Effective inter-sector cooperation requires appropriate communication channels which all partners can use. The paper reviews currently available communication channels, identifies preferred communication methods of organisations in various sectors of the economy, and proposes a computational model to streamline inter-sector cooperation. The author devotes particular attention to the ways in which modern communication channels and management algorithms for information flow could be used to improve the transfer of information across sectors.

The study aimed at evaluating of the role of communication channels in recognition of facial and vocal expression of emotions. It was based on ABAKUS experiment, which is the modification of Davitz's search paradigm (1964). The results confirmed the assumption of additivity of visual an acoustic channels. The subjects (N=90) recognized emotions quicker and with greater accuracy when they were presented in the visuo-acoustic than in the acoustic channel. Moreover the dynamic form of presentation (film) resulted in the higher rates of recognition than the static one (photographs). Recognizing emotions from vocal expression turned out to be the most difficult. The most common errors made by the subjects were confusion of fear and sadness in acoustic channel and fear and anger in visual channel.

Mobile marketing has some undeniable advantages over other communication channels, such as interactivity, location based services and impulsiveness (spontaneity). However, a cell phone and other mobile devices are treated by users as personal devices in relation to which they are reluctant to see the interference from outside. The challenge for the industry is therefore a good understanding of the restrictions associated with this form of communication. Factors specific to m-marketing include profile of the recipient, the context and motivations of the user 'in motion'.
