Opis:
Based on the assessment of contemporary reality, it can be said that one of the most critical functions of a modern state is to provide its citizens with an acceptable level of security – that is to say, to create optimal conditions for protection against hypothetical and real threats, such as potential natural disasters, consequences of civilizational advancements (accidents or man-made disasters), terrorist attacks, wars, and armed conflicts. It should be emphasized that in modern, democratic societies, the right of people (social groups) to be protected from numerous threats results from the legal, ethical, and moral norms in force, which have been developed in civilizational development and are based on historical experience. The research focused on analyzing normative documents (laws and regulations) and selected scientific and popular science literature dedicated to the functioning of the crisis management system and contemporary management. The synthetic conclusions of this analysis constitute the basis for further in-depth research.

Opis:
Despite the growing popularity of discourse theory and critical analysis of interrelations between education and its social, political and cultural contexts, neither the “discursive” nor “linguistic” turn in social sciences are usually thought of as possible foundations for pedagogical practice. The aim of this paper is to review the possible educational applications of two critical discourse theories: Critical Language Awareness and Positive Discourse Analysis. Both of those perspectives aim to go beyond the purely research oriented modes of analysis, towards constructive and positive projects of critical language education. Thus, they may provide us with a foundation for a critically oriented pedagogy of language.

Opis:
An edge of a graph is called dot-critical if its contraction decreases the domination number. A graph is said to be dot-critical if all of its edges are dot-critical. A vertex of a graph is called critical if its deletion decreases the domination number. In A note on the domination dot-critical graphs, Discrete Appl. Math. 157 (2009) 3743-3745, Chen and Shiu constructed for each even integer k ≥ 4 infinitely many k-dot-critical graphs G with no critical vertices and κ(G) = 1. In this paper, we refine their result and construct for integers k ≥ 4 and l ≥ 1 infinitely many k-dot-critical graphs G with no critical vertices, κ(G) = 1 and λ(G) = l. Furthermore, we prove that every 3-dot- critical graph with no critical vertices is 3-connected, and it is best possible.

Opis:
The article is showing some concept of critical infrastructure system’s safety states model. Model construction is basing on popular technical systems’ safety states models, and notions specified in acts of law related to crisis management and other studies concerning it. Implementation of crisis management issues and problems into technical systems’ safety states model, resulted with formulating of critical infrastructure system’s safety states model, illustrating processes concerned with their transitions, related to particular crisis management phases. Then, probabilistic description of critical infrastructure safety states transitions process have been presented, that, if further evolved, can lead to support works connected to critical infrastructure protection.

The paper presents a method of the GBNCIN operation and safety, with considering the climate-weather change process, safety optimization. Basic characteristics of the critical infrastructure operation process related to climateweather change process are shown. Then, optimal transient probabilities of the GBNCIN Operation Process at Operation States Related to Climate-Weather Change Process, and the GBNCIN optimal safety and resilience indicators, are introduced. By defining unconditional multistate safety function of the GBNCIN, and corresponding optimal risk function, the optimal coefficients of the operation process related to the climateweather change impact on the GBNCIN intensities of degradation, have been determined. Finally, optimal sojourn times of the GBNCIN operation process at operation states, related to climate-weather change process and operation strategy, are presented.

Opis:
For natural numbers k and n, where 2 ≤ k ≤ n, the vertices of a graph are labeled using the elements of the k-fold Cartesian product Iₙ × Iₙ × ... × Iₙ. Two particular graph constructions will be given and the graphs so constructed are called generalized matrix graphs. Properties of generalized matrix graphs are determined and their application to completely independent critical cliques is investigated. It is shown that there exists a vertex critical graph which admits a family of k completely independent critical cliques for any k, where k ≥ 2. Some attention is given to this application and its relationship with the double-critical conjecture that the only vertex double-critical graph is the complete graph.

Opis:
The goal of this paper is to research the pedagogical notion of discontinuity in learning, its pedagogical importance and discover the notion of pedagogical subject that is complementary to it. Discontinuity is closely related to the idea of negativity in its existential sense. Discontinuity and negativity in learning are investigated in their various forms and meanings, in order to understand the pedagogical approach to these phaenomena. Our approach is differentiated by approaches based on “school success”, since pedagogical authors such as J.F. Herbart, J. Dewey and A. English see negativity and its pedagogical potential in an existential sense. Based on these insights, we further ask which kind of pedagogical subject can embody discontinuity and negativity in learning. We find that specific ideas of (critical) theory, (dialectical) knowledge and (critical) subject are needed for that. These ideas open often unexplored possibilities for pedagogical theory and practice.

