Negation Patterns in the Conversational French of Tours, France: A Next-Generation Update
No full textLinguists have long observed variation in the use of the negative particle ne in French. Although this preverbal negative is required by standard French conventions regarding bipartite negation, ne occurs at low frequency in the negations of everyday spoken French. This study presents and analyzes a new corpus of sociolinguistic interviews recorded by the researcher in the city of Tours, France in 2024. The young adult speakers in the corpus were found to have an average ne-realization rate of 5.41%, which is significantly lower than the ne-realization rates reported by previous Tours negation studies in 1976 and 1996 but not significantly different from the results of a 2005 Tours study. Multiple linguistic and sociostylistic factors, including seriousness, emphasis, subject type, and phonetic environment, were found to influence the likelihood of ne-realization in negations.LinguisticsBachelors of Science (BS
Evaluating Recruitment of American Eel, Anguilla rostrata, in the Potomac River (Spring 2025)
Full text linkAmerican Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. Landings from Chesapeake Bay typically represent about 65% of the annual United States commercial harvest (ASMFC 2023). American Eel is also important to the recreational fishery as this species is often used as live bait for Striped Bass (Morone saxatilis) and Cobia (Rachycentron canadum). In 2021, Chesapeake Bay commercial landings of American Eel (284,297 lbs) represented 87% of the U.S. landings of yellow eel (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division). Since the 1980s, harvest along the U.S. Atlantic Coast has declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). The American Eel Benchmark Stock Assessment report (ASMFC 2012) established that the American Eel is depleted in U.S. waters. The most recent American Eel Benchmark Stock Assessment confirmed the stock remains depleted and abundance is lower than what was reported in the 2017 stock assessment update (ASMFC 2017; ASMFC 2023).Natural Resource
Self-leadership and teacher well-being: An internal family systems approach
Full text linkTeacher well-being is essential for student success, yet burnout remains a persistent challenge, especially after the COVID-19 pandemic. This study explores the use of the Internal Family Systems model as an innovative approach in supporting teacher well-being through the development of Self-Leadership. Conducted across seven schools in two school districts in the United States, this phenomenological study examines K-12 teachers’ experiences after participating in P.A.U.S.E., a well-being program designed to nurture their Self-Leadership. Through qualitative analysis of focus group data, we identified three key themes: 1) the transformative impact of Self-Leadership practices on teachers and students; 2) the importance of Self-Led facilitation and collaborative practice; and 3) a longing for more collective, systemic approaches to well-being across school communities. Findings suggest that integrating IFS concepts into well-being programs can enhance teachers’ ability to regulate their emotions, reduce stress, and improve teacher and student relationships. This study contributes to current understandings of teacher well-being by investigating how concepts from IFS, particularly Self-Leadership, can be effectively adapted to support both teachers and students in K-12 educational settings
Teachers’ Perceptions Of A School District’s Sheltered Instruction Observation Protocol Teacher Training Initative
No full textThe purpose of this study was to examine the implementation of the Sheltered Instruction Observation Protocol (SIOP) Model training initiative in classrooms. The theoretical frameworks were professional development (PD) and teacher self-efficacy. I sought to answer the following questions: To what degree are the eight components of SIOP being transferred into district teachers’ instructional practices, as perceived by teachers? To what degree do teachers perceive a sense of self-efficacy in implementing the eight components of SIOP? What conditions support and what conditions limit successful implementation of SIOP as perceived by teachers? What other recommendations and suggestions do the teachers believe would support the implementation of a successful PD on SIOP? This sequential mixed methods program evaluation study incorporated both quantitative and qualitative approaches, including surveys and interviews to answer the questions. The findings showed that teachers implemented lesson preparation and building background the most and interaction the least. Teachers asked for more training in certain components for greater self-efficacy. They experienced both support for and barriers to implementation in terms of teacher collaboration and administrative support. They also noted systemic barriers to implementation. Teachers wanted more training in specific SIOP components with consistent follow-up. As a result, three recommendations were generated. This began with identifying structural barriers hindering implementation of SIOP and alleviating them. Another recommendation was to conduct a small-scale education intervention to test the efficacy of SIOP and whether it shows positive outcomes in EL student success. Ongoing, sustained PD with follow-up by an EL specialist was also recommended.EducationDoctor of Education (Ed.D.
