Non-Planar On-Shell Diagrams, Sebastían Franco, Daniele Galloni, Brenda Penante, Congkao Wen

Publications and Research

We initiate a systematic study of non-planar on-shell diagrams in N = 4 SYM and develop powerful technology for doing so. We introduce canonical variables generalizing face variables, which make the d log form of the on-shell form explicit. We make significant progress towards a general classification of arbitrary on-shell diagrams by means of two classes of combinatorial objects: generalized matching and matroid polytopes. We propose a boundary measurement that connects general on-shell diagrams to the Grassmannian. Our proposal exhibits two important and non-trivial properties: positivity in the planar case and it matches the combinatorial description of the diagrams in …

Primitive At The Plantation's Edge, Robert F. Reid-Pharr

Publications and Research

There comes a time when the only thing that one can do is admit defeat. Standing at the tail end of a Black Studies movement established as part of the articulation of anti-segregationist, anti-colonialist African and African American political and cultural insurgencies, one is made painfully aware of a sort of necessary and inevitable social and professional marginalization structuring the everyday existence of the so-called black scholar. The broadly imagined ethical outlines of even the most valued projects of black intellectualism continue as ornamental, overly moralistic, never quite fully valid aspects of the industry / government / education complex that …

Effect Of Economic Freedom On Social Capital Panel Evidence From U.S. Contiguous States, Aka Kyaw Min Maw

Agribusiness and Applied Economics

This thesis examines the relationship between economic freedom and social capital in U.S. contiguous states from the 1980s to the 2000s as there is a shortcoming of literature on the topic. This study develops a composite social capital index that captures important aspects of social capital such as voter turnout, social trust, informal socialization and religious participation. This study finds that the changes in subnational level economic freedom measures have positive significant effects on social capital while the levels of economic freedom measures have no significant effect on social capital. Moreover, no significant link between all government level economic freedom …

Urban Studies and Planning Faculty Publications and Presentations

Portland State University’s Community Environmental Services (CES) has helped shape the Portland metropolitan region’s sustainable materials management practices for more than twenty-five years. CES’s research and program development services have benefited community partners that in turn have provided hundreds of students with rich educational experiences. PSU faculty members also advance their pedagogical and research agendas through the development of CES-affiliated capstone courses. This article explores the CES co-production model from the perspectives of students, faculty members, and community partners.

Revisiting Rajneeshpuram: Oregon's Largest Utopian Community As Western History, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

Between 1981 and 1985, the intentional community of Rajneeshpuram near Antelope, Oregon, hosted up to 15,000 followers of Bhagwan Shree Rajneesh, a spiritual leader from Pune, India. In this essay, Carl Abbott examines the rise and fall of Rajneeshpuram within the context of western history, which “centers on the processes of migration, settlement, displacement, and rearrangement.” Drawing parallels to earlier religious closed communities, such nineteenth century Mormon settlements, Abbott describes how Rajneeshees fit into the “overarching storylines of frontier utopias and the…narrative of settler colonialism.” Unlike Mormon communities, however, Abbott concludes that Rajneeshpuram ultimately failed because its leaders were not …

Integrating Information Literacy, The Pogil Method, And Ipads Into A Foundational Studies Program, Carrie Moore, Jennifer Black, Barbara C. Glackin, Margie Ruppel, Elaine Watson

Library Faculty and Staff Publications and Presentations

This article provides an overview of the design, implementation, revision and informal assessment of an information literacy curriculum embedded in a new University Foundations (UF) program at a mid‐sized public university. The library information literacy sessions incorporated teambased learning and Process Oriented Guided Inquiry Learning (POGIL) elements using iPads. Each session provided students an opportunity to develop and apply information literacy skills, and included critical thinking questions which led students to think about underlying concepts. A focus group with the librarians assessed the UF library curriculum, its impact on student engagement, and the training activities for librarian teaching preparation.

University Studies Annual Assessment 2014-2015, Rowanna L. Carpenter, J.R. Estes, Celine Fitzmaurice, Seanna M. Kerrigan, Annie Knepler, Dana Lundell, Neera Malhotra, Vicki Reitenauer, Erika Schnatz

University Studies Annual Assessment Reports

During the 14-15 academic year, University Studies (UNST) adopted a “Goal of the Year,” communication. We introduced a new writing rubric, piloted the rubric and used it to review Freshman Inquiry (FRINQ) ePortfolios and Sophomore Inquiry (SINQ) writing samples. We investigated the usefulness of the rubric, the types of writing being asked of our students and how well our students’ writing reflects our expectations for their learning. At the Capstone level, we expanded our course ePortfolio assessment approach to include intentional faculty conversations about how they address the goal of communication in their courses. We continue to be interested in …

Psychometric Evaluation Of Lexical Diversity Indices: Assessing Length Effects, Gerasimos Fergadiotis, Heather Harris Wright, Samuel B. Green

Speech and Hearing Sciences Faculty Publications and Presentations

Purpose—Several novel techniques have been developed recently to assess the breadth of speaker’s vocabulary exhibited in a language sample. The specific aim of this study was to increase our understanding of the validity of the scores generated by different lexical diversity (LD) estimation techniques. Four techniques were explored: D, Maas, Measure of Textual Lexical Diversity (MTLD), and the Moving Average Type Token Ratio (MATTR).

