The Quest for Perfect Appearance: an Examination of the Role of Objective Self-awareness Theory and Emotions
Quality of appearance is important in nature and individuals have a basic need to establish the normality of appearance to confirm their acceptability to others. In daily inter-relationships of the same species, for instance, normal-appearing members of a species group reject or kill other members who appear abnormal. In human society, appearance is considered as one of the most direct sources of information about other people, and unattractiveness is often accompanied by negative judgments, which can cause emotional distress and isolation. Accordingly, humans tend to pay great attention to their personal appearance and make improvements to enhance their self-representations. The growth of the beauty and cosmetic surgery industries is an indication of an increasing willingness to enhance physical appearance. However, despite the growing demand for cosmetic procedures, the consumer research literature on this topic is extremely sparse. In fact, little is known about the attitudinal and motivational drivers that facilitate undergoing such procedures. This dissertation enriches our understanding of factors that affect consumers’ motivation to pursue cosmetic procedures and examines the role of emotions in such decisions. To that end, objective self-awareness (OSA) theory is applied and the interplay between the state of public OSA, beauty standards, and self-conscious emotions …

A Socio-ecological Assessment of Watershed Ecosystem Services in Southern Patagonia
This thesis utilizes a theoretical framework which links biophysical and social domains of ecosystems via ecosystem services (ES), in order to conduct a socio-ecological assessment of urban watersheds in three communities in Chilean and Argentine regions of southern Patagonia. Results from this study show that expanding urban areas may be undermining the ability of local watersheds to provide for high quality ES posing potential risks to community wellbeing. Secondly, researchers and decision makers influencing regional natural resource management share similar values to general community members but do not capture the diversity of values that exist within the broader community, and dialogue between these groups on management issues is poor. A community-based management structure is recommended for the creation of adaptive and locally relevant management strategies.

Theoretical and Experimental Investigations Concerning Microgels of Varied Spherical Geometries
Polymer gels have been studied extensively due to their ability to simulate biological tissues and to swell or collapse reversibly in response to external stimuli. This work presents a variety of studies using poly-N-isopropylacrylamide (PNIPA) hydrogels. The projects have been carried out both in the lab of Dr. Zhibing Hu and in collaboration with others outside of UNT: (1) an analysis of the swelling kinetics of microgel spherical shells prepared using a novel design of microfluidic devices; (2) a comparison of the drug-release rates between nanoparticle structures having either core or core-with-shell (core-shell) designs; (3) an investigation into the thermodynamics of swelling for microgels of exceedingly small size.

Jacques Ibert: an Analytical Study of Three Movements From Histoires
Although many biographical studies are available on Jacques Ibert, few contain significant analytical commentary. In this study I examine three movements from Ibert’s Histoires for piano which was composed between 1920 and 1921 and was premiered in 1923. The three movements are “La menuese de tortues d’or,” “Le petit âne blanc,” and “La marchande d’eau fraîche.” I primarily use Schenkerian analysis to identify characteristics of Ibert’s compositional language. Significant aspects of impressionism and Debussian influence are also identified as related elements to my analysis. Many expected elements of Schenkerian theory are absent in Histoires. The conclusions of this study are consistent with those of other analysts who apply Schenkerian methodology to impressionist music such as Richard Parks, Adele Katz, Felix Salzer, and Edward Laufer.

Testing a Comprehensive Model of Muscle Dysmorphia Symptomatology in a Nonclinical Sample of Men
As increasing emphases are placed on the importance of a muscular male physique in Westernized culture, more men are experiencing eating, exercise, and body image (EEBI) disturbances. Clinician-researchers have identified a syndrome, termed muscle dysmorphia (MD), in which individuals, usually men, are pathologically preoccupied with their perceived lack of muscularity. The current study tested a modified version of an extant theoretical model of MD symptomatology as well as an alternative model of MD symptomatology. Over 700 adult men completed a demographic questionnaire, a symptom inventory, a self-esteem questionnaire, a measure of perfectionism, a measure of the media’s influence on EEBI disturbances, and measures of body dissatisfaction and MD symptoms. Structural equation modeling (SEM) was used to examine the goodness of fit of the proposed models. Overall, the first model demonstrated poor fit with the data. Conversely, the alternative model fit the data adequately. The alternative model was cross validated with a second sample, and also fit this data adequately.

