The Adolescent Behavioral Index: Identifying Students At Risk For Disengagement In High School, Graham G. Rifenbark, Allison Lombardi, Jennifer Freeman, Mary Morningstar

Special Education Faculty Publications and Presentations

In this study, we examined the relationship between self-reported adolescent perceptions of school climate and extant high school academic and behavioral data; specifically grade point average, attendance, tardies, and office discipline referrals, using a Multiple Indicators Multiple Causes (MIMIC) model on a sample of high school students (n = 5039) with and without disabilities. Findings show evidence of a robust Adolescent Behavioral Index when controlled for disability status as those with disabilities are expected to have lower index scores. Implications for research and practice are focused on the Adolescent Behavioral Index as a mechanism for systematic data collection that may …

A Comparative Study Of Online Art History Information Literacy Instruction: A Tale Of Two Platforms, Elsa Loftis

Library Faculty and Staff Publications and Presentations

In a collaborative effort between three departments at Portland State University, investigators designed and created Information Literacy (IL) modules tailored to the needs of Art History students utilizing two delivery platforms. One platform employed adaptive software (in this study, the product is called Realizeit), and the other was a static environment called Pressbooks. Students were randomly divided into cohorts based on these delivery methods. The author compared results of pre and post information literacy assessments and completed an analysis of students’ preliminary bibliographies to measure the success of the IL instruction. But the core investigation was to determine whether the …

Carli Creek Regional Water Quality Project: Assessing Water Quality Improvement At An Urban Stormwater Constructed Wetland, Christopher L. Desiderati

Environmental Science and Management Professional Master's Project Reports

Stormwater management is an ongoing challenge in the United States and the world at-large. As state and municipal agencies grapple with conflicting interests like encouraging land development, complying with permits to control stormwater discharges, “urban stream syndrome” effects, and charges to steward natural resources for the long-term, some agencies may turn to constructed wetlands (CWs) as aesthetically pleasing and functional natural analogs for attenuating pollution delivered by stormwater runoff to rivers and streams. Constructed wetlands retain pollutants via common physical, physicochemical, and biological principles such as settling, adsorption, or plant and algae uptake. The efficacy of constructed wetlands for pollutant …

2022 Zero Suicide Implementation In Oregon: Cross‐Site Follow‐Up Change Report, Karen Cellarius, Aliza Tuttle

Regional Research Institute for Human Services

This implementation self‐assessment and the accompanying web survey were adapted for the Oregon Health Authority (OHA) by Portland State University in collaboration with the OHA Youth Suicide Prevention staff. The assessment was adapted from three existing Zero Suicide resources available at http://zerosuicide.org/.

The Organizational Self‐Study is a questionnaire about the extent to which each component of the Zero Suicide approach is in place at a single organization. Zero Suicide recommends completing this self‐study at the start of an organization’s Zero Suicide initiative, then every 12 months after that as a measure of fidelity to the model. The self‐study questions …

Does Recreational Marijuana Dispensing Induce Substitution For Alcohol?, Aubrey E. Mange

Economics Masters Project Research Papers

I exploit geographic and temporal variation in recreational marijuana dispensing to estimate its effect on alcohol related prices and mortalities. I interpret the finding of a casual reduction in alcoholic poisonings as evidence for a substitutive relationship, contributing to a growing marijuana policy literature and the divided economic literature exploring substitution between the two goods.

Music: Modernist Remediation And Technologies Of Listening, Josh Epstein

English Faculty Publications and Presentations

Excerpt:
Ludwig van Beethoven, if not exactly a modernist, offers ample fodder for modern artists looking to defend – or expand – their turf. While producing City Lights (1928), Charlie Chaplin responded to the newly popular ‘talkies’ by proclaiming that ‘Moving pictures need sound as much as Beethoven symphonies need lyrics’ (qtd. in Crafton 1999: 296).

Species-Specific Interactions In Avian–Bryophyte Dispersal Networks, Matthew Chmielewski, Sarah Eppley

Biology Faculty Publications and Presentations

Studies from seed plants have shown that animal dispersal fundamentally alters the success of plant dispersal, shaping community composition through time. Our understanding of this phenomenon in spore plants is comparatively limited. Though little is known about species-specific dispersal relationships between passerine birds and bryophytes, birds are particularly attractive as a potential bryophyte dispersal vector given their highly vagile nature as well as their association with bryophytes when foraging and building nests. We captured birds in Gifford Pinchot National Forest to sample their legs and tails for bryophyte propagules. We found 24 bryophyte species across 34 bird species. We examined …

Phylogenetics And Genetic Variation Of Heligmosomoides Thomomyos In Western Pocket Gophers (Thomomys Spp.), Malorri R. Hughes, Alexandra A. Gibson, Emily R. Wolfe, Cecily D. Bronson, Deborah A. Duffield

