Are They Ready? a Multi-case Study of Traditional and Innovative Texas Teacher’s Perceptions of 21St Century Skills in Teaching and Learning
The 21st century is now in the second decade and the need for 21st century skills is discussed at all levels of education as necessary for student success in the future. Federal, state, and districts are addressing this need and have written technology plans to address 21st century skills needed. the purpose of this dissertation is to contribute to the knowledge of 21st century educational technology. the data includes seven recorded interviews from two separate research projects covering two models of education as teachers discuss teaching, learning, and technology. the data studied determines how educational technology perceived in the school environments has been integrated into the classrooms. the initial scripting of video interviews from two research projects began the analysis of data. Particular themes emerged in response to questions established by the two separate research projects focused on classroom, school, and district environmental arrangements that examined; teaching responsibilities and practices; student learning opportunities; and how technology is woven throughout instruction. Further exploration of themes stemmed from analysis conducted with the qualitative software program, NVivo 9. the themes discussed in this paper relate to instructor perceptions of teaching, learning, classroom procedures, and the role technology plays in each. Also noted are …

The Argei: Sex, War, and Crucifixion in Rome and the Ancient Near East
The purpose of the Roman Argei ceremony, during which the Vestal Virgins harvested made and paraded rush puppets only to throw them into the Tiber, is widely debated. Modern historians supply three main reasons for the purpose of the Argei: an agrarian act, a scapegoat, and finally as an offering averting deceased spirits or Lares. I suggest that the ceremony also related to war and the spectacle of displaying war casualties. I compare the ancient Near East and Rome and connect the element of war and husbandry and claim that the Argei paralleled the sacred marriage. in addition to an agricultural and purification rite, these rituals may have served as sympathetic magic for pre- and inter-war periods. As of yet, no author has proposed the Argei as a ceremony related to war. By looking at the Argei holistically I open the door for a new direction of inquiry on the Argei ceremony, fertility cults in the Near East and in Rome, and on the execution of war criminals.The Argei and new year’s sacred marriage both occurred during the initiation of campaign and spring planting and harvest season. Both in the ancient Near East and in Rome, animal victims were sacrificed …

The Art Car Spectacle: a Cultural Display and Catalyst for Community
This auto-ethnographic study focuses on Houston’s art car community and the grassroots movement’s 25 year relationship with the city through an art form that has created a sense of community. Art cars transform ordinary vehicles into personally conceived visions through spectacle, disrupting status quo messages of dominant culture regarding automobiles and norms of ownership and operation. An annual parade is an egalitarian space for display and performance, including art cars created by individuals who drive their personally modified vehicles every day, occasional entries by internationally renowned artists, and entries created by youth groups. A locally proactive public has created a movement has co-opted the cultural spectacle, creating a community of practice. I studied the events of the Orange Show Center for Visionary Art’s Art Car Weekend to give me insight into art and its value for people in this community. Sources of data included the creation of a participatory art car, journaling, field observation, and semi-structured interviews. The first part is my academic grounding, informed by critical pedagogy and socially reconstructive art practices. The second part narrates my experiences and understandings of the community along with the voices of others. Dominant themes of exploration include empowerment, community, and art. I …

An Assessment of Fruit Offerings for 7Th and 8Th Grade Students in Texas
Childhood obesity in America is reaching epidemic proportions. This study explored whether daily online lunch menu information was sufficient to enable parents to advise their children about healthy and unhealthy menu choices in 350 Texas middle schools and whether online menu information strongly correlated with the descriptions of the offerings given by 52 school cafeteria managers in telephone interviews. Although schools are making efforts to describe their offerings, they are not vigorously taking advantage of the opportunity to aggressively inform or educate. They are not coding their descriptions in such a way as to explicitly brand food as healthy or unhealthy. They are also not labeling food as generally required by law for consumer services that provide food (except for the fresh produce that lines supermarket shelves). Instead, they only briefly describe what they are serving in the way of fruit in one or two word snippets. Finally, cafeteria managers’ online descriptions were inconsistent with what they described in interviews. Online and verbal descriptions were sometimes contradictory, raising questions about the accuracy of either type of description.

