Anglicisms in Japanese and their cultural context
Authors: Vitković Jelena , Jotov Milica
Published: November 2020

This study aims to show the historical and cultural context of English loanwords in Japanese, the process of domestication, and the functions performed by English loanwords. The orthographic, phonetic, morphological, semantic, and syntactic modifications of borrowed words have helped their assimilation. However, linguistic and cultural loanwords have, to a certain extent, remained separated from the Japanese language and culture, which resulted in the westernization of the Japanese life and language. As a result of the economic, political, and cultural influence of Great Britain and the United States and the imposition of English as the international language, a number of world languages have adopted foreign words from English, most notably in the 20th century. There are thousands of such loanwords in the Japanese language. Many of them are well-established in the language and in everyday use. The Japanese isolation from the West was interrupted by the arrival of the US war ships at the Tokyo port in the mid-19th century. The nation was urged to accept American requests to open trade routes and diplomacy, which had further affected linguistic changes and the enrichment of the Japanese language with numerous foreign words. In the 1930s, the Japanese government was against the introduction of foreign cultures; thus, leading to the elimination of foreign words from the language during the war. However, during the six-year US occupation, the Americans oversaw and greatly influenced the rebuilding of the Japanese society. Once again, Japan invested tremendous effort to westernize its society. The eliminated words again returned to the language, and the "boom" of foreign culture adoption was restored, which has remained the case until today. The study "nihon no sankoutosho", Reference books of Japan, published by Nihon toshoukan kyoukai (Japan Association of Libraries 1980) shows that, , aided by the spread of mass media, over a half of the 25,000 borrowed words in the Kadokawa's Loanword Dictionary entered the Japanese language after World War II and most of them are taken from English. When the elements of one foreign culture and language are lent to another language, they adapt to its new cultural and linguistic context. The majority of loanwords in Japanese exhibit an orthographic, phonological, structural or semantic connection with the linguistic system of the language from which they are taken. The need to add vowels to English words to fit into the syllabic structure of the Japanese language resulted in very long loanwords. Borrowed words are often abbreviated either upon or after entering the language. This usually involves cutting off the end of a word that is left out. Blending has also occurred - it is obtained by a combination of abbreviated words which results in new expressions that do not exist in English.
“Exotic for our city”: discursive analysis in designing a tourism attraction
Authors: Gorokhovskaya Larisa Georgievna
Published: November 2020

The object of this research is the historical quarter of Old Vladivostok called “Millionka”. The article is focused on the problem of designing tourism attraction as an imaginary site. The goal consists in analysis of the strategy of such designing. The research materials contain the publications on Millionka in digital media of Vladivostok, information from the website of the City Museum of Local Lore, YouTube video of a tour. Methodologically, the article is based on the discursive analysis of the texts, which allowed viewing the peculiarities of communication strategy on designing a tourism attraction by outlining the frames of perception, central themes and concepts that form representation on Millionka, as well as determining the combination of discursive genres. The conclusion is formulated that the design of a tourism attraction is a specific cultural product that relies on the practice of creation of an “imaginary site”. The historical discourse demonstrates milestone in the existence of Millionka and allows concluding on functionality of its space as a palimpsest. Leaning on H. Lefebvre’s concept of the production of space applicable to the practices of designing an “imaginary sire”, analysis is conducted on the two forms: representation of space and space of representation. The author reveals the key peculiarities of the design of Millionka within the frame of “uniqueness and unusualness”, explores the basic strategy of exotization of the Other using the techniques of mythologization, proxemics and all-factor communication. The author underlines prevalence of the strategy of “revision of a site” and consumer discourse in designing a tourism attraction.
Strategies for the sustainable development of tourism through the design of tourist facilities (example of the Algerian coast)
Authors: Khettou Djamal , Razin Andrey Dionisovich
Published: November 2020

