Mobile Arbeit aus sozioräumlicher Perspektive: Co-Working Spaces als Chance für suburbane und ländliche Räume?
Authors: Krasilnikova Nadezda , Levin-Keitel Meike
Published: December 2021

The world of labour is undergoing major changes. With the processes of digitalisation, the possibilities to work flexibly wherever people live or spend their time are increasing. Digitalbased forms of work promote the development of mobile work in a self-determined location (e.g. in a home office or co-working space). Such location-independent forms of work offer new opportunities for further development of rural areas and especially small and medium-sized towns. The strategic (re) linking of living and working is in many respects both an opportunity and a challenge in equal measure: A shift in the centre of people’s lives can strengthen the place of residence in rural areas through increased (also) economic demand, through a mix of uses and a diversified demand for local supply or through a reduction of traffic loads, such as commuting. In this paper, we explore both the socio-spatial preconditions and the effects of this shift from places of work to places of residence in rural areas. The aim is to outline a systematic classification of co-working spaces with regard to sustainable spatial development in order to promote the opportunities of mobile work in different suburban and rural areas.
Syntéza kreativního učení a vzdělávání pro udržitelný rozvoj v České republice
Authors: Henderson Laura , Kuříková Michaela , Kroufek Roman
Published: December 2021

Tento článek pojednává o pedagogickém přístupu Vzdělávání pro budoucnost (VpB) propojujícím dva vzájemně provázané podpůrné modely kompetencí: Klíčové kompetence pro udržitelnost (Rieckmann 2017) a model Kreativní návyky mysli (Lucas, Claxton, & Spencer, 2013). Uvedený přístup se týká některých problémů implementace vzdělávání pro udržitelný rozvoj tím způsobem, kdy žáci sami stanovují svou vizi a svůj závazek k provedení změny. Mezi tyto problémy patří : 1) Ekologické vzdělávání se i nadále vede v duchu scientismu, který neumožňuje studentům pochopit sociální a společenské souvislosti hlavních příčin environmentálních problémů a uvědomit si „možnosti konat“ vlastní jednotlivcům i společnosti; 2) Vzdělávání pro udržitelnost často vychází z transmisivních modelů vzdělávání. Je však třeba přejít k participativním, socio-konstruktivistickým, transformativním modelům; 3) Mnoho z kompetencí, které potřebujeme, abychom dokázali čelit problémům 21. století, se nachází mimo kognitivní oblast, především v oblasti afektivní (UNESCO, 2017); 4) Může být nedostatečné pochopení způsobu, jakým se budoucnost „přihodí“. Článek shrnuje, jak se projekt vztahuje k Akční kompetenci (Jensen & Schnack, 1997) a modelu participace (Lundy, 2007), za účelem vytvoření efektivního přístupu k rozvoji udržitelných kompetencí a rozvoji sebepojetí žáků jako aktérů změny. Popisuje implementaci pilotního projektu VpB ve čtyřech třídách základních škol (1.–9. třída) a pozitivní dopad rozvoje kompetencí u účastníků.
The role of Natura 2000 network in protecting the orchid flora of East Macedonia (NE Greece)
Authors: Tsiftsis Spyros
Published: December 2021

East Macedonia (northeast Greece) is a relatively small part of Greece, where a considerable number of orchid taxa occurs. Some of these orchids can only be found there and this fact makes the specific area of Greece unique. In this study, an up-to date database of orchid records was used to assess the effectiveness of the existing Natura 2000 network. Specifically, the effectiveness of the Natura 2000 network was evaluated by identifying the number of orchids whose distribution is overlapping to a lesser or greater extent with the network, which chorological categories are included/excluded from it, and whether the rare and threatened orchid taxa are adequately distributed within that. Out of the 73 orchid taxa recorded in East Macedonia so far, 14 taxa are exclusively distributed outside the Natura 2000 network. Specifically, the Natura 2000 network is not overlapped with a number of Balkan and Mediterranean orchid taxa, which are only sparsely found in East Macedonia. Moreover, most of the orchid taxa that have been classified in the threat categories of the IUCN are distributed within the Natura 2000 network of East Macedonia, and specifically, some of the most threatened ones are almost exclusively distributed within that network. Consequently, although the Natura 2000 network is not congruent with the distribution of a number of species of southern origin, which are widely distributed elsewhere in Greece, it can conserve important floristic elements of Greece, which are orchid taxa of northern or central European origin.
Pollen viability and incompatibility in indigenous rice bean (Vigna umbellata (Thunb.) Ohwi & Ohashi)
Authors: Pascual Maria Lima D , Ruiz Jerome H , Posas Jimmy A , Niño Marjohn C
Published: December 2021

