The article describes the problem of convergence of technical and eco-nomic education through the use of marketing categories. The scheme of inter-action and interpenetration of scientific disciplines at the present stage of devel-opment of society is also presented in the article. The article examines the evolu-tionary forms of the fundamental categories of marketing – the rate of use-value, and the mechanism of convergence of technological and economic education in a bipolar economy.
From anthropological point of view culture is the product of acting humans. Human nature is created by culture and is determined by it. Language is the most important part of cultural and national identity. It develops dynamically decoding traditional values and beliefs, and those connected with modern culture. Moreover, it reveals convergence or an impact of one culture over another that is generated in different languages. To compile “converged” lexical entries it is necessary to show not only how the languages encode a particular experience of the world or how extra linguistic or cultural realia is interpreted but also what fosters their differences to be leveled.
The current analysis is based on cognitive approach that can be useful to see the implicit assumption that is embedded within the mental maps or frames of norms and values of this or that culture and to view a kind of correlation in a lexical unit. Each item is supplied with a definition to reveal its semantics, pragmatics and socio-cultural sources of their generation. It is also important to discover what significant concepts are not shared by other cultural groups. To be more precise some converged items are examined diachronically and synchronically. Among them phraseological units, neologisms and even non-equivalent items are to be taken into consideration first of all.
In this paper we study convergence among Russian regions. We find that while there was no convergence in 1990s, the situation changed dramatically in 2000s. While interregional GDP per capita gaps still persist, the differentials in incomes and wages decreased substantially. We show that fiscal redistribution did not play a major role in convergence. We therefore try to understand the phenomenon of recent convergence using panel data on the interregional reallocation of capital and labor. We find that capital market in Russian regions is integrated in a sense that local investment does not depend on local savings. We also show that economic growth and financial development has substantially decreased the barriers to labor mobility. We find that in 1990s many poor Russian regions were in a poverty trap: potential workers wanted to leave those regions but could not afford to finance the move. In 2000s (especially in late 2000s), these barriers were no longer binding. Overall economic development allowed even poorest Russian regions to grow out of the poverty traps. This resulted in convergence in Russian labor market; the interregional gaps in incomes, wages and unemployment rates are now below those in Europe. The results imply that economic growth and development of financial and real estate markets eventually result in interregional convergence.
The historical changes in Central and Eastern Europe demanded suitable paths for the transition from centrally planned to market based economies. The lack of relevant experience added to the challenge, giving rise to the incalculable risks of implementing untested policies. By focusing on monetary policy, trade, and convergence, this volume addresses some of the most urgent economic policy issues in the transition economies of Central and Eastern Europe and beyond.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
By using superconducting quantum interference device (SQUID) magnetometry, we investigated anisotropic high-field (H less than or similar to 7T) low-temperature (10 K) magnetization response of inhomogeneous nanoisland FeNi films grown by rf sputtering deposition on Sitall (TiO2) glass substrates. In the grown FeNi films, the FeNi layer nominal thickness varied from 0.6 to 2.5 nm, across the percolation transition at the d(c) similar or equal to 1.8 nm. We discovered that, beyond conventional spin-magnetism of Fe21Ni79 permalloy, the extracted out-of-plane magnetization response of the nanoisland FeNi films is not saturated in the range of investigated magnetic fields and exhibits paramagnetic-like behavior. We found that the anomalous out-of-plane magnetization response exhibits an escalating slope with increase in the nominal film thickness from 0.6 to 1.1 nm, however, it decreases with further increase in the film thickness, and then practically vanishes on approaching the FeNi film percolation threshold. At the same time, the in-plane response demonstrates saturation behavior above 1.5-2T, competing with anomalously large diamagnetic-like response, which becomes pronounced at high magnetic fields. It is possible that the supported-metal interaction leads to the creation of a thin charge-transfer (CT) layer and a Schottky barrier at the FeNi film/Sitall (TiO2) interface. Then, in the system with nanoscale circular domains, the observed anomalous paramagnetic-like magnetization response can be associated with a large orbital moment of the localized electrons. In addition, the inhomogeneous nanoisland FeNi films can possess spontaneous ordering of toroidal moments, which can be either of orbital or spin origin. The system with toroidal inhomogeneity can lead to anomalously strong diamagnetic-like response. The observed magnetization response is determined by the interplay between the paramagnetic-and diamagnetic-like contributions.

The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
