Title Shot in the Dark: Nocturnal Philosophy and Night Photography Type Book Chapter
Year 2018 Publication Critical Distance in Documentary Media Abbreviated Journal
Volume Issue Pages 45-67
Keywords Society; Art
Abstract This chapter examines the neglected practice of night photography, and how it critically addresses the environmental, sociohistorical, and urban issues in recent series by Christina Seely, Bruno Lessard, Michel Huneault, and Jeanine Michna-Bales. Drawing on Jacques Derrida, Emmanuel Levinas, and the emerging field of night studies to create a nocturnal philosophy—a dark photology—with which to frame the multifaceted issues at the heart of the series, the author examines the value that these photographic artists place upon night to document light pollution around the world, ongoing urban transformations in China, an environmental catastrophe and its aftermath in Québec, and the landscape of the Underground Railroad in the United States. These four series demonstrate how night photography offers a unique critical perspective on some of the most pressing problems of our age, and how these artists distance themselves from the predominantly diurnal register of documentary media.

Title Differential Drift in Menarcheal Age in Blind and Sighted Girls Type Journal Article
Year 2018 Publication Gynaecology and Perinatology Abbreviated Journal
Volume 2 Issue 4 Pages 333-339
Keywords Human Health
Abstract Our survey data show that menarcheal age, both in sighted and blind girls has drifted towards younger years compared to 50 years back, however, in sighted girls it has gone further down compared to blind girls. In this paper we have explained the reasons, why it is so? For the comparison sake we were very careful to select sighted and blind girls from the same geographical region, socio-economical and education status and food habits. Taking into consideration, our earlier hypothesis, “blind women and breast cancer”, here also we propose that only the photo regulatory system for hormonal axis is responsible for differential lowering of Menarcheal age in sighted and blind girls, since all other regulatory factors are same in both the groups.

Title 0038 Sleeping with Low Levels of Artificial Light at Night Increases Systemic Inflammation in Humans Type Journal Article
Year 2019 Publication Sleep Abbreviated Journal
Volume 42 Issue Supplement_1 Pages A15-A16
Keywords Human Health
Abstract Introduction

Artificial light at night (ALAN) has become a ubiquitous part of our society. Animal studies have shown that ALAN exposure promotes a depressive-like mood and increases peripheral inflammation likely due to circadian disruption. We hypothesized that sleeping with ALAN will increase systemic inflammation in humans.

Methods

We enrolled 64 subjects [32 with obstructive sleep apnea (OSA) adherent to treatment and 32 without sleep disorders] in a randomized, crossover study to determine the effects of sleeping with ALAN (40 lux) or the usual dark condition (control) for 7 nights at home. Sleeping with ALAN was confirmed by an actigraph with an ambient light sensor. Outcome measurements were done at baseline and after sleeping in each condition. The primary outcome was changes in the high-sensitivity C-reactive protein (hsCRP) levels. Secondary outcomes include scores on the Pittsburgh Sleep Quality Index (PSQI), Center for Epidemiologic Studies Depression Scale (CES-D), Functional Outcomes of Sleep Questionnaire-10 (FOSQ-10), and Epworth Sleepiness Scale (ESS); Psychomotor Vigilance Testing (PVT); actigraphic sleep measures; and homeostatic model assessment of insulin resistance (HOMA-IR). A random effects linear regression model was used to assess differences adjusting for schedule, visit, and baseline levels. Post-hoc analyses combined results from OSA and non-OSA subjects.

Results

Fifty-eight (30 OSA and 28 non-OSA) subjects, aged 38.4±14.9 years, 33 of whom are male completed the protocol. A log transformation was used so the difference in hsCRP was expressed as a mean ratio. In the combined analysis, the mean hsCRP was 39% higher with ALAN than control (mean ratio=1.39; 95% CI: 1.08-1.80; p=0.012). The effects of ALAN for OSA and non-OSA subjects were not different. ALAN increased the CES-D score by 1.81 (p=0.017) and ESS score by 0.62 (p=0.071) points, and decreased the FOSQ-10 score by 0.36 (p=0.038) points while the PSQI score was unchanged (p=0.860). There were no significant differences in the PVT values, actigraphic sleep measures, or HOMA-IR.

