The Transnational Networks Of Cultural Commodities: Peruvian Food In San Francisco, Kelsey Ann Brain

Dissertations and Theses

In a setting of increased movement, communication, and flows across space, commodity chain networks bring valued cultural commodities to transnational communities. This research examines the networks bringing foreign cuisine ingredients to Peruvian transnational communities in San Francisco, California. It seeks to answer three inter-related questions: 1) What are the origins and transportation networks bringing Peruvian food items to San Francisco; 2) Who controls and benefits from the movement of this food and resulting capital; and 3) How do networks vary for different classes of end consumers?

Chefs of ten Peruvian restaurants and ten Peruvian migrants in the San Francisco area …

The Effect Of Athletic Participation On Academic Achievement For High School Seniors In Eastern Tennessee, David Andrew Gorman

Doctoral Dissertations and Projects

This causal-comparative study with a narrative component investigated the effect athletic participation on the academic achievement of senior student-athletes and non-athletes who attended three public high schools in Eastern Tennessee. The impetus for the study was the conflicting research as it relates to the impact athletics participation had on academic success at the college and high school levels. Through student athlete and non-athlete comparisons of ACT scores and GPAs, the researcher found athletic participation did not affect academic achievement for high school seniors who graduated in 2009 from the three target high schools when compared to non-athletes. However, statistically significant …

Which “Body” Is A Temple (1 Corinthians 6:19)? Paul Beyond The Individual/Communal Divide, Nijay Gupta

Faculty Publications - Portland Seminary

Pauline scholarship has always been interested in the “theology” of the Apostle, and questions of his understanding of God, Christ, salvation, the church, and ethics are as passionately pursued now as in any prior generation. An important methodological point that has been widely accepted among scholars, though, is that such attempts at extracting theological bits from Paul must take sufficient account of the ancient context of his writing and the “contingency” of his literary engagements, that is, “the specificity of the occasion to which it was addressed.” One major manifestation of this concern for understanding Paul in his original setting …

The Death Of Suspicion, Fabio Arcila Jr.

Scholarly Works

This article argues that neither the presumptive warrant requirement nor the presumptive suspicion requirement are correct. Though representative of the common law, they do not reflect the totality of our historic experience, which includes civil search practices. More importantly, modern developments - such as urban life and technological advancements, the rise of the regulatory state, and security concerns post-9/11 - have sufficiently changed circumstances so that these rules are not just unworkable now, they are demonstrably wrong. Worst of all, adhering to them has prevented us from formulating a more coherent Fourth Amendment jurisprudence. A new paradigm confronts us, in …

It's The Principal Of The Thing: Guiding A Rural School Has Its Own Trials, Susan Wilson, Tim France

Metroscape

The difficulties of K-12 education have become familiar to citizens of the metroscape, but they are usually viewed through the lens of urban and suburban schools, with their problems of multi-ethnic populations, crowded classrooms, strained budgets, and the like. Metroscape® was curious about the struggles and triumphs of the schools in the rural areas of the region, so we sent our interviewer, Susan Wilson, a Portland freelance writer, to Willamina to talk to a small town education leader in hopes of glimpsing the realities of schooling kids in that often overlooked setting.

A small-town principal is a versatile member of …

Extensible Scheduling In A Haskell-Based Operating System, Kenneth William Graunke

Dissertations and Theses

This thesis presents Lighthouse, an experimental branch of the Haskell-based House operating system which integrates Li et al.'s Lightweight Concurrency framework. First and foremost, it improves House's viability as a "real operating system" by providing a new extensible scheduler framework which makes it easy to experiment with different scheduling policies. In particular, Lighthouse extends Concurrent Haskell with thread priority and implements a priority-based scheduler which significantly improves system responsiveness when compared with GHC's normal round-robin scheduler. Even while doing this, it improves on House's claim of being "written in Haskell" by moving a whole subsystem out of the complex C-based …

Community Development For A White City: Race Making, Improvementism, And The Cincinnati Race Riots And Anti-Abolition Riots Of 1829, 1836, And 1841, Silas Niobeh Crowfoot

