Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi
Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi
Graduate Theses and Dissertations
Liquid crystals (LCs) constitute a subset of soft matter possessing hybrid characteristics from both liquid and crystalline phases. In this state, the center of masses remains uncorrelated similar to an isotropic phase, while the long axis of molecules aligns in parallel, resulting in molecules exhibiting orientational and positional order, either individually or concurrently. The directional alignment inherent in LCs arises from the asymmetrical shape and structure of the constituent molecules, causing a spontaneous self-assembly into ordered phases. This cooperative molecular behavior manifests distinctive optical features when subjected to cross polarizers. The remarkable sensitivity of LCs to external stimuli, including temperature, …

A Mixed Methods Exploration Of Interoceptive Awareness In Adults Who Stutter, Hazel Malcolm
A Mixed Methods Exploration Of Interoceptive Awareness In Adults Who Stutter, Hazel Malcolm
Graduate Theses and Dissertations
Stuttering is commonly described as a disorder of speech fluency characterized by primary speech behaviors that are judged by external observers to be typical of stuttering, including part-word repetitions, prolongations, and blocks (i.e., silent prolongations or postural fixations). Despite wide use in the field of speech-pathology, definitions focusing on these ‘primary’ behaviors have also been criticized as ‘surface’ or ‘perceptual’ definitions that favor the experience of a listener over that of the speaker. Recent qualitative evidence suggests that, when asked, adults who stutter (AWS) instead define stuttering as an internal feeling or awareness of being ‘stuck’ that is surrounded by …

The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
Graduate Theses and Dissertations
Behavioral plasticity, where individuals change their behaviors in response to varying environmental and social conditions, affects major evolutionary trajectories. But how individuals change these behaviors under certain social situations, and what the genetic causes and consequences of such behavioral changes are in response to social environments are yet to be fully understood. I address these questions in the context of anti-predatory behaviors (chapter 1), and mate choice (chapters 2, 3, 4) in tropical butterflies. In the context of anti-predatory behaviors, I found predator-specific behavioral changes in toxic Heliconius butterflies, suggesting variance in predation pressures and butterfly recognition of bird calls. …
