Death, Grief, And Loss Through The Eyes Of Child: The Importance Of Teaching Children About Death Using Children's Literature, Sara Holzschuh

University Honors Theses

This thesis will explore how we view death as a death-denying society, along with the importance of teaching children about death and grief early on in their lives. When talking to children about death it is critical to refrain from abstract language and instead use death-specific language. Children need to understand that death is a universal experience, that death is irreversible, and that the body ceases all life functions at the time of death. This thesis will also discuss avenues for teaching children about death and argues that picture books are a fantastic way of introducing children to death. It …

Genome Editing Using Crispr-Cas9 In Annual Killifish Species, Keria Moritsugu-Vandehey

University Honors Theses

CRISPR-Cas9 genome editing has been used successfully to knock out genes in model organisms such as zebrafish, turquoise killifish, and cichlid fish. CRISPR-Cas9 genome editing has not been verified in the annual killifish, Austrofundulus limnaeus. We hypothesize that targeted editing of the tyrosinase gene in embryos of A. limnaeus will lead to fish without the ability to produce black pigment. Embryos at the 1-cell stage were injected with a Cas9 cocktail containing a mix of guide RNA molecules that target the genomic sequence of the tyrosinase gene and either an mRNA coding for the Cas9 protein or Cas9 protein. …

What Explains Male And Female Decision Making To Enter Law? Evidence From A Survey Of Us-Based Undergraduate Students, Abigail Cohen

University Honors Theses

The research conducted in this thesis aims to explain why fewer females than males choose law and pinpoint the explanation as to why they have disparate experiences in the field. The hypothesis is sex discrimination is to blame for the differences among female and male decision making. Sexual harassment and discrimination plays a very prominent role in male dominated fields and discourages females from joining those workforces. The research method for this experiment was an anonymous survey, sent out via social media and email. The survey method was chosen because it was meant to be a quick, yet effective way …

The Mirror Project: Reflections On The Experiences Of African-American Female Adolescents Experiencing Foster Care, Bahia Anise-Cross Degruy Overton

Dissertations and Theses

As the author Zora Neale Hurston says, "If you're silent about your pain, they'll kill you and say you enjoyed it." The Mirror Project (MP) aims to break this silence by giving voice to Black women who have experienced foster care in Portland, Oregon during their adolescence. In focus groups and interviews, participants shared their stories. Racial identity development theory, phenomenology and Afrocentric feminist epistemology provided lenses for gaining insight into their experiences in a predominantly white city. The MP revealed six themes: lack of youth engagement in foster care decisions, the need for a cultural lens in social work, …

Latine Dual Language Bilingual Education Teachers' Work Experiences, Nelly Noemi Patiño Cabrera

Dissertations and Theses

Given the increasing concern about the scarcity of Dual Language Bilingual Education (DLBE) teachers, it is crucial to understand the trends in teacher retention and attrition from the perspective of DLBE teachers themselves. DLBE teachers departing from their jobs imposes a significant burden on schools and students and affects the implementation of DLBE programs. To delve into this issue, this critical qualitative study focused on the work experiences of Latine K-5 Spanish/English DLBE teachers. Specifically, this study involved six participants divided into two groups of DLBE teachers in the teaching trajectory: three Latine K-5 Spanish/English DLBE teachers currently teaching in …

The Arab Spring Uprisings In Geopolitical Context, Jake Alan Rutledge

Dissertations and Theses

The question of why revolts, civil wars, and social unrest occur is central in the field of political science. This paper asks that question in the specific context of the 2011 Arab Spring uprisings as a revolutionary wave. Many theories of revolution and social unrest locate their causes in the internal characteristics of the country where they take place, such as the country's demographics or level of economic development. This paper examines the external situation of a country: its relationships with other states and the international community. This paper examines eighteen Arab countries in the Middle East and North Africa …

Persona Journey Mapping To Drive Equity During An Lms Transition, Kam Moi Lee, Kari Goin Kono, Megan Mcfarland

