In the article, the author presents the basic relations between a nation state and a multicultural society. According to the author, the attitude of the nation state and the dominant nation in the state to the phenomenon of cultural diversity of society is a key phenomenon in the theory and practice of multiculturalism. Namely, the nation state is characterized by two strategies defining the attitude to the cultural diversity of society. It is a strategy of cultural homogenization and a pluralistic. The emergence of a pluralistic strategy begins with the occurrence and eventual growth of phenomena and processes referred to as multiculturalism and multicultural society.
Cheerleading is a new sport, practiced in 110 nations; since 2016 enjoys provisional Olympic status. Its leaders claim that it is a “happy” sport, but research on its psychological effects is lacking. In this field-study we examined core-affect, positive-affect, and negative-affect in 65 cheerleaders before, during, after, and one-hour after a cheerleading training. Core-affect was more positive during and immediately after training, but it tapered off one hour following the training when feeling states were still more positive than at baseline. Negative-affect declined linearly from baseline to one-hour following training when it became significantly lower than its previous values. Positive-affect showed quadratic dynamics, in parallel with arousal, being higher during and immediately after training than during baseline, or one-hour after training. These results demonstrate for the first time that cheerleading is a “happy” sport, which apart from the skill-development also yields positive psychological emotions both during and after training.
In the 21th century we can observe a return to Marx, particularly in the circles of New Left. A critical approach to the legacy of Karl Marx implies a readiness to revise or even reject the false or no longer valid propositions of Marx in order to be able to confront his legacy with the current state of contemporary science. Some of his views have already been definitely rejected (particularly the theory of revolution and of the dictatorship of proletariat). But a part of his contribution remains valid: (1) the philosophy of praxis, i.e. a theory oriented toward a social change, and (2) the sociological theory that interprets politics in terms of class interests.
The paper presents modeling and simulation results of the operation of a three-phase fluidized bed bioreactorwith partial recirculation of biomass. The proposed quantitative description of the bioreactor takes into account biomass growth on inert carriers, microorganisms decay and interphase biomass transfer. Stationary characteristics of the bioreactor and local stability of steady-stateswere determined. The influence of microbiological growth kinetics on the multiplicity of steady-states was discussed. The relationship between biofilm growth and boundaries of fluidized bed existence was shown.
Formalization of a set of beliefs expressed in one language consists in translating them into sentences of another language. The characteristic property of a good formalization is that the target language is correctly chosen and the translations precisely reflect the meaning of the original sentences. In the paper a formalization of ontology of situations (given by Professor Bogusław Wolniewicz) is discussed. I argue that this is an example of a perfect solution of the problem.
The article is devoted to the late Zygmunt Bauman (d. January 2017), a scholar who made an enormous impact on world humanities at the turn of the twentieth century. It briefly presents Bauman’s life and a number of the best known concepts from his works. The author first discusses Bauman’s attitude toward Marxist theory and explains his revision of it. He then introduces the main ideas of Bauman work Modernity and the Holocaust. The article ends with a review of Bauman’s reflections on globalisation and a discussion of his thesis concerning the crisis of the nation state.
At the end of August 2012 the Polish Parliament enacted the Act on State Marine Accident Investigation Commission, which regulates its organization and operation. The Act transposed, within its regulation, Directive 2009/18/EC of the European Parliament and of the Council of 23 April 2009 establishing the fundamental principles governing the investigation of accidents in the maritime transport sector and is based on the Code of the International Standards and Recommended Practices for a Safety Investigation into a Marine Casualty or Marine Incident (Casualty Investigation Code), issued by the International Maritime Organization (IMO) together with amendments to the SOLAS Convention. The purpose of the Directive, as well as the Casualty Investigation Code, is to improve maritime safety and the prevention of pollution by ships by facilitating the expeditious holding of safety investigations and proper analysis of marine casualties and incidents in order to determine their causes. The EU Parliament obliged, through the Directive, the EU Member States to ensure that the safety investigations are conducted under the responsibility of an impartial permanent investigative body, endowed with the necessary powers, and by suitably qualified investigators, competent in matters relating to marine casualties and incidents. This impartial permanent investigative body had been named in Poland: Państwowa Komisja Badania Wypadków Morskich [the State Marine accident Investigation Commission] and began its operation in May 2013 upon the appointment, by the Minister of Transport, Construction and Maritime Economy, of the third one of five statutory members of the Commission. Since the beginning of its activity the Commission has initiated 77 safety investigations, prepared and adopted 272 resolutions, published 53 safety reports and issued more than 30 safety recommendations. The establishment and activity of the Commission leads to greater awareness of casualty causation and has a positive impact on the level of maritime safety.