Value Development in Emerging Adulthood: the Influence of Family
The purpose of this study was to better understand value development in an emerging adult, college student population, and to further define, identify and clarify family characteristics that influence values. Theories have sought to examine the developmental influences in emerging adulthood, but little research exists examining the role of the family, particularly in regards to value development. The current study reviewed the literature on emerging adulthood, values, and self-determination theory with attention to family influence. Questions addressed in this study included: 1) are perceived parent values predictors of emerging adult values, 2) will the quality of communication between parents and emerging adults and the presence of an emotionally supportive relationship with both mother and father moderate the relationship between the perception of parent values and emerging adult values, and 3) does the family environment influence the types of values emerging adults perceive to be important to their parents? For this purpose, 200 college students completed 5 different self-report questionnaires measuring the constructs of values, perceived parent values, family environment variables, family communication variables, and quality of relationship with both father and mother. Parents of college students completed a self-report questionnaire measuring their socialization values for their children and a questionnaire …

Drive Level Dependence of Advanced Piezoelectric Resonators
Resonators are one of the most important parts of electronic products. They provide a stable reference frequency to ensure the operation of these products. Recently, the electronic products have the trend of miniaturization, which rendered the size reduction of the resonators as well [1]. Better design of the resonators relies on a better understanding of the crystals' nonlinear behavior [2]. The nonlinearities affect the quality factor and acoustic behavior of MEMS (Micro-Electro-Mechanical-System) and nano-structured resonators and filters [3]. Among these nonlinear effects, Drivel Level Dependence (DLD), which describes the instability of the resonator frequency due to voltage level and/or power density, is an urgent problem for miniaturized resonators [2]. Langasite and GaPO4 are new promising piezoelectric material. Resonators made from these new materials have superior performance such as good frequency-temperature characteristics, and low acoustic loss [2]. In this thesis, experimental measurements of drive level dependence of langasite resonators with different configurations (plano-plano, single bevel, and double bevel) are reported. The drive level dependence of GaPO4 resonators are reported as well for the purpose of comparison. The results show that the resonator configuration affects the DLD of the langasite resonator. Experiments for DLD at elevated temperature are also performed, and it …

Sleep Loss and Risk-taking Behavior
While sleep loss has been shown to have detrimental effects on cognitive, physiological, and psychological processes, it has only recently been investigated as a possible causal factor of risk-taking behavior (i.e., a conscious choice to engage in dangerous behavior despite knowledge of possible loss or harm). Among the few studies that have been conducted in this field, the majority found that as individuals become sleepier, their propensity to engage in risk-taking behavior increased. The results of the current study indicated a positive relationship between increased sleep loss and two measures of specific risk-taking behavior (i.e., substance use, sexual compulsivity), but no significant relationship between sleep loss and measures of general risk-taking behavior. There was some evidence for temporal stability of the Iowa Gambling Task (IGT), though scores on the IGT were not related to scores on other measures of risk-taking, nor to measures of sleep loss. Negative mood was found to partially mediate the relationship between sleep loss and substance use, as well as the relationship between sleep loss and sexual compulsivity.

Practical Astronomy
This dissertation is a collection of poems preceded by a critical preface. The preface considers Anthony’s Hecht’s long poem, “The Venetian Vespers,” and the ways in which the temporally unsettled situation of the poem’s speaker parallels a problem facing narrative-meditative poets. The preface is divided into two main sections that explore divisions of this larger conflict. The first discusses the origins and effects of the speaker’s uprootedness in time, and the ways in which he tries to both combat and embrace this dislocation by temporarily losing himself in the immediacy of observing visual art. In this section I connect the dilemma of the speaker, who wishes to escape his memory by focusing outwards, to the dilemma of a representational poet who, despite his position towards the past, must necessarily confront or recollect memories and emotions in order to create authentic descriptions or characters. The second section focuses on the production and appreciation of artistic works (both visual and literary) and how the meaning, production and appreciation of beauty are inseparable from its existence within the physical limits of time. Here I discuss the significance of Hecht’s character who is surrounded with beauty yet describes himself as a person who only …

