Critical Arts-Based Projects For Equitable Emergent Teacher Education Researcher Preparation, Lauren Jaramillo, Marcus North, Christian Valdez, Camea Davis, Luiz Claudio Barcellos

Northwest Journal of Teacher Education

This paper captures how four BIPOC student researchers and their Black woman professor used critical arts-based research methods to resist the policies and systems predisposed to BIPOC’s dispossession in academia. The arts utilized for our purpose were: songwriting, art collage, theater, and podcast. We determined these methods to be in tune with our researcher selves, which allowed for a more equitable approach preparing teacher education researchers. This work has implications for teacher educators, graduate research programs, and graduate students.

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.

Pandemic As Portal: Disrupting The Violence Of Epistemicide In Teacher Education, Ramon Vasquez

Northwest Journal of Teacher Education

Epistemicide involves more than just the accidental displacement of different knowledges. By its very nature, epistemicide involves the intentional silencing, devaluing, and violent destruction of knowledge systems (Mignolo, 2007). While much has been written about radically altering education by including other knowledge in schools, what this entails within the context of teacher education methods courses, particularly during the pandemic, has received less attention. This paper examines and discusses what creating another teacher education might involve by probing some of the spaces and openings for epistemic disobedience exposed and made visible during the pandemic. My conceptualization of another teacher education simultaneously …

Who Lives, Who Dies, Who Sings Which Story?: Narrative Production And Race In The Curriculum Of Film Musicals, Joanna Batt, Michael Joseph

Northwest Journal of Teacher Education

Film musicals serve as a tool to infuse historical and cultural content into social studies curricula towards greater student engagement—for example, Lin Manuel-Miranda's Hamilton has become a celebrated classroom piece due to its ability to blend history with hip-hop and pop culture. Yet beyond language and content scans, teachers rarely examine or utilize musicals for how their narratives (mis)represent racial communities. This critical film analysis of three film musicals, using the theoretical framework of history production, reveals themes of historical morality, romantic relationship and race, and implicit/explicit racial messaging. Although troubling in their overall contribution to racial projects, film musicals …

Preservice Teachers And Curricular Matters: A Reflection On Field Sites As Transformative Spaces, Annmarie Dull, Elizabeth Chase

Northwest Journal of Teacher Education

Field experiences are essential to teacher preparation and education, and they are enriched by strong community partnerships where preservice teachers build knowledge from mentor teachers, families, students, and other stakeholders. The influence that the neoliberal agenda has on education forces preservice teachers and the preparation programs they attend to make difficult decisions about creating and sustaining these field experiences. In this paper, we call attention to the difficulties preservice teachers—and the preparation programs they attend—face when seeking to challenge social injustice and curriculum epistemicide. In so doing, we end with ideas for future consideration and scholarly inquiry.

Applying Biomimetic Passive Dynamics To A Quadruped Robot Leg, Emma Krnacik

Dissertations and Theses

The study of synthetic nervous systems is an emerging field within biomimetic robotics as an alternative to more classic control techniques. As the modeling of these nervous systems becomes more accurate, it is important to note that the nervous system and physical system co-evolved and continue to operate in an interdependent fashion. Many legged robots, including the existing quadruped in the AARL, have leg systems that may have similar geometrical properties to that of a mammal, but have significantly different dynamic properties. This paper presents a method for designing a limb so that the passive dynamics more accurately represent that …

The Effects Of Online Learning Experience During The Covid-19 Pandemic On Students’ Satisfaction, Adjustment, Performance, And Loyalty, Michal Wilczewski, Oleg Gorbaniuk, Terry Mughan, Ewelina Wilczewska

Business Faculty Publications and Presentations

This research investigates the student online learning experience (SOLE) during the 2020 spring Covid-19 pandemic. We collected quantitative data through an online survey from 362 international and 488 domestic students at a large Polish University. Correlation and path analysis within a conceptual model of SOLE and its academic outcomes established that (1) SOLE explained adjustment, performance, satisfaction, and loyalty, (2) academic adjustment predicts performance, satisfaction, and loyalty, (3) that academic performance and satisfaction predict student loyalty, and (4) that academic performance predicts satisfaction. Interestingly, time spent in quarantine/self-isolation did not exert any effect on academic outcomes in SOLE. Moreover, qualitative …

Response Of Soil Respiration To Changes In Soil Temperature And Water Table Level In Drained And Restored Peatlands Of The Southeastern United States, E. E. Swails, K. Krauss, Marcelo Ardón, A. L. Peralta, A. M. Helton, Jennifer L. Morse, Multiple Additional Authors

