Social aspects of migrants’ adaptation in Russia in the digital economy

The state, due to its socio-economic nature, must regulate and control the most important social processes. Migration is an important part of these processes, since the attraction of additional labor resources will give a certain impetus to the sustainable development of the country and ensure long-term economic growth. However, the implementation of migration policy is associated with a whole range of problems. The problems of social and digital adaptation of migrants, social and territorial disunity are among them. Added to this is the lack of effective interaction between public authorities and municipalities with civil society institutions, as well as the presence of a clear bias in ensuring equal opportunities in obtaining public services, depending on the level of income, migration status and other factors. The weak role of civil institutions in social and cultural adaptation and the language barrier also exacerbate the situation. The dominance of unskilled personnel in the structure of migration flows aggravates their digital adaptation. The digitalisation of many processes could have a signifcant impact in solving these problems. With its help, an effective institutional environment would gradually form. This article examines the social aspects of migrants’ adaptation in the context of digitalization. In the course of the research, the author conducted a comprehensive analysis, including observations, expert interviews and analysis of regulatory documents. The paper considers various aspects of the adaptation of migrants within the framework of political, socio-economic, psychological, national and demographic problems. As the study showed, in the context of digitalization it is necessary to form a fundamentally new institutional environment in the feld of adaptation of migrants in the host country. A qualitatively different regulatory framework, new institutions that harmonize the interests of the state, civil society, business and migrants should become a part of this environment

Ensuring the economic security of the country in the new geopolitical realities

The issue of ensuring Russia’s economic security is an important and priority task, especially in the tightening conditions of the consolidated sanctions policy of the European Union countries and the United States. The process of developing measures that allow Russian economy to develop sustainably and effectively counter the growing geopolitical threats is complex and requires a comprehensive and honest assessment, including the import dependence degree of business, the degree and level of involvement in global supply chains, the development level of domestic production, etc. For each assessment area, indicators should be identified that have a preventive nature and make it possible to detect a growing potential threat. In the research theoretical provisions on economic security are considered; existing threats to economic security in geopolitical realities are formulated; indicators presented by the Federal State Statistics Service are identified that allow assessing the threat degree; directions for ensuring economic security are developed

Modern trends of digitalization of innovation process

The purpose of this article is to identify modern aspects and problem areas in the field of digitalization of the innovation process. Digital technologies are becoming an increasingly important component of the various functional areas of the organization, and in some situations, the success of a business project. Digital technologies open great prospects for the conduct of various kinds of business, allow organizing international cooperation with minimal costs, thus accelerating globalization, stimulating development and expanding the boundaries of the world economic space.The wide use of digital technologies allows for the networking between the participants in the innovation process, ensures the formation of competitive advantages, optimizes the use of economic and other types of resources, and also enhances coordination and communication. Unfortunately, in Russia the level of application of digital organizations, in comparison with foreign organizations of developed countries, remains at a low level. In our country, the need for the use of information technology has matured long ago, but only since May 2017 the relevant regulatory documents have been issued that encourage organizations to actively digitize all areas and functional areas of their activities. Modern information technologies are characterized by high computing power, they take control of the organization, production, creation of innovations to a fundamentally different quality level.Currently, the success of competition is determined by the ability of organizations to quickly implement and commercialize innovations and obtain superprofits, in this regard it seems relevant to explore the possibilities of digital solutions and technologies for the effective management and management of innovation.The article analyzes the current state of the information technology industry and the information and communication technologies industry, on the basis of which the problems of the industry development have been identified, and proposals have been developed to use digital products to stimulate the innovation process

Color Octet Contribution to J/psi Photoproduction Asymmetries

We investigate $J/\psi$ photoproduction asymmetries in the framework of the NRQCD factorization approach. It is shown that the color octet contribution leads to large uncertainties in the predicted asymmetries which rules out the possibility to precisely measure the gluon polarization in the nucleon through this final state. For small values of the color octet parameters being compatible with $J/\psi$ photoproduction data it appears possible that a measurement of $J/\psi$ asymmetries could provide a new test for the NRQCD factorization approach, on one hand, or a measurement of the polarized gluon distribution from low inelasticity events $(z<0.7)$, on the otherComment: 12 pages, LaTeX, with 6 figs.

