Authors: Sánchez Ruiz Inmaculada Concepción , Áviles Hernández Manuela , García Escribano Juan José
Published: December 2020

En el año 2007 se aprobó, a nivel nacional, la Ley Orgánica 3/2007 para la igualdad efectiva de mujeres y hombres. Ese mismo año, en la Región de Murcia, se aprobó la Ley 7/2007 para la igualdad entre mujeres y hombres y la protección contra la violencia de género. Ambas leyes establecen la obligatoriedad a las administraciones públicas de elaborar y ejecutar planes de igualdad. El objetivo del trabajo de investigación que se recoge en este artículo es identificar y analizar los planes de igualdad de oportunidades entre mujeres y hombres que se han aprobado en los Ayuntamientos de la Región de Murcia hasta el año 2017. Teniendo en cuenta el objeto de estudio, se ha recurrido a una metodología cualitativa, centrada en la revisión documental. En la investigación han participado 40 municipios de la Región de Murcia. Se ha podido trabajar con 28 planes de igualdad implantados a nivel local desde 1992 hasta 2017. Los resultados del análisis indican que no existe un desarrollo adecuado de planes de igualdad de oportunidades entre mujeres y hombres a nivel local en la Región de Murcia. Destaca el escaso progreso institucional y se aprecia una carencia respecto a medidas específicas para prevenir las desigualdades de género en todos los ámbitos de la realidad social.

In 2007, Organic Law 3/2007 for the effective equality of women and men was approved at the national level. That same year, in the Region of Murcia, Law 7/2007 was approved for equality between women and men and protection against gender violence. Both laws establish the obligatory nature of public administrations to prepare and execute Equality Plans.

The objective of this research is to analyze the content of the Equal Opportunity Plans between women and men that have been approved by the City Councils of the Region of Murcia until the year 2017. Taking into account the object of study, a qualitative methodology, focused on documentary review. 40 municipalities in the Region of Murcia have participated in the research and it has been possible to work with 28 Equality Plans implemented locally from 1992 to 2017. The results of the analysis indicate that there is no adequate development of Equal Opportunity Plans among women. and men locally in the Region of Murcia. The low institutional progress stands out and there is a lack of specific measures to prevent gender inequalities in all areas of social reality. This research is a starting point towards a new approach to equality policies in the Region of Murcia, aimed at promoting, making visible and achieving real equality by eliminating gender-based social inequalities.

Spændinger mellem testdata og valg af læremidler. Et virksomhedsteoretisk perspektiv på læsevejledning i skolen
Authors: Kiær Karina
Published: December 2020

Denne artikel undersøger spændinger i forholdet mellem læsevejledning og undervisning belyst i forholdet mellem testdata og læremidler. Artiklen er er en del af et igangværende ph.d.-projekt[1], hvor jeg har skygget fire læsevejledere på tre forskellige skoler i to forskellige kommuner samt gennemført interviews af læsevejlederne og deres skoleledere.  Data analyseres med udgangspunkt i den kulturhistoriske virksomhedsteori med særligt fokus på at belyse de spændinger, som er i virksomhedssystemet. På baggrund af analysen kan jeg konkludere, at læremidler foreslås, når testdata skal bruges i undervisningssituationer. Analysen viser, at læsevejlederens fagdidaktiske viden om både læseudvikling og staveudvikling er vigtig, når det handler om at understøtte lærerens hensigtsmæssige brug af læremidler i forhold til testdata. I artiklen viser sig en tydelig spænding omkring forholdet mellem regler, arbejdsdeling og tid, fordi det har en betydning for fællesskaber (vejledning) på skolerne.

