The betweenness and closeness metrics are widely used metrics in many network analysis applications. Yet, they are expensive to compute. For that reason, making the betweenness and closeness centrality computations faster is an important and well-studied problem. In this work, we propose the framework BADIOS which manipulates the graph by compressing it and splitting into pieces so that the cen...

Empathy is generally thought of as the ability to share the emotional experiences of others. In scientific terms, this is usually operationalized as an ability to vicariously feel others' mental and emotional experiences. Supporting this account, research demonstrates that watching others experience physical pain activates similar brain regions to the actual experience of pain itself. First-han...

This paper presents an averaging method for nonlinear systems defined on Riemannian manifolds. We extend closeness of solutions results for ordinary differential equations onR to dynamical systems defined on Riemannian manifolds by employing differential geometry. A generalization of closeness of solutions for periodic dynamical systems on compact time intervals is derived for dynamical systems...

Research on Jamaican mother-child relationships has had a limited focus on authoritarian parenting styles and selected discipline practices such as corporal punishment. This study examined Jamaican mothers' experiences of closeness and connectedness with their children to provide a holistic perspective on Jamaican-parent-child relationships. Thirty mothers (17 middle class and 13 lower class) l...

We examined the roles of curiosity, social anxiety, and positive affect (PA) and negative affect (NA) in the development of interpersonal closeness. A reciprocal self–disclosure task was used wherein participants and trained confederates asked and answered questions escalating in personal and emotional depth (mimicking closeness–development). Relationships between curiosity and relationship out...

We introduce the problem of polyomino Gray codes, which is the listing of all members of certain classes of polyominoes such 4 that successive polyominoes differ by some well-defined closeness condition (e.g., the movement of one cell). We discuss various 5 closeness conditions and provide several Gray codes for the class of column-convex polyominoes with a fixed number of cells 6 in each colum...

In this paper, we build a theoretical framework for quantitatively measuring and graphically representing the degrees of closeness centralization among performers assigned to enact a workflow procedure. The degree of closeness centralization of a workflow-performer reflects how near the performer is to the other performers in enacting a corresponding workflow model designed for workflow-support...

In this Norwegian study, bidirectional relations between children's behavior problems and child-teacher conflict and closeness were examined, and the possibility of moderation of these associations by child-care group size was tested. Eight hundred and nineteen 4-year-old children were followed up in first grade. Results revealed reciprocal effects linking child-teacher conflict and behavior pr...

Psychological research on the efficacy of torture frequently excludes an important question: What causes people to believe that torture is effective? We investigated whether a factor increasing persons’ desire for torture to be effective might lead them to perceive that it was more effective. Across 2 studies, participants evaluated hypothetical crisis scenarios that varied in the degree of per...
