Opis:: This paper provides an empirical analysis of financial performance of movies produced in Poland between 2000 and 2011. To understand the reason for a motion picture’s success in the theatrical channel various factors concerning total domestic box office performance were regressed from the box office results of 207 movies. This study proposes that the success of a movie can be determined by three elements: product attributes, distribution-related variables and information sources. The results show that the production budget, movie type – sequel or adaptation, star power, genre, scope of the movie’s release and audience rating are closely related to box office, influencing it in a positive way. On the other hand, critics’ rating, release date (April, July, August) and strong competitive pressure from other movies have a substantial negative influence on box office. The results suggest that the overall movie quality (product-related variables) has an economically and statistically significant effect on total demand for Polish movies.

Opis:: In this paper systemic problems of Ukrainian banking sector are reviewed and the solutions are offered. The main objective of the study is to examine the relationship between a financial deepening and economic growth in Ukraine by estimating several multiple regression models over the 1993 to 2015 period. A real GDP growth per capita was used as an indicator for the economic growth. The domestic credit to private sector (% of GDP) was used as an index of financial depth. The study concludes that financial deepening causes a slight impact on the economic growth of Ukraine. A low level of impact is an indicator of a limitedness of lending to the real economy. This means that banking sector has not become the real driving force of the economic growth in Ukraine yet. The study suggests a statement that policy makers should design the policies which will encourage lending especially high tech production, small and mid-size business, micro financing to the real economy to promote economic growth and increase employment.

Opis:: An experiment has been performed in four locations in Poland (Radzików, Leszno, Szelejewo and Nieznanice).Fifteen genotypes from three species (tall fescue - Festuca arundinacea, meadow fescue - F. pratensisand red rescue - F. rubra) were measured and observed during two consecutive years. Despite of phenologicalobservations (heading and flowering start dates), biometrical measurements (plant height, leaf dimension,number of generative stems etc.) and physiological trait (chlorophyll contents index) seed yield of singlepanicle, seed yield of plant and seed yield per plot (i.e. 50 plants) were determined.Significant effects of years, locations and genotypes were calculated for mentioned species for almost alltested traits. Multiple linear regression analysis was used to estimate major predictors of seed yield. It resultedin different numbers of predictors for different species. For meadow fescue five, for red fescue – three and fortall fescue – only two statistically significant predictors were selected. For all species leaf width and numberof generative stems were statistically significant and had positive weights. For meadow and red fescue – alsoseed yield from single inflorescence was significant with positive weight. Our results demonstrate that leafwidth together with number of steams and single panicle yield are the most important determinants of plantseed yield in three Festuca species.

Tematy:: public debt

Opis:: Theoretical background: The growth in government borrowing, carried out in connection with the banks’ capitalisation, significantly increased the state budget expenditures aimed at servicing the capitalisation domestic public debt, which reinforces the general tendency regarding the exacerbation of the budget risk in the debt sphere in Ukraine. A weighty debt-creating factor was the budget deficit, which was covered by borrowing. Proceeding ahead of the rate of increase in debt volumes in comparison with gross domestic product (GDP) growth rates under the influence of internal and external destabilising factors contributed to the excess of the debt levels security indicators and increased the insolvency risk of the state. The increase of the obligations share denominated in foreign currency or linked to the exchange rate in the overall debt structure as an important indicator of the financial system’s vulnerability to exchange rate fluctuations creates additional threats to debt sustainability regarding the increasing currency risk and the national currency devaluation.Purpose of the article: The article is focused on studying the dynamics and structure of Ukraine’s public debt, its ratio to GDP, and an empirical analysis of the relationship between public debt (external and domestic) and economic growth in Ukraine.Research methods: To empirically test the relationship between public debt and economic growth in Ukraine over the 1992 to 2018 period, multiple regression models were conducted. A real GDP per capita was used as an indicator for economic growth and the debt-to-GDP ratio was used as an index of public debt. Research hypotheses were the following: H1: The public external debt-to-GDP ratio and GDP per capita have a strong negative and statistically relevant correlation; H2: The public domestic debt-to-GDP ratio and GDP per capita have a strong negative and statistically relevant correlation.Main findings: Examining the dynamics and structure of Ukraine’s public debt by borrowing market (external and domestic), it is concluded that there is no strong negative or positive statistically relevant correlation between the public debt-to-GDP ratio and GDP per capita for Ukraine. The impact of this factor is so insignificant that it encourages further research to verify that low GDP growth rate causes the increase in Ukraine’s public debt.

