Financial Metrics As Predictors Of Financial Vulnerability And Nonprofit Failure, Yossi Haimberg

Dissertations and Theses

Studying nonprofit's risk factors for financial vulnerability and possible demise is important because of the negative social consequences for both the failed organization and its stockholders. Financial vulnerability is a concern shared by all nonprofit's stakeholders as poor financial health affects nonprofit's ability to fulfill its mission, sustain its operations, and in many cases may result in a nonprofit demise. Advance knowledge on financial vulnerability has significant implications for nonprofit's leaders to develop corrective strategies to prevent failure.

Nonprofit scholars such as Tuckman and Chang, Greenlee, Hager, and Searing have contributed notable benchmarks in the field of nonprofit vulnerability, by …

Urban Beavers At The Crossroads: How Ecological Knowledge, Sociodemographic, And Spatial Context Shape Public Perception And Coexistence Preferences, Matthew Guziejka

Dissertations and Theses

Urban beavers demonstrate synurbization by adapting to urban environments, offering ecological benefits such as biodiversity enhancement and flood mitigation, while also occasionally conflicting with infrastructure. This study examines how ecological knowledge, sociodemographics, and spatial context influence public perceptions and management preferences for urban beavers in the Tualatin River watershed, Oregon.

A voluntary survey of 176 participants from peri-urban areas assessed demographic characteristics, ecological knowledge, and attitudes toward management approaches. Spatial factors, such as proximity to watercourses and green spaces, were also analyzed. Logistic regression analyses were used to explore relationships between these factors and management preferences. Political orientation was significantly …

Color Aberrations In Seven Bird Species In Costa Rica, Lucia Isabel Lopez, Jose Manuel Mora, Adrian Alvarado Rivera

Biology Faculty Publications and Presentations

Although there are 935 species of birds in Costa Rica, scientific reports of pigmentation abnormalities in this group are limited. Nevertheless, several cases have been recently documented, including Leucism, Ino mutation, Progressive Graying, Dilution, and two unusual color aberrations in a toucan and a motmot. Here we describe seven cases of color aberrations observed over a period of five years in native birds of Costa Rica. An Eastern Wood-Pewee Contopus virens and a White-collared Manakin manacus candei were Brown. A Scintillant Hummingbird Selasphorus scintilla and a Talamanca Hummingbird, Eugenes spectabilis, also showed a Brown mutation, however, these two cases may …

Working Paper No. 88, Algorithms And Thorstein Veblen’S ‘Machine Process’, Eunji Jang

Working Papers in Economics

This inquiry seeks to establish that the ‘machine process’ which Thorstein Veblen introduced into the Economics literature back in 1904, exhibits similarities to algorithms that are readily found in contemporary times--more than one hundred years on. In The Theory of Business Enterprise [1904] (2005), Veblen defines the machine process as a system that prioritizes efficiency, standardization, and automation. Relatedly, this inquiry argues that algorithms are based upon similar principles and exhibit similar tendencies that yield similar outcomes. Additionally, this inquiry explores the institutional role of algorithms, elaborating upon how their increasing prevalence and solidification might serve to enhance efficiency in …

Neural Visual Synthesis For Graphics, 4d Gaussians And Videos, Zhan Li

Dissertations and Theses

Efficient visual synthesis has played an indirect yet important role in the development of neural networks. Graphics processing units (GPUs) were initially designed for visual synthesis tasks such as rendering graphics. However, their parallel computing capabilities later made GPUs the ideal hardware for training neural networks. Since neural networks have greatly benefited from GPUs, a compelling question arises: How can neural networks, in turn, improve efficient visual synthesis?

Existing visual synthesis methods still require improvement for higher efficiency. For example, Monte Carlo rendering takes over 15 minutes to generate a megapixel frame at a high-quality setting on a GPU, as …

Influence Of Inselbergs On Bat Diversity In Afrotropical Ecosystems, Amanda Lee Grunwald

Dissertations and Theses

Humans are altering biological communities on local to global scales, driving profound changes in biodiversity and ecosystem functioning. However, significant gaps and biases in biodiversity data hinder our understanding of ecosystem interactions, making it challenging to develop effective, data-driven policies to protect remaining biodiversity. Bats, the second most species-rich groups of mammals, have a global distribution, and perform a broad array of vital ecosystem functions. Their diversity peaks in the tropics, where they often constitute more than 50% of mammal species diversity. The Afrotropics host substantial bat diversity, yet have historically been perceived as having lower species richness compared to …