Auditors’ Information Search and Documentation: Does Knowledge of the Client Preference Or PCAOB Accountability Pressure Matter?
Auditors regularly make judgments regarding whether a client’s chosen accounting policy is appropriate and in accordance with generally accepted accounting Principles (GAAP). However, to form this judgment, auditors must either possess adequate topic-specific knowledge or must gain such knowledge through information search. This search is subject to numerous biases, including a bias toward confirmation of a client’s preference. It is important to further our understanding of bias in auditors’ information search to identify its causes and effects. Furthering our understanding is necessary to provide a basis for recommending and evaluating a potential debiaser, such as accountability. the Public Company Accounting Oversight Board (PCAOB) annually inspects the audit files of selected engagements, which introduces a new form of accountability within the auditing profession. This new form of accountability has come at great cost, however, there is little empirical evidence regarding its effects on auditors’ processes. As such, it is important to understand whether the presence of accountability from the PCAOB is effective in modifying auditors’ search behaviors to diminish confirmation bias. Using an online experiment, I manipulate client preference (unknown vs. known) and PCAOB accountability pressure (low vs. high) and measure search type (information –focus or decision-focus), search depth (shallow or …

Automated Classification of Emotions Using Song Lyrics
This thesis explores the classification of emotions in song lyrics, using automatic approaches applied to a novel corpus of 100 popular songs. I use crowd sourcing via Amazon Mechanical Turk to collect line-level emotions annotations for this collection of song lyrics. I then build classifiers that rely on textual features to automatically identify the presence of one or more of the following six Ekman emotions: anger, disgust, fear, joy, sadness and surprise. I compare different classification systems and evaluate the performance of the automatic systems against the manual annotations. I also introduce a system that uses data collected from the social network Twitter. I use the Twitter API to collect a large corpus of tweets manually labeled by their authors for one of the six emotions of interest. I then compare the classification of emotions obtained when training on data automatically collected from Twitter versus data obtained through crowd sourced annotations.

Automatic Tagging of Communication Data
Globally distributed software teams are widespread throughout industry. But finding reliable methods that can properly assess a team's activities is a real challenge. Methods such as surveys and manual coding of activities are too time consuming and are often unreliable. Recent advances in information retrieval and linguistics, however, suggest that automated and/or semi-automated text classification algorithms could be an effective way of finding differences in the communication patterns among individuals and groups. Communication among group members is frequent and generates a significant amount of data. Thus having a web-based tool that can automatically analyze the communication patterns among global software teams could lead to a better understanding of group performance. The goal of this thesis, therefore, is to compare automatic and semi-automatic measures of communication and evaluate their effectiveness in classifying different types of group activities that occur within a global software development project. In order to achieve this goal, we developed a web-based component that can be used to help clean and classify communication activities. The component was then used to compare different automated text classification techniques on various group activities to determine their effectiveness in correctly classifying data from a global software development team project.

Back in My Hands: The Role of Self-Forgiveness and Stigma in HIV-Positive Adults
While advancements in treatment have made HIV a more manageable disease, only recently have psychosocial variables associated with the health of persons living with HIV (PLH) began to receive increased scrutiny. HIV-related stigma, considered by some researchers to be a “second epidemic,” is one such psychosocial variable and is associated with negative physiological and psychological health outcomes. In an effort to alleviate the effects of stress, increased research attention has focused on forgiveness as a teachable coping strategy. Current forgiveness interventions demonstrate encouraging results in decreasing anger and neutralizing stress but have not been applied to HIV-positive populations. In this study, Lazarus and Folkman’s transactional model of stress and coping (1984) and Prochaska and Velicer’s transtheoretical model of health behavior (1997) were utilized as theoretical frameworks to inform a randomized clinical trial that examines coping skills, particularly forgiveness, in PLH and perceived HIV-related stigma. An ethnically diverse sample of HIV-positive adults (n = 57) was randomized into a treatment or control group. The treatment group participated in six weeks of cognitive-behavioral group therapy that focused on the teaching of forgiveness as an effective coping tool while the control group was psychoeducational in nature and did not involve mention of forgiveness. …

Baseband Noise Suppression in Ofdm Using Kalman Filter
As the technology is advances the reduced size of hardware gives rise to an additive 1/f baseband noise. This additive 1/f noise is a system noise generated due to miniaturization of hardware and affects the lower frequencies. Though 1/f noise does not show much effect in wide band channels because of its nature to affect only certain frequencies, 1/f noise becomes a prominent in OFDM communication systems where narrow band channels are used. in this thesis, I study the effects of 1/f noise on the OFDM systems and implement algorithms for estimation and suppression of the noise using Kalman filter. Suppression of the noise is achieved by subtracting the estimated noise from the received noise. I show that the performance of the system is considerably improved by applying the 1/f noise suppression.

