2D and 3D Fabrication Devices: Can They Improve Spatial Reasoning Skills in Children?

Description: The purpose of this study is to evaluate the potential benefit of two hours of activities involving 2D and 3D fabricators on the spatial reasoning skills of children in Grades 4 and 5, ages 9 to 10, from a private school in Southeast Texas. Can the introduction to hands-on activities with products created with these devices and learning about how these devices operate improve spatial reasoning skills? The research also evaluates the use of the Shapes Test as a valid measure of the spatial reasoning skills of children. The Cube Design and Spatial Memory subtests of the UNIT (Universal Nonverbal Intelligence Tests) were used for evaluating the spatial reasoning skills of the participants, based on their respected validity, along with a Shapes Test that is in development. Discussion regarding gender, language, and experiential theories of spatial reasoning skill development are included in the literature review.

Accuracy of Partner Perception and Relationship Satisfaction: Investigating Masturbatory Habits

Description: An individual's perceptions of various aspects of one's romantic relationship (irrespective of whether or not the perceptions align with reality) often play a critical role in romantic relationship satisfaction. Research has demonstrated that the accuracy of an individual's perception of his or her partner is generally positively related to the individual's romantic relationship satisfaction. However, when perceiving negative or conflictual messages from a partner, an individual's accuracy of perception is negatively associated with his or her romantic relationship satisfaction. Researchers have suggested that poor accuracy in perceiving negative messages might diffuse the negative intention in a way that is less impactful to the relationship. The present study was designed to investigate accuracy in the perception of sexual topics, specifically masturbatory habits. A sample of 93 married couples (186 individuals) responded to questions about (a) their own masturbatory behaviors and (b) their perception of their partners' masturbatory behaviors to determine the accuracy of each partner's perception of his or her partner. The association between accuracy and romantic and sexual relationship satisfaction was explored, along with one potential moderating variable: attitudes toward masturbation. Perceived reason for masturbating, perceived target of arousal during masturbation, and partner's actual reason for masturbating all positively predicted an individual's relationship satisfaction. Partner's actual openness about masturbatory behaviors moderated the association between accuracy of partner perception of openness about masturbation and both relationship and sexual satisfaction. When partners were more open about masturbation, accuracy was a stronger positive predictor of relationship and sexual satisfaction than when partners were less open about masturbation. Results, limitations, areas for future research, and clinical implications are discussed.

Art Education Policy: Interpretation and the Negotiation of Praxis

Description: This collective case study explores the confluence of educational policy and professional praxis by examining the ways art teachers in one public school district make decisions about creating and implementing curricula. Through various interpretations of one district's formal and informal expectations of art teachers, some of the complexities of standards, instruction, and assessment policies in public schools are described. The research shares how art teachers are influenced by local policy expectations by examining how five K-12 art teacher participants negotiate their ideological beliefs and practical knowledge within the professional context of their local setting, and presents an art teacher decision-making framework to conceptualize the influences for praxis and to organize analysis. Case study data include in-depth interview sessions, teaching observations, and district policy artifacts. Themes emerge in the findings through coding processes and constructivist grounded theory analysis methods. The research describes how participants interpret and negotiate expectations, finding curricular freedom and participation in public exhibition as central policy factors. Contributing the perspectives of art teachers to the literature of policy implementation and fine arts education, the study finds that balancing autonomy and mandates are primary sites for negotiating praxis and that informal expectations for student exhibition contribute to a culture of competition and teacher performance evaluations. The study presents implications for policy makers, administrators, and art educators while sharing possibilities for future research about policy expectations.

