【目的/意义】随着网络科技的不断进步,官方主流媒体的舆论压力与日俱增,通过对2017年的热点"江歌事件"进行分析,结合议程设置探讨其中网络群体出现的极化现象,了解其深层次内涵,对今后媒体的舆论引导提供借鉴意义。【方法/过程】利用微博数据进行内容分析,并结合本文分析的方法以及舆论环境和相关的理论对整个事件发展进行剖析。【结果/结论】可以得出,媒介议程对受众议程存在较大影响并呈反相关系,议题驱动和较低的导向需求是议程失效的原因,单一属性的议程会将受众偏激的态度引向极化。

The incidence of dengue in Malaysia has shown an increasing trend since the year 2000. Vector control is the primary approach for dengue control in Malaysia. There is an urgent need for new or modified approaches such as the residual spraying on the outer walls that can potentially last long enough to control the Aedes population, particularly in the outbreak-prone areas. In this field study, we conducted outdoor residual spraying (ORS) using a newly formulated polymer-enhanced suspension concentrate (SC-PE) of deltamethrin. The objectives of this study were to evaluate the efficacy of ORS using deltamethrin SC-PE and its effect on wild Aedes populations and to assess its residual bio-efficacy on painted cement walls against the pyrethroid-susceptible strains of laboratory-reared Aedes mosquitoes. Three rounds of spraying in a four-month cycle were conducted between 2014 and 2015 in four residential areas (low-rise and high-rise housing types) in Hulu Langat, Selangor. The bio-efficacy of the insecticide was evaluated by assessing its impact on vector population using ovitrap surveillance. Standard WHO wall deposit bioassay was adapted to determine bio-efficacy of deltamethrin, i.e. post 30 min knockdown and post 24 h mortality after exposure. During the treatment period, we observed significant reductions in the population of Ae. albopictus in the sprayed low-rise housing in both semi-indoor and outdoor environments, while in the high-rise housing, there was also a significant decline in Ae. aegypti population in the semi-indoor environment. The evaluation of the residual bio-efficacy of deltamethrin SC-PE against laboratory-reared Aedes mosquitoes showed that the insecticide lasted longer in the high-rise housing compared to the low-rise housing with >80% mortality achieved continuously for 16 weeks. We provide initial evidence on residual efficacy of deltamethrin SC-PE in reducing Aedes population size in the low-rise and high-rise housing. Our results showed tha

利用DPPH自由基清除能力与总还原能力分析,对新疆产细虫草发酵菌丝体的菌醇提物(OGPDC)的抗氧化能力进行测定.MTT分析OGPDC对肺癌A549细胞增殖的抑制作用.抗氧化结果表明OGPDC具有较好的清除DPPH自由基及总还原能力,且清除自由基和总还原能力随着醇提物浓度的升高,逐渐增强,清除DPPH自由基的IC50值为1.952 mg/mL;MTT结果显示OGPDC对肺癌A549细胞增殖有一定的抑制作用,随着浓度提高而增强,处理48 h时药物的IC50值为10.87μg/mL.另外,利用用流式细胞仪检测OGPDC作用48 h后肺癌A549细胞周期变化及凋亡率,其总凋亡率高于仅加培养液的对照组,最高总凋亡率为34.77%,使A549细胞周期阻滞在G0/G1期.结果表明新疆产细虫草菌醇提物(OGPDC)在一定的浓度范围内具有抗氧化及抗癌活性,暗示新疆产细虫草发酵菌丝体具有重要的开发利用价值.

现阶段,依照绿色投资原则(GIP),中国特别重视“一带一路”倡议下项目的可持续性,重点强调“可持续发展”和“可持续债务”。绿色投资原则与“环境、社会和治理投资”(ESG investment)①相关联,“环境、社会和治理投资”是当今社会使用越来越频繁的术语,作者将新技术(Technology)因素加入其中,成为“ESTG”,表示既要考虑环境、社会和治理方面的因素,又要考虑新技术的作用。这反映了从“单一价值驱动”投资向“多元价值驱动”投资的逐步转变过程,意味着在公司或国家投资时,利润不再是考虑的唯一标准,应综合考虑环境、社会、技术和治理。这种转变强调的是,除了股东之外,还有利益相关者(包括消费者、大众媒体、政府部门、多边组织和地方团体)、环境、社会、技术和治理以及声誉问题。近几年,环境、社会、技术和治理在实践中取得了成功,这将为中国和其他国家有史以来实施的伟大的“一带一路”倡议搭建新的舞台。

试验旨在研究用紫花豌豆部分替代溶剂萃取大豆粉(SBM)和玉米对奶牛瘤胃发酵、营养物质消化率和氮素损失的影响。试验采用重复3×3拉丁方设计,选择6头安有瘤胃瘘管的奶牛,处理1饲喂基础日粮,为对照组;处理2饲喂轧制豌豆日粮(RP):用150g·kg-1轧制干豌豆替代SBM和谷物;处理3饲喂碎豌豆日粮(GP):用150g·kg-1碎豌豆日粮替代SBM和谷物,且豌豆经锤式粉碎机粗糙粉碎。试验结果表明,日粮并不影响瘤胃pH、总体和单一挥发性脂肪酸。RP日粮组的乙酸/丙酸较对照组和GP组高。与对照组相比,GP组瘤胃氨浓度较大。干物质、有机物、氨、中性洗涤纤维和淀粉的表观消化率在对照组和GP组中无差异。但与对照组和GP组相比,RP组的干物质、有机物、氨的表观消化率较低。豌豆本身含氮较SBM更丰富,两者分别为290g·kg-1、135g·kg-1。在氮吸收平衡时,GP组氮素损失较对照组高。与对照组相比,饲喂豌豆日粮可减少奶牛产奶量主要由于干物质的吸收减少。试验表明,在奶牛日粮中添加150g·kg-1磨碎豌豆,瘤胃中的豌豆蛋白要比SBM蛋白易吸收。日粮中豌豆的粗糙磨碎可以避免降低营养物质的总消化率。
