Diffusion is the movement of particles from higher to lower concentration. Find out more in this Bitesize science video for KS3.History of diffusion in physics. In the scope of time, diffusion in solids was used long before the theory of diffusion was created. For example, Pliny the Elder had previously described the cementation process, which produces steel from the element iron (Fe) through carbon diffusion. Another example is well known for many centuries, the diffusion of colors of stained glass or earthenware and.History of Diffusion. Authors; Authors and affiliations; R. E. Cunningham; R. J. J. Williams; Chapter. 361 Downloads; Abstract. It is unusual for a book dealing with the present state of knowledge in a field of physical science to give a detailed historical analysis of the subject. But anyone undertaking a detailed study of diffusion in gases will find that some discoveries which are assumed.
This thesis consists of three submitted papers and one working paper. It begins with the study of asymptotic solutions for the first passage time densities of various diffusion processes, and the thesis ends up with an application of such findings in the area of systematic trading. In between, financial bubbles and the regulatory risk management for the banking industry are studied additionally.

This paper tried to reveal the diffusion features of the imported-type management innovation in Chinese context with TQM as the research case. The study found that in different period after 1978, the initiator, rationality and diffusion life cycle of management innovation showed great differences. This indicates that to study management innovation in different contexts is significant because.
In this paper we use the entire adoption history for SWIFT (the Societyfor Worldwide Interbank Financial Telecommunication - standards provider and messagingcarrier) matched to bank-level panel data for the US, Canada and 27 European countries. Ourdataset covers almost 7,000 banks (including 1,689 SWIFT adopters) between 1998 and2005. We find that adoption appears to have large effects on.
Diffusion of Innovation is a theoretical model that seeks to explain how new ideas and technologies become cultural norms. The theory was created by Everett Rogers as a five-step process.

While history always seems relevant, the way in which it is understood and plays out clearly varies across types. In conclusion, we suggest that recent developments in sociological studies of diffusion call, beyond history, to genealogical or archaeological research strategies.
Since 1943, more than 4000 research publications have appeared and diffusion research became a widely practiced variety of scholarly study in sociology and other social sciences. This paper describes some of the history of rural sociological research on the diffusion of agricultural innovations with the goal of understanding how the research tradition emerged and to determine how it influenced.
This past experience is reviewed in the present paper. 2. INTRODUCTION. Since 1932, when the influenza virus was first isolated in the laboratory, the history of this infection can be recorded and confirmed by laboratory diagnosis. In the two centuries before this time, infections can be identified by the known signs and symptoms of disease and the explosive nature of outbreaks. Thus.
Diffusion of innovation theory tries to make clear how, why and the rate at which news or fresh idea spread through many channels to people. The diffusion of innovation helped the citizens of America in New York and Washington to understand the effects of terrorist attacks in the making and received the information efficiently.
