The Evolution of the Market of the Hungarian Printing Industry after 1989: The End of a Success Story?
SONoMA: A Service Oriented Network Measurement Architecture
Distributed network measurements are essential to characterize
the structure, dynamics and operational state of the Internet.
Although in the last decades several such systems have been
created, the easy access of these infrastructures and the
orchestration of complex measurements are not solved. We propose
a system architecture that combines the flexibility of mature
network measurement facilities such as PlanetLab or ETOMIC with
the general accessibility and popularity of public services like
Web based bandwidth measurement or traceroute servers. To
realize these requirements we developed a network measurement
platform, called SONoMA, based on Web Services and the basic
principles of SOA, which is a well established paradigm in
distributed business application development. Our approach opens
the door to perform atomic and complex network measurements in
real time, handles heterogeneous measurement devices,
automatically stores the results in a public database and
protects against malicious users as well. Furthermore, SONoMA is
not only a tool for network researchers but it opens the door to
developing novel applications and services requiring real-time
and large scale network measurements
And the first shall be the last
This study analyzes the puzzle of Hungarian economic drifting in a long run perspective. The underlying puzzle for the investigation is why bad policies are invariably popular and good policies unpopular, thus why political and economic rationality never overlap. The first part of the article summarizes in eight points the basic features of the postwar period. Then six lessons are offered, which might be useful for other countries in transition or for students of comparative economics and politics, lessons that can be generalized on the basis of the individual country experience

PNG Voices: Listening to Australia's Closest Neighbour: Papua New Guinean Perspectives on Australia and the World
In 2021, a broad coalition of researchers embarked on an unprecedented endeavour: to ask hundreds of ordinary Papua New Guineans about the strengths and challenges of Papua New Guinea (PNG), their dreams for PNG’s future, and how they see Australia’s relationship with PNG. PNG is Australia’s closest neighbour, and the single largest recipient of Australian development assistance. The two nations share a prehistory, and more recently, a colonial history. But despite this apparent closeness, few Australians today can say that they know how people in PNG feel about their own communities or about Australia, or about the impacts of Australian tax monies in PNG. The present study, PNG Voices, represents the first time, to our knowledge, that an Australian institution has sought the opinions of a wide swathe of PNG citizens about their realities and their perception of Australia. We asked 536 Papua New Guineans, originating in 21 of PNG’s 22 Provinces, to reflect on: the strengths and assets of their communities and of PNG as a whole; the challenges facing their communities and PNG as a whole; their dreams for their communities; Australia and Australians, and Australia’s relationship with PNG; the types of foreign investment in PNG by different actors. In sum, this has been the first major survey of Papua New Guinean attitudes toward PNG and Australia’s role in it. The key findings of PNG Voices do not always make for easy reading. Some readers may find points of dissonance between how some in PNG view Australia and how the Australia-PNG relationship is framed and understood by Australian policymakers. Let those points, along with the detail and subtleties of the responses as a whole, guide renewed reflection on Australia’s relationship with PNG and, perhaps, recalibration of Australian policies with our closest neighbour
Factors for determining dental anxiety in preschool children with severe dental caries
Expression of CDK7, cyclin H and MAT1 is elevated in breast cancer and is prognostic in estrogen receptor- positive breast cancer
Purpose: CDK-activation kinase (CAK) is required for the regulation of the cell-cycle and is a trimeric complex consisting of Cyclin Dependent Kinase 7 (CDK7), Cyclin H and the accessory protein, MAT1. CDK7 also plays a critical role in regulating transcription, primarily by phosphorylating RNA polymerase II, as well as transcription factors such as estrogen receptor-α (ER). Deregulation of cell cycle and transcriptional control are general features of tumor cells, highlighting the potential for the use of CDK7 inhibitors as novel cancer therapeutics. Experimental Design: mRNA and protein expression of CDK7 and its essential co-factors cyclinH and MAT1, were evaluated in breast cancer samples to determine if their levels are altered in cancer. Immunohistochemical staining of >900 breast cancers was used to determine the association with clinicopathological features and patient outcome. Results: We show that expression of CDK7, cyclinH and MAT1 are all closely linked at the mRNA and protein level and their expression is elevated in breast cancer compared with the normal breast tissue. Intriguingly, CDK7 expression was inversely proportional to tumour grade and size and outcome analysis showed an association between CAK levels and better outcome. Moreover, CDK7 expression was positively associated with ER expression and in particular with phosphorylation of ER at serine 118, a site important for ER transcriptional activity. Conclusions: Expression of components of the CAK complex, CDK7, MAT1 and Cyclin H are elevated in breast cancer and correlates with ER. Like ERα , CDK7 expression is inversely proportional to poor prognostic factors and survival
