Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Automated Negotiation: Prospects, Methods and Challenges

Many autonomous agents operate in domains in which the cooperation of their fellow agents cannot be guaranteed. In such domains negotiation is essential to persuade others of the value of co-operation. This paper describes a general framework for negotiation in which agents exchange proposals backed by arguments which summarise the reasons why the proposals should be accepted. The argumentation is persuasive because the exchanges are able to alter the mental state of the agents involved. The framework is inspired by our work in the domain of business process management and is explained using examples from that domain.

Engineering open environments with electronic institutions

Ideally, open multi-agent systems (MAS) involve heterogeneous and autonomous agents whose interactions ought to conform to some shared conventions. The challenge is how to express and enforce such conditions so that truly autonomous agents can adscribe to them. One way of addressing this issue is to look at MAS as environments regulated by some sort of normative framework. There have been significant contributions to the formal aspects of such normative frameworks, but there are few proposals that have made them operational. In this paper a possible step towards closing that gap is suggested. A normative language is introduced which is expressive enough to represent the familiar types of MAS-inspired normative frameworks; its implementation in JESS is also shown. This proposal is aimed at adding flexibility and generality to electronic institutions by extending their deontic components through richer types of norms that can still be enforced on-line.

Implementing norms in electronic institutions

This report documents the program and the outcomes of Dagstuhl Seminar 15131 “Normative Multi-Agent Systems”. Normative systems are systems in the behavior of which norms play a role and which need normative concepts in order to be described or specified. A normative multi-agent system combines models for normative systems (dealing for example with obligations, permissions and prohibitions) with models for multi-agent systems. Normative multi-agent systems provide a promising model for human and artificial agent coordination because they integrate norms and individual intelligence. They are a prime example of the use of sociological theories in multiagent systems, and therefore of the relation between agent theory—both multi-agent systems and autonomous agents—and the social sciences—sociology, philosophy, economics, legal science, etc. The aim of this Dagstuhl Seminar was to feature two fresh themes in broader computing and software engineering: social computing and governance. These themes are highly interdisciplinary, bringing together research strands from computing, information sciences, economics, sociology, and psychology. Further there is considerable excitement about these areas in academia, industry, and public policy organizations. Our third theme was agreement technologies, a more traditional topic but nonetheless relevant for the NorMAS community. A norm is a fundamental social construct. Norms define the essential fabric of a society. Our purpose in this seminar was to explore the connections of norms to each of the themes, especially from a computational perspective. Moreover, the seminar has been conceived for the writing of a volume titled “Handbook of Normative Multi Agent Systems” aimed to become a standard reference in the field and to provide guidelines for future research in normative multi-agent systems.
