Jobs And Gender: Does Sex Play A Role In The Region's Recession?, Mary C. King

Institute of Metropolitan Studies Publications

Unemployment rates in Oregon have been among the highest in the nation. In a real role reversal, unemployment in the seven counties of the Portland metropolitan area have hovered less than a percentage point below the state level, defying the usual rule that unemployment hits the rural counties far harder than the more diversified economies of the urban areas. Are we experiencing a “he-cession” here in the metroscape? Is the economic downturn hitting men hardest, leaving women relatively unscathed? Has stimulus spending disproportionately benefited men? Does it even make sense to think about an economic downturn having a gendered impact, …

Photovoice As Authentic Civic Engagement: Lessons Learned In One Immigrant Community, Meg Merrick, Angie Mejia

Institute of Metropolitan Studies Publications

It is widely acknowledged that equitable and sustainable public policy can only be achieved when it is informed by the concerns, hopes, and experiences of those who are affected. Public agencies wishing to engage recent immigrants can find this to be challenging, however. Effective public participation and civic engagement can be difficult when community members cannot speak English and/or come from very different cultural and political environments. The Chronic Disease Prevention Program (CDPP) of the Multnomah County Health Department and Metro, two public agencies serving the Portland, Oregon region, have actively sought to learn from the experiences of immigrant community …

Review Of Three Recent Randomized Trials Of School-Based Mentoring: Making Sense Of Mixed Findings, Marc E. Wheeler, Thomas E. Keller, David L. Dubois

School of Social Work Faculty Publications and Presentations

Between 2007 and 2009, reports were released on the results of three separate large-scale random assignment studies of the effectiveness of school-based mentoring programs for youth. The studies evaluated programs implemented by Big Brothers Big Sisters of America (BBBSA) affiliates (Herrera et al., 2007), Communities in Schools of San Antonio, Texas (Karcher, 2008), and grantees of the U.S. Department of Education's Student Mentoring Program (Bernstein et al., 2009). Differences in the findings and conclusions of the studies have led to varying responses by those in practice and policy roles. The results of the BBBSA trial led the organization to undertake …

School of Social Work Faculty Publications and Presentations

This narrative describes the author's journey away from a stance of innocence, toward one of humility in her engagement with pedagogy for the privileged. With deep attention to her identity, the contentious dimensions of this pedagogy have compelled her towards a much more troubled relationship with this practice. The following narrative profiles key contributions of pedagogy for the privileged, and articulates the contentions embedded within. It concludes with three essential ingredients to moderate her privilege: practicing from a stance of humility and "not knowing, " advancing research into the practice outcomes of such courses, and accountability structures where communities hold …

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 …

Modeling Terahertz Diffuse Scattering From Granular Media Using Radiative Transfer Theory, Kyung Moon Nam

Dissertations and Theses

Terahertz (THz) spectroscopy can potentially be used to probe and characterize inhomogeneous materials, however spectroscopic identification of such materials from spectral features of diffuse returns is a relatively underdeveloped area of study. In this thesis, diffuse THz scattering from granular media is modeled by applying radiative transfer (RT) theory for the first time in THz sensing. Both classical RT theory and dense media radiative transfer (DMRT) theory based on the quasi-crystalline approximation (QCA) are used to calculate diffuse scattered intensity. The numerical solutions of the vector radiative transfer equations (VRTE) were coded and calculated in MATLAB. The diffuse scattered field …

A Logic Formulation For The Qca Cell Arrangement Problem, Marc Stewart Orr

Dissertations and Theses

Some people believe that IC densities are approaching the fundamental limits inherent to semiconductor technologies. One alternative to semiconductors is Quantum-dot Cellular Automata (QCA); QCA is a nanotechnology that offers the potential to build denser IC's that switch at higher frequencies and run on lower power. QCA's most basic building block, the QCA cell, is inherently binary; digital circuits are implemented by arranging these QCA cells in pre-defined configurations on a two dimensional plane. This paper proposes a logic formulation that describes arranging QCA cells on a two dimensional plane; it is presented as a set of rules that can …

The Military Genogram: A Solution-Focused Approach For Resiliency Building In Service Members And Their Families, Eugenia Weiss, Jose Coll, Jennifer Gerbauer, Kate Smiley, Ed Carillo

