听觉通道下负数的低水平加工引起注意的SNARC效应

采用刺激探测任务,探讨了听觉通道下负数的低水平加工能否引起注意的SNARC效应。结果表明:(1)负数的低水平加工能够产生注意的SNARC效应,即线索为绝对值小的负数时,被试对左耳目标反应更快;线索为绝对值大的负数时,被试对右耳目标反应更快。(2)负数的加工所引起听觉空间注意的转移并不依赖于负数所在的情境,而仅通过其绝对值大小与空间表征发生关联。这一结论与视觉条件下所得到的结论不一致,并支持了系统发生论假说。     

Revealing texture architecture in a surface gradient nanostructured Al-Cu-Mg alloy

ABSTRACT

A multiscale crystallographic texture architecture in a surface gradient nanostructured Al-Cu-Mg alloy after surface sliding friction treatment (SSFT) has been revealed by a combination of electron backscatter diffraction and precession electron diffraction (PED)-assisted transmission electron microscopy (TEM) orientation mapping. Accompanying a grain structure variation from lamellar coarse grains to equiaxed nanograins, the major texture components evolve from brass {110}<112> in the coarse-grain matrix, Goss {110}<001> at a depth of ～80?μm, E {111}<011> and F {111}<112> at a depth of ～20?μm, to a mixture of rotated cube {001}<110>, E and F in the topmost surface layer. The through-thickness textural development and evolution are attributed to the cyclic loading of concurrent shear and compression during the SSFT processing. The PED-assisted orientation mapping shows good capability in mapping severe plastic-deformation-induced nanostructures with large residual strains and high defect density.     

Computer-aided analysis of grain-boundary connectivity of B10 copper-nickel alloys

A numerical calculation method based on the angle in a triple junction composed of a random grain boundary is proposed to predict the connectivity and stability of a grain boundary in a B10 copper-nickel alloy. The grain-boundary connectivity and its effect on corrosion resistance are studied combining computer-aided analysis with electrochemical impedance testing. The results show that the prediction of corrosion resistance using a grain-boundary connectivity numerical method is consistent with immersion experimental results. The B10 alloy exhibited the best corrosion resistance after cold rolling with a 9% reduction rate. The relationship between the grain-boundary characteristics and corrosion resistance is well established using the numerical method to quantify the grain-boundary connectivity. A higher connective frequency and a low proportion of grain-boundary angles between 60° and 180° in the triple junction is detrimental to corrosion resistance of the B10 alloy.     

On the automaticity of contingent capture: disruption caused by the attentional blink

Converging evidence has shown that onset capture can be completely eliminated by the demands of a concurrent task and during the attentional blink. In the present study, we investigated contingent capture during the attentional blink. We found that contingent capture was attenuated, or even completely eliminated, during the “blink” time of the attentional blink. These results indicate that contingent capture requires limited attentional resources.     

转化医学应用现状及其困境分析

转化医学的理念已经蓬勃发展起来,但对大多数处于临床一线的医生而言,却产生了较多困惑:基础医学与临床医学之间仍相互脱节,许多先进的基础医学研究难以为临床实践所用,基础医学的先进成果向临床的转化难以实现.因此,对于转化医学理念的提出,应有所反思,使转化医学的价值得以充分地发挥.     

跨文化护理理论在当代护理教育中的应用

当代护理教育面临教育对象及护理对象文化背景多元化特征.教学中,应根据教学及护理对象的文化差异,以跨文化护理理论为指导,对护理教育的课程设置、教学方法和考核方式进行改革,以灌输学生跨文化护理理念,培养具有跨文化护理意识,适应社会需求的复合型护理人才.     

关于马基雅维利主义的道德心理研究

上世纪60～70年代,Christie创造了马基雅维利主义的心理学构念,而Exline,Geis和Bogart开创了关于马基雅维利主义的道德心理研究,后继研究者继承并不断完善他们的实验方法,探讨了马基雅维利主义与不道德行为(尤其是欺骗和逢迎)、道德判断(包括道德观和道德推理)、道德教育的关系。研究结果发现,尽管有证据证明马基雅维利主义与不道德行为存在密切关系,但两者是否是直接的因果关系仍存争议,不过多数学者一致认为马基雅维利主义者的不道德行为缘于其道德判断和道德教育,他们决策时将传统道德标准排除在决策标准体系之外,因此描述他们道德判断应采用"非道德"而不是"不道德"。     

母亲元情绪理念与儿童情绪调节能力发展的关系：母亲情绪调节的中介作用

以540名小学一、三、五年级儿童的母亲为对象,采用回归分析和路径分析技术,考察了母亲元情绪理念及其情绪调节对儿童情绪调节能力发展的预测作用及其机制。结果表明：（1）母亲情绪教导和情绪紊乱理念对儿童情绪稳定性的发展具有直接预测作用,且以其高冲动性为中介对儿童情绪稳定性的发展具有间接预测作用;（2）母亲情绪教导理念对儿童情绪调节性的发展具有直接预测作用,且以其情绪调节策略缺乏为中介对儿童情绪调节性的发展具有间接预测作用。因此,母亲情绪教导理念有助于其不良情绪的控制和更加灵活多样的情绪调节策略,而对自身不良情绪的有效控制和更灵活的情绪应对策略,将有助于促进其孩子情绪调节能力的发展。     

A Study on School Leaders' Ethical Orientations in Taiwan

The purpose of this study is to explore the ethical orientations of Taiwan's school leaders by means of a questionnaire survey of 573 school leaders. A multidimensional ethical framework, including utilitarianism, justice, care, critique, and virtue, was used. The results demonstrate that the most frequent ethical orientation of Taiwan's school leaders is justice. Second, the ethical orientation of Taiwan's school leaders is influenced by Confucian ethics to some degree, especially in terms of virtue ethics. However, the ethical orientation of school leaders significantly varies depending on gender, age, position, years of teaching experience, and educational administration ethics training.     

Inside the leader relationship: constructive controversy for team effectiveness in China

Research is needed to understand the dynamics by which high‐quality leader relationships have their productive effects on followers. This study proposes that these leader relationships do not simply induce compliance but encourage employees and managers to discuss their diverse views open‐mindedly and constructively. Team leaders indicated leader–member relationship with employees who rated their constructive controversy and their team's effectiveness and feelings of respect, support, and reduced stress. Structural equation analysis suggested that leader–member relationship affects employee team productivity and emotions through constructive controversy. The study's findings and previous research were interpreted as suggesting that high‐quality leader relationships coupled with constructive controversy provide a foundation for effective team leadership in China.
