elasticity, housing, residential market, stratification, Bratislava region

The real estate market operates in a highly dynamic environment consisting of competing locations, substantially affecting their morphological, functional and social structure within urban regions. Housing submarkets arise typically on the residential real estate market from the interplay between house unit price segmentation, reflecting varying scale and structure of demand by households, and feedback of supply providing housing units of different size in specific local mixture. The question addressed in this paper is if price variation along the housing cycle, the existing settlement structure, and physical qualities of competing locations systematically influence development of different size-segments. We assume that spatial differentiation exists if significant construction of large units occurs in the most desirable, green and accessible locations. The statistical model is applied in the Bratislava self-governing region. A panel of completed housing unit counts indicates that the price variation accompanying the housing cycle interacts with the settlement structure and environment, indirectly implying an ongoing spatial stratification process.

Landsat 8, spectral index, multiresolution segmentation, hierarchical classification, Western Carpathians, Slovakia

The semi-automated object-based image classification (OBIA) has recently become a key method in land cover mapping. Our study demonstrates this robust procedure using OBIA analysis obtained by LANDSAT 8. The advantages of this classification system include time-efficiency and images of greater detail with the same quality as a manual interpretation. A delineation algorithm was created in the Malé Karpaty Mts. with 93.6% overall accuracy and 0.81 Kappa coefficient. Our process was based on multiresolution segmentation that was created on 4 hierarchical levels, with emphasis placed on the expected segmentation result and classification with the following applied spectral indices: the normalized differenced vegetation index, simple ration index and built-up area extraction index. We delineated 11 dominant land cover classes of the Malé Karpaty Mts. on the 4th hierarchical level of our classification, with emphasis on forest and semi-natural areas. This procedure was concurrently applied to other Western Carpathian ranges with the best overall accuracy determined at 78.4% in the Slanské vrchy Mts., 74.16% in the Tríbeč Mts., and 73.1% in the Považský Inovec Mts.

knowledge-intensive business services, settlement system, specialization, diversity, non-metropolitan regions, metropolitan regions, Czechia

The authors examined the spatial distribution of selected knowledge-intensive business services in the Czechia and its principal location factors. The Czechia was chosen as a representative of small countries with relatively developed transport infrastructure, a strong economic position of the capital city and a significant portion of manufacturing and business R&D employment located in non-metropolitan regions. The authors asked if and to what extent it is possible to explain the localisation of knowledge-intensive business services by the population and economic city size. Correspondingly, other local factors such as the concentration of manufacturing companies, business research and development and foreign direct investment were tested. More specifically, the authors focused on the role of large industrial centres in non-metropolitan regions, their ability to attract knowledge-intensive business services and develop regional innovation systems. Empirical results showed a spatial disparity between spatially dispersed manufacturing, which was overrepresented in non-metro-politan regions, and knowledge-intensive business services, heavily concentrated in the metropolitan regions of the three largest cities in the Czechia with Prague holding an exclusive position.

urban green space, classification system, change detection, city centre, Bratislava, Slovakia

Urban areas are currently facing the consequences of climate change such as floods, droughts, heat waves or increased formation of urban heat islands. To deal with these challenges, growing attention has been paid to the potential role of urban green spaces (UGS). Moreover, green spaces located close to where people live are contributing to restoring mental fatigue, serving as a resource for physical activity, reducing mortality and reducing the stress level. The UGS in Bratislava city has been mapped recently using high resolution Sentinel-2A satellite data. The present study aims to examine the UGS structure in Bratislava city centre in more detail using very high resolution ortophotomaps, as well as identify the UGS changes in the years 2003 to 2013 and reveal the main processes contributing to changes. The area of green spaces decreased by 11 ha during the 10 year period, with the soil sealing being the most important process responsible for 54% of change.

fiscal autonomy, revenue and expenditure, local government,Slovakia 

The main objective of the article is to present the structure of revenue and expenditure of municipalities, its evolution in time and spatial distribution of the different categories of revenues and expenditures at the local level. The problem of fiscal autonomy of local self-government is particularly relevant in relation to the possibilities of consolidation of local self-government, which is characterized by great heterogeneity in terms of size and in terms of opportunities in providing public goods. The dependence of the individual communities to different sources of income in Slovakia is considerably varied. While some municipalities are able to obtain a large amount of money from autonomous taxes and business activities, other municipalities are totally dependent on shared taxes and grants and transfers from the central level. Similarly, in the case of expenditure, some municipalities invest resources to further development of new infrastructure and public services, while many other municipalities facing most of the resources to run their own government.
