Creator: Iyer, Pramod P
Description: Brands are intangible assets that provide companies with the potential to extract higher rents or prices from customers. However, only few organizations are able to build and sustain brands over a long period of time. Brand management capability - the organization's ability to build and sustain brands becomes important for achieving sustainable competitive advantage. Despite the importance of brand management capability to organizations, majority of the brand management literature has primarily focused on the consumer perspective of brands. This gap in knowledge about the components of brand management capability impedes firms from replicating brand successes, and makes them reliant on brand managers. More recently, there have been multiple calls in literature to identify marketing-related organizational capabilities, which can provide organizations with a sustainable competitive advantage. The focus on developing marketing-based capabilities comes at a time when marketing is losing its influence in organizations. To this end, the current dissertation uses organizational capability theory and literature on brand management to identify the primary resource (intellectual capital comprising of structural, human, and relational capital), organizational culture type (clan, adhocracy, hierarchy, and market), and processes (strategic brand management, internal branding, and market information processes comprising of information acquisition, information transmission, conceptual utilization, and ...

Can Imagination Travel the Distance?  Investigating the Role of Psychological Distance and Construal Level in Consumers' Elaborative Approach

Can Imagination Travel the Distance? Investigating the Role of Psychological Distance and Construal Level in Consumers' Elaborative Approach

Access: Use of this item is restricted to the UNT Community.

Creator: Dadzie, Charlene Ama
Description: Much of consumer behavior research focuses on how consumers process and evaluate information to make current decision. In contrast, many consumer choices ares are underpinned by the need to make choices that incorporate the past or future, other places, other people and other situations that are seemingly hypothetical. The imagination provides the chief means by which consumers are able to traverse this psychological distance. Construal Level Theory (CLT) explains how individuals are able to plan for the future, consider the perspective of another individual and even consider situations that are counter to reality. Construal mindsets are enacted when people form mental representations of distant objects, people, or places. In abstract construal mindsets, individuals think generally, in terms of global features of an object, person, or situation. On the other hand, concrete construal mindsets center around the detailed aspects of an object, person, or situation. These two different construal mindsets serve to help people cope with the uncertainty of the future. This is because abstract cosntruals are more likely than concrete construals to remain unchanged as distance from a future object, person, or place reduces. A number of consumer behavior settings require the use of the imagination. Sticking to a weight ...

Las Cantigas de Santa Maria: Thirteenth-Century Popular Culture and Acts of Subversion

Las Cantigas de Santa Maria: Thirteenth-Century Popular Culture and Acts of Subversion

Date: August 2016
Creator: Coats, Jerry Brian
Description: Across medieval Europe, the pilgrimage route to Santiago de Compostela in Spain traced a lattice web of popular culture. From the lowest peasant to the greatest king and churchmen, the devout walked pathways that created an economy and contributed to a social and political climate of change. Central to this impulse of piety and wanderlust was the veneration of the Virgin Mary. She was, however, not the iconic Mother of the New Testament whose character, actions, and very name are nearly absent from that first-century compilation of texts. As characterized in the words of popular songs and tales, the mariales, she was a robust saint who performed acts of healing that exceeded those miracles of Jesus described in the Bible. Unafraid and authoritative, she confronted demons and provided judgement that reached beyond the understanding and mercy of medieval codes of law. Holding out the promise of protection from physical and spiritual harm, she attracted denizens of admirers who included poets, minstrels, and troubadours like Nigel of Canterbury, John of Garland, Gonzalo de Berceo, and Gautier de Coinci. They popularized her cult across Europe; pilgrims sang their songs and celebrated the new attributes of Mary. This dissertation uses the greatest collection ...

