Abstract

Scientific article deals with the characteristics of positive externalities and identifying positive externalities of road transport. In the analysis are the processed data on economic indicators of the Slovak Republic and data for individual regions of the Slovak Republic. Based on the analysis were selected positive externalities of road transport. At present, there is insufficient attention to the positive externalities of the transportation, and despite the fact that road transport and road infrastructure has undeniable positive impact on social development and economic growth of the country.

Abstract

The paper deals with the analysis of demand for bus transport to examine determinants of demand and practices of high school students based on survey of their transport habits in Žilina Region. Transport habits of students are individual and variable in time. This group of passengers is dependent on public passenger transport services because of their travelling to schools. Significant part of demand for public passenger transport is also formed by this this group of passengers. The knowledge of student's transport habits may help in process of adaptation of offering and quality of transport serviceability what may subsequently stabilize demand for public passenger transport.

Abstract

The article deals with the motor vehicle tax in relation with fiscal decentralization, particularly from 2005 with competence delegated to the self-governing regions in the area of motor vehicle tax. The result of this provision in the field of fiscal decentralization is increasing of differences in the motor vehicle tax burden in self-governing regions of Slovakia. The paper is the result of solving a series of impact studies solved by the authors in this field. Gradually over time from the transfer of competences in setting tax rates on motor vehicles to self-governing regions and usage of the incomes of this tax can realistically assess the development and impact of this element of fiscal decentralization in the Slovak Republic as well as propose a solution of resulting situation. The aim is to eliminate differences in motor vehicle tax burden at regional and interstate level while maintaining the current level of tax revenues of self-governing regions.

Magnetic field of the Western Carpathians (Slovakia): reflections on the structure of the crust

A new digital magnetic map of Slovakia on the scale of 1: 200,000 and 1: 500,000 was compiled at the end of 2008 as the output of database magnetic objects from the whole territory of Slovakia at a scale of 1: 50,000. The variable geological structure of the West Carpathian crust is depicted in the equally variable magnetic field of this region. A sizable number of magnetic anomalies with manifold character have been recognized. The basic anomalies distribution was divided into two groups: anomalies connected with rocks of the pre-Neogene basement and anomalies which originate in Neogene and Quaternary volcanic products. Most of the significant anomalies in the pre-Neogene basement were interpreted, modelled and consequently its geological and tectonic classification was worked out. On the basis of the anomalous field features, the following sources of anomalies have been distinguished: a) known, located on the surface, or at shallow depths verified by boreholes, mainly expressed by simple morphology, b) deep-seated and expressed by complicated morphology, reinterpreted or newly interpreted and also problematic. According to our present knowledge the interpretations are insufficient and remain open for further investigation. The above mentioned sources of magnetic anomalies are classified in terms of tectonic provenience to the main tectonic units.

Abstract

The Štiavnica Stratovolcano in Central Slovakia is the largest volcano in the Neogene to Quaternary Carpathian volcanic arc. A large caldera, an extensive subvolcanic intrusive complex and a resurgent horst with late stage rhyolite volcanites are the most characteristic features. The results of new K-Ar and Rb-Sr isotope dating using more sophisticated methodical approaches have changed our view on the timing of volcanic and intrusive activity. K-Ar dating of groundmass fractions combined with Rb-Sr isochron dating in the cases of possible rejuvenation has provided highly reliable results. The lifespan of the stratovolcano is apparently shorter than assumed earlier. Evolution of the stratovolcano took place in five stages during the Early Badenian to beginning of Early Pannonian time: (1) construction of the extensive andesite stratovolcano during the interval 15.0-13.5 Ma; (2) denudation of the volcano concluded with the initial subsidence of a caldera and the contemporaneous emplacement of a subvolcanic intrusive complex of diorite, granodiorite, granodiorite porphyries and quartz-diorite porphyries during the interval 13.5-12.9 Ma; (3) subsidence of the caldera and its filling by differentiated andesites during the interval 13.1-12.7 Ma - volcanic activity overlapping with the emplacement of the youngest intrusions; (4) renewed explosive and effusive activity of less differentiated andesites during the interval 12.7-12.2 Ma; (5) uplift of the resurgent horst in the central part of the caldera accompanied by rhyolite volcanic/intrusive activity during the interval 12.2-11.4 Ma. Extensive epithermal mineralization was contemporaneous with the uplift of the resurgent horst and rhyolite volcanic activity and continued till 10.7 Ma
