  Title The effects of light at night and/or melatonin on hormones, metabo- lites, appetite control, vascular function, and behavioural responses. Type Journal Article
  Year 2017 Publication University of Surrey Abbreviated Journal  
  Volume Issue Pages  
  Keywords Human Health  
  Abstract Light at night (LAN) is a major factor in disruption of SCN function, including melatonin suppression. Melatonin has been linked to a variety of biological processes such as lipid and glucose metabolism, vascular parameters, appetite, and behaviour. However, few human studies have investigated the effect of LAN and suppressed melatonin prior to and after an evening meal. The current thesis aims to investigate the impact of light at night and/or mela- tonin on hormones, metabolites, appetite, vascular function, and behaviour prior to and after an evening test meal in healthy participants. The first study investigated the effect of dim or bright light conditions on hor- mones, metabolites, appetite, vascular function and behavioural responses. Glucose tolerance and insulin sensitivity were reduced, lipid profiles altered and salivary melatonin suppressed under bright light compared to dim light conditions. Subjec- tive mood was improved and appetite scores increased in bright light. No differences were seen in vascular parameters. Although clear differences were apparent it could not be determined whether the effects were due to the light at night, the absence of melatonin or a combination of the two. The second study involved three conditions with the administration of exogenous melatonin 90 mins before the evening test meal under bright and dim light conditions compared to bright light alone with the consequent melatonin suppression. Glucose tolerance and insulin sensitivity were reduced and lipid profile altered in bright light when melatonin was suppressed compared to the two conditions with exogenous melatonin. Mood was improved and appetite increased with lower leptin levels and elevated wrist temperature with bright light and suppressed melatonin. Statistical analysis showed that the major effects were due to melatonin. These studies demonstrate a possible role for melatonin in glucose tolerance, insulin sensitivity and lipid metabolism when eating late at night which may have implications for shift-workers.

  Title Hazards, Causes and Legal Governance Measures of China's Urban Light Pollution Type Journal Article
  Year 2017 Publication Nature Environment and Pollution Technology Abbreviated Journal  
  Volume 16 Issue 3 Pages 975-980  
  Keywords Regulation  
  Abstract Urban light pollution, which poses a threat to people’s production, life, and physical and mental health, is becoming increasingly serious and gradually forms a new type of environmental pollution. In order to further analyse the hazards and causes of China’s urban light pollution and explore its legal governance measures, this study reviews foreign literature on hazards and causes of urban light pollution, summarizes the types and causes of the pollution in China, and provides specific control measures from the perspective of legal governance. Research results in the country and abroad show that light pollution is caused by development, which has a serious negative impact on the normal life of urban residents. The hazards of urban light pollution are manifested in four aspects, such as damaging human health, affecting the natural ecological environment, affecting normal operation of urban traffic, and causing serious waste of energy. Urban light pollution is caused by the lack of systematized urban building light source design work, excessive use of electronic products with the development of science and technology, weak public awareness of environmental protection, and the delay of laws and regulations. Some legal measures to control light pollution are presented as follows: Perfecting the administrative system and environmental supervision system in legislation, innovating the legislation system of light pollution prevention, formulating strict civil liability for light pollution, and further formulating a single law on light pollution control. The results of this study have important reference value for taking measures predictably to avoid the occurrence of light pollution during urban construction design, for the macro-control of urban planning and management departments, and for promoting the concept of urban environmental protection and energy conservation and sustainable urban development.

  Title Illuminance required to detect a pavement obstacle of critical size Type Journal Article
  Year 2018 Publication Lighting Research & Technology Abbreviated Journal  
  Volume 50 Issue Pages 390-404  
  Keywords Vision; Lighting  
  Abstract This paper investigates the illuminance needed to detect trip hazards for pedestrians walking after dark. In previous work, it was assumed that the critical obstacle height is 25 mm: further review of accident data and foot clearance data suggests instead that 10 mm is the critical height. Eye tracking records suggest a tendency for obstacles to be detected approximately 3.4 m ahead. Interpretation of obstacle detection data suggests horizontal photopic illuminances of up to 0.9 lux are required for peripheral detection of a 10 mm obstacle 3.4 m ahead, according to the scotopic/photopic ratio of the lighting and the age of the observer.

  Title Road lighting and accidents: Why lighting is not the only answer Type Journal Article
  Year 2017 Publication Lighting Journal Abbreviated Journal  
  Volume 82 Issue 5 Pages 22-26  
  Keywords Lighting; Public Safety  
  Abstract Tony Price and Steve Fotios point out that while road lighting can be a significant counter measure to accidents, and that higher levels might help, the presence of road lighting does not guarantee all accidents will be avoided.

  Title The transition between lit and unlit sections of road and detection of driving hazards after dark Type Journal Article
  Year 2017 Publication Lighting Research & Technology Abbreviated Journal  
  Volume 51 Issue 2 Pages 243-261  
  Keywords Vision; Public Safety; Lighting; Planning  
  Abstract An experiment to investigate peripheral detection performance during a driver’s transition between lit and unlit sections of road was undertaken. The results suggest that when a driver moves from a lit to an unlit section of road their detection performance decreases almost immediately to that expected for the conditions of the unlit section and that there is no significant change in the subsequent 20-minute period. Tests were conducted at three luminances (0.1, 1.0 and 2.0 cd/m2): while an increase from 0.1 to 1.0 cd/m2 improved detection, a further increase to 2.0 cd/m2 did not. Lighting of two S/P ratios (0.65, 1.40) was examined at 1.0 cd/m2: this did not suggest an effect on detection performance. Taken together, these results suggest that, in the current context, visual performance reached a plateau at 1.0 cd/m2.
