Description
The Pennsylvania Department of Education recently adopted the new academic standards for Science, Technology & Engineering, and Environmental Literacy and Sustainability (STEELS). Scaling STEELS across the commonwealth is a challenging endeavor that depends upon local school districts' implementation of STEELS-based instruction. Therefore, it behooves local school districts to develop strategies supporting local STEELS adoption. The current action research study examined the influence of an intervention built around a Professional Learning Community (PLC) to support a local school district’s implementation of STEELS guided by the Concerns Based Adoption Model (CBAM; Hall & Hord, 2020). Four secondary science teachers from the Bellwood-Antis School District participated in a PLC. The implementation process of the PLC group was measured via the three diagnostic dimensions of CBAM: Innovation Configurations (IC), Stages of Concern (SoC), and Levels of Use (LoU). A concurrent mixed-methods action research design was employed to collect and analyze CBAM measures. The SoC dimension was measured quantitatively via the Stages of Concern Questionnaire. Individual scores were converted to a whole-group PLC SoC Profile for analysis. SoC, LoU, and IC dimensions were assessed qualitatively via semi-structured interviews. Meta-inferences were developed from combined data analysis of quantitative and qualitative data. A CBAM diagnosis for the PLC group was the primary outcome of this action research cycle, which indicated that the PLC members moved into the early phases of implementation during the intervention. Findings from the current cycle of action research informed an updated intervention game plan to be used in the next phase of implementation.

Description
This dissertation examines the dynamics of research-practice partnerships (RPPs) through a qualitative multiple-case study that explores the boundary work between university researchers and K-12 practitioners. It is framed within Wenger’s communities of practice theory and focuses on the concept of ‘boundary work,’ which is pivotal in understanding the collaboration and knowledge exchange in these partnerships. The study is titled “A Tale of Two Brokers” reflecting the critical role of individuals who bridge the divide between academic and practical spheres. It argues that the concept of boundary work is critical in understanding and improving the functioning of RPPs, suggesting that more attention should be paid to the role of brokers in facilitating these partnerships. Key findings reveal that effective boundary work in RPPs is contingent on mutual respect, shared goals, and a deep understanding of each community’s values and practices. The study highlights that while researchers and practitioners often have different priorities and approaches, successful brokers can harmonize these differences to create a productive partnership. These brokers often possess qualities such as flexibility, strong communication skills, and a deep understanding of academic and practical contexts.
In conclusion, this study contributes to the broader understanding of how university researchers and K-12 practitioners can effectively collaborate. It underscores the importance of recognizing and nurturing the role of brokers in RPPs, providing valuable lessons for future collaborations between academic researchers and practitioners in various fields.

Description
A high percentage of Native Hawaiian and other Pacific Islander (NHPI) adults (37.4%) aged 18 and older did not see a doctor in the past year. This is the highest percentage among all racial groups. Furthermore, approximately one in eight NHPI adults (12%) are uninsured, a rate that is markedly higher than Whites. Federal reports historically struggle to capture data that could explain these phenomena. Hence, NHPI are insufficiently and incompletely represented in health statistics, access health services at lower rates, and are insured at lower rates than other racial and ethnic minority groups. This has implications for perpetuating adverse mental health conditions and mental health disparities that are prevalent in this community (e.g., depression, anxiety, alcohol use disorder, and tobacco use), particularly following the global COVID-19 pandemic. The overarching goal of this research is to improve and broaden understanding of novel multi-level health determinants causing low mental health care service utilization rates of NHPIs, a presently understudied health disparity for Native Hawaiians and other Pacific Islanders in the U.S. Design: A closed access, cross-sectional Internet survey was used to collect data. Participants were recruited with announcements distributed nationwide via email to NHPI organizations, associations, and networks across the United States and social media. The sample included 395 NHPI adults aged 18 and older. Analysis: Latent profile analysis (LPA) were conducted using Mplus 8 statistical software to examine whether different conceptually meaningful profiles of NHPI Islanders emerge based on hypothesized health determinants measuring Symptom Distress (Perceived Health Status, Depression/Anxiety, and Perceived Stress), Protective Factors (Pacific Cultural Efficacy, Religious Centrality and Embeddedness, Pacific Connectedness and Belonging, and Perceived Societal Wellbeing) and Health Attitudes (Medical Mistrust and Service Provider Preferences [i.e., Traditional/Native Healer vs Medical Doctor/Nurse]) while accounting for demographic covariates (e.g., education, income, and insurance status). Results supported a four-profile model solution, where four distinct groups (named “Very Low Symptomatic,” “Low Symptomatic,” “Moderate Symptomatic,” and “High Symptomatic”) of participants demonstrated varying levels of symptom distress, endorsement of protective factors, and health attitudes. Furthermore, planned mental health care utilization was analyzed as an outcome variable, demonstrating varying levels of planned mental health service utilization across the four profiles. Significance: Findings may inform public policy and healthcare professionals about how to meaningfully engage NHPI communities in culturally competent mental health care services.