Da morte onipresente a um novo olhar da visitação, militância social e reforma da igreja: o caso metodista no século XVIII
Authors: Renders Helmut
Published: December 2020

O artigo estuda como o metodismo inglês enfrentou o duro impacto das calamidades nacionais sobre as vidas das pessoas, seja em forma de epidemias ou injustiças legalmente estabelecidas, pela compreensão da práxis da visitação de enfermos e pobres como meio da graça de Deus, pela fundamentação teológica da denúncia e do ativismo social nos conceitos da justiça e da misericórdia e pela criação de encontros religiosos, as festas do amor, que colocaram permanentemente o serviço aos pobres no centro da celebração. Como método, aplica-se um estudo bibliográfico de fontes primárias e secundárias com o objetivo de entender melhor como o metodismo na práxis procurou contribuir para “a reforma da nação, em particular, da igreja” (John Wesley). Espera-se como resultado uma inspiração para a práxis do enfrentamento de crises sociais ou de saúde pelo cristianismo de hoje.

Massification of culture and art on the example of the activity of modern libraries
Authors: Alikhanova Veronika Levanovna
Published: December 2020

This article reviews the transformation of book culture in the context of activity of modern libraries, as well as the impact of government cultural policy upon this phenomenon. Special attention is given to the changes in the activity of libraries within the framework of national project “Culture” and model standard of the activity of public libraries. In The author underlines the transformation of the phenomenon of library, and the result of these processes reflected in blurring the distinctions between the upmarket and mass, and turning the audience into mass “consumer”. In the course of this research, the author applies functional analysis, dialectical method, and comparative analysis for consideration of the functions of modern library in relation to the historically first forms of their activity. The novelty consists in systemic and nonlinear analysis of the process of transformation of libraries, taking into account incoherence of this process. Emphasis is placed on the transformation of library as a cultural phenomenon, its essence, which leads to the vague understanding of the concept of library, and thus, result, loss of its uniqueness and dysfunction as a sociocultural institution.
Methods of historicization of estate landscapes of Moscow
Authors: Chernyavskaya Elena Nikolaevna
Published: December 2020

The object of this research is the methods used in design practices of post-Soviet time to give historical appearance to landscapes of former estates of Moscow region, which faded away, i.e. the methods of historicization. The landscapes under review are being protected by the government as the objects of Moscow cultural heritage, and designated as museums (reserve museums) and public parks. The subject of this research is disclosure of the essence of these methods and their assessment from the perspective of alignment with historical primary sources, implementation, proliferation, and attractiveness. The author conducts systematization of methods in accordance to the degree of conformance to the historical realities, and divides them into the following groups: 1) that provide accurate reproduction of historical forms, 2) that create similarities, 3) that create new forms. Each group is divided into subgroups. By frequency of application, the leading place belongs to the methods of first group, which are aimed at reproduction of the shapes of buildings and structures. The rest two methods focus on reviving the memory of the past. The application is attributed to new construction, which can be assessed as landscape evolution and a modern artistic phenomenon. The methods of second group lead to landscape development in spirit of historicism, while the methods of third group – to the development of territory based on modern vision of the past. The conducted analysis is valued for the general outlook upon the process of preservation of one of the most complex types of cultural heritage of Moscow.

In this paper, we obtain a general equation for determining the resonant frequencies of all the modes in an open resonator in the form of waveguide with slow-varied cross section, which has any shape of longitudinal profile. The method to solve the field longitudinal distribution function in the resonators is investigated. As examples, we derived formulas for determining the resonant frequencies of all the modes for two kinds of resonators that have drum shape and dual-cone shape intersurfaces.A good agreement between the theoretical analysis and the experimental results has been demonstrated.

Authors: WANG DE-NING  , CHENG ZHAO-NIAN  , WANG WEI-YUAN  ,   中国科学院上海冶金研究所
Published: December 2020

Based on Thomas-Fermi potential, we derived an analytical expression of the total range R=2/a[E1/2-A1(arctg(2E1/2-f)/△1/2+arctg f/△1/2)+B1ln((E1/2-f)2)/(E-fE1/2+d)·d/f2], where A1, B1, a,f, d, and △ are constants related to mass and atomic number of the ion and the target. Combined with the derived hyperbolic relation η=Rp/△(Rp) =F(μ)·[A2(μ)+(B2(μ))/(ε1/2+C)], and linear function ω=Rp/△Rp=A3(μ)ε1/21/2+B3(μ), R,Rp and △Rp can be calculated easily and accurately. Here, Rp and △Bp are project range and standard deviation respectively, C is an empirical constant, and F(μ), A2(μ), B2(μ), A3(μ) and B3(μ) are all algebric functions of μ, the mass ratio of the ion and the target. By Comparing with numerical solutions of Gibbons et al. and experimental results published in literature, we conclude that our expressions can be used to both light or heavy ion implantation into Si, GaAs or SiO2 target. The physical significance of our expression was discussed also.

