Mega-regional trade agreements (MRTAs) have appeared in response to the prolonged stagnation of the multilateral trading system ruled by the World Trade Organization (WTO). Although this issue has stimulated research in international integration, the specifics of MRTAs have not yet been sufficiently investigated. This article therefore assesses the multilateralization potential of regional commitments using the example of the Trans-Pacific Partnership (TPP). It includes commitments in market access liberalization made in regional trade agreements (RTAs) and in intraregional agricultural trade liberalization under the TPP. The central research problem is to identify the regional liberalization commitments that might be promoted to the level of the WTO. The authors use the methodology devised by the Organisation for Economic Co-operation and Development for assessing the potential multilateralization. RTA and MRTA commitments are grouped in two policy areas: WTO-plus (going beyond the normal provisions of the WTO) and WTO-beyond (dealing with issues going beyond the WTO). The TTP is scrutinized in the context of intraregional agricultural trade liberalization. MRTAs can raise regional commitments to the global level because of their large membership, regulatory transparency and high levels of implementation. The multilateralization of regional agreements is expected in services and investments as well as in various aspects of technical regulation. The key features of implementing RTA's WTO-plus and WTObeyond commitments in intraregional agricultural trade are discussed. Most RTAs have liberalized tariffs beyond the WTO Agreement on Agriculture (WTO-plus), but only a few have strengthened disciplines in non-tariffbarriers and implemented WTO-beyond commitments for export restrictions and export subsidies. The TPP parties are a diverse group in terms of involvement in global agricultural trade and applied tariffs on agriculture and food. The TPP provides the record in eliminating tariffs for agricultural products while keeping a number of exceptions for sensitive products and long implementation periods. Agricultural market liberalization under the TPP is achieved mostly through eliminating tariffs than by renewing non-tariffbarriers. The TPP parties share the objective of implementing WTO commitments by supporting the global agricultural trade reform on export subsidies and export bans, and agree to incorporate WTO-plus and WTO-beyond obligations.

Is devoted to the study of models of the causality of factors in socio-economic systems and processes. The author suggests a study of the causality of factors based on the theory of fuzzy binary relations using the mathematical apparatus of fuzzy implication (according to Goguen J.). As an example, the impact of corporate culture indicators on key performance indicators of the organization is given. © 2017 IEEE.

The article analyses the texts and visual images, placed on pages of the Soviet Primers mid 1940s - 1960s aimed at identifying the dynamics of the broadcast edition of the behavioral samples due to be presented to first-graders. Unchanged - normative behavioral patterns of younger students was work and collectivism. Sufficient stability are elements of a behavioral model relating to the attitude of the Soviet student. Is the idea of saving and careful handling of the things, form the skills of independent manufacture and fix things. At the same time, certain components of the normative model has been changed. The obvious transformation of the recorded field of culture and communication. The urban distribution of living standards has caused some "softening of manners" (at least at the level of reference, exemplary practices, presented to first-graders). Within the period of the 1950s and 1960s, recorded a decrease of normative level of responsibility of the first graders for economic support and food for the family, as well as reducing the standard level of independence of younger school students, with increased involvement of children in public employment practices. Certain adjustments are recorded in the regulatory relationship of the child to the benefits provided by the state. The idea of "gratitude" Homeland, broadcast in the 1940s, disappears from the pages of the Primers of the second half of the 1960s In General, texts and visual images contained in the pages of the publication, sufficiently illustrate the contradictory social trends that result from modernization in the Soviet Union of the 1950s and 1960s.

A mathematical model is proposed that describes the processes of electrooxidation of metal nanoparticles localized on the surface of an indifferent macroelectrode. In contrast to previously proposed models based on geometric factors (shapes of particles and diffusion zones), the proposed model has introduced thermodynamic considerations which take into account the energy differences between the nanoparticle ensembles from microparticles and macroparticles. A series of voltammograms was obtained as a result of calculations and characteristic relationships between the different parameters were found. An analysis of the findings, on the one hand, predicts the shape and characteristic features of the experimental voltammograms and, on the other hand, provides information regarding energetic properties of the nanoparticles. © 2009 Springer-Verlag.

