Correcting the Record: a Comparison of Vladimir Ashkenazy’s Urtext-based Edition of Pictures at an Exhibition with Orchestration By Ravel and Stokowski

Description: Modest Mussorgsky (1839-1881) never published his piano suite, Pictures at an Exhibition. The first publication of the Pictures was Nikolai Rimsky-Korsakov’s (1844-1908) piano edition in 1886, five years after Mussorgsky’s death. Among several piano editions of Pictures, Manfred Schandert’s urtext piano edition of 1984 has shed new light on the piano suite. The urtext edition is based on a facsimile of Mussorgsky’s autograph, and Schandert’s authoritative urtext contains all of Mussorgsky’s musical indications that previous editions neglected to include. Previous orchestrations based on less comprehensive editions include well-known orchestrations by Maurice Ravel (1875-1937) and Leopold Stokowski (1882-1977). Vladimir Ashkenazy (b. 1937), on the other hand, derived his orchestration directly from the Schandert edition. In this study I argue that Ashkenazy offers “corrections” to his predecessors, Ravel and Stokowski, whose orchestrations differ—at times radically—from Mussorgsky’s autograph. This dissertation thus will explore the significant features of Ashkenazy’s orchestration in relation to the urtext edition by comparing it to the orchestrations of Ravel and Stokowski. In an age of attempts to present “authentic” versions of past music, Ashkenazy’s orchestration provides an authenticity that other orchestrations lack. Ashkenazy’s orchestration of Pictures at an Exhibition provides conductors an alternative performance option that is both effective and more closely related to Mussorgsky’s autograph.

Cross-measure Equivalence and Communicability in the Assessment of Depression: a Fine-grained Focus on Factor-based Scales

Description: Depression is heterogeneous, however, depression measures conceptualize it as homogeneous. To help fulfill NIMH's strategic plan to focus on components of depression, this study analyzed the psychometrics of factor-based subscales in the BDI-II, CES-D, IDAS, and IDS. CCA was also used to explore redundancy across measures. Using a diverse sample of symptomatic undergraduates, this study found the IDAS to be the best measure, with complete DSM-IV symptom coverage and psychometrically sound subscales. The other measures did not have consistent subscales or coverage of symptoms. Furthermore, CCA revealed low levels of redundancy across measures. These results serve to disabuse the field of a perception that different measures of equivalently measure depression. Conversion tables were provided to empirically compare scores from different measures.

Data Compression Using a Multi-residue System (Mrs)

Description: This work presents a novel technique for data compression based on multi-residue number systems. The basic theorem is that an under-determined system of congruences could be solved to accomplish data compression for a signal satisfying continuity of its information content and bounded in peak-to -peak amplitude by the product of relatively prime moduli,. This thesis investigates this property and presents quantitative results along with MATLAB codes. Chapter 1 is introductory in nature and Chapter 2 deals in more detail with the basic theorem. Chapter 3 explicitly mentions the assumptions made and chapter 4 shows alternative solutions to the Chinese remainder theorem. Chapter 5 explains the experiments in detail whose results are mentioned in chapter 6. Chapter 7 concludes with a summary and suggestions for future work.

Data Envelopment Analysis: Measurement of Educational Efficiency in Texas

Description: The purpose of this study was to examine the efficiency of Texas public school districts through Data Envelopment Analysis. The Data Envelopment Analysis estimation method calculated and assigned efficiency scores to each of the 931 school districts considered in the study. The efficiency scores were utilized in two phases. First, the school district efficiency scores were combined with school district student achievement to evaluate effectiveness with efficiency. A framework was constructed to graph the scores on an x-axis of student achievement scores and a y-axis of efficiency scores to further illustrate the data. The framework was evaluated with the full statewide sample and with school districts categorized into similar peer groups. Then, using variables selected from related scholarly literature, a regression analysis identified which factors impacted school district efficiency statewide. The non-discretionary variables included in the study were total student enrollment, the percentage of non-white students and the percentage of economically disadvantaged students. The discretionary variables selected included the teacher-to-student ratio, teachers’ average years of experience, the percentage of teachers with master’s degrees and the average teacher base salary. Amongst the seven factors selected for regression analysis, five statistically significant variables were identified as impacting statewide school district efficiency. All three non-discretionary variables were identified as statistically significant on efficiency and included total student enrollment, the percentage of non-white students and the percentage of economically disadvantaged students. Two discretionary factors showed statistically significant effects on efficiency which included teachers’ average years of experience and the percentage of teachers with master’s degrees. The teacher-to-student ratio and the average teacher base salary were ineffective in predicting efficiency. This study contributed to the understanding on educational efficiency. Data Envelopment Analysis has been employed mainly in the private sector to analyze efficiency in economics and business organizations. This study added to the educational research ...

