Conflict Emergence And Escalation In Interactive International Dyads, David Todd Kinsella, Bruce M. Russett

Political Science Faculty Publications and Presentations

We examine whether the conditions affecting initial expressions of hostility are similar to those affecting militarized disputes. Analyzing dyadic interactions during the years 1951–1992, we estimate a model to take into account selection effects and check it against another allowing conjunctive causation. Both provide close approximations to theoretical models of the conflict process and yield similar results. We confirm Kant’s belief that all states are subject to the realist conditions of interstate competition that makes disputes likely, but that liberal influences, if present, can constrain the escalation of such disputes to war. Several influences on the conflict process have nonmonotonic …

The Role Of Trust, Leader-Member Exchange, And Organizational Justice In Employee Attitudes And Behaviors: A Laboratory And Field Investigation, Rudolph Joseph Sanchez

Dissertations and Theses

The study of interpersonal relationships continues to be a major focus of theory and research in a wide array of disciplines. The present research examined one of the most prevalent and significant interpersonal relationships in the workplace context—the dyadic relationship between a supervisor and a subordinate. This research examined the relationships between trust, quality of the leader-member exchange relationship (LMX; a measure of the quality of the dyadic relationship), perceived organizational justice, and several employee attitudes and behaviors that are important to individual workers and the organizations in which they work.

Data were collected in both laboratory and field settings. …

Recurring Beams In Hollow Metal Waveguides: Paraxial Approximation, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

For optical and near-optical applications in electromagnetics, the directed propagation of waves in free space and in lenslike media is often in the Cartesian form of Gaussian or more general Hermite-sinusoidal-Gaussian beams. It has been shown that recurring (rather than continuing) forms of such beams are possible in the paraxial approximation for certain hollow metal waveguides, in which multiple reflections from the waveguide walls may occur. Limitations on this recurrence behavior implicit in use of the paraxial approximation are considered here, and estimates are obtained for the maximum propagation distance before the onset of significant distortion of the recurring beams.

A Lessons Learned Repository For Computer Forensics, Warren Harrison, George Heuston, Mark Morrissey, David Aucsmith, Sarah Mocas, Steve Russelle

Computer Science Faculty Publications and Presentations

The Law Enforcement community possesses a large, but informal, community memory with respect to digital forensics. Large, because the experiences of every forensics technician and investigator contribute to the whole. Informal because there is seldom an explicit mechanism for disseminating this wisdom except “over the water cooler”. As a consequence, the same problems and mistakes continue to resurface and the same solutions are re-invented. In order to better exploit this informal collection of wisdom, the key points of each experience can be placed into a Repository for later dissemination. We describe a web-based Lessons Learned Repository (LLR) that facilitates contribution …

Tri-Met's Experience With Automatic Passenger Counter And Automatic Vehicle Location Systems, James G. Strathman

Center for Urban Studies Publications and Reports

The Tri-County Metropolitan Transportation District of Oregon (Tri-Met) is one of about 30 metropolitan transit agencies that have deployed both automatic vehicle location (AVL) and automatic passenger counter (APC) systems (Casey, 1999). These technologies are important components of the agency’s new automated bus dispatching system (BDS). The AVL and APC systems at Tri-Met recover comprehensive operations and passenger activity data at the bus stop level that is archived for later analysis. The agency has gained a reputation as an industry leader in the areas of data archiving and the application of archived data to performance monitoring and analysis.

Gay Bars, Vice, And Reform In Portland, 1948-1965, Beka Smith

Dissertations and Theses

The city of Portland adopted different policies toward gay bars between 1948 and 1965. Portland's conservative mayors, generally uninterested in changing the city or promoting growth, ignored gay bars. Reform mayors instigated campaigns against gay bars to gain public, political, and business support for their broader economic and social goals. They were able to use crackdowns on gay bars as popular components of their reform initiatives because Portland, in comparison to other cities, professed conservatism and morality and had little economic or cultural incentive to tolerate gay bars. Blaming Portland's vice on outsiders, reform mayors argued that their actions protected …

The Transformation Of Civic Institutions And Practices In Portland, Oregon, 1960-1999, Steven Reed Johnson

Dissertations and Theses

In this dissertation I examine how the organizational framework for civic life in Portland, Oregon, changed between 1960 and 1999 and identify several key aspects of the transformation.

The most basic change has been in the type of organizations involved in civic issues. In 1960 civic life in Portland was dominated by traditional civic organizations: fraternal and benevolent organizations, women's clubs, voluntary and charitable organizations, ethnic cultural groups, and direct social service organizations. By 1999 traditional civic organizations were displaced by advocacy oriented organizations: identity interest groups, neighborhood associations, citizen interest organizations, and social service organizations that advocated for causes. …

Ballot Ballet: The Metroscape’S Delicate Dance With Direct Democracy, David Santen

Institute of Metropolitan Studies Publications

Referred to as the “fourth branch” of the Oregon political system, the ballot initiative process has defined Oregon politics as much if not more than any of the traditional legislative, executive, and judicial branches of government. After a century on the books, it continues to grow in stature and presence, evidenced from the increased bulk of both the Voters' Pamphlet and the Oregon Constitution itself. It tackles the entire spectrum of issues, affecting residents of Clackamas, Columbia, Multnomah, Washington, and Yamhill Counties, and often spilling over into Clark County, Washington, and beyond. Land use and property rights, structure of the …

The Final Frontier: Using Space Under 2040, John Provo

Metroscape

Later this year the Metro Council will face a decision about expansion of the urban growth boundary (UGB). Reaching a verdict on that question will require negotiating the conflicts between the long term regional vision described in Metro's 2040 Plan, short-term economic fluctuations, and specific local concerns. Looking at possible tradeoffs and choices facing the region, panelists at a recent Metroscape™ forum on these topics were asked to discuss the connections among implementation, design, and market challenges involved in planning for the integration of open space with denser development in regional centers.