The Impact of Quality on Customer Behavioral Intentions Based on the Consumer Decision Making Process As Applied in E-commerce
Perceived quality in the context of e-commerce was defined and examined in numerous studies, but, to date, there are no consistent definitions and measurement scales. Instruments that measure quality in e-commerce industries primarily focus on website quality or service quality during the transaction and delivery phases. Even though some scholars have proposed instruments from different perspectives, these scales do not fully evaluate the level of quality perceived by customers during the entire decision-making process. This dissertation purports to provide five main contributions for the e-commerce, service quality, and decision science literature: (1) development of a comprehensive instrument to measure how online customers perceive the quality of the shopping channel, website, transaction and recovery based on the customer decision making process; (2) identification of the determinants of customer satisfaction and the key dimensions of customer behavioral intentions in e-commerce; (3) examination of the relationships among perceived quality, customer satisfaction and loyalty intention using empirical data; (4) application of different statistical packages (LISREL and PLS-Graph) for data analysis and comparison of how these methods impact the results; and (5) examination of the moderating effects of control variables. A survey was designed and distributed to a total of 1126 college students in a …

Transformation of Themes, Controlled Pianistic Textures, and Coloristic Effects in Liszt's Hungarian Rhapsodies Nos 6, 10, and 12
Liszt's Hungarian Rhapsodies are uniformly considered highly challenging in terms of technical execution. However, their artistic value is frequently questioned. This dissertation examines the compositional elements that are often overlooked in these virtuoso works, and provides a viewpoint into their interpretative characteristics. Furthermore, it pursues a claim that besides being excellent performance pieces, these works also make an intriguing contribution to Liszt scholarship, and deserve meaningful consideration in terms of their artistic quality. Following the Introduction (Chapter 1), Chapter 2 provides a brief historical perspective of the critical affirmation Liszt the composer encountered from the musical society. It also includes a short background on Liszt's Hungarian Rhapsodies, as well as the general reactions these works evoked from pianists, audiences, and scholars, during the time they were composed to the present day. As the main body of the dissertation, Chapter 3 investigates the three primary compositional concepts found in Rhapsodies Nos. 6, 10, and 12. These concepts are divided into three subchapters: Transformation of Themes, Controlled Pianistic Textures, and Coloristic Effects. Each of these subchapters provides explanatory information, as well as some of the most characteristic passages presented.

On Steinhaus Sets, Orbit Trees and Universal Properties of Various Subgroups in the Permutation Group of Natural Numbers
In the first chapter, we define Steinhaus set as a set that meets every isometric copy of another set at exactly one point. We show that there is no Steinhaus set for any four-point subset in a plane.In the second chapter, we define the orbit tree of a permutation group of natural numbers, and further introduce compressed orbit trees. We show that any rooted finite tree can be realized as a compressed orbit tree of some permutation group. In the third chapter, we investigate certain classes of closed permutation groups of natural numbers with respect to their universal and surjectively universal groups. We characterize two-sided invariant groups, and prove that there is no universal group for countable groups, nor universal group for two-sided invariant groups in permutation groups of natural numbers.

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 …

Perception of Foreign Accented Speech: the Roles of Familiarity and Linguistic Training
This paper seeks to address the issue by examining two factors that potentially affect a listener’s perception of foreign accented speech: degree of familiarity (as acquired through a work or personal environment) and amount of ESL or linguistic training. Speech samples were recorded from 18 international students from Hispanic, Asian, and Middle-eastern backgrounds and across all proficiency levels as designated by their academic English program. Six native English speakers were also recorded to serve as a basis for comparison. Listeners were drawn from two pools: people with ESL and/or linguistic training (n=42) and laypersons with no such specialist training (n=36). After completing a background questionnaire to assess familiarity with foreign accented speech, each listener rated all 24 speech samples on the dimensions of comprehensibility, degree of accent, and communicative ability. Results indicate that participants with ESL/linguistic training rate foreign accented speech more positively on all three dimensions than laypersons with no such training. Additionally, degree of familiarity with foreign accented speech is positively correlated with how participants rated the accented speech samples. a number of highly significant interactions between these and other factors including sex of the speaker, proficiency level of the speaker, and L1 family of the speaker were …

