Silos In Higher Education Institutions: Shifting From Organizational Phenomena To A Practical Framework For Equitable Decision-Making, Mandi Sue Mizuta

Dissertations and Theses

As higher education has evolved, administrative and support functions have become more stratified and specialized, creating institutions with complex and compartmentalized organizational structures known as silos. These silos have a detrimental impact on institutions, employees, and ultimately the student stakeholders that they serve. Silos within higher education administration support services are readily acknowledged anecdotally; however, robust research to describe this phenomenon and actionable resources to address it are lacking. This multi-paper dissertation explores the theoretical implications and practical applications for using collaborative, intentional approaches to address what is argued to be at its core is a matter of equity. The …

Thermophysical Properties Of Inorganic Phase-Change Materials Based On Mncl2·4h2o, Kyung-Eun Min, Jae-Won Jang, Jun-Ki Kim, Chien Wern, Sung Yi

Mechanical and Materials Engineering Faculty Publications and Presentations

Manganese (II) chloride tetrahydrate, classified as an inorganic phase-change material (PCM), can be used as a thermal energy storage material, saving and releasing thermal energy during its phase transitions. In this study, thermophysical properties, such as phase change temperatures, latent heat, and thermal conductivities, of four types of MnCl₂·4H₂O PCMs were investigated under single and dual phases (liquid-, solid-, and dual-phase PCMs) using differential scanning calorimetry (DSC) and a heat flow meter. PCMs with a liquid or dual phases exhibited superheating issues, and their melting temperatures were 7 to 10 °C higher than the reference melting …

Erasure Through Engagement: The Community Resettlement Of Isle De Jean Charles, Meghan Elizabeth Sullivan

Dissertations and Theses

The State of Louisiana and the national media have claimed that the community resettlement of Isle de Jean Charles (IDJC) is an example of a 'model resettlement' for communities experiencing the impacts of climate change. At the outset, the project was advocated and led by the tribal leadership of the Isle de Jean Charles Band of the Biloxi-Chitimacha-Choctaw Tribe. Although, through the course of the resettlement the supposed partnership between the State of Louisiana and the Tribe has dissolved. This study seeks to provide a robust and in-depth understanding of the planning and implementation process of the IDJC resettlement to …

Analytic Solution Of 1d Diffusion-Convection Equation With Varying Boundary Conditions, Małgorzata B. Glinowiecka-Cox

University Honors Theses

A diffusion-convection equation is a partial differential equation featuring two important physical processes. In this paper, we establish the theory of solving a 1D diffusion-convection equation, subject to homogeneous Dirichlet, Robin, or Neumann boundary conditions and a general initial condition. Firstly, we transform the diffusion-convection equation into a pure diffusion equation. Secondly, using a separation of variables technique, we obtain a general solution formula for each boundary type case, subject to transformed boundary and initial conditions. While eigenvalues in the cases of Dirichlet and Neumann boundary conditions can be constructed easily, the Robin boundary condition necessitates solving a transcendental algebraic …

Policing By Proxy: Interrogating Big Tech's Role In Law Enforcement, Claire Elizabeth

University Honors Theses

Predictive policing, sometimes referred to as data-driven or actuarial policing, is a method of policing that uses a risk-based approach to law enforcement. For-profit technology companies market proprietary risk assessment algorithms to law enforcement organizations as tools meant to proactively mitigate crime. Using data collected from a vast array of sources, both personal and public, police are able to "predict" the likelihood of criminal activity in a given area using these algorithms. Proponents claim that risk assessment tools have the potential to fight crime with unbiased accuracy and speed by predicting when, where, and whom to police by relying on …

Working Paper No. 65, On Debt, Enclosure And Witchcraft, Anonymous

Working Papers in Economics

This inquiry seeks to establish that the process of commons-enclosure taking place in 14th-16th century Europe also required an “enclosure” of the female body, which was carried out by introducing radically novel conceptions of debt. The dual processes of bodily dispossession and debt imposition acted as a single force which is paradoxically the origin and effect of capitalist accumulation. This process began in Europe during the period of “transition” between feudalism and capitalism but has remained an essential component of capitalist accumulation through to globalization in contemporary times. To support this thesis, this inquiry considers the evolution of debt; the …

Autofluorescence Microscopy: Identifying Bacterial Signals On Rock Samples, Noel Case

University Honors Theses

One common method for identifying microbes present in fluid and non-fluid samples is fluorescent dye staining, in which samples are stained with a fluorophore - a molecule excited by an external light source that re-emits energy as higher-wavelength light. The excitation wavelength used greatly impacts the observability of microbes in the resulting fluorescence images, and deep ultraviolet excitation (200-280 nm) seems to provide the highest signal-to-noise ratio of any excitation range. By inoculating rock samples (gypsum and marble) with B. subtilis, staining with SYTO 9, Acridine Orange and FM 1-43 dyes, and imaging with deep UV (275 nm), near …

Climate And Intraspecific Geographic Variation Of Nests And Eggs In The Eastern Kingbird Tyrannus Tyrannus, Samantha Marie Gillette

Dissertations and Theses

The reproductive success of birds is ultimately driven by the traits of nests, eggs, and incubation behavior and the interactions among them. Avian reproduction varies on large geographic scales, most prominently between tropic- vs. temperate-breeding species, but also on finer scales, such as along latitudinal and elevational geographic gradients. However, despite the importance of eggs and nests, how their traits vary geographically in response to differences in regional climate remains understudied.

