从词汇的角度看《撰集百缘经》的译者及成书年代

目前学术界对《撰集百缘经》的作者与成书年代看法不一,本文主要从文献与词汇的角度对《撰集百缘经》作一番考定。     

自主创新的心理发生机制研究

自主创新是社会、自然和人类自身的发展变化,与一个国家或企业原有发展水平之间的矛盾所产生的创新需要向个体身上转化,与个体自我实现的需要相互作用而产生的。一般经过创新需要的形成、转化、现实化,再由创新需要转化为创新动机而引发。可分为有意自主创新和无意自主创新两种类型。     

中小学生惯用语理解发展的研究

对惯用语理解的发展 ,是儿童语言发展的重要方面。本研究结果表明 ,在无语境条件下 ,中小学生对惯用语的理解年级差异显著 ,小学生和中学生差异较大 ,而小学和中学各年级内部差异不显著。学生对惯用语是先理解字面意义 ,再理解比喻意义。在有语境条件下 ,不同年级学生对惯用语的理解差异显著 ,惯用语语义倾向性的影响不显著 ,但语境对学生惯用语理解有重要影响 ,高年级学生能更好地利用语境。     

Is recognition accuracy really impaired when the target is repeated in the display?

Bjork and Murray (1977) have presented a feature-specific interactive channels model that predicts perceptual interference between letters presented simultaneously in visual displays. Maximum interference is predicted when a target letter is presented with an identical letter. In their experiment, Bjork and Murray found support for their model, but their results could have occurred artifactually from response biases of their subjects. Santee and Egeth (1980) used a different paradigm that eliminated the possibility of this particular response bias and reported that their data supported the feature-specific model. However, the present paper shows that analysis of their data by Santee and Egeth was incomplete and the comparisons inappropriate. In two experiments that used the Santee and Egeth paradigm, we failed to find support for the feature-specific model when more detailed analyses of the data were undertaken. In a third experiment, one that used the Bjork and Murray paradigm, but with control of response bias, no significant or suggestive evidence was found that feature similarity between noise and target letters affected recognition of the latter.     

Optimism across cultures: In response to the severe acute respiratory syndrome outbreak

Based on our early research, we predicted that the Chinese may be more optimistic and less pessimistic than North Americans in response to negative life events. A survey was conducted to investigate optimism cross culturally in the context of the severe acute respiratory syndrome (SARS) outbreaks in Canada and China. Chinese students in Beijing and European Canadians in Toronto answered questions about their perceptions of SARS. No significant cultural difference was found on dispositional optimism, as measured by the Revised Life Orientation Test (LOT-R). Unrealistic optimism was measured in the context of SARS. Both groups demonstrated unrealistic optimism (i.e. reporting that the self was less likely than an average person to get infected with SARS). Such optimistic bias was stronger among Chinese than among Canadians. Compared to the actual infection rates in Beijing and Toronto, both Chinese and Canadian participants overestimated their own chances of getting infected, indicating that they were being pessimistic. Indeed, Chinese were less pessimistic than Canadians. In addition, even though the Chinese reported more inconvenience brought by SARS than did Canadians, they also reported more positive changes brought by SARS, reflecting the Chinese dialectical views of events. Implications for research on optimism in context are discussed.     

Independence between implicit and explicit processing as revealed by the Simon effect

Studies showing human behavior influenced by subliminal stimuli mainly focus on implicit processing per se, and little is known about its interaction with explicit processing. We examined this by using the Simon effect, wherein a task-irrelevant spatial distracter interferes with lateralized response. Lo and Yeh (2008) found that the visual Simon effect, although it occurred when participants were aware of the visual distracters, did not occur with subliminal visual distracters. We used the same paradigm and examined whether subliminal and supra-threshold stimuli are processed independently by adding a supra-threshold auditory distracter to ascertain whether it would interact with the subliminal visual distracter. Results showed auditory Simon effect, but there was still no visual Simon effect, indicating that supra-threshold and subliminal stimuli are processed separately in independent streams. In contrast to the traditional view that implicit processing precedes explicit processing, our results suggest that they operate independently in a parallel fashion.     

小学儿童的尊重观念及其发展

以开放式尊重观念问卷对小学三到六年级儿童进行集体施测研究儿童的尊重观念,结果发现：(1)小学儿童认为尊重就是有礼貌,尊重对象的特征和尊重原因都是要求对方品质好或学习好。尊重的对象既有长辈又有同辈,提到尊重同辈的显著多于只尊重长辈的。不同的人际背景下,儿童的尊重观念不一致。(2)小学儿童的尊重观念具有显著的发展特征,表现出从单向尊重到双向尊重的发展趋势。不同人际关系下的尊重观念的发展特征不同,对父母和老师的尊重主要为单向尊重,对朋友的尊重主要为双向尊重。(3)小学儿童的尊重观念具有显著的性别差异。     

Shear vibration of a crystal plate carrying an array of microbeams

We study shear vibration of a rotated Y-cut quartz crystal plate carrying an array of microbeams with their bottoms fixed to the top surface of the plate. The beams undergo flexural vibrations when the plate is in shear motion. The plate is modeled by the theory of anisotropic elasticity. The beams are modeled by the Euler–Bernoulli theory for beam bending. A frequency equation that determines the resonant frequencies of the structure is derived. An analytical solution on beam-induced frequency shift is obtained using a perturbation procedure. It is shown that the frequency shift may be used to measure geometric/physical properties of the beam array. A vibrating crystal plate carrying a beam array may also be considered for application as an ultrasonic brush.

<正>向思维是常规的思维方法,大多数问题可通过正向思维解决,但一些问题正向思维无法解决,而负向思维是有效的,可成为正向思维的替补。本文研究了负向思维解决问题的原理和方法,提出了问题的负向作用加返向作用的负向思维解决法,为运用负向思维解决问题提供了理论依据和方法。     

中国临床遗传学检测的伦理问题

遗传伦理问题是生命科学领域最具争议的问题之一.针对基因诊断的"知情权"、"优劣"胎儿的选择、基于人群的基因筛查、发病前及患病风险的基因检查、全基因组筛查以及植入前遗传诊断中所涉及的伦理前沿问题进行讨论.提出基因检测是否应该重申把伦理考虑放在第一位.
