Under-five mortality is a leading indicator of child health and overall development of a country. Sub-Saharan Africa remains the region with the highest under-5 mortality rate in the world, with 1 child in 13 dying before his or her fifth birthday. Half of all under-five deaths in 2019 occurred in just five countries: Nigeria, India, Pakistan, the Democratic Republic of the Congo, and Ethiopia. In Ethiopia, as the 2016 Ethiopia Demographic and Health Survey (EDHS) report showed that the under-five mortality declined from 166 deaths per 1,000 live births in 2000 to 67 deaths per 1,000 live births in 2019 mini EDHS report (60% decreasing rate). However, there are regional disparities problems on under-five children mortality in Ethiopia. Thus, the major purpose of this study was to model the multilevel effects of U5 child time to death, and to determine the risk factors for child’s death based on the last full report (2016 EDHS). The data were analysed using descriptive statistics, stratified Cox proportional hazards regression and multilevel parametric survival models. In the study, 635 (6.1%) U5 deaths have observed from 10,331 children. And, the overall probability of survival was 0.93. Results obtained by fitting both stratified Cox proportional hazards regression and lognormal parametric fixed-effect models: sex of child, type of birth, birth order, size (weight) of child at birth, months of breastfeeding, number of U5 and five children, family size, wealth index, frequency of listening radio, place of delivery place of residence, and geographical region were found to be significant factors for U5 children death or estimated mean survival time. Furthermore a high risk death of U5 children was found to be associated with male children, twined children, ≤ 6 months breastfeeding children, few number of children in the home, children from small family size, children average weight below, children from poor families, private health sectors delivered children, children from mothers didn’t not listen radio, children from rural areas, children from Afar, Somali and Harari regional states. In the lognormal parametric random effects model, 1.7 and 0.9 estimated variations were observed among regional and household cluster levels on U5 children mean survival times. The researchers recommended that governments, and other concerned bodies should give special supports for mothers whose children are at high risk of death.

Foreign investment is an essential factor in increasing the competitiveness of the national economy in our days. Investment is considered to be the main prerequisite for the social development, but the investment process faces many obstacles and problems not allowing to make it efficient and orderly. Intensification of investment processes is a priority objective of companies on the way to the sustainable development and enhanced competitive positions in the market environment. The investment attractiveness has critical significance in it, as its dynamism depends on the company’s ability to meet the terms of potential investors. In focus of the article are issues of attracting foreign capital as an important factor in accelerating technical progress and improving the company performance. The essence, types and significance of foreign investment in the context of globalization processes, relationships between the investment climate characteristics and the company competitiveness are determined. Factors of the investment capital reproduction increasing the capital cost at two levels, macro- and microeconomic, are discussed. An analysis of the performance and prospects of foreign investment in the Ukrainian business sector in the context of financial and economic globalization is made; the need for investment to ensure the company competitiveness in the conditions of economic crisis is justified. Approaches to the classification of factors determining investment climate and investment attractiveness were improved, which are defined at the macroeconomic and microeconomic level and involve their relationship and interaction. An analysis of interactions between transformation processes in the Ukrainian economy and investment activities revealed a correlation of the investment climate and the investment level with the company competitiveness on the market.

Education sectors at country level rely on the circulation of large scopes of information pertaining to education institutions, research institutions, pupils and students, teaching staff, researchers, education diploma or certificates etc. Therefore, the register systems allowing to systematize this information, file it in a convenient form, edit and communicate to physical persons whom these data belong, and to support administrative decision making constitute a necessary tool for the satisfaction of information needs of the modern society. The registers (databases) of the education sector are integral components of the online information resource system in developed countries, which usually consists of the two subsystems: registers containing information about the population, and business registers. The greatest progress in creating online information resource system, according to experts from international organizations, has been achieved in North European countries. These countries have also become pioneers in carrying out population censuses on the basis of registers, including ones in the education sector. The article’s objective is to sum up the practices of North European countries in creating and operating electronic information resource systems in the education sector for its adaptation in the Ukrainian realities. The education registers (databases) of Denmark, the Netherlands, Norway, and Estonia are discussed, with making comparison of register systems in six North European countries. It is stressed that Denmark has created the most elaborate register system operated by the line ministry and the statistical office, in the Netherlands and Norway only two education registers exist, containing the necessary information on all the education levels of the population, Estonia has the single information system for the education, and in Sweden and Finland separate registers for each education level have been created. All the above mentioned register systems in education have sufficient information content, and they are continuously improved. And most importantly, these education registers (databases) in all the studied countries are linked by personal identifiers of individuals with other registers containing information about the population. The process of creating the Unified State Electronic Database on Education in Ukraine is analyzed, with elaborating on the registers included in this system and their content. Conclusions and recommendations on improvements and further developments in education registers of Ukraine and their links with other population-specific registers are made by summing up the practices of creating electronic information resource systems in North European countries.

