The focus of this research was to examine and establish a baseline study that may assist in future monitoring and documentation of this historic limestone structure on stone weathering. A replicable methodology was specifically created toward this baseline research in hopes that it represented a solid baseline study. Observations and data analyses revealed the relationship between the architectural limestone building structure and the dominating recession …

Tree-Ring Reconstruction Of Ouachita River Streamflow, Keaton Cade Jenkins-Joyce

Graduate Theses and Dissertations

The Ouachita River drains the Ouachita Mountains and Upper Coastal Plain in Arkansas and Louisiana. The Ouachita River is used for navigation, power generation, recreation, water supply, and wastewater treatment. The river has been prone to low flows during drought and extreme flooding, which were principal justifications for the construction of three large multipurpose dams on the stream. It is likely that the use of the Ouachita River will be stressed by future population growth, economic expansion, and climate change. For this study, tree-ring chronologies from various locations in and near the Ouachita River drainage basin were used to reconstruct …

Development Of A Historic Digital Elevation Model (Hdem) From Archival Aerial Imagery Over The Black Mountain Alluvial Fan, Canada, Emma Menio

Graduate Theses and Dissertations

In a rapidly changing Arctic, reconstructing landscapes pre-warming is essential to understanding impacts due to climate-inducted geomorphic change. High-latitude elevation datasets extend temporally back to the 2000s, while region-wide warming became measurable in the 1980s. Historic aerial imagery archives provide datasets of high-resolution imagery from the mid- to late- 1900s with stereo-capability that can be harnessed to create historic digital elevation models, or hDEMs. A major issue with reconstructing a surface from the past is finding a way to constrain it in space, given a lack of ground control from that era, especially at high latitudes. The main purpose of …

The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins

Graduate Theses and Dissertations

It is generally appreciated that there is a relationship between the relative size of the incisors, mandible length, and diet in primates. More specifically, the differences in relative incisor size among primate species are believed to be evolutionary adaptations to their use during food processing and acquisition. While this satisfactorily explains relatively large incisors, it fails to address the relatively small incisor size seen in many taxa. One hypothesis is that there is a trade-off between molar size and incisor size in species with relatively short mandibles. The following study uses two-way ANOVA to evaluate the possibility that spatial constraint …

Fair Canonical Correlation Analysis, Zhuoping Zhou, Davoud Ataee Tarzanagh, Bojian Hou, Boning Tong, Jia Xu, Yanbo Feng, Qi Long, Li Shen

Faculty, Staff and Student Publications

This paper investigates fairness and bias in Canonical Correlation Analysis (CCA), a widely used statistical technique for examining the relationship between two sets of variables. We present a framework that alleviates unfairness by minimizing the correlation disparity error associated with protected attributes. Our approach enables CCA to learn global projection matrices from all data points while ensuring that these matrices yield comparable correlation levels to group-specific projection matrices. Experimental evaluation on both synthetic and real-world datasets demonstrates the efficacy of our method in reducing correlation disparity error without compromising CCA accuracy.

Apples And Oranges, Daragh Henchy

Postgraduate

This exegesis delves into the complex relationship between cinema and art, focusing on the development of story documents within the cinematic arts. Positioned within the realm of practice-led research, it is an academic companion to a creative work—a fantasy murder mystery augmented treatment set in Paris, 1914. The exegesis and the creative work collectively aim to describe an aesthetic experience akin to that of fine art, drawing upon Gilles Deleuze’s taxonomy of cinema, specifically the concepts of movement-image and time-image.

. Central to this study is the exploration of how cinema, as a form of art, engages with philosophical ideas …

Performing Motorized-To-Non-Motorized Crash Analysis Using Multi-Model Lbs Traffic Data Calibrated Through Random Forest Models, Nicholas Aldridge

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Traditionally, traffic prediction has been an engineering challenge due to insufficient quantities of data. In this thesis, the use of a new type of data called location-based service (LBS) data from StreetLight (StL) and a large database of multi-modal traffic counts are used to infer vehicle, pedestrian, and bicycle volumes on all road segments in Lincoln, Nebraska. Additional land use features are incorporated into the model from the EPA Smart Location Database (EPA-SLD). The use of random forest models provides strong measures of fit for all modes, with R² scores of 0.98 for both the bicycle and pedestrian modes …

The Landscape Of Community-Based Giving Days In The United States, Abhishek Bhati, Andrew Burk

The Foundation Review

Within the last decade there has been an exponential growth of community foundation- led giving days, credited in general to the ease afforded by online giving, the social media presence of nonprofits, and the sense of community these events widely impart. However, current academic literature on these events remains sparse. This article addresses this gap with a longitudinal examination of the growth of community foundation-led giving days from 2009 to 2022.

The study found only two giving days led by community foundations in 2009, peaking at 78 in 2020, and plateauing to 71 giving days in 2022. In 2020, the …

Reconciling Philanthropy’S Role In Disruption And Revolution: Hard Lessons From A Community-Driven Power-Building Strategy To Achieve Health Equity, Kien S. Lee, Courtney Ricci, Mia Ramirez

The Foundation Review

This article shares The Colorado Trust’s experience with Community Partnerships for Health Equity (CPHE) after initiating a resident-led strategy for systems change and encountering the myriad challenges to its implementation that ultimately led to exiting the initiative.

