农村家庭认知与响应地震灾害的特点及其家庭际差异——以2007年云南宁洱6.4级地震灾区为例

以2007年云南宁洱6.4级地震灾区为例,通过现场访谈和问卷调查,分析了该地区农村家庭认知与响应地震灾害的特点及其家庭际的差异性。结果表明:当地农村家庭认知与响应地震灾害的水平尚不理想,综合防震减灾能力较弱;家庭对地震灾害知识和防震减灾技能的掌握程度,显著地影响着其在震时及震后的响应行为和态度,其中防震减灾技能的影响更显著;经济收入和教育背景不同的家庭,其地震灾害的认知水平和响应能力也呈现出明显的差异性,其中受教育程度的影响更明显,且可能是最根本的影响因素;家庭人口总数与家庭地震灾害认知与响应的综合能力呈显著的负相关关系,但这种影响也叠加了家庭经济文化因素的影响;对研究区而言,加强防震减灾实用技能和震时如何有效应对地震影响方面的教育,具有更重要的现实意义。     

安全生产监管系统化和信息化探讨

青岛市南区安全生产监督管理局按照青岛市委市政府建立健全“党委领导、政府监管、行业管理、企业负责、社会监督”安全生产格局的要求，全面推行安全生产网格化监管模式。安全生产网格化监管模式的建立和运行，有效解决了安全生产监管信息的采集、传递与处理不及时的问题，变被动监管为事前预防，变分头管理为政府合力，变粗放式管理为精细化运作，进一步强化了政府部门的监管责任，形成了科学、高效、规范的风险管理运行模式。     

CO2 emission driving forces and corresponding mitigation strategies under low-carbon economy mode: evidence from China’s Beijing–Tianjin–Hebei region

On account of the background of China’s “new normal” characterized by slower economic growth, this paper analyses the low-carbon economy status quo in the Beijing–Tianjin–Hebei region and empirically investigates the relationship between carbon dioxide (CO₂) emissions and its various factors for China’s Beijing–Tianjin–Hebei region using panel data econometric technique. We find evidence of existence of Environmental Kuznets Curve. Results also show that economic scale, industrial structure, and urbanization rate are crucial factors to promote CO₂ emissions. However, technological progress, especially the domestic independent research and development, plays a key role in CO₂ emissions abatement. Next, we further analyze the correlation between each subregion and various factors according to Grey Relation Analysis. Thereby, our findings provide important implications for policymakers in air pollution control and CO₂ emissions reduction for this region.

肘部支撑在视频显示终端作业过程中对背部和右手表面肌电影响的Meta分析

本文主要探讨肘部支撑在视频显示终端作业过程中对背部和右手表面肌电的影响。采用Meta分析方法对以往研究资料进行筛检及汇总分析。结果发现：左右侧斜方肌的最大自主收缩百分比（MVC％）分别下降了0．83％（95％CI-1．00％--0．66％）和0．61％（95％CI-0．78％～-0．43％），对于右手食指伸指肌而言，其影响并不具有显著性。可以认为肘部支撑是一种比较简单而且有效的预防措施。     

EFFECT OF SOIL STERILIZATION BY MERCURIC CHLORIDE ON HERBICIDE SORPTION BY SOIL

Microbial inhibitors such as mercuric chloride are frequently used to sterilize soil or soil–water slurries in experimental studies on the fate of xenobiotics in the environment. This study examined the influence of mercuric chloride additions to soil–water slurries on the sorptive behaviour of a phenoxy herbicide (2,4-D) in soil. The results demonstrated that mercuric chloride strongly decreased the capacity of the soil to retain herbicides, and that the interference of mercuric chloride with herbicide sorption increased with increasing soil organic carbon contents. Because of the competitive sorption between mercuric chloride and the phenoxy herbicide, we conclude that mercuric chloride may not be a good soil sterilization procedure for use in xenobiotic fate studies.     

Ionic dye adsorption by zinc oxide nanoparticles

The adsorption behaviour of Basic Red 12, Acid Orange 7 and Acid Blue 1 on zinc oxide nanoparticles (ZNP) has been investigated to understand the physicochemical process involved and to explore the possible use of nanoparticles in the treatment and management of textile waste matter. The dye removal capacity of ZNP towards Basic Red 12, Acid Orange 7 and Acid Blue 1 was found to be 15.64, 6.78 and 6.38 mg g^?1, respectively. The adsorption process was pH dependent and optimum pH values of 9.0, 2.0 and 4.0 were obtained for Basic Red 12, Acid Orange 7 and Acid Blue 1, respectively. Equilibrium was established after 1.0 h for all dyes. Langmuir, Freundlich and Temkin isotherm models were applied to the system. The adsorbent ZNP was characterised using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and Fourier transform infrared (FTIR) techniques. SEM analysis revealed the noticeable nanoporous morphology of the material. The results of FTIR spectroscopy showed that the process is driven by an electrostatic complexation mechanism. XRD studies revealed the nanocrystalline structure of ZNP. BET surface area measurement suggested a high pore volume and large surface area for the adsorbent. The kinetic measurements suggested pseudo-second-order kinetic processes with high regression coefficients and smaller standard error of estimate values and lower residual sum of squares. The thermodynamic measurements suggested that all processes were exothermic and accompanied by negative values for Δ G⁰, Δ S⁰ and Δ H⁰.     

淀山湖浮游植物营养限制因子的研究

通过藻类增长的生物学评价(Nutrient Enrichment Bioassay)研究淀山湖浮游植物生长限制性因子，并采用析因方差分析和事后比较方法分析营养盐（PO^3-₄P、NH₃N、NO^-₃N）对浮游植物生长速度、平均最大现存量和平均最大特定增长率的影响。研究表明：磷对浮游植物生长有明显的促进作用，能提高浮游植物的生长速度和现存量，且促进作用随磷浓度（0.13～0.53 mg/L）的增加而加强，磷是淀山湖浮游植物增长的第一限制性因子；低浓度硝氮（2.91～5.91 mg/L）对浮游植物生长有微小的促进作用，但高浓度（5.91～8.91 mg/L）的硝氮表现出抑制作用；氨氮对浮游植物生长有抑制作用，并随浓度（1.25～7.25 mg/L）的增加而增大；添加磷+硝氮能明显促进浮游植物生长，磷与硝氮之间存在一定的交互作用.
