Peri-urbanisation, Social Heterogeneity and Ecological Simplification

Peri-urban development pressure on and near Australian coastlines is resulting in the conversion of agricultural land for rural-residential use. The impact of larger and more diverse human populations upon the ecological assets remaining in agricultural landscapes has consequently become a policy concern. This paper contributes to these policy debates by integrating the results of parallel social and ecological research projects commissioned to improve natural resource management in peri-urbanising regions. The research was undertaken in the case study region of South East Queensland, the region supporting Australia’s most rapid population growth. Our results indicate that both social and ecological communities cross a fragmentation threshold due to peri-urban development whereby they become ecologically simple and socially heterogeneous in a coupling that cedes a poor diagnosis for biodiversity retention.stored soil water, dryland grain cropping, extension, social systems, RD&E, differentiation

Open Source, Modular Platforms, and the Challenge of Fragmentation

Open source and modular platforms represent two powerful conceptual paradigms that have fundamentally transformed the software industry. While generally regarded complementary, the freedom inherent in open source rests in uneasy tension with the strict structural requirements required by modularity theory. In particular, third party providers can produce noncompliant components, and excessive experimentation can fragment the platform in ways that reduce its economic benefits for end users and app providers and force app providers to spend resources customizing their code for each variant. The classic solutions to these problems are to rely on some form of testing to ensure that the components provided by third parties comply with a compatibility standard and to subject the overall system to some form of governance. The history of the three leading open source operating systems (Unix, Symbian, and Linux) confirms this insight. The question is thus not whether some constraints will apply, but rather how restrictive those constraints will be. Finally, the governance regimes range from very restrictive to relatively open and permissive. Competition policy authorities should take into account where certain practices fall along that spectrum when enforcing competition law. Exposing the more permissive practices to demanding scrutiny runs the risk of causing operating systems to turn to more restrictive approaches

Developing an Industrial IoT Platform – Trade-off between Horizontal and Vertical Approaches

Demands for a digitalized, connected, and smart production provide a fertile ground for industrial Internet-of-Things (IIoT) platforms to arise within the manufacturing industry (e.g., Siemens Mind Sphere, AXOOM Smart Enterprise, FORCAM FORCE). Nevertheless, many companies struggle to successfully kick-off platform ecosystems. Information Systems (IS) literature is of limited help, because insights on managing platform ecosystems are mostly derived from successful examples in the business-to-consumer (B2C) context. To better understand the challenging situation of companies in the emerging IIoT environment, we conducted an in-depth case study at a prospective platform provider. Insights gained through interviews and engagement in the field uncovered a tension between a horizontal platform strategy and vertical integrated solutions as a central challenge for companies aiming to launch an IIoT-platform in the market. By conceptualizing this trade-off, its causes along with related benefits and challenges, we add to existing literature on platform governance and launch strategies

Redescribing Health Privacy: The Importance of Health Policy

Current conversations about health information policy often tend to be based on three broad assumptions. First, many perceive a tension between regulation and innovation. We often hear that privacy regulations are keeping researchers, companies, and providers from aggregating the data they need to promote innovation. Second, aggregation of fragmented data is seen as a threat to its proper regulation, creating the risk of breaches and other misuse. Third, a prime directive for technicians and policymakers is to give patients ever more granular methods of control over data. This article questions and complicates those assumptions, which I deem (respectively) the Privacy Threat to Research, the Aggregation Threat to Privacy, and the Control Solution. This article is also intended to enrich our concepts of “fragmentation” and “integration” in health care. There is a good deal of sloganeering around “firewalls” and “vertical integration” as idealized implementations of “fragmentation” and “integration” (respective). The problem, though, is that terms like these (as well as “disruption”) are insufficiently normative to guide large-scale health system change. They describe, but they do not adequately prescribe. By examining those instances where: a) regulation promotes innovation, and b) increasing (some kinds of) availability of data actually enhances security, confidentiality, and privacy protections, this article attempts to give a richer account of the ethics of fragmentation and integration in the U.S. health care system. But, it also has a darker side, highlighting the inevitable conflicts of values created in a “reputation society” driven by stigmatizing social sorting systems. Personal data control may exacerbate social inequalities. Data aggregation may increase both our powers of research and our vulnerability to breach. The health data policymaking landscape of the next decade will feature a series of intractable conflicts between these important social values

Forest fragmentation and its potential implications for the management of the Tarumã-Açu River basin, Central Amazon, Brazil