Decentering and the Theory of Social Development

Description: The concept of decentering originated with Piaget, who defined decentering as a feature of operational thought, the ability to conceptualize multiple perspectives simultaneously. Feffer applied Piaget’s concept of decentering to the cognitive maturity of social content. This study used Feffer’s Interpersonal Decentering scoring system for stories told about TAT pictures to investigate the developmental hierarchy of decentering for children and adolescents. The participants originated from the Berkeley Guidance Study, a longitudinal sample of more than 200 individuals followed for more than 60 years by the Institute of Human Development at the University of California, Berkeley. The hypotheses tested were: (1) chronological age will be positively related to Decentering as reflected in Feffer’s Interpersonal Decentering scores obtained annually between ages 10 and 13 and at 18; (2) children born into higher class homes would have higher Age 12 Decentering scores; (3) children born later in birth order will have higher Age 12 Decentering scores; (4) children whose parents were observed to have closer bonds with their children at age 21 months will have higher Age 12 Decentering scores; (5) adolescents with higher scores from the Decentering Q-sort Scale (derived from adolescent Q-sorts) will have higher Age 12 Decentering scores; and (6) participants who have higher Age 12 Decentering scores will self-report higher CPI Empathy scale scores at Age 30. A repeated measures ANOVA tested Hypothesis 1. Pearson product-moment correlation coefficients tested Hypotheses 2-6. Age and Decentering scores were unrelated, as was birth order; social class findings were mixed. Parents’ bonds with child and Age 12 Decentering were negatively correlated (closer bonds predicted higher Decentering), as were Age 12 Decentering and Age 30 Empathy (higher early Decentering predicted lower adulthood Empathy). Girls (age 12) tended to decenter more consistently and had higher Decentering scores than boys.

Design, Synthesis and Screening of Homoleptic and Heteroleptic Platinum(ii) Pyridylazolate Complexes for N-type Semiconducting and Light-emitting Devices

Description: A series of heteroleptic and homoleptic platinum(II) complexes has been synthesized and characterized towards their use in thin film devices such as organic light-emitting diodes (OLEDs) and organic thin film transistors (OTFTs). Pyridylpyrazolate- and pyridyltetrazolate-containing ligands were selected due to their structural rigidity and ease of functionalization. Single-crystal x-ray diffraction studies of two selected heteroleptic complexes show strong aggregation with preferential stacking into vertical columns with a varying degree of overlap of the neighboring square planar molecular units. It is shown that the close proximity of the molecules to one another in the stack increases semiconducting character, phosphorescence quantum yields, and shorter radiative lifetimes. The potential for these materials towards incorporation into high-efficiency doping free white OLEDs (DFW-OLEDs) for solid-state lighting and display applications has been realized and will be expanded upon by present and future embodiments of materials in this thesis.

Developing Oral Reading Fluency Among Hispanic High School English-language Learners: an Intervention Using Speech Recognition Software

