Asset Mapping: Community Geography Project

The goals for this project entailed collecting both quantitative and qualitative data about selected neighborhoods in Portland. The quantitative data included photo documentation of all buildings and lots (e.g. parking lots or vacant lots) within the study areas. Other empirical data collected included the address(es) of the buildings, the number of stories and/or mailboxes, land use categories such as commercial or residential (including exclusive as well as mixed use categories), the name and type of business, and the spatial coordinates of the building (latitude/longitude). This data was collected in order to provide an objective "picture" of the neighborhood at a …

Institute for Sustainable Solutions Publications and Presentations

Making trade-offs between ecological services and other contributors to human well-being is a difficult but critical process that requires valuation. This allows both better recognition of the ecological, social, and economic trade-offs and also allows us to bill those who use up or destroy ecological services and reward those that produce or enhance them. It also aids improved ecosystems policy. In this paper we clarify some of the controversies in defining the contributions to human well-being from functioning ecosystems, many of which people are not even aware of.We go on to describe the applicability of the various valuation methods that …

In Situ Enrichment Of Ocean Crust Microbes On Igneous Minerals And Glasses Using An Osmotic Flow‐Through Device, Amy Renee Smith, Martin Fisk, Radu Popa, Mark Nielsen, C. Geoffrey Wheat, Hans W. Jannasch, Andrew T. Fisher, Keir Becker, Stefan M. Sievert, Gilberto Flores

Biology Faculty Publications and Presentations

The Integrated Ocean Drilling Program (IODP) Hole 1301A on the eastern flank of Juan de Fuca Ridge was used in the first long-term deployment of microbial enrichment flow cells using osmotically driven pumps in a subseafloor borehole. Three novel osmotically driven colonization systems with unidirectional flow were deployed in the borehole and incubated for 4 years to determine the microbial colonization preferences for 12 minerals and glasses present in igneous rocks. Following recovery of the colonization systems, we measured cell density on the minerals and glasses by fluorescent staining and direct counting and found some significant differences between mineral samples. …

Growth Phase-Dependent Gene Regulation In Vivo In Sulfolobus Solfataricus, Melissa Deyoung, Michelle Thayer, John Van Der Oost, Kenneth M. Stedman

Biology Faculty Publications and Presentations

Ribosomal genes are strongly regulated dependent on growth phase in all organisms, but this regulation is poorly understood in Archaea. Moreover, very little is known about growth phase-dependent gene regulation in Archaea. SSV1- based lacS reporter gene constructs containing the Sulfolobus 16S/23S rRNA gene core promoter, the TF55a core promoter, or the native lacS promoter were tested in Sulfolobus solfataricus cells lacking the lacS gene. The 42-bp 16S/23S rRNA gene and 39-bp TF55a core promoters are sufficient for gene expression in S. solfataricus. However, only gene expression driven by the 16S/23S rRNA gene core promoter is dependent on …

Leadership In Sustainable Chemicals Policy: Opportunities For Oregon, Jennifer H. Allen, Alexis Dinno

Institute for Sustainable Solutions Publications and Presentations

Oregon is uniquely positioned to lead in the development of safer alternatives to toxic chemicals. Existing chemicals policy in the United States does not comprehensively protect human health or the environment from the potential impacts of chemical exposure. Very few of the 84,000 chemical substances produced, processed or imported for commercial purposes in the United States have been studied for health and environmental impacts. The federal Environmental Protection Agency has access to only limited information about potential health or environmental hazards. Manufacturers have the right to withhold what they consider to be confidential business information. Because of this lack of …

A Three-Step Method For Teaching The Principles Of Evolution To Non-Biology Major Undergraduates, Cameron M. Smith

Anthropology Faculty Publications and Presentations

A method for teaching the principles of evolution in a 50-minute lecture for undergraduate non-biology majors is described. The method “unpacks” evolution into three observable, factual occurrences: replication (R, reproduction), variation (V, differences between parent and offspring and siblings), and selection (S, nonrandom differential survival of offspring). This method has been particularly effective in demonstrating to students that evolution is the factual, unintended consequence of three independent phenomena (R, V, S).

Review Of Race And Politics: Asian Americans, Latinos, And Whites In A Los Angeles Suburb, Albert Pham

Anthós

In this review of Race and Politics: Asian Americans, Latinos, and Whites in a Los Angeles Suburb by Leland Saito, I discuss and analyze Saito’s argument, and his use of supporting evidence. I also discuss the fit between the argument and evidence, as well as the strengths and weaknesses of his sources, methods, and interpretation. In doing so, I situate Saito’s work into context with similar works examining the relationship between spatial practices and racial formation.

