Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells in an organism & metabolic process in cells leads to the production of ATP by the breakdown of organic substances. Cellular respiration occurs

1. Introduction With the rapid development of new communications technology and network technology‚ some industries such as information industry show significant network externality characteristics. Network externality has been defined as "a change in the benefit‚ or surplus‚ that an agent derives from a good when the number of other agent consuming the same kind of good changes" (Liebowitz & Margolis‚ 1996). In other words‚ the product will be more valuable if more people use it. For example

Problems with Formal Networks Formal networks are defined‚ setup and maintained by the organization. They are put into place to make sure information‚ resources‚ problems and punishments are used efficiently and not abused. When these networks are used properly everything will flow up and down the chain of command smoothly. This chain of command comes from the basic principle of a formal network; assigning titles to employees and to give them a certain amount of responsibility to go along with
