Business Faculty Publications and Presentations

Brett Beach and Tim McCollum, co-founders of Madécasse, spent two years as Peace Corps volunteers in Madagascar. During that time, they fell in love with the country and its people. Recognizing the need of the Malagasy for stable jobs and fair wages and the connection between poverty and environmental destruction, Brett and Tim discussed possibilities for a social enterprise in the country.

Madagascar presents a beautiful yet challenging place to operate a business. It has a wide range of flora and fauna, approximately 70% of which are found nowhere else on Earth and it produces coffee, vanilla, sugar, cotton, pepper, …

Aqueous Red-Emitting Silicon Nanoparticles For Cellular Imaging: Consequences Of Protecting Against Surface Passivation By Hydroxide And Water For Stable Red Emission, Sheng-Kuei Chiu, Beth Ann Manhat, William J.I. Debenedetti, Anna L. Brown, Katye Fichter, Tania Vu, Micah Eastman, Jun Jiao, Andrea Mitchell Goforth

Chemistry Faculty Publications and Presentations

Stable, aqueous, red-to-near infrared emission is critical for the use of silicon nanoparticles (Si NPs) in biological fluorescence assays, but such Si NPs have been difficult to attain. We report a synthesis and surface modification strategy that protects Si NPs and preserves red photoluminescence (PL) in water for more than 6 mo. The Si NPs were synthesized via high temperature reaction, liberated from an oxide matrix, and functionalized via hydrosilylation to yield hydrophobic particles. The hydrophobic Si NPs were phase transferred to water using the surfactant cetyltrimethylammonium bromide (CTAB) with retention of red PL. CTAB apparently serves a double role …

Automated Extraction And Classification Of Time-Frequency Contours In Humpback Vocalizations, Hui Ou, Whitlow W.L. Au, Lisa M. Zurk, Marc O. Lammers

Electrical and Computer Engineering Faculty Publications and Presentations

A time-frequency contour extraction and classification algorithm was created to analyze humpback whale vocalizations. The algorithm automatically extracted contours of whale vocalization units by searching for gray-level discontinuities in the spectrogram images. The unit-to-unit similarity was quantified by cross-correlating the contour lines. A library of distinctive humpback units was then generated by applying an unsupervised, cluster-based learning algorithm. The purpose of this study was to provide a fast and automated feature selection tool to describe the vocal signatures of animal groups. This approach could benefit a variety of applications such as species description, identification, and evolution of song structures. The …

Insights And Blind Spots: A Qualitative Analysis Of Risk In Psychiatric Security Review Board Hearings, Abby Kealani Balfour

Dissertations and Theses

The prevalence and consequences of the insanity plea, titled "guilty except for insanity" in the State of Oregon, are fraught with misconceptions. The use of the plea requires a complex set of interactions between the mental health and criminal justice systems, and comes with severe costs for people who use it. Most of the research on the psychological aspects of the insanity plea emphasizes empirical validity in the form of risk assessment instruments and/or the biomedical model with its focus on disease and illness. This thesis analyzes from community psychology and critical theory perspectives the decision process of hearings held …

Rethinking Information Literacy In A Globalized World, Laurie Kutner, Alison Armstrong

Communications in Information Literacy

As a profession, librarians have an important and unique role to play in higher education in producing information literate students equipped to be successful in a complex, twenty-first century global society. It is our contention that our guiding professional information literacy definitions and standards need to be reconsidered in order to remain relevant within the global learning context. Our preliminary conclusion is that the predominantly skills-based approach facilitated by the current ACRL Information Literacy Competency Standards for Higher Education, is not sufficient to facilitate teaching of twenty-first century "deep information literacy," which we feel encompasses additional content-based engagement with the …

Considering Information Literacy Skills And Needs: Designing Library Instruction For The Online Learner, Swapna Kumar, Marilyn Ochoa, Mary Edwards

Communications in Information Literacy

This paper reports on a library instruction needs assessment conducted with incoming doctoral students (n=34) in two online programs in education. The differences in the prior skills and experiences of the two groups highlighted the importance of both needs assessments and learner analysis as well as course- or program-specific instructional design in information literacy instruction for online students. Based on students' reported skills, education librarians structured both the content and format of instruction to help students succeed in online activities in the doctoral program.