We studied Eastern Kingbirds (Tyrannus tyrannus), which have been previously demonstrated to alter incubation length in response to local climate conditions. Our study sites, Kansas (KS), New …

"There Is Great And Awful Immorality In This Place": Environment, Character, And Reform In South Wales, 1847-1919, Allison Kirkpatrick

University Honors Theses

In the second half of the nineteenth century and beginning of the twentieth, sanitarians and reformers in Britain undertook a wide range of public health campaigns aimed at improving the conditions of the industrialized urban environment. Some turned their attention to south Wales, where the coal industry had spurred rapid urban growth and transformed the region into one of Britain's industrial centers. The negative effects of this transition were most acutely felt in working-class communities in the south Wales coalfield, where a near-complete lack of urban planning had left a legacy of overcrowding, nonexistent or inadequate drainage and sewage systems, …

Assessing The Impact Of Three Intersection Treatments In A Bicycling Simulator, Logan Scott-Deeter, David Hurwitz, Brendan Russo, Edward Smaglik, Sirisha Kothuri

Civil and Environmental Engineering Faculty Publications and Presentations

Bicyclist safety at urban intersections is a critical element for encouraging an increase in bicycle commuting. With cyclist injury and fatality rates rising due to collisions with vehicles at signalized intersections, increasing the safety of riders continues to be an important consideration when promoting this mode of transportation. Previous research has addressed crash causality and helped to develop several roadway treatments to improve bicyclist safety, but little has been done to compare and contrast the benefits of the various treatment types. This bicycling simulator study examined the impacts of three different intersection treatments (i.e., bike box, mixing zone, and bicycle …

Transportation Mode Choice Behavior In The Era Of Autonomous Vehicles: The Application Of Discrete Choice Modeling And Machine Learning, Sangwan Lee

Dissertations and Theses

New mobility technologies, such as shared mobility services (e.g., car-sharing) and, more importantly, autonomous vehicles (AVs), continue to evolve. The supply-side advancement will likely disrupt and transform transportation mode choice behaviors, and create a new paradigm since they are emerging and becoming increasingly feasible alternatives to the existing modes of transportation. Accordingly, this dissertation employs discrete choice modeling (DCM) and machine learning (ML) using a U.S. nationwide stated choice experiment to understand how travelers adopt new transportation modes or continue to use conventional modes of transportation.

This dissertation consists of three papers. The first examines future market shares of each …

Frequency Event Detection And Mitigation In Power Systems: A Systematic Literature Review, Umar Farooq, Robert B. Bass

Electrical and Computer Engineering Faculty Publications and Presentations

Modern power systems characterized by complex topologies require accurate situational awareness to maintain an adequate level of reliability. Since they are large and spread over wide geographical areas, it is inevitable that failures will occur. Various generation and transmission disturbances, such as generator and transmission line tripping and load disconnection, give rise to a mismatch between generation and demand, which manifest as frequency events. These events can take the form of negligible frequency deviations or more severe emergencies that can precipitate cascading outages, depending on the severity of the disturbance and efficacy of remedial action schema. The impacts of such …

Performance Of An Environmentally-Aligned, Low Maintenance Flood Alleviation Scheme On The Burn Of Mosset, Forres, Scotland, Matthew F. Johnson, Patrick Edwards, Rachael Todd, Janine M. Castro, Colin R. Thorne

Environmental Science and Management Faculty Publications and Presentations

Flooding of the town of Forres, Scotland prompted the implementation of a flood alleviation scheme (FAS) featuring a low earth-fill dam constructed upstream of the town to create a flood retention area, limiting peak discharges entering the urban area. Flow through the dam is controlled by a weir, and it was recognised that if coarse sediment, large wood, and/or debris collected at the weir this could adversely affect its performance. To ensure reliable operation of the weir, the “Burn Management Works” (BMW) were designed to reconnect the embanked, elevated river channel to its floodplain, naturally retaining coarse sediment, large wood, …

The Future Of Camera Technology With Atul Ingle, Atul Ingle

PDXPLORES Podcast

Single-photon camera sensors have the potential to revolutionize digital camera technology. These sensors can capture individual photons at high speeds, circumventing some of the limitations of current digital camera technologies. One challenge, however, is the sheer amount of data generated by the sensor, which is a hindrance to their widespread adoption. With the support of the National Science Foundation, Assistant Professor Atul Ingle is developing algorithms to solve this problem--algorithms that could enable the adoption of single-photon sensors in applications ranging from autonomous vehicles to medical imaging and the cameras in cellphones.

