A Study Of Dynamic Optimization Techniques: Lessons And Directions In Kernel Design, Calton Pu, Jonathan Walpole

Computer Science Faculty Publications and Presentations

The Synthesis kernel [21,22,23,27,28] showed that dynamic code generation, software feedback, and fine-grain modular kernel organization are useful implementation techniques for improving the performance of operating system kernels. In addition, and perhaps more importantly, we discovered that there are strong interactions between the techniques. Hence, a careful and systematic combination of the techniques can be very powerful even though each one by itself may have serious limitations. By identifying these interactions we illustrate the problems of applying each technique in isolation to existing kernels. We also highlight the important common under-pinnings of the Synthesis experience and present our ideas on …

When Will A Genetic Algorithm Outperform Hill-Climbing?, Melanie Mitchell, John H. Holland

Computer Science Faculty Publications and Presentations

In this paper we review some previously published experimental results in which a simple hillclimbing algorithm-Random Mutation Hill-Climbing (RMHC)-significantly outperforms a genetic algorithm on a simple "Royal Road" function. vVe present an analysis of RMHC followed by an analysis of an "idealized" genetic algorithm (IGA) that is in turn significantly faster than RMHC. We isolate the features of the IGA that allow for this speedup, and discuss how these features can be incorporated into a real GA and a fitness landscape, making the GA better approximate the IGA. We use these features to design a modified version of the previously …

Nuclear Magnetic Resonance Investigation Of The Interaction Of Heme Binding Proteins With Snivprotoporphyrin Ix And Heme: Structure And Conformational Changes Of Myoglobin And Hemopexin, Ruba Saba Deeb

Dissertations and Theses

Tin protoporphyrin IX (SnPP) is currently under investigation for the treatment of hyperbilirubinemia. The study of the complex between SnPP and equine myoglobin (EqMb) by ¹H and ¹¹⁹Sn nuclear magnetic resonance spectroscopy (NMR) can be viewed as a general model for SnPP interaction with hemoproteins. The complex formed from the equilibrium mixture of SnPP and EqMb, SnPP•EqMb, was found to have essentially the same porphyrin-binding pocket as EqMbCO and SwMbCO, including the same porphyrin orientation in the major form of the two species. ¹¹⁹Sn NMR spectroscopy was used to demonstrate that the proximal His(93)F8-metal coordination is likely to be intact …

A Case Study Of The Acceptance Of The Tacoma-Pierce County Needle Exchange Program By Three Diverse Groups: Law Enforcement Personnel, Health Department Officials, And Program Clients (I.E., Intravenous Drug Users), Lauren Sue Ibrahim

Dissertations and Theses

Legitimate and underground needle exchange programs, specifically targeted for intravenous drug users (IVDUs) (i.e., currently the second largest risk group in the AIDS epidemic), have emerged in various locales in a desperate attempt to change their drug use practices and behaviors associated with the transmission of HIV-1/AIDS. This study focuses on one such program, the Tacoma-Pierce County Needle Exchange Program, in which the pioneering efforts of a private individual are provided, the manifestations of public entrepreneurism are examined, and in which various attributes of program acceptance are identified and explored. An introductory and exploratory case study approach is the research …

Urbanization In A Peripheral Capitalist State: A Guyana Case Study, Wazir Ahmad Ishmael

Dissertations and Theses

This research proposes to examine the process of urbanization in Guyana, South America. In particular, the objectives of this research are threefold. The first is to identify, describe, and evaluate some of the historic and current causes of urban growth and urbanization which have taken place in a peripheral capitalist state that was under the plantation mode and that illustrates a legacy of "uneven development." The second objective is to attempt to assess planning responses, through attempts by the state to formulate policies to deal more effectively with urbanization. And the third objective is to contribute to a dialogue between …

Vision, Interpersonal Orientation And Personal Values In Elementary School Principals, Allan Leslie Weston

Dissertations and Theses

This study looked at possible relationships which exist between three personal characteristics variables believed to be associated with effective leadership in elementary schools. The three variables were (1) Principal Vision, (2) Principal Interpersonal Orientation and, (3) Principal Personal Values. The relationship between selected teacher, principal and school demographic variables and teacher's perceptions of their principal's vision was also explored.

