Title A comparison between emergence and return activity in pipistrelle bats Pipistrellus pipistrellus and P. pygmaeus Type Journal Article
Year 2006 Publication Acta Chiropterologica Abbreviated Journal
Volume 8 Issue 2 Pages 381-390
Keywords animals; fying mammals: animal behaviour
Abstract Bats may be vulnerable to predation during evening emergence and morning return to their roosts. Early emergence increases the risk of exposure to raptorial birds, but emerging late confers a risk of missing the dusk peak of aerial insects. Here, both emergence and return activity was studied in detail at the same roosts for the first time. We investigated six maternity colonies of pipistrelle bats (Pipistrellus pipistrellus and P. pygmaeus) in NE Scotland and recorded light levels and time of emergence and return of the bats with respect to sunset and sunrise on the same nights. Parameters of return activity generally occurred at lower light intensities than those of emergence. Therefore, the interval between dawn return and sunrise was generally longer than that between sunset and dusk emergence. Emergence and return were equal in duration. Bats clustered more on emergence in comparison with return during pregnancy and lactation, whereas during postlactation this trend was reversed.

Title The use and misuse of coloured light in the urban environment Type Journal Article
Year 2006 Publication Optics & Laser Technology Abbreviated Journal Optics & Laser Technology
Volume 38 Issue 4-6 Pages 366-376
Keywords Planning; Society; Psychology
Abstract The last few years have seen a huge increase in the transfer of coloured architectural lighting, derived from entertainment and theatre, into the urban and exterior environment. Part of the reason for this is that in the last 15 yr or so, there have been a number of important introductions in coloured lighting technology. These have transformed lighting practice, and while their widespread introduction is seen by some as an enrichment of the urban fabric, others see it as presenting considerable dangers, in terms of aesthetics, perception and in terms of civic identity. Its negative effects on the urban environment have been termed ‘colour blight’.

In this paper, the range of coloured lighting technologies is surveyed and other causes for the increase in coloured lighting are also discussed, together with the problems and benefits involved. Finally, some tentative means are put forward for resolving the problems caused by ‘colour blight’. Current good practice is illustrated by the author's own experience, including his consultancy's participation in a number of urban lighting strategies in the UK and elsewhere. This work involves implementation of a comprehensive lighting plan for the historic city of York, as part of the Urban Lighting Group consortium of three lighting design practices.

Title A survey of the luminance distribution in the nocturnal environment in Shanghai urban areas and the control of luminance of floodlit buildings Type Journal Article
Year 2006 Publication Lighting Research & Technology Abbreviated Journal Lighting Research & Technology
Volume 38 Issue 3 Pages 185-189
Keywords Lighting
Abstract A survey of the luminance distribution of the nocturnal environment in Shanghai urban areas, which included 11 locations and 16 buildings, was made. The 11 locations could be categorized as commercial, administration, leisure or residential. The average environmental luminance of these was recorded. The authors identified the effects of excessive exterior lighting. The luminance was measured and subjective appraisals made of 16 buildings. The writers have developed an empirical formula for arriving at the brightness level rating for floodlit buildings and recommended corresponding working ranges of luminance.

Title A Model for Nighttime Urban Illumination Type Journal Article
Year 2006 Publication Abbreviated Journal
Volume Issue Pages
Keywords Skyglow
Abstract The Army increasingly relies on night operations to accomplish its objectives. These night operations frequently require using Night Vision Goggles and other light-sensitive devices which are strongly affected by ambient lighting, a large component of which is urban. An urban illumination model is proposed for use in tactical decision aids and wargames which would allow for more accurate prediction of target acquisition ranges and increased realism in simulations. This model will build on previous research that predicts broadband brightness as a function of population and distance from the city center. Since city population and aerosols affect light distributions, the model is being extended and generalized for multiple city types and natural and man-made aerosols. An overview of the model along with future improvements will be presented.