School of Social Work Faculty Publications and Presentations

In recent decades, it has become evident among mental health practitioners that the military is a unique culture that is comprised of distinct ethics, core values, codes of conduct, and strict hierarchical roles. In light of the war in Afghanistan and the war in Iraq, veterans and their families are seeking mental health services due to a variety of psychosocial issues; however, mental health practitioners are lacking military-specific knowledge in understanding individuals within the military subculture. In addition, they are ill-equipped with interventions aimed at supporting the military family. Historically, the genogram has been an effective tool in delineating intergenerational …

Corrosion Behavior Of Copper Thin Films In Organic Hf-Containing Cleaning Solution For Semiconductor Applications, Nabil George Mistkawi, Makarem A. Hussein, Malgorzata Ziomek-Moroz, Shankar B. Rananavare

Chemistry Faculty Publications and Presentations

The corrosion behavior of electrochemically deposited copper thin films in deaerated and non-deaerated commercial cleaning solutions containing HF was investigated. Potentiodynamic polarization experiments were carried out to determine active, active–passive, passive, and transpassive regions. Corrosion rates were calculated from Tafel slopes. The addition of hydrogen peroxide to the solution and its influence on corrosion was also investigated by employing inductively coupled plasma-mass spectroscopy (ICP-MS) and X-ray photoelectron spectroscopy (XPS). The ICP-MS and potentiodynamic methods yielded comparable Cu dissolution rates. Surface analysis using atomic force microscopy and scanning electron microscopy, performed before and after the cleaning solution treatment, did not reveal …

Development Of A Contingency Capillary Wastewater Management Device, Evan A. Thomas

Mechanical and Materials Engineering Faculty Publications and Presentations

The personal body-attached liquid liquidator (PBALL) is conceived as a passive, capillary-driven, contingency wastewater disposal device. In this contingency scenario, the airflow system on the NASA crew exploration vehicle is assumed to have failed, leaving only passive hardware and vacuum vent to dispose of wastewater. To meet these needs, the PBALL was conceived to rely on capillary action and urine wetting conditions from 0° < θadv ∼ 90°, be adaptable for both male and female use, collect and retain up to 1 L of urine, minimize splash-back, and allow continuous draining of the wastewater to vacuum while minimizing cabin air loss. A subscale PBALL test article, which was tested on NASA's reduced-gravity aircraft in April 2010, successfully demonstrated key components of this design.

The manual is also suitable to be used by members of family support organizations and other individuals interested in …

Communities Of Color In Multnomah County: An Unsettling Profile, Ann Curry-Stevens, Amanda Cross-Hemmer, Coalition Of Communities Of Color

School of Social Work Faculty Publications and Presentations

Existing data that informs decision making in Multnomah County inadequately captures the lived experiences of communities of color. Rarely do existing reports include dimensions of race and ethnicity. Much research has been undertaken without the involvement of those most affected by the decisions guided by the research. The impact is that communities of color are rarely visible at the level of policy. Data has been used to obscure and oppress rather than to empower communities and eliminate disparities. This is not acceptable, and leads to inequitable policy and devastating outcomes for people of color.

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 …

Broadcast Mechanism For Improving Conditional Branch Prediction In Speculative Multithreaded Processors, Renjith Thankappan Achary Retnamma

Dissertations and Theses

ABSTRACT Many aspects of speculative multithreading have been under constant and crucial research in the recent times with the increased importance in exploiting parallelism in single thread applications. One of the important architectural optimizations that is very pertinent in this scenario is branch prediction. Branch Prediction assumes increased importance for multi-threading systems that execute threads speculatively, since wrong predictions can be much costlier here, in terms of threads, than a few instructions that occupy the pipeline in a uni-processor. Conventional branch prediction techniques have provided increasingly better prediction accuracies for uni-core processing. But the branch prediction itself takes on a …

The Design Of A Novel Tip Enhanced Near-Field Scanning Probe Microscope For Ultra-High Resolution Optical Imaging, Derek Brant Nowak

Dissertations and Theses

Traditional light microscopy suffers from the diffraction limit, which limits the spatial resolution to λ/2. The current trend in optical microscopy is the development of techniques to bypass the diffraction limit. Resolutions below 40 nm will make it possible to probe biological systems by imaging the interactions between single molecules and cell membranes. These resolutions will allow for the development of improved drug delivery mechanisms by increasing our understanding of how chemical communication within a cell occurs. The materials sciences would also benefit from these high resolutions. Nanomaterials can be analyzed with Raman spectroscopy for molecular and atomic bond information, …