Description: This study investigated oral reading fluency development among Hispanic high school English-language learners. Participants included 11 males and 9 females from first-year, second-year, and third-year English language arts classes. The pre-post experimental study, which was conducted during a four-week ESL summer program, included a treatment and a control group. The treatment group received a combination of components, including modified repeated reading with self-voice listening and oral dictation output from a speech recognition program. Each day, students performed a series of tasks, including dictation of part of the previous day’s passage; listening to and silently reading a new passage; dictating and correcting individual sentences from the new passage in the speech recognition environment; dictating the new passage as a whole without making corrections; and finally, listening to their own voice from their recorded dictation. This sequence was repeated in the subsequent sessions. Thus, this intervention was a technology-enhanced variation of repeated reading with a pronunciation dictation segment. Research questions focused on improvements in oral reading accuracy and rate, facility with the application, student perceptions toward the technology for reading, and the reliability of the speech recognition program. The treatment group improved oral reading accuracy by 50%, retained and transferred pronunciation of 55% of new vocabulary, and increased oral reading rate 16 words-correct-per-minute. Students used the intervention independently after three sessions. This independence may have contributed to students’ self-efficacy as they perceived improvements in their pronunciation, reading in general, and reported an increased liking of school. Students initially had a very positive perception toward using the technology for reading, but this perception decreased over the four weeks from 2.7 to 2.4 on a 3 point scale. The speech recognition program was reliable 94% of the time. The combination of the summer school program and intervention component stacking supported students’ gains in oral ...

Development of Disordered Eating in Undergraduate Women: a Test of the Re-conceptualized Objectification Process

Description: The eating disorder literature has long suggested that sociocultural experiences specific to women influence development of bulimic pathology; however, models have differed on the type of experiences that are important and what other variables interact with these experiences to lead to eating pathology. Broader sociocultural theory and objectification theory represent two such differing models, and more recently Moradi hypothesized that integrating elements from both models would provide a better picture of eating disorder development. The present study, therefore, sought to compare these three different models of bulimic pathology development to determine which one provides the best explanation for bulimic outcomes. The sample consisted of 682 undergraduate women between the ages of 18 and 24, recruited from a large southwestern university. Data were collected on-line using a series of questionnaires to measure the constructs of interest and analyzed using structural equation modeling. All three models fit the data well and explained approximately 50% of bulimic outcomes; however, the model based on Moradi’s integrated model provided the most information about the relationships between constructs within the model. The development of bulimic symptomatology appears best explained by a model that focuses on the sociocultural experience of pressures about weight and body size, but also integrates aspects of objectification theory as well. Future research, however, is needed to determine if sexually objectifying experiences, if measured differently, affect women’s development of eating pathology along with pressures.

Differences in Experiences and Outcomes of Transfer and Native Students in an Elementary Education Program: an Exploratory Study

Description: This research targeted elementary education graduates of a large Southwestern university who were transfer students, and compared them to native students on selected variables. These variables included retention in teaching, and perception of supports and obstacles at the university. The sample consisted of 143 respondents: 73 native and 70 transfer students. Data were collected through submission of online surveys and through postal mail. Quantitative and qualitative analyses were used to answer the research questions. Astin’s input-environment-outcome model provided the conceptual and theoretical framework for this study. Native and transfer students considered student teaching to be the “most helpful” course or service during their time at the university, yet both felt they lacked elements of preparation for teaching in the real world. Transfer students reported the following as supports during their transition from community college to university: academic advising, finances, support network, and the university. They reported these obstacles: university bureaucracy, credit transfer, expenses, and adapting to campus. There was no significant difference between the two groups’ intentions to remain in teaching (p = .249), and a statistically non-significant higher percentage of transfer students than native students reported to be teaching at the time of survey completion (p = .614). The findings support further inquiry into support systems for transfer students, as well as further examination of teacher preparation curricula.

Drive Level Dependence of Advanced Piezoelectric Resonators

Description: Resonators are one of the most important parts of electronic products. They provide a stable reference frequency to ensure the operation of these products. Recently, the electronic products have the trend of miniaturization, which rendered the size reduction of the resonators as well [1]. Better design of the resonators relies on a better understanding of the crystals' nonlinear behavior [2]. The nonlinearities affect the quality factor and acoustic behavior of MEMS (Micro-Electro-Mechanical-System) and nano-structured resonators and filters [3]. Among these nonlinear effects, Drivel Level Dependence (DLD), which describes the instability of the resonator frequency due to voltage level and/or power density, is an urgent problem for miniaturized resonators [2]. Langasite and GaPO4 are new promising piezoelectric material. Resonators made from these new materials have superior performance such as good frequency-temperature characteristics, and low acoustic loss [2]. In this thesis, experimental measurements of drive level dependence of langasite resonators with different configurations (plano-plano, single bevel, and double bevel) are reported. The drive level dependence of GaPO4 resonators are reported as well for the purpose of comparison. The results show that the resonator configuration affects the DLD of the langasite resonator. Experiments for DLD at elevated temperature are also performed, and it was found that the temperature also affects the DLD of the langasite resonator.

