The Covid-19 pandemic has made financial performance in a company undergo several changes. Activities of some companies have decreased, increased, or even tended to be unstable when compared to before and after the pandemic. The purpose of this study is to analyze the impact of gender diversity, CEO business experience, and financial leverage on the financial performance of companies in the transport and hospitality industry in Indonesia, Thailand, and Malaysia for the period 2015-2020. The sample in this study is transport and hospitality companies in Indonesia, Malaysia, and Thailand for the 2015-2020 period that are registered with the Compustat database. A sample of 25 companies during the 6-year study period (2015-2020) makes 150 samples. The authors use secondary data, namely data from the Compustat database and websites of companies. Data analysis includes the following steps: normality test, multicollinearity test, multiple linear regression analysis, t-test. Data analysis was performed in the STATA v.16.0 application – statistical software for data science. The results of the multiple linear regression equation show that the direction of the influence of gender diversity, debt to equity ratio, and interest coverage ratio on the financial performance of companies in the transport and hospitality industry is positive and significant. Meanwhile, the CEO's Business Expertness and debt ratio variables harm the financial performance of companies. Therefore, investors should pay attention to external and internal factors that affect the financial results of the company before investing in its activities.

The insurance industry is one of the important components of the world financial system because it provides economic protection for the society. Risk-based capital is a certain amount of capital that insurance companies must have on hand in order to hedge against their risks. This capital is there to make sure that the company can maintain solvency, and can fulfill all of its financial operating needs. This study aims to determine the factors that influence Risk-based capital (RBC) as the level of solvency of insurance companies in Indonesia. These factors are generally divided into 2 groups: internal factors (company characteristics) and external factors (macroeconomic factors). Internal factors consist of such variables as premium and liquidity. External factors consist of such variables as economic growth (GDP) and interest rates. The sample of this study is presented by 12 insurance companies that listed on the Indonesia Stock Exchange (IDX). The study covers the period from 2014 until 2019. The analysis method used in this study is multiple regression with the Fixed Effect Model (FEM) approach using Eviews software version 9.0. This method is used to analyze the effect of independent variables towards the dependent variable. The research results showed that the liquidity variable had a significant positive effect on risk based capital. At the same time the interest rate variable has a significant negative effect on risk based capital.

Bank Rakyat Indonesia (BRI) is one of the largest banks in the country with a fleet of over ten thousand bank branches. The bank is one of the biggest microfinance lenders in the country and is committed to accelerating financial inclusion in Indonesia through digital transformation. Agent BRILink, a nationwide network of branchless agents, enables Bank BRI to reach rural Indonesia. BRILink agents are bank customers who have a high-reliability score (calculated using the banks’ big data) and who maintain a minimum balance of USD 800. The agents can open a bank account, facilitate withdrawals, and disburse loans. The purpose of this study is to explore the agent's motivation to become a BRILink agent and the level of customer trust on the BRILink agents in the North Jakarta Administrative City. The sample for this study was BRILink agents in the North Jakarta Administrative City, among them: micro product marketing officers at BRI Pertamina Sindang Unit, BRILink Agent Officers at BRI Branch Office Jakarta Tanjung Priok, Managers in the BRI Head Office and customers of BRILink Agents. The data collection methodology for this study includes observations, surveys and interviews, as well as analysis of random questionnaires provided to 177 BRILink agents located in the of North Jakarta Administrative City. The survey data were processed using SPSS (Statistical package for the social sciences). It was revealed that the motivation to become the BRILink agent is based on the agent's desire to provide more convenient customer service by providing more services, which ultimately will increase the turnover of all bank services. This motivation can be closely related to business concerns in creating customer trust. Improving the quality of service in the event of a complaint will increase customer loyalty and encourage them to continue to do business with the BRILink agent. Improving the work of BRILink agents in terms of the quantity and quality of services will lead to better results of the bank's activities, since these processes are interrelated.

