Near-Surface Thermodynamic Influences On Evaporation Duct Shape, Sarah E. Wessinger, Daniel P. Greenway, Tracy Haack, Erin E. Hackett

Marine Science

This study utilizes in situ measurements and numerical weather prediction forecasts curated during the Coupled Air–Sea Processes Electromagnetic Ducting Research (CASPER) east field campaign to assess how thermodynamic properties in the marine atmospheric surface layer influence evaporation duct shape independent of duct height. More specifically, we investigate evaporation duct shape through a duct shape parameter, a parameter known to affect the propagation of X-band radar signals and is directly related to the curvature of the duct. Relationships between this duct shape parameter and air sea temperature difference (ASTD) reveal that during unstable periods (ASTD < 0), the duct shape parameter is generally larger than in near-neutral or stable atmospheric conditions, indicating tighter curvature of the M-profile. Furthermore, for any specific duct height, a strong linear relationship between the near-surface-specific humidity gradient and the duct shape parameter is found, suggesting that it is primarily driven by near-surface humidity gradients. The results demonstrate that an a priori estimate of duct shape, for a given duct height, is possible if the near-surface humidity gradient is known.

From Parkland To Nashville: An Analysis Of Knowledge And Framing Activities In Reddit Discussions Surrounding News Coverage Of Guns In The United States, Corinne Dalelio, Dahlia Boyles, Kyle J. Holody, Wendy Weinhold

Communication, Media, and Culture

This research explores discussions surrounding news stories on r/news after two separate school shooting events in 2018 and 2023 to understand how and when variables related to knowledge exchange and framing emerge in context. These activities were found to be an antecedent to engagement, and exchanges of disagreement resulted in longer chains of discussion. ‘Metaframing’ was found to be linked to media distrust. Users in 2023 were far more ideologically aligned and shared knowledge more frequently, but cited sources less frequently, than in 2018. Implications for impacts of news, disagreement, and content moderation on online civic discourse are offered.

Relative Influence Of Sea State And Mean, Turbulent, And Heterogenous Refractivity On X-Band Propagation, Douglas M. Pastore, Erin E. Hackett

Marine Science

In predicting electromagnetic wave propagation within the marine atmospheric surface layer, it is common to assume steady homogenous conditions. However, discrepancies between predicted and measured propagation remain, which could be due in-part to turbulent fluctuations of the refractive index, spatially heterogenous evaporative ducting environments, and mischaracterization of the rough ocean bottom boundary. To better understand the relative importance of these contributors, this study explores the sensitivity of X-band propagation to parameters describing sea-state conditions and refractive environments, including turbulent fluctuations and spatially heterogenous conditions. This study employs the extended Fourier Amplitude Sensitivity Test to compute sensitivity indices that evaluate the …

Effects Of Urbanization On Eutrophication Parameters In Three Tidal Creeks, Ella Swantek

Honors Theses

Marshes and swashes are vital environments as a controlling barrier between land affected by various pollutants and the ocean. Eutrophication and the effects of this process can be detrimental for the areas experiencing it. I am interested in ways areas that have little contact with human interactions compare to areas that are heavily urbanized, and whether either of these locations is at a higher risk for eutrophication. Using spectrophotometry and fluorometry, I analyzed samples collected from the relatively undeveloped and restricted-access locations of Waities Island Beach and Dunn Sound monthly for dissolved nutrients, and chlorophyll. At the time of sampling, …

Sedimentary Conditions At A Tidal Creek That Exhibits Seasonal Pelagic-Benthic Variations, Jack B. Corbin

Honors Theses

Tidal creeks in the Grand Strand of South Carolina are small but numerous connectors between land and ocean. One of these creeks, White Point Swash, exhibits a seasonal switch between planktonic and benthic photosynthesizers. As plankton become less abundant in fall, benthic macroalgae bloom, aided by lower water levels due to fall-winter dredging of the main channel, until late Spring. This study builds on previous findings and examines sedimentary conditions at this site further. Sedimentary chlorophyll a (in microphytobenthos) and pore water nutrient concentrations are confirmed to be higher than water-column concentrations. Sedimentary nutrient fluxes to the sediment-water interface, calculated …

Use Of Space By Urban Loggerhead Shrikes (Lanius Ludovicianus) As A Window Into Habitat Suitability, Katie A. Maddox, Christopher E. Hill

Biology

Wild animals in urban environments face new challenges that may change how they use space and, at the same time, how they use space provides clues to suitability of habitat: bird territories in desirable areas tend to be smaller and populations denser. Loggerhead Shrikes (Lanius ludovicianus), historically associated with shortgrass habitats such as pasture and shrub steppe, occur widely in urban areas of the southeastern United States. For a complete picture of shrike use of space in urban spaces, we present three measures for a population inhabiting urban areas of Horry County, South Carolina: population density, home range size, and …

Effect Of Downregulating Lactate Dehydrogenase In Alzheimer’S Disease Using A Drosophila Model, Hannah Higgins

Honors Theses

According to the CDC, approximately 5.8 million Americans suffered from Alzheimer’s disease (AD) in 2020. AD is characterized by progressive memory loss and typically develops after the age of 60. There are many studies that suggest different causes of Alzheimer’s such as oxidative damage, amyloid plaque buildup, and metabolic dysfunction. Lactate Dehydrogenase (LDH) is an enzyme that is found in many tissues within the body and functions within cellular metabolism. The enzyme catalyzes the reversible reaction that converts lactate to pyruvate coupled with the reduction of NAD+ to NADH. Pyruvate is then used in the Krebs cycle to create ATP. …

Firm-Level Political Risk And The Cash Flow Sensitivity Of Cash, Hui Liang James, Hongxia Wang, Nilakshi Borah

Finance and Economics

We examine the impact of firm-level political risk on the cash flow sensitivity of cash. Using a large sample of U.S. firms from 2003 to 2018, we find that the cash flow sensitivity of cash decreases in political uncertainty and the impact of political risk is asymmetric to cash flow types (positive versus negative). Intensified political uncertainty induces positive/negative cash flow firms to reduce savings out of cash flows to finance investment opportunities/terminate unprofitable projects to retrieve cash. The results are robust to various model specifications, alternative variable definitions, and the control for non-political risks. In addition, we show that …

Between Religion And Politics: The Case Of The Islamic Movement In Israel, Suheir Abu Oksa Daoud

Political Science

The power of the “moderate” branch of the Islamic Movement (Alharaka al-Islamiyya, subsequently referred to as IM) Southern Faction (IMSF) in Israel stems from its ability to adapt to different situations, reconcile with the complex reality of being an indigenous minority in a state that defines itself a “Jewish state”, and operate within the state structure accepting democratic processes that have long been debated to clash with Islamism. Besides being represented in the Israeli Knesset since 1996, the culmination of this adaptation was the joining of the movement to the short-lived Zionist coalition government on 2 June 2021 (the government …
