Fremont Street: a walkable experience
No full textIn many cities and urban landscapes, streets have become functional corridors
for movement rather than cultural experiences. Streets, which were once the
heart of an urban community life, now lack the vibrancy and identity that make
a place truly memorable. The rise of uniform and commercial architecture,
commercial homogenization, and traffic-centric planning has stripped many
streets of their unique character and culture, leaving them for movement rather
than taking away their opportunities as spaces of engagement. The absence
of cultural celebration in city streets results in a loss of identity and a missed
opportunity to embrace the community. Instead of having great spaces that
reflect the diversity and collective history of the people who live there, many
streets feel disconnected from their sense of place. The opportunity to celebrate
heritage, creativity, and local traditions is often overlooked for improving poor
traffic conditions and profit-driven development. City streets should not only
serve as functional corridors but as living reflections of their communities.
This Project explores how intentional street design can create a dynamic sense
of place for young adults by fostering social interaction, cultural expression, and
sensory engagement. By integrating vibrant public spaces, diverse activities,
and pedestrian-friendly environments, urban streetscapes can cultivate identity,
belonging, and community among young adults, transforming everyday streets
into meaningful and immersive experiences.Thesis (B. Arch.)College of Architecture and Plannin
reTHINKING reUSE: a project exploration of adaptability and reSILIENCY
No full textMany cities have a growing number of abandoned buildings that have little
hope of being used again. What will happen to these once vibrant places that
have become increasingly forgotten? This thesis exemplifies how architectural
adaptive reuse can be implemented to revitalize a community and create a
conversation between a place’s past, present, and future.
Founded on the idea of unity, the City Methodist Church in Gary, Indiana was
once a community hub where thousands of people gathered, but it now lives
in ruins. This setting acts as a foundation for the project that aims to revive the
building’s history through new functions that better serve the contemporary
community. The new uses focus on ideas of making through both art and food
with an underlying agenda of learning. These programs bring the foundational
ideas of gathering and unity back into the framework of this place. This project
exists on a grid independent of the existing structure creating an interesting
dialogue that clearly contrasts the old and new forms. These two merging grids
allow for a flow between indoor and outdoor spaces that make the spaces come
alive to restore the character of this neglected place.Thesis (B. Arch.)College of Architecture of Plannin
Investigating the expression levels of APJ and SOX17 in the hypoxia gain-of-function embronic mouse hearts during the development of coronary vessels
No full textCoronary Artery Disease (CAD) is a significant contributor to global modality, with a
particularly profound impact in the United States. The intricate process of coronary aery
development begins with the formation of the endothelium during embryonic stages. Sox17 and
APJ signaling regulate compensatory coronary angiogenesis in the developing mouse heart.
Sox17 is hypothesized to stimulate endocardium-derived coronary angiogenesis, whereas APJ
mediates angiogenic signaling pathways essential for coronary growth from the sinus venosus.
Furthermore, hypoxia is also implicated as an important signal in mediating endocardiumderived
compensatory angiogenesis in APJ mutant heart. However, the interplay between APJ, hypoxia, and SOX17 signaling pathways in the regulation of coronary angiogenesis is not fully understood. In this study, we established a hypoxia gain-of-function mouse model system to investigate whether hypoxia interacts with APJ and SOX17 to regulate coronary
angiogenesis. We utilized the Nkx2.5Cre+ER inducible deletion Cre line and the vhl flox/flox
mouse line to delete the vhl gene in cardiac progenitor cells and early cardiomyocytes. By
depleting VHL protein and stabilizing Hif1alpha, this approach successfully mimicked hypoxic
conditions in developing mouse hearts. Our results demonstrated that HIF-1α protein levels were significantly (p<0.05) elevated in cKO samples, confirming the effectiveness of the hypoxia model. There was a significant downregulation of APJ
mRNA levels (p<0.05) and protein (p<0.05) expression and a trend showing upregulation of
SOX17 expression under hypoxic conditions. These findings support the hypothesis that
myocardial hypoxia modulates coronary vessel development by repressing APJ and potentially
enhancing SOX17 signaling. This study provides valuable insights into the molecular mechanisms
underlying coronary angiogenesis and highlights potential therapeutic targets for CAD.M.S
Curriculum reform-the case of an innovative laboratory school in a midsize med-western university
No full textThis dissertation investigated how a laboratory middle school’s new IMPACT curriculum promotes a personalized, engaging and practical student experience. This study was undertaken as a response to recent calls for curriculum reforms that emphasize student-centered modes of teaching, learning and creating knowledge. IMPACT is an acronym for Investigation, Metacognition, Passion, Actualization, Curiosity and Togetherness. The study also explored how IMPACT promotes 21st century skills such as critical thinking, creativity, collaboration and problem-solving in a democratic school culture as well as students’ perceptions about the program content and pedagogical approaches. The laboratory school develops, implements and reviews curriculum and instructional strategies regularly and subsequently shares these practices with other school districts to improve learning outcomes.
