Effects Of Multi-Day Music Enrichment On Salivary Cortisol And Cage Behavior In Shelter Dogs, Stacy D. Engerbretson

Dissertations

Rehoming shelters provide their animals with environmental enrichment with the expectation that modifying the physical space will improve kennel-related stress and subsequently abate undesirable behaviors. Although enrichment has shown moderate success at improving in-kennel behavior, increased use of physiological measurements of stress, such as cortisol, has garnered doubt as to which canine behaviors are truly elicited by a biological state of distress. Consequently, it is unknown if past examples of successful kennel enrichment decreased biological stress in addition to affecting behavior. This study explored music’s effect on salivary cortisol and music’s potential as a long-term, kennel enrichment strategy. Shelter dogs …

Virtual Smarts - Optimizing The Coalescing Of People For Collective Action Within Urban Communities, Stephen Thomas Ricken

Dissertations

Despite the importance of individuals coming together for social group-activities (e.g., pick-up volleyball), the process by which such groups coalesce is poorly understood, and as a consequence is poorly supported by technology. This is despite the emergence of Event-Based Social Network (EBSN) technologies that are specifically designed to assist group coalescing for social activities. Existing theories focus on group development in terms of norms and types, rather than the processes involved in initial group coalescence. This dissertation addresses this gap in the literature through four studies focusing on understanding the coalescing process for interest-based group activities within urban environments and …

A Biodegradable Piezoelectric Composite Scaffold Containing Zinc Oxide For Cartilage Repair Applications, Ateka Mohd Arabi Khader

Dissertations

Osteoarthritis (OA) affects 27 million adults in the United States. OA causes degeneration of articular cartilage and subchondral bone. Articular cartilage has limited ability to regenerate and repair. Bone and cartilage tissues have known piezoelectric properties, which means they can generate electrical activity in response to mechanical deformation. Using a biomimetic approach, zinc oxide (ZnO), which has known piezoelectric properties, is fabricated into a flexible three-dimensional fibrous scaffold by embedding ZnO nanoparticles into slow degrading polycaprolactone (PCL). Zinc ions can be released from the fibrous scaffold over time, which also may be beneficial for cell function since zinc has well-known …

Micronized Dry Drug Powder-Loaded Polymer Films For Delivery Of Poorly Water Soluble Drugs, Lu Zhang

Dissertations
