Daylighting Analysis: Yost Grube Hall, L. Patterson, C. Hardman

Research-Based Design Initiative

The goal of this research is to produce a daylight and energy analysis of the Yost Grube Hall Ankeny ‘Net Zero’ Multi-Family Housing project.The examination of current daylight levels provides information on what is gained or lost in regards to daylighting and net-zero goals. A focus on the progression of the surrounding neighbourhood development will guide the different daylight studies. This combined with the other strategies employed by YGH in their design efforts forms a narrative about the realities of ‘Net-Zero’ architecture and the various routes to success.

Drivers Of Urban Sprawl In Urbanizing China – A Political Ecology Analysis, Yiping Fang, Anirban Pal

Urban Studies and Planning Faculty Publications and Presentations

Chinese cities have undergone a process of urbanization that has resulted in significant urban sprawl in the past 20 years. This paper uses the 'ecology of actors' framework to analyze the interactions between various state, market and civil society players that result in excessive land conversion from agricultural to urban use. The paper shows that under the existing institutional setting, the interests of most actors involved in the process are aligned towards greater land development and growth. The more land is developed, the more land lease revenue for the local government, the more profit for developers, and the more opportunities …

An Inductive Ethnographic Study In Elderly Woman Technology Adoption And The Role Of Her Children, Noshad Rahimi, Antonie J, Jetter, Charles M. Weber

Engineering and Technology Management Faculty Publications and Presentations

Elderly woman strives to have a streamlined life surrounded by ease and familiarity. As she is aging, her desire for simplicity grows, her self-efficacy weakens, her prudency intensifies and her overall inclination toward status quo strengthens. As a result, she delays, or refuses, making any decision that might bring complexity and disrupt the continuity in her life, particularly new and unfamiliar technologies (which often bring complexity, before providing ease). Consequently, her technology adoption has a much lower rate than that of other demographics. To open the black box of elderly woman technology adoption process, this study focuses on the role …

Consistency Thresholds For Hierarchical Decision Model, Mustafa S. Abbas, Dundar F. Kocaoglu

Engineering and Technology Management Faculty Publications and Presentations

The objective of this research is to establish consistency thresholds linked to alpha (α) levels for HDM's (Hierarchical Decision Model) judgment quantification method. Measuring consistency in order to control it is a crucial and inseparable part of any AHP/HDM experiment. The researchers on the subject recommend establishing thresholds that are statistically based on hypothesis testing, and are linked to the number of decision variables and a level. Such thresholds provide the means with which to evaluate the soundness and validity of an AHP/HDM decision. The linkage of thresholds to a levels allows the decision makers to set an appropriate inconsistency …

Managing The Ethical And Risk Implications Of Rapid Advances In Artificial Intelligence: A Literature Review, Taylor Meek, Husam Barham, Nader Beltaif, Amani Kaadoor, Tanzila Akhter

Engineering and Technology Management Faculty Publications and Presentations

The development of emergent technologies carries with it ethical issues and risks. We review ways to better manage the ethical issues and risks of one emerging technology: Artificial Intelligence (AI). Depending on how AI's development is managed, it may have beneficial and/or deleterious effects. The processing capacity of Tianhe-2, the world's fastest supercomputer, by some measures, exceeds the processing capacity of a single human brain. but at a prohibitive processing/power consumption ratio and physical size. Given the current pace of AI R&D activities, some estimates in the literature suggest that the technology could become capable of self-determination and super intelligence …

Understanding Risk Perception Using Fuzzy Cognitive Maps, Pei Zhang, Antoine J. Jetter

Engineering and Technology Management Faculty Publications and Presentations

When making decision that can have far-researching effects, such as governmental policies or decisions on new technologies, decision-makers use their understanding of the risks that are associated with their choices to guide their decisions. Measuring how people perceive risks can be helpful for understanding and possibly improving the decision-making process. Building on a review of existing methods for investigating risk perceptions, this paper suggests Fuzzy Cognitive Maps (FCM) as a method for investigating differences in risk perception among stakeholders and stakeholder groups. The approach is illustrated with an example of wildfire risk perceptions. Results suggest that FCM can contribute to …

