Fluid Tasks and Fluid Teams: The Impact of Diversity in Experience and Team Familiarity on Team Performance
In this paper, we consider how the structures of tasks and teams interact to affect team performance. We study the effects of diversity in experience on a team's ability to respond to task changes, by separately examining interpersonal team diversity (i.e., differences in experience across the entire team) and intrapersonal team diversity (i.e., whether individuals on the team are more or less specialized). We also examine whether team familiarity - team members' prior experience working with one another - helps teams to better manage challenges created by task changes and greater interpersonal team diversity. Using detailed project- and individual-level data from an Indian software services firm, we find that the interaction of task-change with intrapersonal diversity is related to improved project performance, while the interaction of task-change with interpersonal diversity is related to diminished performance. Additionally, the interaction of team familiarity with interpersonal diversity is related to improved project performance in some cases. Our results highlight a need for more nuanced approaches to leveraging experience in team management.Diversity, Knowledge Work, Project Flexibility, Task Change, Team Familiarity

Instabilities and soot formation in spherically expanding, high pressure, rich, iso-octane-air flames
Flame instabilities, cellular structures and soot formed in high pressure, rich, spherically expanding iso-octane-air flames have been studied experimentally using high speed Schlieren cinematography, OH fluorescence, Mie scattering and laser induced incandescence. Cellular structures with two wavelength ranges developed on the flame surface. The larger wavelength cellular structure was produced by the Landau-Darrieus hydrodynamic instability, while the short wavelength cellular structure was produced by the thermal-diffusive instability. Large negative curvature in the short wavelength cusps caused local flame quenching and fracture of the flame surface. In rich flames with equivalence ratio φ > 1.8, soot was formed in a honeycomb-like structure behind flame cracks associated with the large wavelength cellular structure induced by the hydrodynamic instability. The formation of soot precursors through low temperature pyrolysis was suggested as a suitable mechanism for the initiation of soot formation behind the large wavelength flame cracks
