Experimental Synchronization of Chaotic Attractors Using Control
The focus of this thesis is to theoretically and experimentally investigate two new schemes of synchronizing chaotic attractors using chaotically operating diode resonators. The first method, called synchronization using control, is shown for the first time to experimentally synchronize dynamical systems. This method is an economical scheme which can be viably applied to low dimensional dynamical systems. The other, unidirectional coupling, is a straightforward means of synchronization which can be implemented in fast dynamical systems where timing is critical. Techniques developed in this work are of fundamental importance for future problems regarding high dimensional chaotic dynamical systems or arrays of mutually linked chaotically operating elements. digital.library.unt.edu/ark:/67531/metadc278971/
An Experimental Technique for the Objective Quantification of Body-Image Distortion
The purpose of this study was to develop an experimental technique to objectively measure the deviation between an individual's perception of his body image and his actual image. In addition, this technique was utilized to compare the accuracy of perception of body image between institutionalized and non-institutionalized individuals. Half of each subject category was also compared in terms of performance on an additional perceptual task unrelated to body image. digital.library.unt.edu/ark:/67531/metadc131426/

Expertise Revisited: Reflecting on the Intersection of Science and Democracy in the Case of Fracking
This dissertation aims to explain the conditions under which expertise can undermine democratic decision making. I argue that the root of the conflict between expertise and democracy lies in what I call insufficiently “representative” expertise – that is forms of scientific research that are not relevant to the policy questions at hand and that fail to make visible their hidden values dimensions. I claim that the scholarly literature on the problem of expertise fails to recognize and address the issue correctly, because it does not open the black box of scientific methodologies. I maintain that only by making sense of the methodological choices of experts in the context of policy making can we determine the relevance of research and reveal the hidden socio-political values and consequences. Using the case of natural gas fracking, I demonstrate how expert contributions – even though epistemically sound – can muddle democratic policy processes. I present four case studies from controversies about fracking to show how to contextualize scientific methodologies in the pertinent political process. I argue that the common problem across all case studies is the failure of expertise to sufficiently represent stakeholders’ problems and concerns. In this context, “representation” has three criteria: (1) the operational research questions on which the qualified experts work are relevant to stakeholders’ problems and concerns; (2) the non-epistemic values and consequences of epistemic choices of experts are compatible with social and political values and priorities; and (3) hidden values attached to facts are fully transparent and openly debated. In the conclusion, I propose a normative version of this representation theory that can be used to evaluate the appropriateness of expertise for democratic policy making. Instead of the value-free science ideal, I propose a new ideal to legitimately allow non-epistemic values in scientific reasoning without compromising the soundness of research. digital.library.unt.edu/ark:/67531/metadc822786/

Explaining Buyer Opportunism in Business-to-Business Relationships
The interaction among firms in the supply chain is necessary for business process execution and relationship success. One phenomenon of great significance to buyer-supplier relationships is opportunism. Opportunism is defined as behavior that is self-interest seeking with guile. It is manifested in behaviors such as stealing, cheating, dishonesty, and withholding information. Opportunism negatively impacts relational exchange tenets such as trust, commitment, cooperation, and satisfaction. Furthermore, perceptions of opportunism negatively affect firm performance. In lieu of the known negative effects of opportunistic behavior on buyer-supplier relationships, why do agents continue to engage in opportunistic tactics with their exchange partners? A comprehensive examination is necessary in order to understand why sourcing professionals engage in acts of opportunism. Understanding why opportunism occurs will reveal how to deter it, and this remains a gap in the literature. Based on theories in economics, marketing channels, supply chain management, decision science, and psychology, a comprehensive model tested a set of factors hypothesized to drive the use of opportunistic tactics. Factors include buyer-supplier relationship-specific factors, environmental factors, individual personality-related factors, and situational factors. Data was collected via internet survey of sourcing professionals from private industry and government agencies. Common to many studies of ethics, respondents made choices based on two hypothetical vignettes. Two logistic regression models were used to test the hypotheses. Factors found to affect buyer opportunism included buyer power, corporate ethical values, pressure to perform, leadership opportunism, business sector, honesty/integrity, and subjective expected utility. This research contributes to theory by combining several disparate theories to best explain opportunism. A comprehensive evaluation should determine which theory explains the most variance in decision making. The study contributes to practice by identifying those important factors contributing to a sourcing professional's decision to use opportunistic tactics. The ability to manage these factors should improve the probability of relationship success. Additionally, the identification of these factors should help leaders to make more accurate estimates of transaction costs - key knowledge required to make an informed make or buy governance decision. digital.library.unt.edu/ark:/67531/metadc3664/
Explaining Economic Development Strategies Using Product Differentiation Theory: a Reconceptualization of Competition Among City Governments
Access: Use of this item is restricted to the UNT Community.
