An Investigation Into The Mechanisms, Barriers, Degree And Sphere Of Risk Influence In Corporate Security, Nicola Lockhart

Theses: Doctorates and Masters

This study investigates the sphere of corporate security risk influence within organisations, addressing the conceptual and practical ambiguity surrounding the activity’s capacity to shape organisational decisions, behaviours, and risk priorities. While corporate security’s protective role is widely recognised, its broader organisational risk influence remains under-theorised. The study defines the sphere of risk influence as the range of organisational stakeholders and environments with which the corporate security activity interacts, and within which it may engage, persuade, and mobilise action. This sphere is analytically constituted through the intersection of three dimensions: the mechanisms through which influence is attempted, the barriers that constrain …

The present study examined the effects of functionally indicated choice-based antecedent interventions on academic and behavioral outcomes for elementary general education students exhibiting elevated levels of off-task behavior during independent seat work. A replicated hybrid single-case design was used to compare two interventions: choice of task sequence (across-activity choice) and choice of peer (within-activity choice). Brief functional behavioral assessments (FBAs) informed hypothesized behavioral function and intervention match. Dependent variables included academic engagement (on-task behavior), with off-task behavior conceptualized as its inverse, as well as academic completion and accuracy; social validity was assessed from teachers and students. Results indicated support for …

Categories, Homology And Sheaves For Hypergraphs, Robert Green

Electronic Theses & Dissertations (2024 - present)

Hypergraphs are a prominent tool for representing networks with connections among three or more entities. There is an inherent flexibility that allows hypergraphs to more naturally represent certain types of networks than graphs or simplicial complexes can on their own. This flexibility, however, comes at a cost, as there is a zoo of various categories and homology theories that are applicable to hypergraphs. The first chapter of this dissertation explores various categorical perspectives on hypergraphs, focusing on what the natural notion of morphism between hypergraphs should be. It also contains an exploration of the functoriality of vertex-edge duality in these …

Photo And Spatial Control Of Rna Structures And Functions: Exploring Positional Effects And Photo-Responsiveness Of Azobenzene Modified Nucleotides, Jinxi Du

Electronic Theses & Dissertations (2024 - present)

RNA molecules perform many important biological functions by forming complex three-dimensional structures stabilized by base pairing, tertiary interactions, and metal ion coordination. Because RNA function depends strongly on its structure, methods that allow reversible control of RNA conformation and activity are important for understanding RNA behavior and for potential therapeutic applications. However, achieving reversible and site-specific control of RNA structure, especially at the single-nucleotide level, remains challenging. In this dissertation, I developed and applied azobenzene-modified nucleotides as a chemical tool to enable optical and spatial control of RNA structure and function.

The first part of this dissertation focuses on establishing …

When Civilians Involve Themselves In Crime Control: Do Perceived Police Legitimacy And Trust In The Police Predict Support For Vigilantism And Citizen’S Arrests?, Charlotte T. Parque

Electronic Theses & Dissertations (2024 - present)

Recent cases in which civilians involved themselves in the crime control process have garnered divided reactions, with some people supporting and others disapproving the civilians’ actions. Although existing research shows that perceptions of the police predict support of civilians involved in crime control, exact directions of the effects conflict. I address these conflicting findings by examining how people conceptualize police legitimacy and trust in the police, whether those conceptualizations align with scholarly definitions of legitimacy and trust, and explore if the two constructs differentially predict support of vigilantism. Additionally, I explore whether people approve of two types of civilian crime …

Investigation Of Fine-Grain Cu And Cu Alloys For Low-Temperature Hybrid Bonding Applications, Sarabjot Singh

Electronic Theses & Dissertations (2024 - present)

Hybrid bonding has emerged as a key enabler for next-generation three-dimensional (3D) integration, offering fine-pitch interconnects and improved electrical performance. However, conventional Cu–Cu hybrid bonding typically requires elevated temperatures to achieve sufficient diffusion and interface quality, posing challenges for temperature-sensitive device integration and process compatibility. This work investigates materials engineering approaches to enable low-temperature Cu–Cu bonding through both microstructure design and alloying strategies.

This work begins by examining grain refinement in Cu as a pathway to enhance diffusion through increased grain boundary density, providing efficient atomic transport without introducing additional elements. Three Cu-based systems Cu–Co, Cu–Ag, and Cu–Al were systematically …
