An Assessment Of Bicycle Detection Confirmation And Countdown Devices, Christopher Monsere, Sirisha Kothuri, David S. Hurwitz

PSU Transportation Seminars

For a person on a bicycle at intersections, trail crossings, or midblock locations that are signalized, knowing that they have been detected and how long they must wait to receive a green indication is valuable information. This presentation will summarize the findings from the online survey (1,048 responses), observed behaviors (2,428 persons on bicycle), and an intercept survey ( 234 persons) to understand blue light feedback devices and countdown timers at signalized intersections.

Findings suggest that the design where the blue light was embedded in the sign was more visible to cyclists and observed by higher proportions of cyclists in …

What Does It Mean To Be Deaf? Changing Meanings Of Deafness, Communication Technology, And Beliefs About Normality In The Us, Kathryn Elizabeth Burrows

Dissertations and Theses

How deafness is perceived as a problem by society dictates what types of technologies are leveraged to address the problem, and, conversely, available technologies shape how deafness is perceived. In this dissertation, I draw on multiple methods to explore the meanings of deafness in the US since the early 18^th century to the present, examine how the meanings of deafness in those eras shaped deaf technology, and assess how available technologies shaped how deafness was understood. Using primary and secondary historical sources, I identify that every era identifies a different "problem of being deaf" and it is that problem …

Fulfilling A Wish List: Creating An Oer Beginning Spanish Textbook And Curriculum, Jenny Ceciliano, Lisa Notman

World Languages and Literatures Faculty Publications and Presentations

This report discusses the experience of creating and implementing a new open educational resource (OER) first-year Spanish textbook and curriculum at Portland State University in Portland, Oregon. The project began with a long wish list of features. We hoped for a program that would be structured enough to support graduate teaching assistants with little teaching experience, but flexible enough for experienced instructors to make adjustments based on their own expertise, current events, or their unique group of students. We wanted the program to be inclusive and centered on diverse, authentic voices. We wanted to focus on topics that would be …

Autonomous Farming With Uavs, Pallavi Agrawal, Karthik Manjunath, Cherokee Rawls, Sujitha Raj Rajagopal, Riad Alharithi, Kamal Thapa

Engineering and Technology Management Student Projects

As the global need for food grows, agriculture is adapting autonomous farming techniques to scale in response. One of the most useful tools are UAVs (Unmanned Autonomous Vehicles), which are providing invaluable information and assistance to farmers. In some countries, UAVs are being rapidly embraced, while in others this progress is much slower. For a number of reasons, the United States has not broadly adopted this technology in assisting agricultural practices. In this article, we focus on the challenges companies and farmers are facing in making use of UAVs and what might be done to push this technology into widespread …

Model Optimization For Resource Allocation In A Consulting Firm, Riad Alharithi, Karthik Manjunath, Sara Ferdousi, Vladislav Ruchin, Jennifer Lynn Zeitouni

Engineering and Technology Management Student Projects

Assigning employees with multiple skill sets to projects at the right time has long been a challenge in professional settings. Whether it is assigning a salesperson to a product, an employee to a task, or a company to a project, many variables affect such decisions and make them taxing for managers and owners. In this project, an optimization issue observed in a team member’s workplace is being addressed.. The aim is to efficiently allocate employees to different concurrent projects. The firm's organizational structure is similar to a Project Management Office (PMO) that has an employee pool with varying skill sets …

Social Mobility, Adolescents' Psycho-Social Dispositions, And Parenting, Dara Shifrer, Heili Pals

Sociology Faculty Publications and Presentations

Psycho-social dispositions and parental influence are central in early status attainment models. We apply the Social Structure and Personality framework to investigate the contributions of adolescents’ psycho-social dispositions to social mobility, and then the contributions of parents’ socioeconomic status (SES) and parenting to adolescents’ psycho-social dispositions. The Kaplan Longitudinal and Multigenerational Study includes data on two generations of respondents: the first-generation of respondents was observed from seventh grade in 1971 until midlife, and the second-generation, their children, was observed from adolescence to young adulthood. We find that upward social mobility is inhibited by poor psycho-social dispositions, particularly by negative …

Field-Specific Cultural Capital And Persistence In College Majors, Ned William Tilbrook, Dara Shifrer

Sociology Faculty Publications and Presentations

We investigate the possibility that Bourdieu’s concept of cultural capital, ways of being that facilitate assimilation to the dominant culture, is field-specific in its manifestation and intergenerational transmission. We focus on a field of central economic and academic interest: STEM. Data on around 13,000 undergraduates from the large nationally representative High School Longitudinal Study of 2009 indicate that parents’ STEM-specific cultural capital positively contributes to youth’s selection of and persistence in STEM majors in the form of parents’ STEM education. We find that transmission is enacted through youths’ field-specific institutionalized cultural capital (e.g., STEM grades and test scores), field-specific embodied …

Who We Are: Focus On… Student Identity, Yarina Aguilar Becerra, Cecilia Diojuan, Jasmine Walker, Neera Malhotra, David Peterson Del Mar, Vicki Reitenauer