Office of Academic Innovation Publications

Technology systems that support learning–such as Learning Management Systems, or LMS’s–can change frequently in higher education. This often creates significant challenges for faculty-support staff during a transition–or migration–period. When equitable practice is deprioritized during these migrations, there is a high chance that stakeholders will experience adoption resistance, putting the project’s success and subsequent student experience at risk. Using a vignette and case study qualitative methodological approach, three researchers at a large urban university in the Pacific Northwest detail personas and journey mapping as an equitable design practice during a LMS migration on a rapid development timeline. This paper details how …

Mmwave Rat Optimization: Mac Layer Initial Access Design And Transport Layer Integration, Suresh Srinivasan

Dissertations and Theses

MmWave Radio Access Technology (RAT) is a promising technology for wireless communication due its large bandwidth and is already being deployed in 5G cellular and emerging WiFi technologies. MmWave systems use highly directional beams with narrow beamwidths to overcome the high path loss associated with their frequency bands. A mmWave radio can be used either in a standalone mode (where all radios use the same technology) or simultaneously with other technologies such as LTE and low frequency WiFi in a communication mode commonly referred to as integrated mode. This thesis proposes two methods to optimize mmWave RAT performance in both …

Oral Health And Older Adults: A Narrative Review, Martin S. Lipsky, Tejasvi Singh, Golnoush Zakeri, Man Hung

Institute on Aging Publications

Oral health’s association with general health, morbidity, and mortality in older adults highlights its importance for healthy aging. Poor oral health is not an inevitable consequence of aging, and a proactive, multidisciplinary approach to early recognition and treatment of common pathologies increases the likelihood of maintaining good oral health. Some individuals may not have regular access to a dentist, and opportunities to improve oral health may be lost if health professionals fail to appreciate the importance of oral health on overall well-being and quality of life. The authors of this narrative review examined government websites, the American Dental Association Aging …

2020 Racial Justice Protests In Portland, Or: An Analysis Of Radical Place-Making And Police Tactics In A Neighborhood Context, Claire Brumbaugh-Smith

Dissertations and Theses

During the George Floyd protests, police used tactics infrequently seen until now, including the use of tear gas and sonic weapons in contested spaces. Police tactics are presumably sanctioned by policing directives, but little is known about how these tactics may vary across space at a granular spatial level, or how they might be normalized over time. To address this knowledge gap, I used the concept of repertoires of protest control to characterize and quantify the tactics of the Portland Police Bureau (PPB) deployed on racial justice protesters during the 2020 racial justice protests and describe the role of these …

Individual And Structural Contributors To Implicit And Explicit Anti-Muslim Bias In The United States, Aeleah M. Granger

Dissertations and Theses

This dissertation consists of two manuscripts addressing the multifaceted nature of Islamophobia in the United States by examining explicit and implicit anti-Muslim bias on individual and structural levels. The first manuscript tests an ideology-threat-attitude-behavior model by estimating the simultaneous mediating effects of threat perceptions on the relationships between individual differences in ideology, Islamophobia (fear of Muslims), and support for an anti-Muslim police surveillance policy. This study (N = 603) finds that individuals who are higher in Social Dominance Orientation (SDO), Right-wing Authoritarianism (RWA), and Nationalism are more likely to perceive Muslims as realistic (power), symbolic (value), and terroristic (safety) …

Gen Z And Millennials Have An Unlikely Love Affair With Their Local Libraries, Kathi Inman Berens, Rachel Noorda

English Faculty Publications and Presentations

A phone fixation may seem at odds with an attraction to books. But the latter may offer a much-needed reprieve from the former. In our recent study of American Gen Z and millennials, we discovered that 92% of them check social media daily; 25% of them check multiple times per hour. Yet in that same nationally representative study, we also found that Gen Z and millennials are still visiting libraries at a healthy clip, with 54% of Gen Zers and millennials trekking to their local library in 2022. Our findings reinforce 2017 data from the Pew Research Center, which showed …

Five-Step Guide To Writing About African Children: A Satirical Homage To Decolonizing Our Minds And Challenging Stereotypes, Randall Yesmont, Bright Alozie

Black Studies Faculty Publications and Presentations

This essay is a work of satire, in the style of the late Binyavanga Wainaina’s “How to Write About Africa” and Bright Alozie’s “How to Write About Nigeria” and “How to Write About African Women.” In this satirical homage, we explore the pesky stereotypes that often accompany Western perceptions and writings about African children. We hope that stereotypes satirically highlighted in this piece shed light on the dangers of a single story while advocating for the recognition of the humanity, agency, voices, and dignity of African children.

