When working with regional data from different countries, issues concerning data comparability need to be solved, including regional comparability. Differing regional unit size is a common issue which influences the results of socio-economic analyses. In this paper, we introduce a strategy to deal with the regional incomparability of administrative data in international research. We propose a methodological approach based on the areal interpolation method, which facilitates the usage of advanced spatial analyses. To illustrate, we analyze spatial patterns of unemployment in seven Central European countries. We use a very detailed spatial (municipal) level to reveal local tendencies. To have comparable units across the whole region, we apply the areal interpolation method, a process of projecting data from source administrative units to the target structure of a grid. After choosing the most suitable grid structure and projecting the data onto the grid, we perform a hot spot analysis to show the benefits of the grid structure for socio-economic analyses. The proposed approach has great potential in international research for its methodological correctness and the ability to interpret results.

Subject. This article considers the issues of provision of supplementary education services for children and methodological tools for the formation of educational environment. Objectives. The article aims to assess the level of development of the system of supplementary education of children in Krasnoyarsk and offer a methodological approach to improving the management decision-making procedure in the formation of a portfolio of supplementary education services at the municipal level. Methods. For the study, we used the methods of theoretical, empirical, and logistic analyses, and sociological studies. Results. The article offers concrete solutions to the lack of a methodological approach to providing supplementary education services, considering one of the micro-districts of Krasnoyarsk as a case in point. It also offers tools that can be used by public authorities to organize educational space at the municipal level. Conclusions. A unified methodological approach should be used to provide a system of supplementary education, taking into account financial means, as well as differentiation in the distribution of educational facilities throughout the area. The relevance of the set of supplementary education services and consumer preferences should be taken into account, as well.

Hydrate Deposit

Ukraine is an energy-dependent country, with less that 50% of its energy consumption fulfilled by its own resources. Natural gas is of paramount importance, especially for industry and society. Therefore, there is an urgent need to search for alternative and potential energy sources, such as gas hydrate deposits in the Black Sea, which can reduce the consumption of imported gas. It is necessary to refine the process parameters of the dissociation of gas hydrate deposits with a heterogeneous structure. The analyzed known geological–geophysical data devoted to the study of the offshore area and the seabed give grounds to assert the existence of a significant amount of hydrate deposits in the Black Sea. An integrated methodological approach is applied, which consists of the development of algorithms for analytical and laboratory studies of gas volumes obtained during the dissociation of deposits with a heterogeneous structure. These data are used for the computer modelling of the dissociation zone in the Surfer-8.0 software package based on the data interpolation method, which uses three methods for calculating the volumes of modelling bodies. A 3D grid-visualization of the studied part of the gas hydrate deposit has been developed. The dissociation zone parameters of gas hydrate deposits with different shares of rock intercalation, that is, the minimum and maximum diameters, have been determined, and the potentially recoverable gas volumes have been assessed. The effective time of the process of gas hydrate deposit dissociation has been substantiated. The obtained research results of the dissociation process of gas hydrate deposits can be used in the development of new technological schemes for gas recovery from the deep-water Black Sea area.

The goal of the research was to estimate the two-factor production function, which characterizes the relationship between the microenterprise turnover and the employees rate of wages and the flow of investments into the fixed assets. The research examined a production function similar to that of Cobb-Douglas function, without the restrictions on the sum of degrees under factors. The research was based on statistical spatial data; using the information on 82 regions of Russia for 2017. The production function is an effective management tool. The new knowledge obtained is of scientific and practical im-portance. The methodological approach and tools proposed in the article for evaluating the production functions, describing the set of the microenterprises activities in the regions, can be applied in scientific research on the entrepreneurship issues, as well as in justifying the programs of this economy sector devel-opment at the federal and regional levels. The methodology and tools that were used in the research process can be applied in similar studies in the countries with a significant number of territorial (administrative) units. Further research is related to the evaluation of production functions for a set of microenterprises that are specialized in various types of economic activities, as well as those located in municipalities of specific regions.