Dissertations and Theses

This project is an historical ethnography and a cultural history of the anti-black race riots and anti-abolition riots in Cincinnati, Ohio, in 1829, 1836, and 1841. It is also a case history in an urban and commercial/early industrial context of the idea that violent social practices such as riots, as well as law and the customary practices of everyday living, are deployed as race making technologies, actually constructing racial categories. By extending this constructivist concept to the conversion of space to place through the human ascription of meaning, this study also examines racial violence as a strategy for place making …

Fundamental Studies In Selective Wet Etching And Corrosion Processes For High-Performance Semiconductor Devices, Nabil George Mistkawi

Dissertations and Theses

As multistep, multilayer processing in semiconductor industry becomes more complex, the role of cleaning solutions and etching chemistries are becoming important in enhancing yield and in reducing defects. This thesis demonstrates successful formulations that exhibit copper and tungsten compatibility, and are capable of Inter Layer Dielectric (ILD) cleaning and selective Ti etching. 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 …

American Belly Dance And The Invention Of The New Exotic: Orientalism, Feminism, And Popular Culture, Jennifer Lynn Haynes-Clark

Dissertations and Theses

Belly dance classes have become increasingly popular in recent decades in the United States. Many of the predominantly white, middle-class American women who belly dance proclaim that it is a source of feminist identity and empowerment that brings deeper meaning to their lives. American practitioners of this art form commonly explain that it originated from ritual-based dances of ancient Middle Eastern cultures and regard their participation as a link in a continuous lineage of female dancers. In contrast to the stigmatization and marginalization of public dance performers in the Middle East today, the favorable meaning that American dancers attribute to …

Changes In Oregon Batterer Intervention Program Characteristics In Relation To State Standards, Ashley Lynn Boal

Dissertations and Theses

The social problem of intimate partner violence affects approximately one-half to two million individuals each year in the United States (Catalano, 2007; Tjaden & Thoennes, 2000). Commonly the criminal justice system mandates completion of a group-based intervention intended to prevent violent behavior (Dalton, 2007). These groups are typically referred to as a batterer intervention program (BIP). Despite the popularity of this intervention approach, research findings examining the efficacy of these programs remain inconsistent (Babcock, Green & Robie, 2004). Nonetheless, 45 U.S. states including the District of Columbia, have implemented standards that aim to proscribe and regulate elements of program functioning. …

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 …

Medical Image Segmentation Using A Genetic Algorithm, Payel Ghosh

Dissertations and Theses

Advances in medical imaging technology have led to the acquisition of large number of images in different modalities. On some of these images the boundaries of key organs need to be accurately identified for treatment planning and diagnosis. This is typically performed manually by a physician who uses prior knowledge of organ shapes and locations to demarcate the boundaries of organs. Such manual segmentation is subjective, time consuming and prone to inconsistency. Automating this task has been found to be very challenging due to poor tissue contrast and ill-defined organ/tissue boundaries. This dissertation presents a genetic algorithm for combining representations …

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 …

Investigating Freeway Speed-Flow Relationships For Traffic Assignment Applications, Meead Saberi Kalaee

Dissertations and Theses

Developments in high resolution traffic sensors over the past decades are providing a wealth of empirical speed-flow data. Travel demand models use speed-flow relationships to assign traffic flows to network links. However, speed-flow relationships have not been revalidated against new detailed traffic sensor data. Therefore, it is necessary to revisit speed-flow relationships based on actual measured conditions on network links rather than assuming constant speed-flow relationships over entire highway network systems. Speed-flow relationships have been particularly difficult to calibrate and estimate when traffic volumes approach capacity, i.e. when the v/c ratio approaches one. This thesis empirically evaluates the speed-flow relationships …

Northeast Asia And The Avoidance Of A Nuclear Arms Race, Samuel Fogleman

Dissertations and Theses

Since the end of the Sino-Vietnamese War in 1979, Northeast Asia and its comprising countries have avoided international conflict as well as any regional set has done over the past few decades. The absence of nuclear weapons among Japan, South Korea, and Taiwan, in particular, is striking, given their technological and scientific capabilities. Though each of those countries has come close at times to developing their own nuclear weapons, one factor or another contributed to the failure of those upstart programs. The United States has played a significant role in all of them. Still, other factors remain. The purpose of …

