Проблемы образования как последствия темпа социокультурных трансформаций

Based on the information-synergetic approach the criterion of self-organization of educational systems was established (the result of the project RFBR № 11-06-00160), itdetects paradoxes and problems of management of education modernization (the result of the project RFBR № 10-06-00313). The concept of memory-turn allows to trace cultural determinations of bioethics principles (the result of the project RFH № 12-03-00198)

Educational Environment of Pedagogical University: Integration of Communication Formats

From the standpoint of pedagogical bioethics, approaches to organise the educational environment of a pedagogical university are proposed for the effective acquisition of teaching experience by future educators. The design of the educational environment should provide an understanding of the ethical boundaries of various communication formats and an experience of performing communicative roles. The variety of these formats and roles corresponds to the variety of loci in the modern educational space

Pedagogical Bioethics Initiatives

The peculiarity of bioethics is the development of such invariant principles and rules that allow predictable variational interpretation depending on specific axiological and communicative formats of situations. The noted semiotic peculiarity is updated in connection with the project of collaboration of various universities within one region. The authors consider the success of the project in satisfying the request for the training of unique specialists. In this regard, the authors interpret the pedagogical bioethics as the training of self-defense of the individuality and as education of the desire to acquire unique experience. The authors present the directions of pedagogical bioethics, which enable: (1) to overcome the standardization of personality; (2) to become consulting for the formation of individual educational trajectories; (3) to perform the function of informed consent in the context of the implementation of innovative educational technologies based on the achievements of neurophysiology and cognitive sciences; (4) in the context of university integration, to play the role of a dominant of education in the humanities to overcome “moral color vision deficiency”. The listed initiatives of pedagogical bioethics are put forward on the base of the results of the research in the field of visual semiotics

Nonlinear Metamaterials

Metamaterials are engineered structures designed to exhibit exotic electromagnetic properties. Early on in the development of metamaterials, these properties were extended to exotic regimes of nonlinear behaviour, unknown in classical nonlinear optics. In this chapter, we give a historical overview of metamaterials, considering first their exotic linear properties, and show how these give rise to exotic nonlinear properties, at frequency ranges from RF to visible. We overview the main attractive features of metamaterials for nonlinear applications, namely their strong local field enhancement, their ability to achieve exotic phase matching conditions, and the possibility to create inclusions with the correct symmetry to enhance a chosen nonlinear process. We then summarise the two most important classes of nonlinear optical metamaterials, plasmonic and all-dielectric

Fano-Resonances in High Index Dielectric Nanowires for Directional Scattering

International audienceHigh refractive index dielectric nanostructures provide original optical properties thanks to the occurrence of size- and shape-dependent optical resonance modes. These modes commonly present a spectral overlap of broad, low-order modes (\textit{e.g}. dipolar modes) and much narrower, higher-order modes. The latter are usually characterized by a rapidly varying frequency-dependent phase, which - in superposition with the lower order mode of approximately constant phase - leads to typical spectral features known as Fano resonances. Interestingly, such Fano resonances occur in dielectric nanostructures of the simplest shapes. In spheroidal nanoparticles, interference between broad magnetic dipole and narrower electric dipole modes can be observed. In high aspect-ratio structures like nanowires, either the electric or the magnetic dipolar mode (depending on the illumination conditions) interferes with higher order multipole contributions of the same nature (electric or magnetic). Using the analytical Mie theory, we analyze the occurrence of Fano resonances in high-index dielectric nanowires and discuss their consequences like unidirectional scattering. By means of numerical simulations, we furthermore study the impact on those Fano resonances of the shape of the nanowire cross-sections as well as the coupling of two parallel nanowires. The presented results show that all-dielectric nanostructures, even of simple shapes, provide a reliable low-loss alternative to plasmonic nanoantennas
