The aim of the paper was to indicate differences in income from agricultural activity earned by farm owners located in different zones under the influence of a big city. The study covered entities from six voivodships: Lower Silesia, Lubelskie, Lesser Poland, Masovia, Pomerania and Greater Poland. The database of the Polish FADN system was the source of data presented in the analysis. The outer and inner metropolitan zone have been distinguished as well as the group of objects located outside metropolitan areas. For the distinguished groups, a comparative analysis was carried out. Research pinpointed that in the inner metropolitan area zone, there was evidently a considerably higher income from a farm on one unit of own work and the estimate rate of wage for an hour of hired work. The average value of these categories was diminishing in subsequent zones along with moving away from the core of metropolitan areas. Apart from that, in all the three researched groups of farms, the average rate of wage of own work was higher than the rate of wage of hired work. This means that farm owners also take wages from management and the incurred economy risk. The height of these wages is subjected to considerable fluctuation that result from e.g., observed economic fluctuations in agriculture.

The aim of the research was to identify the scale of investment activity in commercial farms located within different distances of large urban centres. The research covered six voivodships: Lower Silesia, the Lubelskie Voivodship, Lesser Poland, Masovia, Pomerania and Greater Poland. The source of data used in the analyses was the database of the Polish FADN system. Out of the 3,508 farms participating in the system, over an uninterrupted period between 2004 and 2016, entities operating within the study area were selected and classified into three groups: the inner zone of the metropolitan area, the outer zone of the metropolitan area and others (outside metropolitan areas). Out of the population of 1,668 commercial farms that were selected, 46 operated in the inner zone of metropolitan areas, while 143 – in the outer zone. The averaged values for the distinguished groups were subjected to a comparative analysis. The research showed that farms in metropolitan areas have more factors of production (especially land) and demonstrate faster growth compared to farms located outside the zones of a city’s economic impact. They also spend higher amounts on investment and show a higher investment rate. The scale of investment activity of farms located in metropolitan zones gives such entities a real chance of gaining a competitive advantage (both in resources and production) over farms located outside metropolitan areas.

The aim of the paper is to determine the scale of agricultural land conversion in gmina (municipalities) located in selected metropolitan areas of Poland. Analyses were conducted taking into account the location of agricultural land in relation to the core of metropolitan area and its suitability for agricultural production. The research has shown that in the metropolitan areas selected for analysis, agricultural land conversion in the period 1996–2014 was over twice as fast as the average for Poland, with the most land converted in the core of a metropolitan area, little less in the first zone of gmina around the core, and the least in gmina located on the outskirts of a metropolitan area. The hypothesis saying that the distance of a gmina from the core of the metropolitan area is a significant factor in the differences in conversion processes, and high quality of environmental conditions of agricultural production does not limit (in a significant way) the process of farmland abandonment has been positively verified.

<em>The role of high-speed rail network in the metropolitan areas is becoming more and more important, which has become one of the main ways of the city personnel contacts. This paper mainly uses the social network analysis method to revamp the six national metropolitan areas: metropolitan area of the middle reaches of the Yangtze River, metropolitan area of Hachang, metropolitan area of Chengyu, metropolitan area of Yangtze River Delta, metropolitan area of Zhongyuan, metropolitan area of Beibu Gulf make a comparative analysis. The macroscopic and microscopic angles are used to calculate and compare the overall network characteristics, centrality, core-periphery structure and cohesion subgroups. It is mainly due to the fact that the high-speed rail network structure of the six major metropolitan areas needs to be improved. Metropolitan area of the middle reaches of the Yangtze River and metropolitan area of Zhongyuan are relatively good the integrity and the connectivity. Metropolitan area of Yangtze River Delta is the highest utilization rate of resources. Metropolitan area of Hachang is the highest network density. Metropolitan area of Chengyu is outstanding between core and periphery. Metropolitan area of Beibu Gulf network of organizations is broken. Therefore, when layout of high-speed rail infrastructure, we should consider the high-speed rail network resource utilization, balance high-speed rail traffic within the metropolitan areas, thus enhancing the city’s high-speed rail accessibility and convenience.</em>

Managing the polycentralization of metropolitan areas can contribute to a more even pace of development of builtup areas; it can also increase the economic and temporary accessibility of urban centers. This study, attempts to synthesize the main hypothetical provisions of a comprehensive approach to managing the development of polycentric metropolitan areas in post-socialist countries. It presents the necessity for modeling not only the core city, but also the entire metropolitan area when managing polycentralization. The study reveals the formalized stages of how a polycentric metropolitan area evolves and presents a comprehensive analysis on the main problems of a technological and methodological, administrative and legal nature in managing the development of polycentric metropolitan areas. It also highlights the significance of comprehensively developing the transport infrastructure and the prevalence of information and telecommunication technologies within the metropolitan area, as well as the spatial compactness of the metropolitan areas for the polycentralization progress. It is considered that the specific features of the post-socialist urban process can affect polycentralization, including (post-) suburbanization, reurbanization, and gentrification. Finally, measures are suggested in the field of scientific research and technologies, and municipal and regional management aimed at increasing the manageability of developing polycentric metropolitan areas in a postsocialist urban planning context.

