A globális pénzügyi központok világgazdasági szerepének változásai (The changing role of global financial centres in the world economy)

A pénzügyi központok jelentős mértékben hozzájárulhatnak a bankok nemzetköziesedéséhez. A világgazdaság története során már évszázadokkal ezelőtt létrejött a nemzetközi pénzügyi központok többsége, amelyek szerepe és súlya folytonosan változott. A vezető globális pénzügyi központokban általában mindenféle pénzügyi művelet végrehajtható, intenzíven egy helyre koncentrálódnak a pénzügyi-üzleti műveletek és tranzakciók. Az 1990-es évekre még jellemző globális triád – amit New York, London és Tokió alkotott – napjainkra már megszűnt. A globális pénzügyi központok szerepét a 2010-es években London és New York képes betölteni. Kérdéses azonban, hogy az ázsiai térségben globális pénzügyi központtá válhat-e Hong Kong, esetleg Szingapúr. _____ Financial centres significantly contribute to the internationalization of the banks. Most of the international financial centres were founded centuries ago, but their roles and magnitudes have always changed. All kinds of financial operations can be carried out in the leading global financial centres, and a wide scale of financial operations and transactions concentrate in these places. The dominance of the global triad of New York, London and Tokyo of the 1990s, has recently ended. Only two main financial centres, London and New York, can unambiguously fulfil the role of the global financial centres in the 2010s. However, it is questionable whether Hong Kong or Singapore can become global financial centres in the Asian region of the global economy.

Cut mowing and grazing effects with grey cattle on plant species composition in case of Pannon wet grasslands

Examined area can be found at Balaton Uplands National Park (Hungary). 5 sample areas were examined in Badacsonytördemic: 1: 32 hectare under-grazed pasture, 2: 38 hectare overgrazed pasture, 3: 34 hectare hayfield, 4: trampled area, 5: beaten track. Livestock population was 118 in the monitored pastures. Sampling was executed along five 52m long circular transects, within 5cm × 5cm interlocking quadrates. Based on the data we can state that the curve of the drinking area was the highest of speciesarea examinations however weed appeared because of degradation which provided more species. According to species-area examinations overgrazed areas were richer in species then other examined areas. Based on diversity data drinking area considered degraded, while meadow and overgrazed areas was considered as proper state. Diversity of meadow was larger, but dominance of economically useful species was smaller. The amount of less valuable species – Carex hirta – increased.

Composition of zooplankton assemblages along the Zagyva River

The species composition, longitudinal distribution and seasonal dynamics of zooplankton were studied in the Zagyva River, Hungary. A total of 108 taxa was recorded from which 61 were new for the river. Rotatoria was the most abundant group, microcrustaceans were less important, only nauplii and copepodites were represented in similar individual numbers. Frequent species included Anuraeopsis fissa, Pompholyx spp., Keratella cochlearis, Brachionus angularis, Bdelloida sp., Bosmina longirostris. Dominance of cosmopolitan species was observed both in the river and its reservoir, and species characteristic of eutrophic waters were of major importance in the latter. There was a downstream decrease in zooplankton densities, which was explained by modified conditions. The relatively large number of individuals in autumn months, and the characteristic large number of individuals in the upper section contrasted general findings of potamoplankton dynamics. On the basis of the species abundance matrix, three river sections can be distinguished (upper, middle, lower section). Due to waste water discharges - received from the Tarján Stream - we found extremely high number of individuals and the lowest diversity at the sampling site Nagybátony (148 rkm).
