Civility Matters
While the proliferation of literature on the subject of growing incivility in society demonstrates the increasing importance given to civility by corporate America, there has been little academic investigation of the concept. The limited number of academic studies on civility reveals immense negative consequences for uncivil behavior. One question for marketers of businesses is whether lack of civility among front-end personnel can negatively influence sales. This dissertation is an attempt to fill this research gap by exploring responses to uncivil behavior under the theoretical framework of attribution theory. Using the CDSII scale based on attribution theory, experimental research design was used with current civil and uncivil behavior by the store employees and past experiences (positive, negative, and no-experience) with the store as stimulus. The consumers' perception of civility, attributions and behavioral intentions were measured and used as dependent variables. The results of the experiment showed that when a customer discerns employee behavior to be uncivil, the customer's perception of the level of the ability of the employee to control his own behavior decreases. The results of the study enhance the knowledge of two important consumer behaviors, namely complaining and switching behaviors by empirically studying their antecedents in a particular market interaction context. The results imply that it is important to eliminate or minimize any experience that the customer may construe as negative at a store. If practitioners can work towards eliminating or decreasing certain attributions of consumers, they can reduce the switching behaviors and thus impact customer retention rates and future sales. Though this study contributes to marketing theory and provides vital insights to practitioners, this study is but a starting point for further examination of the role of civility in consumer behavior and decision making.
“Civilizations without Boats”: Stories
This collection consists of a critical preface and nine short stories. Extrapolating from the work and legacy of Michel Foucault, the preface theorizes a genre of “heterotopian fiction” as constitutive of a fundamentally ethical approach to narrative creativity, distinguishing its functional and methodological characteristics from works that privilege aesthetic, thematic, or technical artistry. The stories explore spaces of madness, alterity, incomprehensibility, and liminal experience. Collection includes the stories “Mexico,” “Civilizations without Boats,” The Widow’s Mother,” “Guys Like Us,” “Everything You’d Hoped It Would Be,” “A Concerned Friend,” “Crisis Hotline,” “Coast to Coast,” and “The Ghosts of Rich Men.”
Classless: on Being Middle Class in America
Classless: On Being Middle Class in America is a documentary film that explores what it means to be middle class in America. The film combines personal narrative, folksy reporting, and comedy as the film's director— Joe Brown, tries to reconcile his own status anxiety with everyday understandings of social class. Classless takes the form of a journey; the film travels through the American South, Northeast, and the Mountain West while trying to get at the heart of our middle class American Dream. Classless forwards three main arguments: (1) the American middle class is not as all-encompassing as seems; (2) Americans are more concerned about inequality than both politicians and the media suggest; and (3) many Americans are not actually middle class, economically speaking.
Claude Bolling’s Toot Suite for Trumpet and Jazz Piano: a Performance Guide
Claude Bolling’s Toot Suite for Trumpet and Jazz Piano that was premiered by French virtuoso trumpeter Maurice Andre in 1980 is an important work in the trumpet repertoire. At present, there is limited research regarding Toot Suite. Almost all of the six movements within Toot Suite are performed on a different instrument: C trumpet for Allegre, Eb trumpet for Mystique, Bb cornet for Rag-Polka, Bb piccolo trumpet for Marche, Bb flugelhorn for Vesperale and Bb piccolo for Spirituelle. Chapter 1 examines the life and musical background of the composer. It also exposes the history surrounding the origin of Toot Suite. Chapter 2 discusses the musical influences of the composer that are found in Toot Suite. Chapter 3 provides an analysis of existing studio recordings. Chapter 4 offers specific suggestions regarding preparation and performance of Toot Suite. Chapters 5 and 6 conclude the guide with interviews with the composer and prominent trumpet performers and pedagogues that have recorded and/or have performed Toot Suite live.
Clustering Algorithms for Time Series Gene Expression in Microarray Data
Clustering techniques are important for gene expression data analysis. However, efficient computational algorithms for clustering time-series data are still lacking. This work documents two improvements on an existing profile-based greedy algorithm for short time-series data; the first one is implementation of a scaling method on the pre-processing of the raw data to handle some extreme cases; the second improvement is modifying the strategy to generate better clusters. Simulation data and real microarray data were used to evaluate these improvements; this approach could efficiently generate more accurate clusters. A new feature-based algorithm was also developed in which steady state value; overshoot, rise time, settling time and peak time are generated by the 2nd order control system for the clustering purpose. This feature-based approach is much faster and more accurate than the existing profile-based algorithm for long time-series data.
Coaches’ Influence on Male Adolescents’ Achievement Motivation, Psychological Factors, and Sport Participation
The motivational climate, as created by coaches, and athletes’ goal orientations are key constructs in understanding children’s experiences with sport. In this study, the relationship between the perceived motivational climates, male adolescents’ goal orientation, and their experiences of self-esteem, sport competence, enjoyment, and ultimately, intention to continue participating in sport was examined. Participants were 405 male adolescents (Sample A: n = 200; Sample B: n = 205) aged 13-15 years old. Structural equation modeling indicated an overall good fit to the structural model for both data sets. A task goal orientation was predicted by higher levels of coach-created task climate. Participants with higher task goal orientation had greater sport competence, self-esteem, and more enjoyment in sport; enjoyment was the only significant predictor of their intention to continue playing the sport they believe is most important over the next three years.
Cold-Formed Steel Bolted Connections Using Oversized and Slotted Holes without Washers
In cold-formed steel (CFS) construction, bolted connections without washers for either oversized or slotted holes may significantly expedite the installation process and lower the cost. However, the North American Specification (AISI S100, 2007) for the Design of Cold-Formed Steel Structural Members requires washers to be installed in bolted connections with oversized or slotted holes. A research project (Phase 1) sponsored by American Iron and Steel Institute (AISI) was recently completed at the University of North Texas (UNT) that investigated the performance and strength of bolted CFS connections with oversized and slotted holes without using washers. The research presented in this thesis is the Phase 2 project in which the bolted CFS connections were studied in a broader respect in terms of the failure mechanism, the material thickness, and the hole configurations. Single shear and double shear connections without washers using oversized holes, oversized combined with standard or slotted holes were experimentally examined. Combined with Phase 1 results, the Phase 2 gives a comprehensive evaluation of the behavior and strength of bolted CFS connections with oversized and slotted holes without using washers. Revisions to the existing AISI North American Specification requirements for bolted connections are proposed to account for the reduction in the connection strength caused by the oversized and slotted hole configurations without washers. Specific LRFD and LSD resistance factors and ASD safety factors for different hole configurations in terms of the new proposed methods were presented.
Cold-formed Steel Framed Shear Wall Sheathed with Corrugated Sheet Steel
Incombustibility is one important advantage of the sheet steel sheathed shear wall over wood panel sheathed shear wall. Compared to shear wall sheathed with plywood and OSB panel, shear wall sheathed with flat sheet steel behaved lower shear strength. Although shear wall sheathed with corrugated sheet steel exhibited high nominal strength and high stiffness, the shear wall usually behaved lower ductility resulting from brittle failure at the connection between the sheathing to frames. This research is aimed at developing modifications on the corrugated sheathing to improve the ductility of the shear wall as well as derive practical response modification factor by establishing correct relationship between ductility factor ? and response modification factor R. Totally 21 monotonic and cyclic full-scale shear wall tests were conducted during the winter break in 2012 by the author in NUCONSTEEL Materials Testing Laboratory in the University of North Texas. The research investigated nineteen 8 ft. × 4 ft. shear walls with 68 mil frames and 27 mil corrugation sheet steel in 11 configurations and two more shear walls sheathed with 6/17-in.OSB and 15/32-in. plywood respectively for comparison. The shear walls, which were in some special cutting arrangement patterns, performed better under lateral load conditions according to the behavior of ductility and shear strength and could be used as lateral system in construction.