Biology Faculty Publications and Presentations

The host specificities and systematics of North American Heligmosomoides species remain particularly uncertain. The primary aim of this study was to verify that a species described previously based only on morphology, H. thomomyos, from pocket gopher (Rodentia: Geomyidae) hosts in Oregon represented a monophyletic lineage. In order to address this aspect, as well as to further understand relationships and geographic patterns, we carried out phylogenetic, genetic diversity, and population dynamic analyses using partial 18S rRNA and COI mtDNA sequences of Heligmosomoides specimens. Phylogenetic analyses suggested that there are likely multiple Heligmosomoides species present in these hosts. This was supported by …

Gendered Self-Views Across 62 Countries: A Test Of Competing Models, Natasza Kosakowska-Berezecka, Jennifer K. Bosson, Pawel Jurek, Eric Mankowski, Multiple Additional Authors

Psychology Faculty Publications and Presentations

Social role theory posits that binary gender gaps in agency and communion should be larger in less egalitarian countries, reflecting these countries’ more pronounced sex-based power divisions. Conversely, evolutionary and self-construal theorists suggest that gender gaps in agency and communion should be larger in more egalitarian countries, reflecting the greater autonomy support and flexible self-construction processes present in these countries. Using data from 62 countries (N = 28,640), we examine binary gender gaps in agentic and communal self-views as a function of country-level objective gender equality (the Global Gender Gap Index) and subjective distributions of social power (the Power …

Changes To California Alfalfa Production And Perceptions During The 2011-2017 Drought, Alida A. Cantor, Bethani Turley, Charles Cody Ross, Mathern Glass

Geography Faculty Publications and Presentations

California experienced a severe multiyear drought stretching from 2011 through 2017, significantly reducing surface water supply for ecosystems, agriculture, and humans and prompting coordinated conservation efforts. Given that agriculture is the largest consumptive use of water in the state, one anticipated response to a severe drought would be to decrease production of low-value, high-water-use crops such as alfalfa. In this article we use a multimethod approach to examine both spatial distribution and public perceptions of alfalfa production in California over the course of the 2011 through 2017 drought. We find that although California alfalfa production did decline at the state …

This edited volume advances our understanding of climate relocation (or planned retreat), an emerging topic in the fields of climate adaptation and hazard risk, and provides a platform for alternative voices and views on the subject. As the effects of climate change become more severe and widespread, there is a growing conversation about when, where and how people will move. Climate relocation is a controversial adaptation strategy, yet the process can also offer opportunity and hope. This collection grapples with the environmental and social justice dimensions from multiple perspectives, with cases drawn from Africa, Asia, Australia, Oceania, South …

Colonial Necrocapitalism, State Secrecy, And The Palestinian Freedom Tunnel, Nadera Shalhoub-Kevorkian, Stephanie Wahab

School of Social Work Faculty Publications and Presentations

Secrecy and the use of “secret information” as capital in the hands of the state is mobilised by affective racialised machineries, cultivated on “security” grounds. Securitised secrecy is an assemblage of concealed operations juxtaposing various forms of invasions and dispossessions. It is a central strategy in the politico-economic life of the state to increase its scope of domination. Secrecy is used and abused to entrap and penetrate political subjects and entities. This article explores the necrocapitalist utilisation of secrecy embedded in the coloniser’s attempt to distort the mind of the colonised. Built from the voices of those affected by secrecy’s …

We aggregated response rankings to identify salient influences, motivations, and …

Mass Timber Building Life Cycle Assessment Methodology For The U.S. Regional Case Studies, Hongmei Gu, Shaobo Liang, Francesca Pierobon, Maureen Puettmann, Indroneil Ganguly, Cindy Chen, Rachel Pasternack, Mark Wishnie, Susan Jones, Ian Maples

Publications, Reports and Presentations

The building industry currently consumes over a third of energy produced and emits 39% of greenhouse gases globally produced by human activities. The manufacturing of building materials and the construction of buildings make up 11% of those emissions within the sector. Whole-building life-cycle assessment is a holistic and scientific tool to assess multiple environmental impacts with internationally accepted inventory databases. A comparison of the building lifecycle assessment results would help to select materials and designs to reduce total environmental impacts at the early planning stage for architects and developers, and to revise the building code to improve environmental performance. The …

Comparative Lcas Of Conventional And Mass Timber Buildings In Regions With Potential For Mass Timber Penetration, Maureen Puettmann, Francesca Pierobon, Indroneil Ganguly, Hongmei Gu, Cindy Chen, Shaobo Liang, Susan Jones, Ian Maples, Mark Wishnie

