From ocean sprawl to blue-green infrastructure:A UK perspective on an issue of global significance
Artificial structures are proliferating in the marine environment, resulting in âocean sprawlâ. In light of the potential environmental impacts of this, such as habitat loss and alteration, it is becoming increasingly important to incorporate ecologically-sensitive design into artificial marine structures. The principles of eco-engineering and green infrastructure are embedded in urban planning practice for terrestrial and freshwater development projects. In marine planning, however, eco-engineering of blue-green infrastructure remains an emerging concept. This note provides a UK perspective on the progress towards uptake of eco-engineering approaches for enhancing biodiversity on artificial marine structures. We emphasise that, despite a clear âpolicy pullâ to incorporate biodiversity enhancements in marine structures, a range of proof-of-concept evidence that it is possible to achieve, and strong cross-sectoral stakeholder support, there are still few examples of truly and purposefullydesigned blue-green artificial structures in the UK. We discuss the barriers that remain and propose a strategy towards effective implementation. Our strategy outlines a step-wise approach to: (1) strengthening the evidence base for what enhancements can be achieved in different scenarios; (2) improving clarity on the predicted benefits and associated costs of enhancements; (3) packaging the evidence in a useful form to support planning and decision-making; and (4) encouraging implementation as routine practice. Given that ocean sprawl is a growing problem globally, the perspective presented here provides valuable insight and lessons for other nations at their various states of progress towards this same goal
Good gamers, good managers? A proof-of-concept study with Sid Meierâs Civilization
Human resource professionals increasingly enhance their assessment tools with game elementsâa process typically referred to as âgamificationââto make them more interesting and engaging for candidates, and they design and use âserious gamesâ that can support skill assessment and development. However, commercial, off-the-shelf video games are not or are only rarely used to screen or test candidates, even though there is increasing evidence that they are indicative of various skills that are professionally valuable. Using the strategy game Civilization, this proof-of-concept study explores if strategy video games are indicative of managerial skills and, if so, of what managerial skills. Under controlled laboratory conditions, we asked forty business students to play the Civilization game and to participate in a series of assessment exercises. We find that students who had high scores in the game had better skills related to problem-solving and organizing and planning than the students who had low scores. In addition, a preliminary analysis of in-game data, including playersâ interactions and chat messages, suggests that strategy games such as Civilization may be used for more precise and holistic âstealth assessments,â including personality assessments
Improving Studentsâ Creativity In The Proving The Validity Of Arguments Through Learning Strategy âWhatâs Another Wayâ
The purpose of this study was to describe the enhancing creativity of students in proving the validity of arguments through learning strategy "what's another way". This research was an action research with qualitative descriptive approach. The subjects were students of mathematics education UNIROW Tuban. The study was conducted in three cycles, Cycle I: Proof of Validity Arguments Directly, Cycle II: Proof of Validity Arguments Indirectly, and Cycle III: Validity Evidence Arguments Containing Kuantor. This research results in the following: In general, the learning strategy "what's another way" to improve the creativity of students in proving the validity of the argument. The main difficulty in proving the validity of the argument is as follows: a) the use of evidentiary rules of argument, and b) the idea of proof plan.
Key Words: creativity, proving, argument, validity, and âwhatâs another way
The Adapting city. Resilience through water design in Rotterdam
The Netherlands is a fragile and vulnerable land; spatial
planning is very important, just as important is the
resilience of the system and its adaptation to climate
change. Rotterdam is a delta city and, in a period of
heavy climate change, it will experiment more extreme
weather conditions, such as heavier rainstorms, longer
periods of drought and more heat waves, as well as
higher water levels in the river Meuse; so is important to
know that it is a deep vulnerable city and need right
strategies to overcome the problem and to be adapted to
conseguences of climate change. The results presented
in these manuscript were developed through some
academic course at TUDelft; the main aim is to arrive at
shared ambitions for climate proof urban development
and to make specific concrete agreements about this
defining a strategy able to enforce urban beauty and
absorb excess rainwater and improve urban resilience
through the implementation of some adaptive measures
linking this strategy to the whole urban governante of
the city. There is the need to implement a conscious and
smart urban governance and to undertake urban
awareness actions that aim at the awareness of the
communities, which becomes an active part in promoting
urban resilience policies and in creating the sustainable
city. The strategy is characterized by some main
innovation that could be recreated in other countries,
such as the inclusion of resilienceâs theme in all levels of
government and in all urban planning instruments and in
spatial and strategic development policies; the deep
cooperation between all stakeholders and public
administrations; and the role of urban design that is able
to create a waterproof city, enhancing the quality of
public space
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
Searching for a Solution to Program Verification=Equation Solving in CCS
International audienceUnder non-exponential discounting, we develop a dynamic theory for stopping problems in continuous time. Our framework covers discount functions that induce decreasing impatience. Due to the inherent time inconsistency, we look for equilibrium stopping policies, formulated as fixed points of an operator. Under appropriate conditions, fixed-point iterations converge to equilibrium stopping policies. This iterative approach corresponds to the hierarchy of strategic reasoning in game theory and provides âagent-specificâ results: it assigns one specific equilibrium stopping policy to each agent according to her initial behavior. In particular, it leads to a precise mathematical connection between the naive behavior and the sophisticated one. Our theory is illustrated in a real options model
