Spectrometric handheld light meters that can provide adequate data for evaluation of replacement bulbs for contemporary art objects are now commercially available. This approach was taken to assess potential replacements for the incandescent street lamps in Chris Burden's Urban Light at LACMA, Los Angeles, USA. These meters are also useful tools for monitoring and characterizing museum lighting, which are currently done with illuminance (lux) meters. The new spectral light meters will enable conservators to tailor lighting recommendations for individual artworks, when spectral information from these meters is combined with damage function data on artists’ materials. The latter information can be obtained for some materials by a small modification to the microfade testing procedure, as exemplified by microfading colored samples Henri Matisse created during the design phase for La Gerbe. 相似文献

Childbirth education was an important social movement in the 20th century but has lost its way in recent years. We describe the reasons for the dwindling importance of childbirth education and offer a proposal for reform that will align childbirth education with the needs of today's birthing mothers. Our plan will create "Centers for the Childbearing Year" (CCBYs) and a new model of childbirth educator, which we call the "birth coach." The CCBY is the place for women to go to for information and support related to fertility, pregnancy, childbirth, and newborn care; the birth coach combines the role of childbirth educator, doula, and postpartum caregiver. In creating a fresh model of childbirth education, we not only honor our pioneers but also rediscover the wisdom in community and relationship that childbirth offers us, and we learn in new ways to journey alongside each other to create new possibilities for birthing families. 相似文献