A Collaborative Affair: The Building of Museum and School Partnerships
This study examined two art museum and school partnerships in order to learn how partnerships enable an integration of goals, participants' beliefs and values, and learning objectives. This study examined the partnerships through a social constructivist lens and used narrative analysis as way to interpret participants' stories about collaboration. The research found three major themes among participants' stories. Participants: a) valued good communication to establish relationships between partners, b) believed partnership offered students experiences that educated the whole person, and c) felt that students making meaning by interacting in the museum environment was an indicator of success. The study closes with discussion of the researchers' own constructions as they developed throughout the study.
A Collective Case Study of Veterans Inside an Arts and Crafts Room and Their Perceptions Regarding Empowerment
This dissertation is "A Collective Case Study of Veterans Inside an Arts and Crafts Room and Their Perceptions Regarding Empowerment." This research examined to what degree art making, and in what ways a community of learning contributed to veterans' self-worth and empowerment through their creative activities and interactions inside an arts and crafts room at the VA hospital in Dallas, Texas. Furthermore, an essential reason for this study is to examine veterans in the arts and crafts environment to explore whether their experiences were important, meaningful, and empowering, and especially important in this regard are the interactions among veterans. Empowerment in this context is defined as gaining self-esteem and motivation within oneself. This includes becoming more confident and positive, as well as gaining the ability to learn about one's own identity. It also described how the interactions between the participants are shaped by the social contexts within which they come together. Using post-modern feminist theory, narrative inquiry and care theory, this dissertation describes the ways that the processes and products of creative activity bring empowerment through dialogue and personal stories while using the component of caring during teaching and learning.
The Collective Pedagogy Utilized By the Trombone Instructors at the Rotterdam Conservatory of the Netherlands
The Collective Pedagogy Utilized by the Trombone Instructors at the Rotterdam Conservatory of the Netherlands offers a comprehensive study of the collaboration between the various instructors of the trombone studio within the Rotterdam Conservatory and their pedagogical approach to curriculum, lesson structure, grading process, student body, and social environment. the Rotterdam Conservatory has produced some of the finest trombonists in the global music community. Alumni from the conservatory consistently win positions in professional ensembles, succeed in national and international competitions, and are often featured artists at international music festivals. the success of their alumni warrants closer scrutiny of the pedagogical approach utilized by the faculty of the conservatory.
College Student Resilience: Selected Effects of Service-Learning
Resilience implies the concept of buoyancy. Specifically, it denotes an individual's capacity to persevere and even do well in the face of adversity. Service-learning is pedagogy often used to enable students to apply classroom learning in a real world context. The goal of this study was to examine the effects of service-learning upon college student resilience. The study utilized a convenience sample of undergraduate students (N = 172) across three disciplines including counseling, social work and kinesiology. In a pre-post test design, the CD-RISC was employed to measure resilience of the experimental and control groups. Factor analysis of the CD-RISC was also conducted in order to explore interrelationship of the variables among the data. One undergraduate sample (N = 210) was used to conduct the EFA before determining a best fit factor structure for this study's population. A repeated measures analysis of variance was employed to detect any differences between pre-post test groups. No statistical significance was found across pre and post-test among the two groups (p=.49, η2=.00). However significant results were found between the experimental and control groups (p=.00, η2 =.09). Examination of mean score differences among demographic variable yielded interesting findings across the three disciplines as well as between age and gender of the participants. Findings indicated students given freedom of choice within service-learning logistics scored greatest gains in resilience.
College Success for all Students: An Investigation of Early Warning Indicators of College Readiness
The purpose of this quantitative study was to determine early warning indicators of college readiness among early college high school students at selected Texas institutions of higher education. Participants in this study included 134 of the class of 2010 from two early college high schools. The graduates were 86% Hispanic, 8% African American, 3% White, 2% Asian, 1% American Indian and 72% economically disadvantaged. A causal-comparative research design using multiple regression analysis of the data collected revealed that each one unit increase in world history was associated with a .470 (p < .05) increase in college GPA, while each one unit increase in Algebra I was associated with a .202 (p < .05) increase. Therefore, student grades in high school Algebra I and world history were the strongest statistically significant indicators that a student will maintain a 2.5 college GPA during the first year of college. According to the early warning indicators, students who maintain a grade of A or B in Algebra I are 10 times more likely to be college ready while having a 78% chance of maintaining a 2.5 or better in college courses. Further, the findings from this study found no significant relationship between TAKS assessment, socioeconomic status, gender or ethnicity and a student's ability to maintain a 2.5 or higher college GPA. Based on the findings from this study, the author recommends an examination of the high school curriculum with the goal of ensuring that students gain competency in courses that indicate college readiness.
Combat Near-Death Experiences: An Exploratory, Mixed-Methods Study
This mixed-methods study’s purpose was a systematic comparison of contents and aftereffects of near-death experiences (NDEs) occurring in a variety of circumstances with those occurring in combat. They completed an online survey: a demographic questionnaire, the Near-Death Experience Scale, the Life Changes Inventory-Revised (LCI-R), and four narrative response items. Survey completers were 68 participants: 20 combat near-death experiencers (cNDErs) and 48 non-NDErs (nNDErs). The 29% of participants who met NDE Scale criterion for an NDE was comparable to NDE incidence findings from previous retrospective studies. For statistical analyses, significance was set at p < .05, and effect size (Cohen’s d) was calculated. Mean total NDE Scale scores were significantly lower for cNDErs than variety-of-circumstance NDErs from one of two comparable studies (t = 5.083, p < .0001, d = -1.26), possibly suggesting cNDEs may have “less depth” than other-variety NDEs. Regarding cNDE aftereffects, absence of previous LCI-R data made comparison impossible. Cronbach’s alpha analysis yielded acceptable reliability on the total scale and seven of nine subscales, a finding that matched Schneeberger’s (2010); however, factor analytic results did not support the hypothesized subscale structure of the LCI-R. Although cNDErs did not score significantly higher than nNDErs on the total scale or subscales after Bonferroni correction, results indicated a possible trend toward greater absolute changes (p = 0.02, d = 0.74) and spirituality (p = 0.02, d = 0.67) with the latter finding substantiated by narrative responses. Informal analysis of narrative responses yielded several themes.