Local governments do not operate in a vacuum. Instead, they are part of a complex “polycentric” system of governments where politically autonomous and self-ruled cities compete with one another over taxable wealth. Missing from the scholarship on metropolitan governance is an understanding of the factors driving competition among local governments. The purpose of this dissertation is to fill this gap by examining how interjurisdictional competition over economic development impacts a city’s choice of strategies for attracting business and residential investment and how those strategies affect revenue collection. First, this dissertation examines whether cities, knowing the economic development strategies of their neighboring cities, pursue similar types of businesses? Or do cities strategically target different types of businesses as a way to avoid the negative consequences of competition? Second, this dissertation explores what impact the decision to pursue similar or dissimilar businesses has on the revenue collection of local governments. Using spatial data analysis to analyze a sample of 2,299 cities, this dissertation finds general support for both theoretical frameworks presented. Overall, the findings from both analyses provide unique insights into metropolitan governance and interjurisdictional competition. digital.library.unt.edu/ark:/67531/metadc801942/
Explaining “Everyday Crime”: A Test of Anomie and Relative Deprivation Theory
Every day, individuals commit acts which are considered immoral, unethical, even criminal, often to gain material advantage. Many people consider cheating on taxes, cheating on tests, claiming false benefits, or avoiding transport fare to be wrong, but they do them anyway. While some of these acts may not be formally illegal, they are, at best, considered morally dubious and is labeled “everyday crime.” Anomie theory holds that individuals make decisions based on socialized values, which separately may be contradictory but together, balances each other out, producing behavior considered “normal” by society. When one holds an imbalanced set of values, decisions made on that set may produce deviant behavior, such as everyday crime. RD theory holds that individuals who perceive their own deprivation, relative to someone else, will feel frustration and injustice, and may attempt to ameliorate that feeling with deviant behavior. Data from the 2006 World Values Survey were analyzed using logistic regression, testing both constructs concurrently. An individual was 1.55 times more likely to justify everyday crime for each calculated unit of anomie; and 1.10 times more likely for each calculated unit of RD. It was concluded from this study that anomie and relative deprivation were both associated with the tendency towards everyday crime. digital.library.unt.edu/ark:/67531/metadc103334/
Explaining Juvenile Delinquency: A Test of Robert Agnew's General Strain Theory, Utilizing the National Longitudinal Study of Adolescent Health Data
Strain theory has a long academic lineage for explaining criminal and deviant behavior from the classical writings of Emile Durkheim to the contemporary writings of Robert Agnew. The purpose of this research is to conduct an empirical test of Agnew's general strain theory utilizing Wave 1 data from the 1994-1996 National Longitudinal Study of Adolescent Health data (Add Health) (N = 6,503). Utilizing the Add Health data set represents a new attempt at empirically evaluating Agnew's theory. Scales were constructed by the author operationalizing the propositions of general strain theory utilizing variables from this data set. Regression was used to find out if juvenile delinquency is associated with Agnew's general strain theory. Research findings show that taken together, the propositions of general strain theory, cumulative measures of failure to achieve goals, loss of valued objects and introduction of stressful events are all statistically significant predictors of juvenile delinquency. Regression and scale correlations indicated a low positive relationship between juvenile delinquency and Agnew's general strain theory propositions. This study represents an attempt in utilizing a data set which has not been used before to empirically test general strain theory. digital.library.unt.edu/ark:/67531/metadc5500/
Explaining Marijuana Use Among Turkish Juveniles: A Test of Hirschi's Social Bonding Theory
Marijuana is the most prevalent illicit drug used in the world and among Turkish juveniles. Although studies have examined marijuana use among Turkish juveniles, none has tested Hirschi's social bonding theory, one of the most frequently tested and applied criminological theories in the United States and other Western and developed countries. This study investigated the empirical validity and generalizability of Hirschi's theory to juveniles' marijuana use in Turkey, a non-Western and developing country. Data on 2,740 Turkish tenth grade students from the 2006 Youth in Europe survey were used. Results from binary logistic regression analyses were generally consistent with the propositions of Hirschi's theory and the findings of previous empirical studies. Regarding the attachment component of the theory, Turkish juveniles who lived in two-parent families and those who were closely monitored by their parents were less likely to have tried marijuana. In addition, teens who were strongly attached to their school and religion were also less likely to have used the drug. As for the commitment component, language grade was negatively associated with marijuana use. None of the involvement items had significant effects on marijuana use in the predicted direction. Participation in club sports had a positive effect on marijuana use. Belief items, such as acceptance of societal norms, values, and rules, had the predicted inhibiting effects on teens' marijuana use. Of the six sociodemographic/controls included in the analyses, only gender had a significant effect; male students were more likely to have tried marijuana than the female peers. Policy implications of the results for adolescents, parents, and schools are discussed. digital.library.unt.edu/ark:/67531/metadc33137/
Explaining the Relationship Between Borderline Personality Features and Suicidal Ideation
Researchers have previously identified substance use and borderline personality disorder as factors that increase risk for suicidal thoughts and behaviors. This study explored the relationship between these factors in samples of students and individuals seeking outpatient treatment. Supplemental data collected via the internet (MTurk) also looked at experiential avoidance (EA) with the Avoidance and Fusion Questionnaire for Youth. The Structured Clinical Interview for the DSM-IV, Alcohol Use Disorders Identification Test, Scale for Suicide Ideation, and Personality Assessment Inventory- Borderline Features Scale elicited information regarding severity and/or frequency of substance use, suicidal thoughts, and borderline features respectively. Additionally, the Psychiatric Diagnostic Screening Questionnaire was administered to the UNT sample. The UNT sample analyses indicate substance use moderates, strengthening, the relationship between borderline features and current suicidal thoughts. However, severity of suicidal thoughts was lower for individuals high in both borderline features and substance use disorder symptoms compared to those low in borderline features and high in substance use symptoms. The MTurk sample analyses suggest substance use functions as a mediator. A robust relationship existed between substance use severity and EA, showing substance use as a behavioral marker for EA. In conclusion, concurrent treatment of substance use and borderline personality features would be beneficial in reducing risk for suicidal thoughts. Further investigation into the role and utility of addressing EA is warranted. digital.library.unt.edu/ark:/67531/metadc699872/