Environmental Science and Management Faculty Publications and Presentations

Background

Extensive drainage of peatlands in the southeastern United States coastal plain for the purposes of agriculture and timber harvesting has led to large releases of soil carbon as carbon dioxide (CO2) due to enhanced peat decomposition. Growth in mechanisms that provide financial incentives for reducing emissions from land use and land-use change could increase funding for hydrological restoration that reduces peat CO2 emissions from these ecosystems. Measuring soil respiration and physical drivers across a range of site characteristics and land use histories is valuable for understanding how CO2 emissions from peat decomposition may respond to raising water table levels. …

Moving From Probabilistic To Time-Based On-Time Performance (For Practitioners), Miles James Allen Crumley

PSU Transportation Seminars

On-Time Performance (OTP) is a probabilistic measure that tells the customer the likelihood that the trip they are about to take will arrive "on-time." However, this metric forces the customer to think in terms of a probability of trip timeliness and not an actual time value for how timely the trip will be. This presentation will explore a new way to examine on-time performance by quantifying the timeliness of trips. Customers can then use this information to determine which trip would be the best to take based on when they need to arrive at their destination. Using a system science …

Remote Sensing Evidence For Significant Variations In The Global Gross Domestic Product During The Covid-19 Epidemic, Bin Guo, Wencai Zhang, Lin Pei, Xiaowei Zhu, Pingping Luo, Weili Duan

Mechanical and Materials Engineering Faculty Publications and Presentations

Coronavirus disease 2019 (COVID-19) has been spreading rapidly and is still threatening human health currently. A series of measures for restraining epidemic spreading has been adopted throughout the world, which seriously impacted the gross domestic product (GDP) globally. However, details of the changes in the GDP and its spatial heterogeneity characteristics on a fine scale worldwide during the pandemic are still uncertain. We designed a novel scheme to simulate a 0.1° × 0.1° resolution grid global GDP map during the COVID-19 pandemic. Simulated nighttime-light remotely sensed data (SNTL) was forecasted via a GM(1, 1) model under the assumption that there …

Urban Nesting Biology, Population Viability And Ecology Of The Willow Flycatcher, Empidonax Traillii, Stephanie Alexandra Byrne Doorly

Dissertations and Theses

Reproductive success, in any species, relies both on the habitat utilized to reproduce and on the successful reproductive output of individual animals within a population. Populations in turn rely on the reproductive fitness of the individual. Whether populations remain stable, grow, or decline ultimately relies on the combined reproductive output of the individuals within that population.

We studied the Willow Flycatcher (Empidonax traillii; henceforth WIFL), a well-studied Neartic-Neotropical migrant passerine whose breeding range extends from the east to west coast of North America. Across much of their range, and in particular in the western regions, breeding population are …

Securing Humane Values At Yale, Bennett B. Gilbert

University Studies Faculty Publications and Presentations

For four days in the first week of November, the Yale administration closed the Schwarzman Center and the Good Life Center in the Schwarzman Center to celebrate Stephen Schwarzman and his donation to renovate the building he wanted named after himself. The Commons at the Schwarzman Center used to be called University Commons, a name that indicated its place at the center of Yale life as common ground. As he did in giving money for the renovation of the New York Public Library, when he insisted that his name be carved on its stone entrance beneath the names of the …

The Age Of Planetary Revolution: Remembering The Future In Science Fiction, Carl Abbott

Urban Studies and Planning Faculty Publications and Presentations

In lieu of an abstract, a short excerpt:
The year is 2350. The solar system maintains a fragile political balance, with Earth’s Martian colony now an independent republic locked in an armed standoff with its former overlord. The scattered mining settlements of the asteroid belt are still struggling under the thumbs of both inner planets. This is the starting point for The Expanse (2011–22), a series of novels (and now a TV show) by Daniel Abraham and Ty Franck, writing together as James S. A. Corey. It is also part of a long-standing science fiction tradition in which writers have …

Review Essay: Recent Works In The Political Theory Of Migration, Alexander Sager

Philosophy Faculty Publications and Presentations

Thirty-five years ago, Joseph Carens published “Aliens and Citizens: The Case for Open Borders” in the Review of Politics. It is only a slight overstatement to say that this article created the subfield of political theory of migration. Today, the field is flourishing. Migration continues to be one of today's most politically fraught and morally urgent issues. An estimated hundred million people have fled violence and persecution. Hundreds of millions more cross international borders every year. States have responded with highly restrictive policies, in which people need to resort to perilous routes, often in the hands of smugglers, to …

Explaining Backlash: Social Hierarchy And Men’S Rejection Of Women’S Rights Reforms, Lindsay J. Benstead, Ragnhild L. Muriaas, Vibeke Wang

Political Science Faculty Publications and Presentations

Governments promote gender-sensitive policies, yet little is known about why reform campaigns evoke backlash. Drawing on social position theory, we test whether marginalized (women’s organizations) or intrusive (Western donors) messengers cause resistance across public rights (quotas) and private rights (land reform). Using a framing experiment implemented among 1,704 Malawians, we find that females’ attitudes are unaffected by campaigns, while backlash occurs among patrilineal and matrilineal males. Backlash among men is more common for sensitive private rights (land reform) than public rights (quotas) and Western donors than women’s organizations, suggesting complex effects generally more consistent with the intrusiveness hypothesis.

