extract from five examples in Switzerland

Based on the suggestion in the literature that conservation objectives should be linked with local development objectives to successfully realise community- based conservation, and little available knowledge about corresponding projects, we set off to deepen our comprehension about how these projects work in the field. We investigate cases that were from the outset framed as having two objectives; these cases are combined projects of flood prevention and river restoration in Switzerland. Our aim was to better understand the role of the multi-level governance setting for the success of these projects The corresponding objective was to identify, what role legal regulations, administrative conditions, available financial resources and other factors from different levels (confederation, canton and municipalities) play for the realisation of these projects. We investigated these projects by conducting personal interviews with project leaders and stakeholders that participated in five collaborative planning processes; for each case we interviewed at least five participants. We find that the difficulty to ‘gain space for the river’ was the main stumbling block for the planning and implementation of these multipurpose projects. Federal and cantonal regulations and requirements clearly shaped these projects and the corresponding institutions exercised the possible control based upon financial resources. Existing regulations turned out to be flexible instruments and adaptable, when they had been hindering emerging and desirable practices in river engineering. These regulations also permitted considerable autonomy to the local actors to arrange and negotiate their concerns in the projects. This autonomy made it possible to harness the ‘local social ingredients’ we identified as crucial to make these projects work, which are convincing actors that make a case for conservation issues, existing trust within the community –more specifically— to have good reasons to trust that nobody would be disadvantaged clearly more than other, and the willingness of local actors to invest patience and time to avoid conflict and to work on agreeable solutions.Draf

Approximate Approximation on a Quantum Annealer

Many problems of industrial interest are NP-complete, and quickly exhaust resources of computational devices with increasing input sizes. Quantum annealers (QA) are physical devices that aim at this class of problems by exploiting quantum mechanical properties of nature. However, they compete with efficient heuristics and probabilistic or randomised algorithms on classical machines that allow for finding approximate solutions to large NP-complete problems. While first implementations of QA have become commercially available, their practical benefits are far from fully explored. To the best of our knowledge, approximation techniques have not yet received substantial attention. In this paper, we explore how problems' approximate versions of varying degree can be systematically constructed for quantum annealer programs, and how this influences result quality or the handling of larger problem instances on given set of qubits. We illustrate various approximation techniques on both, simulations and real QA hardware, on different seminal problems, and interpret the results to contribute towards a better understanding of the real-world power and limitations of current-state and future quantum computing.Comment: Proceedings of the 17th ACM International Conference on Computing Frontiers (CF 2020

Environmental Regulations of Land-use and Public Compensation: Principles with Swiss and Australian Examples

This paper discusses regulation of rural land-use and compensation, both of which appear to have become more common but also more disputed. The implications of contemporary theories in relation to this matter are examined. Coverage includes the applicability of new welfare economics, the relevance of the neoclassical theory of politics, and the implications of contemporary theories of social conflict resolution and communication. Examining case studies of Swiss and Australian regulation of the use of rural properties and the ensuing conflicts, it is found that many decisions reflect a mixture of these elements. Rarely, if ever, are social decisions in this area made solely on the basis of welfare economics, for instance social cost-benefit analysis. Only some aspects of such decisions can be explained by the neoclassical theory of politics, and only ex post. Theories of social conflict resolution suggest why approaches of discourse and participation may resolve conflicts on regulation and compensation and in which way. These theories and their practical application seem to gain in importance as contest against decisions in a sovereign capacity increases. The high complexity of most conflicts on regulation and compensation cannot be tackled with narrow economic theories. Moreover, the Swiss and Australian examples show that such approaches of conflict resolution may rather favour environmental standards

Transformative enterprises: Characteristics and a definition

This paper contributes to an emerging discussion about transformative enterprises, which are increasingly seen as change agents in sustainability transformations. Some schol-ars have hitherto described them as pioneering enterprises that strive for fundamental changes towards sustainability at different scales. Economic geography has, however, so far glossed over a micro-perspective on such enterprises. In this paper, we define transformative enterprises in detail by systematically identifying and elaborating their characteris-tics and actions. We ask: What operationalizable character-istics that refer to transformative enterprises are discussed in the literature? How can we define transformative enterprises?Starting from a comprehensive literature review, we iden-tify nine key dimensions of transformative enterprises that we specify with a set of indicators, and we then synthesize our finding with a definition. With this contribution, we further develop the concept of transformative enterprise in economic geography and show how it complements current conceptualizations of firm-level agency and system-level agency

Reactive arthritis in tuberculosis : a case of Poncet's disease

Reactive arthritis and erythema are uncommon presentations of tuberculosis (TB). Reactive arthritis in tuberculosis (TB) is known as Poncet's disease, a rare aseptic form of arthritis observed in patients with active TB. We report a case of Poncet's disease in a 20-year old man whose reactive arthritis overshadowed other clinical symptoms of TB resulting in delayed diagnosis and treatment. Although a conclusive diagnosis of Poncet's disease is not possible, reactive immunologic reactions such as reactive arthritis and erythema nodosum even without respiratory symptoms should raise suspicion on possible TB. Thus, taking a thorough medical history as well as performing relevant examinations and investigations for possible TB will help expedite the diagnostic process