Explanation for the Variation of Women’s Rights Among Moderate Muslim Countries
Due to the actions of radicals and extremists, many in the West have come to view Islam as a religion of gender inequality that perpetuates the severe oppression of women. However, there is actually great variation in women’s rights across Muslim countries. This thesis presents a theoretical framework seeking to explain this variation, by examining differences in family law. The theory supposes that variation can be explained by the strategic actions of political leaders. From this theory, I hypothesize that the variations in women’s rights come from the variation in family law, which in large, are due to the existence of groups threatening the power of the political leaders, and the leader’s subsequent understanding of this threat. Using a most similar systems research design, I examine 4 moderate Muslim countries, Turkey, Tunisia, Morocco, and Egypt. Through case study research, I find limited support for the above hypothesis. digital.library.unt.edu/ark:/67531/metadc149664/
Explanatory Style and College Performance in Students with Physical Disabilities
Seventy students (38 with physical disabilities and 32 without physical disabilities) were matched on age (a criterion of ± 4 years was used) and sex. Members of both groups, Persons With Physical Disabilities (PWPD) and those Persons Not Physically Disabled (PNPD), were asked to complete the University Services Inventory, Academic Goals Questionnaire, Academic Attributional Style Questionnaire (AASQ), and Beck Depression Inventory (BDI) to determine how these variables were related to explanatory style (ES, as determined by AASQ scores). ES has its origins in the reformulated learned helplessness model (Abramson, Seligman, & Teasdale, 1978). According to this model, individuals who made attributions that were internal-stable-global (pessimistic ES) were more likely to experience mood and behavior deficits in the wake of bad events. The present study examined college achievement (GPA), utilization of university services, goal specificity, goal efficacy, and responses to academic setbacks, as these variables were related to ES. Additionally, ES scores were examined with regards to differences in gender and disability status (both between different disability groups and between individuals with and without physical disabilities). digital.library.unt.edu/ark:/67531/metadc278608/
Explicating the Managerial Processes of Dynamic Capabilities and Investigating How the Reconceptualized Construct Influences the Alignment of Ordinary Capabilities
In the last three decades, strategic management scholars have explored the organization’s need to reconfigure its capabilities to leverage opportunities in a changing environment. The first objective of this study was to identify the underlying elements of the managerial processes of dynamic capabilities, and to offer a reconceptualization of the dynamic capabilities construct. The second objective of this investigation was to determine how the reconceptualized dynamic capabilities construct could influence the alignment of ordinary capabilities. Findings from this investigation indicate that organizational processes and managerial processes are unique components of dynamic capabilities. In addition, these organizational processes were found to be significantly and positively correlated with the alignment of ordinary capabilities. Furthermore, managerial processes were found to moderate the relationship between organizational processes and one type of ordinary capability alignment (i.e. innovation-operations capability alignment). Taken together, the findings of this study support the notion that dynamic capabilities are context specific, and that understanding how they influence the organization’s ability to change is complex. The developments and findings in this study offer a reconceptualized and empirically tested framework for the capability alignment process, thereby providing a more comprehensive picture of the underlying processes. digital.library.unt.edu/ark:/67531/metadc700096/

An Exploration of Altruistic Behavior of Substance-Abuse Facilities According to Their Ownership Status
Using the 2009 National Survey of Substance Abuse Treatment Services (N-SSATS), this paper uses logistic regressions to explore the effect of facility ownership on a facility’s show of altruism. Facility’s show of altruism is operationalized as a facility offering free treatment to all its clients, free treatment to some of its clients, or a facility offering a sliding fee scale to its client base in order to absorb some of the cost of treatment based on a potential client's income. Region, receipt of public funds, and religious affiliation are added as covariates in order to gauge whether the potential relationship between facility ownership and a facility’s show of altruism is genuine. Results indicate that private, for-profit ownership status of a facility is associated with a lower likelihood that a substance-abuse treatment facility would engage in altruistic behavior. However, receipt of public funds acts as a mediating variable, in that, its inclusion raises the likelihood that a private, for-profit facility would engage in shows of altruism. Furthermore, it appears that religious-affiliation increases the likelihood that a facility would display altruism by providing free treatment, to some of its clients, or to all, but less likely to display altruism by employing a sliding fee scale. Overall, inclusion of region, receipt of public funds, and religious affiliation all produce statistically significant results, along with facility ownership. This suggests that there are a variety of variables, apart from facility ownership alone, that might be influential over a facility's show of altruism. digital.library.unt.edu/ark:/67531/metadc103317/

Exploration Of Energy And Area Efficient Techniques For Coarse-grained Reconfigurable Fabrics
Coarse-grained fabrics are comprised of multi-bit configurable logic blocks and configurable interconnect. This work is focused on area and energy optimization techniques for coarse-grained reconfigurable fabric architectures. In this work, a variety of design techniques have been explored to improve the utilization of computational resources and increase energy savings. This includes splitting, folding, multi-level vertical interconnect. In addition to this, I have also studied fully connected homogeneous and heterogeneous architectures, and 3D architecture. I have also examined some of the hybrid strategies of computation unit’s arrangements. In order to perform energy and area analysis, I selected a set of signal and image processing benchmarks from MediaBench suite. I implemented various fabric architectures on 90nm ASIC process from Synopsys. Results show area improvement with energy savings as compared to baseline architecture. digital.library.unt.edu/ark:/67531/metadc103413/
Exploration of hierarchical leadership and connectivity in neural networks in vitro.
