The cognitive aim of this study is to point to the optimum number of local government units and the optimum boundaries of spatial units in Poland with the assumption of minimizing the cumulated theoretical travel time to all settlement units in the country. The methodological aim, in turn, is to present the use of the ArcGIS location-allocation tool for the purposes of delimitation processes as exemplified by administrative boundaries in Poland. The rationale for the implementation of this study is that number and the boundaries of units of all levels of Poland’s current territorial division are far from optimum in the light of minimization of accumulated theoretical travel time to all settlement units in the country. It may be concluded that it would be justifiable to increase the number of voivodships from the current number of 16 to 18. Besides it would be necessary to introduce modifications in relation to units with regional functions. In contrast, the number of districts and communes should be reduced. A continuation of this research may go in the direction of including analysis of public transport network in the research, creating in this way a multimodal set of network data. This would illustrate, apart from the potential itself resulting from the infrastructure, also the actually existing connections.
We propose a class of m-crane control systems, that generalizes two- and three-dimensional crane systems. We prove that each representant of the described class is feedback equivalent to the second order chained form with drift. In consequence, we prove that it is differentially flat. Then we investigate its control properties and derive a control law for tracking control problem.
In the Act on Revitalization of 9 October 2015, for the first time in Poland, the legal act introduced the necessity to apply the principles of universal design (Article 3 paragraph 2 point 3). The practice of investment processes in crisis areas shows that the requirements set out in the Act are not properly implemented. Regeneration processes require attention to improve the quality of life of residents. The article presents issues related to the implementation of universal design principles during revitalization processes. There is a noticeable lack of interest in this issue despite the fact that it is one of the three tasks set before local governments in the Revitalization Act, after social participation and support for people at risk of exclusion in the area of housing. The reasons for this state should be seen in a small knowledge of the issue, deficiencies in the educational process of designers and poor control on the part of local governments and central authorities. This is due to conservation conditions, which often misinterpret the right to protect cultural heritage. The self-government as its own task should guarantee the possibility of using the positive effects of the revitalization process, in particular the implementation of residents’ rights to an independent and dignifi ed life, which is required by the UN Convention on the Rights of Persons with Disabilities.
In the era of an aging society, age friendly cities planning is gaining in importance. Due to the low mobility of these people, it is important to plan their immediate living environment, ensuring access to facilities and areas that meet the basic needs of this special group of urban space users. The paper analyzes the potential accessibility of older people to green areas, sports and recreation facilities, service and commercial facilities, culture and health care facilities, and public transport stops, in order to delimit problem areas characterized by functional and spatial deficits in this area. In addition, the level and quality of accessibility of older people to the abovementioned elements of development.
The state of development, the existing and emerging forms of development, the intensity and legibility of settlement systems, all this is essential for the living conditions of urban residents, their surroundings and peripheral systems. The purpose of the article is to assess the accessibility to market and public services by estimating the distance to these services from housing facilities in Poland. The use of the residential dispersion ratio (RDR) and an analysis of the spatial distribution of municipalities with the highest values of the coefficient allows to identify areas where accessibility to public and market services is weak.
This article discusses the challenges and problems caused by predatory journals in scholarly communication. By focusing on the editorial practices, I describe the case of Dr. Anna Fraud (Anna O. Szust in Polish): a bogus scientist created by four Polish scholars. Dr. Fraud became a member of editorial boards in over 40 scientific journals although she is a fake person and, obviously has no experience in journal editing. The present paper aims to show that scientist always have to care about a quality control and a peer review system. The article concludes with a presentation of the ‘Think. Check. Submit’ Initiative which provides useful and helpful tools for analysing journals by potential contributors.
Scientists around the world agree that nowadays, science is facing severe challenges like poor peer-review system, replicability crisis, or locked science behind paywalls. The National Science Center addresses at least some of them by introducing procedures that promote integrity, ethics, social responsibility, transparency, and openness in science.
The presented article points to the issues of self-consciousness and the possibilities of its development. It defines in this context also concepts of self-evaluation, self-respect, self-appreciation, self-recognition, self-confidence and self-realization. In the text, it is emphasized that self-consciousness is related to the awareness of one´s own psychophysical and social identity - I myself and the world and my place in it. An important means for the development of the healthy self-consciousness is also praise. In the conclusion of the article, attention is paid to the psycho-hygiene as prevention of the failure.
