Design and Implementation of Communication Platform for Autonomous Decentralized Systems
This thesis deals with the decentralized autonomous system, in which individual nodes acting like peers, communicate and participate in collaborative tasks and decision making processes. An experimental test-bed is created using four Garcia robots. The robots act like peers and interact with each other using user datagram protocol (UDP) messages. Each robot continuously monitors for messages coming from other robots and respond accordingly. Each robot broadcasts its location to all the other robots within its vicinity. Robots do not have built-in global positioning system (GPS). So, an indoor localization method based on signal strength is developed to estimate robot's position. The signal strength that the robot gets from the nearby wireless access points is used to calculate the robot's position. Trilateration and fingerprint are some of the indoor localization methods used for this purpose. The communication functionality of the decentralized system has been tested and verified in the autonomous systems laboratory.

Adult Attachment Patterns, Mental Representation of Self, and Faith: Mediators of Childhood Trauma and Affect-Behavior Regulations in Adulthood
The purpose of this study was to investigate psychological mechanism by which four intra- and inter-personal characteristics of an individual (anxious and avoidant adult attachment patterns, images of self, and religious faith) mediate the relationship between childhood trauma and each of three affect-behavior regulation problems in adulthood (symptoms of depression, disordered eating behaviors, and substance abuse). A total of 401 college student participants completed a packet of 18 surveys including 10 surveys used in the present study. Structural equation modeling was used to test each of three hypothesized structural models (Depression, Eating Disturbances, and Substance Abuse). A series of multi-group analyses conducted to test if each of three hypothesized models is invariant across gender indicated no significant difference between females and males. Thus, the data were combined across gender to test for mediated effects in each of three hypothesized models. The results indicated: (a) for the hypothesized model for depression, anxious attachment patterns, avoidant attachment patterns, and negative self-images, but not religious faith, fully mediated the relationship between childhood trauma and symptoms of depression; (b) for the model for eating disturbances, anxious attachment and negative images of self, but not avoidant attachment and religious faith, fully mediated the association between …

Alberto Ginastera and the Guitar Chord: An Analytical Study
The guitar chord (a sonority based on the open strings of the guitar) is one of Alberto Ginastera's compositional trademarks. The use of the guitar chord expands throughout forty years, creating a common link between different compositional stages and techniques. Chapters I and II provide the historical and technical background on Ginastera's life, oeuvre and scholar research. Chapter IV explores the origins of the guitar chord and compares it to similar specific sonorities used by different composers to express extra-musical ideas. Chapter V discusses Ginastera's initial uses and modifications of the guitar chord. Chapter VI explores the use of the guitar chord as a referential sonority based on Variaciones Concertantes, Op. 23: I-II, examining vertical (subsets) and horizontal (derivation of motives) aspects. Chapter VII explores uses of trichords and hexachords derived from the guitar chord in the Sonata for Guitar Op. 47.

Methodological Issues in Malingering Research: The Use of Simulation Designs
The accurate determination of malingering relies on the use of validated and clinically relevant assessment measures. Simulation design is the most often-used research design to accomplish this. However, its external validity is sometimes questioned. The goal of the thesis was to systematically evaluate these major elements: situation, incentives, and coaching. The situation in simulation studies can vary from relevant (academic failure in a college population) to irrelevant (capital murder) for the samples being studied. Incentives refer to the external motivation given to improve simulators' performance and can be positive (extra credit and monetary reward) or negative (extra time and effort). Finally, coaching refers to whether the participant receives any information on detection strategies that are designed to identify feigners. Using a large undergraduate sample in a factorial design, results indicate that a scenario familiar to the participants generally improved the believability of their responses. Coaching also improved the ability to feign convincingly, while incentive type was not associated with any change in scores. The implications of these findings for future research designs and the connection to practice are discussed.

Eighth Grade Science Teacher Quality Variables and Student Achievement
While No Child Left Behind ushered in the age of the "highly qualified" teacher, accountability focus has been shifted to the "highly effective" teacher, defined as teacher impact on student achievement. The Science Texas Assessment of Knowledge and Skills (TAKS) is used to judge the adequate yearly progress of students in Texas public schools. Therefore, the purpose of this study was to examine the relationship of teacher factors (i.e., ethnicity, gender, teaching experience, university selectivity, certification route, National Center for Education Statistics Locale/Code, number of science content and pedagogical course semester credit hours, grade point average for science content and pedagogical coursework) on student achievement using the eighth grade Science TAKS. The primary dependent variables were students' five objective scores and their overall scores on the eighth grade Science TAKS examination. The sample was 44 eighth grade science teachers and 4,119 students in Texas public schools. Multiple linear regression models enabled examinations of the relationships between teacher quality variables and student achievement. No significant relationships between the variables were found. Small effect sizes for the beta weights and structure coefficients occurred between teachers' science credit hours and TAKS objectives to explain 20% of the variance for TAKS Living Systems and …

The Variable use of ne in Negative Structures: An Apparent-Time Variationist Study of Synchronous Electronic French Discourse
This study of the variable use of ne in synchronous electronic French discourse follows the methodological guidelines and the theoretical framework proposed and subsequently elaborated by Labov for analyzing variable features of language. This thesis provides a quantitative variable rule (i.e., VARBRUL) analysis including age as a factor group (i.e., independent variable), thereby making a new contribution to this area of inquiry. The data (50,000 words from the vingtaine 'twentysomething' channel and 50,000 words from the cinquantaine 'fiftysomething' channel) are a subset of 100,000 words from a corpus of one million words collected in 2008 by the thesis director from the public chat server EuropNet. This study aims to answer the following overarching question: To what extent does age-compared to other factors-influence the variable use of ne in verbal negation in synchronous electronic French discourse? In order to answer this question, and possibly others, the VARBRUL analysis will include age, subject (e.g., noun vs. pronoun), type of second negative particle (e.g., pas 'not', jamais 'never', personne 'no one'/'nobody', and so forth), as well as verbal mood/tense.

