Mobile Computing in Digital Ecosystems: Design Issues and Challenges

In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the construction of what we term a digital ecosystem, i.e., an ecosystem constructed out of so-called digital organisms (see below), that can foster the development of novel distributed services. In this context, a human user equipped with his/her own mobile devices, can be though of as a digital organism (DO), a subsystem characterized by a set of peculiar features and resources it can offer to the rest of the ecosystem for use from its peer DOs. The internal organization of the DO must address issues of management of its own resources, including power consumption. Inside the DO and among DOs, peer-to-peer interaction mechanisms can be conveniently deployed to favor resource sharing and data dissemination. Throughout this paper, we show that most of the solutions and technologies needed to construct a digital ecosystem are already available. What is still missing is a framework (i.e., mechanisms, protocols, services) that can support effectively the integration and cooperation of these technologies. In addition, in the following we show that that framework can be implemented as a middleware subsystem that enables novel and ubiquitous forms of computation and communication. Finally, in order to illustrate the effectiveness of our approach, we introduce some experimental results we have obtained from preliminary implementations of (parts of) that subsystem.Comment: Proceedings of the 7th International wireless Communications and Mobile Computing conference (IWCMC-2011), Emergency Management: Communication and Computing Platforms Worksho

The Land Conservation Plan for Maine’s Piscataqua Region Watersheds

The Piscataqua River/Great Bay estuary is a shared coastal embayment that forms the southernmost boundary between the states of Maine and New Hampshire. This rich coastal bay provides critical ecological, economic, and social benefits to the southern Maine and coastal New Hampshire region. The Great Bay estuary is such an important coastal resource that it is officially recognized as a coastal area of national significance by both the federal National Estuary Program and the federal National Estuarine Research Reserve program. The Piscataqua River/Great Bay estuary is fed by many rivers in New Hampshire, and by the Salmon Falls River, Great Works River, and Spruce Creek water- sheds in Maine. Collectively, the land area that contributes water flow to this treasured bi-state estuarine system is referred to as the “Piscataqua Region.” Within Maine, this region includes portions or all of ten Maine communities: Acton, Berwick, Eliot, Kittery, Lebanon, North Berwick, Sanford, South Berwick, Wells, and York

Newmarket Open Space Conservation Plan

Open spaces – forests, fields, wetlands, floodplains, salt marshes, rivers and streams – are integral to our community. These lands and waters that thread through our neighborhoods are a scenic reminder of our history, when people made their living by working the land. Yet we still depend on these open spaces for our health and our wellbeing. These places provide many “services” such as clean air, flood control, filtering pollutants and purifying drinking water, natural pest control, plant pollination, cooler summer temperatures, and areas for relaxing, exercising and recreating. Collectively these can be thought of as a “natural services network” – a minimum framework or backbone of open spaces that offer these services to all of us regardless of age, income, or points of view. New Hampshire is transforming from a largely rural state to a mostly urban and suburban one. This trend will continue at a rapid pace as the State is expected to grow by 358,000 people (or more than 28%) from 2000 to 2025. Most of this growth will occur in the four southeastern counties, with the Town of Newmarket in the heart of this growth area. The major land use trends include loss of unfragmented forestland, lack of protected lands around public water supplies and aquifers, and loss of intact wetlands and wildlife habitat (SPNHF 2005). Many communities, including the residents of Newmarket, have acknowledged these changes and the need to conserve special places and ecosystems by supporting land use planning tools, natural resource inventories, conservation funds, and stewardship of lands. Since 2001, 83 New Hampshire towns have passed open space bond issues or appropriated funds for land acquisition worth more than $135 million (NH Center for Land Conservation Assistance). In 2002, Newmarket residents overwhelmingly passed a$2 million land acquisition bond. Landowners in our community have generously donated interest in land or easements to ensure that conservation values are protected in perpetuity. This support for land and water conservation that benefits all of us is a tribute to the community land ethic in our region. The Town of Newmarket boasts a rich diversity of natural habitats and associated plants and animals. The Lamprey and Piscassic Rivers, Great Bay Estuary, and Tuttle Swamp, to name just a few, all contribute to the sense of place and allure of the town (Map 1). Balancing the preservation of open space with responsible development, long maintained as a priority by Newmarket citizens, business owners and town officials, is necessary, as growth and all its requisite accompaniments present increasing challenges. Recent concerns about the availability of drinking water for Newmarket residents and businesses as well as the floods of 2006 reflect these challenges. As Newmarket continues to grow, so will concern over loss of natural areas, recreational opportunities, and the quality of life that residents have long enjoyed. Maintaining a network of rivers and wetlands, forests and fields throughout Newmarket for the health of the land and people requires vision, support, and action. In 1991, the Town of Newmarket hired the Smart Associates to prepare a Natural Resource Inventory and Conservation Plan. This was the beginning of efforts by the Conservation Commission to conserve important lands identified in the “Smart Report.” In the fifteen years that have elapsed since the Smart Report, Newmarket has undergone many changes, highlighting the need to revisit the current state of natural resources within the community. The Open Space Commission and Conservation Commission have led recent efforts to identify and protect conservation and recreation areas. The Planning Board and staff have led in creating effective land use planning tools that conserve open spaces while allowing orderly and thoughtful development. Together, Newmarket Open Space Conservation Plan Page 7 of 94 these boards applied for a grant from the NH Estuaries Project (NHEP) Technical Assistance Program in 2006 to develop an Open Space Plan. The NHEP awarded the grant of $6,200 to Ibis Wildlife Consulting to work with the Town of Newmarket to prepare this Plan

