    Information literacy and peer-to-peer infrastructures: An autopoietic perspective

    This article argues that an autopoietic perspective of human communities would allow to understand societies as self-organized systems and thus promote information literacy as a facilitator of social development. Peer-to-peer (P2P) social dynamics generate public information available worldwide in digital repositories, websites and bibliographic resources. However, processing such amount of data is not achievable by a single central-controlled system. We claim that distributed and heterogeneous networks of coordinated mechanisms, composed by both specialized human and artificial agents, are needed to improve information retrieval, knowledge inference and decision-making, but also to produce social value, goods and services. Handling these issues implies the collective construction of global semantic networks but also the active labor of knowledge producers and consumers. We conclude that information literacy is as much important as any technical implementation and, therefore, may lead to networks of Commons-oriented communities which would utilize P2P infrastructuresVasilis Kostakis acknowledges funding for facilities used in this research by IUT (19-13) of the Estonian Ministry of Education and Researc

    Coalition based approach for shop floor agility – a multiagent approach

    Get PDF
    Dissertation submitted for a PhD degree in Electrical Engineering, speciality of Robotics and Integrated Manufacturing from the Universidade Nova de Lisboa, Faculdade de Ciências e TecnologiaThis thesis addresses the problem of shop floor agility. In order to cope with the disturbances and uncertainties that characterise the current business scenarios faced by manufacturing companies, the capability of their shop floors needs to be improved quickly, such that these shop floors may be adapted, changed or become easily modifiable (shop floor reengineering). One of the critical elements in any shop floor reengineering process is the way the control/supervision architecture is changed or modified to accommodate for the new processes and equipment. This thesis, therefore, proposes an architecture to support the fast adaptation or changes in the control/supervision architecture. This architecture postulates that manufacturing systems are no more than compositions of modularised manufacturing components whose interactions when aggregated are governed by contractual mechanisms that favour configuration over reprogramming. A multiagent based reference architecture called Coalition Based Approach for Shop floor Agility – CoBASA, was created to support fast adaptation and changes of shop floor control architectures with minimal effort. The coalitions are composed of agentified manufacturing components (modules), whose relationships within the coalitions are governed by contracts that are configured whenever a coalition is established. Creating and changing a coalition do not involve programming effort because it only requires changes to the contract that regulates it

    A social contract with business as the basis for a postmodern MBA in a world order of inclusive globalisation : a critical metasynthesis

    This thesis addresses the paradigm shift required for an MBA qualification in a world order of inclusive globalisation (WOIG) – where humankind‟s security is assured, and where global poverty has been eradicated. A new research methodology, termed critical metasynthesis, which is the enrichment of critical management research with metasynthesis and Socrates‟ dialectic method of systematic inquiry has been used. The critical metasynthesis derives its outcome from the insights of global leaders from the developed and developing world, refuted by Nobel Laureates from the past decade. From the Socratic dialogue an end-purpose Statement of Visions for a new world order, society, business, business leadership, and the postmodern MBA emerged, namely: to deliver a WOIG; requiring a society that finds its greatness in protecting both its humanity and its economy as a whole; requiring world-class businesses – financially robust across business cycles, with global stewardship as the dominant business logic; requiring global business leaders with an ability to envision the WOIG, and then to lead thereto in an entrepreneurial and path-breaking manner exerting leadership qualities associated with the golden Rule of Humanity; requiring an MBA that educates and inspires the business leader to lead (and, to co-lead with societal and political leaders) the planetary turn-around to a WOIG. For this, a fundamental change of paradigm for the MBA emerged as a prerequisite. The first prerequisite is a Social Contract with Business as a trichotomy of global business responsibility towards society, politics and the Earth. This, becomes the raison d‟être of the postmodern MBA. The second prerequisite is an educational context aligned with the values and aspirations of a WOIG society. The outcome of the postmodern MBA is a fundamental personal re-orientation as thé kairos moment - through holistic critical reasoning excellence and achieving a WOIG mindset. Flowing from this to craft, build and to manage enterprises for the turn-around from today‟s world order of destructive globalisation to a WOIG. The thesis contributes a new educational context, vocabulary, and guidelines for a new canon of MBA knowledge. The thesis concludes by describing new vistas of follow-up research in four interlocking priorities for the professoriate, namely: discovering, integrating, applying and teaching a postmodern MBA in a WOIG – to deliver MBA graduates who can lead any business in any industry sector in any country towards positive sustained results for all stakeholders.Business LeadershipD.B.L

