We present a technique for restructuring functions with low cohesion into functions with high cohesion. Such restructuring is desirable when re-architecting a legacy system into an object-oriented architecture. The restructured system has functions with higher cohesion and hence lower coupling. This enables finer-grained grouping of functions into objects. Automatically decomposing a function i...

Organizations deploy advanced communication media such as audio and videoconferencing to enhance and extend group communication interactions. However, established groups (i.e., groups with a history of working together) can view and use the same technology differently from groups without any past experiences of working together. This study examines the relative influences of media condition and...

Studies on captive bottlenose dolphins, Tursiops truncatus, have shown that each individual produces a stereotyped, individually specific signature whistle; however, no study has demonstrated clear context-dependent usage of these whistles. Thus, the hypothesis that signature whistles are used to maintain group cohesion remains untested. To investigate whether signature whistles are used only i...

This paper models the trade-off between production and appropriation in the presence of simultaneous interand intra-group conflicts. The model exhibits a ‘group cohesion effect ’: if the contest between the groups becomes more decisive, or contractual incompleteness between groups becomes more serious, the players devote fewer resources to the intra-group conflict. Moreover, there is also a ‘re...

Abstract Group cohesion is an important factor in group therapy as it influences treatment outcomes and processes. One’s attachment style has been found to impact experiences of cohesion, however research into this relationship substance use disorder (SUD) lacking. This particular concern insecure presentations are more prevalent clinical population often choice. The current study sought determ...

We present CoMet, a novel approach for computing group’s cohesion and using that to improve robot’s navigation in crowded scenes. Our uses cohesion-metric builds on prior work social psychology. compute this metric by utilizing various visual features of pedestrians from an RGB-D camera on-board robot. Specifically, we detect characteristics corresponding the proximity between people, their rel...