The development of sustainable tourism has become a growing trend in multi-level projects in developing countries aimed at supporting the economy and preserving the ecosystem. Despite the fact that Algeria is considered one of the richest and most diverse countries in Africa, the development of tourism on its 1200 km coastline faces many problems and difficulties. One of these obstacles is the lack of a comprehensive strategy that guarantees the development of the tourism sector. In recent years, the economic importance of tourism has grown significantly. However, the tourism industry without a properly planned strategy, as in the case of Algeria, cannot provide the expected economic growth. The purpose of this article is a theoretical review of various strategies for sustainable development through the development of various tourist facilities on the Algerian coast, as well as an assessment of the selected strategies for the development of tourism in Algeria in terms of urban infrastructure, ecosystems, the growth of the number and quality of architectural structures. Methodologically, this study analyzes various strategies of sustainable tourism development applied in the world. The study examines tourism development strategies and the role of designing various types of tourist facilities and resorts for the development of this industry in the coastal areas of Algeria, taking into account the conservation of natural resources and biodiversity.
Comparative characteristic of linguistic representation of the concept of Trade War in mass media of the People’s Republic of China and the United States
Authors: Kalinin Oleg Igorevich
Published: November 2020

This article is dedicated to analysis of the concept of Trade War in Chinese and American linguocultures. The initial position of the research is the thesis on unavoidable conceptualization of the objects and phenomena of the surrounding world in language, and possibility of their studying by means of conceptual analysis. The subject of this research is the specificity of representation of the concept of Trade War in media discourse in Chinese and English languages. Special attention is given to the semantic core of the concept and its speech representation in the news materials. The research methodology is based on a two-stage conceptual analysis. The first stage implies the analysis of core of the concept by means of definitional and etymological analysis of representative word; while the second stage marks quantitative and qualitative content analysis for determination of similarities and differences in peripheral meaning of the concept. The main theoretical conclusion consists in substantiation of using content analysis for determination of specificity of speech representation of media concepts. The practical result of this research lies in identification of significant differences in the concept under consideration in two linguistic cultures: Chinese media texts review Trade War primarily as a “struggle to gain economic profit”; and the US media view it as a “competition in trade industry”. The formulated conclusions largely correlate with the peculiarities of mentality of the residents of People’s Republic of China and the United States.

Authors: LI FANG-HUA  , FAN HAN-JIE  ,   中国科学院物理研究所
Published: November 2020

Cebaite Ce2Ba3(CO3)5F2 is a new mineral discovered in China. Its electron diffraction spots can be divided into two groups according to the intensity. The stronger one results from the substructure which is similar to that of Huanghoite and can be described by a hexagonal subcell with parameters α0=5.06?, c0=9.63?, while the other group comes from the superstructure which belongs to monoclinic system. The parameters of the real unit cell are α=21.2? b=5.06? c=13.l? β=95°. The possible space groups are C2/m, Cm and C2. The basic vectors of the substructure and those of the superstructure in the real space are as follows :Some frings with spacing smaller than the original one and some broad black bands often appear in lattice images formed by h00 systematic reflexions. The cause of this is discussed. It is also discussed whether there is any superstructure with longer period in this mineral.

Phase transitions of Li3VO4, Li4SiO4 and isothermal section of the pseudo-ternary systems Li3VO4-Li4SiO4-Li4GeO4 have been investigated by means of DTA and X-ray diffra-ction techniques. It has been found that the high temperature phase of Li3VO4 can be stabilized to room temperature by addition of Li4SiO4 (or Li4GeO4) in Li3VO4-Li4SiO4 (or Li3VO4-Li4GeO4) binary systems. New Li+-conductors with high Li+-conductivity has been obtained. Experimental results show that stabilization of high temperature phase exhibiting high ionic conductivity could be one of the way for exploring new Li+-conducting materials.

The ionic conduction in the systems of Li4SiO4-Li3VO4 and Li4GeO4-Li4SiO4-Li3VO4 has been studied in the temperature range from room temperature to 300℃. It is found that the γII-phase solid solution Li3+xV1-xSixO4, are good ionic conductors. Among the compositions studied Li3.3V0.7Si0.3O4 is the highest ionic conductivity which reaches 1×10-5Ω-1·cm-1 at room temperature with activation energy 0.36eV in the temperature range 42°-192℃. It's electronic conductivity is negligible, therefore it is one of the best lithium ionic conductors discovered so far. The high conductivity domains in system Li4GeO4-Li4SiO4-Li3VO4 have been roughly determined. It is found that the substitution Si for Ge in Li3.5V0.5Ge0.5O4 can cause the ionic conductivity increase. The ionic conductivity of Li3.5V0.5Ge0.4Si0.1O4 at room temperature is 1.3×10-5Ω-1·cm-1 with an activation energy 0.4eV.