Combining Passive And Active Ultrasonic Stress Wave Monitoring For The Characterization Of The Early-Age Properties Of A Uhpfrc Beam, Numa Bertola, Thomas Schumacher, Ernst Niederleithinger, Eugen Bruhwiler

Civil and Environmental Engineering Faculty Publications and Presentations

This article focuses on the characterization of the early-age properties of Ultra-High-Performance Fiber-Reinforced Cementitious Composite (UHPFRC), which is becoming popular for designing lightweight and durable structures. Due to the large proportion of cement in the mix, the hardening of UHPFRC is significantly faster than conventional concrete. Therefore, the development of UHPFRC properties, such as the elastic modulus, is difficult to monitor as it happens while elements are within the formwork. For this reason, the hydration process of UHPFRC elements is not fully understood yet. A combined passive (or acoustic emission) and active ultrasonic stress wave monitoring approach has the potential …

Mindful Wonderment: Using Focus Groups To Frame Social Justice, Rolla Lewis, Susan Davis Lenski, Swapna Mukhopadhyay, Chris Taylor Cartwright

Curriculum and Instruction Faculty Publications and Presentations

In the recent past many professional schools of education in the United States have embraced social justice as central to their mission in preparing teachers, counselors, and administrators to work in preK-16 settings. This article documents our initial inquiry guided by mindful wonderment into an effort to frame social justice as a collective collaboration involving support staff, faculty, and administrators within a graduate school of education. A series of focus groups made up of members of a school of education considered the commitment to social justice not only for its preK-16 candidates but also for transforming the environment and culture …

Layout-Aware Quantum Circuitry And Algorithmic Extensions To Grover's Algorithm, Ali Al-Bayaty

Dissertations and Theses

Lov K. Grover introduced, in 1996, Grover's algorithm as a quantum search algorithm to find all solutions for quantum oracles representing classical problems. My research observed that the Grover diffusion operator of Grover's algorithm gives wrong solutions when Boolean oracles are designed in some logical structures. Therefore, I invented the new "controlled-diffusion operator" for Boolean oracles as a new approach for Grover's algorithm that always correctly solves the problem of Grover's algorithm.

Another important problem in quantum computing is designing reliable and cost-effective quantum gates using reversible binary logic. In classical logic design, the stage of logic design can be …

Organizational Supports For Promoting Evidence Use In Private Child Welfare Agencies, Crystal Collins-Camargo, Emmeline Chuang, Bowen Mcbeath

School of Social Work Faculty Publications and Presentations

There is minimal literature about the organizational supports that private child welfare agencies have in place to pursue positive outcomes for the children and families they serve. This study drew upon the perspectives of 27 senior managers of fourteen nonprofit child and family serving agencies in six U.S. states to examine the extent to which agencies employed organizational supports for evidence use. We identified four types of organizational supports: technical and knowledge management infrastructure, leadership and strategic alignment, and linkage and exchange efforts. Managers described whether and how they used these supports to facilitate evidence-informed decision-making and practice. Managers also …

Model Explanations For Gender And Ethnicity Bias Mitigation In Ai-Generated Narratives, Martha Otisi Dimgba

Dissertations and Theses

Large Language Models (LLMs) are increasingly utilized in diverse applications, ranging from professional content creation to decision-making systems. However, their outputs often amplify the biases present in their training data, perpetuating stereotypes and reinforcing societal inequities, particularly regarding gender and ethnicity. Such biases can cause tangible harm, especially for underrepresented groups, and require awareness and effective mitigation strategies.

