Our approach allows resource providers to delegate some of the authority for maintaining fine-grained access control policies to communities, while still maintaining ultimate control over

in distributing the policy to the domains, but also because of the fact that those domains may each have different capabilities for enforcing the policy. The Community Authorization Service (CAS) solves this problem by allowing resource providers to delegate some policy authority to the VO while maintaining

to shared resource, authorization is essential in VO. Authorization in VO is challenging because of the dynamic and distributed nature of VO. A community authorization service (CAS) was proposed recently to meet the Grid challenges and to enforce fine-grained access control policies in the VO. However

This is a field report of a three-week experience in Japan, centered on art education in their cultural and social contexts. Beginning with this overarching focus, the themes and patterns that structure this report were emergent, rising from the experience. Those supporting themes are: being in Japan and in Mino city (setting a context); the culture of handmade Washi paper; the qualities of the Washi paper festival; craft as a way of teaching, being and learning; children and their art at school and through the festival, and the importance of ritual. This report is written in a personal narrative style as suggested in contemporary feminist and transactive ethnographic literature. Key Words：cross-cultural art education, feminist, transactive ethnography, Japanese art education Report from Japan: Art,

be technically challenging because of the need to achieve various qualities of service when running on top of different native platforms. We present an Open Grid Services Architecture that addresses these challenges. Building on concepts and technologies from the Grid and Web services communities

Grid technologies enable large-scale sharing of resources within formal or informal consortia of individuals and/or institutions: what are sometimes called virtual organizations. In these settings, the discovery, characterization, and monitoring of resources, services, and computations

the Community Authorization Service (CAS) provided by the Globus Toolkit to support the RBAC within the OGSA-DAI framework. The CAS grants the membership on VO roles to users. The resource providers then need to maintain only the mapping information from VO roles to local database roles in the role-map files
