The area of numerical analysis interacts with the area of control and systems theory in a number of ways, some of which are widely recognized and some of which are not fully appreciated or understood. This paper will briefly discuss some of these areas of interaction and place the papers in this volume in context.

Complex phenomena such as play, creativity or innovation are familiar, yet difficult to describe in a systematic manner. In this short article I propose six necessary conditions for any comprehensive description of play. Against this background I discuss my systems-theoretic, constructivist and practice-informed approach to play.

Type and effect systems significantly extend type systems and allow one to express general semantic properties and to statically reason about programs execution. They have been widely exploited to specify static analyses, for example to track computational side effects, resource usage and communication in concurrent languages. In this paper we adopt abstract interpretation techniques to express type and effect systems as abstract semantics. We extend the Cousot’s methodology by introducing an abstract domain which (i) is able to express types with annotations, (ii) is reusable in different analyses with few modifications and (iii) is easily implementable. To test our approach we reconstruct two analyses for which the type and effect systems approach were successful.

The authors are tackling the issue of strategic steering ofmodern societies. Strategic processes are social processes, eventuating in a special field between individual and collective actors and the emergent social structures. The analysis must therefore take both micro and macro level into account. Social dimensions of these processes can be explained by the “social becoming” approach to the analysis of social reality. Within this approach strategy is located on the level of agency, between individuality and totality. This is the reason for “path-dependent” nature of strategic processes and of development, implying “choice within constraints” approach. Strategic actors have freedom of strategic choice, but this choice is constrained by the social structures and culture.

In this paper, the problem of state estimation in an asynchronous distributed multi-sensor system is considered. In such a system, the state of an object of interest is estimated by a group of local estimators. Each local estimator, based on a Kalman filter, performs fusion of data from its local sensor and other (local) processors to compute possibly best state estimates. In performing data fusion, however, two important issues need to be addressed: unknown correlation between data in local processors and the problem of asynchronism of local processors. In this paper, a multi-sensor asynchronous estimation algorithm is presented. The problem of unknown correlation is solved by a covariance intersection method. To deal with asynchronous data a continuous-time stochastic object model is introduced. Simulated experiments illustrate the effectiveness of the proposed approach.

In the paper, simplified models of signals are introduced. The set of signals belonging to the class considered is divided into abstract subsets. Every subset of signals has a representative signal of a very simple form. These representative signals are next used as simplified models of signals and they can be applied to very complicated considerations in systems theory and control theory. For example, they are applied to designing high precision, state feedback control systems. In consequence, such systems approximate (for large gain in feedback loop) the inverse operation to the plant P considered. For solving this problem, the sum of differences of state variables of system and state of control signal are taken into consideration. Based on the simplified models of signals the linear combination of the state variables of system and state of control signal (not only sum of difference) can be used. This is important if the gain in the feedback tends to infinity. A scheme of such systems is presented in the paper.

Artykuł stawia tezę że między dostępem do prawa i interesem publicznym istnieje sprzeczność. Twierdzenie to uzasadnia przeprowadzając przegląd wybranych argumentów na rzecz dostępu do prawa I odnosząc się do danych empirycznych. Następnie interpretuje sprzeczność przy użyciu socjologicznej teorii prawa, pozwalającej na wskazanie strukturalnych przyczyn tej sprzeczności. Aby pogodzić dostęp do prawa z interesem publicznym, system prawny musi wytworzyć semantykę pozwalającą na lepsze pojmowanie warunków inkluzji społecznej. W szczególności, system prawny powinien w końcu odrzucić przednowoczesną koncepcję dostępu do prawa, zorientowaną na dobroczynność, być w stanie odnieść się do dostępu do prawa jako całości I podejmować kwestię warunków inkluzji prawnej. Jeśli to się nie stanie, konflikt między obydwiema wartościami będzie się reprodukował. Ujęcie dostępu do prawa zaproponowane przez Cappellettiego et al w latach 70 XX wieku jest dobrym punktem wyjścia, ale jest dalece niewystarczające…

The paper argues that there exists a contradiction between access to justice and public interest. It substantiates this claim by reviewing selected arguments for access to justice and by referring to empirical evidence. The contradiction is then interpreted using a sociological theory of law, which enables establishing the structural reasons for such a clash. In order to reconcile access to justice with the public interest, the legal system must develop the semantics allowing for a better understanding of social inclusion conditions. In particular, the legal system must finally do away with pre-modern charity-oriented concept of access to justice, be able to grasp access to justice in its totality and reflect on conditions of legal inclusion. If it fails to do that, it is doomed to reproduce the conflict. The concept of access to justice developed by Cappelletti and others in the 1970s is a good point of departure here, but it is by far insufficient.

