Copying, emergence, and digital reproduction

This talk combines concepts of the copying of manuscripts in the age before mechanical reproduction (as described in W. Benjamin’s famous Artwork-essay), of the emergence of non-vertical evolution (as to be found in textual ‘contamination’ and in horizontal gene transfer alike), and of the electronic reproduction of such phenomena (as presented in scholarly digital editions and phylogenetic trees). The guiding idea is that ‘copying’, ‘emergence’, and ‘(digital) reproduction’ enable variation depending on particular physical or biological forms, on contextual or environmental conditions, as well as on user habits or receptive fields. – Is it possible to develop a theory of copying and reproduction on this base? The material of the talk will be drawn from the Parzival-Project, a critical electronic edition of an Arthurian romance, composed by the German poet Wolfram von Eschenbach shortly after 1200 and transmitted in over eighty witnesses.

An (un) healthy poster: When environmental cues affect consumers’ food choices at vending machines

Environmental cues can affect food decisions. There is growing evidence that environmental cues influence how much one consumes. This article demonstrates that environmental cues can similarly impact the healthiness of consumers’ food choices. Two field studies examined this effect with consumers of vending machine foods who were exposed to different posters. In field study 1, consumers with a health-evoking nature poster compared to a pleasure-evoking fun fair poster or no poster in their visual sight were more likely to opt for healthy snacks. Consumers were also more likely to buy healthy snacks when primed by an activity poster than when exposed to the fun fair poster. In field study 2, this consumer pattern recurred with a poster of skinny Giacometti sculptures. Overall, the results extend the mainly laboratory-based evidence by demonstrating the health-relevant impact of environmental cues on food decisions in the field. Results are discussed in light of priming literature emphasizing the relevance of preexisting associations, mental concepts and goals.
