Energy in a Triangular Pulse. A triangular wave pulse on a taut string travels in the positive ?x?-direction with speed ?. The tension in the string is ?F?, and the linear mass density of the string is ???. At ?t? = 0, the shape of the pulse is given by (a) Draw the pulse at ?t = 0. (b) Determine the wave function ?y?(?x?, ?t?) at all times ?t?. (c) Find the instantaneous power in the wave. Show that the power is zero except for ??L < (?x ??t?) < ?L and that is this interval the power is constant. Find the value of this constant power.
Week 7 Notes Comm 401 Mary Note taker Chapter 7: Power and Resistance at Work Symbols (such as a corner office in a workplace) hint at power statuses. Power is to organizations as oxygen is to breathing -Clegg, Courpasson, and Phillips (2003, p.3) POWER- "a pervasive feature of organizational life...“ It is not able to be possessed, but rather "exercised through a dynamic process in which relations of interdependence exist between actors in organizational settings" (P. 160). Perspectives on Power and Organizations- p.158-163 There are different theories of power • All social relations have a system of power, whether visible or invisible. o e.g. students and professors Power gets a little fuzzier when there is a level playing field for everyone involved. 1. Theory of Power as a Social Influence • Social psychologists John French and Bertram Raven came up with 5 bases for social influence: i. Positional Power (aka legitimate power) ii. Referent Power (rooted in person in control's charisma) iii. Expert Power (rooted in who has knowledge/expertise) iv. Reward Power (ability to give people positive feelings about themselves or organization- promotions, pay raises, better parking spot, etc.) v. Coercive Power (punishment system is used)
