    Opis:
    A line of argument in the new growth economy discussions is whether specialization or diversification of economic activity on the geographical scale stimulates innovation. This study explores the relation between innovativeness and different types of geographical concentrations in the case of a developing country. The study addresses the discussion through statistical and econometric analyses using variables such as number of patents, new firm entry and exit at the regional level for the period 1995-2001. The results do not confirm that regions with higher levels of related variety or specialization are more innovative, but instead regions with higher levels of variety are found to be more innovative supporting the diversity thesis.

    Opis:
    The population is continuously exposed to a background level of ionizing radiation due to the natural radioactivity and, in particular, with radon (222Rn). Radon gas has been classified as the second leading cause of lung cancer after tobacco smoke [1]. In the confined environment, radon concentration can reach harmful level and vary accordingly to many factors. Since the primary source of radon in dwellings is the subsurface, the risk assessment and reduction cannot disregard the identification of the local geology and the environmental predisposing factors. In this article, we propose a new methodology, based on the computation of the Gini coefficients at different spatial scales, to estimate the spatial correlation and the geographical variability of radon concentrations. This variability can be interpreted as a signature of the different subsurface geological conditions. The Gini coefficient computation is a statistical tool widely used to determine the degree of inhomogeneity of different kinds of distributions. We generated several simulated radon distributions, and the proposed tool has been validated by comparing the variograms based on the semi-variance computation with those ones based on the Gini coefficient. The Gini coefficient variogram is shown to be a good estimator of the inhomogeneity degree of radon concentration. Indeed, it allows to better constrain the critical distance below which the radon geological source can be considered as uniform at least for the investigated length scales of variability; it also better discriminates the fluctuations due to the environmental predisposing factors from those ones due to the random spatially uncorrelated noise.

    Opis:
    As the main purpose of this article, the authors consider the level of soil pollution in the Aksu River basin as a result of anthropogenic impact, in which factors of anthropogenic transformation of soils in different zones play an important role, as well as processes occurring in soils as a result of their impact. This article highlights the research of the main analyses carried out, which showed that the anthropogenic transformation of soils within the surveyed territory is multifactorial and complex. As an assumed result, the validity of which is analyzed in this article, it can be considered that the degree and forms of manifestation of anthropogenic transformation of foothill soils depend on their use, as one criterion of which is considered the use of such soil for arable land, including irrigated arable land, in which the degradation of mountain soils is mainly associated with pasture loads during a certain period. As a research question, it remains to be considered whether this is really the case or whether the present territory is subject to a different anthropological impact.
