QZNs: Quantum Z-numbers

Deng, Jixiang; Deng, Yong
Subjects: Computer Science >> Integration Theory of Computer Science

Because of the efficiency of modeling fuzziness and vagueness, Z-number plays an important role in real practice. However, Z-numbers, defined in the real number field, lack the ability to process the quantum information in quantum environment. It is reasonable to generalize Z-number into its quantum counterpart. In this paper, we propose quantum Z-numbers (QZNs), which are the quantum generalization of Z-numbers. In addition, seven basic quantum fuzzy operations of QZNs and their corresponding quantum circuits are presented and illustrated by numerical examples. Moreover, based on QZNs, a novel quantum multi-attributes decision making (MADM) algorithm is proposed and applied in medical diagnosis. The results show that, with the help of quantum computation, the proposed algorithm can make diagnoses correctly and efficiently.

随着行业竞争压力的加剧,工作狂领导在职场中愈发普遍。然而对于工作狂领导在组织中的有效性,无论是在实践界还是在学术界都尚存争议。鉴于此,本研究基于社会信息加工理论,分析工作狂领导对团队绩效的双刃剑作用机制。通过对某物业管理服务公司进行多时点、多来源的问卷调查,研究结果表明:一方面,工作狂领导会提升团队工作卷入,促进团队绩效;另一方面,工作狂领导也会引发团队消极情绪,损害团队绩效表现;团队工作重要性能有效缓解工作狂领导对团队绩效的消极作用,同时促进其积极作用。以上研究发现有助于辨证理解工作狂领导有效性,为组织培育管理**提供有益借鉴。

重复性急性应激对攻击行为的影响及调控机制

关于急性应激对攻击行为的影响,现有研究多集中于单次急性应激情境下。然而,相比单次急性应激,对重复暴露于同一应激源的研究更能反映人们在现实生活中经历的应激事件。与单次应激不同,重复性急性应激与应激适应有关,能够节省资源,具有很强的进化和适应意义,但目前关于重复性急性应激对攻击行为的影响却知之甚少。鉴于此,研究运用事件电位相关技术、鼻喷催产素和催产素受体基因型分析方法,探讨重复性急性应激对攻击行为的影响及内部机制,并进一步探讨通过内部和外部调控重复性急性应激反应后攻击行为的变化。
