找准舆论监督落点的媒体意识——以金华广电总台《正风问效》栏目的实践为例

舆论监督以＂科学监督、有序监督和依法监督＂为内在支撑,以其强大的调查力、实证力、说服力、批评力取得了社会认同,建设性舆论监督栏目正成为代表公众发声、监督权力运行的媒体力量。而舆论监督的力度,来自层层剥茧、透过表象看本质的认知力和调查力,更需要找准建设性监督的落点,也就是新闻的立足点和批评的发力点。但目前,诸多舆论监督报道在＂方向感、落脚点和逻辑性＂上存在不足,新闻止于表象,

答《文学报·散文诗研究》主编箫风问

箫风:李耕老师您好!非常感谢您再次带病接受我的访谈。上次访谈时重点聊的是郭风与散文诗的话题,今天想请您谈谈自己的散文诗创作情况。请问您的散文诗处女作何时发表的?"李耕"这个笔名是何时启用的?有什么寓意?李耕:我原名罗的,曾用过的笔名有巴岸、也罗、白烟、于冷、丁犁、魏冷等。1947年发表随笔《文学是严肃的工作》,始以李耕为己之笔名,沿用至今。李耕并非是"犁耕"的谐音。抚养我至10岁逝世的祖母姓李,而祖母给我童年留下的不泯失的印象是宽厚、悲悯、仁慈、勤劳、简朴,并助做杂工的祖父在半饥饿中将家撑了起来。这是我的"李"姓(纪念祖母)的由来。"耕"之与我,是感情沉湎于"草根"、"泥土"的已难以"解构"的选择,也是"简朴"或甘于面对艰困的选择。我自篆过一方印章"牛",便是"李耕"的图腾或"耕"的代谓了。在现实生存环境中,自己终于成为"牛",这是巧合,也是个性的必然。

最强大的是时间

多少热闹,都熬不过一个时间:有一天。有一天,炙手可热的,突然黯淡了;有一天,阿谀恃宠的,突然失势了;有一天,春风得意的,突然落魄了;有一天,一直前呼后拥的,突然冷清了;有一天,始终鞍前马后的,突然翻脸不认人了。——人生多少热闹,都在有一天,成了烟云。繁华逝,热闹散,人到苍凉,易被冷眼看。才知道,人生宜淡泊经营,浮华不得,喧嚣不得,更张狂不得。人也只有在大起大落大荣大辱之后,才会活得明白,才会活得老实。

An adaptive pipelining scheme for H.264/AVC CABAC decoder

An adaptive pipelining scheme for H.264/AVC context-based adaptive binary arithmetic coding(CABAC) decoder for high definition(HD) applications is proposed to solve data hazard problems coming from the data dependencies in CABAC decoding process.An efficiency model of CABAC decoding pipeline is derived according to the analysis of a common pipeline.Based on that,several adaptive strategies are provided.The pipelining scheme with these strategies can be adaptive to different types of syntax elements(SEs) and the pipeline will not stall during decoding process when these strategies are adopted.In addition,the decoder proposed can fully support H.264/AVC high4:2:2 profile and the experimental results show that the efficiency of decoder is much higher than other architectures with one engine.Taking both performance and cost into consideration,our design makes a good tradeoff compared with other work and it is sufficient for HD real-time decoding.

Chemical characterization and sources of PM2.5 at 12-h resolution in Guiyang, China

The increasing emission of primary and gaseous precursors of secondarily formed atmospheric particulate matter due to continuing industrial development and urbanization are leading to an increased public awareness of environmental issues and human health risks in China. As part of a pilot study, 12-h integrated fine fraction particulate matter （PM2.5） filter samples were collected to chemically characterize and investigate the sources of ambient particulate matter in Guiyang City, Guizhou Province, southwestern China. Results showed that the 12-h integrated PM2.5 concentrations exhibited a daytime average of 51 ± 22 μg m^-3 （mean -4- standard deviation） with a range of 17-128 μg m^-3 and a nighttime average of 55 ± 32 μg m^-3 with a range of 4-186 μg m^-3. The 24-h integrated PM2.5 concentrations varied from 15 to 157 μg m^-3, with amean value of 53 ± 25 μg m^-3, which exceeded the 24-h PM2.5 standard of 35μg m^-3 set by USEPA, but was below the standard of 75 μg m^-3, set by China Ministry of Environmental Protection. Energy-dispersive X-ray fluorescence spectrometry （XRF） was applied to determine PM2.5 chemical element concentrations. The order of concentrations of heavy metals in PM2.5 were iron （Fe） 〉 zinc （Zn） 〉 manganese （Mn） 〉 lead （Pb） 〉 arsenic （As）〉 chromium （Cr）. The total concentration of 18 chemical elements was 13 ± 2 μg m^-3, accounting for 25% in PM2.5, which is comparable to other major cities in China, but much higher than cities outside of China.

