Motherhood and Ethics with Sarah LaChance Adams
Get PDFOverview & Shownotes
We’re discussing motherhood with philosopher and director of the Florida Blue Center for Ethics Sarah LaChance Adams. She argues that we romanticize mothers, and in so doing ignore the pain and failure that come with caregiving. In her work, she explores the ambivalence of motherhood and what it can teach us about ethics. We discuss the ethics of parenting, Simone de Beauvoir, and much more on this episode of Examining Ethics.

Daughters of Sexual Politics: The Fujiwara\u27s rise to regency through romantic poetry and marriage
Get PDFThrough focusing on the patriarchal authority of Heian society, this essay seeks to establish a framework for the Fujiwara reconstructing the Heian political system. The primary idea will be to explain how the Fujiwara utilized poetry and marriage practices to conduct themselves to be integrated into the imperial family. The first section will provide background contextualization regarding aristocratic society, its cultural aesthetic focus, the functionality of the Heian ranking system, and the foundational court government, and explain how all of these aspects relate to the poetry and marriage systems. From there, the discussion will be focused on explaining the structure of romantic relationships in Heian aristocratic society. First, there will be a focus on the importance of poetry during the Heian period, both in its ability to provide a written form of communication and its functionality inside the Heian romantic process. Then the focus will look at the physical relations of marriage practices between the Fujiwara and the imperial family, looking to see how the marriage practices were in favor of the Fujiwara using their daughters as political tools to gain control over the Heian court. By manipulating the social and cultural elements of the Heian poetic and marriage systems of the mid-9th to 11th centuries, the Northern House of the Fujiwara clan was able to successfully take over both the political structure of the court system, alongside reaching the highest placements in the Heian society ranking system
Life on the Quarry Wall Vs the Quarry Floor: Parthenocissus quinquefolia
Get PDFParthenocissus quinquefolia, Virginia creeper, is found in two parts of the DePauw Nature Park quarry: vertically along the quarry wall and on large rock piles on the quarry floor. I looked into how these different habitats influenced the growth form, stress responses, and fitness of the P. quinquefolia growing in them. P. quinquefolia on the wall has higher chlorophyll a content and higher water content. There was also a higher percentage of flowering individuals on the quarry wall than on the floor. Lastly, the two habitats had vastly different morphological growth forms, with those on the wall having very long internodes compared to those on the floor. The data shows that P. quinquefolia on the quarry floor was more water and light stressed and had lower fitness; this suggests the quarry wall is a more suitable habitat for P. quinquefolia than the floor.https://scholarship.depauw.edu/srfposters/1128/thumbnail.jp
Gene Editing in Zebrafish for Modeling Nicotine Dependence
No full textThree genes for nicotinic acetylcholine receptors, the alpha 3 (chrna3), the alpha 5 (chrna5) and the beta 4 (chrnb4) gene have been linked to heavy smoking and smoking onset in humans. Mutations of these genes could increase the risk for developing lifelong nicotine dependence. To explore these potential risk factors we use zebrafish and apply molecular tools including CRISPR/Cas9 for generating gene-knockout mutations and CRISPR/BE4max for generating gene-editing mutations. These tools will allow us to determine if the chrna3, chrna5 and chrnb4 gene mutations are associated with changed nicotine sensitivity, nicotine seeking or nicotine avoidance behavior in zebrafish. Overall, one specific goal of the project is to develop zebrafish lines (or strains) without functional chrna3, chrna5 and chrnb4 genes (gene-knockout mutants). We successfully identified potential gene-knockout founder fish (F0) generated with the CRISPR/Cas9 method for the chrna3, chrna5 and chrnb4 genes. In addition, we were able to generate the first homozygous and heterozygous chrna3 gene knockout mutants and the first heterozygous chrna5 gene knockout mutants that we obtained through the Zebrafish Sanger Mutation project. In summary, we made significant progress towards establishing stable zebrafish homozygous and heterozygous gene knockout mutant lines for three nicotinic acetylcholine receptor genes that will be used for behavioral testing of zebrafish nicotine-seeking and avoidance behavior.https://scholarship.depauw.edu/srfposters/1124/thumbnail.jp

Avoidance behavior ecotoxicity testing of Oppia nitens in conventional microplastic and bioplastic spiked soils.
Get PDFEnvironment and Climate Change Canada recently completed a standardized protocol of ecotoxicity testing for Oppia nitens, a soil oribatid mite that performs crucial functions to support ecosystem services. Consequently, O. nitens is now recommended among the class of soil invertebrates for ecotoxicity testing, however, its applicability is limited by the paucity of data on its avoidance behavior to contaminants in soils. In this study, we examined the avoidance behavior of O. nitens to three different conventional microplastics (polyvinyl chloride/PVC, polyethylene/PE, polystyrene/PS) and two bioplastics (poly vinyl alcohol/PVA and sodium polyacrylate/NaPa) at five different concentrations following standardized guidelines. PVC and PE concentrations ranged from 857-9000 mg/kg. PS concentrations ranged from 92.59-972 mg/kg. For PVA and NaPa, concentrations ranged from 1543-16200 mg/kg. The O. nitens were exposed to the concentrations for 48 hours using a two-chamber test, to permit the choice between clean artificial and contaminated soil. Our results showed that O. nitens had an attraction to PVC at the two lowest concentrations, but no significant difference in response to the other concentrations. PE indicated an attraction to the lowest three concentrations, but an avoidance to the highest two concentrations (5000 and 9000 mg/kg). PS showed an approximate 75% avoidance at 300 mg/kg, but did not show avoidance at the other higher concentrations, which indicated immobilization or death. PVA indicated avoidance at the two highest concentrations (9000 and 162000 mg/kg) but no significant difference in response at the other concentrations. NaPa showed significant attraction at 9000 mg/kg, but significant avoidance at 162000 mg/kg. Attraction to low levels of contaminants has been termed hormesis, which can be seen especially if they are minutely required for normal metabolism. However, the hormesis-like pattern observed for the PVC, PE, and PS in this study could not be explained since microplastics are not a requirement for metabolic activities in mites compared to copper and zinc, where other studies have shown attraction to low concentrations of these metals. These results indicate that PS was the most toxic contaminant (LC50 = 172.7 mg/kg), and that bioplastics were not as lethal in comparison to the conventional microplastics (PVA LC50 = 8050.012 mg/kg and NaPa LC50 =14553.74 mg/kg). Therefore, bioplastics could potentially be a better alternative to conventional microplastics. The O. nitens is a promising species for avoidance testing in soil ecotoxicology and of great ecological relevance for assessing soils contaminated with pollutants. Since this is the first study investigating O. nitens avoidance to microplastic spiked soils, more studies are needed to evaluate its net responses to varying chemical classes in laboratory tests and applicability in contaminated ecosystems.https://scholarship.depauw.edu/srfposters/1113/thumbnail.jp