    Organization based multiagent architecture for distributed environments

    Get PDF
    [EN]Distributed environments represent a complex field in which applied solutions should be flexible and include significant adaptation capabilities. These environments are related to problems where multiple users and devices may interact, and where simple and local solutions could possibly generate good results, but may not be effective with regards to use and interaction. There are many techniques that can be employed to face this kind of problems, from CORBA to multi-agent systems, passing by web-services and SOA, among others. All those methodologies have their advantages and disadvantages that are properly analyzed in this documents, to finally explain the new architecture presented as a solution for distributed environment problems. The new architecture for solving complex solutions in distributed environments presented here is called OBaMADE: Organization Based Multiagent Architecture for Distributed Environments. It is a multiagent architecture based on the organizations of agents paradigm, where the agents in the architecture are structured into organizations to improve their organizational capabilities. The reasoning power of the architecture is based on the Case-Based Reasoning methology, being implemented in a internal organization that uses agents to create services to solve the external request made by the users. The OBaMADE architecture has been successfully applied to two different case studies where its prediction capabilities have been properly checked. Those case studies have showed optimistic results and, being complex systems, have demonstrated the abstraction and generalizations capabilities of the architecture. Nevertheless OBaMADE is intended to be able to solve much other kind of problems in distributed environments scenarios. It should be applied to other varieties of situations and to other knowledge fields to fully develop its potencial.[ES]Los entornos distribuidos representan un campo de conocimiento complejo en el que las soluciones a aplicar deben ser flexibles y deben contar con gran capacidad de adaptación. Este tipo de entornos está normalmente relacionado con problemas donde varios usuarios y dispositivos entran en juego. Para solucionar dichos problemas, pueden utilizarse sistemas locales que, aunque ofrezcan buenos resultados en términos de calidad de los mismos, no son tan efectivos en cuanto a la interacción y posibilidades de uso. Existen múltiples técnicas que pueden ser empleadas para resolver este tipo de problemas, desde CORBA a sistemas multiagente, pasando por servicios web y SOA, entre otros. Todas estas mitologías tienen sus ventajas e inconvenientes, que se analizan en este documento, para explicar, finalmente, la nueva arquitectura presentada como una solución para los problemas generados en entornos distribuidos. La nueva arquitectura aquí se llama OBaMADE, que es el acrónimo del inglés Organization Based Multiagent Architecture for Distributed Environments (Arquitectura Multiagente Basada en Organizaciones para Entornos Distribuidos). Se trata de una arquitectura multiagente basasa en el paradigma de las organizaciones de agente, donde los agentes que forman parte de la arquitectura se estructuran en organizaciones para mejorar sus capacidades organizativas. La capacidad de razonamiento de la arquitectura está basada en la metodología de razonamiento basado en casos, que se ha implementado en una de las organizaciones internas de la arquitectura por medio de agentes que crean servicios que responden a las solicitudes externas de los usuarios. La arquitectura OBaMADE se ha aplicado de forma exitosa a dos casos de estudio diferentes, en los que se han demostrado sus capacidades predictivas. Aplicando OBaMADE a estos casos de estudio se han obtenido resultados esperanzadores y, al ser sistemas complejos, se han demostrado las capacidades tanto de abstracción como de generalización de la arquitectura presentada. Sin embargo, esta arquitectura está diseñada para poder ser aplicada a más tipo de problemas de entornos distribuidos. Debe ser aplicada a más variadas situaciones y a otros campos de conocimiento para desarrollar completamente el potencial de esta arquitectura