Child Parent Relationship Therapy: A Program Evaluation

Child Parent Relationship Therapy: A Program Evaluation

Date: August 2016
Creator: Ley, Tiffany Andresen
Description: For the past 40 years, one southwestern US university counseling program has sponsored two mental health training clinics in which master's and doctoral level students have learned to provide child parent relationship therapy (CPRT) services to community parents. In their training, students learn about the positive effects of CPRT, particularly on parental stress. To date, however, no program evaluation has been conducted at these clinics focusing specifically on parental stress outcomes after the completion of CPRT or to determine the demographics and characteristics of parents who pursue CPRT. The purpose of this study was to conduct such an evaluation of archival data spanning 7 years. Participants were 129 parents (70% female, 30% male; 80% Caucasian, 35% Hispanic/ Latino, 6% African American, and 4% Asian; 62% married, 9% separated, 16% divorced). Results from a t-test indicated a statistically significant decrease in self-reported parental stress, with a moderate effect size. Multiple regression revealed that women and those who attended with a co-parent reported greater stress reduction. This study confirmed the benefit of CPRT, provided by counselors-in-training, on reducing parental stress and indicated clientele for which and conditions in which those benefits might be optimized.

Clenching the Fists of Dissent: Political Unrest, Repression, and the Evolution to Civil War

Clenching the Fists of Dissent: Political Unrest, Repression, and the Evolution to Civil War

Date: August 2016
Creator: Backstrom, Jeremy R
Description: Previous scholarship has long concentrated on the behaviors of belligerents during regime-dissident interactions. While much of the progress in the literature concentrated on the micro-level processes of this relationship, little research has focused on providing a theoretical reasoning on why belligerents choose to act in a particular manner. This project attempts to open the black box of decision making for regimes and dissidents during regime-dissident interactions in order to provide a theoretical justification for the behaviors of the belligerents involved. Moreover, this project argues that there is a relationship between the lower level events of political violence and civil war as the events at earlier stages of the conflict influence the possible outcome of civil conflict. Regimes and dissidents alike are strategic actors who conduct themselves in a manner to ensure their survival while concurrently attempting to succeed at achieving their respective goals. Although all authoritarian regimes are similar in their differences to democracies, there are significant differences between the regimes, which influence the decision making of the regime leader to ensure the survival of the political institution. In addition to influencing the decision calculus of the regimes, the behavior of the regimes impacts the probability of civil war at ...

Coaching Efficacy Beliefs and Transformational Leadership Behaviors: Their Ability to Predict Motivational Climate

Coaching Efficacy Beliefs and Transformational Leadership Behaviors: Their Ability to Predict Motivational Climate

Date: August 2016
Creator: Runge, Michael J
Description: This study investigated the relationship between belief in coaching abilities (coaching efficacy beliefs, CEB), transformational leadership behaviors (TLB), and motivational climate development of current strength and conditioning coaches working with high school level athletes. The measures used were the coaching efficacy scale for high school teams (CES II-HST, Myers et al.,2000), the differentiated transformational leadership inventory (DTLI, Callow et al., 2009), and the patterns of adaptive learning scales (PALS, Midgley et al., 2000). It was hypothesized that CEB and TLB would influence motivational climate development, while coaches' background characteristics would correlate with CEB, TLB, and motivational climate development. The 60 coaches who participated reported an average of thirteen (SD=8) years of experience and 51 were Certified Strength and Conditioning Specialists. Coaches reported high efficacy, frequent use of TLB, and development of a moderately high task- and somewhat ego-involving motivational climate. Correlations between demographic variables and CEB, TLB, and motivational climate development revealed three significant relationships: years of experience with CEB, and professional development activities and athlete to coach ratio with ego-involving climate development. CEB and TLB had a strong positive correlation. Two regression analyses were conducted to determine if the outcomes of the CEB and TLB measures predicted motivational climate ...

A Comparative Analysis of Haydn's Horn Concerto and Trumpet Concerto

A Comparative Analysis of Haydn's Horn Concerto and Trumpet Concerto

Date: August 2016
Creator: Adamson, Daniel Richard
Description: Among the existing solo instrumental concertos of Joseph Haydn's oeuvre are two concertos for brass instruments. These are the Horn Concerto in D Major (Hob. VIId: 3) and Trumpet Concerto in E-flat Major (Hob. VIIe: 1). In addition to their standing as the only two concertos for solo brass instruments written by Haydn in existence, the two concertos provide a unique opportunity for insight into the history of the concerto genre and Haydn's change in compositional style. This is because of their chronological position within Haydn's oeuvre; the Horn Concerto was composed in 1762 during the early years of Haydn's employment with the Esterházy family and the Trumpet Concerto in 1796 as the last known concerto written by Haydn. Significant changes had occurred during that thirty four year time-span, not only in Haydn's life, but also within the field of music. This dissertation examines some of these changes and provides a comparative analysis of these two pieces. More specifically, it employs Schenkerian analysis of the voice-leading and structure of both concertos to examine the transformation in Haydn's compositional style and show the evolution of concerto form. This evolution in style between the Horn Concerto and Trumpet Concerto is most prominently ...

