Large variation in the backward angles analyzing power of the $\vec p$D $\rightarrow t\pi^+$ reaction around 1 GeV

The information universe from a company point of view has changed in the last fifteen years. In fact, companies are many that are aware of the strategic information dimension. Thus, some years ago, when we talk about information management in enterprise, we talk implicitly about the documentation chain. Nowaydays, many others information approaches can be identified as intrinsically linked to information. In this paper, we try to clarify the distinctions which exist between these approaches and the actors. In addition, this study is a conclusion of some investigations realized about Economic Intelligence, particularly on the Lorraine project: DECiLOR™, in which one of our researchers contributed and we have interviewed a lot of the other actors of this project. Firsly, in this paper, we analyzed a new information discipline, infomediary discipline, we defined it, compared it to the intelligence cycle and another information discipline, the watcher. Secondly, we study the distinctions which exist between Documentation, Watch and Economic Intelligence, from the information retrieval problem (IRP) approach used. We use this last analysis to complete our first definition of the infomediary
