Multikulturális szervezet és identitás (Multicultural organisation and identity)

Jelen cikk célja a multikulturális szervezet fogalmának újraértelmezése, amelyet a következő lépések mentén valósít meg: (1) a releváns tudományterületek azonosítása – szervezeti kultúra és munkahelyi diverzitás – és komplementáris jellegük bizonyítása (ki)alakulásuk történeti ívének párhuzamos bemutatása révén, (2) a tudományterületek történeti alakulását hűen megragadni képes, rendszerező elméleti keret kiválasztása és bemutatása, (3) a multikulturális szervezet főbb dimenzióinak azonosítása, valamint (4) a multikulturális szervezeti kontextus meghatározása a fentiekben meghatározott dimenzióknak az elméleti keretben való értelmezése révén. ______ The aim of this article is to redefine the multicultural organizational concept, which is going to be accomplished along the following steps: (1) identifying the relevant disciplines – organizational culture and workplace diversity – and demonstrate their complementary character through a brief review of their roots and development, (2) presenting the organizing theoretical, which helps me to capture the development of the above mentioned literatures (3) identifying the main dimensions of the multicultural organization and (4) defining the multicultural organizational context based on the delineation of the above recognized dimensions within the organizing theoretical frame.

Long-term dynamic patterns and diversity of phytoplankton communities in a large eutrophic river (the case of River Danube, Hungary)

In this paper we present the composition, seasonal dynamics and fluctuations in diversity of the phytoplankton in the Danube River over 24 years. Weekly samplings were conducted at one section of the river at Göd, in the 1669 river kilometer segment. The change in the phytoplankton community structure was analyzed in relation of water temperature and discharge means. Our findings support the opinion that the Danube is very rich in species, although many of the species are rare and could be described only as coloring species. Results indicate trends in the phytoplankton abundance, which are only detectable in long-term studies. By the help of diversity indices we have observed an increase in the phytoplankton community diversity. With the relevant information, an explanation of the significant changes in diversity and richness was formed. Our goals were a construction of a solid database of the phytoplankton, examining the seasonal dynamics of the phytoplankton through a 24 year long study and to see the most important changing factors of the community. The results of this study are to assist and help future model developments to predict the phytoplankton seasonal dynamic patterns.
