Collaborative Efforts

This chapter highlights selective key issues and assesses the current situation of digital library development in the Asia Pacific under the broad categories of design architecture and systems, implementation issues and challenges, use and impact, and users and usability. Emphasis on cross-cultural and cross-lingual research would especially be beneficial to address the diversity and richness of the heritage, cultures and languages of this region. Nonetheless, a fundamental digital divide problem poses the greatest challenge as almost 70% of the population of the countries of Asia Pacific has little or no connectivity to the digital world. Concerted international collaborative efforts are much needed, not only to push ahead with the various aspects of the digital library research agenda and realize the global digital library vision of the future, but to derive novel solutions to eliminate or close the gap of digital divide across various parts of the world.

Key Issues

In electron energy loss spectroscopy (EELS), the near-edge region of a core-loss edge contains information on high-order atomic correlations. These correlations give details of the 3-D atomic structure which can be elucidated using multiple-scattering (MS) theory. MS calculations use real space clusters making them ideal for use in low-symmetry systems such as defects and interfaces. When coupled with the atomic spatial resolution capabilities of the scanning transmission electron microscope (STEM), there therefore exists the ability to obtain 3-D structural information from individual atomic scale structures. For ceramic materials where the structure-property relationships are dominated by defects and interfaces, this methodology can provide unique information on key issues such as like-ion repulsion and the presence of vacancies, impurities and structural distortion.An example of the use of MS-theory is shown in fig 1, where an experimental oxygen K-edge from SrTiO3 is compared to full MS-calculations for successive shells (a shell consists of neighboring atoms, so that 1 shell includes only nearest neighbors, 2 shells includes first and second-nearest neighbors, and so on).