Pollen viability, germination and compatibility are essential in determining the success of pollination and seed setting of high-valued crops. Rice bean (Vigna umbellata (Thunb.) Ohwi & Ohashi) is an underutilized and unexplored indigenous legume with high potential for commercial production. In this study, pollen quality, viability, germination rate and incompatibility among selected six rice bean (V. umbellata) accessions from Barili, Cebu, Philippines were evaluated to determine the barriers and effective pollination habit for increased productivity while retaining the important traits, including high tolerance in poor soils, superior climatic resilience and resistance to pest and diseases. Results of acetocarmine calorimetric assay showed that rice beans’ (V. umbellata) pollens are highly viable, with accessions VU 004 (56.33 ± 4.91%) and VU 007 (54.34 ± 4.53%) having the optimum viability rate. Brewbaker and Kwack medium treated with 0.2 g.l-1 and 0.3 g.l-1 boric acid (H3BO4) enhanced the germination rate in vitro (11.56 ± 5.53% and 9.47 ± 6.50% respectively). Bud (14.96 ± 1.53%) and post-anthesis pollens (10.28 ± 0.94%) have optimum germination rate in 0.2 g.l-1 boric acid media, while anthesis pollens are suitable in media supplemented with sucrose and boric acid alone (12.20 ± 1.50%) and with 0.1 g.l-1 myo-inositol supplementation (8.49 ± 1.86%). Pollination test revealed that rice bean accessions have high self-compatibility (50.76 + 3.45%) and low cross-compatibility (26.57 + 2.49%). The findings provide an important background in understanding the pollen quality and intraspecific interaction among indigenous rice bean (V. umbellata) accessions in Barili, Cebu to improve production and hybridization.
Latent class analysis for identification of occupational accident casualty profiles in the selected Polish manufacturing sector
Authors: Nowakowska M. , Pajecki M.
Published: December 2021

The objective of the analysis is identifying profiles of occupational accident casualties as regards production companies to provide the necessary knowledge to facilitate the preparation and management of a safe work environment. Qualitative data characterizing employees injured in accidents registered in Polish wood processing plants over a period of 10 years were the subject of the research. The latent class analysis (LCA) method was employed in the investigation. This statistical modelling technique, based on the values of selected indicators (observed variables) divides the data set into separate groups, called latent classes, which enable the definition of patterns. A procedure which supports the decision as regards the number of classes was presented. The procedure considers the quality of the LCA model and the distinguishability of the classes. Moreover, a method of assessing the importance of indicators in the patterns description was proposed. Seven latent classes were obtained and illustrated by the heat map, which enabled the profiles identification. They were labelled as follows: very serious, serious, moderate, minor (three latent classes), slight. Some recommendations were made regarding the circumstances of occupational accidents with the most severe consequences for the casualties.

How Persons with Intellectual Disabilities Are Fighting for Decision-Making Rights
Authors: Finn Chester A. , Smith Matthew S. , Stein Michael Ashley
Published: December 2021

Paternalistic attitudes about what is in the interests of a person with an intellectual disability have long led to abuses, and are embedded in the guardianship laws still in place in most countries. Self-advocates, who identify as people with intellectual or other disabilities and are committed to demanding their rights and educating others about them, are calling for a new approach. They have found support for reforms in the Convention on the Rights of Persons with Disabilities, adopted by the United Nations in 2006 and since acceded to by 182 countries. By supporting the fundamental right of those with disabilities to make decisions, it has enabled disability rights advocates to successfully challenge legal capacity restrictions and push for “supported decision-making.”

