Urban Lighting Research Transdisciplinary Framework—A Collaborative Process with Lighting Professionals
PublikacjaOver the past decades, lighting professionals have influenced the experience of the night by brightly illuminating streets, buildings, skylines, and landscapes 24/7. When this became the accepted norm, a dual perspective on night-time was shaped and the visual enjoyment of visitors after dusk was prioritized over natural nightscapes (nocturnal landscapes). During this time, researchers of artificial light at night (ALAN) observed...

Sustainability reporting in justice systems: a comparative research in two European countries
PublikacjaPurpose – That on accountability in public organizations is quite an old debate. Its introduction in judicial systems is, however, still viewed with some suspicion, due to its potential trade-off with independence and impartiality. Nevertheless, the need to respond to the demands for greater transparency and accountability has also pushed judicial organizations to establish a dialogue with a wide range of subjects. This study aims...

Sustainability reporting in the airline industry: Current literature and future research avenues
PublikacjaSustainability reporting (SR) allows organisations to communicate their non-financial impacts to stakeholders. It has also become a widespread business practice in aviation, a transport sector that contributes significantly to global warming. Academia has begun to examine SR in the context of airlines surprisingly late, and no comprehensive reviews of its respective developments have been made so far. Consequently, a systematic...
