A Music Teacher’S Use Of Informances With Primary Level Classes And Study Of Family Attitudes For Music Education: An Action Research Study, Joseph Cooke Emerson

Graduate Theses/Dissertations

Concerts are often the summative project for the elementary music room. However, the emphasis on concerts creates challenges for music instruction. The preparation for a traditional concert often takes away from instructional time, which is already limited for music instruction. Second, the use of concerts conceals many aspects of the instructional process from students’ families. This results in a limited view and understanding of their child’s formal musical education. By designing opportunities for parents and other stakeholders to see students beyond a traditional concert, I thought that I could help to deepen families understanding of music education in my elementary …

Implementing The Circular Economy Concept In Construction Supply Chain Management Of Modular Steel Projects, Thet Htar San

Chulalongkorn University Theses and Dissertations (Chula ETD)

The circular economy is a modern economic model where the value of products, materials, and resources is maintained in the economy as long as possible, whereas the generation of waste is minimized. The current linear take-make-dispose model prevalent in construction supply chain management is increasingly unsustainable, marked by significant resource wastage and environmental impacts. The conventional linear supply chain models in modular steel construction contribute to unsustainable resource utilization and environmental impacts. This research explores the transition from linear to circular supply chain models. We identify key actors, potential barriers, and opportunities for implementing circular economy practices in modular steel …

The Craft Of Integrating And Layering Leadership Theories And Models For Application, Benjamin Correia-Harker

College of Education Faculty Research and Publications

To develop transformative experiences, educators must meaningfully ground leadership development interventions in theories and models that reflect how leadership is conceptualized and operationalized within a community and/or institution. Since no single framework perfectly captures the socially constructed and multifaceted nature of leadership, educators must often pull from and weave together multiple theories and models when creating leadership development programs. This article explores consideration for leadership theory application through contextual and audience alignment, as well as considerations for integration of theory that address underlying theoretical assumptions, framework gaps, and developmental readiness. Reflection prompts are provided for each consideration so educators can …

The Importance Of The Pressure Anisotropy Induced By Strong Magnetic Fields On Neutron Star Physics, Efrain J. Ferrer, Aric Hackebill

Physics & Astronomy Faculty Publications

In this paper we discuss in some detail how the pressures determined from semi-classical statistical averaging of the energy momentum tensor in the presence of a uniform background magnetic field are anisotropic with different pressures arising along and perpendicular to the magnetic field direction. Hence, we analyze how this result can affect two important characteristics of dense magnetized systems: (i) The hadron-quark phase transition in the presence of a magnetic field, (ii) The behavior of the speed of sound in dense magnetized systems. Taking into account that large magnetic fields are expected to be present in the interior of neutron …

Mergers In The Us Gambling And Horse Racing Industries: What It Means For Local Economic Development And Taxation, Thomas E. Lambert

Faculty and Staff Scholarship

Even before the Covid-19 pandemic, most sectors of the various gambling industries in the United States were showing signs of stagnation. Over the last few years, these industries have seen mergers between horse racing tracks, between horse racing tracks and casinos to form “racinos”, and between casino companies. Many gambling facilities and racetracks have closed and have been sold to developers to be used for other purposes. An industry “shakeout” is occurring, and there appears to be a trend toward greater industry concentration as consumers are showing less and less interest in gambling in general. This has been partially fueled …

Integrating Robotics Into Wildlife Conservation: Testing Improvements To Predator Deterrents Through Movement, Stewart W. Breck, Jeffrey T. Schultz, David Prause, Cameron Krebs, Anthony J. Giordano, Byron Boots

United States Department of Agriculture Wildlife Services: Staff Publications

Background Agricultural and pastoral landscapes can provide important habitat for wildlife conservation, but sharing these landscapes with wildlife can create conflict that is costly and requires managing. Livestock predation is a good example of the challenges involving coexistence with wildlife across shared landscapes. Integrating new technology into agricultural practices could help minimize human-wildlife conflict. In this study, we used concepts from the fields of robotics (i.e., automated movement and adaptiveness) and agricultural practices (i.e., managing livestock risk to predation) to explore how integration of these concepts could aid the development of more effective predator deterrents.

Methods …
