Preventing Child Sexual Abuse And Juvenile Offending Through Parental Monitoring, Kelly E. Stewart

Dissertations and Theses

In this dissertation, I present three manuscripts to investigate the prevention of a range of crimes committed against, and by, youth, using parental monitoring or guardianship. In the first paper, I tested whether the routine activities of juvenile sexual offenders (JSOs) and their victims' caregivers was associated with the JSO being placed into a supervisory role, and whether subgroup differences existed in the use of modus operandi strategies between JSO supervisors and non-supervisors (Chapter II). Findings indicated that parents' need for childcare assistance predicted JSO supervisor status more strongly than perpetrators efforts to get the child alone or disruptions to …

Employee Experiences With A Newly Adopted Paid Parental Leave Policy: Equity Considerations For Policy Implementation, Dawn M. Richardson

OHSU-PSU School of Public Health Faculty Publications and Presentations

Purpose: Paid parental leave (PPL) policies offer immense opportunity to enhance health equity by providing financial stability to workers and promoting the health of families in the United States. Working in partnership with a local county government, which recently adopted a paid leave policy, we engaged in a qualitative substudy to enhance our understanding of how workers perceived and experienced the policy across levels of the socioecological framework. Methods: Working in partnership with Multnomah County, a large public-sector employer in Portland, OR that recently adopted a PPL policy, we collected qualitative data through focus groups with employees. Data were transcribed, …

A Data Collection Program For Reducing Ipv In Lgbtq+ Communities, Alexandra Michel, Nicholas Cheke, Lourdes Gonzalez, Rachel Greim

OHSU-PSU School of Public Health Annual Conference

Sexual and gender minority populations are not currently being accurately tracked or counted in most domestic violence (DV) and intimate partner violence (IPV) surveillance programs in Oregon. However, research indicates that LGBTQ+ populations experience IPV at rates comparable or even higher than heterosexual populations. Additionally, distrust of law enforcement and services designed around heterosexual experiences of IPV further reduce the ability of LGBTQ+ populations, particularly transgender women, to access IPV services. We propose that through the use of a PRECEED-PROCEED model, a program could be developed to more accurately collect sexual orientation and gender identity data by IPV service providers …

Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright

OHSU-PSU School of Public Health Annual Conference

Infectious hematopoietic necrosis virus (IHNV) is a member of the Rhabdoviridae family and causes infectious hematopoietic necrosis (IHN) disease in many salmonid species during the juvenile or “fry” stage of life. IHNV is endemic to Western North America and occurs in the Columbia River Basin, where Steelhead and Chinook salmon are the most abundant IHNV-vulnerable species. IHNV can cause an epidemic in wild or farmed stocks, killing 90-95 percent of the fish it infects. Transmission is currently understood to occur by direct exposure through the gills, and the virus is shed typically from asymptomatic or clinically ill carrier adults at …

School of Social Work Faculty Publications and Presentations

As interest in autism in adulthood grows, so does the need for methods to promote the inclusion of autistic adults in research. Our objective was to create practice-based guidelines for the inclusion of autistic adults, both as research team members and as study participants. We conducted an institutional ethnography of three closely related research partnerships that used participatory methods with autistic adults over the years 2006–2018. We used an iterative approach which combined discussions with community and academic partners and artifact review. Guidelines to promote the inclusion of autistic adults as co-researchers focus on being transparent about partnership goals, clearly …

Perceived Partner Responsiveness, Sleep And Pain: A Dyadic Study Of Military-Connected Couples, Annamarie Sophia O'Neill

Dissertations and Theses

The health-promoting influence of high-quality, supportive close relationships has been extensively documented, yet the mechanisms of this effect are less well-understood. Leading researchers have galvanized the field to test particular relationship processes and the mediating psychological processes they facilitate to pinpoint how close relationships exert their salutary effects. The purpose of this study was to investigate the influence of the intimacy process on health outcomes of sleep and pain and if this effect depends on the facilitation of psychological processes in a sample of veterans and spouses (collectively called military-connected couples; N=147). Sleep problems are highly prevalent among military-connected couples …

Addressing Changing Demographics In Environmental Justice Analysis, Aaron Golub

TREC Project Briefs

Since 1994, every Federal agency has a mandate to develop a strategy for identifying and addressing disproportionately high and adverse human health or environmental effects on low income populations and minority populations. In transportation planning this means including those communities’ voices in the planning process, and evaluating the social impacts early on.

A new report from the Federal Highway Administration (FHWA), prepared by Portland State University and ICF International, provides an in-depth analysis of national demographic trends and a synthesis of best long-range planning practices borne out of five case studies

Diversity In Ya: A Look At How Book Description Language Talks About Race, Brittney Finato

Book Publishing Final Research Papers

When exploring young adult literature, it is specifically important to research racial diversity because it can help show particular stereotypes, biases, and tropes that may be used in YA overall. This helps inform current issues or excellencies in the canon and leads to broader discussions about the importance of racial, and other, diversity in books generally. By developing methods to isolate racially diverse books in YA, extracting specific language from their Goodreads copy, and talking broadly about overall themes, I will analyze the types of language that book descriptions use when talking about race, if they do at all.

Urban Studies and Planning Faculty Publications and Presentations

This project’s goal is to lift up promising approaches, suggest new strategies and encourage honest conversations that result in public policy solutions to income and racial segregation and poverty. The overarching question that motivates this work is:

• What are effective policies and strategies that promote access to high-opportunity amenities for low-income families?

