Two studies examined the relationship between social comparison orientation (SCO) and two types of closeness (dimensional closeness and psychological closeness) in the context of appearance-related comparisons among women. A pilot study showed that these two types were relatively independent constructs, and provided evidence for the differential validity of the constructs. Consistent with our e...

Using declassified Federal Bureau of Narcotics records on 800 US Mafia members active in the 1950s and 1960s, and on their connections within the Cosa Nostra network, I estimate network effects on gangsters’ economic status. Lacking information on criminal proceeds, I measure economic status exploiting detailed information about their place of residence. Housing values are reconstructed using c...

This research paper explores the relationship between “student-to-other” closeness within a large-scale introductory engineering class and student performance as measured by final grade. Aron and Aron have developed the theory of self-expansion through their work on “including other in the self” (IOS) and have shown that self-expansion can have many benefits including sharing of resources and g...

UNLABELLED In this paper, we highlight the need for acknowledging the importance and impact of both physical and emotional closeness between the preterm infant and parent in the neonatal intensive care unit. Physical closeness refers to being spatially close and emotional closeness to parental feelings of being emotionally connected to the infant (experiencing feelings of love, warmth and affec...

The goal of this work is to identify the nodes that have the smallest sum of distances to other nodes (the lowest closeness centrality nodes) in graphs that evolve over time. Previous approaches to this problem find the lowest centrality nodes efficiently at the expense of exactness. The main motivation of this paper is to answer, in the affirmative, the question, ‘Is it possible to improve the...
