Reconstructability Analysis Of The Predictors Of Physical Functioning Status In Older Americans By Race And Ethnicity, Amanuel Melekin, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper demonstrates the use of reconstructability analysis to examine race/ethnic differences in physical functioning status among older Americans. Reconstructability analysis is an information theory and graph theory method which has been successfully used in multivariate data modeling. The health and retirement study data from 2004 are used for this demonstration. Out of eighteen independent variables included, seven variables appeared in the best models selected. Uncertainty reductions in physical functioning status were substantial across the models but the magnitudes and predictive variables varied slightly by race/ethnicity. Examination of the model probability distributions indicated that composite independent variable states of overlapping …

School of Social Work Faculty Publications and Presentations

There is little work published about predictors of specific trajectory types of distress in refugees of war during early resettlement in a host country. Data about distress (Refugee Health Screener—15 (RHS-15)) and possible predictors of distress were collected at the domestic medical examination (T1) within 90 days of arrival and the civil surgeon examination (T2) 11–16 months after T1 for refugee groups from three countries (COU). Descriptive, correlative, analyses of variance, and regression techniques were used to determine trajectory type and their predictors. A higher percentage (7.3%) were distressed at T2 than at T1. By group, the Bhutanese became more …

Blacks In Oregon, Darrell Millner

Black Studies Faculty Publications and Presentations

Periodically, newspaper or magazine articles appear proclaiming amazement at how white the population of Oregon and the City of Portland is compared to other parts of the country. It is not possible to argue with the figures—in 2017, there were an estimated 91,000 Blacks in Oregon, about 2 percent of the population—but it is a profound mistake to think that these stories and statistics tell the story of the state's racial past. In fact, issues of race and the status and circumstances of Black life in Oregon are central to understanding the history of the state, and perhaps its future …

Outcomes Of Telepractice Speech Therapy For An Adult Who Covertly Stutters: A Case Study, Megann Mcgill, Patrizha A. Schroth

Both educators, who center relationships and social justice in their teaching, reflect on what they learned and identify and analyze three tensions experienced by the K-12 teacher: concerns about coming across as too political, responding to parent and caregiver reservations about teaching SEL, and grappling with teachers’ emotions in the classroom. Main takeaways are discussed, including the value of partnership between teacher educators and their former students in the development of teaching …

Regenerating Teacher Education Programs With Indigenous Knowledge In Idaho, Vanessa Anthony-Stevens, Johanna Jones, Victor Begay

Northwest Journal of Teacher Education

This paper examines movements in educational policy to address the inequitable schooling experiences of American Indian youth. We look specifically at recent policy revisions to teacher education standards in the state of Idaho which intend to address preservice teachers’ knowledge and dispositions to build understanding and respect for Indigenous ways of knowing and tribal sovereignty in classrooms and schools. We argue that critical, culturally based teacher training programs can prepare competent, equity conscious teachers to address the unique challenges of schools, especially those serving Indigenous youth. Such frameworks are vital acts of social justice education which benefit all students.

Racial Gatekeeping In Country & Hip-Hop Music, Cervanté Pope

University Honors Theses

In mass communication, gatekeeping refers to how information is edited, shaped and controlled in efforts to construct a "social reality." One way it presents itself is in regard to racial inclusion and equality, and despite the headway we’ve seemingly made as a society, we are still lightyears away from where we need to be. Because of this, the concept of cultural property has become even more paramount, as a means for keeping one's cultural history and identity-preserved. Blacks and whites similarly attempt to protect or preserve facets of their culture they feel belong to them. What’s different for both of …

Revisiting The Role Of Physicians In Assisted Living And Residential Care Settings, Sarah Dys, Lindsey Smith, Ozcan Tunalilar, Paula C. Carder

Institute on Aging Publications

As the United States population ages, a higher share of adults is likely to use long-term services and supports. This change increases physicians’ need for information about assisted living and residential care (AL/RC) settings, which provide supportive care and housing to older adults. Unlike skilled nursing facilities, states regulate AL/RC settings through varying licensure requirements enforced by state agencies, resulting in differences in the availability of medical and nursing services. Where some settings provide limited skilled nursing care, in others, residents rely on resident care coordinators, or their own physicians to oversee chronic conditions, medications, and treatments. The following narrative …

Human Energy In The Workplace: An Investigation Of Daily Energy Management Strategies, Job Stressors And Employee Outcomes, Morgan Rose Taylor

Dissertations and Theses

Recent research has pointed to the benefits associated with the use of work-related energy management strategies for employee outcomes. Using the Conservation of Resources Theory and the Challenge and Hindrance Stressor Framework, the current study extends the energy management literature by examining day-level relationships between work-related energy management strategies (e.g., organizing, meaning-making, and prosocial strategies) and employee outcomes, namely, goal progress, work engagement, and relational energy respectively. Further, challenge and hindrance stressors are tested as day-level moderators of these relationships. Using experience sampling methods across 10 workdays, results showed that day-level organizing strategy use was related to higher goal progress …

Stopped Listening: Experiences Of Higher Education Refugee-Background Learners, Peggy Lynn Maclsaac, Staci B. Martin, Wilson Kubwayo, Chablue Wah, Salome Nanyenga

School of Social Work Faculty Publications and Presentations

This paper discusses the academic agency of refugee-background individuals who have resettled to the United States of America and the responsibility of higher education to value refugee-background learners as knowledge creators. Contrary to deficit thinking that views learners as unable to succeed due to their refugee background, this study explores how their experiences demonstrate their multiple capacities to succeed in higher education. The essence of these experiences is presented using self-reflexive collaborative speaking and writing inquiry. Three main themes drawn from the results were the capacities of refugee-background learners to adapt cultures, maintain multiple social connections, and exercise agency.

