A Beer Party And Watermelon: The Archaeology Of Community And Resistance At Ccc Camp Zigzag, Company 928, Zigzag, Oregon, 1933-1942, Janna Beth Tuck

Dissertations and Theses

In March 1933, the administration of United States President Franklin D. Roosevelt initiated a national relief program aimed at alleviating the disastrous effects ofthe Great Depression. The Civilian Conservation Corp (CCC) began as one of these programs designed to employ young men from all over the country and put them "back to work". The CCC provided these young men with training, a monthly stipend, and basic supplies such as food, clothing, and accommodations. After 1942, CCC camps were closed and many of these sites were abandoned or destroyed, leaving little historical documentation as to the experiences ofthe people involved. This …

An Empirical Assessment Of The Can Spam Act, Alex Conrad Kigerl

Dissertations and Theses

In January 2004, the United States Congress passed and put into effect the Controlling the Assault of Non-Solicited Pornography and Marketing Act (CAN SPAM). The Act was set forth to regulate bulk commercial email (spam) and set the limits for what was acceptable. Various sources have since investigated and speculated on the efficacy of the CAN SPAM Act, few of which report a desirable outcome for users of electronic mail. Despite the apparent consensus of anti-spam firms and the community of email users that the Act was less than effective, there is little to no research on the efficacy of …

Expressive Motion Synthesis For Robot Actors In Robot Theatre, Mathias I. Sunardi

Dissertations and Theses

Lately, personal and entertainment robotics are becoming more and more common. In this thesis, the application of entertainment robots in the context of a Robot Theatre is studied. Specifically, the thesis focuses on the synthesis of expressive movements or animations for the robot performers (Robot Actors). The novel paradigm emerged from computer animation is to represent the motion data as a set of signals. Thus, preprogrammed motion data can be quickly modified using common signal processing techniques such as multiresolution filtering and spectral analysis. However, manual adjustments of the filtering and spectral methods parameters, and good artistic skills are still …

Extraction Of Small Boat Harmonic Signatures From Passive Sonar, George Lloyd Ogden

Dissertations and Theses

This thesis investigates the detection and classification of small boats using a passive sonar system. Noise radiated from a small boats consists of broadband noise and harmonically related tones that correspond to parameters in the boats engine and propeller. A novel signal processing method for detection and discrimination of noise radiated from small boats has been developed. There are two main components to the algorithm. The first component detects the presence of small boats by the harmonic tonals radiated from the boat propeller and engine. The second component was designed to extract the a signature from passive sonar data. The …

Addressing Automated Adversaries Of Network Applications, Edward Leo Kaiser

Dissertations and Theses

The Internet supports a perpetually evolving patchwork of network services and applications. Popular applications include the World Wide Web, online commerce, online banking, email, instant messaging, multimedia streaming, and online video games. Practically all networked applications have a common objective: to directly or indirectly process requests generated by humans. Some users employ automation to establish an unfair advantage over non-automated users. The perceived and substantive damages that automated, adversarial users inflict on an application degrade its enjoyment and usability by legitimate users, and result in reputation and revenue loss for the application's service provider. This dissertation examines three challenges critical …

The Foundation To Collaborate: Understanding The Role Of Participant Interests, Tia S. Henderson

Dissertations and Theses

Collaborative processes are widely used to harness resources for addressing community problems. Despite their positive potential, collaborative projects can fragment. Sources of fragmentation include participant misperception of facts, difficulties in defining the problem, and misunderstandings among stakeholders. Disruptions from these elements may impede a group's progress in fostering and implementing agreements. Theoretical and empirical research from conflict resolution has shown that discussing participant interests and the use of facilitation techniques can help negotiators engage in innovative problem solving. Interests are participants' underlying needs, concerns, and desires that shape how individuals perceive issues and the stances they take. Less attention has …

The corrosion behavior of electrochemically deposited copper thin films in deareated and non-dearated cleaning solution containing hydrofluoric acid (HF) has been investigated. Potentiodynamic polarization experiments were carried out to determine active, active-passive, passive, and transpassive regions. Corrosion rates were calculated from tafel slopes. ICP-MS and potentiodynamic methods yielded …

The Impact Of Humanitarian Photography On The Generation Of Sympathy And On Donation Behavior, Marta Barberini

Dissertations and Theses

This paper presents findings of an exploratory study to evaluate the impact of humanitarian photography on the generation of sympathy and donation behavior. Considering the large amount of money spent each year by charity organizations on marketing strategies, it seems crucial to shed light on the persuasive impact of images in this context. The overarching purpose of this study was to discern what impact, if any, a number of features in a photograph have on sympathetic reactions. Specifically the author examined facial expressions (sad vs. happy), eye contact vs. no eye contact and total number of subjects portrayed. Findings supported …

