Urban Centrality: A Simple Index
Geographical Analysis, 2012This study introduces a new measure of urban centrality. The proposed urban centrality index (UCI) constitutes an extension to the spatial separation index. Urban structure should be more accurately analyzed when considering a centrality scale (varying from extreme monocentricity to extreme polycentricity) than when considering a binary variable ...

An improved index of centrality
Behavioral Science, 1965Increasing interest in the application of graph theory to the behavioral sciences is evidenced by the 1963 publication of the book “Applications of Graph Theory to Group Structure” by Claude Flament. Discussed there is the meaning and limitations of the Bavelas measure of centrality.

Network centralization with the Gil Schmidt power centrality index
Social Networks, 2009Abstract Network centralization is a network index that measures the degree of dispersion of all node centrality scores in a network from the maximum centrality score obtained in the network. The Gil Schmidt power centrality index was developed for use in describing the political networks of Mexico, Gil and Schmidt [Gil, J., Schmidt, S., 1996a.

Toward a Centrality Index for Computing Grids
2012The computing grid has emerged as an attractive field in Computer Science. However, little attention has focused on the centrality of each computing grid. In this article, we suggest a Centrality Index based on the economist and geographer Walter Christaller’s Central Place Theory.

Central Field Index Versus Visual Field Index for Central Visual Function in Stable Glaucoma
Journal of Glaucoma, 2017Objective: To compare the variability of central field index (CFI) versus visual field index (VFI) in stable glaucoma with central fixation involvement. Materials and Methods: For this retrospective study, we identified multiple visual fields (VFs) of patients with repeatable ...

The effect of HSR connection on urban cluster centrality: evidence from China
Applied Economics, 2021In a time varying difference-in-differences setting, we empirically test the impact of high-speed rail (HSR) connections on urban clusters in China. We construct an urban cluster centrality index to reflect changes in the economic positions of counties ...

Index of central obesity – A novel parameter
Medical Hypotheses, 2007Waist circumference (WC) is globally used as a parameter to quantify central obesity, the key culprit in insulin resistance and related disorders. Hitherto globally in various definitions of metabolic syndrome and risk scores, WC is used to quantify central obesity.