Data were collected from 51 principals and 841 teachers in elementary schools from 10 school districts in the Portland, Salem and Vancouver metropolitan areas. Teachers were asked to score their perceptions of their principal's vision on the School Vision Inventory. The …

A Validation Study Of Components Necessary For The Professional Development Of School Business Officials, William Henry Dierdorff Iii

Dissertations and Theses

A key element of a profession is a formalized training program. School business officials in the United States and Canada face dynamic and complex issues without a standardized training program. This study surveyed a representative group to validate a curriculum model developed by a 1988 task force funded by the Danforth Foundation. Another objective was to increase awareness of the need for an effective training program for school business officials and the most appropriate sources to implement that. As indicated in the analysis, all components of the ASBO/Danforth model were considered important to the parties surveyed. There was no single …

Perceived Administrative Support For Teachers Of Urban At-Risk Students, Betsy Bennet-Costi

Dissertations and Theses

The purpose of this study was to investigate effective administrative support for successful teachers of urban at-risk students. The main difficulty in studying administrative support is that it comes in so many ways. Johnson’s (1990) theory of workplace variables and Butterworth's (1981) social exchange theory were the basis for this study. Failures of at-risk students threaten the well being of public schools and have become a generally recognized social problem of national priority. This study explores how principals act to influence the success of teachers as they work with at-risk students. It is grounded in the following four assumptions: 1. …

State Policy And Public Administration Impacts On An Emerging Industry: The Wine Industry In Oregon And Washington, Anthony Gene White

Dissertations and Theses

Oregon and Washington state administrative agencies’ impacts on economic development within the winery industry are examined. Policy cluster development appears to impact economic development programs differently in each state. The wine industry has flourished in both states since 1970, yet Oregon with 60% of Washington's population supports 10% more wineries. Oregon winery numbers continue to grow while Washington’s seem to have leveled out. From the literature and industry interviews, three variables were selected to be tested for their industry impacts:

1. domestic consumption (state population times wine industry per-capita consumption);
2. market domination (estimated from interviews and proportional market share); and
3. net …

An Implementation Analysis Of The Water Resources Development Act Of 1986, James Joseph Rich

Dissertations and Theses

Implementation research, an area once largely ignored in favor of policy design and impact assessment, now constitutes a significant portion of the policy analysis literature. One of the key issues addressed by the theory building portion of that literature is the necessity of precisely identifying implementation variables, conditions, or actions that measurably contribute to the success or failure of implementation efforts over a broad range of policies and programs, and to then suggest some order of significance. In order to test the validity of a variable set proposed by the literature, a multivariate implementation model was employed as the basis …

Solidification And Morphology Of Submarine Lavas: A Dependence On Extrusion Rate, Ross W. Griffiths, Jonathan H. Fink

Geology Faculty Publications and Presentations

The results of recent laboratory experiments with wax extruded beneath relatively cold water may be extrapolated to predict the surface morphology of submarine lavas as a function of the extrusion rate and melt vIscosity. The experiments with solidifying wax indicated that the surface morphology was controlled by a single parameter, the ratio of the time taken for the surface to solidify, and a time scale for lateral flow. For submarine basalts a solution of the cooling problem (which is dominated by conduction in the lava but convective heat transfer in the water) and estimates of lava viscosities place this parameter …

The Morphology Of Lava Flows In Planetary Environments: Predictions From Analog Experiments, Ross W. Griffiths, Jonathan H. Fink

Geology Faculty Publications and Presentations

The rates of surface cooling and lateral spreading are evaluated for lava flows on the surface of Earth, Venus, Mars, the Moon, and 10. Differences between the flow morphologies expected in these environments are then predicted under the assumption that the results of recent laboratory simulations oflavas using wax extruded beneath cold water (Fink and Griffiths, 1990) can be carried over. These experiments involved the spreading of viscous liquid under gravity in the presence of a solidifying surface crust and revealed a set of four distinct surface morphologies. Transitions from one morphology to the next occurred in a well-defined sequence …

