Title (down) Under the Cover of Darkness: How Ambient Light Influences Criminal Activity Type Journal Article
Year 2015 Publication Review of Economics and Statistics Abbreviated Journal Review of Economics and Statistics
Volume 97 Issue 5 Pages 1093-1103
Keywords Public Safety; Crime
Abstract We exploit daylight saving time (DST) as an exogenous shock to daylight, using both the discontinuous nature of the policy and the 2007 extension of DST, to consider the impact of light on criminal activity.Regression discontinuity estimates show a 7% decrease in robberies following the shift to DST. As expected, effects are largest during the hours directly affected by the shift in daylight. We discuss our findings within the context of criminal decision making and labor supply, and estimate that the2007 DST extension resulted in $59 million in annual social cost savings from avoided robberies.

Title (down) Unawareness in environmental protection: The case of light pollution from traffic Type Journal Article
Year 2012 Publication Land Use Policy Abbreviated Journal Land Use Policy
Volume 29 Issue 3 Pages 598-604
Keywords Public Safety; public policy; traffic safety
Abstract New information is often emphasized as a basis of effective and scientifically sound environmental policy and management. However, outdated or incorrect information is not automatically nor instantly replaced by new insights. This article focuses on the various ways environmental information can be unintentionally left with insufficient attention or purposefully neglected. Energy-related emissions caused by road traffic in Finland are used as an illustrative example and light pollution caused by artificial lighting is identified as an emerging issue that has gained especially low recognition in the environmental agenda. Four different reasons for this lack of recognition are discussed: recognized unawareness, false awareness, deliberate unawareness and concealed awareness. Paying attention to light pollution is important because of various ecological, socio-cultural and economic effects but also because implementing measures aimed for reducing light pollution create possibilities for alleviating other social and environmental problems in transport and land use policies.

Title (down) Two-stream approximation for rapid modeling the light pollution levels in local atmosphere Type Journal Article
Year 2012 Publication Astrophysics and Space Science Abbreviated Journal Astrophys Space Sci
Volume 341 Issue 2 Pages 301-307
Keywords Light pollution; Atmospheric effects; Methods: numerical; Radiative transfer; Scattering; modeling; two-stream approximation
Abstract The two-stream concept is used for modeling the radiative transfer in Earth's atmosphere illuminated by ground-based light sources. The light pollution levels (illuminance and irradiance) are computed for various aerosol microphysical parameters, specifically the asymmetry parameter g A , single scattering albedo ω A , and optical thickness τ A . Two distinct size distributions of Junge's and gamma-type are employed. Rather then being a monotonic function of τ A , the diffuse illuminance/irradiance shows a local minimum at specific τ A, lim independent of size distribution taken into consideration. The existence of local minima has relation to the scattering and attenuation efficiencies both of which have opposite effects. The computational scheme introduced in this paper is advantageous especially if the entire set of calculations needs to be repeated with an aim to simulate diffuse light in various situations and when altering optical states of the atmospheric environment.
