Non-functional Data Collection for Adaptive Business Processes and Decision Making

International audienceMonitoring application services becomes more and more a transverse key activity in SOA. Beyond traditional human system administration and load control, new activities such as autonomic management as well as SLA enforcement raise the stakes over monitoring requirements. In this paper, we address a new monitoring-based activity which is selecting among competitive service offers based on their currently measured QoS. Starting from this use case, the late binding of service calls in SOA given the current QoS of a set of candidate services, we first elicit the requirements and then describe M4ABP (Monitoring for Adaptive Business Process), a middleware component for monitoring services and delivering monitoring data to business processes wishing to call them. M4ABP provides solutions for general requirements: flexibility as well as performance in data access for clients, coherency of data sets and network usage optimization. Lessons learned from this first use case can be applied to similar monitoring scenario, as well as to the larger field of context-aware computing

Digital Ecosystems: Ecosystem-Oriented Architectures

We view Digital Ecosystems to be the digital counterparts of biological ecosystems. Here, we are concerned with the creation of these Digital Ecosystems, exploiting the self-organising properties of biological ecosystems to evolve high-level software applications. Therefore, we created the Digital Ecosystem, a novel optimisation technique inspired by biological ecosystems, where the optimisation works at two levels: a first optimisation, migration of agents which are distributed in a decentralised peer-to-peer network, operating continuously in time; this process feeds a second optimisation based on evolutionary computing that operates locally on single peers and is aimed at finding solutions to satisfy locally relevant constraints. The Digital Ecosystem was then measured experimentally through simulations, with measures originating from theoretical ecology, evaluating its likeness to biological ecosystems. This included its responsiveness to requests for applications from the user base, as a measure of the ecological succession (ecosystem maturity). Overall, we have advanced the understanding of Digital Ecosystems, creating Ecosystem-Oriented Architectures where the word ecosystem is more than just a metaphor.Comment: 39 pages, 26 figures, journa

A function-based typology for Earth’s ecosystems

As the United Nations develops a post-2020 global biodiversity framework for the Convention on Biological Diversity, attention is focusing on how new goals and targets for ecosystem conservation might serve its vision of ‘living in harmony with nature’1,2. Advancing dual imperatives to conserve biodiversity and sustain ecosystem services requires reliable and resilient generalizations and predictions about ecosystem responses to environmental change and management3. Ecosystems vary in their biota4, service provision5 and relative exposure to risks6, yet there is no globally consistent classification of ecosystems that reflects functional responses to change and management. This hampers progress on developing conservation targets and sustainability goals. Here we present the International Union for Conservation of Nature (IUCN) Global Ecosystem Typology, a conceptually robust, scalable, spatially explicit approach for generalizations and predictions about functions, biota, risks and management remedies across the entire biosphere. The outcome of a major cross-disciplinary collaboration, this novel framework places all of Earth’s ecosystems into a unifying theoretical context to guide the transformation of ecosystem policy and management from global to local scales. This new information infrastructure will support knowledge transfer for ecosystem-specific management and restoration, globally standardized ecosystem risk assessments, natural capital accounting and progress on the post-2020 global biodiversity framework

From product to service design: A thinking paradigm shift

The economy, society and industry are experiencing change by a shift from products to services. It is apparent that this also brings an on-going ‘conceptual shift’ in business and industry characterised by a movement from traditional goods-centred dominant logic to emerging service-centred dominant logic. While a “problem solving” approach is commonly used for the development of products, as the primary unit of exchange moving from goods to service, new design approaches for the development of services are needed. The diverse nature of services in comparison to products, where service are specialised competences such as knowledge and skills that people can acquire and exchange, highlight the need for new design approaches. This research argues that a fundamental transformation in the design world is taking place, manifested in a thinking paradigm shift from problem solving (designing products) towards system thinking (designing services). Furthermore, the very own nature of products has also changed. From being purely physical and tangible entities, they are becoming mixed entities, with both physical and virtual (or intangible) attributes. Also, from being individual objects that stand alone, products now are part of complex systems, becoming the touch points (TP) of a service. The touch points include interactive properties that allow people that use them (users) to exchange information in and out, acting as enablers in the communication between the service providers and users. These changes have direct implications in the activity of designers, and in the way designers approach problems and issues

Structuring the European Administrative Space - Channels of EU Penetration and Mechanisms ofNational Change

The author provides an analytical model to capture mechanisms of supranational impact on national public administrations. The aim is to understand how we can perceive a European administrative space given the persistent diversity between member states. In face of the overly complex subject matter, it is argued that a typology that presents ideal types of interaction modes between supranational and national levels of administration provides in fact a suitable pragmatic approach to understand the potential impact of European integration on national civil services. Scrutinizing which mechanisms of possible influence-taking the European Union (EU) invokes shows that administrative integration does actually not suggest overall convergence. Instead the shared administrative space works precisely because it preserves state-sensitive diversity. Only in the context of enlargement did the EU need to present a single model to the candidate states and thus the notion of an ever more converging single administrative space was invented. Despite the external promotion of a single model, the driving dynamic of the emerging European administrative space remains increased cooperation and common administration that respects and sustains differences between independent national public administrations. The theoretical framework and empirical application therefore provide a first step for further research to tackle how supranational integration changes national public administration.public administration; identity; ideas; integration theory; public administration; closer cooperation; Europeanization; Europeanization

Ecological Kinds and the Units of Conservation

Conservation has often been conducted with the implicit internalization of Aldo Leopold’s claim: “A thing is right when it tends to preserve the integrity, stability and beauty of the biotic community.” This position has been found to be problematic as ecological science has not vindicated the ecological community as an entity which can be stable or coherent. Ecological communities do not form natural kinds, and this has forced ecological scientists to explain ecology in a different manner. Individualist approaches to ecological systems have gained prominence. Individualists claim that ecological systems are better explained at the population level rather than as whole communities. My thesis looks at the implications of the current state of ecological science on conservation biology and emphasizes the importance of biodiversity as assessed at the population level. I defend the position that biodiversity should represent taxonomy and be quantified in reference to phylogenetic structure. This is a defence of biodiversity realism, which conceives of biodiversity as a natural quantity in the world which is measurable, valuable to prudent agents, and causally salient to ecological systems. To address how biodiversity at the population level relates to larger ecological systems I create a methodology designed to identify the relevant ecological system which biodiversity maintains and is maintained by biodiversity. This is done through the context dependent modelling of causal networks indexed to populations. My causal modelling methodology is then utilized to explicate ecological functions. These chapters together provide a framework for conservation science, which can then be applied to novel problems. The final section of the thesis utilises this framework to address whether de-extinction is a worthwhile conservation technique
