The role of customer service in increasing the competitive ability and competitiveness of service organizations

The essence of service and service as a product of the service business, including the core of the service, its customized variants, atmosphere, architecture and contact personnel, has been characterized. It has been found out that customer orientation is a key characteristic of a business in the service sector and reflects a combination of understanding of its strategic vectors, its essential characteristics and the vision of the organization through the eyes of the client (internal - employee and external - consumer). It has been determined that a customer-oriented service consists in focusing attention on the customer, rather than on a product-centered marketing strategy. The components of a successful customer-oriented service have been highlighted, based on the quality of services provided, the level of accompanying service, the range of services provided and the availability of after-sales service. It has been noted that nowadays there is a shift in the relationship between sellers and buyers from onetime transactions to long-term partnership relations

COMPARATIVE ANALYSIS OF THE CONCEPTS OF «COMPETITIVE STABILITY» AND «COMPETITIVENESS» OF SERVICE ORGANIZATIONS

A comparative analysis of the categories, that form the concepts of competitiveness and competitive stability in relation to the organization of the services sector, has been conducted. The main approaches to the definition of categories and concepts, such as «competitive position», «competitive status», «competitive potential», «competitive advantages» have been analyzed. Their clarifications regarding the organizations of the service sector have been made. Based on the conducted comparative analysis, the concept of competitive advantages has been formulated as a basis for the formation of competitiveness and potential competitive stability of the organization of the services sector

INTERNET TECHNOLOGIES AS A FACTOR OF INCREASING THE COMPETITIVENESS AND COMPETITIVE STABILITY OF SERVICE ORGANIZATIONS

Presently, the use of Internet technologies is an absolute advantage on the way to the successful functioning of an enterprise in any sphere of economy. The increasing unpredictability of the external environment, the variability of consumer preferences are increasingly transforming competition in the markets of goods and services, from the industrial to the information plane. Under such conditions, the role of internal factors of enterprise competitiveness increases. In recent decades, the introduction of such technologies in service enterprises has become increasingly widespread, ranging from simple tools (e-mail or messengers) to global introduction in the business structure ( using electronic commerce or creating virtual enterprises). We are not even talking about the newest complex developments in the field of Internet technologies, but about the use of existing and simpler ones, which are increasingly used by enterprises. The basic directions of application of Internet technologies and advantages which a business entity in the service sector receives from it have been considered in the article

Dynamics of the Free Surface of a Conducting Liquid in a Near-Critical Electric Field

Near-critical behavior of the free surface of an ideally conducting liquid in an external electric field is considered. Based on an analysis of three-wave processes using the method of integral estimations, sufficient criteria for hard instability of a planar surface are formulated. It is shown that the higher-order nonlinearities do not saturate the instability, for which reason the growth of disturbances has an explosive character.Comment: 19 page

Development Of Software–Hardware System for Real Time Simulation of Electric Power System with Smart Grids

The design and research of electric power system (EPS) with smart grids (SG), which are the current world trend of modern electric power industry, requires solving a large number of non-trivial tasks. The developed technical solutions and used equipment are novel for the world practice. Therefore, their implementation requires carefulanalysis and an individual approach to research that provides an assessment of the impact of new network elements on the power system. All of this puts requirements on the tools and methods of research used to solve such problems. At present, digital systems for modelling EPS with SG based on the application of numerical methods are used as such tools. However, despite the high level of these developments, it has drawbacks. The use of incomplete and invalid information obtained by digital tools can lead to the wrong design and operational decision in real power system, which can cause blackouts. The alternative approach for solving the problem of detailed simulation of EPS with SG is the creation of hybrid system based on the principle of combining different modelling methods. Hybrid Real-Time Power System Simulator (HRTSim) is developed based on this approach and presented in the paper

Search for electron antineutrino interactions with the Borexino Counting Test Facility at Gran Sasso

