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, …

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 …

Recruitment Marketing: How Do Wellness And Work-Life Benefits Influence Employer Image Perceptions, Organizational Attraction, And Job Pursuit Intentions?, Amy Christine Pytlovany

Dissertations and Theses

A global talent shortage is motivating employers to change the way they approach recruitment. To stay competitive, business leaders are strategizing new ways to attract employees and market their organizations to prospective employees. This research examined the impact of work-life and wellness programs on employer image perceptions (instrumental, symbolic, and experiential) and recruitment outcomes (organizational attraction and job pursuit intentions). It integrated these literatures to inform evidence-based organizational decision-making.

Study materials were developed with pilot testing conducted using Amazon Mechanical Turk (MTurk). Pilot 1 (N = 40) assessed the value of 32 types of benefits across traditional (e.g., health …

Assessing The Efficacy Of Virtual Experiments In The General Chemistry Laboratory, Cory Jerome Hensen

Dissertations and Theses

As more students enroll in chemistry courses, institutions are faced with increasing costs and limited laboratory space to keep up with the demand. One solution some institutions have turned to is the incorporation of virtual experiments into the curriculum, as this can lower costs and increase the availability of laboratory space. Some institutions have offered sections that complete all of their experiments in a virtual environment, others have offered sections that alternate between a traditional hands-on experiment and a virtual experiment, and some institutions have replaced only select experiments throughout the curriculum with a virtual experiment. To begin to be …

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 …

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 …

Would there be enough buy-in from the PSU department …

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 …

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 …

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 …

Experiences Of Early Childhood Educators Working With Teaching Strategies Gold®: A Narrative Inquiry, Sarah Kathryn Guyon

Dissertations and Theses

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 …

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 …

Reclaiming A Unified American Narrative Lexical, Grammatical, And Story Metaphors In A Discussion Of Polarized Identities, L. David Ritchie

Communication Faculty Publications and Presentations

As part of an on-going project to apply metaphor analysis to understanding the cultural polarization that has recently obstructed discourse about political and cultural issues in both the United States and Europe, this essay examines the lexical, grammatical, and story metaphors in a recent editorial column, by conservative columnist Ross Douthat, that also focuses on this topic. In a key section of the essay, Douthat uses a blend of complex grammatical and lexical metaphors to highlight the contrast between the traditional American identity narrative of settlement and conquest and a recently emerged liberal counter-narrative, which Douthat epitomizes by quoting former …

Microplastic Occurrence And Effects In Commercially Harvested North American Finfish And Shellfish: Current Knowledge And Future Directions, Britta Baechler, Cheyenne Stienbarger, Dorothy Horn, Jincy Joseph, Allison Taylor, Elise F. Granek, Susanne Brander

Environmental Science and Management Faculty Publications and Presentations

Commercial fisheries yield essential foods, sustain cultural practices, and provide widespread employment around the globe. Commercially harvested species face a myriad of anthropogenic threats including degraded habitats, changing climate, overharvest, and pollution. Microplastics are pollutants of increasing concern, which are pervasive in the environment and can harbor or adsorb pollutants from surrounding waters. Aquatic organisms, including commercial species, encounter and ingest microplastics, but there is a paucity of data about those caught and cultured in North America. Additional research is needed to determine prevalence, physiological effects, and population-level implications of microplastics in commercial species from Canada, the United States, and …

Maddox, Samantha Crabbe, Rinad S. Beidas, Lauren Brookman-Frazee, Carolyn Cannuscio, Judith Miller, Christina Nicolaidis, David Mandell

School of Social Work Faculty Publications and Presentations

Most autistic adults struggle with mental health problems, and traditional mental health services generally do not meet their needs. This study used qualitative methods to identify ways to improve community mental health services for autistic adults for treatment of their co-occurring psychiatric conditions. We conducted semistructured, open-ended interviews with 22 autistic adults with mental healthcare experience, 44 community mental health clinicians, and 11 community mental health agency leaders in the United States. The participants identified clinician-, client-, and systems-level barriers and facilitators to providing quality mental healthcare to autistic adults. Across all three stakeholder groups, most of the reported barriers …

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 …

Open City'S Abschied: Teju Cole, Gustav Mahler, And Elliptical Cosmopolitanism, Josh Epstein

English Faculty Publications and Presentations

This essay addresses Teju Cole’s Open City (2011), a deconstructed bildungsroman preoccupied with Gustav Mahler’s late compositions. Building on Theodor Adorno’s account of Mahler, the essay argues that Cole positions Julius’s violent subjectivity in dialectical tension with the patterns of consumption that inform both his and Mahler’s intellectual landscapes. Previous scholarship, though attentive to Cole’s cosmopolitanism, has ignored the novel’s fixation on Mahler: a Jewish Bohemian-Austrian composer whose cosmopolitan sensibilities led him to appropriate a range of literary and musical sources, Western and Eastern. These sources, Adorno argued, are mediated in Mahler’s music as “pseudomorphs” that unravel their own pretenses …

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 …