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV and poverty are inextricably intertwined in sub-Saharan Africa. Economic and livelihood intervention strategies have been suggested to help mitigate the adverse economic effects of HIV, but few intervention studies have focused specifically on HIV positive persons. We conducted three pilot studies to assess a livelihood intervention consisting of an initial orientation and loan package of chickens and associated implements to create poultry microenterprises. We enrolled 15 HIV-positive and 22 HIV-negative participants and followed them for up to 18 months. Over the course of follow-up, participants achieved high chicken survival and loan repayment rates. Median monthly income increased, and severe …

Economics Faculty Publications and Presentations

Objective: This initial phase of research lays the foundation for a survey using contingent valuation (CV) and choice experiment (CE) methods. We asked select Portland residents what they care about most in Forest Park, their willingness to pay (WTP) for improving ecosystem services and how they generally think about the value of those goods and services. These results will help us narrow the experimental design of the forthcoming CV/CE study.

Approach: We conducted a focus group in each of Portland’s 5 “quadrants.” We chose each location - Skyline, St. John’s, Cully, Foster-Powell and Hillsdale - based on either its proximity …

Caring For Children With Severe Allergies: Establishing Protocols For Epipens And Other Medical Needs Through Collaborative Practices, William Arthur Parnell, Allison Schnur, Lynn Green

Education Faculty Publications and Presentations

As educators and researchers, throughout our work with young children and families, we authors have cared for children who were prescribed an epinephrine auto-injection device to be used in the case of a severe allergic reaction. However, it wasn't until we actually had to consider using such a device, commonly referred to as an EpiPen-a popular brand of epinephrine auto-injector-that we realized the care plan for these children was unclear. In many ways, the protocols and care-taking processes for managing severe allergies felt unlike those for many other medical concerns due to the instantaneous life threatening nature, immediately needed reactions, …

Gender Bias And The Evaluation Of Players: Voice And Gender In Narrated Gameplay Videos, Robin April Crowell

Dissertations and Theses

This study evaluates perception differences of male and female narrators in video game tutorials. Video games have long been considered a masculine pursuit, and because of this, women have endured unpleasant surroundings and interactions in gaming and related communities. With the proliferation of technologies like Twitch and YouTube gaming, gaming is more communicative than ever, increasing potential for problematic interactions. Recent booms in these technologies emphasize the importance of understanding how varying demographics are perceived, as these perceptions influence interactions, potentially limiting the likelihood of women and others' involvement and interest.

Involvement in technology during youth is associated with interests …

More Than Meets The Eye: Latino Students In A Two-Way Immersion Program And Stereotype Threat, Edgar Ubaldino Solares Vega

Dissertations and Theses

Figures from the 2010 Census indicate that there are 50.5 million Latinos (16% of the total population) living in the United States (US) today. From 2000 to 2010, the Latino population experienced a very rapid growth rate of 43%, which accounted for over half the total population growth. More and more Latino students are entering our public schools and face the reality that 62 years after the Brown V. Board of Education ruling to integrate schools and equalize educational opportunities, schools are more racially and economically segregated and more unequal than they were more than half a century ago. As …

Physical and social characteristics of neighborhoods are important to resident satisfaction for clinical and nonclinical populations. This study draws upon data collected from a sample of 172 individuals with psychiatric disabilities living in 16 supportive housing sites in the Portland, Oregon metropolitan area. Research questions explore the extent to which subjective and objective measures of neighborhood physical and social environments contribute to neighborhood satisfaction for this population. Mixed methods were employed to construct a detailed understanding of the factors that influence satisfaction with one's neighborhood of residence. Predictor variables were neighborhood social climate, neighborhood physical quality, perceptions of safety, crime …

