Production, Characterization And Possible Applications Of Monoclonal Antibodies Generated Against Toluene Diisocyanate-Conjugated Proteins, Tinashe Blessing Ruwona

Dissertations and Theses

Diisocyanates are very reactive low molecular weight chemicals that are widely used in the manufacture of polyurethane products. Diisocyanate exposure is one of the most commonly reported causes of occupational asthma. Although diisocyanates have been identified as causative agents of respiratory diseases, the specific mechanisms by which these diseases occur remain largely unknown.

Tandem mass spectrometry was used to unambiguously identify the binding site of isocyanates within four model peptides (Leu-enkephalin (Leu-enk, YGGFL), Angiotensin I (DRVYIHPFHL), Substance P-amide (RPKPQQFFGLM-NH₂), and Fibronectin-adhesion promoting peptide (FAPP, WQPPRARI)). In each case, isocyanates were observed to react to the N-terminus of the …

Investing And Vesting International Students' Expressive Resources In Social Capital At Portland State University, Mami Kikuchi

Dissertations and Theses

The study expands the conceptual and methodological precepts of social capital by examining how international students receive social capital from their friends and how students provide social capital to their friends in a North American university setting. The author examines the degree of emotional support that the participants provide ("Investing" social capital) and the support they receive from their friends ("Vesting" social capital), and the relationships between the two social capital variables. In addition, the study examines the influence of demographics and social interaction on social capital, and the influence of social capital on satisfaction. The study suggests that vesting …

Visions And Voices: An Arts-Based Qualitative Study Using Photovoice To Understand The Needs And Aspirations Of Diverse Women Working In The Sex Industry, Moshoula Capous Desyllas

Dissertations and Theses

The ways in which sex workers have been studied and represented historically, socio-politically and academically do not take into account their voices, subjective experiences and participation in the process. Women working in the sex industry are seldom heard and their needs are consistently defined and represented by others. This contributes to the stereotyping and stigmatization of sex workers, while academic research is consistently being done on sex workers instead of with them. This study uses the arts-based research method of photovoice with individuals working in the sex industry in Portland, Oregon to understand their needs and aspirations through their own …

Archaeological Evidence For Resilience Of Pacific Northwest Salmon Populations And The Socioecological System Over The Last ~7,500 Years, Sarah K. Campbell, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Archaeological data on the long history of interaction between indigenous people and salmon have rarely been applied to conservation management. When joined with ethnohistoric records, archaeology provides an alternative conceptual view of the potential for sustainable harvests and can suggest possible social mechanisms for managing human behavior. Review of the ~7,500-year-long fish bone record from two subregions of the Pacific Northwest shows remarkable stability in salmon use. As major changes in the ecological and social system occurred over this lengthy period, persistence in the fishery is not due simply to a lack of perturbation, but rather indicates resilience in the …

The Population Of Sap And Tsap Isomers In Cyclen-Based Lanthanide(Iii) Chelates Is Substantially Affected By Solvent, Kyle J. Miller, Ali A. Saherwala, Benjamin C. Webber, Yunkou Wu, A. Dean Sherry, Mark Woods

Chemistry Faculty Publications and Presentations

The square antiprism/twisted square antiprism ratio in LnDOTA-tetraamide chelates is a critical parameter in governing water-exchange kinetics and ultimately the utility of a chelate as a PARACEST MRI contrast agent. In LnDOTA-tetraamide chelates with tertiary amides, this ratio and the rate of interconversion between these two structural isomers are found to be dramatically dependent upon the solvent and possibly other local environmental factors.

