The Settlement System of Poland: Patterns of Change. Poland’s settlement system has become a scene of accelerating metropolitan development over the last few decades. The trends observed and their policy implications are discussed in the article by focusing on sub-spaces, settlement structure components. Special reference is made to the formation of city networks and their role in spatial organization at the national level. A possible future course of the metropolization phenomena, together with some factors of their evolving intensity, is outlined against the background of selected European urbanization scenarios.
The article presents the urban layout, which is a best-preserved example of industrial estates in northern Italy. The subject of the research is a public space of the Crespi d’Adda settlement in the Province of Bergamo in Lombardy. Particular attention is paid to green areas occurring there, and their current use. Program of the public areas was very varied. The main role, besides the factory, held the public park, which is an important compositional and ideological. element of the layout. Research task was to show on example of Crespi, the current situation of former settlements in northern Italy, which are for the author reference material for settlements analyzed in Poland.
Urbanization has a far-reaching impact on the environment, economy, political and social processes. Therefore, understanding the spatial distribution and evolution of human settlements is a key element in planning strategies that ensure the sustainable development of urban and rural settlements. Accordingly, it is very important to map human settlements and to monitor the development of cities and villages. Therefore, the problem of settlements has found its reflection in the creation of global databases of urban areas. Global settlement data have extraordinary value. These data allow us to carry out the quantitative and qualitative analyses as well as to compare the settlement network at a regional, national and global scale. However, the possibility of conducting both spatial and attribute analyses of these data would be even more valuable. The article describes how to prepare raster data so that they can be implemented into a vector database. It answers the questions whether it is possible to combine these data with databases available in Poland and what benefits it brings. It presents the methods of data generalization and the optimization of time and disk space. As a result of the study, two vector databases with GUF data were developed. The first database resolution is similar to the original (~12 m resolution) database, the second database contains less detailed (~20 m resolution) data, generalized using mathematical morphology. Both databases have been enriched with descriptive data obtained from the National Geodetic and Cartographic Resource.
The paper presents the idea of a prosumer energy cloud as a new service dedicated to electricity prosumers. The implementation of the cloud should generate a number of benefits in the following areas: settlements between prosumer and electricity supplier, the development of distributed energy sources in microprocessors and the development of e-mobility. From the prosumer point of view, the proposed idea of a prosumer cloud of energy is dedicated to the virtual storage of energy excess generated in the micro-installation. Physical energy storage in the cloud means recording the volume of electricity introduced into the electricity system from the prosumer’s microprocessors. It is assumed that the energy equivalent to the volume registered in the prosumer cloud can be used at any time at any point in the network infrastructure of the National Power System. Any point of network infrastructure shall be understood as any locally located point of connection of an electricity consumer provided with access authorization. From the point of view of the power grid operators, the idea of a prosumer energy cloud is a conceptual proposition of a service dedicated to the new model of the power system functioning, taking future conditions concerning the significant development of prosumer energy and e-mobility into account. In this concept, electricity would be treated as a commodity only to partial physical storage and above all to trade. In this model a key aspect would be virtual energy storage, that is, the commercial provision by the cloud operator (trading company) of any use of the electricity portfolio by its suppliers. It should be stressed, however, that in the prosumer’s energy cloud functioning, a significant factor would be the cost of guarantees of the use of energy by prosumers at any time and point of connection to the network. This results in the need of taking the presence of certain market risks, both volumetric and cost incurred by clouds operator, which can be minimized by passing a portion of the accumulated volume of generated energy to the cloud operator into account. It should be emphasized that this article presents the first phase of the development of the concept of prosumer energy cloud. However, it is planned to be expanded by the following stages, which include the possibility of controlling and supervising the operation of prosumer installations such as: sources, receivers and physical energy stores, e.g. home energy storage or batteries installed in electric vehicles. Ultimately, it is assumed that the proposed prosumer energy cloud will be outside of the storage of energy (virtual and partly physical) and that aggregation of prosumer resources will create new possibilities for their use to provide a variety of regulatory services, including system ones.
The aim of the study is to examine the importance of economic argumentation in international maritime disputes. The paper first explains what the international maritime disputes, their sources and types are, what principles they are subjected to. It also established what should be understood by economic arguments, emphasizing their relative nature, as well as showing the potential of the Convention on the Law of the Sea of 1982 as a basis for formulating economic argumentation. The importance of economic argumentation was considered in relation to international disputes regarding the legal status of maritime territories, delimitation of maritime zones, power over the sea and use of the sea. Research, carried out, leads to the following conclusions: 1) economic arguments are present in the reasoning of the parties as well as dispute settlement bodies. However, their probative value is limited; 2) in disputes related to the status of maritime features economic reasoning appears in the context of necessity to demonstrate that they can be a basis for delimitation; 3) in delimitation disputes, addressing economic arguments is more complex and contradictory. Economic arguments may be useful in the second phase of delimitation when relevant circumstances are considered. However, the existing practice shows that the range of economic arguments is limited (they cannot serve as a reason for correction of natural inequalities). International jurisprudence denies taking into account arguments based on level of economic development or economic or financial difficulties of a state (except for the catastrophic repercussions for the livelihood and economic wellbeing of the population), the needs of economic development or performance of economic activities (mining, fishing, shipping). An argument associated with assurance of deposit unity is of some importance (when resources are known or readily ascertainable); 4) in disputes concerning the power over the sea some weight is held by an argument associated with the establishment of economic authority, in particular, of a regulatory and control nature; 5) in disputes related to the use of the sea, the importance of economic reasoning is varied. In disputes concerning the prompt release, the role of the economic argument is limited. On the contrary, it is relevant in disputes related to the violation of rights and economic interests of States and people, if they are protected by international law.
