Abstract

The essay critically approaches the current state and directions of changes in the university education. We see the critical point in the unconditioned endorsement by the university of the market values of intense competitiveness of global economy and the cult of the pro-market education which is its inevitable result. We would like to argue that although the university must respect economic conditions and limitations, nevertheless we fear that the ongoing process of corporatization of the university with its management strategies such as cutting costs, scanning environments for competitive purposes, re-engineering highly competitive efficiency criteria for the staff will bring about a neglect of the humanist values rooted in intellectual and social sensibility and hence undermine the social mission of the university which, apart from professional skills and research, must cultivate intellectual pluralism by providing space for intelligent conversation, sharing critical views of the present state of things thus fostering social criticism and the spirit of responsible dissent.

Abstract

This article sheds light on the advent of online platforms and the way it is reshaping urban enviroment, breaking down traditional axes of both social interaction and commercial power, shifting the structure of traditional services. The platform revolution is radically transforming an array of many functional cities’ areas, like transportation, accommodations and personal services. Thus current concerns as strong urbanization, industrialization and world population growth, enable sharing economy firms to flourish as a reaction against the frictions of urban life exploiting such exacerbation, in order to fulfill demand for appropriate services. After a critical analysis of these issues, the article deepens innovative transportation services, moving on to illustrate the Italian rulemaking process as a chance to provide a solution to the ongoing problem of striking the right balance between competing priorities, such as market access and preservation of sustainable mobility. It suggests to reflect upon the best approach able to face the complexity of urban transport systems, in order to break in a new culture for urban mobility, comply to EU legislation too.

Abstract

Drinking fresh water, turning the lights on, travelling by tram, calling our family, or getting a medical treatment are usual activities, but the underlying SCADA (Supervisory Control and Data Acquisition) systems like CIS (Critical Infrastructure Systems), ICS (Industrial Control Systems) or DCS (Distributed Control Systems) were always the target of many types of attacks, endangered the above mentioned simple activities. During the last decades because of the fast spread of the internet based services and the continuous technical development these systems become more vulnerable than ever. Full reconstruction and innovative changes in older SCADA systems has high cost, and it is not always rewarding. Communication protocols as Modbus (1979) serve as a main basis for SCADA systems, so security of Modbus has a major impact of the security of SCADA systems. Our paper raises and answers questions about the security of the Modbus RTU protocol. We focus on the serial Modbus protocol, because in that method we found many unsolved problems, like lack of authentication of the participants, lack of secure channel and so on. The aim of this paper to propose a secure communication alternative for Modbus RTU @ RS485 wire. The main advantage of the proposed method is the coexistence with traditional slaves and bus systems and only software update is necessary

Abstract

Circular economy – a new approach in the understanding of the human–environment relationship. The work presented the assumptions of the circular economy as a new concept of the economy functioning with the method of production “from cradle to cradle” constituting the opposition to the commonly used linear economy approach (take, make, dispose). Work discussed also the impact on the quality of human life and the management of environmental resources. Functional assumptions of the circular economy and its territorial dimension were presented, especially in urban areas where the green economy and sharing economy mechanisms are used. The potential for economic growth and the creation of new jobs was also emphasized due to the implementation of circular economy in the EU countries.

Abstract

The paper presents a review of concepts for the development of city centres in response to social and culture processes, economic, technical and environmental developments taking place at present on those areas. This review proves that concepts tend to change over time from those based on economic dynamics to those based on collaborative commons and on governance. On the example of a few city centres situated in the Silesian Region an analysis was carried out of the concepts being presently applied and with the use of which projects Silesian cities strive to maintain and strengthen the dynamics and vitality of city centres.
