Evaluating C-Band Scatterometer Images For Estimating Deforestation In The Amazon Rainforest, Alex Mcbride Jun 2026

Evaluating C-Band Scatterometer Images For Estimating Deforestation In The Amazon Rainforest, Alex Mcbride

Theses and Dissertations

Satellite-based active microwave sensors have been successfully employed for a wide range of vegetation and soil studies. Spaceborne microwave instruments have proven particularly useful for wide-scale monitoring of the vegetation, especially under conditions that limit the effectiveness of high-resolution optical sensors. Satellite scatterometry can be used to detect and model deforestation in the Amazon rainforest by correlating changes in the C-band backscatter data to observed changes in vegetation coverage. The exploratory methodology developed in this paper applies the longest continuous microwave satellite record to the problem of deforestation. The backscatter measurements taken by the ERS and ASCAT missions provide more …


Lack Of Effects Of Autistic Traits On Adjunct Control Processing, Alyssa Crezee Jun 2026

Lack Of Effects Of Autistic Traits On Adjunct Control Processing, Alyssa Crezee

Theses and Dissertations

Autism has effects on social, communication, and information processing factors (American Psychological Association, 2022; Happé & Frith, 2006). Sentence processing is a type of information processing that synthesizes both discourse and local information (e.g., syntactic and morphological). This thesis explores potential effects of autistic traits on sentence processing in the context of adjunct control structures. In a two-part study, adult English L1 participants (n=118) were administered a self-paced-reading (SPR) task with comprehension and acceptability questions for task 1. Task 2 consisted of an online survey containing three standardized autism questionnaires: the Autism Quotient (AQ; Baron-Cohen et al, 2001), the Broad …

Context-Sensitive Control-Flow Analysis For Non-Standard Language Semantics, Tim Whiting Jun 2026

Context-Sensitive Control-Flow Analysis For Non-Standard Language Semantics, Tim Whiting

Theses and Dissertations

Control-Flow Analysis (CFA) is a static technique for understanding the execution of higher-order programs without running the code. CFA aids in identifying bugs, assisting program comprehension, and exposing optimization opportunities. Constructing a CFA typically begins with an idealized evaluator--such as an abstract machine or interpreter--and proceeds by approximating components of evaluation to ensure that: (a) the analysis is sound (representing all possible behaviors), and (b) the analysis is guaranteed to terminate (finitely representable). These constraints necessitate a loss of precision, providing an approximation of the values that flow to program locations rather than exact execution traces. This imprecision causes the …

Testing The Moderating Effect Of Self-Compassion On The Relationship Between Perfectionism-Related Discrepancy And Perceived Social Support From Family, Marinne Hammond

Theses and Dissertations

Perfectionism involves an insistence on outstanding performance on tasks to an extreme level. More specifically, perfectionism-related discrepancy is when one subjectively sees a gap between their performance and their expectations for how they should perform. Perfectionism may be linked to mental health issues, such as anxiety, depression, eating disorders, and social disconnection. The perfectionism social disconnection model asserts that perfectionism can also lead to social withdrawal. Self-compassion involves the acceptance of imperfection; it has been associated with higher perceived social support and has also been shown to attenuate the relationship between perfectionism and psychological distress. This study aimed to further …

Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi Jun 2026

Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi

Theses and Dissertations

This thesis examines Chimamanda Ngozi Adichie's Purple Hibiscus through an ecofeminist and postcolonial ecocritical lens, developing the concept of "wounded domestic ecology" to analyze how gendered violence operates within domestic space. Drawing on trauma studies, particularly J. R. Kurtz and Rob Nixon's concept of slow violence, it argues that harm in the novel is accumulative, produced through repetition, surveillance, ritual, and spatial regulation. Eugene's household functions as an environment that disciplines bodies, governs language, and embeds fear into everyday life. In contrast, Aunt Ifeoma's home in Nsukka offers a counter-ecology structured by sound, shared labor, and dialogic authority, interrupting the …

Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung Jun 2026

Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung

Theses and Dissertations

Social media has fundamentally transformed how narratives are produced, contested, and disseminated, enabling competing interpretations of the same event to spread rapidly across networked populations. Understanding how narratives gain traction over others in these environments is critical for addressing misinformation, supporting informed public discourse, and designing effective counter-messaging strategies. Yet existing research largely treats narrative propagation as a single-process phenomenon and focuses predominantly on textual data, overlooking both the competitive dynamics between opposing narratives and the growing role of visual symbolic communication in shaping how narratives are received. This dissertation addresses these gaps through a multi-platform, multimodal framework applied to …