Living neural networks are capable of processing information much faster than a modern computer, despite running at significantly lower clock speeds. Therefore, understanding the mechanisms neural networks utilize is an issue of substantial importance. Neuronal interaction dynamics were studied using histiotypic networks growing on microelectrode arrays in vitro. Hierarchical relationships were explored using bursting (when many neurons fire in a short time frame) dynamics, pairwise neuronal activation, and information theoretic measures. Together, these methods reveal that global network activity results from ignition by a small group of burst leader neurons, which form a primary circuit that is responsible for initiating most network-wide burst events. Phase delays between leaders and followers reveal information about the nature of the connection between the two. Physical distance from a burst leader appears to be an important factor in follower response dynamics. Information theory reveals that mutual information between neuronal pairs is also a function of physical distance. Activation relationships in developing networks were studied and plating density was found to play an important role in network connectivity development. These measures provide unique views of network connectivity and hierarchical relationship in vitro which should be included in biologically meaningful models of neural networks. digital.library.unt.edu/ark:/67531/metadc9775/
An Exploration of Object Relations and the Early Working Alliance in a University Clinic Sample
The current study investigated the relationship between clients' object relations functioning and the working alliance. The Social Cognition and Object Relations Scale (SCORS; Westen, 1991), an object relations scoring system for the TAT, was used to assess object relations functioning. Forty-eight therapy clients at a university-based training clinic were administered the TAT, Adult Attachment Scale (AAS), Symptom Checklist 90-Revised (SCL-90-R; Derogatis, 1977), and the short form of the Marlowe-Crowne Social Desirability Scale (MCSD; Crowne & Marlowe, 1960). Following the initial assessment of client characteristics shortly after intake, clients and their therapists rated the working alliance 3 sessions later. Results indicated that the SCORS was significantly correlated with client and therapist ratings of the working alliance. The current study also assessed the predictive validity of the SCORS by examining how its various scales are related to aspects of the working alliance and the other measures used in this study. The findings suggest that the relationship between object relations functioning, the working alliance, symptom severity, and attachment disturbance depends on the aspect of object relations that is being assessed. digital.library.unt.edu/ark:/67531/metadc4583/
An exploration of parental sensitivity and child cognitive and behavioral development.
The current study attempted to show the relationship of paternal sensitivity and maternal sensitivity and their possible influences on child cognitive and behavioral development. This study used data collected as part of the National Institute for Child Health and Human Development (NICHD) Study of Early Child Care, which is a longitudinal, multi-site study. Correlation and regression analyses were computed to examine relationships between the variables at child age 6 and 36 months. Results indicated paternal sensitivity was a significant positive predictor of child cognitive abilities and a negative predictor of both fathers' reports of children's externalizing and internalizing behaviors. Maternal sensitivity was a significant negative predictor of mothers' reports of children's externalizing behaviors. Interpretations of these results and directions for future research are discussed. digital.library.unt.edu/ark:/67531/metadc5794/
An Exploration of Parenting Styles’ Impact on the Development of Values
The term emerging adulthood was coined during the 21st century to describe human development between adolescence and adulthood, during the ages of 18-25 (Arnett, 2000). During this stage, individuals can explore life areas. Emerging adults beginning college have a unique opportunity to form their identities and develop value systems (Hauser & Greene, 1991). With increasing autonomy, college students have possibilities for positive development and risk; values may be imperative in that differentiation. Furthermore, value systems are believed to play a major role in decision-making (Schwartz, 1992). Parents are influential in values development (Simpson, 2001; Steinberg & Sheffield Morris, 2001). During emerging adulthood, individuals have opportunities to notice discrepancies between their parents’ value system and society. Thus, emerging adults evaluate and choose personal values, which may or may not be similar to those of their parents, peers, or broader culture. Findings from this study indicate female caregivers’ parenting styles and closeness of the parent-child relationship have significant direct effects on the degree to which values are freely chosen. Specifically, Authoritarian parenting style (β = -.43 B = -1.70, p < .001), Authoritative parenting style (β = .12, B = .53, p < .001), and Emotional Support (β = .30, B = 6.80, p < .001) significantly predicted the degree to which values are intrinsically chosen. Only one significant relationship was found for male caregivers; there was a significant positive relationship between the authoritative parenting style and quality of the parent-child relationship (β = .64, B = .10, p < .001). digital.library.unt.edu/ark:/67531/metadc804871/
Exploration of Sculpture
Access: Use of this item is restricted to the UNT Community.
