An old debate about the excitability of the neural myelin sheath, which was fought in Europe between the world wars of the last century, has been settled. Schwann cells are active players in excitation conduction! A study by G. David provides sufficie

Abstract In the context of environmental sustainability, food waste is a major challenge. Digitalization and especially the proliferation of smartphones suggest the use of mobile apps to address food waste. One of the most important apps in Europe and the US is Too Good To Go. However, consumer intentions to use apps like Too Good To Go are largely unexplored. Based on a survey of 380 respondents in Germany, this paper uses a structural equation model to investigate the influence of sustainable consumption consciousness, price consciousness, and hedonic benefits on the intention to use apps against food waste. The results show that neither sustainable consumption consciousness nor price consciousness significantly influence the intention to use apps against food waste. Users use apps against food waste mainly for hedonic reasons. The results indicate that not only users with sustainable consumption consciousness are willing to use apps against food waste in the interest of sustainability. This research paper therefore makes an important contribution for companies in the food sector to better understand the intentions of consumers who use mobile apps to combat food waste. Furthermore, the paper provides important insights for developers of such apps for future development.

The purpose of this paper is to better understand how responsible entities like people, organizations, regional governments can approach their learning and development strategies [15]. Despite all the heterogeneity in the respective “run-transform-innovate” contexts of the different responsible entities, they all have in common that they have to become “better future versions of themselves” to overcome their challenges [40]. Using the example of organizations, the concept of Service Innovation Roadmaps (SIR’s) is introduced to broaden a discussion in this area that has so far been very technology-focused [15, 28, 40]. In order to identify and take into account new dimensions and to give greater consideration to other nontechnological aspects as well, the research design of “theory adaptation” is chosen [16].

Abstract AimLichens and mosses play important functional roles in all terrestrial ecosystems, particularly in tundra and drylands. As with all taxa, to maintain their current niche in a changing climate, lichens and mosses will have to migrate. However, there are no published estimates of future habitat suitability or necessary rates of migration for members of these groups at the global scale.TaxonLichens and mosses.LocationGlobal.MethodsUsing global occurrence data, we conducted ensemble distribution models in the ‘biomod2’ R package, parameterised with a range of climatic, land use and soil variables, to estimate current and future (2100) habitat suitability in 16 abundant species of lichen and moss.ResultsWithout considering dispersal limitation, suitable area was forecast to expand for eight species and decline for four species. For species with predominantly boreo‐arctic distributions, suitable area typically declined at the temperate range edge and expanded across the High Arctic. Future suitable area available to dryland‐adapted species generally declined overall, likely relating to the desiccation‐tolerant physiology of lichens and mosses. The average migration rates required for species to disperse into new suitable habitat ranged from 1.7 (Placidium squamulosum) to 9.0 km year−1 (Syntrichia ruralis), although most species will need to migrate >16 km year−1 to completely fill their potential future suitable habitat.Main ConclusionsFor mosses and lichens, as with all species, migration will be an important part of the adjustment to a warmer climate, but realisation of these potential migrations will require both rare dispersal events and habitat that is suitable in non‐climatic dimensions. Current evidence on dispersal in these groups suggests that these geographical shifts may be unlikely to be realised without intervention, especially in landscapes that are highly modified by humans.