Use Of Media Technologies By Native American Teens And Young Adults: Evaluating Their Utility For Designing Culturally-Appropriate Sexual Health Interventions Targeting Native Youth In The Pacific Northwest, Stephanie Nicole Craig Rushing

Dissertations and Theses

American Indian and Alaska Native (AI/AN) youth are disproportionally burdened by high rates of sexually transmitted infections and teen pregnancy, heightening their need for sexual health interventions that are aligned to their unique culture and social context. Media technologies, including the Internet, cell phones, and video games, offer new avenues for reaching adolescents on a wide range of sensitive health topics. While several studies have informed the development of technology-based interventions targeting mainstream youth, no such data have been reported for AI/AN youth. To fill this gap, I: a) quantified media technology use in a select group of AI/AN teens …

The majority of research on CAS has been conducted with children who are otherwise typically developing. The purpose of this study was to determine whether and to what extent children with autism are being diagnosed with or suspected to have CAS as well as what assessment and treatment methods are currently being used with these children. Method: A nationwide survey of speech-language pathologists (SLPs) working with children ages 0-6 …

The Micropivot : An Integrated Particle Image Velocimeter And Optical Tweezers Instrument For Microscale Investigations, Nathalie Neve De Mevergnies

Dissertations and Theses

This dissertation describes the development of a device capable of suspending a microscale object in a controlled flow. The uPIVOT is a system integrating two laser-based techniques: micron particle image velocimetry (uPIV) and optical tweezers (OT). The OT allows the suspension and manipulation of micron-sized objects such as microspheres or biological cells. uPIV provides imaging of the suspended object and velocity measurements from which fluid induced stresses can be determined. Using this device, we measured fluid velocities around an optically suspended polystyrene microsphere (an experimental first) and studied the interaction between two particles suspended in a uniform flow. The results …

Parental Differential Treatment (Pdt) Of Siblings: Examining The Impact And Malleability Of Differential Warmth And Hostility On Children's Adjustment, Brianne H. Kothari

Dissertations and Theses

Parental differential treatment (PDT), the within-family differences in parenting experienced by siblings (Rivers & Stoneman, 2008), has been linked to detrimental adjustment outcomes for children (e.g., Conger & Conger, 1994). The primary goal of this research was to more closely examine how differential treatment in two domains of parent-child relations-displays of warmth and hostility- were associated with child outcomes. A secondary data analysis was conducted on a Randomized Controlled Trial (RCT) of a parent training intervention. Participants in this sample were high risk children and families, and they were randomly assigned to one of three groups: an intensive parent training …

The Effects Of Ageism Climates And Core Self-Evaluations On Nurses' Turnover Intentions, Organizational Commitment, And Work Engagement, David Michael Cadiz

Dissertations and Theses

It is estimated that by 2018, workers age 55 or older will compose nearly a quarter of the labor force (Tossi, 2009). The aging workforce is dramatically affecting the nursing workforce. Indeed, the nursing workforce is expected to face staffing shortages of epidemic proportions because of the impending retirement of nurses who are Baby Boomers (Buerhaus, et al., 2006). Moreover, the nursing shortage is exacerbated by younger nurses' greater willingness to turn over (Aiken et al., 2001). Consequently, investigating how the workplace context affects retention of nurses is important. The present study sought to address the nursing shortage concern through …

Hombres En Accion (Men In Action): A Community Defined Domestic Violence Intervention With Mexican, Immigrant, Men, Rosemary Carmela Celaya-Alston

Dissertations and Theses

Studies suggest that knowledge, attitudes, and beliefs about domestic violence influence the behaviors of Mexican men. However, few interventions have targeted men in efforts to provide domestic violence awareness and health education to a relevant at-risk community that is also challenged by low literacy. Mexican immigrant men, particularly those less acculturated to the dominant U.S. culture, are significantly less likely to access services and more likely to remain isolated and removed from their communities and, more importantly, from their families. The purpose of this study was to explore and examine how cultural beliefs and behaviors influence the potential of domestic …

A Library And Its Community: Exploring Perceptions Of Collaboration, Phoebe Vincenza Daurio

Dissertations and Theses

This study explores perceptions of interorganizational collaboration through an investigation of the opinions and actions of a public library and three community-based organizations. Interorganizational collaboration is often viewed as an effective strategy for accomplishing objectives that would not otherwise be possible with a single organization. Particularly for complex societal issues such as adult literacy, researchers and practitioners believe collaboration between organizations is necessary in order to achieve desired outcomes. Public libraries are engaging in collaborations also to extend their reach, establish the library’s relevance, increase community involvement, and advocate for their position as a community asset.

