Decoding Bacterial Resilience: sRNAs and Sigma Factors in Stress Adaptation and Persistence of Salmonella
Full text linkSmall RNAs (sRNAs) are noncoding RNA molecules in bacteria that function primarily to regulate gene expression, including those associated with stress. The Borchert Lab has identified 173 sRNAs and \u3e 500 sRNAs that are responsive to desiccation and carbon starvation (c-starvation), respectively. Prokaryotic transcription involves an RNA Polymerase (RNAP) that transcribes DNA into RNA. RNAP involves sigma factors, which recognize promoters for the initial steps of RNA synthesis. The Borchert Lab has determined that there are significant overlaps between sRNAs expressed in cells subjected to both short-term durations and long-term durations of carbon starvation. Salmonella enterica serovars can have outbreaks associated with dehydrated foods. Understanding the mechanism that allows for S. enterica survival under stress allows for building strategies in combating the spread of this pathogen and preventing recurrent Salmonella outbreaks. We hypothesize that in S. enterica serovars, the bacteria express sigma factor RpoS during short term stress while switching over to sigma factor RpoE during long term stress. This switch between the sigma factors function to regulate the stress response in S. enterica. RNAP sigma subunit selection and the expression of distinct sRNAs drive the decision between active stress resistance and formation of persisters. Our findings suggest that sigma factor expression of RpoS in the Salmonella strain SL1344 is dependent on the duration of stress.https://jagworks.southalabama.edu/honors_college_posters/1042/thumbnail.jp
Perceptions of Power and Consent: The Role Gender, Race, and Sexual Orientation in Shaping Public Perceptions of Student-Teacher Affairs
Full text linkSexual violence is a taboo topic. It is especially challenging to acknowledge child victims. Sexual violence in schools is particularly hard to acknowledge. No parent wants to consider the possibility of sending their child to a predator every day. This phenoma has been researched for decades from various angles. This project will contribute to the research that looks at the ways race, gender, and sexual orientation influence perception of victimhood.https://jagworks.southalabama.edu/honors_college_posters/1036/thumbnail.jp

Episode 6 - Conclusion
No full textIn this sixth and concluding episode of the podcast, the students reflect on some of the things that they learned from the archived interviews, the interviews that they conducted, and from putting together this podcast series. Community member Yvonne Reed Matthews joins them and shares in the reflective process with the team. We hope you enjoyed this podcast.
What Happened Down the Bay? is a podcast created by University of South Alabama students in summer 2025, through the Jean O’Connor-Snyder Internship Program (JOIP) funded by the David Mathews Center for Public Life. Down the Bay is a historic Black neighborhood south of downtown Mobile, Alabama, and this podcast explores the history of Down the Bay as community members have related it through oral history interviews. In preparation for the internship, students participated in an oral history seminar with Drs. Ryan Morini and David Messenger, working with interviews from the Down the Bay Oral History Project collection at the McCall Library before meeting with elders from the community and recording new interviews for the collection. The podcast combines clips from the archived interviews with students’ reflections on how their own home communities and experiences relate to those that people describe from Down the Bay
Episode 4 - Businesses
No full textThis fourth episode in the series focuses on the businesses and other institutions described in the interviews for the Down the Bay Oral History Project. The student hosts reflect on the connections they see between these histories and their own lives and communities.

Reframing Rudeness: Exploring Positive Reappraisal as a Pathway from Customer Incivility to Self-Efficacy
No full textCustomer incivility is a persistent challenge for front-line employees (FLEs), often leading to adverse workplace outcomes. This research examined whether positive reappraisal can transform incivility into a source of growth. Grounded in Social Cognitive Theory, the research explored how positive reappraisal mediates the relationship between customer incivility and two key forms of self-efficacy—regulatory emotional and workplace social—ultimately influencing job satisfaction. The moderating roles of perceived organizational support and trait mindfulness were also investigated.
A cross-sectional survey of 296 FLEs was analyzed using partial least squares structural equation modeling (PLS-SEM). More specifically, the results confirmed customer incivility positively predicts positive reappraisal. Additionally, customer incivility indirectly enhances self-efficacy and job satisfaction via positive reappraisal. Mediation analysis further reveals positive reappraisal serves as a competitive mediator, counteracting the direct detrimental effects of incivility. Surprisingly, FLEs\u27 perceived organizational support weakened the positive reappraisal pathway, suggesting highly supported employees may rely less on individual coping strategies.
These findings challenge the prevailing view of customer incivility as a purely negative antecedent, uncovering its potential to foster resilience. Organizations could support employees by incorporating cognitive reframing techniques into training and balancing support systems to promote adaptive coping. This research offers a more nuanced perspective on workplace stressors and their potential to drive positive outcomes
