A Fed hatása az állampapírkamatra – A Fed-kamatdöntések befolyása a magyar és más feltörekvő piacok államkötvényhozamára

Az olyan jelentős államadóssággal küzdő országok számára, mint a 2000-es években eladósított Magyarország, komoly mozgásteret jelent, ha az adósság kamatain meg tud takarítani. Azonban a kis, nyitott gazdasági státuszból következő világgazdasági függőség az államkötvénypiacon is kiszolgáltatottá teszi a gazdaságpolitikát. Számos területen tapasztalhatjuk, hogy ha az Egyesült Államok „tüsszent”, a feltörekvő gazdaságok „megfáznak”. A többszörösen igazolt feltevést jelen tanulmány a megváltozott világgazdasági környezetben teszteli tizenegy országra – köztük Magyarországra –, nevezetesen azt, hogy a Fed kamata befolyásoló erővel bír a feltörekvő gazdaságok államkötvénykamatára. A nemzetközi kamattranszmisszió fogalomkörébe helyezett regressziós és kauzalitáselemzéssel vizsgáljuk a determináltságot. Azon túl, hogy kimutatjuk a kamattranszmisszió létét, megállapítjuk azt is, hogy különböző földrajzi tér és időhorizont esetén eltérő ez a befolyás, sőt extrém helyzetben meg is szűnhet

Myxoinflammatory fibroblastic sarcoma: investigations by comparative genomic hybridization of two cases and review of the literature

Myxoinflammatory fibroblastic sarcoma (MIFS) is a rare low-grade sarcoma of the distal extremities characterized by a myxohyaline stroma, a dense inflammatory infiltrate and virocyte- and lipoblast-like giant cells. Up to now, only two cases have been investigated cytogenetically, showing complex and heterogeneous karyotypes, in part with supernumerary ring chromosomes. We characterized two further cases of MIFS immunohistochemically and performed comparative genomic hybridization as well as DNA image cytometry analyses. Both tumors showed the characteristic histomorphological pattern of MIFS and were positive for Vimentin and CD68. Moreover, both cases presented aberrant karyotypes including distinct DNA copy number changes involving chromosome 7 and disclosed DNA aneuploid

Overview of motion and presence detection systems used in smart lighting systems

The article describes stages of design of smart lighting systems. Advantages and disadvantages of detectors used in smart lighting systems are stressed with the purpose of further development of these systems. Ambient factors, which affect the detection system, were analyzed and consequent conservation measures were proposed

Transforming Traditions of Material Culture : Spatial and temporal patterns in pottery style, production and use during the second half of the 6th millennium cal BC in south-eastern Transdanubia and beyond

International audienceOne of the most salient traits of a major milestone in European history, the shift to a Neolithic life-style in Central Europe and the associated social changes, was the emergence of pottery production. The main goal of the research project described here is the study of Neolithic pottery production from a complex perspec- tive and the addressing of the associated distinctive social activity types and potential range of meanings during the period from the late Starčevo to the appearance of the Lengyel culture (5500–4900 cal BC). The springboard for our project was the series of intensely investigated sites in southern Transdanubia, a region that acted as a contact zone between the Neolithic communities of Central Europe and the northern Balkans, and thus played a key role in the neolithisation of Central Europe. The research findings from this region are complemented and compared with the data from various sites along the Danube. Aside from our academic colleagues, our research results can be of interest to the broader public too, and our reconstruc- tions of various artefacts and the documentation of our archaeological experiments can be later used as illustrations to museum exhibits. The expected results can be fitted into the broad picture outlined by other research conducted on these sites and offer an exceptionally detailed picture of how the region’s settlements developed during the second half of the 6th millennium BC