The aims of this article are: 1) to offer a deeper and more theoretically grounded understanding of the dysfunctions of the institutional support system for people with disabilities in Poland; and 2) to propose inspirations for a new, ‚agile’ disability policy. To this end the author applies concepts from Niklas Luhmann’s theory of social systems and its more recent interpretations, as well as ideas from so-called complexity theory. It is shown that the dysfunctions of the institutional system can be interpreted as resulting from the system’s autopoiesis and insensitivity to the complexity of the environment. Yet, as the system/environment relationship is precarious, the system could be motivated to redefine itself and to implement solutions that would make it more responsive to the environment. It is argued that an agile disability policy, based on the assumption that complexity is a crucial environmental feature, could be a solution to this problem.

The aim of this article is to describe the phenomenon of teenage depression in the context of the impact of depression on the functioning of the family system. The first part of the paper shows the understanding of the concept of the family on the basis of the system theory, paying special attention to the family life cycle and the function of symptoms in the family system. The second part of the article presents the etiology, symptoms and specificity of teenage depression. The developmental tasks characteristic for the age of adolescence were also reconstructed. The last part of the article is devoted to the ways in which depressioncan be understood from a systemic and family therapy perspective The possible ways and directions of working with a teenager and his parents are also indicated.

Obserwowany od lat rozwój logistyki zmierza do zbudowania teorii logistyki. Dyskutowana jest jej naukowość. Dla wielu autorów nie ulega wątpliwości, że teoria logistyki powinna być osadzona w teorii systemów. Na tym tle pojawia się jednak wiele sformułowań i określeń odbiegających od uznanych i powszechnie przyjmowanych terminów i definicji. Zamierzeniem autora jest uporządkowanie i usystematyzowanie związków logistyki i systemów. Efektem podsumowującym rozważania jest koncepcja systemu logistycznego.
EN
The development observed for years of the logistics aims at building the theory of the logistics. For her a scientific nature is being discussed. For many authors there is no doubt that the theory of the logistics should be settled in the systems theory. Against this background however many expressions of both expressions running away from recognized and universally accepted dates and the definition appear. Tidying up and systematizing connections of the logistics and systems is planning the author. A conception is an effect recapitulating discussions of logistic system.

Informacje podstawowe Treści zawarte w artykule są efektem realizacji na zamówienie Narodowego Centrum Badań i Rozwoju projektu rozwojowego pt. Autonomiczne platformy nawodne. Przedstawione założenia teoretyczne do szacowania kosztów życia platformy nawodnej są elementem wykonanego studium wykonalności projektu. Wskazanie metod W artykule podjęto próbę wytłumaczenia językiem teorii systemów oraz teorii modelowania problematykę kosztów życia systemu, która zgodnie z teorią zarządzania stanowi często element studium wykonalności wchodzącego w skład dokumentacji inicjacji projektu. Wyniki i wnioski. Obecnie przy realizacji projektów wymagana jest coraz szersza dokumentacja przy ich inicjacji. Nie dotyczy to jedynie projektów rozległych, kosztownych czy uciążliwych dla środowiska, lecz zaczyna dotykać niemal każdego projektu. Aby przekonać potencjalnych inwestorów trzeba mówiąc językiem dla nich zrozumiałym wykazać celowość inwestycji. Teorie systemów, zarządzania projektami, szeroko pojętego modelowania, eksploatacji czy nauki ekonomiczne utworzyły swój własny system pojęciowy i język, nie unikając przy tym redundancji i niejasności. Dlatego warto poprzedzić studium wykonalności krótkim wstępem teoretycznym celem uściślenia pojęć używanych na jego użytek.