Multiple Interactions and the Structure of Beam Remnants

Recent experimental data have established some of the basic features of multiple interactions in hadron-hadron collisions. The emphasis is therefore now shifting, to one of exploring more detailed aspects. Starting from a brief review of the current situation, a next-generation model is developed, wherein a detailed account is given of correlated flavour, colour, longitudinal and transverse momentum distributions, encompassing both the partons initiating perturbative interactions and the partons left in the beam remnants. Some of the main features are illustrated for the Tevatron and the LHC.Comment: 69pp, 33 figure

Direct measurement of the mass difference between top and antitop quarks

We present a direct measurement of the mass difference between top and antitop quarks (dm) in lepton+jets top-antitop final states using the "matrix element" method. The purity of the lepton+jets sample is enhanced for top-antitop events by identifying at least one of the jet as originating from a b quark. The analyzed data correspond to 3.6 fb-1 of proton-antiproton collisions at 1.96 TeV acquired by D0 in Run II of the Fermilab Tevatron Collider. The combination of the e+jets and mu+jets channels yields dm = 0.8 +/- 1.8 (stat) +/- 0.5 (syst) GeV, which is in agreement with the standard model expectation of no mass difference.Comment: submitted to Phys. Rev.

Measurement of the t-channel single top quark production cross section

The D0 collaboration reports direct evidence for electroweak production of single top quarks through the t-channel exchange of a virtual W boson. This is the first analysis to isolate an individual single top quark production channel. We select events containing an isolated electron or muon, missing transverse energy, and two, three or four jets from 2.3 fb^-1 of ppbar collisions at the Fermilab Tevatron Collider. One or two of the jets are identified as containing a b hadron. We combine three multivariate techniques optimized for the t-channel process to measure the t- and s-channel cross sections simultaneously. We measure cross sections of 3.14 +0.94 -0.80 pb for the t-channel and 1.05 +-0.81 pb for the s-channel. The measured t-channel result is found to have a significance of 4.8 standard deviations and is consistent with the standard model prediction.Comment: 7 pages, 6 figure

Measurement of trilinear gauge boson couplings from WW + WZ to lnu jj events in pp-bar collisions at sqrt{s}=1.96 TeV

We present a direct measurement of trilinear gauge boson couplings at gammaWW and ZWW vertices in WW and WZ events produced in pp-bar collisions at sqrt{s}=1.96 TeV. We consider events with one electron or muon, missing transverse energy, and at least two jets. The data were collected using the D0 detector and correspond to 1.1/fb of integrated luminosity. Considering two different relations between the couplings at the gammaWW and ZWW vertices, we measure these couplings at 68% C.L. to be kappa_{gamma}=1.07^{+0.26}_{-0.29}, lambda =0.00^{+0.06}_{-0.06} and g_{1}^{Z}=1.04^{+0.09}_{-0.09} in a scenario respecting SU(2)_L x U(1)_Y gauge symmetry and kappa =1.04^{+0.11}_{-0.11} and lambda=0.00^{+0.06}_{-0.06} in an "equal couplings" scenario.Comment: 14 pages, 7 figures, published in Phys.

Measurements of differential cross sections of Z/gamma*+jets+X events in proton anti-proton collisions at sqrt{s}=1.96 TeV

We present cross section measurements for Z/gamma*+jets+X production, differential in the transverse momenta of the three leading jets. The data sample was collected with the D0 detector at the Fermilab Tevatron proton anti-proton collider at a center-of-mass energy of 1.96 TeV and corresponds to an integrated luminosity of 1 fb-1. Leading and next-to-leading order perturbative QCD predictions are compared with the measurements, and agreement is found within the theoretical and experimental uncertainties. We also make comparisons with the predictions of four event generators. Two parton-shower-based generators show significant shape and normalization differences with respect to the data. In contrast, two generators combining tree-level matrix elements with a parton shower give a reasonable description of the the shapes observed in data, but the predicted normalizations show significant differences with respect to the data, reflecting large scale uncertainties. For specific choices of scales, the normalizations for either generator can be made to agree with the measurements.Comment: Published in PLB. 11 pages, 3 figure