Reduced intensity conditioning (RIC) transplantation is increasingly offered to older patients with acute myeloblastic leukemia. We have previously shown that a RIC allograft, particularly from a sibling donor, is beneficial in intermediate-risk patients aged 35-65 years. We here present analyses from the NCRI AML16 trial extending this experience to older patients aged 60-70 inclusive lacking favorable-risk cytogenetics. Nine hundred thirty-two patients were studied, with RIC transplant in first remission given to 144 (sibling n=52, matched unrelated donor n=92) with a median follow-up for survival from complete remission of 60 months. Comparisons of outcomes of patients transplanted versus those not were carried out using Mantel-Byar analysis. Among the 144 allografted patients, 93 had intermediate-risk cytogenetics, 18 had adverse risk and cytogenetic risk group was unknown for 33. In transplanted patients survival was 37% at 5 years, and while the survival for recipients of grafts from siblings (44%) was better than that for recipients of grafts from matched unrelated donors (34%), this difference was not statistically significant (P=0.2). When comparing RIC versus chemotherapy, survival of patients treated with the former was significantly improved (37% versus 20%, hazard ratio = 0.67 [0.53-0.84]; P<0.001). When stratified by Wheatley risk group into good, standard and poor risk there was consistent benefit for RIC across risk groups. When stratified by minimal residual disease status after course 1, there was consistent benefit for allografting. The benefit for RIC was seen in patients with a FLT3 ITD or NPM1 mutation with no evidence of a differential effect by genotype. We conclude that RIC transplantation is an attractive option for older patients with acute myeloblastic leukemia lacking favorable-risk cytogenetics and, in this study, we could not find a group that did not benefit.

Published: October 2021

BACKGROUND: The objectives were to assess the prevalence, severity, and medication taken, and to look for predictive factors in order to better identify characteristics of passengers at risk of motion sickness during transport from Hobart in Tasmania to the French polar stations in Antarctica.

METHODS: There were 239 passengers who were surveyed over 4 yr with 4 round trips per year using the Motion Sickness Susceptibility Questionnaire (MSSQ), Simulator Sickness Questionnaire (SSQ), state-trait anxiety test (STAI-Trait and STAI-State), and general parameters (age, gender, number of trips, jet-lag, direction of the trip), medication, calculation of the distance of each passenger’s cabin to the center of gravity (CoG).

RESULTS: While the passengers had a low intrinsic sensitivity to motion sickness (MSSQ), 94% reported at least one SSQ symptom of motion sickness, and 38% vomited. Five associated factors were discovered: greater initial sensitivity (MSSQ), anticipation of being ill, younger age, higher level of anxiety at midtrip, and greater distance from the CoG. Of the passengers, there were 54% who took anti-motion sickness medication at different times of the trip, however, these passengers experienced more nausea. This could be due to self-selection since they were more sensitive to motion sickness.

CONCLUSION: We identified three predictive factors of motion sickness (greater intrinsic susceptibility, younger age, and greater cabin distance from the CoG). For preventive purposes, two associated factors of MS (anticipation of being ill, MSSQ score) were determined to classify three groups of risk of MS to improve passenger care during the trip.

Analysing the Effectiveness of the Nigerian Law and Policy in Promoting Renewable Energy and Expanding Access to Electricity
Authors: Alonge Funmi
Published: October 2021

Access to electricity is a major challenge in Nigeria with adverse effects on residents and businesses. To improve the poor state of electricity, the government introduced several policies to enhance the use of renewable energy in addition to existing conventional energy resources. However, the use of renewable energy has been relatively low in Nigeria. This can be attributed to several factors such as inconsistency in renewable energy targets, non-implementation of policies and lack of political will. In order to address this, the use of incentives as in the case of Texas is proposed for Nigeria.
Export Credit Agencies, International Investment Law and the Spectre of Unsustainable Developing Countries' Debts
Authors: Heard Jonathan , Laryea Emmanuel T.
Published: October 2021