Sustainable Leadership During Turbulent Times, Paul Marietta

Dissertations and Theses

Teachers, administrators, and staff in schools are leaving the profession at unprecedented rates. The principal pipeline has significantly decreased in the past years and our public school system is at a breaking point. Now more than ever, we need to focus on sustainable leadership during turbulent times and helping the organization, students, families, teachers-and also their leaders-thrive. This dissertation proposal follows the Portland State University (PSU) multi-paper format which comprises a compilation of three papers in a journal article style format, with sole or multiple authors, and although PSU policy does not require it, the topic of the papers in …

Indigenous Assimilation And Progressive Mirages: The Globalization Of American Narratives Of Educational Reform, Madhu Narayanan

Educational Leadership and Policy Faculty Publications and Presentations

In 1928, the Institute for Government Research released the Meriam Report, a massive study of the nation’s Native Americans. Unflinchingly rational, the report criticized federal policy, but it also set a high-minded vision for Native American progress. Celebrated by the press at the time, hailed by historians in the following decades (Bertolet, 2007; Kelly, 1983, Philp, 1977, Szasz, 1974; Downs, 1945), the report became perceived as a turning point in the treatment of Native Americans and signaled a renewed faith in government. A century later, these reforms appear as mirages. In this paper, I show how the Meriam Report cloaks …

Assessing Cool Corridor Heat Resilience Strategies For Human-Scale Transportation, Nicole Iroz-Elardo, Ladd Keith, Kristina M. Currans, Ashley Avila, Lauren Heath, Brenden J. Little, Ethan C. Wissler, Andrew J. Birkelbach

TREC Final Reports

Road pavement is a known contributor to the urban heat island effect. Several vendors are providing engineered pavements coatings—known as “cool pavement”—to reflect light and, therefore, reflect heat to reduce the thermal load of roads. Few of these cool pavements have been evaluated outside lab conditions, where they tend to rely heavily on surface temperature measurements with the assumption that lower surface temperatures result in lower ambient air temperatures in real-world practice. Further, while heat is detrimental to the pedestrian and cyclist experience and health, almost no research exists documenting the experience of the cool pavement on active travelers, including …

"The Feminist Coven Did It": Nigerian Women's Feminist Leadership And Coalition Against Police Brutality During The 2020 #Endsars Protests, Bright Alozie

Black Studies Faculty Publications and Presentations

The 2020 #EndSARS protest—a movement against police brutality and state violence in Nigeria—is an excellent locale for the historical study of African women’s activism and contributions to social movements. Young Nigerian women actively spearheaded this movement. Employing oral history methods, social media, and other primary sources, I place these women at the center of the narratives surrounding the #EndSARS protest. Their exceptional leadership and coordination contributed to the success of the most extensive youth-led protests in Nigeria’s contemporary history. In locating their individual and collective activism, I argue that history provided the roadmap for how they did effective activism since …

Afro-Latin Americans Living In Spain And Social Death: Moving From The Empirical To The Ontological, Ethan Johnson, Joy González-Güeto, Vanessa Cadena

Black Studies Faculty Publications and Presentations

This paper has three objectives. First, we establish that although Spain has attempted to distance itself from its role in the sub-saharan African slave trade and the significance blackness plays within its borders, there exists a significant population of people of African descent from Latin America living in Spain. Second, we show Black people are living what Sadiyah Hartmann refers to as the afterlife of slavery in Latin America. We claim it is worthwhile to take into account that Afro-Latin Americans are fleeing to the country that is largely responsible for them being in Latin America and the conditions of …

The Intersection Of Asset Management And Geographic Information Systems For University Facilities Maintenance, Andrew Westerlund Beland

Masters in GIS Practicum Reports

This project describes a proof of concept for developing a digital asset management system dashboard for water backflow assemblies at Portland State University (PSU) using a modified ESRI ArcGIS Online backflow solution. Asset management is crucial for optimizing the lifecycle of tangible assets, which ensures cost-effective operational efficiency and regulatory compliance. PSU manages over 250 backflow assemblies spread across the 50-acre campus and has traditionally relied on manual processes, which can lead to inefficiencies and potential transcription errors.

