User Modeling Tools for Virtual Architecture

User Modeling Tools for Virtual Architecture

Date: May 2003
Creator: Uppuluri, Raja
Description: As the use of virtual environments (VEs) is becoming more widespread, user needs are becoming a more significant part in those environments. In order to adapt to the needs of the user, a system should be able to infer user interests and goals. I developed an architecture for user modeling to understand users' interests in a VE by monitoring their actions. In this paper, I discussed the architecture and the virtual environment that was created to test it. This architecture employs sensors to keep track of all the users' actions, data structures that can store a record of significant events that have occurred in the environment, and a rule base. The rule base continually monitors the data collected from the sensors, world state, and event history in order to update the user goal inferences. These inferences can then be used to modify the flow of events within a VE.

Visual Cueing: Investigating the Effects of Text Annotation on Student Retention Rates

Visual Cueing: Investigating the Effects of Text Annotation on Student Retention Rates

Date: May 2003
Creator: Brown, Ron
Description: This Study examines the grades of students using study skill methods and those who do not. The experiment consists of giving the treatment group the opportunity to use well- known study techniques. The Control group could only read the material. Both groups were given ten minutes to read a pre-selected text. The text consisted of an 1,807 word lesson on the, "Technical Training Management System." Each group was given five minutes to take a twenty item quiz. Fifty-five students in the control group were limited to only reading the material. Fifty-six students in the treatment group could choose between highlighting, note-taking, and underlining. The results of the test scores were compared using a t - test for dependent samples. One week later, the same students in each group were re-tested, using the same quiz they had taken earlier. Students had five minutes to review study material. Study material for the treatment group included the same material they had annotated earlier. The Results from each group wascompared. Efforts were made to avoid potential flaws in previous studies, thereby producing more viable results. Results of this study indicate there is no significant difference between the grades of students who use the aforementioned ...

The Whole as a Result of Its Parts: Assembly in Aaron Copland's Score for  The Red Pony

The Whole as a Result of Its Parts: Assembly in Aaron Copland's Score for The Red Pony

Date: May 2003
Creator: McGinney, William Lawrence
Description: Aaron Copland's music for The Red Pony (1948-49), based on John Steinbeck's story collection, is probably the best known of his film scores. The effectiveness of The Red Pony score stems from Copland's belief that film music should be subordinate to the film it accompanies. Copland composed The Red Pony score using his self-described method of "assembly," augmenting this process with devices to synchronize the music with the picture. Examination of archival sources shows how the score reflects the acknowledged influence of Igor Stravinsky, the needs of the film medium, and the plot of The Red Pony specifically. Despite Copland's modern style characteristics, the music functions much like a conventional Hollywood film score.

Woven Music

Woven Music

Date: May 2003
Creator: Jackson, Melanie S.
Description: When I am weaving I listen to music and notice that my hands and feet fall into a rhythm. This connection reminds me of playing the piano. I took a closer look at weaving drafts; the movement of the threading setup reminded me of the notes on musical scores. This relationship inspired me to see what textures I could achieve by actually weaving the musical notes. The focus of my study is the exploration of the relationships between weaving and music utilizing elements and principles found in both, such as: color, texture, form, repetition, rhythm, and time. Both music and color produce emotional responses and will be taken into consideration within the weavings.

Writing proficiency among graduate students in higher education programs.

Writing proficiency among graduate students in higher education programs.

Date: May 2003
Creator: Singleton-Jackson, Jill A.
Description: This study explored the extent to which graduate students enrolled in Higher Education courses were proficient at writing. While writing proficiency has been extensively studied in elementary students, high school students, and undergraduates, little attention has been paid to formally evaluating graduate student proficiency. Despite the relatively new idea of assessing graduate student writing, it is a concern for graduate faculty and a valid area for study. This study was based on a sample of graduate students enrolled in at least one course in Higher Education at public institutions of higher education in the United States. A total sample size of 97 students was obtained. Two instruments were administered to the participants: A General Information and Writing Experience Questionnaire (G-WEQ) and the SAT II: Writing Test, Part B. The G-WEQ was designed to capture demographic information about the participants, as well as allow participants to provide a self-assessment of writing and describe the writing experiences they are currently encountering in graduate school. To assess writing proficiency for the participants, the SAT II: Writing Test, Part B was used. The purpose of the test is to "measure [test takers'] ability to...recognize faults in usage and structure, and to use language with ...

Analysis and expression of the cotton gene for the D-12 fatty acid desaturases 2-4 (FAD2-4)

Analysis and expression of the cotton gene for the D-12 fatty acid desaturases 2-4 (FAD2-4)

Date: August 2003
Creator: Park, Stacy J.
Description: A genomic clone containing a 16.9-kb segment of cotton DNA was found to encompass a D-12 fatty acid desaturases (FAD2-4) gene. The FAD2-4 gene has a single, large intron of 2,780 bp in its 5'-untranslated region, just 12 bp upstream from the ATG initiation codon of the FAD2-4 opening reading frame. A number of prospective promoter elements, including several light-responsive sequences, occur in the 5'-flanking region. The coding region of the gene is 1155 bp with no introns, and would encode a FAD2-4 polypeptide of 384 amino acids. The putative protein had four membrane-spanning helices, hallmarks of an integral membrane protein, and would probably be located in the endoplasmic reticulum. The FAD2-4 gene is indeed a functional gene, since yeast cells transformed with a plasmid containing the coding region of the gene synthesize an appreciable amount of linoleic acid (18:2), not normally made in wild-type yeast cells. The FAD2-4 gene has many structural similarities to the cotton FAD2-3 gene that was also analyzed in this laboratory.

An Analysis of Joe Lovano's Tenor Saxophone Improvisation on "Misterioso" by Thelonius Monk: An Exercise in Multi-Dimensional Thematicism

An Analysis of Joe Lovano's Tenor Saxophone Improvisation on "Misterioso" by Thelonius Monk: An Exercise in Multi-Dimensional Thematicism

Date: August 2003
Creator: Dahlke, Andrew Richard
Description: The dissertation focuses on Joe Lovano's utilization of thematic material in relation to "Misterioso" by Thelonius Monk. Thematicism is defined more broadly in this study to include reference to the form, phrase structure, and harmony of "Misterioso". Methodological models provided by Gary Potter, Henry Martin, and Paul Hindemith serve as points of departure for this study which focuses on four areas: 1) phrasing, 2) step progression, 3) motives and formulas, and 4) harmonic implications. Thematic relationships are discovered through the analysis of the transcription of Lovano's improvisation; the four levels of the analysis work together and also independent of one another to produce a kind of thematic counterpoint. This study also examines how Lovano creates an effective solo. The study will be of benefit to students, professional musicians, pedagogues, theorists, musicologists, and jazz aficionados.

Applications of remote sensing and GIS to modeling fire for vegetative restoration in Northern Arizona

Applications of remote sensing and GIS to modeling fire for vegetative restoration in Northern Arizona

Date: August 2003
Creator: Hardison, Tanya
Description: An accurate fire model is a useful tool in predicting the behavior of a prescribed fire. Simulation of fire requires an extensive amount of data and can be accomplished best using GIS applications. This paper demonstrates integrative procedures of using of ArcGIS™, ERDAS Imagine™, GPS, and FARSITE© to predict prescribed fire behavior on the Kaibab-Paiute Reservation. ArcGIS was used to create a database incorporating all variables into a common spatial reference system and format for the FARSITE model. ArcGIS Spatial Analyst was then used to select optimal burn sites for simulation. Our predictions will be implemented in future interagency efforts towards vegetative restoration on the reservation.