This work explores gender and ethnicity representation in narratives created by generative AI describing 25 occupational fields defined by the U.S. Bureau of Labor Statistics. We examine three large language models (LLMs)--Llama 3.1 70B Instruct, Claude 3.5 Sonnet, and GPT 4.0 Turbo. …

Culturable Microbial Communities In Root Nodules Of Red Alder (Alnus Rubra Bong.) And Scotch Broom (Cytisus Scoparius L.): Patterns Of Diversity And Composition, Felisha (Fay) Rene Pooler

Dissertations and Theses

Endophytes are a hyper diverse group of bacterial or fungal organisms residing within plant tissues without causing visible symptoms of disease. While their overall diversity and ecological functions are not well-understood, some endophytes can provide a range of important benefits to their host such as enhanced growth and increased tolerance to environmental stress. Nitrogen-fixing bacteria residing within nodules--specialized structures on the roots of legumes and actinorhizal plants--play an integral role in the plant microbiome by facilitating nitrogen availability in nutrient-poor environments. Remarkably, the patterns of diversity including both bacterial and fungal endophytes in root nodules are virtually known, except in …

Towards A Global Understanding Of Tree Mortality, Andres Holz, International Tree Mortality Network

Geography Faculty Publications and Presentations

Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground-based long-term forest monitoring with large-scale remote sensing. We surveyed the metadata from 466 865 forest monitoring plots across 89 countries and five continents using questionnaires and discuss the potential to use these to estimate tree mortality trends globally. Our survey shows that the area monitored has increased steadily since 1960, but we also identify many regions with limited ground-based information on tree …

Plural Water Narratives: An Environmental Justice Lens On A Systematic Review Of Q-Methodology Water Research, Melissa Haeffner, Alida Cantor, Janet Cowal, Andrea Bryant, Darius Mani Yaw, Kinna Je Palacios, Daniela Serna, Bryce Sprauer, Abigail Tran-Gruver

Environmental Science and Management Faculty Publications and Presentations

Environmental justice research has shown that people's experiences and perceptions of water differ because systematic inequalities shape the extent to which people access clean water and are exposed to water hazards. Q‐methodology is one technique that has been used to aggregate multifaceted subjective narratives and understand different perspectives on a topic. In this paper, we systematically review 77 case study articles applying Q‐methodology to water‐related topics, to inventory how people perceive their relationships with water. We create a classification system based on environmental justice theory to examine (1) distributive justice issues around alternative water sources and agricultural and urban water …

"Our Vision Is That Black Mothers And Birthing People, Fathers, And Partners Are Safe, Honored, And Respected Throughout Pregnancy And Parenthood": Black Birth Workers' Agenda For Black Maternal Health In Oregon, Sarah Marguerite Applin

University Honors Theses

Black women and Birthing People (BWBP) face disproportionate rates of mortality within the United States healthcare system. BWBP are three times more likely to suffer a pregnancy-related death than White women. Therefore, addressing and consulting with BWBP about the birthing experience that BWBP sustains when they are bearing children is imperative. The inclusion and application of this key knowledge and understanding should be emphasized and at the root of further development toward reproductive justice. This participatory story was led by Dr. Roberta Hunte. Interviews and focus groups with Black birth workers, birthing people, and public health professionals were conducted in …

Publishing And The Literary Agent, Rachel Noorda

English Faculty Publications and Presentations

Literary agents are an under researched and comparatively recent feature of international book publishing. This chapter defines literary agents in comparison to other international book publishing intermediaries (like foreign rights agents and literary scouts) and maps the history and roles of the literary agent in Europe and Anglo-America from the nineteenth century to the present. Agents are pushed and pulled by various dichotomies in the industry: center vs periphery, culture vs commerce, local vs global. Over time, literary agents have evolved from brokers to author advocates and informal to professionalized, enabled to flourish and multiply through international copyright coordination and …

OHSU-PSU School of Public Health Faculty Publications and Presentations

Objective: Public health approaches for addressing diet-related health in the United States (US) include nutrition incentive (NI) and produce prescription (PPR) projects. These projects, funded through the US Department of Agriculture Gus Schumacher Nutrition Incentive Program (GusNIP), aim to support intake of fruits and vegetables through healthy food incentives. Measuring GusNIP impact is vital to assessing the ability of incentives to improve public health nutrition outcomes across populations. Shared measures used across GusNIP projects assess fruit and vegetable intake, food security, demographics, among other variables, through a participant survey. This study explored challenges and opportunities to support evaluation across GusNIP. …

The Effects Of Imidacloprid And Polyester Microfibers On The Larval Development Of The Endangered Sunflower Star, Alexandra G. Tissot, Elise F. Granek, Fiona Curliss, Augustin Kalytiak-Davis, Jason Hodin, Michelle L. Hladik

