D. A. Kolb’s Theory of Experiential Learning: Implications for the Development of Music Theory Instructional Material

Description: This research project evaluates the effectiveness of specific music theory instructional strategies in terms of D. A. Kolb’s theory of experiential learning and Kolb’s typology of individual learning style. The project provides an original methodology for the adaptation of music theory instructional material to the individual learning style types described in Kolb’s typology. The study compares the relative effectiveness of two music theory instructional sequences, one of which is adapted for all of the learning style modalities described in Kolb’s typology, and the other adapted for only a limited number of Kolb’s learning style types. In order to compare the potential “learning outcomes” produced by these instructional sequences, a detailed study is proposed, in which computer based instruction (CBI) will deliver the instructional sequences to research participants and electronically record the participants’ responses. The current study demonstrates the effective aspects of the original methodology and suggests methods for the successful adaptation of music theory instructional material to individual student learning styles.

Accelerator Mass Spectrometry Measurements of Plutonium in Sediment and Seawater from the Marshall Islands

Description: During the summer 2000, I was given the opportunity to work for about three months as a technical trainee at Lawrence Livermore National Laboratory, or LLNL as I will refer to it hereafter. University of California runs this Department of Energy laboratory, which is located 70 km east of San Francisco, in the small city of Livermore. This master thesis in Radioecology is based on the work I did here. LLNL, as a second U.S.-facility for development of nuclear weapons, was built in Livermore in the beginning of the 1950's (Los Alamos in New Mexico was the other one). It has since then also become a 'science center' for a number of areas like magnetic and laser fusion energy, non-nuclear energy, biomedicine, and environmental science. The Laboratory's mission has changed over the years to meet new national needs. The following two statements were found on the homepage of LLNL (http://www.llnl.gov), at 2001-03-05, where also information about the laboratory and the scientific projects that takes place there, can be found. 'Our primary mission is to ensure that the nation's nuclear weapons remain safe, secure, and reliable and to prevent the spread and use of nuclear weapons worldwide'. 'Our goal is to apply the best science and technology to enhance the security and well-being of the nation and to make the world a safer place.' The Marshall Islands Dose Assessment and Radioecology group at the Health and Ecological Assessments division employed me, and I also worked to some extent with the Centre for Accelerator Mass Spectrometry (CAMS) group. The work I did at LLNL can be divided into two parts. In the first part Plutonium (Pu) measurements in sediments from the Rongelap atoll in Marshall Islands, using Accelerator Mass Spectrometry (AMS) were done. The method for measuring these kinds of samples is …

ADENOVIRUS INTERACTION WITH ITS CELLULAR RECEPTOR CAR.

Description: The mechanism of adenovirus attachment to the host cell plasma membrane has been revealed in detail by research over the past 10 years. It has long been known that receptor binding activity is associated with the viral fibers, trimeric spike proteins that protrude radially from the vertices of the icosahedral capsid (Philipson et al. 1968). In some adenovirus serotypes, fiber and other virus structural proteins are synthesized in excess and accumulate in the cell nucleus during late stages of infection. Fiber protein can be readily purified from lysates of cells infected with subgroup C viruses, for example Ad2 and Ad5 (Boulanger and Puvion 1973). Addition of purified fiber protein to virus suspensions during adsorption strongly inhibits infection, indicating that fiber and intact virus particles compete for binding sites on host cells (Philipson et al. 1968; Hautala et al. 1998). Cell binding studies using purified radiolabeled fiber demonstrated that fiber binds specifically and with high affinity to the cell plasma membrane, and that cell lines typically used for laboratory propagation of adenovirus have approximately 10{sup 4} high-affinity receptor sites per cell (Persson et al. 1985; Freimuth 1996). Similar numbers of high-affinity binding sites for radiolabeled intact virus particles also were observed (Seth et al. 1994).

