Research on strategic orientations has mainly focused on Western countries, leaving findings an open issue for other contexts, such as transitional economies. In these economies competition is likely to be fluid and new entrants are approaching the market which offers new perspectives on the strategic orientation-context link. However, extant literature on strategic management has mostly studied short term adaption events or single cases, and to more accurately account for the dynamic process of economic transition, strategic research has to focus on how firms co-evolve with the changing environment. Extending previous work, we investigate the process of firms’ co-evolution with their environment over the last two decades of economic transition in Hungary. Results show that there has been a significant increase in perceived market turbulence, technological turbulence and competitive intensity as the Hungarian economy enters the later phase of economic transition. However, firms do not perceive this change in the environment and do not respond to it by allocating more resources on customer and competitor orientation.
THE AKARI FIS CATALOGUE OF YSOS AND EXTRAGALACTIC OBJECTS

The point sources in the Bright Source Catalogue of the \textit{AKARI} Far-Infrared Surveyor (FIS) were classified based on their FIR and mid-IR fluxes and colours into young stellar object (YSO) and extragalactic source types using a Quadratic Discriminant Analysis method (QDA) and Support Vector Machines (SVM). The reliability of the selection of YSO candidates is high, and the number of known YSO candidates were increased significantly, that we demonstrate in the case of the nearby open cluster {IC348}. Our results show that we can separate galactic and extragalactic \textit{AKARI} point sources in the multidimensioal space of FIR fluxes and colours with high reliability, however, differentiating among the extragalactic sub-types needs further information.

Purpose:Based on a previous gene expression study in a mouse model of asthma, we selected 60 candidate genes and investigated their possible roles in human asthma. Methods: In these candidate genes, 90 SNPs were genotyped using MassARRAY technology from 311 asthmatic children and 360 healthy controls of the Hungarian (Caucasian) population. Moreover, gene expression levels were measured by RT PCR in the induced sputum of 13 asthmatics and 10 control individuals. t-tests, chi-square tests, and logistic regression were carried out in order to assess associations of SNP frequency and expression level with asthma. Permutation tests were performed to account for multiple hypothesis testing. Results: The frequency of 4 SNPs in 2 genes differed significantly between asthmatic and control subjects: SNPs rs2240572, rs2240571, rs3735222 in gene SCIN, and rs32588 in gene PPARGC1B. Carriers of the minor alleles had reduced risk of asthma with an odds ratio of 0.64 (0.51-0.80; P=7×10-5) in SCIN and 0.56 (0.42-0.76; P=1.2×10-4) in PPARGC1B. The expression levels of SCIN, PPARGC1B and ITLN1 genes were significantly lower in the sputum of asthmatics. Conclusions: Three potentially novel asthma-associated genes were identified based on mouse experiments and human studies.