Authors: Ang K. M. , Yeap Z. S. , Chow C. E. , Cheng W. , Lim W. H.
Published: December 2021

Different variants of particle swarm optimization (PSO) algorithms were introduced in recent years with various improvements to tackle different types of optimization problems more robustly. However, the conventional initialization scheme tends to generate an initial population with relatively inferior solution due to the random guess mechanism. In this paper, a PSO variant known as modified PSO with chaotic initialization scheme is introduced to solve unconstrained global optimization problems more effectively, by generating a more promising initial population. Experimental studies are conducted to assess and compare the optimization performance of the proposed algorithm with four existing well-establised PSO variants using seven test functions. The proposed algorithm is observed to outperform its competitors in solving the selected test problems.

Human Rights in the Light of the Process of Financialisation
Authors: Nieborak Tomasz
Published: December 2021

The article deals with the challenges resulting from financialisation, in which we observe an increasing impact of the financial sphere in man’s everyday life. It also considers the effect of this process on the functioning of societies and concludes that the process of creating and applying financial market law must be redefined and human rights issues taken into account. In addition to the activity of the UN and the European Union in promoting the concept of business and human rights, the experiences of recent years show that combining human rights with financial market regulation is possible. To achieve this, however, many actors must be involved and a specific understanding of human rights and values must be adopted, and their protection should constitute the core of the legislator’s activity.

Stress calculation method of bending multilayer structural element when bending moment acts in the planes that do not coincident with principal planes
Authors: Kleiza Vytautas , Kleiza Jonas
Published: December 2021

This paper presents stress calculationmethod of bending multilayer structural element when bending moment acts in the planes that do not coincident with principal planes, and cross section is symmetric or asymmetric. Carrying the computation of occurring stress values in multilayer beam layers it is necessary to identify coordinates of cross-section stiffness centre, direction of principal axes, and coordinates of specific points regarding principal axes. Having this information and equation which is valid for stress calculation of bending multilayer beams it is possible to identify normal stress values at any point of the beam cross section under skew bending. It is deduced that stress values and the nature of their changes are influenced by the shape of beam cross-section, its asymmetry degree, and the direction of appliedmoment.

THE GOSPEL OF LUTHER
Authors: Vasileva Svetlana
Published: December 2021

The article deals with the main Reformation ideas of Martin Luther that later influenced the building and formation of the fundamental humanitarian values in Europe and further on in the whole world. The main of them are freedom, justice, autonomy, fairness and responsibility, as well as the value foundations of personal identification, which are closely connected with the problem of free will and choice. They were forged in the process of shaping principles of a new faith by Martin Luther, whereon the new Protestant Church was built with its new ethic dissolving all life spheres of its adepts and building a new type of European rationality. Luther is considered a personality that embodies a significant era in the development of Europe: he did not only demonstrate with his own example what the real faith meant, he set a new direction for the development of society based on the new principles of the Protestant Church. The author of the article analyzes social and geopolitical circumstances under which Luther the Great Reformer lived and formed a new Protestant theology.

Replacement of meat by mycoproteins in cooked sausages: Effects on oxidative stability, texture, and color
Authors: Shahbazpour Narges , Khosravi-Darani Kianoush , Sharifan Anousheh , Hosseini Hedayat
Published: December 2021

