A factor-analytic reinterpretation of the Clark-Trow "educational philosophies"

Each of four principal components analyses (n = 3,944) incorporated student self-ratings (Most accurate to Least accurate) on one of the four Clark-Trow educational philosophies: Vocational, Academic, Collegiate, Nonconformist. The analyses of these 25-variable correlation matrices yielded 2 factors differentially associated with educational philosophy: Sociability versus Independence (replacing Clark-Trow's "Identification with the College") and Liberalism versus Conservatism (replacing Clark-Trow's "Involvement with Ideas"). The Vocational philosophy was associated primarily with Conservatism, the Collegiate with Sociability, and the Nonconformist with Liberalism; the Academic was moderately associated with both Independence and Liberalism.

Characterization of Biodegradable Polymer Nanocomposites Fabricated via Solid-State Processing

Biodegradable polymer/clay nanocomposites were prepared withpristine and organically modified montmorillonite in polylactic acid (PLA) and polycaprolactone (PCL) polymer matrices. Nanocomposites were fabricated using extrusion and SSSP to compare the effects of melt-state and solid-state processing on the morphology of the final nanocomposite. Characterization of various material properties was performed on prepared biodegradable polymer/clay nanocomposites to evaluate property enhancements from different clays and/or processing methods.