The CPHE strategy intended to fund community members directly instead of working through the nonprofit sector in the state, and thereby shift power from nonprofit organizations to residents. It eventually involved more than 20 communities across Colorado and created change in certain communities — from filling service gaps and creating local partnerships to shifting local systems.

The Trust had good intentions in its …

Protecting Brazilian Amazon Indigenous Territories Reduces Atmospheric Particulates And Avoids Associated Health Impacts And Costs, Paula R. Priest, Florencia Sangermano, Allison Bailey, Victoria Bugni, María Del Carmen Villalobos-Segura, Nataly Pimiento-Quiroga, Peter Daszak, Carlos Zambrana-Torrelio

Geography

Indigenous territories are considered important for conservation, but little is known about their role in maintaining human health. Here we quantified the potential human health and economic benefits of protecting these territories in the Brazilian Amazon, by using cardiovascular and respiratory diseases cases, pollutant and forest cover data. Between 2010 and 2019, 1.68 tons of Particulate Matter of small size (PM_2.5) were released every year, with negative effects for human health. A lower number of infections was also found in municipalities with more forested areas, and with a low level of fragmentation, which probably is related to the …

Examining Current Bias And Future Projection Consistency Of Globally Downscaled Climate Projections Commonly Used In Climate Impact Studies, Lucas Berio Fortini, Lauren R. Kaiser, Abby Frazier, Thomas W. Giambelluca

Geography

The associated uncertainties of future climate projections are one of the biggest obstacles to overcome in studies exploring the potential regional impacts of future climate shifts. In remote and climatically complex regions, the limited number of available downscaled projections may not provide an accurate representation of the underlying uncertainty in future climate or the possible range of potential scenarios. Consequently, global downscaled projections are now some of the most widely used climate datasets in the world. However, they are rarely examined for representativeness of local climate or the plausibility of their projected changes. Here we explore the utility of two …

Social Media Impacts On Arkansas Consumer Perceptions Of Gmos, Elizabeth R. Berner

Graduate Theses and Dissertations

This study builds upon previous consumer perceptions of GMOs studies. A need existed to determine what, if any, effects social media messages about GMOs had on consumer perceptions in Arkansas. The study utilized a qualitative approach with three focus groups. Data were analyzed using descriptive code. Participants were found to have a general understanding of GMOs, though discussion about what a GMO product was took an uncertain tone. Most participants did not consider GMOs as a factor when purchasing products. Rather participants considered characteristics such as price, quality, and convenience. Participants did not believe the infographics had changed their opinions …

Assessment Of Needs And Priorities For Precision Agriculture And Soil Testing In Arkansas, Solomon Frimpong

Graduate Theses and Dissertations

Optimum crop production is needed to meet the growing population's food, water, fiber, and energy needs. However, agricultural productivity is hampered by many destabilizing factors such as pest management challenges, declining water quantity, and climate change which threaten long-term food security. Maximizing productivity will require optimizing resources through Precision Agriculture (PA) by supplying inputs based on crop needs. Precision Agriculture offers tools that can be used to optimize crop management practices globally. However, stakeholders’ perceptions and the lack of data-driven site-specific recommendations limit stakeholders’ ability to fully harness the potential benefits of PA. Identification of stakeholder needs and approaches to …

Exposure To Climate Change Information Predicts Public Support For Solar Geoengineering In Singapore And The United States, Sonny Rosenthal, Peter J. Irvine, Christopher L. Cummings, Shirley S. Ho

Research Collection College of Integrative Studies

Solar geoengineering is a controversial climate policy measure that could lower global temperature by increasing the amount of light reflected by the Earth. As scientists and policymakers increasingly consider this idea, an understanding of the level and drivers of public support for its research and potential deployment will be key. This study focuses on the role of climate change information in public support for research and deployment of stratospheric aerosol injection (SAI) in Singapore (n = 503) and the United States (n = 505). Findings were consistent with the idea that exposure to information underlies support for research and deployment. …

Rapid Switching From Levetiracetam To Brivaracetam In Pharmaco-Resistant Epilepsy In People With And Without Intellectual Disabilities: A Naturalistic Case Control Study, L. V. Watkins, H. Dunstall, C. Musicha, C. Lawthom, K. John, C. Bright, C. Richings, K. Harding, S. Moon, S. E. Pape, R. Winterhalder, V. Allgar, R. H. Thomas, B. Mclean, R. Laugharne, Rohit Shankar

Peninsula Medical School

BackgroundApproximately one quarter of people with an intellectual disability (PwID) have epilepsy of whom nearly three-quarters are pharmaco-resistant. There are higher reported neuropsychiatric side-effects to anti-seizure medication (ASM) in this group. Levetiracetam (LEV) is a first-line ASM with a stronger association with neuropsychiatric symptoms for PwID than other ASMs. Brivaracetam (BRV) is a newer ASM. Recent studies suggest a beneficial effect of swapping people who experience neuropsychiatric events with LEV to BRV. However, there is limited evidence of this for PwID. This evaluation analyses real world outcomes of LEV to BRV swap for PwID compared to those without ID.MethodsWe performed …
