The economic approach towards trust gives suggestions how a causal role of trust could be established experimentally. And the biological and behavioral evidence indicating that trusting is not just a special case of risk-taking, but based on important forms of social preferences such as betrayal aversion. The results show that a high level of trust is an important determinant of the effectiveness of cooperation as well as a key component of reducing transaction costs.

Results of researches on joint influence of specific pressure of pressing and firing temperature on physico-mechanical properties of laboratory samples on the basis of atyukhtinsky clay raw materials is shown. For the purpose of increase of frost resistance of the burned samples into structure of masses entered a carbonat containing modifying additive in an amount of 5%. For a quantitative assessment of influence of the specified factors on the main indicators of the burned samples researches with application of mathematical planning of experiment and computer processing of results were conducted. Specific pressure of pressing varied within 20±5 MPa, firing temperature – 1000±50 0C. By results of experiment the regression equations are received. It is defined that at increase of value of both varied factors, frost resistance and durability of samples increase, and water absorption – decreases. It is shown that, operating even with two technology factors – the specific pressure of pressing and firing temperature – it is possible to change significantly properties of finished products, and, using the received equations, it is possible to predict future properties of products at a stage of their production.

Modern trends in the transformation of business structures and forms of inter-firm cooperation have led to the emergence of new organizational and structural solutions allowing businesses to successfully compete in the market, respond quickly to changes in the external environment and internal changes, contributing to the development potential of the business. So in the Russian economic practice, along with established corporate organizational structures and network business structures brand new specific structural forms are gaining popularity, being diversified entrepreneurial business systems, combining features of corporate and network structures, but also having specific characteristics that allow them to be identified as an independent type of structures. This paper discusses the most important parameters influencing the development of a diversified network of entrepreneurial business systems and analyses key characteristics of the data structures to identify their place in the chain of organizational structures evolution

"This review covers various methods of synthesis LaMnO3 ferroics. The general analysis of the solid-phase synthesis reactions methods and wet methods (sol-gel, sorption, co-precipitation) are carred out. The original results of LaMnO3 syntheses from various precursors by means of the in situ method are showned. The advantages and disadvantages of different methods of synthesis are determined. The analysis of synthesis LaMnO3 ferroics published data is shown:
- the structure formation of LaMnO3 in perovskite-type phases occurs at different temperatures, depending on precursors states;
- LaMnO3 perovskite phases differ in symmetry and unit cells parameters at room temperature, depending on the preparation conditions;
- the highest synthesis temperature of LaMnO3 are typical for solid phase reactions method (950-1050 ° C), the lowest - for wet synthesis methods (500-700 ° C);
 - the synthesis conditions effect the stoichiometry of LaMnO3 for oxygen content.
Our studies of structure formation processes of LaMnO3 by in situ method are allowed to define the role of precursors states at synthesis of solid phase reactions methods, adsorption, co-precipitation and sol-gel mixtures.
It is determined that in samples prepared by wet chemical methods, the formation processes of  LaMnO3 perovskite phases occur at lower temperatures than by solid phase reaction (sol-gel precursor - 500 <T <600 ° C; precursors obtained by coprecipitation and sorption methods - at 600 <T <700 ° C and 700 <T <800 ° C, respectively).