Processed meat is one of the most consumed products worldwide. Naturally, production of proteins with animal origins includes limitations such as costs, energy, time, and environmental problems. Thus, replacement of meats by alternative biomaterials such as mycoproteins can be promising. Mycoproteins with hyphal morphologies, including branches and lengths, have close structures to meat and can be a potential alternative for meat products. Therefore, the major objectives of this study included complete replacement of sausage meats by mycoproteins and comparing characteristics of the novel formula with those of meat. In general, physicochemical, microbial, nutritional, and mechanical characteristics of the formulas were assessed. Results showed that the mycoprotein substitution improved the nutritional and health effects due to the higher valuable protein and lower lipid contents. Besides, it had a high content of essential amino acid and unsaturated fatty acid, compared to meat sausage. Absence of yeasts, molds, Salmonella spp., Eshrichia (E.)coli, and Staphiloccocus (S.)aureus verified the effectiveness of the heat treatment and also the effectiveness of the hygienic procedures in both samples. With regard to phycicochemical properties, more contents of moisture and lipids in sausages containing mycoprotein were linked to further water binding capacity (WBC) (P < 0.05) and oil binding capacity (OBC) in them, compared to beef samples. Besides, the mycoprotein sample had lower (P < 0.05) values of carbohydrates, ash, and pH, compared to the beef sample. In contrast, beef sausages had better textural characteristics, such as hardness, cohesiveness, gumminess, and springiness indexes, compared to mycoprotein sausages. Higher water and OBC values of the mycoproteins led to the filling of the protein interstitial spaces as well as decreasing of the textural attributes. Thus, it resulted in the use of less oil and water in mycoprotein formulations. In conclusion, mycoproteins can be addressed as appropriate replacements for meats in sausages.
Three Sarmatian Daggers from the Foot of Toratau Mount
Authors: Nikolaev Sergey
Published: December 2021

Three Sarmatian daggers found during plowing a field at the foot of Toratau Mount in the Southern Urals are published. Their detailed description is given. It is stated that two daggers bear the signs of the early Sarmatian type of bladed weapons. They date back to the 3rd–2nd centuries BC, their discovery confirms the fact of active resettlement by the Sarmatians of the right bank of the Belaya River at this time. The third dagger bears a number of archaic features, has close analogies among random finds in the Prokhorov cemetery and on the left bank of the Belaya River. It dates back to the 4th–3rd centuries BC. It is noted that the left bank of the Belaya River is the main territory of settlement of early nomads in the Southern Urals. The description of the topography of the daggers found in the site is given. It is shown that according to its physical and geographical characteristics, this territory is a closed valley, bounded on all sides by the river, the Turatau and Kushtau Mountains, and gentle ridges running along the Belaya River. It is concluded that in this case, the “valley” version of the settlement of early nomads was implemented, as well as that the settlement of the right bank of the Belaya River occurred, apparently, from its left bank. This territory was a natural periphery of the settlement of nomads in the Southern Urals in the second half-end of the 1st millennium BC.

Published: December 2021

Cadmium (Cd) is a particularly noteworthy metal that may change the secondary metabolism efficacy of pharmaceutical valuable plants. This study aimed to explore the influence of Cd (0, 25, 75, 100, and 150 µM) on the morpho-physiological traits, mineral contents, essential oil composition, and morphology of secretory glands in basil (Ocimum basilicum L.). The exposure to Cd reduced significantly shoot and root dry weight, shoot and root lengths, total chlorophyll, number, and length of secretory gland compared to control plants, while increased peroxidase activity, proline content, and number of stomata. Essential oil compositions were varied in the Cd-treated plants in a dose-dependent manner. The main compounds of the essential oil were Estragole followed by Linalool and Geranial which the highest percentages were observed in the plants treated with Cd 150 µM. The Cd-treated plants exhibited reductions in calcium (Ca) and iron (Fe) concentrations in both leaves and roots. Cd contents in roots and shoots progressively enhanced with increasing Cd concentrations In general, basil showed good tolerance to Cd stress, so that 50% reduction in shoot dry weight occurred in above 100 μm treatments, which can be related to physiological reactions such as increased antioxidant activity, proline content, number of leaves stomata, and changes in other morpho-physiological factors.
Finite element modelling of UHPC under pulsating load using X-ray computed tomography based fiber distributions
Authors: Mellios Nikolaos , Oesch Tyler , Spyridis Panagiotis
Published: December 2021

