政治领导人演讲的话语体系构建研究——基于近体化理论的案例分析

话语体系的要素包括话语主体、话语目的、话语空间(架构)和话语策略等。本文以澳大利亚外长在第70届联合国大会一般性辩论中的演讲稿为语料,依据近体化理论,从空间、时间和价值观三个维度对政治领导人如何构建话语空间、塑造国家形象进行了分析。文章还探讨了框架等话语策略及对其解读的范畴化、隐喻等识解操作。构建话语空间、运用话语策略、分析识解操作的最终目的是为了解读话语强制说服目的,即塑造和提升国家形象。

企业在华发展报告的批判认知分析

本研究建立包含批评隐喻分析理论、概念合成理论和近体化理论的批判认知分析框架,以《西门子公司在华发展报告》为语料,从认知视角分析企业如何应用话语策略构建话语空间,塑造和提升企业形象。研究发现,《报告》的话语策略有以下特征:(1)使用6类隐喻传递西门子对于公司治理各方面的态度;(2)通过多域复合网络构建"中国公司走出去是在竞技场上战胜对手、提升自我、超越自我过程"的层创空间;(3)从空间、时间、价值观三个维度构建西门子公司作为内部指示中心,危机作为外部指示中心的空间模型。本研究为商务话语研究提供了新的思路,未来可以从批判认知视角深层次揭示商务语篇的意义建构过程。

Daily Variability of Radon Gas in Brazilian Tropics Near Ground Level Surface

By monitoring the ionizing radiation from minute to minute in S^o Jos6 dos Campos, SP, Brazil （230 S, 450 W） using Geiger counter, during January to August 2015, it has confirmed the presence of radon gas in these measures. The observation confirms the existence of a periodicity of 24 hours through the technique （Fast Fourier Transform） applied to the data set, and this cycle can be better visible in longer dry periods. On rainy days or with heavy fog in the region, this periodicity is modified or even disappears. As Geiger do not detect alpha particles due to absorption in the walls of the sensor tube, it measured X and gamma rays coming from the radon gas progeny. Radon gas （222Rn） has a half-life of 19.7 minutes to decays in 214Bi emitting gamma ray energy （45%） with 0.609 MeV which is monitored daily by Geiger. Also 222Rn decays in 26.8 minutes in 214pb giving （37%） with 0.35 MeV and others with less energy. It is confirmed the good performance ofa Geiger tube with LND 712 working with about 500 VDC rated voltage.

Media and Peeping Tom Culture： Violating Familial Privacy and Communal Responsibility in the Evolution of Voyeurism

In the name of visual pleasure, there are different entertainments in today＇s media that instigate voyeurism among common viewers. In this study, the author intends to focus on two phases where the spectators are turning voyeurs without their consent. In the first phase, the study reveals the process where film influences voyeuristic behavior. The urge to explore others＇ private matters starts through the way film reflects, reveals, and even plays on the straight, socially established interpretation of sexual difference which controls images, erotic ways of looking, and spectacle. Several voyeuristic means in films pursue set formation, and they all persuade the viewer to identify with the male character by allowing the viewer to see what he sees through different voyeuristic means. The use of devices as a telescope, magnifying glass, and keyholes is the motivation for the close-up shots. They turn the viewer into a participant and spectator and allow the viewer to look at previously unseen and hidden details, but they do not let the viewer become totally a part of the action. In this study, films like Peeping Tom and Sliver are analyzed to understand big screen voyeurism. In the second phase, this study presents the voyeurism initiated by television programs such as reality shows, ＂soap operas＂, daytime television, talk shows, real life documentaries, and ＂docudramas＂. At the pinnacle, there are the government, police, and the employers who are assisting to produce a new ＂watched＂ culture with the use of closed circuit TV devices. Some camera operators are known to have made ＂greatest hits＂ tapes and other material captured on CCTV has become the footage used to create television programs for entertainment purposes. Thus, they are influencing public voyeurism. Programs like ＂Big Daddy＂, ＂Big Brother＂, and ＂Big Boss＂ are disclosing personal activities of the characters through hidden cameras. They are considered as soft-core pornography on mainstream television and satellite channels.

Local inhomogeneity in totally asymmetric simple exclusion processes with different hopping rates

Local inhomogeneity in totally asymmetric simple exclusion processes （TASEPs） with different hopping rates was studied. Many biological and chemical phenomena can be described by these non-equilibrium processes. A simple approximate theory and extensive Monte Carlo computer simulations were used to calculate the steady-state phase diagrams and bulk densities. It is found that the phase diagram for local inhomogeneity in TASEP with different hopping rates p is qualitatively similar to homogeneous models. Interestingly, there is a saturation point pair （a＊, fl＊） for the system, which is decided by parameters p and q. There are three stationary phases in the system, when parameter p is fixed （i.e., p=0.8）, with the increase of the parameter q, the region of LD/LD and HD/HD phase increases and the HD/LD is the only phase which the region shrinks. The analytical results are in good agreement with simulations.

Phase Transition and Phonon Spectrum of Zinc-Blende Structure ZnX (X=S, Se,Te)

Calculations have been performed to investigate the pressure-induced solid-solid phase transitions and the mechanical stability for three zinc-blende II-VI semiconductor compounds： ZnS, ZnSe, ZnTe by ab initio plane-wave pseudopotential density functional theory （DFT）. Using the generalized gradient approximation （GGA） for exchange and correlation in the scheme of Perdew-Wang 1991 （P Wgl ）, the ground state properties and equation of state are obtained, which are well consistent with the experimental data available and other calculations. On the basis of the forth-order Birch-Murnaghan equation of states, the transition pressures Pt are determined through the analysis of enthalpy variation with pressure. A linear-response approach is used to calculate the frequencies of the phonon dispersion. Finally, by the calculations of phonon frequencies, some thermodynamic properties such as the vibrational contribution to the Helmholtz free energy （F）, enthedpy （H）, entropy （S）, and the heat capacity （Cv ） are also successfully obtained.

Coastal Sea Water Quality of Nha Trang Bay, Khanh Hoa, Viet Nam

Nha Trang Bay is famous not only because of its beauty, but also of the biodiversity values, especially coral reefs. Thus, the sea water quality monitoring systems are necessary for effective and available managements to protect the ecosystems and for sustainable development. There have been several monitoring systems here but they have been done separately and unconnectedly. This research was done to take an overview and access the status and changes of water quality from 2007-2014. The data obtained rainy seasons over the years showed a quite good environment here. The environment changes were also monitored and there were some changes between seasons and over years, decreasing, increasing, or unobvious trends. However, the difference was not so much; and there was not the sign of environmental degradation in the bay from 2007 to 2014. Besides, the stoichiometric nutrients limitations were initially assessed. Since Si ratios here were always higher compared to N and P, there was not increased potential for non-diatom algal blooms. Together with the recorded nutrients concentration data, it can be said that there was no evidence of eutrophication in the bay. Although there was partial contamination of some parameters at few moments, the sea water quality of Nha Trang bay was still in a good condition （according to Vietnamese and ASEAN criteria）.
