Synthesis And Characterization Of N- And P- Doped Tin Oxide Nanowires, Hoang Tran, Shankar B. Rananavare

Chemistry Faculty Publications and Presentations

Bulk-scale synthetic methods for preparing doped tin oxide (SnO₂) nanowires (NWs) are presented. n-and p-doping is achieved through insertion of Antimony and Lithium in tin oxide lattice, respectively. We also present a comparison of the structural and optical properties of SnO₂ nanoparticles (NPs), and SnO₂ NWs. Both n-type and p- type NWs display a characteristic red shift in their photoluminescence (PL) spectra. Surface plasmons observed in these systems imply high carrier concentrations. These corrosion resistant materials are useful in fabricating ultra-sensitive gas detectors and transparent electronics.

Effectiveness Of Forest Management Strategies To Mitigate Effects Of Global Change In South-Central Siberia, Eric J. Gustafson, Anatoly Z. Shvidenko, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

We investigated questions about the ability of broad silvicultural strategies to achieve multiple objectives (reduce disturbance losses, maintain the abundance of preferred species, mitigate fragmentation and loss of age-class diversity, and sequester aboveground carbon) under future climate conditions in Siberia. We conducted a factorial experiment using the LANDIS-II landscape disturbance and succession model. Treatments included varying the size and amount of areas cut and the cutting method (selective or clearcut). Simultaneously, the model simulated natural disturbances (fire, wind, insect out-breaks) and forest succession under projected future climate conditions as predicted by an ensemble of global circulation models. The cutting method …

Planning Approaches For Water Resources Development In The Lower Mekong Basin, Robert Costanza, Ida Kubiszewski, Peter Paquet, Jeffrey King, Shpresa Halimi, Hansa Sanguanngoi, Nguyen Luong Bach, Richard Frankel, Jiragorn Ganaseni, Apisom Intralawan, David Morell

Institute for Sustainable Solutions Publications and Presentations

Governments in the Lower Mekong Basin (LMB) face decisions that involve trade-offs between, for example, the economic benefits from hydropower generation and potentially irreversible negative impacts on the ecosystems that provide livelihoods and food security to the rural poor. These decisions involve complex problems that are both poorly understood in scientific terms and subject to rapid, potentially catastrophic change over time. A comprehensive, whole systems approach that adequately addresses the risks and uncertainties involved is necessary, but this is a daunting challenge for researchers, decision makers, and managers. They must develop the capacity to plan, coordinate, and implement a program …

Prevention Of Identity Theft: A Review Of The Literature, Portland State University. Criminology And Criminal Justice Senior Capstone

Criminology and Criminal Justice Senior Capstone Project

With advances in technology and increases in impersonal electronic transactions, identity theft IT) is becoming a major problem in today’s society. One may ask why IT is growing in America. The answer is simple, as a review of literature reveals: IT is extremely hard to detect, prevent, and prosecute.

There are many ways people can protect themselves, their identities and secure their personal information; many do not concern themselves with this knowledge, however, until they become victims of this crime, themselves. With advances in technology, offenders are often turning to new methods to access information and use it for financial …

A System Dynamics Model Of Pharmaceutical Opioids: Medical Use, Diversion, And Nonmedical Use, Teresa Schmidt, Wayne Wakeland, J. David Haddox

Complex Systems Faculty Publications and Presentations

A dramatic rise in the nonmedical of pharmaceutical opioids has presented the United States with a substantial public health problem. Nonmedical use of prescription pain relievers has become increasingly prevalent in the US over the last two decades, and diversion of medicines obtained by prescription is assumed to be a major source of supply for nonmedical opioid use. Policymakers striving to protect population health by ameliorating the adverse outcomes of nonmedical use of opioid analgesics could benefit from a systems-level model which reflects the complexity of the system and incorporates the full range of available data. To address this need, …

Calibration Of Complex System Dynamics Models: A Practioner's Report, Rod Walker, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

