Unrelated Business Enterprise And Unfair Business Competition Issues Facing Nonprofit Organizations, Larry Glen Scruggs

Dissertations and Theses

Unrelated business enterprises have been an appropriate way for nonprofit organizations to generate income since the first income tax was enacted into law. The Internal Revenue Act of 1950 clarified this opportunity and enacted the Unrelated Business Income Tax to ensure that fair competition existed between nonprofits and for profit organizations. Nonprofit organizations conducting unrelated business enterprises are faced with a dilemma: it is legal for them to conduct such enterprises but if they do so they face potential litigation from for profit business for unfair competition and/or potential loss of tax-exempt status for operating outside of their exempt function. …

Geometrical Modeling Of Material Aging, Alexander Chudnovsky, Serge Preston

Mathematics and Statistics Faculty Publications and Presentations

Material aging is understood as changes of material properties with time. The aging is usually observed as an improvement of some properties and a deterioration of others. For example an increase of rigidity and strength and reduction in toughness with time are commonly observed in engineering materials. In an attempt to model aging phenomena on a continuum (macroscopical) level one faces three major tasks. The first is to identify an adequate age parameter that represents, on a macroscopic scale, the micro and sub microscopical features, underlying the aging phenomena such as nucleation, growth and coalescence of microdefects, physico-chemical transformations etc. …

Violent Youth Gangs In Portland: A Study Of The City's Response, Debra Lynn Lindberg

Dissertations and Theses

Youth gangs infiltrated Portland's illegal drug trade in the early 1980s. By the mid-1980s, entire neighborhoods in some parts of the city were affected. Residents expressed fear that their children would be drawn into gangs. Violence between rival gangs was frightening. Citizens, law enforcement and social services personnel organized to defend themselves and adjust programs to manage the problem. City officials denied a problem existed until a gang style shooting death forced recognition. The shooting death was catalytic in that it launched an effort to respond with a continuum of services. The House of Umoja was one of the services. …

Impact Of The Medical Library Assistance Act Of 1965 On Health Sciences Libraries In The Pacific Northwest: An Interorganizational Approach, Leonoor Swets Ingraham

Dissertations and Theses

Since the 1960's, the number of publications has increased at a phenomenal rate, and the introduction of the computer has resulted in greatly expanded technological advances in information processing and information access. The information delivery component of health sciences libraries has been transformed; and concomitantly, their interorganizational relations have been altered. This research investigates the impact of a federally mandated information program. The Medical Library Assistance Act was passed in 1965 to support the escalating information needs of health professionals. Also, a computerized access system for biomedical literature was introduced by the National Library of Medicine. This study focuses on …

Oregon's Carry Concealed Weapon Laws: A Historical Review Of The Right To Personal Protection, Richard Meek Bash

Dissertations and Theses

This thesis reviews many of the historical, constitutional and legal factors behind today's gun control policy and how they relate to the laws governing the carrying of concealed firearms within the state of Oregon. Many legal cases are explored for their impact on the carriage of concealed weapons. A thorough examination was made of the Oregon legislative history behind HB 3470, sponsored by then-House Speaker Vera Katz, which was enacted in July 1989, was effective January 1, 1990, and became the kernel of the snowball passage of CCW (carry concealed weapon) laws within the United States. Statistical tests were conducted …

Mechanisms Of Pentachlorophenol Induced Charge Transport In Lipid Membranes, William Charles Brown

Dissertations and Theses

Pentachlorophenol (PCP) is one of the prominent environmental pollutant that has penetrated into food chain and is present in humans. Health concerns have been raised since daily intake of PCP by the US population is estimated to be 16-19 µg. PCP facilitates dissipation of electrochemical potential gradients of hydrogen ions across energy transducing membranes, which are the energy sources for the conversion of adenosine diphosphate into adenosine triphosphate. Closely linked to these dissipative effects is the development of electrical conductivity in lipid membranes, induced by the presence of PCP. Three modes of PCP - induced membrane electrical conductivity were theoretically …

Generalized Beam Matrices. Ii. Mode Selection In Lasers And Periodic Misaligned Complex Optical Systems, Lee W. Casperson, Anthony A. Tovar

Electrical and Computer Engineering Faculty Publications and Presentations

A generalized beam matrix method is used to investigate the mode structure of astigmatic misaligned optical systems with loss or gain. In these optical systems the usual real-argument polynomial-Gaussian beams are not eigenfunctions, and off-axis complex-argument polynomial beams must be used. New beam transformations for these complex-argument modes are reported. Stability criteria are developed, and mode selection in laser resonators that contain tilted, displaced, or curved complex optical elements is discussed.

