情绪语音调节面孔表情的识别：ERP证据

采用事件相关电位（ERP）技术考察了情绪语音影响面孔表情识别的时间进程。通过设置效价一致或不一致的“语音-面孔”对,要求被试判断情绪语音和面孔表情的效价是否一致。行为结果显示,被试对效价一致的“语音-面孔”对的反应更快。ERP结果显示,在70-130ms和220-450ms,不一致条件下的面孔表情比一致条件诱发了更负的波形;在450-750ms,不一致条件下的面孔表情比一致条件诱发更正的后正成分。说明情绪语音对面孔表情识别的多个阶段产生了跨通道影响。     

“有”、“无”之辨——《老子》第一章再读解

<正>《老子》第一章是老子"道"论的总纲,也可视为整部《老子》的眼目。"道"("恒道")由此而定其所导,"名"("恒名")由此而明其所谓;老子之属意,于此可窥其大略。自《韩非子》以至于汉魏以降,《老子》注疏之众不可胜数,而诸注之意境则大都可从其对于第一章的诠释判别高下。今以帛书《老子》为底本,参酌世传碑、刻、注本,于前贤思绎之未尽处对《老子》第一章再作申解,以期寻取"众眇"所通而我心所契的玄理之门。或有未当,方家正焉。     

Sect‐to‐Church Movement in Globalization: Transforming Pentecostalism and Coastal Intermediaries in Contemporary China

After eight months of itinerant fieldwork across 17 provinces, I elaborate on how the largest Pentecostal group deeply localized in China, the True Jesus Church, has undergone sect‐to‐church movement through interactions among overseas, coastal, and inland churches in globalizing China. A critical intermediary role in this process has been taken by emerging coastal Fujian leaders, who have been successfully reforming not only their churches but also inland counterparts by tactfully utilizing overseas churches as stimuli, resources providers, and legitimizers for the transformation project. The Chinese fever of integration into the world and high status granted to the overseas are keys to smooth away the barriers of the traditionalist old guard. Accordingly, the originally enclosed, anti‐political, sectarian, spirit‐led group has turned more institutionalized, laity‐oriented, text‐based, and welcoming to the government and mainstream Protestantism.     

道家、道教与道学

中国传统文化的主干向称儒、释、道三家(或称三教).自汉魏以来,史家多以"道家"一名混称老、庄之道家与张陵之道教.而"道学"一名既可指称"黄老之学",又为"宋明理学"之代名词.近世以来,学术界引入西学的概念,严格区分"哲学"(Philosophy)的道家与宗教(Reli-gion)的道教.而另外又有以"道学"之名涵盖"道家之学"者.而自19世纪以来,西方汉学界又以英文之Taoism或法文之taoisme统称中国的"道家"与"道教".于是,"道家"、"道教"与"道学"名称的内涵界定与使用范围遂成为学术界多年以来致力探讨的重要问题.本文拟从宗教文化与历史学的角度,通过考察道家思想衍变发展的五个历史阶段,即先秦老子之学与庄子之学,秦汉黄老之学,魏晋玄学,隋唐道教重玄学与宋元道教内丹心性学,来探索"道家"、"道教"与"道学"的内在联系与区别.笔者主张,"道家"一词可作两种不同的理解:一种是狭义的"道家"概念,就是确指自先秦老、庄之学,秦汉黄老之学至魏晋玄学的道家学术流派;另一种是广义的"道家"概念,就是既包括原来先秦自魏晋的"道家"学术流派,也包括东汉以后创立的中国本土宗教"道教".这样,既对现代学科意义上的哲学的"道家"与宗教的"道教"作出了明确的区分,更为重要的是表明了我们尊重自身文化传统的学术立场.至于"道学"的名称,笔者认为无论从历史的层面还是现实的层面都易于与原有的文化现象"理学"发生混淆,为学术长远计虑,使用似宜慎之.     

