The crystal polarity of wurtzite zinc oxide nanorods grown hydrothermally parallel to the c?=?[0001] direction has been determined by convergent-beam electron diffraction using a defocused probe. The method enables a simple comparison of the diffracted intensities in ±0002 reflections across side-on nanorods, demonstrating growth in this case is in the c?=?[0001] direction. The method is shown to be viable for nanorods down to about 11?nm in diameter. 相似文献

Previous studies using Western samples have found that introducing uncertainty to an intertemporal choice decreases the degree of discounting future rewards. The authors of this article examined the effect of risk on intertemporal choice using Chinese participants and found that respondents preferred the smaller but sooner (SS) outcome to the larger but later (LL) one in the presence of risk, which indicates that risk increases rather than decreases the degree of discounting future rewards. Thus, variations in response patterns between different cultural groups suggest that culture may play an important role in intertemporal choice and researchers should delve into this topic from an emic rather than an etic perspective. 相似文献

This paper demonstrates the effects of different priming conditions on the endowment effect with respect to seller and buyer roles for individuals with different loci of control. Individuals with an external locus of control process information less rationally, and they are more susceptible to external influences. In addition, the literature reports that when individuals are making a purchasing decision, they tend to perceive the value of the product as being higher because of its utility aspect because decision makers search for reasons and arguments to justify their choices (Shafir 1993; Tversky & Griffin, 1991). Therefore, this study investigates the effects of different priming conditions (utilitarian priming vs. hedonic priming) on the endowment effect according to each type of locus of control (internal vs. external). The results showed that the endowment effect was larger when externals were exposed to utilitarian priming as opposed to hedonic priming. Finally, the implications of these findings and suggestions for future research are discussed. 相似文献

The quantifier dou (roughly corresponding to English ‘all’) in Mandarin Chinese has been the topic of much discussion in the theoretical literature.
This study investigated children’s knowledge of this quantifier using a new methodological technique, which we dubbed the
Question-Statement Task. Three questions were addressed: (i) whether young Mandarin-speaking children know that dou is a universal quantifier that quantifies over the elements to its left, (ii) whether they know that dou is an adverb of quantification (Q-adverb) which can (unselectively) bind any variable in its domain, and (iii) whether they
know that dou can quantify over wh-words. The main finding was that, by age four, Mandarin-speaking children have the relevant knowledge. The results reflect
the early availability of adult-like linguistic knowledge of dou-quantification. 相似文献

Effective literacy education in deaf students calls for psycholinguistic research revealing the cognitive and neural mechanisms underlying their written language processing. When learning a written language, deaf students are often instructed to sign out printed text. The present fMRI study was intended to reveal the neural substrates associated with word signing by comparing it with picture signing. Native deaf signers were asked to overtly sign in Chinese Sign Language (CSL) common objects indicated with written words or presented as pictures. Except in left inferior frontal gyrus and inferior parietal lobule where word signing elicited greater activation than picture signing, the two tasks engaged a highly overlapping set of brain regions previously implicated in sign production. The results suggest that word signing in the deaf signers relies on meaning activation from printed visual forms, followed by similar production processes from meaning to signs as in picture signing. The present study also documents the basic brain activation pattern for sign production in CSL and supports the notion of a universal core neural network for sign production across different sign languages. 相似文献

新近出现的绩效结构理论认为员工绩效包括角色内行为、组织公民行为和工作越轨行为三种类型。然而在后两种行为的关系上,当前研究者还未达成一致意见。文章综合采用三种方式证实了组织公民行为和工作越轨行为是两种完全不同的行为类型,而不是一种行为的两种性质不同的表现,从而为三维绩效模型的合理性提供了间接支持。在此基础上,研究还证实了工作越轨行为中两种成分(组织越轨和人际越轨)的不同。文章最后对研究结果进行了讨论,并指出了未来研究方向。 相似文献
