Investigating the role of PLN in Brain and Behavior
Ben Klocke
Intracellular Ca2+ homeostasis is critical for a wide range of cellular processes in neurons. As such, dysregulation of Ca2+ homeostasis has been implicated in many neuropsychiatric and neurodevelopmental disorders, including bipolar, schizophrenia, and autism. Given the importance of proper Ca2+ handling, neurons have evolved a diverse Ca2+-handling “toolkit” to tightly regulate the trafficking of Ca2+ throughout cellular and subcellular compartments such as endoplasmic reticulum (ER), which functions as a key intracellular Ca2+ storage unit. One critical ER Ca2+ regulatory protein is the sarco-endoplasmic reticulum Ca2+ ATP-ase (SERCA2), which pumps Ca2+ ions into the ER lumen and is vital to proper Ca2+ homeostasis in not only neurons, but in all mammalian cell types. Interestingly, studies from our lab have exposed phospholamban (PLN), a SERCA2 regulator previously thought to have a largely cardiac-specific function, to be expressed in the thalamic reticular nucleus (TRN) of the mouse brain. Using a constitutive global PLN knockout mouse model, we found that PLN plays an important role in regulating locomotor activity; we then developed and employed a novel TRN-specific conditional knockout mouse model to investigate the role of PLN in TRN-dependent behaviors such as sleep and executive functioning. Overall, these findings provide the first evidence that PLN plays a role in the brain and advances our knowledge on the role of TRN in the regulating of brain and behavior.

Investigating the Theory-Practice Gap in Sales Engineering Transitions
Jack Kenneth Doll
This research paper reports the investigation of the theory-practice gap that exists for engineering graduates transitioning into sales engineering or technical sales roles. Sales engineering is the practice of employing technical knowledge to facilitate the sales process of complex engineered products and services, acting as a bridge between engineers and customers. A balance of technical knowledge and sales acumen are critical to success in these positions . To investigate this theory-practice gap, the researcher employs a mixed-method design consisting of self-assessment surveys directed at current and previous sales engineers to gauge their readiness and skills at graduation versus the skills they have acquired throughout their career. These surveys explore the aspects of missing skills, if any, that they have observed in their industry experience. This research provides valuable insights for educators, industry professionals, and aspiring sales engineers, facilitating a more seamless integration of theory and practice in this growing field.

Is There an Inverse Relationship Between Utility Sector Stock Returns and Rising Interest Rates? An Empirical Analysis, 1999-2023.
Andrew Charles Kohnen, Cannon Spelman
Financial economists believe that utility sector stocks are bond proxies i.e., as yields on bonds increase, utility sector stock prices will decline. In this study, I test the hypothesis that an inverse relationship also exists between rising Federal Funds Rates and utility stock movements. For my test, I use four periods of rising Federal Funds Rates since 1999. These periods have different macro characteristics, with two occurring after an economics recession, one during a period of modest inflation and slow but steady economic growth, and the most recent period, February 2022 - August 2023, where inflation is high and rising and the Federal Reserve is aggressively raising the Federal Funds Rate. I use the Top 20 stocks by market in the utility sector to carry out my analysis.

Is urban farming the bee's knees? A socio-ecological study on the effect of pollinator recruitment methods on pollinator communities in urban agriculture.
Samantha B. Urquidez
Pollinators are essential to agriculture and with the increase in urban farming, there is great concern regarding insect pollinators in urban spaces. While there has been extensive literature looking at bee abundance and biodiversity in urban environments, there has been little research studying the efficacy of currently utilized pollinator recruitment practices in urban agricultural systems. In Dayton, Ohio, and the surrounding area 18 urban agricultural sites have been sampled for insect pollinator activity utilizing timed observations, pan traps, and hand netting. In addition to traditional methods of looking at pollinator activity, an important component of this research includes a sociological study that looks at the farmers themselves and how their efforts may be affecting the pollinator activity observed on their agricultural plots. To examine this relationship, we conducted an electronic survey and one-on-one interviews with each of the farmers in addition to our biological sampling. Our goal is to better understand the factors impacting pollinator activity and what pollinator recruitment methods are most effective in an urban environment.

Jesuits, Jews, and Jacobins: A polite disagreement between Don Luigi Sturzo and Hannah Arendt
Laura T. Coughlin
This paper, Jesuits, Jews, and Jacobins: A polite disagreement between Luigi Sturzo and Hannah Arendt, exposes original research funded by the University of Dayton and performed at the archives of the Istituto Luigi Sturzo in Rome. The essay is part of a larger dissertation project that endeavors to clarify the conservative and religiously inflected antifascism of Don Luigi Sturzo, Italian priest-politician and founder of the Partito Popolare Italiano (PPI). In August of 1942, Hannah Arendt and Don Luigi Sturzo, both wartime exiles in the United States, exchanged letters related to Arendt’s groundbreaking essay, “From the Dreyfus Affair to France Today.” This correspondence reveals a genuinely civil conversation between partners engaged in dialogue about the most significant European issues of the long nineteenth century and the effect of those issues on the twentieth century. Of particular interest is their debate in three areas on which Arendt drives the conversation: 1) the relationship of the Society of Jesus to the formation of negative Catholic attitudes about the Jews of Europe, 2) the importance of personal political formation to a democratic tradition that enforces individual and human rights, 3) the distinction between the “mob” and the “people.” As to this last point, the former (“mob”) is large, emotional, violent, and easily led to reaction (e.g. Fascism) especially in corrupt states. By contrast, the latter (“people”) is small, rational, consistent, and able to secure the integrity of the laws.

Kinematics of Inextensible Constant Curvature Model for the Design of Minimally Invasive Surgical Robots
Yucheng Li
Continuum robots are inspired by biological organisms such as snakes, octopus tentacles, and elephant trunks to replicate their flexibility. These robots can navigate complex and confined spaces, enabling them to adapt to changing shapes and surfaces and interact delicately with environments without causing damage. Hence, their inherent flexibility and maneuverability make continuum robots ideal for surgical procedures in minimally invasive surgery (MIS). However, MIS requires exacting precision in both the position of the surgical robot end-effector and the shape of the continuum robot backbone. Additionally, the high flexibility of continuum robots introduces complexity in motion planning and control. To address these challenges, this study focuses on two key aspects: understanding kinematic redundancy and locomotion in the inextensible continuum robot and proposing a novel design of the backbone and actuating system of the continuum robot to enhance backbone stiffness without loss of flexibility. The DIMLab's prior research has successfully achieved the objective of comprehensively understanding the kinematics of continuum robots, enabling their application in the medical field.

Chancelon Rice
Through working with and meeting with ULeaD I was able to learn networking, leadership, and social skills. Understanding how your background can affect how you lead.
Leadership to me looks like understanding yourself to best understand those around you. When you as a leader are your best self you can empower those around you to be the best version of themselves and produce their best work.
The legacy I hope to leave is someone that anyone could feel like they could go to. A resource for anybody at the University, to where even if I don’t have the information I can get them in touch with someone who will.
