Design, Synthesis, And Polymerization Of Novel Heterocyclic Monomers As Precursors For Functional Polyester, Poly(Ester Amide)S And Polyamides, Eylem Tarkin-Tas

Dissertations

The research presented in this dissertation involves the synthesis and polymerization of heterocyclic monomers which pave the way to biodegradable polyester nanocomposites, functional polyesters or poly(ester amide)s, functional polyamides and supramolecular polymers. The key monomers are ε-caprolactone, γ-acetamido-ε- caprolactone, γ-ethylene ketal-ε-caprolactam and α-amino-ε-caprolactam.

Poly(ε-caprolactone) organo-modified montmorillonite nanocomposites were prepared by in-situ polymerization using dibutyltin dimethoxide as initiator/catalyst. The montmorillonite was first modified with 1-decyl-2-methyl-3-(11-hydroxyundecyl)- imidazolium cation. The hydroxyl functionality was used for not only initiating polymer chains from the surface of the clay platelets but also for grafting polymer chains to the surface by acting as a reversible chain transfer …

If And To What Extent Spirituality Impacts The Leadership Practices Of Four African American Superintendents, Christopher James Williams Sr.

Dissertations

Public school superintendents have one of the most challenging, demanding, and visible positions in American society. They provide educational leadership in approximately 15,499 school districts across the United States. Their visibility is marked by the fact that the majority of leadership positions are held by non-minority individuals (American Association of School Administrators, 1992). The underrepresentation of minorities in public school leadership positions on a national level has been thoroughly documented over the years, and the limited representation of African Americans in top positions of public school administration is glaring (AASA, 1992, 1983; Jones & Montenegro, 1988, 1985; Montenegro, 1993). The …

Reading With A Critical Global Perspective: A Study Of Children's & Adolescent's Literature On South Asia, 1989-2009., Manika Subi Lakshmanan

Dissertations

This study examines how children’s and adolescent’s literature promotes global awareness, cross-cultural understanding and cosmopolitanism. It proposes an alternative critical global perspective in the teaching of complex narratives dealing with socio-economic and political transformations in the developing world, with specific reference to South Asian societies. Reframing how transcultural literature is read, a critical global perspective combines global perspectives distilled from theories of development, human rights and international relations, Michel Foucault’s notion of discourse and critical analysis, and textual and visual analysis (Stephens, 1992; Kress and van Leeuwen, 1996). This multidimensional approach contributed 20 questions that explored the gap between cultural …

A Qualitative Study Of A Native American Mascot At "Public University", Michelle Lyn Brune

Dissertations

At the time this study began, there were approximately 60 senior colleges and universities using Native American mascots or nicknames to represent their athletic teams (Fournier, 2003). Many Native Americans, coalitions, organizations, and researchers (Connolly, 2000; Davis, 2002; King & Springwood, 2000; NCAA, 2001) believe that these mascots are racist stereotypes of Native Americans and recommend that they be banned. In contrast, other people believe that Native American mascots signify honor and tradition. Differing meanings or opinions create an obvious conflict and each viewpoint includes a set of arguments to justify their beliefs. For example, many universities claim their alumni …
