Research background: The literature overview shows a blank space regarding the effects of ownership on the determination of enterprises' spatial distribution. Various papers identify differences between determinants of the spatial distribution of foreign direct investments, exporters in foreign ownership, and domestically owned exporters; however,...

Size distribution is generally accepted as an important characteristic of business structure, one which impacts on competitiveness, with firm size often regarded as the key determinant of entrepreneurial innovativeness. This article describes the size distribution of enterprises taken from a statistical set of Slovak business entities with a specia...

The US EPA health risk assessment method is currently widely used to assess human health risks for many environmental constituents. It is used for risk assessment from the exposure to various contaminants exceeding tolerable or safe reference doses, determined e.g., for drinking water, soil, air and food. It accepts widely that excess contents of n...

The protective role of hard drinking water against cardiovascular diseases is well documented by numerous studies. This article describes the impact of Ca and Mg contents in the drinking water with different water hardness on the cardiovascular system (arterial stiffness, arterial age) of residents of the Krupina district, the Slovak Republic. The...

Protecting the environment and maintaining the EU's competitiveness must be inextricably linked. From this perspective, the scope of present article may be seen as quite timely. Air pollution is the main environmental risk factor contributing to deterioration of the health of the population, and consequently influences the economic development of t...

The fourth industrial revolution rouses enthusiasm for an increase of wages, especially for highly qualified specialized workers. There is a whole range of questions in regard to the employment and the level of wages of those who will perform routine work. The specialization of the Slovak economy is on a higher level compared to the European Union...

The role of agriculture within the frame of the enlarged EU is analysed in this paper. There is a requirement to perceive the tendency towards the downgrading of the status of agriculture in the national economy of the EU countries with the respect of the differences in the importance of agriculture mainly in the countries that are the new EU membe...

The problem of high unemployment and expected further growth repetitively appears among major global trends, along with the deepening of social instability. This leads to increased inequalities and deepening polarization of wealth as one of the top three global risks. The aim of this paper is to present the results of unemployment and wage developm...

The paper deals with the qualitative characteristics of the housing in the EU countries. On the one hand there is a problem with housing itself and on the other hand there is a problem with the housing quality with its significant impact on the quality of life. The housing quality is defined by the attributes mentioned in the EQLS survey. The exami...

In this paper, we have proved a metrization theorem that gives the sufficient conditions for a uniform IP-loop X to be metrizable by a left-invariant metric. It is shown that by consideration of topological IP-loop dual to X we obtain an analogical theorem for the case of the right-invariant metric.

This study deals with the analysis of relationship between chemical composition of the groundwater/drinking water and the data on mortality from oncological diseases (MOD) in the Slovak Republic. Primary data consist of the Slovak national database of groundwater analyses (20,339 chemical analyses, 34 chemical elements/compounds) and data on MOD (1...

In this paper we investigate the position of agriculture in the economy of EU countries. Agriculture in the EU is highly heterogeneous - we characterise the sector by using the share of agriculture workers of total employment, the share of agriculture in total GDP, and the value added in agriculture per worker. To quantify the economic importance o...

Globalization is a broad concept casually used to describe a variety of phenomena of countries. However, there is no universally accepted definition and neither standard measurement for globalization nor social dimension of globalization. Many attempts have been made to measure globalization. Authors introduce single indices - economic and social g...

In the paper [STEHLIKOVA, B.-MARKECHOVA, D.-TIRPAKOVA, A.: On the existence of a Haar measure in topological IP-loops, Kybernetika (Prague) 47 (2011), 740-754] we have proved that in every locally compact topological IP-loop with topology induced by a left-invariant uniformity there exists at least one regular left Haar measure. In this paper, we p...