ADVANCED DATA PROCESSING FOR VOLUMETRIC COMPUTED TOMOGRAPHY DATA

Description: Computed tomography (CT) has long been used by industry as a non-destructive evaluation technique for discovering flaws in parts before their use. Traditional linear array computed tomography systems acquired data at a rate that could be reconstructed simultaneously with data acquisition. With new area detectors, the data rate of acquisition has increased exponentially, and the reconstruction algorithm does not scale linearly with increased data. FlashCT DPS (Flat Panel Amorphous Silicon High Resolution Computed Tomography, Data Processing System) is a software package developed by M. Sheats, and A. Davis at LANL to meet the data processing demands of new flat panel array computed tomography. FlashCT--DPS combines several features unique to industrial computed tomography systems. It addresses traditional usability problems by providing an intuitive graphical user interface and powerful analysis tools. It includes the three major CT reconstruction algorithms: parallel backprojection, fan beam resorting, and Feldkamp cone beam. It also provides visualization tools for examination of data after processing. Finally, it is able to perform distributed data reconstruction with a near linear speed increase as a function of the number of processors used. Additionally, utility programs have been developed to support project editing and computing cluster management for the FlashCT system. FlashCT--DPS runs on a standard PC platform and operates well on a variety of processor and memory configurations.

Alexander Johnson's Ni' Concerto (1994) - Concerto no. 1 for Piano and Orchestra: a Discussion of Influences from Africa, Eastern and Western Europe

Description: In the new generation of artists emerging in South Africa, Alexander Johnson is considered the most prolific young composer of his day. In a recent review in the Pretoria News, Johnson has been praised by eminent critic Paul Boekkooi as a composer who has “an ear for the exotic and knows exactly how to bring it off....” He continued by noting that his music is “mentally engrossing, pleasurable to the senses and seems refreshingly free from dogmatic formulas." Johnson writes for musicians and the general public to equal satisfaction. His accessible compositions and catching use of melodic materials have made his writings very popular both in South Africa and abroad. During his residency in Belgrade in 1993-94, Johnson met Croatian pianist Dorian Leljak. Impressed with Johnson's compositional ideas and output, Leljak commissioned a work from Johnson for piano and orchestra. The result was the Niš Concerto, which Johnson completed in April 1994. The world premiere took place on June 23, 1994 with the Niš Philharmonic Orchestra conducted by Anatoli Nowiestski with Dorian Leljak as soloist. The Niš Concerto received its South African premiere in 1995 during a simultaneous celebration for “Europe Day” and the new democracy of the Republic of South Africa. The Delegation of the European Commission of South Africa sponsored the celebration, which took place in the Aula Auditorium on the campus of the University of Pretoria. The performers included the Artium Symphony Orchestra, conducted by Dutch-born Prof. Henk Temmingh and Johnson himself as piano soloist.

Amplitude Modulation of Atomic Wavefunctions - Final Technical Report

Description: This project developed a novel wave function modulation technique. Other modulation techniques use tailored laser pulses to directly excite a time-dependent, modulated wave function from a ground state. Our technique began with one electron already excited to a time independent eigenfunction. Then, by using excitations of a second valence electron, we modulated the other wave function. Our technique had the benefit that it was very efficient, and required low power lasers with no need for precise phase or amplitude control. On the other hand it had the difficulty of being a multi-step laser excitation with a maximum repetition rate of 10 Hz. Over the course of this project, we showed that the technique did work, and work efficiently. However, it was easy to generalize. Since the modulation depended on a difference between electron-electron interactions with the inner electron in a ground or excited state, the efficiency of the modulation was strongly state dependent. For example, we never showed any significant modulation in our tests of barium states, while our strontium measurements did show efficient modulation as long as the state to be modulated was in the 5snd group with n between 30 and 50. We completed some studies of the dependence of the amplitude modulation as we varied the time between the excitation and de-excitation pulses applied to the inner electron. The amplitude of the nearest neighbor states was well described by Multi-Channel Quantum Defect theory, but farther satellites were problematical. This may have simply reflected the low density of measurement points, since the amplitudes of the farther satellites oscillate more quickly with time. As we developed our technique, we showed that we could directly measure autoionization decay rates in the time domain, and that the net effect of a state belonging to a Rydberg series was that exponential decay …

