    Bipartite Intrinsically Knotted Graphs with 21 Edges

    No full text
    A graph is intrinsically knotted if there exists a knotted cycle in every spatial embedding of the graph. Using the restoring methods, Kim, Mattman, and Oh construct a complete listing of intrinsically knotted bipartite graphs with 22 edges. In this study, we adapt their strategy to show the Heawood graph is the only intrinsically knotted bipartite graph with 21 edges

    Schenectady\u27s Voices: Stories from Four BIPOC Locals Changing Their Community

    No full text
    In this paper, I will reflect on my visual art thesis painting project, going more in depth about the process, my inspiration, and my subjects. For my project, I wanted to highlight individuals from the Schenectady area that have experienced adversities but have chosen to give back to the community despite them. As a result, I created 4 large scale portraits of people of color who live and work in Schenectady, New York. I met with and interviewed Sherain Rivera, Sookyung Lee, Will Rivas, and Jamaica Miles. The four of them serve and are very involved in their community in multiple ways. Talking with them gave me the opportunity to learn more about them and their stories of determination. The purpose of this project was to give them, and more broadly, the marginalized communities in the Capital Region more representation in a space where they have felt ignored and discriminated against. Throughout this paper, I explain my process of learning to paint with oil for the first time, the struggles I faced with making large scale portraits, and my inspiration for the project. I also discuss three professional artists that influenced my work along the way: Jordan Casteel, Amy Sherald, and Alice Neel. Lastly, I give a brief description of each of the personalities and stories of my models, and connect them to the larger purpose of my work, which is to invoke empathy within my viewers

    Improving Human-Robot Interaction: Modifications of a Social Robot on Dimensions of Gender and Personality

    Previous research in Human-Robot Interaction (HRI) has shown that social female robots typically evoke more cognitive and affective trust. Studies also show that extroverted robot personalities are associated with desirable social outcomes. In this experiment, I tested the extent to which a robot\u27s gender (male vs. female) and personality (introverted vs. extroverted) impact the success of a given human-robot interaction. Specifically, I evaluated if the gender of a robot has an effect on the human preference for extroverted personalities. Prior to interacting with a robot, participants completed a baseline Negative Attitudes Towards Robots Scale [9]. Then, during the interaction, the robot asked the participant a variety of questions in an interview-like manner. After this dialogue concluded, the robot requested the participant to execute a task, which was used as a behavioral measure. Once the participants were done with the task, they completed two self-report measures: a Robot Comfort Scale [9] and a Robot Reaction Scale [7]. Results showed that participants felt more comfortable interacting with the extroverted female robot compared to the introverted female robot. However, the opposite was true for the male robot: participants felt more comfortable interacting with the introverted male robot compared to the extroverted male robot. Furthermore, participants tended to have better general reactions to the extroverted female robot compared to the introverted male robot. This study demonstrates that the notion of extroverted robots yielding desirable social outcomes is not generalizable on dimensions of gender

    The Effect of Religiosity, Partisanship, and Identity-Seeking Behavior on Political Engagement

    Is politics increasingly substituting for religion as a source of identity? As organized religion is on the decline in the United States and the nones (those who are Atheist, Agnostic, or claim no religion) continue to be some of the most politically active people in the country, it seems that there is a shift away from religion and towards politics. The present study explored this idea by testing the relationships among religiosity, identity-seeking behavior, and political engagement. I hypothesized that people seeking an identity would become more politically engaged after a partisan threat, especially if they were lower in religiosity. I recruited 197 participants from the survey platform Prolific, who completed a series of scales relating to religiosity, partisanship, and identity-seeking. Participants also were randomly assigned to read a paragraph that either threatened the partisan identity of Democrats or Republicans, followed by questions about their future political engagement intentions. Linear regression analyses (though not statistically significant) revealed a trend in the data consistent with predictions: People low in religiosity, yet high in identity seeking, were more likely to say they wanted to engage politically in the future compared to people low in identity seeking. These findings have implications for the future navigation of our political and religious landscape as organized religion continues to decline and partisanship continues to become heightened

    The Development and Testing of a Clean Cookstove Testbed

    There are many people in developing nations who do not have access to modern cooking facilities (i.e., sinks, stoves, microwaves). In these nations, people often must cook over traditional cookstoves, which are essentially just open fires with stones added to support a pot or cooking vessel. The field of improved cookstoves has developed, which looks to design improved alternatives to traditional cookstoves. The goal of this project was to enable Union to participate in experimental ICS research, by developing a testbed in which ICS can be tested, and then determining the capabilities and limitations of the testbed itself. In doing this, we hope to learn about and hypothesize areas in which Union may be able to further develop improved cookstoves. After initial tests confirmed that the testbed could contain - and safely remove from the lab - all cookstove exhaust, we began running small fire tests in a commercially available rocket stove (a common type of ICS). These tests provided information on both the rate and total amount of fuel use. Temperature readings were also recorded at different locations on the testbed to ensure it did not become too hot during extended testing (i.e., did not exceed maximum temperature ratings for the materials). It was further observed (qualitatively) how much smoke was being released from the stove. Additionally, the flow was measured in the lab\u27s exhaust ducts using a flow grid and micromanometer. Through these tests and continuing tests in the future, it will be determined, with better certainty, what the capabilities and limitations of our cookstove testbed at Union College are, and therefore, how we will be able to research, test, and improve on ICS technology

    Effect of interest rates on firms\u27 performance in developing European countries

    No full text
    The central bank uses monetary policy to maintain the balance of the economy in the country. Each country in Europe has a central body that regulates the total supply of money and supports economic expansion. By using expansionary and contractionary monetary policies the central bank in each country targets inflation and keeps unemployment low. The central bank frequently employs the discount rate, open market operations, and reserve requirements as its three primary monetary policy tools. Through monetary policy, the central bank affects the profits, revenue, income, investment, turnover, and long-term and short-term liabilities of businesses. Adjusting interest rates influences the borrowing and expectations of firms. In order to grow, firms need to focus on labor, technology, marketing, investing, capital, and customers. This research focuses on the effect that interest rates have on businesses\u27 performance in European countries, particularly in nations that are members of the European Union but are not in the Eurozone such as Bulgaria, the Czech Republic, Hungary, Poland, Romania, and Sweden as well as East European nations that are neither members of the EU nor the Eurozone such as Albania, Azerbaijan, Belarus, Bosnia and Herzegovina, Georgia, Kazakhstan, Moldova, Montenegro, North Macedonia, Serbia, and Ukraine. Using 1995-2019 data from the statistical websites of each country and the World Bank, this study finds that interest rates have a negative effect on firms\u27 performance in these European countries

    Association Between Previous Mental Health Disorders and Post- COVID-19 Conditions

    The COVID-19 pandemic has proven to be challenging to many scientists and physicians due to its rapid spread and long lasting effects. The objective of this study is to determine whether high levels of psychological distress leads to increased risk of developing post-COVID-19 conditions (long COVID). A total of 55 participants from a small family practice in New York State were the sample for this study. Patient charts were reviewed to gather PHQ-9 scores and look for diagnoses of long COVID symptoms. The results did not reveal any significant relationship between mental health conditions and long COVID symptomatology

    The Dream Thief

    No full text
    In a world where humans are granted with the ability to live lucidly in their dreams, seventeen year old Saturn is incapable. Saturn believed she was unable to dream at all, that was until a scientist, Dr. Robino, revealed she is capable of much more: entering the dreams of others. When she begins to invade the dreams of her architect neighbor Fawn, she starts to question Dr. Robino\u27s morals