Opis:: In this study, the concentration of chromite minerals by amine flotation of a chromite tailing (slime) with content 23.84% Cr2O3 from Yeşilova-Burdur (Turkey) was investigated. In experimental studies, firstly, some operating parameters of the rougher flotation observed for a low-grade chromite tailing were investigated. Secondly, multiple linear regression (MLR) analyses were performed to determine the effects of some operating parameters on the performance of the rougher amine flotation. From the experimental results, multiple linear regression equations were developed to predict the recovery and grade of the chromite concentrate, and the regression coefficients between experimental and predicted values were found to be quite good (R2 values of 0.772 and 0.917, respectively). Additionally, it was found that the conditioning time and low pH value using $H_2SO_4$ showed an important effect on the recovery and the grade of the chromite concentrate.

Opis:: The yips are the loss of automated and finely controlled motor behavior in sport, affecting many golfers. Although studies have examined their causes and treatment, the social and psychological factors that contribute to their duration in golfers remain unknown. This study examined whether overcommitment and social support are related to prolonged symptoms of yips. The participants included 54 yips-affected golfers who completed measures to identify those who were overcommitted and explore their experiences with the yips and social support. Although there was a significant relationship between prolonged symptoms of the yips and overcommitment, social support was not related to its duration. The results contribute to the understanding of the prolongation of the yips in golfers and may apply to players in other sports.

Opis:: Indian SMEs are going to play pivotal role in transforming Indian economy and achieving double digit growth rate in near future. Performance of Indian SMEs is vital in making India as a most preferred manufacturing destination worldwide under India’s “Make in India Policy”. Current research was based on Indian automotive SMEs. Indian automotive SMEs must develop significant agile capability in order to remain competitive in highly uncertain global environment. One of the objectives of the research was to find various enablers of agility through literature survey. Thereafter questionnaire administered exploratory factor analysis was performed to extract various factors of agility relevant in Indian automotive SMEs environment. Multiple regression analysis was applied to assess the relative importance of these extracted factors. “Responsiveness” was the most important factor followed by “Ability to reconfigure”, “Ability to collaborate”, and “Competency”. Thereafter fuzzy logic bases algorithm was applied to assess the current level of agility of Indian automotive SMEs. It was found as “Slightly Agile”, which was the deviation from the targeted level of agility. Fuzzy ranking methodology facilitated the identification & criticalities of various barriers to agility, so that necessary measures can be taken to improve the current agility level of Indian automotive SMEs. The current research may helpful in finding; key enablers of agility, assessing the level of agility, and ranking of the various enablers of agility to point out the weak zone of agility so that subsequent corrective action may be taken in any industrial environment similar to India automotive SMEs.

Opis:: Statistical analysis is helpful for better understanding of the processes which take place in agricultural ecosystems. Particular attention should be paid to the processes of crops’ productivity formation under the influence of natural and anthropogenic factors. The goal of our study was to provide new theoretical knowledge about the dependence of vegetable crops’ productivity on water supply and heat income. The study was conducted in the irrigated conditions of the semi-arid cold Steppe zone on the fields of the Institute of Irrigated Agriculture of NAAS, Kherson, Ukraine. We studied the historical data of productivity of three most common in the region vegetable crops: potato, tomato, onion. The crops were cultivated by using the generally accepted in the region agrotechnology. Historical yielding and meteorological data of the period 1990–2016 were used to develop the models of the vegetable crops’ productivity. We used two approaches: development of pair linear models in three categories (“yield – water use”, “yield – sum of the effective air temperatures above 10°C”); development of complex linear regression models taking into account such factors as total water use, and temperature regime during the crops’ vegetation. Pair linear models of the crops’ productivity showed that the highest effect on the yields of potato and onion has the water use index (R² of 0.9350 and 0.9689, respectively), and on the yield of tomato – temperature regime (R² of 0.9573). The results of pair analysis were proved by the multiple regression analysis that revealed the same tendencies in the crop yield formation depending on the studied factors.

Opis:: Energetyczne wykorzystanie odpadów może przynieść wiele korzyści środowiskowych przy dodatnim efekcie finansowym. Głównymi wyzwaniami technologicznymi, związanymi z przeróbką odpadów na paliwo, są: odseparowanie frakcji niepalnych oraz wysoko chlorowanych, rozdrobnienie oraz homogenizacja. Wytworzone paliwo powinno charakteryzować się parametrami spełniającymi kryteria ustanowione przez Europejski Komitet Normalizacyjny (CEN). Technologia energetycznego wykorzystania paliwa typu SRF (Solid Recovered Fuel) determinuje wymogi dotyczące właściwości fizykochemicznych oraz użytkowych paliwa, a tym samym decyduje o wyborze technologii jego przygotowania.
The paper presents the results of the test of wet grinding of coal with use of electromagnetic mill. The tests were carried out in a batch system at different initial grain sizes of raw material, various coal concentrations in the feed and the various milling times. Based on the multiple regression analysis of the obtained data, it can be concluded that the efficiency of coal grinding wit use of electromagnetic mill depends on the residence time of the particles in the mill working chamber and a solid phase concentration in the feed directed to the process.