Description
This dissertation examines microevolutionary changes in the Eastern Adriatic and hinterland during Roman imperialism, evaluating changing patterns of variation among indigenous groups with varying histories of acceptance or defiance to Roman rule. Despite the prevalence of Roman influence, trade, and the accommodating nature of Roman political authority administered through existing local leaders, Eastern Adriatic and hinterland peoples underwent significant cultural transformations. Unlike the Roman-allied Liburnians, Romanization was not a voluntary and amicable process for the resisting Delmatae, Histri, Japodes, and Pannonians. The violent experiences of locals during the late Republican Period and early Roman Empire, including death, enslavement, conscription, and displacement, contrast with the eventual integration of the region by the end of the Roman Empire, when their descendants were Roman citizens. These complex histories make it challenging to understand local identities and the impact of Romanization. Biological distance analyses of dental morphology from Liburnian, Delmatae, Japodes, and Pannonian samples representing 313 individuals dating to the Iron Age (c. 700- 400 BCE), and Roman Period (Roman Republic c. 200- 0 BCE; Roman Empire c. 1- 500 CE), were contextualized with archaeological data and classical research. Results indicated no significant differences within Eastern Adriatic and hinterland populations across the time periods. However, interpretations of the results for Roman Period Liburnians, descendants of Roman allies, suggest differentiation from contemporaneous Italic Romans. Conversely, the descendants of resisting populations were not statistically different from Roman Empire Italics, potentially influenced by their ancestors’ experiences of war affecting subsequent admixture, community formation, and adherence to prevailing norms.
Roman laws that managed access to advantageous status identities through marriage and citizenship may also explain the findings that all surveyed local populations demonstrate continuity between ancestors and descendants. The dynamic of being identified as Roman, and yet descending from the people who fought against Rome, is further discussed as a form of biological imperialism, consequentially shaping indigenous ancestral ties within a pan-regional Roman citizenry. While Roman multiculturalism is often considered exemplary of Antique Period diversity, Roman values prioritized diversity when it was advantageous and used pluralism to encourage cultural assimilation and define outsiders.