This article argues that the activities of Export Credit Agencies (ECAs), which provide political risk insurance to cover exports and foreign direct investments (FDIs), may be undermining the goals of Investor-State Dispute Settlement (ISDS). ISDS is supposed to limit investment disputes so that they are between the investor and host-state of the investment (investor-state disputes). However, since ECAs are quasi-governmental organisations that support FDIs, they can effectively elevate such investment disputes so that they are between the host-state and home-state of the investor (state-to-state disputes). This has implications for the necessity defence in international investment disputes, which is likely to feature in cases triggered by governmental measures taken in response to the COVID-19 pandemic. Further, the article argues that the activities of ECAs often precipitate unsustainable debt accumulation in developing countries. And these situations are becoming increasingly combustible because ECAs have escalated their activities to season investment programmes with foreign and geopolitical influence. This may worsen in the aftermath of the COVID-19 pandemic. The article concludes that increased transparency and a sustainability element in the activities of ECAs are essential to both expose these risks more broadly and to create a space under the canopy of international economic law for more sustainable growth from the understory of developing nations.

The article is devoted to the study of changes in the intensity of traffic flows in the street canyons of Kyiv and to determine the dynamics of the intensity of emissions of major pollutants during the day. Due to the rapid growth of the vehicle fleet, there is a significant congestion of the street and road network of cities, which leads to a set of environmental problems. One of the such problems is air pollution with harmful substances. Object of the study: dynamics of pollution of city streets Purpose of the study: study of changes in traffic intensity during the day and assessment of the dynamics of the level pollution of the cities road network. Method of the study: statistical methods, cluster analysis. The change in the level of pollution of city streets during the day depends on dynamic factors, namely the intensity and quality of the traffic flow, meteorological conditions and so on. It is established that the most dangerous intervals of the day will be "peak" periods during which the maximum values of traffic intensity are observed. The article examines the patterns of distribution of traffic intensity during the day and on the basis of determining the environmental performance of real vehicles, technical and operational characteristics of which correspond to the characteristics of "efficient" cars of the corresponding category, determines the daily distribution of emissions of major pollutants. Thus, the obtained results can be used in determining the concentrations of pollutants in the street canyons of cities, which will make operational predictions of the level of air pollution.

The article is devoted to the development of technologies for modeling integration processes that synergistically affect the level of road safety of vehicles in terms of risk and uncertainty of non-stationary environmental factors. The mathematical description of the given sphere and information space of interaction of road users in the zones of the greatest probability of commission of road accidents is formalized that is shown by statistics of supervision. The essence, peculiarity and specificity of situational modes of dynamic, continuous interaction between road users, drivers and environmental factors in the space-time discrete cells of the electronic map of the critical zone on the basis of the frequency of previous accidents are substantiated. Analytical means of formation of transversal trajectories of safe movement without accidents and catastrophes are offered, which are guaranteed by the corresponding on-board information controlled complexes (BICC) of vehicles. Active targeted management within the system of navigation and control of mobile objects is implemented with a bias on the criteria to increase the level of road safety directly in the current critical area of the road network. A method of discrete dynamic programming of processes of synthesis and realization of controlled motion on a guaranteed safe transverse trajectory has been developed, which is locally applied only situationally within the transient mode of evasion from approach to threats with shock contacts. The technology of parameterization of predicted mutual maneuvering functions in the conditions of individual restrictions on the local space-time zone of own motion for a pair of vehicles that are really close to each other is formalized. BICC information and analytical tools ensure the reliability of estimates of the interval of endurance according to the prejudiced piecewise continuous transverse curve, which also provides local points of avoidance of collisions or the passage of forbidden local microzones. The only methods of modeling different vehicles by each BICC actively synthesize paired microphase spatial divisions of their own trajectories, which, due to the presence of risks, record the absence of traffic accidents with loss of safety within nonstationary flows due to the coordinated multiple heterogeneous interaction under similar conditions of field approximations.

