Caring About Aftercare: Thesis Presentation Of Initial Findings, Sage B. Fuentes

University Honors Theses

While previous research has studied the impact of stigma and non-normative play within the BDSM and kink community, previous psychological research involving BDSM practitioners has not investigated the cultural practice of aftercare that tends to follow the highly sensationalized acts within the culture. The current study examines this cultural practice by giving a series of semi-structured interviews to assess the importance of aftercare and how it impacts negotiations and play. BDSM practitioners (n = 11) participated in audio recorded interviews regarding questions on identity, kink, aftercare, consent, and negotiation. 72.73% of individuals rated aftercare as mostly to largely important in …

Art Therapy And Dialectical Behavioral Therapy: A Workbook, Jasmine S. Griswold

University Honors Theses

Looking into the ways in which we treat anxiety and depression in both clinical and casual settings it seemed apparent that there are similar tools being utilized to alleviate the effects, but there didn’t seem to be a cohesion of these tools. With Dialectical Behavioral Therapy (DBT) a mindfulness based approach to therapy and the use of art as a tool to create dialogue in Art Therapy (AT) it seemed appropriate to combine the modalities to create a workbook that could be used on one's own or in conjunction with a therapist.

Collaborative Features Of Graphic Narratives: Research For "Lovely, Satisfied, Indifferent Eyes", Brigid K. Fitzpatrick

University Honors Theses

Graphic narratives, such as comics and graphic novels, innately include formal features that invite reader participation. Reading a graphic narrative means contributing to the work. I created a graphic novelette, Lovely, Satisfied, Indifferent Eyes, that prioritizes the conceptual collaboration between author and reader. I did this by enhancing the formal features of the gutter, visual voice, braiding, and temporal representation (time). Creating a graphic narrative that relies on reader participation allows the author and the work to benefit from the vast networks of diverse readers, made possible by the internet and the increased communication in our world as a …

Superhydrophobic Particle Ejections From Liquid Surfaces In Microgravity Environments, Elaina L. Gabriel

University Honors Theses

This paper explores a completely new avenue of microgravity fluidics that has not been systematically studied before, exploring superhydrophobic particle ejections from liquid surfaces in microgravity environments and quantifying the particle velocity varying particle. Superhydrophobic surfaces greatly reduce liquid-substrate contact. This allows for spontaneous ejection of floating particles in drop tower experiments. To quantify such phenomena, a drop tower experiment is constructed and tested. The Dryden Tower (DDT) is a laboratory facility at Portland State University that allows for the investigation of short duration exploration and research on Earth of 'micro-gravity' phenomena similar to that aboard orbiting spacecraft. Perhaps surprisingly, …

Erotic Manga, Its Artists, And The Pressures Of Censorship, Dominique Andrée Lief

University Honors Theses

Erotic manga (エロマンガ), a genre of adult-oriented Japanese comics is subjected to censorship that may seem irrelevant or confusing to people outside of the industry. Why is erotic manga censored? How is erotic manga censored? How does censorship affect erotic manga artists? These questions are examined through use of English academic sources, Japanese academic sources and news articles, and interviews with professional erotic manga artists translated into English.

Support From Inside Out: Exploring Whether Various Social Supports Assist In Reducing Prison Rule Violations, Sarah Renee Lazzari

Dissertations and Theses

Scholars argue that prison rule violations are a way to assess whether individuals are engaging in prosocial behaviors. Individuals who engage in prosocial behaviors, during periods of incarceration, are less likely to engage in behaviors that result in official rule violations. Decreasing rule violations is one way to work towards a safer prison environment, while also preparing individuals for release. The current study uses cross-sectional data form the 2004 Survey of Inmates in State and Federal Facilities, in order to examine whether multiple types of prisons programs, which will be framed as various types of social supports, influence the frequency …

Attrition And Psychotherapy, Jesse Barrington Homan

Dissertations and Theses

Attrition in psychotherapy, also known as dropout, is a problem that affects clients who terminate, their families, therapists, mental health systems, and the overall community. Research on attrition is vast. However, the majority of this research has been done post hoc, relied on quantitative methods, and looked primarily at client demographic variables as the predictors of attrition. This has resulted in inconsistent findings, offers little to no useful information about attrition, and appears to blame clients for failed therapy. There has been little research on attrition from the perspective of clients who terminate. This study was designed to answer the …

The Death Of Physical Media: The Dangers Of Streaming And The End Of The Home Library, Amelia Eichler