COMPOSITE LATTICE OF TWO PHASES WITH A COINCI-DENCE SITE LATTICE RELATIONSHIP (Ⅰ)——COINCIDENCE SITE LATTICE
Authors: YANG QI-BING  ,   中国科学院金属研究所
Published: December 2020

Two new methods to find the basic vector correspondence matrix of the coincidence site lattice for two phases have been developed by means of theory of matrix and elementary theory of numbers. Based on these methods the three equations which are applied to find a coincidence site lattice have been incoporated into a single one so that the problems concerning the composite lattice of two phases with a coincidence site lattice relationship are greatly simplified. It has been verified that the whole of selfcoincidence problems in the cubic system, the most of self-coincidence problems in non-cubic systems and a part of inter-coincidence problems can be simplified by the incorporating of discriminant equations.

We suggest a new efficient method of laser tuning: the principle of tuning and amplification by self-injection. By this means, the influence of tuning elements on the laser output power is reduced to a minimum, that is, the tuning efficiency can approach 1. This provides a possibility for laser outputs of both high power and narrow bandwidth to be obtained with one laser oscillator. The theoretical and experimental results are given.
THEORETICAL ANALYSIS OF THE TWO-MAGNON RAMAN SPECTRA OF RbNiF3
Authors: ZHENG HANG  ,   浙江大学物理系,杭州上海交通大学应用物理系
Published: December 2020

Two-magnon Raman spectra of RbNiF3 are calculated for the temperature range between 0 K to Néel point TN(= 133 K). From considerations of the general symmetry principle and the experimental results, we have derived the Hamiltonian of interaction between the magnetic system and the radiation field. The method of the equation of motion of retarded Green's function is used to obtain the analytic expression of the two-magnon Raman scattering intensity. In the two-magnon propagator, both the effects of energy renormalization and the life time have been taken into account. Finally, quantitative calculations are performed with proper approximations using computer. Although there are no adjustable parameters, the results account very well for the observed temperature dependence of both the. peak position and the line width in the range from 0 K up to TN.

Published: December 2020

Using (20-300K) Hall coefficient measurement and (6-300K) IR optical absorption, thermal donor generated in P-CZ Si single crystal after heat treatment at 450℃ over a wide range of time has been studied. It is shown from Hall coefficient measurements that two donor levels in the specimen after 100 hrs. annealing are observed: E1= 56 meV, E2= 110 meV. Low temperature IR optical absorption of specimens after annealing of different duration shows complex structure arising from thermal donor. The intensity and number of the absorption peaks increase with increasing duration of annealing. The results obtained can be phenomenologically explained fairly well by the hydrogen-like effective mass approximation theroy assuming the occurence of different species of doubly charged donor. The oxygen-related thermal donor can also be possibly understood as doubly charged donor. The number of species of thermal donor is closely correlated to the duration of annealing.

Published: December 2020

The internal friction (49kHz), ultrasonic attenuation (4-82 MHz) and Young's modulus associated with martensitic transition (MT) were measured in AuCd alloys containing 46.1 at%, 47.5 at% and 52.5 at% Cd respectively.The internal friction due to MT in the kHz range was confirmed as the hysteresis loss just the same as we have disclosed in the Hz range. The origin of internal friction peak was explained by elastic softening and the interaction of the interface dislocations with point defects. But the ultrasonic attenuation in the MHz range is frequency dependent, this implies that there exist components of resonance and relaxation loss contributed by viscous motion of dislocations.In addition, the isothermal martensitic transition peak and the premartensitic phase transformation peak in AuCd alloys were observed as well.

