This study investigated the status quo of article retractions by Chinese researchers. The bibliometric information of 834 retractions from the Web of Science SCI-expanded database were downloaded and analysed. The results showed that the number of retractions increased in the past two decades, and misconduct such as plagiarism, fraud, and faked peer review explained approximately three quarters of the retractions. Meanwhile, a large proportion of the retractions seemed typical of deliberate fraud, which might be evidenced by retractions authored by repeat offenders of data fraud and those due to faked peer review. In addition, a majority of Chinese fraudulent authors seemed to aim their articles which contained a possible misconduct at low-impact journals, regardless of the types of misconduct. The system of scientific evaluation, the “publish or perish” pressure Chinese researchers are facing, and the relatively low costs of scientific integrity may be responsible for the scientific integrity. We suggested more integrity education and severe sanctions for the policy-makers, as well as change in the peer review system and transparent retraction notices for journal administrators.  相似文献

人格与智力:一种交互作用的模型   总被引:2,自引:1,他引:2  
该文在考察人格与智力的概念本质及其相互关系的基础上,指出了人格与智力之间可能包含的四层关系,Chamorro和Furnham(2004)提出的人格—智力关系的交互作用模型正是通过详细分析这些关系构建起来的理论模型。该模型以人格特质为中心,将主观评估智力(SAI)作为人格与IQ测试成绩之间的中介变量,深入阐述了大五人格特质与流体智力、晶体智力、主观评估智力、IQ测试成绩及其与认知操作之间的交互作用,为理解人格与智力的关系提供了一种新思路  相似文献

英语单词记忆过程中策略的选用和评价的研究   总被引:2,自引:0,他引:2  
问卷结果表明 :普通大学生和 GRE考生在有关记忆过程的知识方面没有差异 ;绝大多数 GRE考生有选用“较多的”策略趋势 ,且在规定单词记忆量和精细加工策略方面差异显著 ;两类被试在对策略的评价的总体上具有一致性 ,但两类被试在选择比较有效和值得推荐的策略时 ,在一些自我监控策略上的选取比率表现出差异 ,在选择效果不佳和基本无效策略时 ,在某些一般记忆加工策略上选取比率也存在差异 ;绝大多数被试推荐策略是基于经验 ,判定策略无效是源于直觉判断。本文结合前人的研究成果 ,探讨了知识、情景因素与策略的选择和运用的关系 ;提出了实际学习情景下策略有效性意识形成的两个因素及可能途径。  相似文献

采用学习迁移任务范式,使用基于单一特征的类别判断技术,比较了三水平特征的家族性似性类别结构下,分类学习和推理学习的学习效率、学习过程与策略和学习结果.结果表明:在学习效率上,分类学习在达标率上优于推理学习,而在速度上,两者差异不显著.在学习的过程与策略上 ,推理学习相对较快地从单维度策略转向使用规则加例外策略,而分类学习表现出一定程度的潜伏学习, 并在高水平的信息整合策略使用上,赶上了推理学习.在学习的结果上,分类学习比推理学习更好掌握了类别的原型.  相似文献

This study investigated 5‐ to 13‐year‐old children's performance in solving horizontal projectile motion problems, in which they predicted the trajectory of a carried object released from a carrier in three different contexts. The results revealed that 5‐ and 8‐year‐olds' trajectory predictions were easily distracted by salient contextual features (e.g. the relative spatial locations between objects), whereas a proportion of 11‐ and 13‐year‐olds' performance suggested the engagement of the impetus concept in trajectory prediction. The impetus concept is a typical misconception of inertial motion that assumes that motion is caused by force. Children's performance across ages suggested that their naïve knowledge of projectile motion was neither well‐developed and coherent nor completely fragmented. Instead, this study presented the dynamic process in which children with age gradually overcame the influences of contextual features and consistently used the impetus concept across motion problems.  相似文献

We investigate the location patterns of organizations that embody key religious‐spiritual traditions and that have grown to prominence in the latter 20th and early 21st centuries: evangelical churches, yoga, and martial arts. The distribution of key cultural organizations depends on the degree to which they are able to frame themselves in relation to one another and to core American traditions. Organizations associated with the American religious divide are more polarized in their social appeal and spatial distributions, and those framed as broadly neutral elements of popular culture are more widely distributed. Using a national database of local amenities, we find that theologically conservative churches are popular in many neighborhoods but concentrated in less‐educated and nonwhite areas. Yoga studios are less geographically dispersed and more spatially concentrated in college‐educated and white areas. Compared to these, martial arts schools, sports clubs, and other pop‐culture amenities are more widely distributed across different types of areas.  相似文献

While some studies suggest cultural differences in visual processing, others do not, possibly because the complexity of their tasks draws upon high‐level factors that could obscure such effects. To control for this, we examined cultural differences in visual search for geometric figures, a relatively simple task for which the underlying mechanisms are reasonably well known. We replicated earlier results showing that North Americans had a reliable search asymmetry for line length: Search for long among short lines was faster than vice versa. In contrast, Japanese participants showed no asymmetry. This difference did not appear to be affected by stimulus density. Other kinds of stimuli resulted in other patterns of asymmetry differences, suggesting that these are not due to factors such as analytic/holistic processing but are based instead on the target‐detection process. In particular, our results indicate that at least some cultural differences reflect different ways of processing early‐level features, possibly in response to environmental factors.  相似文献

研究旨在考察汉语学龄前儿童正字法意识的发展情况。在某中等城市一所幼儿园随机选择4岁、5岁、6岁三个年龄段的儿童各31、37、34名。实验一使用汉字、韩文和日文(平假名)作为实验材料探查学龄前儿童的汉字特异性意识;实验二使用上下结构、左右结构的真字、假字和非字考察学龄前儿童的部件位置意识。实验结果显示:(1)三组儿童都能区分日文和汉字,5岁左右儿童这种能力达到成熟。4岁儿童不能区分汉字和韩文,直到6岁,辨别汉字和韩文的能力也没有发展成熟。(2)三组儿童都能意识到假字符合正字法规则,但拒绝非字的能力在学前期尚未发展成熟,儿童在学前期不具备部件位置意识;6岁儿童更容易拒绝上下部件位置颠倒的非字。  相似文献

亲社会行为是指有利于他人和社会的行为,包括合作、分享、助人、安慰等。亲社会行为产生主要涉及几种认知过程:对他人行为和情绪的注意、社会信息加工、对结果的奖赏预期、社会规范表征、自我控制、以及社会信息整合与价值计算等。基于这些认知过程,研究发现,亲社会行为主要与前脑岛和前扣带回、默认网络背内侧子系统、奖赏系统以及前额叶皮层等神经区域有关,因此提出亲社会行为共同的认知-脑神经回路。未来可以对亲社会行为脑神经基础的共性、功能连接以及跨文化研究等方面做进一步探讨。  相似文献