Reference Model and Architecture for the Post-Platform Economy

The primary goal of this thesis is to propose a reference model and an accompanying software system architecture, which together can serve as a guiding framework for the analysis, design, and implementation of distributed market spaces. The benefit of such a framework is considered two-fold: On the one hand, it provides insights essential for understanding various aspects and elements of self-organized and strictly decentralized online structures to facilitate the emergence of the post-platform economy. On the other hand, it serves as a blueprint for designing and implementing a distributed marketplace instance for a specific application context. It thus allows consumers and providers to set up and expand market spaces themselves, in which they can engage directly and reliably with complex product scenarios

The Invisible Forest: Conservation Easement Databases and the End of the Clandestine Conservation of Natural Lands

Olmsted talks about invisible forest refers to forest lands -- and, for that matter, any other land types -- protected by a perpetual conservation easement, the existence and location of which are concealed from the public, whether deliberately or because of the opaque nature of the easement process. Because easements, like other forms of deeds, must be recorded at the local land registry or recorder\u27s office, they can never be made undiscoverable. But, despite the efforts of some states and conservation organizations to compile conservation easement data for public consumption, there are few functional systems that comprehensively track and provide easy access to conservation easement data

Transformation of German IT Infrastructure Sales Ecosystems during the Course of Digitalisation

The businesses of IT infrastructure product and service manufacturers in Germany are exposed to a variety of opportunities and risks. Some of the opportunities they face emerge from the rapid pace of technological development and the resulting business potential in artificial intelligence, big data analytics, internet of things and cloud technologies. These technologies offer their customers a vast amount of opportunities to innovate their business models and design their digital transformation to compete. IT infrastructure vendors can benefit from associated investments. However, these developments also entail certain business risks for vendors, such as those arising from the availability of innovative public cloud offerings, which can replace commoditised IT infrastructure. As a result, IT Infrastructure vendors experience significant changes in customer (purchasing) behaviour, which threatens their business success. Some of these changes are of a disruptive nature and affect both the manufacturers and also their indirect sales partners in the IT infrastructure sales ecosystem. Based on a Grounded Theory Methodology (GTM) research approach, this study has aimed to improve the understanding of these market dynamics and to provide a transformation framework that enables vendors and their partners to adapt to the changes. Data collection was carried out by conducting twenty-four semi-structured interviews with business professionals who reported on their long-term experiences and observations in this regard. The study analysed which relevant influencing factors have to be considered and how the affected sales ecosystems are structurally changing. As the findings of the study indicate, successful IT infrastructure sales ecosystem transformations depend on a variety of influencing factors. From a customer perspective, these factors relate to the necessity of a modified vendor sales differentiation strategy, providing added value to clients during digital business transformation. Corresponding activities build on the prior development of the skills of the vendors' sales teams. Furthermore, the study underlines the relevance of developing and expanding the sales partner landscape to provide customers with a scalable ecosystem with all digitalisation-relevant core competencies during the increasingly demanding sales process. The study also revealed an increased need to particularly take into account individual sales employee needs and concerns during transformation efforts and to promote improved procedural and organisational agility. For each of these aspects, the study presents and discusses a variety of adequate action strategies. Compared to the existing literature, the findings particularly suggest a different way of thinking during transformation that takes into account the relevance of ambidexterity, trust and empowerment of employees and partners to ensure transformation success. As a further contribution to both theory and practice the study provides the so-called “A.C.T.I.V.A.T.E.” model for managing transformational change, which integrates the identified influencing factors and provides concrete strategies to handle them. For this purpose, the framework allows the assessment of the individual maturity level of sales ecosystems and suggests concrete recommendations to develop them further. This approach enables vendors and their partners to exploit and explore both existing and new market opportunities and to mitigate transformation risks to the same extent

Architecture Design Options for Federated Data Spaces

The massive growth of data and the increasing potential of data analytics in industrial production fuel the emergence of data spaces and corresponding platforms that realize data ecosystems and enable data-driven sustainability applications. To leverage their benefits of demand-driven and scalable data integration, the stakeholders of emerging data space initiatives must make informed decisions about their data space support platforms (DSSPs). This study proposes a conceptual framework based on federated architectures and by considering existing endeavors of data infrastructures. Based on existing literature about data ecosystem resources and an explorative single case study of an industrial data space with sustainability-focused applications, we elaborate on the key design options of data, services, and computing infrastructures. The resulting conceptual framework guides design decisions for DSSPs. The framework captures not only the resources involved but also the operational concepts of federated services and shared services to introduce governance mechanisms and sustainability policies

Enforcing public data archiving policies in academic publishing: A study of ecology journals

To improve the quality and efficiency of research, groups within the scientific community seek to exploit the value of data sharing. Funders, institutions, and specialist organizations are developing and implementing strategies to encourage or mandate data sharing within and across disciplines, with varying degrees of success. Academic journals in ecology and evolution have adopted several types of public data archiving policies requiring authors to make data underlying scholarly manuscripts freely available. Yet anecdotes from the community and studies evaluating data availability suggest that these policies have not obtained the desired effects, both in terms of quantity and quality of available datasets. We conducted a qualitative, interview-based study with journal editorial staff and other stakeholders in the academic publishing process to examine how journals enforce data archiving policies. We specifically sought to establish who editors and other stakeholders perceive as responsible for ensuring data completeness and quality in the peer review process. Our analysis revealed little consensus with regard to how data archiving policies should be enforced and who should hold authors accountable for dataset submissions. Themes in interviewee responses included hopefulness that reviewers would take the initiative to review datasets and trust in authors to ensure the completeness and quality of their datasets. We highlight problematic aspects of these thematic responses and offer potential starting points for improvement of the public data archiving process.Comment: 35 pages, 1 figure, 1 tabl
