| Abstract |
Light pollution is a negative lighting condition because it prevents views of the night sky from the general population and astronomers. As a solution to light pollution, proper lighting system design is vital. The location, mounting height, and aim of exterior luminaries need to be taken into consideration for efficient use of lighting energy. In line with the effort, this paper presents the assessment results on light pollution at the port area, which is one of the brightest spots on Earth. In doing so, a GIS model is created to determine the level of light pollution at the study areas. The lighting power densities of ASHRAE 90.1-2007 are applied in order to find a way to reduce the level of light pollution. The effect of light pollution generated from the Long Beach Port area is examined by comparing against the sky glow generated from the Port of Long Beach area and other areas throughout the coast of Southern California, as well as comparing how deep the sky glow penetrates the ocean. The results are validated by comparing against the lighting specification used in the study areas. The lighting strategies proposed include the decreased height of light poles and increased spacing between light poles. This study will serve as a platform in which future researchers may continue and expand on the designs of heights and spaces of lighting poles in order to make severe light pollution areas better sustainable places. |

| Abstract |
The NixNox procedure to build all-sky maps of the nocturnal night sky brightness using SQM photometers is described. Astronomers belonging to amateur associations in Spain are using this observational method to obtain data of their preferred sites of observation to characterize the astronomical quality of the sky and the sources of light pollution. |

| Abstract |
Artificial lighting is strongly associated with urbanisation and is increasing in its extent, brightness and spectral range. Changes in urban lighting have both positive and negative effects on city performance, yet little is known about how its character and magnitude vary across the urban landscape. A major barrier to related research, planning and governance has been the lack of lighting data at the city extent, particularly at a fine spatial resolution. Our aims were therefore to capture such data using aerial night photography and to undertake a case study of urban lighting. We present the finest scale multi-spectral lighting dataset available for an entire city and explore how lighting metrics vary with built density and land-use. We found positive relationships between artificial lighting indicators and built density at coarse spatial scales, whilst at a local level lighting varied with land-use. Manufacturing and housing are the primary land-use zones responsible for the city's brightly lit areas, yet manufacturing sites are relatively rare within the city. Our data suggests that efforts to address light pollution should broaden their focus from residential street lighting to include security lighting within manufacturing areas. |

| Abstract |
Humans are a diurnal species usually exposed to light while engaged in cognitive tasks. Light not only guides performance on these tasks through vision but also exerts non-visual effects that are mediated in part by recently discovered retinal ganglion cells maximally sensitive to blue light. We review recent neuroimaging studies which demonstrate that the wavelength, duration and intensity of light exposure modulate brain responses to (non-visual) cognitive tasks. These responses to light are initially observed in alertness-related subcortical structures (hypothalamus, brainstem, thalamus) and limbic areas (amygdala and hippocampus), followed by modulations of activity in cortical areas, which can ultimately affect behaviour. Light emerges as an important modulator of brain function and cognition. |