The purpose of this paper is to make a comparative analysis (find historical parallels) of the situation with mortality causes in four cities of Ukraine in 1923–1929 and in our time, by comparing the mortality structure in 1926 and 2019, to identify structural changes and make assumptions regarding their determinants. Based on data from statistical tables of mortality in the four largest cities of the Ukrainian Socialist Soviet Republic (Kyiv, Kharkiv, Dnipropetrovsk, and Odessa) for 1923–1929 and data from the State Statistics Service of Ukraine for 2019 on the distribution of deaths by death cause in the same cities and in Ukraine, the structural shares by main classes were calculated (according to the current classifications). Changes in the contribution of various causes of death to the mortality of the urban population are estimated. The overall progress (the advancement of medical science and practice, the improvement of living conditions (including sanitation and hygiene) and quality of life, the increased population’s awareness of health issues and access to medical care, etc.), immunization programs, the development and production of effective drugs have significantly reduced the mortality and transformed its structure. It is shown that the list of the leading causes, especially their ranks, given in the research of Yu. O. Korchak-Chepurkivsky, differed significantly from the analogous list for modern metropolises of Ukraine. In contrast to the situation in the four largest Ukrainian cities in 2019, with the majority of deaths caused by diseases of the circulatory system (about 65%), almost the same total share (67.4%) of deaths in the above cities in 1926 was determined by five classes (infectious or communicable diseases, diseases of the respiratory and digestive organs, cardiovascular diseases, and diseases of the nervous system and sense organs). The largest share of deaths in the four largest cities of the Ukrainian Socialist Soviet Republic was found to be caused by infectious and parasitic diseases (over 27%). Given that part of the infectious pathology (the diseases of the digestive system and nervous system in the first place) was registered by the then nomenclature in other classes, their contribution to the totality of deaths can be assessed as more significant (at least by 10–15%). The structural share of mortality from infectious and parasitic diseases in the four largest cities has decreased from 27% altogether to nearly 2%. There was a significant transformation in the spectrum of causes: while in 1926 high mortality was due to scarlet fever, whooping cough, typhoid fever and paratyphoid fever evolved to almost zero, in our time its significant part was caused by a new pathology, a disease caused by the human immunodeficiency virus (HIV). At the same time, the significance of tuberculosis as a cause of death is a striking difference between the mortality pattern in Ukrainian cities and the situation in modern developed c

Climate change is one of the most serious threats to the society, economy and environment in the whole world and Ukraine in particular. The central objective for the environmental statistics today is to perform the sound statistical assessment, to develop or improve new or existing approaches to building up the system for accounting of the indicators measuring climate change and adaptation to it. The improvement or development of existing or new methodologies and methods for the statistical accounting and assessment of climate change indicators is the only way for the production of information in a sound and comprehensive manner. It is argued that the statistical analysis allows deepening the grasp into the operation of a complex and dynamic phenomena as climate change, elaborate actions to reduce its adverse environmental effect, and eliminate adverse consequences of climate change for our planet. It is found that the official statistics have been put the ever stronger focus on issues of environmental performance and climate change by concentrating on the development and improvement of methodologies and procedures for compilation of environmental accounts that are used for economic measurements of natural resources, energy, waste, water resources, air emissions, spending for environmental protection. It is stressed the United Nations Statistical Commission has adopted, at global level, the System of Environmental-Economic Accounting (SEEA) designed to provide important support to the development of statistics related with climate change by intensifying the effort in several dimensions of the complex economic and environmental accounting. The industry coverage of the climate change statistics is defined, with a detailed description of various approaches to the environmental accounting in which indicators of climate change are involved. The significance of the environmental-economic accounting (and the account of air emission of dangerous substances in particular) as the central source of data on greenhouse gas emissions in Ukraine is substantiated. In spite of many functions in the measurement of climate change, assigned to the national statistics system, the existing official statistics does not always employ its capacities for the assessment of climate change. By considering the statistics on climate change as a tool with impact on decision-making in this field, the authors outlined the areas of improvements in the accounting of climate and climate change.