This paper is not a typical academic paper that is solidly grounded in the literature. Instead, this paper reports practitioner’s experiences in rebuilding and calibrating a very large system dynamics model. A prior version of this model had been in use for over 10 years in an ongoing executive training simulation. That model had never worked correctly in several key areas, requiring the outputs to be manually adjusted by very experienced facilitators during the course of the simulation. The present project rebuilt the system dynamics model, redesigned the parts that weren’t working, and calibrated the resulting model to match the …

Bridging The Marine–Terrestrial Disconnect To Improve Marine Coastal Zone Science And Management, Benjamin I. Ruttenberg, Elise F. Granek

Environmental Science and Management Faculty Publications and Presentations

Coastal zone ecosystems sit between larger terrestrial and marine environments and, therefore, are strongly affected by processes occurring in both systems. Marine coastal zone systems provide a range of benefits to humans, and yet many have been significantly degraded as a result of direct and indirect human impacts. Management efforts have been hampered by disconnects both between management and scientific research and across linked marine–terrestrial systems. Management jurisdictions often start or end at the shoreline, and multiple agencies at different levels of government often have overlapping or conflicting management goals or priorities, or suffer from a lack of knowledge or …

Fair Trade And Development: A Changing Paradigm, Daniel Jaffee

Sociology Faculty Publications and Presentations

Book chapter.

By the time the fair trade movement celebrated the 20th anniversary of its founding in 2008, it had been transformed virtually beyond recognition. From a marginal European movement characterized by small ethical companies, non-profit charities, solidarity groups and alternative trading organizations (ATOs) selling coffee and handicrafts to a small group of politicized consumers through alternative world shops, fair trade has become an international market system with annual sales of nearly US $5,000m. (€3,500m.) (FLO 2010), reaching mass audiences of mainstream shoppers across the global North with a wide range of food and non-food products originating from both small …

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 …

Embedding Parallel Computation In A Stochastic Mesh Network: A Morphogenetic Approach, Max Orhai

Anthós

Many basic techniques in computer science have been founded on the assumption that physical computing resources are scarce but orderly, and that the cost of effective direct communication between physically distant parts of a computer system is affordable. In ubiquitous computing systems such as sensor networks, or in the design of nano-scale systems, these familiar assumptions may not hold.

What if we suppose instead that computing capacity is plentiful, but that only local communication is possible, and the exact structure of the communication network is not known in advance? This is the domain of spatial programming.

How can we program …

Aphorism's Destructive Capacity Towards Logocentric Text In Friedrich Nietzsche's Thus Spake Zarathustra, Joseph Van Der Naald

Anthós

The "spirit of gravity" and all of its connotations is central to the writings of Friedrich Nietzsche. In Nietzsche's Thus Spake Zarathustra, Zarathustra proclaims that the spirit of gravity is his devil and that it can only be vanquished through laughter. In this explication, I will show that Nietzsche uses intertextual allusion to place this laughter that destroys the spirit of gravity in relation to the words of the character Clytemnestra in Aeschylus' Agamemnon. I will also show that Nietzsche binds this allusion to aphoristic text, thus framing aphorism as a multivalent form of writing that destroys absolute, …

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).

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, …

Fruit And Vegetable Resource Maps: Mapping Fruit And Vegetable Waste Through The Wholesale Supply Chain, Leon A. Terry, Carlos Mena, Adrian Williams, Nigel Jenney, Peter Whitehead

Business Faculty Publications and Presentations

Research by WRAP has shown that households waste around three million tonnes of fruit and vegetables per year, raising concerns about the economic and environmental impacts of food waste. This study has been conducted to quantify the level of loss and waste of fruit and vegetables before they reach consumers, through the retail and wholesale supply chain. Furthermore, the study determined how, where and why the product was wasted.

Eleven fresh produce types were selected based on their consumption, post-harvest physiology and management. The 11 products chosen were strawberries, raspberries, tomatoes, lettuce, apples, onions, potatoes, brassicas, citrus, avocados and bananas; …