Predictors Of Student's Attitudes Toward Science Literacy, Irina I. Holden

Communications in Information Literacy

Being information and science literate are crucial in an age when scientific developments influence the political arena and vice versa. In order to become active and responsible citizens, students must understand such issues as global warming and stem cell research. Furthermore, they must be lifelong learners, capable of researching and educating themselves about new scientific developments. These are some of the complex issues that information literacy educators must address. This article reports on the results of a survey of student's attitudes towards science literacy and lifelong learning, and on variables associated with their attitudes. Most of the students' attitudes were …

Information Literacy On The Web: How College Students Use Visual And Textual Cues To Assess Credibility On Health Websites, Katrina L. Pariera

Communications in Information Literacy

One of the most important literacy skills in today's information society is the ability to determine the credibility of online information. Users sort through a staggering number of websites while discerning which will provide satisfactory information. In this study, 70 college students assessed the credibility of health websites with a low and high design quality, in either low or high credibility groups. The study's purpose was to understand if students relied more on textual or visual cues in determining credibility, and to understand if this affected their recall of those cues later. The results indicate that when viewing a high …

Cytoskeletal Strains In Modeled Optohydrodynamically Stressed Healthy And Diseased Biological Cells, Sean S. Kohles, Yu Liang, Asit K. Saha

Mechanical and Materials Engineering Faculty Publications and Presentations

Controlled external chemomechanical stimuli have been shown to influence cellular and tissue regeneration/degeneration, especially with regards to distinct disease sequelae or health maintenance. Recently, a unique three-dimensional stress state was mathematically derived to describe the experimental stresses applied to isolated living cells suspended in an optohydrodynamic trap (optical tweezers combined with microfluidics). These formulae were previously developed in two and three dimensions from the fundamental equations describing creeping flows past a suspended sphere. The objective of the current study is to determine the full-field cellular strain response due to the applied three-dimensional stress environment through a multiphysics computational simulation. In …

Transgressing Sexuality: An Interdisciplinary Study Of Economic History, Anthropology, And Queer Theory, Jason Gary Damron

Dissertations and Theses

This interdisciplinary thesis examines the concept of sexuality through lenses provided by economic history, anthropology, and queer theory. A close reading reveals historical parallels from the late 1800s between concepts of a desiring, utility-maximizing economic subject on the one hand, and a desiring, carnally decisive sexological subject on the other. Social constructionists have persuasively argued that social and economic elites deploy the discourse of sexuality as a technique of discipline and social control in class- and gender-based struggles. Although prior scholarship discusses how contemporary ideas of sexuality reflect this origin, many anthropologists and queer theorists continue to use "sexuality" uncritically …

Portland's "Refugee From Occupied Hollywood": Andries Deinum, His Center For The Moving Image, And Film Education In The United States, Heather Oriana Petrocelli

Dissertations and Theses

Two years after Dutch émigré Andries Deinum was fired from the University of Southern California in 1955 for refusing to cooperate with the House Un-American Activities Committee, he moved to Portland, Oregon to teach film courses through the Portland Extension Center. By 1969 he had become integral to the local film community and had formed Portland State University's Center for the Moving Image (CMI), where he and Tom Taylor taught film history, criticism, and production for the next thirteen years. Although CMI was eliminated in 1981 as part of PSU's financial exigency, CMI's teachers and students have been a vital …

The Hanford Advisory Board: A Case Study In Democracy, Technology, And Representation, Alexander Sager, Alex Zakaras

Philosophy Faculty Publications and Presentations

Highly technical policy decisions present daunting challenges for democracy. In order to hold public officials accountable, citizens must be able to see how policy decisions stand to affect their interests. If they are unable to do so, they can find themselves exposed to bureaucratic domination through the discretionary power of bureaucrats, scientists, or policy experts. One of the major tasks of empirically informed democratic theory is to analyze and evaluate practices and institutions that use public participation to try to render highly technical public decision-making more accountable to the public, and therefore more legitimate. This paper presents a case study …

Chemistry Faculty Publications and Presentations

Thiols are important molecules in the environment and in biological processes. Cysteine (Cys), homocysteine (Hcy), glutathione (GSH) and hydrogen sulfide (H2S) play critical roles in a variety of physiological and pathological processes. The selective detection of thiols using reaction-based probes and sensors is very important in basic research and in disease diagnosis. This review focuses on the design of fluorescent and colorimetric probes and sensors for thiol detection. Thiol detection methods include probes and labeling agents based on nucleophilic addition and substitution, Michael addition, disulfide bond or Se-N bond cleavage, metal-sulfur interactions and more. Probes for H2S are based on …

