本研究通过3个实验探索了初中生认知控制对替代性攻击行为的影响以及认知控制影响替代性攻击行为的激惹和触发情境边界条件。实验1考察了一般性认知控制对替代性攻击行为的影响,结果发现一般性认知控制不能有效降低替代性攻击行为的攻击比例。实验2探讨了特异性认知控制对替代性攻击行为的有效抑制作用,结果发现无论在高激惹情境还是低激惹情境,主动控制和反应性控制启动条件下的替代性攻击行为均显著低于基线水平。实验3则探究了特异性认知控制抑制替代性攻击行为的激惹和触发情境边界条件,结果发现特异性认知控制、激惹情境、触发情境三者的交互作用显著,激惹和触发情境能够有效调节特异性认知控制对替代性攻击行为的影响。而且,在高激惹高触发和高激惹低触发情境下,主动性控制减基线的攻击比例显著高于反应性控制减基线,但在低激惹高触发和低激惹低触发情境下主动性控制减基线的攻击比例与反应性控制减基线不存在显著差异。此外,高激惹高触发情境下主动性控制减基线的攻击比例是所有条件下最高的。以上结果说明,特异性认知控制能够有效抑制初中生的替代性攻击行为,其中主动性控制的情境边界出现在高激惹高触发情境。

A self\|assembled monolayer film(SAM) of ruthenium phthalocyanine(RuPc) fabricated on a silver substrate premodified with an SAM of terephthalonitrile(TPN) was studied by means of surface\|enhanced Raman scattering(SERS) and ultraviolet\|visible(UV\|Vis) spectroscopies. TPN was used as a ligand to link RuPc since it can not only modify the silver substrate but also deliver the nitrile groups protruding from the silver surface. Therefore,we can explore the relationship between the structure and the orientation of RuPc and the TPN\|modified substrate. The UV\|Vis spectra indicate a strong interaction between RuPc and TPN in the composite film. The result is further confirmed by the SERS spectra of RuPc\|TPN SAM,in which the vibrational bands arising from both the RuPc and TPN moieties appear clearly,indicating that the RuPc is successfully assembled on the TPN film.

马克思“机器论片段”重点论述了机器体系的产生及其在社会生产中的应用所引起的劳动资料技术化、一般智力对象化、固定资本扩大化、人机关系异化等一系列深刻变革。数字技术具有物质技术与社会历史双重属性,其一方面作为人造的“物体系”,克服与弥补人类自身劳动力的不足,另一方面作为生产关系与资本权力的物性表达。数字技术的广泛应用导致工业时代的“机器悖论”演化为数字时代的“智能悖论”,集中表现为“劳动悖论”“时间悖论”与“解放悖论”。马克思“机器论片段”的机器技术思想对我们在数字时代审思数字技术,探索扬弃技术的权力与宰制,消解人与技术的异化关系,使技术真正摆脱压迫、剥削人的工具地位,成为提高劳动生产率,缩短必要劳动时间和增加自由支配时间,促进人类劳动解放与自由全面发展的现实路径依然具有理论与实践价值。