The images that I sculpt deal with reflections of human traits. Wood lends itself to this endeavor, offering minimal resistance to manipulation. Keeping the origin and qualities of the material while manipulating it into another object is a statement within itself. Letting the wood do what it does naturally keeps the viewer in touch with the fact it is still just an object of nature. Wood does not make itself any less real because of the relationship of the sculpture to it as wood. digital.library.unt.edu/ark:/67531/metadc5841/
The Exploration of Surface and Texture on the Inside and Outside of My Sculpture
After generating work for many years in an intuitive, “truth to materials” mindset my intent was to explore the interior possibilities of my sculptural forms and relate these if possible, to the exterior. Alongside this exploration of the interior I introduced surface texture and color onto both interior/exterior surfaces. In some cases the work had undergone a change, which lent new meaning and provided new relationships to exist between the interior/exterior of my sculpture. Not all of the work was satisfactory to me, though I feel there were many positive results from work that may not have been successful. I found that the integration of the interior/exterior dialogue into my existing work provided new meaning allowing new relationships within the work that had not existed previously. digital.library.unt.edu/ark:/67531/metadc3339/
An Exploration of Teachers' Adoption of the Bring Your Own Technology Program
The purpose of this study was to explore teachers' concerns, use, and actual practices in their adoption of the bring your own technology (BYOT) initiative. Twelve secondary teachers in a private school setting participated in this study. The participants represented all content areas including reading, math, science, and electives. The private school was in its third year of implementing BYOT. This case study incorporated multiple methods to collect data to gain a better understanding of teachers' adoption of an innovation, BYOT. The concerns-based adoption model (CBAM) was used as a theoretical framework. All three CBAM tools provided data: the Stages of Concern Questionnaire (SoCQ), levels of use interview protocol (LoUIP), and the innovation configuration (IC) map. Twelve of the participants completed the SoCQ across three different points in time. Six of the twelve teachers participated in three one-on-one interviews, including the LoUIP. Additionally, six teachers were observed in their classrooms during instruction. After triangulating all pieces of data, the majority of teachers had highest concerns related to self. Teachers were concerned about their ability to implement the innovation and managing BYOT in their classroom. Four of the six teachers had a level of use (LoU) at mechanical, and two teachers had a LoU at routine. The teachers' LoU indicated that they are using BYOT in the classroom; however, the majority of teachers observed had adoption practices mostly in the non-ideal variations of IC. The teachers' LoU and IC indicated that teachers had implemented BYOT in their own way and not necessarily in alignment with the campus' vision or expectations. This case study had several limitations, including the small number of participants and the brevity of classroom observations. Additionally, this study was limited to one school setting. Recommendations for future research include exploring teachers' adoption of BYOT in various school settings (i.e., both public and private schools) and teachers at the elementary, middle, and high school levels. Researchers should consider exploring the impact of specific interventions and support on teachers' adoption. digital.library.unt.edu/ark:/67531/metadc283863/
An Exploration of the Criterion and Construct Validity of the Self-compassion Scale
Past research indicates that self-compassion has positive implications for psychological health and functioning. However, as a newly specified construct, the literature regarding self-compassion could benefit from a more thorough validation of the primary scale used in this area of research, the Self-Compassion Scale. In the present study, structural path analysis (using Amos) was used to explore the criterion validity of the SCS with four variables which have been theorized to be relevant to self-compassion (caregiver emotional responsiveness, fear of emotion, internalized spirituality, and achievement goal orientation). Initial hypothesis testing indicated support for the path model, with the exception of achievement goals which were not significantly associated with self-compassion. Trimming these paths in a subsequent analysis improved model fit. Interestingly, further analyses of the model indicated that the pairing of participant and parent gender produced substantial differences in path coefficients. Next, correlational and factor analytic methods were used to test the construct validity of the SCS. Correlational analyses found adequate convergent construct validity but some lack of divergent validity between SCS dimensions and conceptually similar constructs (i.e., fear of emotion, social connectedness and self-criticism). Confirmatory factor analysis indicated that a two-factor model fit the data better than the one-factor model proposed by the author of the SCS. The incremental validity of the two-factor model was supported by incorporating a two-factor SCS in the path analysis. In sum, these findings generally support the criterion validity of the SCS through meaningful associations with theoretically relevant variables but cautions that these associations are strongly influenced by gender. It is also strongly recommended that a two-factor model of the SCS be explored in further research to ascertain its incremental utility for understanding self-compassion’s positive effects on psychological health. digital.library.unt.edu/ark:/67531/metadc699856/
An exploration of the diffusion of a new technology from communities of practice perspective: Web services technologies in digital libraries.