ANALYSIS OF COMBINED FWCD AND NBI IN THE DIII-D TOKAMAK

Description: In recent experiments with combined fast wave current drive (FWCD) and deuterium neutral beam injection on the DIII-D tokamak [Luxon and Davis, Fusion Technol. 8, 441 (1985)], an enhanced fusion reactivity and fast ion energy content have been observed in the presence of FWCD, with a concomitant low FWCD efficiency [Petty et al., Radio Frequency Power in Plasmas (AIP, New York, 1997), p. 225]. In this paper, we investigate whether high-harmonic ion cyclotron damping could be responsible for the low FWCD efficiency in these experiments, since a number of high-harmonic hydrogen and deuterium cyclotron resonance layers existed in the plasma. The main analysis tool is the ICRF code PION [Eriksson, Hellsten and Willen, Nucl. Fusion 33, 1037 (1993)], modified to allow multiple frequencies simultaneously as was done in the DIII-D experiments. According to the PION modeling, high harmonic damping of fast wave power can give rise to enhanced fusion reactivity and fast ion energy content, which is consistent with the experimental observations.

An Analysis of Major American Riots: Issues in Riots and Riot Control

Description: By conducting sound research to understand the concepts surrounding rioting and efficient riot response tactics, professionals, especially whose main job is to ensure the tranquility in the society, will be better prepared to deal with all kinds of civil movements. The purpose of this study, consequently, is to meet the growing need for educational materials in this area and to provide riot response case studies, which demonstrate the numerous administrative challenges faced by law enforcement decision makers. In this study, seven major riots from throughout the United States are discussed including the Hay Market Riot of 1886, the Watts Riot of 1965, and Los Angeles Riots of 1992. Each riot case is studied in five different and independent stages: the setting and pre-disturbance situation, basic causes of the event, the disturbance situation, the response to the riot, and the aftermath of the incident. The study of all of these stages is intended to help police administrators acquire a general perspective on collective violence, and help them prevent future occurrences in their jurisdictions. In this thesis a special reference is given to the deficiencies of American riot policing and some recommendations were formed accordingly. Therefore, the study concludes with a list of general recommendations, which are crucially important for concerned officials to pay attention before, during, and after a riot.

An Analysis of the Effect of Environmental and Systems Complexity on Information Systems Failures

Description: Companies have invested large amounts of money on information systems development. Unfortunately, not all information systems developments are successful. Software project failure is frequent and lamentable. Surveys and statistical analysis results underscore the severity and scope of software project failure. Limited research relates software structure to information systems failures. Systematic study of failure provides insights into the causes of IS failure. More importantly, it contributes to better monitoring and control of projects and enhancing the likelihood of the success of management information systems. The underlining theories and literature that contribute to the construction of theoretical framework come from general systems theory, complexity theory, and failure studies. One hundred COBOL programs from a single company are used in the analysis. The program log clearly documents the date, time, and the reasons for changes to the programs. In this study the relationships among the variables of business requirements change, software complexity, program size and the error rate in each phase of software development life cycle are tested. Interpretations of the hypotheses testing are provided as well. The data shows that analysis error and design error occur more often than programming error. Measurement criteria need to be developed at each stage of the software development cycle, especially in the early stage. The quality and reliability of software can be improved continuously. The findings from this study suggest that it is imperative to develop an adaptive system that can cope with the changes to the business environment. Further, management needs to focus on processes that improve the quality of the system design stage.