Cheers To Haptic Sensations And Alcohol Consumption: How Glassware Weight Impacts Perceived Intoxication And Positive Emotions, Courtney Szocs, Dipayan Biswas, Adilson Borges

Business Faculty Publications and Presentations

People often consume alcohol as a means of emotional control. More specifically, people frequently consume alcohol to enhance positive feelings (e.g., happiness) and reduce negative feelings (e.g., stress, tension). The results of two field studies and one laboratory study showed that holding the volume of alcohol consumed constant and varying the haptic (i.e., weight) sensations individuals experience during consumption can influence these emotional responses and also perceived intoxication. Specifically, we manipulated haptic weight sensations by varying the weight of the cup/container (e.g., champagne flute) alcohol was consumed from and showed that consuming champagne from lighter (vs. heavier) flutes leads to …

The goals of this research are: a) to develop a platform to collect naturalistic video bicycling data, b) to develop a methodology to integrate video data with other sensors that measure cyclists’ position and comfort levels, and c) to apply the platform and data collection methodology to a real-world route. This research effort has successfully integrated video and sensor data to describe cyclists’ comfort levels along a route. It was found …

Semantic Knowledge Use In Discourse Produced By Individuals With Anomic Aphasia, Stephen Kintz, Heather Harris Wright, Gerasimos Fergadiotis

Speech and Hearing Sciences Faculty Publications and Presentations

Background---Researchers have demonstrated that people with aphasia (PWA) have preserved semantic knowledge (Dell et al., 1997; Jefferies & Lambon Ralph, 2006). However, Antonucci (2014) demonstrated that some PWA have impaired access to certain types of knowledge more than others. Yet, all these studies used single concepts. It has not been demonstrated whether PWA have difficulty accessing certain types of features within a discourse sample.

Aims—The main goals of this study were to determine if semantic knowledge and two category types were used differently within discourse produced by participants with anomic aphasia and healthy controls.

Method & Procedures—Participants …

Filling The Holes: Work Schedulers As Job Crafters Of Employment Practice In Long-Term Health Care, Ellen Ernst Kossek, Matthew M. Piszczek, Kristie L. Mcalpine, Leslie B. Hammer, Lisa Burke

Psychology Faculty Publications and Presentations

Although work schedulers serve an organizational role influencing decisions about balancing conflicting stakeholder interests over schedules and staffing, scheduling has primarily been described as an objective activity or individual job characteristic. The authors use the lens of job crafting to examine how schedulers in 26 health care facilities enact their roles as they “fill holes” to schedule workers. Qualitative analysis of interview data suggests that schedulers expand their formal scope and influence to meet their interpretations of how to manage stakeholders (employers, workers, and patients). The authors analyze variations in the extent of job crafting (cognitive, physical, relational) to broaden …

Information Literacy In The First Year Of Higher Education: Faculty Expectations And Student Practices, Meredith Esther Michaud

Dissertations and Theses

Information literacy is widely acknowledged as important for student success in higher education. Information literacy is the ability to sort through a large amount of available information, decide what is useful and believable, and apply it in an effective and ethical way. Faculty members have expectations regarding information literacy for students in the first year of college, while students have information literacy practices that may or may not match those expectations. In my study, I examined the alignment of faculty member information literacy expectations and student information literacy practices, focusing on freshman students and faculty members who teach freshman students …

The Mediating Effects Of Lmx On The Relationship Between Supervisor And Employee Age Differences, Satisfaction, And Retirement Intentions, Amy Christine Pytlovany

Dissertations and Theses

Increasing age heterogeneity within organizations is pressing researchers to better understand the effects of a multigenerational workforce, teams, and dyads. In response to this, the present research aimed to investigate the effect of employee and supervisor age (in)congruence in relation to job and life satisfaction, as well as retirement intentions, all mediated by leader-member exchange (LMX), using a time-lagged design. Two different theoretical foundations were investigated. Based on the relational demography literature, better outcomes were expected to be associated with age similarity. Theories about implicit expectations relating age and social role guided hypotheses suggesting that beyond just similarity or difference, …