Published: November 2020

The phonon spectra of C-15 phase (Hf0.5Zr0.5V2)Hx with five different composition was measured with the Beryllium Filter Detector spectrometer. It was observed that their phonon spectra vary with their hydrogen content. The result shows that the change of Tc of (Hf0.5Zr0.5V2)Hx system with x is related to the softening of their acoustic branches. The softening of acoustic branches seems favourable to the rise of Tc, while the softening of optical branches may restrain its superconductivity transition.

Published: November 2020

The dependences of luminescence peak shift and relative emission intensity of (Zn0.85Cd0.15)S:Cu, Al phosphor on hydrostatic pressure have been studied at room temperature with a high-pressure microspectroscopic system in conjunction with the gasketed diamond anvil cell, using the methanal ethanal mixture as pressure liquid, the hydrostatic pressure ranging 1bar-66 kbar was monitored by ruby R-line shift. The emission peak E(r) of (Zn0.85Cd0.15)S:Cu, Al shift to higher energy with increasing pressure, dE(r)/dP=4:.7 meV/kbar (38 cm-1/kbar), but less strongly than does the absorption edge of the host. The relative emission intensity decreases strongly with increasing pressure, decreasing by 6% when pressure increasing from 1bar to 66 kbar. The results can be explained in terms of Al3+-Cu+ donor-acceptor pair model. Finally, we estimate that dED(Al3+)/dP+dEA(Cu+)/dP=3.7 meV/kbar (30cm-1/kbar).

Published: November 2020

Magnetic domains in a magnetic bubble film have been observed in different bias fields after application of pulsed bias fields. The experimental results indicate that the formation of multifingered domains during the rapid expansion of bubbles is usually accompanied by the generation of a large amount of vertical Bloch lines (VBL). The sign of the VBL has a definite relation to the strength of the bias fields applied. On application of a series of bias pulses which are not very strong, the motion of strip domain heads leads to the generation of a large amount of VBL in the domain walls. The VBL will disappear when the pulsed bias fields are strong enough.

Authors: ZHANG YANG-ZHONG  ,   中国西南物理研究所
Published: November 2020

It is assumed in the paper that the dominant mechanism for the anomalous electron transport in Tokamaks is the renormalized electron magnetic drift wave driven by temperature gradient. A scaling law for the anomalous electron transport coefficient D(T) has been derived by solving self -consistently the kinetic process, it reads D(T)=(c/ωpe)2 {((ve/qR)2/2π+(vc/2)2)1/2 - vc/2} It coincides in numerical values with the Alcator scaling law given by the Tokamak's experiments, and it agrees with the Ohkawa scaling law in the collisionless limit (vc → 0). Furthermore, its deviation from the Alcator scaling law is analyzed, and the possibility of achieving the thermonuclear ignition for a high-field ohmically heating Tokamak is also discussed based on the scaling law.

We have calculated the project range for ions on amorphous targets made of ternary or quarternary alloys. Our calculations are based upon Vagard's law, which establishes that the project range in multi-component system can be obtained by linear combination of those of its composing binary alloy compounds. The calculated project ranges of systems, H+→GaAlAs, InAs and InGaAs, Be+→ GalnSb and InAsSb, and B+ →Cd0.2Hg0.8Te, agree well with the experimental or calculated results published in literatures. The dependences of project range on implanting energy and composition in the processes H+→ GaInAsP and GaAlAsSb, and ions→ PbSnTe are also calculated.

In this article, the critical behavior of birth-death equation for trimolecular reactionmodel has been discussed. If 1+k3A23D1)/D2)1/2]2, it is just the critical behaviorof the trimolecular model itself. The amplitudes of the unstable fluctuation waves have been taken as order parameters describing the change of fluctuation distribution near the critical point (B=Bm). By using the renormalization method to evade the difficulty due to the divergence of the fluctuation of steady solution at Bm, we obtain the generalized Landau-Ginzburg equations for the amplitudes of average values and fluctuation of partical numbers.The analytical and numerical analysis show that, as B increases beyond Bm, the variance also has a periodical stable part, the amplitude of which is very large and determined mainly by the saturated amplitudes of average particle numbers.