Published: October 2021

The problem of optimizing the trajectories of deep curved oil and gas wells, in which the total curvature of the well and its length is minimized, is discussed. For the first time, a discrete-continuum model of the well geometry was proposed, based on the method of projection of a gradient on the hyperplane of linearized constraints, a method was developed for minimizing the corresponding target functionals, which would reduce the risks of emergency drilling situations. An algorithm for reducing the problem of nonlinear optimal control to the problem of nonlinear programming is shown. Such a transition is achieved by approximating the well trajectories with a system of cubic splines, analytically integrating differential equations in separate sections of the trajectory, and further applying the methods of nonlinear programming theory. The considered approach is more algorithmic and allows solving problems of well trajectory optimization under more complex constraints.

The article addresses directions and horizons in the creation of highly efficient specialized continuously operating earthmoving machines and provided a technical proposal for the multipurpose earthmoving machine. Study subject: continuously operating earthmoving machines. Objective: To create a power-efficient special-purpose earthmoving machine. Study method: experimental. Existing dimension-types of trenching excavators allow digging lengthy excavations of the assigned profile with minor deviations from their nominal width and depth. Creating of excavations of different profiles is being achieved via machine re-equipment with different implements. A sustainable solution is to create multipurpose earthmoving machines that are capable to perform lengthy excavations of various widths and depths with the same implement and without constructional alterations. There are known machine designs for trenching on the basis of a wheeled tractor with a mounted chain-bucket implement that is able to perform the lateral oscillatory displacements in relation to the vertical axis on the hull back of the tractor. Alteration of the implements oscilative motion amplitude allows to excavate the tranches of differnt width. This is the essence of the multipurpose earthmoving machine. The existing kinematics chain sections of the implement in relation to the tractore can't ensure the consistency of the machine load due to inconsistency of the borings along the width of excavation. This leads to significant pulsation of the load on the implement, loss of the longitudinal stability and, in the end, reduces the potential productivity of the machine by half. We have performed a set of studies in creating of the multipurpose earthmoving machines (MEM). As the experimental study objects we've used physical models of the MEM implements and full-size prototypes of the machines. Results of the study experimentally confirm the possibility to create a highly productive MEM with rotary implement, which efficiently performs trenches as well as wide construction pits in the mode of reciprocating approach of the rotary implement to excavation by means of equalization and minimization of power load parameters values.

The article considers the main symptoms and causes of accelerated motor oil aging in the gasoline engine operation. This process is revealed when conducting auto-technical expertise and is caused by motor oil being exposed to various constructive and operational factors. The object of the study is the automotive internal combustion engine affected by fuel and motor oil that have abnormal properties. The goal of the work is to develop a method that can be used for the tasks of auto-technical expertise and can help clarify the types and symptoms of various effects on motor oil, as well as determine the causes for the changes in its properties when the engine is running. The research method is experimental-theoretical and includes the analysis of a large amount of data that were obtained during auto-technical expert research and demonstrated how various factors affect motor oil properties. To solve the problem, an algorithm for logical analysis has been developed that determine the nature of motor oil exposure to fuel. It describes the causal relationships between the failure event and the underlying events that initiate the change in oil properties. A logical graph is obtained for the analysis of causal relationships and determination of the failure cause due to lack of bearing lubrication that occurs as a result of oil exposure to fuel, which includes the formation of deposits, sediment, changes in oil viscosity. The practical application of the method is most expedient in the tasks of auto-technical expertise of engine faults. The obtained results help avoid gross errors in determining the cause of the formation of sediment in oil and/or deposits on the walls. Based on large factual material, it has been determined that the processes of oil exposure to fuel are random. However, attempts to obtain a mathematical description of the problem in order of assess the probability of this type of failure are complex and do not lead to any useful equations for practical application. In such conditions, the use of the developed logical algorithm becomes the most expedient, especially when determining the causes of engine failures, when they are caused by the use of abnormal fuel.

