Spectral configurations and interferences in outdoor artificial light at night (Alan) exposure measurements and sleep quality modeling
Outdoor artificial light at night (ALAN) may impact human health through disturbing human circadian rhythms. Laboratory experiments have shown that spectral differences in ALAN may lead to disparities in disturbing human circadian rhythms, but such spectral differences are overlooked in past urban studies due to the difficulties in measuring exposure. This study employed SDGSAT-1 data with multispectral nighttime light and the most advanced mobil…
Does activity context and its temporality matter in the stress-relieving effect of greenspace? Evidence based on individual mobile sensing
Existing discussion on the stress-relieving effects of greenspace tends to overemphasize the dynamics of travel trajectories while overlooking the rich activity contexts and temporality underlying individual behaviors. This oversight may lead to biases and inconsistent findings. Using GPS trajectories of 756 participants in Hong Kong, this study integrates street view data, geographic ecological momentary assessment (GEMA), and activity-travel di…
How mobility-based exposure measures may mitigate the underestimation of the association between green space exposures and health
Recent urban green space research highlighted that mobility-based measures of green space exposure may significantly mitigate a particular type of exposure measurement error (contextual errors) of residence-based measures. In this study, we examined an important manifestation of the contextual errors of residence-based measures: neighborhood effect averaging. We analytically illustrated that the contextual errors of residence-based measures may l…
Dynamic greenspace exposure, individual mental health status and momentary stress level
Assessing momentary stress responses to dynamic real-time greenspace exposure
How Mobility and Temporal Contexts May Affect Environmental Exposure Measurements
Temporal contexts are essential for the derivation of causally relevant environmental exposure in environmental and public health studies. We argue that the proper temporal contexts need further emphasis in the mobility-oriented research paradigm and articulate this issue using a study in Hong Kong. We use people’s exposure to outdoor artificial light at night (ALAN) and green space as two essential examples. We recruited 208 participants from tw…