Description
Southern United States English (SUSE) is North America’s most stigmatizedregionalized dialect, leading to generational decline and underrepresentation from
characters in primetime television. This study explores the representation of SUSE
features by 80 local news broadcasters in eight Southern affiliates, all outside major
metropolises. This sociophonetic study surveys the PIN-PEN merger and Stages I and II
of the Southern Vowel Shift (SVS) — /aɪ/ glide weakening and /e/-/ɛ/ proximity. The PIN-PEN merger was found to be widespread among broadcasters, with
49/80 (61%) having a PIN-PEN Pillai score less than 0.3, considered “merged”. /aɪ/ glide
weakening was subtly present, despite being a marked SUSE feature: /aɪ/ was
overwhelmingly diphthongal, but the median and Q3 variants (measured in Euclidean
distance from 20% to 80% duration) ended in the lower half of the vowel space, showing
a general lack of glide raising. Lastly, /e/-/ɛ/ proximity had marginal representation: Only
11/80 (14%) broadcasters had a non-sonorant /e/-/ɛ/ Pillai score less than 0.45, and the
median Pillai score was 0.664, establishing that an advanced SVS is not typical. The best predictors for the PIN-PEN merger were attending a Southern college,
being African American, and being male — all factors of socialization. Contrastingly, the
(mutually exclusive) best predictors of /aɪ/ glide weakening were more products of
stylization — occupational role and the subregion that hired the broadcaster (whether the
audience was a ‘Deep South’ market). For /e/-/ɛ/ proximity, the interaction of gender and
Southern college attendance was statistically significant, as only men with Southern
college backgrounds generally had this apparently stigmatized feature. Age was not found to be significant for any feature, subverting expectations that
younger speakers keep SUSE at ‘arm’s length’. TV market size was impactful for each
feature but repeatedly (narrowly) missed the p=0.05 threshold for statistical significance.
Sports anchors led in SUSE forms for each feature, showing SUSE as an asset;
investigative reporters, however, had the least SUSE /aɪ/ and /e/-/ɛ/ variants. Gender had
strong explanatory power for each feature, inferring that men tended to ‘lean in’ to
SUSE’s positive solidarity traits, but women tended to incorporate SUSE less often due
to its negative competency traits.

Description
When Black women step into leadership roles, they confront well-documented organizational obstacles that hinder their progress. Existing research indicates that they experience differential treatment due to their intersectional identity as Black females, and these hindrances significantly impede their path to success. To increase the success of Black women in leadership roles, they need to be supported by professional development dedicated to strengthening their leadership self-efficacy. Through the theoretical lenses of intersectionality and the glass cliff phenomenon, this study investigates how an arts-based sister circle model impacts the leadership self-efficacy of Black women in leadership positions within the arts and culture sector in predominantly white organizations. Using an arts-based Experiential Learning Theory paradigm, this mixed-methods participatory action research design incorporated three virtual sister circle meetings, a participant interview, and a pre- and post-Leadership Self-Efficacy survey. Qualitative data also included digital journals, artistic reflections, and word clouds. I invited participants to join based on the following criteria: (a) Black woman, (b) manager or administrator, (c) working in a predominately white arts and culture organization such as a community arts school, art gallery, or music organization, and (d) commitment to engage in online and workplace learning experiences. Five participants throughout the United States began the study, though only two completed the innovation due to attrition connected to their work. Assertions deduced from the results were: (1) Black women face many challenges when promoted into leadership positions in predominantly white organizations, driving them to seek opportunities to network and create community with other Black women leaders; (2) Sister Circle meetings serve as community spaces providing opportunities for deep conversation and problem-solving without fear of retribution about the social, cultural, and emotional challenges they face as Black women leaders in their organizations; and (3) Participation in Sister Circle meetings may enhance leadership self-efficacy and career development and positively impact work-life balance. Survey results reinforce the sister circle model's positive influence on Black women. The findings collectively suggest that sister circles, as a coaching model, fulfill a crucial role in addressing the nuanced needs of Black women in leadership positions.

