In the competitive environment of academia, research strategies and productivity are key. However, for marginalised researchers with intersecting mechanisms of oppression, these strategies face challenges particularly in Physics, Technology, Engineering and Mathematics (pSTEM) fields where women are often underrepresented and research is geographically concentrated. Our goal is to understand and enhance the scientific impact of these less privileged groups, contributing to their epistemic reparation. We examine research as a cooperative process developed by communities in co-authorship networks. We focus on the intersection of segregation, core-periphery position, and socio-demographic diversity within Computer Science communities, and their relation to visibility and success. Using the Spectral Segregation Index (SSI), we categorise communities based on levels of segregation and core positions. Our findings show a correlation between a community’s segregation category, core-periphery structure, and citation count. Highly cited papers from non-segregated communities are less diverse and centrally located. Conversely, highly diverse but less cited papers come from segregated and peripheral communities. Our results entitle the need for strategies to enhance the visibility of diverse, peripheral work, particularly from underrepresented groups, considering the co-authorship network’s constraints for a fairer scientific landscape.

Effect of sink layer thickness on damping in CoMnGe (5 nm) / Ag (6 nm) / NiFe (x nm) spin valves
Valkass, Robert Alexander James; Shelford, Leigh R; Durrant, Chris J; et al. (University of Exeter, 4 April 2016)In spin valve structures the damping of a ferromagnetic layer driven at resonance can be modified by the transfer of spin angular momentum into a ‘sink’ ferromagnetic layer. This effect, known as spin pumping, is interface ... -
Impacts of Revised Geologic Forcing Factors on the Phanerozoic Carbon Cycle
Williams, Joshua James (University of Exeter Geography, 21 July 2016)Traditionally, biogeochemical models are forced by the 87Sr/86Sr, δ13C and/or δ34S isotopic records. This study builds on existing work to present a forwards model for the entire Phanerozoic that aims instead to predict ... -
