Healing From the Harms of Schooling
Get PDFIn Circles de Confianza (CdC), Latinx youth from a suburban, predominantly White high school, gathered to pause, reflect and collectively engage in radical healing practices to heal from experiences of desconfianza (harms) of schooling and take action to prevent future harms. Healing is conceptualized as 1) rooted in Indigenous and/or People of Color-developed frameworks, 2) emphasizing the importance of individualized AND collective healing, and 3) addressing the harms of systemic oppression. This study is based on research conducted with the Belonging and Trust research team based in the Renee Crown Wellness Institute at the University of Colorado at Boulder. Methods included testimonio, photovoice, photoethnography and multimodal testimonio. The practices of healing, pláticas and desahogando, are rooted in Curanderisme wisdom and serve as examples of how Indigenous people have responded to oppression and historical trauma over generations. My research questions are: 1) How are students describing their experiences of harm and/or trauma in their schooling experiences? What did students say they were healing from? What were the “traumas/harms” that they described?; 2) How did students describe their experience with the Circles de Confianza space?; and 3) How did students take action to reduce harms in schools as a result of their experience with CdC?
Findings show that the stories of desconfianza fell into four categories: invisibilizing students in learning environments by not learning their names; the practice of placing academic expectations on students based on their racial, ethnic, linguistic backgrounds and/or national origins; harmful experiences of cultural incompetence and tokenization; harms of enduring years of schooling curriculums excluded substantive contributions of BIPOC people. Congruent with Teeters et. al. (2023a, 2023b), the CdC space was healing for students. Through pláticas and processes of desahogando we held space that allowed for radical healing to occur. Student-led actions influenced district-wide change and students engaged in exercises to radically imagine “schools de confianza”. CdC offers a case study of a school-based radical healing program that provides the field of Youth Organizing studies and the Learning Sciences with an example of what healing practices in activism spaces can look and feel like.</p
Quantitative Dielectric Spectroscopy and Crystallography of Roto-Electric Crystals
Get PDFA roto-electric crystal is a novel, synthetic material that contains rotatable, electric dipoles on a lattice. The dipoles are molecular groups with a built-in permanent polarization that are able to rotate on axle-like carbon-carbon bonds. The 2D triangular lattice of rotatable dipoles is predicted to have a ferroelectric ground state with unique properties that could enable the design of tunable resonant circuits at a nanoelectronic scale. Our modular approach to material design utilizes a hexagonal host crystal, with open channels, to trap rotor molecules (containing the rotatable electric dipole), forming rotor inclusion compounds. Previous work has been done with rotor inclusions in powdered form, which allowed the group to quantify the lattice parameters with X-ray scattering and barriers to rotation through dielectric spectroscopy. This thesis seeks to progress our understanding of the dipole-dipole coupling and how the dipoles contribute to the overall dielectric response through two physical refinements: (1) fixing two dipole-rotators on each included rotor molecule to constrain the intra-channel distances between pairs of rotators in the channels, and (2) growing channel aligned, crystalline thin films. The nature of the host crystal leads to two distinct 9-state models for pairs of dipoles that predict different behaviors depending on the dipole-dipole distances. Thin films are grown with aligned channels as confirmed by grazing incidence X-ray experiments, constraining rotations to the plane of the substrate. By measuring the thickness of the films, the dielectric constant can be extracted from capacitor measurements, allowing us to quantify the contribution rotors make to the dielectric properties.</p
High Throughput Mechanistic Modeling for Electrocatalyst Materials Discovery
Get PDFElectrocatalysis is a key technology to enable the transition to a circular chemical economy with low-carbon chemical feedstocks and energy sources. The reduction of N2 to NH3 via the Haber Bosch process is critical to global food security, but also emits close to 2% of total carbon emissions. While there are multiple proposed alternatives to Haber Bosch, the aqueous electrochemical reduction of N2 stands out as the most distributable technology. To date, there have been no experimental demonstrations of cost-competitive nitrogen reduction catalysts due to the competition with the hydrogen evolution reaction. Theoretical modeling is necessary to down select sparse chemical spaces to find promising nitrogen reduction catalysts because full experimental exploration is intractable. I used grand-canonical density functional theory to model the electrocatalyst interface and develop design principles that can be used to optimize electrochemical nitrogen reduction. The results of my mechanistic modeling informed materials screening studies, which yielded specific material design recommendations. The data generated during modeling was processed and uploaded to a publicly accessible database, BEAST DB, which allows users to explore reactivity across catalyst chemistries. Finally, to support more advanced theoretical calculations and increase throughput, I added JDFTx support and job recipes to Atomate2, a Python library for automating high throughput materials science.</p
Feminist Spatial Politics
Get PDFIn Feminist Spatial Politics, I offer an explicitly spatial analysis of feminist activism that contests material spaces–buildings, infrastructures, and city layouts– to theorize an answer to a deceptively straightforward question: Why should feminists think politically about material spaces? Framing freedom, feminism, and material spaces as dynamic processes that are intertwined with one another, I contend that a spatially-oriented feminist politics can facilitate the exercise of political freedom and renew feminist visions. I argue, first, that material spaces should be intentional subjects of feminist activism. Feminists have documented the ways in which buildings and infrastructure constrain women’s participation in social and political life, circumscribe their movements, limit their sense of agency, or otherwise uphold sexist oppression. I reveal that when feminist activists contest these spaces, they reconfigure them from oppressive structures to feminist tools, means through which feminists can advocate for social and political change. Second, I contend that a spatially-oriented feminist politics expresses and extends feminist freedom–the ongoing political practice to end sexist oppression through envisioning new social and political worlds and speaking and acting with others to work toward those visions. Spatial contestation develops the political capacities and skills necessary for the exercise of feminist freedom.
