In the world of finance, futures trading is a very important activity to understand. It can have a great impact on all our lives as it effects the future prices of essential items such as food, energy sources and raw materials. A futures contract is a contract between a buyer and seller where an asset of certain quantity and quality has a price agreed for it today with delivery and payment for the asset occurring at a specified future date. In this free online course the world of futures trading, and its importance, is explained in a clear and easy-to-understand manner. You will learn how money is made based on the demand for a certain commodity and the trade-off between wanting that commodity now, rather than waiting for it at a later date for a given price. Examples of high demand commodities are gold, silver, oil and corn. This free course will be of great interest to professionals in business, finance and economics who would like to learn more about the concept and practice of futures trading and to all learners who would like a better understanding of how the prices of essential items such as food and raw materials are set.<br />

Dominic Orr, CEO of Aruba Networks, describes his experience applying the HP way to a startup environment. Orr speaks ab

Dominic Orr, CEO from Aruba Networks, started up a small company in a market which was dominated by the likes of CISCO Networks. It was a daunting task bringing his own product to market in competition with such a huge giant of technology. In this free online course Dominic reveals what drove him to follow his passion and see it through to execution. He reviews the fundamental characteristics and support systems needed to bring a small startup business to where Aruba Networks is today. He discusses how it was necessary to bring big company culture and attitudes to his start-up business to maximise productivity from his team of employees so that the business could capitalise on its IPO and bring the company to world-class level. Brutal honesty is a phrase he uses more than once to define how key decisions were made throughout this growing process. This course will be of great interest to business professionals and entrepreneurs starting up their own business or growing an existing business and who are competing in a market dominated by large multinational companies. <br />

This MOOC is intended for anyone comfortable working with Microsoft Office 2007 or 2010 that is considering transitioning to an Office 365 or Office 2013 software package...