A Blueprint to Greener Shorelines: Advancing the Effectiveness, Sustainability, and Widespread Adoption of Coastal Nature-Based Solutions Through Transdisciplinary Research
Full text linkCoastal nature-based solutions (NbS) have emerged as powerful tools to enhance sustainable development and ecological restoration goals. As a rapidly growing field spanning across social, political, ecological, economic, and engineering disciplines, it is critical that researchers working in coastal NbS regularly attempt to identify emerging focal areas for scientific inquiry. Following the 27th Biennial meeting of the Coastal and Estuarine Research Federation, we provide a transdisciplinary perspective (including biologists, engineers, oceanographers, geoscientists, economists, and facilitators of workforce training programs) of pertinent research questions that, if answered, will advance the effectiveness, sustainability, and widespread adoption of coastal NbS. These suggestions for future research highlight the necessity for diverse expertise and perspectives at every stage in planning, design, implementation, and monitoring coastal NbS
Ancient women as actors in the legal systems of Arabia Petraea: Evidence from the Babatha Archive
No full textMy thesis investigates the experiences of women as actors in the ancient legal systems of the second century CE, focusing on multi-legal systems in Arabia Petraea that emerged to integrate Jewish legal traditions with Roman laws. I present a case study of the Babatha Archive—a collection of 35 legal documents belonging to a twice-widowed Jewish woman living in Arabia Petraea near the Dead Sea—to argue that Jewish women experienced reduced legal status as a result of the imposition of Roman law. Specifically, I conduct a textual analysis of the contracts, deeds, and personal correspondence contained in the Babatha Archive to examine legal practices associated with guardianship, marriage, and inheritance. I conclude from Babatha’s experiences that women suffered diminished legal status under multi-legal systems, particularly Jewish women whose access, agency, rights, and privileges were more protected under pre-existing Jewish laws and customs than under imperial Roman law.Classical StudiesBachelors of Arts (BA
Multicellularity in the 1,011 Saccharomyces cerevisiae Genome Panel
No full textThe transition from single-celled to multicellular organisms is one of the most important evolutionary transitions in life history. Most microbes are facultatively multicellular– they can live in a single-celled or multicellular form. By studying multicellularity in microbes, we can gain critical insights into how life on earth made the leap from one cell to many. The budding yeast Saccharomyces cerevisiae is capable of forming different kinds of multicellular structures under stressful conditions. Some of these multicellular phenotypes are associated with pathogenicity, and the ability to express the traits varies among strains. This study aims to leverage the power and diversity of the S. cerevisiae 1000 genomes panel to understand the distribution of and the correlation between multicellular phenotypes in a global yeast collection and to identify genetic variation underlying the traits. First, we conducted high-throughput phenotyping assays to screen for five types of multicellular growth: 1) pseudohyphal growth (PSH), 2) invasive growth (IG), 3) plastic adherence (PA), 4) biofilm formation (i.e., complex colony morphology, CCM), and 5) floating mats (flor). Next, we quantified all phenotypes, except for flor, using tailored computational image analysis pipelines. Our results showed that over ⅓ S. cerevisiae strains in the genome panel showed CCM, ⅖ strains displayed pseudohyphae, ⅕ strains grew invasively, ⅕ strain adhered to plastic, and over ⅕ strains formed flor. Employing phylogenetically-corrected correlational analyses, we observed associations between PSH and IG, and flor and PA. Finally, using our phenotyping results, we performed genome wide association studies (GWAS) on normalized values of the traits with corrections for population structure. Analysis of all traits uncovered 4286 significant SNPs, translating to 1960 genes underlying multicellularity expression, supporting a complex basis to, and abundant genetic variation for, multicellularity. A list of 8 genes involved in multicellular traits was narrowed down by focusing on genes that impact multiple phenotypes, contain multiple significant SNPs, and likely represent important targets that contain natural genetic variants. Using our GWAS results to build a protein-protein interaction network, we observed that a couple of genes in this list, MLP2, ELP2, MYO1, and IRA2, interact with over 40 other proteins in the network, further supporting their functional importance in forming multicellularity. Using our GWAS results, Gene Ontology (GO) analysis was conducted to cluster genes enriched in the process of forming multicellularity. Our results show that metabolic, biosynthesis of secondary metabolites, cell cycle, MAPK signaling, and Meiosis pathways are most significantly enriched. Ongoing work includes functionally validating the 8 genes identified through GWAS in the wet lab. Our results show there exists broad phenotypic variation and abundant genetic variation in multicellular traits across the 1000 genomes panel. Understanding the distribution, correlation, and the genetic basis of multicellularity can help us understand the environmental and genetic factors driving the evolutionary transition from single cell to multicellular organisms.BiologyBachelors of Science (BS

No full textThe Civil War disrupted the deep-rooted patriarchal culture of the South, and thus disrupted the traditional roles held by Southern women. By taking on supportive roles as nurses, laundresses, cooks, and spies, women were no longer confined to the domestic sphere. For Black women especially, the Civil War provided new opportunities to continue ongoing battles for freedom. The relocation of women to camp created tension between old codes of female civility and the new demands of the Civil War, ultimately resulting in the emergence of a new, adapted code of civility for Southern women. Unfortunately, the influence Civil War camps had in shaping Southern female identity is grossly underdeveloped. By examining the setting of war camps and the disparity of civil conventions across race and gender, this research will contribute to literary scholarship by illuminating how the Civil War altered Southern female identity for white and Black women, respectively.EnglishBachelors of Arts (BA
Measuring Neural Resonance Profiles Induced by Binaural Beats and their Relationship with Personality and Autism Spectrum Disorder
No full textPrior research has identified that binaural beats are associated with improvements in cognitive functioning (e.g., Kraus & Porubanová, 2015) and that binaural beats enhance oscillation in the brain (e.g., Fields, 2022). However, extant research has focused almost exclusively on a single canonical frequency band (e.g., theta, alpha) or isolated frequencies (e.g., 40 Hz) at a time, so little is known about patterns of neural resonance across the frequency spectrum and how these resonance profiles may be associated with differences in cognitive processes and personality variables. Furthermore, no study has systematically mapped resonance profiles across the oscillatory spectrum. Thus, the present study aimed to determine whether neural resonance profiles could reliably be measured using binaural beats to induce neural entrainment. We thus examined whether binaural beats would induce an increase in oscillatory power above that observed while listening to a pure tone at specific frequencies. We further aimed to address how any measured neural resonance profiles may correlate with relatively stable dimensions of personality. Participants (N = 57, Mage = 18.8, SDage = 0.94) were randomly presented with binaural beat stimuli, ranging from 1 to 50 Hz, as well as a pure tone stimulus while EEG was recorded. All participants evidenced a resonance profile with an average of 11.3 significant peak frequencies. Furthermore, the number of resonance peaks at each frequency within each canonical band was different from what would be expected by chance. Peak gamma frequency was identified to negatively correlate with conscientiousness (⍴ = -.32, p = .020), and peak alpha frequency negatively correlated with extraversion (⍴ = -.34, p = .024). These results suggest that binaural beats can effectively influence neural oscillatory behavior and may serve as a mechanism for modulating cognitive, affective, and social functioning.PsychologyBachelors of Science (BS