Published: November 2020

The problem of phase retrieval from image and diffraction patterns is of importance in electron microscopy. In this paper the true phase can be extracted uniquely and accurately by Gerchberg-Saxton iterative algorithm for the wave function, its amplitude being unity or a linear function, while its phase being a parabolic, sinuous or exponential function.A computer program for retrieving the phase has been worked out. As an image wave function is given, its Fourier transform may be calculated by the discrete fast Fourier transform algorithm. So we can recover the phase with G-S algorithm, using a random initial phase between -π and +π. The numerical examples are given in detail. The phase retrieval solution is stable under fluctuation of input initial phase up to 1 rad.

We investigated preliminarilly the synthesis and crystallization in the system TeO2-K3PO4-H2O under hydrothermal conditions. It was found that in addition to the crystals of TeO2, crystals of a new phase which we called γ could be obtained in the given range of constituent and growth conditions. The γ crystal belongs to trigonal system with α= b=10.734 ?, c=21.041?, α=β=90°, γ=120°. The formula of γ is K2Te4O9·3H2O. Furthermore,it was shown that the crystallized product in the crystallization zone depends mainly on the molar ratio of starting materials k=TeO2/K3PO4 in the system. When k≤1.90, the crystallized phase only consists of γ crystals, k≥2.22, only TeO2 crystals appears, while 1.902 are present together.Finally, the DTA curve and the relative intensities and corresponding d-values of X-ray powder diffraction pattern of γ-phase are also given.

Published: November 2020

The effects of hydrostatic pressure on the transition temperatures Tc of NH4IO3 and its solid solutions Kx(NH4)1-xIO3 have been investigated by means of differential thermal analysis (DTA) up to 10 kbar. The experimental results of Kx(NH4)1-xIO3 solid solutions indicates that the dTc/dP values are independent of the concentration of K+, although Tc decreased with increasing concentration. This appears to imply that the IO3- ions elongation under pressure will play a more important role in the pressure effect on the rising of Tc.

Authors: YANG ZHENG-JU  ,   南京大学物理系
Published: November 2020

By using the elastic dipole model of strained crystals, we regard every atom in a binary crystal as an elastic dipole, which has various effective moment. On various kinds of atoms, different force will be acted by the stress field due to other stronger internal stress sources such as dislocation, inclusion, etc. Thus different displacement will take place and some domains of various shape depending on the relative magnitude of permanent moment and induced moment will form. In the present paper, the domain patterns produced by internal stress field of edge dislocation, screw dislocation, inclusion and crowdion are obtained by calculation, they look like rosettes Under proper condition the patterns of these domains might be observed. The result also shows the effect of pressure on phase transition.

Published: November 2020

The phase transitions of LiKSO4 have been investigated by means of X-ray powder diffraction and thermal analysis above room temperature. It is established that the crystal structure of LiKSO4 between the melting point and 675℃ is isostructural with the high temperature phase of α-K2SO4 and its space group is probably P63/mmc. Cooling below Ti=675℃ , there appears an incommensurately modulated structure analogous to the incommensurate phase in K2WO4, K2MoO4, etc. The parameter κ changes with temperature from 0.492(640℃ ) to 0.500(470℃ ). At 470℃ , I→C phase transition (lock-in) takes place, after which the crystal structure becomes the superstructure lattice of the room temperature phase. At 439℃ the superstructure disappears yielding to the room temperature phase (P63).

Zylbersztejn had pointed out that the in homogeneous distribution of carriers in the edge region of the space charge region exerts a disadvantageous influence on the measurement of carrier capture cross sections of deep centers and suggested a method to eliminate this effect. However, his method can only be used to measure carrier capture cross sections at low temperature for quite deep levels. We suggest a new method to remove the harmful impact of inhomogeneous distribution of carriers (including both the inhomogeneous distribution of the carriers in. the edge region and that due to nonuniform shallow donors and acceptors) on the basis of an analysis of the dynamic process of capacitance transient. This method is not subjeer to the serious restriction of the temperature range of measurement and the situation of the levels under measuring. This is important for the study of the temperature dependence of carrier capture cross sections and the tudy of the carrier capture dynamices. As an example. the method has been used to measure the electron capture cross section of gold acceptor in silicon. The results show that the accuracy of measurement is improved.