The benefits of including fibers in ultra-high performance concrete (UHPC) are attributed to their good bond with the matrix and, hence, an optimal utilization of their properties. At the same time, though, fiber reinforcement may contribute to anisotropy in the composite material and induce weak areas. The influence of the fibers’ orientation on the material properties is a matter of current scientific discourse and it is known to play a vital role in structural design. In the case studies presented herein, mechanical laboratory tests using pulsating load regimes on UHPC with a strength of more than 200 MPa were simulated by use of finite element models. The orientations of the fibers were measured for each test sample prior to failure using an X-ray computed tomography (CT) scanner, and these orientations are explicitly implemented into the model. The paper discusses the methodology of merging data retrieved by CT image processing and state-of-the-art FE simulation techniques Moreover, the CT scanning was carried out throughout the testing procedure, which further enables the comparison of the mechanical tests and the FE models in terms of damage propagation and failure patterns. The results indicate that the overall fiber configuration and behavior of the samples can be realistically modelled and validated by the proposed CT-FE coupling, which can enhance the structural analysis and design process of elements produced with steel fiber reinforced and UHPC materials.

Published: December 2021

This study aims to examine the moderating role of the independent status of women directors on the relationship between gender heterogeneity and firm value. The empirical analysis is performed on the panel data of BSE 100 companies for the period of 10 years from the year 2009 to 2018. Generalized Method of Moments is employed along with Fixed Effects Model while controlling for firm and board-specific variables to examine the relationship between gender heterogeneity and firm value. Moderation impact on this relationship is also analyzed empirically as well as graphically. Results show a negative impact of board gender heterogeneity on the value of a firm. Also, there is a negative moderation effect of women independent directors on the relationship between gender heterogeneity and firm value. Empirical findings of the present study contribute to the current discourse of gender heterogeneity and depict the Indian scenario of corporate boards in this context. This is the first study examining the moderating role of women independent directors on the relationship between board gender heterogeneity and the value of a firm in the Indian climate.

ON ASYMPTOTIC RELATIONS FOR THE CRITICAL GALTON – WATSON PROCESS
Authors:   National University of Uzbekistan, Kudratov K.E. , Khusanbaev Y.M. ,   V.I. Romanovskiy Institut of Mathematics
Published: December 2021

Determining the asymptotics of the continuation probability for a Galton–Watson branching process is one of the most important problems in the theory of branching processes. This problem was solved by A.N. Kolmogorov (1938) in the case when the process starts with a single particle, and the classical result is obtained. A similar result for continuous branching processes was proved by B.A. Sevastyanov (1951). The next term in the expansion for continuous branching processes was obtained by V.M. Zolotarev (1957). The next term in the expansion for continuous branching processes in the critical case was obtained by V.P. Chistyakov (1957); the asymptotic expansion in the subcritical case under the condition of finiteness of the k-factorial moment was obtained by R. Mukhamedkhanova (1966). Asymptotic expansions for discrete branching processes in the subcritical and supercritical cases, provided that any m-factorial moment is finite, were obtained by S.V. Nagaev and R. Mukhamedkhanova (1966). In the critical case, the weak convergence of the conditional distribution of the quantity P(Z(n) > 0)Z(n) under the condition Z(n) > 0 to the exponential distribution was proved by A.M. Yaglom (1947) for processes starting with a single particle in the case of finiteness of the third moment of the number of generations. Subsequently, Spitzer, Kesten, and Ney (1966) proved this result under the condition that the second moment is finite. A similar result for branching processes with continuous parameters was established by V.M. Zolotarev (1957). In this paper, we study the asymptotics of the probability of continuation of the critical Galton-Watson process, starting with η particles. In addition, we prove an analogue of Yaglom’s theorem for critical Galton – Watson processes starting with a random number of particles.
ON THE NUMERICAL SOLUTION TO A NON-CLASSICAL PROBLEM OF BENDING AND STABILITY FOR AN ORTHOTROPIC BEAM OF VARIABLE THICKNESS
Authors:   Yerevan State University, Stepanyan S.P.
Published: December 2021

The mathematical model of the problem of bending of an elastically clamped beam is constructed on the basis of the refined theory of orthotropic plates of variable thickness. To solve the problem in the case of simultaneous action of its own weight and compressive axial forces, a system of differential equations with variable coefficients is obtained. The effects of transverse shear and the effect of reducing compressive force of the support are also taken into account. Passing on to dimensionless quantities, the specific problem for a beam of linearly varying thickness is solved by the collocation method. The stability of the beam is discussed.