The system links spatial data with asset attributes for backflow devices, enabling field staff to update inspection results directly from mobile devices. …

A Genus In The Bacterial Phylum Aquificota Appears To Be Endemic To Aotearoa-New Zealand, Jean F. Power, Carlo R. Carere, Holly E. Welford, Daniel T. Hudson, Kevin C. Lee, John W. Moreau, Anna-Louise Reysenbach, Thijs J.G. Ettema, Multiple Additional Authors

Biology Faculty Publications and Presentations

Allopatric speciation has been difficult to examine among microorganisms, with prior reports of endemism restricted to sub-genus level taxa. Previous microbial community analysis via 16S rRNA gene sequencing of 925 geothermal springs from the Taupō Volcanic Zone (TVZ), Aotearoa-New Zealand, revealed widespread distribution and abundance of a single bacterial genus across 686 of these ecosystems (pH 1.2-9.6 and 17.4-99.8 °C). Here, we present evidence to suggest that this genus, Venenivibrio (phylum Aquificota), is endemic to Aotearoa-New Zealand. A specific environmental niche that increases habitat isolation was identified, with maximal read abundance of Venenivibrio occurring at pH 4-6, 50-70 °C, and …

Automation Of Productive Machinery. Bases For An Innovative Business Model, Carlos Guillermo Hernández-Cenzano, Angel Contreras-Cruz, Eduardo Humada-Tello

Engineering and Technology Management Faculty Publications and Presentations

Nowadays, some laboratories perform elastic properties tests for concrete or rock cores using equipment manufactured 50 years ago. The original data collection procedure uses analog and manual recordings, which can cause inaccuracies in the measurements taken during these trials The process is tedious and updated since each trial's measurement data is recorded manually. In this context, this study systematizes the process and proposes an automated data acquisition and recording system for this type of equipment, followed by a case study presenting a rock compression test.

App-Based Data Collection To Characterize Latent Transportation Demand Within Marginalized And Underserved Populations, Noelle L. Fields, Courtney Cronley, Stephen Mattingly, Nicole Iroz-Elardo, David Levine, Nithisha Gudipati, Cristine Highfill, Mary Kris Stringfelllow, Anna O'Dell, Rebecca Cole, Melody Huslage

TREC Final Reports

Our interdisciplinary team refined an app prototype, MyAmble, to gather data related to quantity of transportation disadvantage and latent demand, and to identify psycho-social-economic corollaries. MyAmble utilizes a traditional travel diary format but expands the type of trips measured to include 1) completed trips, 2) missed trips, and 3) latent travel demand. The app also measures the real-time perceived impact of transportation behaviors (realized and latent) on participants’ physical health, mental health, social engagement, and employment/academics. Finally, the app has a text-messaging feature, Travel Buddy, that is used to increase participant engagement and retention over longitudinal data collection. The project …

Examining The Multifaceted Impacts Of Drug Decriminalization On Public Safety, Law Enforcement, And Prosecutorial Discretion, Kelsey S. Henderson, Christopher M. Campbell, Brian C. Renauer

Criminology and Criminal Justice Faculty Publications and Presentations

This final report provides the findings of a multi-year project to understand the effects of successive drug policy efforts in Oregon. Since 2013, Oregon has implemented three changes that reclassified and lowered the seriousness of low-level drug possession offenses, with multiple years between each policy change: Justice Reinvestment in 2013, defelonization in 2017, and decriminalization in 2021. This project parses out the individual impacts of these unique events on law enforcement, prosecution, courts and sentencing, and public safety & health.