This article investigates the engagement of EU law with the interests represented and pursued by the Member States within the framework of the European Union. In principle, because the interests which the Member States feed into the EU governance machinery are formulated in political processes at the national level, and thus possess paramount political legitimacy, EU law may only interact with those interests when a clear and sufficient mandate has been provided for doing so. Such mandates follow from Treaty provisions or EU legislation. They embody common political agreements among the Member States by which they commit themselves to realising the specific interests they share, as well as achieving related common policy objectives. In practice, however, the boundaries of EU law’s mandate are difficult to determine with precision, and this may weaken the legitimacy of EU law’s interventions. The weaker legitimacy of the law raises particular problems in the law of the Single Market, where the interests pursued by national governments are subjected to filtering, moderation, and even transformation by the Court of Justice.
The paper presents the response of a three-layered annular plate with damaged laminated facings to the loads acting in their planes. The presented problem concerns the analysis of the combination of global plate failure in the form of buckling with the local micro defects, like fibre or matrix cracks, located in the laminas. The plate structure consists of thin laminated, fibre-reinforced composite facings and a thicker foam core. The matrix and fibre cracks of facings laminas can be transversally symmetrically or asymmetrically located in plate structure. Critical static and dynamic stability analyses were carried out solving the problem numerically and analytically. The numerical results show the static and dynamic stability state of the composite plate with different combinations of damages. The final results are compared with those for undamaged structure of the plate and treated as quasi-isotropic ones. The analysed problem makes it possible to evaluate the use of the non-ideal composite plate structure in practical applications.
The stability of positive linear continuous-time and discrete-time systems is analyzed by the use of the decomposition of the state matrices into symmetrical and antisymmetrical parts. It is shown that: 1) The state Metzler matrix of positive continuous-time linear system is Hurwitz if and only if its symmetrical part is Hurwitz; 2) The state matrix of positive linear discrete-time system is Schur if and only if its symmetrical part is Hurwitz. These results are extended to inverse matrices of the state matrices of the positive linear systems.
The analysis of the positivity and stability of linear electrical circuits by the use of state-feedbacks is addressed. Generalized Frobenius matrices are proposed and their properties are investigated. It is shown that if the state matrix of an electrical circuit has generalized Frobenius form then the closed-loop system matrix is not positive and asymptotically stable. Different cases of modification of the positivity and stability of linear electrical circuits by state-feedbacks are discussed and necessary conditions for the existence of solutions to the problem are established.
Electrical circuits with state-feedbacks are addressed. It is shown that by suitable choice of the gain matrices of state-feedbacks it is possible to obtain the closed-loop system matrices with nilpotency indices equal to two and their state variables are linear functions of time. The considerations are illustrated by linear electrical circuits.
The paper presents differences between technical states and technical operation states of haul trucks in the technical operation process. The specification and analysis of operational parameters of technological vehicles used in surface mining is possible only due to more and more frequently used diagnostic – telemetric systems. While a detailed analysis of machines operation data can result in the more effective management of mining plant operations and the mining process itself. The determination of operational state indices and their individual components allows preventive actions to be commenced, resulting in improving the work organization of the entire mine machinery system. Moreover, the future technical state of machines operated in surface mining is strictly related to the current state and also depends on the events that occurred in the extraction system. A set of parameter values of individual state characteristics, which allow the haul trucks technical and operational state to be characterized, is a direct effect of a telemetric – diagnostic system operation.