A intensificação do desmatamento e a consequente fragmentação da paisagem natural em bacias hidrográficas urbanas e periurbanas afetam todo o sistema eco-hidrológico, aumentando a necessidade de entendimento de como essas mudanças podem impactar sua sustentabilidade. Nesse sentido, o presente estudo avaliou as potenciais implicações da fragmentação florestal para a gestão da bacia do Tarumã-Açu, a partir da caracterização dos padrões estruturais e funcionais da paisagem. Para tanto, realizou-se o mapeamento e a categorização dos fragmentos florestais da bacia, a partir da classificação supervisionada (Método Bhattacharyya) de imagem Landsat/OLI, e, posteriormente, o cálculo de métricas da paisagem (área, densidade e tamanho, bordas, forma, área central, isolamento e conectividade). As métricas mostraram uma paisagem bastante fragmentada, especialmente na região do baixo curso da bacia, que concentra os menores, mais dispersos e vulneráveis fragmentos, mesmo em unidades de conservação. Já a região da cabeceira possui os maiores fragmentos, com grande quantidade de área central e alta conectividade estrutural e funcional, fundamentais para a sustentabilidade da bacia e que, portanto, merecem atenção e priorização dos gestores. Os resultados oferecem subsídios importantes e dados inéditos que podem contribuir para a elaboração do plano de gestão da bacia e para a definição de estratégias de conservação e restauração dos remanescentes florestais, indicando áreas prioritárias para implementação dessas ações.The intensification of deforestation and the consequent fragmentation of the natural landscape in urban and periurban watersheds affect the entire eco-hydrological system, increasing the need to understand how these changes can affect their sustainability. In this sense, the present study evaluated the potential implications of forest fragmentation for the management of the Tarumã-Açu basin, based on the characterization of the structural and functional patterns of the landscape. For this, we mapped and categorized the basin’s forest fragments, based on the supervised classification (Bhattacharyya Method) of Landsat/OLI image, and, subsequently, we calculated the landscape metrics (area, density and size, edge, form, core, isolation and connectivity). The metrics showed a very fragmented landscape, especially in the region of the basin’s low course, which concentrates the smallest, most dispersed, and vulnerable fragments even in conservation units. The headwater region, on the other hand, has the largest patches, with a large amount of central area and high structural and functional connectivity, which are fundamental for the sustainability of the basin and, therefore, deserve attention and prioritization by managers. The results offer important subsidies and unpublished data that can contribute to elaboration of the basin’s management plan and for the definition of conservation and restoration strategies of the forest remnants, indicating priority areas for the implementation of these actions

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

Stakeholder Perceptions of Current Planning, Assessment and Science Initiatives in Canada’s Beaufort Sea

Over the past 30 years, the Beaufort Sea has been the site of many regional studies and planning efforts. Currently, three major initiatives are underway: the Integrated Regional Impact Study, which focuses on science; the Integrated Ocean Management Plan; and the Beaufort Regional Environmental Assessment. Despite the mounting pressures for offshore energy development in the region, little attention has been given to whether these initiatives facilitate a more coordinated and informed approach to planning, assessment, and decision making for such development. We examined stakeholder perceptions of the existing initiatives to ascertain whether and how they enable horizontal and vertical integration and how effectively they facilitate marine resource planning and decision making. The results show that three essentials of a more coordinated regional approach to planning for marine resources and offshore development are horizontal integration between management bodies, vertical integration from the strategic level and regional scale to the operational level and project scale, and an overarching vision for regional planning and development in the Beaufort Sea.Ces 30 dernières années, la mer de Beaufort a fait l’objet de nombreuses études régionales et de nombreux efforts de planification régionaux. En ce moment, trois grandes initiatives sont en cours : l’étude intégrée d’impact régional, qui est axée sur la science; le plan intégré de gestion de l’océan; et l’Évaluation environnementale régionale de Beaufort. Même si les pressions exercées en vue de la mise en valeur énergétique au large de cette région se font de plus en plus grandes, peu d’attention a été accordée à la possibilité de déterminer si ces initiatives facilitent une approche plus coordonnée et informée en matière de planification, d’évaluation et de prise de décisions relativement à une telle mise en valeur. Nous avons examiné les perceptions des diverses parties prenantes afin d’établir si et comment elles donnent lieu à l’intégration verticale et horizontale, et dans quelle mesure elles favorisent la planification des ressources de la mer et la prise de décisions à leur sujet. Selon les résultats, une approche régionale plus coordonnée en matière de planification des ressources de la mer et de mise en valeur au large comporte trois éléments essentiels, soit : l’intégration horizontale des organismes de gestion; l’intégration verticale, du niveau stratégique et de l’échelle régionale jusqu’au niveau opérationnel et à l’échelle du projet; et une vision déterminante en matière de planification régionale et de mise en valeur de la mer de Beaufort

Integrating Data and Service Lifecycle for Smart Service Systems Engineering: Compilation of a Lifecycle Model for the Data Ecosystem of Smart Living

In smart service systems engineering, where actors rely on the mutual exchange of data to create complex and holistic solutions, integration is crucial. Nevertheless, the management of data as a driving resource still lacks organizational structure. There is no holistic lifecycle approach that integrates data and service lifecycle and adopts a cross-actor perspective. Especially in data ecosystems, where sovereign actors depend on the mutual exchange of data to create complex, but transparent service systems, an integration is of crucial importance. This particularly applies to the smart living domain, where different industries, products and services interact in a complex environment. In this paper we address this shortcoming by proposing an integrated model that covers the different relevant lifecycles based on a systematic literature review and supplement it by concrete domain requirements from the smart living ecosystem obtained through semi-structured expert interviews
