When the character Socrates introduces his allegory of the cave at the beginning of book seven of Plato's Republic, he says that it is a story about “our nature in its education and want of education.”1 If we lack education, we grasp the passing shadows as real; if we are dragged out of the cave by force “along the rough, steep, upward way” toward the sun—that is, if we are educated—we come to recognize things as they are, and therefore the (...) error of our previous perceptions. Many readers of this allegory—from early Christian Neoplatonists to influential twentieth-century interpreters of…. (shrink)

This paper proposes a Cournot game organized by three competing firms adopting bounded rationality. According to the marginal profit in the past time step, each firm tries to update its production using local knowledge. In this game, a firm’s preference is represented by a utility function that is derived from a constant elasticity of substitution production function. The game is modeled by a 3-dimensional discrete dynamical system. The equilibria of the system are numerically studied to detect their complex characteristics due (...) to difficulty to get an explicit form for those equilibria. For the proposed utility function, some cases with different value parameters are considered. Numerical simulations are used to provide an experimental evidence for the complex behavior of the evolution of the system. The obtained results show that the system loses its stability due to different types of bifurcations. (shrink)

L'objet de cet article est de déterminer et d'analyser l'image de la Vierge Marie dans la piété russe. Dans cette culture marquée par l'Empire Byzantin et la religion chrétienne orthodoxe, la figure de la Vierge Marie n'a pas, comme dans l'occident catholique, été supplantée par des idéalisations comme Béatrix pour Dante ou l'amour courtois pour le Moyen-Age, de sorte que son image a continué de jouer un rôle prépondérant dans la piété populaire russe.

The fundamental ideas concerning computation and recursion naturally find their place at the interface between logic and theoretical computer science. The contributions in this book, by leaders in the field, provide a picture of current ideas and methods in the ongoing investigations into the pure mathematical foundations of computability theory. The topics range over computable functions, enumerable sets, degree structures, complexity, subrecursiveness, domains and inductive inference. A number of the articles contain introductory and background material which it is hoped will (...) make this volume an invaluable resource for specialists and non-specialists alike. (shrink)

Based on a nonlinear demand function and a market-clearing price, a cobweb model is introduced in this paper. A gradient mechanism that depends on the marginal profit is adopted to form the 1D discrete dynamic cobweb map. Analytical studies show that the map possesses four fixed points and only one attains the profit maximization. The stability/instability conditions for this fixed point are calculated and numerically studied. The numerical studies provide some insights about the cobweb map and confirm that this fixed (...) point can be destabilized due to period-doubling bifurcation. The second part of the paper discusses the memory factor on the stabilization of the map’s equilibrium point. A gradient mechanism that depends on the marginal profit in the past two time steps is adopted to incorporate memory in the model. Hence, a 2D discrete dynamic map is constructed. Through theoretical and numerical investigations, we show that the equilibrium point of the 2D map becomes unstable due to two types of bifurcations that are Neimark–Sacker and flip bifurcations. Furthermore, the influence of the speed of adjustment parameter on the map’s equilibrium is analyzed via numerical experiments. (shrink)

A quadratic utility function is introduced in this paper to study the dynamic characteristics of Cournot duopoly game. Based on the bounded rationality mechanism, a discrete dynamical map that describes the game’s dynamic is obtained. The map possesses only one equilibrium point which is Nash point. The stability conditions for this point are analyzed. These conditions show that the point becomes unstable due to two bifurcation types that are flip and Neimark–Sacker. The synchronization property for that map is studied. Through (...) local and global analysis, some dynamics of attracting sets are investigated. This analysis gives some insights on the basis of those sets and the shape of the critical curves. It also shows some lobes found in those attracting sets which are constructed due to the origin focal point. (shrink)

The article reviews various theories of laughter on the basis of their conventionally accepted classification. Their substantive intersections, especially significant for A. F. Losev and L. V. Karasev, are revealed. This leads us to the conclusion that there can be as many emotions and meanings expressed by laughter as there are hypotheses about what laughter points to. This conclusion drew our attention to the essential qualities of laughter, regardless of its objects, forms, and purposes: virtuality and eventuality. The theories of (...) M. Bakhtin, M. T. Ryumina, and G. Deleuze are considered in connection with these concepts. Specific attention is paid to the concept of laughter by J.-L. Nancy, which, while not excluding the ideas of the previously listed authors, as well as J. Derrida's and M. Heidegger's, is original in that it presents laughter as a presence, an autonomous event or affect, which is capable of being expressed in text and speech. (shrink)

This paper studies the dynamic characteristics of triopoly models that are constructed based on a 3-dimensional Cobb–Douglas utility function. The paper presents two parts. The first part introduces a competition among three rational firms on which their prices are isoelastic functions. The competition is described by a 3-dimensional discrete dynamical system. We examine the impact of rationality on the system’s steady state point. Studying the stability/instability of this point, which is Nash equilibrium and is unique in those models, is illustrated. (...) Numerically, we give some global analysis of Nash point and its stability. The second part deals with heterogeneous scenarios. It consists of two different models. In the first model, we assume that one competitor adopts the local monopolistic approximation mechanism while the other opponents are rational. The second model assumes two heterogeneous players with LMA mechanism against one rational firm. Studies show that the stability of NE point of those models is not guaranteed. Furthermore, simulation shows that when firms behave rational with symmetric costs, the stability of NE point is achievable. (shrink)

_Purpose._ The paper seeks to prove the thesis of the significance and importance of the theories and methodological approaches of historical anthropology, which are aimed at understanding the meanings, essence and value systems of human existence in the past for philosophical anthropology. The study of this problem is relevant for understanding the evolution of human identity with philosophical and anthropological concepts, understanding the essence of one’s own existence and attitude to the world. _Theoretical basis._ The author conducts research in the (...) analysis of the reflexive field of philosophical anthropology and related disciplines, in particular historical anthropology, implemented in the philosophical literature of recent centuries, that is, in the space of non-classical and modern philosophical thought. _Originality._ I raise and substantiate the theoretical question of the scientific significance of the analysis of human existence in the past thanks to the involvement of theoretical approaches and concepts formed in the reflexive field of modern historical and anthropological research. This forms the prerequisites for understanding complex and interdisciplinary explorations of the essence and cultural and spiritual values of human existence. I analyse the problems of the work in the context of the concept of the incompleteness of the project of philosophical anthropology without its involvement in the theoretical achievements of historical-anthropological investigations. _Conclusions._ In my opinion, modern historical and anthropological studies of the essence and meanings of being a person of the past form an extensive theoretical system. It is realized through such theoretical aspects of comprehension of human existence by historical and anthropological studies as "history of mentalities", "microhistory", "history of women", "new cultural history", "history of identity", "history of memory", history of mental aspects of political processes. Methodological approaches and concepts of modern historical anthropology form the basis of mental reconstruction and understanding of the mental and cultural causes and factors of human existence, thanks to the analysis of the evolution of the worldview, behaviour, outlook, various forms of individual and social activity of the individual.
