This paper is devoted to the explanation of selected bureaus’ behavior patterns in the soviet type of totalitarian dictatorships with the command economic model. It is a proven fact that the plan figures in the soviet economy were fabricated as a consequence of intrigues and secret negotiations between different interested parties. Generally, bureaus, as rational agents that minimize risk and maximize slack, should have been interested in reducing the plan figures, nevertheless, they strived to increase them. As examples, mass repression under dictatorships and overexpenditure of an administrative leverage at elections in non-democratic and quasi-democratic countries can be observed. In the article we develop a simple model of coordination between principal (dictator) and his agents (bureaus), which explain the mentioned paradoxical situation.
The article is dedicated to the elements of Byzantine influence in the Caucasian architectural monuments of 9th–10th c. Its greatest extent shows from the end of 9th c. Abkhazia and Alania, where a local version of the provincial (Pontic) Byzantine architecture was created. In Kakheti several groups of Byzantine master-builders participated in the 10th c. in construction of churches in Vachnadziani, Sanagire, Bodbe etc., and also brought here the tradition of brick architecture. In Klarjeti and Tao the Byzantine builders, who used opus mixtum technique, were involved in different way in the 950-960’s in the construction of the churches in Opiza, Doliskhana, Dört-Kilise, Sinkoti and Ezbeki. Finally, in Armenia Byzantine influence was manifested from the middle of 10th c. in the brick architecture of Vaspurakan.
