量子阱光电子开关器件(一)

量子阱半导体结构可使诸如光调制器和开关等光电子器件做得更小、更快、效率更高。它所具有的逻辑特性使其在并行高速互连的电子集成电路的集成度上具有良好的潜力。光电子器件能采用波导,也能采用二维并行阵列制作。其集成规模可达2048个单元,可工作的光逻辑和存贮器件的阵列得以实现及运行,所有单元都可由自由空间光(free-space optics)进行外部并行访问。本文概述了量子阱器件的运行机理及其发展前景。     

上海股市周日历效应及长期记忆研究

运用ARMA-GARCH-M、EGARCH-M及FIGARCH-M模型对上海股市A股指数收益率及其波动性的周日历效应进行联合检验;另外还检验了成交量的周日历效应。研究结果表明:(1)风险溢价系数为正值,上海股市的风险传递机制正在发挥作用;(2)股市收益率序列存在显著的周日历效应,并且其异常收益并非来自风险溢价;(3)波动性过程同时存在周日历效应和长期记忆效应;(4)股市交易量同时存在周日历效应和长期记忆效应。最后利用混合分布假说进行了解释,信息可能是周日历效应形成的重要原因。     

论张爱玲《传奇》中的母性批判

张爱玲的小说中出现的母亲大多是有悖于伦理常识的形象,她们构成张爱玲式的"巫母群像",这种母亲形象表现出张爱玲对传统母性观的批判。此倾向的形成,与张爱玲对其母亲的情绪记忆密切相关。同时,张爱玲对母性的批判也暗含着她对女性及人性层面的理性思考与感性期待。     

简论妙悟在思维和意识转移中产生的特性——《沧浪诗话》新释

妙悟是在抽象思维转移为形象思维，有意识转移为无意识的链条上产生的。转移的条件是熟参。如果以往的知识和经验重复千百次之后，就会化为血肉积淀；只要有意识活动，特别是形象思维的有意识活动反复出现，就会积淀成无意识。最重要的无意识活动是前记忆。妙悟的本质特性在转移观点的审视下被揭示出来。     

都市娱乐类传媒言说风格刍议

由于对受众的想象存在着文化低端化定势,当下都市娱乐类传媒大量采用了流行言语和时尚言说方式,形成一种夸张、油腻、生僻化、雷同的言说风格。这种言说风格通过持续而广泛的传播,正在影响着我们的语言规范,其更深的社会文化背景则是公众心态的普遍浮躁和对语言规范的解构。若不注意控制这种言语文风,将对语言体系的健康发展产生过多的噪音。     

The Holodomor law and national trauma construction in Ukraine

This article proposes to conceptualize the remembrance of the 1932–33 famine, known as the Holodomor, as cultural trauma construction in Ukraine. This entails the study of how the memory of this devastating historical event became the national collective symbol of suffering with which Ukrainians identify today. Based on Jeffrey Alexander’s concept of cultural trauma, the analysis focuses on the role of political elites and their claim-making regarding the meaning of the famine. Focusing specifically on the 2006 Holodomor law as the main claim of the Ukrainian policy-makers, the article investigates their definition of the historical event, their naming of victims and perpetrators, and their social mediation of famine representations. The article reveals how, through their definition of the Holodomor as genocide, the political elites promoted the understanding that Ukrainians experienced the years of 1932–33 differently from other Soviet nations. The Holodomor law should therefore be seen in the context of Ukrainian nation-building policy, which aims to forge a distinct Ukrainian collective identity.     

论后现代技术的品性和实践

以信息、语言、记忆工业和时间物体为代表的后现代技术,批判现代技术的机械化、商品化、功利化、权力化人类中心主义以及物化和异化带来的各类难以预测的事故和灾难。主张在非祛魅性、多元性、生态性和非决定论的后现代科学基础上,根除"技术官僚主义",推动后现代技术往更加人道、民主、自由、智慧和艺术的方向发展,将技术进一步人性化和真善美一体化,使其真正为新人民和全人类的文明服务。     

Agency of internal transnationalism in social memory

The article examines the limitations of methodological nationalism in the studies of social memory through a case study of memory of Stalinist repression in Belarus. It analyses how various social agencies – national and local activists, religious organisations, and international foundations – use the memory of repression for constructing post‐Soviet Belarusian identity by embedding their national representations in larger transnational frameworks. Drawing on the concept of ‘internal globalisation’, this article develops the idea of ‘internal transnationalism’ that suggests the importance of wider transnational configurations for the definition of nation. Internalized transnationalism does not make a national memory concept less nation‐centred, but it affects the choice of its cultural, political and civilizational framing. In contrast to methodological cosmopolitanism that implies rediscovering of the national as an internalized global, methodological transnationalism emphasizes the multiplicity of co‐existing transnational networks that can be invoked by social actors in their national mnemonic agenda. Using the case of the Kurapaty memorial site the article analyses how multiple framings of memory representations – the Belarusian national memory, liberal anti‐communist memory, contesting memories, such as Polish, Baltic and Jewish – compete and juxtapose in the space of social memory of political repression.     

Does surprise enhance infant memory? Assessing the impact of the encoding context on subsequent object recognition

A discrepancy between what was predicted and what is observed has been linked to increased looking times, changes in brain electrical activity, and increased pupil dilation in infants. These processes associated with heightened attention and readiness to learn might enhance the encoding and memory consolidation of the surprising object, as suggested by both the infant and the adult literature. We therefore investigated whether the presence of surprise during the encoding context enhances subsequent encoding and recognition memory processes for the items that violated infants' expectations. Seventeen-month-olds viewed 20 familiar objects, half of which were labeled correctly, while the other half were mislabeled. Subsequently, infants were presented with a silent recognition memory test where the previously labeled objects appeared along with new images. Pupil dilation was measured, with more dilated pupils indicating (1) surprise during those labeling events where the item was mislabeled and (2) successful retrieval processes during the memory test. Infants responded with more pupil dilation to mislabeling compared to correct labeling. Importantly, despite the presence of a surprise response during mislabeling, infants only differentiated between the previously seen and unseen items at the memory test, offering no evidence that surprise had facilitated the encoding of the mislabeled items.     

Piecewise FARIMA models for long-memory time series

We consider the problem of modelling a long-memory time series using piecewise fractional autoregressive integrated moving average processes. The number as well as the locations of structural break points (BPs) and the parameters of each regime are assumed to be unknown. A four-step procedure is proposed to find out the BPs and to estimate the parameters of each regime. Its effectiveness is shown by Monte Carlo simulations and an application to real traffic data modelling is considered.