Age-related enhancement of a protein synthesis-dependent late phase of LTP induced by low frequency paired-pulse stimulation in hippocampus

Protein synthesis-dependent late phase of LTP (L-LTP) is typically induced by repeated high-frequency stimulation (HFS). This form of L-LTP is reduced in the aged animal and is positively correlated with age-related memory loss. Here we report a novel form of protein synthesis-dependent late phase of LTP in the CA1 region of hippocampus induced by a brief 1-Hz paired-pulse stimulation (PP-1 Hz, 1 min). In contrast to L-LTP induced by HFS, the late phase of PP-1 Hz LTP does not exist in young adult animals. Rather, it emerges and becomes enhanced in an age-related way. Thus, in 1.5- to 2-mo-old mice, a brief PP-1 Hz stimulation induces only a short lasting LTP, decaying to baseline in about 90 min. By contrast, PP-1 Hz stimulation induces an enduring and protein synthesis dependent LTP in 12- to 18-mo-old mice. The PP-1 Hz-induced L-LTP is dependent on NMDA receptor activation, requires voltage-dependent calcium channels, and is modulated by dopamine D1/D5 receptors. Because memory ability declines with aging, the age-related enhancement of L-LTP induced by PP-1 Hz stimulation indicates that this form of L-LTP appears to be inversely correlated with memory ability.     

Effects of wrist rest and forearm support on muscle activity

This study examined the effects of wrist rest and forearm support on reducing computer operators' activities using the trapezius, deltoid, biceps brachii, extensor carpi radialis longus, and extensor digitorum. 12 young (M= 25.9 yr., SD= 2.4) men were asked to perform both static and dynamic mouse operations in four conditions, two using a wrist rest and two using a forearm support. Analysis showed that use of the forearm support had a significant effect on reducing the EMG activity in muscles of the trapezius, deltoid, biceps brachii, extensor carpi radialis longus, and extensor digitorum. However, the wrist rest only significantly reduced deltoid and extensor carpi radialis longus activities.     

The Divine Command Theory of Mozi1

In this study, I will examine the famous ‘divine command theory’ of Mozi. Through the discussion of several important chapters of Mozi, including Fayi (law), Tianzhi (the will of heaven), Minggui (knowing the spirits) and Jianai (universal love), I attempt to clarify the arguments of Mozi offered in support of his distinctive ideas of serving heaven, knowing the spirits and loving all. The analysis shows that there are serious problems with his assumptions, hence they fail to support his conclusions as to the heaven–human relationship, and the man–man relationship. That is to say, at least in the texts covered, Mozi did not justify the moral or social relationship in society by appealing to the religious relationship.     

Cortical dynamics of contextually cued attentive visual learning and search: spatial and object evidence accumulation

How do humans use target-predictive contextual information to facilitate visual search? How are consistently paired scenic objects and positions learned and used to more efficiently guide search in familiar scenes? For example, humans can learn that a certain combination of objects may define a context for a kitchen and trigger a more efficient search for a typical object, such as a sink, in that context. The ARTSCENE Search model is developed to illustrate the neural mechanisms of such memory-based context learning and guidance and to explain challenging behavioral data on positive-negative, spatial-object, and local-distant cueing effects during visual search, as well as related neuroanatomical, neurophysiological, and neuroimaging data. The model proposes how global scene layout at a first glance rapidly forms a hypothesis about the target location. This hypothesis is then incrementally refined as a scene is scanned with saccadic eye movements. The model simulates the interactive dynamics of object and spatial contextual cueing and attention in the cortical What and Where streams starting from early visual areas through medial temporal lobe to prefrontal cortex. After learning, model dorsolateral prefrontal cortex (area 46) primes possible target locations in posterior parietal cortex based on goal-modulated percepts of spatial scene gist that are represented in parahippocampal cortex. Model ventral prefrontal cortex (area 47/12) primes possible target identities in inferior temporal cortex based on the history of viewed objects represented in perirhinal cortex.     

TEM observation of oxide scale formed on a Ti–Al–Zr alloy oxidized at 360°C in alkaline steam

Ti–Al–Zr alloy has been oxidized at 360°C in alkaline steam at a pressure of 10.3?±?0.7?MPa. Cross-sectional transmission electron microscopy (TEM) observations indicated that the oxide scale of Ti–Al–Zr alloy was composed of outer and inner subscales, in which the outer layer consists of anatase-TiO₂ and the inner layer a mixture of TiO and Ti₂O. The thickness of the Ti₂O, TiO and anatase-TiO₂ were approximately 50, 100 and 400?nm, respectively. These results were confirmed by X-ray energy dispersive spectrometry (EDS) measurements. The enhanced corrosion of titanium alloys in LiOH solution is attributed to a high hexagonal Ti₂O to tetragonal TiO₂ phase transformation rate induced by the substitution of Li⁺ for Ti⁴⁺ in the oxide layer.
