The Impact of the Development of the Fortepiano on the Repertoire Composed for It From 1760–1860

The Impact of the Development of the Fortepiano on the Repertoire Composed for It From 1760–1860

Date: August 2012
Creator: Lin, Chao-Hwa
Description: The relationship between piano manufacturer and composer is interactive, and consequently both compositions and performance styles evolved organically due to this relationship. Early on, the instrument had more influence on the composer, whereas with the instrument’s establishment, composers began to exert more influence on the subsequent development of the instrument through their requests of manufacturers. The relationship between pianist-composers and manufacturers is important for pianists to study and understand, as well as the actual sound of a composer’s fortepiano and the way he performed on it. Through studying the development of the piano and the relationship between manufacturers and composers, pianists can reinterpret compositions before the mid nineteenth century, such as Mozart, Beethoven, Dussek, Chopin, and Liszt, using their knowledge of the aforementioned to bring a different perspective to their performances on the modern piano. There are numerous manufacturers and composers who made important contributions to the development of the piano. This dissertation focuses on selected pianist-composers and fortepiano manufacturers, and the impact of their relationship on piano literature before 1860.

The Impact of Training on Employee Advancement

The Impact of Training on Employee Advancement

Date: May 2011
Creator: Bradley, Lori
Description: In recent years, organizations have invested increasing financial and labor-related resources on employee training. The assumption is that training will benefit the organization through improved performance which will result in greater efficiency, greater customer satisfaction and, ultimately, increased revenue and profits. Further, employees are assumed to benefit because their improved performance should lead to career advancement and increased compensation. However, measuring the effect of training on employee performance has been problematic due to the difficulty of isolating the effect of training from other human resource management practices and environmental and organizational influences. Hierarchical multiple regression analyses were used to test a model for predicting merit pay increase, job promotion and performance ratings from measures of general and finance training, as well as employee tenure, gender, educational level and organizational level. It was found that while significant contributions (i.e., betas) were made by finance and general training for performance ratings, promotion and merit pay increase, they did not increase the variance accounted for by tenure, organizational level and gender.

The Impact of Training on the Frequency of Internal Promotions of Employees and Managers

The Impact of Training on the Frequency of Internal Promotions of Employees and Managers

Date: August 2010
Creator: West, Lindsey Straka
Description: In this study, the relationship between formal training opportunities and internal promotions in organizations was examined in order to support the value of organizations investing in employees through training opportunities, as training is often seen as an expense to be cut in difficult times. Differences between general and specific training topics on the impact of frequency of promotion in an organization were addressed, as well as assessing differences between employees and managers. Training allows for a more capable workforce and pool of employees to pull from when an organization needs to hire. Hiring from within can save time, money, and allow for a proven person-organization fit that hiring from the external workforce cannot provide. The archival data used in the study were from the National Organizations Survey, 1996-1997 which included organizations of all sizes and forms. The analyses produced mixed support for the hypotheses. Significant relationships were found between hours of formal training and frequency of promotions of employees, and between importance of training in promotions and frequency of promotions for managers. Multiple regressions revealed that the hypothesis predicting that increased hours of training focused on general skills would positively contribute to promotion rates was not supported for either employees ...

Impact of Video Presentation Features on Instructional Achievement and Intrinsic Motivation in Secondary School Learners

Impact of Video Presentation Features on Instructional Achievement and Intrinsic Motivation in Secondary School Learners

Date: December 2012
Creator: Bland, Ronald B.
Description: This study analyzed instructional achievement and intrinsic motivation among 21st century secondary students utilizing a video lecture incorporating both student reaction cutaway images and immediate content interaction within the lecture. Respondents (n = 155) were from multiple classes and grade levels at a suburban Texas high school. Four groups of students viewed the identical lecture with differing video and content interaction treatments. Students responded to a pretest/posttest survey to assess academic achievement in addition to an intrinsic motivation instrument to assess student interest. Group one (the control group) viewed the 12 minute lecture without enhancement. A second group viewed the identical lecture with student reaction shots inserted in the video. Another group viewed the lecture with content question intervention inserted into the video. The final group saw the lecture with the student reaction shots and content question intervention combined in the video. A repeated measures multivariate analysis of variance (MANOVA) was used to compare results from a 14 item pretest/posttest. Combined, the groups showed no significance (p = .069) indicating no associations were identified by the experiment. Although no association was identified, this may be a reflection of the generic nature of the video lecture and the lack of association ...

