Learning To Teach About Climate Justice And Social Justice In Science Methods, Mindy J. Chappell
Learning To Teach About Climate Justice And Social Justice In Science Methods, Mindy J. Chappell
Northwest Journal of Teacher Education
In November, the Editors of NWJTE sat down for a conversation with Dr. Mindy J. Chappell, a Science Teacher Educator in the College of Education at Portland State University. Dr. Chappell’s passions include developing teachers who are prepared to disrupt normative science ideologies and provide young people with science instruction that encourages and empowers them to be leaders in their communities. She engages in arts-based educational science research through the methodology of Ethnodance (a term she coined). She places young people and their lived experiences at the heart of her work.
Feminist Political Ecology In The Classroom, Ella J. Yeigh
Feminist Political Ecology In The Classroom, Ella J. Yeigh
Northwest Journal of Teacher Education
As the effects of climate change are being felt more frequently, discussions on how to combat such a massive issue are increasingly prevalent. Finding solutions to the climate crisis requires an understanding of how mainstream economic systems have led to the climate crisis and using these same principles to get out of the climate crisis is misguided. Economic actions have inherent value biases that have real political effects. Feminist Political Ecology (FPE) as a theoretical model presents a better understanding of how values that are inherent in economic models such as reliance on efficiency, markets, and continual economic growth have …
The Negative Stigma Surrounding Mathematics, Marissa A. Greisen
The Negative Stigma Surrounding Mathematics, Marissa A. Greisen
PSU McNair Scholars Online Journal
There is a negative stigma that surrounds mathematics in our education system. It is important to bring notice to this for the benefit of future students. There is a lot of research claiming that math is looked down on, but they do not answer why, or what we can do to fix it. Why is there a greater negative stigma around math and not other subjects? What roles to teachers, parents, and peers play in this stigma? In this article, I created a survey for people to answer questions regarding their opinion on math, who they believe typically does well …
Climate Change Curricula In Alberta, Canada: An Intersectional Framing Analysis, Greg Lowan-Trudeau
Climate Change Curricula In Alberta, Canada: An Intersectional Framing Analysis, Greg Lowan-Trudeau
Northwest Journal of Teacher Education
This article is comprised of a climate change-focused framing analysis of proposed revisions to Alberta, Canada’s K-6 curriculum as an ideologically motivated manifestation of curricular epistemicide. Eisner’s three curricula—the explicit, implicit, and null—and scholarship related to intersectional climate and environmental justice, education, and communication provide the theoretical framework. This inquiry concludes with a critical discussion of and possible alternatives to the revised curriculum with further consideration of the implications for those involved with similar endeavours in other jurisdictions across Canada and around the world.
Reviving Knowledges Through Play And Resistance: The Case Of Navajo Conceptions Of Space, Daniel Ness, Richard D. Sawyer
Reviving Knowledges Through Play And Resistance: The Case Of Navajo Conceptions Of Space, Daniel Ness, Richard D. Sawyer
Northwest Journal of Teacher Education
The authors explore a possible cause of epistemicidal predispositions of the dominant Eurocentric curricula. They posit that one way to determine a plausible contributing factor of this increasing devastation is to consider epistemicide through the lens of intellectual development. To do this, the authors examine parallel patterns of behavior in the domains of developmental and cognitive psychology. The authors then discuss an alternative framework to the Western conception of space within formal K-12 education by presenting the Navajo conception of space and play. Throughout the paper, the authors argue that all students—and especially those living in poverty in commercially constructed, …
Mathematics In The Woods: Exploring Low-Income Parents’ Perceptions Of And Involvement In Their Children’S Mathematical Learning, Lulu Sun
Northwest Journal of Teacher Education
This article features data from a three-day mathematics camping trip that offered parents and their children time and space to enjoy non-digital activities and mathematics-building tasks. Drawing upon data from a larger qualitative study of children and their parents, this article specifically focuses on 10 parents’ perceptions of their children’s mathematics learning, problem-solving, and wellbeing. Findings suggest that, although parents are interested in their children’s mathematics learning, they are most concerned with their children’s development of problem-solving abilities and social skills. Moreover, students’ own learning experience is important for their mathematics learning.
