Consideration of singularities of mathematical education of preschool children is determined by those reforms, which are carried out in Russia over the last years at all levels of the education system. The article analyzes the singularities of the purposes, contents, forms, and methods of teaching preschool children in mathematics based on domestic and foreign publications, which have been released over the last years in the field of mathematical development of preschool children. Elements of mathematical education technology are covered according to the documents adopted in Russia, which regulate the educational activity of preschool educational institutions on the government level, and also in the context of the concept of mathematical education development in Russia.

AbstractThe article summarizes the content of Andreas Reckwitz's bookThe Society of Singularitiesin 10 theses and briefly links it to the author's overall work.The Society of Singularitiesapplies a practice theory approach in order to outline a theory of Western (late-)modernity which recognizes in it a basic rivalry between two logics of social evaluation: a social logic of the general and a social logic of the particular/ singular. The question arises which historical causes for the surge of the social logic of uniqueness since the 1980s can be discerned, which structural features this type of society unfolds and which social and political consequences it has.

This chapter is updated from the French version of the translated book that was published in France in 2007 (Le défi indigène; Entre spectacle et politique, Paris, Au Lieu d'etre.)"Indigeneity here is about mobility and inventiveness - concrete, difficult engagements with power and possibility at local, national, regional and global scales. " James Clifford ; International audience ; The paper discusses the creativity in ritual and politics performed by Indigenous people especially in Central Australia (Warlpiri people from Lajamanu) and North West Australia (Kimberley people in the Broome region) where the author has been working since 1979. The Australian situation is analysed in the light of a transplanetary Indigenous movement. In alignment with French speaking Native Americans from Quebec who define themselves as "autochtones" (" from the land "), UNESCO has adopted a protocol to use this translation in all its declarations and publications for the word indigenous instead of the French "indigène". The use of the latter word is judged politically incorrect because of its old colonial use. But some non government organisations (NGOs), whose agenda is to defend the rights of Indigenous peoples, have revalued the French expression peuples indigènes, " Indigenous peoples " to insist on their special status. A French militant reappropriation of the word "indigène" emerged in a different context with the movement " Indigènes de la République " (Indigenous people of the Republic) which was constituted in reaction to a French law that was passed in 2005 requiring schools to teach the supposed " benefits of colonisation ". The civil and academic opposition led to its withdrawal.

In this landmark work of economic sociology, Lucien Karpik introduces the theory and practical tools needed to analyze markets for singularities. Singularities are goods and services that cannot be studied by standard methods because they are multidimensional, incommensurable, and of uncertain quality. Examples include movies, novels, music, artwork, fine wine, lawyers, and doctors. Valuing the Unique provides a theoretical framework to explain this important class of products and markets that for so long have eluded neoclassical economics. With this innovative theory--called the economics of singularities--Karpik shows that, because of the uncertainty and the highly subjective valuation of singularities, these markets are necessarily equipped with what he calls "judgment devices"--such as labels, brands, guides, critics, and rankings--which provide consumers with the credible knowledge needed to make reasonable choices. He explains why these markets are characterized by the primacy of competition by qualities over competition by prices, and he identifies the conditions under which singularities are constructed or are in danger of losing their uniqueness. After demonstrating how combinations of the numerous and multiform judgment devices can be used to identify different market models, Karpik applies his analytical tools to the functioning of a large number of actual markets, including fine wines, movies, luxury goods, pop music, and legal services

Structural optimization of non-conservative systems with respect to stability criteria is a research area with important applications in fluid-structure interactions, friction-induced instabilities, and civil engineering. In contrast to optimization of conservative systems where rigorously proven optimal solutions in buckling problems have been found, for nonconservative optimization problems only numerically optimized designs have been reported. The proof of optimality in non-conservative optimization problems is a mathematical challenge related to multiple eigenvalues, singularities in the stability domain, and non-convexity of the merit functional. We present here a study of optimal mass distribution in a classical Ziegler pendulum where local and global extrema can be found explicitly. In particular, for the undamped case, the two maxima of the critical flutter load correspond to a vanishing mass either in a joint or at the free end of the pendulum; in the minimum, the ratio of the masses is equal to the ratio of the stiffness coefficients. The role of the singularities on the stability boundary in the optimization is highlighted, and an extension to the damped case as well as to the case of higher degrees of freedom is discussed.

We present a study of the dynamics and decay pattern of phase singularities due to the action of a system with a discrete rotational symmetry of finite order. A topological charge conservation rule is identified. The role played by the underlying symmetry is emphasized. An effective model describing the short range dynamics of the vortex clusters has been designed. A method to engineer any desired configuration of clusters of phase singularities is proposed. Its flexibility to create and control clusters of vortices is discussed. ; This work was partially supported by the Generalitat Valenciana (Contracts No. ACOMP07/221, No. GV2008-032, and No. APOSTD/2007/052) and by the Government of Spain 8Contracts No. FIS2005-01189 and No. TIN2006- 12890). ; Peer reviewed

Abstract
In this article, Andreas Reckwitz replies to the four critical commentaries of Patrick Baert, Andreas Pettenkofer, Austin Harrington and Sally Haslanger on his book The Society of Singularities. In this context, he discusses the general position of this book within the landscape of contemporary social theory and the question of what a 'social logic of the unique' means. He enters the question in how far his analysis of the new middle class differs from Pierre Bourdieu's analysis of the new petty bourgeoisie, emphasizing the combination of an orientation towards inner experience and social prestige in his account of the new middle class. He discusses the question of whether neoliberalism is responsible for the proneness to disappointment which the late-modern culture of self-actualization implies. Finally, he works out the differences between the type of critical analytics which his book implies and normative critical theory.
