Sustainability of Teachers' International Experiences: Conditions for Institutionalization of International Program Outcomes
Anatoli Rapoport
Education Research International , 2011, DOI: 10.1155/2011/591276
Abstract: Since World War II international exchange and training programs for educators have increasingly played an important role in developing prospective consciousness and awareness of cultural diversity and global interdependence among teachers. However, international programs have always depended on extra educational factors such as political, ideological, cultural, or financial circumstances. As a result, program sustainability and proper institutionalization of program's results that are a testimony of achieved success, are both matters of concern for program developers and alumni. This paper identifies factors and contexts that facilitate sustainable development of international programs and institutionalization of their outcomes. Two cohorts of international teacher program alumni from Russia and the United States were interviewed about the impact of exchange programs on participants' status and pedagogies. The study demonstrated that respondents consider three factors, namely, motivational, administrative, and cooperative, most critical for the institutionalization of international program results.

Introduction As a result of major cultural and political transformations in the world, international programs in education that initially started as a means for promoting Western values [1] have become an important component in developing global awareness and cross-cultural learning. Researchers of international exchange programs predicted that (a) international educational exchanges will increase, (b) the purposes of the agencies and individuals will be clarified, (c) procedures at all levels will be improved, (d) research into all aspects of cross-cultural relations will be continued and expanded, and (d) the competence, professionalism, and understanding of the individuals involved in the operations of these programs will grow [2–5]. These predictions have been well justified. For 59 years (1949–2008), almost 29,000 foreign and more than 20,000 US educators participated in international exchange programs through Fulbright grants administered by the US Department of State [6]. More than 43,000 individuals participated in educational exchanges in 1964–2008 through Fulbright-Hays grants administered by the US Department of Education [6]. In different years, government-sponsored exchange and training programs accounted for 4 to 7 percent of all programs [7], besides the numerous international exchange programs for educators sponsored by private funds. 2.

On Ellipsoids Attached to Root Systems  [PDF]
Anatoli Loutsiouk
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.48160
Abstract:
For any finite-dimensional complex semisimple Lie algebra, two ellipsoids (primary and secondary) are considered. The equations of these ellipsoids are Diophantine equations, and the Weyl group acts on the sets of all their Diophantine solutions. This provides two realizations (primary and secondary) of the Weyl group on the sets of Diophantine solutions of the equations of the ellipsoids. The primary realization of the Weyl group suggests an order on the Weyl group, which is stronger than the Chevalley-Bruhat ordering of the Weyl group, and which provides an algorithm for the Chevalley-Bruhat ordering. The secondary realization of the Weyl group provides an algorithm for constructing all reduced expressions for any of its elements, and thus provides another way for the Chevalley-Bruhat ordering of the Weyl group.
Canonical and Boundary Representations on Rank One Para-Hermitian Spaces  [PDF]
Anatoli A. Artemov
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.411A3006
Abstract: This work studies the canonical representations (Berezin representations) for para-Hermitian symmetric spaces of rank one. These spaces are exhausted up to the covering by spaces G/H with G = SL(n,R),H = GL(n-1,R) . For Hermitian symmetric spaces G/K, canonical representations were introduced by Berezin and Vershik-Gelfand-Graev. They are unitary with respect to some invariant non-local inner product (the Berezin form). We consider canonical representations in a wider sense: we give up the condition of unitarity and let these representations act on spaces of distributions. For our spaces G/H, the canonical representations turn out to be tensor products of representations of maximal degenerate series and contragredient representations. We decompose the canonical representations into irreducible constituents and decompose boundary representations.
Mathematical Modeling of Shock Waves in Inhomogeneous Viscoelastic Two-Component Media  [PDF]
Victor Polenov, Anatoli Chigarev
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.65086
Abstract: Mathematical modeling of two-component media with a saturated liquid began over 90 years with studies of the consolidation of soils. Two-component must be taken into account when solving a significant number of applied problems arising in various areas of human activity (soils, foams, various cement mortars, sand, porous ceramics, porous sintered composite materials, etc.). Two-component media are widely used in the national economy. For example, in the construction of new airfields and the restoration of destroyed, where the building materials used contain a significant number of voids. The study of wave processes is also very important for the development of new diagnostic methods, new technologies for creating two-component environments that could be applied in the field of engineering, construction, instrumentation, metallurgy, nuclear power and the defense capability of the country. However, the complexity of describing the effects of the interaction of components, heat transfer, and other related processes has led to the fact that until now the generally accepted models (elastic medium-liquid) for a fluid-saturated two-component medium have not been fully developed. Therefore, it is of interest to develop a mathematical two-component model when one of the components represents an inhomogeneous viscoelastic medium and the other is a compressible fluid. The presence and degree of porosity in materials is accounted for by a porosity coefficient equal to the ratio of the pore volume to the total volume occupied by the medium.
