冲动控制(impulsivity control)是情绪调节的一个重要成分,也是执行控制(executive control)的重要成分。行为研究表明(Hoaken & Shaughnessy,2003),攻击行为青少年的冲动控制能力差,情绪调节能力差。这种冲动控制、情绪调节能力的不足,是否有一定神经基础?需要研究的支持。通过go/no-go任务研究表明(Gehring,Willoughby,2002;Pailing,Segalowitz,2002;Ciesielski,Harris,2004),抑制性负波N2和错误相关负波ern(Ne)与冲动控制密切联系,是关联情绪调节的两个重要成分。本研究运用事件相关电位(ERP)的方法和go/no-go研究范式,以具有高身体攻击行为或暴力

Chinese Science Bulletin 2001年第S1期46卷 90-96,125页

The coast of southern Hainan Island is characterized by wide sandy embayments, which consist of ( i) drowned valleys bounded by steep bedrock hills and only locally receiving sediments, and embayments of various dimensions covered either by (ii) alluvial-deltaic deposits or by (iii) sands of coastal beach ridges/barriers and associated elongated lagoons. During the late Tertiary-Pleistocene the area has experienced isostatic and eustatic movements associated with neotectonics and climatic changes. Such history isrecorded in terraces at various altitudes (SO, 40, 20 m asl) and sequences of coastal sand ridges/baymouth bars. The Holocene variations in sea level and climate are recorded in the dated coastal ridges, coral reef and beachrock. Conditions suitable for reef development started about 8000 a BP. The GPR profiles also show that the internal structures of the sand ridges have composite nature being formed by several superimposed secondary ridges.

错误加工是个体不断优化行为表现并适应环境以实现目标行为的重要加工机制。以往的研究发现,动机会对个体的错误加工造成影响。本文总结了错误加工的机制以及动机对错误加工的影响。错误加工主要有两个ERP成分,分别是错误相关负波(ern)和错误相关正波(Pe)。研究表明动机对错误加工的ern和Pe都有影响。这可能是因为动机加强了错误与正确行为之间的冲突并且增加了对错误的注意力。未来的研究可以探讨在积极和消极的混合动机下的错误加工,以及对意识到和未意识到错误的影响。

The dynamic characteristic of complex network failure and recovery is one of the main research topics in complex networks. Real world systems such as traffic jams and Internet recovery could be described by the complex network theory. We propose a model to study the recovery process in complex networks. Two different recovery mechanisms are considered in three kinds of networks： external recovery and internal recovery. By simulating the process of the nodes recovery in networks, it is found that the system exhibits the feature of first-order phase transition only when the external recovery is considered. Internal recovery cannot induce such a kind of transitions. As external recovery and internal recovery coexist on networks, the systems will retain the most efficient part of external recovery and internal recovery. Meanwhile, a hysteresis could be observed when increasing or decreasing the failure probability. Finally, a largest degree node protection strategy is proposed for improving the robustness of networks.

We investigate the collective dynamics of network-organized identical excitable nodes. We theoretically analyze the stability of the rest state and propose that there are two different transition paths： the stationary path and the oscillatory path. We find that, although the onset of collective dynamics strongly depend on the network topology, the local dynamics and how local nodes interact with each other decide the transition path and the involved bifurcation.

个体决策总是伴随着信息筛选和聚焦的过程。以往针对信息数量影响风险决策的研究多是基于建模和优化,较少有学者从认知过程去探索信息对决策的影响。本研究设计了一个掩牌博弈游戏,利用事件相关电位技术(ERPs),比较了不确定情景下,个体在信息过滤前后的决策行为及脑电差异。行为数据显示,与信息过滤前相比,决策信息过滤后,个体的风险决策参与率更低;脑电结果表明,信息过滤后的决策,引发了个体更大的P2以及ern振幅。上述结果表明,个体在不同的情境下,其信息处理和决策过程存在显著的差异。在信息数量比较多,并且时间短的情况下,决策者更倾向于调用启发式决策模式;而信息过滤后,信息量减少,信息属性更加明确,而且时间相对来说比较充裕,大脑会启动补偿式决策模式,去调用更多的认知资源来分析信息,此时,个体感知到的风险变大,行为会更加谨慎。

为了对ERS钢桥面铺装体系的实际使用效果进行验证,本研究以嘉绍大桥项目为依托,采用路面加速加载系统对钢桥面铺装层的长期使用性能以及极端条件下的路用性能进行试验研究。试验发现,ERS和ern两种结构轴载作用次数达205万次时,平均车辙深度增长的绝对值均不超过5 mm;试验加载次数超过130万次以后,两种桥面铺装结构基本不渗水,其抗滑性能也趋于稳定;加载次数超过80万次以后,铺装结构内部材料出现了疲劳损伤,弯拉应变出现明显增长,且横向最大拉应力大于纵向最大拉应力。而在高温湿热极端条件下,ern结构在轴载作用次数达6万次时,超薄磨耗层开始出现推移剥落;ERS结构在轴载作用次数超过9万次后,SMA结构层迅速破坏。结果表明,ERS和ern两种结构在自然条件下均未出现开裂或破损,具有优良的抗车辙性能;而在极端条件下,这两种结构都出现明显的滑移剪切破坏。相反,热固性的树脂沥青材料在极端条件下表现出了极佳的高温稳定性能,但其抗开裂性能有待进一步研究。横向拉应力引起的纵向裂缝是造成铺装层开裂破坏的主要原因,因此应将横向最大拉应力作为铺装层设计的重要控制指标。