I develop this argument through an analysis of select case studies representative of four modes of feminist spatial contestation: the Women’s Social and Political Union’s destruction of patriarchal spaces, debates about infrastructure reform such as women’s-only transportation, the political placemaking of a group of marginally-housed Black mothers, and feminist institution building. Through each case, I show that feminists exercise judgments about gendered spaces and feminist tactics, dialogue through disagreements, and act on feminist spatial visions, ultimately opening new avenues for political action and inspiring imaginative feminist visions for our future world. This dissertation provides a necessary intervention in feminist literature that conceives of spaces largely as oppressive structures that contribute to women’s unfreedom. Reorienting feminist thinking about spaces toward freedom, I argue that feminists should think politically about material spaces not because they have constrained us in the past, but because a spatially-oriented feminist politics can open new possibilities for feminist futures.</p
Form and Function of Male Lament in Euripidean Tragedy
Get PDFThis dissertation examines the depiction and language of male lament in three plays of Euripides: Hippolytus Suppliant Women, and Andromache. Scholarship has traditionally viewed lament as the province of women in Greek literature, interpreting male lament as either a sign of weakness or effeminacy or an appropriation of a female genre. Combining close reading and content analysis with theories of gendered speech, I argue instead that male lament in Euripidean tragedy is neither emasculating nor contrary to expected behavior for ancient Greek men. Rather, as a literary representation of real funerary practices, male lament serves to reintegrate and reestablish the lamenter into his community.
The first chapter examines two male laments in Hippolytus (Theseus at 811-885 and Hippolytus at 1347-1388). I show how Theseus’ lament is presented as expected and normative, and furthermore highlights his connection to the chorus and thus the greater state. In contrast, Hippolytus’ lament is framed as anomalous, caught between male and female elements. As such, it highlights his disconnect from the community and its ideals. The second chapter considers Suppliant Women and its laments, which have previously been used to argue in favor of reading lament as inappropriate for men. I challenge this view by showing that these readings are more tenuous than previously thought and that the male laments of the play can be read as necessary representations of public and private funeral ritual within the dramatic narrative. The third chapter discusses the laments of Peleus and Hermione in Andromache (lines 1173-1225 and 825-865, respectively), showing how they are juxtaposed against one another. The male Peleus and his lament are portrayed as the correct and moral counterpart to the female Hermione and her inappropriate perversion of the genre.
