The concept of activity focuses on the uniqueness of human social life, which consists of the fact that men purposively transform objective nature and social reality. The characteristic feature of the social life of human beings is that it is manifested only through their activity, which has various aspects and forms.

The subject matter of the article is a standard cosmological model of the Universe. Contemporary opinion regarding origin, structure, and evolution of the Universe is of great interest. The answer to the question of the Universe origin is given by the Big Bang Theory. Is it possible to be sure in this theory correctness, which persuading of the Universe origination from the singularity fluctuation, when the World had appeared from nowhere, that is from abstract nothingness, further accelerated expansion of the (...) Universe following the Big Bang, and its development up to present with inexplicable source of energy for that. However, in the extreme end of the meta-universe the speed of stellar formations runaway is about the light velocity. Further, there is a new problem, the finiteness of the Universe. There are two counter-opinions, if the expanding Universe is finite or infinite. A very important question arises here, the question regarding isolatedness of the Universe as a system. The problem of the Universe heat death is closely connected with it. For this reason it is the time to discuss the Universe entropy. There is a short description of notions and problems with reference to this branch of knowledge, as well as of Doppler and Ritz effects alongside with Habble Law. The authors’ detailed interpretation of an entropy is also suggested. The analysis of the existing model is followed by the idea of the authors about the Universe organization. The style of the article is popular-science. In the first part of the article the existing concept of the Expanding Universe Theory and the dynamical Friedmann-Lemaitre models are described; it deals with the existing concept of the Big Bang Theory as well as the dark energy and the dark matter notions. In the second part the author gives detailed interpretation of an entropy. In the last part the problem of theoretical basis and fact nonconformity within the Expanding Universe Model Theory and the authors’ idea about the Universe organization are considered. (shrink)

We are demonstrating that the Luttinger model with short range interaction can be treated as a type of Fermi liquid. In line with the main dogma of Landau’s theory one can define a fermion excitation renormalized by interaction and show that in terms of these fermions any excited state of the system is described by free particles. The fermions are a mixture of renormalized right and left electrons. The electric charge and chirality of the Landau quasi-particle is discussed.

One of the most important philosophical principles in contemporary natural science is the principle of the universality of evolutionary development , which was argued with much force and depth in F. Engels's The Dialectics of Nature. For the more than a century that has passed since Engels's sweeping synthesis of knowledge in the natural sciences, his revelation of the unity of the processes of evolution in inanimate and animate nature, including the inevitably and law-governed appearance of its "highest flower, the (...) thinking mind," where appropriate conditions for that appearance arise, this principle of development has assisted in the achievement of many impressive advances. The general outlines of the evolutionary process of nature, in its infinite diversity, are now emerging in ever sharper relief, although our knowledge of that process still contains many rather serious lacunae. It is significant to note that the progress of natural science leads not only to modifications but often even to radical revisions of many notions about the evolution of nature, including those that seemed unchallengeable.

This set reprints volumes that were orginally published by Routledge and Kegan Paul Ltd. in 1953. Landmark volumes at the time of their original publication, these titles do not merely expound the theoretical constructions of Russian philosophers, but also relate these constructions to the general conditions of Russian life. Volume One examines the historical conditions of the development of philosophy in Russia and explores the general features of Russian philosophy. It also surveys the principal works on the history of Russian (...) philosophy. Volume Two includes biographies and examination of the themes of the following philosophers; Vladimir Solovyov, V.D. Kudryavtsev, N.F. Fyodorov and Later Hegelians such as Chicherin, Debolski and Bakunin. This volume also provides analysis of various schools of thought in Russian philosophy in the twentieth century, for example; Neo-Leibzianism, Modern Positivism and New-Marxism to name but a few.

Former research showed that up to 20–25 % of those who leave schools of type VIII are referred to nursery homes for chronic mental patients not due to medical problems but because of social ones. According to the authors’ opinion, such social practice has more positive than negative aspects. However, this issue requires extensive discussions. Organizing special post-diploma training courses of 16–24 hours on ethical-psychological aspects of referral various categories of patients to nursery homes for chronic mental patients also seems (...) to be reasonable.

The transition of various countries to socialism is giving birth to a constantly increasing diversity of concrete forms of implementation of the functions of the socialist revolution. At the same time, historical experience shows that the socialist revolution is characterized by certain universal regularities, so that it is a matter of principle, of vital importance, that a revolutionary Marxist party allow for them. Among these, above all, is the need for power to be in the hands of the working class (...) in alliance with all others who labor, the need for abolishing the socio-economic dominance of the capitalist class, and for the new authority to have the capacity to overcome any form of resistance by the class opponents of socialism while uniting the masses of the workers at large in the struggle for the building of the new society. Without the organization and cohesion of the laboring masses headed by the working class, and without converting them into the determining political force, a transition to socialism is impossible: this is the most important conclusion of Marxism-Leninism. This conclusion has found precise expression, with room for all possibilities, in the theory of the dictatorship of the proletariat as the political essence of the transition from capitalism to socialism.

Context: The paper utilizes a conceptual analysis to examine the development of abstract conceptual structures in mathematical problem solving. In so doing, we address two questions: 1. How have the ideas of RC influenced our own educational theory? and 2. How has our application of the ideas of RC helped to improve our understanding of the connection between teaching practice and students’ learning processes? Problem: The paper documents how Ernst von Glasersfeld’s view of mental representation can be illustrated in the (...) context of mathematical problem solving and used to explain the development of conceptual structure in mathematical problem solving. We focus on how acts of mental re‑presentation play a vital role in the gradual internalization and interiorization of solution activity. Method: A conceptual analysis of the actions of a college student solving a set of algebra problems was conducted. We focus on the student’s problem solving actions, particularly her emerging and developing reflections about her solution activity. The interview was videotaped and written transcripts of the solver’s verbal responses were prepared. Results: The analysis of the solver’s solution activity focused on identifying and describing her cognitive actions in resolving genuinely problematic situations that she faced while solving the tasks. The results of the analysis included a description of the increasingly abstract levels of conceptual knowledge demonstrated by the solver. Implications: The results suggest a framework for an explanation of problem solving that is activity-based, and consistent with von Glasersfeld’s radical constructivist view of knowledge. The impact of von Glasersfeld’s ideas in mathematics education is discussed. (shrink)

Open peer commentary on the article “Radical Constructivist Structural Design Education for Large Cohorts of Chinese Learners” by Christiane M. Herr. Upshot: Herr’s target article outlines a teaching approach that illustrates and explains how radical constructivism can be used to teach architectural design principles to a large cohort of students. Herr’s approach consists of a hybrid set of instructional activities whose implementation was supported by her establishment of a social climate in the classroom that encouraged the contributions of individuals in (...) the learning process. The activities included the integration of lectures with other teaching formats, the use of open‑ended problem solving tasks, and the use of small‑group projects. I will discuss each of these activities and offer a recommendation for future research. (shrink)
