In this article, I defend the thesis that selfishness and altruism can be intrapersonal. In doing so, I argue that the notions of intrapersonal altruism and selfishness usefully pick out behavioural patterns and have predictive value. I also argue that my thesis helps enrich our understanding of the prudential, and can subsume some interesting work in economic and psychological theory. 'Why bot...

An itinerary scripting language provides a tool to accelerate the development of mobile agent applications. The main purpose of this paper is to discuss research challenges of itinerant mobile agents (ITAG) and describe the migration of ITAG to JADE, the popular FIPA-compliant agent platform. The migration process was based on two major steps: the migration of agent communications and agent tas...

Recent experiments have shown that people iconically modulate their prosody corresponding with the meaning of their utterance (e.g., Shintel et al., 2006). This article reports findings from a story reading task that expands the investigation of iconic prosody to abstract meanings in addition to concrete ones. Participants read stories that contrasted along concrete and abstract semantic dimens...

Grazing frequency, grazing intensity, plant health, and grazer abundances were examined under two different fertilization regimes and compared to unfertilized areas of Juncus roemerianus (black needlerush) marsh. These measurements were taken in three separate sites: two low elevation sites and one high elevation site. Fertilizer was added over one grazing season (April–August) with measurement...

We advocate the event-based communication genre for mobile agent communities, which is useful for exchanging and disseminating large volumes of small lightweight messages. We propose that the publish-subscribe model complements the proprietary or standard agent communication languages. We describe how we implemented the event notification mechanism for mobile agents, and analyse experiments tha...

There is a need for agent oriented software engineering (AOSE) methodologies that support the conceptual modelling of mobile agent systems. In this paper, we present m-GAIA, our extension to the GAIA methodology for modelling mobile agent systems. m-GAIA incorporates explicit constructs to perform the analysis and design of multiagent systems which include mobile agents. We also present our exp...