The Effect of Naturalistic Behavior Strategies on the Quality of Social Interactions for Children with Autism

Description: Autism is primarily a social disorder and deficits in social?orienting may be responsible for the failure of children with autism to initiate critical social behaviors. The purpose of this research was to improve the quality of social interactions of children with autism by implementing naturalistic behavior strategies intervention utilizing a multiple baseline design across four participants. Naturalistic behavior strategies comprised a comprehensive package of integrated components including: (a) intervention in the child’s natural environment; (b) child-initiated play activities ; (c) prompts to emit language; (d) shaping for all vocal approximations and (e) delivery of natural reinforcement with embedded social interactions to maintain learned behavior. In addition to intervention, generalization of child behaviors was assessed across untrained parents and/or caregivers in the same environment. Results indicated the effectiveness of naturalistic teaching strategies package in increasing (a) the frequency of vocal mands for all children, (b) the number of times that children initiated social engagement during manding, and (c) intervals of nonverbal dyadic orienting. These skills generalized across two untrained caregivers in the same clinical setting without any training from the interventionist. Two parents required training during the generalization phase in order for their child’s behaviors to maintain at levels demonstrated during the intervention phase. Implications for future research and clinical practice are discussed.

The Effect of Three Compositional Structures on the Compositional and Instructional Self-efficacy of Pre-service Music Teachers

Description: The purpose of this study was two-fold: 1) to compare the effects of three different composition tasks with varying degrees of structure on pre-service music teachers’ creative self-efficacy as composers and their instructional self-efficacy as pedagogues of composition; and 2) to describe through pre-service music teachers’ talk perceptions of composition and their experiences completing the three composition tasks. Participants (N = 29) were music education majors from three different sized universities in the northern-central region of the United States. At the beginning of the study, the participants answered a researcher-design self-efficacy questionnaire that measured (a) their self-efficacy as composers and (b) their self-efficacy as teachers of composition. Next, they composed three compositions of various task structures (unstructured, poem, and rhythm). Immediately after completing each task they again completed the self-efficacy questionnaire. Statistically significant mean differences between the pre-task administration of the measuring instrument and all three composition tasks were found for the pre-service teachers’ compositional self-efficacy. Statistically significant mean differences were also found between the unstructured task and the rhythm task, but not between the rhythm and poem tasks or the unstructured and poem tasks. For the pre-service teachers’ self-efficacy as pedagogues of composition question, the results were also statistically significant between the pre-task administration of the measuring instrument and all three composition tasks. Statistically significant mean differences were also found between the unstructured task and the rhythm task as well as the poem and rhythm tasks, but not between the unstructured and poem tasks. Additional data were gathered through semi-structured one-on-one interviews. Through their talk the pre-service music teachers commented that they enjoyed the overall composition process. This experience also seemed to challenge the participants’ assumptions about composition and appeared to make creative experiences more tenable and relevant to their future classroom experiences. The results of this study suggest ...

The Effects of Increasing Rates of Reinforcement Through an Alternative Fluent Behavior on the Acquisition and Extinction of Behavior in Dogs

Description: The purpose of the present study was to experimentally investigate the effects of interspersing the opportunity to perform a fluent behavior during the acquisition of a new behavior. The experimenter trained left and right paw movements in domestic canines using a multiple treatment design. One paw movement was trained with a typical shaping procedure while the other was trained with an opportunity to perform a fluent behavior, touching the dog’s nose to a plastic disc, following each successive approximation in the shaping procedure. Two extinction phases were implemented during the experiment. The results showed that higher rates of reinforcement were achieved primarily following changes in criteria for reinforcement for the behavior in acquisition. There were no effects on rate of acquisition of the behavior, but adding an alternative fluent behavior may have slowed the differentiation between the reinforced behavior and alternative behaviors for one dog. The behavior trained with the addition of an alternative fluent behavior extinguished more quickly than in the control condition and extinguished at similar rates to the opposite leg movement. This suggests that the technique of offering an alternative fluent behavior may facilitate the chaining of the opposite behavior with the behavior targeted for reinforcement.

