The Örst is the identiÖcation of the public perception of monetary policy to establish a relationship between this perception, the behaviour of monetary authorities and some key economic variables.

  • This morning I have reviewed the outlook, the Federal Reserve’s response, and its policy options for the future should the recovery falter or inflation decline further. In sum, the pace of recovery in output and employment has slowed somewhat in recent months, in part because of slower-than-expected growth in consumer spending, as well as continued weakness in residential and nonresidential construction. Despite this recent slowing, however, it is reasonable to expect some pickup in growth in 2011 and in subsequent years.

  • The scientific world has changed. For nearly two centuries after Newton, his ideas held sway, and found widespread adoption in many other disciplines. Subsequent advances in the sciences – from Einstein’s relativity thinking to quantum physics – have since replaced the Newtonian world-view in many disciplines.

  • Change is a common feature of the IT world. It is important that effective control procedures are in place to ensure that only authorised changes are made to IT systems. Not only is there scope for the accidental or deliberate inclusion of unauthorised code (the so called Trojan horse or time bomb) but change involves a degree of risk and it is necessary to ensure, for example, that the right version of software is actually implemented.