Publications, Reports and Presentations

Manufacturing of building materials and construction of buildings make up 11% of the global greenhouse gas emission by sector. Mass timber construction has the potential to reduce greenhouse gas emissions by moving wood into buildings with designs that have traditionally been dominated by steel and concrete. The environmental impacts of mass timber buildings were compared against those of functionally equivalent conventional buildings. Three pairs of buildings were designed for the Pacific Northwest, Northeast and Southeast regions in the United States to conform to mass timber building types with 8, 12, or 18 stories. Conventional buildings constructed with concrete and steel …

Nature-Based Solutions In Environmental Planning: Ecosystem-Based Adaptations, Green Infrastructures, And Ecosystem Services To Promote Diversity In Urban Landscapes, Lorena Alves Carvalho Nascimento

Dissertations and Theses

Nature-based solutions encompass strategies that explore ecosystem-based adaptations, green infrastructures, and ecosystem services in environmental planning and landscape management. However, nature-based solutions do not always consider ecological values and perspectives from Black, Indigenous, and Global South population. This dissertation has three independent papers that explore the application of ecosystem-based adaptations, green infrastructures, and ecosystem services in communities unheard by environmental planning agencies. The first paper is a conceptual framework that used literature review and observations of current human-nature interactions to reflect how the criminalization, acculturation, and cultural appropriation of cultural ecosystem services have burdened Black and Indigenous identities. Recommendations for …

Ecological Exposure And Effects Of Microplastics In Crabs Along The Pacific Coast, Dorothy A. Horn

Dissertations and Theses

Microplastics have been documented across the global oceans as an ubiquitous pollutant. Found in the water column, sediment, shorelines, estuaries, freshwater streams and rivers along with terrestrial soils, flora and fauna. The continuous input of plastic waste into the marine environment doesn't seem to be slowing as the amount of plastic created each year increases globally.

This study investigated (1) the effects of microplastic ingestion in the indicator species, the Pacific mole crab (Emerita analoga), testing the predator avoidance behavior, reproductive output and parasitism effects when an adult female gravid crab had ingested microplastics (2) adult mortality, hatching …

Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys

Dissertations and Theses

Antipsychotic medication use (APU) in assisted living and residential care (AL/RC) settings is an under-studied and controversial health policy issue. APU in older adults with dementia is associated with an increased risk of falls, hospitalizations, and early mortality. I operationalize the Institutional Analysis and Development Framework using a situational analysis approach, an extension of grounded theory methods, to explore the APU in Oregon AL/RC settings. Regulatory deficiency citations, Oregon AL/RC population data, and semi-structured interviews suggest that staff role clarity, organizational characteristics, and perceived agency influence decision-making around APU. AL/RC providers and caregivers are forced to simultaneously balance and prioritize …

Emotional Intelligence And Resonant Leadership: Investigating School Principals' Preparation And Professional Development In Response To Covid-19 And Other Challenges, Ashlie Kaye Miller

Dissertations and Theses

Research has shown that high levels of emotional intelligence and resonant leadership can reduce workplace stress and increase the health, wellness, satisfaction, and performance of employees. Many K-12 principals face a myriad of challenges that tend to produce chronic stress, including the recent Covid-19 pandemic. Yet, it is unclear how the preparation and professional development (PPD) programs available to principals incorporate and encourage resonant leadership practices that are needed to effectively cope with these challenges. This study used an explanatory sequential mixed methods design to examine the perceptions of K-12 principals in Oregon regarding: (a) their needs and challenges, especially …

Modifying The Aspect Survey To Support The Validity Of Student Perception Data From Different Active Learning Environments, Nicole Naibert, Erin E. Shortlidge, Jack Barbera

Chemistry Faculty Publications and Presentations

Measuring students’ perceptions of active learning activities may provide valuable insight into their engagement and subsequent performance outcomes. A recently published measure, the Assessing Student Engagement in Class Tool (ASPECT), was developed to assess student perceptions of various active learning environments. As such, we sought to use this measure in our courses to assess the students’ perceptions of different active learning environments. Initial results analyzed with confirmatory factor analysis (CFA) indicated that the ASPECT did not function as expected in our active learning environments. Therefore, before administration within an introductory biology course that incorporated two types of active learning strategies, …

Working Paper No. 57, The Plight Of The Indigenous In British North America, Maria Nicolas-Reyes

Working Papers in Economics

This inquiry seeks to establish that the Indigenous population of North America experienced a tragic fate as a result of British colonization and American dominance. Upon the arrival of the English colonists, infectious diseases spread rapidly, disrupting Native American’s way of life and also decimating their populations. This inquiry examines two geographic areas—Virginia’s Eastern Shore and the Midcontinent—in order to demonstrate how these diseases affected Native Americans differently. Aside from the negative effects of the introduction of new infectious diseases, Indigenous peoples endured genocide perpetrated by English settlers as a means to gain greater control of their lands. Lastly, Indigenous …
