This research works towards the integration of cultural factors in global information systems like the Web or digital libraries to enhance global access to information and services. In this context, we study cultural differences in categorization and classification by means of card sorting experiments in combination with observations and interviews. An initial analysis of data collected in Paki...

WHEN GREGORY BATESON was conducting fieldwork in New Guinea, his friends among the native Iatmul could not understand why he had to work so hard to learn their language: “But our language is easy to understand” they told him, “we just talk.”1 I wonder how Romans would react to an American studying their gestures from a distance of two millennia. A predictable response would be that their body l...

In this paper, a discrete-time multi-agent system is presented which is formulated in terms of the delta operator. The proposed multi-agent system can unify discrete-time and continuous-time multi-agent systems. In a multi-agent network, in practice, the communication among agents is acted upon by various factors. The communication network among faulty agents may cause link failures, which is m...

Abstract: This paper studies consensus and H∞ consensus problems for heterogeneous multi-agent systems composed of first-order and second-order integrator agents. We first rewrite the multi-agent systems into the corresponding reduced-order systems based on the graph theory and the reduced-order transformation. Then, the linear matrix inequality approach is used to consider the consensus of het...

Results: From 1991 to 2000, 62,839 EP were reported in California. Mean EP rate was 11.2/ 1000, decreased from 15/1000 to 9.3/1000, and varied significantly by race/ethnicity and age. EP rates were highest among African Americans (25/1000) and lowest among Hispanics (7.7/1000); African Americans had higher odds of having EP relative to nonHispanic Whites (odds ratio [OR] 2.14, 95% confidence in...

Cultural documentation, i.e. the recording and management of a body of knowledge about ensembles of cultural goods, presents special requirements of a computer-based information system, not met by ordinary documentation systems and cultural information bases. The CLIO system aims at covering these needs, while it can also cooperate with an administrative documentation system. Information is org...