Combining of Korean Traditional Performance and Recent German Techniques in Isang Yun's Kontraste: Zwei Stücke für Violine Solo (1987)
Isang Yun (1917-1995) embraced a masterful combination of two elements derived from his life: his Korean cultural upbringing and Western musical traditions. This dissertation explores Yun's distinctive style through an analysis of his Kontraste: Zwei Stücke für Violine Solo. Following the introduction (Chapter 1), Chapter 2 contains a brief biography of Isang Yun, and explores the compositions of his Korean period (1917-1955) and his European period (1956-1995). It also discusses how Yun's musical styles changed during these two periods as a result of important life events and due to cultural and political influences. Chapter 3 examines Korean instruments such as Kayakem, Hae-Kem, and Pak; discusses Nonghyun (traditional string techniques of ornamentation in Korean music); and introduces Korean performance techniques. This chapter also provides explanations of these concepts, illustrated through various examples. A subsequent discussion illuminates Yin-Yang theory and Jeong-Jung-Dong, both elements of Taoist philosophy that influenced Yun's compositional style. This is followed by explanations of Hauptton and Umspielung, two compositional techniques that Yun developed and employed in Kontraste. Yun created the idea of Hauptton to reflect the Korean traditional concept of a single note. He used the term Umspielung ("playing around" in German) to describe his interpretation of the four traditional techniques of Nonghyun within a Western notational framework. In Chapter 5, analysis of Kontraste reveals how the piece's contrasting elements represent the concepts of Yin-Yang and Jeong-Jung-Dong, and shows how the violin imitates the sounds of Korean traditional instruments and instrumental technique. Yun's adaption of Korean traditional performance techniques to the violin in Kontraste is aimed at combining East and West and producing a new aesthetic.
Communication System over Gnu Radio and OSSIE
GNU Radio and OSSIE (Open-Source SCA (Software communication architecture) Implementation-Embedded) are two open source software toolkits for SDR (Software Defined Radio) developments, both of them can be supported by USRP (Universal Software Radio Peripheral). In order to compare the performance of these two toolkits, an FM receiver over GNU Radio and OSSIE are tested in my thesis, test results are showed in Chapter 4 and Chapter 5. Results showed that the FM receiver over GNU Radio has better performance, due to the OSSIE is lack of synchronization between USRP interface and the modulation /demodulation components. Based on this, the SISO (Single Input Single Output) communication system over GNU Radio is designed to transmit and receive sound or image files between two USRP equipped with RFX2400 transceiver at 2.45G frequency. Now, GNU Radio and OSSIE are widely used for academic research, but the future work based on GNU Radio and OSSIE can be designed to support MIMO, sensor network, and real time users etc.
Community Resilience in Thailand: a Case Study of Flood Response in Nakhonsawan City Municipality
Natural disasters such as flooding often affect vast areas and create infinite demands that need to be addressed in the same time. The wide scopes and severe impacts of such catastrophes often exceed, if not overwhelm, capacity of the national government to handle. In such a situation, communities such as cities and neighborhoods need to rely on their own capacity (resources, strategies, and expertise) to respond to disaster impacts at least until external assistance can be reached. Thus, studying how communities can be resilient to the impacts of natural disasters is important because this would enhance their ability to respond to the next disaster better. Within the context of great flooding in Thailand in 2011, this dissertation investigated the factors that generated or enhanced resilience of flood stricken-communities in Thailand. Nakhonswan City Municipality was selected as the research site. Qualitative research methods were employed in this study. Data were collected using in-depth interview and focus group. Thirty-six participants (28 for in-depth interview and 8 for focus group interview) from various organizations were recruited using snowball and purposive sampling strategies. Interview data from the field research were transcribed, translated from Thai language to English, and then analyzed using open coding and focused coding strategies. Analyses of in-depth interview data revealed eight conceptual themes representing factors that constituted resilience of Nakhonsawan City Municipality, as the leading organization responded to the flood. These factors are: availability of resources for resilience; managerial adaptability; crisis leadership; quality workforce; knowledge sharing and learning; organizational preparedness; organizational integration; and sectoral integration. In addition, findings from the focus group interview with members of three strong neighborhoods found eight factors that helped these neighborhoods respond effectively to the flood crisis. They included: self-reliance; cooperation; local wisdom; preparedness; internal support; external support; crisis adaptability; and pre-disaster social cohesion. This dissertation ended with the discussion of implications, limitations and suggestions for future research.
Comparative Analysis Of 105 Higher Education Doctoral Programs In The United States
The mission types of 105 current doctoral programs in higher education and the extent to which their missions have changed since a similar study was conducted by Dressel and Mayhew in 1974 was studied. The curricula offerings of these programs by degree type (e.g., Ed.D. & Ph.D.) were compared with Fife’s 1991 findings. Finally, the study examined the various modes of instruction (e.g., classroom, online, cohort, blended) these programs utilize. The population was the 131 U.S. higher education doctoral program coordinators or directors who were identified using the ASHE Higher Education Program Directory. A total of 46 hosted Ed.D. programs and 59 hosted Ph.D. programs for a combined total of 105 doctoral programs. An electronic survey, developed by utilizing an expert panel and the cognitive interviewing technique, was sent to each participant. A total of 46 hosted Ed.D. programs and 59 hosted Ph.D. programs for a combined total of 105 doctoral programs. A total of 77 institutions (59%) returned usable questionnaires, and six other universities (5%) indicated their doctoral higher education programs no longer existed. Twenty-three of the responding institutions identified with a research-focused mission; 25 institutions identified with a practitioner-based mission; and 28 institutions identified with both types of missions. Pearson r correlation analysis revealed no statistically significant relationship between degree type and course offerings (r = .123, p = .05). However, ? 2 revealed that, compared to Ed.D. programs, Ph.D. programs enrolled significantly more full-time students (? 2 (3) = 14.504, p < .05). Through further analysis, a core of nine courses emerged for more than 75% of all higher education doctoral programs. Those courses are general administration of higher education, finance of higher education, legal studies, history of higher education, philosophy and theoretical foundations of higher education, teaching/learning in higher education, student affairs administration, college student research, and a dissertation seminar. Nearly 80% of all doctoral programs utilize some form of alternate delivery method (e.g., online, cohort, blended) in addition to traditional classroom instruction. Furthermore, Ph.D. programs employ larger full-time faculties, conduct more research, obtain more external funding, and publish more scholarship than Ed.D. programs.
A Comparative Analysis of the 1915 and 1919 Versions of Symphony No. 5 in E-flat Major, op. 82 by Jean Sibelius
The initial composition of the Fifth Symphony in E-flat Major, Op. 82 was undertaken as a commission to celebrate the composer's fiftieth birthday. Unhappy with the initial efforts, two revisions were then performed; the first was in 1916 and the final revision in 1919. Despite the larger form of the work seeming to have been changed between the 1915 and 1919 versions, the smaller gestures of thematic expression in both versions remained similar. On the surface, it had appeared that the composer had eliminated a movement, changing the 1919 version into a three movement form. This view was not challenged by the composer at the time, and since the earlier versions had either been withdrawn or destroyed, there was no way to compare the original efforts to the final product until recently. In comparing the 1919 version to the original, a definite strong parallel can be seen between the two - despite the changes to form, rearrangement of melodic material, and the seemingly different number of movements. However, the parallel is enough that the 1915 version can be a guide to classifying the 1919 version, an act that has eluded many scholars since the 1920s. Most importantly, comparing the two versions shows that the 1919 version is not a three movement form at all; it is a four movement form that is obscured by the connection of the first and second movements by a thematic bridge that contains elements from both movements, but is not placed within either structure.
A Comparative Analysis of Web-based Machine Translation Quality: English to French and French to English
This study offers a partial reduplication of a 2006 study by Williams, which focused primarily on the analysis of the quality of translation produced by online software, namely Yahoo!® Babelfish,, and Google Translate. Since the data for the study by Williams were collected in 2004 and the data for present study in 2012, this gives a lapse of eight years for a diachronic analysis of the differences in quality of the translations provided by these online services. At the time of the 2006 study by Williams, all three services used a rule-based translation system, but, in October 2007, however, Google Translate switched to a system that is entirely statistical in nature. Thus, the present study is also able to examine the differences in quality between contemporary statistical and rule-based approaches to machine translation.
