Ownership Structures

In this paper, we analyse the effects of the massive Russian privatisation programme on the ownership of Russian firms and on the behaviour of formerly state owned enterprises. A large random sample of Russian firms is used to investigate the emerging ownership structures, patterns of control and enterprise behaviour. We find that workers have become the dominant owners in a majority ig Russian private firms; 65% of the total as against 19% being manager owned and 16% of being outsider owned. Higher- ownership appears to confer significantly more influence over decision-making on managers and outsiders, but not on workers. Most importantly however, we find no evidence that privatisation affects any major area of enterprise behaviour or performance.

Technologies for remote lidar sensing of the surface to detect low concentrations of hydrocarbons in Siberia and the far north

The results of research in the field of remote sensing using the technologies of radar and laser detection of hydrocarbons raw materials aimed at the search, localization and topographic location of discovered oil and gas field, the determination of leaks and atmospheric pollution by hydrocarbon gases (e.g. methane) are presented. The main problems with sounding are revealed. To determine the extremely low concentrations of methane in the atmosphere, the main constraining factors were determined and the need to suppress side interference arising on the probing path of the laser beam was shown. To formulate requirements for the sensitivity of equipment and the accuracy of software calculations, the choice of a mathematical model of the path of the laser beam is justified. A modification of the known model is proposed to represent the lidar path based on the differential absorption method taking into account correction coefficients of molecular and aerosol absorption and scattering. Thus, the presented model is a set of methods for providing more accurate and localized data for the implementation of a hardware-software complex. © Published under licence by IOP Publishing Ltd

ГЕНДЕРНІ ОСОБЛИВОСТІ РЕСУРСНОСТІ ПОЛІЦЕЙСЬКИХ

The urgency of the chosen topic, which is related to the need to study the potential of police officers of both sexes, has been outlined. The latest research on the chosen issues of Ukrainian and foreign scholars has been analyzed, and the objective of the article was to present the results of an empirical study of gender characteristics of psychological potential of police officers. According to the results of the study, the authors have revealed a lack of gender differences in the level of psychological potential within studied persons: 68% of future patrol police officers have a high level of potential; 27% has the studied persons with the average level of psychological potential of sample group; and the smallest – about 5% – is the group with low level of psychological potential. The gender features of potential have been revealed: formed with psychological resources in the group of women are “work on themselves” and “love”, in the group of men – “success”. The most developed psychological resources in both groups of the studied persons were “self-realization in the profession”, “self-confidence”, “help to others” and “responsibility”, which can be considered as a factor of changes in both professional development and personal self-development. The relationships between the components of psychological potential and decision-making factors in the groups of studied persons have been established: the ability of women to update their own resources and the desire to creatively work on them increases their tendency to rationality, moderation and procrastination, and the presence of such gender-colored features as sensitivity, empathy and openness to people, predetermine the probability of implementing such decision-making factor as “avoidance”. Actualization of the ability to use own resources of men and the desire for self-realization strengthens their ability to take responsibility and diligence, allows to choose the most appropriate options for behavior and rational decisions, decreasing conformism; in a situation of decision-making they are prone to productive coping “vigilance”. The obtained data allow to study sources of potential of police officers (both men and women), to determine the ways to optimize their psychological potential and provide an opportunity to more effectively organize the psychological support of their professional activities.Актуальність теми пов’язана з потребою вивчення ресурсності працівників поліції обох статей. Представлено результати емпіричного вивчення гендерних особливостей психологічної ресурсності працівників поліції, серед яких виявлено такі: у групі жінок сформованими психологічними ресурсами є «робота над собою» та «любов», у групі чоловіків – «успіх». Установлено взаємозв’язки між компонентами психологічної ресурсності та факторами прийняття рішень у групах досліджуваних: чоловіки схильні до продуктивного копінгу «пильність», жінки частіше орієнтуються на копінг «уникнення»

