Title Sustainable Governance of the Urban Night Type Journal Article
Year 2019 Publication Nauchni trudove Abbreviated Journal
Volume 1 Issue Pages 219-233
Keywords Planning; Society; Sustainability; Conservation
Abstract Since humans are day active primates the differences between day and night seem to be so deeply rooted that a holistic, integrative view of the 24 hours cycle of the city is far from being established. Notwithstanding all the topical talking about the 24/7 city, the analysis of cities and their governance focuses mainly on the day, even if we witness an increasing “colonization of the world after dark” (Melbin, 1987). This extension of activity into the night is producing a growing number of conflicts.

Title Of husbandry Type Journal Article
Year 70 Publication Abbreviated Journal
Volume Book 9 Issue Pages
Keywords Animals
Abstract Excerpt from Chapter 14, page 409 in the linked English translation:

...Therefore, at the time when the mallows blossom, when there is the greatest multitude of these butterflies, if a high brazen vessel, with a narrow neck like the mile-column, be placed in the evening among the bee-hives, and some light put down to the bottom of it, the butterflies gather together to it from all places; and, while they flutter about the small flame, they are scorched, because they can neither fly easily upward out of the narrow place, nor, on the other hand, can they retire at a greater distance from the fire, since they are surrounded by the sides of the brazen vessel: therefore they are consumed by the burning heat that is near them...

Title Testing for changes in light emissions from certified International Dark Sky Places Type Journal Article
Year 2019 Publication International Journal of Sustainable Lighting Abbreviated Journal
Volume 21 Issue 1 Pages 11-19
Keywords Remote Sensing; Conservation; Policy
Abstract The International Dark-Sky Places (IDSP) program of the International Dark-Sky Association is a voluntary certification in which communities commit via legislative changes to move towards more sustainable lighting that reduces light pollution. As over 115 IDSP have now been certified, it is interesting to ask the extent to which this certification results in reduced light emissions. In this paper, we compared trends in upward light emission of 98 communities located in or near IDSP to those of 98 similarly sized communities further away from the IDSP, using a night lights observing satellite (the Visible Infrared Imaging Radiometer Suite Day-Night Band). The current dataset is not sufficient to distinguish the hypothesis that IDSP certification results in a lower rate of change in upward light emissions from the null hypothesis that IDSP certification has no impact. This result is with regard to upward light emissions only: it is possible that certification has resulted in decreases in night sky brightness that the satellite is not able to observe.

Title Illumination at twilight Type Journal Article
Year 1963 Publication Okios Abbreviated Journal
Volume 14 Issue 1 Pages 9-21
Keywords Animals; Instrumentation; Methods
Abstract Introduction Poikilotherms with a nocturnal or crepuscular period of activity are usually guided by changes in illumination. The releasing factor may be a certain low level of illumination, or it might be a certain rate of change of intensity or a combination of both. ASCHOFF (1960) has shown that also animals with an internal clock mechanism of activation have to have the “clock” reset by actual changes in illumination. To all students of such animals it is essential to measure light intensity and its changes especially during the twilight period.

Title Light Pollution at Mount Wilson and at Palomar in 1931-32 Type Journal Article
Year 2002 Publication The Observatory Abbreviated Journal
Volume 122 Issue Pages
Keywords Skyglow
Abstract I present a short summary of an unpublished letter by Joel Stebbins on light pollution at Mount Wilson Observatory and on Palmar Mountain in 1931-32. I analyzed his results and show that the light emission per capita in 1932 – o was about 3*1*10^17 photons s^-1 in the blue region, equivalent to about 220 lumens per head in the visual region. These my be compared with about 1*4*10^18 photons s^-1 in the blue region and about 1000 lumens per head in the visual region for California cities in 1970.
