Wave Climate in the Gulf of Gdańsk vs. Open Baltic Sea near Lubiatowo, Poland

Różyński G.

Archives of Hydro-Engineering and Environmental Mechanics

2010

Vol. 57, nr 2

167-176

The paper analyses long-term variability in the wave climate near Lubiatowo, ca. 15 km east of Łeba harbor, and in the Gulf of Gdańsk, near the Vistula river mouth. The wave climate was reconstructed for the 1958-2001 period by the German Institute for Coastal Research (GKSS). Using basic statistical tools - empirical mean values of significant wave height, estimation of the number of threshold crossings above a prescribed value of that height and conditional empirical probability density functions of wave approach directions - a comparison of wave height at the two locations was executed. A substantial reduction in wave height inside the Gulf (sheltering effect) was measured. Further, the increased storminess over the winter season was estimated for the open sea location. Finally, the analysis of wave approach direction in the open sea location revealed substantial growth in extreme waves from the western sector. Given the geographic configuration of the Gulf and the combined rise in storminess and evolution in extreme wave direction, it can be inferred that the sheltering effect of the Gulf can vary depending on locations within the Gulf. Identification of sheltering patterns in the Gulf emerges as obvious follow-up research. This study could also prove useful in analyses aiming at integrated management of coastal zones in the Gulf, mainly in the implementation of Coastal Protection Law (Apr. 2003), which postulates maintenance of the 2001 shoreline configuration along the entire Polish coast.

Strategie internacjonalizacji przedsiębiorstw w kontekście zachowań nabywców żywności

Kociszewski M., Szwacka-Mokrzycka J.

Przemysł Spożywczy

2009

T. 63, nr 3

22-25

W artykule zaprezentowano zmiany obserwowane w zachowaniach i postawach konsumenckich w Polsce w kontekście procesów globalizacyjnych i ich wpływ na kształtowanie strategii internacjonalizacji przedsiębiorstw przemysłu spożywczego. Szczególną uwagę poświęcono postawom Polaków wobec produktów krajowych i zagranicznych oraz rozpoznawalności marek producentów zagranicznych na polskim rynku żywnościowym.

The paper presents changes in the behaviour and patterns of consumers in Poland in the context of global processes and the implications on shaping international strategy of food industry enterprises. The special attention is paid to Polish attitudes towards domestic and international products and on problem of recognizing international brands on the Polish food market.