Associations Between Witnessing the Abuse of a Sibling in Childhood and Experiencing Trauma Related Symptoms in Adulthood

Description: Currently sibling research is burgeoning, yet there is virtually no literature regarding outcomes associated with witnessing the abuse of a sibling. The present study aimed to address this gap in the literature. A sample of 284 university students were surveyed regarding traumatic experiences in childhood and adulthood, the quality of childhood sibling relationships, and the experience of trauma symptoms in adulthood. Regression and moderation analyses were conducted to examine the relationship between witnessing the abuse of a sibling in childhood and trauma symptoms in adulthood and to assess whether sibling relationship quality moderates the association between sibling abuse and trauma symptomology. Results showed that witnessing the abuse of a sibling was associated with depression symptoms in the overall sample and for females reporting about a brother. Also, sibling conflict moderated the relationship between witnessed sibling abuse and externalization in sister-sister dyads. These associations should be considered in terms of the systemic abuse to which participants were exposed. Implications for clinical practice working with sibling-related victimization are discussed.

Attachment Insecurity, Emotion Regulation Difficulties, and Mindfulness Deficits in Personality Pathology

Description: A growing body of research has documented associations between personality disorders (PDs) and attachment disturbance, and yet, attachment disturbance does not necessarily guarantee the development of PD pathology. Thus, understanding the mechanisms mediating the relationship between attachment disturbance and PD pathology remains an open area of research. One area with sound theoretical and empirical evidence has shown that attachment disturbances are associated with emotion regulation difficulties, as well as maladaptive interpersonal patterns of behavior. However, the research conducted thus far has predominately focused on borderline personality disorder, at the exclusion of other PD domains, and also has not broadened the scope of research to include other relevant psychological processes that may clarify how personality pathology and attachment disturbance are interrelated. Using a large independent sample of college (n = 946) and community-based individuals (n = 271), the current study aimed to (1) examine how the Personality Inventory for DSM-5 (PID-5) PD trait domains would be differentially associated with maladaptive attachment processes and emotion regulation problems, and (2) explore whether deficits in mindfulness and emotion regulation mediated the relationship between disturbed attachment and PD trait domains. Findings suggested that the PID-5 PD trait domains have general and specific relations to attachment insecurity, impairments in emotion regulation, and decreased mindfulness. Overall, the current study suggests that improving emotion regulation skills and increasing dispositional mindfulness may limit the expression of pathological personality traits. Implications of these findings and directions for future research are discussed.

Attitudes about Caregiving: An Ethnicity by Generation Approach

Description: The goal of this project was to understand ethnic and generational differences in attitudes towards caregiving and expected burden while taking into consideration factors such as gender, generation, familism, and acculturation. One hundred and sixteen young adults (ages 18-25) and 93 middle-age adults (ages 38-62) were enrolled in the study. Participants included European Americans, African Americans, and Hispanics. Using moderation analysis, two hypotheses were investigated: 1) Ethnicity relates to attitudes towards caregiving, moderated by gender, generation, familism, and acculturation. 2) Ethnicity and expected burden relate to each other, moderated by gender, generation, familism, and acculturation. Familism emerged as a moderator in the relationship between ethnicity and expected burden. Results suggested that the strength of the relationship between being African American and expecting burden was less for those with moderate familism (R =.078), slightly higher for low familism (R = .176), and the highest for high familism (R= .261). Additional results indicated that the strength of the relationship between being Hispanic, as opposed to being European American, and expected burden, was higher for middle-aged adults (R =.23) when compared to young adults (R =.19). The current findings lend support to the recently established idea that familism is not protective against burden as it increases one's sense of obligation towards family (Knight & Sayegh, 2010).

Brand Management Capability and Brand Performance

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 instrument utilization), that constitute the brand management capability. This dissertation also examines the association among various components of brand management capability and brand performance. A survey-based technique was used to gather data from individuals responsible for managing brands. The data was analyzed using PLS-SEM. The results indicate that human capital, relational capital, market and hierarchy culture types, internal branding, strategic brand management, and instrument utilization are positively associated with brand performance. Structural capital, clan and adhocracy culture types, information acquisition, information transmission, and conceptual utilization are not associated with brand performance. From a research standpoint, this dissertation contributes to the ...

