Justice Bork, or, be careful which supreme court nominees you choose to fight
This study uses counterfactual analysis to assess whether a hypothetical Supreme Court with Robert Bork as a member would have decided cases differently than the actual Supreme Court.
I utilize both a qualitative analysis, and a quantitative Bayesian counterfactual model to predict Supreme Court case outcomes from 1988 to 2012.
The results show that several salient cases would have been decided differently, most of the decisions decided over the time frame would have remained unchanged. I also find that a hypothetical Supreme Court with Robert Bork as an associate justice would not have radically shifted rightward. Rather, the results show a brief rightward shift from 1991 to 1994, and a much longer and stronger rightward shift occurring after 2001.
The results suggest that scholars and pundits need to think more carefully about which Supreme Court nominees are should be contested in the advice and consent process – at least on political or ideological grounds.

Examining the Antecedents of Return Policy Leniency in eCommerce
As eCommerce has become widespread, the challenge of successfully navigating the returns process has grown perilous. The product returns issue is even more difficult for microenterprises that sell unique or custom products with fewer resources. The authors examined the impact of the antecedents of return policy leniency, specifically economic and social success factors. Using a web crawler over a 24-week period, the authors collected and analyzed data for a sample of 781 shops from Etsy, an eCommerce platform. Results indicate that the well-studied factor of sales, in addition to a new social factor – community dialogue – impacts an Etsy shop\u27s return policy leniency.

From fury to forgiveness: Exploring the mediating role of emotions in the relationship between crisis type, corporate social responsibility fit, and organizational outcomes
This study investigates how three types of emotions (anger, affective empathy, and cognitive empathy) mediate the relationship between crisis type and corporate social responsibility (CSR) fit and organizational outcomes such as purchase intentions, negative word-of-mouth (nwom), organizational reputation, as well as forgiveness. An online 2 (crisis type: product-harm vs. moral-harm) x 2 (CSR fit: high fit vs. low fit) between-subjects design (N = 412) was conducted with the participants recruited via CloudResearch, a crowdsourcing platform. The findings indicate that anger significantly mediates the relationship between crisis type and crisis outcomes, with product-harm crises increasing anger and leading to more negative outcomes. Conversely, high CSR fit reduces anger and enhances positive organizational outcomes. Affective empathy also mediates these relationships, with product-harm crises lowering affective empathy and CSR fit improving it, subsequently influencing purchase intentions, reputation, forgiveness, and negative word-of-mouth. Cognitive empathy partially mediates these effects, particularly affecting negative word-of-mouth, reputation, and forgiveness. These results suggest that managing stakeholder emotions through CSR alignment can effectively mitigate negative impacts during crises. Both theoretical and practical implications are discussed.

Loss of Courtship Suppression Memory in a Drosophila melanogaster Model of Alzheimer’s Disease
Alzheimer’s disease (AD) is the most prevalent and lethal neurodegenerative disease. Memory loss and motor dysfunction are accompanied by pathological hallmarks like neurofibrillary tangles or amyloid plaques. In this study, courtship suppression assay was used to assess learning and memory of a transgenic Drosophila melanogaster (the fruit fly) line expressing human Amyloid beta 42 (Aβ42). At young age (4–6 days old), both parental control and AD flies displayed lower courtship indices during training after being rejected by previously mated females. However, in the subsequent testing phase, young AD flies showed compromised recall memory, unlike that of parental controls. Neither control nor AD flies at 16–18 days old showed significant learning or recall memory. AD flies also exhibited age-related motor defects and presented amyloid plaques in brain sections. Interestingly, older AD flies displayed persistent chasing throughout the one-hour training period, and they attempted copulation at higher frequency than the untrained AD controls. Thus, transgenic AD flies displayed early onset of memory deficit, and aggressive courtship behavior as they aged.

Student-Parent Needs: A Study at Coastal Carolina University
This article focuses on Student-Parents as an under-represented group on Coastal Carolina University’s (CCU) campus. Student-Parents face many additional difficulties in their college experience, compared to traditional students. The goal of this study is to bring attention to the needs of student-parents on CCU’s campus and determine how certain stress factors related to being a student-parent can influence their college experience. We found that a majority of student-parents on CCU’s campus faced high levels of financial stress, academic stress, and social stress. As a result, we suggest providing additional resources for student-parents to use on CCU’s campus to help combat high levels of financial stress, academic stress, and social stress
Impacts of Hurricane Idalia’s Surge on Coastal Sand Biogeochemistry
Beaches are heavily influenced by extreme events, such as hurricanes. Biological and chemical processes, such as primary production and diagenesis are often interrupted by these events. To examine the effects of hurricanes on coastal biogeochemistry, this study used sand and porewater samples from Waties Island, SC, which were collected before and after Hurricane Idalia. The samples were analyzed for macronutrient concentrations, organic content, and chlorophyll concentrations. Macronutrient pore water concentration changes were not uniform. The inventory of nitrite decreased significantly after the storm, which was reflected in slight increases in the inventories of nitrate and ammonium. Concentrations of nitrate, which dominated the Dissolved Inorganic Nitrogen (DIN) pool, were more uniformly distributed throughout the sediment column after the surge, possibly indicating pore water mixing. Phosphate pore water concentrations and inventories only increased slightly post-storm but are not statistically different. The sedimentary chlorophyll inventory increased by 10% post-surge, probably indicating filtration of chlorophyll-bearing particles by the sediment column. Finally, organic matter content of the sandy column was higher post-surge, however it remained fairly low at less than 1%. These findings provide preliminary insights into the biogeochemical effects of a storm surge on a barrier island beach sandy column that are sorely lacking
HAB Cyanobacteria in Northeastern SC Retention Ponds: Time trends in abundance and relationship to water quality
The accumulation of polluted runoff in retention ponds can create water quality conditions that favor development of harmful algal blooms, including toxin-producing cyanobacteria. This can present a health risk to pedestrians and nearby residents, as many such ponds are surrounded by walkways or housing complexes. Blooms can also cause harm to natural ecosystems, periodically causing hypoxic conditions and toxin buildups. This study aims to form a more complete understanding of the population dynamics of certain potentially harmful phytoplankton genera, in relation to water quality parameters in retention ponds. Sampling was performed in five ponds chosen to reflect a variety of adjacent land uses. Eleven sets of samples were collected every other week for a period of six months. Cell abundance was quantified for five common and potentially harmful phytoplankton genera, which were chosen due to their prevalence in harmful algal blooms and potential for toxin production. Time trends in genera diversity and abundance were compared to water quality data to investigate relationships. A bloom event was captured at one location, and additional samples and data were collected over the course of the bloom to generate a more comprehensive data set
Relative Influence of Sea State and Mean, Turbulent, and Heterogenous Refractivity on X-Band Propagation
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 leading-order effects and effects due to non-linear interactions between these refractive and sea state parameters on a parabolic wave equation electromagnetic wave propagation simulation. The parameters are delineated and evaluated in three atmospheric stability regime experiments: stable, neutral, and unstable, and consider both trapping and non-trapping propagation conditions. Parameter sensitivity indices are ranked for each experiment to examine the relative effects of the parameters on X-band propagation prediction. The results show that in neutral and stable regimes, mean evaporation duct characteristics have the greatest impact on propagation beyond the geometric horizon, while in unstable conditions, turbulence also plays a significant role. Additionally, in the lowest 10 m of the atmosphere, forward scattering from the rough sea-surface has the greatest effect on propagation predictions regardless of atmospheric stability.