Ultimately, this study shows how male lament is presented within the realm of tragedy as an acceptable and restorative action. When performed in the proper manner, it facilitates the restoration of the natural order and heals the damage to society caused by death. Far from emasculating the performer, male lament instead enables him to validate his identity and reconnect him to society.</p
Recreation Demand Estimation and Good Valuation
Get PDFThis dissertation contains three chapters analyzing recreation demand and the valuation of public goods using novel datasets. In the first chapter, I examine consumer substitution behavior in response to an access fee, finding that fee-induced declines in visitation do not necessarily lead to increased usage of alternative, free-access sites. My findings suggest that certain environmental goods, such as mountains, may be more differentiable than previously recognized. The second chapter estimates residents’ willingness to pay for campgrounds across Arizona using a travel cost model and administrative data. Previous travel cost studies have relied on survey data and assumed that administrative data are unreliable; however, I demonstrate that administrative travel cost data can serve as a viable alternative to survey-based valuation methods, enabling large-scale analyses at the state level and beyond. Finally, the third chapter compares two willingness to pay estimation methodologies: discrete choice experiments and direct questioning methods. I partnered with the City of Chandler, Arizona, to estimate willingness to pay for city aquatic programs, such as swimming lessons, using both methods. While I found no evidence that discrete choice experiments produce biased estimates, I identified that direct questioning methods may be susceptible to price anchoring bias. Collectively, these studies contribute to the understanding of non-market valuation, pricing strategies, and consumer behavior in natural resource management, with direct implications for public policy, land management, and municipal program pricing.</p
Hombres de papel: estrategias narrativas para desarticular la masculinidad hegemónica en Bolaño, Lemebel y Eltit
Get PDFEsta tesis examina cómo las narrativas literarias de Roberto Bolaño, Pedro Lemebel y Diamela Eltit exploran y desafían la masculinidad hegemónica en el contexto de producción de la dictadura y postdictadura chilena. El análisis parte de la hipótesis de que las obras de estos autores revelan la masculinidad no como una esencia inmutable, sino como una construcción precaria, sostenida por la reiteración performativa y fracturada por resistencias marginales. El primer capítulo se centra en la obra de Roberto Bolaño, específicamente en Estrella distante (1996), Nocturno de Chile (2000) y 2666 (2004), donde se analizan los personajes masculinos que internalizan y reproducen los mandatos del patriarcado, manifestados en la represión emocional, la homosocialidad excluyente, la cosificación de los cuerpos femeninos y la violencia estructural. Se estudia cómo la narrativa de Bolaño presenta estos procesos como una escalada gradual, desde la indiferencia emocional hasta la violencia explícita, confrontando al lector con las consecuencias devastadoras de la masculinidad hegemónica y sus mecanismos implícitos de normalización. El segundo capítulo aborda la obra de Pedro Lemebel, incluyendo las colecciones de crónicas Loco afán: crónicas del sidario (1996), Háblame de amores (2012), Poco hombre (2013), y la novela Tengo miedo, torero (2001) donde se explora la forma en que Lemebel retrata la violencia y exclusión ejercidas por la dictadura chilena hacia las comunidades sexo-disidentes, visibilizando y cuestionando la marginación sistemática. Su narrativa, híbrida entre lo testimonial y lo poético, redefine la masculinidad desde una perspectiva afectiva y comunitaria y muestra cómo la empatía crítica, la solidaridad entre excluidos y una performatividad alternativa del género pueden subvertir profundamente las normas patriarcales dominantes. El tercer capítulo se dedica a Diamela Eltit y analiza las novelas El cuarto mundo (1988), Los vigilantes (1994), Jamás el fuego nunca (2007) y Fuerzas especiales (2003), donde se estudia cómo Eltit desmantela las estructuras discursivas patriarcales mediante técnicas narrativas que fragmentan el orden temporal, marcan las fronteras entre los espacios públicos y privados, y cuestionan profundamente las representaciones simbólicas de la masculinidad. Sus textos revelan la fragilidad oculta detrás del dominio patriarcal, subvirtiendo las expectativas tradicionales sobre género y poder, y presentando la masculinidad como un constructo precario y susceptible a la resistencia. Finalmente, este estudio ofrece una contribución crítica al debate actual sobre la configuración y representación de las masculinidades en América Latina. Al explorar cómo Bolaño, Lemebel y Eltit exponen, cuestionan y reconfiguran la masculinidad hegemónica, se aporta una perspectiva interdisciplinaria que conecta literatura y estudios de género, lo que resalta la relevancia de las narrativas literarias como espacios clave para interrogar y transformar los mandatos patriarcales en contextos marcados por la violencia y la exclusión.This thesis examines how the literary narratives of Roberto Bolaño, Pedro Lemebel, and Diamela Eltit explore and challenge hegemonic masculinity within the context of production of the Chilean dictatorship and post-dictatorship periods. The analysis is grounded in the hypothesis that these authors’ works reveal masculinity not