Trends and tradition: Negotiating different cultural models in relation to sustainable craft and artisan production

If the identity of ‘design’ as a practice is contested then the relationship of design and designers to craft and craft practices can be hugely confused. This lack of clarity can encourage non-design based organisations to promote the use of ‘trend forecasting’ as a panacea to the design dilemma associated with craft production for non-traditional markets. Consequently fashion sensitive trends become perceived as the driving force of design-led consumption. In this context how do we understand what ‘trend forecasting’ is and becomes when used in this manner? How does it contribute or not to the sustainability of local design cultures? This paper examines how these challenges have been interrogated and experienced through practice at Masters Level at Central Saint Martins College of Art and Design. It seeks sustainable strategies for design and craft drawing on a diverse range of examples to illustrate contemporary artefacts realised from a diverse range of projects, sources and geographical locations

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
