Subject and purpose of work: The article presents the results of research into the dynamics of changes in income distribution as measured by means of GDP per capita for the regions Bulgaria and Slovakia using quantitative methods. Materials and methods: The transition matrix was used as a research tool. As some authors note, since most of the research is limited to the assessment and analysis of global trends, this does not allow to distinguish the situation in which regions maintain their relative position from the situations in which the general distribution of income changes slightly while the location of some regions changes significantly. In this case, individual regions may differ considerably in their rate of development even in the periods when no convergence was observed. Results: The approach adopted in this study made it possible to verify the degree of diversification of the economic strength of the regions examined and conduct a comparative analysis of the dynamics of changes in the transition matrices.Conclusions: It was concluded that the regions of Slovakia and Bulgaria are developing at the same pace. Income stability can be observed. It is justifiable to look for and workout modern tools that will enable tracking changes in regional development.
The paper deals with the issue of increasing the potential of the wood-processing sector and increasing its efficiency and competitiveness through the impact of foreign direct investment within the specific conditions of the wood-processing industry in the Slovak Republic. The aim of this paper is the analysis and evaluation of the quantitative and qualitative effects of foreign direct investment in the Slovak Republic and other V4 countries with a specific focus on the wood-processing industry in the Slovak Republic.
Data Envelopment Analysis is one of the quantitative methods in economics used more broadly during last years. This is nonparametric method which allows to make an estimation of the efficiency of the organization without having financial data. Authors decided to use this method for validation of the efficiency of the Polish wholesale markets. The National Development Program of the Wholesale Markets expected that all markets will have the same possibility to be efficient. It seems that the development of wholesale markets is varying. To check this hipotheses authors have chosen as an input: area, building area while as an output have been chosen: sales volume per year in tones, the number of traders and the number of producers.
The paper deals with the practical application of quantitative methods for stochastic method FTA in the production process. Through practical examples of using the above method in the production of asphalt, we will show the inaccuracies occurring in selected equipment.
Subject and purpose of work: The article compares cleaning services markets in Warsaw and Moscow. The productivity of work is the subject of the research, but not in the traditional neoclassical nterpretation, but within the institutional economy. The aim of the article is to show new ways of analyzing work productivity using institutional methodology. Materials and methods: The article uses a conventional method, which is a combination of institutional and neoclassical methodology. It covers sociological research tools and statistical methods of data processing used for quantitative analysis as part of the institutional approach. Results: Similar parameters of human capital indicators were obtained in the employees of both markets. The indicators of opportunism in the representatives of the employees of the Moscow market are much higher, which significantly reduces the quantitative values of the institutional work productivity in Eastern markets. Conclusions: In order to increase institutional work productivity in Eastern European markets (Russia) and to reduce opportunistic behavior of transaction participants, it is necessary to modernize institutional environment in these countries.
Effect of dehelminthization on milk yield and milk composition in dairy cows. The aim of this study was to assess the effectiveness of action of selected antiparasitic preparation on milk productivity of cows and milk composition. In coproscopic analyses the qualitative methods by Willis, Żarnowski and Josztowa were used, as well as the quantitative McMaster method. A preparation containing eprinomectin was used for dehelminthization. The study involved100 females after first lactation, which were divided into 2 groups 50 head each: experimental (D) - dewormed in May 2 weeks before going to pasture, control (K) – not dewormed. From the experimental group 15 animals were selected (D1) which were dewormed 2 days before parturition. Analogous group of cows (K1) was selected from the control group (at the same stage of lactation, but not dewormed). It was proved that eprinomectin has a positive effect on milk yield, fat level and dry matter in milk, whereas the effect of this preparation on protein content was not confirmed. It was found that the most favorable time of deworming cows is perinatal period.
Streszczenie. W niniejszej pracy wyznaczono poziomy zawartości ogólnego PCB oraz najbardziej toksycznych kongenerów non-orto (PCB 77, PCB 126, PCB 169) i mono-orto (PCB 114, PCB 156, PCB 157) w wybranych importowanych konserwach z tuńczyka w sosie własnym. Ilościowe i jakościowe oznaczenie badanych związków wykonano metodą kapilarnej chromatografii gazowej, w aparacie GC MSD HP 6890/5973. W większości asortymentów stwierdzono zawartość kongeneru PCB 169. Obliczone równoważniki toksyczności (TEQ) dla badanych konserw wyniosły 10-200 pg-TEQ/kg m.m. Zawartość ogólnego PCB kształtowała się na poziomie 1,4-11,4 μg·kg-1 m.m.
