Innovation in Eastern Europe : a case study of Czech Republic

In this study we evaluate innovative performance of the economies of Central and Eastern Europe (CEE) based on the available statistics of innovation processes. We compare such country-level indicators as educational levels, investments in R&D, FDI, trade and licensing flows, patents and scientific articles, and find that the most developed CEE economies are also the most innovative. At the same time, as supported by the results of the interviews in Czech Republic, one of the top performers in the CEE region, its economy is facing a number of challenges that are similar to other middle-income countries around the world. We suggest addressing these challenges from the prospective of the Middle Income Trap, when a middle-income economy to sustain growth must learn to compete with advanced economies in high-skill innovation. Development of effective innovation policy should be a priority for the CEE countries to escape from the middle income trap.

40ar/39ar Dating of alunite from the Pueblo Viejo Gold-Silver District, Dominican Republic

New 40Ar/39Ar ages for alunite from the Moore and Monte Negro deposits in the Pueblo Viejo district, as well as from a newly discovered alunite-bearing zone on Loma la Cuaba west of the known deposits, are reported here. The ages range from about 80 to 40 Ma, with closely adjacent samples exhibiting very different ages. Interpretation of these results in the context of estimated closure temperatures for alunite and the geologic and tectonic evolution of Hispaniola does not lead to a simple conclusion about the age of mineralization. The simplest interpretation, that mineralization was caused by a buried Late Cretaceous (~80 Ma) intrusion, is complicated by lack of intrusions of this age in the area and absence of alteration in overlying limestone. The alternative interpretation, that mineralization was formed during Early Cretaceous (~110 Ma) magmatism and that the 40Ar/39Ar ages were completely reset by Late Cretaceous thrusting, is complicated by a lack of information on the timing and thermal effects of thrusting in central Hispaniola. Alunite studies have yielded similar unclear results in other pre-Cenozoic ore systems, notably those of the Lachlan fold belt in Australia
