    Ausubel's meaningful learning re-visited

    Get PDF
    This review provides a critique of David Ausubel’s theory of meaningful learning and the use of advance organizers in teaching. It takes into account the developments in cognition and neuroscience which have taken place in the 50 or so years since he advanced his ideas, developments which challenge our understanding of cognitive structure and the recall of prior learning. These include (i) how effective questioning to ascertain previous knowledge necessitates in-depth Socratic dialogue; (ii) how many findings in cognition and neuroscience indicate that memory may be non-representational, thereby affecting our interpretation of student recollections; (iii) the now recognised dynamism of memory; (iv) usefully regarding concepts as abilities or simulators and skills; (v) acknowledging conscious and unconscious memory and imagery; (vi) how conceptual change involves conceptual coexistence and revision; (vii) noting linguistic and neural pathways as a result of experience and neural selection; and (viii) recommending that wider concepts of scaffolding should be adopted, particularly given the increasing focus on collaborative learning in a technological world

    A Design Science Research Approach to Smart and Collaborative Urban Supply Networks

    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    Unlocking the potential for thermal energy storage in the UK

    Rapid and deep energy system decarbonisation is essential to a safe future. Thermal energy storage may hold the key to significant carbon reduction of the heating, cooling and electricity sectors, but the UK remains largely locked in to a fossil-fuel based heating regime. Global urbanisation trends mean cities are crucial to the net-zero transition. This thesis provides a sociotechnical analysis of current and future thermal storage deployment, recognising that fundamental change is complex and involves individuals and companies, supply chains, infrastructures, markets, policy and regulation, norms and traditions. I explore this through the overarching research question: How can cities unlock the potential for thermal energy storage to support the UK’s net-zero transition? The work is presented through three empirical chapters. A pilot study used a survey, thematic analysis, and pre-existing sociotechnical frameworks to explore the current state of UK thermal storage deployment and how sociotechnical characteristics are shaping current and future deployment prospects. A case study of a particular storage approach known as geoexchange analyses the results of interviews with geoexchange practitioners using sociotechnical frameworks, and proposes a new critical success factors framework. Finally, a comparative case study of two UK cities explores the specific role of local authorities to use powers at their disposal within a common planning framework to support the deployment of urban shared ground heat exchange in residential and mixed-use developments. Based on this study, a framework for local policy, support and enforcement activities is proposed. Applied contributions are provided through new knowledge on sociotechnical factors shaping the prospects for TES to support the net-zero transition, the first sociotechnical analysis of UK geoexchange deployment, and policy and practice proposals to support city-based shared ground heat exchange. Theory is advanced through application, testing and development of several existing frameworks for understanding sociotechnical change. Based on empirical evidence, two novel frameworks are proposed to support deployment of geoexchange and shared ground heat exchange

    Editor's notes. By Margherita Russo. Sebastiano Brusco's collection of essays Piccole imprese e distretti industriali (Tori-no, Rosenberg & Sellier, 1989) was translated in English by Tim Keats in 1990, unless three chapters that were already available in English and chapter 7 that was too long for a publication as a book chapter. Having abandoned the project of publishing a vol-ume in English, Sebastiano Brusco asked me to share a photocopy of the English transla-tion with scholars who requested it, and so several copies arrived in the hands of re-searchers in various countries: South Africa, Norway, Denmark, the United States, France and the United Kingdom. Twenty years after Sebastiano Brusco passed away, and me approaching to retirement, a working paper edition - in the DEMB Working Paper Series - will make the document freely available online. This digital document has been created, in 2012, drawing on a folder of Sebastiano Brusco's digital archive "Backup of EnglishBook" that contained Lotus MS files. These files have been converted by Patrizio Magagni in a txt format and then inserted by me in a single Word file: "Backup of EnglishBook_from files converted by Patrizio_22.01.2012 Some graphs and tables have been added as images, taken from the Italian edition. The text is all flag-formatted, whereas in the Italian edition only the main introduction, chapter introduction and afterword were flag-formatted. The text is not justified be-cause, in the conversion of the original files, a manual line break was automatically inserted at the end of each line. To differentiate those parts of the text written by Brusco specifically for the publi-cation of the 1989 collection of essays, they are reproduced here in two columns, with a smaller font. A complete list of Sebastiano Brusco's publication is available online at:https://www.economia.unimore.it/site/home/dipartimento-di-economia---sebastiano-brusco-web-page.htm

    Bibliographic Control in the Digital Ecosystem

    Get PDF
    With the contributions of international experts, the book aims to explore the new boundaries of universal bibliographic control. Bibliographic control is radically changing because the bibliographic universe is radically changing: resources, agents, technologies, standards and practices. Among the main topics addressed: library cooperation networks; legal deposit; national bibliographies; new tools and standards (IFLA LRM, RDA, BIBFRAME); authority control and new alliances (Wikidata, Wikibase, Identifiers); new ways of indexing resources (artificial intelligence); institutional repositories; new book supply chain; “discoverability” in the IIIF digital ecosystem; role of thesauri and ontologies in the digital ecosystem; bibliographic control and search engines

    Child Obesity and Nutrition Promotion Intervention

    Get PDF
    Childhood obesity continues to be a global problem, with several regions showing increasing rates and others having one in every three children overweight despite an apparent halt or downward trend. Children are exposed to nutritional, social, and obesogenic environmental risks from different settings, and this affects their lifelong health. There is a consensus that high-quality multifaceted smart and cost-effective interventions enable children to grow with a healthy set of habits that have lifelong benefits to their wellbeing. The literature has shown that dietary approaches play key roles in improving children’s health, not only on a nutritional level but also in diet quality and patterns. An association between the nutritional strategy and other lifestyle components promotes a more comprehensive approach and should be envisioned in intervention studies. This Special Issue entitled “Child Obesity and Nutrition Promotion Intervention” combines original research manuscripts or reviews of the scientific literature concerning classic or innovative approaches to tackle this public health issue. It presents several nutritional interventions alongside lifestyle health factors, and outcome indicators of effectiveness and sustainability from traditional to ground-breaking methods to exploit both qualitative and quantitative approaches in tackling child obesity