Electron antineutrino interactions above the inverse beta decay energy of protons (E_\bar{\nu}_e>1.8) where looked for with the Borexino Counting Test Facility (CTF). One candidate event survived after rejection of background, which included muon-induced neutrons and random coincidences. An upper limit on the solar $\bar{\nu}_{e}$ flux, assumed having the $^8$B solar neutrino energy spectrum, of 1.1$\times10^{5}$ cm$^{-2}$~s$^{-1}$ (90% C.L.) was set with a 7.8 ton $\times$ year exposure. This upper limit corresponds to a solar neutrino transition probability, $\nu_{e} \to \bar{\nu}_{e}$, of 0.02 (90% C.L.). Predictions for antineutrino detection with Borexino, including geoneutrinos, are discussed on the basis of background measurements performed with the CTF.Comment: 10 pages, 9 figures, 5 table

Profile of subpopulation composition of regulatory T lymphocytes and intestinal microbiota in patients with irritable bowel syndrome

The following specificcharacteristics of the composition of intestinal microbiota in patients with irritable bowel syndrome (IBS) were identified using a metagenomic analysis (16 S rRNA): 1) an increase in the representation of Actinobacteria, including Bifidobacterium spp., Firmicutes, including representatives of Streptococcaceae (Streptococcus), Lachnosperaceae (Dorea), Veillonellaceae (Dialister), Proteobacteria (Enterobacteriaceae and Desulfovibrionaceae families); 2) a decrease in the population of Bacteroidetes, including representatives of the families Prevotellacea (Prevotella spp.), Bacteroidaceae (Bacteroides spp.). Firmicutes belonging to the families Clostridiaceae and Ruminococcaceae (Fecalibacterium spp.).Flow cytometry in the study of the subpopulation composition of T regulatory (Treg) lymphocytes in patients with IBS revealed an increase in the number of CD45R0+CD62L+ central memory cells (CM), which can regulate the processes of maturation and differentiation of lymphocytes in lymphoid tissue. A decrease in the expression of exonucleases CD39 and CD73 was detected, which can have a significant effect on their activity. A reduction in effector memory cells (EM) Treg was observed.Changes in the expression level of exonucleases CD39 and CD73 were inversely correlated with the content of Proteobacteria and the representation of the genera Bifidobacterium spp. and Faecalibacterium spp. The content of СЫ Treg was directly correlated with the content of Dorea spp.The results may be indicative of impairment in the processes of Treg differentiation, which are closely related to changes in key components of intestinal microbiocenosis in IBS

Pulse-Shape discrimination with the Counting Test Facility

Pulse shape discrimination (PSD) is one of the most distinctive features of liquid scintillators. Since the introduction of the scintillation techniques in the field of particle detection, many studies have been carried out to characterize intrinsic properties of the most common liquid scintillator mixtures in this respect. Several application methods and algorithms able to achieve optimum discrimination performances have been developed. However, the vast majority of these studies have been performed on samples of small dimensions. The Counting Test Facility, prototype of the solar neutrino experiment Borexino, as a 4 ton spherical scintillation detector immersed in 1000 tons of shielding water, represents a unique opportunity to extend the small-sample PSD studies to a large-volume setup. Specifically, in this work we consider two different liquid scintillation mixtures employed in CTF, illustrating for both the PSD characterization results obtained either with the processing of the scintillation waveform through the optimum Gatti's method, or via a more conventional approach based on the charge content of the scintillation tail. The outcomes of this study, while interesting per se, are also of paramount importance in view of the expected Borexino detector performances, where PSD will be an essential tool in the framework of the background rejection strategy needed to achieve the required sensitivity to the solar neutrino signals.Comment: 39 pages, 17 figures, submitted to Nucl.

New limits on heavy sterile neutrino mixing in 8B{^{8}\rm{B}}-decay obtained with the Borexino detector

If heavy neutrinos with mass $m_{\nu_{H}}\geq$2$m_e$ are produced in the Sun via the decay ${^8\rm{B}} \rightarrow {^8\rm{Be}} + e^+ + \nu_H$ in a side branch of pp-chain, they would undergo the observable decay into an electron, a positron and a light neutrino $\nu_{H}\rightarrow\nu_{L}+e^++e^-$. In the present work Borexino data are used to set a bound on the existence of such decays. We constrain the mixing of a heavy neutrino with mass 1.5 MeV $\leq m_{\nu_{H}} \le$ 14 MeV to be $|U_{eH}|^2\leq (10^{-3}-4\times10^{-6})$ respectively. These are tighter limits on the mixing parameters than obtained in previous experiments at nuclear reactors and accelerators.Comment: 7 pages, 6 figure
