Relacje firm z bankami w Polsce w świetle danych ze sprawozdawczości bankowej

The purpose of the study was to identify factors which influence bank-firm relationships in Poland, herein identified with relationship banking. The results of empirical analysis have demonstrated that Polish firms readily establish single-bank relationships. The results of the econometric model, on two data panels, enabled verification of hypotheses concerning the determinants of relationship banking in Poland from the perspective of characteristics of firms, their crediting banks and macroeconomic environment. On the part of firms, the factors whose influence has been identified include: size, profitability, the manner of financing, investment activity, innovativeness, form of ownership, credit risk and facility size. On the part of the financial sector, the verification covered the influence of competition in the banking sector, competition on the part of the capital market and development of the banking sector. The study also concerned the impact of the business cycle on relationship banking in Poland. The study utilised panel data from different sources: B0300 report (NBP) in years 1997–2010, F-01/I-01 report (Central Statistical Office (GUS)) in years 2005–2010 and other aggregated data (NBP, WSE)

Sand Removal from Sandstone Cliffs as the Main Factor Influencing Properties of Organic Soils – a Case Study of Transitional Bog in the Stołowe Mountains

With this paper we investigate the effect of sand contribution to organic soils and direct influence of this process on the physical and physicochemical properties on the example of transitional bog in the Stołowe Mountains (the Central Sudetes), which was periodically covered by sand material from sandstone cliffs weathering. Field survey and soil sampling were conducted in August 2015 in the area of Białe Skały. Soil material for laboratory analysis was collected from three peat cores, while soil samples were collected from each soil horizon distinguished in each core. Obtained results indicate the great impact of mineral material admixture on soil properties, both physicochemical and chemical. Recorded values of each soil parameter in the organic horizons adjacent to the mineral interlayers differ considerably from those obtained in the soil profile free of sand admixtures. Preliminary study of soil cover of transitional bog will allow correct planning of palaeoecological research about genesis and evolution of this peatland.

Integracja finansowa w Europie po wprowadzeniu euro. Przegląd literatury

The introduction of the euro was one of the most important events in the process of European integration, especially in the financial sector. However, next to its many advantages, the joint currency and single monetary policy increased the probability of property bubbles in the EU low income countries. The excessive speculations, which resulted in the burst of the US property bubble, the financial crisis, as well as the fiscal problems and the recession in Europe in 2010, uncovered the weaknesses of the financial integration and the inability of the European financial system to absorb large shocks. The financial losses, and the risk that some banks and moreover, even some euro zone member countries might become insolvent, underlined the existence of large systemic risks. As a result, cross border lending declined, the European credit market was affected negatively and the uncertainty concerning the stability of the euro increased. The second phase of the crisis in Europe was a starting point to develop some new international solutions to those problems aimed at increasing the stability of the European financial system. Our paper presents an overview of the literature on the advancement of financial integration in the euro zone, as well as in other regions including Poland. The concluding part of this review summarizes also the results of own research of its authors

Low-temperature transport in highly boron-doped nanocrystalline diamond

International audienceWe studied the transport properties of highly boron-doped nanocrystalline diamond thin films at temperatures down to 50 mK. The system undergoes a doping-induced metal-insulator transition with an interplay between intergranular conductance g and intragranular conductance g0, as expected for a granular system. The conduction mechanism in the case of the low-conductivity films close to the metal-insulator transition has a temperature dependence similar to Efros-Shklovskii type of hopping. On the metallic side of the transition, in the normal state, a logarithmic temperature dependence of the conductivity is observed, as expected for a metallic granular system. Metallic samples far away from the transition show similarities to heavily borondoped single-crystal diamond. Close to the transition, the behavior is richer. Global phase coherence leads in both cases to superconductivity also checked by ac susceptibility , but a peak in the low-temperature magnetoresistance measurements occurs for samples close to the transition. Corrections to the conductance according to superconducting fluctuations account for this negative magnetoresistance
