随着智能技术的飞速发展,智能体、动植物、基础设施及生态环境等均被赋予了前所未有的可对话性与能动性。“跨生命”与“跨物种”的互动已成为传播学研究不可回避的议题。本文引入哈拉维的“同伴物种”理论,采用“非拟人化”和“非客体化”的“物种”视角来审视人工智能,从关系性存在、摄受共生及文化技术交织等多重维度剖析人-AI交往的复杂性。作为新物种的人工智能,在依附与互利、演替与突变、兼容与竞争的过程中,与人类建立了紧密的同伴关系,这就要求我们走出人类世,建立异类接合、互构共成、多物种共生的人-AI交往观,迎接即将到来的跨物种、跨生命的新交往模式。

为探究温度和振动强度联合胁迫在有水保活运输过程中对花鲈组织损伤及生化指标的影响，本研究以20和12°C的运输温度以及0、20和50 r/min的振动强度为变量，设置6个实验组，模拟运输48 h后，测定氧化应激、组织损伤和免疫反应等变化。结果显示：(1)温度对花鲈存活率的影响大于振动强度。运输24 h后，20°C的运输组，0、20、50r/min的存活率分别为72.70%、62.50%和18.2%；而12°C各运输组存活率均为100%。(2)不同温度下各指标变化趋势差异明显。在20°C的运输条件下，过氧化氢酶(CAT)、谷胱甘肽-S-转移酶(GST)、谷丙转氨酶(ALT)、谷草转氨酶(AST)、酸性磷酸酶(ACP)、碱性磷酸酶(AKP)、溶菌酶(LZM)活性和丙二醛(MDA)含量随着运输时间增加而升高，超氧化物歧化酶(SOD)和免疫球蛋白(IgM)含量随运输时间增加呈现先升高后下降的趋势，血糖(GLU)含量随着运输时间增加而下降。在12°C的运输温度下，CAT、MDA、ALT、AST、LZM呈现先上升后下降的趋势，SOD、GST、GLU、IgM活性呈现先下降后上升的趋势。20°C和50 r/min的运输组，SOD最高活性达0.64 U/mg prot，而12°C和50 r/min的运输组最高值仅有0.37 U/mg prot。研究表明，花鲈保活运输过程中应采用12°C的低温运输并尽量减少运输振动频率。本研究探索了温度和振动强度联合胁迫对海水鱼类组织损伤及生化指标的影响。研究结果可为花鲈短途运输提供参考依据。

精神疾患书写常被用来研究威廉·福克纳的作品,譬如《喧哗与骚动》中个体的隐匿式残损等,这是一种基于病态性考察并兼具批判性的文化追溯。在小说里,疾患表象下倒错的声闻形感知具有鲜明的历史文化意蕴。感觉障碍的昆丁沦为大家族展演的病态产物,从忧郁的症候走向认知的失能,直至“卡夫卡式的个人判决型自杀”,隐喻旧南方秩序的残败与消亡。然而,被忧郁情状控制的昆丁同时生发了一种“向死而生”的潜能,清醒的“自杀”抹去了“过去”的最后一点灵晕,预示着美国南方新秩序的诞生。

本研究结合隐形劳动、技术女性主义理论资源,探讨数字化家务为何被塑造成女性的任务。数字技术与智能设备让家务劳动摆脱了空间的束缚,呈现出线上化、灵活化、去身体化的新特征,但技术的中介性与劳动的离身性也将家务转化为一种隐形劳动。以手机为对象的手指操作与界面劳动隐匿了劳动过程,以微信群为中介的沟通任务因文字化、私人化而导致情感劳动“不可见”。数字化家务增加了女性家务劳动与情感劳动的复杂程度,塑造了一种随时在线的劳动状态。技术与平台的宣传共谋、家庭成员/两性之间的协商互动构建了数字家务以女性为主导的氛围。人工智能技术并非仙女棒,而是与看不见的家务合谋共同塑造出了数字时代的新“田螺姑娘”。
