| Title | Bright environmental light improves the sleepiness of nightshift ICU nurses | Type | Journal Article | ||
| Year | 2018 | Publication | Critical Care (London, England) | Abbreviated Journal | Crit Care |

| Abstract | BACKGROUND: Shift work can disturb circadian homeostasis and result in fatigue, excessive sleepiness, and reduced quality of life. Light therapy has been shown to impart positive effects in night shift workers. We sought to determine whether or not prolonged exposure to bright light during a night shift reduces sleepiness and enhances psychomotor performance among ICU nurses. METHODS: This is a single-center randomized, crossover clinical trial at a surgical trauma ICU. ICU nurses working a night shift were exposed to a 10-h period of high illuminance (1500-2000 lx) white light compared to standard ambient fluorescent lighting of the hospital. They then completed the Stanford Sleepiness Scale and the Psychomotor Vigilance Test. The primary and secondary endpoints were analyzed using the paired t test. A p value <0.05 was considered significant. RESULTS: A total of 43 matched pairs completed both lighting exposures and were analyzed. When exposed to high illuminance lighting subjects experienced reduced sleepiness scores on the Stanford Sleepiness Scale than when exposed to standard hospital lighting: mean (sem) 2.6 (0.2) vs. 3.0 (0.2), p = 0.03. However, they committed more psychomotor errors: 2.3 (0.2) vs. 1.7 (0.2), p = 0.03. CONCLUSIONS: A bright lighting environment for ICU nurses working the night shift reduces sleepiness but increases the number of psychomotor errors. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03331822 . Retrospectively registered on 6 November 2017. |

| Title | Photons without borders: quantifying light pollution transfer between territories | Type | Journal Article | ||
| Year | 2018 | Publication | International Journal of Sustainable Lighting | Abbreviated Journal | |
| Volume | 20 | Issue | 2 | Pages | 51-61 |
| Keywords | Skyglow | ||||
| Abstract | The light pollution levels experienced at any given site generally depend on a wide number of artificial light sources distributed throughout the surrounding territory. Since photons can travel long distances before being scattered by the atmosphere, any effective proposal for reducing local light pollution levels needs an accurate assessment of the relative weight of all intervening light sources, including those located tens or even hundreds of km away. In this paper we describe several ways of quantifying and visualizing these relative weights. Particular emphasis is made on the aggregate contribution of the municipalities, which are -in many regions of the world- the administrative bodies primarily responsible for the planning and maintenance of public outdoor lighting systems. | ||||

| Title | The effect of age on white light perception | Type | Journal Article | ||
| Year | 2018 | Publication | International Journal of Sustainable Lighting | Abbreviated Journal | |
| Volume | 20 | Issue | 2 | Pages | 29-43 |
| Keywords | Vision; Psychology | ||||
| Abstract | The way that persons from different age groups experience “white light” is investigated. Human eye lens transmission changes spectrally with age and this may influence the way that humans from different ages experiences light. Such a difference may be important in industrial and medical environments. Two different age groups, one group younger than 40 years of age and another group older than 50 years of age were subjected to the same “white” definition task.A conventional single-booth setup was used where observers were able to adjust the intensity of four coloured LED’s.Results of the psychophysical test procedure were used to generate specifications of two light sources, as selected by the two age groups. The two age groups selected different light sources when tasked to achieve a “perception” of white. Results show that the older group prefers a source with a colour rendering index number of 89 and the younger group prefers a source with a colour rendering index number of 74. The sources selectedby the two age groups specifycorrelated colour temperature values of 5150 K for the older age group and 6592 K for the younger group. | ||||

| Title | Seismic Indirect Economic Loss Assessment and Recovery Evaluation Using Night-time Light Images – Application for Wenchuan Earthquake | Type | Journal Article | ||
| Year | 2018 | Publication | Natural Hazards and Earth System Sciences | Abbreviated Journal | |
| Volume | In press | Issue | Pages | ||
| Keywords | Remote Sensing; Economics | ||||
| Abstract | Seismic indirect economic loss not only has a major impact on regional economic recovery policies, but also related to the economic assistance at the national level. Due to the Cross-regional economic activities and the difficulty of obtaining data, it's difficult that the indirect economic loss survey covers all economic activities. However, night-time light in an area can reflect the economic activity of the region. This paper focuses on the indirect economic losses caused by the Wenchuan earthquake in 2008 and evaluated the progress of restoration and reconstruction based on night-time light Images. First, the functional relationship between GDP and night-time light parameters was established based on the pre-earthquake data. Next, the indirect loss of the earthquake was evaluated by the night-time light attenuation in the disaster area after the earthquake. Then, the capacity recovery, which is characterized by the brightness recovery process of the light area, was evaluated. Lastly, the process of light expansion in the disaster area was analyzed to evaluate the economic expansion speed and efficiency. | ||||