A Comparison of Treatments for Posttraumatic Stress Disorder Symptoms: Memory Specificity Training (MeST) and Cognitive Processing Therapy (CPT)

A Comparison of Treatments for Posttraumatic Stress Disorder Symptoms: Memory Specificity Training (MeST) and Cognitive Processing Therapy (CPT)

Date: August 2016
Creator: Maxwell, Kendal Lynn
Description: The effectiveness of memory specificity training (MeST) was compared with standard cognitive processing therapy (CPT) in treatment of individuals with posttraumatic stress disorder. Eighteen adults aged 18-36 were randomly assigned to the MeST intervention (n = 9) or to the active control group (n = 9) of CPT. Both treatments were administered in group format across 6 weeks. MeST consisted of 6 weekly sessions, while CPT consisted of 12 biweekly sessions. The trial was undertaken in the Psychology Clinic of the University of North Texas, with randomization to conditions accomplished via computer random number generator. The primary outcome measure was change in PTSD symptoms post-treatment from baseline. Sixteen individuals (13 women and 3 men; MeST n = 8 and CPT n = 8) completed treatment and their data was analyzed. MeST significantly decreased PTSD symptomology at post-treatment and these results were maintained at 3 months post-treatment. MeST was found to be as effective as the established CPT intervention at reducing PTSD symptomology. Both MeST and CPT significantly increased participants' ability to specify memories upon retrieval at post-treatment, with results maintained at follow-up. There were no significant effects of MeST or CPT in ability to increase overall controlled cognitive processing at ...

Composing Symbolism's Musicality of Language in fin-de-siècle France

Composing Symbolism's Musicality of Language in fin-de-siècle France

Date: August 2016
Creator: Varvir Coe, Megan E
Description: In this dissertation, I explore the musical prosody of the literary symbolists and the influence of this prosody on fin-de-siècle French music. Contrary to previous categorizations of music as symbolist based on a characteristic "sound," I argue that symbolist aesthetics demonstrably influenced musical construction and reception. My scholarship reveals that symbolist musical works across genres share an approach to composition rooted in the symbolist concept of musicality of language, a concept that shapes this music on sonic, structural, and conceptual levels. I investigate the musical responses of four different composers to a single symbolist text, Oscar Wilde's one-act play Salomé, written in French in 1891, as case studies in order to elucidate how a symbolist musicality of language informed their creation, performance, and critical reception. The musical works evaluated as case studies are Antoine Mariotte's Salomé, Richard Strauss's Salomé, Aleksandr Glazunov's Introduction et La Danse de Salomée, and Florent Schmitt's La Tragédie de Salomé. Recognition of symbolist influence on composition, and, in the case of works for the stage, on production and performance expands the repertory of music we can view critically through the lens of symbolism, developing not only our understanding of music's role in this difficult and often ...

Compostable Soy-Based Polyurethane Foam with Kenaf Core Modifiers

Compostable Soy-Based Polyurethane Foam with Kenaf Core Modifiers

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Hoyt, Zachary
Description: Building waste and disposable packaging are a major component in today's landfills. Most of these are structural or thermally insulative polymer foams that do not degrade over a long period of time. Currently, there is a push to replace these foams with thermoplastic or biodegradable foams that can either be recycled or composted. We propose the use of compostable soy-based polyurethane foams (PU) with kenaf core modifiers that will offer the desired properties with the ability to choose responsible end-of-life decisions. The effect of fillers is a critical parameter in investigating the thermal and mechanical properties along with its effect on biodegradability. In this work, foams with 5%, 10%, and 15% kenaf core content were created. Two manufacturing approaches were used: the free foaming used by spray techniques and the constrained expansion complementary to a mold cavity. Structure-property relations were examined using differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), thermal conductivity, compression values, scanning electron microscopy (SEM), x-ray micro-computed tomography (micro-CT), and automated multiunit composting system (AMCS). The results show that mechanical properties are reduced with the introduction of kenaf core reinforcement while thermal conductivity and biodegradability display a noticeable improvement. This shows that in application properties can be ...

