Twenty Years of the Polyvinyl Chloride Sustainability Challenges

Intense campaigning pressure on the UK PVC sector up to the late 1990s forced strategic engagement with sustainable development. Simplified outcomes from a detailed, consensus-based analysis by science-based NGO The Natural Step (TNS) took the form of five TNS Sustainability Challenges for PVC published in 2000. UK manufacturing companies initially used these Challenges to direct strategic progress. The Challenges have since been progressively taken up across European PVC value chains. The VinylPlus® programme uses an updated version of the five Challenges as a basis for voluntary commitments and transparent auditing of progress against published targets. Initial framing of the five TNS Sustainability Challenges for PVC were drafted consciously for generic relevance to other materials. Assessing the sustainability performance of some alternative materials to PVC against the five Sustainability Challenges reveals different sustainability performance in a range of potential applications. This highlights the danger inherent in automatic selection or deselection of materials in the absence of assessment of options on a ‘level playing field’ of sustainability principles. The five TNS Sustainability Challenges for PVC remain valid today and into the longer-term future as a basis for making stepwise, profitable progress towards the goal of sustainability for PVC and other materials

“Arseing around was fun!”:humor as a resource in design and making

Abstract Humor is an inevitable part of human life. Most of us are capable of experiencing and appreciating humor. From this perspective, surprisingly little HCI research can be found scrutinizing the existence, role, and potential of humor in our design practice. The gap remains also related to children and teenagers; there is a lack of studies appreciating the emergence and existence of humor in the design process without intentionally evoking it. Thus, this study examines humor as a naturally occurring phenomenon in the design process. The study was conducted in collaboration with a class of teenagers and their teachers. The study identifies various forms and functions of humor in the design process and reveals its situated, emergent nature as a resource in interaction within design. The study proposes a practical tool for designers for anticipating and potentially facilitating the emergence, forms and usages of humor as an interactional resource in design
