Gender inequality in the hotel industry

Recently, the hospitality industry is getting developed in the modern economy that works within the national economics movement of the service field. Hospitality brings not only income to the state, but also creates jobs that enable people to get employed as with the higher education as without that. According to the State Statistics Committee of March 2016 in Ukraine, there are 1218 hotels, in common with all hostels and sanatoriums, amount of which is more than 3200. This is due to the dynamic development and popularity of the hotel business, while in Ukraine this kind of business is not good enough. Since the hotel business goes on a level with the largest export branches of the world economy, such as automobile manufacturing and oil production, the investors believe that Ukrainian hospitality is promising, with opportunity to enter international networks, such as Hilton

Enhancement of non-equilibrium thermal quantum discord and entanglement of a three-spin XX chain by multi-spin interaction and external magnetic field

We investigate the non-equilibrium thermal quantum discord and entanglement of a three-spin chain whose two end spins are respectively coupled to two thermal reservoirs at different temperatures. In the three-spin chain, besides the XX-type nearest-neighbor two-spin interaction, a multi-spin interaction is also considered and a homogenous magnetic field is applied to each spin. We show that the extreme steady-state quantum discord and entanglement of the two end spins can always be created by holding both a large magnetic field and a strong multi-spin interaction. The results are explained by the thermal excitation depression due to switching a large energy gap between the ground state and the first excited state. The present investigation may provide a useful approach to control coupling between a quantum system and its environment.Comment: 16 pages, 10 figure

q-Functional Wick's theorems for particles with exotic statistics

In the paper we begin a description of functional methods of quantum field theory for systems of interacting q-particles. These particles obey exotic statistics and are the q-generalization of the colored particles which appear in many problems of condensed matter physics, magnetism and quantum optics. Motivated by the general ideas of standard field theory we prove the q-functional analogues of Hori's formulation of Wick's theorems for the different ordered q-particle creation and annihilation operators. The formulae have the same formal expressions as fermionic and bosonic ones but differ by a nature of fields. This allows us to derive the perturbation series for the theory and develop analogues of standard quantum field theory constructions in q-functional form.Comment: 15 pages, LaTeX, submitted to J.Phys.

A STUDY OF EXTREMISM AS A COMPLEX INTER-BRANCH CONCEPT

Purpose: The aim of the study is to investigate extremism as a complex inter-branch concept which complicates law enforcement practice. Methodology: This is an analytic-dialectical research whose data are obtained through the analysis of historical, legal and sociological texts and data. Main Findings: When defining extremism in the basic law of anti-extremist legislation, it is necessary to proceed from the fact that the phenomenon, the concept of which should be formulated, is manifested in different spheres of social and political life. In conclusion, extremism creates an ideological basis for terrorism, but the acts of terrorism go beyond the concept of extremism. Applications: This article can be used by regional schools, cultural organizations and universities. Novelty/Originality: In this study, correlation between the phenomena of terrorism and extremism has been studied on the basis of definition for terrorist act given in part 1 of article 205 of the criminal code of the Russian Federation

Spin dynamics in semiconductors

This article reviews the current status of spin dynamics in semiconductors which has achieved a lot of progress in the past years due to the fast growing field of semiconductor spintronics. The primary focus is the theoretical and experimental developments of spin relaxation and dephasing in both spin precession in time domain and spin diffusion and transport in spacial domain. A fully microscopic many-body investigation on spin dynamics based on the kinetic spin Bloch equation approach is reviewed comprehensively.Comment: a review article with 193 pages and 1103 references.