As a first step, the researchers surveyed efforts on the ground in the metropolitan areas encompassing Seattle, Washington; Portland, Oregon; and San Diego, California, to determine whether there were any candidates for deeper study. We selected these three metropolitan areas for several reasons. First, prior interaction revealed that …

Traffic Signal Consensus Control, Gerardo Lafferriere

TREC Final Reports

We introduce a model for traffic signal management based on network consensus control principles. The underlying principle in a consensus approach is that traffic signal cycles are adjusted in a distributed way so as to achieve desirable ratios of queue lengths throughout the street network. This approach tends to reduce traffic congestion due to queue saturation at any particular city block and it appears less susceptible to congestion due to unexpected traffic loads on the street grid. We developed simulation tools based on the MATLAB computing environment to analyze the use of the mathematical consensus approach to manage the signal …

Contrasting Local And Long-Range-Transported Warm Ice-Nucleating Particles During An Atmospheric River In Coastal California, Usa, Andrew C. Martin, Gavin Cornwell, Charlotte M. Beall, Forest Cannon, Sean Reilly, Bas Schapp, Dolan Lucero, Jessie Creamean, F. Martin Ralph, Hari T. Mix, Kimberly Prather

Geography Faculty Publications and Presentations

Ice-nucleating particles (INPs) have been found to influence the amount, phase and efficiency of precipitation from winter storms, including atmospheric rivers. Warm INPs, those that initiate freezing at temperatures warmer than −10ºC, are thought to be particularly impactful because they can create primary ice in mixed-phase clouds, enhancing precipitation efficiency. The dominant sources of warm INPs during atmospheric rivers, the role of meteorology in modulating transport and injection of warm INPs into atmospheric river clouds, and the impact of warm INPs on mixed-phase cloud properties are not well-understood. In this case study, time-resolved precipitation samples were collected during an atmospheric …

Arctic Security: The Race For The Arctic Through The Prism Of International Relations Theory, Michael Gregory Morgan Trujillo

Dissertations and Theses

The purpose of the thesis is to examine future international relations in the Arctic as a theoretical exercise based on realism and liberalism. As the ice cap shrinks, and the region's environment changes, developing costs will decrease allowing for resource-extraction while new transit routes emerge. The opportunities to develop resources and ship via the Arctic are economic and strategically valuable, altering the geopolitics of the region. This thesis seeks to explore how resource development and new transit routes will affect regional politics through the lens of two theories. The two theoretical approaches will examine states and actors' interests and possible …

Lidar Predictive Modeling Of Kalapuya Mound Sites In The Calapooia Watershed, Oregon, Tia Rachelle Cody

Dissertations and Theses

Archaeologists grapple with the problematic nature of archaeological discovery. Certain types of sites are difficult to see even in the best environmental conditions (e.g., low-density lithic scatters) and performing traditional archaeological survey is challenging in some environments, such as the dense temperate rain forests of the Pacific Northwest. Archaeologists need another method of survey to assess large areas and overcome environmental and archaeological barriers to site discovery in regions like the Pacific Northwest. LiDAR (light detection and ranging) technology, a method for digitally clearing away swaths of vegetation and surveying the landscape, is one possible solution to some of these …

Webinar: E-Bikes For Everyone: Electrifying Communities In New Ways, John Macarthur, Sergio Lopez

TREC Webinar Series

Electric bicycle (e-bike) use is a rising phenomenon in North America. In 2018, John MacArthur of Portland State University conducted a national survey to understand issues facing e-bike owners. Reducing physical exertion, conquering challenging topography and replacing car trips are a few of the most important reasons for buying an e-bike. The electric assist of the e-bike helps to generate more trips, longer trips and different types of bicycle trips. Through analysis it also became evident that e-bikes are making it possible for more people to ride a bicycle, many of whom are incapable of riding a standard bicycle or …

Stratospheric Polar Vortex Variability In The Northern Hemisphere: The Effects Of Climate Change On Polar Vortex Trends And Future Projections, John Earl Rogers

Dissertations and Theses

Regions that have experienced recent successive cold winters such as the Northeast of North America and Siberia have endured critical social and economic impacts from anomalous low temperatures in recent years, despite warming global temperatures. It is well known that the Tropospheric Polar Vortex (TPV), or jet stream, is a primary influence on many mid-latitude winter weather patterns. However, the strong circumpolar westerlies that maximize at around 60° latitude just above the tropopause, known as the Stratospheric Polar Vortex (SPV), can affect tropospheric circulation and thus winter weather in the Northern Hemisphere. Strong upward propagating waves can affect the geographic …

The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership: Analysis Of Multifamily Residents In Portland, Oregon, Edgar Bertini Ruas

Dissertations and Theses

Since the beginning of the 21st Century, the world has seen the rapid development of the so-called "sharing economy" or collaborative consumption (Botsman, 2010). One of the first areas affected by the shared economy is vehicle ownership. With the emergence of several new providers of mobility services, such as Uber and car2go, there has been the promise of changes to the traditional way of owning and using a vehicle (Wong, Hensher, & Mulley, 2017). One potential consequence of shared mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing …

Working Paper No. 14, Gramsci, Dugger And Hegemony, Devin Bales

Working Papers in Economics

This inquiry seeks to establish connections between William Dugger’s understanding of subreption leading to corporate hegemony with Antonio Gramsci’s understanding of power and the hegemon. Specifically, this inquiry examines the similarities between both authors’ descriptions and understandings of power in a civil society. Going further, I draw parallels between Gramsci’s description of ‘passive revolution’ as a key process for achieving hegemony and Dugger’s explanation of the role ‘subreption’ plays in the rise of corporate hegemony in the United States. Finally, this inquiry explores connections between Gramsci’s writings on ‘Americanism’ and Dugger’s research into ‘corporate hegemony’. While Dugger does not cite …

Pedpdx: Addressing Equity Through Citywide Pedestrian Planning, Michelle Marx, Francesca Patricolo
