On Finite Metahamiltonian p-Groups
Lijian An,Qinhai Zhang
Mathematics , 2014,
Abstract: A group is called metahamiltonian if all non-abelian subgroups of it are normal. This concept is a natural generalization of Hamiltonian groups. In this paper, the properties of finite metahamiltonian $p$-groups are investigated.
Finite $p$-groups with a minimal non-abelian subgroup of index $p$ (IV)
Lijian An,Ruifang Hu,Qinhai Zhang
Mathematics , 2013, DOI: 10.1142/s0219498814500327
Abstract: In this paper, we completely classify the finite $p$-groups $G$ such that $\Phi(G')G_3\le C_p^2$, $\Phi(G')G_3\le Z(G)$ and $G/\Phi(G')G_3$ is minimal non-abelian. This paper is a part of the classification of finite $p$-groups with a minimal non-abelian subgroup of index $p$. Together with other four papers, we solve a problem proposed by Y. Berkovich.
Finite $p$-groups all of whose subgroups of index $p^3$ are abelian
Qinhai Zhang,Libo Zhao,Miaomiao Li,Yiqun Shen
Mathematics , 2014,
Abstract: Suppose that $G$ is a finite $p$-group. If all subgroups of index $p^t$ of $G$ are abelian and at least one subgroup of index $p^{t-1}$ of $G$ is not abelian, then $G$ is called an $\mathcal{A}_t$-group. In this paper, some information about $\mathcal{A}_t$-groups are obtained and $\mathcal{A}_3$-groups are completely classified. This solves an {\it old problem} proposed by Berkovich and Janko in their book. Abundant information about $\mathcal{A}_3$-groups are given.

系统科学与数学 , 2005,
Abstract: A direced Cayley graph $X=\cay(G, S)$ is called normal for $G$ if the right representation $R(G)$ of $G$ is normal in the full automorphism group $\Aut (X)$. In this paper, we determine all non-normal directed Cayley graphs of finite abelian groups with valencies 2 and 3. Using the result, we give a complete classification of connected directed arc-transitive graphs of order $p^n$ ($n\leq 2, p$ an odd prime) with valency at most 3.

Abstract: 摘要 通过综合运用程序化扎根理论、关键事件和问卷调查等研究方法探讨了服务消费情境下消费者幸福感的构念开发和驱动因素问题。研究发现消费者幸福感包括两个核心维度,即满足感和积极情感。驱动消费者幸福感的因素包括人际因素(服务人员和其他顾客)和非人际因素(产品/服务和服务氛围),其中人际因素-服务人员对顾客满足感和积极情感的效用发挥最大,其次为其他顾客,服务氛围和产品/服务。
How to gain loyalty by strengthening consumer well-being has gained considerable attention of scholars and practitioners, which has also become an essential research topic within management, marketing and psychology fileds. Through applying methods of grounded theory, critical event technique, and questionnaire survey, this study aimed to develop its construct and then identify drivers of consumer well-being. It was found that consumer well-being included two dimensions, namely satisfaction and positive affect. Drivers of consumer well-being included interpersonal factors (service employee and other customers) and non-interpersonal factors (product/service and service atmosphere). Interpersonal factor-service employee had the biggest effect on consumer well-being, followed by other customers, service atmosphere and product/service

环境科学学报 , 1997,
Abstract: 研究了稀土元素镧对金鱼藻叶绿素总量、抗坏血酸氧化酶、过氧化氢酶、过氧化物酶等代谢指标和细胞叶绿体亚显微结构的影响,以及金鱼藻对镧的吸收积累作用,结果表明,短期内低浓度(2-110mg/L)的镧对金鱼藻生长有一定刺激促进作用,但随处理时间的延长及处理浓度的提高,抑制作用明显增强,并破坏细胞叶绿体结构;金鱼藻对镧有较强的吸收积累能力。

环境科学 , 1996,
Abstract: It was studied that effects of rare-earth elements (La,Ce, Pr, Nd and their mixture) on growth and reproduction of Chlorella pyrenoides. The results showed that effects of rare-earth elements on growth and reproduction of Chlorella pyrenoides were not apparent under lower concentration (2mg/L), but it was inhibited as the concentration increased; and the toxicity (EC50,96 h.) of rareearth elements on Chlorella pyreaoides was insequence as:Nd>Ce>Pr>La>mixture of them, but little difference.

Abstract: 摘要 从一线员工、实施不当行为顾客和同属顾客三者互动角度出发,考察一线员工应对顾客不当行为的能力对同属顾客的感知服务质量与忠诚的影响,并检验同属顾客感知道义公平的中介作用以及顾客不当行为类型的调节作用。采用问卷调查法,通过问卷星网络平台收集数据。研究结果表明,一线员工应对顾客不当行为的能力正向影响同属顾客感知服务质量和忠诚,道义公平的中介作用显著;顾客不当行为类型的调节作用显著,当顾客不当行为的作用对象是同属顾客时,员工应对能力对道义公平的影响更强