University Honors Theses

This thesis aims to provide an extensive look at the history of collecting film within the home, starting from pre-cinematic optical toys to today's use of streaming platforms. There is an extensive knowledge gap in the history of film collecting. Much of the information is anecdotal and providing an extensive background will close this gap. Contrasting the different technologies in the home allows for people to see how film collecting practices have evolved. Streaming is currently a new phenomena that has taken over the industry and changed the structure of the home library. Rather than aid the home library, this …

Behavioral Analyses Of Zalophus Californianus And Eumetopias Jubatus At Bonneville Dam As Tools To Understand Salmonid Take And Inform Regulation Changes, Coral A. Bailey

University Honors Theses

Both Zalophus californianus and Eumetopias jubatus are species known to travel upriver into the Columbia River, reaching as far as the Bonneville Lock and Dam. Bonneville Dam works with federal agencies to hatch and protect salmonids within the Columbia River. Pinnipeds at the dam have been studied since the 1980's in an effort to understand their behaviors and feeding patterns on endangered salmon species. Since 2006, the hazing of Z. californianus and E. jubatus has gone on, showing little effectiveness in lowering the sea lion's consumption rates (ranging from 0.4-5.8% annually). Behavioral analyses conducted during the spring salmon run of …

Critique Of European Union Intervention In Mediterranean Migration: An Examination Of How Territory Can Be Used To Understand Migration Phenomena, Erin B. Bangs

University Honors Theses

Migration has existed virtually as long as humans have. Migration as a social phenomenon is nothing new, however, the way migration and migrants themselves have come to be treated in the legal and political sphere has evolved over time. Today, a decent majority of democratic state governments view and respond negatively to migrants attempting to enter their borders. This is painfully obvious in the case of Mediterranean migration, primarily from Africa to Europe by way of the Mediterranean Sea. What is happening in the Mediterranean is a humanitarian crisis. This work critiques the intervention of the European Union in the …

Research regarding the effects of positive early childhood experiences on long term learning and success is drawing more attention to early childhood education programs than ever before. Promises on the federal and state level of better pay for early childhood educators and "high quality" publicly funded early childhood education programs is an exciting and long-awaited vision by both families and early childhood educators. However, with federal and state funding comes the need for justification of those funds through different measurement structures. One of the widely used measurement structures is the Teaching Strategies GOLD® preformatted, portfolio style assessment system. Teaching Strategies …

Investigating The Origins Of Toxins Present In Electronic Cigarette Aerosols, Shawna Vreeke

Dissertations and Theses

The purported safety of electronic cigarettes has come under scrutiny with the significant increase of lung related illnesses starting in the summer of 2019. Public view has started to shift towards understanding the potential negative health impact associated with these devices. While many investigations indicate probable hazards present in e-cigarette aerosols, inter-laboratory assessments are wide ranging and can be contradictory. Due to the novelty of this field, relatively little is known about these products. In this work, the identification and quantification of inhalation toxicants such as formaldehyde, acrolein, acetaldehyde and dihydroxyacetone are reported. Results of the investigation of the ability …

Spontaneous Recombination Of Short Rnas To Increase Length And Complexity In Prebiotically Plausible Conditions, Benedict Arthur Smail

Dissertations and Theses

The RNA World hypothesis is an influential theory of how life arose on earth which posits that the earliest life forms carried out essential activities with RNA catalysts instead of proteins. Substantial evidence to support this theory comes from among others, the fact that the ribosome is a ribozyme, the existence of small RNA catalysts capable of high activity, and self-assembling ribozymes such as the Azoarcus ribozyme. Additional support has been provided by the directed evolution of various ribozymes and the reputed prebiotic synthesis of nucleotides and small RNA oligomers. However, it has long been challenging to show how long …

Noncompliance With Land Acquisition In Vietnam: A Policy Tools Approach, Dang Van Nguyen

Dissertations and Theses

The Doi Moi policy (economic reform) launched in 1986 has resulted in economic boom for Vietnam. The nation with a population of around 95 million people recently joined the middle-income nation group and became a "major development success story." In the land sector, while the land ownership is controlled by the State, the privatization process of land rights has brought Vietnamese people five fundamental rights over land. To meet increasing demands of economic development and urban expansion, the central government of Vietnam (CGV) has implemented land-taking policy from early 1990s. The land acquisition policy, on the one hand, has attracted …