Slag melt is a current-carrying medium with intense currents induced by gravitational and electromagnetic forces. The remelted electrode rotation leads to a change in hydrodynamic processes proceeding in a slag bath of the ESR installation and associated primarily with the occurrence of a centrifugal force. The flow pattern, which is developed in the slag bath under this force action, is different from that developed at a stationary consumable electrode. A mathematical model is proposed to assess the impact of consumable electrode rotation on hydrodynamics in a slag bath during electroslag melting. A computer program is created to determine the projections of the flow velocities for a liquid flux near a rotating electrode, the moment of its hydraulic resistance, and the renewal time for the slag bath while being stirred. The critical speed of the rotation of the electrode is determined as a function of its diameter at a transitional flow regime for ANF-6 flux. The dependence of the flux flow velocity on the electrode rotation speed is presented. The moment of the rotating electrode resistance in a slag bath is determined at various electrode diameters and various depths of the electrode immersion into the slag. An expression is proposed for estimating the time of the slag bath renewal. It is also shown that at a small depth in the bath due to its intensive mixing under the action of centrifugal forces, the temperature and chemical composition over the slag bath volume during the ESR process can be considered as constant. The ratio of centrifugal and electromagnetic forces is estimated. The results determine a flow pattern of the liquid slag and th

The paper considers the generalized Suslov problem with variable parameters and the influence of random perturbations on the dynamics of the system under consideration. The physical meaning of the Suslov problem is Chaplygin's sleigh, which moves along the inner side of the circle. In the case of a deterministic system, a brief review of the previously obtained results is made, the presence of chaotic dynamics in the system and such effects as the appearance of a strange attractor and noncompact (escaping) trajectories is shown. Moreover, the latter may indicate a possible acceleration in the system. The appearance of chaotic strange attractors occurs due to a cascade of bifurcations of doubling the period. We also consider the dynamics of a perturbed system which arises due to the addition of «white noise» modeled by the Wiener process to one of the equations. Changes in the dynamics of a perturbed system compared to an unperturbed one are studied: chaotization of periodic regimes, the appearance of noncompact trajectories, and the premature destruction of strange attractors. In this paper, phase portraits, maps for the period, graphs of system solutions, and a chart of dynamical regimes are constructed using the Maple software package and the software package «Computer Dynamics: Chaos» (/http://site4.ics.org.ru//chaos_pack).

Analysis of available literature shows that nowadays an advanced scheme of the technological process and new designs of operating elements of the subsoiler working in conditions of deblocked cutting has been developed. The aim is to improve the quality and to reduce the energy consumption by machines and equipment during deep tillage. However, at present, the theory of vibrations and strength loading of the units of subsoiler, when its operating elements interact with soil, is not sufficiently developed. This paper highlights the issues regarding the modeling of soil during interaction with operating elements of a subsoiler. Based on the use of the Rakhmatulin model of a compressible plastic medium and the Ilyushin «flat cross-section hypotheses», the equation of the soil motion is formulated, and the dynamic phenomena occurring in the soil and subsoiler elements under variable traction are described. The calculation results are obtained in the Maple-8 programming environment using the methods of solid mechanics and soil mechanics.

The problem of the impact of the mathematical model dimension on the calculated intraballistic characteristics of a shot for the charges made of granulated powder is considered. Mathematical models of the shot are studied using the spatial (axisymmetric), one-dimensional, and zero-dimensional (thermodynamic) formulations. The thermodynamic model takes into account the distribution of the pressure and velocity of a gas-powder mixture behind the shot for a channel of variable cross-section. Comparison of simulation results is carried out in a wide range of loading parameters. It is shown that there is a range of the loading parameters for a thermodynamic approach to give satisfactory approximation to the parameters obtained using the gas-dynamic approach, which describes the flow of a heterogeneous reacting mixture with a separate consideration of phases and intergranular interactions between them. Notably that in the entire range of the charging parameters studied in this work, the one-dimensional and twodimensional gas-dynamic models only slightly differ from each other. Therefore, in the main pyrodynamic period, the actuation of the charge, made of granulated powder, can be simulated using a one-dimensional gas-dynamic model or a zero-dimensional thermodynamic model with allowance for spatial distribution of the pressure and velocity of the gas-powder mixture.
La tecnología 5G: Determinante en la disputa por la hegemonía económica global entre China y Estados Unidos en el siglo XXI

