult rats, the chronic blockade of GABAA receptors resulted in substantial tissue loss and neuron loss. The greater loss of neurons in young rats supports the hypothesis that a high density of GABAA receptors protects neurons from excessive excitatory input during a sensitive period in development.

Age Friendly Cities: The Bureaucratic Responsiveness Effects on Age Friendly Policy Adoption
Challenging a long-held attachment to the medical model, this research develops a cultural model placing local governments at the center of policy making and refocusing policy attention on mobility, housing, the built environment and services. To examine the phenomenon of age friendly policy adoption by cities and the magnitude of adoption, a 21-question web-based survey was administered to a sample of 1,050 cities from the U.S. Census having a population over 10,000 and having at least 14% of their population aged 65 years and over. The goal of the questionnaire was to help identify what kind of policy objectives cities establish to facilitate the opportunity for older adults to live healthy and independent lives in their communities as they age. Multiple linear and ordinal regression models examined the likelihood of policy action by cities and provide evidence as to why some cities support more age friendly policy actions than others. Evidence illustrates theoretical advancement providing support for a cultural model of aging. The cultural model includes multiple factors including bureaucratic responsiveness reflected in the management values of the administration. Findings show variation in the integration of a cultural awareness of aging in the municipality's needs assessment, strategic goals, citizen engagement …

Agenda-Setting by Minority Political Groups: A Case Study of American Indian Tribes
This study tested theoretical propositions concerning agenda-setting by minority political groups in the United States to see if they had the scope to be applicable to American Indian tribes or if there were alternative explanations for how this group places its agenda items on the formal agenda and resolves them. Indian tribes were chosen as the case study because they are of significantly different legal and political status than other minority groups upon which much of the previous research has been done. The study showed that many of the theoretical propositions regarding agenda-setting by minority groups were explanatory for agenda-setting by Indian tribes. The analyses seemed to demonstrate that Indian tribes use a closed policy subsystem to place tribal agenda items on the formal agenda. The analyses demonstrated that most tribal agenda items resolved by Congress involve no major policy changes but rather incremental changes in existing policies. The analyses also demonstrated that most federal court decisions involving Indian tribes have no broad impact or significance to all Indian tribes. The analyses showed that both Congress and the federal courts significantly influence the tribal agenda but the relationship between the courts and Congress in agenda-setting in this area of policy …

Aggression and Social Interest in Behavior Disordered Students
This study investigated whether behavior disordered children would decrease aggressive behavior if their social interest were developed. Three hypotheses that were tested predicted that there would be a significant difference between the control group and the experimental group on adjusted mean scores on aggressive behavior on post test scores. The measuring instruments used were the Child Behavior Checklist Parent Report Form, the Child Behavior Checklist Teacher Report Form, and the Child Behavior Checklist Director Observation Form. It was also predicted that there would be a significant difference between the control group and the experimental group on post test adjusted mean scores as measured on the Social Interest Scale. An analysis of covariance was employed to test the data. Behavior disordered students in the experimental group participated in three activities designed to develop their social interest. They participated in peer tutoring, socialization with nursing home residents, and group discussions. Data were collected from parents, teachers, and observers of behavior disordered students in an elementary school in Northwest Louisiana during the summer term of 1987. Teachers did report a statistically significant difference between the experimental and the control groups in the decrease of aggressive behavior. These results are in accord with predictions …

Aging Is a Determinant in Anoxia Stress Tolerance in Caenorhabditis Elegans
Oxygen availability is critical for survival for most organisms. The nematode, C. elegans, has been useful for studying genetic regulation of anoxia tolerance due to the oxygen deprivation response mechanisms shared with other metazoans. Studies examining long-term anoxia (72h, LTA) tolerance have only been conducted at adult day 1. To investigate the effect of aging on anoxia tolerance wild-type and mutant strains were exposed to LTA between adult day 1 and day 9. Wild-type isolates and daf-16(mu86) (FOXO transcription factor regulated by insulin-signaling) and aak-2(gt33) (catalytic subunit of AMP-activated protein kinase) strains were anoxia sensitive at day 1 and displayed increased LTA tolerance with aging correlated with reproductive senescence followed by a decline in survivorhsip through day 9. The daf-2(e1370) (insulin receptor homologue of C. elegans), glp-1(e2141) (a lin-12/Notch receptor) and fog-2(q71) (required for spermatogenesis) strains were LTA-tolerant through day 5. I conclude that aging influences LTA-tolerance in a strain- and age-dependent manner. In addition to being LTA-tolerant the daf-2(e1370) and glp-1(e2141) strains have a longevity phenotype that is suppressed by loss of kri-1 or daf-12. While loss of kri-1 did not suppress the LTA-tolerant phenotype of glp-1(e2141) at day 1 the portion of impaired survivors increased at day 3 …

An Agonizing Evolution: a History of the Texas National Guard, 1900-1945
The National Guard in America began in the Revolutionary War. The Texas units resulted from the earlier concept and emerged in 1835 to resist Mexican oppression. Following achievement of statehood, Texas militiamen served in the Mexican War, the Civil War, and the Spanish-American War. As the twentieth century began, Texans had a long history of service in reserve military organizations in spite of a prevailing attitude of contempt for citizen soldiers held by influential regular army officials.

AIDS Preventative Behavior Among Taiwanese University Students
This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vaccine. In addition, a majority of the students were either abstaining from sex or practicing monogamy. Using Pearson's correlation coefficient and multiple regression analysis, this study found that the psychological variables rather than cognitive variables significantly influenced the respondents' AIDS preventive behavior. Finally, suggestions were made for future research on AIDS, and for AIDS preventive behavior campaigns.

Airbourne WiFi Networks Through Directional Antenna: An Experimental Study
In situations where information infrastructure is destroyed or not available, on-demand information infrastructure is pivotal for the success of rescue missions. In this paper, a drone-carried on demand information infrastructure for long-distance WiFi transmission system is developed. It can be used in the areas including emergency response, public event, and battlefield. The WiFi network can be connected to the Internet to extend WiFi access to areas where WiFi and other Internet infrastructures are not available. In order to establish a local area network to propagate WIFI service, directional antennas and wireless routers are used to create it. Due to unstable working condition on the flying drones, a precise heading turning stage is designed to maintain the two directional antennas facing to each other. Even if external interferences change the heading of the drones, the stages will automatically rotate back to where it should be to offset the bias. Also, to maintain the same flying altitude, a ground controller is designed to measure the height of the drones so that the directional antennas can communicate to each other successfully. To verify the design of the whole system, quite a few field experiments were performed. Experiments results indicates the design is reliable, …

AirSniffer: A Smartphone-Based Sensor Module for Personal Micro-Climate Monitoring
Environmental factors can have a significant impact on an individual's health and well-being, and a primary characteristic of environments is air quality. Air sensing equipment is available to the public, but it is often expensive,stationary, or unusable for persons without technical expertise. The goal of this project is to develop an inexpensive and portable sensor module for public use. The system is capable of measuring temperature in Celsius and Fahrenheit, heat index, relative humidity, and carbon dioxide concentration. The sensor module, referred to as the "sniffer," consists of a printed circuit board that interconnects a carbon dioxide sensor, a temperature/humidity sensor, an Arduino microcontroller, and a Bluetooth module. The sniffer is small enough to be worn as a pendant or a belt attachment, and it is rugged enough to consistently collect and transmit data to a user's smartphone throughout their workday. The accompanying smartphone app uses Bluetooth and GPS hardware to collect data and affix samples with a time stamp and GPS coordinates. The accumulated sensor data is saved to a file on the user's phone, which is then examined on a standard computer.