Analysis of financial processes is an important and fast developing branch of statistics. Statistical analysis is a combined analysis. Statistical methodology refers to a system of techniques and methods aimed at studying quantitative patterns in the dynamics and relationships of socio-economic phenomena. The main feature of the statistical methodology is also the specificity of research, expressed in the inextricable connection of quantitative analysis with the establishment of a qualitative uniqueness of objects in the concrete historical conditions of place and time. The use of the techniques of mathematical statistics and other branches of mathematics (applied, in particular) becomes a technical means of implementation. Lebanese stock market today is inactive and is shrinking. Historically, Lebanon had a relatively vibrant capital market in the Middle East before the stock exchange was closed for twenty years due to the civil war (1975-1995). Since its reopening in 1996, the stock market has been contracting. The establishment of Solidere in late 1990s and the renaissance of commercial banks energized the stock market for a while before the volatility of the market hold back. The article analyzed the change in the main indicators of the Lebanese stock market for the period from 2012 to 2019. The study developed a statistical model for the decomposition of time series, which was led to identify the trend, seasonal, cyclical and random components.. The simulation results made it possible to establish the patterns of changes in the share prices of the three leading enterprises representing the construction, industrial and banking sectors of the Lebanese economy. The length and depth of short-period cycles in the studied indicators time series were measured. It was found that the depth of cyclical fluctuations increases with decreasing stock prices of Lebanon’s construction and industrial enterprises under the influence of both economic and political processes, while the cyclic recurrence of stock prices in the banking sector was less pronounced and was mainly determined by changes in the economy

Intensification of the integration processes in education helps increase the quality of the international education and enhance the striving of youth to receive education services abroad. The economic cooperation of Ukraine with EU countries is gradually taking shape, resulting in the rapidly growing demand of Ukrainian students for education in European higher education establishments (HEEs). The European education system is a global leader in training highly skilled staff due to the implementation of dual training which founder was German. The practice of combined training and internship has spread across Europe and gained extreme popularity in Polish HEEs, thus laying grounds for the increasing demand for their graduates. In focus of the article is the international education migration of young Ukrainians, first and foremost to Poland, with highlighting the advantages of training in this country that has been recognized as the most optimal one on the European area with respect to professional training. This is due to several reasons: first, the overwhelming majority of Ukrainian graduates from Polish HEEs showed professional competencies and mental fitness for work in companies and enterprises across EU; second, Poland is one of the most attractive foreign partners and investors of Ukraine, which promotes rapid development of collaborative Ukrainian-Polish projects. Poland has been working hard in the latest years to develop and improve the system of education services for foreigners, beginning with language courses for training of professionals with various qualification levels and scientific degrees. The received education services, apart from being an effective means for professional and individual development, can help in the carrier promotion at companies in Poland and beyond. The study covers a social-psychological and economic-statistical analysis of the education migration of Ukraine in the latest years, with determining a range of factors that caused one’s choice of other country for getting education services, and investigating the consequences of Ukrainians’ travels abroad for education purposes.

The economic cooperation of Ukraine with EU countries is gradually taking shape, resulting in the rapidly growing demand of Ukrainian students for education in European higher education establishments (HEEs). The European education system is a global leader in training highly skilled staff due to the implementation of dual training which founder was German. The practice of combined training and internship has spread across Europe and gained extreme popularity in Polish HEEs, thus laying grounds for the increasing demand for their graduates. \u0000In focus of the article is the international education migration of young Ukrainians, first and foremost to Poland, with highlighting the advantages of training in this country that has been recognized as the most optimal one on the European area with respect to professional training. This is due to several reasons: first, the overwhelming majority of Ukrainian graduates from Polish HEEs showed professional competencies and mental fitness for work in companies and enterprises across EU; second, Poland is one of the most attractive foreign partners and investors of Ukraine, which promotes rapid development of collaborative Ukrainian-Polish projects. Poland has been working hard in the latest years to develop and improve the system of education services for foreigners, beginning with language courses for training of professionals with various qualification levels and scientific degrees. The received education services, apart from being an effective means for professional and individual development, can help in the carrier promotion at companies in Poland and beyond.

