    Towards coherence on sustainability in education: a systematic review of Whole Institution Approaches

    Get PDF
    Orienting societies towards sustainability requires comprehensive learning of how to think, act and live within a safe and just space for humanity. Approaching sustainability as a core paradigm of quality education in the twenty-first century, Education for Sustainable Development necessitates an integrated view on learning. For educational organizations, Whole Institution Approaches (WIAs) to sustainability emphasize that all learning is embedded within its socio-physical contexts. Although the core objective—to “walk the talk” on sustainability—is theoretically well established, questions remain regarding its specific conceptualizations. Based on a systematic qualitative analysis of 104 international documents from scientific and grey literature, this article offers a conceptual synthesis of the core elements of WIAs to sustainability in education. Based on the literature analysis, WIAs are described as continuous and participative organizational learning processes aimed at institutional coherence on sustainability, consistently linking the formal and informal (hidden) curricula. While specific pathways are necessary for diverse organizations, the article synthesizes a joint framework. Key characteristics of WIAs are clustered within five core principles (coherence, continuous learning, participation, responsibility, long-term commitment), seven highly integrated areas of action (governance, curriculum, campus, community, research, communication, capacity building), the underlying organizational culture, and critical conditions for successful implementation. As becomes clear from the synthesis, following a WIA means to collaboratively switch the default mode of all rules-in-use to sustainability. The concept of WIAs may thus both be approached as an instrument for consistent organizational development in light of (un-)sustainability and as a keystone of integrated high-quality sustainability learning

    Towards to the Respiritualization of the Economics

    To reflect the economical life is a dynamic and complex process, and that means to adapt the economics to the problems generated by the evolution.The authors stand for the idea that in the present we are the witness of growth the complexity of problems, the emphasis of the interferences and their opening towards time and space of a living conscience belonging to the kind of the “whole integrated”.In accordance with the new trends that shaped the science, the view of the economic life should be realized from the perspective of the “whole living common”. This means to understand economics as an organic part of the natural environment and of the environment created by man, where its functional sense is brought into the harmony by the principles of rationality and hope, by the statement of the “win-win” rules for the whole participants of the living common’s life.The new culture of the economical and social life is founded on the values of freedom and responsibilities, social community and human solidarity, as values integrated under the exigencies of the “assumed freedom”.The value-added in economy, as a new created value is the source to understand the “win-win” principle for the enterprises, people, communities, families, and institutions, including here the keeping of the ecological equilibrium

    Access and privacy control enforcement in RFID middleware systems: Proposal and implementation on the Fosstrak platform

    No full text
    International audienceRadio Frequency IDentification (RFID) technology offers a new way of automating the identification and storing of information in RFID tags. The emerging opportunities for the use of RFID technology in human centric applications like monitoring and indoor guidance systems indicate how important this topic is in term of privacy. Holding privacy issues from the early stages of RFID data collection helps to master the data view before translating it into business events and storing it in databases. An RFID middleware is the entity that sits between tag readers and database applications. It is in charge of collecting, filtering and aggregating the requested events from heterogeneous RFID environments. Thus, the system, at this point, is likely to suffer from parameter manipulation and eavesdropping, raising privacy concerns. In this paper, we propose an access and privacy controller module that adds a security level to the RFID middleware standardized by the EPCglobal consortium. We provide a privacy policy-driven model using some enhanced contextual concepts of the extended Role Based Access Control model, namely the purpose, the accuracy and the consent principles. We also use the provisional context to model security rules whose activation depends on the history of previously performed actions. To show the feasibility of our privacy enforcement model, we first provide a proof-of-concept prototype integrated into the middleware of the Fosstrak platform, then evaluate the performance of the integrated module in terms of execution time

    Query Modification in Object-oriented Database Federation

    Get PDF
    We discuss the modification of queries against an integrated view in a federation of object-oriented databases. We present a generalisation of existing algorithms for simple global query processing that works for arbitrarily defined integration classes. We then extend this algorithm to deal with object-oriented features such as queries involving path expressions and nesting. We show how properties of the OO-style of modelling relationships through object references can be exploited to reduce the number of subqueries necessary to evaluate such querie

    Identification of Design Principles

    Get PDF
    This report identifies those design principles for a (possibly new) query and transformation language for the Web supporting inference that are considered essential. Based upon these design principles an initial strawman is selected. Scenarios for querying the Semantic Web illustrate the design principles and their reflection in the initial strawman, i.e., a first draft of the query language to be designed and implemented by the REWERSE working group I4

    Margin Squeeze: Theory, Practice, Policy

    Get PDF
    Margin squeeze occurs where the margin between the price charged by a vertically integrated firm for a wholesale input, and its own retail price for the end product incorporating the input, is so low as to foreclose one or more affected markets. The extent to which margin squeeze should constitute a discrete competition law offence, distinct from predation or refusal to deal, is a disputed question. A jurisprudential chasm between the approaches to margin squeeze under European Union competition law and United States antitrust has emerged, following the Court of Justice of the European Union’s judgments in Deutsche Telekom and TeliaSonera and the US Supreme Court’s decision in LinkLine. The EU recognises a broad concept of margin squeeze, applicable in any sector; the US does not recognise margin squeeze as a standalone abuse, and moreover, the presence of sector-specific regulation excludes the application of antitrust to the price levels that comprise the squeeze. This paper explores the margin squeeze concept, with particular attention to both areas of contention

    Global constitutionalism and legal theory: a preliminary analysis

    El derecho supranacional presenta fenĂłmenos de fragmentaciĂłn, ademĂĄs de aspectos de constitucionalizaciĂłn. Las teorĂ­as que se ocupan del constitucionalismo global analizan los fenĂłmenos de constitucionalizaciĂłn del derecho supranacional, tal como los requisitos prescriptivos de este proceso. Este artĂ­culo versa sobre las diversas maneras en las que es posible comprender el constitucionalismo global y, sobre todo, analiza su relevancia para la teorĂ­a y el concepto de derecho.Supranational law shows phenomena of fragmentation, as well as aspects of constitutionalization. Theories that deal with global constitutionalism analyze phenomena of constitutionalization of supranational law, as well as the prescriptive requirements of this process. This paper analyzes the different ways in which it is possible to understand global constitutionalism, and in a preliminary way addresses its relevance to the theory and the concept of law

    A lean way of design and production for healthcare construction projects

    Get PDF
    As a consequence of the lack of solid conceptual foundation, the project management concepts and techniques usually applied within the construction sector are fragmented and have proved to be incapable of solving the complex problems of design management. As a result, healthcare providers have become frustrated with the outcomes such as cost and schedule overruns, accidents, less than expected quality and inadequate functionality. However, an investigation of successful healthcare projects reveals that new approaches have been developed to tackle such problems. This study uses recent data based on six construction projects. The idea is demonstrate how successful projects are dealing with the integration between design, production, and operations, through an appropriate approach to the management of production systems. The paper aims to assist the different parties of the AEC industry to better understand how practices applied into design phase could support the efficiency in the management of production systems