This thesis is a …

Design Space Analysis And A Novel Routing Agorithm For Unstructured Networks-On-Chip, Neha Parashar

Dissertations and Theses

Traditionally, on-chip network communication was achieved with shared medium networks where devices shared the transmission medium with only one device driving the network at a time. To avoid performance losses, it required a fast bus arbitration logic. However, a single shared bus has serious limitations with the heterogeneous and multi-core communication requirements of today's chip designs. Point-to-point or direct networks solved some of the scalability issues, but the use of routers and of rather complex algorithms to connect nodes during each cycle caused new bottlenecks. As technology scales, the on-chip physical interconnect presents an increasingly limiting factor for performance and …

Leo Strauss And The Problem Of Sein: The Search For A "Universal Structure Common To All Historical Worlds", Jennifer Renee Stanford

Dissertations and Theses

Leo Strauss resurrected a life-approach of the ancient Greeks and reformulated it as an alternative to the existentialism of his age that grew out of a radicalized historicism. He attempted to resuscitate the tenability of a universal grounded in nature (nature understood in a comprehensive experiential sense not delimited to the physical, sensibly-perceived world alone) that was historically malleable. Through reengagement with Plato and Socrates and by addressing the basic premises built into the thought of Friedrich Nietzsche and Martin Heidegger, Strauss resurrected poetry (art, or the mythos) that Enlightenment thinkers had discarded, and displayed its reasonableness on a par …

Regional Integration In East Asia, Amaleia E. Kolovos

Dissertations and Theses

This paper will seek to use both Europe and East Asia as illustrations in order to better comprehend the driving forces behind integration as well as why some regions are further integrated than others. The purpose of this research is to achieve a better understanding of what causes regional integration in hopes of developing a more inclusive theory. More specifically, it aims to …

Spousal Crossover Effects Of Job Demands On Health, Rachel Jane Daniels

Dissertations and Theses

The primary goal of this dissertation was to examine the crossover effects of an individual's job demands on the perceived health of the spouse. Using a sample of grocery store employees and their partners, crossover relationships were examined for 90 dyads using Structural Equation Modeling. Although the models had good fit, the proposed direct crossover relationships of job demands on health were not supported. Job demands of one partner did not significantly predict health outcomes in the other partner; although follow-up analyses found significant crossover of women's job satisfaction on men's mental health scores. An additional crossover relationship was supported …

Portland's Independent Music Scene: The Formation Of Community Identities And Alternative Urban Cultural Landscapes, Rebecca Elizabeth Ball

Dissertations and Theses

Portland has a rich, active, and fluid music culture which is constantly being (re)created and (re)defined by a loose network of local musicians who write, record, produce, promote, distribute, and perform their music locally (and sometimes regionally, nationally, and internationally) and local residents, or audiences, who engage in local musical practices. Independent ("indie") local music making in Portland, which is embedded in DIY (do it yourself) values, creates alternative cultural places and landscapes in the city and is one medium through which some people represent themselves in the community. These residents not only perform, consume, promote, and distribute local music, …

Design Of Regular Reversible Quantum Circuits, Dipal Shah

Dissertations and Theses

The computing power in terms of speed and capacity of today's digital computers has improved tremendously in the last decade. This improvement came mainly due to a revolution in manufacturing technology by developing the ability to manufacture smaller devices and by integrating more devices on a single die. Further development of the current technology will be restricted by physical limits since it won't be possible to shrink devices beyond a certain size. Eventually, classical electrical circuits will encounter the barrier of quantum mechanics. The laws of quantum mechanics can be used for building computing systems that work on the principles …

Identifying Best Quality Management Practices For Achieving Quality And Innovation Performance In The Forest Products Industry, Scott A. Leavengood

Dissertations and Theses

In many business sectors today, the focus on quality as a competitive tool is being replaced by a focus on innovation. Research exploring connections between quality management, innovation, and company performance suggests that quality is 'necessary but insufficient' in today's business environment. In short, the question facing managers, particularly those in small firms, is how to adapt their quality management practices to achieve innovation performance in addition to quality performance. To answer this question, West Coast U.S. forest products manufacturers were surveyed about quality management practices and performance with respect to both quality and innovation. Quality management practices were assessed …

Functional Separation Of Multimodular Type I Pks Polypeptides By Utilizing Matched Docking Domains From A Heterologous Pks System, John Kam Yan

Dissertations and Theses

Bacterial type I modular polyketide synthases (PKS) are large multifunctional enzyme systems responsible for the biosynthesis of complex polyketide natural products such as erythromycin, pikromycin, and borrelidin. Type I systems are comprised of a loading module which generally selects an appropriate acyl group starter unit, and multiple discrete extension modules, responsible for each single round of acyl group incorporation into the final polyketide core structure. These modules can exist naturally as either single discrete polypeptides, such as modules 5 and 6 from the pikromycin PKS (PikA3 and PikA4 respectively), or as multimodular polypeptides fused together by short intrapolypeptide linkers such …