Comparative Phyto-uptake Across Distribution Coefficients of Pharmaceutical Compounds and Aquatic Macrophytes: Carbamazepine and Amiodarone Uptake in Lemna Spp
Few studies have been conducted on the effectiveness of phytoremediation of pharmaceutical compounds, although the persistent and non-acutely toxic nature of many of these compounds in today's water bodies may yield an ideal application for this practice. To quantify the potential effectiveness of plant uptake, kinetic and proportional bioconcentration factors (BCFk, and BCFp, respectively) in nanograms (ng) carbamazepine and amiodarone per gram (g) wet weight plant tissue for Lemna spp. were determined utilizing a 14-day continuous flow-through study. Samples were analyzed using isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) running in positive ion mode. Kinetic BCF was estimated at 0.538, while proportional BCF was estimated at 0.485. Kinetic BCF for the amiodarone study was estimated at 23.033, whereas proportional BCF was estimated at 41.340. Possible contamination of the C18 column and peristaltic pump failure may have impacted uptake results. In light of variability and current lack of research in the field, this work should be considered exploratory rather than conclusive.
A Comparative Study of Non Linear Conjugate Gradient Methods
We study the development of nonlinear conjugate gradient methods, Fletcher Reeves (FR) and Polak Ribiere (PR). FR extends the linear conjugate gradient method to nonlinear functions by incorporating two changes, for the step length αk a line search is performed and replacing the residual, rk (rk=b-Axk) by the gradient of the nonlinear objective function. The PR method is equivalent to FR method for exact line searches and when the underlying quadratic function is strongly convex. The PR method is basically a variant of FR and primarily differs from it in the choice of the parameter βk. On applying the nonlinear Rosenbrock function to the MATLAB code for the FR and the PR algorithms we observe that the performance of PR method (k=29) is far better than the FR method (k=42). But, we observe that when the MATLAB codes are applied to general nonlinear functions, specifically functions whose minimum is a large negative number not close to zero and the iterates too are large values far off from zero the PR algorithm does not perform well. This problem with the PR method persists even if we run the PR algorithm for more iterations or with an initial guess closer to the actual minimum. To improve the PR algorithm we suggest finding a better weighing parameter βk, using better line search method and/or using specific line search for certain functions and identifying specific restart criteria based on the function to be optimized.
A Comparative Study of the Effects of State Grant Reductions on Local Expenditures: Empirical Studies in Massachusetts and Colorado Municipalities
State grants are perceived to mitigate the fiscal disparities among local governments in providing services. However, cutbacks in state grants as a result of changes in state grant policy in different states affect local expenditures dedicated to maintaining service provisions to citizens. This dissertation constructs a theoretical model to explain the extent to which and the ways in which types of state grants, revenue diversity, and form of local government impact local spending and the provision of public programs when local governments experience cuts in state grants. The dissertation also argues that when facing state grant cuts, local governments with a council-manager form of government and with higher revenue diversity will experience reduced change in local expenditures and that decreases in state categorical grants will lead to more cuts in distributive program expenditures. Given the diversity of state and local arrangements, this dissertation conducts a comparative and panel data study to test the hypotheses in 351 and 271 municipalities in Massachusetts and Colorado, respectively, in 2000 through 2008. The empirical results indicate that the form of government and the degree of revenue diversification have a greater impact on the local spending behaviors in Colorado than in Massachusetts. Meanwhile, decreases in state categorical grants lead to more cuts in distributive program expenditures in both Massachusetts and Colorado. This dissertation concludes that the theoretical model explains the effects of state grant reductions on local spending better in Colorado than it does in Massachusetts.
A Comparative Study of Two Single-Subject Keyboard Ricercare by Johann Jacob Froberger: Projections of Sixteenth-Century Practice Combined with Features that Forecast Baroque Practice
This study is focused on an analysis of two single-subject ricercare in the keyboard music of Johann Jacob Froberger and examines possible pathways to the development of the Baroque fugue. This dissertation is divided into three parts. Chapter I contains the purpose, significance of this study and composer, as well as characteristics of the seventeenth-century single-subject ricercar. Chapter II details and examines Froberger's two ricercare. Finally, a conclusion of this study is presented in Chapter III. Two appendixes are included in this dissertation: a list of the single-subject ricercare of Andrea Gabrieli, Giovanni Gabrieli, and Johann Jacob Froberger; and an analysis of the two single-subject ricercare, FbWV 407 and FbWV 409, by Johann Jacob Froberger.
Comparing Indices of Happiness during Teaching Interactions
The measurement of happiness has received increasing attention in behavior analytic literature. Happiness in individuals with developmental disabilities has been assessed by 1) counting a specific behavior, or 2) sampling constellations of behaviors. The purpose of this study was to examine the two approaches while observing nine child and teacher dyads at an autism treatment center. Results showed that, overall, a constellation of behaviors can yield similar patterns when compared to a specific behavior count. However, the affect of one person did not predict the affect of the other and similar instructional conditions did not predict affect either. The implications of these results and future directions are discussed.
Comparing Latent Dirichlet Allocation and Latent Semantic Analysis as Classifiers
In the Information Age, a proliferation of unstructured text electronic documents exists. Processing these documents by humans is a daunting task as humans have limited cognitive abilities for processing large volumes of documents that can often be extremely lengthy. To address this problem, text data computer algorithms are being developed. Latent Semantic Analysis (LSA) and Latent Dirichlet Allocation (LDA) are two text data computer algorithms that have received much attention individually in the text data literature for topic extraction studies but not for document classification nor for comparison studies. Since classification is considered an important human function and has been studied in the areas of cognitive science and information science, in this dissertation a research study was performed to compare LDA, LSA and humans as document classifiers. The research questions posed in this study are: R1: How accurate is LDA and LSA in classifying documents in a corpus of textual data over a known set of topics? R2: How accurate are humans in performing the same classification task? R3: How does LDA classification performance compare to LSA classification performance? To address these questions, a classification study involving human subjects was designed where humans were asked to generate and classify documents (customer comments) at two levels of abstraction for a quality assurance setting. Then two computer algorithms, LSA and LDA, were used to perform classification on these documents. The results indicate that humans outperformed all computer algorithms and had an accuracy rate of 94% at the higher level of abstraction and 76% at the lower level of abstraction. At the high level of abstraction, the accuracy rates were 84% for both LSA and LDA and at the lower level, the accuracy rate were 67% for LSA and 64% for LDA. The findings of this research have many strong implications for the improvement of information systems that process unstructured text. Document classifiers have many potential applications in many fields (e.g., fraud detection, information retrieval, national security, and customer management). Development and refinement of algorithms that classify text is a fruitful area of ongoing research and this dissertation contributes to this area.
