769: Our latest episode features a panel from our Metis Strategy Digital Symposium in May 2023 where Michael and Rob discuss the topic of design thinking in ecosystem business models. Michael explains how he brings design thinking into ArcBest as a mechanism to drive innovation and the role ArcBest Technologies plays in ArcBest's innovation ecosystem. Rob details the innovation cycle within Broadridge and how he brings the customer's voice into that cycle to ensure continuous value is getting delivered. Finally, both executives speak on driving centralized innovation within their ecosystems and deploying those innovations to internal and external customers.Also available on YouTube:https://youtu.be/cOq6BxPIDf0_____________________________________This episode is sponsored by Quantiphi.

With the installation of the Cosmic Origins Spectrograph on the Hubble Space Telescope, measurements of the metal content of the low redshift intergalactic medium (IGM) are now available. Using a new grid-based model for diffuse gas coupled to the SAGE semi-analytic model of galaxy formation, we examine the impact of supernova feedback on the pollution of the IGM. We consider different assumptions for the reheating and ejection of gas by supernovae and their dependence on galaxy circular velocity and gas surface density. Where metals are present, we find the most likely metallicity to be $-1.5 < $log$_{10}$(Z/Z$_{\odot}$)$ < -1.0$ at $z = 0$, consistent with both observations and more sophisticated hydrodynamic simulations. Our model predicts that the regions of the IGM with the highest metallicities will be near galaxies with M$_{\star} \sim 10^{10.5}h^{-1}$M$_{\odot}$ and in environments of densities $\sim 10 \times$ the mean. We also find that 90% of IGM metals at $z = 0$ are ejected by galaxies with stellar masses less than $10^{10.33}h^{-1}$M$_{\odot}$.
