In fact, globalisation causes major interdependence between economies of different countries, therefore, their economic relations influence the world economic climate. Countries develop strong business ties with their counterparts; national economies are integrated due to such factors as division of labour, internationalisation of monetary funds, scientific and technological progress, increasing degree of national economies openness and free trade. As a result, economies of different countries integrate into the worldwide reproduction process. International economic integration indicates a high development level of global economy. However, since single countries become exposed and highly susceptible to changes in economies of other states, the external environment is implied to present a significant uncertainty for commercial operations in single countries. Hence, in order to provide a stable functioning of both individual businesses and national economies it is necessary to analyse macro- and microeconomic parameters carefully, identify consistent patterns and make relevant predictions aimed at preventive management. The present article will discuss these challenges.peer-reviewe

    Implementation of controlling technologies as a method to increase sustainability of business activities

    Get PDF
    Purpose: We are currently facing that business environment is not stable due to globalisation processes in economics, cyclical changes and other disturbing factors. Hence, it is necessary to search such reserves that would improve efficiency of the business entity. Design/Methodology/Approach: The main objective of these reserves is to buffer negative impacts of external disturbances on financial and economic sustainability of enterprises. One of methods designed to improve the enterprise efficiency involves application of controlling technologies. Findings: In the present article the authors examine results of statistical analysis of economic performance of more than 70 Russian and foreign enterprises. The authors also analyse economic performance according to the authors’ integral indicator that shows effectiveness of implementation of the controlling system. Practical Implications: On the ground of this analysis, the authors determine the mean level of increase in efficiency of the enterprise's activity due to introduction of the controlling system. Originality/Value: The analysis proves that, on average, efficiency of the economic entity's operation increases by about 17%.South Ural State University is grateful for financial support of the Ministry of Education and Science of the Russian Federation (grant No 26.9677.2017/Π’Π ).

    Matching fields of a long superconducting film

    Full text link
    We obtain the vortex configurations, the matching fields and the magnetization of a superconducting film with a finite cross section. The applied magnetic field is normal to this cross section, and we use London theory to calculate many of its properties, such as the local magnetic field, the free energy and the induction for the mixed state. Thus previous similar theoretical works, done for an infinitely long superconducting film, are recovered here, in the special limit of a very long cross section.Comment: Contains a REVTeX file and 4 figure

    Non-Magnetic Spinguides and Spin Transport in Semiconductors

    Full text link
    We propose the idea of a "spinguide", i.e. the semiconductor channel which is surrounded with walls from the diluted magnetic semiconductor (DMS) with the giant Zeeman splitting which are transparent for electrons with the one spin polarization only. These spinguides may serve as sources of a spin-polarized current in non-magnetic conductors, ultrafast switches of a spin polarization of an electric current and, long distances transmission facilities of a spin polarization (transmission distances can exceed a spin-flip length). The selective transparence of walls leads to new size effects in transport.Comment: 4 pages, 2 figure

    The article considers some phenomena of the modern socio-cultural space from the standpoint of the discursive system of communicative philosophy. Of particular relevance to this study is the thought that the second half of the 20th century states the fact of the transition of the social system to a new level of social development, which can no longer act as post-industrial, but declares itself as informational. It is quite natural then to consider all the problematic aspects of the development and transformation of the socio-cultural space with methods, techniques and platforms related to the ideas developed in communicative philosophy. The article analyzes the impact of the axiological component on the consideration of such phenomena as value and value-based orientations, tolerance, identity, including Ego-identity, extremity, which, having anthropological roots, further lead to their own expression through a certain form of personality activity in society. The article concludes that, in order to minimize destructive and aggressive forms of social action, it is necessary to focus on the values of Dialogue and the β€œOther” in this dialogue, on authenticity as an opportunity to be oneself and to realize individual meaning, on a dynamic balance between β€œpleasant” and β€œmeaningful”

    Theoretical X-Ray Absorption Debye-Waller Factors

    Full text link
    An approach is presented for theoretical calculations of the Debye-Waller factors in x-ray absorption spectra. These factors are represented in terms of the cumulant expansion up to third order. They account respectively for the net thermal expansion Οƒ(1)(T)\sigma^{(1)}(T), the mean-square relative displacements Οƒ2(T)\sigma^2(T), and the asymmetry of the pair distribution function Οƒ(3)(T)\sigma^{(3)}(T). Similarly, we obtain Debye-Waller factors for x-ray and neutron scattering in terms of the mean-square vibrational amplitudes u2(T)u^2(T). Our method is based on density functional theory calculations of the dynamical matrix, together with an efficient Lanczos algorithm for projected phonon spectra within the quasi-harmonic approximation. Due to anharmonicity in the interatomic forces, the results are highly sensitive to variations in the equilibrium lattice constants, and hence to the choice of exchange-correlation potential. In order to treat this sensitivity, we introduce two prescriptions: one based on the local density approximation, and a second based on a modified generalized gradient approximation. Illustrative results for the leading cumulants are presented for several materials and compared with experiment and with correlated Einstein and Debye models. We also obtain Born-von Karman parameters and corrections due to perpendicular vibrations.Comment: 11 pages, 8 figure

    Collected are the data on sanitary-hygienic and parasitological aspects of rock pigeon vital activity in Saratov. Distinguished are the types of pigeon exterior pathologies, their character and frequency of occurrence. Synanthropic population and nests of the birds are searched for the presence of helminthes and ectoparasites. Identified is the role of nesting sites, located in attics of residential buildings, in sanitary and epidemiological situation of the city settlement zone

    Superconducting-coil--resistor circuit with electric field quadratic in the current

    Full text link
    It is shown for the first time that the observed [Phys. Lett. A 162 (1992) 105] potential difference Phi_t between the resistor and the screen surrounding the circuit is caused by polarization of the resistor because of the kinetic energy of the electrons of the superconducting coil. The proportionality of Phi_t to the square of the current and to the length of the superconducting wire is explained. It is pointed out that measuring Phi_t makes it possible to determine the Fermi quasimomentum of the electrons of a metal resistor.Comment: 2 pages, 1 figur
