The Relationship Among Teacher Expectations, Teacher Attitudes Toward the TAAS, and Student Achievement (open access)

The Relationship Among Teacher Expectations, Teacher Attitudes Toward the TAAS, and Student Achievement

Accountability is a major issue in education and in Texas, the TAAS test is used to indicate performance of students, teachers, campuses, and districts. The stakes are high for students, as performance on this test has determined whether they progress to another grade and whether they will receive a diploma. Most research studies focus on relationships between the teacher and individual students or groups of students, but not classrooms. Expectations and high stakes testing are central within the educational process, and their relationship on student achievement should be investigated, especially since no studies on teacher attitudes toward the TAAS test have been found. This correlational study measured teacher attitudes toward the TAAS and teacher expectations for students through data collected from a survey. Student achievement information was collected from averaged Texas Learning Index scores for students by classroom over a two year period. The sample consisted of 22 4th, 8th, and 10th grade reading and/or math teachers who had taught in the same Texas mid-sized, rural school district for at least two years. Frequency, percent, mean, and standard deviation were used to analyze the responses on the survey. A median score distinguished between high/low expectations and between positive/negative attitudes toward …

Psychometric Development of the Adaptive Leadership Competency Profile (open access)

Psychometric Development of the Adaptive Leadership Competency Profile

This study documented the psychometric development of the Adaptive Leadership Competency Profile (ALCP). The ALCP was derived from a qualitative database from the National Science Foundation project (NSF 9422368) and the academic body of literature. Test items were operationalized, and subject matter experts validated 11 macro-leadership competencies and 65 items. Rasch rating scale measurement models were applied to answer the following questions: (a) How well do the respective items of the ALCP fit the Rasch rating scale measurement model for the 11 scales of the ACLP? (b) How well do the person's abilities fit the Rasch rating scale measurement model, using the 11 scales of the ALCP? (c) What are the item separation and reliability coefficients for the 11 ALCP scales? (d) What are the person separation and reliability coefficients for the 11 ALCP scales? This study also sought to discern whether the ALCP could predict leader effectiveness as measured by the likelihood ratio index and frequency of correct predictions indices. The WINSTEPS and LIMDEP programs were used to obtain Rasch calibrations and probit estimates, respectively. The ALCP profiles the frequency and intensity of leadership behavior. Composite measures were calculated and used to predict leadership effectiveness. Results from this study …

Haiku Seasons (open access)

Haiku Seasons

Haiku Seasons is a choral work that uses several haiku to portray moments in nature. Spread throughout the performance space, four choirs (SATB, 3/part) depict larger parts of the pastoral scene (i.e., mountains, the moon, etc.). Soloists depart from the choirs in order to perform solo, duo, trio, and quartet passages, which take place throughout the work. If enough singers are available, individual soloists may be used. The soloist groups display the more intimate moments of the scenes (i.e., sparrows, a blade of grass, etc.). The intent of Haiku Seasons is to create an image of nature isolated from human interaction. Thus, the image is a pastoral setting with many independent parts all coexisting in a relatively silent world. I combine aspects of tonality, time, space, and silence to create this image.

Assessment of the Effects of Interpersonal Openness and Coping Resources on the Psychological Sequelae of Traumatic Victimization (open access)

Assessment of the Effects of Interpersonal Openness and Coping Resources on the Psychological Sequelae of Traumatic Victimization

The present study tested a model addressing whether interpersonal Openness and interpersonal and intrapersonal Coping Resources mediated the relationship between interpersonal Victimization and the Psychological Symptoms women experience as a result of these traumas. Victimization indicators (physical violence, sexual assault, psychological abuse, and revictimization), Coping indicators (optimism, self-esteem, private self-consciousness, social network and therapy), Openness indicators (self-silencing, communal orientation, trust, self-monitoring, and network orientation), and Psychological Symptoms indicators (global distress, dissociation, and suicidal ideation) were examined separately for African American (n = 245), Euro-American (n = 185), and Mexican American (n = 202) women. Structural Equation Modeling revealed that for African American and Euro-American women, Openness partially mediated the victimization-distress relationship. The model for Mexican Americans was the most complex with Openness and intrapersonal Coping fully mediating the psychological effects of victimization. Approximately 50% of the variance in psychological symptoms resulting from victimization was predicted by this model for African American and Euro-American women; over 80% of the variance was predicted for Mexican Americans. Thus, the importance of Openness to relationships in alleviating the psychological sequelae following interpersonal victimization was underscored by the results. Similarities and differences between these models are discussed. Implications of the results for future research and …

Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population (open access)

Concurrent Validity of the Wide Range Assessment of Memory and Learning and the Woodcock-Johnson Tests of Cognitive Ability-Revised with a Neurologically Compromised Pediatric Population

The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation …

Dynamic Grid-Based Data Distribution Management in Large Scale Distributed Simulations (open access)

Dynamic Grid-Based Data Distribution Management in Large Scale Distributed Simulations

Distributed simulation is an enabling concept to support the networked interaction of models and real world elements that are geographically distributed. This technology has brought a new set of challenging problems to solve, such as Data Distribution Management (DDM). The aim of DDM is to limit and control the volume of the data exchanged during a distributed simulation, and reduce the processing requirements of the simulation hosts by relaying events and state information only to those applications that require them. In this thesis, we propose a new DDM scheme, which we refer to as dynamic grid-based DDM. A lightweight UNT-RTI has been developed and implemented to investigate the performance of our DDM scheme. Our results clearly indicate that our scheme is scalable and it significantly reduces both the number of multicast groups used, and the message overhead, when compared to previous grid-based allocation schemes using large-scale and real-world scenarios.

Synthesis and characterization of molecules for electron transfer research. (open access)

Synthesis and characterization of molecules for electron transfer research.

Dimethoxynaphthalene (donor) and quinone (acceptor) have been chosen as a suitable redox pair and are bonded to either permethylated silane chains or corresponding permethylated alkyl chains to form Acceptor-(Bridge)-Donor molecules. The idea that the s-delocalization phenomenon of silane chains may greatly facilitate ET reactions will be tested. The starting material for the donor precursor, 4-(1,4-dimethoxynaphthyl)bromocyclohexane, was 1,4-naphthoquinone. After methylation and bromination, the Grignard reagent of the resulting bromide was reacted with cyclohexanedione, mono ethylene ketal. The resulting alcohol was changed to the donor precursor through the following functional group transformation steps: dehydration, hydrogenation, deketalization and bromination. 1,4-Dibenzyloxybromobenzene, the precursor for the acceptor, was synthesized from 1,4-hydroquinone through bromination and benzylation. The connection of the two precursors and either permethylated silane chains or permethylated alkyl chains will give the final target molecules for ET research. Progress on this is included.

Three Voices for voices, woodwind, percussion, and string instruments (open access)

Three Voices for voices, woodwind, percussion, and string instruments

Composed for soprano, tenor, and baritone voices, woodwind, percussion, and string instruments, Three Voices is a polyglotic work that includes German, Chinese, and Spanish texts. The texts are chosen from Brecht Bertolt's Das Schiff, Po Chu I's Lang T'ao Sha, and Frederico Garcia Lorcá's Mar. Significant features of the piece are 1) application of Chinese operatic singing methods to vocal material in the sections that use Chinese text, 2) use of western instruments to emulate the sound of certain Chinese instruments, and 3) employment of Sprechstimme and dramatically inflected speech to create theatrical effects and highlight the sections that use German and Spanish texts.