The paper proposes a mathematical model describing electrooxidation of a polydisperse system of metal nanoparticles from the surface of an indifferent macro-electrode. It is shown that the degree of dispersion of a nanoparticle ensemble affects the shape of oxidation voltammograms. When the degree of dispersion rises and the average size of nanoparticles becomes smaller, the range of oxidation potentials increases. The results of the experimental study of electrooxidation of gold nanoparticles with different degrees of dispersion are given. The particles were localized on the surface of graphite screen-printed electrodes. A good agreement between the parameters of the experimental and calculated voltammograms confirms the correctness of the proposed model. © 2012 Springer-Verlag.

It is shown that nanoparticles localized on a foreign solid electrode may display two opposite shifts of dissolution potential, namely, a shift toward either more positive or more negative values as compared with the equilibrium potential of M n+/M 0 or the potential of bulk metal electrooxidation. The observed phenomena are interpreted in view of three energy states of substance, which are realized depending on contribution of the surface Gibbs free energy (ΔG°) to the energy of the system. Literature data concerning different metalsubstrate pairs and specially conducted experimental investigations of electrooxidation of gold nanoparticles (radius equal to 10 and 150 nm), which are localized on the surface of glassy carbon, bulk gold, and platinum electrodes are presented and discussed. A shift of maximum current potential of small nanoparticles oxidation toward more positive values is observed in this series. The oxidation potential of large nanoparticles is not affected by the nature of the substrate. In all cases, electrooxidation of gold nanoparticles occurs at the more negative potentials than those of the bulk gold electrooxidation. It is shown that depending on the nature of the substrate and nanoparticle size, the dominating effect is either interaction of nanoparticles with the substrate (ΔG°<0) and electrochemical potential shifts toward positive values or impact of surface Gibbs free energy of nanoparticles (ΔG°>0) into energy of the system and electrochemical potential shifts toward negative values. The validity of the proposed assumptions is confirmed by good correlation of literature and our experimental data with calculated ones. © Springer-Verlag 2012.

Carbon screen-printed electrodes (CSPE) are used as substrate for bismuth nanoparticles immobilization. Sensors modified with bismuth nanoparticles of different origin (prepared by the method of gas condensation and chemically synthesized) are used to determine nickel by adsorptive stripping voltammetry (AdSV). The effect of the structural organization of nanoparticles on sensor sensitivity is studied. It is established that chemically synthesized nanoparticles of bismuth, which form agglomerates of about 380 ± 76 nm on the electrode surface, demonstrate optimal sensory properties. Direct current (DC) voltammetric stripping response is linear and is observed within the range from 0.85 × 10- 8 to 8.48 × 10- 8 M Ni(II) (deposition time - 120 s). The detection limit is 3.2 nM, precision is good (RSD = 4.8% at 5.0 × 10- 8 M Ni(II), n = 14). © 2011 Elsevier B.V. All rights reserved.

A focus of the paper is a problem of "observability" regarding food security. Known scientific approaches to identification of a similar condition have not provided us with a grounded solution to refer to actual borders of security (or standards of mutual penetration). Their absence makes methodological capacities of modelling essentially disturbed. It is levelling of these contradictions that is an aim of this research. The authors put forward and give a scientific rationale for a hypothesis for fragmentary food security, an essence of which is come down to a research on certain agricultural commodity groups. In a critical review, features of security are specified. A theoretical development of authors' provisions have resulted in formalization of a number of models built in terms of the dependence factor or inherent openness of the food system. These and other features have made it possible to offer a distinctive technique for an analytical interpretation of findings, including an assessment of risk for lost security condition in a food aspect of the issue.