Achieving High Reliability Organizations Using Fuzzy Cognitive Maps - The Case Of Offshore Oil And Gas, Ahmed A. Alibage

Dissertations and Theses

The safety culture of so-called high-reliability organizations (HROs) encompasses values, routines, and work processes that allow an organization to prevent mistakes and quickly bounce back if unexpected events occur. It is said to provide a model for improving organizational resilience in the offshore oil and gas industry, where small errors can grow into accidents with devastating environmental, social, and economic impacts. To date, such a transfer of successful practices is impeded by a lack of system perspective that would allow researchers and practitioners to fully understand the safety dynamics in HROs, adjust them to the unique setting of offshore oil …

Identification Of Degradation Products Formed From Glycerol And Terpenes In Aromatherapy Vaporizers, Alisha Ortiz

Degradation chemistry has been widely studied to assess the safety of aerosols in many fields. The study herein investigates the degradation products formed from MONQ personal aromatherapy devices- a new non-nicotine aromatherapy vape pen device on the market. These pens are marketed to alleviate symptoms of an unrecognized medical syndrome called “terpene deficiency”. These pens contain a glycerin (GL), or glycerol (VG), base and a blend of terpene-rich essential oils. Previous studies have investigated the degradation of both VG and terpenes and have shown that concerning compounds are released in the gas phase, including benzene, benzaldehyde, methacrolein and methyl vinyl …

Aligning Food Environments With Institutional Values: A Mixed Methods Study Of Oregon Health Care Organizations, Elizaveta Walker

Dissertations and Theses

A major driver of the obesity epidemic is obesogenic food environments, characterized by nutrient-poor and energy-dense foods that saturate the collective physical, economic and sociocultural conditions that influence nutritional status. Food environments in organizations such as hospitals and public health agencies warrant special consideration given their health-focused mission. Improving food environments within health care settings has been highlighted by the Centers for Disease Control and Prevention (CDC) as one of seven key strategies to prevent obesity. However, most of the refereed literature examining healthy food environment policies (HFEPs) within hospitals focuses on the inpatient dietary environment, leaving a paucity of …

Juveniles In The Interrogation Room: Defense Attorneys As A Protective Factor, Caitlin N. August, Kelsey S. Henderson

Criminology and Criminal Justice Faculty Publications and Presentations

Juveniles are more susceptible in the interrogation room than adults, due to a host of vulnerabilities that put them at risk. Scholars have suggested that requiring the presence of a defense attorney during interrogations can protect juveniles from making an unintelligent waiver; variations of this type of policy have been mandated in some states across the United States (e.g., Illinois and California). The current study takes an exploratory, qualitative approach to examine how defense attorneys may act as a protective factor in the interrogation room. We interviewed 19 juvenile defenders using a semi-structured interview method; questions focused on experiences in …

“We Were Queens.” Listening To Kānaka Maoli Perspectives On Historical And On-Going Losses In Hawai’I, Antonia R.G. Alvarez, Val. Kanuha, Maxine K.L. Anderson, Cathy Kapua, Kris Bifulco

School of Social Work Faculty Publications and Presentations

This study examines a historical trauma theory-informed framework to remember Kānaka Maoli (Native Hawaiian) and lesbian, gay, bisexual, transgender, queer, and/or māhū (LGBTQM) experiences of colonization in Hawai`i. Kānaka Maoli people and LGBTQM Kānaka Maoli face health issues disproportionately when compared with racial and ethnic minorities in Hawai’i, and to the United States as a whole. Applying learnings from historical trauma theorists, health risks are examined as social and community-level responses to colonial oppressions. Through the crossover implementation of the Historical Loss Scale (HLS), this study makes connections between historical losses survived by Kānaka Maoli and mental health. Specifically, this …

Critical Thinking In A Service-Learning Course: Impacts Of Information Literacy Instruction, Heather R. Kennedy, Anne Marie H. Gruber

Communications in Information Literacy

It is well demonstrated that service-learning positively impacts a variety of student outcomes. However, methodological limitations have contributed to a lack of clear understanding of the mechanisms through which these effects occur. Additionally, little research has connected information literacy instruction explicitly with outcomes in service-learning courses. The present study used a pre-/post-test design to investigate cognitive outcomes, including critical thinking, using the Problem-Solving Analysis Protocol (P-SAP). Fifty-nine students from an undergraduate family services course participated. Results highlight the importance of library instruction to students’ critical thinking skills and suggest implications for collaborations between discipline faculty and library faculty in service-learning …