Analytical Solutions for Sequentially Reactive Transport with Different Retardation Factors

Description: Integral transforms have been widely used for deriving analytical solutions for solute transport systems. Often, analytical solutions can only be written in closed form in frequency domains and numerical inverse-transforms have to be involved to obtain semi-analytical solutions in the time domain. For this reason, previously published closed form solutions are restricted either to a small number of species or to the same retardation assumption. In this paper, we applied the solution scheme proposed by Bauer et al. in the time domain. Using available analytical solutions of a single species transport with first-order decay without coupling with its parent species concentration as fundamental solutions, a daughter species concentration can be expressed as a linear function of those fundamental solutions. The implementation of the solution scheme is straight forward and exact analytical solutions are derived for one- and three-dimensional transport systems.

Anne Brontë's New Women: Agnes Grey and The Tenant of Wildfell Hall as Precursors of New Woman Fiction

Description: Anne Brontë's Agnes Grey and The Tenant of Wildfell Hall were published more than forty years before the appearance of the feminist type that the Victorians called the “New Woman;” yet, both novels contain characteristics of New Woman fiction. By considering how Brontë's novels foreshadow New Woman fiction, the reader of these novels can re-enact the “gentlest” Brontë as an influential feminist whose ideology informed the construction of the radical New Woman. Brontë, like the New Woman writers, incorporated autobiographical dilemmas into her fiction. By using her own experiences as a governess, Brontë constructs Agnes Grey's incongruent social status and a morally corrupt gentry and aristocracy through her depiction of not only Agnes's second employers, the Murrays, but also the morally debauched world that Helen enters upon her marriage to Arthur Huntingdon in The Tenant of Wildfell Hall. Moreover, Brontë incorporates her observations of Branwell's alcoholism and her own religious beliefs into The Tenant of Wildfell Hall. Although Brontë's novels contain autobiographical material, her heroines are fictional constructions that she uses to engage her readers with the woman question. Brontë accomplishes this engagement through her heroines' narrative re-enactments of fictional autobiographical dilemmas. Helen's diary and Agnes's diary-based narrative produce the pattern of development of the Bildungsroman and foreshadow the New Woman novelists' Kunstlerromans. Brontë's heroines anticipate the female artist as the protagonist of the New Woman Kunstlerromans. Agnes and Helen both invade the masculine domain of economic motive and are feminists who profess gender definitions that conflict with dominant Victorian ideology. Agnes questions her own femininity by internalizing the governess's status incongruence, and Helen's femininity is questioned by those around her. The paradoxical position of both heroines anticipates the debate about the nature and function of art in which the New Woman writers engaged. Through her reconciliation of the aesthetic …

Anti-Drug Media Campaign: Aspects of Advertising Contract Mismanaged by the Government; Contractor Improperly Charged Some Costs

Description: Testimony issued by the General Accounting Office with an abstract that begins "This testimony discusses the Office of National Drug Control Policy's (ONDCP) advertising contract for Phase III of the National Youth Anti-Drug Media Campaign. GAO found that the contractor, Ogilvy & Mather, improperly charged the government for some of its labor costs incurred under this contract. Ogivley & Mather submitted time sheets claiming hours that some employees said they did not work on the anti-drug media campaign. In addition, the company made little progress toward restructuring its accounting system to meet government requirements until nearly two years after the contract was awarded. The government poorly managed aspects of the award and administration of the contract. The Department of Health and Human Services (HHS) should not have awarded this cost-reimbursement contract without determining whether the contractor had an adequate cost accounting system. In addition, HHS should have reviewed the appropriateness of the large amount of money that the technical representative recommended be disallowed from the contractor's invoices, or arranged for an audit of the contract. The technical representative appropriately brought allegations of improper billing to the attention of ONDCP management, but ONDCP management did not take prompt action to investigate the allegations. Because the contract has not yet been audited, the appropriateness of the disallowed charges and Ogilvy's actual incurred costs under this contract remains unknown. This testimony summarized a June report (GAO-01-623)."