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

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 loss and or fitness plan, planning a vacation trip, saving for retirement and imagining what birthday gift a friend will enjoy all require imagining a psychologically distant state. Marketers generally seek to stimulate consumption by requiring consumers to imagine a consumption setting. This dissertation uses CLT to guide the hypotheses, as CLT explains how individuals deal with psychological distance by adopting a construal mindset. CLT explains differences in information processing associated with adopting a specific construal mindset and suggests how construal mindsets impact consumer information elaboration processes. This study will contribute to CLT by addressing an understudied be related area: ...

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

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 of these songs, Las Cantigas de Santa Maria compiled in the thirteenth century under the direction of Alfonso X, King of Castile and Leon, to construct the history of a lay piety movement deeply rooted in medieval popular culture. Making the transition from institutionalized, doctrinal saint to popular heroine, Mary becomes a subversive conduit through which culture moved from Latin poetry to vernacular verse and from the monasteries of scholasticism to the popular pathway of Wycliffite reform.

Child Parent Relationship Therapy: A Program Evaluation

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

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 later stages of the interaction. Conversely, dissidents also perform as strategic actors in an attempt to gain their preferred concessions and outcomes. Although their comprehension of the coercive capacity of a regime is limited, their knowledge of the repressive capacity of the regime provides them with the understanding of their future fate if they escalate to violence against the regime. This project is conducted using two theories on regime and dissident actions and responses, two large-N empirical analyses of regime and dissident behaviors during nonviolent and violent dissident campaigns from 1945-2006, and two historical case studies of Egypt and Syria ...

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

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 marked by a loosening of compositional constraints, including freer formal procedures, instrumentation, harmonic structures, and an increase in chromaticism (aided by the new chromatic abilities of the trumpet). This document provides an in-depth comparative analysis within an often overlooked genre of music and gives insight into changes in Haydn's compositional style and the concerto genre.

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

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 post-treatment or follow-up. No individual in either group reported any adverse effects during treatment or at 3 months follow-up. MeST appears to hold promise as an efficacious treatment option for PTSD. MeST was as effective as CPT in reducing symptoms of PTSD, but required only half the number of treatment sessions to accomplish these gains. Replication of these findings in larger samples is encouraged.

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

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 contradictory aesthetic philosophy but also our perception of fin-de-siècle musical culture in general.

A Conductor's Guide to Un-Yung La's Choral Music as Reflected in Easter Cantata

Description: Un-Yung La was one of the first Korean composers of Western style choral music who used Korean folk elements in his composers. According to Un-Yung La's musical theory, which he demonstrated in Easter Cantata. Korean-style melody and rhythm were created based on Korean traditional scales and he also used Western-style harmonization. He attempted a new Korean style of expression through Sikimsae technique in Korean traditional vocal music genres: Pansori and Sijo. The purpose of this paepr is to discuss traditional Korean performance elements related to melody, harmony, and rhythm as employed in La's Easter Cantata. The study will increase the knowledge of western conductors who wish to understand Korean folk music in preparation for performance of choral works such as La's Easter Cantata.

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

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 well as a significant difference between the self-handicapping behaviors of professional and amateur players were found.

Contextualizing History Curriculum: A Qualitative Case Study in Balochistan Pakistan

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 the selected educators, the national history curriculum of Pakistan has been unidimensional, based on Islamic ideology that embraces a religious national identity. The selected educators argued that the curriculum is unwelcoming to diversity, does not promote peace and equity, conceals truth, and hinders critical thinking. They found the national history curriculum non-representative of the local context of Balochistan province. In light of these findings, the selected educators proposed a history curriculum for Balochistan province that promotes peace, tolerance, equity, and respect for diversity, truth, and critical thinking. The participating educators saw a provincial/local focus as addressing many limitations of the ...