Method—Four LD indices were estimated for language samples on four discourse tasks (procedures, eventcasts, story retell, and recounts) from 442 neurologically intact adults. The resulting data were analyzed using structural equation modeling.

Results—The scores on the …

The Cacaio Project: Education For Environmental, Aesthetic And Moral Development, Atila T. Calvente

Contemporary Aesthetics (Journal Archive)

Economic inequalities, institutional awkwardness, cultural underdevelopment, social exclusion, a fast rate of environmental, ecological, and biodiversity degradation have all been at the root of historic social injustice and structural poverty in Brazil for centuries. Human development and emancipation in this context should be approached as a set of non-formal educational practices to promote better learning and dignity. These would become potent means for reducing material poverty and selfish individual behavior, and for improving holistic modes of education and culture. Non-traditional educational practices can have an important influence in state-run schools, as well as in private schools, by enhancing resilience and …

Epistemic Function And Ontology Of Analog And Digital Images, Aleksandra Lukaszewicz Alcarez

Contemporary Aesthetics (Journal Archive)

The important epistemic function of photographic images is their active role in construction and reconstruction of our beliefs concerning the world and human identity, since we often consider photographs as presenting reality or even the Real itself. Because photography can convince people of how different social and ethnic groups and even they themselves look, documentary projects and the dissemination of photographic practices supported the transition from disciplinary society to the present-day society of control. While both analog and digital images are formed from the same basic materia, the ways in which this matter appears are distinctive. In the case of …

Is There A "Duty To Read"?, Charles L. Knapp

Faculty Scholarship

The notion that there is in general contract law a "duty to read" persists in the decisions of American courts. This Article explores the general question of what it may mean to say that there is a "duty to read," and concludes by suggesting what role (if any) that doctrine should play in our present-day law of contract. The Article begins by examining various ways in which the "duty to read" is commonly articulated, and compares it to other contract law concepts: the "duty to bargain in good faith" and the "duty to mitigate damages." The Article next considers a …

This poem by José Angel Araguz originally appeared in Apply Valley Review: A Journal of Contemporary Literature.

José Angel Araguz comments on "Canicas":
I fear being one of the last generations to play with marbles. This isn’t a statement of nostalgia or one bemoaning how times change. I mean simply in terms of the reference of the game and the scene. These days, birds fly over our cell phone screens without us noticing.

An Ornithological Investigation Of The Relationships Among Species Assemblages In Diverse Landscapes In Portland, Oregon, Trevor Attenberg

Environmental Science and Management Professional Master's Project Reports

This study involves geographic variables of the urban landscape and how they affect bird species assemblage. I utilized bird point count data from observation sites in the Portland, OR metropolitan region provided by Portland Environmental Services. Species data and its relationship with environmental variables were evaluated using Bray-Curtis Dissimilarity measurements together with Non-metric Multidimensional scaling (NMDS) to provide a clear image of the spatial relationships between sites. Land classification, water and canopy in 500 m buffers were quantified in order to describe important geographic variability among collection areas of bird data. Patterns indicating spatial trends in the urban landscape emerged. …

Explaining The "Pulse Of Protoplasm": The Search For Molecular Mechanisms Of Protoplasmic Streaming, Michael Dietrich

Dartmouth Scholarship

Explanations for protoplasmic streaming began with appeals to contraction in the eighteenth century and ended with appeals to contraction in the twentieth. During the intervening years, biologists proposed a diverse array of mechanisms for streaming motions. This paper focuses on the re-emergence of contraction among the molecular mechanisms proposed for protoplasmic streaming during the twentieth century. The revival of contraction is a result of a broader transition from colloidal chemistry to a macromolecular approach to the chemistry of proteins, the recognition of the phenomena of shuttle streaming and the pulse of protoplasm, and the influential analogy between protoplasmic streaming and …

Interactional Practices And Artifact Orientation In Mobile Augmented Reality Game Play, Steven L. Thorne, John Hellermann, Adam Jones, Daniel Lester

World Languages and Literatures Faculty Publications and Presentations

In an effort to better understand the ways that small groups use digital technology as they move through a physical environment, this paper describes the methods used by groups of three people to maintain a group participation structure as they accomplish a quest-type task during mobile augmented reality game play. The game was available on one mobile digital device (an Apple iPhone) that was shared by three players as they negotiated a set of point-to-point route finding tasks. Video-recordings of each group were made using three cameras (two head-mounted cameras and one hand-held camera). We focus on the different ways …