What follows are excerpts from a panel discussion …

Gscope: A Visualization Tool For Time-Sensitive Software, Ashvin Goel, Jonathan Walpole

Computer Science Faculty Publications and Presentations

This paper describes gscope, a visualization tool for time-sensitive applications. Gscope provides an oscilloscope-like interface that can be integrated with applications. It focuses on software visualization and is thus designed to handle various types of signal waveforms, periodic or event-driven, in single or multithreaded environments as well as local or distributed applications. Gscope helps in visually verifying system correctness and modifying system parameters and thus can complement standard debugging techniques and be used to build compelling software demos. Initial experiments with using gscope show that the library has low overhead.

Implementing Infopipes: The Sip/Xip Experiment, Calton Pu, Galen Swint, Charles Consel, Younggyun Koh, Ling Liu, Koichi Moriyama, Jonathan Walpole, Wenchang Yan

Computer Science Faculty Publications and Presentations

We describe an implementation of the Infopipe abstraction for information flow applications. We have implemented software tools that translate the SIP/XIP variant of Infopipe specification into executable code. These tools are evaluated through the rewriting of two realistic applications using Infopipes: a multimedia streaming program and a web source combination application. Measurements show that Infopipe-generated code has the same execution overhead as the manually written original version. Source code of Infopipe version is reduced by 36% to 85% compared to the original.

Discrimination And Nepotism Within Police Specialty Units, Robert Norvell Hollins Iii

Dissertations and Theses

A career as a police officer has served as a legitimate avenue for many Black Americans to elevate themselves from numerous low paying less prestigious jobs, to a more respectable better paying secured occupation that has a higher social economic status. The general perception related to the civil service position of a police officer, suggests that it is an occupation which should offer an environment free from discrimination and nepotism, thereby allowing fair treatment and equal access for advancement to all individuals employed within the police organization.

The concept of a police organization that offers fair treatment and equal access …

Provisioning On-Line Games: A Traffic Analysis Of A Busy Counter-Strike Server, Wu-Chang Feng, Francis Chang, Wu-Chi Feng, Jonathan Walpole

Computer Science Faculty Publications and Presentations

This paper describes the results of a 500 million packet trace of a popular on-line, multi-player, game server. The results show that the traffic behavior of this heavily loaded game server is highly predictable and can be attributed to the fact that current game designs target the saturation of the narrowest, last-mile link. Specifically, in order to maximize the interactivity of the game itself and to provide relatively uniform experiences between players playing over different network speeds, on-line games typically fix their usage requirements in such a way as to saturate the network link of their lowest speed players. While …

Supporting Low-Latency Tcp-Based Media Streams, Ashvin Goel, Charles Krasic, Kang Li, Jonathan Walpole

Computer Science Faculty Publications and Presentations

The dominance of the TCP protocol on the Internet and its success in maintaining Internet stability has led to several TCP-based stored media-streaming approaches. The success of these approaches raises the question whether TCP can be used for low-latency streaming. Low latency streaming allows responsive control operations for media streaming and can make interactive applications feasible. We examined adapting the TCP send buffer size based on TCP's congestion window to reduce application perceived network latency. Our results show that this simple idea significantly improves the number of packets that can be delivered within 200 ms and 500 ms thresholds.

Automatic Passenger Counter Evaluation: Implications For National Transit Database Reporting, Thomas J. Kimpel, James G. Strathman, David Griffin, Steve Callas, Rick Gerhart

Center for Urban Studies Publications and Reports

This paper presents findings from a study assessing the accuracy and precision of automatic passenger counter (APC) technology at Tri-County Metropolitan Transportation District of Oregon (Tri-Met). Video surveillance cameras, rather than ride checkers, were used to establish reference values for determining APC accuracy and precision. Analysis of data collection, processing and reporting methods at Tri-Met indicates that APC data, along with a properly designed sampling plan, can be used for internal monthly ridership reporting and annual National Transit Database (NTD) reporting. Presently, NTD sampling plans require that bus trips be randomly selected prior to manual data collection efforts. The sampling …

The Crisis Of Scientific Information Dissemination In North America, Gretta E. Siegel

I used to be a scientist, but I am not one now. I am a librarian, and my remarks are based on 17 years of observation and experience as a librarian. However, libraries exist in …

Infopipes: An Abstraction For Multimedia Streaming, Andrew P. Black, Huang Jie, Rainer Koster, Jonathan Walpole, Calton Pu

Computer Science Faculty Publications and Presentations

To simplify the task of building distributed streaming applications, we propose a new abstraction for information flow – Infopipes. Infopipes make information flow primary, not an auxiliary mechanism that is hidden away. Systems are built by connecting predefined component Infopipes such as sources, sinks, buffers, filters, broadcasting pipes, and multiplexing pipes. The goal of Infopipes is not to hide communication, like an RPC system, but to reify it: to represent communication explicitly as objects that the program can interrogate and manipulate. Moreover, these objects represent communication in application-level terms, not in terms of network or process implementation.
