“Circumstances of such atrocity:” Violence and Federal Authority in the Lower Ohio Valley Borderlands at the Turn of the Nineteenth Century
The following thesis examines the murder of three Lenape (Indigenous people commonly called Delaware) in 1797 in what is now southern Indiana. Two men and one woman were killed by three Euro-American settlers residing in central Kentucky. The murder became an issue in the negotiations of treaties with various Indigenous Nations in the early years of the Indiana Territory in 1800. The analysis includes the economic and geographical factors that brought the murderers and those murdered together. There is particular focus on the gendered economic roles of Indigenous women in the Ohio Valley and the role of lower-class Euro-American settlers in Kentucky. The paper also examines the layered sovereignties and shifting imperial boundaries during the period that complicated the attempt to prosecute the murderers. Federal officials trying to bring justice or advance imperial agendas did not enjoy the authority necessary to do either smoothly. Illustrated in the thesis is the transition, in Ohio Valley, from a physically violent “frontier” settler economy, which understood physically plundering Indigenous wealth as a legitimate endeavor. The transition from a powerful Indigenous economy, justice, and politics to a system of exploitation dominated by the government and predatory traders created conditions for revolution among Lenape and other Indigenous communities in Indiana.
The narrative approach to the analysis relies on the close reading of primary source material mostly generated by federal officials and court documents as they attempt to capture and try the three Euro-American murderers. To construct a rich context of geography, environment, politics, and economy the thesis draws on recent scholarship in both Indigenous and borderlands history
CHEMOTAXIS OF PANTOEA SP. YR343 IN A SYNTHETIC POPULUS DELTOIDES RHIZOSPHERE
The colonization of plant roots by bacteria found in rhizosphere can help plants adapt to stresses. Colonization is facilitated by a rhizobacteria’s ability to recognize and move towards a plant root, frequently using chemotaxis. This study examines the chemotactic response of the rhizobacteria Pantoea sp. YR343 towards metabolites known to be produced by the roots of poplar trees: glucose, sucrose, salicin, myoinositol, citric acid, succinic acid, malic acid, glycerol, and amino acids (serine). Identifying which compounds Pantoea sp. YR343 is chemotactic towards is important to understanding the establishment of the plant-microbe interface. Chemotaxis was characterized by methods such as soft motility assays, capillary assays, 2D videos, and Digital Holographic Microscopy. The chemotactic activity of a transposon mutant of the methyl-accepting chemotaxis protein (MCP) PMI39_02190 was also compared to the wildtype strain. From these experiments, it was found that the wildtype strain is chemotactic towards malic acid and myoinositol while PMI39_02190 may be chemotactic towards malic acid. These results continue to inform how the bacteria recognize and establish a relationship with plants, using Pantoea sp. YR343 and Populus deltoides as models
Attachment and detachment kinetics of FtsZ filaments
An important step in the initialization of bacterial cell division is the formation of the Z-ring. The Z-ring consists of FtsZ (proto)filaments anchored to the cell membrane via linker proteins. FtsZ filaments begin to form in the cytosol and eventually condense near the middle of the cell to form the Z-ring; however, the steps involved are not completely understood and are difficult to observe in experiments. We attempt o break down the process of Z-ring formation in Escherichia coli into a series of simpler processes and use molecular dynamics to gain insight into the details involved. We have developed two different simulations, one to study the attachment of the filament after its collision with the inner membrane and the other to implement the slower reaction-diffusion process that occurs due to many filament attachment and detachment events. We use the LAMMPS package for the former, and for the latter, we use our original C++ code. In the LAMMPS simulations carried out on the Summit supercomputer at ORNL, the FtsZ filaments are modeled as rigid, ball and chain polymers decorated with linkers. Using these linkers, filaments can attach to the cell wall due to an effective potential which combines the effect of interaction between different linker proteins, the filament, and the cell. From this model, we extract the attachment rates of filaments colliding with the membrane at different angles, and compare them to a theoretical model. We also use a modified coarse grain model to estimate the bending energy of a rigid filament and investigate the detachment process. Finally, we present results from further work that integrate these results into a full reaction-diffusion model, where the process of attachment is modeled as a reaction which is rate-limited by the diffusion of the filament to the membrane