Environmental Science and Management Faculty Publications and Presentations

Sea star wasting syndrome has affected numerous species of sea star, with populations of Pycnopodia helianthoides (Brandt, 1835) left most at risk. As their populations are struggling to recover, it is important to gain a better understanding of the impacts that the multiple stressors in their habitats can have on their populations. Contaminant stressors in particular are of increasing importance, because aquatic organisms can be exposed to a dynamic range of contaminants from nearby anthropogenic activity that may affect their future recovery efforts. This study is the first to quantify the effects of contaminant stressors on the larvae of P. …

The Dementia Care Partner Hub: An Innovative Approach To Addressing Unmet Social And Health Needs, Sherril Gelmon, Jenn Reed, Walter D. Dawson

OHSU-PSU School of Public Health Faculty Publications and Presentations

The well‐being of care partners of people living with dementia, who are family, friends, or neighbors and often unpaid, is often not addressed explicitly in clinical dementia care. Care partners, especially those from systematically marginalized communities, experience substantial unmet social and behavioral needs. We reviewed role model programs and conducted focus groups and interviews with care partners and representatives of community organizations and government agencies. We developed the concept of a Dementia Care Partner Hub as a “one‐stop shop” to connect dementia care partners and service providers with information and resources, meeting a need that is not currently addressed in …

Investigating Environmental Controls On Temperature Dynamics In An Urban Stream, Matthew Cullen Yates

Dissertations and Theses

Water temperature is a critical environmental variable influencing aquatic ecosystems. This study investigated the factors controlling stream temperature and thermal stratification in Rock Creek (RC) and Bethany Lake, an urbanized watershed featuring an in-line irrigation pond and buried wastewater infrastructure. Previous research suggested that subsurface water flow might drive temperature shifts in Rock Creek during summer periods when flow from Bethany Lake ceases. From 2023 to 2024, continuous temperature and stage monitoring, combined with statistical methods including principal component analysis and random forest regression, were used to evaluate seasonal temperature dynamics and their controlling factors. Results confirmed that seasonal reversals …

All The Lonely People: An Integrated Review And Research Agenda On Work And Loneliness, Julie M. Mccarthy, Berrin Erdogan, Talya Bauer, Selin Kudret, Emily Campion

Business Faculty Publications and Presentations

Decades of studies spanning multiple disciplines have provided insight into the critical role of loneliness in work contexts. In spite of this extensive research, a comprehensive review of loneliness and work remains absent. To address this gap, we conducted a multidisciplinary review of relevant theory and research and identified 213 articles reporting on 233 empirical studies from management, organizational psychology, sociology, medicine, and other domains to uncover why people feel lonely, how different features of work can contribute to feelings of loneliness, and the implications of employee loneliness for organizational settings. This enabled a critical examination of the distinct conceptualizations …

A Critical Appraisal Of Poverty In The Context Of Nature-Based Communities: Selected Cases From The Philippines, Carla Edith Gonzales Jimena

Dissertations and Theses

The Philippines is considered one of the wealthiest countries in both Southeast Asia and the world when measured by biodiversity, mineral resources and natural resources. It is also one of the most highly mineralized countries on earth. However, despite these natural endowments, when measured by established economic and human development indices the Philippines remains poor. Using critical perspectives derived from Marxist tradition, William Chambliss' theory of law and its dialectical nature, Immanuel Wallerstein's World Systems Theory, and Fred Block's structural mechanism of the state, this study aimed to critically appraise the persistence of poverty in nature-based communities in the Philippines. …

Integrating The Interconnections Between Groundwater And Land Surface Processes Through The Coupled Nasa Land Information System And Parflow Environment, Fadji Z. Maina, Dan Rosen, Peyman Abbaszadeh, Chen Yang, Sujay V. Kumar, Matthew Rodell, Reed Maxwell

Civil and Environmental Engineering Faculty Publications and Presentations

Understanding the interactions between the atmosphere, the land, and the subsurface is fundamental to hydrology and is critical for a better assessment of the impacts of climate change and human management on hydrological systems. However, many land surface models simplify the subsurface hydrology and thereby these interactions. In this study, we couple the land surface model Noah‐MP included in the NASA Land Information System (LIS) with the integrated hydrologic model ParFlow (ParFlow‐LIS) using the Earth System Modeling Framework (ESMF) and the National United Operational Prediction Capability (NUOPC). This coupling improves the simulation of water and energy cycle processes by adding …