Correction Of Chromatic Aberration With An Electron Mirror, Michael Stewart Mauck

Dissertations and Theses

The theoretical basis for using electron mirrors as correctors of chromatic aberration is presented and an experimental verification of correction of chromatic aberration is demonstrated. A hyperbolic electrostatic electron mirror operating in its converging range and at unity magnification was used as a corrector. A novel separating system with deflections taking place at image planes was developed to implement the mirror without impairing the resolution. Correction was demonstrated in an electron optical probe system. The chromatic aberration was measured by means of the shadows cast by a fine mesh placed near the final image. The experimental method and equipment are …

John F. Kennedy: A Political Biography On Education, David Eugene Armontrout

Dissertations and Theses

In what is historically a brief number of years, the life and times of John F. Kennedy have taken on legendary proportions. His presidency began with something less than a mandate from the American people, but he brought to the White House an inspiration and a style that offered great promises of things to come.

This study provides a political biography of John F. Kennedy and education. In addition, it investigates the records of past presidents and congresses, as well as the school aid lobby. This account also draws upon the vast body of historical, educational, and political material on …

Perceptions Of China And The Chinese People In The British Periodical And Newspaper Press, 1860-1900, William M. Stegemeyer

Dissertations and Theses

Few historians have examined the portrayals of China by British writers during the nineteenth century. Although Britain lead all other western powers in the penetration, exploration and exploitation of the Chinese Empire during the nineteenth century, British perceptions of China, particularly during the critical final decades of the century, have only been presented as small parts of larger comprehensive surveys of western images of China. Historians agree that as a result of Britain's active role in China, British writers were the leading transmitters of information about China to the West, especially after the formal 'opening' of China by treaty after …

A Technique For The Evaluation Of Double Excitation Of Atoms By Fast Protons And Antiprotons, Jack C. Straton, James H. Mcguire, Zheng Chen

Physics Faculty Publications and Presentations

A technique for evaluating cross sections for two-electron excitation in collisions of atoms with fast particles of charge ZP is presented. The atomic wave function is approximated by a sum of pair products of one-electron wave functions, with the coefficients chosen by diagonalizing the fully correlated twoelectron Hamiltonian. Thus spatial correlation is included in both the asymptotic and scattering regions by using these configuration-interaction (Cl) wave functions for initial, intermediate, and final states. Use of CI wave function also allows the first-order contributions to be expressed in closed, analytical form. Both the energy-conserving and energy-nonconserving parts of the second-order amplitude …

Democratic Ideology, The Frontier Ethos, Medical Practice And Hospital Culture: Pacific Northwest Health-Seekers, Community Health And The Sisters Of Providence, Vancouver, Wa 1856 - 1879, Susan T.L. Courtney

Dissertations and Theses

Most historians readily acknowledge the economic incentive that prompted many pioneers to migrate westward across the overland trail. Health motivations remain generally unexplored. Many Americans had settled the interior regions most suited to farming, especially the acreage around river valleys in the Mississippi drainage system. Unfortunately, health conditions were not favorable to human existence.

The dilemma of economic well-being versus health disaster motivated a number of Americans to seek better living conditions. Some chose overland migration to the Pacific Northwest. The situation in contemporary medical practice was a kaleidoscope of competing sects and contradictory convictions. The mainline profession of medicine, …

Hawthorne Boulevard: Commercial Gentrification And The Creation Of An Image, Rachel Ann Hardyman

Dissertations and Theses

Portland's Southeast Hawthorne Boulevard illustrates commercial gentrification in progress. Once a declining service district, "Hawthorne" is now one of the city's most popular shopping streets. Tracing and classifying businesses, using address listings from city directories, gives an accurate picture of changes since 1980. Three parallel trends can be distinguished in the makeup of the business mix: a shift from services to retailing; a move towards a regional, rather than a neighborhood, market area; and a cultural upgrading associated with the influx of increasingly expensive stores. Classification also aids in the definition of a tipping point at which revitalization became gentrification. …