Conceptual Framework for the Development of an Air Quality Monitoring Station in Denton, Texas

Date: August 2016
Creator: Boling, Robyn
Description: Denton, Texas consistently reaches ozone nonattainment levels. This has led to a large focus of air pollution monitoring efforts in the region, with long-range transport being explored as a key contributor. For this study, the University of North Texas Discovery Park campus was chosen as a prospective location for an extensive air quality monitoring station. Sixteen years of ozone and meteorological data for five state-run monitoring sites within a 25 mile radius, including the nearest Denton Airport site, was gathered from TCEQ online database for the month of April for the years 2000 to 2015. The data was analyzed to show a historical, regional perspective of ozone near the proposed site. The maximum ozone concentration measured at the Denton Airport location over the 16 year period was measured at 96 ppb in 2001. Experimental ozone and meteorological measurements were collected at the Discovery Park location from March 26 to April 3 and April 8 to April, 2016 and compared to the Denton Airport monitoring site. A time lag in ozone trends and an increase in peak ozone concentrations at the proposed location were observed at the proposed site in comparison to the Denton Airport site. Historical and experimental meteorological data ...

Confronting the Enemy Within: An In-Depth Study on Psychological Self-Handicapping among Collegiate Musicians

Date: August 2016
Creator: Flowers, Michelle Clements
Description: Self-handicapping is a psychological behavior people engage in to protect their self-image, project a desired image to others, and to augment feelings of success and achievement. Self-handicapping occurs when individuals have a positive but uncertain self-image about their competence in an arena of life fundamental to their self-identity. Musicians have been underrepresented in self-handicapping studies; yet the very competitive nature of their education and craft, the strong identification musicians have as musicians, and the frequent challenges during all phases of development to their abilities would suggest they are extremely vulnerable to developing self-handicaps. This dissertation discusses the theoretical components of self-handicapping, the personality traits typically exhibited by high self-handicappers, causes, types, and possible motivations for self-handicapping, short and long term effects of the behavior, and the implications these concepts have to the musician community. In addition, it contains the results of an extensive survey of musicians which examines self-handicapping tendencies, depression, imposter phenomenon, and self-esteem ratings to determine 1) if musicians self-handicap, 2) how the four constructs are related to each other within the musician population, 3) if other factors concerning musicians and self-handicapping are related, 4) areas for future research. Several significant relationships involving the four constructs tested, as ...

Constructional Fear Treatment for Dogs in Shelters

Constructional Fear Treatment for Dogs in Shelters

Date: August 2016
Creator: Katz, Morgan
Description: Of the approximately 3.9 million dogs that enter US animal shelters each year, many exhibit behaviors related to fear, which can affect their likelihood of adoption. Current dog training procedures to treat fear include counterconditioning and desensitization, which can often take months or years to show any behavior change and do not teach specific behaviors aimed to increase the dog's chance of being adopted. The current study used a negative reinforcement shaping procedure to teach fearful dogs to approach and and interact with people. The results showed that constructional fear treatment increased the amount of time the dog spent at the front of the kennel, and increased sniffing, tail wagging, and accepting petting for all 3 participants.

Context Matters: How Feminist Movements Magnify Feminist Opinion of Progressive Policies in South America

Context Matters: How Feminist Movements Magnify Feminist Opinion of Progressive Policies in South America

Date: August 2016
Creator: Ferris, Rachel E
Description: What explains the inconsistency of female empowerment in South America, despite high levels of institutional inclusion? Generally, the social sciences tend to lean on the tenets of liberal feminism in order to measure the development of gender-inclusive policy changes; however, their findings indicate that higher levels of institutional inclusion does not necessarily translate into the empowerment of women as a group. Further, within political science, there is little research addressing the relationship between feminist movements and the feminist opinion of individuals within a state. I argue that strong feminist social movements provide a context in which feminist opinion is magnified, and where individuals will be more likely to support progressive policy changes. Using questions from the World Values Survey, I operationalize progressive policies as the Justifiability of Abortion. My primary independent variables are the presence feminist movements and the presence of feminist opinion, which is measured by support for female sexual freedom. After using a multilevel mixed-effects linear regression, I find support for my hypotheses, indicating that feminist opinion is magnified by the presence of feminist movements.

