Effects Of Wetting And Drying On Nutrient Mobilization In Aquatic Systems, Karessa Grace De La Paz
Effects Of Wetting And Drying On Nutrient Mobilization In Aquatic Systems, Karessa Grace De La Paz
Graduate Theses and Dissertations
Wetting and drying cycles are a fundamental, but underexplored, control on nutrient mobilization and transport in aquatic ecosystems. Such intermittency impacts approximately 60% of the world's streams and rivers, and the extent is expected to increase with future climate change. Additionally, aging reservoir infrastructure is driving restoration efforts, like large-scale drawdowns, that can expose benthic sediments to extended dry periods before refilling. Despite the prevalence of wet-dry cycles, how they influence nutrient transport and mobilization across different aquatic ecosystems remains poorly understood. To address this gap, this thesis presents two complementary studies exploring nutrient dynamics in Arkansas aquatic ecosystems that …

Participants were exposed to …
Religion, Crime, And The Mediating Effects Of Social Control And Self-Control, Parker Bowman
Religion, Crime, And The Mediating Effects Of Social Control And Self-Control, Parker Bowman
Graduate Theses and Dissertations
Past research on the relationship between religion and crime has found the two variables have a significant negative correlation. Currently, there are two main mechanisms used to explain this relationship: social control and self-control. Social control theorists argue that participation in religious organizations decreases criminal behaviors by increasing social bonds. Self-control theorists argue that religious norms and values decrease criminal behavior by increasing an individual's self-control. While both mechanisms have been well supported by research, there remains the question of which is the stronger mediator of the religion-crime relationship. This study seeks to answer this question by comparing the effects …

Privacy Protection In Cloud-Based Biometric Systems, Yatish Reddy Dubasi
Privacy Protection In Cloud-Based Biometric Systems, Yatish Reddy Dubasi
Graduate Theses and Dissertations
The widespread adoption of server-based biometric authentication systems, often hosted in the cloud, has introduced significant privacy risks. While these systems offer convenience, they require storing sensitive biometric templates on remote servers, creating a high-value target for adversaries. Unlike passwords, compromised biometric data is immutable and cannot be reissued, leading to an irreversible loss of privacy. This threat is exacerbated by template inversion attacks, which can reconstruct a user's original biometric trait (e.g., a face image) from its stored feature vector. This dissertation addresses these critical privacy challenges by designing, implementing, and evaluating a suite of novel frameworks for privacy-preserving …
Ecological Elemental Homeostasis And Stoichiometric Shifts: Biotic Responses To Ionic And Viral Stress, Samuel Anthony Tooru Dias
Ecological Elemental Homeostasis And Stoichiometric Shifts: Biotic Responses To Ionic And Viral Stress, Samuel Anthony Tooru Dias
Graduate Theses and Dissertations
Anthropogenic activities are reshaping the elemental composition of freshwater ecosystems, often creating stoichiometric imbalances that influence the growth, physiology and interactions of aquatic organisms. Ecological stoichiometric theory (EST) provides a framework for examining these changes by linking organismal elemental regulation to broader ecosystem processes. While traditionally focused on elements, such as carbon (C), nitrogen (N), and phosphorus (P), emerging stressors highlight the need to expand this framework to be more elementally inclusive for the examination of novel interactions. My dissertation integrates abiotic (salinization) and biotic stressors (viral infection) into an EST framework to evaluate how these factors alter elemental regulation …
