3ON CLASSES OF REGULAR GRAPHS WITH CONSTANT METRIC DIMENSION显示文摘In this paper,we are dealing with the study of the metric dimension of some classes of regular graphs by considering a class of bridgeless cubic graphs called the flower snarks Jn,a class of cubic convex polytopes considering the open problem raised in [M.Imran et al.,families of plane graphs with constant metric dimension,Utilitas Math.,in press] and finally Harary graphs H 5,n by partially answering to an open problem proposed in [I.Javaid et al.,Families of regular graphs with constant metric dimension,Utilitas Math.,2012,88:43-57].We prove that these classes of regular graphs have constant metric dimension.Muhammad IMRAN Syed Ahtsham ul Haq BOKHARY Ali AHMAD Andrea SEMANIOV-FENOVíKOV 2013Acta Mathematica Scientia2013,33,1:0
4休闲涉入与旅游目的地吸引力:地方依恋的中介作用——基于空间的生产理论显示文摘既有文献显示,从旅游目的地空间生产者视角研究空间建构机理颇受关注。本研究从演艺节事旅游消费者——游客的视角,运用“休闲活动——空间情感化——空间建构”的研究框架,提出“休闲涉入——地方依恋——旅游目的地吸引力”的理论模型;并利用2018年度上海超级草莓音乐节现场回收的279份有效问卷,通过探索性因子分析、验证性因子分析以及回归分析等方法验证了上述理论模型。尹卫华 华玉 2020上海建桥学院学报2020,,3:0