The Anne Frank House in Amsterdam＂ A Museum and Literary Landscape Goes Virtual Reality

The Anne Frank House, site of Anne Frank＇s place of hiding 1942-1944, has become a leading tourist attraction in Amsterdam and among heritage sites of the Holocaust. This paper reviews the historical context of the political events from 1933 to 1945, the circumstances for the betrayal, and arrest of the group in hiding, the saving of Anne Frank＇s diary and its publication after her death at the Bergen-Belsen concentration camp in March 1945. Further, the paper reconstructs the beginnings of the heritage site as a small museum at 263 Prinsengracht in 1960 as well as the management issues and capacity problems that led to a larger museum complex including an educational center in 1999. During the years of 2007-2010, when the annual visitation of the museum surpassed one million, the Anne Frank House decided to introduce a high quality 3D version of the Secret Annex on the Intemet. In the final part of the paper, trends in museum management and the more frequent uses of a digital documentation of heritages sites are reviewed.

Development and psychometric assessment of the public health emergency risk perception scale:Under the outbreak of COVID-19

Objective:Correctly understanding and evaluating the level of public risk perception toward public health emergencies not only helps experts and decision-makers understand the public’s preventative health behaviors to these emergencies but also enhances their risk information communication with the public.The aim of this study was to develop a risk perception scale for public health emergencies and test its validity and reliability during the coronavirus disease 2019(COVID-19)pandemic.Methods:Guided by the theoretical model of risk perception,an initial scale was generated through literature review,group meetings,resident interviews,and expert consultation.A pretest and item screening were then conducted to develop a formal risk perception scale for public health emergencies.Finally,the reliability and validity of the scale were validated through a questionnaire survey of 504 Chinese adults.Results:The final scale had 9 items.The content validity index of the scale was 0.968,and the content validity index of individual items ranged from 0.83 to 1.00.Three common factors,dread risk perception,severe risk perception,and unknown risk perception,were extracted for exploratory factor analysis,and together they explained 66.26%of the variance in the score.Confirmatory factor analysis showed that the model had a satisfactory fit,whereχ^(2)/df=1.384,the goodness-of-fit index(GFI)=0.989,root mean square error of approximation(RMSEA)=0.028,root mean square residual(RMR)=0.018,comparative fit index(CFI)=0.995,normed fit index(NFI)=0.982,and non-normed fit index(NNFI)=0.990.The correlations between dimensions ranged from 0.306 to 0.483(P<0.01).Cronbach’s a was 0.793 for the total scale and ranged between 0.687 and 0.801 for the individual dimensions.The split-half coefficient was 0.861 for the total scale and ranged from 0.727 to 0.856 for induvial dimensions.The test-retest coefficient was 0.846 for the total scale and ranged from 0.843 to 0.868 for induvial dimensions.Conclusion:The developed scale for the risk perception of public health emergencies showed acceptable levels of reliability and validity,suggesting that it is suitable for evaluating residents’risk perception of public health emergencies.

Variance Reduction Technique for Estimating Value-at-Risk based on the Cross - Entropy

Value-at-Risk （VaR） estimation via Monte Carlo （MC） simulation is studied here. The variance reduction technique is proposed in order to speed up MC algorithm. The algorithm for estimating the probability of high portfolio losses （more general risk measure） based on the Cross - Entropy importance sampling is developed. This algorithm can easily be applied in any light- or heavy-tailed case without an extra adaptation. Besides, it does not loose in the performance in comparison to other known methods. A numerical study in both cases is performed and the variance reduction rate is compared with other known methods. The problem of VaR estimation using procedures for estimating the probability of high portfolio losses is also discussed.

