    This is the author accepted manuscript. The final version is available from Springer Verlag via the DOI in this record.Support for the proposition that the Quiet Eye (QE) duration reflects a period of response programming (including task parameterisation) has come from research showing that an increase in task difficulty is associated with increases in QE duration. Here, we build on previous research by manipulating three elements of task difficulty that correspond with different parameters of golf-putting performance; force production, impact quality and target line. Longer QE durations were found for more complex iterations of the task and furthermore, more sensitive analyses of the QE duration suggest that the early QE proportion (prior to movement initiation) is closely related to force production and impact quality. However, these increases in QE do not seem functional in terms of supporting improved performance. Further research is needed to explore QE's relationship with performance under conditions of increased difficulty

    How Dutch Institutions Enhance the Adaptive Capacity of Society

    This report examines the adaptive capacity of the institutional framework of the Netherlands to cope with the impacts of climate change. Historically, institutions have evolved incrementally to deal with existing social problems. They provide norms and rules for collective action and create continuity rather than change. However, the nature of societal problems is changing as a result of the processes of globalization and development. With the progress made in the natural sciences, we are able to predict in advance, to a certain extent, the potential environmental impacts of various human actions on society, for example, climate change. This raises some key questions: Are our institutions capable of dealing with this new knowledge about future impacts and, more importantly, with the impacts themselves? Are our institutions capable of dealing with the inherent uncertainty of the predictions

    © 2015 by the authors, licensee MDPI, Basel, Switzerland. The waste hierarchy currently dominates waste management planning in Australia. It is effective in helping planners consider options from waste avoidance or "reduction" through to providing infrastructure for landfill or other "disposal". However, it is inadequate for guiding context-specific decisions regarding sustainable waste management and resource recovery, including the ability for stakeholders to compare a range of options on an equal footing whilst considering their various sustainability impacts and trade-offs. This paper outlines the potential use of Integrated Resource Planning (IRP) as a decision-making approach for the urban waste sector, illustrated using an Australian case study. IRP is well established in both the water and energy sectors in Australia and internationally. It has been used in long-term planning enabling decision-makers to consider the potential to reduce resource use through efficiency alongside options for new infrastructure. Its use in the waste sector could address a number of the current limitations experienced by providing a broader context-sensitive, adaptive, and stakeholder focused approach to planning not present in the waste hierarchy and commonly used cost benefit analysis. For both efficiency and new infrastructure options IRP could be useful in assisting governments to make decisions that are consistent with agreed objectives while addressing costs of alternative options and uncertainty regarding their environmental and social impacts. This paper highlights various international waste planning approaches, differences between the sectors where IRP has been used and gives a worked example of how IRP could be applied in the Australian urban waste sector

    De projectgroep IC12 van Klimaat voor Ruimte onderzoekt de adaptiviteit van instituties in relatie tot klimaatverandering. Op basis van theorie is een adaptatiewiel voor de adaptiviteit van instituties ontworpen. We willen graag weten of deze herkend wordt door praktijkdenkers en bruikbaar wordt gevonden, waarbij we ons richten op de adaptiviteit van instituties in de volgende sectoren: natuur, landbouw, ruimtelijke ordening en water

    Institutions for adaptation: do institutions allow society to adapt to the impacts of climate change?

    Get PDF
    Historisch gezien hebben instituties (formele en informele sociale regels en interactiepatronen) zich altijd ontwikkeld als reactie op sociale problemen, waaronder milieuproblemen. De laatste decennia worden gekenmerkt door toenemende economische ontwikkeling en globalisering, waardoor sociale problemen zich sneller ontwikkelen en onze kennis over deze problemen toeneemt. Belangrijke vraag is: in hoeverre maken instituties een tijdige en effectieve reactie vanuit de samenleving op de gevolgen van klimaatverandering mogelijk? Eerst is het Adaptatiewiel ontwikkeld als een methode om instituties te beoordelen op de mate waarin zij aanpassingen vanuit de samenlevingen bevorderen of belemmeren. Darmee is vervolgens de officiële Nederlandse institutionele context geëvalueerd in vier beleidssectoren (natuur, landbouw, water en ruimtelijke ordening). Ook is het Adaptatiewiel toegepast in vier case studies (Individuele Verantwoordelijkheid, Waterveiligheid, Bouwen in Laaggelegen Gebieden en Waddenzee