This single case study research design elicited the views of eleven (11) middle school students from the 6th -8th Grades, four (4) teachers and the director of academic innovation and community engagement. The data from teachers and the director was gathered through semi-structured interviews, lesson observation and email responses while data from students were gathered through semi- structured interviews and a focus group interview involving four (4) selected students. These were designed to assess the key elements and factors that make the curriculum personalized, practical and engaging along with student perceptions regarding their learning process.
Using Woods and Woods (2012) Degrees of Democracy Framework as a guide, the study determined that the IMPACT curriculum has a growth orientation as its goal. The findings also suggest that the mode of teaching and learning is inquiry-based with teachers collaborating and providing tailored support and feedback to individual students. It was also determined that the program promotes independent student study that emphasizes student interest which includes hands-on activities involving the creation of books, podcasts, documentaries as well as art and craft involving woodwork. Through IMPACT’s project-based learning (PBL) and interdisciplinary activities that connect them with real world issues and literature, students acquire 21st century skills such as critical thinking, creativity and problem-solving skills. On the flipside there was evidence to suggest that teachers and students encountered some challenges during the implementation of the IMPACT curriculum. These included problems with integrating Math within the program, mixed responses to the No Grades policy, resource constraints, dealing with the demotivated student as well as the inexperienced teacher challenge.Ph.

Bismuth-based heterostructured nanocomposite photocatalysts for the degradation of organic pollutants
No full textEnvironmental pollution poses a critical threat to both humans and ecosystems. This dissertation details the development of novel bismuth-based heterostructured nanocomposite photocatalysts aimed at degrading persistent organic pollutants (POPs), specifically targeting chlorinated organic compounds (VOCs) such as trichloroethylene (TCE) and systemic pesticides like glyphosate. The objectives of this work involve designing optimized photocatalysts that maximize photocatalytic efficiency under visible light for industrial applications and evaluating their degradation mechanisms. The methodological approach includes synthesizing various bismuth oxide photocatalysts, including bismuth vanadate, bismuth ruthenate, and their composites with palladium and carbon dots (CDs), as well as bismuth oxyhalides and their composites. Advanced characterization techniques, such as electron microscopy, X-ray diffraction, X-ray spectroscopy, UV-Vis spectroscopy, and photoelectrochemical analysis, are utilized to assess structural properties, charge dynamics, and photocatalytic performance. Chapter 1 establishes the foundation by defining organic pollutants, their classifications, and the urgent need for innovative treatment technologies. This introduction underscores the vital role of advanced nanomaterials in environmental remediation and highlights the potential of photocatalysis as a sustainable solution. Chapter 2 centers on the synthesis and characterization of a palladium-decorated bismuth ruthenate/bismuth vanadate (Pd@Bi2Ru2O7/BiVO4) Z-scheme heterojunction photocatalyst capable of degrading TCE. The results show a significant improvement in photocatalytic activity due to optimized electronic properties and enhanced charge separation mechanisms, resulting in nearly complete TCE degradation within a few hours under visible light. Chapter 3 examines the incorporation of carbon dots into Bi2Ru2O7/BiVO4composites (CD-Bi2Ru2O7/BiVO4) to facilitate greener enhancements in photocatalytic degradation of TCE. Experimental findings support the hypothesis of improved photocatalytic efficacy attributed to enhanced charge transport and extended light absorption, yielding improved degradation kinetics. Chapter 4 presents a study on the synthesis of an S-scheme heterostructured palladium-decorated bismuth vanadate/bismuth oxyhalide (Pd@BiVO4/BiOX, X = Br, Cl) photocatalyst, achieving synergistic effects between the juxtaposed materials, which create pathways that significantly optimize TCE and PCE degradation rates. Chapter 5 shifts focus to the rapid photocatalytic mineralization of glyphosate using palladium-decorated bismuth vanadate/bismuth oxybromide (Pd@BiVO4/BiOBr) nanosheets, outlining mechanistic insights into degradation pathways and comparative analyses with other conventional photocatalysts. In conclusion, the findings of this research highlight the transformative potential of bismuth-based photocatalysts in effectively addressing challenges related to persistent organic pollutants. Promising scalability projections emphasize their relevance for large-scale implementation in environmental remediation, ultimately contributing to improved water quality, public health, and a safer environment.Ph.

Agree or disagree: are women emotionally suited for politics? A classification analysis using cart and random forest
No full textThere is no shortage of research exploring the link between gender stereotypes and politics. The
present study attempted to contribute to this scholarship by using recursive partitioning
algorithms (CART and Random Forest) to identify the most important variables in classifying
whether someone agrees or disagrees that men and women differ in their emotional suitability for
politics. Using data from 251 respondents to the 2022 General Social Survey (GSS), results
revealed that traditional gender role ideology, as well as attitudes towards immigration and
abortion, are the most important variables for classification. The implications for voting— and
the underrepresentation of women in politics more generally— is a matter for future research.