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

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 emphasized the importance of knowledge integration of various knowledge sources for innovations, examinations of what enhances KI capability of employees for organizational innovation remain limited. In addition, apart from Carlile, (2004) and Franco (2013), which are both case studies, other studies that examine the role of boundary spanning objects for knowledge integration are missing. The knowledge management literature also fails to measures (the success of common lexicons, common meaning, and common interests for achieving KI capability) boundary spanning objects. Therefore, in this study, new measurement items of boundary spanning objects and novelty are developed to test the hypotheses. A survey-based ...

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

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 are differentiated into two categories—technology-related thought (herein IT) and non-technology related thought (herein non-IT). The results show that whereas mind wandering (non-IT) is a major determinant of technology anxiety, focus of attention (IT) is the main predictor of users' satisfaction. Essay 2 focuses on the effect of mind wandering and focus of attention in the IS learning context. The study begins by exploring the hypotheses concerning the roles of executive functions (i.e., inhibition, switching, and working memory) and task complexity in influencing the occurrence of mind wandering and focus of attention, and in turn, cognitive outcomes (i.e., software self-efficacy and ...

Creating Musical Momentum: Textural and Timbral Sculpting with Intuitive Compositional Systems and Formal Design

Description: This dissertation explores the analysis and creation of compositions from the standpoint of texture and momentum. It is comprised of four chapters. The first presents a number of concepts as tools for analysis, including textural typography and transformation, perception of time and psychological engagement of an audience, and respiration as a metaphor for musical momentum. The second and third chapters apply these tools to Gerard Grisey's "Periodes" and "Partiels," and Brian Ferneyhough's "Lemma-Icon-Epigram." The fourth explores specific methodologies used in composing my dissertation piece, "Phase," including the application of number systems ranging from formal to local levels.

Customers' Attitudes toward Mobile Banking Applications in Saudi Arabia

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 statistically significant relationship between all of demographic differences: gender, education level, monthly income, and profession and mobile banking services among adopters and non-adopters. Seven attributes relating to the adoption of mobile banking applications were evaluated in this study to assess which variables affected Saudi banks customers in their adoption of mobile banking services. The findings indicated that the attributes that significantly affected the adoption of mobile banking applications among Saudis were perceived trust, perceived cost, and perceived risk. These three predictors, as a result, explained more than 60% of variance in intention to adopt mobile banking technology in Saudi Arabia. ...

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

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.

Decision-Making with Big Information: The Relationship between Decision Context, Stopping Rules, and Decision Performance

Description: Ubiquitous computing results in access to vast amounts of data, which is changing the way humans interact with each other, with computers, and with their environments. Information is literally at our fingertips with touchscreen technology, but it is not valuable until it is understood. As a result, selecting which information to use in a decision process is a challenge in the current information environment (Lu & Yuan, 2011). The purpose of this dissertation was to investigate how individual decision makers, in different decision contexts, determine when to stop collecting information given the availability of virtually unlimited information. Decision makers must make an ultimate decision, but also must make a decision that he or she has enough information to make the final decision (Browne, Pitts, & Wetherbe, 2007). In determining how much information to collect, researchers found that people engage in ‘satisficing' in order to make decisions, particularly when there is more information than it is possible to manage (Simon, 1957). A more recent elucidation of information use relies on the idea of stopping rules, identifying five common stopping rules information seekers use: mental list, representational stability, difference threshold, magnitude threshold, and single criterion (Browne et al., 2007). Prior research indicates a lack of understanding in the areas of information use (Prabha, Connaway, Olszewski, & Jenkins, 2007) and information overload (Eppler & Mengis, 2004) in Information Systems literature. Moreover, research indicates a lack of clarity in what information should be used in different decision contexts (Kowalczyk & Buxmann, 2014). The increase in the availability of information further complicates and necessitates research in this area. This dissertation seeks to fill these gaps in the literature by determining how information use changes across decision contexts and the relationships between stopping rules. Two unique methodologies were used to test the hypotheses in the conceptual ...
