经颅直流电刺激技术在物质依赖治疗中的应用

物质依赖是一种慢性、复发性脑部疾病, 给个体及社会带来极大损害。研究发现, 经颅直流电刺激(transcranial direct current stimulation, tDCS)可以通过调节背外侧前额叶(dorsolateral prefrontal cortex, DLPFC)脑区的兴奋性降低物质依赖者的渴求, 并改善受损的认知功能。tDCS具有副作用小、操作简便、费用低廉等优点, 因此在物质依赖治疗领域应用前景广泛。未来应考虑确定最佳的刺激参数及刺激位置, 同时考虑物质依赖者的种类及个体差异, 与其他疗法结合使用, 并进一步深入探索tDCS治疗物质依赖的神经机制。     

Effect of Heel Heights on Female Postural Control During Standing on a Dynamic Support Surface With Sinusoidal Oscillations

The authors aimed to investigate female balance or stability control with comparative analysis of the center of pressure trajectory and plantar pressure distribution with different high-heeled shoes while standing on a dynamic surface with multidirectional perturbations. College females with at least 2 years' history of wearing high-heel shoes voluntarily participated in the test with a Novel Pedar insole (Novel, GmBH, Munich, Germany. With heels height increasing, the pressure time integral obviously transfer to the medial forefoot region, with center of pressure trajectory medially deviated significantly, either under anteroposterior or mediolateral perturbations. The passive plantarflexion position of ankle incurred by high heel increased the range of motion in the frontal plane but decreased ankle stability, thus increasing the challenge of body balance maintenance.     

Extending the technology acceptance model to mobile telecommunication innovation: The existence of network externalities

• Consumer acceptance of technological innovations is crucial to marketing new products. According to the most influential model in this area, the Technology Acceptance Model (TAM), perceived usefulness (PU) and perceived ease of use (PEOU) determine users' behavioural intentions to use or purchase a system or product. In the specific context of network externalities, a sense of utility that arises from the number of users (NOU) is considered as important as technology‐specific valuation. This study conducted an empirical survey to examine the effects of TAM and network externalities on the acceptance of Multimedia Messaging Services (MMS), an innovation in the field of mobile telecommunications. The results confirm the effectiveness of the TAM and find that network externalities effect affects users' acceptance to this mobile innovations. Accordingly, the TAM can be applied to predict consumer's acceptance to the mobile telecommunication innovations in the presence of network externalities.

论海德格尔对康德实践哲学的解读

海德格尔对康德实践哲学的解读是他阐释康德哲学的重要组成部分。本文围绕着道德情感、实践理性、实践自由等问题分析了海德格尔在这一方面的解读内容,并且指出海德格尔的解读是定向于存在论的,属于基础存在论筹划,人的存在问题是关注的核心。他力图发掘康德思想中的存在论-生存论的内涵,这反而丧失了原初的伦理学意义。     

超越政治权威的罗马法

自2000年以来,美国学术界展开了关于"最后的帝国"的讨论.该讨论针对的是美国一匡天下的政治现实,它涉及到的问题包括:在一个单极化的世界中,民主与法律这些力求体现程序正义的东西是否具有其适用界限?在相关的探讨中,罗马法及其对现代西方世界的影响成为关注中心.     

从《晏子春秋》看晏婴的哲学思想

晏婴作为一个深受太史公司马迁赞誉的先秦齐国贤相,其事迹大多记载在《晏子春秋》之中。本文以《晏子春秋》为基本依据,以《左传》记载为印证,就晏婴的哲学思想进行了探讨,认为晏婴的哲学思想突出表现在其倡导并实践的对事物的朴素辩证思维以及轻鬼神重人事的无神观上。同时,本文还对晏婴哲学思想的时代局限性和对中国现当代的影响进行了初步探析。

ω-phase formation in a rapidly solidified Cr-40 at.% Al alloy

The diffuse ω structure has been identified by electron diffraction for the first time in a C11_b matrix of the melt-spun Cr-40 at.% Al alloy ribbon. The C11_b matrix consists of nanometre-scale ordered domains produced by a long-period chemical ordering in the precursor A2-B2 structure. Each C11 _b unit cell in the Cr-40 at.% Al alloy is based on three cubic B2 cells along the c axis and contains two antiphase boundaries. The structure of the diffuse ω is consistent with that observed by De Fontaine. The relative stability of the crystalline ω structure has been predicted with respect to bcc-type precursor phases as a function of the displacement parameter z from calculation of the cohesive energy of the ω phase using the full-potential linear muffin-tin orbital method. The results show that the three-dimensional crystalline ω structure is stable with respect to bcc-type precursor phases in the Cr-Al system and reveals the physical background as to why the ω structure in Cr-40 at% Al is diffuse in nature.     

EMA-一种生态主义取向的研究模式

生态瞬时评估（EMA）不是一个单一的研究方法,而是一种研究模式,它强调现实世界中实时数据的采集和反复的评估,并能阐释变量间自然存在和变化的相互关系,具有很高的生态学效度。EMA的使用会加强我们对个体与环境之间的动态交互作用的理解。EMA的基本设计思路包括基于事件的设计、基于时间的设计和联合设计。在EMA 的使用中还有一些问题如软硬件的发展、伦理、数据等问题等需要研究者注意。目前EMA应用最广泛的领域是临床心理学和行为研究方面。     

Sources of individual differences in the speed of naming objects and actions: The contribution of executive control

We examined the contribution of executive control to individual differences in response time (RT) for naming objects and actions. Following Miyake et al., executive control was assumed to include updating, shifting, and inhibiting abilities, which were assessed using operation span, task-switching, and stop-signal tasks, respectively. Experiment 1 showed that updating ability was significantly correlated with the mean RT of action naming, but not of object naming. This finding was replicated in Experiment 2 using a larger stimulus set. Inhibiting ability was significantly correlated with the mean RT of both action and object naming, whereas shifting ability was not correlated with the mean naming RTs. Ex-Gaussian analyses of the RT distributions revealed that updating ability was correlated with the distribution tail of both action and object naming, whereas inhibiting ability was correlated with the leading edge of the distribution for action naming and the tail for object naming. Shifting ability provided no independent contribution. These results indicate that the executive control abilities of updating and inhibiting contribute to the speed of naming objects and actions, although there are differences in the way and extent these abilities are involved.