Comparing the 2010 and 2011 Appic Match: Applicant Characteristics and Unmatched Applicant Distress
The internship is one of the most important components of doctoral training in professional psychology. Given the serious problem of the internship imbalance, applicant and program characteristics that constitute a good “fit” with internship training programs have become of greater interest as securing an internship becomes a more competitive process. This study surveyed internship applicants from programs part of the Council of University Directors of Clinical Psychology (CUDCP), before and after the 2010 and 2011 match days. Number of interview offers was found to be the factor most consistently associated with successfully matching, and several other applicant characteristics salient to matching and obtaining interview offers were identified, including applicant personality. Additionally, personal accounts, but not empirical evidence, of going unmatched have attested to the psychological distress associated with this event. in the current study, while going unmatched was not found to be equitable to a traumatic stressor, evidence was found to support significant decrease in subjective well-being with respect to immediate distress. Findings are discussed in terms of the predictability of and implications for the match process and internship imbalance, and recommendations are made for future research directions.
Comparing the Effects of Home Versus Clinic-Based Parent Training for Children with Autism
Research with parents on managing child problem behavior typically measures either child or parent behavior. This study was designed to evaluate the effectiveness of training parents to implement a function-based behavior intervention plan (BIP) in a non-trained natural environment utilizing a Multiple Probe Design across Participants. Participants included four parent-child dyads. Measurement variables included parents' use of effective and ineffective strategies and child problem behavior. Intervention involved training parents to understand and implement the BIP using effective strategies, modeling the effective procedures, and providing feedback following parent implementation of procedures. Results showed that the intervention was very effective in promoting skill generalization of parents and decreasing child problem behavior. The findings have implications for research and clinical practice.
Comparing the Readability of Text Displays on Paper, E-Book Readers, and Small Screen Devices
Science fiction has long promised the digitalization of books. Characters in films and television routinely check their palm-sized (or smaller) electronic displays for fast-scrolling information. However, this very technology, increasingly prevalent in today's world, has not been embraced universally. While the convenience of pocket-sized information pieces has the techno-savvy entranced, the general public still greets the advent of the e-book with a curious reluctance. This lack of enthusiasm seems strange in the face of the many advantages offered by the new medium - vastly superior storage capacity, searchability, portability, lower cost, and instantaneous access. This dissertation addresses the need for research examining the reading comprehension and the role emotional response plays in the perceived performance on e-document formats as compared to traditional paper format. This study compares the relative reading comprehension on three formats (Kindle, iTouch, and paper) and examines the relationship of subject's emotional response and relative technology exposure as factors that affect how the subject perceives they have performed on those formats. This study demonstrates that, for basic reading comprehension, the medium does not matter. Furthermore, it shows that, the more uncomfortable a person is with technology and expertise in the requested task (in this case, reading), the more they cling to the belief that they will do better on traditional (paper) media - regardless of how well they actually do.
Comparison of Aspartate Transcarbamoylase Activity Between Pseudomonas Aeruginosa Which Has One Chromosome and Burkholderia Cepacia Which Has Three Chromosomes
The pyrimidine biosynthetic pathway is essential and similar in all bacteria. The pathway from Pseudomonas is regulated by nucleotides which bind to the upstream region of the pyrBC’ gene complex. Work in our lab mapped the genes and showed that the pyrB and pyrC’ were part of an overlap complex. The Pseudomonas aeruginosa has one circular chromosome. A former Pseudomonas now called Burkholderia cepacia is similar to P. aeruginosa except that it contains three circular chromosomes (CI, CII, CIII) and one large plasmid. The primary chromosome named CI contains the pyrBC’. To our knowledge there has been no report of the activity of ATCase in Pseudomonas and contrasted with that of Burkholderia. Here, we compare the activity of ATCase in P. aeruginosa and B .cepacia. Cells of both organisms were grown in Pseudomonas minimal medium and in Enriched medium. The ATCase was extracted and partially purified from each sample. It is hypothesized that the B. cepacia has greater activity for ATCase than do the Pseudomonas.
Comparison of Heteranthera Dubia (Jacq.) MacM.-associated Macroinvertebrates Between Georgraphical Regions in the United States
Macroinvertebrates associated with the aquatic plant, water stargrass (Heteranthera dubia), were sampled from 12 waterbodies in four regions of the United States from June to August 2005. Taxa richness, evenness, and diversity were lowest in the Lower Midwest (LMW) region, and higher in Northern sites, especially the Upper Midwest (UMW), and Northeast (NE). While relative abundance varied from site to site and region to region, utilization of the plant by functional groups remained fairly constant. Collector-gatherers consistently comprised the largest portion of invertebrates sampled. The shredder/ herbivore functional group comprised an average of 17 % of total groups. Through an exhaustive literature review, it was found that shredder/ herbivores of water stargrass have not been reported in the literature. Because of this, the herbivore group was analyzed separately and consisted of 2,383 specimens representing 23 species. The most common groups were Rhopalosiphum sp., Nectopsyche spp. and chironomids. No differences were found in herbivore diversity or evenness between sampling regions, but species richness was significantly different.
A Comparison of Mercury Localization, Speciation, and Histology in Multiple Fish Species From Caddo Lake, a Fresh Water Wetland
This work explores the metabolism of mercury in liver and spleen tissue of fish from a methylmercury contaminated wetland. Wild-caught bass, catfish, bowfin and gar were collected. Macrophage centers, which are both reactive and primary germinal centers in various fish tissues, were hypothesized to be the cause of demethylation of methylmercury in fish tissue. Macrophage centers are differentially expressed in fish tissue based on phylogenetic lineage, and are found primarily in the livers of preteleostean fish and in the spleen of teleostean fish. Histology of liver and spleen was examined in both control and wild-caught fish for pathology, size and number of macrophage centers, and for localization of mercury. Total mercury was estimated in the muscle tissue of all fish by direct mercury analysis. Selenium and mercury concentrations were examined in the livers of wild-caught fish by liquid introduction inductively coupled plasma mass spectrometry (ICP-MS). Total mercury was localized in histologic sections by laser ablation ICP-MS (LA-ICP-MS). Mercury speciation was determined for inorganic and methylmercury in liver and spleen of fish by bas chromatography-cold vapor atomic fluorescence spectroscopy (GC-CVAFS). Macrophage center tissue distribution was found to be consistent with the literature, with a predominance of centers in preteleostean liver and in spleens of teleostean fish. Little evidence histopathology was found in the livers or spleens of fish examined, but differences in morphology of macrophage centers and liver tissue across species are noted. the sole sign of liver pathology noted was increased hepatic hemosiderosis in fish with high proportions of liver inorganic mercury. Inorganic mercury was found to predominate in the livers of all fish but bass. Organic mercury was found to predominate in the spleens of all fish. Mercury was found to accumulate in macrophage centers, but concentrations of mercury in this compartment were found to vary less in relation to total mercury than hepatocyte mercury. No association was found between selenium content and inorganic mercury proportions. Overall, findings from this study to not support a primary role for macrophage centers in the demethylation of methylmercury in fish tissues.
A Comparison of Picture to Word Training and Word to Word Training on Native English Speaking College Students’ Acquisition of Italian Vocabulary
The current study assessed the effects of two teaching stimulus presentations, i.e. picture to word and word to word, used to teach second language vocabulary to college students. It also evaluated the emergence of untaught relations when picture to word and word to word were used separately as a teaching strategy. The findings showed picture to word training resulted in more untaught relations. Several aspects such time allotted for online quizzes, experimental and teaching arrangements and vocabulary complexity were suggested for future research.
