Convergence of economic growth in Russian megacities

Purpose: The article presents the results of an empirical analysis of the economic growth of Russian cities with a population of over 1 million people (megacities). Design/Methodology/Approach: The analyzed indicator is the city product calculated according to the UN methodology for the period from 2010 to 2016. The paper analyses the process of β- and σ-convergence across Russian megacities using methods of spatial econometrics in addition to the traditional β-convergence techniques from the neoclassical theoretical framework. Findings: The dynamics of the coefficient of variation confirmed the presence of σ-convergence in city product. Empirically, positive spatial autocorrelation has been confirmed. Beta-convergence for Russian megacities is found to be significant and the spatial location of megacities significantly affects β-convergence. Control factors such as fixed capital investment per capita in 2010, average retail volume per capita in 2010, average annual number of employees of enterprises and organizations in 2010 and the dummy variable introduced for “federal cities” Moscow and St. Petersburg are all found to have positive and statistically significant impact on economic growth. Practical Implications: Policymakers may take the results into account under the planning of economical strategies for megacities and regions in Russia in order to facilitate the regional economic growth and the speed of convergence. Originality/Value: The main contribution of the study is the consideration of the economical growth for the megacities and not for the regions as it often used to be the case in similar studies. The important finding is that megacities‘ economies do converge and the influence of control factors is pronounced.peer-reviewe

Managing the motivation provision of universities in the context of the educational process digitalisation

The paper proposes a method for increasing the motivation of university teachers to work with digital technologies on the example of teaching foreign languages. The fear of complete displacement of the teacher by digital technologies leads to many ethical and psychological problems, resulting in a reluctance to use training programmes in the educational process. To increase the motivation of teachers to work in the digital environment, it is proposed to involve them in the use of digital educational technologies to adapt the work plans of disciplines to the preparation level of students entering universities. The specialists team composition required for the implementation of this method in practice has been formed. Additional factors for increasing the teachers motivation to work in a digital environment when working in a team have been shown. The proposed approach can be used in the implementation in digital educational systems of educational institutions

Metal-insulator transition induced by 16O -18O oxygen isotope exchange in colossal negative magnetoresistance manganites

The effect of 16O-18O isotope exchange on the electric resistivity was studied for (La(1-y)Pr(y))0.7Ca0.3MnO3 ceramic samples. Depending on y, this mixed perovskite exhibited different types of low-temperature behavior ranging from ferromagnetic metal (FM) to charge ordered (CO) antiferromagnetic insulator. It was found that at y=0.75, the substitution of 16O by 18O results in the reversible transition from a FM to a CO insulator at zero magnetic field. The applied magnetic field (H >= 2 T) transformed the sample with 18O again to the metallic state and caused the increase in the FM transition temperature Tc of the 16O sample. As a result, the isotope shift of Tc at H = 2 T was as high as 63 K. Such unique sensitivity of the system to oxygen isotope exchange, giving rise even to the metal-insulator transition, is discussed in terms of the isotope dependence of the effective electron bandwidth which shifts the balance between the CO and FM phases.Comment: 5 pages (RevTeX), 2 eps figures included, to appear in J.

TRUST AS A VIRTUAL TEAM EFFECTIVENESS FACTOR

A relatively new phenomenon in management practice – a virtual team has been considered. Based on a study of a wide range of domestic and foreign sources, it has been shown, what problems arise during the formation and operation of virtual teams. Attention on the problem of mutual trust in the team has been focused. It has been concluded that the lack of common social norms and opportunities for mutual control, the lack of direct personal contacts, cross-cultural problems, and the lack of informal communication impede confidence building. However, the rapid idealization of a communication partner, the ability to create the effect of physical presence with minimal means can contribute to building trust and team spirit. The article is addressed to specialists in the field of personnel management and all interested in modern technologies of labor management

Catalyzed decay of false vacuum in four dimensions

The probability of destruction of a metastable vacuum state by the field of a highly virtual particle with energy $E$ is calculated for a (3+1) dimensional theory in the leading WKB approximation in the thin-wall limit. It is found that the induced nucleation rate of bubbles, capable of expansion, is exponentially small at any energy. The negative exponential power in the rate reaches its maximum at the energy, corresponding to the top of the barrier in the bubble energy, where it is a finite fraction of the same power in the probability of the spontaneous decay of the false vacuum, i.e. at $E=0$.Comment: 9 pages (standard LaTeX)+ 3 figures (one figure in LaTeX, two are appended in PostScript).