The Effects of Price and Durability on Individual Discounting Functions When Purchasing Hypothetical Goods in a Simulated Internet Store

Description: Online shopping has rapidly expanded in the last decade. Online shopping necessarily imposes delays on all transactions. Behavior analysis has long studied the effects of delay on choice. Additionally, a number of researchers are beginning to study consumer behavior using a behavior-analytic approach. The current study attempted to extend research focusing on consumer behavior in online contexts. The experimenters attempted to evaluate whether goods acquire functional properties and whether these properties influence consumer choice. The researchers were specifically interested in studying acquisition costs and durability and in simulating a natural online shopping environment. Results from the current study extend the findings showing that delay and price influence choice. The data from the current study provide mixed evidence for control by item durability.

Emotional and Cognitive Coping in Relationship Dissolution

Description: Romantic relationships are important for social development and can impact an individual’s functioning both positively and negatively, especially when the relationship breaks up. Emotional and cognitive coping strategies including emotion approach coping, avoidance, and rumination and variable response to expressive writing intervention were examined in relation to post-dissolution distress. Undergraduate participants randomized into two groups completed measures of cognitive and emotional coping variables and global distress, with the experimental group completing a three-session expressive writing protocol. Writing samples were rated for processing mode, or the degree of vague general statements. Avoidance and rumination demonstrated significant cross-sectional associations with Time 1 distress controlling for demographics and characteristics of the former relationship. Gender moderated the relationship between rumination and distress. Using a matched sub-sample, the groups did not differ on emotional coping variables or distress. Results demonstrate the importance of examining emotional coping strategies in conjunction with relationship dissolution.

The Emotional Needs of Mothers of Multiple Birth Children

Description: The purpose of this study was to assess the emotional support needs of mothers of multiple birth children based on administration of a survey the researcher developed. The survey consisted of 25 demographic items, six 6-point Likert scale items, and three open-ended questions. Likert scale items were based on amount of perceived emotional support mothers received in their environments at the time of survey administration. Open-ended questions addressed negative and positive aspects of parenting multiples and emotional support needs. The sample consisted of 171 mothers of multiple birth children from 23 states in the United States. Participants ranged in age from 20-50 years old with 38% not reporting age. Participants were 95.3% Caucasian, 0% African-American, 1.8% Asian, 0% Native American and 1.2% other; of these, 5.8% were Hispanic. We used demographic statistics and constant comparison to determine basic demographic characteristics of this sample and to identify emotional support needs of mothers of multiple birth children. We used Pearson product moment correlation to determine potential relationships between variables. Results indicated a statistically significant positive correlation between overall life satisfaction and partner satisfaction (r = .420, n = 170, p < 0.01). Therefore, mothers of multiples experience increased satisfaction with their lives when they receive greater support from partners. Also, results indicated a statistically significant positive correlation between partner satisfaction and partner caretaking responsibilities (r = .305, n = 169, p < 0.01). As partners of mothers of multiples increase contribution to caretaking of children, mothers demonstrate greater relationship fulfillment. Implications for mental health professionals working with mothers of multiple birth children are discussed.

The Enemy of My Enemy Is What, Exactly? the British Flanders Expedition of 1793 and Coalition Diplomacy

Description: The British entered the War of the First Coalition against Revolutionary France in 1793 diplomatically isolated and militarily unprepared for a major war. Nonetheless, a French attack on the Dutch Republic in February 1793 forced the British to dispatch a small expeditionary force to defend their ally. Throughout the Flanders campaign of 1793, the British expeditionary force served London as a tool to end British isolation and enlist Austrian commitment to securing British war objectives. The 1793 Flanders campaign and the Allied war effort in general have received little attention from historians, and they generally receive dismissive condemnation in general histories of the French Revolutionary Wars. This thesis examines the British participation in the 1793 Flanders campaign a broader diplomatic context through the published correspondence of relevant Allied military and political leaders. Traditional accounts of this campaign present a narrative of defeat and condemn the Allies for their failure to achieve in 1793 the accomplishments of the sixth coalition twenty years later. Such a perspective obscures a clear understanding of the reasons for Allied actions. This thesis seeks to correct this distortion by critically analyzing the relationship between British diplomacy within the Coalition and operations in Flanders. Unable to achieve victory on their own strength, the British used their expeditionary force in Flanders as diplomatic leverage to impose their objectives on the other powers at war with France.

