Principal Selection And The Stories Superintendents Tell., Linda L. Baker

Electronic Theses and Dissertations

In addition to licensure and certification, there are particular qualities and personal characteristics superintendents look for when hiring a principal. With fewer principal applicants and increased projected needs for principals, it was important to explore the superintendent's reasoning when hiring a principal.

A qualitative research method employing elite interviews was used to explore the criteria that superintendents employ in their process of selecting a principal. When talking about the hiring of principals, superintendents invariably began with the selection process. Teachers, community members, parents, former employers, and college professors gave input in formal or informal ways. Superintendents looked for experience both …

Synthesis And Use Of Chiral Surfactants., Xiaoye Yang

Electronic Theses and Dissertations

It has been previously shown that micelles formed from surfactants with chiral head groups serve to induce a chiral reaction medium, leading to enhanced enantioselectivities in the reaction products. This utilization of chiral surfactants will offer an economical alternative to traditional chial solvents while simultaneously reducing organic waste. We have successfully dimethlated S-leucinol in an 85% yield, and have synthesized a hydrocarbon-based surfactant with this molecule as a head group. We have also formed polymeric surfactants that have polydimethylsiloxane as the hydrophobic portion with the (S)-dimethylleucinol as a head group. Tests of the solubility of these surfactants have been conducted. …