Published: December 2020

Theory and experiments of a new spectrochemical analysis technique using a white-light image processing system are described. The spectrochemical analysis can be accomplished in three steps: (1) spatial encoding of two spectrograms to be tested, (2) color filtering at the Fourier plane in white-light optical image processor, and (3) colorimetric measurement in the output plane. Compared with existing methods of spectrochemical analysis, the present technique requires only one white-light processor and a single film of encoded film, therefore it is much simpler and more economical to use in practical applications.
MEASUREMENT OF HYDROSTATIC PRESSURE EFFECT ON OPTICAL ABSORPTION EDGE OF AMORPHOUS As2S3 USING HIGH-PRESSURE MICROSPECTROSCOPIC SYSTEM
Authors: ZHA CHANG-SHENG  , GUO CHANG-XIN  ,   中国科学技术大学
Published: December 2020

Shift of optical absorption edge of amorphous As2S3 with increasing hydrostatic pressures up to 66 kbar has been quantitatively measured by means of high-pressure mic-rospectroscopic system in conjunction with gasketed diamond anvil cell under room-temperature. The method of ruby fluorescence shift technique was adopted for pressure calibration. Amorphous As2S3 thin film samples a few micrometers in thickness were prepared by vacuum evaporation. Under our experimental conditions, neither the light of 4416? He-Cd laser used for excitation of the ruby gauge, nor that of the Br-W lamp for measurement of light transmission, showed any detactable influence on the optical properties of the sample. Rapid red-shift of optical absorption edge with increasing pressure was observed, Eg dropped from 2.58 eV to 1.95 eV between 1 bar and 66 kbar. An empirical formula of experimental data was obtained. The relationship of absorption edge and pressure is as follows: Eg(P)=Eg(0)-1.31×10-3P-3.91×10-4P2+4.04×10-6P3. It is noteworthy that the dependence of |dEg/dP| upon pressure was increasing at first and then decreasing gradually to saturation at high pressure. This result shows something different from privious one obtained by Weinstein et al. The origin of the difference was discussed.

Published: December 2020

The critical properties of a quenched site-correlated percolation system is treated by real-space renormalization group method. We chose the nearest-neighbour short-range order a as the correlation parameter. By treating the correlated probability self-consistently, we found, in two dimension, there is only one nontrivial physical fixed point and the correlation is an irrelevant parameter at random percolation fixed point, which is consistent with other correlated percolation models.

The Multichannel Quantum Defect Theory (MQDT) has been applied to the analysis of the 2D absorption spectrum of atomic aluminium. The model consists of the mixing of three dissociation channels with different ionization thresholds. By suitably taking the values of the eigen-parameters μα,Dα which depend on electron energy and on the transformation matrix elements Uiα, the 2D autoionization spectrum between the first and second ionization limits is calculated and the result is compared with Roig's measurements. Extending the se parameters to the region of discrete spectrum, we obtained the Rydberg series of 2D energy levels as well as their oscillator strengths which also coincide with the analyses of Lin and Weiss and related experiments.
STUDYING THE LAWS OF DEPENDENCE OF REFRACTIVE INDICES OF AMORPHOUS As2S3 ON HYDROSTATIC PRESSURE USING HIGH-PRESSURE MICROSPECTROSCOPIC SYSTEM
Authors: GUO CHANG-XIN  , ZHA CHANG-SHENG  ,   中国科学技术大学
Published: December 2020