Spatial Interpolation Method

The spatial distribution of prices is closely linked with the urban real estate market. Property prices are one of the key indicators of economic activity because they influence economic decisions. Decision-makers and consumers often need information about the spatial distribution of prices, but spatial-temporal analyses of the real estate market are based on the prices quoted in different locations across years (epochs). Due to this idiosyncrasy, the resulting datasets are dispersed (different across years) and difficult to compare. For this reason, the existing interpolation methods are not always effective in analyses of the real estate market. A different approach to interpolating real estate prices that supports the generation of continuous interpolated surfaces while maintaining the values of measurement points is thus needed. This paper proposes a method for replacing dispersed spatial data with a regular GRID structure. The GRID structure covers the measured object with a regular network of nodes, which supports uniform interpolation at every point of the analyzed space and a comparison of interpolation models in successive epochs (years). The proposed method was tested on a selected object. The results indicate that the GRID structure can be used in analyses of highly complex real estate markets where input data are incomplete, irregular and dispersed.

This paper aims to investigate innovation capacity mechanisms at a municipal level, through a comparative case study of public sector innovation labs from Boston (US) and Cluj-Napoca (Romania). We employed a qualitative approach, using as a primary tool the OECD framework for assessing the capacity of cities to innovate, and secondarily, a taxonomy of behavioral change strategies. We showed that, despite differences rooted in culture and institutions, innovation labs support the determinants of urban innovation capacity. However, the intensity of their support varies significantly, depending on organizational arrangements and the chosen methodological approach. Accepting this limitation may be an important step in re-configurating innovation labs and in moving towards a clearer agenda on sustainable urban innovation.

First Time

Social inequality has become of great importance nowadays, and it is in metropolitan areas where it appears to be more intense. Thus, inequality becomes unavoidable when rethinking the contemporary cities. To get a grasp of this phenomenon, for the first time in the metropolitan area of Barcelona, a common look between urban morphology and social cohesion is made. The goal is to describe the socio-morphologic structure of the metropolitan territory, which is the result of combining both categorizations and maps of the existing sociological and morphological aspects. For such purpose, a two-stage methodology has been used. The first stage develops the quantitative and qualitative criteria to overlap the two existing maps, and stablishes the areas that will be considered the new socio-morphologic fabrics. The second one applies the areal interpolation method to assign this socioeconomic and/or demographic information to these new fabrics. The result of this combination is a categorization of twenty-one types of fabrics that describes the socio-morphological metropolitan reality. This new categorization sheds light on a tight relationship between urban shape and social cohesion, both conditioning each other. Moreover, the new map shows socio-morphological similarities between distant areas and announces common urban strategies to achieve a larger urban equity. The interest of having this new approach increases when thinking in the new investigation lines that will be derived from there. One of them would be the evolutionary reconstruction, which will allow visualizing processes and ease the understanding of certain phenomena to foresee urban blight.

Random Parameter Logit Model

The overexploitation of groundwater for irrigation purposes is a general problem affecting the management of common resources. The objective of this study was to analyze some of the policy options when facing this issue. A choice experiment was performed in order to elicit farmers' stated preferencesfor four policy instruments, namely i) implementation of a compulsory measurement system of groundwater extraction; ii) improved monitoring of rural areas in order to limit illegal access to groundwater; iii) reforming the groundwater tax system; iv) increasing the supply of reclaimed wastewater for irrigation. A survey was conducted in the Puglia region on a representative sample of 187 farmers, selected in the main hot-spot irrigated areas. A Random Parameter Logit Model was estimated using two covariates (i.e. size of irrigable farmland and farmers' awareness of groundwater shortage). Findings highlighted the farmers' preference for increasing the supply of water for irrigation (i.e. wastewater supply). Among the measures aiming to handle groundwater demand for irrigation, the respondents positively valued the enhancement of rural area monitoring to prevent illegal access, but they rejected a compulsory groundwater metering system. Finally, the methodological approach proved to be an effective tool to improve policy design, making the decisionmaking process more participatory.
