The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

74 CREATIVITY AND INNOVATION MANAGEMENT Case Study: Jack Welch’s Creative Revolutionary Transformation of General Electric and the Thermidorean Reaction (1981–2004) Pier A. Abetti This case study draws a parallel between the French Revolution and the GE ‘revolution’‚ according to three waves of transformation. We discuss the ‘hard’ effects on GE employees (strategy‚ structure‚ employment‚ rewards) and the ‘soft’ effects (culture‚ work climate‚ indoctrination). In parallel with the French

1. How does IKEA generate customer loyalty? a) Low price As the case said “IKEA achieved this level of success by offering a unique value proposition to consumers: leading-edge Scandinavian design at extremely low prices” and IKEA’s vision is “to create a better everyday life for the many people.” “People have very thin wallets. We should take care of their interests.” While IKEA overarching strategy is focused on offering customers everyday low prices‚ the loyalty program is one of the ways

One proposed reason for this harsh reality of high poverty rates is globalization - the growing integration of economies and societies around the world. The claim that globalization generates poverty has been the focus of many debates for the last twenty years‚ including the debate between Carlos Caretto‚ Gillian Crowl‚ Steve Grossman‚ and Annie Wong on February

generating dramatic comedy in Waiting for Godot? The absurdity of Waiting for Godot by Samuel Beckett generates comedy as the ‘theatre of the absurd’ is described as a form of drama that highlights the absurdity of human existence by showcasing the disjointed‚ repetitious‚ and meaningless dialogue‚ the purposeless and confusing situations‚ and the plot that lacks realistic or logical development.1 This theme is perhaps the most prominent theme in the play. In his article‚ ‘Vaudeville‚ Pantomime and Tragedy

Activity 4: Generation of Action Potentials Name: Instructor: Date: PREDICTIONS 1. Exceeding the threshold depolarization at the trigger zone DECREASES the likelihood of generation of action potential. 2. Action potential amplitude: DOES NOT CHANGE with distance 3. Increasing frequency of stimulation to the trigger zone: DOES NOT increase the production of action potentials.
