t-Closeness is a privacy model recently defined for data anonymization. A data set is said to satisfy t-closeness if, for each group of records sharing a combination of key attributes, the distance between the distribution of a confidential attribute in the group and the distribution of the attribute in the data is no more than a threshold t. We state here the t-closeness property in terms of i...

This paper implements an estimated ranking algorithm of closeness centrality measures in large-scale workflow-supported social networks. The traditional ranking algorithms for large-scale networks have suffered from the time complexity problem. The larger the network size is, the bigger dramatically the computation time becomes. To solve the problem on calculating ranks of closeness centrality ...

The intrusion of magma into relatively shallow strata often results in structural deformation. Forced folds are typically formed above intrusions so as to accommodate the addition new volumes sedimentary pile. This work uses a high-resolution 3D seismic volume from offshore Taranaki Basin, New Zealand investigate large forced Upper Cretaceous-Paleocene sequences due magmatic dikes and sills. Th...

Social distance (i.e., the degree of closeness to another person) affects the way humans perceive and respond to fairness during financial negotiations. Feeling close to someone enhances the acceptance of monetary offers. Here, we explored whether this effect also extends to the spatial domain. Specifically, using an iterated version of the Ultimatum Game in a within-subject design, we investig...

Bereaved adolescents (N = 90) who had experienced relatively common death losses (e.g., grandparent, friend) completed the Texas Revised Inventory of Grief and the Emotional Closeness Scale and Continuum. Results indicated that present grief was significantly higher for friend than for grandparent death loss. A MANOVA revealed that those in the high closeness group reported significantly higher...

Although both betweenness and closeness centrality are claimed to be important for the effectiveness of someone’s network position, it has not been explicitly studied which networks emerge if actors follow incentives for these two positional advantages. We propose such a model and observe that network dynamics differ considerably in a scenario with either betweenness or closeness incentives com...