Teacher Mindfulness In The Middle School Classroom: Reliability And Validity Of A New Scale, Nicolette Paige Rickert

Dissertations and Theses

Despite significant growth in research examining the effects of mindfulness interventions on teachers (Roeser, 2014), studies have mainly relied on self-reports of teacher mindfulness and have not examined observable behavioral manifestations of teacher mindfulness in the classroom. Due to possible biases in self-report measures (Dotterer & Lowe, 2011), as well as the need for a greater range of assessments of the effects of mindfulness trainings on teachers, the current study sought to create a new measure of teacher mindfulness in the classroom from three sources of information: teacher self-reports of their own behavior in the classroom, student perceptions of their …

Do Forest Commons Contribute To International Environmental Initiatives? A Socio-Ecological Analysis Of Nepalese Forest Commons In View Of Redd+, Harisharan Luintel

Dissertations and Theses

Forests in developing countries have the potential to contribute to global efforts to mitigate climate change, promote biodiversity and support the livelihoods of rural, local people. Approximately one-fourth of such forests are under the control of local communities, which primarily manage forests for subsistence and to meet their livelihood needs. The trend of bottom-up community control is increasing through the adoption of decentralization reforms over the last 40 years. In contrast, the United Nations has introduced the top-down program, Reducing Emissions from Deforestation and Forest Degradation (REDD+) for the conservation and enhancement of forest carbon and the sustainable management of …

Bridging The Worlds Of Home And School: A Study Of The Relational Worlds Of First-Generation Students In A School Of Social Work, Miranda Cunningham

Dissertations and Theses

Much scholarship on first-generation students has focused on their academic and social integration in college (Collier & Morgan, 2008; Lowery-Hart & Pacheco, 2011; Stuber, 2011). Little is known about the experiences of first-generation students in schools of social work. In this research I've expanded the focus beyond students' experiences of academic integration to explore how first-generation students in a school of social work describe their relational worlds and the implications for professional socialization.

Informed by Standpoint Feminism and Postmodern/Post structural Feminism, I conducted focus groups with 19 students in two undergraduate programs and one graduate program in a school of …

Social Support And Depression Symptomatology Post Injury In Division 1 Athletes, Alyssa Catherine Tiedens

Dissertations and Theses

The way in which an athlete responds to the injury--emotionally, behaviorally, and cognitively--can significantly affect the athlete's mental health in a negative way if not handled appropriately. There are different forms of social support that are known to be helpful with coping during specific stages of injury. The purpose of this study was to examine the relationship between perceived levels of social support and depression symptomatology post injury in Division 1 collegiate athletes at Portland State University (PSU).

Participants were PSU student athletes (n=115). Variables: social support amount (SSQN), social support satisfaction (SSQS), and depression symptomatology (CESD-R) score. Selected injured …

Incorporating Etds In The Ir, One Department At A Time, Kristen Hoffman

Northwest IR User Group

How do you add student work to an IR when there is no centralized graduate school? At Seattle Pacific University, each department or school sets their own policy and has their own unique workflow, which has both challenges and benefits. Kristen worked with five individual departments to establish workflow solutions; consider if one of these options may work for you as you incorporate student work.

An Interpretive Phenomenological Analysis Of Long-Term Mentoring Relationships From The Youth Perspective, Kevin Richard Jones

Dissertations and Theses

When mentoring programs are well-designed and well-implemented, young people can experience positive gains in a number of social, emotional, behavioral, and educational areas. While some of the processes underlying mentoring relationships have been explored, the voices and perspectives of participants themselves have thus far been largely excluded from the mentoring literature. The lack of participant voice in mentoring research suggests that an important source of empirical and interpretive information is unavailable to the field in the process of designing, implementing, and researching mentoring programs. This study used interpretive phenomenological analysis (IPA) to explore how youth participants in the Friends of …
