The Effects of Cumulative Consumption Feedback On Demand For Money As A Commodity

The Effects of Cumulative Consumption Feedback On Demand For Money As A Commodity

Date: May 2001
Creator: Bailey, Kathleen
Description: Behavioral economic theory describes a relation between response requirement and magnitude of reinforcement, and combines these variables into one independent variable (unit price) affecting operant behavior. This study investigated the relative effects of cumulative feedback on consumption for money as a commodity. Subjects were exposed to ranges of unit prices with or without a cumulative feedback bar on the computer screen indicating monetary earnings. For all participants in this study, consumption of money was a decreasing function of unit prices and the results from the present study are consistent with the behavioral economic prediction that increasing the unit price of a commodity will decrease consumption of that commodity. Analyses of demand curves, elasticity coefficients and response rates suggested differences between Feedback and No Feedback groups, although these were small and not statistically significant. The small differences observed were consistent with a behavior strengthening effect of feedback.

Accent and Grouping Structures in the String Quartets of Béla Bartók

Accent and Grouping Structures in the String Quartets of Béla Bartók

Date: May 2001
Creator: Bocanegra, Cheryl D.
Description: The music of Béla Bartók is defined in part by its unique blend of rhythmic vitality and inventiveness, and his string quartets offer a glimpse into a consistency of technique evident throughout his compositional career. Bartók's rhythmic environments are primarily metrical, but many of his rhythmic configurations are placed in such a way as to potentially override established meter. It is necessary, therefore, to institute an analytical means by which the delineation and comparison of rhythmic structures both within and without the metrical context may be accomplished. An analytical method using Timepoint Accent Structures (TAS) allows for the comparison of rhythms resulting from patterns of accent produced by pitch onset, dynamic stress, articulation or any other accentual factors. Timepoint Grouping Structures (TGS) delineate the number of timepoints present in alternating groups/blocks in a texture, thereby allowing for the recognition of patterning created by these larger groups. By applying TAS and TGS analysis, relationships of rhythmic equivalency, rotation, retrograde, complementation, augmentation, diminution, subset, superset, exchange, compression and expansion are clearly confirmed in the string quartets. In addition, symmetrical structures and arithmetic progressions are discovered. In many ways, Bartók's rhythmic organization mimics his procedures of pitch structuring.

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

Date: August 2001
Creator: Laughlin, James Edwin
Description: This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items. While the ...

Thermochemical investigations of crystalline solutes in non-electrolyte solutions: Mathematical representation of solubility data and the development of predictive solubility equations in systems with specific and non-specific interactions.

Thermochemical investigations of crystalline solutes in non-electrolyte solutions: Mathematical representation of solubility data and the development of predictive solubility equations in systems with specific and non-specific interactions.

Date: May 2008
Creator: Zvaigzne, Anita Ilze
Description: Understanding the thermodynamic properties of multicomponent mixtures is of critical importance in many chemical and industrial applications. Experimental measurements become progressively difficult as the number of solution components increases -- producing the need for predictive models. Problems in development of predictive models arise if the mixture has one or more components that interact through molecular complexation or association. Experimental solubilities of anthracene and pyrene dissolved in binary systems containing one or more alcohols were measured in order to address this problem. Alcohols examined in this study were: 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol, and 1-octanol. In binary solvent mixtures containing only a single self-associating alcoholic solvent, the alkane cosolvents studied were: n-hexane, n-heptane, n-octane, 2,2,4-trimethylpentane, cyclohexane, methylcyclohexane, tert-butylcyclohexane. Predictive solubility equations were developed using mobile order theory. This approach differs from classical solution models by representing hydrogen bonding with a probability term rather than with expressions derived from stepwise equilibria or expressions to represent hypothetical solution aggregates. Results were compared with the predicted solubilities found from using expressions developed using the Kretschmer-Wiebe and Mecke-Kempter approaches for modeling associated solutions. It was found that the mobile order approach provided reasonably accurate predictions for the solute solubilities in the systems studied. The ...

The Effects of Positive Behavioral Supports in Schools since the Implementation of the Individuals with Disabilities Education Act of 1997 based on 2001 SLIIDEA Data

Date: August 2009
Creator: Miller, Cindy
Description: Congress in 1997 recognized that there were some issues and concerns that had emerged surrounding the Individuals with Disabilities Education Act (IDEA) and sought to address these issues and concerns by mandating a national evaluation on the implementation and progress toward improving outcomes for students with disabilities. The Study of the State and Local Implementation of the Individuals with Disabilities Education Act was designed to address how the amendments of IDEA were being implemented by states, school districts, and schools. This mixed methods study examined the first year of data collected from the six-year Study of the State and Local Implementation of IDEA (SLIIDEA) and analyzing 20 case studies that used interviews of special education personnel and principals, conducted at the local school level. Data from the national survey were examined in light of findings from the case studies. The case studies brought out the varying opinions on implementation success at the local level. Further case studies for each year of the study would be helpful in determining the level of implementation locally and the significant insights of local school personnel on whether these initiatives have worked.

A Change Agent in the Use of Continuing Online Distance Learning Technology

A Change Agent in the Use of Continuing Online Distance Learning Technology

Date: August 2009
Creator: Lawson, Cheryl L.
Description: Managers of public libraries have been presented with a new set of challenges in the day-to-day operations of public libraries. These include their ability to serve as change agents as they manage the use of continuing online distance learning (CODL) for staff. This online tool may provide staff opportunities for on-the-job learning, yet for managers and managerial staff little is known about how the tool impacts their role in light of the changes. This research investigates the perceptions of 103 Northeast Texas Library System managers and managerial staff about their role as a change agent in the use of CODL using an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to determine the outcome. Administrators from urban, suburban, and rural public libraries were surveyed using a General Training Climate Scale to explore three constructs: extent of the manager role, manager role, and use of CODL. Data analysis was performed using exploratory and confirmatory analysis to support the theoretical model. An altered model was tested and confirmed through model fit indices.