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 …

Development Of A Portable Cavity Ring-Down Spectroscopic Technique For Measuring Stable Isotopes In Atmospheric Methane, Gregory A. Bostrom

Dissertations and Theses

Trace gases can have a significant impact on the Earth's climate, and the analysis of changes in these gases and an understanding of how much of these changes are a result of human activity is important for understanding global climate change. Methane (CH₄) is the second only to CO₂ in radiative forcing over the last 200 years, and its concentration in the atmosphere has more than doubled since 1750. Sources and sinks of CH₄ have characteristic isotopic effects, which shift the relative concentration of the methane isotopologues. Spectroscopic techniques for of analysis the isotopic composition of …

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 …

Fabrication, Field Emission Properties And Theoretical Simulation Of Triode-Type Carbon Nanotube Emitter Arrays, Jianfeng Wu

Dissertations and Theses

Carbon nanotubes exhibit excellent field emission properties and will likely be prime candidates as electron sources in future vacuum electronic applications. Recent research has focused on enhancing field emission from traditional diode-type emitters by adding a gate electrode between the anode and the cathode. Since the gate to cathode (emitter) distance in this triode-type structure is small relative to the anode to cathode distance, this structure allows relatively small gate voltages to significantly enhance or dampen field emission. The key challenge for this research is: synthesizing vertically aligned carbon nanotube field emitters inside arrays of triode-type devices. The most common …

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 …

Hydrologic Data Assimilation: State Estimation And Model Calibration, Caleb Matthew Dechant

Dissertations and Theses

This thesis is a combination of two separate studies which examine hydrologic data assimilation techniques: 1) to determine the applicability of assimilation of remotely sensed data in operational models and 2) to compare the effectiveness of assimilation and other calibration techniques. The first study examines the ability of Data Assimilation of remotely sensed microwave radiance data to improve snow water equivalent prediction, and ultimately operational streamflow forecasts. Operational streamflow forecasts in the National Weather Service River Forecast Center are produced with a coupled SNOW17 (snow model) and SACramento Soil Moisture Accounting (SAC-SMA) model. A comparison of two assimilation techniques, the …

Activism And Identity: How Korea's Independence Movement Shaped The Korean Immigrant Experience In America, 1905-1945, Sara Elizabeth Deede

Dissertations and Theses

The Korean Independence Movement was a four decades long endeavor from 1905 to 1945 by Koreans to liberate Korea from Japanese colonization. Korean immigrants in America played a vital role in the movement. They contributed money, organized patriotic activities in their communities to raise awareness and issued appeals for support to the U.S. government. Throughout the years, and from generation to generation, Korean immigrants remained loyal to Korea's cause for liberation. This study discusses how this intense patriotic involvement to their homeland affected Koreans immigrants' experiences in America, namely, how such intense overseas nationalism shaped their Americanization process. Korean immigrants …

Beyond The "Stalled Revolution": Stay-At-Home Fathers, Gender Identity And The Division Of Household Labor, Aundrea Janae Snitker

Dissertations and Theses

The purpose of this thesis is to explore how stay-at-home fathers view their role as the primary caregiver, and how they encounter opposing masculinity issues. This is explored through discussion about daily life, the decision to stay home, and household labor, a particularly interesting reflection of gender roles and equality. The two research questions used to explore this included: How do stay-at-home fathers understand their masculinity and social role? How does talk about the negotiation of household labor in stay-at-home father/career mother families illustrate masculinity issues? Through an analysis of interviews of eight present or past stay-at-home fathers, I capture …

Bilingual Spanish-English Speaking 4-Year-Old-Children: English Normative Data And Correlations With Parent Reports, Brooke Leann Powers

Dissertations and Theses

Many bilingual Spanish-English preschool aged children are impacted by speech sound disorders; and research has shown that bilingual speech sound systems develop differently than monolinguals'. Research has also shown that, for monolingual English and Spanish speakers, parent reports can be a valid tool for identification and single-word assessments can effectively diagnose speech disorder, yet little, if any, normative data or information about the validity of parent reports as an identification tool exists for bilingual Spanish-English speakers. The purpose of the present study was to create bilingual speech normative data for English single-word assessment scores for percent consonants correct (PCC), percent …