University Studies Faculty Publications and Presentations

In short

• Increasingly, professionals in higher education are acknowledging the short- and long-term impacts on individuals and communities of institutional failures to create welcoming, inclusive, and caring environments for traditionally underrepresented students.
• Student voices, reflecting on their lived and felt experiences in college, have been less frequently present in the discussions about inclusion in higher education.
• Listening to students from underrepresented groups has the potential to redefine and renew how we understand education and ourselves, offering a template and a foundation for the dense network of relationships that a student-focused institution of higher education ought to aspire to and build …

Fandom In The Digital Age: Examining Parasocial Relationships Between Fans And Music Artists On Instagram, Brittani Wert

University Honors Theses

With the rise of social media as a cultural staple in entertainment industries such as music, Instagram changes the landscape of the artist-fan connection and muddles the boundaries of parasocial relationships in a digital space. While a wealth of research exists on how fans perceive mediated relationships, the perspective of the artist and how they navigate this connectivity is missing from the discourse. This study builds on the current literature surrounding mediated artist-fan interactions and examines how music artists use Instagram to build strong, loyal relationships with fans through the lens of parasocial relationships. Through interviews with up-and-coming artists and …

Addressing And Supporting Mental Health Today: Society-Wide And In Hospital Emergency Departments, Kira La Sage

University Honors Theses

Mental health has become one of the most pressing public health issues of the 21st Century. Westernized societies offer much of their attention to childhood obesity, to COVID-19, to undiagnosed and diagnosed Americans living with diabetes. America even sees extended U.S. Senate hearings focusing on opioid use and abuse. Each of these concerns legitimately commands public health official attention, but what the world does not see is any level of sustainable attention given to emotional and mental health crises affecting tens of millions in Westernized countries. Suicide, the most serious of mental health crises, has become the second leading cause …

Expanding Temperature Sensing For The Orion Bms 2, Samuel J. Parker

University Honors Theses

Formula SAE (FSAE) is an annual collegiate design competition that takes place across the globe. Portland State University’s team, Viking Motorsports, was committed to designing an Electric Vehicle (EV) for the 2021 FSAE competition. The team designed a completely custom lithium-ion cell battery that is managed by an Orion BMS 2 battery management system. The FSAE rulebook requires a robust temperature monitoring system for any EV power supply. The Orion BMS 2 can only directly collect data from eight temperature sensors, which is not enough to meet FSAE regulation. However, the BMS can be configured to monitor many more sensors …

Understanding The Effect Of Dietary Palmitic Acid On Glycolysis During Innate Immune Memory In Macrophages, Khaleda A. Aqaei

University Honors Theses

Trained immunity is long-term innate immune memory induced by a primary stimulus, which leads to hyper-inflammation upon secondary stimulation with a homologous or heterologous ligand. Trained immunity is mediated by epigenetic and metabolic reprogramming of the target cell and leads to modification of gene expression and cellular function. Classically, trained immunity is initiated by β-glucans, an inflammatory molecule found on the exterior of fungal species. Interestingly, our lab has recently described that dietary fatty acids can initiate trained immunity, working through similar pathways as β-glucans. Specifically, our data show that a pre-treatment with a specific dietary saturated fatty acid (SFA), …

Gender Deviants: Subverting Regulatory Power In Medical Institutions, Ursa Nuffer-Rodriguez Mx.

University Honors Theses

Medical and psychiatric institutions have a long history of regulating and pathologizing the bodies of non-normative individuals. The harmful normativity of these institutions is particularly salient for trans* people pursuing gender-affirming medical care, as popular media representations of trans* identity reinforce narratives of certainty and aspirations towards cisgender standards of corporeality which rarely map onto authentic narratives of trans*ness. For the gender deviant subject, who conceives of hirself beyond these hegemonic notions of identity, navigating these institutions often requires a false projection of identity that fits the standard narrative, simply as a means to an end. In doing so, the …

A Small Rna Is Functional In Escherichia Fergusonii Despite Containing A Large Insertion., Austin P. Wright, H. Auguste Dutcher, Brianna Butler, Timothy J. Nice, Rahul Raghavan

Biology Faculty Publications and Presentations

Bacterial small RNAs (sRNAs) are important regulators of gene expression; however, the impact of natural mutations on sRNA functions has not been studied extensively. Here we show that the sRNA MgrR contains a unique 53 bp insertion in Escherichia fergusonii, a close relative of Escherichia coli and Salmonella enterica. The insertion is a repetitive extragenic palindromic (REP) sequence that could block transcription, but full-length MgrR is produced in E. fergusonii, showing that the insertion has not affected sRNA production. Additionally, despite containing the large insertion, the sRNA appears to be functional because deletion of mgrR made E. fergusonii …

Deep Learning Approach For Screening Autism Spectrum Disorder In Children With Facial Images And Analysis Of Ethnoracial Factors In Model Development And Application, Angelina Lu, Marek Perkowski

