Procrastination : Development Of A Scale, Steven E. Newell

Masters Theses

Procrastination is a pervasive and recalcitrant problem. It is especially endemic to academic settings. This research reviews the major findings in the research literature and develops a procrastination scale that addresses some of the limitations found in previous self-report measures of procrastination.

Results support the Procrastination Scale's reliability and validity as a measure of procrastination. Also, the results replicate and extend information about the personality characteristics which appear to accompany and possibly facilitate the development of procrastination. These include social anxiety, public self-consciousness, passive-aggressiveness, and (inversely) self-esteem.

Neutrino-Nucleon Interactions In The Tohoku 1.4-Meter Bubble Chamber, Michael Dwayne Pugh

Masters Theses

This dissertation describes a study of the weak interactions of neutrinos with freon in the Tohoku 1.4-Meter Bubble Chamber, with emphasis on those interactions that produce slow protons emerging in the final state. The bubble chamber was exposed in 1985 and 1987 to the Fermilab wide-band neutrino beam generated by 800 GeV protons at the Tevatron. Holographic photography was used in order to improve the sensitivity to protons with very short ranges. A total of 364,000 frames were taken using normal optics.
