The purpose of this study was to determine the degree of influence of alternative options for generating electricity by households on the level of energy independence of countries. The research methodology was based on the use of correlation–regression analysis, as well as adapted non-linear optimization by choosing one of three scenarios for electricity generation by households for 20 countries. Regression analysis showed the dependence of a country’s energy security on households’ energy independence. It is determined that an increase in households’ energy production helps to reduce the level of energy dependence in developed countries. However, for developing countries, there is no such interrelation. The solution of the formulated problem of nonlinear optimization for the studied countries has demonstrated that the criterion of energy dependence is superior to the criterion of a country’s energy security. In the long term, this study can be deepened in the direction of assessing the effectiveness of household investment in electricity generation projects. The proposed results can be used by responsible persons in the field of economy and energy in order to determine the position of various policies, and use strategic levers and indicators that ensure an effective response to energy security challenges in the regional and global markets.

Technology roadmaps are critical for decisions pertaining to technology development. They have been utilised in the renewable energy sector to assist in filtering alternative technology options in order to support energy policy formulation, energy security and energy independence, among others. However, solar aided power generation is a recent concept and no roadmap has been developed for the technology as yet. This paper thus reviewed the literature related to roadmapping with the aim of understanding the methods and tools that have been utilised in other settings. Informed by the literature, a conceptual framework was developed, which was further utilised for the initial analysis for developing a roadmap for solar aided power generation in South Africa. Generally, it would be beneficial for South Africa to integrate solar aided power generation within its current Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) or the National Treasury Public-Private Partnership (PPP) programme. However, it should be noted that this is only feasible in the short- and medium-term. In the long-term, there is a need to support stand-alone solar thermal technologies.

Coal has been a major contributor to energy security in many developed countries and is projected to continue contributing a significant fraction of global energy demand in the foreseeable future. Although coal power generation has been associated with numerous environmental implications, technological advances in the mining sector have enabled the mining of coal with minimal environmental impacts, especially in major coal-producing countries. In Kenya where inadequate energy supply is a major deterrent to economic growth, the discovery of coal reserves in the country presents a suitable opportunity for the country to address its energy security challenges. The challenge is how the exploitation of this resource can be done sustainably. This article explores the potential for sustainable coal mining in Kenya to address energy security challenges in the country. However, as it will be discussed in the paper, sustainable coal mining is often met with many challenges which include lack of finances, lack of technology, poor conditions of the physical environment, and unsupportive laws and regulations. Therefore, the article concludes that there are adequate ways and technologies that can be adapted in Kenya for sustainable coal mining. However, the decision as to whether coal mining should be embraced in the country should put into consideration the amount and nature of available coal reserves, availability of finances, availability of technologies, physical environmental conditions and the associated laws and regulations.

Energy Autonomy

The purpose of this study is to determine the impact of households’ energy autonomy on a country’s energy independence level, to identify prospects and risks. To assess the economic efficiency of households’ energy autonomy, the study used a modeling method based on maximizing the net present value, determining the average notional cost of energy efficiency and the level of energy independence in 20 countries. Based on the analysis of the volumes of electricity consumption by households in the studied countries for the period 2000–2018, it was revealed that in developed and developing countries there is an increase in this indicator. Diagnostics of the investment attractiveness of the installation and operation of energy systems for households makes it possible to determine the boundaries of a possible increase in the level of their energy autonomy. The scientific novelty of the research is represented by the proposed methodological approach, which makes it possible to assess the level of energy dependence of countries, possible deviations, and an increase in households’ energy autonomy in relation to the risk limit of energy dependence. The proposed methodological approach allowed the authors to prove the positive impact of increasing households’ energy autonomy for most developed countries. The most positive effect is characteristic of the leading countries in fossil energy market.