Electrical and Computer Engineering Faculty Publications and Presentations

Autism spectrum disorder (ASD) is a developmental disability that can cause significant social, communication, and behavioral challenges. Early intervention for children with ASD can help to improve their intellectual ability and reduces autistic symptoms. Multiple clinical researches have suggested that facial phenotypic differences exist between ASD children and typically developing (TD) children. In this research, we propose a practical ASD screening solution using facial images through applying VGG16 transfer learning-based deep learning to a unique ASD dataset of clinically diagnosed children that we collected. Our model produced a 95% classification accuracy and 0.95 F1-score. The only other reported study using …

Guarding Against Strain: The Moderating Role Of Nonwork Experiences In The Relationship Between Work-Related Hypervigilance And Strain In Correctional Officers, Samantha Getzen

Dissertations and Theses

Correctional officers (COs) are expected to remain alert in order to maintain safety within the potentially hostile prison environment. As a result, COs experience high levels of work-related hypervigilance (WHV), which has been associated with negative health and wellbeing outcomes for COs. This study examines nonwork experiences as potential boundary conditions for the relationship between WHV and strain outcomes. It was hypothesized that nonwork experiences (psychological detachment, relaxation, mastery experiences, and exercise) would weaken the relationship between WHV and strain outcomes (emotional exhaustion, physical symptoms and impaired sleep). Data were analyzed from 166 COs in Oregon. A series of hierarchical …

Proximal Policy Optimization For Radiation Source Search, Philippe Erol Proctor, Christof Teuscher, Adam A. Hecht, Marek Osiński

Electrical and Computer Engineering Faculty Publications and Presentations

Rapid search and localization for nuclear sources can be an important aspect in preventing human harm from illicit material in dirty bombs or from contamination. In the case of a single mobile radiation detector, there are numerous challenges to overcome such as weak source intensity, multiple sources, background radiation, and the presence of obstructions, i.e., a non-convex environment. In this work, we investigate the sequential decision making capability of deep reinforcement learning in the nuclear source search context. A novel neural network architecture (RAD-A2C) based on the advantage actor critic (A2C) framework and a particle filter gated recurrent unit for …

Building A Biomechanical Model Of A Rat Forelimb, Joshua Nathaniel Eric Mak

Dissertations and Theses

This paper presents a biomechanical model of the rat forelimb to test theories of determining viscoelastic muscle parameters. Several biomechanical models of rat hindlimbs have been developed and have explored the effects of multi-muscle control during locomotion. The forelimb model uses two ball-and-socket joints to model clavicle and scapula movement. A third ball-and-socket joint is used at the shoulder and two hinge joints are used at the elbow and wrist. Scapula motion is further constrained by muscle and spring elements. Each forelimb has 11 degrees of freedom, and 23 Hill-type muscles. The model has been created in Animatlab, which includes …

Online Activism And Real Life Environmentalism, Emily Grace Anderson

Dissertations and Theses

Past and present human activities have created and accelerated an array of environmental catastrophes and various systems in the environment remain under threat as a result of human behavior. In hopes of mitigating environmental consequences, a social movement has arisen to encourage people to behave in ways that are more environmentally sustainable. Research shows that individual behavior choices impact the environment, and this influence can be used to positively affect the environment through engagement in pro-environmental behavior. Like with many other social movements, the internet has been a tool in spreading awareness of a cause and allowing people the opportunity …

The Worth Of Risk: Political Participation And Risk Perceptions, Siri Grubb

Dissertations and Theses

This study draws on concepts from political and risk communication to inform our understanding of what motivates people to be politically active. Inspired by concerns that traditional models of participation do not perform as well among younger and more diverse populations, alternate variables are considered including risk perceptions surrounding policy issues and political parties. Results show that established political variables such as political interest and civic duty remain strongly associated with participation, while offering support for several new variables of interest from the risk communication literature. In the present study, threat and efficacy perceptions explained additional variance in political participation …

My Mountain, Your Mountain, Our Mountain: Incorporating Emotional And Sensory Experiences In Mapping Sense Of Place In Mount Hood National Forest, Alicia Ranae Milligan

Understanding the complex connections humans have with landscapes is necessary for successful land management and planning practices. Only within the last few decades has mapping the values of forest users been used to produce data that can be incorporated into forest planning as a means to better understand social and environmental dynamics. This research used sense of place web mapping coupled with interviews to understand forest users' emotional and sensory experiences within the Mount Hood National Forest and to improve future sense of place mapping research. Two objectives were addressed in this research: 1) develop a typology of individuals' emotions …

Electronic Resource Management In A Post-Plan S World, Jill Emery, Graham Stone

Library Faculty and Staff Publications and Presentations

cOAlition S and research funding policies mean open access content is no longer a "trend" but rather another consideration of content management for librarians and libraries. In 2018, the authors of this article launched a new version of TERMS (Techniques for Electronic Resources Management). TERMS 2.0 envisages a post-Plan S e-resources life cycle blending e-resources and open access content management. This article outlines how open content management can dovetail into current e-resource management tactics across six TERMS: Investigation of material, procurement and licensing of content, implementation, troubleshooting of problems, evaluation and preservation, and sustainability concerns. Lastly, we reflect on the …
