Regional Characteristics And Variability Of Extreme Precipitation And Atmospheric Rivers In Past, Present, And Future Climates Over The Contiguous United States, Emily Anne Slinskey

Dissertations and Theses

This dissertation examines the regional and seasonal variability of extreme precipitation and atmospheric rivers (ARs) across the contiguous United States (CONUS) in past, present, and future climates. An extreme precipitation categorization scheme, designed to monitor and track the multi-scale variability of extreme precipitation, is applied to a range of precipitation measurement products as an assessment of observational uncertainty. To investigate the importance of ARs across the CONUS, an objective AR identification algorithm is applied to global reanalysis to identify and characterize AR characteristics regionally over the observational record. Projected change in AR day frequency, geometry, intensity, and associated precipitation is …

Climate Model Evaluation Of Atmospheric Rivers Over The Contiguous United States, Ilan González-Hirshfeld

Dissertations and Theses

Atmospheric rivers (ARs)--long corridors of intense atmospheric water vapor transport--significantly influence the hydrologic cycle and regional hydrometeorological extremes across the contiguous United States (CONUS). Ongoing and future climate change may alter AR characteristics and impacts, making confident climate model projections of future change, especially at regional scales, of critical importance. In order to better constrain uncertainty in such projections of future change, we perform a comprehensive climate model evaluation of AR climatology over the CONUS. Using an established AR detection algorithm, we evaluate the representation of ARs in historical simulations (1984-2013) from a suite of models participating in the sixth …

Relationship Between Image Spectroscopy Spatial Resolution And Crown Level Tree Species Classification Accuracy, Andrew Richard Fritter

Dissertations and Theses

Hyperspectral imagery has become a common remote sensing data type used in tree species classifications because of its rich spectral signals that allow the detection of the variations in canopy reflectance. While high spatial resolution hyperspectral imagery provides fine spatial resolution for discerning surface objects, it has the inherent drawbacks of expensive acquisition costs, large data sizes, and can be computationally taxing to use. This study attempts to determine a relationship between crown level tree species classification accuracy and hyperspectral spatial resolution. Future tree species classification projects can make use of this relationship by targeting a spatial resolution that best …

Projections Of Large-Scale Atmospheric Circulation Patterns And Associated Temperature And Precipitation Over The Pacific Northwest Using Cmip6 Models, Graham Patrick Taylor

Dissertations and Theses

Projections of 500 hPa geopotential height (Z500) patterns over the Pacific Northwest of North America and their associated surface temperature, precipitation, and frequency of occurrence are assessed using models from the 6th phase of the Coupled Model Intercomparison Project (CMIP6). The self-organizing maps approach is applied to reanalysis data from the Modern-Era Retrospective Analysis for Research and Applications, version-2 (MERRA-2) to cluster daily Z500 anomalies into 12 representative patterns that span the range of historical circulation patterns. CMIP6 data for daily Z500 anomalies are mapped to each node for historical and end of century global warming experiments, and the resulting …

The Residential Property Value Premium Of The Proximity To Carsharing And Bikesharing Services: Evidence From New York City, Sangwan Lee, Aaron D. Golub

Urban Studies and Planning Faculty Publications and Presentations

While significant existing scholarship has confirmed that accessibility to “macro” transportation systems, such as transit, creates some value for real estate, few studies have examined the capitalized effect of “micro” transportation modes on property values. Even, despite the increased ridership and market shares of carsharing and bikesharing services, empirical evidence on its property value capitalization effects of the emerging transportation services remains far less limited. In this context, this research examines the residential value uplift induced from the proximity to carsharing (Zipcar) and bikesharing (CitiBike) services in New York City by employing Spatial Durbin Models with sales transaction data that …

Racialized Space: Historical, Economic, And Social Factors Contributing To The Gentrification Of North & Northeast Portland's Albina Neighborhoods, Red Burkett

University Honors Theses

Portland, Oregon has long held the reputation of being a quirky, artistic, mid-size American city for the ecologically friendly and progressively minded. What is less well-known is that Portland has a long history of segregation, racial violence, and public policy that is often viewed as hostile by the Black residents, especially the Albina neighborhoods of North and inner-Northeast Portland. Since Dr. Gibson published Bleeding Albina: A History of Community Disinvestment in 2007, terms such as gentrification, redlining and restrictive racial covenants have become more common in academic and social parlance concerning Portland. In this thesis, we will explore how gentrification …

Understanding The Taboo Of Incest In The American South Through Analysis Of Southern Gothic Literature, Grace Young

University Honors Theses

In this paper, I am exploring the topic of incest through the lens of the Southern Gothic literature genre. I am interested in why the American South has the stereotype of having more prevalence of individuals who engage in incest in mountain communities versus other parts of the communities in America. I explore the intersectionality of race, geographic isolation, religion, and the taboo of incest in a small community. I use the texts of William Faulkner, Cormac McCarthy, and Breece D'J Pancake to do in-depth analysis of Southern Gothic themes such as taboo, family secrets, Christianity, and the grotesque. By …

Racializing Discourses: An Exploration Of Moreno Subject Formation In Oaxaca, Mexico, Juan Salvador Sepulveda-Figuereo

Dissertations and Theses

Processes of Black racialization in Mestizo Latin America open a space to expose how subjectivities emerge and change while in tension with broader national ideas and transnational discourses. Morenos, typically dark skin individuals of African descent, inhabit the boundaries of mestizaje, Mexico's national racial ideology which emphasizes indigenous and Spanish ancestry. As a result, regional narratives subject morenos to racialization processes that align with the historical erasure of people of African descent, effectively excluding morenos from the nation. Nevertheless, morenos incorporate themselves into the regional and national narratives through various mechanisms and (re)formulations of established discourses.