Adaptive Methods For Distributed Video Presentation, Crispin Cowan, Shanwei Cen, Jonathan Walpole, Carlton Pu

Computer Science Faculty Publications and Presentations

This paper describes problems and solutions for delivering real-time, multi-media presentations across the Internet. A key characteristic of presentations of continuous media datatypes, such as digital video and audio, is their need for predictable real-time data delivery. For example, an NTSC quality video presentation requires video frames to be displayed every 1/30th of a second. Variations in this display rate can be observable as stalls or glitches in the video stream and reduce the quality of the presentation [6]. Delivering such presentations across the Internet is difficult because highly variable band- width and latency make it difficult to predict the …

Device And Physical Data Independence For Multimedia Presentations, Richard Staehli, Jonathan Walpole, David Maier

Computer Science Faculty Publications and Presentations

Multimedia computing promises access to any type of visual or aural medium on the desktop. But in this networked future, will every type of media be accessible from every terminal device? Current multimedia standards do not allow content that is authored for high-bandwidth workstations to scale down for low-bandwidth applications. The problem is that application requests are commonly interpreted as requests for the highest possible quality and resource overloads are handled by ad hoc methods. We can begin to solve this problem by specifying Quality of Service (QOS) requirements based on functionality rather than on content encoding and device capabilities.

Customizable Operating Systems, Jonathan Walpole, Crispin Cowan, Andrew P. Black, Jon Inouye, Calton Pu, Shanwei Cen

Computer Science Faculty Publications and Presentations

A customizable operating system is one that can adapt to improve its functionality or performance. The need for customizable and application-specific operating systems has been recognized for many years, but they have yet to appear in the commercial market. This paper explores the notion of operating system customizability and examines the limits of existing approaches. The paper begins by surveying system structuring approaches for the safe and efficient execution of customizable operating systems. Then it discusses the burden that existing approaches impose on application software, and explores techniques for reducing this burden. Finally, support for customizability in the Synthetix project …

Quality Of Service Specification For Multimedia Presentations, Richard Staehli, Jonathan Walpole, David Maier

Computer Science Faculty Publications and Presentations

The bandwidth limitations of multimedia systems force tradeoffs between presentation data fidelity and real-time performance. For example, digital video is commonly encoded with lossy compression to reduce bandwidth and frames may be skipped during playback to maintain synchronization. These tradeoffs depend on device performance and physical data representations that are hidden by a database system. If a multimedia database is to support digital video and other continuous media data types, we argue that the database should provide a Quality of Service (QOS) interface to allow application control of presentation timing and information loss tradeoffs.

This paper proposes a data model …

Monte Carlo Simulations Of The Extinction Rate Of Densely Packed Spheres With Clustered And Nonclustered Geometries, Lisa M. Zurk, L. Tsang, K. H. Ding, Dale P. Winebrenner

Electrical and Computer Engineering Faculty Publications and Presentations

Scattering and absorption coefficients are presented from Monte Carlo simulations of electromagnetic wave propagation in a volume of densely packed, random dielectric, absorptive spheres. The particles are modeled both with and without a surface adhesion that causes them to form clustered groups. Results for scatterer densities greater than a few percent by volume differ significantly from those obtained under the independentscattering assumption. The extinction rates agree well with analytic dense-medium theory. Results also show that, on account of local fields experienced by the particles, the system absorption is different from that predicted with an assumption of independent absorption. Scattering is …

Dialogue And Critical Thinking In Personal Action, Amanda Elizabeth Feller

Dissertations and Theses

A common criticism of U.S. citizens today, whether as voters or students or workers, is that they are "lazy and apathetic". It is important to explore the validity of this criticism. This thesis begins with the premise that there are two prerequisites for citizenship in a democracy: (1) that citizens be willing to participate and (2) that citizens are able to participate.

The purpose of this research is to examine a particular set of perspectives regarding social conditions which consistently impact the two aforementioned prerequisites. This examination addresses social conditions that undermine a person's ability to participate meaningfully and it …

Generalized Beam Matrices: Gaussian Beam Propagation In Misaligned Complex Optical Systems, Anthony A. Tovar, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

A novel 3 × 3 transfer-matrix method is developed to propagate off-axis Gaussian beams in astigmatic optical systems that may include tilted, displaced, or curved optical elements. Unlike in a previous generalized ray matrix formalism, optical elements that possess gain or loss such as Gaussian apertures, complex lenslike media, and amplifiers are included; and a new beam transformation is found. In addition, a novel exponential variable-reflectivity mirror, which displaces a Gaussian beam without changing its spot size, and a complex prismlike medium are introduced.

Planning In The Portland Region: Lessons And Legacy, Ethan Seltzer

Institute of Metropolitan Studies Publications

This paper examines the path that Portland and its region has taken from being a place showing little evidence of "modern city planning practice" to its current and apparently much more attractive state. First, a cautionary note. We have probably been both more and less successful than it sounds. Stories of municipal accomplishment tend to take on greater dimension the further you get from home. Take this one with a grain of salt. From the outside looking in, condition what you see with the following: First, there are no silver bullets or supremely right answers. It takes a mix of …