Impact of Congruence Between Self-disclosed Personal Information and Review on Source Credibility in Online Travel Reviews
This experimental study examined the source-message congruence effect on source credibility by manipulating the congruence of the reviewer’s profile information (travel interest, geographical location) with no changes in the review content. the congruence effect was found to influence perceptions of the reviewer’s expertise in a travel interest. This finding suggests that revealing the reviewer’s travel interest can assist the credibility assessment of travel reviewers-particularly in terms of expertise-within the category of a travel interest. the refined classification of travel reviewers based on their travel interests can improve their usefulness as information sources for prospective travelers’ information searches. These attributes can further be employed as search cues if embedded in the reviewer’s profile.

No-thought Shopping: Understanding and Controlling Nonconscious Processing in Marketing
This dissertation explores how nonconscious thought processing might be affected and activated in ways that influence consumer decision making. To activate nonconscious thought processes, this dissertation relies on priming—the unobtrusive activation of mental representations by stimuli in a social context, which occurs without participants' conscious awareness. Three dimensions of consumer decision making are investigated: purchase intention, product evaluation and arousal. The dissertation is based on the auto-motive model of nonconscious goal pursuit and somatic marker hypothesis. The dissertation is driven by three experiments, which respectively explore crucial areas in priming effects and addresses the following research question: can primes be shaped or controlled by marketers? Specifically, the dissertation examines whether shopping behavior can be primed. Second, the dissertation also examines how facial primes displaying basic emotions (happiness, anger, contempt, disgust, fear, sadness, and surprise) can prime emotion and arousal. Finally the dissertation examines the effect of the interaction of the buying prime with the primes of faces displaying basic emotions on the dependent variables of purchase intention, product evaluation, emotion, and arousal. Results from three experimental studies show that shopping behavior can be primed, and primed participants will exhibit higher product evaluation than those exposed to a control prime. Second …

The Rise of the Republicans: Party Realignment in Twentieth Century Texas
This dissertation is a study of the political transformation of Texas during the twentieth century from a predominantly Democratic to a two-party state. It is commonly asserted that the fundamental conservatism of Texas voters led them to abandon the national Democratic Party as it embraced more liberal reforms. This shift led to a rise in support in Texas for the Republican Party, which continued to advocate a more conservative agenda. But this change demands a more thorough explanation at the local level, in part because such a study can also reveal other factors at work. This dissertation first examines how prohibition impacted the state's political status quo and provided an opportunity for the Republican Party to increase its numbers. It then discusses the New Deal and the growth of Texas's oil industry, and how government regulation shaped political developments. The impact of urbanization and suburbanization on Republican growth are also addressed, along with numerous campaigns that reflected the changes occurring in Texas's electorate during this time. Although Dwight D. Eisenhower's 1952 and 1956 wins in Texas were a strong indication of the realignment among Texas voters, it was John G. Tower's election to the United States Senate that served as …

Looting and Restitution During World War II: a Comparison Between the Soviet Union Trophy Commission and the Western Allies Monuments, Fine Arts, and Archives Commission
From the earliest civilizations, victorious armies would loot defeated cities or nations. the practice evolved into art theft as a symbol of power. Cultural superiority confirmed a country or empire’s regime. Throughout history, the Greeks and Romans cultivated, Napoleon Bonaparte refined, and Adolf Hitler perfected the practice of plunder. As the tides of Second World War began to shift in favor of the Allied Powers, special commissions, established to locate the Germans’ hoards of treasure, discovered Nazi art repositories filled with art objects looted from throughout Europe. the Soviet Union Trophy Commission and the Western Allies Monuments, Fine Arts, and Archives Commission competed to discover Nazi war loot. the two organizations not only approached the subject of plunder as a treasure hunt, but the ideology motivating both commissions made uncovering the depositories first, a priority. the Soviet trophy brigades’ mission was to dismantle all items of financial worth and ship them eastward to help rebuild a devastated Soviet economy. the Soviet Union wished for the re-compensation of cultural valuables destroyed by the Nazis’ purification practices regarding “inferior” Slavic art and architecture; however, the defeated German nation did not have the ability to reimburse the Soviet State. the trophy brigades implemented …