The Critical Management Act creates a legal basis for dealing with critical infrastructure. It contains the following definition: critical infrastructure includes systems and functional objects which are connected with each other, including: buildings, devices, systems, key services for a country and its citizens’ security and other systems and objects which deal with ensuring efficient functioning of public administration bodies as well as institutions and enterprises. At national level, the protection of critical infrastructure is coordinated by the Government Centre for Security. In accordance with the critical management act, which is in effect at present, the legislator defines that critical infrastructure is created by systems and consists of functional objects connected with each other: buildings, devices, systems, key services for a country’s security and its citizens’ security and other objects and services which deal with ensuring efficient functioning of public administration bodies as well as institutions and enterprises The article contains an enumeration of the systems which are included in critical infrastructure.

Opis:
The paper introduces the concept of a critical incident (CI) in the context of foreign language teaching and discusses its importance for teachers` professional development as a factor leading to a teacher´s awareness of his/her classroom. The ability to diagnose critical incidents is seen as an inseparable part of a teacher´s ability to control the teaching context and thus create critical events (CE). This paper also introduces the concept of an appraisal system (Smith and Lazarus 1993 ), understood as one´s evaluation of the relationship between one´s success and failure in respect of past experience and the ability to adapt to an immediate context. In my analysis I will follow Scherer´s (1984) taxonomy of components of appraisal systems such as novelty, the pleasantness of a task and coping potential, among others. This appraisal system is seen as emotionally-driven but it also emphasizes the cognitive dimension and the interaction between affective and cognitive processing. In the empirical part of the paper, the study on CI in teaching EFL is reported on. The main objective of the study was to make in-service teachers of EFL reflect upon their most memorable critical incident (CI) and evaluate it from the affective point of view. The study was also to make the subjects more aware of themselves and their classroom presence. The research instrument used in the project was the Geneva Appraisal Questionnaire -GAQ (Scherer 2001), based on Scherer´s taxonomy.

A b-coloring is a proper coloring of the vertices of a graph such that each color class has a vertex that has neighbors of all other colors. The b-chromatic number of a graph G is the largest k such that G admits a b-coloring with k colors. A graph G is b-critical if the removal of any vertex of G decreases the b-chromatic number. We prove various properties of b-critical trees. In particular, we characterize b-critical trees.

Opis:
After the russian Federation began its aggression against Ukraine in 2022, the Ukrainian critical infrastructure system was attacked with the aim of its complete or partial destruction. In response to these attacks, the Ukrainian authorities announced the reconstruction of the infrastructure protection system based on eU legal solutions. therefore, the article discusses the issues of critical infrastructure, both at the european and Polish level. the provisions of 2007 are in force in the Polish legal system, and the 2008 directive – in the european legal system. however, legal provisions were amended in 2022 and will be implemented into national legal systems in 2024. the aim of the article was to analyze the content of the provisions of legal acts in the field of critical infrastructure in Poland and the eU. the analysis is accompanied by research questions regarding how to define basic concepts and terms in both legal systems and the mutual relations of both systems. the article refers to the document examination method that allows for the analysis of legal acts and comparative analysis. eU Member States have gained a superior position over european bodies, but growing natural and anthropological threats and the process of deepening european political integration have resulted in a gradual change in the way of thinking about critical infrastructure. the position of EU bodies under 2022 directive has been significantly strengthened vis-à-vis member states.
Po rozpoczęciu przez Federację Rosyjską agresji na Ukrainę w 2022 r. zaatakowano ukraiński system infrastruktury krytycznej w celu jego całkowitego lub częściowego zniszczenia. W odpowiedzi na te ataki władze ukraińskie zapowiedziały odbudowę systemu ochrony infrastruktury na podstawie rozwiązań prawnych Unii europejskiej. W artykule omówiono zagadnienia infrastruktury krytycznej, zarówno na płaszczyźnie europejskiej, jak i polskiej. W polskim systemie prawnym obowiązują przepisy z 2007 r., natomiast w europejskim – dyrektywa z 2008 r., niemniej jednak w 2022 r. dokonano zmiany przepisów prawnych, które zostaną implementowane do krajowych systemów prawnych w 2024 r. W tekście jako cel przyjęto dokonanie analizy treści przepisów aktów prawnych w zakresie infrastruktury krytycznej w Polsce oraz w Unii europejskiej. Analizie towarzyszą pytania badawcze dotyczące sposobu definiowania podstawowych pojęć i terminów w obu systemach prawnych oraz wzajemnych relacji obu systemów. Nawiązano do metody badania dokumentów pozwalającej na dokonanie analizy aktów prawnych oraz przeprowadzenie analizy porównawczej. Państwa członkowskie uzyskały pozycję nadrzędną wobec organów europejskich, jednak rosnące zagrożenia naturalne i antropologiczne oraz proces pogłębiania europejskiej integracji politycznej wpłynęły na stopniową zmianę sposobu myślenia o infrastrukturze krytycznej. Pozycja organów Unii europejskiej na podstawie dyrektywy z 2022 r. została zdecydowanie wzmocniona wobec państw członkowskich.
