Lighting Conditions And Optical Filters Effects On Visual Performance Of Speleologists Exposed To Cave Environments, Carla Costa Lança, Nádia Fernandes, Ana Monteiro, Ana Almeida
International Journal of Speleology
The aim of this study is to evaluate lighting conditions and speleologists’ visual performance using optical filters when exposed to the lighting conditions of cave environments. A cross-sectional study was conducted. Twenty-three speleologists were submitted to an evaluation of visual function in a clinical lab. An examination of visual acuity, contrast sensitivity, stereoacuity and flashlight illuminance levels was also performed in 16 of the 23 speleologists at two caves deprived of natural lightning. Two organic filters (450nm and 550nm) were used to compare visual function with and without filters. The mean age of the speleologists was 40.65 (± 10.93) years. …

Cave Cyanobacteria - thriving in an ‘extreme’ environment with interesting species biodiversity - are supposed to be a potential source of bioactive compounds. Lipid extracts from pure cultures of two recently established Cyanobacteria from Greek caves, Toxopsis calypsus and Phormidium melanochroun, were used for antibacterial screening against human pathogenic bacteria (reference and clinical isolates). Antimicrobial Susceptibility testing for both taxa was carried out using the disc-diffusion (Kirby Bauer) method, while preliminary data applying the standard broth microdilution method for the determination of the Minimal Inhibitory Concentration (MIC) are given only for T. calypsus. Antibacterial activity was demonstrated against the …
Melding Data Collection Methodology With Community Assistance: Benefits To Both Researchers And The Indigenous Groups They Study, Douglas S. London
Melding Data Collection Methodology With Community Assistance: Benefits To Both Researchers And The Indigenous Groups They Study, Douglas S. London
Journal of Ecological Anthropology
I present a description of a model of melding data collection with community aid in the form of health educator training that emerged in the process of research collaboration during 2009-2011 with the Kawymeno Waorani foragers of Amazonian Ecuador. Some guidelines are suggested as to how benefits to both parties might be achieved when collecting data with indigenous populations. In this article I describe some of the advantages and pitfalls of melding data collection and community aid with research when collaborating with vulnerable indigenous groups.
