"And So He Plays His Part:" Theatrical Prejudice And Role-Playing In As You Like It And King Lear, Erin Rutter Nov 2005

"And So He Plays His Part:" Theatrical Prejudice And Role-Playing In As You Like It And King Lear, Erin Rutter

Graduate Theses and Dissertations

Although most critics affirm the importance of interior direction and role-playing in many of Shakespeares plays, there is a considerable disagreement concerning the result of this role playing: does it lead to positive growth or to degeneration? Moreover, this debate is often associated with the sixteenth-century controversy about the role of the theater in society. Some moralists insist that the theater can be an instrument for instilling virtue while others view the theater as sinful, debasing, and a catalyst to social breakdown. In this thesis, I will explore the antitheatrical prejudice in the early modern era and show how Shakespeare ...

Reducing Pollutants In Industrial Stormwater Runoff: Improved Water Quality Protection Using Prioritized Facility Regulation, Lindsay M. Griffen

Graduate Theses and Dissertations

Stormwater pollutants originating from industrial facilities can lead to degraded

water quality, even in residentially dominated regions of the country. The National

Pollutant Discharge Elimination System permit program regulates stormwater pollutants

generated at industrial sites using Multi-Sector General Permits (Generic permits) for

industrial facilities and a permit requirement for Municipal Separate Storm Sewer System

(MS4) operators. All industrial facilities within 11 broad categories of industry are

responsible for self-identifying the need to comply with the Generic permit, and

subsequently, implementing self-selected pollution prevention strategies. MS4 operators

are required to identify and inspect “high risk” industrial and commercial facilities that

may ...