Impacts of Comprehensive Climate and Energy Policy Options on the U.S. Economy

Impacts of Comprehensive Climate and Energy Policy Options on the U.S. Economy

Date: July 2010
Creator: Center for Climate Strategies
Description: This study compiles and updates the findings of 16 comprehensive state climate action plans and extrapolates the results to the nation. The study then takes those results and using a widely accepted econometric model projects the national impact of these policies on employment, incomes, gross domestic product (GDP) and consumer energy prices. Finally, using the bottom-up data developed by the states and aggregated here, the study models the national impact of major features of the Kerry-Lieberman climate bill under consideration in Congress in 2010. These state action plans and supporting assessments were proposed by over 1,500 stakeholders and technical work group experts appointed by 16 governors and state legislatures to address climate, energy and economic needs through comprehensive, fact-based, consensus-driven, climate action planning processes conducted over the past five years with facilitative and technical assistance by the Center for Climate Strategies. Findings show potential national improvements from implementation of a top set of 23 major sector-based policies and measures drawn from state plans.

Impacts of Postmodernity Factors on the Association Between Maternal Distress and Children's Delinquency Among Low-income Families

Impacts of Postmodernity Factors on the Association Between Maternal Distress and Children's Delinquency Among Low-income Families

Date: December 2012
Creator: Bessa, Yawo
Description: This study investigates the effects of postmodern factors on the relationship between maternal distress and children's delinquency. It seeks to understand the factors associated with distress levels of mothers whose children exhibit delinquency in order to potentially decrease the cost associated with mental health problems especially in mothers. Another goal of this study is to contribute to the sociological analysis of mental health problems which seem to be the reserved domain of the discipline of psychology and related subfields. The data came from the third wave of the 3-city study with N = 1835. The ages of the children range from 5 to 18 years old. The analysis of the data using regression analysis suggests children's delinquency significantly affects maternal distress in mothers. The study also indicates postmodernity factors did not moderate the association between maternal distress and children's delinquency. However, postmodern factors have significant, separate, and direct effects on maternal distress. For example, employment and religion have positive influences on maternal distress. The research points toward weakness in the postmodern perspective. It also underlines the importance of a sociological approach to the assessment and treatment of distress problems among mothers with low-income. Agencies working with low-income families should integrate ...

Implementation of a Therapy Group for Wives of Veterans with Posttraumatic Stress Disorder: Development and Preliminary Outcomes

Implementation of a Therapy Group for Wives of Veterans with Posttraumatic Stress Disorder: Development and Preliminary Outcomes

Date: May 2011
Creator: Reck-Gordy, Jennifer K.
Description: The purpose of this study was to develop a manualized therapy group for wives or significant others of veterans with posttraumatic stress disorder and to evaluate its effectiveness in reducing wives' psychological symptoms. A second aim of the study was to determine if women's involvement in the wives group resulted in decreases in their husbands' PTSD symptoms. Women recruited for the study were administered pre-test measures during a screening session. They then participated in a 9-session manualized therapy group designed by the researcher that included psychoeducational, process, and support components. Examples of group topics included psychoeducation regarding PTSD, assertiveness and communication, intimacy, self-care, and stress management. After completing the group sessions, participants were asked to complete post-test measures. Other factors explored in this study included marital satisfaction, perceived social support, general satisfaction with the group, and demographic variables. Results indicated that wives who participated in the group treatment exhibited significant decreases in secondary stress symptoms and increases in marital satisfaction from pre-test to post-test. The majority of participants also reported high levels of satisfaction with the group process. Therefore, it appears that the group protocol presented in this study could be a useful tool in the treatment of wives of ...