The paper presents the experimental study of a novel unsteady-statemembrane gas separation approach for recovery of a slow-permeant component in the membrane module with periodical retentate withdrawals. The case study consisted in the separation of binary test mixtures based on the fast-permeant main component (N2O, C2H2) and the slow-permeant impurity (1%vol. of N2) using a radial countercurrent membrane module. The novel semi-batch withdrawal technique was shown to intensify the separation process and provide up to 40% increase in separation efficiency compared to a steady-state operation of the same productivity.
Most philosophers believe that a unified philosophical account of mental and non -mental actions is possible. This article presents two arguments indicating that in fact it is not possible. The first one says that thinking is not an activity. Its formulation, however, is exposed to significant difficulties. The second argument avoids these difficulties and puts forward a different, though sometimes erroneously identified, thesis that mental and non-mental actions differ significantly, and therefore one theory should not be expected to include both phenomena. Acceptance of this result sheds new light on the problems associated with the language of thought and gives promise to a new answer to the question “What is Le Penseur doing?”
This paper presents a set of concepts aiming at the reconstruction of mechanisms of the development of economic space. These concepts are ordered in the way that consecutive concepts add new pieces of knowledge increasing the degree of cognition of the mechanisms of economic space. This set includes among others: shift from one steady-state to the next steady-states, selforganization and the development out of equilibrium, multiple equilibrium, punctuated equilibrium, innovation in the phase transition, pulsative course of development process, emergence of complex spatial systems, development code of the system of regions.
The paper concerns the problem of state assignment for finite state machines (FSM), targeting at PAL-based CPLDs implementations. Presented in the paper approach is dedicated to state encoding of fast automata. The main idea is to determine the number of logic levels of the transition function before the state encoding process, and keep the constraints during the process. The number of implicants of every single transition function must be known while assigning states, so elements of two level minimization based on Primary and Secondary Merging Conditions are implemented in the algorithm. The method is based on code length extraction if necessary. In one of the most basic stages of the logic synthesis of sequential devices, the elements referring to constraints of PAL-based CPLDs are taken into account.
The paper addresses the problem of constrained pole placement in discrete-time linear systems. The design conditions are outlined in terms of linear matrix inequalities for the Dstable ellipse region in the complex Z plain. In addition, it is demonstrated that the D-stable circle region formulation is the special case of by this way formulated and solved pole placement problem. The proposed principle is enhanced for discrete-lime linear systems with polytopic uncertainties.

In the article is taken the issue of condition of pedagogy as a research field and academic discipline. Many critical researchers and analytics arrives at a conclusion that there is a crisis of: school, higher education, upbringing, teacher’s role, educational system etc. Thus, we face common demand of changes, adaptation, reorganization, modernization, emancipation of/for/towards that what is placed within the field of pedagogy. Fundamental questions about the scientific nature and paradigmaticness of pedagogy are being moved to the further plan and giving up place to the questions about: the state of the pedagogy/pedagogics, the quality of problems considered by it and its ability/readiness to solve those problems.
This paper presents a novel strategy of particle filtering for state estimation based on Generalized Gaussian distributions (GGDs). The proposed strategy is implemented with the Gaussian particle pilter (GPF), which has been proved to be a powerful approach for state estimation of nonlinear systems with high accuracy and low computational cost. In our investigations, the distribution which gives the complete statistical characterization of the given data is obtained by exponent parameter estimation for GGDs, which has been solved by many methods. Based on GGDs, an extension of GPF is proposed and the simulation results show that the extension of GPF has higher estimation accuracy and nearly equal computational cost compared with the GPF which is based on Gaussian distribution assumption.
The sound speed and parameters of nonlinearity B/A, C/A in a fluid are expressed in terms of coefficients in the Taylor series expansion of an excess internal energy, in powers of excess pressure and density. That allows to conclude about features of the sound propagation in fluids, the internal energy of which is known as a function of pressure and density. The sound speed and parameters of nonlinearity in the mixture consisting of boiling water and its vapor under different temperatures, are evaluated as functions of mass concentration of the vapor. The relations analogous to that in the Riemann wave in an ideal gas are obtained in a fluid obeying an arbitrary equation of state. An example concerns the van der Waals gases. An excess pressure in the reflected wave, which appears when standard or nonlinear absorption in a fluid takes place, is evaluated in an arbitrary fluid.