“NATURE NEVER FORMED SUCH AN ADVANTAGEOUS PLACE:” MOUNTAIN LOGISTICS AND WARFARE IN THE TRANS-APPALACHIAN SOUTH, 1756-1776
This thesis will examine two significant periods of conflict in between the Cherokee and Euro-American military forces in the trans-Appalachian South. The first period is a series of three punitive campaigns launched by the British against the Cherokee from 1759 to 1761. The second period concerns near-simultaneous punitive campaigns launched by the newly independent colonies of Georgia, South Carolina, North Carolina, and Virginia against the Cherokee in 1776. It examines several aspects of these conflicts. First, the impact of the mountain environment, an unrestrained culture of war, and the objectives on the nature of the battles. Second, it analyzes the adaptation of logistics to the trans-Appalachian environment. Lastly, it examines the tactical adaptations of the Cherokee, British, and South Carolinians in three battles

AI Chatbots and Subject Cataloging: A Performance Test
Libraries show an increasing interest in incorporating AI tools into their workflows, particularly easily accessible and free to use chatbots. However, empirical evidence on the effectiveness of these tools to perform traditionally time-consuming subject cataloging tasks is limited. In this study, researchers sought to assess the performance of AI tools in performing basic subject heading and classification number assignment. Using a well-established instructional cataloging text as a basis, researchers developed and administered a test designed to evaluate the effectiveness of three chatbots (ChatGPT, Gemini, Copilot) in assigning DDC, LCC, and LCSH terms and numbers. The quantity and quality of errors in chatbot responses were analyzed. Overall performance of these tools was poor, particularly for assigning classification numbers. Frequent sources of error included assigning overly broad numbers or numbers for incorrect topics. Though subject heading assignment was also poor, ChatGPT showed more promise here, backing up previous observations that chatbots may hold more immediate potential for this task. While AI chatbots do not show promise in reducing time and effort associated with subject cataloging at this time, this may change in the future. For now, findings from this study offer caveats for catalogers already working with these tools and underscore the continuing importance of human expertise and oversight in cataloging
Site Supervisor Roles and Responsibilities: Counseling Programs’ Written Expectations
Site supervisors play a vital role in training clinical mental health counseling (CMHC) students during their field work. While clear roles and responsibilities for site supervision is a professional and ethical requirement, the scope of these expectations remains ambiguous. This article provides baseline empirical data on the expectations of sites and site supervisors communicated through field experience handbooks of CACREP-accredited CMHC programs. The authors completed a qualitative content analysis that resulted in three key categories including Site and Site Supervisor Administrative Expectations, Clinical Supervision, and Site/Program Interaction. Implications for counseling programs and future research are discussed
Forging Ahead in Florida: Teaching and Supervision Strategies in the Face of Legislative Restrictions and Medical Bans
As a nation and a profession, we have witnessed a spark in the momentum and uplifting of social justice movements and advocacy concerning the ongoing oppression of Black, Indigenous, and People of Color (BIPOC) as well as sex and gender-expansive (SGE) people in our community. In response, Florida and other states face an onslaught of restrictive medical bans and legislative bills surrounding how counselors and educators address race, sexuality, and gender in treatment and training programs. Florida has notably been at the forefront of adopting this legislation, not only regulating instructor-led discussion around racism, same-sex relationships, and gender identity in various educational settings but also banning gender-affirming medical care for transgender youth. In this article, we review the legislative and regulatory impacts of race, sex, and gender-based legislation in Florida on education and healthcare, providing strategies for counselor educators, counselors, and trainees in the areas of teaching and supervision