Caution is advised when interpreting these results, given the weaknesses of the model discussed
herein.M. S
Building hope
No full textChild marriage remains a critical issue, driven by poverty and leaving countless
girls trapped in cycles of suffering. In male-dominated societies, girls are often
overlooked, making education often unaffordable, causing many families to
resort to marriage as a means of survival.
This thesis explores how architecture can become a transformative force in
breaking this cycle through a self-sustaining community in Chipinge, Zimbabwe.
The design addresses the needs of three key groups: the city, struggling
families, and girls at risk. A school offers education and empowerment,
reshaping how girls view their future. Housing supports families who choose
education over marriage, while a hospital and marketplace provide services for
both residents and the broader community. Additionally, coffee farming and job
opportunities strengthen economic independence. The buildings are unified by
lifted roofs, allowing natural light to filter in. Light-diffusing materials minimize
direct sunlight while still harnessing the benefits of daylight. Constructed using
modular techniques and locally sourced materials like bamboo, mud brick,
and sheet metal, the design remains replicable and maintainable. Sustainable
strategies, such as passive ventilation, solar energy, and rainwater collection,
and minimal site disturbance, ensure environmental balance and long-term
viability. This project demonstrates how architecture can create lasting change,
empowering young girls and transforming communities.Thesis (B. Arch.)College of Architecture and Plannin
Muscle-specific atrophy of the lower limb in response to microgravity exposure in women
No full textLong duration spaceflight missions and trips to explore Mars may require up to a year of microgravity exposure and will require astronauts to return to gravitational environments and carry out their duties. This will require adequate countermeasures, primarily through exercise training, to maintain all the physiological systems, including skeletal muscle. The aim of this study was to identify muscle-specificity within the skeletal muscle atrophy response to simulated microgravity exposure in women. Subjects (n=8 W) underwent bedrest with a 6° head-down tilt for 60 days, where skeletal muscle volume of 17 muscles within the lower limb was measured at baseline, one month (29 days), and two months (57 days). Muscle volume decreased (p0.05). Comparisons to men who completed similar bedrest and muscle volume measurement protocols identified that women experienced a larger magnitude of atrophy in 16 of the 17 examined muscles (p<0.05). Seven of the 17 muscles experienced at least twice the magnitude of atrophy compared to men. In summary, there is muscle- and sex- specific atrophy within the lower limb skeletal muscle response to microgravity. An understanding of these responses within the context of exercise countermeasure effectiveness is necessary to protect the health and function of women and men on future long-duration space missions.M.

A peer coaching adaptation of the collaborative model for promoting competence and success (compass)
No full textIn this study, a peer coaching adaptation of the Collaborative Model for Promoting
Competence and Success (COMPASS) was conducted to address the challenges faced by
underserved schools in providing evidence-based support for students with autism. COMPASS is
a proven consultation and coaching intervention, but accessibility barriers limit its
implementation in educational settings with low resources. COMPASS was adapted by
integrating a peer coaching approach, enabling special education teachers to implement the
intervention without reliance on trained consultants. A single-case research design was employed
to evaluate whether special education teachers could implement the peer coaching adaptation
with fidelity. Additionally, this study examined teachers' perceptions of the intervention's
feasibility, appropriateness, and acceptability, as well as the progress made by students with
autism on individualized social skills goals. Findings indicate variable results regarding teacher
coaching fidelity; one out of three teachers achieved 80% fidelity in implementing the adapted
COMPASS model. Teachers reported mixed results regarding the intervention's acceptability,
feasibility, and appropriateness, indicating varying levels of comfort and perceived utility in the
peer coaching adaptation. Despite this, students demonstrated meaningful progress on their
individualized social skills goals, with outcomes aligning closely with those observed in
traditional COMPASS implementations. These results suggest that a peer coaching adaptation of
COMPASS could offer a viable solution for increasing access to evidence-based interventions in
underserved educational settings, ultimately enhancing the support provided to students with
autism.Ph. D
My loved ones as landscapes
No full text“My Loved Ones as Landscapes” is a series of landscapes that draws inspiration from the impressionist and post-impressionist movements of art history. The primary goal of this body of work was to express my love for those I am closest to through metaphorical representations, imagery, movement, color, and emotion. Each landscape painting represents a different individual in my life, and I plan to give away the paintings to each of the individuals I have chosen to representationally depict. For each painting, I have put a lot of thought into making the piece an intentional, personal gift that pays homage to the individual I am depicting. This project is very meaningful to me because I have found a lot of joy and fulfillment in preparing to give these gifts to those I love. For my last studio project at Ball State University, I am excited to share this body of work that depicts the unique relationships I have with each of the people I am closest to, and to give these pieces of artwork to my biggest supporters.B.
