企业热点事件网络舆情生成影响因素研究

围绕科技力量和科技竞争的企业网络舆情时有发生,研究企业热点事件网络舆情生成的影响因素及对策,对丰富舆情治理理论和支持舆情调适具有重要意义。本研究以孟晚舟所关联的企业热点事件网络舆情为例,利用扎根理论对5377条新浪微博在线评论进行分析,经过开放式编码和主轴编码获取网络舆情生成的影响因素,主要包括主观因素(公众因素)、客观因素(政治因素、企业因素、媒体因素等),再进行选择性编码,结合社会认知理论,分析主客观因素互动并作用于公众发表评论行为的路径及机理。通过这两个维度的深入分析,有针对性地提出引导网络舆情生成的对策,为企业热点事件网络舆情引导与调适实践提供决策参考。

New Technology for High Efficient Recovery of Precious Metals Six-component Alloy Wastes

Aimed at high content of valuable metals, complicated composition, difficult to separation of precious metals six component alloy wastes, the present paper proposed a new technology of high efficient separation and purification. Using fragmentation technology realizes fast dissolution of palladium, silver, copper and zinc in the wastes, and high efficient and complete separation of them from gold and platinum; using evaporation thermal decomposition technology of mixed solution produced by nitric acid dissolving palladium, silver, copper and zinc, complete and high efficient separation of silver from palladium was realized; by control of solution acidity, using hydrazine reduction method, high efficient and complete separation of gold from platinum was realized. Using this new technology, the recovery rates of palladium and silver are above 99%, and gold and platinum above 98%, the grade of pure metals are above 99.95%.

平台事件网络舆情传播的影响因素与治理策略研究:基于WSR的扎根分析

认识平台事件网络舆情的影响因素对平台去中心化与舆情治理具有重要的理论和现实意义。本研究以滴滴网约车平台舆情事件为例,从滴滴出行APP与微博中采集大量用户评论,选取1393条有效在线评论,采用扎根理论进行分析,即通过开放编码和主轴编码获取影响平台事件网络舆情传播的因素。基于物理-事理-人理(WSR)方法论,将相关影响因素纳入物理因素、事理因素和人理因素三个核心范畴中,并提出平台事件网络舆情的治理对策。本研究不仅可以丰富平台事件网络舆情传播影响因素理论框架,也为平台事件网络舆情治理提供方法参考。