This study explored and described decision factors related to technology adoption. The research used diffusion of innovations and communities of practice (CoP) theoretical frameworks and a case study of Web services technology in the digital library (DL) environment to develop an understanding of the decision-making process. A qualitative case study approach was used to investigate the research problems and data were collected through semi-structured interviews, documentary evidence (e.g., meeting minutes), and a comprehensive member check. The research conducted face-to-face and phone interviews with seven respondents with different job titles (administraive vs. technical) from five different DL programs selected based on distinctive characteristics such as size of the DL program. Findings of the research suggested that the decision-making process is a complex process in which a number of factors are considered when making technology adoption decisions. These factors are categorized as organizational, individual, and technology specific factors. Further, data showed that DL CoPs played an important role in enabling staff members of a DL program to access up-to-date and experienced-based knowledge, provided a distributed problem solving and learning environment, facilitating informal communication and collaborative activities, and informing the decision-making process. digital.library.unt.edu/ark:/67531/metadc3930/
An Exploration of the Ground Water Quality of the Trinity Aquifer Using Multivariate Statistical Techniques
The ground water quality of the Trinity Aquifer for wells sampled between 2000 and 2009 was examined using multivariate and spatial statistical techniques. A Kruskal-Wallis test revealed that all of the water quality parameters with the exception of nitrate vary with land use. A Spearman’s rho analysis illustrates that every water quality parameter with the exception of silica correlated with well depth. Factor analysis identified four factors contributable to hydrochemical processes, electrical conductivity, alkalinity, and the dissolution of parent rock material into the ground water. The cluster analysis generated seven clusters. A chi-squared analysis shows that Clusters 1, 2, 5, and 6 are reflective of the distribution of the entire dataset when looking specifically at land use categories. The nearest neighbor analysis revealed clustered, dispersed, and random patterns depending upon the entity being examined. The spatial autocorrelation technique used on the water quality parameters for the entire dataset identified that all of the parameters are random with the exception of pH which was found to be spatially clustered. The combination of the multivariate and spatial techniques together identified influences on the Trinity Aquifer including hydrochemical processes, agricultural activities, recharge, and land use. In addition, the techniques aided in identifying areas warranting future monitoring which are located in the western and southwestern parts of the aquifer. digital.library.unt.edu/ark:/67531/metadc84218/

It is proposed in this thesis to explore the possible use of the Sociometric test as a measure of the personal social factor in old age. It is further proposed to gather sociometric data by administering a sociometric test to the residents of two homes for aged persons in Dallas County, Texas, and to illustrate by sociograms and tables the uses for which such data might be of value in research designed to investigate the personal social factor in old age. digital.library.unt.edu/ark:/67531/metadc83763/
An Exploration of the Relationship Between Principal Leadership Efficacy, Principal Computer Self-Efficacy, and Student Achievement
The purpose of this study was to examine whether or not relationships exist between principals' technology proficiency and student achievement as indicated by 2008 Texas Assessment of Knowledge and Skills (TAKS) ninth grade reading scaled scores. Secondly, the study examined whether or not relationships exist between principals' leadership self efficacy and student achievement as indicated in the 2008 Texas Assessment of Knowledge and Skills (TAKS) ninth grade reading scaled scores. Lastly, the select principal's personal and school demographic variables (principal gender, total years of experience as a professional, total years as principal at current school, total years of principal experience, highest degree earned, school economic status, school size) were considered within the study. The survey instruments used in this study were the Technology Proficiency Self Assessment Scale (TPSA) developed by Ropp in 2000 and the Principal's Self-Efficacy Scale (PSES) developed by Tschannen-Moran and Garies in 2004. A total of 129 Texas principal's participated in the study. Multiple regressions were utilized and effect size was considered to determine the strength of the relationship between variables. A statistical significance was found relating to the school's social economic status only when using both the PSES and the TPSA instruments. The effect sizes reported were all moderate, which acknowledged that relationships did exist between all predictor variables tested. Based on the information provided for B weights, School's SES was found to be the best predictor of reading TAKS achievement, preceded by Principal's Highest Degree Earned and Gender. SPSS 16.0 was used to analyze all data. This study adds to the literature on principals' technology efficacy and principal's self efficacy. digital.library.unt.edu/ark:/67531/metadc28399/
An Exploration of the Relationship between Worry and Other Verbal Phenomena
This study hypothesized a direct relationship among three verbal phenomena: derived relational responding, verbal intelligence, and worry. It also hypothesized that experiential avoidance would mediate the relationship between derived relational responding and worry. Overall, results from this study failed to support a relationship between worry and the other two verbal phenomena, however, results did support a relationship between derived relational responding and verbal intelligence. Additionally, results indicated a significant relationship between experiential avoidance and worry. Future research should clarify the relationship among the three primary variables of interest, improve measurement of these variables, be more sensitive to external validity, and promote the study of acceptance-based treatments that target experiential avoidance. digital.library.unt.edu/ark:/67531/metadc6069/
An exploration of the relationships among teacher efficacy, collective teacher efficacy, and teacher demographic characteristics in conservative Christian schools.
