Development Of Innate Immunity During In Vitro Differentiation Of Mouse Embryonic Stem Cells, William D'Angelo

Dissertations

Embryonic stem cells (ESCs) hold enormous promise for the goals of regenerative medicine and tissue engineering, and extraordinary progress has been made in defining conditions for differentiation to desired cell types. However, an often overlooked aspect of ESC biology is innate immunity, the ability of cells to detect and respond to pathogens and inflammatory cytokines. A number of recent studies by our lab and others have established that ESCs and other types of pluripotent cells from both mice and humans do not mount typical immune responses to viral or bacterial stimuli. There are also indications that various cell types differentiated …

The Good Behavior Game: Effects On And Maintenance Of Behavior In Middle-School Classrooms Using Class Dojo, Komila Dadakhodjaeva

Dissertations

Classroom management is one of the key components for successful instruction and affects both instructors and learners. Although most frequent discipline strategies in schools involve punitive actions, research suggests that using positive statements to teach and reinforce desirable behaviors is more appropriate and effective. A form of a group-oriented contingency that focuses on desirable behaviors is a positive variation of the Good Behavior Game (GBG). The GBG has been used widely in its original form, focusing on undesirable behaviors, and more research is needed on its positive version. Another strategy that can be used within classrooms is Class Dojo, a …

Evaluation Of A Positive Version Of The Good Behavior Game Utilizing Classdojo Technology In Secondary Classrooms, William Blake Ford

Dissertations

Appropriate and effective classroom management skills are critical in supporting students’ academic, social, and behavior development in schools; however, teachers often cite needing help with classroom management as their greatest need. Given this concern, school psychologists need effective and efficient strategies to offer to teachers and school staff dealing with classwide behavioral difficulties. The Good Behavior Game (GBG) is an empirically supported interdependent group contingency intervention providing explicit classroom management techniques aimed at improving student behavior. The purpose of this study was to assess the effects of a positive version of the GBG utilizing ClassDojo technology on classwide academically engaged …

Bioinspired Design Of Wetting And Anti-Wetting Surfaces Via Thiol-Ene Photopolymerization, Li Xiong

Dissertations

Surface wettability is known to have a profound influence in both academic study and industrial application of materials. Superhydrophobic surfaces, with a static contact angle higher than 150° and a contact angle hysteresis lower than 10°, have received continued attention for their broad applications, such as self-cleaning, antifogging and frosting, and drag reduction. The continuous development of materials and approaches that used to create superhydrophobic surfaces has led to further exploration of coatings with other desirable properties such as superamphiphobicity, mechanical robustness and thermal stability.

In this work, coatings with super wetting and super anti-wetting properties were designed and fabricated …