Contextualizing History Curriculum: A Qualitative Case Study in Balochistan Pakistan

Contextualizing History Curriculum: A Qualitative Case Study in Balochistan Pakistan

Date: August 2016
Creator: Khan, Gulab
Description: The purpose of the study was to evaluate Pakistan's national history curriculum in the post 18th constitutional amendment scenario. The amendment bequeathed the responsibility of education, including curriculum development, to the provinces. This study sought input from educators on ways the national curriculum currently addresses local needs and requirements as well as considerations for any potential changes or improvements. Traditionally, history curriculum has been used mainly for social identity formation and ideological indoctrination; current scholarship on history education has now also included national identity formation. Additionally, scholarship has begun to analyze possible purposes behind social identity formation, whether used negatively or positively. This study, which took place in Balochistan, Pakistan, used a qualitative case study approach. A provincial level conference was convened as a context and data source that involved 28 educators including teachers, teacher educators, curriculum experts, and policy actors as participants in the study. The texts of five representative educators engaged in the conference dialogue was selected for analysis. Discourse analysis was the methodology used to arrive at findings of the study. The study yielded several interesting findings that give insight about the national history curriculum of Pakistan and future curriculum practices of the Balochistan province. According to ...

Cooperative Strategy and Sources of Knowledge Integration Capability and Innovation: A Relational View

Cooperative Strategy and Sources of Knowledge Integration Capability and Innovation: A Relational View

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Acharya, Chandan
Description: Faced with the challenges to addressing the novelties of the changing business environments (e.g., new customer requirement, changes in customers taste and preferences, the introduction of new products or services by competitors), organizations seek to build collaboration among their employees who possess complementary knowledge. Integrating complementary knowledge enhances employees' ability to address environmental challenges and foster innovation. Despite the importance of knowledge integration for innovation, integration of such knowledge becomes difficult when employees lack a shared understanding of knowledge, and when the knowledge is newly generated. Because new knowledge is tacit in nature and highly personal to a particular individual, it is difficult to articulate, making knowledge integration (KI) an arduous task. Lack of shared understanding, the presence of new knowledge, and lack of common interests in employees creates three types of knowledge boundaries – syntactic (information processing) boundaries, semantic (interpretive) boundaries, and pragmatic (political) boundaries. The presence of knowledge boundaries makes it difficult for employees to share and access their knowledge with each other. To overcome the challenges related to the knowledge boundaries, employees use boundary-spanning objects, which are common lexicons, common meaning, and common interests, to share and access their knowledge across the boundaries. Although prior studies have ...

Costs and Benefits of Mind Wandering in a Technological Setting: Findings and Implications

Costs and Benefits of Mind Wandering in a Technological Setting: Findings and Implications

Date: August 2016
Creator: Sullivan, Yulia
Description: The central purpose of this dissertation is to develop and test a theoretical model of mind wandering in a technological setting by integrating the emerging work and theory on mind wandering—a shift of attention from the primary task to the processing of internal goals. This dissertation is intended to advance our understanding on the costs and benefits of mind wandering in information systems (IS) research and in turn, contribute to the literature of cognitive IS research. Understanding the consequences of mind wandering in a technological setting is imperative because mind wandering plays a vital role in influencing various outcomes associated with technology use and/or technology learning, such as technology anxiety, software self-efficacy, and task performance. This dissertation is composed of three essays which examine the determinants and consequences of mind wandering and focus of attention on a number of emotional and cognitive outcomes. A multi-method approach (i.e., online survey and laboratory experiment) across three essays is used to test the research models. Essay 1 focuses on developing the measurement items and estimating the impact of mind wandering on users' emotional outcomes (i.e., technology anxiety and users' satisfaction). Drawing upon the content regulation hypothesis of mind wandering, the content of thoughts ...

