229 - Power Dynamics in Close Peer Relationships: Associations with Adjustment
Get PDFVery little research has examined power in peer relationships, as they are assumed to be egalitarian (Blieszner & Adams, 1992). Although this is generally found to be true for college students (Furman & Buhrmester, 1992), this isn’t always the case. In romantic relationships, having equal power or more power has been associated with higher self-esteem (Galliher et al., 1999; Hall & Knox, 2019). This presentation highlights preliminary analyses from an ongoing project examining associations between perceived power and adjustment among college students in their same-sex friendships, other-sex friendships, and romantic relationships. We used cluster analysis to group the students into four profiles based on their reports of the power dynamic in these three relationships. Students who felt that they had more power in all three relationships had the best self-esteem and the lowest levels of internalizing problems and externalizing problems. In the other clusters, the power dynamic in their romantic relationship seemed to have the strongest association with their self-esteem and adjustment outcomes
028 - Chemistry of Colored Glass in Slag from Ironville, NY
Get PDFIn Ironville, New York, smelting for iron was performed from 1828 to 1886 and left behind piles of waste called slag. Ironville is located in the Adirondack Mountains, west of the High Peaks Wilderness. Slag is the leftover byproduct of smelting for a specific ore, and the slag in Ironville is predominantly glassy and sometimes vesicular. Ironville slag comes in a variety of blues, purples, white, and greens, and some are swirled with two or more distinct colors. Five slag samples were selected because of their singular color, and one was selected due to its pattern of dark and light blue bands. Small fragments of these samples were broken, embedded into epoxy, and polished to a smooth surface for study with the Scanning Electron Microscope (SEM). Chemical data for each sample was obtained using energy dispersive spectrometry (EDS). All samples, regardless of color, contained O, Si, Ca, Mg, Al, Fe, Na, and K (listed from high concentration to low). There were no significant differences in the chemistry of all the samples, suggesting that color differences are more due to trace elements rather than major elements. In the banded sample, small changes between Ca and Si content do seem to be at play
185 - Nonviolent Pedagogy: Reimagining Undergraduate Philosophy Education
Get PDFTraditional undergraduate philosophy education (UGPE) often prioritizes dominant historical viewpoints (DHVs) while marginalizing less commonly taught philosophies (LCTPs). This exclusion creates epistemic injustices, limiting student engagement, agency, and opportunities for meaningful contributions to philosophical discourse. My research explores how incorporating principled nonviolence into pedagogy can address these systemic limitations. Nonviolent Pedagogy (NVP) is an approach that fosters dialogical learning, student agency, and epistemic justice by modifying traditional curricular structures and instructional methods. This framework draws on the Kingian model for nonviolent social change, ungrading methodologies, and inclusive epistemological frameworks to create a more participatory learning environment. Through intentional leadership and classroom design, NVP encourages students to engage in philosophical inquiry beyond rote memorization, promoting critical engagement with diverse perspectives. This poster presents key arguments for integrating NVP into UGPE, outlining the philosophical justification for such modifications, practical applications for curriculum design, and the broader implications for the discipline of philosophy. By fostering learning agency and reducing systemic epistemic barriers, NVP not only enhances student experience but also advances philosophy as an evolving, inclusive dialogue
039 - Designing an Educational Lab: Using Dry Ice to Demonstrate Carbon Dioxide as a Greenhouse Gas