The pressure and wavelength dependence of refractive indices of amorphous As2S3 have been studied by means of observing transmission light interference spectrum under room temperature with the high-pressure microspectroscopic system in conjunction with the gasketed diamond anvil cell, in which methanol-ethanol mixture was used as pressure liquid with hydrostatic pressure up to 66kbar and wavelength between 400-900 nm. The pressure was monitored by ruby R-line shift. Amorphous As2S3 thin film samples a few micrometers in thickness were prepared by vacuum evaporation. Under our experimental conditions, neither the light of 441.6 nm He-Cd laser used for excitation of the ruby gauge, nor that of the Br-W lamp for measurement of light transmission, showed any detectable influence on the optical properties of the sample.By observing the interference maxima at energies below the absorption threshold and using the results of. Gerlich et al. of the pressure dependence of volume of a-As2S3, the pressure dependence of refractive index between 500-850 nm have been determined. The refractive index of amorphous As2S3 is significantly pressure-sensitive, increasing by 35% at 650 nm with pressure change of 66 kbar. Analysis of experimental data by least-square method on the computer gives the coefficients of the nonlinear formula n(p)=n(0)+Ap+Bp2, where n(p) and n(0) are refractive indices at pressure p and 1 bar, respectivelly; coefficients A and B are relative to wavelength, for example {A=9.62×10-3 kbar-1,B=2.07×10-3 kbar-2, for wavelength) λ = 800nm and other values were given in the paper. This relationship is different from the results of Weinstein et al. and Galkiewicz et al., where linear relationship between n and p at fixed wavelength in infra-red regime was reported. The difference, however, may be attributed to the different method of sample preparation etc.

Two systems of single cry stals of BaFe12-2xCoxTixO19(with x=0, 0.04, 0.09, 0.13, 0.27, 0.68) and BaFe12-x(Nb1/3Cu2/3)xO19(with x = 0, 0.28, 0.44, 0.60) were grown from Bi2O3 melts. Magnetization a and anisotropy constant K1 of the above samples were measured in the temperature range of 100-300K. For the substitution with Co2+-Ti4+ ions, it was found that when x = 0.09 σ and K1 increased slightly with x at the beginning and decreased rapidly when x > 0.09 until K1→ O at x≈ 1.1. In the case of substitutions with Cu2+-Nb5+, the σ value was nearly the same in the studied compositions and showed a slightly increasing trend with increasing x; while K1 decreased monotonously with x. Our results were qualitatively discussed with the model of site occupation of substitution ions in the M-type hexagonal ferrite.

The effect of additive Al2O3 on both the formation of amorphous B2O3-0.7Li2O-0.7LiCl and it's ion conduction property have been studied. It has been found that rather large slab of amorphous material could be easily prepared by pouring directly the melt contained suitable amount of additive Al2O3 onto a copper plate at room temperature without using liquid nitrogen.The additive A12O3 decreases slightly the conductivity of amorphous B2O3-0.7Li2O-0.7LiCl but in high temperature range this effect is far less obvious because of the activation energy for the amorphous containing Al2O3 is slightly larger than that of pure one. It has been shown that Al2O3 = 0.03 is the optimum content which makes the preparation of amorphous more easily and dose not seriously influence the conductivity.

If SU(2) potential Aμ, with Dμφ=?μφ+ Aμ×φ, can be expressed by n(xμ) with n ·n = 1 as Aμ= ?μn×n, we call it "deduced potential". Because Dμn = 0, it can be transformed into Abellian. Then, we find equivalent U/(l) potential and strength of field Fμv = Fμv ·n. This kind of Fμv (namely Ei and Bi) has the same specific properties and relations between E, B and n. Using this properties and relations, from the known strength of electric and magnetic field of monopole, we can construct a n = n(xμ) with n·n = 1. Then obtain the potential Aμ and its equivalent U(1) potential Cμ. In this way, we find a definite expression of potential for a moving monopole just like the Lienard-Wiechert potential for a moving charged particle. When monopole is at rest, the potential reduces to the famous Wu-Yang potential.

Published: December 2020

Fringe images of overlapping micro-twin boundaries in a f.c.c. Ni-Cr alloy have been observed by trausmission electron microscopy. It is shown that the average intensity of the fringe images in the overlapping boundary is either much higher or much lower than that of the single boundary depending on the sign and value of the deviation parameters. The contrast of fringes will reverse when one changes the sign of deviation parameters for the matrix and/or the twin. Comparing with the well-known α-fringe and δ-fringe, overlapping twin fringes have special features which may arise from the anomalous absorption-anomalous transmission effects and the dynamic multiple beam interference among the matrix-twin-matrix or twin-matrix-twin. Using Van Dyck's iterative method, simulation images were calculated which are in good agreement with experimental observations.