Komi muusika realad: lindude maailm
Anatoli Panjukov
M?etagused. Hüperajakiri , 2011,
Abstract: The article analyses bird sounds and the expressions thereof in Komi folk music. Relying on a number of examples, the author introduces the potential emergence of linguistic, mythological and musical connections, and the relevant research in Komi folklore, observing the most meaningful levels of interpreting and understanding theworld of birds in folk tradition. Undoubtedly, the study of folk music is not only associated with the research of musical thought, but also pre-necessitates the analysis of mythological, folkloric and linguistic conceptions which serve as the basis for the ethicalneeds of people. The presented cross-section of folk culture makes it possible to see the connection between the linguistic, mythological and musical phenomena. Based on the given analysis, it can be said that in certain situations, the chronotopy and in-depth structure of bird images (at linguistic, mytho-epical and musical levels) may indeed act as the primordium for the plot. Folkloric texts generated in such a manner are cosmological in their structure, as they reflect the universal principles of traditional worldview – anthropocentrism, anthropometry and anthropomorphism, i.e. the reciprocal influence between the macrocosm and microcosm.
L’anthropologie juridique en Russie : passé et présent d’une (grande) inconnue Legal anthropology in Russia: past and present state of an (almost) unknown discipline
Anatoli Kovler
Droit et Cultures , 2009,
Abstract: L’auteur retrace l’histoire de deux siècles de l’évolution de l’anthropologie juridique en Russie en tant qu’une science appliquée, science académique et discipline universitaire. Il distingue quelques périodes de cette évolution : période de la Russie des XVIIIe – début du XXe siècles ; période soviétique et période dite post-soviétique, chaque période ayant ses particularités. Le droit coutumier des peuples autochtones occupait toujours une place importante dans les recherches anthropologiques autant que la tendance sociologique. Le thème droit et pouvoir devient le sujet à la mode au XXe siècle. Quant à la période contemporaine la prédominance de la tendance ethnologique s’efface derrière la montée des recherches en matière de la protection par le droit de l’environnement naturel, culturel et économique des peuples autochtones, mais aussi de la population toute entière. The author describes the two-century-old evolution of legal anthropology in Russia as an applied science, an academic science and a university discipline. He distinguishes some periods in this evolution: the period of Russia from the XVIIIth century to the beginning of XIXth century, the Soviet period and the so-called post-Soviet period, each characterized by its own particularities. The customary law of autochtonous peoples has always occupied an important place in Russian anthropological research studies, which have always had a sociological orientation. The theme law and power became fashionable in the XXth century. As for the contemporary period, the predominance of ethnological tendencies is disappearing with the development of research concerning the protection, by law, of the natural, cultural and economic environment as well as of the population as a whole.
Phase space representation of quantum dynamics
Anatoli Polkovnikov
Physics , 2009, DOI: 10.1016/j.aop.2010.02.006
Abstract: We discuss a phase space representation of quantum dynamics of systems with many degrees of freedom. This representation is based on a perturbative expansion in quantum fluctuations around one of the classical limits. We explicitly analyze expansions around three such limits: (i) corpuscular or Newtonian limit in the coordinate-momentum representation, (ii) wave or Gross-Pitaevskii limit for interacting bosons in the coherent state representation, and (iii) Bloch limit for the spin systems. We discuss both the semiclassical (truncated Wigner) approximation and further quantum corrections appearing in the form of either stochastic quantum jumps along the classical trajectories or the nonlinear response to such jumps. We also discuss how quantum jumps naturally emerge in the analysis of non-equal time correlation functions. This representation of quantum dynamics is closely related to the phase space methods based on the Wigner-Weyl quantization and to the Keldysh technique. We show how such concepts as the Wigner function, Weyl symbol, Moyal product, Bopp operators, and others automatically emerge from the Feynmann's path integral representation of the evolution in the Heisenberg representation. We illustrate the applicability of this expansion with various examples mostly in the context of cold atom systems including sine-Gordon model, one- and two-dimensional Bose Hubbard model, Dicke model and others.
On the Cosmological Aspects of Observed High Energy Cosmic Phenomena
Anatoli Vankov
Physics , 1999,
Abstract: Super-high energy corpuscular and gamma rays as well as cosmic high--power density sources are hard to explain in a galaxy model framework. Attempts to include some of those phenomena in the Standard Cosmological Model also encounter serious difficulties. In the present paper an alternative cosmological concept is discussed. There are several features in it. First of all, the whole Universe (Grand Universe) is a multitude of typical universes, like ours, evenly made of either matter or antimatter, hence, there is no violation of the baryon symmetry on the largest scale. Second, high-energy phenomena are the result of matter-antimatter annihilation processes in a typical universe evolution. Finally, the Ground Universe is a self-creating due to a balance of annihilation and pair creation in the inter-universe infinite space. This concept and its consistence with the major observational data are discussed in detail.
Shot noise of interference between independent atomic systems
Anatoli Polkovnikov
Physics , 2006, DOI: 10.1209/0295-5075/78/10006
Abstract: We study shot (counting) noise of the amplitude of interference between independent atomic systems. In particular, for the two interfering systems the variance of the fringe amplitude decreases as the inverse power of the number of particles per system with the coefficient being a non-universal number. This number depends on the details of the initial state of each system so that the shot noise measurements can be used to distinguish between such states. We explicitly evaluate this coefficient for the two cases of the interference between bosons in number states and in broken symmetry states. We generalize our analysis to the interference of multiple independent atomic systems. We show that the variance of the interference contrast vanishes as the inverse power of the number of the interfering systems. This result, implying high signal to noise ratio in the interference experiments, holds both for bosons and for fermions.