The relationship between racial discrimination induced anger and smoking among Black adolescents.

The relationship between racial discrimination induced anger and smoking among Black adolescents.

Date: August 2009
Creator: Miller, Aletha Rena
Description: This study explored whether a relationship exists between smoking behaviors and racial discrimination induced anger among Black adolescents. Participants consisted of 134 Black adolescents from 14 to 18 years of age who frequently visited a recreation center in the Northeast. Forty-four participants were males and 90 were females. All participants were administered a modified version of the CAGE questionnaire, a background information questionnaire, and a measure designed to assess the extent to which they feel angry because they had been discriminated against. Only age was found to be predictive of scores on the CAGE. Only gender was found to be predictive of smoking frequency. The Black Anger Measure (BAM) was significantly correlated with smoking behaviors. Some implications for theory, research and practice are suggested.

Formulaic sequences in English conversation: Improving spoken fluency in non-native speakers.

Formulaic sequences in English conversation: Improving spoken fluency in non-native speakers.

Date: August 2009
Creator: McGuire, Michael
Description: Native speakers often ignore the limitless potential of language and stick to institutionalized formulaic sequences. These sequences are stored and processed as wholes, rather than as the individual words and grammatical rules which make them up. Due to research on formulaic sequence in spoken language, English as a Second Language / Foreign Language pedagogy has begun to follow suit. There has been a call for a shift from the traditional focus on isolated grammar and vocabulary to formulaic sequences and context. I tested this hypothesis with 19 L2 English learners who received 5 weeks of task-based instruction and found substantial progress in oral fluency only for the experimental group. Differences between pretest and posttest oral fluency were examined by looking at the learners' speech rate and their mean length of run. Subjective evaluation of fluency by 16 native English judges confirmed the calculated measures.

Stratified item selection and exposure control in unidimensional adaptive testing in the presence of two-dimensional data.

Stratified item selection and exposure control in unidimensional adaptive testing in the presence of two-dimensional data.

Date: August 2009
Creator: Kalinowski, Kevin E.
Description: It is not uncommon to use unidimensional item response theory (IRT) models to estimate ability in multidimensional data. Therefore it is important to understand the implications of summarizing multiple dimensions of ability into a single parameter estimate, especially if effects are confounded when applied to computerized adaptive testing (CAT). Previous studies have investigated the effects of different IRT models and ability estimators by manipulating the relationships between item and person parameters. However, in all cases, the maximum information criterion was used as the item selection method. Because maximum information is heavily influenced by the item discrimination parameter, investigating a-stratified item selection methods is tenable. The current Monte Carlo study compared maximum information, a-stratification, and a-stratification with b blocking item selection methods, alone, as well as in combination with the Sympson-Hetter exposure control strategy. The six testing conditions were conditioned on three levels of interdimensional item difficulty correlations and four levels of interdimensional examinee ability correlations. Measures of fidelity, estimation bias, error, and item usage were used to evaluate the effectiveness of the methods. Results showed either stratified item selection strategy is warranted if the goal is to obtain precise estimates of ability when using unidimensional CAT in the presence of ...

A Cross-sectional and Longitudinal Study of Adolescents and Religion: Views of Risk and Resiliency

A Cross-sectional and Longitudinal Study of Adolescents and Religion: Views of Risk and Resiliency

Date: August 2009
Creator: Miesse, Colette Ann
Description: The research literature within the past decade has documented the importance of religiosity and spirituality in helping many adults around the world cope with major life stressors and events. Still, the role of religiosity and spirituality in adolescence is not well-known as research during this developmental period has been limited by sample size, homogeneity of samples, ethnic restrictions, and use of scales with few items. The goal of the current study is to identify and understand adolescent levels of religiousness and spirituality, as well as their roles on later social, emotional, and behavioral outcomes. The current study relied upon data from the National Longitudinal Study of Adolescent Health and utilized confirmatory factor analysis and structural equation modeling in order to generate models of the relationships between the various latent variables. The religiosity and spirituality factors in the current study adequately measure religious perceptions and practices of adolescents over time. These constructs also play a role in later emotional well-being and self-esteem. Analyses also found adequate predictive abilities in the other model factors of delinquency, psychological well-being, self-esteem, and the social support. It is concluded from this study that religiosity and spirituality are not interchangeable constructs, and that more robust measures ...

Reform and change in police education: Examining the variations in the top-down and bottom-up structures in the process of implementation.

Date: August 2009
Creator: Kapti, Alican
Description: This study examines the variations in the practice of implementation in different implementation structures using the case of police education reforms that were undertaken by the Turkish National Police (TNP) in 2001 and 2003. Differentiations and similarities in the top-down and bottom-up structures while practicing the process of implementation were investigated in this study. First, the study provides a comprehensive understanding of the process of implementation and structure of implementation. Second, the study introduces TNP education reforms and explains the reasons for the reform. Third, a quantitative approach is used to measure the success of the TNP educational reforms. Specifically, multiple regression analysis, one-way analysis of variance (ANOVA), and post hoc tests are used to clarify if police performance in the TNP has improved since the reforms. Fourth, the study uses a qualitative approach to find out how features associated with top-down or bottom up approaches were involved in the process of implementation of the educational reforms. Finally, based upon the views of the participants in the qualitative analysis, the study examines the variations in the practice of implementation between decision makers and the street level bureaucrats.