A Comparison of Principals’ Perceptions of Preparedness Based on Leadership Development Opportunities
This research study identified the frequency in which six public school districts in Texas provided principals with effective development opportunities prior to the principalship excluding university or certification programs. A purposive sample of over 200 principals from six school districts in the Dallas/Fort Worth area were asked to participate in the study yielding a response rate of 41%. Respondents identified through a questionnaire their leadership development opportunities and perceptions of preparedness on nine standards common to the profession. Principals were nominally grouped for comparison. The perceptions of preparedness for principals who received effective leadership development opportunities were compared to those who did not receive these same opportunities using an independent samples t-test to determine statistical significance (p < .05). Peer coaching yielded the most statistically significant results in three standards. This finding indicates principals who receive peer coaching prior to the principalship compared to those who did not perceive themselves as more prepared in the areas of community collaboration, political, social, economic, legal, and cultural context, and curriculum, instruction and assessment. Effect size was measured for the statistically significance standards to determine practical significance. Each of the five statistically significant standards yielded a medium effect size indicating that the leadership development methods received by participants explained approximately 30% of the difference.
A Comparison of the Pittsburgh Sleep Quality Index, a New Sleep Questionnaire, and Sleep Diaries
Self-report retrospective estimates of sleep behaviors are not as accurate as prospective estimates from sleep diaries, but are more practical for epidemiological studies. Therefore, it is important to evaluate the validity of retrospective measures and improve upon them. The current study compared sleep diaries to two self-report retrospective measures of sleep, the commonly used Pittsburgh Sleep Quality Index (PSQI) and a newly developed sleep questionnaire (SQ), which assessed weekday and weekend sleep separately. It was hypothesized that the new measure would be more accurate than the PSQI because it accounts for variability in sleep throughout the week. The relative accuracy of the PSQI and SQ in obtaining estimates of total sleep time (TST), sleep efficiency (SE), and sleep onset latency (SOL) was examined by comparing their mean differences from, and correlations with, estimates obtained by the sleep diaries. Correlations of the PSQI and SQ with the sleep diaries were moderate, with the SQ having significantly stronger correlations on the parameters of TST, SE, and sleep quality ratings. The SQ also had significantly smaller mean differences from sleep diaries on SOL and SE. The overall pattern of results indicated that the SQ performs better than the PSQI when compared to sleep diaries.
A Comparison of Three Teacher Evaluation Methods and the Impact on College Readiness
Much attention in recent years has gone to the evaluation of teacher effectiveness, and some scholars have developed conceptual models to evaluate the effectiveness. The purpose of this study was to compare three teacher evaluation models – the Texas Professional Development Appraisal System (PDAS), the teacher index model (TI), and the value-added model (VAM) – to determine teacher effectiveness using student demographic and longitudinal academic data. Predictive data from students included economic disadvantage status, ethnicity, gender, participation in special education, limited English proficiency, and performance on Texas Assessment of Knowledge and Skills (TAKS). Data serving as dependent variables were scores from Scholastic Aptitude Test (SAT®) verbal/critical reasoning and mathematics. These data came from 1,714 students who were 9.7% Hispanic, 9.2% African American, and 81.2% White. The models were tested for 64 English language arts teachers and 109 mathematics teachers, using student examination scores from the SAT® verbal/critical reasoning and mathematics. The data were aligned for specific faculty members and the students whom they taught during the year of the study. The results of the study indicated that the TI and VAM explained approximately 42% of the variance in college entrance exam scores from the SAT® verbal/critical reasoning and mathematics (R2 = 0.418) across mathematics and English language arts teachers, whereas the TI model explained approximately 40% of the variance in the SAT® scores (R2 = 0.402). The difference, however, in the R-squared values between the VAM and the TI model was not statistically significant (t (169) = 1.84, p > 0.05), suggesting that both models provided similar results. The least effective model used to predict student success on college entrance exams was the PDAS, which is a state-adopted model currently in use in over 1,000 school districts in Texas, The teacher PDAS scores explained approximately 36% of the variance in student success on the SAT® (R2 = 0.359). The study provides school leadership with information about alternative methods of evaluating teacher effectiveness without difficult formulas or high costs associated with hiring statisticians. In addition, results indicate that the models vary significantly in the extent to which they can predict which teachers are most effective in preparing students for college. This study also emphasizes the critical need to provide teacher evaluations that align with student achievement on college entrance exams.
A Comparison of Transfer of Stimulus Control Or Multiple Control on the Acquisition of Verbal Operants in Young Children with Autism: an Extension
One language intervention approach for individuals with autism involves teaching one response topography under multiple sources of control and then establishing that response under individual controlling variable. Another approach involves establishing one response topography under singular control and then using that response to establish the response topography under different controlling variables. The study sought to extend previous research by investigating the impact of each approach on the acquisition of verbal responses. Three of the eight participants acquired all target responses for at least one response topography. The results of previous research were not replicated directly and the findings were discussed in terms of preexperimental verbal repertoires and restricted interests.
A Comparison of Vocabulary Banks and Scripts on Native English-speaking Students’ Acquisition of Italian
The study applied behavior analytic principles to foreign language instruction in a college classroom. Two study methods, vocabulary banks and scripts, were compared by assessing the effects on Italian language acquisition, retention, and generalization. Results indicate that students without prior exposure to Italian engaged in more exchanges and emitted more words in script tests compared to vocabulary bank tests. Participants with at least two classes in Italian prior to the study engaged in more exchanges and emitted more words during vocabulary bank tests. Data suggest that different teaching strategies may work for different learners. More research is needed to determine efficient teaching methods and how to ascertain which approaches work best for learners with different histories.
The Compositional Transformation and Musical Rebirth of Leo Ornstein
This study focuses on the transformation of Leo Ornstein’s (1893-2002) musical language of his early years into the strikingly different approach found in his later years. Ornstein’s initial radical compositions from the mid-1910s were no doubt representative of the direction in which modern music was moving. Despite the intense fame and notoriety of his early works, Ornstein did not feel connected to the trends of modern music development, and by the end of the 1930s he withdrew from the public scene and turned to teaching. By the 1950s Ornstein had been almost forgotten, and in later life he became a very private person. He worked in almost total isolation composing a substantial amount of music well into his nineties, and died at the age of 109. The music of Ornstein’s “second life” is very different from the initial works of his early years, and most of it is unknown to the public and should be brought into scholarly light, especially since Ornstein has been considered by historians as a pivotal figure in twentieth-century music. This study examines selected music from different stages of Ornstein’s career: Wild Men’s Dance (1913), Suicide in an Airplane (1913), Arabesques (1918), A Long Remembered Sorrow (1964), Piano Sonata No. 7 (1988). A discussion of the selected compositions will provide an understanding of Ornstein’s compositional transformation, and will familiarize musicians and scholars with this widely unknown music.
A Comprehensive Modeling Framework for Airborne Mobility
Access: Use of this item is restricted to the UNT Community.
Mobility models serve as the foundation for evaluating and designing airborne networks. Due to the significant impact of mobility models on the network performance, mobility models for airborne networks (ANs) must realistically capture the attributes of ANs. In this paper, I develop a comprehensive modeling framework for ANs. The work I have done is concluded as the following three parts. First, I perform a comprehensive and comparative analysis of AN mobility models and evaluate the models based on several metrics: 1) networking performance, 2) ability to capture the mobility attributes of ANs, 3) randomness levels and 4) associated applications. Second, I develop two 3D mobility models and realistic boundary models. The mobility models follow physical laws behind aircraft maneuvering and therefore capture the characteristics of aircraft trajectories. Third, I suggest an estimation procedure to extract parameters in one of the models that I developed from real flight test data. The good match between the estimated trajectories and real flight trajectories also validate the suitability of the model. The mobility models and the estimation procedure lead to the creation of “realistic” simulation and evaluation environment for airborne networks.