as an immutable essence, but as a precarious construction, sustained by performative reiteration and fractured by marginal forms of resistance. The first chapter focuses on the works of Roberto Bolaño, specifically Estrella Distante (1996), Nocturno de Chile (2000), and 2666 (2004), analyzing male characters who internalize and reproduce patriarchal mandates, manifested through emotional repression, exclusionary homosociality, objectification of female bodies, and structural violence. Bolaño’s narrative presents these processes as a gradual escalation, progressing from emotional indifference to explicit violence, thereby confronting readers with the devastating consequences of hegemonic masculinity and its implicit normalization mechanisms. The second chapter addresses the work of Pedro Lemebel, including his chronicle collections Loco afán: crónicas del sidario (1996), Háblame de amores (2012), Poco hombre (2013), and the novel Tengo miedo, torero (2001). This chapter explores how Lemebel portrays the violence and exclusion inflicted by the Chilean dictatorship on sex-dissident communities, making visible and critically questioning their systematic marginalization. His narrative, hybridizing testimonial and poetic forms, redefines masculinity from an affective and communal perspective, demonstrating how critical empathy, solidarity among marginalized groups, and alternative gender performativity can profoundly subvert dominant patriarchal norms. The third chapter is dedicated to Diamela Eltit, analyzing her novels El cuarto mundo (1988), Los vigilantes (1994), Jamás el fuego nunca (2007), and Fuerzas especiales (2003). It examines how Eltit dismantles patriarchal discursive structures through narrative techniques that fragment temporal order, delineate boundaries between public and private spaces, and deeply question symbolic representations of masculinity. Her texts reveal the concealed fragility underlying patriarchal dominance, subverting traditional expectations concerning gender and power, and presenting masculinity as a precarious construct vulnerable to resistance. Finally, this study provides a critical contribution to contemporary debates on the construction and representation of masculinities in Latin America. By exploring how Bolaño, Lemebel, and Eltit expose, question, and reconfigure hegemonic masculinity, it offers an interdisciplinary perspective connecting literature and gender studies, thereby emphasizing the significance of literary narratives as key spaces for interrogating and transforming patriarchal mandates within contexts marked by violence and exclusion.</p
Macrocyclic Ligand-Driven Unprecedented Porosity in Electrically Conductive MOFs
Get PDFElectrically conductive metal−organic frameworks (EC-MOFs) integrate porosity and tunability with electrical conductivity, making them highly promising for electrocatalysis, energy storage, and electronic devices. However, the field is hindered by a limited selection of well-suited ligands, leading to limitations such as low surface areas, lack of functionalization, and moderate conductivity. Addressing these limitations, macrocyclic ligands offer a unique platform by providing enhanced porosity, additional functionality, and more efficient charge transport within these frameworks.
Section 2 presents a new EC-MOF constructed from the conjugated macrocyclic ligand HHTC (2,3,8,9,14,15-hexahydroxytribenzocyclyne) and copper nodes. This material exhibits good conductivity and a remarkably large surface area. The study of particle size tunability reveals particle size-dependent properties. The intrinsic alkyne-based pocket allows for heterometallic incorporation, expanding the framework's functionality. This work introduces a new ligand design for EC-MOFs, offering new opportunities for electronic applications requiring both high surface area and functionality.
Section 3 builds on the success of Section 2 by introducing the macrocyclic ligand EP (ethynylphenanthrene), which has a larger intrinsic pocket. When coordinated with copper nodes, Cu-EP achieves good conductivity, concurrently setting a record surface area for 2D EC-MOFs. Its combination of high surface area, spacious pocket, and inherent redox activity enhances capacitive performance. Furthermore, EP’s intrinsic pocket selectively hosts Cs⁺ over Li⁺, demonstrating potential for ion selectivity. This expansion of macrocyclic ligand diversity paves the way for applications requiring a unique combination of redox activity, ion selectivity, and a high surface area.
While Sections 2 and 3 demonstrate how macrocyclic ligands can enhance surface area and introduce extra functionality, a key challenge remained—achieving efficient charge transport without compromising porosity. Section 4 addresses this challenge by introducing Ni-HATC as a nanoporous synthetic metal that combines metallic charge transport with high porosity. The amino-functionalized macrocyclic ligand, HATC (2,3,8,9,14,15-hexaaminobenzocyclyne), enables both high porosity and efficient charge transport when coordinated with Ni nodes. Ni-HATC not only offers a next generation EC-MOF, but provides valuable insights into the relationship between molecular design and electronic properties.
Overall, this dissertation establishes macrocyclic ligand design as a powerful strategy to overcome key challenges in EC-MOFs. By enabling enhanced porosity, imparted functionality, and promoted charge transport, this work expands the scope of EC-MOF designs and introduces promising porous electronic materials for various electronic applications.</p
