Turkish D-light : accentuating heritage values with daylight
Historic buildings have their own cultural identity, which is often related to their aesthetic qualities such as period
characteristics (geometry, size, colour, form and shape), materials and construction. Daylight is one of the primary
elements contributing to the distinctiveness of the visual environment of many historic buildings, but is rarely
considered as one of the components that shape the character of a building when adaptive preservation schemes of
historical buildings are planned. Many historic buildings were originally designed to accommodate activities different to
their new use and preserving the quality of daylight that originally contributed to their visual identity is a challenging
task. Maintaining the ‘day-lit appearance’ of a building can be particularly problematic if the building is to be used as a
museum or a gallery owing to the artefacts’ conservation requirements. This work investigated the opportunities of
maintaining the original ambient conditions of renovated historical buildings while meeting the required daylight levels
of the proposed new use. The study utilised an annual daylight simulation method and hourly weather data to preserve
daylight conditions in renovated historic buildings. The model was piloted in a Turkish bathhouse situated in Bursa,
Turkey, that is currently under renovation. The simulation model produces 4483 hourly values of daylight illuminance
for a period of a whole year using the computer program Radiance. It is concluded that daylight characteristics should
be taken into account when developing a renovation scheme. With increasing pressure on valuing historic buildings in
many parts of the world, the work reported here should be beneficial to those concerned with the conservation and
adaptive reuse of historic buildings. The study findings could also be useful to those interested in predicting potential
energy savings by combining daylighting and electric lighting in historic buildings

Irreversibility, Uncertainty, and Learning: Portraits of Adaptation to Long-Term Climate Change
Comparison of Postfire Seeding Practices for Wyoming Big Sagebrush
Wildfires in the Great Basin have resulted in widespread loss of Wyoming big sagebrush (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young), an ecologically important shrub that has proven difficult to establish from seed. We sought to identify optimal seeding practices for Wyoming big sagebrush in the context of postfire seeding operations involving rangeland drills. In an experiment replicated at three burned sites in the northern Great Basin, we compared Wyoming big sagebrush establishment across treatments differing by seed delivery technique, timing, and rate of seed application. A seed mix containing bunchgrasses was drill-seeded in alternate rows using one of two drill-types (conventional or minimum-till), and a mix containing sagebrush was either delivered by drill to the soil surface in remaining rows or broadcast by hand (simulating aerial seeding) following drilling in fall or winter. Drill-delivery of sagebrush seed was accompanied by drag chains (conventional drill) or imprinter wheels (minimum-till drill) to improve seed-soil contact and was carried out at multiple seeding rates (ca. 50,250, and 500 pure live seed m-2). During 2 yr following seeding, sagebrush establishment was lower at two sites (yr 1: ≤ 1.2 plants m-2; yr 2: ≤ 0.8 plants m-2) compared with a third site (yr 1: ≤ 4.1 plants m-2; yr 2: ≤ 2.0 plants m-2) where treatment differences were more pronounced and significant. Wherever density differed between treatments, it was consistently higher in certain treatment levels (minimum-till > conventional drill, drill-delivery > broadcast-delivery, fall broadcast > winter broadcast, and higher rates > lower rates). Densities declined between years at two sites, but we did not find evidence that declines were due to densitydependent mortality. Results indicate that seeding success can likely be enhanced by using a minimum-till imprinter seeding method and using seeding rates higher than typical postfire seeding recommendations for Wyoming big sagebrush. © Published by Elsevier Inc. on behalf of The Society for Range Management.The Rangeland Ecology & Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Religion and the Japanese American Incarceration
Abundant scholarship analyzes the United States\u27 incarceration of Japanese Americans during World War II, but the subject of religion in the camps and religious responses to the incarceration has been long overlooked. The government promised freedom of religion in the camps while encouraging Japanese Americans to consolidate worship into one Buddhist, one Catholic, and one Protestant church in each incarceration center. Incarcerees found strength through fellowship and religious faith. Outside of the camps, progressive Christians tried to alleviate the harms caused by the injustice and increase tolerance around the country. The field offers examples of early race relations work within American Protestantism and introduces the ways in which the government prioritized and attempted to enforce freedom of religion within a fabricated and restricted wartime environment. Further examination of these events will complement studies of 20th century liberal Christianity, American Buddhism, religious liberty and the state, the early civil rights movement, religion and World War II, and Asian American theology
