This paper introduces Rational System Perspectives in relations to four promin ent schools of organization theory; which are Taylor’s scientific management‚ Fayol’s general principles of management‚ Weber’s theory of bureaucracy and Simon’s discussion on administrative behavior.

Two important personality theories are the biological theory and the humanistic theory. The biological theory is based on the premise that all people inherit their characteristics from their family. This theory basically contends that people do not have control over their behaviors because they are genetically pre-determined. The humanistic theory‚ on the other hand‚ is based on the premise that each person has free will to control their actions. This theory does not go along with the idea that behaviors

equal to the square root of the amount of the payoff. So‚ we get Ui(a) = √x‚ x≥0 Where x is the amount of the payoff The decision theory tells us that the act with the highest expected utility should be chosen. We denote the expected utility of act a1 (AB Ltd.) by EU(a1) and the expected utility of act a2 (XY Ltd.) by EU(a2). Thus‚ we get EU(a1) = 0.5 x √1089 + 0.5 x √0 = 16.5 EU(a2) = 0.5 x √324 + 0.5 x √196 = 16 ∴ Ajay should choose act a1 and invest in AB Ltd. since it has

THEORY OF CONSTRAINTS The Theory of Constraints (TOC) is a management philosophy where three financial measures of profit‚ return on investment (ROI) and cash flow are presented. All three of these measurements are necessary. First‚ we need an absolute measurement of profit‚ the amount by which revenues exceed expenses. Second‚ we need the relative measurement of ROI that compares the amount of money made relative to the amount invested. Finally‚ we must have enough cash coming in to meet expenses

Application of Nursing Theory Nurses have to make numerous decisions on a day to day basis. Some are simple decisions and other issues are more complex and require guidance to make decisions. Nursing theory is one way for nurses to make decisions based on problems or situations they face. As Cody (2003) states‚ “one learns to practice nursing by studying nursing theories” (pg. 226). This statement can be applied to problem solving and decision making. By using theory‚ nurses can apply concepts
