Effect of Mg content on Portevin–Le Chatelier band strain in Al–Mg sheet alloys

Experimental measurements of stress drops and band strains in type-B Portevin–Le Chatelier (PLC) bands were carried out for 5xxx series Al–Mg sheets with Mg content between 1.8 and 4.5?wt%. While the stress drops increase with global strain, the band strain values in all the samples follow a common linear relationship with global strain. The results indicate that the type-B PLC band strain is independent of solute content at given strain rate.     

从整合医学视角看心血管学科未来发展

心血管疾病已经成为威胁国人健康的首位疾病.现代医学的发展使药物、介入和外科手术成为治疗心血管疾病的三大基石,但专科的进一步细化也带来相当多的弊端.因此,需要以患者为核心,摒弃学科的分野,将各种医学知识和防治手段有机融合,构建一个新的整合医学体系去培养年轻医师,切实控制心血管疾病.     

动物和人类的利他本性:共情的进化

共情指个体感知或想象其他个体的情感,并部分体验到其他个体感受的心理过程.利他指以增加其他个体的福利为最终目标的动机.共情起源于动物的亲代养育行为,其神经基础来源于古老的情感系统.共情从动物低水平的情绪感染逐渐进化到同情关注以及观点采择共情.另外,共情具有良好的环境适应性.未来可以进一步研究动物与人类的共情和利他行为的异同,加大研究动物的高级共情能力和利他行为以及深入研究共情受社会因素的调节机制.     

工作不安全感、创造力自我效能对员工创造力的影响

采用问卷调查法, 以286对上级-下属配对数据为样本, 探讨了工作不安全感、创造力自我效能对员工创造力的影响及其内在作用机制。结果表明, 工作不安全感对员工创造力有倒U形的影响, 中等工作不安全感水平下员工的创造力最高; 创造力自我效能对员工创造力有显著的积极影响; 工作不安全感与创造力自我效能的交互效应显著, 创造力自我效能越高, 工作不安全感对员工创造力的影响越小; 工作不安全感、创造力自我效能及其交互效应通过内在动机的完全中介效应影响员工创造力。     

不同视觉区域OUP效应的眼动研究

摘 要 采用眼动方法,通过两个实验考察了不同视觉区域的OUP效应。结果显示：（1）当刺激材料分别平行呈现于左侧视觉区域和右侧视觉区域时,在右侧视觉区域产生了OUP效应,而在左侧视觉区域没有OUP效应,我们假设是由于左侧视觉区域首字母距离中央凹的不利位置影响了OUP效应的产生。（2）当垂直方向呈现刺激时,在两侧视觉区域均产生了明显的OUP效应,表明首字母距离中央凹处于有利位置时不会影响OUP效应的产生。实验结果支持了大脑左半球和右半球在词汇识别时的策略为系列加工,对左半球平行加工右半球系列加工的结论提出了质疑。     

心理健康素质测评系统·中国成年人人际健康素质量表的编制

在文献分析和专家评定的基础之上,构建了人际健康素质的基本结构,并编制了初始的中国成年人人际健康素质问卷。然后通过项目区分度分析和验证性因素分析对初始问卷进行了修订,最终形成了包括合群性、亲仁性、利他性、共情性和友善性5个维度的正式量表。结果表明,人际健康素质量表具有较高的内部一致性信度、重测信度和分半信度以及较好的内容效度、结构效度、校标关联效度和会聚效度。结论：人际健康素质量表具有较好的心理测量学特征,可以作为中国成年人人际健康素质的心理测量工具。

商业银行员工满意度研究

商业银行的经营目标是利润,服务是实现利润的行为过程,服务的宗旨是满足优质客户的合理需要、培育客户忠诚。客户忠诚度取决于客户的满意度,客户满意度取决于客户的感知价值。员工作为服务的载体,其服务质量决定了客户的感知价值,而服务质量决定于员工的满意度和忠诚度。     

Is Mozi a utilitarian philosopher?

In this essay I argue that Mozi’s philosophy is anything but utilitarianism by way of analysing four ethical theories. Utilitarianism is an ethics in which the moral subject is an atomic individual human being, and its concern is how to fulfill the interests of the individual self and the social majority. Confucian ethics is centered on the notion of the family and its basic question is that of priority in the relationship between the small self and the enlarged or collective self. Opposite to these two moral theories is Mozi’s ethics: The interests that Mozi is primarily concerned with are not the interests of my individual self or my collective self, but the interests of the other. The fulfillment of the material needs of the other is my moral obligation. The arguments are centered on the three basic concepts, “the I,” “the we,” and “the other.” The significance of Mozi’s thought in modern or postmodern context lies in its striking resemblance to the philosophy of a contemporary western philosopher, Levinas. In both Mozi and Levinas, there is a suspension of utilitarianism. __________ Translated from Zhongguo Zhexue Shi 中国哲学史 (History of Chinese Philosophy), 2005 (1)     

To and from philosophy — Discussions with Gödel and Wittgenstein

I propose to sketch my views on several aspects of the philosophy of mathematics that I take to be especially relevant to philosophy as a whole. The relevance of my discussion would, I think, become more evident, if the reader keeps in mind the function of (the philosophy of) mathematics in philosophy in providing us with more transparent aspects of general issues. I shall consider: (1) three familiar examples; (2) logic and our conceptual frame; (3) communal agreement and objective certainty; (4) the transcommunal universality of mathematics; (5) the big jump to the potential infinite; (6) the reconciliation of local creation with the hypothesis of discovery; (7) Platonism as realism plus conceptualism; (8) foundational studies and mathematical practice; and (9) the decomposition of philosophical disagreements. The views of Gödel and Wittgenstein are emphasized in order to add specificity to the discussions.
