Opis:
The aim of this paper is to outline how a theoretical intersection between systems theory and grounded theory could be articulated. The paper proceeds by marking that the important difference between systems theory and grounded theory is primarily reflected in the distinction between a revision of social theory on the one hand and the generation of theory for the social world on the other. It then explores figures of thought in philosophy that relate closely to aspects of Luhmann’s theory of social systems. An effectual intersection, an operational intersection, an intersection based on the concept of primary redundancy and a global/transcendental intersection between systems theory and grounded theory are proposed. The paper then goes on to briefly outline several methodological consequences of the intersection for a grounded systems methodology. It concludes by discussing the sort of knowledge for the social world that is likely to emerge from this mode of observation.

Opis:
Non-linear dynamics phenomena have become important for various aircraft motions. Manoeuvrability of an aircraft in critical flight regimes involes non-linear aerodynamics and inertial coupling. Dynamical systems theory provides a methodology for studying non-linear systems of ordinary differential equations. Bifurcation theory is a part of that theory which is considering changes in the stability, which lead to qualitatively different responses of the system. These changes are called bifurcations. The mathematical models used in the paper assume a rigid aircraft with movable control surfaces, and "invidual blade" rotorcraft model. Aerodynamic model includes also a region of higher angles-of-attack including deep stall phenomena. In the present paper, the wing-rock oscillations, and helicopter spin(i.e. intensive spiral glide motion) was studies by means of checking the stability characteristics related to unstable equilibria. Numerical simulations were used to verify the predictions. Wing-rock oscillations were studied to observe the chaos phenomenon in post-stall manoeuvres. Unsteady aerodynamics for prediction of the airfoil loads was included, and the ONERA-type stall model was used.
Zastosowanie teorii systemów dynamicznych do badania krytycznych stanów lotu statków powietrznych. Ruch statku powietrznego jest opisywany za pomocą układu silnie nieliniowych równań różniczkowych zwyczajnych. Zlinearyzowanie równania ruchu nie mogą być zastosowane do opisu wielu zagadnień dynamiki lotu. Teoria systemów dynamicznych pozwala na efektywne badania nieliniowych równań różniczkowych. Teoria bifurkacji, będąca częścią teorii systemów dynamicznych, umożliwia badanie zmian stateczności, które ptowadzą do jakościowo różnych odpowiedzi systemu. Założono, że statek powietrzny jest nieodkształcalny. Uwzględniono stopnie swobody ruchomych powierzchni sterowych oraz łopat wirnika nośnego. Przyjęty model aerodynamiczny umożliwia uwzględnienie zjawiska głębokiego przeciągnięcia dynamicznego oraz niestacjonarności opływu(histereza współczynników aerodynamicznych). Za pomocą metodyki teorii systemów dynamicznych rozpatrzono osobliwości niestateczności typu wing-rock i tzw. "korkociągu" śmigłowca. W celu zweryfikowania przewidzianych niestabilności przeprowadzono cyfrową symulację tych ruchów. Zaobserwowano nieregularność rozwiązań charakterystycznych dla ruchów chaotycznych.

Opis:
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.

Opis:
In this review I am starting a discussion on the subject of the notion „holism”, which was brought by the European Academy of Teachers of Family Medicine into the definition of a family doctor. This notion characterizes one of six axial skills of a family doctor. The holism is known in medical science mainly in field for the human physiology and it shows that a human organism as a whole is something more than just the sum of one’s parts. Feedbacks between the gigantic number of molecules are creating new in terms of quality correctness which may act in complicated and unpredictable way. Other disciplines like psychology and sociology adapted the holism to theories explaining public behaviors. The „holism” is waking big controversies up because of its negative associations with alternative and complementary medicine, with New Age moves and the shamanism. In the new medical discipline – value of the communication with the patient is being underlined in family medicine but medical consultation still has a central meaning. Theories of the chaos and complexities can explain a lot of phenomena in this context, which have the influence of functioning of the entire system of the health care. Correct understanding new medicine notions can prevent appropriating these notions for the needs of charismatic healers.

Opis:
Complex Dynamic Systems Theory (CDST), or complexity, is increasingly being used as a theoretical framework in Applied Linguistics. In this article, we present the reflections of researchers in Teaching English to Speakers of Other Languages (TESOL) about how they have made use of complexity in their work. The aim of this article is to take stock of how it is being used in the field, the challenges and benefits it provides, as well as inspiration for future work from this theoretical perspective. In the first part of the article, we present a concise overview of CDST, focusing specifically on three salient features: its holistic lens, its non-linear perspective on causality, and its focus on emergence and self-organisation. We also take stock of how complexity perspectives have been used to inform research in a variety of applied linguistics topics. We then move on to present narratives provided by nine academics who have employed CDST in their work, which we synthesise with a view to showing how the theory has gradually developed in TESOL. Early encounters of the field with CDST were usually serendipitous, but the theory has so far proved to be useful, both on account of its descriptive power and because of its phenomenological validity. A common theme in the narratives of these experiences of complexity researchers is that complexity is associated with a steep learning curve, compounded by terminological opacity, and conceptual challenges. However, their responses also indicate optimism regarding the potential of the theory to inform research in TESOL and applied linguistics more generally.

Opis:
The paper presents a longitudinal study of writing fluency in second language students. The aim was to follow the development of the students’ fluency during a three-year period in which they studied Swedish as a second language. Fifteen Polish university students participated in the study. The analysis shows that fluency develops non-linearly with some peaks in the average developmental curve. Furthermore, we observed both between- and within-individual variability in fluency in text production. The development of fluency is unpredictable and no one subject mirrors in their development the average curve. Individual differences were observed at every step of second language development. The analysis shows that writers who are slow at typing are not automatically less fluent and that subjects who develop more slowly can achieve a high level of fluency in writing. In general, writers who were slower and less fluent at the beginning made the greatest progress in fluency during the three-year period, compared with those who were more skilled with regard to both language and typing, who achieved a certain level of fluency faster than their fellow students.

Opis:
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.

Opis:
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.