Equivalence Classes of Subquotients of Pseudodifferential Operator Modules on the Line

Description: Certain subquotients of Vec(R)-modules of pseudodifferential operators from one tensor density module to another are categorized, giving necessary and sufficient conditions under which two such subquotients are equivalent as Vec(R)-representations. These subquotients split under the projective subalgebra, a copy of ????2, when the members of their composition series have distinct Casimir eigenvalues. Results were obtained using the explicit description of the action of Vec(R) with respect to this splitting. In the length five case, the equivalence classes of the subquotients are determined by two invariants. In an appropriate coordinate system, the level curves of one of these invariants are a pencil of conics, and those of the other are a pencil of cubics.

Evaluating the Effects of Video Modeling on the Frequency of Staff Use of Socially Embedded Consequences

Description: Previous research reports that individuals working with children with autism can positively affect social behavior through the use of socially embedded consequences. There is no research on training teachers to use socially embedded consequences. The current study had three purposes: to evaluate the effects of video modeling on teachers' embedded consequences, to evaluate the addition of feedback to increase effectiveness, and to evaluate the effects of the teacher's use of socially embedded consequences on other teacher behaviors. Results indicate that video modeling alone was not sufficient in changing teacher behavior and that the addition of feedback was necessary for meaningful teacher behavior change. Additionally, the increased used of socially embedded consequences had positive effects on teacher social engagement and indices of interest. A discussion of the results and suggestions for future research is also provided.

Event Centrality: Debunking the “Bad Science” Myth That Self-reported Posttraumatic Growth Does Not Reflect Positive Change

Description: Despite strong evidence supporting the existence of posttraumatic growth (PTG), some investigators question whether the construct measured by the Posttraumatic Growth Inventory (PTGI) is that of perceived growth or “actual” growth. In a replication of a recent investigation, the present study sought to refine the methodology used by employing the construct of event centrality. Due to its limited sample size, the results of this analysis did not provide strong evidence in support of the hypothesis that limiting analyses to individuals rating their trauma as high in event centrality improves the ability of the PTGI to reflect “actual” growth. However, results did support the idea that investigations of PTG conducted immediately following a trauma may be more reflective of a coping process, rather than growth. Further research is warranted to investigate the role of event centrality in posttraumatic growth, and the effect of time on the progression of growth following trauma.

An Examination of Preferences for Social Presence in Online Courses with Regard to Personality Type

Description: The purpose of this research was to examine the connections between personality types as illustrated by the Myers Briggs Type Indicator and the desire for social presence components within a technology based learning environment. Participants in the study were undergraduate and graduate students enrolled in an educational technology program at a public university in the State of Texas. The study employed a mixed-method qualitative approach that utilized a paired comparison evaluation, a personality assessment, and semi-structured interviews. Results showed that the components of organization and feedback were thought to best foster social presence in technology based learning environments and that there was no real difference between the personality types of introverts versus extroverts and judgers versus perceivers.

Factors Influencing Psychological Empowerment of Nurse Aides in Nursing Homes

Description: The purpose of this study is to identify predictors of psychological empowerment among nurse aides in nursing homes. Five structural factors (information exchange, decentralization of resources, co-worker support, supervisor support, and availability of training) and four control factors (age, sex, level of education, and race) are analyzed using multivariate linear regression to examine their effects on psychological empowerment. Two of the five structural factors, decentralization of resources and supervisor support, are shown to positively influence psychological empowerment. Nursing home managers can consider developing and implementing procedures that decentralize resources and demonstrate supervisor support in order to increase psychological empowerment. Based on the findings of this study theory and practice might benefit from additional study of decentralization of resources and supervisor support.
