The Messenger paradigm and its implications on distributed systems

Most distributed systems are built on top of a message exchange infrastructure. Processes coordinate their execution by exchanging messages which are interpreted according to a pre-established set of protocols. We present in this paper a novel way of communicating which does not require the preconfiguration of protocol entities. The host initiating the communication has the ability…

Distributed Semaphore In A Messenger Environment

The messenger paradigm advocates the exchange of programs called messengers between communicating hosts instead of messages. Each host contains a messenger execution environment called messenger platform. Messengers are expressed in a language understood by all the platforms. A distributed messenger environment is a collection of messenger platforms linked through an unreliable…

SANDS1.5/COOPN1.5 An Overview of the Language and its Supporting Tools

In this document we give an overview of the CO-OPN/1.5 (Concurrent Object-Oriented Petri Nets) specification language and describe the features of each tool provided in the SANDS/1.5 (Structured Algebraic Net Development System) development environment. The CO-OPN/1.5 language is a specification language devised to support the development of large concurrent systems. The underlying…

Mathematical Formalization of the Messenger Paradigm

This technical report presents the syntax and semantics, in terms of transition system, of the messenger paradigm as it has been presented in [8]. Messengers are mobile agents able to collaborate and to coordinate their work, but are not considered as intelligent agents. More precisely, messengers are mobile codes exchanged between messenger platforms. Arriving messengers are…

A Distributed Micro–Kernel for Communications Messengers

Mobile software agents require a distributed execution environment in which they can command the use of many resources like memory, CPU time and bandwidth. While current research seems to concentrate on roaming agents at the application level and tries to define suitable high–level environments, we think that such an execution environment must be rooted at a very low-level. We argue…

Towards Hypermedia Electronic Publishing

The most important problem that decision makers face in today's ever increasing information flux is how to find efficiently and fast the useful information. Hypermedia Electronic Publishing systems, supporting active information distribution and offering hypertext browsing facilities, provide a promising solution to this problem. Nevertheless several issues, like value added…

From Comparative Public Policy to Political Economy: Putting Political Institutions in their Place and Taking Interests Seriously

The historical institutionalist tradition in comparative politics commonly assigns analytical primacy to political institutions. Whereas this polity-centeredness may be quite justifiable for purposes of comparative public policy, students of comparative political economy should pay systematic attention not only to economic institutions but also to a range of economic-structural…

Multiculturalisme et démocratie : quelques implications pour la théorie de la citoyenneté

La dynamique sociale et politique du multiculturalisme constitue un défi pour la conception libérale traditionnelle de la citoyenneté. L'article part du constat que ce phénomène se caractérise essentiellement par une dispersion des identités et par la coexistence d'une multiplicité d'allégeances culturelles. Sa spécificité tient au fait qu'un nombre croissant d…

Are Grouped Data Robustly Fitted?

In this paper we compute the IF of a general class of estimators for grouped data, namely the class of MPE. We find that this IF can be large although it is bounded. Therefore, we propose a more general class of estimators, the MGP-estimators, which include the class of estimators based on the power divergence statistic and permits to define robust estimators. By analogy with Hampel…

Choosing between two parametric models robustly

In this paper we propose a robust version of Cox-type test statistics for the choice between two non-nested hypotheses. We first show that the influence of small amounts of contamination in the data on the test decision can be very large. Secondly we build a robust test statistic by using the results on robust parametric tests available in the literature and show that the level of…

Income inequality decomposition by income source and the breakdown of inequality differences between two population subgroups

This study analyses first the impact of various income sources on overall income inequality in Switzerland in 1980, on the basis of the Income and Wealth Survey which was conducted during that year. The specific effect of each of these income sources is analyzed separately for male- and female-headed households and an attempt is made to also determine their role in explaining the…

Le clivage entre Suisses romands et Suisses alémaniques par rapport à l'intégration européenne

En 1992, lors d'un référendum sur l'Espace économique européen, un important clivage est apparu entre Suisses romands et Suisses alémaniques. Cet article recense les interprétations données à ce clivage et propose une synthèse explicative.
