of participation in the group affairs to the people who do not belong to it, as they apprehend that it (including the information coming from them) will break the unity of the group.
Rational-universal method of decision-making implies an unambiguous definition of the substance of a problem and ways of its solution. Its basic advantage consists in that when realized it allows complete and radical solving the problem or a preset task. Branch method implies taking partial decisions directed towards the improvement of situation, rather than complete solution of a problem (for example, under conditions of insufficient clarity of a problem, ways and means of its solution, in the absence of full information on the situation, given the lack of possibility to foresee all the consequences of the radical solution, under the pressure of the influential forces inducing to compromises, the possibility of rise of sharp conflicts with unclear outcome, etc.). Mixed (mixed-scanning) method implies rational analysis of the problem and singling out of its main, key component which is attached a paramount importance and to which rational-universal method is applied. Other elements of the problem are solved gradually by making acceptable partial decisions that allows to focus efforts and resources on the key areas and at the same time have complete control over other elements of the situation, thus providing its stability. p> Selection/choice mechanism. The optimal selection mechanism may be considered the consensus-based system in which each participant of decision-making votes not for one, but for all options (preferably more than two) and ranges the list of options in the order of his/her own preferences. Thus, if four possible options are offered the participant of decision-making (the voter) defines a place of each of them. The first place is given 4 points, the second, third and forth are given 3, 2 and 1 points, respectively. After voting the points given too each option (the candidacy/nominee) are summed up and selected option is determined based on the quantity thereof. If sums of scores for any options are found equal, repeated voting is held only for these options. p> Networks. Network is determined as spatial, constantly changing dynamical system consisting of elements identical in terms of some parameters: actors (figures), activity and resources (key for this type of a network), connected among themselves by communication flows. The network structure is the description of boundaries of interrelations between the elements and position of elements in the network. The actors, activity and resources are connected with each other across the entire structure of network. The actors develop and maintain relations with each other. Various kinds of activity are also connected among themselves by relations, which may be called a network. Resources are consolidated among themselves by the same structure of network, and moreover, all the thr...
