Even emotionally healthy families suffer from the subsequent pain, trauma, isolation, and stigma. The project proposes a solution to broken or inhibited family communication: the engagement of all family members in healing …

Limited By Design: Expanding The Boundaries Of Schooling Policies From Demanded Passivity To Transformative Practice, Natalia T. Carvalho-Pinto

Masters Theses

Schooling is often imagined as the great equalizer and the primary venue towards personal and collective liberation. However, hegemonic ideals and practices have limited the ability for educators to craft and utilize policy in a way that best benefits their students. In this thesis, I utilize the state of Michigan’s Common Core curriculum to examine the limits beyond policy and practice. Specifically, I argue that the demands for student passivity and institutional measurable as signs of success, prohibit student growth. Throughout the document, I describe hope in the ability to instill a variety of transformative educational theories and practices that …

It has been said that music is a universal language: but all cultures use it differently and therefore it is not a universal language but a universal phenomenon. What about the individual who cannot hear the music or …

Finding Identity Through Irish Music In The Appalachian Mountains, Marina Delores Rayl

Masters Theses

The Appalachian Mountains are filled with remnants of Scot-Irish heritage. The music found in this region includes bluegrass, Old-time, and country music, all created from the blending of Scottish and Irish traditional music with other ethnic sounds. Despite these music variations, traditional Irish music has remained consistent in its original form in the mountain region. This concept is supported by the popularity of two key events occurring in both the northern and southern sections of the Appalachians. Through fieldwork and personal interviews, the rationales of those who participated were discovered. The research brought to light three people sub-groups revealing the …

Equals: Redefining The Way Graphic Design And Narrative Film Combine To Create Visual Metaphor, Kevin Harris

Masters Theses

This paper provides a methodology for combining Graphic Design and Narrative Film together in a way that creates a type of visual metaphor that is central to the story and characters of the film. Because visual mediums of communication are so intrinsically tied to verbal means of communication, this methodology is grounded in the linguistic study of poetry and metaphor. Thus, the concept of metaphor will be analyzed thoroughly in language, poetry, fine arts, and modern arts. The ways in which metaphor is created visually through the art forms of graphic design and narrative film will be of upmost interest …