I propose a …

Globalizing Noncitizen Detention, Jaye Balentine

Anthós

This inquiry seeks to establish that the global expansion in regimes of noncitizen detention represents a contemporary expression of imperial subjectification under Western liberalism and that such regimes serve a key role in maintaining the capitalist social order. While several efforts have been made to explain the globalization of noncitizen detention practices stemming from the United States, there exists serious shortcomings in the proposed analyses. Namely, existing literature on the subject has failed to adequately account for the history of Western imperialism and the centrality of liberalism as a political ideology in this imperial project. By intervening in the existing …

Do Secondary Cyclones Increase The Category Scale Of Atmospheric Rivers?, Edgar Sanchez Fausto

University Honors Theses

Atmospheric rivers (ARs) play a crucial role in delivering precipitation worldwide. This makes them an important phenomenon for water resource specialists to study. One such interest is to understand what mechanisms make ARs produce significant rainfall and associated hazards such as flooding. One possible mechanism is that AR duration or intensity may increase when it interacts with a secondary cyclone, either of which can increase the AR category scale. The purpose of this study is to determine whether AR and secondary cyclone interactions increase the category scale ARs. Out of 52 AR events analyzed, 32 events contained at least one …

The Impact Of Adverse Childhood Experience (Aces), Future Adult Incarceration, And Poor Mental Health- A Literature Review, Letasi M. Burgess

Our Peer The Pigeon: Impacts Of The Covid-19 "Anthropause" On Psu Campus Urban Foragers, Audrey Douglass

University Honors Theses

The 2020 COVID Pandemic presented a paradigm shift dubbed, by some scholars, the 'Anthropause', an ecological epoch in which humans faded from the public sphere. As was the case for many urban species that depend on the foraging of food waste, this meant a fundamental disruption to their food systems and to the entire urban eco-web. The PSU Campus Park Blocks presents a unique opportunity to observe animal behavior, while also a succinct microcosm to study food waste flow changes, and compare species layout to other urban parks in the METRO area. Decreased food waste output from proximal …

Noise As Music: Effects Of Physical And Digital Noise In One's Life, Juliana Bigelow

University Honors Theses

Sound is something to be thought about critically. It is not just a part of our world, but it helps define it. This thesis follows the development of five short sonic compositions created from field recordings of the researcher's environments between June 2020 and March 2021. Through techniques such as granular synthesis, soundwalking, and text scores, the compositions demonstrate how noise in both physical and digital sonic environments can impact one's identities, relationships, health, transitions, and ideas of music. Critically thinking about sound can lead us to a better understanding of ourselves and others and allows us to begin creating …

North American Expatriates In Mexico: A Discourse Analysis Of Facebook Groups, Liliana Carolina Brock

University Honors Theses

North American expatriates in Mexico often live in enclaves or affluent communities at a fraction of what it would cost in the US or Canada. Despite living in Mexico for years, many expatriates are poorly integrated into Mexican culture and society. This integration is made more difficult because many are unable to speak Spanish fluently. Instead, expatriates rely on English language Facebook groups to help them navigate life in Mexico. While scholars have explored the intersections of communication and interculturalism in expatriate communities, comparatively few have explored how the internet and the presentation of self on social media (specifically Facebook) …

Towards An Evolutionary-Institutional Analysis Of Landlordship, Jaye Balentine

University Honors Theses

This inquiry considers the social phenomena of landlordship and traces its evolutionary tendencies. Furthermore, this effort argues that since the 18^th century through the present, landlordship can be viewed as an institution that is caught in a Teufelskreis, a vicious cycle that is related to ever-increasing emphases upon pecuniary values, that comes with a related tendency for ever increasing impersonal relations between tenant and landlord. This inquiry relies upon an evolutionary approach, considering the institution of landlordship since the emergence of capitalist landlords in 18^th century England--that runs up through the present. Using an evolutionary-institutional approach drawing …

Colorism In Mexico: An Examination Of Inequality And The Psychological Impact In The Form Of Depression, Ana K. Kinzie

University Honors Theses

Mexican society is engaging in racism in the form of colorism; while colorism is widespread, it is not acknowledged by the population. As a previous Spanish colony, the effects of the social caste system affect how Mexicans view themselves and others, creating a preference for lighter skin tones. The idea of Mexicans being a hybrid race (Mestizo) prevails in the country, which affects racial minorities as they are often ignored. Skin tone in Mexico can affect the socioeconomic status of their population and the chances of social mobility. While research on how colorism affects the mental health of Mexicans is …

How Can Portland's Urban Landscape Better Utilize Stormwater?, Joni Frame

University Honors Theses

This thesis worked to explore stormwater management and water runoff using urban green infrastructure in Portland, Oregon. Water management systems are used to store and treat stormwater (precipitation) that runs off impervious surfaces in our built environment. Stormwater is produced by rain and other forms of precipitation that runs off impervious surfaces such as streets, parking lots, and other sites. Climate changes are projected to include more frequent and more intensive storms which can lead to extreme flood hazards, increasing the stormwater runoff. This study analyzed the context of climate change in the city of Portland, OR, to understand how …