In this work, the phenomena of excitation of SWR (Spin Wave Resonance) in magnetic films are investigated. On the basis of Partis' Volume Inhomogeneity (Ⅵ) Model, the Asymmetric Volume Inhomogeneity (AⅥ) Model and the Surface-Volume Inhomogeneity (S-Ⅵ) Model are proposed. In terms of these models, we can explain satifactorily the linear spectra of SWE, in which the odd and even modes are excited simultaneously with their intensities changing in accordance with different envelopes.

The linear spin-wave spectra in Fe-Ni polycrystalline films and YIG single crystal films have been observed. It is found that in the spin-wave spectrum of magnetic film the odd and even modes are usually excited simultaneously, and their intensities change in accordance with different envolopes. Further investigations indicate that the positions and relative intensities of the odd and even modes vary with the depositing process and annealing of the film. All these experimental results can be well explained in terms of the Surface-Volume Inhomogeneity (S-VI) Model and the Asymmetric Volume Inhomogeneity (AVI) Model. In this paper the equipment and the relevant methods for measuring the spinwave spectrum are also described briefly.

The crystal structure of the ternary compound Y(Mn1-xCox)12 With x = 0.3, 0.5 and 0.6 is body-centered tetragonal of ThMn12 type. The space group is I4/mmm, z= 2. Powder neutron diffraction studies on this system has been performed to determine the possible ordering of the Co and Mn atoms on 3 nonequivalent crystallo-graphic sites 8i, 8j and 8f. The structure analyses at room temperature shows that the Co atoms tend to occupy the 8f sites primarily and then the 8j sites. They avoid the 8i sites when x is lower than 0.67. The experimental result is discussed and an inference is drawn.

Rosenbluth et al. have suggested that energetic particles trapped at unfavorable curvature region of a tokamak can provide an access to the second stability region. The ECRH processes for achieving this novel state in reactor tokamak is proposed. The RF within the proper ranges of frequency and wave vector are injected from the outside of tokamak of a chosen magnetic surface. Only a few percent of electrons is heated by the high electron cyclotron harmonic resonance successively. The numerical results show that heating is efficient for both ordinary and extraordinary modes.

One dimension angular correlated positron annihilation radiation curves of amorphous lithium ionic conductor B2O3-0.7Li2O-0.7LiCl-xAl2O3 (x = 0.15, 0.10, 0.05) during the crystallization process have been measured, and the linear parameters S in normalized dispersion of electron momentum have been calculated. From the parameters S we can also disclose the variations in defect-density during the crystallization process.Experimental results show that the parameters S at room temperature are not Largely affected by the content of Al2O3, each and all greatly decrease after full crystallization process, each and all slighly increase at the beginning of crystallization, but then increase anomalously at about 400-450℃ only when x= 0.15. These results verify and complement the results obtained from measuring average positron lifetime. From them we are convinced of the physical picture that the boundary layer contains a lot of defects.

Authors: He Kai-fen  ,   北京师范大学
Published: December 2020

A Hamiltonian system with coupled two dibberent kinds of modes is studied. When the coupling vanishes, one kind of modes is nonlinear oscillators, describing coherent three-wave interaction and consisting an integrable Hamiltonian. Another kind of modes is constants of motion. In the first order of approximation, resonance occurs due to the coupling between these two kinds of modes. The resonace condition is relevant to the existing linear brequencies and their mismatch as well as the harmonic frequencies of the nonlinear variations of the amplitudes of the oscillators.

Published: December 2020

As is shown by westervelt, the difference-frequency sound pressure of the parametric array in the far field is proportional to the second power of f/f0, the downshift ratio of the frequency. However, a different result may occure in the near field, especially, when the distence to the field point is much less than the length of the parametric array, but larger than R0, the Rayleigh length of the transducer. In this paper, our previous theory is applied to the case of shallow water and an expression for the parametric array design has been given. It is shown that the parametric pressure is proportional to Ro, instead of proportional to the length of the parametric array or to the second power of f/f0. Futhermore, an analysis for Moffett and Mellen's theory is also made in this paper and on identical expression has been obtained. Finally, an experiment is carried out in a pool and the results obtained support the theory.
