Title The Twilight Envelope: A User-Centered Approach to Describing Roadway Illumination at Night Type Journal Article
Year 2001 Publication Human Factors: The Journal of the Human Factors and Ergonomics Society Abbreviated Journal
Volume 43 Issue 4 Pages 620-630
Keywords Society
Abstract Visual recognition functions, such as acuity and contrast sensitivity, deteriorate rapidly over the declining luminances found during civil twilight. Thus civil twilight, a critical part of the transition between daylight and darkness, represents lighting conditions that may be useful to describe artificial illumination. Automotive headlamps project a three-dimensional beam that ranges from illumination levels comparable to daylight at the vehicle to the dark limit of civil twilight (3.3 1x) at some distance ahead. This twilight envelope is characterized as a distance beyond which foveal visual functions are severely impaired, and thus it provides a general, functional description of the useful extent of the headlamp beam. This user-centered approach to describing illumination is useful for characterizing visibility when driving at night or in other artificially lit environments. This paper discusses the twilight envelope approach and its application to intervehicle variations in headlamp systems. Actual or potential applications of this research include user-centered description of artificial illumination and driver/pedestrian safety education.

Title Students’ Opinions on the Light Pollution Application Type Journal Article
Year 2015 Publication International Electronic Journal of Elementary Education Abbreviated Journal IEJEE
Volume 8 Issue 1 Pages 55-68
Keywords Society; awareness; perception; education; child development; light pollution
Abstract The purpose of this study is to determine the impact of computer-animated concept cartoons and outdoor science activities on creating awareness among seventh graders about light pollution. It also aims to identify the views of the students on the activities that were carried out. This study used one group pre-test/post-test experimental design model with 30 seventh graders. The data in the study were collected via open-ended questions on light pollution and semi-structured interview questions. The open-ended questions on light pollution were administered as a pre-test and a post-test. After the post-test was administered, semi-structured interviews were conducted with seven students. The data collected from the open-ended questions and semi-structured interviews were qualitatively analysed and quotes from the students’ statements were included. Looking at the answers of the students to questions on light pollution, it was understood that the activities that were carried out were effective. Furthermore, all of the students that were interviewed made positive statements about the activities that were carried out.

Title Dark Nights, Bright Lights: Night, Darkness, and Illumination in Literature Type Book Whole
Year 2015 Publication Abbreviated Journal
Volume Issue Pages
Keywords Society; literature; art
Abstract Light and darkness shape our perception of the world. This is true in a literal sense, but also metaphorically: in theology, philosophy, literature and the arts the light of day signifies life, safety, knowledge and all that is good, while the darkness of the night suggests death, danger, ignorance and evil.

A closer inspection, however, reveals that things are not quite so clear cut and that light and darkness cannot be understood as simple binary opposites. On a biological level, for example, daylight and darkness are inseparable factors in the calibration of our circadian rhythms, and a lack of periodical darkness appears to be as contrary to health as a lack of exposure to sunlight. On a cultural level, too, night and darkness are far from being universally condemnable: in fiction, drama and poetry the darkness of the night allows not only nightmares but also dreams, it allows criminals to ply their trade and allows lovers to meet, it allows the pursuit of pleasure as well as deep thought, it allows metamorphoses, transformations and transgressions unthinkable in the light of day. But night is not merely darkness. The night gains significance as an alternative space, as an ‘other of the day’, only when it is at least partially illuminated.

The volume examines the interconnection of night, darkness and nocturnal illumination across a broad range of literary texts. The individual essays examine historically specific light conditions in literature, tracing the symbolic and metaphoric content of darkness and illumination and the attitudes towards them.