This paper reports the spectra and the excited energy transfer in phosphate glass doped with Nd3+ and Yb3+. The transfer rates are determined experimentally, at different tempcralures. We confirme that the mechanism of energy transfer is a process in which the energy is transferred from 4F3/2(Nd3+) to 2F5/2(Yb3+) and at the same time a single phonon is emitted. The energy back transfer process from Yb3+ to Nd3+ may occur in two possible ways, one is the process 2F5/2(Yb3+)→4F3/2(Nd3+) which is accompanied by the absorption of a single phonon, and the other is the process 2F5/2(Yb3+)→4I15/2(Nd3+), being accompanied by emission of 4 phonons. Therefore Yb3+→Nd3+ transfer rate depends strongly upon the temperature. At room temperature, the transfer time from Nd3+ to Yb3+ and from Yb to Nd are 197μs and 13ms respectively. The efficiency of energy transfer is 47% for Nd3+→Yb3+ and 8% for Yb3+→ Nd3+.

Authors: QIU YUN-QING  , XIA MENG-FEN  ,   北京大学物理系
Published: November 2020

The stochastic magnetic field modifies the interaction of the waves with the electrons, and the wave-driven velocity diffusion may be effected. However, the mechanisms and the results are not all the same, if the value of correlation time of the stochastic magnetic field is different. In general, due to the effects of stochastic magnetic field, the transverse component of the electric field of waves can contribute to the longitudinal velocity diffusion, the resonant peaks of diffusion coefficient in the case of ∈>1 , the oscillating effects of diffusion coefficient are weakened. For the waves propagating nearly perpendicular to the magnetic field the effects of stochastic magnetic field on the velocity diffusion driven by the waves may be important.

Published: November 2020

By using Koster-Slater Green's function method and on-site defect potential approximation, a systematic method of A1 symmetric deep level wavefunction calculation of substitutional defect pairs is worked out. The method is applied to the spectator-oxygen pairs in GaP successfully. The Zn-O and Cd-O pair wavefunctions are obtained for the first time. The wavefunction is mainly concentrated on four bonds which locate at four nearest neighbour sites of oxygen center and point toward the oxygen. Nevertheless, the four bonds are not in the equal weight. The component of the bond which links spectator with oxygen is reduced in comparison with other three and it is more reduced for more electropositive spectator. The rest part of the wavefunction extends diversely over a wide range of space.

Published: November 2020

The microscopic defects in AlPO4 crystals have been studied by means of X-Ray diffraction topography. It was found that the major defects in these crystals are growth layers, precipitaties and dislocations. The density of dislocations is maximum near the crystal surface, and is less in the center of the crystal. The dislocation originates in thermal stress and the latticdistortion induced by the precipitaties or growth layers. The Burgers vector of most of dislocations is of the type b=(a+c) 〈1123〉, and that of the others is b=a[2110]. The relationship between growth conditions and crystal defects are analysed. We think that for improving the perfection of crystals, it is important to control temperature fluctuation during crystal growth, and especially the cooling rate after the growth process.

Published: November 2020

In this paper, the influence of interaction between magnetic impurity ions on the Kondo effect is treated by using Green's function method under the condition Tk (Kondo temperature). A self-consistent-field approximation for s-d exchange Hamil-tonian is adopted. Both of the two types of the decoupling terms, which are responsible for single-ion Kondo effect and inter-ionic interaction respectively, are retained. The Kondo temperature and the low-temperature resistivity for impurity system have been calculated. The results indicate that in dilute magnetic alloys interaction effects will decrease Tk and make the ρ-T curve in the region T《 Tk changes from 1-AT2 to 1 + BT2, with A,B > 0. Thus a resistivity maximum may probably be observed in the temperature region T k.

Published: November 2020

The paper presents a nonlinear MHD equation describing 2-D inhomogeneous magnetized plasma. Then a 2-D solitary vortex solution was given. Its structure is similar to the solution obtained in papers [2, 3], but it differs from the latter in several aspects. There is no restriction on the values of vortex speeds and the solitary waves can propagate in any direction in the plane with magnetic field B as its normal. The plasma is adhered to the vortex and moving along with it across B. This implies that the existence of solitary vortices is connected with anomalous transport of plasma.