Computational Investigation of Molecular Optoelectronic and Biological Systems
The scope of work in this dissertation has comprised several major investigations on applications and theoretical studies of ab initio quantum mechanics and density functional theory where those techniques were applied to the following: (i) investigation of the performance of density functionals for the computations of molecular properties of 3d transition metal containing systems; (ii) guidance for experimental groups for rational design of macrometallocyclic multinuclear complexes with superior π-acidity and π-basicity that are most suitable for p- and n-type semiconductors of metal-organic molecules and nanomaterials; (iii) investigation of the metallo-aromaticity of multi-nuclear metal complexes; (iv) investigation of the kinetics and thermodynamics of copper-mediated nitrene insertion into C-H and H-H bond; and (v) accurate computations of dissociation energies of hydrogen-bonded DNA duplex moieties utilizing the resolution of identity correlation consistent composite approach (RI-ccCA).
Computational Studies of Inorganic Systems with a Multiscale Modeling Approach: From Atomistic to Continuum Scale
Multiscale modeling is an effective tool for integrating different computational methods, creating a way of modeling diverse chemical and physical phenomena. Presented are studies on a variety of chemical problems at different computational scales and also the combination of different computational methods to study a single phenomenon. The methods used encompass density functional theory (DFT), molecular dynamics (MD) simulations and finite element analysis (FEA). The DFT studies were conducted both on the molecular level and using plane-wave methods. The particular topics studied using DFT are the rational catalyst design of complexes for C—H bond activation, oxidation of nickel surfaces and the calculation of interaction properties of carbon dioxide containing systems directed towards carbon dioxide sequestration studies. Second and third row (typically precious metals) transition metal complexes are known to possess certain electronic features that define their structure and reactivity, and which are usually not observed in their first-row (base metal) congeners. Can these electronic features be conferred onto first-row transition metals with the aid of non-innocent and/or very high-field ligands? Using DFT, the impact of these electronic features upon methane C—H bond activation was modeled using the dipyridylazaallyl (smif) supporting ligand for late, first-row transition metal (M) imide, oxo and carbene complexes (M = Fe, Co, Ni, Cu; E = O, NMe, CMe2). To promote a greater understanding of the process and nature of metal passivation, first-principles analysis of partially oxidized Ni(111) and Ni(311) surface and ultra-thin film NiO layers on Ni(111) was performed. A bimodal theoretical strategy that considers the oxidation process using either a fixed GGA functional for the description of all atoms in the system, or a perturbation approach, that perturbs the electronic structure of various Ni atoms in contact with oxygen by application of the GGA+U technique was applied. Binding energy of oxygen to the nickel surfaces, charge states of nickel and oxygen, and the preferred binding mode of oxygen to nickel were studied to gain a better understanding of the formation of oxide layers. Using density functional theory, the thermodynamic properties for developing interaction potentials for molecular dynamics simulations of carbon dioxide systems were calculated. The interactions considered are Ni + H2O, Ni + Ni, Ni + CO2, CO2 + CO2, CO2 + H2O and H2O + H2O. These systems were chosen as the possible interactions that can occur when carbon dioxide is stored in the ocean. Molecular dynamics simulations using the results from the DFT studies were also conducted. Finally, thermal conduction analysis was performed on layered functionally graded materials (FGM) subjected to thermal shock by sudden cooling of the material in order to investigate the results obtained from three different mixing laws: linear, quadratic, and half-order. The functionally graded material considered was a composite of nickel and carbon nanotubes at different compositions varying from two to five layers. The middle layers for the three to five layers are composed of graded (i.e., gradually changing) percentages of nickel and carbon nanotube. The thermal conductivity, specific heat and density for the composites were calculated depending on the percentages of materials in each layer, and assuming different rules of mixture.
Computational Study of Small Molecule Activation via Low-Coordinate Late First-Row Transition Metal Complexes
Methane and dinitrogen are abundant precursors to numerous valuable chemicals such as methanol and ammonia, respectively. However, given the robustness of these substrates, catalytically circumventing the high temperatures and pressures required for such transformations has been a challenging task for chemists. In this work, computational studies of various transition metal catalysts for methane C-H activation and N2 activation have been carried out. For methane C-H activation, catalysts of the form LnM=E are studied, where Ln is the supporting ligand (dihydrophosphinoethane or &#946;-diketiminate), E the activating ligand (O, NCH3, NCF3) at which C-H activation takes place, and M the late transition metal (Fe,Co,Ni,Cu). A hydrogen atom abstraction (HAA) / radical rebound (RR) mechanism is assumed for methane functionalization (CH4 à CH3EH). Since the best energetics are found for (&#946;-diket)Ni=O and (&#946;-diket)Cu=O catalysts, with or without CF3 substituents around the supporting ligand periphery, complete methane-to-methanol cycles were studied for such systems, for which N2O was used as oxygen atom transfer (OAT) reagent. Both monometallic and bimetallic OAT pathways are addressed. Monometallic Fe-N2 complexes of various supporting ligands (LnFe-N2) are studied at the beginning of the N2 activation chapter, where the effect of ligand on N2 activation in end-on vs. side-on N2 isomers is discussed. For (&#946;-diket)Fe-N2 complexes, the additional influence of diketiminate donor atom (N(H) vs. S) is briefly addressed. The remainder of the chapter expands upon the treatment of &#946;-diketiminate complexes. First, the activation and relative stabilities of side-bound and end-bound N2 isomers in monometallic ((&#946;-diket)M-N2) and bimetallic ((&#946;-diket)M-N2-M(&#946;-diket)) first row transition metal complexes are addressed. Second, the thermodynamics of H/H+/H- addition to (&#946;-diket)Fe-bound N2, followed by subsequent H additions up to release of ammonia, is discussed, for which two mechanisms (distal and alternating) are considered. Finally, the chapter concludes with partial distal and alternating mechanisms for H addition to N2 in bimetallic (&#946;-diket)Fe-N2-Fe(&#946;-diket) and (&#946;-diket)M-N2-M(&#946;-diket) (M = Ti,V,Fe), respectively.
The Concept of Purgatory in England
It is not the purpose of this dissertation to present a history of Purgatory; rather, it is to show through the history the influence of purgatorial doctrine on the English lay community and the need of that community for this doctrine. Having established the importance this doctrine held for so many in England, with an examination of the chantry institution in England, this study then examines how this doctrine was stripped away from the laity by political and religious reformers during the sixteenth century. Purgatorial belief was adversely affected when chantries were closed in execution of the chantry acts under Henry VIII and Edward VI. These chantries were vital to the laity and not moribund institutions. Purgatorial doctrine greatly influenced the development and concept of the medieval English community. Always seen to be tightly knit, this community had a transgenerational quality, a spiritual and congregational quality, and a quality extending beyond the grave. The Catholic Church was central to this definition of community, distributing apotropaic powers, enhancing the congregational aspects, and brokering the relationship with the dead. The elements of the Roman liturgy were essential to community cohesiveness, as were the material and ritual supports for this liturgy. The need of the community for purgatorial doctrine shaped and popularized this doctrine Next, an analysis of surviving and resurging elements of expiatory rites is explored; ritual, especially that surrounding death, as well as the relationship with the dead, were sorely missed when stripped away through political actions linked to Protestant belief. This deficiency of ritual aspects within the emerging Protestant religion became evident in further years as some of the same customs and rituals that were considered anathema by Protestants slowly crept back into the Protestant liturgy in an attempt to restore the relationship between the living and the dead. Strong evidence of this is provided through sixteenth to nineteenth century death eulogies, surviving rites of expiation, as well as lay essays and popular literature discussing the phenomenon called the Sin-Eater.