Critical Awareness, Reflection, And Action In Head Start Leadership: A Critical Consciousness Case Study Of Head Start Leaders, Christopher Pearce Agudelo

Dissertations and Theses

Diverse families with preschool-aged children are at an enhanced risk of marginalization in the United States. Whether they are of a different race, level of ability, gender, or socioeconomic background, they need early childhood leaders and educators who can focus on caring for their children. In this exploratory qualitative study, I conducted five open-ended interviews with Head Start education managers--a similar position to a preschool Director or a K-12 Principal. The objective was to understand better how Head Start Education Managers attend to equity and inclusion via critical awareness, critical reflection, and critical action. I utilized the three-element construct of …

System-Level Risk Management Of Transportation Structures And Networks, David Y. Yang

PSU Transportation Seminars

Conventional risk assessment approaches in infrastructure management do not fully capture the system-level impact of structural failure or service disruption. As a result, the priorities of preservation projects may be misidentified, leading to suboptimal maintenance schedules and waste of resources. In this presentation, we will first illustrate why conventional risk assessment is not suitable for transportation structures and networks due to interdependency between assets, and then demonstrate how system-level preservation policies can be devised using novel algorithms adapted from the field of deep reinforcement learning. Results from a series of case studies showcase that the system-level risk management is essential …

Quantum Key-Length Extension, Joseph Jaeger, Fang Song, Stefano Tessaro

Computer Science Faculty Publications and Presentations

Should quantum computers become available, they will reduce the effective key length of basic secret-key primitives, such as blockciphers. To address this we will either need to use blockciphers with inherently longer keys or develop key-length extension techniques to amplify the security of a blockcipher to use longer keys.

We consider the latter approach and revisit the FX and double encryption constructions. Classically, FX was proven to be a secure key-length extension technique, while double encryption fails to be more secure than single encryption due to a meet-in-the-middle attack. In this work we provide positive results, with concrete and tight …

Pile-Supported Wharves Subjected To Inertial Loads And Lateral Ground Deformations. Ii: Guidelines For Equivalent Static Analysis, Milad Souri, Arash Khosravifar, Stephen E. Dickenson, Scott Schlechter, Nason Mccullough

Civil and Environmental Engineering Faculty Publications and Presentations

An equivalent static analysis (ESA) procedure is proposed for the design of pile-supported wharves subjected to combined inertial and kinematic loads during earthquakes. The accuracy of the ESA procedure was evaluated against measurements from five large-scale centrifuge tests. The wharf structures in these tests were subjected to a suite of recorded ground motions and the associated superstructure inertia, as well as earthquake-induced slope deformations of varying magnitudes. It is shown that large bending moments at depths greater than 10 pile diameters were primarily induced by kinematic demands and can be estimated by applying soil displacements only (i.e., 100% kinematic). In …

Pile-Supported Wharves Subjected To Inertial Loads And Lateral Ground Deformations. I: Experimental Results From Centrifuge Tests, Milad Souri, Arash Khosravifar, Stephen E. Dickenson, Scott Schlechter, Nason Mccullough

Civil and Environmental Engineering Faculty Publications and Presentations

Five dynamic, large-scale centrifuge tests on pile-supported wharves were used to investigate the time- and depth-dependent nature of kinematic and inertial demands on the deep foundations during earthquake loading. The wharf structures in the physical experiments were subjected to a suite of recorded ground motions and imposed superstructure inertial demands on the piles. Partial to full liquefaction in loose sand resulted in slope deformations of varying magnitudes that imposed kinematic demands on the piles. It was found that the wharf inertia and soil displacements were always in phase during the critical cycle when bending moments were at their maximum values. …

The Consequential Role Of Aesthetics In Forest Fuels Reduction Propensities: Diverse Landowners’ Attitudes And Responses To Project Types, Risks, Costs, And Habitat Benefits, Robert G. Ribe, Max Nielsen-Pincus, Chris Enright, Bart R. Johnson, David Hulse

Environmental Science and Management Faculty Publications and Presentations

Private landowners in the southern Willamette Valley of Oregon, USA were surveyed. The survey queried probabilities of implementing specific fuels reduction projects in extensive areas of specific forest types on their property. The projects were described in relation to the beginning and target forest types, the actions required, costs, and long-term maintenance. Forest types were first rated for scenic beauty and informed levels of wildfire risk reduction, scarce habitat production, and associated property rights risks. Propensities to perform each fuels reduction project were then obtained. These were adversely affected by disbelief in heightened wildfire risks or climate change, higher project …