Aerodynamic problems of cable-stayed bridges spanning over one thousand meters

The elongating of cable-stayed bridge brings a series of aerodynamic problems. First of all,geometric nonlinear effect of extreme long cable is much more significant for cable-stayed bridge spanning over one thousand meters. Lateral static wind load will generate additional displacement of long cables,which causes the decrease of supporting rigidity of the whole bridge and the change of dynamic properties. Wind load,being the controlling load in the design of cable-stayed bridge,is a critical problem and needs to be solved. Meanwhile,research on suitable system between pylon and deck indicates fixed-fixed connection system is an effective way for improvement performance of cable-stayed bridges under longitudinal wind load. In order to obtain aerodynamic parameters of cable-stayed bridge spanning over one thousand meters,identification method for flutter derivatives of full bridge aero-elastic model is developed in this paper. Furthermore,vortex induced vibration and Reynolds number effect are detailed discussed.

Causes of Buildings＇ Abandonment in the Years 1960-1990

When a relatively new building is not being fully utilized, there must have existed, at one time, a change in its initial conditions. The aim of this research is to study the changes in the initial conditions which cause buildings to be underutilized and analyze whether the demolition was justified. Causes can be found in problems due to the building＇s management, as the owners make the main decisions concerning the buildings. Additionally problems are due to the location where the building is constructed because site conditions changes a lot in one generation. The use of the building can also be a cause of abandonment as the original use can end before the lifespan of the building. Architectural style can be dated as fashions and styles change rapidly. Finally, causes can be in the physical condition of the buildings： structure, construction, installations and adherence to current regulations. In this article, the authors provide guidelines demonstrating how buildings of a past generation which were initially considered obsolete, can be properly reused.

Multidimensional Utopia： Chinese Logic of the Future Imagination of the Three-body Problem

The greatest charm of science fiction is not the artistic imagination, but the scientific imagination.Liu Cixin＇s the Three-body Problem as a Chinese science fiction novel, reflected Chinese writer how to think science and technology and its possible future of mankind＇s imagination. This novel contained ＂Deconstruction＂ Utopia, ＂Transcendence＂ dystopia and ＂Composited＂ Heterotopias, Which fully demonstrated singularity politics＇s great ideological tension between post modernity thinking of in this or that and typical Chinese style doctrine and dialectics.

Global Environmental Change and National Security of China

The concept of security has been redefined since the 1990s. As one of the important factors threatening human security, global environmental change has become a new challenge to the national security and social development. The national security problems caused by global environmental change, on one hand, are closely related to the global environmental problems, and, on the other hand, are manifested in the conflicts of international affairs. The global environmental change severely challenges the future development of China. When it comes to the study on human dimensions of global environmental change in China, much more attention should be paid to issues of important environmental change that may have great impacts on the national security of China, to the scientific assessment of the vulnerabilities of the natural and socialeconomic system of China to the impacts of global environmental change, and to the active establishment of the national risk management system, in which global environmental change should be included, so as to make contribution to sustainable development and construction of harmonious society of China.

The effect of exposure of iron and its oxide dust to the body

Iron overload is closely related to many diseases. Iron overload is a risk factor that triggers a series of health problems. The toxicity of iron is that iron can catalyze the formation of oxygen free radicals and can be used as a nutrient necessary for the growth of microorganisms and tumor cells. The sensitivity of human cells to iron toxicity varies widely. Causes of iron overload include genetic factors, behavioral factors and environmental factors. With the rapid development of modem industry, iron and its compound dust distribution industry and the increasingly widespread, in the iron pigment production, mechanical casting, iron ore mining and iron smelting operations will produce a lot of iron and its compound dust, Its impact on the human body has been of concern. Long-term exposure to iron and its compounds can cause different degrees of damage to the respiratory system, resulting in iron in vivo disorder. The relationship between iron metabolism and lung injury has also begun to be concerned, and maintaining iron homeostasis is important for lung injury and its protection.