The Concept Of “Unity” In Isang Yun’s Königliches Thema Fr Violine Solo
A Korean-German composer Isang Yun.s life was evenly distributed between two different countries, and his music contains both elements of performance practices of Eastern Asian and Western music. This dissertation presents his ethnic and aesthetic musical roots by an analytic examination of his solo violin piece, K♠nigliches Thema (1976). The dissertation is divided into four chapters. The first chapter contains Isang Yuns biography and his works of the four periods. The second chapter studies his philosophy in music and compositional techniques such as twelve-tone technique, Taoism, Hauptton, Hauptklang and the Korean instrumental technique in Western instruments. The third chapter presents a detailed analysis of Knigliches Thema with his Taoist philosophy. The fourth chapter is solely dedicated to the performance perspectives of Königliches Thema in tempo, dynamic and various violin techniques.
Conductor Awareness of, Knowledge of, and Attitude Toward Sound Intensity Levels Generated During Ensemble-based Instructional Activities in College-level Schools of Music
In 2011, the National Association of Schools of Music (NASM) took an official position to recognize the importance of hearing health and injury prevention as a standard for all member-accredited institutions. This is the largest national acknowledgement promoting hearing health and safety within the music discipline and among students seeking a music degree in the United States. The purpose of the study is to describe what conductors (i.e., instructors) of college-based ensembles know about hearing health and the generation of sound intensity levels. The study aimed to describe the 1) current state of conductors’ awareness and knowledge of sound intensity levels, 2) current attitudes of conductors toward learning and sharing knowledge of sound intensity levels, and 3) current teaching practices of conductors in regard to equipment usage (e.g. sound level meter, noise dosimeter, hearing protection devices) relating to sound measurement and exposure. Findings indicate 80.2% of conductors (N = 162, 66% employed by NASM-accredited institutions) agree that sounds generated during ensemble-based instructional activities (EBIAs) in college-level schools of music are capable of harming human hearing, but 24.1% “do not know” if EBIAs they conduct ever exceed sound intensity levels capable of harming human hearing, 54.9% do not know “what services or resources” their home institutions offer/refer to students, 93% are never using a noise dosimeter, 40% have never had an audiology exam, and 70% have never used hearing protection during an EBIA. Conductors have a strong openness to change current teaching practices and inform themselves about hearing health, but few are personally informing and educating their students during the EBIA. The study serves to assist conductors and foster a new dialogue among their students, colleagues, staff, and administrators to revise current curriculum, explore sound measurement technologies, and evaluate current hearing health and safety issues inherent in the practice, performance, and teaching of sound intensity levels generated during EBIAs in college-level schools of music.
Confirming the Constructs of the Adlerian Personality Priority Assessment (Appa)
The primary purpose of this study was to confirm the four-factor structure of the 30-item Adlerian Personality Priority Assessment (APPA) using a split-sample cross-validation confirmatory factor analysis (CFA). The APPA is an assessment, grounded in Adlerian theory, used to conceptualize clients based on the four personality priorities most commonly used in the Adlerian literature: superiority, pleasing, control, and comfort. The secondary purpose of this study was to provide evidence for discriminant validity, examine predictive qualities of demographics, and explore the prevalence of the four priorities across demographics. For the cross validation CFA, I randomly divided the sample, 1210 undergraduates, at a large public research university (53% Caucasian, 13.1% Hispanic/Latino(a), 21.4% African American, 5.4% American Indian, and 5.8% biracial; mean age =19.8; 58.9% females), into two equal subsamples. I used Subsample 1 (n = 605) to conduct the initial CFA. I held out Subsample 2 (n = 605) to test any possible model changes resulting from Subsample 1 results and to provide further confirmation of the APPA's construct validity. Findings from the split-sample cross-validation CFA confirmed the four-factor structure of the APPA and provided support for the factorial/structure validity of the APPA's scores. Results also present initial evidence of discriminant validity and support the applicability of the instrument across demographics. Overall, these findings suggest Adlerian counselors can confidently use the APPA as a tool to conceptualize clients.
Confronting Convergence: Are Higher Education Administrators Using a Strategic Planning Approach to Mass Communication Curriculum Convergence?
Professors in mass communications departments of higher education institutions continue to search for the best way to prepare graduates for the ever-changing world of print, broadcast, and online media. Business administration theories have long been used in other areas, including education. While some application of strategic planning has been documented with regards to education, there is not much to reference in this area. The study investigated the use of strategic planning in developing a course of action for curriculum convergence in mass communication programs. The study used a purposive sample to determine if administrators are utilizing this method as a part of curriculum convergence. The results indicated a use of this method among institutions involved in curriculum convergence.
Connecting the Circuit: Analyzing Jurors' Cognitive Gaps and Damage Awards in Patent Infringement Trials
Patent litigation is notorious for the technicality of evidence and the rhetoric of experts. Citizens selected to serve on the jury have no specialized training and have rarely been exposed to the technology or the patent process. This study provides insight into the field of jury decision-making in complex patent cases by analyzing the cognitive gaps and the tactics used by jurors to minimize them. Additionally, the study examines the justifications for the damage awards jurors provide. This analysis focused on jurors engaged in mock trial patent deliberations. The story model and sensemaking theory serve as the theoretical framework of this research and provide a structure for support and a lens for analysis. The results indicate that jurors rely on three distinct and dichotomous topologies when navigating cognitive gaps. Searching for answers either individually or as a group, relying on lists or stories, and turning to facts or emotions, jurors navigate through their uncertainty. Through the line-by-line analysis of mock jury transcriptions, three continuums regarding damage justifications emerged. Jury members found themselves navigating uncertainty versus certainty, rationality versus irrationality, and facts versus emotions. The theoretical implications broaden the story model to include cognitive gaps in all phases and increase the model's efficacy in patent litigation through the addition of a fourth phase. This study also confirms and enhances the use of sensemaking to describe the jury decision-making process. The results of this study should be applied practically to the field of patent litigation. Results should be used to create a user-friendly environment where the high stakes of litigation demand increased juror understanding and are critical to justice.
Consensus Building in Sensor Networks and Long Term Planning for the National Airspace System
In this thesis, I present my study on the impact of multi-group network structure on the performance of consensus building strategies, and the preliminary mathematical formulation of the problem on improving the performance of the National Airspace system (NAS) through long-term investment. The first part of the thesis is concerned with a structural approach to the consensus building problem in multi-group distributed sensor networks (DSNs) that can be represented by bipartite graph. Direct inference of the convergence behavior of consensus strategies from multi-group DSN structure is one of the contributions of this thesis. The insights gained from the analysis facilitate the design and development of DSNs that meet specific performance criteria. The other part of the thesis is concerned with long-term planning and development of the NAS at a network level, by formulating the planning problem as a resource allocation problem for a flow network. The network-level model viewpoint on NAS planning and development will give insight to the structure of future NAS and will allow evaluation of various paradigms for the planning problem.
