Medical Information Literacy and the Quality of the Medical Services.

Information Literacy is the library operation which makes the library user able to search, retrieve, evaluate, select and use the information resources. Information Literacy is the capability of critical thinking; it is the basis of the continuing education and self -education of the professionals. This skill is more important for Medical Scientists, as they face the continuing change of their discipline. The paper proves the significance of information literacy for the staff of the hospitals, as prerequisite of the qualitative services and the organisation of hospital libraries too. It uses comparative data of the state of the art of the Greek medical libraries and proposes the important items for the success of that innovative and cost-effective service

On the Complexity of Nash Equilibria in Anonymous Games

We show that the problem of finding an {\epsilon}-approximate Nash equilibrium in an anonymous game with seven pure strategies is complete in PPAD, when the approximation parameter {\epsilon} is exponentially small in the number of players.Comment: full versio

Identification of repeated Alpine (ultra) high-pressure metamorphic events by U-Pb SHRIMP geochronology and REE geochemistry of zircon: the Rhodope zone of Northern Greece

U-Pb sensitive high resolution ion microprobe (SHRIMP) zircon geochronology, combined with REE geochemistry, has been applied in order to gain insight into the complex polymetamorphic history of the (ultra) high pressure [(U)HP] zone of Rhodope. Dating included a paragneiss of Central Rhodope, for which (U)HP conditions have been suggested, an amphibolitized eclogite, as well as a leucosome from a migmatized orthogneiss at the immediate contact to the amphibolitized eclogite, West Rhodope. The youngest detrital zircon cores of the paragneiss yielded ca. 560Ma. This date indicates a maximum age for sedimentation in this part of Central Rhodope. The concentration of detrital core ages of the paragneiss between 670-560Ma and around 2Ga is consistent with a Gondwana provenance of the eroded rocks in this area of Central Rhodope. Metamorphic zircon rims of the same paragneiss yielded a lower intercept 206Pb/238U age of 148.8±2.2Ma. Variable post-148.8Ma Pb-loss in the outermost zircon rims of the paragneiss, in combination with previous K-Ar and SHRIMP-data, suggest that this rock of Central Rhodope underwent an additional Upper Eocene (ca. 40Ma) metamorphic/fluid event. In West Rhodope, the co-magmatic zircon cores of the amphibolitized eclogite yielded a lower intercept 206Pb/238U age of 245.6±3.9Ma, which is interpreted as the time of crystallization of the gabbroic protolith. The metamorphic zircon rims of the same rock gave a lower intercept 206Pb/238U age of 51.0±1.0Ma. REE data on the metamorphic rims of the zircons from both the paragneiss of Central Rhodope and the amphibolitized eclogite of West Rhodope show no Eu anomaly in the chondrite-normalized patterns, indicating that they formed at least under HP conditions. Flat or nearly flat HREE profiles of the same zircons are consistent with the growth of garnet at the time of zircon formation. Low Nb and Ta contents of the zircon rims in the amphibolitized eclogite indicate concurrent growth of rutile. Based on the REE characteristics, the 148.8±2.2Ma age of the garnet-kyanite paragneiss, Central Rhodope and the 51.0±1.0Ma age of the amphibolitized eclogite, West Rhodope are interpreted to reflect the time close to the (U)HP and HP metamorphic peaks, respectively, with a good approximation. The magmatic zircon cores of the leucosome in the migmatized orthogneiss, West Rhodope, gave a lower intercept 206Pb/238U age of 294.3±2.4Ma for the crystallization of the granitoid protolith of the orthogneiss. Two oscillatory zircon rims around the Hercynian cores, yielded ages of 39.7±1.2 and 38.1±0.8Ma (2σ errors), which are interpreted as the time of leucosome formation during migmatization. The zircons in the leucosome do not show the 51 Ma old HP metamorphism identified in the neighboring amphibolitized eclogite, possibly because the two rock types were brought together tectonically after 51Ma. If one takes into account the two previously determined ages of ca. 73Ma for (U)HP metamorphism in East Rhodope, as well as the ca. 42Ma for HP metamorphism in Thermes area, Central Rhodope, four distinct events of (U)HP metamorphism throughout Alpine times can be distinguished: 149, 73, 51 and 42Ma. Thus, it is envisaged that the Rhodope consists of different terranes, which resulted from multiple Alpine subductions and collisions of micro-continents, rather similar to the presently accepted picture in the Central and Western Alps. It is likely that these microcontinents were rifted off from thinned continental margins of Gondwana, between the African and the European plates before the onset of Alpine convergenc

International economic theories and educational reform in Greece (1976-77)

In this article I will try to demonstrate that the rift between Greek political parties concerning problems in educational reform in the period 1976- 77 was created to a great extent by different interpretations of the new international economic theories which were being expounded in the 70’s. During the period of transition from a military regime (1974) to the consolidation of democracy (1981), revolutionary and radical political ideas flourished. The neo-Marxist theory of economics and the theory of dependence had a great influence on Greek political thought. The model of ‘modernization’ had been called into question by the Left political parties. The problem was not the issue of development but the kind of development. This lack of agreement not only set limits to the possibilities of successful educational reform in Greece but also posed new questions about the role of education in economic development. The discussion on development and education will be correlated with the changes that were taking place in economy, due to the fact that throughout history education has always been closely allied with productivity, either directly or indirectly.peer-reviewe
