Agent-based models and individualism: is the world agent-based?

Agent-based models (ABMs) are an increasingly popular tool in the social sciences. This trend seems likely to continue, so that they will become widely used in geography and in urban and regional planning. We present an overview of examples of these models in the life sciences, economics, planning, sociology, and archaeology. We conclude that ABMs strongly tend towards an individualist view of the social world. This point is reinforced by closer consideration of particular examples. This discussion pays attention to the inadequacy of an individualist model of society with reference to debates in social theory. We argue that because models are closed representations of an open world it is important that institutions and other social structures be explicitly included, or that their omission be explained. A tentative explanation for the bias of ABMs is offered, based on an examination of early research in artificial intelligence and distributed artificial intelligence from which disciplines the approach is derived. Some implications of these findings are discussed. We indicate some useful research directions which are beginning to tackle the individualism issue directly. We further note that the underlying assumptions of ABMs are often hidden in the implementation details. We conclude that such models must be subject to critical examination of their assumptions, and that model builders should engage with social theory if the approach is to realise its full potential

Ontology of multi-agents processes of spatial decision

In the paper of Cavezzali, Girotti and Rabino presented at ERSA 2003 conference, features of multi-agent models and their potentiality for the study of territorial phenomena are discussed. Starting from this study, the present paper digs deeper mechanisms of multi-agent systems working, describing their ontology in a more complete and articulated way as possible, and investigating: the properties of the actors, the mechanisms of interaction among actors and between actors and environment. About the environment, particular attention has been paid to the consideration about the various modalities of treatment of territory (from pure physical support to active reactive/cognitive agent in relationship with the other agents). For these modalities, finally, two typical case-studies of multi-agent model are shown: simulation of pedestrian paths choice, the software “Turisti”, and a competitive dynamic of service centres location, “Wilson”.

Social Media for Cities, Counties and Communities

Social media (i.e., Twitter, Facebook, Flickr, YouTube) and other tools and services with user- generated content have made a staggering amount of information (and misinformation) available. Some government officials seek to leverage these resources to improve services and communication with citizens, especially during crises and emergencies. Yet, the sheer volume of social data streams generates substantial noise that must be filtered. Potential exists to rapidly identify issues of concern for emergency management by detecting meaningful patterns or trends in the stream of messages and information flow. Similarly, monitoring these patterns and themes over time could provide officials with insights into the perceptions and mood of the community that cannot be collected through traditional methods (e.g., phone or mail surveys) due to their substantive costs, especially in light of reduced and shrinking budgets of governments at all levels. We conducted a pilot study in 2010 with government officials in Arlington, Virginia (and to a lesser extent representatives of groups from Alexandria and Fairfax, Virginia) with a view to contributing to a general understanding of the use of social media by government officials as well as community organizations, businesses and the public. We were especially interested in gaining greater insight into social media use in crisis situations (whether severe or fairly routine crises, such as traffic or weather disruptions)

An international collaboration for the development of a research training course in an emergent academic discipline

Proceedings of INTED2010 Conference. 8-10 March 2010, Valencia, Spain.In professional areas such as the creative and performing arts and design, the academic model of research has not been clearly articulated. This means that often the values held in advanced professional practice run counter to the traditional models of knowledge and research that are adopted in academia. As a result, there is a problem in accounting for research in these areas in ways that will be recognised and valued by both communities. There is an ongoing debate about the best way of dealing with and reflecting these professional values in academic research. This debate has substantiated an emergent type of research that is called ‘Practice-based Research’ (PbR). PbR introduces the claim that creative practice has an instrumental role in academic research in areas such as design and urban planning. This role is different from the one of experimentation in traditional empirical research, and different from the one of practice in professional creative practice. This paper describes the development and delivery of a research methods training course in the department of spatial planning and design (Stedenbouw) at the Technical University Delft (TU Delft, Netherlands) that engages directly with these fundamental problems. The course, Research and Design Methods, has served as a testing ground for many ideas stemming from the cooperation between TU Delft and the University of Hertfordshire (UH, UK). As part of the international knowledge transfer initiative, a member of staff from TU Delft has been working at the UH for a year. One of the outcomes of this collaboration is the design and delivery of a new course at TU Delft, which tackles the relationship between academic research and planning and design, through a dialogue between different views on the activities of the urban planner and the designer. There are challenges that arise when structuring a course within an area for which the epistemological, ontological and methodological questions are still under discussion by the community. The broad aim was to offer insight into non-traditional academic research tools and methods for different areas of urban design and planning within a broader academic context. This included the analysis of different academic traditions that were relevant for urban planning and design. We define research as a systematic investigation of a subject that leads to the production of explicit knowledge, and adds to the existing body of knowledge about the subject. In the paper, we analyse the way in which research and practice are problematized in the TU Delft course and claim that PbR manifests the differences between the worldviews of academic research and professional practice, with their different aims and values. As a result, training and expertise in the professional values of creative practice is insufficient for academic research. There is therefore a need for specific research training that addresses these differences. This need for discipline specific research training has been recognized in the Bologna Process and the TU Delft course represents one such training programme.otherPeer reviewe

A pedagogical proposal in an area of epistemological uncertainty

IV Projetar 2009: PROJETO COMO INVESTIGAÇÃO: ENSINO, PESQUISA E PRÁTICA FAU-UPM SÃO PAULO BRASIL, Outubro 2009In professional areas in which there is an element of design practice, such as architecture and urbanism, the academic model of knowledge has not been clearly articulated. This means that often the values held in professional practice run counter to the traditional models of knowledge and research that are adopted. As a result there is a problem in accounting for research in these areas in ways that will be recognised and valued by both communities. There is an ongoing debate about the best way of dealing with and reflecting these values that are, from the academic viewpoint, non-traditional. The debate has substantiated an emergent type of research that is specific to areas of design practice that is called ‘Practice-based Research’ (PbR). PbR claims that design practice has an instrumental role in research in areas such as design and urban planning. This role is different from the role of experimentation in traditional empirical research, and different from the role of practice in professional design practice. This paper describes the development and delivery of a research methods training course in the department of spatial planning and design (Stedenbouw) at the Technical University Delft (TU Delft, Netherlands) that builds on research by the ‘Non-traditional Knowledge and Communication’ project (NtKC) at the University of Hertfordshire (UK). The paper will analyse the way in which research and practice are problematized in the TU Delft course. We claim that the problem of PbR manifests the differences between the worldviews of academic research and professional practice, with their differing aims and values. As a result, training and expertise in the professional values of design practice is insufficient for academic research, leading to a need for specific training as a researcher that recognises these differences. This need has been accepted at an institutional level in many universities in Europe, and the TU Delft course represents one such training programme