Description
Functioning freshwater ecosystems are widely recognized as a planetary boundary for the continued human inhabitation of our planet, but little is known about the tradeoffs at the nexus of food, energy and water. In this dissertation I explored the effects of hydrologic variability in the Lower Mekong Basin (LMB) on rice production and functional structure of fish catches. I then examined the tradeoffs at the intersection of fish and rice harvest as a function of hydrologic variability and modeled production under novel engineered hydrologic scenarios. I modeled rice production using a Multivariate Autoregressive State Space (MARSS) model and mechanistically tested for the effect of saline intrusion. I found rice production to be heterogeneously affected by hydrology; in saline afflicted areas, floods had a positive effect size on production, whereas in non-saline afflicted areas, floods had a negative effect size on production. To address hydrologic filtering of the functional structure of fish catches, I collected thousands of specimens from over 100 LMB species in collaboration with Cambodia’s Inland Fisheries Research and Development institute and the Royal University of Agriculture. LMB fishes comprise a large portion of the 1,200 known species in the basin and have historically provided a substantial amount of animal protein to 60 million people in the region. Using an RLQ, co-inertia analysis, I found four functionally relevant morphological trats that were significantly associated with hydrologic variation—mouth position, maxillary length, relative body depth, and relative head depth. These traits are associated with many of the threated species in the LMB, which make up a large portion of the 1200 known species in the basin and have historically provided a substantial amount of animal protein to 60 million people in the region. To examine the tradeoffs within food systems, I used MARSS maximum likelihood estimation to forecast fish and rice production throughout the LMB under different hydrologic scenarios. I end my dissertation with an opinion piece on NexGen Mekong Scientists, a program I started in 2020 with funding from the United States Department of State.

Description
The U.S. Department of Agriculture’s (USDA) National School Lunch Program and School Breakfast Program provide nutritious meals to school-age children. USDA’s Community Eligibility Provision (CEP) is designed to extend the reach of these programs by allowing schools in low-income areas to provide free school meals to all students at no cost to families. CEP has been shown to increase school meal participation, nutritional intake, academic achievement, and attendance in previous research studies. This study aims to examine the impact of long-term CEP participation on student weight outcomes. Nurse-measured height and weight data for school years 2013-14 to 2019-20 were collected from 141 K-12 public schools in four low-income cities. School-level prevalence of obesity was calculated from students’ heights and weights using the Centers for Disease Control and Prevention protocol. CEP participation for each school year was obtained from the state Department of Education. Schools in the sample began participating in CEP at different times yielding varying numbers of years of CEP exposure over the study period. Multivariable analyses examined the relationship between school CEP exposure and the prevalence of obesity, controlling for school-level covariates. Multivariable analyses showed that for every additional year of CEP participation, the school-level prevalence of obesity was 0.4% lower (p=0.018). The regression-adjusted obesity prevalence for schools that never participated in CEP was 28.0%, while the obesity prevalence for schools with 6 years of CEP participation was 25.4%. The lower prevalence of obesity in CEP-participating schools was primarily driven by elementary schools. These results suggest that the benefits of CEP participation can cumulate over time, significantly reducing school-level obesity prevalence over time.

Description
Amidst mounting global crises spanning environmental, social, and economic domains, sustainability education has emerged as a vital pathway toward a thriving future. However, despite its promise, the concept of sustainability often remains superficial, leaving educators ill-equipped to address its complexities. While efforts to integrate sustainability into education are underway, critical pedagogy, a crucial tool for fostering social change, is notably absent from instructional practices. This action research project utilized critical pedagogy to design and implement a critical professional development (CPD) workshop within a larger fellowship program to center justice within sustainability in both content and pedagogical approach. As a result, participants’ definitions and understandings of sustainability increased across all measurements of extent, breadth, and depth. Specifically, participants redefined collaborative relationships and more prominently included notions of justice and equity in their conceptualizations of sustainability and sustainability education. The use of critical pedagogy encouraged teachers to analyze intersectional oppressive systems and fostered a new, critical perspective on sustainability. In their own educational designs, participants demonstrated an intention to model elements of critical pedagogy, such as dialogic action and permeable content. Finally, in alignment with the intended outcomes of CPD, participants developed cooperative space for co-learning, built unity, shared leadership, and felt confident implementing their own professional development to address context-specific concerns. By using critical pedagogy in sustainability education, the workshop participants prioritized deep and caring relationships which fostered empathic engagement with the intersectional and often dehumanizing systems that have led to interconnected global crises. The results indicated that using CPD as a framework could be effective in teacher professional development for sustainability as a design and implementation tool to center critical work that examines systemic issues of injustice and exploitation against both humans and our planet.