American Scientists, Americanist Archaeology: The Committee On Radioactive Carbon 14, Keith David Baich

Dissertations and Theses

Willard Libby's development of carbon-14 dating at the University of Chicago immediately following World War II provided an unprecedented opportunity for the collaboration of archaeologists with a physical chemist. Libby's need for archaeological samples to test the dating process (1947-1951) meant that he relied upon the Committee on Radioactive Carbon 14, formed by the American Anthropological Association, for datable materials, as well as for assistance in all other archaeologically related aspects of the testing phase. The committee, under the leadership of archaeologist Frederick Johnson, served the mandated function of providing assistance to Libby, but simultaneously endeavored to utilize the new …

Coal To Oil In China: Scientific Development Or Crossing The River By Feeling The Stones?, Joseph John Narus

Dissertations and Theses

Since the start of the 21st century, energy security concerns and rising international energy costs have led China to pursue the development of a coal to oil industry, whereby converting a portion of the nation's abundant coal reserves into gasoline, diesel, or jet fuel, China might be able to increase its domestic oil production and generate profits. But a large-scale coal to oil industry exerts added pressure on China's domestic coal reserves and water resources, and generates significant greenhouse gas emissions. The tension between the potential benefits of coal to oil development and its associated negative externalities present a challenge …

Multi-Criteria Trucking Freeway Performance Measures For Congested Corridors, Nicole Marie Wheeler

Dissertations and Theses

This research focuses on the development of multi-criteria tools for measuring and analyzing the impacts of recurring and non-recurring congestion on freight corridors in the Portland Metropolitan Area. Unlike previous studies, this work employs several distinct data sources to analyze the impacts of congestion on Interstate 5 (I-5) in the Portland Metropolitan Area: global positioning system (GPS) data from commercial trucks and Oregon DOT corridor travel-time loop data and incident data. A new methodology and algorithms are developed to combine these data sources and to estimate the impacts of recurrent and non-recurrent congestion on freight movements' reliability and delays, costs, …

Library Characterization And Static Timing Analysis Of Single-Track Circuits In Gasp, Swetha Mettala Gilla

Dissertations and Theses

Library characterization and 'Static Timing Analysis' (STA) are widely used in the design of modern CMOS integrated circuits to confirm that critical timing constraints are met. While many commercial tools are available to do timing validation using library characterization and static timing analysis, their operation depends on calculations relative to a global synchronous clock. This thesis applies timing validation to circuits from which the global synchronous clock is absent, making application of commercial tools difficult. Previous work at the University of Southern California (USC) showed how to overcome the incompatibility of commercial STA tools for asynchronous circuits. This thesis shows …

Predictors Of Family-Supportive Supervisor Behaviors: Supervisor Job Stress And Work-Family Climate, Brittany E. Sale

Dissertations and Theses

Research indicates that supportive supervision, particularly work-family specific supervision, is key to reducing employees' work-family conflict (Allen, 2001; Eby et al., 2005; Thomas & Ganster, 1995). However, little research has examined the factors that contribute to supervisors' willingness or ability to provide this support. This study examined how supervisor job stress and perceptions of work-family climate influenced employee ratings of Family-Supportive Supervisor Behaviors (FSSB) using previously-collected data from a mid-western grocery chain. It was hypothesized that supervisor job stressors would impact FSSB, supervisor perception of work-family climate would impact FSSB, and the interaction of stressors and climate would impact FSSB. …

Achieving Congruence: Building A Case For Implementing A District-Wide Interim Benchmark Assessment That Is Aligned With A Balanced Literacy Framework, Theodore Feller

Dissertations and Theses

For generations--and certainly for the last 30 years--proponents of traditional and progressive philosophies have argued over how best to educate our children. Although this debate is often carried out in the political and academic spheres, the difficulties created by not being able to resolve the differences between the two belief systems become blatantly clear in the pedagogy of early literacy. On the one hand, traditionalists argue for a direct and explicit instructional methodology, and on the other hand, progressives advocate for Whole Language or Balanced Literacy instruction. The classroom often becomes a battlefield as advocates of these opposing schooling paradigms …

A Comparison Of Single Word Identification, Connected Speech Samples, And Imitated Sentence Tasks For Assessment Of Children With A Ssd, Emily Katherine Snyder

Dissertations and Theses

Speech-language pathologists are constantly trying to use the most efficient and effective assessments to obtain information about the phonetic inventory, speech sound errors, and phonological error patterns of children who are suspected of having a speech sound disorder. These assessments may involve a standardized measure of single words and/or sentences and a non standardized measure, such as a spontaneous speech sample. While research has shown both of these types of assessments to give clinicians information about a child's speech production abilities, the use of delayed imitation tasks, either words or sentences, has not been a widely studied topic and has …
