Using the Co-design Process to Build Non-designer Ability in Making Visual Thinking Tools

This research is a case study of using co-design as a way of assisting the capacity building process for an Indianapolis-based community organizer. The community organizer seeks to develop a visual thinking tool for enhancing her engagement with community participants. Community organizers face a wide array of complicated challenges, addressing these kinds of challenges and social issues calls for innovative and inclusive approaches to community problem solving. The author hopes this case study will showcase itself as an example of leveraging design thinking and visual thinking to support and equip more first-line workers who are non-designers to do their community jobs with a more creative problem-solving approach

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