Family, School, And Forms Of Capital, Sonja Taylor

Dissertations and Theses

This dissertation contains three separate but related papers, each with a different focus. In the three papers, I sought to gain a deeper understanding of how different forms of cultural and social capital appeared in the relationship between families and schools. The first paper covers an interview study exploring how teachers in elementary school understood and used email to facilitate partnership with parents, a form of social capital that has the potential to benefit families from all class backgrounds. The second paper investigates the relationship between socioeconomic status, bonding social capital and cultural capital; I tested whether social capital affected …

The Many Wives Of General August V. Kautz: Colonization In The Pacific Northwest, 1853-1895, Nicole Ann Kindle

Dissertations and Theses

This thesis is about the colonization of the West, with an emphasis on the Pacific Northwest from 1853 to 1895. It analyzes the historical processes occurring as America expanded westward through the lens of the Kautz family. August Kautz and his wives tell the story of colonization through unique and vastly different ways. This thesis argues that a microanalysis of the Kautz family history tells a greater story of colonization, one rife with complicated layers influenced by race, class, and societal expectations that shaped individual roles within colonization.

August Kautz was a lieutenant when he first arrived in the Pacific …

The Impact Of Integrating Traditional Ecological Knowledge In Summer Camps On Middle School Students' Understanding Of The Nature Of Science, SapoóQ'Is WiíIt'es Ciarra Solina Greene

Dissertations and Theses

The Nature of Science (NOS) and traditional ecological knowledge (TEK) have commonalities in the knowledge bases: they are both ways of explaining the natural world; founded on a set of practices and the historical accumulation of knowledge; and part of the education is learning practices and developing knowledge of the concepts that are foundational to the disciplines. Throughout the United States, schools are attempting to strengthen students' understanding of NOS through various approaches, although few have adopted the integration of TEK into curriculum. This research assesses two summer camps for middle school students that are science focused, one with TEK …

Impact Of Titanium Dioxide Nanoparticles On Nutrient And Contaminant Reduction In Wastewater Treatment Wetlands, Madeline Hubbard

Civil and Environmental Engineering Master's Project Reports

Metallic nanoparticles are found in a variety of commercial products and industrial processes, and have become more common in the last few decades. As nanoparticles are toxic to biota and have the potential to spread other types of contamination, their increased use has become a concern. Research into the transport of nanoparticles in subsurface and surface waters shows a wide range in mobility, but that they are most likely to collect in systems with low linear velocities and high organic content. As a result, wetlands are the most vulnerable to nanoparticle contamination. Wetlands receiving and treating wastewater effluent have an …

Urbanicity As A Moderator Of The Relationship Between Stigma And Well-Being Outcomes For Individuals With Serious Mental Illnesses, Emily Leickly

Dissertations and Theses

During the deinstitutionalization movement in the 1960s, community mental health centers and supportive and affordable housing for people with serious mental illnesses (SMI) was concentrated in economically disadvantaged urban centers. Today, these urban centers are becoming increasingly gentrified and unaffordable for people with SMI. Affordability is no longer synonymous with urban living, and supportive housing for people with SMI is increasingly found in non-urban areas. Given this shift, it is important to understand the potential impacts of non-urban living on people with SMI. Non-urban environments provide potential benefits for the general population, including reduced traffic and increased proximity to the …

Fractals As Basis For Design And Critique, John Charles Driscoll

Dissertations and Theses

The design profession is responding to the complex systems represented by architecture and planning by increasingly incorporating the power of computer technology into the design process. This represents a paradigm shift, and requires that designers rise to the challenge of both embracing modern technologies to perform increasingly sophisticated tasks without compromising their objective to create meaningful and environmentally sensitive architecture. This dissertation investigated computer-based fractal tools applied within a traditional architectural charette towards a design process with the potential to address the complex issues architects and planners face today. We developed and presented an algorithm that draws heavily from fractal …

Audio Beat Detection With Application To Robot Drumming, Michael James Engstrom

Dissertations and Theses

This Drumming Robot thesis demonstrates the design of a robot which can play drums in rhythm to an external audio source. The audio source can be either a pre-recorded .wav file or a live sample .wav file from a microphone. The dominant beats-per-minute (BPM) of the audio would be extracted and the robot would drum in time to the BPM. A Fourier Analysis-based BPM detection algorithm, developed by Eric Scheirer (Tempo and beat analysis of acoustical musical signals)ⁱ was adopted and implemented. In contrast to other popular algorithms, the main advantage of Scheirer's algorithm is it has …

Fault Deformation At The Base Of And Within The Crescent Formation Along The Dosewallips River, Olympic Mountains Peninsula, Washington, Usa, Christine Meryl Maher