An Analysis Of The Reactivation Potential Of A Deep-Seated Landslide In The Oregon Coast Range Under Varying Hydrologic Conditions With Seismic Triggering, Emily E. Smoot
Anthós
Landslides can occur in many locations across the world and have the potential to be extremely destructive if failures occur near populated areas. Failures are most likely to occur on slopes that have already experienced numerous failures. This means they are a considerable hazard, and the risk involved with building in areas that have previously experienced landslides should be adequately understood. This study examines the reactivation potential of a deep-seated landslide located in the Oregon Coast Range. The analysis of this landslide included creating a map of the surface morphology and computing the factor of safety for the deposit using …
The Energy Policy Act Of 2005: The Rapid Decline Of Jura Majestatis For Communities In Ohio, Alexander Krokus
The Energy Policy Act Of 2005: The Rapid Decline Of Jura Majestatis For Communities In Ohio, Alexander Krokus
Hatfield Graduate Journal of Public Affairs
Since Nobel Prize recipient Svante Arrhenius realized that fossil fuel combustion increased CO2 emissions in our atmosphere in 1896, scientists and policy makers have acknowledged the calamitous potential for the oil and gas industry to render substantial deleterious effects on ecosystems. Yet in 2016, the U.S. utilized fossil fuels to facilitate 80.9% of all energy consumption.1 Subsequent to the passage of the Energy Policy Act of 2005, the Federal Energy Regulatory Commission vastly encouraged outside economic investment into our oil and gas infrastructure. Natural resources situated in geologic formations that possess low permeability, which were once considered previously inaccessible …
The Hidden Killer: Towards Regulating Railyard Diesel Particulate Matter Emissions In Oregon, Kevin Downing, Robert Mccullough, Eric Shierman
The Hidden Killer: Towards Regulating Railyard Diesel Particulate Matter Emissions In Oregon, Kevin Downing, Robert Mccullough, Eric Shierman
Hatfield Graduate Journal of Public Affairs
Diesel engines are the predominant choice when moving freight, particularly for the railroad industry. Compared to gasoline engines, diesel emits relatively few of the toxic compounds generally associated with internal combustion. However, diesel engines produce a disproportionate quantity of particulate aerosols. Airborne pollutants from locomotives and freight transferring equipment in railyards significantly impact the air quality of surrounding neighborhoods. We summarize the health impacts of diesel particulates emitted from railyards in Oregon. Using the most conservative range of the EPA's assessment, we calculate a Pigouvian Tax for the railroad companies to pay, totaling $624.24 per μg/m3 for each person in …
Re-Imagining Regulatory Approaches For Methane Emissions, Jongeun You
Re-Imagining Regulatory Approaches For Methane Emissions, Jongeun You
Hatfield Graduate Journal of Public Affairs
Recently, the U.S. Environmental Protection Agency (EPA) took a step-back in regulating the methane released during natural gas extraction. In June 2016, the EPA issued the first federal regulations on methane, estimating methane emissions would decrease by a total of 510,000 short tons in 2025, with a potential net benefit of $160 million. Yet, in October 2018, the EPA released a new proposal that weakened the 2016 methane rules, estimating methane emissions would increase by a total of 380,000 short tons in 2025, with a potential saving of $484 million. This paper explores the EPA’s drastic change between 2016 and …
A Network Approach To Complex Problems: Understanding Collaborative Governance In Watershed Management, Allison Daniel
A Network Approach To Complex Problems: Understanding Collaborative Governance In Watershed Management, Allison Daniel
Hatfield Graduate Journal of Public Affairs
The complexity of current environmental problems poses a challenge to the field of public management. With multiple stressors acting on the earth’s natural systems, the likelihood that complex environmental problems will persist is undeniable. Traditional approaches to such problems follow a top-down method, often useful for problem management within public policy; however, it proves too rigid when considering the complexity of environmental policy. Recent literature points to the use of collaboration and coordination in addressing complex problems, whereby stakeholders accumulate knowledge and resources across a variety of fields. One such method is network governance, identified as a problem-solving approach capable …