Published: December 2021

La tecnología de quinta generación (5G) es actualmente la última manifestación del avance científico tecnológico en el mundo, la cual está impactando en la esfera económica, política, en las relaciones internacionales y en la seguridad nacional e internacional de los países. Hasta ahora, China ha liderado su implementación, lo que la ha hecho adquirir un papel relevante en la gobernanza mundial, de tal modo que ha dado lugar a un enfrentamiento con Estados Unidos en el contexto de la disputa por la hegemonía económica global. La hipótesis del texto es que el avance que tiene China en la tecnología 5G será un catalizador para su posicionamiento como primera potencia económica global. En el artículo se analizan las características de la tecnología 5G; posteriormente su importancia en China y el mundo; asimismo, se revisa la carrera hacia la supremacía tecnológica, reconociendo el papel de la 5G en los sectores claves del posicionamiento económico de China en la economía global, lo que a la postre, le facilitará su ascenso y predominio en la lucha directa que mantiene con Estados Unidos.
LEFEBVRE VE FOUCAULT’DA MEKÂN: KURAMSAL BİR TARTIŞMA
Authors: KARAÇİZMELİ Mahmut
Published: December 2021

Felsefede zamanın mekâna karşı kurduğu egemenliğin sarsılmasında, “mekânsal dönüş” döneminin önde gelen iki düşünürü Henri Lefebvre ve Michel Foucault’nun payı yadsınamaz boyutta büyüktür. Bu iki düşünürün mekânı ele alış şekilleri, kendilerinden sonra da geniş yankı uyandırmıştır. Lefebvre ve Foucault’un kuramları, mekânı mekânla düşünen, mekân düşüncesinin ve kent mekânının zaman içindeki dönüşümlerini açıklayan ve bütün bu tartışmaları sosyal ve siyasal pratiklerle ilişkili bir şekilde sunan yapısıyla, günümüzde de önemini korumaktadır. Lefebvre’in felsefe, tarih, fizik, metafizik, sanat, psikanaliz, dilbilimi ve ilahiyata kadar uzanan, oldukça geniş bir alana sirayet eden mekâna ilişkin düşünceleri, sonraki dönemde yapılacak çalışmalar için de sıklıkla başvurulan bir kaynak niteliğindedir. Bu çalışmada mekânsal dönüş döneminin literatürü incelenmiş, Lefebvre’in sonraki dönemlerde “mekân üçlemesi” olarak yaygınlaşacak olan kavramları açıklanmıştır. Çalışmada gündelik pratiklerle ilişkili “algılanan mekân”, erkin kurguladığı, virtüel-aktüel uzamları bulunan “tasarlanan mekân” ve Lefebvre’in “temsil mekânı” olarak adlandırdığı ve heterotopi kavramıyla bağlantılı, farklılıklara ve dirençlere referans veren “yaşanan mekân” ele alınmıştır. Araştırmada Lefebvre’in bu kavramları, Mekânsal Dönüş Dönemi’nin bir diğer önemli düşünürü Michel Foucault’nun heterotopya kavramıyla karşılaştırılarak yorumlanmıştır. Foucault’da farklılıklara, norm dışına ve gelip geçiciliğe vurgu yapan heterotopik mekânlar, fiziki uzanımlarıyla örneklendirilmiştir. Bu çalışmanın amacı benzer dönemlerde mekanla ilgili düşünceler ortaya koyan ve sosyal bilimler, felsefe ve mimaride birçok akademik çalışmaya esin kaynağı olmuş bu iki düşünürün mekâna bakışlarındaki farkları, benzerlikleri ve kavramları kullanma biçimlerini analiz ederek mekân literatürüne katkı sağlamaktır
