智能时代劳动工具“类人化”塑造着新的人机分工劳动配置,以人为中心的劳动关系的瓦解促成了人机劳动共同体,人类与智能机器分工与协同的劳动称为第三种劳动。在智能品牌传播业务执行中,人机间并非单方面替代与被替代的竞争关系,而是互惠式增强关系,即人工智能的生产力和效率优势通过人类劳动者与技术间有意识、功能性的协作来实现。在此劳动关系中形成了新的人机劳动形态:提示、审核、修改、提问。互惠式增强关系的形成机制是系统的反身性,它是一种可持续、可反馈的构建动态协调人机关系的能力。品牌传播业务运作流程中存在两种反身能力:日常反身能力与紧急反身能力。基于人机互惠式增强关系,有效释放第三种劳动的生产力及提升品牌传播价值,需要围绕如何建构有效的协同式增强关系展开,即顺应人机共生趋势,“功能互补”与“价值匹配”兼顾,警惕“逆分工”削弱人机系统的反身能力。

烟气含氧量的精准控制对城市固废焚烧处理厂的稳定高效运行具有重要意义.然而,由于固废焚烧过程固有的非线性和不确定性,难以实现烟气含氧量的有效控制.为此,文中提出一种数据驱动的城市固废焚烧过程烟气含氧量预测控制方法.首先,设计了一种基于自组织长短期记忆(SOLSTM)网络的预测模型,结合神经元活跃度与显著性动态调整隐含层结构,提高了烟气含氧量的预测精度.其次,为了保证优化效率,利用梯度下降法求解控制律.此外,基于李雅普诺夫理论分析了所提方法的稳定性,确保控制器在实际应用过程中的可靠性.最后,基于实际工业数据对所提出的控制方法进行了验证,结果表明,提出的数据驱动预测控制方法能实现对城市固废焚烧过程烟气含氧量的稳定高效控制.

目的了解台州地区市售蔬菜中铅、镉、总汞、总砷、总铬、锰、镍、铝、铜的污染状况并进行人群健康风险评估。方法按照国家相关标准要求对2019—2023年采集的四类市售蔬菜样品中金属及类金属进行含量检测，采用单因子污染指数法（Pi）、内梅罗综合污染指数法（PM）进行污染评价，采用目标危害系数法（THQ）、总体目标危害系数法（TTHQ）进行人群健康风险评价。结果共采集四类蔬菜419份，铜与锰的检出率最高，均为100.0%,其余由高到低依次为镍（89.17%）>铝（87.26%）>镉（85.20%）>总砷（52.03%）>铅（35.32%）>铬（30.79%）>总汞（2.39%）。镉总体超标率为2.63%,超标样本集中在根茎类蔬菜，其余元素均未超标。不同类别蔬菜中铅、镉、总汞、总砷、总铬的Pi与PM均≤0.7;成人摄入四类蔬菜的TTHQ值均1.0。结论台州市市售四类蔬菜中9种金属与类金属总体污染水平较低，居民经蔬菜摄入这9种金属与类金属健康风险水平可接受，但儿童摄入根茎类与叶菜类蔬菜可能会对人体健康产生负面影响。