Bearing Strength of Cold Formed Steel Bolted Connections in Trusses
The existing design provision in North American Specification for Cold- Formed Steel Structural Member (AISI S100) for the bearing strength of bolted connections were developed from tests on bolted connected sheets which were restrained by bolt nut and head with or without washers. However, in the cold-formed assemblies, particularly in trusses, the single bolt goes through both sides of the connected sections, making the connected sheets on each side unrestrained. the warping of the unrestrained sheet may reduce the bearing strength of the bolted connection. This research investigates the behavior and strength of bearing failure in bolted connections in cold-formed steel trusses. Tensile tests were conducted on trusses connections with various material thicknesses. It was found that the AISI S100 works well for thick connections but provides unconservative predictions for thin materials. Based on the experimental results, a modified bearing strength method is proposed for calculating the bearing strength of bolted truss connections. the proposed method can be used for any cold-formed steel connections with unrestrained sheet.

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

Behavioral Aspects of Latino Familialism: a Three Study Analysis
The existing research on Latino familialism draws a distinction between the attitudes associated with familialism and familialism-based action. Because attitudes tend to be more stable when considering variables such as immigration generation status, etc., social science researchers tend to employ measures based on attitudinal aspects of familialism, rather than action or behavior. Because of this preference, there is a lack of studies that examine familialism-based action and behaviors. This dissertation consists of three unique studies that examine actions and behaviors associated with familialism, while taking into account the methodological concerns expressed by previous researchers. The first study uses nationally representative U.S. data to compare the differences in the frequency of contact with various family members, among black non-Hispanics, Hispanics, and white non-Hispanics. The central finding of this study is that Hispanics maintain more frequent contact with family than white non-Hispanics, but there is no difference between Hispanics and black non-Hispanics, with the exception of contact with fathers. The second study, which employs qualitative data collected from a metropolitan area in the Southwest U.S., examines the locus of educational aspirations and expectations among a sample of Hispanics and white non-Hispanics. Among other things, this study finds that Hispanic females were more …

Beta-adrenergic Blockade Via Atenolol and Its Effects on Blood Pressure, Heart Rate, and Renal Morphology in the Developing Chicken Gallus Gallus Domesticus
Chicken embryos were chronically exposed to the ?1- blocker atenolol during one of three stages: mesonephros (E7-E9), mesonephros-metanephros (E11-E13), or metanephros (E15-E17). Mesonephros group hearts were larger than all other groups (P < 0.01). Mesonephros and metanephros group kidneys were larger than all remaining groups (P < 0.0001). The mesonephros group nephron number was ~40% lower than control values (P = 0.002). Glomerular areas were 26% and 18% larger than the control group in the mesonephros and metanephros groups, respectively (P < 0.001). These data suggest an E7-E9 critical window of cardiovascular and renal development for atenolol. Acute atenolol exposure in E15 embryos showed an increase in mean arterial pressure with all but the highest dose. All doses significantly decreased heart rate.

Between Comancheros and Comanchería: a History of Fort Bascom, New Mexico
In 1863, Fort Bascom was built along the Canadian River in the Eroded Plains of Territorial New Mexico. Its unique location placed it between the Comanches of Texas and the Comancheros of the Sangre de Cristo Mountains. This post was situated within Comanchería during the height of the United States Army's war against the Southern Plains Indians, yet it has garnered little attention. This study broadens the scholarly understanding of how the United States Army gained control of the Southwest by examining the role Fort Bascom played in this mission. This includes an exploration of the Canadian River Valley environment, an examination of the economic relationship that existed between the Southern Plains Indians and the mountain people of New Mexico, and an account of the daily life of soldiers posted to Fort Bascom. This dissertation thus provides an environmental and cultural history of the Canadian River Valley in New Mexico, a social history of the men stationed at Fort Bascom, and proof that the post played a key role in the Army's efforts to gain control of the Southern Plains Indians. This study argues that Fort Bascom should be recognized as Texas' northern-most frontier fort. Its men were closer to …
