Underground mine Refuge Chamber Expectations Training: Program development and evaluation

Refuge chambers are new devices for underground coal mines that provide approximately 96 h of breathable air, water, food, and supplies in the event of an emergency where miners are unable to escape. Researchers at the National Institute for Occupational Safety and Health (NIOSH) developed a training program to prepare miners for what to expect psychologically and physiologically inside of a refuge chamber. The field tests of this training revealed that it was received very positively by miners and helped impart realistic views about the physical discomforts and psychological stresses of being inside a refuge chamber.     

Green tenants: practicing a sustainability ethics for the rental housing sector

The shift towards social, government and corporate ethics which value environmental sustainability has also embraced householders in a plethora of educational guides, policies, regulations and consumer information about green home improvements, purchasing choices and household practices. In this paper, we make the claim that the rental housing sector, and in particular the private rental sector, has yet to participate, structurally, culturally and materially, in this shift to an ethics of sustainability. We argue, however, that even on such otherwise arid ground, an alternative ethic is developing, a sustainability ethic practiced by green tenants whose activities inside and outside their homes go beyond the considerable material constraints of their dwellings and incomes, and beyond the purely transactional utility of the rental contract. These activities, relational, interconnected and resilient, offer both glimpses of a greening rental housing sector, and a clearer picture of the areas where work remains to be done. Based on a research study, we conducted of the rental sector in regional Australia, and in particular of the everyday sustainability practices of tenants, we suggest that these activities are a practice-based form of care for the world, in many ways similar to Maria Puig de la Bellacasa's practice-based, human-decentred ethics which she suggests is exemplified in the permaculture movement. The stories of the tenants we interviewed for our study also point the way to other changes which are needed to enable a practice-based sustainability ethic to flourish across the rental housing sector as a whole.     

Interrelationship of age and diet in Romania’s oldest human burial

In 1968, excavations in the Climente II cave in the Iron Gates gorge of the River Danube in southwest Romania unearthed the skeleton of an adult male. The burial was assumed to be of Late Pleistocene age because of the presence of Late Upper Palaeolithic (LUP) artefacts in the cave. However, there was no strong supporting stratigraphic evidence, and the body position is reminiscent of Early Neolithic burial practice in the region. Here, we report the results of radiocarbon and stable isotope analyses of the Climente II skeleton, which show that the skeleton dates to the Bølling–Allerød Interstadial ~14,500 cal BP. This is several millennia older than any previously dated human remains from the Iron Gates region and confirms its status as the oldest known burial from Romania. The stable isotope results indicate a diet with an emphasis on aquatic resources, contrary to the commonly held view that the LUP inhabitants of the Iron Gates subsisted mainly by hunting large land mammals.     

Fuel Reduction Management Practices in Riparian Areas of the Western USA

Two decades of uncharacteristically severe wildfires have caused government and private land managers to actively reduce hazardous fuels to lessen wildfire severity in western forests, including riparian areas. Because riparian fuel treatments are a fairly new management strategy, we set out to document their frequency and extent on federal lands in the western U.S. Seventy-four USDA Forest Service Fire Management Officers (FMOs) in 11 states were interviewed to collect information on the number and characteristics of riparian fuel reduction treatments in their management district. Just under half of the FMOs surveyed (43%) indicated that they were conducting fuel reduction treatments in riparian areas. The primary management objective listed for these projects was either fuel reduction (81%) or ecological restoration and habitat improvement (41%), though multiple management goals were common (56%). Most projects were of small extent (93% < 300 acres), occurred in the wildland-urban interface (75%), and were conducted in ways to minimize negative impacts on species and habitats. The results of this survey suggest that managers are proceeding cautiously with treatments. To facilitate project planning and implementation, managers recommended early coordination with resource specialists, such as hydrologists and fish and wildlife biologists. Well-designed monitoring of the consequences of riparian fuel treatments on fuel loads, fire risk, and ecological effects is needed to provide a scientifically-defensible basis for the continued and growing implementation of these treatments.
