A Review Of Cost Performance Index Stability, Scott R. Heise

Theses and Dissertations

This study examines approaches currently used to determine when Cost Performance Index (CPI) stability occurs. The CPI indicates the cost performance efficiency of the work the contractor has accomplished to date; however it has value as a predictor of future contractor cost performance given that the CPI can be declared stable. Knowing that the CPI is stable allows government personnel to project the final cost of the contract and, if a cost overrun is projected, to determine the likelihood that the contractor can recover. The range method was used to test for stability of cumulative and non-cumulative (three month, six …

The Drama Of Alienation: An Interpersonal Examination Of Edward Albee's The Zoo Story And Sam Shepard's Buried Child, Lisa Arnold

Theses and Dissertations

This study examined alienation from an interpersonal communication perspective in order to find a connection between aspects of alienation and interpersonal communication.

Alienation occurs at two levels according to scholars in sociology and psychology. At the social level, one's culture influences behavior in interpersonal relations. At the psychological level, one's perception of self worth influences interpersonal relations. This study used Srole's five aspects of alienation (isolation, estrangement, powerlessness, unpredictability, and meaninglessness) to analyze interpersonal relationships between those alienated on both levels.

Two plays were chosen to exemplify how alienated people need close interpersonal communication. The Zoo Story, by Edward Albee …

An Analysis Of The Media Coverage Of The Internment Of The American Japanese During The Second World War, Vincent Fernando Arraya

Theses and Dissertations

In World War II, many Americans felt fortunate and proud to live in a democratic society based on the constitutionally guaranteed rights of all individuals. At the same time, the U.S. government was completely disregarding the civil rights of 110,000 American residents, including 70,000 U.S. citizens. They were forced to evacuate their homes and were placed in internment camps surrounded by armed guards and barbed wire. The only criterion for the actions against them was their Japanese ancestry and the military necessity was the reason given for the actions, but marital law was never declared.
