A summary of Diffusion of Innovations Les Robinson Fully revised and rewritten Jan 2009 Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea‚ behaviour‚ or object that is perceived as new by its audience. Diffusion of Innovations offers three valuable insights into the process of social change: - What qualities make an innovation spread successfully. - The importance of peer-peer conversations and peer networks.

BANK OF AMERICA’S MASTERNET SYSTEM: A CASE STUDY IN RISK ASSESSMENT By Jeffery G. Szilagyi Abstract In 1982‚ Bank of America initiated the development of the Master Net trust accounting system. After $78 million in losses on the project‚ the bank announced in 1988 that its trust business was being given to a subsidiary because it could no longer handle the operational requirements. MasterNet quickly became known within the information system industry as a classic case of a system that had fallen

Simple diffusion The term simple diffusion refers to a process whereby a substance passes through a membrane without the aid of an intermediary such as a integral membrane protein. The force that drives the substance from one side of the membrane to the other is the force of diffusion. In order for substances to pass through a cell membrane by simple diffusion it must penetrate the hydrophobic core of the phospholipid bilayer. The types of molecules that can do this are themselves substantially

Between the years 600-1450‚ the civilizations in Europe and West Asia further developed their individual empires and displayed much growth and influence. Socially‚ both regions developed patriarchal societies‚ but had different social structures. Culturally‚ Europe and West Asia received outside influences and effectively spread their religions. Economically‚ they interacted with other regions to enhance their societies. Thus‚ the social‚ cultural and economic aspects helped give rise to interaction

absorption rate increased‚ showing that the smaller cells absorbed more sodium hydroxide than bigger cells. The smaller cells were able to absorb more sodium hydroxide as they have a bigger surface area to volume ratio causing them to act more efficiently than the bigger cells. The smallest cell had a ratio of 1:12 while the biggest cell had a ratio of 1:2‚ leaving a gap of 5:12 causing the bigger cell to act less efficient in absorbing the solution in a period of 10 minutes. Also‚ as the size of the