AbstractThe phenomenon of urban brownfields is significant throughout European metropolitan areas. In this chapter, we assess, both in qualitative and quantitative terms, the inherent potential of urban brownfields to provide a relevant and substantial densification strategy for metropolitan areas. First, we explore the various opportunities for improvement of the built environment offered by urban brownfields in terms of environment, society, and economics, which are the core principles of sustainable development. This analysis is, inter alia, a juxtaposition between urban brownfields and the compact and polycentric city model, adapted to the metropolitan area. While brownfield regeneration appears to be a relevant densification strategy, it nevertheless implies that a sufficient reserve of land is available to engage policymakers. Thus, we attempt to estimate the urban brownfield stock in three countries: the United Kingdom, Switzerland, and France. The data subsequently serves as a basis for our calculation of the theoretical construction potential of brownfield sites.

Price Appreciation

We document large long-run differences in average house price appreciation across metropolitan areas over the past 50 years, and show they can be explained by an inelastic supply of land in some unique locations combined with an increasing number of highincome households nationally. The resulting high house prices and price-to-rent ratios in those “superstar” areas crowd out lower income households. The same forces generate a similar pattern among municipalities within a metropolitan area. These facts suggest that disparate local house price and income trends can be driven by aggregate demand, not just changes in local factors such as productivity or amenities.

The objective of the article was to re-define the bipolar metropolitan area within the area of the Kujawsko-Pomorskie region (NUTS 2). Concentration of metropolitan features, as well as socio-economic situations of its communes (NUTS 5) in 2011, and also the dynamics of communes’ development in the period 2009-2011 were considered in the procedure of delimitation. Bydgoszcz and Toruń, as the economically strongest cities in the region, were established as the dual core of the bipolar metropolitan area. It was assumed that the determined metropolitan area would cover the best developed and the fastest developing communes which met the following criteria of a metropolitan area: neighbourhood, continuity, compactness, maximum distance and population. The development levels of the communes were determined with the use of synthetic measure. Its values were calculated considering the economic (e.g. the amount of income) and also social (e.g. unemployment) aspects of regional development, as well as features typical of metropolitan areas, such as: well-developed sectors of R&D, knowledge-based economy and serving superior services. In the research, linear arrangement methods classifying as taxonomic tools of multivariate data analysis was applied. The metropolitan area resulting from the research (BipOM) slightly differs from the Bydgoszcz-Toruń Metropolitan Area (B-TOM) which was formally appointed in 2005 and composed all of the communes located within the area of the Bydgoski and Toruński districts (NUTS 4). Chełmża and Koronowo, as the less developed communes of the districts, were excluded from the new metropolitan area, while the communes of Ciechocinek, Nakło and Unisław, belonging to the neighbouring districts of the region, were included in the BipOM due to their significant level of regional development and its dynamics. Furthermore the Inowrocław district (bordered on the BipOM) was identified as the prospective candidate for the BipOM, due to the fact that its communes demonstrate a high potential for regional development.

Objective Search of pathogenetic mechanisms and risk factors of atherosclerosis in the employees of the cleaning service in Tbilisi. Materials and Methods As a result of a preliminary survey and examination of 200 employes of Tbilisi cleaning service aged 25-45 years (2014-2016), 22 patients with angina, hypercholesterolemia, intimae-media thickness > 0.65 mm, were selected into I group, and 23 individuals without these disorders into II group. In the blood plasma of the selected patients the intensity of oxidative metabolism parameters, TAA and MDA were determined. The variance and correlation analysis (АNOVA) was used for conducting the comparative analysis of the levels of studied parameters. Results In the combined group (I+II) there are several reliable correlations between the Age -TCol, Age-MDA, BMI-Tg, BMI-MDA, LDLChol-HDLChol, LDLChol–TChol, HDLChol-TChol, LDLChol-MDA, LDLChol-TAA. no correlation between these parameters in individual groups (I and II) was found. That indicates that we have an imaginary correlation related to the large intergroup difference between the average values of the group indicators, that is the values of various indicators change during the development of the pathological process, but there is no causal relationship between these alterations. The reliable TAA-MDA correlation in the combined group (I+II) is related to the high anticorrelation between these parameters and the significantly higher average value of TAA in the low-risk group (II) in comparison to the high-risk group (I). Conclusion The results analysis indicates both the diagnostic value of redox status indicators and their leading role in the atherogenesis processes. In populations with a high risk of atherosclerosis, monitoring of serum TAA is recommended.