The Creative Use Of Dance/Movement Therapy Processes To Transform Intrapersonal Conflicts Associated With Sexual Trauma In Women, Emily Fern Dayton

Dissertations and Theses

Abstract This qualitative research explores creative movement processes such as dance/movement therapy (DMT), authentic movement (AM), and creative dance (CD) as possible tools for transforming sexual trauma for women. Eleven movement professionals were interviewed in a semi-structured research format. My direct experience and knowledge of sexual abuse, sexual trauma, and creative movement processes are interwoven with the research question: do creative dance/movement therapy processes contribute to the dynamic of healing for women transforming sexual trauma? These findings are inconclusive for the greater population of survivors of sexual abuse and sexual trauma. However, there are indications that DMT, AM, and CD …

Anatomy Of Mishima's Most Successful Play Rokumeikan, Mami Harano

Dissertations and Theses

Mishima Yukio premiered the play Rokumeikan in 1956 and published it in 1957. For more than half a century, this play has been praised as one of the finest Japanese plays in the Post-War period. Rokumeikan is a multi-act tragic melodrama, set in 1886 (Meiji Period) in the Rokumeikan building. The play intertwines complex political cabals, intense loves and hatreds, and multiple deceptions embodying the conflict between political power and love. This essay explores the reasons why Rokumeikan has maintained its popularity over its fifty year long performance history and examines the critical reception of the play. My analysis of …

Transformative Teacher Evaluation: Self Evaluation For High Performing Teachers, Carla Ann Sosanya-Tellez

Dissertations and Theses

Public schools are in crisis, as educators and legislators seek to provide high quality education to diverse students in a measurement-driven environment. The public educator's moral imperative is to assure that all children are literate when they leave school so they can thrive in our democracy (Dewey, 1944; Freire, 1998a; Giroux & Giroux, 2004). Yet, the achievement gap persists, as poor African-American and Latino students under-perform as compared to white middle-class students (Ladson-Billings & Tate, 1995). Additionally, public school teachers are predominately middle-class and White, while they teach increasingly diverse children of poverty. In legislation, student assessment, teacher licensure, and …

A Structural And Functional Analysis Of Codeswitching In Mi Vida Gitana 'My Gypsy Life,' A Bilingual Play, Gustavo Javier Fernandez

Dissertations and Theses

The present study analyzed the language in the script of the bilingual play Mi Vida Gitana 'My Gypsy Life' (Malán, 2006) in order to better understand issues relating to codeswitching (CS). The analysis was done from a structural and a functional perspective and utilized various models developed by renowned CS scholars.

For the structural analysis, I utilized concepts and ideas put forth in the three-tiered typology created by Muysken (2000) and the Matrix Language Frame model developed by Myers-Scotton (1993). The results of this portion of the study showed that some form of CS, whether occurring between turns or within …

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. …

Globalization; But Under What Conditions? -- The Case Of The E.U., Michaelangelo Anastasiou

Dissertations and Theses

The present study explores the relationship between trust placed in national institutions and opinion of globalization. A secondary data analysis is conducted using data collected by the European Commission in a 2004 Eurobarometer survey of European Union (EU) citizens on various issues regarding the EU, globalization and national challenges. A prominent theme in the literature is that, in recent times, globalization has had the effect of compromising the sovereignty of nation-states. This has generated a backlash of nationalistic attitudes wherein globalization is posited in opposition to the nation-state. This surge in nationalism has reinforced a culture wherein any external force …

Investigation Of Speech Samples From Typically Developing Preschool Age Children: A Comparison Of Single Words And Imitated Sentences Elicited With The Paba-E, Matthew William Olsen

Dissertations and Theses

Assessment of speech sound production in young children provides the basis for diagnosis and treatment of speech sound disorders. Standardized single-word articulation tests are typically used for identification of speech sound errors because they can provide an efficient means of obtaining a speech sample for analysis and comparison to same-age peers. A major criticism of single-word articulation tests is that they may not accurately reflect speech sound production abilities in conversation. Comparison of performance in single-word and conversational contexts has produced conflicting results in the available research.

The purpose of the present study was to compare speech samples obtained using …

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 …

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 …