"We've Created Cheap Energy Off The Backs Of Salmon": Dam Removal Politics And Alliances In The Lower Snake River Basin, Krista Harrington

Dissertations and Theses

Dams, once considered by many to be good for water development in the Western U.S., might not be a part of a climate resilient future. Dams have come under increasing scrutiny due to undesirable ecological implications. Although dam removal proposals are growingly popular in recent decades, they are controversial since they impact different stakeholders in different ways. In the Pacific Northwest, the Lower four Snake River dams have long been criticized for their negative impacts on salmon. In February 2021, US Congressman Mike Simpson (R-Idaho) proposed a comprehensive framework to deconstruct the Lower four Snake River dams as an attempt …

Buildings are critical environments governing our collective exposure to air pollution and energy consumption. While there exist concerns regarding increases in building energy consumption due to indoor air interventions, improvements to the quality of air indoors can improve health, comfort, and productivity. Air cleaning technologies that can improve indoor air quality with minimal energy consumption have become ever more important. These technologies are utilized at various scales; from passive removal of pollutants in the air entering the indoor environment to active cleaning of air within the breathing zone. To better understand the effectiveness of active and passive ozone mitigation technologies …

Mapping Ecosystem Service Flows Of Estuary Restoration Projects On The Oregon Coast To Identify Impacted Stakeholders, Shersten King Finley

Dissertations and Theses

The recent impetus for estuarine restoration has largely focused on resolving key ecological problems; however, less is known about how people might benefit or be impacted by restoration. By mapping benefits that flow from functional salt marshes and estuarine systems I examined how different social groups might be impacted by restoration based on race and class. In this study, I considered three ecosystem services (recreation, aesthetics, cultural/historical/spiritual) and where they might impact surrounding communities. In this paper I argue that stakeholder groups can be identified by mapping ecosystem service flow areas. I hypothesized that these three ecosystem services would have …

A Three-Dimensional, Analytical Wind Turbine Wake Model: Flow Acceleration, Empirical Correlations, And Continuity, Zein Ahmad Sadek

Dissertations and Theses

A new, three-dimensional, analytical, steady state wake model is presented which includes local flow acceleration near the rotor improving wake description compared to existing models. Wake structures such as the momentum deficit and regions of accelerated flow are concisely described with compound and normal Gaussian functions. Large-eddy simulations (LES) are used as training data to develop the model using two, inline turbines under various inflow conditions parameterized by hub height wind speed and turbulence intensity. Mass conservation is considered by fixing two components of the wake velocity model and optimizing the third to best satisfy continuity; after which, the model …

An Examination Of Educator Perspectives On Career And College Pathways For Black, Indigenous, And Students Of Color With Disabilities, Rachel Anne Herrick

Dissertations and Theses

Black, Indigenous, and students of color (BIPOC students) in high school, who are dually experiencing the socially constructed labels of race and disability (BIPOC-SWD), are not provided with equitable access to Career and College Pathway (CCP) programs, which contributes to a lack of preparedness and success within postsecondary settings. Despite school reform policy efforts that incorporate Culturally Relevant Pedagogy (CRP) and Career and College Readiness frameworks, BIPOC-SWD perpetually have lower achievement rates, poorer postsecondary outcomes, and are less prepared for careers or college.

Utilizing a Disability Critical Race Theory (DisCrit) lens, this comparative case study was used to examine educator …

Accounting's Problematic Relationship To Legitimacy: A Review Of The Critical Literature, David Maddox

Hatfield Graduate Journal of Public Affairs

Accounting is the practice of measuring, documenting, and reporting on the economic dimensions of an organization, institution, or activity. Traditional views of accounting see it as a value-free technique to provide information for decision-making, and as such, compliance with standard accounting practices bestows legitimacy. In the 1970s and 1980s, critiques of the view of accounting as a neutral tool for rational decision-making emerged. These critical studies of accounting identified ways in which accounting was constitutive of reality rather than reflective, submerged conflicts and depoliticized internal relationships under a unitary image of the entity, provided tools of visibility that contributed to …

A New Approach To Machine Learning Hardware Classifier Design Based On Functional Decomposition Of Multi-Valued Functions, Saad Mohammad Al-Askaar

Dissertations and Theses

This dissertation presents a novel design of a hardware classifier based on combining modified Ashenhurst-Curtis Decomposition and multiplexer-based synthesis. The PSUD classifier brings three new contributions: an approach to solve the column multiplicity problem, an approach to encode multiple-valued variables, and a decomposition algorithm based on modified Ashenhurst-Curtis Decomposition. One of the biggest challenges in Boolean function decomposition is the variable partitioning problem. Thus, we introduce a new representation of two combined classifiers for multiple-valued functions to overcome the variable partitioning problem which allows finding the minimal column multiplicity and consequently to find high quality decompositions leading to a good …

Methodologies For Quantum Circuit And Algorithm Design At Low And High Levels, Edison Tsai