Comedy As A Feminist Rhetoric, Liz Lemon Style, Risa Polansky Shiman

Harlot: A Revealing Look at the Arts of Persuasion

Given the stereotypes that come along with traditional feminist activism – She's a feminist. She looks angry, and I can see from here she's not wearing a bra – and the frustration feminists often face as a result, comedy is an entertaining, and therefore presumably palatable, way to expose contemporary feminist issues to broad audiences. But is it effective? A fan of ironic, silly, and sometimes (shhh, don't tell) lewd humor, I'm no stranger to The Looks, which range from “I don't get it" to “You're not as funny as you think you are" to “I am both disgusted and …

Pam Meal Ticket Cookbook, Lexa Walsh

Meal Ticket

Created by Lexa Walsh and the staff of Portland Art Museum

Meal Ticket was a monthly silo-busting luncheon with the staff of the Museum. The luncheon provided a level playing field for staff of every department, in a boardroom usually saved for Trustees and upper management, in an organization that normally has a strict hierarchy. Anyone was welcome to a home cooked meal, replete with seating charts and wine glasses. Guests were seated to encourage cross- departmental exchange, for example seating someone from security across from someone from accounting, someone from education across from someone from events. We employed a …

Decay Rates Of A Molecule In The Vicinity Of A Spherical Surface Of An Isotropic Magnetodielectric Material, H. Y. Chung, P.T. Leung, D. P. Tsai

Physics Faculty Publications and Presentations

A comprehensive study is presented on the decay rates of excited molecules in the vicinity of a magnetodielectric material of spherical geometry via electrodynamic modeling. Both the models based on a driven-damped harmonic oscillator and on energy transfers will be applied so that the total decay rates can be rigorously decomposed into the radiative and the nonradiative rates. Clarifications of the equivalence of these two models for arbitrary geometry will be provided. Different possible orientations and locations of the molecule are studied with the molecule being placed near a spherical particle or a cavity. Among other results, TE modes are …

Experimental Validation Of Phase Using Nomarski Microscopy With An Extended Fried Algorithm, Scott A. Prahl, Amanda Dayton, Kyle Juedes, Erik J. Sánchez, Rafael Paez López, Donald D. Duncan

Electrical and Computer Engineering Faculty Publications and Presentations

Reconstruction of an image (or shape or wavefront) from measurements of the derivatives of the image in two orthogonal directions is a common problem. We demonstrate how a particular reconstructor, commonly referred to as the Fried algorithm, can be used with megapixel derivative images to recover the original image. Large datasets are handled by breaking the derivative images into smaller tiles, applying the Fried algorithm and stitching the tiles back together. The performance of the algorithm is demonstrated using differential interference contrast microscopy on a known test object.

Troublesome Concepts And Information Literacy: Investigating Threshold Concepts For Il Instruction, Amy R. Hofer, Lori Townsend, Korey Brunetti

Library Faculty and Staff Publications and Presentations

Librarians regularly encounter students who struggle to understand and apply information literacy concepts. A qualitative survey administered to information literacy practitioners asked about troublesome content and analyzed results using the threshold concepts pedagogical framework first described by Jan Meyer and Ray Land. A threshold concept transforms the learner’s view of content and helps integrate previously learned material; threshold concepts are portals that, once traversed, bring insight into how to think and act like a practitioner within a discipline. This project uses the data collected to propose seven threshold concepts for information literacy.

Ida B. Wells-Barnett And The Carceral State, Patricia A. Schechter

History Faculty Publications and Presentations

My remarks today are entitled "Ida B. Wells-Barnett and the Carceral State." I want to focus on the carceral state—that is, the government functions of 'confining, surveillance and punishment'—in order to engage with some recent scholarship on race, policing, and imprisonment in the United States. These are topics that Wells-Barnett had a great deal to say about hundred years ago, especially as related to lynching. I’d like to suggest that her work in prison reform, probation work, and advocacy for inmates back in the progressive era connects to the contemporary crisis around race and mass incarceration in important ways.

The Semiotic Ecology And Linguistic Complexity Of An Online Game World, Steven L. Thorne, Ingrid Fischer, Xiaofei Lu

World Languages and Literatures Faculty Publications and Presentations

Multiplayer online games form complex semiotic ecologies that include game-generated texts, player-to-player communication and collaboration, and associated websites that support in-game play. This article describes an exploratory study of the massively multiplayer online game (MMO) World of Warcraft (WoW), with specific attention to its qualities as a setting for second language (L2) use and development. This empirical study seeks to answer the following question: What is the nature of the linguistic ecology that WoW players are exposed to? Many studies have described the developmental opportunities presented by commercially available gaming environments (e.g., Gee, 2003, 2007), their value as sites of …