Opis:: The article deals with the determinants of the process of internationalization among small and medium-sized enterprises in Poland. In particular, Nowiński and Nowara set out to determine the relationship between the intensity of exports and the geographical diversification of exports, on the one hand, and variables such as the experience of companies on foreign markets, their size and the use of niche strategies, on the other. The analysis is based on empirical data obtained through a survey. Research methods used by the authors include non-parametric Spearman correlation analysis, Mann-Whitney U test, and multiple regression analysis. The results obtained show that the level of internationalization is related to factors such as company resources and skills as well as experience gained abroad-including both the experience of a company on export markets and experience brought to the company by international executives. The authors found a significant relationship between imports of intermediate goods and the level of internationalization of enterprises. On the other hand, there is no significant relationship between the level of internationalization and the size of a company, the authors say. Nowiński and Nowara conclude that the intensity of exports depends on factors such as a company’s export experience and the level of global integration in a sector, while the number of foreign markets targeted is less significant. Generally, the analyzed variables better reflect the intensity rather than geographical diversification of exports, the authors say.

Opis:: Celem pracy było określenie zależności pomiędzy plonem nasion osiemnastu genotypów lnu oleistego a wybranymi cechami ilościowymi oraz zbadanie wzajemnych korelacji pomiędzy analizowanymi cechami. Plon nasion wybrano jako cechę odniesienia z uwagi na to, iż ma ona decydujący wpływ na wartość gospodarczą odmian lnu. Oceniano wpływ, jaki na plon nasion wywierają: wysokość roślin, długość techniczna, długość wiechy, średnica łodyg, liczba rozgałęzień wiechy i masa 1000 nasion oraz plon ogólny, plon słomy i zawartość włókna. Do oceny zależności stosowano analizę regresji wielokrotnej. W dwóch latach prowadzenia doświadczenia stwierdzono piętnaście par cech charakteryzujących się istotną statystycznie współzależnością. Analiza funkcji regresji wielokrotnej wykazała natomiast, że na plon nasion w największym stopniu wpływały plon słomy oraz masa 1000 nasion.
The aim of the presented study was to determine the relationship between seed yield of eighteen genotypes of flax and selected quantitative traits and an investigation of correlations between analyzed traits. Seed yield was chosen as the reference trait due to the fact that it has a decisive influence on the economic value of flax varieties. The influence of plant height, technical length, panicle length, stem diameter, number of branches and 1000 seeds weight on the total seed yield was defined. Multiple regression analysis was used to evaluate the relationship. In the two years of the experiment fifteen pairs of traits were characterized by a statistically significant interdependence. Multiple regression analysis showed, however, that the weight of the seeds tested was mostly influenced by the straw yield and weight of 1000 seeds.

Opis:: To reflect the financial situation of households, especially for emergencies, the main purpose of this research is to analyze financial behavior in relation to savings. This research explains the interaction of minimum savings rules and committed forms of saving, which means that the use of personal budgets depends on financial behavior due to insecurity and the financial situation of families. The research is consistent with some empirical findings on financial behavior in relation to savings, which affect the growth or decline of the economy, because the lower the well-being of families the lower the economic growth or vice versa. The validation of the hypotheses was realized through the analysis of field findings, using the econometric model of savings in relation to financial behavior through factor analysis, reliability analysis and multiple regression analysis. The main finding of this research is the lack of financial behavior to save for emergencies. These findings are important in order for households to be aware of financial behavior in relation to savings, because there is no emergency fund to cover their needs.

Opis:: The paper presents the results of the analysis of the extent of damage to building structures subjected to mining impacts in the form of tremors and continuous surface deformation. The two methods which were used included the multiple regression analysis and the Support Vector Machine – SVM, which belongs to the socalled Machine Learning. The study used the database of the design, technical condition and potential causes of damage to 199 non-renovated buildings, up to the age of 20 years, of a traditional brick construction, located in the mining area of Legnica-Głogów Copper District (LGOM). The conducted analysis allowed for the qualitative assessment of the influence of mining impacts on the extent of damage to the studied buildings.
W referacie przedstawiono wyniki analizy zakresu uszkodzeń budynków poddanych oddziaływaniom górniczym w postaci wstrząsów oraz ciągłych deformacji terenu. Posłużono się statystyczną metodą regresji wielorakiej oraz metodą wektorów podpierających (Support Vector Machine – SVM) zaliczaną do tzw. uczenia maszynowego (Machine Learning). W badaniach wykorzystano bazę danych o konstrukcji, stanie technicznym i potencjalnych przyczynach uszkodzeń 199 nieremontowanych budynków w wieku do 20 lat, o tradycyjnej konstrukcji murowanej, usytuowanych na terenie górniczym Legnicko-Głogowskiego Okręgu Miedziowego (LGOM). Przeprowadzona analiza pozwoliła na jakościową ocenę wpływu oddziaływań górniczych na zakres uszkodzeń badanych budynków.
