O SENTIDO DE ALÉTHEIA: PARMÊNIDES E HEIDEGGER

A partir do Poema de Parmênides e da conferência de Heidegger O fim da Filosofia e a tarefa do pensamento, desenvolvemos uma reflexão introdutória acerca do sentido de alétheia para a Filosofia, privilegiando a perspectiva heideggeriana em sua leitura dos diálogos República e Sofista de Platão. Para esse objetivo, mostramos primeiramente em que sentido torna-se possível afirmar haver proximidade entre a “via da alétheia”, de que fala a deusa no Poema de Parmênides, e a “clareira”, de que nos fala Heidegger em sua conferência. Em seguida, procuramos apreender em que sentido a compreensão platônica da alétheia, que se anuncia em fragmentos dos diálogos República e Sofista, se afasta da compreensão heideggeriana mencionada. Finalmente, desenvolvemos por quais razões Heidegger afirma que pensar a essência da metafísica consiste em pensar o seu “impensado”, a saber, a alétheia como clareira

Separating Agent-Functioning and Inter-Agent Coordination by Activated Modules: The DECOMAS Architecture

The embedding of self-organizing inter-agent processes in distributed software applications enables the decentralized coordination system elements, solely based on concerted, localized interactions. The separation and encapsulation of the activities that are conceptually related to the coordination, is a crucial concern for systematic development practices in order to prepare the reuse and systematic integration of coordination processes in software systems. Here, we discuss a programming model that is based on the externalization of processes prescriptions and their embedding in Multi-Agent Systems (MAS). One fundamental design concern for a corresponding execution middleware is the minimal-invasive augmentation of the activities that affect coordination. This design challenge is approached by the activation of agent modules. Modules are converted to software elements that reason about and modify their host agent. We discuss and formalize this extension within the context of a generic coordination architecture and exemplify the proposed programming model with the decentralized management of (web) service infrastructures

Mobility as an Aspect: The AspectM Framework

Software engineers of multi-agent systems (MASs) are faced with the design and implementation of the mobility concern in addition to the agents ’ basic functionalities and other agent-related concerns. As the agents’ complexity increases, the mobility concern cannot be modularized based only on object-oriented abstractions. The mobility concern tends to spread across several system classes and methods, which in turn leads to the production of MASs that are difficult to maintain and reuse. MAS developers, however, have mostly relied on object-oriented frameworks and on object-oriented programming languages, such as Java. This paper presents an aspect-oriented framework, called the AspectM framework, that supports improved modularization of the mobility concern and a flexible integration with multiple mobility platforms. The use of our framework minimizes code replication, and increases the reusability and maintainability of the mobility concern and other agent concerns. 1