Влияние контроля над бронхиальной астмой на кардиоваскулярные нарушения у детей раннего школьного возраста

The course of bronchial asthma (BA) is accompanied by pathological changes in the bronchopulmonary and cardiovascular systems. The severity of heart functional disorders depends on the severity of the BA Course, the level of control and the frequency of application of short-acting β2 -agonists (SAβ2A). The aim of the study was to analyze the impact of BA control on the development of cardiovascular disorders in children of early school age. Methods. Children (n = 95) aged 7–12 years with BA of varying severity and different levels of control were examined. The analysis of indicators of the clinical and functional state of the vegetal nervous system (VNS) and cardiovascular system tone using standard electrocardiography, echocardiography with calculation of the left ventricular myocardial mass index, сardiointervalography was performed. Results. Changes in VNS with signs of its depletion and decrease in adaptive capacity, cardiac rhythm and conduction disorders, connective tissue dysplasia syndrome, hemodynamic disorders and signs of adaptive heart remodeling have been detected. Conclusion. Lack of control over BA and the use of SAβ2A promote cardiovascular disorders.Течение бронхиальной астмы (БА) сопровождается патологическими изменениями бронхолегочной и сердечно-сосудистой систем (ССС).

Role of portocaval shunts in development of complications after liver transplantation

Rationale. Portal blood flow is a key component in the viability of the liver transplant. Portocaval shunts formed on the background of the liver cirrhosis before transplantation can cause portal vein steal syndrome, with subsequent development of ischemic necrosis of the graft. To date, the tactics of treating patients with portal vein steal syndrome during liver transplantation has not been sufficiently developed. This paper presents a literature review and our own experience on this important, but little-studied issue. Purpose. The purpose of this research is to study the role of portocaval shunts in the development of complications after liver transplantation, based on a retrospective analysis of clinical cases. Conclusions. In liver transplantation, portocaval shunts can cause the development of portal vein steal syndrome with subsequent development of liver failure. For the diagnosis of portal vein steal syndrome, it is important to use the data obtained at all stages of liver transplantation. Surgical correction of portal vein steal syndrome can be performed during liver transplantation and in the early postoperative period. © 2022 by the authors

Efficacy and safety of lebrikizumab in adult patients with mild-to-moderate asthma not receiving inhaled corticosteroids

Background: Asthma is a heterogeneous and complex disease in both its clinical course and response to treatment. IL-13 is central to Type 2 inflammation and contributes to many features of asthma. In a previous Phase 2 study, lebrikizumab, an anti-IL-13 monoclonal antibody, did not significantly improve FEV1 in mild-to-moderate asthma patients not receiving ICS therapy. This Phase 3 study was designed to further assess the efficacy and safety of lebrikizumab in adult patients with mild-to-moderate asthma treated with daily short-acting β2-agonist therapy alone. Methods: Adult patients with mild-to-moderate asthma were randomised to receive lebrikizumab 125 mg subcutaneously (SC), placebo SC, or montelukast 10 mg orally for 12 weeks, with an 8-week follow-up period. The primary efficacy endpoint was absolute change in pre-bronchodilator FEV1 from baseline at Week 12. Findings: A total of 310 patients were randomised and dosed in the study. The mean absolute change in FEV1 from baseline at Week 12 was higher in the lebrikizumab-treated arm compared with placebo (150 mL versus 67 mL); however, this improvement did not achieve statistical significance (overall adjusted difference of 83 mL [95% CI:-3, 170]; p = .06). Montelukast did not improve FEV1 as compared with placebo. Lebrikizumab was generally safe and well tolerated during the study. Interpretation: Lebrikizumab did not significantly improve FEV1 in mild-to-moderate asthma patients at a dose expected to inhibit the IL-13 pathway. Inhibiting IL-13 in this patient population was not sufficient to improve lung function. These data support the findings of a previous trial of lebrikizumab in patients not receiving ICS
