Improving the methodological tools of market pricing in exhibition marketing

Purpose: The purpose of the study is to determine ways to improve the methodological pricing tools in exhibition marketing from market positions. Design/Methodology/Approach: The leading method of research is a systematic approach, which is used to substantiate the economic and mathematical model of the optimal market price of the exhibition area, which is set depending on the quality of the exhibition. In order to measure differences in the quality of exhibition events, authors proposed to use reference-exhibition benchmarking characterized by the best price / quality ratio. Findings: The results of the study form the methodological basis for improving pricing not only in the exhibition business, but also in other areas of business activity. This is possible if the goods (services) are produced in the conditions of a monopolistic competition, and the quality of an individual product (service) could be quantified in a conventional unit, which should be scientifically substantiated. Practical implications: This study is of practical value for both exhibition organizers and their participants. Using of expo-activities of the developed methodological tools of market pricing allows strengthening their competitive positions and increasing the profitability of exhibitions, if the optimal market price of the exposition calculated by the proposed method compensates the average total costs of the exhibition company. Originality/Value: The article substantiates the original conceptual approach to exhibition pricing, which is based on interaction marketing, benchmarking and extremely high price, which prevents the formation of demand from exhibitors, that is proposed to be called the alternative price. It becomes possible to provide a scientific basis for determining the optimal market price of the exhibition area, that maximizes the profit of the organizing company.peer-reviewe

Stress and arterial hypertension: ISIAH rat strain

The main views of the issue of stress and hypertension are briefly reviewed. It is well known that stress is one of the major risk factors for cardiovascular disease development. Increase in blood pressure is a typical manifestation of the acute stress response. This fact is the reason to hypothesize that chronic stress causes the development of hypertensive disease. An association of hypertension with psychological stress in humans was shown in several works. In addition, it was demonstrated that hypertension was accompanied by an increase in sympathetic tone. On the other hand, there were many population studies in which no association was found between different types of chronic stress and arterial hyper­tension. Thus, the question is far from being answered. Even in the cases when one managed to obtain a signi­ficant hypertensive effect in experimental studies with emotional stress, it was difficult to explain the mechanisms mediating the formation of stressinduced hypertension. To clarify the situation, one of the authors of this review decided to begin the breeding of a rat strain with increased blood pressure response to emotional stress. This breeding gave rise to inbred rats with persistent stress-induced arterial hypertension. A brief history of the development of the genetic model ofstress-induced arterial hypertension, the ISIAH rat strain, is given. A retrospective review of the studies performed with ISIAH rats is presented. The contribution of genotype changes in the neuroendocrine systems involved in stress and blood pressure regulation to the development ofstress-dependent hypertension in the ISIAH rat strain is shown

Nearby Doorways, Parity Doublets and Parity Mixing in Compound Nuclear States

We discuss the implications of a doorway state model for parity mixing in compound nuclear states. We argue that in order to explain the tendency of parity violating asymmetries measured in $^{233}$Th to have a common sign, doorways that contribute to parity mixing must be found in the same energy neighbourhood of the measured resonance. The mechanism of parity mixing in this case of nearby doorways is closely related to the intermediate structure observed in nuclear reactions in which compound states are excited. We note that in the region of interest ($^{233}$Th) nuclei exhibit octupole deformations which leads to the existence of nearby parity doublets. These parity doublets are then used as doorways in a model for parity mixing. The contribution of such mechanism is estimated in a simple model.Comment: 11 pages, REVTE

The ART-XC telescope on board the SRG observatory

ART-XC (Astronomical Roentgen Telescope - X-ray Concentrator) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observatory. The SRG observatory is the flagship astrophysical mission of the Russian Federal Space Program, which was successively launched into orbit around the second Lagrangian point (L2) of the Earth-Sun system with a Proton rocket from the Baikonur cosmodrome on 13 July 2019. The ART-XC telescope will provide the first ever true imaging all-sky survey performed with grazing incidence optics in the 4-30 keV energy band and will obtain the deepest and sharpest map of the sky in the energy range of 4-12 keV. Observations performed during the early calibration and performance verification phase as well as during the on-going all-sky survey that started on 12 Dec. 2019 have demonstrated that the in-flight characteristics of the ART-XC telescope are very close to expectations based on the results of ground calibrations. Upon completion of its 4-year all-sky survey, ART-XC is expected to detect ~5000 sources (~3000 active galactic nuclei, including heavily obscured ones, several hundred clusters of galaxies, ~1000 cataclysmic variables and other Galactic sources), and to provide a high-quality map of the Galactic background emission in the 4-12 keV energy band. ART-XC is also well suited for discovering transient X-ray sources. In this paper, we describe the telescope, results of its ground calibrations, major aspects of the mission, the in-flight performance of ART-XC and first scientific results.Comment: 19 pages, 30 figures, accepted for publication in Astronomy and Astrophysic
