In the mid-1980s the AUSSAT satellite brought television and radio to remote Australia for the first time. There was concern amongst Aboriginal communities that the imposition of mass media without consultation could result in permanent damage to culture and language. However, over the years, the Warlpiri people have adopted modern communication technology including radio, video making, locally produced television, and more recently on-line services. This paper examines why the Warlpiri have adopted modern communication technology and whether there have been social changes as a result. It also looks at the pioneering media work by the Pitjantjatjara people at Ernabella in the far north of South Australia. 相似文献

Recently there have been newly launched ocean color satellites which target the coastlines at unprecedented scales. Science
education curricula can benefit from the provision of small low-cost spectroradiometers and curriculum supplemental materials
that can be incorporated in a “hands on” teaching approach to explain and demonstrate remote sensing reflectance principles.
A lesson in which a progressive set of spectral measurements of familiar and unfamiliar objects and natural waters acquired
by students using a small fiberoptic probe and spectroradiometer is presented. This lesson has a dual purpose. The first is
to serve as a teaching supplement to high school science curricula while paralleling the National Science Education Standards
(NSES) for NASA ocean color products, as well as other satellite ocean products such as GLI and MERIS. The second is to focus
on the scientific goals of the graduate-school bound undergraduate student by providing a fundamental understanding of the
principles of passive ocean color remote sensing that will perhaps nurture the interest of some students toward research involving
utilization of NASA’s Earth science data products. We intend to have these spectroradiometers readily available for use by
teachers in the Earth sciences through a publicly available technology library. 相似文献
