Materiais cerâmicos do povoado calcolítico do Monte da Tumba (Torrão) : análises macro e microscópicas

Os autores procedem à análise das pastas cerâmicas de 24 amostras de número de recipientes, do povoado calcolítico do Monte da Tumba, recorrendo ao microscópio petrográfico. Esta metodologia revelou-se muito eficaz e permitiu atingir conclusões importantes nos domínios da tecnologia e da análise do site-catchement. De sublinhar a constatação de que as dimensões dos elementos não plásticos das pastas argilosas não parecem relacionar-se com as dimensões nem com a espessura das paredes dos recipientes, mas com o grau de resistência e porosidade pretendidos. Registe-se igualmente que as produções cerâmicas utilizaram matérias-primas locais, num raio de distância mínimo de 750m a partir do povoado.

A bot spooler architecture to integrate virtual worlds with e-learning management systems for corporate training

Joining efforts of academic and corporate teams, we developed an integration architecture - MULTIS - that enables corporate e-learning managers to use a Learning Management System (LMS) for management of educational activities in virtual worlds. This architecture was then implemented for the Formare LMS. In this paper we present this architecture and concretizations of its implementation for the Second Life Grid/OpenSimulator virtual world platforms. Current systems are focused on activities managed by individual trainers, rather than groups of trainers and large numbers of trainees: they focus on providing the LMS with information about educational activities taking place in a virtual world and/or being able to access within the virtual world some of the information stored in the LMS, and disregard the streamlining of activity setup and data collection in multi-trainer contexts, among other administrative issues. This architecture aims to overcome the limitations of existing systems for organizational management of corporate e-learning activities.