The article is devoted to the problem of socio-economic indicators estimation of at the local level, first and foremost at the municipal and community level. Emphasis is made on approaches to the estimation of the households’ disposable income as a key indicator of the population’s standards of living, required for elaborating and implementing effective measures of socio-economic policy, implementing investment programs on the modernization of living quarters, objects of social infrastructure etc. The meaning of the term “disposable incomes” adopted in the official statistics of Ukraine, drawbacks of this definition and ways for its extension are illustrated. A broad description of studies focused on the assessment of population’s incomes at local level in various countries of the world is given. It is shown that the need for such problem solutions in the statistics caused the emergence of a separate theoretical field – small area statistics. A series of international and national projects aimed at the adaptation of elaborated theoretical and methodological approaches have been accomplished, in particular SAMPLE in EU countries and SAIPE in the U.S. Basically, results of the performed studies demonstrate a feasibility of the assessment of households’ incomes at local level with the acceptable degree of reliability. A review of the main data sources that can be used for estimation of households’ incomes at local level in Ukraine is made. It is stressed that data from administrative registers on salaries, pensions, stipends, social allowances, subsidies for utility services, taxes etc. have critical importance for the income assessment. Special sample surveys of households’ incomes and expenditures, performed at local or regional and national level, are highly significant for determining the patterns of correlations between incomes and principal characteristics of households, such as composition, region and locality of residence, type of dwelling, availability of movable and immovable property, land plots etc. It is substantiated that methods for quantitative estimation of disposable incomes should be given preference over expert assessment that tends to be used in the current conditions. Examples of the assessment of disposable incomes based on quite simple and comprehensible ratios are given. Areas of further studies focused on the estimation of population incomes at the local level are outlined.

Breast cancer is most common tumour diagnosis for women worldwide. Over the last almost 40 years widespread adoption of mammographic screening has established Breast Conserving Surgery (BCS) followed by irradiation as the most practised treatment of choice. However, in absence of tools to determine the optimal quantum of tissue to be excised the debate continues for achieving a balance between the effectiveness of surgical intervention and the later stage personalisation of treatment, and so, a wide variation in practice is a common phenomenon globally. We attempt to introduce a definite measure that determines efficacy of BCS while protecting aesthetic value of life for Women affected with breast cancer. 74 mammography examinations and the surgical interventions of those women underwent for the management of breast cancer were used to compute the coefficient of lesion. In first step the lesion and the mammary gland proper are measured applying geometry. In the second step volume of tissue mass to be removed was calculated taking into account the measures from the 1st step and we present the coefficient of lesion mathematically. We empirically illustrated our methodological approach for determining the tissue mass to be excised. Conventionally, it is assumed that if the volume of tissues to be removed does not exceed 25% of the volume of the mammary gland, a Breast Conserving Surgery, is performed, however, our empirical illustration demonstrated that the established decision making parameter is not tenable for determining the extent / type of surgery undertaken. We have developed a coefficient aligned with the stage of the carcinoma and founded the base for developing a statistical (mathematical) model. Application of such a model accommodating tumour biology and patient characteristics shall not only provide intraoperative real time information to surgeons but also predict the prognosis of optimal surgical intervention of breast cancer. The next step is to develop a model using the data of the mammographic examination and the coefficient of breast lesion as covariates for determining the potentially effective volumes of surgical intervention needed, and plan reconstructive measures considering the effect of time on such intervention.

The Ukraine’s integration in the European and global education area and its implications for the academic mobility processes call for understanding the ways and prospects of modernization of the Ukraine’s strategy on exports of education services, strengthening of its position on the international market of education services, intensification of information efforts abroad aiming to convince potential students in the attractiveness of training in Ukraine and wide perspectives of the Ukrainian higher education. The article contains an analysis of the results from an empirical econometric and socio-psychological study devoted to the problems of academic mobility and education migration of Ukrainian youth and foreigners in Ukraine. A comparative analysis of the data shows that education migration processes have similar parameters for foreign students in Ukraine and Ukrainian abroad. The data on the attractiveness of the Ukrainian education for foreign students are analyzed as part of the study, with identifying the factors with impact on the scopes of student migration. The tendency of the continually increasing interest in higher education in Ukraine, in spite of the difficulties (political and economic) faced by Ukraine, is revealed, which is confirmed by the growing numbers of both foreign students in Ukraine and the higher education institutions in which they study. An analysis of the data shows that the education in Ukraine is the most attractive for post-soviet countries. Also, the numbers of education migrants coming from Africa and Asia, in particular from India, Morocco, Nigeria, Egypt, Israel, Jordan, Turkey, and Ghana, have been stably increasing in 2013–2019. An analysis of interviews reveals that foreign students go to study in Ukraine due to the following motives: the possibility to get high quality education (and return to a home country); low education fees compared with a home country; the optimal “price-quality” ratio etc. It was found out which specialties of the professional training drew special interest of foreign students. It is shown that the flows of education migration of Ukrainian students to other counties tended to intensify in the latest five years. The education migration was growing year-by-year in 2013/14–2017/18. According to the official statistical data on education migration recorded for 2017/2018, the number of Ukrainians taking education course in other countries reached 76181. The most attractive countries for training of Ukrainian youth and the essential factors behind their choice of country for education are defined. The estimated cost of education programs in selected countries that are the most attractive for Ukrainian youth is analyzed as of the academic period 2017/2018.