This article provides a theoretical conceptualization of the role of public relations in society based on the “organic theory” of public relations and on Luhmann’s systems theory as well as on the concept of trust. In a postmodern, hypercomplex society, we claim that the main role of public relations is to strengthen system interactions through the creation of trust among systems. To enhance, maintain and ensure trust, public relations practitioners must think, not only strategically, but “metastrategically,” beginning with a normative theory of society that is built on the foundation of existing social theory, e.g. Luhmann, but also on contemporary social theory that must be built within a framework of communication technology.

In this paper the author interprets the changing role of mass media in social processes over recent decades. Society’s perception of mass media is also investigated, with a focus on Central and Eastern Europe. The author explores mass media’s position in the societies of the region, asking how these societies interpret media messages. He analyzes the context of people’s reservations about media messages (people’s misgivings, conditioned by social history). One of the key arguments of the paper is that the majority of audiences in the countries concerned have grown more sceptical of mass media messages than have the audiences of Western European countries. According to the author, various social groups consider that the mass media is heavily politicized and that its construction of reality has little in common with their own interpretations.

Na bazie ogólnej teorii systemów oraz jej paradygmatów została przedstawiona koncepcja systemu logistycznego (SL) opartego na jego elementach, między którymi występują relacje (R). Istotnym elementem koncepcji systemu logistycznego stają się procesy w nim realizowane oraz funkcjonowanie procesów w określonych elementach składowych tego pojęcia. Uzupełnieniem przyjętych rozważań staje się ilościowa ocena funkcjonowania pojęcia w postaci (FV) jako pewnego modelu matematycznego.

On the basis of the general theory of systems and its paradigms there has been introducet the concept of the logistic system (SL) based on its elements reciprocally related (R). The important elements of this logistic system comcept are the processes which are realized in it and also the functioning of these processes in the specified constituent elements of this concept. The quantitative evaluation of functioning of the concept as a mathematic model (FV) is the completion of the assumed speculations.

The trouble of proving the effects of participation lies in the mismatch between three aspects of ownership: physical (possession), legal (ownership proper) and psychological (participation). In our interdisciplinary systemic model of ownership, we propose 10 relationships related to ownership/participation from: „A is a part of B” - greatest involvement to „A does not know about B” - the least involvement. „A” and „B” may take different values of: a person, an institution, a community, a group, an object (material, energetic, informational, purchasing). Once formalized we can view the studies in participation from one, system theory point of view, and formulate hypotheses related to many aspects of ownership. A multilevel analysis with multiple measures of both participation and effectiveness from two data sets has supported the proposed model.

This study proposes to apply an automated lexical analysis to the European Security Strategy of 2003, entitled “A Secure Europe in a Better World”, and the European Union Global Strategy of 2016, entitled “Shared Vision, Common Acton: A Stronger Europe”. The findings are not limited to supporting the predominant interpretations of scholars and experts, but aim at exploring the usefulness of text mining techniques in the interpretation of EU documents. Furthermore, the conclusions drawn from the lexical analysis are discussed in the light of complex systems theory, which may be beneficial for the proper understanding of the concept of resilience (mainly its multidimensional nature) and its subsequent operationalization. The last part of the paper includes an in-depth analysis of the EU rhetoric on the UN fora (period: 2014–2019) regarding the concept of resilience, in particular its linkages with human rights.

The presented paper discusses the theoretical safety issues in complex sociotechnical systems. The traditional efforts to deal with the accidents/hazard events identification problem for complex systems seem to be insufficient, because they have tended to neglect or omitted the broader sociotechnical environment. Following this, a brief literature review in the area of sociotechnical systems modelling is provided. This gives the possibility to develop a formal model for hazard events (safety risk events) occurrence in man-machine-environment systems. The detailed analysis is provided for the performance of transportation systems.

Prezentowany artykuł omawia teoretyczne kwestie bezpieczeństwa złożonych systemów antropotechnicznych. Tradycyjne podejścia w celu rozwiązania problemu właściwej identyfikacji zagrożeń wydają się być niewystarczające, ponieważ zwykle zaniedbują lub pomijają szerszy kontekst socjotechniczny otoczenia. W związku z tym krótko przedstawiono przegląd literatury w obszarze modelowania systemów antropotechnicznych. Pozwoliło to na opracowanie formalnego modelu matematycznego dla opisu zagrożeń występujących w układzie: człowiek-maszyna-otoczenie. Szczegółowa analiza została przedstawiona dla systemu transportowego.
