Does exposure to positive climate action by others enhance efficacy and motivation to act?

Polling reveals that Northeast Ohio (NEO) residents are concerned about and desire action on climate change: 73% of NEO residents believe climate change is happening; 67% believe it is already affecting local weather; 65% think citizens should do more to address climate change. However, people across the Ohio routinely underestimate the concern of others by 21% and support for policies that address climate change by 29%. This is a problem because when individuals don’t think that other people care as much as they do, they are less likely to take action themselves. Does information about the concern and positive actions of fellow community members mobilize individuals to take action? “Community Voices” (CV), is a form of social media designed for display on digital signage and websites. CV combines images and quotes drawn from interviews to create and reinforce social norms. Prior research indicates that exposure to CV enhances concern and commitment to environmental action. We are designing a study to assess whether CV content can help close the gap between perceived and actual public support for climate action. In 2023 we conducted extensive interviews with a diversity of NEO residents who are engaged in a variety of positive climate action. Based on prior research2, we are designing an online experiment to assess whether exposure to CV content developed from these interviews increases motivation for climate action. Specifically, we hypothesize that exposure will: decrease psychological distance from climate change, increase the perception of climate action as a norm, and increase efficacy

Effects of Class Background on Marriage Attitudes in Oberlin Students

The rise of feminism transformed the economic function of marriage in America. As upper-class women joined higher education and the workforce, marriages with two incomes doubled the financial advantage of partnerships for wealthier people. Meanwhile, as debt and cost of living rose for poorer Americans, and the burden of child/elder care became harder to outsource, financial deterrents to marriage mounted in lower socio-economic strata. Subsequently, practices around marriage have diverged on class lines. Everything from age at first marriage, divorce rates, unmarried cohabitation, etc, are dramatically and increasingly different for wealthier vs poorer people. Questions follow. Has the social concept of marriage diverged along class lines? How likely are people to marry within their class? What are the motivators and deterrents to marriage for people of different class backgrounds? I conducted a mixed methods study, based on these questions. Data from the 2010 General Sociological Survey was analyzed to assess rates of cross-class relationships. Additionally, I conducted two in depth interviews with Oberlin students concerning their class backgrounds and general attitudes towards marriage. Results indicate that individuals are highly likely to marry within their class, even in supposedly class-homogenizing mate selection arenas such as college campuses. Qualitative data suggests this is in part due to a desire for a partner with similar class-informed values. Emotional labor vs ease, and financial incentives vs deterrents were cited as two such values. Additionally similar spending habits, lifestyles, and class-informed communication patterns, are perceived to increase likelihood of cohesion, and decrease conflict

Mail Myself to You: A Cinematic Journey Through the Oberlin College Mail Art Collection

Oberlin College’s Clarence Ward Art Library is the home of the Harley Francis Terra Candella and Reid Wood State of Being mail art archives, a vast collection of art which had been mailed from artist to artist through the postal service. The mail art movement began in the early 1960’s, emerging out of the Fluxus art movement and Ray Johnson’s New York Correspondence School. Mail artists have since desired to forge an artistic community outside of museum and gallery systems, an “eternal network” built on the principles of art being free and collaborative. The over 20,000 works of mail art in the Oberlin College Mail Art Collection– spanning a period of 45 years and 70 countries– have been handled entirely by student workers since their original donation and purchase. Every year, new students are trained on the library’s cataloging practices and history of mail art, able to interact intimately with every postcard, artist stamp, and envelope in the collection. The spring of 2024 marks Reid Wood’s final donation of mail art to the Clarence Ward Art Library, an apt moment to reflect on the history of mail art in Oberlin and beyond. This animated documentary film will explore the legacy and future of this extensive archive, posing questions regarding the ways humans communicate through art and the practices of preserving the memory of art that resists convention

Development of Activity-Based Protein Profiling Assays for the Human Rhomboid Proteases

Rhomboid intramembrane proteases (RIPs) are a family of serine hydrolases distinguished by their membrane-embedded active sites and proposed involvement in metabolic, and neurodegenerative diseases as well as cancer. Despite the ubiquity of these enzymes in all kingdoms of life, our knowledge of the enzymatic functions of RIPs is still quite limited. Consequently, the development of suitable substrate-based activity assays for these proteases has proved challenging due to the lack of known substrates. Activity-based protein profiling (ABPP) represents an alternative approach for studying the activity of these enzymes; in these assays, a small-molecule probe is used to engage the active enzyme by binding covalently to its active site. Here, we present our progress on the development of ABPP assays for the human RIPs. We expressed all five human RIPs (hRHBDL1, hRHBDL2, hRHBDL3, hRHBDL4, and hPARL), along with their inactive mutants, in HEK293T cells. We then screened a library of small molecule probes, including fluorophosphonates, b-lactams, and benzoxazinones, for their ability to engage the active enzymes, but not their inactive mutants, in a complex proteome. Probe labeling was visualized by performing the azide-alkyne Huisgen cycloaddition reaction with a functionalized rhodamine on probe-treated proteome followed by gel electrophoresis (SDS- PAGE). Through these efforts, we have identified activity-based probes for several of the human RIPs and observed differences in probe engagement in lysate versus intact cells. Our findings provide encouraging precedent for the development of suitable ABPP assays for each of the human RIPs as well as insight into the types of chemical scaffolds that could be used to generate inhibitors for these enzymes

Power and Emotion Perception from Faces and Bodies

The Face-Body Congruency Effect (FBCE) refers to the phenomenon whereby individuals are less accurate when categorizing emotional expressions from faces or bodies when the expression is paired with an incongruent emotional cue. Civile and Obhi (2016) discovered that priming individuals to feel powerful decreased the steepness of the FBCE for those individuals. The current research sought to simultaneously replicate these findings and investigate the mechanisms driving the effect. In this study, participants were randomly assigned to a power-priming condition or a control group and then asked to complete two emotion-recognition tasks in a randomized order. One task asked participants to quickly identify emotion from facial expressions while ignoring sometimes incongruent body language, and the other task asked participants to quickly identify emotion from bodies while ignoring sometimes incongruent facial expressions. Results indicated an overall effect of the FBCE, however in the face-recognition task, individuals were surprisingly more accurate at identifying faces when body language was incongruent. Individuals were also more accurate in the face task than the body task overall. No impact of power priming was identified in any analyses. Potential explanations for these results including the sample’s unusual relationship with power, issues with stimulus materials or faulty methods are discussed along with directions for future research