Summary Cardiovascular diseases (CVD) are the leading cause of invalidity and death in developed countries. Among them, the main cause of death is coronary artery disease. In this retrospective study, 172 patients with acute coronary syndrome (STEMI, NSTEMI, UA) are included. They had been hospitalized on an emergency basis in the Cardiology Department, Invasive Sector of Prof. Dr. St. Kirkovich Hospital in Stara Zagora, and the Cardiology Hospital -Yambol between January 2009 and February 2010. We found a significant difference in the age at acute coronary syndrome (ACS) occurrence by sex: earlier manifestation was observed in men (p=0.018). The univariant regression analysis showed that elderly age (p=0.005, OR 1.024), glomerular filtration <90 ml/h (p=0.006, OR 0.964), GRACE-score > 140 pt (p<0.001, OR 1.045), HF (Killip class ≥ II) (p=0.002, OR 15.6) and EF<40% (p=0.003, OR 1) were factors for adverse prognosis in the first, fifth and ninth year. Only GRACE-score was an independent predictor of death obtained by multivariate regression analysis in the study (p=0.002, OR 1.052). The factors influencing long-term survival adversely after ACS are age, smoking, chronic kidney disease, previously experienced myocardial infarction, diabetes mellitus, three-vessel coronary disease, and decreased systolic function of the left ventricle, and GRACE > 140 p.

A project for the long-term strategy of Russian break-through into post-industrial society is suggested which is directed at transformation of the hi-tech complex into the leading factor of economic development. The thesis is substantiated that there is an opportunity to realize such a strategy in case Russia shifts towards the mechanism of the monetary base growth generally accepted in developed countries: the Central Bank increases the quantity of "strong" money by means of purchasing state securities and allocates the increment of money in question according to budget priorities. At the same time for the realization of the said strategy it is necessary to partially restore savings lost during the hyperinflation period of 1992-1994 and default of 1998 and to secure development of the bank system as well as an increase of the volume of long-term credits on this base.

The problem of the Russian economy’s growth rates is considered in the article in the context of Russia’s backwardness regarding GDP per capita in comparison with the developed countries. The author stresses the urgency of modernization of the real sector of the economy and the recovery of the country’s human capital. For reaching these goals short- or mid-term programs are not sufficient. Economic policy needs a long-term (15-20 years) strategy, otherwise Russia will be condemned to economic inertia and multiplying structural disproportions.

Neoclassical Growth Theory

Motivated by inter-regional disparities condition that occurs persistently, this study examines the Indonesian economy in the long run in order to know whether it tends to converge or diverge. This convergence is based on the Solow Neoclassical growth theory assuming the existence of diminishing returns to capital so that when the developed countries reach steady state conditions, developing countries will continuously grow up to 'catch-up' with developed countries. Based on regional economics perspective, each region can not be treated as a stand-alone unit,therefore, this study also focuses on the influence of spatial dependency and infrastructure. Economical and political situations of a region will influence policy in that region which will also have an impact to the neighboring regions. The estimation results of spatial cross-regressive model using fixed effect method consistently confirmed that the Indonesian economy in the long term will likely converge with a speed of 8.08 percent per year. Other findings are road infrastructure has a positive effect on economic growth and investment and road infrastructure are spatially showed a positive effect on economic growth. In other words, the investment and infrastructure of a region does not only affect the economic growth of that region but also to the economy of the contiguous regions.

Debt Capital

Objective –The aims to identify the significant factors that influence a company’s decision to use debt capital. Methodology/Technique – This study uses 5 independent variables namely; firm growth (growth rate in total gross assets), asset tangibility (ratio of net fixed assets to total assets), cost of debt (interest before tax / long term debt), profitability (Earnings Before Interest and Taxes (EBIT) / Total Asset), and business risk (standard deviation of EBIT to total assets). The dependent variable in this study, debt capital, is measured by the ratio of long-term debt to total assets. A purposive sampling method is used to select 11 out of 18 textile and garment companies listed on the Indonesian Stock Exchange between 2014 and 2018 that report their annual financial positions. A quantitative method, panel data analysis technique and SPSS tools were also used in this study. Findings – The results show that debt capital is influenced by profitability, while the remaining factors do not influence debt capital. Novelty – This study adds to the existing literature on internal factors, market condition as an external factors, and debt capital in developed countries. The benefit of this study is to explore the potential capabilities of the industry in using its profit to minimize the use of debt as a source of capital to decrease business risk.