Get PDFThis project aimed to create a laboratory experiment for educational use to show that carbon dioxide in an atmosphere acts as a greenhouse gas. An experiment of this kind was first done in 1856 by Eunice Foote providing evidence that Carbon Dioxide could cause warming in the atmosphere. Initially, four tubes had increasing amounts of Dry Ice placed in them with a fifth tube left with no dry ice as a control. The hypothesis was that as the amount of dry ice in each tube increased, the temperature should increase faster based on there being higher concentrations of CO2 released in the tubes. A second attempt was made in which two had dark colored minerals were added to help with the absorption of energy from the sun. A third iteration of the experiment was attempted using two Tupperware containers with the bottoms blacked out, one of which had dry ice placed in warm water and the other was sealed with just the normal atmosphere, and both were placed under identical grow lights. The temperatures gathered in the three iterations were inconclusive on showing Carbon Dioxide is a greenhouse gas. Future attempts to reproduce the greenhouse gas effect should explore how to better seal the containers used to ensure none of the Carbon Dioxide concentration leaks out, making sure the conditions in each container have completely equal conditions, and exploring the effect of using a grow light versus actual sunlight
181 - Investigating the Role of Flexible Loop Mutations in Malate Dehydrogenase: Structural and Kinetic Impacts on Enzyme Catalysis
Get PDFMalate dehydrogenase (MDH) plays an essential role in metabolism by catalyzing the reversible conversion of malate to oxaloacetate in the tricarboxylic acid cycle. This reaction, which also generates NADH, is critical to metabolic homeostasis across species. Although the general structure and function of MDH are well-characterized, the contribution of its conserved “flexible loop” region to substrate binding and catalysis remains insufficiently understood. In this project, we investigated how point mutations within this loop affect enzymatic activity in Citrullus lanatus (watermelon) glycosomal MDH (wgMDH), a model system with a well-characterized expression protocol and sequence. We introduced four site-directed mutations—R130A, R130E, R124K, and R124A—into the wgMDH gene via Q5-based mutagenesis in sister laboratories. These constructs were transformed into E. coli TOP10 cells for plasmid propagation and later into BL21(DE3) cells for expression and purification. Wild-type and mutant proteins were expressed under IPTG induction and purified by Ni-NTA chromatography. Protein levels were determined using the Bradford assay, and purity was assessed by SDS-PAGE. We are now optimizing protein expression and purification methods, aiming to perform kinetic assays with varied concentrations of key MDH reactants; which will further elucidate how flexible loop mutations affect overall enzymatic activity. By analyzing the effects of these mutations on catalytic efficiency and substrate interaction, we aim to deepen our understanding of MDH’s structural dynamics. Our findings may inform the broader significance of loop-mediated regulation in enzymes and support future therapeutic exploration, particularly as MDH is indeed a potential target in parasitic diseases like African trypanosomiasis
031 - Measuring the Success of Remediation using Ostracodes in the Western Finger Lakes, NY
Get PDFConesus Lake, a mesoeutrophic lake located in the Finger Lakes, has experienced environmental disruptions over the past centuries. Conesus Lake contains six species of ostracods, Cypridopisis vidua, Candona candida, Candona ohioensis, Candona ellipitica, Darwinula stevensoni, and Limocythere verrucosa. These species reflect the lake\u27s environmental conditions, including remediation efforts used to restore it. This study aims to show the effectiveness of remediation using the diversity and abundance of ostracodes found in the lake. Cores were collected from the south basin of Conesus Lake. Samples of sediment were collected at one-centimeter intervals from 3 cm to 154 cm. Subfossils were separated from the sediments, sorted, and identified to the lowest level. 1,363 ostracodes were found from 51 horizons in the core. Cy. vidua and Ca. candida were the most prevalent. Cy. vidua had the most overall abundance throughout the core whereas Ca. candida showed elevated abundance at both the top and base of the core. Ca. ohioensis displayed lower abundances near both core-bottom and core-top with peak abundance mid-core whereas Ca. elliptica displayed moderate abundances near core base with infrequent occurrences near core-top. We propose Ca. candida and Cy. vidua may be indicators of mesotrophic conditions, Ca. ohioensis may indicate eutrophic conditions and Ca. elliptica may be indicative of more oligotrophic conditions. The return of Ca. candida and Cy. vidua near the core-top reveals the positive impact of remediation on the ecosystem and monitoring live ostracodes can be used to indicate the lake’s trophic state