Desegregation And Multiculturalism In The Portland Public Schools, Ethan Johnson, Felicia Williams

Black Studies Faculty Publications and Presentations

Helen Marie Casey’s booklet Portland’s Compromise: the Colored School, 1867–1872 recounts the story of William Brown, an African-American resident of Portland, Oregon, and his role in the first and only case of official segregation of African-American children in Portland Public Schools (PPS) in 1867. After unsuccessfully trying to enroll his children in one of Portland’s only two public elementary schools, Brown appealed to the school board, including directors Josiah Failing, W.S. Ladd, and E.D. Shattuck. Again, his children were denied access. The board of directors explained their resistance to integrated schools by saying: “If we admit them [African-American children], then …

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 …

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 …

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 …

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 …

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

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 …

Negotiating Meaning With Educational Practice: Alignment Of Preservice Teachers' Mission, Identity, And Beliefs With The Practice Of Collaborative Action Research, Jan Marie Carpenter

Dissertations and Theses

The case study examined how three preservice teachers within a Master of Arts in Teaching program at a small, private university negotiated meaning around an educational practice--collaborative action research. Preservice teachers must negotiate multiple, and often competing, internal and external discourses as they sort out what educational practices, policies, organizational structures to accept or reject as presented in the teacher education program. This negotiation is a dynamic, contextual, unique meaning-making process that extends, redirects, dismisses, reinterprets, modifies, or confirms prior beliefs (Wenger, 1998).

Korthagen's (2004) model for facilitating understanding and reflection was used to explore the process of negotiating meaning. …

"Everybody Goes Down": Metaphors, Stories, And Simulations In Conversations, L. David Ritchie

Communication Faculty Publications and Presentations

Recent work has shown that many problematic aspects of metaphor use and comprehension can be resolved through an account that includes both relevance and perceptual simulation. It has also been shown that metaphors often imply stories, and that stories are often metaphorical. Previous research on narratives has focused primarily on stories that appear either in formal literature or in structured interviews; this essay focuses on stories that occur as an integral part of conversation. It extends recent work on metaphor comprehension to show how use and comprehension of stories in natural, informal conversations can be usefully analyzed in terms of …

Democratic Triumph, Scholarly Pessimism, Bruce Gilley

Political Science Faculty Publications and Presentations

This article discusses how the democratic form of government has gone from an oddity to the most common form of government in the world. The written works on democracy in the past twenty years have dealt primarily with the writers' growing sense of insecurity, the belief that history runs in cycles, and the belief that democracy will run its course and the world will find itself returned to an authoritarian existence. Samuel P. Huntington expressed his pessimism with democracy in his book "The Third Wave." Huntington believes that only countries with a substantial Western influence will be able to sustain …

Institutional Grey Literature In The University Environment, Gretta E. Siegel

Library Faculty and Staff Publications and Presentations

Historically, attention to grey literature in the academic library was focused on external collections – documents produced by government agencies or research centers. Little, if any, systematic attention was paid to the grey literature that was produced on university campuses. The advent of the Web, while bringing more interest to grey literature in general did not change this situation much. However, the trend toward the creation of institutional repositories has caused a considerable shift in interest. The formalization of collecting, processing, and integrating academic institutional grey literature should be critical to the mission of the University, regardless of format, and …

Manufactured Home Parks: Norcs Awaiting Discovery, Andrée Tremoulet

Urban Studies and Planning Faculty Publications and Presentations

This paper examines manufactured home parks as a type of naturally occurring retirement community and considers the potential for adding social service programs (NORC-SSP) to enable further aging in place. An analysis of six focus group interviews with 48 residents found that the physical and social environment promoted a sense of safety and community, and that this housing option was an intentional lifestyle choice. Risks included the possibility of bad management and park closure. Manufactured home parks were found to offer an attractive option for exploring a NORC-SSP model that builds on residents' assets and community capacity.

Polyaniline Nanofibers As The Hole Transport Medium In An Inverse Dye-Sensitized Solar Cell, Ian Brock Hesselsweet

Dissertations and Theses

In order to become a viable alternative to silicon photovoltaics, dye-sensitized solar cells must overcome several issues primarily resulting from their use of a liquid electrolyte. Much research has gone into correcting these shortcomings by replacing the liquid electrolyte with solid-state hole-transport media. Using these solid-state materials brings new difficulties, such as completely filling the pores in the TiO₂ nanostructure, and achieving good adhesion with the dye-coated TiO₂. A novel approach to addressing these difficulties is the inverse dye-sensitized solar cell design. In this method the devices are constructed in reverse order, with the solid-state hole-transport medium providing the nanostructure …
