Moganopterus zhuiana L?et al. 2012 was erected as a member of the Boreopteridae, which was questioned by different researchers shortly after the publication. Although the new assignment to the Ctenochasmatidae is widely accepted by pterosaur researchers, some characteristics still require a detailed description. Here, the holotype of this taxon is restudied, and some ambiguous characteristics are re-identified. The diagnosis of this taxon has been revised as the following: a large ctenochasmatid pterosaur, which can be distinguished from other members of this clade by a single autapomorphy: an elongated rod-like parietal crest that extends posterodorsally, forming an angle of about 15?with the ventral margin of the skull. This taxon can be further distinguished from other ctenochasmatids on the basis of the following combination of characteristics: straight occlusal surfaces of the upper and low jaws; presence of a low premaxillary crest confined anterior to the nasoantorbital fenestra; rostrum about two thirds of the skull length; nasoantorbital fenestra occupying slightly more than 20% of the skull length; about 100 slender teeth; and a mid-cervical length/width ratio of about 7. The wingspan of M. zhuiana has been re-estimated according to a simple regression equation for wingspan versus skull length in ctenochasmatids. It confirms that M. zhuiana, although smaller than previous thought, is still the largest known ctenochasmatid. When comparing the sizes of ctenochasmatids in the Jurassic and Cretaceous, ctenochasmatids showed a rough tendency to increase their sizes.

Ladderpath theory: A new look at complexity and information

Liu, Yu; Di, Zengru; Gerlee, Philip
Subjects: Information Science and Systems Science >> Basic Disciplines of Information Science and Systems Science

The notion of information and complexity are important concepts in many scientific fields such as molecular biology, evolutionary theory and exobiology. Most measures of these quantities, such as Shannon entropy and related complexity measures, are only defined for objects drawn from a statistical ensemble and cannot be computed for single objects. We attempt to fill this gap by introducing the notion of a ladderpath which describes how an object can be decomposed into an hierarchical structure using repetitive elements. From the ladderpath two measures naturally emerge: the ladderpath-index and the order-index, which represent two axes of complexity. We show how the ladderpath theory can be applied to both strings and spatial patterns and argue that all systems that undergo evolution can be described as ladderpaths. Further, we discuss possible applications to human language and origins of life. The ladderpath theory provides a novel characterization of the information that is contained in a single object (or a system) and could aid in our understanding of evolving systems and the origin of life in particular.

团队行动中反思与团队创新关系研究的动态视角 ——认知与情绪的双元路径

刘薇; 沈晓玲
Subjects: Management Science >> Development and Management of Human Resources

在复杂变化的市场环境中,在我国实施创新驱动战略的背景下,企业的长远发展需要依赖于团队创新以建立独特竞争优势。通过对已有团队反思与创新关系研究的梳理,发现了二者间关系的黑箱,理论认为回顾过去能够带来新思想和新变化,然而针对其如何实现的过程机制的实证研究却十分匮乏。基于此,在传统的行动后反思的思想基础上,本研究提出团队行动中反思在概念内涵和实证测量上的区别,检验行动中反思和行动后反思在不同创新阶段的差异性作用,动态性分析创意形成和创意实施的行为结果,通过整合动机性信息加工理论和情绪的社会功能视角,提出认知层面的信息处理和情感层面的团队情绪这两种机制的耦合方式,构建团队反思影响创新的整体模型,并深入探讨影响作用的过程机制和边界条件,以及对各阶段关系上情境因素的调节作用进行全面的分析,为反思与创新理论和实践做出贡献。

智慧时代的螺丝钉:机器人凸显对职场物化的影响

Subjects: Psychology >> Management Psychology

在“工具人”、“打工人”、“社畜”等流行语风靡职场的当下,职场物化已然成为了一个亟需探讨的话题。而随着人工智能尤其是机器人在职场中的使用日益增多,机器人产生的职场效应也值得关注。因此,本项目旨在探讨在人工智能飞速发展的当今社会,机器人渗入职场是否会产生或加重职场物化现象。基于群际威胁理论和补偿控制理论,我们假设职场中的机器人员工凸显会增加职场物化。项目采用实验、大数据与问卷调查相结合的方式,首先考察机器人员工的凸显是否会增加职场物化,初步验证影响效应;然后探讨机器人影响职场物化的中介机制,试图发现感知威胁和控制补偿的链式中介效应;最后从个人、机器人和环境三方面分别考察其对机器人影响职场物化的调节作用,并从组织文化的角度探讨对职场物化的干预策略。对本项目的探索有助于结合人工智能尤其是机器人发展背景,前瞻性地了解人工智能在职场中可能的负面影响,并提出有效的解决方案。

心理治疗中隐喻的使用、疗效检验及作用机制

于冠琳; 刘瑞璇; 张文彩
Subjects: Psychology >> Clinical and Counseling Psychology

隐喻在心理治疗中的应用非常普遍,语言学和心理学中的基本隐喻理论强调隐喻具有高创造性、记忆保持和增强卷入等认知加工优势,几种心理治疗理论也认为治疗性隐喻的无意识意义交换、图式重构、直觉经验等加工特征可能在治疗信息传递上具有独特的增强作用。在此基础上,现有的实证研究证据大多支持治疗性隐喻的心理干预效果优于非隐喻干预,其治疗优势的心理神经机制主要来源于隐喻诱发的创造性顿悟、更佳的长时记忆和更强的认知卷入。未来研究需从对照组设置、效果指标、机制探索方面来进一步观察在治疗性隐喻的独特优势,并为研发嵌入隐喻的低成本高效益的社会心理健康服务方案提供了建议。

Subjects: Psychology >> Cognitive Psychology

通过两个实验探讨认知负荷对不同学业成就小学生前瞻记忆及其成分的影响,以及是否可以通过执行意向编码提高学业不良小学生前瞻记忆及其成分的成绩。实验一结果显示学业不良生前瞻记忆、前瞻成分及回溯成分正确率显著低于学优生,高认知负荷条件前瞻记忆、前瞻成分及回溯成分的正确率显著低于低认知负荷条件;实验二结果显示执行意向编码条件下,学业不良生前瞻记忆成绩显著好于标准编码条件,前瞻成分和回溯成分的正确率高于标准编码条件。结果表明学业不良生前瞻记忆及其成分表现差于学优生;无论认知负荷高低,执行意向编码均可通过提升前瞻成分和回溯成分改善学业不良生前瞻记忆表现。