Tension Directly Stabilizes Reconstituted Kinetochore-Microtubule Attachments, Bungo Akiyoshi, Krishna K. Sarangapani, Andrew F. Powers, Christian R. Nelson, Steve Reichow, Hugo Arellano-Santoyo, Tamir Gonen, Jeffrey A. Ranish, Charles L. Asbury, Sue Biggins

Chemistry Faculty Publications and Presentations

Kinetochores are macromolecular machines that couple chromosomes to dynamic microtubule tips during cell division, thereby generating force to segregate the chromosomes. Accurate segregation depends on selective stabilization of correct ‘bi-oriented’ kinetochore-microtubule attachments, which come under tension due to opposing forces exerted by microtubules. Tension is thought to stabilize these bi-oriented attachments indirectly, by suppressing the destabilizing activity of a kinase, Aurora B. However, a complete mechanistic understanding of the role of tension requires reconstitution of kinetochore-microtubule attachments for biochemical and biophysical analyses in vitro. Here we show that native kinetochore particles retaining the majority of kinetochore proteins can be …

The Femme Fatale And The Exotic Queer Within Shinya Tuskamoto's Tetsuo: Gender As Narrative Tool Within An Allegory For Post Wwii Japan's Industrialized Identity Crisis, Nickolus Walters

Anthós

Within Shinya Tsukamoto’s seminal independent horror masterpiece Tetsuo, the viewer’s perceptions of reality and the present are distorted within a temporally disjointed blend of horrific fantasy and banal existence; this instability reflects the vocal and subconscious critiques of historical ontological truths exhibited within the emergent transnational genres of Japanese cyberpunk and American Avant-pop ideologies of the late 1980’s. Author Takayuki Tatsumi uses Shinya Tsukamoto's Tetsuo to illustrate the emergence of the "Japanoid," a technologically driven fusion of American and Japanese post-war identity best understood as a manifestation of Donna Haraway's socio-political "cyborg." Tatsumi strongly advises avoiding interpretation through a "queer" …

Resource Maps For Fresh Meat Across Retail And Wholesale Supply Chains, Peter Whitehead, Martin Palmer, Carlos Mena, Adrian Williams, Christine Walsh

Business Faculty Publications and Presentations

Consumers spend more money on meat than any other food item. WRAP has already shown that households are wasting around 570,000 tonnes of fresh meat each year, of which 260,000 (46%) is avoidable with a value of about £1,300M. These wasted products also include embedded water and embedded carbon. This research has focused on the supply of meat from the farm gate onwards, including livestock slaughtering, meat preparation, processing and packaging, distribution and retail. It focuses on fresh meat from the four animal species which comprise some 96% by weight of all animals slaughtered for human consumption, namely chickens, cattle, …

Assessment Of The Hydrologic Response To Climate Change In The Upper Deschutes River Basin, Central Oregon, Heejun Chang, M. Scott Waibel, Marshall W. Gannett, Christina L. Hulbe

Geography Faculty Publications and Presentations

Effects of climate change in the Cascade Range will likely include more rain, less snow, and earlier snowmelt in the Cascade Range as compared to present conditions. These changes, in turn, will affect the timing of runoff, groundwater recharge, and groundwater discharge to spring-fed streams. This hydrologic response needs to be examined and understood due to implications for water management. In this study, a water- and energy-balance model was used to explore 21st century changes in the water budget in the upper Deschutes Basin, and a groundwater model was used to evaluate the response of the groundwater system to those …

Climate Change And Climate Variability: Personal Motivation For Adaptation And Mitigation, Jan C. Semenza, George B. Ploubidis, Linda Acha George

Environmental Science and Management Faculty Publications and Presentations

Background: Global climate change impacts on human and natural systems are predicted to be severe, far reaching, and to affect the most physically and economically vulnerable disproportionately. Society can respond to these threats through two strategies: mitigation and adaptation. Industry, commerce, and government play indispensable roles in these actions but so do individuals, if they are receptive to behavior change. We explored whether the health frame can be used as a context to motivate behavioral reductions of greenhouse gas emissions and adaptation measures. Methods: In 2008, we conducted a cross-sectional survey in the United States using random digit dialing. Personal …

Quantum Phase Estimation Using Multivalued Logic, Marek Perkowski, Vamsi Parasa

Electrical and Computer Engineering Faculty Publications and Presentations

We generalize the Quantum Phase Estimation algorithm to MVL logic. We show the quantum circuits for QPE using qudits. We derive the performance requirements of the QPE to achieve high probability of success. We show how this leads to logarithmic decrease in the number of qudits and exponential decrease in error probability of the QPE algorithm as the value of the radix d increases.