Advancing Rationality With Sustainability: An Analysis Of Agent-Based Simulation, Osman Goktug Tanrikulu
Advancing Rationality With Sustainability: An Analysis Of Agent-Based Simulation, Osman Goktug Tanrikulu
Hatfield Graduate Journal of Public Affairs
Today, falling trends of species and ecosystem in the world due to overconsumption and destruction of natural resources are at critical levels. It is vital for humanity to operate with sustainable and resilient modes of production and consumption. In this regard, this paper examines the basic premise of rationality and introduces sustainability as an advancement to the theoretical concept of rationality. Thus, a rational mindset and a sustainable mindset are compared under depletion of environmental resources. The understanding of rationality in the analysis is based on Garett Hardin’s (1968) ‘the tragedy of the commons’ model, in which actors are self-interested …
Trajectory Analysis Of Black Carbon In The Arctic Region, Kimberly Gottschalk
Trajectory Analysis Of Black Carbon In The Arctic Region, Kimberly Gottschalk
PSU McNair Scholars Online Journal
Black carbon (BC) is a troubling particulate. Commonly known as soot, BC forms through the incomplete combustion of fossil fuels, biofuels, and biomass. It has a very low albedo compared to natural particulates making it a very efficient absorber of solar radiation. As BC is deposited on snow and ice, albedo is decreased - enhancing solar heating and increasing meltwater production. With rising air temperatures, melting rates of polar ice are increasing and are being enhanced by BC, leading to accelerated global sea level rise.
This study aimed to document sources and deposition areas of BC in the Arctic. Utilizing …

Open-Access Crystallography Database Administration: Preparation And Upload Of 400 Structures, Justin Shuck
PSU McNair Scholars Online Journal
Since 2004, Portland State's Nano-Crystallography Group has provided crystallographic resources including five interactive open-access databases (educational subset of the Crystallographic Open Database (COD), Crystal Morphology Database, Nano-Crystallography Database and Wiki Crystallography Database) as well as a mirror to the whole COD, which is the world's largest openaccess crystallography database (with currently over 235 thousand data entries of inorganic, organic, and metal-organic compounds as well as minerals). Before information can be stored inside of databases they must be put in Crystallographic Information Framework files (CIFs), the framework established by the International Union of Crystallography, and the worldwide standard for representing crystallographic …
An Analysis Of The Impact Of Global Warming On Hurricane Activity In The United States, Jesse Senzer
An Analysis Of The Impact Of Global Warming On Hurricane Activity In The United States, Jesse Senzer
Anthós
This paper discusses the influence of global warming on ocean temperatures, and explains how vertical wind shear affects hurricane formation. It explores the scientific arguments against linking global warming to increased hurricanes, that ocean warming increases vertical wind shear in the main development region for Atlantic hurricanes, and that current/recent American hurricane trends fall within the realm of natural, multidecadal oscillations. Arguments supporting the link between global warming and hurricanes are addressed with climate modeling that links sea surface temperature (SST) increase to anthropogenic causes. It discusses SST’s influencing hurricane activity globally, if not locally to the U.S., and points …

LIDAR and topographic data were used to identify areas of high landslide susceptibility. An arctangent equation was used to calculate slope angle, design criteria of susceptibility and designate zones of high, moderate, and low risk.
Embedding Parallel Computation In A Stochastic Mesh Network: A Morphogenetic Approach, Max Orhai
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 …
