Ni De Aqui, Nor There. Pero As The In-Between, Vanessa Franquez

College of Graduate Studies: Theses & Dissertations

This thesis explores first-generation Mexican American identity as a lived experience of translation and survival. Drawing from Judith Butler, Gloria Anzaldúa, and Jack Burnham, the work frames identity as performative, embodied, and shaped by overlapping cultural systems. Insects function as models of adaptation, camouflage, and defense, paralleling survival strategies such as code-switching and cultural hybridity. Through sculptural processes including tufting, felting, sewing, layering, and the inscription of Spanglish text, repetition and puncture become material metaphors for pressure, repair, and resilience. Language operates as both subject and substance, resisting grammatical purity in favor of hybridity. The work ultimately positions the in-between …

Fur-Ever In Memory: College Student Grief And Coping After Pet Loss, Rohit Paruchuri

College of Graduate Studies: Theses & Dissertations

Pet loss is a significant yet often overlooked form of bereavement, particularly among college students who are navigating emerging adulthood. Pets play an important role serving as a source of emotional support and are often viewed as family members; however, grief following pet loss is a type of disenfranchised grief, meaning it is not accepted by the society as something significant and often overlooked when compared to grief following human loss (Spain et al., 2019). Research suggests that grief following pet loss can mirror responses to human loss including sadness, guilt, loneliness, and disruption of daily routines (Eckerd et al., …

From Panels To Power: Empowering Middle Schoolers Through Comics, Ali Geigerman

College of Graduate Studies: Theses & Dissertations

This dissertation explores how craftivism, grounded in feminist theory and informed by multiliteracies, can be used to disrupt and reclaim the traditionally male-dominated genre of comics for girls and non-binary students. While the New London Group’s concept of multiliteracies expands definitions of literacy to include visual, spatial, and multimodal forms of meaning-making, it does not fully address questions of power, representation, and voice. Drawing specifically on the work of bell hooks as a theoretical anchor, this study positions comics not only as legitimate multiliterate texts but also as sites of feminist intervention. By blending multiliteracies, feminism, and craftivism, this research …

Effects Of A Context-Based Intervention On Sidelining Teacher Bias Toward Students With Attention-Deficit/Hyperactivity Disorder, Marisa Kortright

College of Graduate Studies: Theses & Dissertations

Students with Attention-Deficit/Hyperactivity Disorder (ADHD) often display behaviors such as inattention, impulsivity, and hyperactivity that may be perceived as disruptive in classroom settings. These behaviors can influence teachers’ responses and disciplinary decisions, which may be shaped by stereotypes or biases associated with ADHD diagnoses. This study examined whether a context-based intervention could reduce bias in teachers’ disciplinary decisions. Participants were 112 current or former elementary school teachers living in the United States who were recruited through the online recruitment platform Cloud Research. Using an experimental design, participants were randomly assigned to a neutral or empathetic intervention condition and evaluated student …

Formalizing Asymmetric Control-Telemetry Separation In Distributed Industrial Control Systems, Andrew Manison

College of Graduate Studies: Theses & Dissertations

Distributed industrial control systems often place control and telemetry traffic on the same communication substrate even though the two workloads impose different requirements. Control paths need bounded request-response latency and predictable acknowledgement semantics, whereas telemetry paths benefit from scalable publish-subscribe fanout and tolerance for consumer-side delay. This thesis argues that, for the tested class of mixed workloads on shared commodity infrastructure, these communication roles should be separated architecturally rather than forced through a single protocol. To evaluate that claim, the thesis formalizes an asymmetric control- telemetry pattern and instantiates it in the Asymtra framework using gRPC for synchronous control and …