Conclusion

Sleeping with ALAN for seven days significantly increased hsCRP levels and modestly increased depression scores in humans.

Title Sleep Disturbance among Pregnant Women: The Influence of Environmental and Contextual Factors Type Journal Article
Year 2019 Publication Sleep Abbreviated Journal
Volume 42 Issue Supplement_1 Pages A270-A271
Keywords Human Health
Abstract Introduction

Disrupted sleep during pregnancy affects nearly 85% of women. This can contribute to psychological distress and antenatal depression. The aims of the current project were to test whether (a) poorer subjective sleep quality contributed to greater depression and anxiety symptoms, and (b) contextual factors predicted clinically significant sleep disturbance after adjusting for socioeconomic status (SES).

Methods

In a mixed-methods study, 418 pregnant women (age: M=32.4 years; gestation: M=28.4 weeks, SD=8.4 weeks; 58% Black) completed the Pittsburgh Sleep Quality Index (PSQI), measures of pregnancy-related physiological factors, and provided details about their sleep environment. They also rated perinatal depression, anxiety, and SES (Hollingshead and MacArthur Ladder). Sixty-two women completed these measures again later in pregnancy (gestation M = 34.2 weeks). A subset of seven women underwent actigraphy (9-nights) during their third trimester. Logistic regressions adjusted for age, BMI, race, sleep disordered breathing, and gestational week.

Results

Subjective sleep quality was significantly poorer among Black women and those with higher BMI. Physiological factors (i.e., restless leg syndrome, nocturnal urination, and acid reflux) explained subjective sleep disturbance after accounting for gestational week (ps<.01). Among women with history of psychopathology (n=221), sleep disturbance was significantly related to anxiety and depression symptoms (ps<.01), with greater sleep disturbance (PSQI score >5) predicting clinically significant antenatal depression (B = .38, p<.05). However, those who rated their social standing as higher reported lower sleep disturbance throughout pregnancy, even after adjusting for mood and anxiety (B= .86, SE =.41; p<.05). There was a dose-response positive association between sleep disturbance and depression severity among Black women only (B = .89; p<.05). Among lower SES Black women, environmental factors (greater ambient noise and light pollution) partially mediated this effect (B= .45, SE =.17; p<.01).

Conclusion

Sociocontextual factors may explain sleep disturbance severity among low-income pregnant Black women, above and beyond traditional metrics of SES. Higher subjective SES may be protective against sleep disturbance and psychiatric distress. Assessments of sleep during pregnancy should account for physiological considerations and environmental disruptions, alongside mood and anxiety.

Title Why do nocturnal grasshoppers and katydids “salute” to flash photography? Type Journal Article
Year 2019 Publication Entomological Science Abbreviated Journal Entomological Science
Volume 22 Issue 2 Pages 216-219
Keywords Animals; Insects; grasshoppers; katydids; orthoptera
Abstract Nocturnal animals can be sensitive to powerful light from the environment. Anthropogenically induced perturbation to natural light regimes, including ecological light pollution and flash photography, can have wide‐reaching implications on the ecology and behavior. Ecological ramifications of strong lights were traditionally focused on vertebrates although there is now more focus on invertebrates. Nonetheless, there are still unanswered questions on visual ecology and evolution, particularly on individual‐level effects and of tropical species. Specifically, how invertebrate individuals react to strong light is generally undocumented. Based on opportunistic surveys around Southeast Asia, orthopterans, spotted using concentrated torchlight and exposed to sudden strong light intensity during flash macrophotography, were observed to screen themselves by positioning their foreleg over the dorsum of the compound eye. This resembled the orthopteran “saluting” to the camera. These observations provided empirical evidence of how high intensity light can unsettle orthopterans and other insects and further ecological and evolutionary hypotheses and questions can be raised to understand the effect of light pollution.