Microstructure Evolution in Laser Deposited Nickel-Titanium-Carbon in situ Metal Matrix Composite
Ni/TiC metal matrix composites have been processed using the laser engineered net shaping (LENS) process. As nickel does not form an equilibrium carbide phase, addition of a strong carbide former in the form of titanium reinforces the nickel matrix resulting in a promising hybrid material for both surface engineering as well as high temperature structural applications. Changing the relative amounts of titanium and carbon in the nickel matrix, relatively low volume fraction of refined homogeneously distributed carbide precipitates, formation of in-situ carbide precipitates and the microstructural changes are investigated. The composites have been characterized in detail using x-ray diffraction, scanning electron microscopy (including energy dispersive spectroscopy (XEDS) mapping and electron backscatter diffraction (EBSD)), Auger electron spectroscopy, and transmission (including high resolution) electron microscopy. Both primary and eutectic titanium carbides, observed in this composite, exhibited the fcc-TiC structure (NaCl-type). Details of the orientation relationship between Ni and TiC have been studied using SEM-EBSD and high resolution TEM. The results of micro-hardness and tribology tests indicate that these composites have a relatively high hardness and a steady-state friction coefficient of ~0.5, both of which are improvements in comparison to LENS deposited pure Ni.

Postpartum Depression: A Sociocultural Quantitative and Qualitative Analysis of Adolescent and Adult Hispanic Mothers
This dissertation is a mixed methods analysis investigating postpartum depression as it is experienced by self-reported depressed Mexican American adolescent and adult mothers. The qualitative portion of this study explores pregnancy and motherhood to better understand meanings attached to depression. Six adolescent and six adult mothers, were recruited from the Dallas/Fort-Worth area. Each was interviewed twice, using semi-structured interview guides. The quantitative phase utilizes a national sample of self-reported depressed Hispanic mothers to identify breastfeeding behavior and mothers' perceptions of the physical health of their babies. Specifically, a secondary analysis of the National Survey of Children's Health, 2003 was used to supplement the qualitative data. This study provides a theoretical framework of fragmented identity to explain socio-cultural factors contributing to postpartum depression among Mexican American adolescent and adult mothers. Common themes leading to a fragmented identify were indentified. Contributors to postpartum depression include: unplanned pregnancy, internal struggle between cultures, body image and family conflict. Stigma associated with teen motherhood also contributed to depression among adolescent mothers while the medicalization of childbirth was a contributing factor of depression among the adult mothers. Additionally, the duration of breastfeeding and mothers' perceptions of their babies' physical health were impacted by depression, but breastfeeding …

Photoactivatable Quantum Dots in Super-Resolution Microscopy of Muscle
Super-resolution 3D imaging was achieved using newly synthesized photoactivatable quantum dot (PAQ dot) probes. Quantum dots were modified with a novel quencher system to make them photoactivatable. The unique properties of these PAQ dots enable single-fluorophore localization in three dimensions using a confocal microscopy optical sectioning method. Myosin and tropomyosin of rabbit myofibrilar bundles were specifically labeled with the newly synthesized PAQ dot. A sufficient number of single quantum dots were photoactivated, localized and reduced to their centroid and then reconstructed to a super-resolution image. The acquired super-resolution image shows a lateral and an axial sub-diffraction resolution and demonstrates ultrafine striations with widths less than 70 nm that are not evident by conventional confocal microscopy. The striations appear to be related to nebulin thin filament binding protein. This newly developed imaging system is cutting edge for its high resolution and localization as well its simplicity and convenience.

The Role of Attachment in the Intergenerational Transmission of Abuse: From Childhood Victimization to Adult Re-Victimization and Distress
Research indicates that victims of childhood abuse are at increased risk for transmitting violence in adulthood-a phenomenon known as the intergenerational transmission of abuse (ITA). Adult survivors of childhood victimization (i.e., child abuse or witnessed parental violence) are at increased risk for becoming abusive parents, perpetrators of intimate partner violence, and victims of intimate partner violence. The current study examined the latter form of ITA, in which a survivor of childhood victimization is re-victimized in adulthood by intimate partner violence. Attachment theory has been used to explain the ITA by positing that abuse is transmitted across generations via insecure attachment. The purpose of this study was to use structural equation modeling to test the attachment theory of ITA by examining the role of childhood and adult attachment in predicting re-victimization and symptoms of distress in adulthood. In the hypothesized model, childhood victimization by one's parents was hypothesized to predict adult intimate partner violence victimization through insecure attachment relationships in childhood (with one's parents) and adulthood (with one's partner). Furthermore, adult romantic attachment anxiety and attachment avoidance were hypothesized to predict different symptoms of distress. Self-report measures from 59 adult woman seeking services for intimate partner victimization at a domestic violence …

The Enemy of My Enemy: International Alliances Against Transnational Terrorist Organizations
A dearth of pre-existing research in the field prompted this thesis on whether traditional econometric analyses of war deterrent alliances are applicable to modern alliances for counter terror purposes. Apparent foundational and contextual differences between the two types of alliances and the costs and benefits member nations derive from each lead the author to theorize that factors contributing to the formation of each alliance are fundamentally similar. Multiple types of statistical models are used to measure variables from the Correlates of War and Polity datasets combined with custom variables in a new dataset concerning major transnational terrorist attacks and the resultant alliances in testing the effect of traditionally contributing formation factors on alliances against terrorism. The results indicate that some contributing factors are similar, extant analysis tools have utility and that further investigation is justified.