"Counting Out The Harvest"

"Counting Out The Harvest"

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Lischau, Carol
Description: "Counting Out The Harvest" is a collection of poems exploring intimate encounters. The poems reflect on encounters with memories, family, and the natural and cosmic worlds. In one of the poems, "Red-Throated Anole," the speaker works desperately to save a small dying lizard. In "Ice Storm, Post-Divorce," the speaker attempts to decipher a cluster of ladybugs taking refuge in her room. In the title poem, a couple wonders patiently if their crop will eventually grow. In each of these poems there is a present longing for the construction of a meaningful identity by means of the encounter, but the intersection between speaker and world falls short of satisfaction, whether the faultiness lies in the body's inability to find full sustenance, or in the ever-changing fluidity of memory to find stability. But the poems progress from pressing against this difficulty toward finding a contented resignation to the world's cyclical order. The final line of the manuscript, "disrobe a layer to begin again," indicates an arrival at satisfaction, which is found ultimately in continuation.

Creator: Alshara, Mohammed Ali
Description: Mobile banking services have changed the design and delivery of financial services and the whole banking sector. Financial service companies employ mobile banking applications as new alternative channels to increase customers' convenience and to reduce costs and maintain profitability. The primary focus of this study was to explore the Saudi bank customers' perceptions about the adoption of mobile banking applications and to test the relationships between the factors that influence mobile banking adoption as independent variables and the action to adopt them as the dependent variable. Saudi customers' perceptions were tested based on the extended versions of IDT, TAM and other diffusion of innovation theories and frameworks to generate a model of constructs that can be used to study the use and the adoption of mobile technology by users. Koenig-Lewis, Palmer, & Moll's (2010) model was used to test its constructs of (1) perceived usefulness, (2) perceived ease of use, (3) perceived compatibility, (4) perceived credibility, (5) perceived trust, (6) perceived risk, and (7) perceived cost, and these were the independent variables in current study. This study revealed a high level of adoption that 82.7% of Saudis had adopted mobile banking applications. Also, the findings of this study identified a ...

Creator: Quan, Daniel L
Description: With an increasing population suffering from obesity or Diabetes Mellitus (DM), it is more pertinent than ever to understand how physiological changes impact cellular processes. Patients with DM often suffer from obesity, hyperglycemia, altered fatty acids that contribute to vascular dysfunction, and increased risk to ischemia. Caenorhabditis elegans is a model system used to study the conserved insulin signaling pathway, cellular responses in whole organisms and the impact a glucose diet has on oxygen deprivation (anoxia) responses. RNA-sequencing (RNA-Seq) was used to analyze the expression of genes in the anoxia sensitive populations of N2 (wild-type) fed glucose and hyl-2(tm2031), a mutant with altered ceramide metabolism. Comparison of the altered transcripts in the anoxia sensitive populations revealed 199 common transcripts- 192 upregulated and 7 downregulated. One of the gene families that have altered expression in the anoxia sensitive populations encode for Cytochrome P450 (CYP). CYPs are located both in the mitochondria and endoplasmic reticulum (ER), but the CYPs of interest are all predicted to be mainly subcellularly localized to the ER. Here, I determined that knock-down of specific cyp genes, using RNA interference (RNAi), increased anoxia survival in N2 animals fed a standard diet. Anoxia sensitivity of the hyl-2(tm2031) animals was ...

Data-Driven Decision-Making Framework for Large-Scale Dynamical Systems under Uncertainty

Data-Driven Decision-Making Framework for Large-Scale Dynamical Systems under Uncertainty

Access: Use of this item is restricted to the UNT Community.
Date: August 2016
Creator: Xie, Junfei
Description: Managing large-scale dynamical systems (e.g., transportation systems, complex information systems, and power networks, etc.) in real-time is very challenging considering their complicated system dynamics, intricate network interactions, large scale, and especially the existence of various uncertainties. To address this issue, intelligent techniques which can quickly design decision-making strategies that are robust to uncertainties are needed. This dissertation aims to conquer these challenges by exploring a data-driven decision-making framework, which leverages big-data techniques and scalable uncertainty evaluation approaches to quickly solve optimal control problems. In particular, following techniques have been developed along this direction: 1) system modeling approaches to simplify the system analysis and design procedures for multiple applications; 2) effective simulation and analytical based approaches to efficiently evaluate system performance and design control strategies under uncertainty; and 3) big-data techniques that allow some computations of control strategies to be completed offline. These techniques and tools for analysis, design and control contribute to a wide range of applications including air traffic flow management, complex information systems, and airborne networks.