The purpose of this study was to determine whether teachers' perceptions of self-efficacy and collective teacher efficacy are interrelated and how these two constructs may be impacted by teacher demographic characteristics, such as educational level, grade level taught, and number of years of teaching experience. This study focused entirely on the interrelationships of teacher efficacy and collective teacher efficacy in three suburban, conservative Christian schools in north Texas. Specifically, the demographic characteristics of age, gender, ethnicity, particular school campus, number of years teaching, number of years teaching at the current school, highest degree received, type of teacher certification, certification grade level and subject area, grade level taught, and particular subject taught were studied for the non-random, convenience sample of 216 kindergarten through twelfth grade teachers. A correlational analysis of teacher efficacy and collective teacher efficacy yielded a Pearson r of .35 at a statistically significant level (p < .01); combining these two variables with teacher demographic variables in multiple regression analyses confirmed the relationship between teachers' perceptions of teacher efficacy and collective efficacy at a statistically significant level (p < .001). A review of the squared structure coefficients in the first multiple regression analysis (R2 = .284, p < .001) showed that individual teachers' perceptions of collective teacher efficacy explained the largest amount (43%) of the variance in teacher efficacy, followed by years of teaching experience (17%) and number of years of teaching at the current school (14%). A review of the squared structure coefficients in the second multiple regression analysis (R2 = .395, p < .001) indicated that individual teachers' perceptions of teacher efficacy explained the largest amount of variance in collective teacher efficacy (31%), followed the elementary teacher variable (22%) and particular school (19%). digital.library.unt.edu/ark:/67531/metadc5376/
An Exploration of the Titrating-Delay Match-to-Sample Procedure with Pigeons
The delayed matching‐to‐sample (DMTS) procedure involves the insertion of a delay between the offset of a sample stimulus and the onset of an array of comparison stimuli; one of which is designated as the “correct” match for the sample on each trial. The procedure has served as the base preparation in which the effects of environmental variables on short‐term remembering and is, in many ways, responsible for a refined understanding of the phenomenon. Despite its utility, however, there are a few problems with the DMTS procedure – first, the procedure doesn’t adjust for individual differences and second, the conventional dependent measure, percent of correct trials, is not as sensitive as one might like. The titrating-delay matching to sample (TDMTS) procedure is a variant of the DMTS procedure in which the delays between sample and comparison are adjusted as a function of the subject’s performance. Stable measures of adjusted delay are not only sensitive measures of the performance of interest but they are also automatically tuned to differences across individuals. The study reported here continues our efforts to understand the dynamics of the TDMTS procedure so that it can be used to ask important questions related to short‐term remembering. digital.library.unt.edu/ark:/67531/metadc103316/
Exploration of Visual, Acoustic, and Physiological Modalities to Complement Linguistic Representations for Sentiment Analysis
Access: Use of this item is restricted to the UNT Community.
This research is concerned with the identification of sentiment in multimodal content. This is of particular interest given the increasing presence of subjective multimodal content on the web and other sources, which contains a rich and vast source of people's opinions, feelings, and experiences. Despite the need for tools that can identify opinions in the presence of diverse modalities, most of current methods for sentiment analysis are designed for textual data only, and few attempts have been made to address this problem. The dissertation investigates techniques for augmenting linguistic representations with acoustic, visual, and physiological features. The potential benefits of using these modalities include linguistic disambiguation, visual grounding, and the integration of information about people's internal states. The main goal of this work is to build computational resources and tools that allow sentiment analysis to be applied to multimodal data. This thesis makes three important contributions. First, it shows that modalities such as audio, video, and physiological data can be successfully used to improve existing linguistic representations for sentiment analysis. We present a method that integrates linguistic features with features extracted from these modalities. Features are derived from verbal statements, audiovisual recordings, thermal recordings, and physiological sensors signals. The resulting multimodal sentiment analysis system is shown to significantly outperform the use of language alone. Using this system, we were able to predict the sentiment expressed in video reviews and also the sentiment experienced by viewers while exposed to emotionally loaded content. Second, the thesis provides evidence of the portability of the developed strategies to other affect recognition problems. We provided support for this by studying the deception detection problem. Third, this thesis contributes several multimodal datasets that will enable further research in sentiment and deception detection. digital.library.unt.edu/ark:/67531/metadc699996/
An exploration study of the relationship between effectiveness of filial therapy training groups and group cohesion.
This study examined the relationship of group cohesion among heterogeneous and homogeneous groups on individual treatment outcome of child-parent relationship therapy (CPRT). CPRT is a filial therapy model that targets the parent-child relationship as a means for preventing or improving child and/or family problems. This study included 30 parents or caregivers from 9 groups which met for 10 sessions. Participants qualified for this study if their groups ended with at least 3 group members and 2 leaders, all pretest and posttest data on their child between the ages of 2-11 was completed, and if they attended at least 6 of the 10 sessions. Correlation coefficients, t-tests, and effect sizes were calculated. Results demonstrated no statistically significant differences between pretests and posttests on the Child Behavior Checklist (CBCL) for all 30 participants; however, differences in measured effect (η2) between children identified with borderline and clinical behavior problems and children with normal behavior problems suggest that CPRT is more effective among children who demonstrate significant behavior problems. Perceived and observed group cohesion measurements demonstrated no significant difference at the individual outcome level. This finding suggests that group cohesion may not be related to individual outcome. Although there was no significant relationship between group cohesion and individual outcome for this study, results of the group measurements regarding engagement and group cohesiveness, coupled with previous studies on CPRT effectiveness, suggest that CPRT should be utilized in homogeneous groups. digital.library.unt.edu/ark:/67531/metadc9832/
Exploration through Materials and the Transformation of the Commonplace
The challenge of this project was to present subject matter in a way that did not seem common to the viewer. With this goal in mind, I aimed to switch the traditional roles of material and form in order to aesthetically elevate the commonplace. For my proposed project I combined traditional sculptural materials and processes with commonplace subject matter. I took a chance at the beginning of this project by making something that I had been joking about until I realized that this might be an interesting piece. From this point on I made a conscious effort to make whatever popped in my head. Although I am not a literary person, it seems that with this body of work I backed into what I might call "ironical metaphor." digital.library.unt.edu/ark:/67531/metadc5825/

Explorations with optically active, cage-annulated crown ethers.