Dissertations and Theses

The Olympic Mountains, in the cost ranges of northwest Washington, expose a Cenozoic accretionary complex east of the Cascadia Subduction Zone. Accreted material consists of metasedimentary deposits thrust eastward beneath a basaltic terrane (i.e., the basaltic Crescent Formation and the basal Blue Mountain Unit [BMU] turbidite) along a major fault, the Hurricane Ridge Fault (HRF). Recent isotopic dating of zircons from the BMU indicate that it is about 8 my younger than the basalt, implying another major fault may exist east of the HRF, between the BMU and the Crescent Fm. Field observations, data, and samples for microstructural analysis were …

Modeling And Control Of Magnetic Gear Dynamics In A Wind Turbine Drivetrain, Danielle Vournas

Dissertations and Theses

This thesis looks at the modeling and simulation of linear and nonlinear magnetic gear dynamics in a wind turbine drivetrain. The objective is to lay the groundwork for analysis, modeling and optimization of control structures focused on pole-slip prevention. A classical mechanical two-mass torsion spring model is used as the basis for developing the dynamic system equations and Simulink models. The wind turbine torque input to the low speed rotor is modeled as a disturbance input, the generator torque is modeled as a controlled input, and the high-speed rotor speed is the only measured output. The nonlinear dynamics are linearized; …

Comparative Examination Of Two Police Departments In Portland, Oregon’S Greater Metropolitan Area, Analyzing Assault Related Offense Reports Against: Departmental Community-Policing Practices And Clearance-Rates, Elizabeth R. Ackerman

University Honors Theses

Community policing is touted as the solution to fostering restoration between communities and policing agencies across the United States. However, this remains a widely unregulated policy area where minimal assessments of available data exist on the effectiveness of community policing reform. Given the nature of police brutality and the struggles of policing agencies across the United States there is increasing need to measure outcomes. This research finds that community policing does serve as a proactive tool for crime rate reduction and prevention.

The Influence Of Age At Migration On Criminal Offending Among Foreign-Born Immigrants, Omar Melchor-Ayala

Dissertations and Theses

Domestic and international events -- such as the recent migrant caravans from Central and South America, and the records number of migrant children detained at the border -- have brought renewed attention to the adaptation of immigrants in the United States. More specifically, questions regarding whether the population of immigrants is driving the "crime problem," have taken center stage. Immigrants vary significantly in terms of when they migrate into the country. According to the Current Population Survey (CPS), the population of approximately 12 million foreign-born immigrant children living in the United States is split in terms of their age and …

Connecting Local-Scale Heavy Precipitation To Large-Scale Meteorological Patterns Over Portland, Oregon Using Observations And Climate Models, Christina Marie Aragon

Dissertations and Theses

Precipitation timing and magnitude is essential to human, ecological, and economic systems. Climate change may be altering the character of precipitation locally to globally, thus it is vital that resource managers, practitioners, and decision makers understand the nature of this change. This thesis was conducted in partnership with the City of Portland Bureau of Environmental Services (BES), and the Portland Water Bureau (PWB) in order to support resiliency planning around precipitation and precipitation extremes.

This work has two primary phases, which are discussed in chapter 2 and 3 of this thesis. The first phase of this research entails characterization of …

Stormwater Treatment Effectiveness Of Established Bioretention Facilities In Portland, Oregon, Emma Rose Kohlsmith

Dissertations and Theses

Bioretention systems are commonly used to treat and detain stormwater runoff and help mitigate for many negative effects of urbanization. Despite the widespread use of bioretention systems, few field-based studies have assessed how these facilities affect water quality many years after installation. The goal of this project is to assess the pollution reduction effectiveness of lined bioretention facilities that have been in use and functioning for 4-8 years. To meet this objective, this project measured water quality characteristics of stormwater flowing into and out of seven facilities installed throughout Portland, Oregon during real storm events. Stormwater grab samples were taken …

Tracking Center Of Mass With Limited Inertial Measurement Units, Connor Nathaniel Morrow

Dissertations and Theses

Wearable motion tracking systems pose an opportunity to study and correct human balance and posture during movement. Currently, these observations are either being conducted in laboratories with the use of camera systems and markers placed on the body, or through the use of suits containing large numbers (15-20) of inertial measurement units. However, to aid with rehabilitation of individuals with impaired balance, there needs to be an option to collect these observations outside of clinics and without incurring much cost from the user. I have focused on three inertial measurement units, one placed on each shank and one placed on …
