Title Impact of artificial lighting on capture success in two species of frugivorous bats (chiroptera: phyllostomidae) in an urban locality from the Venezuelan Andes Type Journal Article
Year 2018 Publication Mastozoologia Neotropical Abbreviated Journal
Volume 25 Issue 2 Pages
Keywords Animals
Abstract Artificial light is becoming a major issue for bats because it affects critical activities such as foraging, reproduction, and communication. We assessed the effect of artificial lighting on Artibeus lituratus and Artibeus jamaicensis in a small secondary growth forest patch near a street subjected to unexpected illumination. Bats were captured in the forest patch using a 12-m long mist net. Results indicated a nearly six-fold, significant decrease in capture success after the street lamps were installed. Artificial light from street lamps functions as a “light barrier” that inhibits bats from conducting short and long-distance movements, which might have detrimental consequences for bats and the plants they disperse. RESUMEN. Impacto de la luz artificial en el éxito de captura de dos especies de murciélagos frugívoros (Chiroptera: Phyllostomidae) en una localidad urbana de Los Andes venezolanos. La luz artificial se ha convertido en un problema grave para los murciélagos, porque está afectando actividades críticas que incluyen forrajeo, reproducción y comunicación. Evaluamos el efecto de la luz artificial en los murciélagos frugívoros Artibeus lituratus y Artibeus jamaicensis, en un pequeño parche de bosque secundario, cercano a una calle sujeta a una iluminación artificial inesperada. Capturamos a los murciélagos en el bosque secundario, empleando una red de neblina de 12 m de longitud. Los resultados indican que el éxito de captura disminuyó significativamente casi seis veces después de la instalación de los bombillos. La luz artificial de las lámparas funciona como “barreras u obstáculos de luz” que inhiben a los murciélagos de realizar movimientos de corta y larga distancia, lo cual podría tener consecuencias perjudiciales para los murciélagos y las plantas que ellos dispersan.

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.

Abstract Izvleček

Daljinsko zaznavanje svetlobne onesnaženosti v Sloveniji

V članku so predstavljeni rezultati analize svetlobne onesnaženosti na območju Slovenije v obdobju 2013-2017. Podatki so pridobljeni s satelita Suomi NPP, ki snema površje Zemlje tudi v nočnem kanalu. Prikazani so rezultati svetlobne onesnaženosti po občinah in trendi svetlobne onesnaženosti v omenjenem obdobju. Posebej so izpostavljena območja z zelo visokimi in nizkimi vrednostmi svetlobne onesnaženosti.

Abstract

Remote sensing of light pollution in Slovenia

The study deals with the problem of light pollution in Slovenia in the period 2013-2017. Remotely sensed data were obtained from the Suomi NPP satellite, which is scanning the earth's surface at night. The findings and geospatial trends of light pollution in the mentioned time period are discussed on the national and municipal levels. Some areas with very high and low levels of light pollution were exposed.

Title A Hybrid Tool for Visual Pollution Assessment in Urban Environments Type Journal Article
Year 2019 Publication Sustainability Abbreviated Journal
Volume 11 Issue 8 Pages 1-16
Keywords Planning
Abstract With increasing focus on more nuanced aspects of quality of life, the phenomenon of urban visual pollution has been progressively gaining attention from researchers and policy makers, especially in the developed world. However, the subjectivity and complexity of assessing visual pollution in urban settings remain a challenge, especially given the lack of robust and reliable methods for quantification of visual pollution. This paper presents a novel systematic approach for the development of a robust Visual Pollution Assessment (VPA) tool. A key feature of our methodology is explicit and systematic incorporation of expert and public opinion for listing and ranking Visual Pollution Objects (VPOs). Moreover, our methodology deploys established empirical complex decision-making techniques to address the challenge of subjectivity in weighting the impact of individual VPOs. The resultant VPA tool uses close-ended options to capture the presence and characteristics of various VPOs on a given node. Based on these inputs, it calculates a point based visual pollution scorecard for the observation point. The performance of the VPA tool has been extensively tested and verified at various locations in Pakistan. To the best of our knowledge, this is the first such tool, both in terms of quantitative robustness and broad coverage of VPOs. Our VPA tool will help regulators in assessing and charting visual pollution in a consistent and objective manner. It will also help policy makers by providing an empirical basis for gathering evidence; hence facilitating evidence-based and evidence-driven policy strategies, which are likely to have significant impact, especially in the developing countries.