    Alternative timelines: Counterfactuals as an approach to design pedagogy

    Counterfactual histories modify the outcome of a historical event and then extrapolate an alternative version of history. In literature, imaginaries based on a counterfactual history can offer thought-provoking insights on contemporary life:   It’s America in 1962. Slavery is legal once again. The few Jews who still survive hide under assumed names. In San Francisco the I Ching is as common as the Yellow Pages. All because some 20 years earlier the United States lost a war and is now occupied jointly by Nazi Germany and Japan. (Dick, 1992)   The Man in the High Castle describes the consequences of one popular starting point for counterfactual histories, Germany winning World War II. Historians tend to focus on military "decision points" at which events could have taken another path (Bernstein, 2000), or they imagine the absence of powerful individuals to speculate on how things might have been different. Since history is “often written by the victors, it tends to ‘crush the unfulfilled potential of the past’, as Walter Benjamin so aptly put it. By giving a voice to the ‘losers’ of history, the counterfactual approach allows for a reversal of perspectives” (Deluermoz & Singaravélou, 2021). A counterfactual approach offers much potential as a methodology for practice-based design research and pedagogy – designers typically design for the world as it is rather than as it could be (Dunne & Raby, 2013). Design happens within entrenched systems whose foundations in many cases were laid centuries ago. Systems of economy, infrastructure and popular culture inform and constrain design methods, motivations and approaches to the evaluation of designed artefacts. Technological advances are applied via these rules, facilitating the iterative development of products and providing a neat lineage from the past and, more importantly, into the future (Auger et al, 2017). This version of design is increasingly being revealed as fundamentally flawed – highly successful in placating shareholders, it is not fit for purpose where ethical or environmental issues are concerned.   Counterfactuals provide an almost surreptitious method of combining design theory with practice. Through a rigorous analysis of history, the designer identifies key elements that are problematic when viewed through a contemporary lens. The approach can expose dominant structures of power and the influence these have on design culture and metrics: for example, the influence of legacy systems and how they limit the imagination and reveal the hidden or unexpected historical events that influenced the timeline. In A New Scottish Enlightenment, Mohammed J. Ali proposes a different outcome to the 1979 Scottish independence referendum (Debatty, 2014). A “yes” vote leads to the creation of a new Scottish government, whose ultimate goal is the delivery of energy independence and a future free from fossil fuels. The project was exhibited shortly before the 2014 referendum. This starting point (a yes or no vote) resonates because it vividly presents a life that could have been. It makes us think about the power of our vote and the potential implications of a “bad choice”. The second aspect that gives the project wider relevance is the agenda used to drive extrapolation from its fictional starting point – a simple paradigm shift on energy generation and distribution. By defining energy independence as a national goal, it becomes possible to outline the ways this might happen. Important earlier examples of a counterfactual approach to design include Pohflepp and Chambers (Auger, 2012; Dunne & Raby, 2013).   Here is a rough summary of a counterfactual design methodology:   1.      The approach begins with the choice of subject – what is to be designed and the creation of a detailed and diverse timeline of its history. 2.      The identification of key moments that have led to the state of things; in particular the elements that could be critiqued from alternative value systems. 3.      The creation of a counterfactual timeline based on numerous possibilities – this is the key difference in method between historiography and design. The approach facilitates the creation of new value systems, motivations, rules and constraints that can be applied in practice. 4.      The design of things along the new timeline; it can be furnished at key moments with artefacts informed by the alternative rules.   A recent Master’s project at the École normale supérieure Paris-Saclay followed this brief. Themes included rethinking approaches to aging based on the elimination of the royalist doctrines of 18th century France; a counterfactual history of agriculture with the tool acting as intermediary between the person working and their environment; and the archive – an examination of the modalities for a deployment of queer, feminist and trans-feminist archive design forms in everyday life. With its focus on underrepresented groups and unrealised possibilities, this last concept resonates with a broader discourse about decolonising design. What alternative value systems and approaches to design might have emerged if 20th-century design history had not been defined by the works of Morris, Dreyfus, Bel Geddes, Gropius, Rams, Starck, Ives, Dyson, and the rest?   Taking up Benjamin’s point about “the unfulfilled potential of the past”, the most vital use of counterfactuals in design is to allow different voices to emerge that were drowned out by dominant or “standard” narrative(s). Recognising alternative histories can open up valuable future paths and create space for new possibilities and imaginaries to flourish. Works Cited   Auger, James (2012). Why Robot?