A variety of optically active macrocyclic crown ethers that serve as "host" systems that are capable of differentiating between enantiomeric "guest" molecules during host-guest complexation have been prepared via incorporation of chiral elements into the crown ring skeleton. The ability of these crown ethers to recognize the enantiomers of guest salts, i.e., (+) a-methyl benzylamine and to transport them enantioselectively in W-tube transport experiments were studied. The ability of these crown ethers to perform as chiral catalysts in an enantioselective Michael addition was studied. The extent of asymmetric induction, expressed in terms of the enantiomeric excess (%ee), was monitored by measuring the optical rotation of the product and comparing to the literature value. digital.library.unt.edu/ark:/67531/metadc4207/
Explorations with Polycarbocyclic Cage Compounds
A variety of novel cage-functionalized pyridyl containing crown ethers have been prepared for use in selective alkali metal complexation studies. A highly preorganized, cage-functionalized cryptand also has been designed and has been synthesized for use as a selective Li+ complexant. The alkali metal picrate extraction profiles of these cage-functionalized crown ethers also have been studied. Novel cage-functionalized diazacrown ethers have been prepared for selective alkali metal complexation studies. Alkali metal picrate extraction experiments have been performed by using this new class of synthetic ionophores to investigate the effects of cage-annulation and the influence of N-pivot lariat sidearms upon their resulting complexation properties. Novel pyridyl containing calix[4]arene receptors were prepared. Analysis of their respective 1H NMR and 13C NMR spectra suggests that calix[4]arene moieties in the ligand occupy the cone conformation. The complexation properties of these host molecules were estimated by performing a series of alkali metal picrate extraction experiments. An optically active cage-functionalized crown ether which contains a binaphthyl moiety as the chiral unit was prepared. The ability of the resulting optically active crown ether to distinguish between enantiomers of guest ammonium ions (i.e., phenylethylamonium and phenylglycinate salts) in transport experiments was investigated. Hexacyclo[11.2.1.02,12.05,10.05,15.010,14]hexadeca-6,8-diene-4,11-dione was prepared from hexacyclo[7.4.2.01,9.03,7.04,14.06,15] pentadeca-10,12-diene-2,8-dione. Unanticipated but remarkable acid and base promoted rearrangements of this new cage dione to novel polycyclic systems were observed and subsequently were investigated. The structures of the new systems thereby obtained were determined unequivocally by application of X-ray crystallographic methods. It is noteworthy that the reactions reported herein each provide the corresponding rearranged product in high yield in a single synthetic step. Pi-facial and regioselectivity in the thermal Diels-Alder cycloaddition between hexacyclo[11.2.1.02,12.05,10.05,15.010,14]hexadeca-6,8-diene- 4,11-dione and ethyl propiolate have been explored. This reaction proceeds via stereospecific approach of the dienophile toward the syn face of the diene p -system. However, [4+2]cycloaddition proceeds with only modest proximal/distal regioselectivity. The structure of the minor reaction product was established unequivocally via application of X-ray crystallographic techniques. digital.library.unt.edu/ark:/67531/metadc2218/

Exploratory Analysis of Social E-health Behavior
Extant literature has documented well that people seek health information via the internet as patients and consumers. Much less, however, is known about interaction and creation behaviors in the development of new online health information and knowledge. More specifically, generalizable sociodemographic data on who engages in this online health behavior via social media is lacking in the sociological literature. The term “social e-health” is introduced to emphasize the difference between seeking behaviors and interaction and creation behaviors. A 2010 dataset of a large nationally representative and randomly sampled telephone survey made freely available from the Pew Research Center is used to examine social e-health behavior according to respondents’ sociodemographics. The dependent variable of social e-health behavior is measured by 13 survey questions from the survey. Gender, race, ethnicity, age, education, and income are used as independent variables. Logistic regression analysis was used to determine the odds of engagement in social e-health behavior based on the sociodemographic predictors. The social determinants of health and digital divide frameworks are used to help explain why socioeconomic variances exist in social e-health behavior. The findings of the current study suggest that predictable sociodemographic patterns along the dimensions of gender, race, age, education, and income exist for those who report engaging in social e-health behavior. This study is important because it underscores the fact that engagement in social e-health behavior is differentially distributed in the general U.S. population according to patterned sociodemographics. digital.library.unt.edu/ark:/67531/metadc500111/