The article is devoted to the identification of modern problems of logistics services in Ukraine. The article presents a number of factors that hinder the development of logistics services at domestic enterprises. It should be noted that logistics services are a process of creating benefits for the company. The object of research is logistics service processes. The purpose of the work is to investigate the main problems of logistics services of domestic enterprises. Research method - analysis and synthesis. For domestic enterprises, the introduction of efficient logistics services can be a significant competitive advantage. This is due to the fact that Ukrainian companies only indirectly address the issue of logistics services. Nevertheless, modern consumers are now paying more and more attention to the level of service, based on the experience of work with foreign companies that have a fairly high level of service. Therefore, before improving logistics services in enterprises, it is necessary to identify existing problems at the global and local levels. Global problems are problems of service at the state level, caused by the low level of the economy, ultra-rapid globalization, backwardness from the giant countries. Local problems are problems of logistics services at the level of the enterprise or branch, which are formed as a result of uneven distribution of profit, inefficient regulatory framework, lack of qualified personnel. This issue is covered in this article. The obtained results can be used in the improvement of logistics services at domestic enterprises.KEY WORDS: LOGISTICS SERVICE, LOGISTICS SERVICES, CONSUMER, LEVEL OF SERVICE.

The article aims to deepen the study of the economic and social impact of the coronavirus pandemic worldwide and in Slovakia. The sudden outbreak of the COVID-19 pandemic changed the usual stereotypes of government agencies, businesses, hospitals, schools and all other structures where people existed. The world has changed. Restraint measures have affected people's lives and the professional activities of both the public and private sectors of individual states. From a social point of view, the fate of many people has changed, many professions are unable to do their jobs due to restrictive measures, many people face a lack of their income, many people have suffered from the disease, many have succumbed. Mutations in the coronavirus mapped against the release of containment measures and thus hindered office work, school education, and the operation of all types of shops and services. A study of the impact of the Kovid pandemic on such industries as mining, food industry, textile, woodworking, chemical, pharmaceutical, metallurgy, computer manufacturing, machine building, vehicle manufacturing, energy supply, steam, gas and cold air. Almost all industries have reduced production. This was reflected in world trade. The slowdown in economic activity has created new challenges that countries have to deal with. The negative impact of the Pandemic was felt by the tourism industry, in particular in Slovakia. The coronacrisis caused the slow-down of the prices on the real estate market due to economic instability caused by the decrease of the disposable income of the households. The decline in economy caused by the pandemic forced states to prepare some safety measurements for employers and employees and self-employed persons as well. States have created various arrangements to help their economies go through. The Ministry of Employment of Slovak republic prepared the project called “The First Aid for Employees, Enterpreneurs and Self-Employed Persons” with the aim to prevent the increase of the unemployment rate in the tough times of coronacrisis. The Ministry of culture of Slovak republic has published the grant to help those self-employed persons working in the sector of the culture or the creative industry whose netto income was not higher than 540 EUR/month.

Представлены данные по городу Саранску, полученные в рамках проводимой ИЭА РАН долгосрочной антропогенетической программы исследования процессов воспроизводства в популяциях РФ. Показано, что в семьях городских популяций Поволжья практикуется регулируемый тип рождаемости. Выявлено резкое возрастание вклада небиологических факторов в величину коэффициента отбора. Применение искусственной регуляции репродукции влияет на процессы воспроизводства в популяциях. Репродукция выступает в роли универсального индикатора социального и биологического здоровья общества.
The paper presents the data on the city of Saransk, obtained in the course of the long-term anthropogenetic program of research on reproduction processes in the populations of the Russian Federation conducted by the IEA RAS. It is shown that fertility is controlled among the families of urban populations in the Volga region. A sharp increase in the contribution of non-biological factors to the value of the coefficient of selection is revealed. Artificial reproduction regulation affects the reproduction processes in populations. Reproduction acts as a universal indicator of social and biological health of society.