    How to assess the adaptive capacity of legislation and policies

    Abstract: Intuitively it is clear that institutions can both enhance and hamper the adaptive capacity of a society. But what characteristics make an institution more or less helpful for development and implementation of adaptation strategies? Based on the literature, we developed an analytical framework to assess the adaptive capacity of institutions. The Adaptive Capacity Wheel consists of six dimensions: variety, learning, autonomous ability to change, leadership, legitimacy and resources. The six dimensions were operationalised into 22 criteria and were applied to formal institutions in a content analysis. We conclude that sometimes dimensions and criteria seem to contradict each other, which is not surprising, because this reflects existing paradoxes in the governance of society. We would like to discuss the analytical instrument and its possible uses with the audience of the Amsterdam Conference

    Anthropogenic Heat Flux Estimation from Space: Results of the first phase of the URBANFLUXES Project

    Get PDF
    H2020-Space project URBANFLUXES (URBan ANthrpogenic heat FLUX from Earth observation Satellites) investigates the potential of Copernicus Sentinels to retrieve anthropogenic heat flux, as a key component of the Urban Energy Budget (UEB). URBANFLUXES advances the current knowledge of the impacts of UEB fluxes on urban heat island and consequently on energy consumption in cities. This will lead to the development of tools and strategies to mitigate these effects, improving thermal comfort and energy efficiency. In URBANFLUXES, the anthropogenic heat flux is estimated as a residual of UEB. Therefore, the rest UEB components, namely, the net all-wave radiation, the net change in heat storage and the turbulent sensible and latent heat fluxes are independently estimated from Earth Observation (EO), whereas the advection term is included in the error of the anthropogenic heat flux estimation from the UEB closure. The project exploits Sentinels observations, which provide improved data quality, coverage and revisit times and increase the value of EO data for scientific work and future emerging applications. These observations can reveal novel scientific insights for the detection and monitoring of the spatial distribution of the urban energy budget fluxes in cities, thereby generating new EO opportunities. URBANFLUXES thus exploits the European capacity for space-borne observations to enable the development of operational services in the field of urban environmental monitoring and energy efficiency in cities.

    There is currently little data on the longer term efficacy and safety of balloon kyphoplasty (BKP) in patients with metastatic vertebral compression fractures (VCFs). To prospectively assess the long-term efficacy and safety of BKP in treating thoracic and lumbar spinal metastatic fractures that result in pain or instability. Sixty-five patients (37 men, mean age: 66 years) underwent 99 BKP procedures. Patient-related outcomes of pain visual analogue scale (VAS) and Oswestry Disability Index were assessed pre- and post-operatively and after 3, 6, 12 and 24 months. Correction of vertebral height and kyphotic deformity were assessed by radiographic measurements. Mean pain VAS and Oswestry Disability Index significantly improved from pre- to post-treatment (P < 0.0001), this improvement being sustained up to 24-month follow up. A gain in height restoration and a reduction of the post-operative kyphotic angle were seen post-operatively and at 3 months although these radiographic outcomes returned to pre-operative levels at 12 months. BKP was associated with a rate of cement leakage and incidence vertebral fracture of 12 and 8%, respectively. No symptomatic cement leaks or serious adverse events were seen during the 24 months of follow up. BKP is a minimally invasive procedure that provides immediate and long-term pain relief and improvement in functional ability in selected patients with metastatic VCFs. The procedure appears to have good long-term safety
