Towards the Evolution of Novel Vertical-Axis Wind Turbines
Renewable and sustainable energy is one of the most important challenges
currently facing mankind. Wind has made an increasing contribution to the
world's energy supply mix, but still remains a long way from reaching its full
potential. In this paper, we investigate the use of artificial evolution to
design vertical-axis wind turbine prototypes that are physically instantiated
and evaluated under approximated wind tunnel conditions. An artificial neural
network is used as a surrogate model to assist learning and found to reduce the
number of fabrications required to reach a higher aerodynamic efficiency,
resulting in an important cost reduction. Unlike in other approaches, such as
computational fluid dynamics simulations, no mathematical formulations are used
and no model assumptions are made.Comment: 14 pages, 11 figure
Towards a systemic research methodology in agriculture: Rethinking the role of values in science
The recent drastic development of agriculture, together with the growing societal interest in agricultural practices and their consequences, pose a challenge to agricultural science. There is a need for rethinking the general methodology of agricultural research. This paper takes some steps towards developing a systemic research methodology that can meet this challenge – a general self-reflexive methodology that forms a basis for doing holistic or (with a better term) wholeness-oriented research and provides appropriate criteria of scientific quality.
From a philosophy of research perspective, science is seen as an interactive learning process with both a cognitive and a social communicative aspect. This means, first of all, that science plays a role in the world that it studies. A science that influences its own subject area, such as agricultural science, is named a systemic science. From this perspective, there is a need to reconsider the role of values in science. Science is not objective in the sense of being value-free. Values play, and ought to play, an important role in science – not only in form of constitutive values such as the norms of good science, but also in the form of contextual values that enter into the very process of science. This goes against the traditional criterion of objectivity. Therefore, reflexive objectivity is suggested as a new criterion for doing good science, along with the criterion of relevance. Reflexive objectivity implies that the communication of science must include the cognitive context, which comprises the societal, intentional, and observational context. In accordance with this, the learning process of systemic research is shown as a self-reflexive cycle that incorporates both an involved actor stance and a detached observer stance. The observer stance forms the basis for scientific communication.
To this point, a unitary view of science as a learning process is employed. A second important perspective for a systemic research methodology is the relation between the actual, different, and often quite separate kinds of science. Cross-disciplinary research is hampered by the idea that reductive science is more objective, and hence more scientific, than the less reductive sciences of complex subject areas – and by the opposite idea that reductive science is necessarily reductionistic. Taking reflexive objectivity as a demarcator of good science, an inclusive framework of science can be established. The framework does not take the established division between natural, social and human science as a primary distinction of science. The major distinction is made between the empirical and normative aspects of science, corresponding to two key cognitive interests. Two general methodological dimensions, the degree of reduction of the research world and the degree of involvement in the research world, are shown to span this framework. The framework can form a basis for transdisciplinary work by way of showing the relation between more and less reductive kinds of science and between more detached and more involved kinds of science and exposing the abilities and limitations attendant on these methodological differences
Governing in the Anthropocene: are there cyber-systemic antidotes to the malaise of modern governance?
The Anthropocene imposes new challenges for governments, demanding capabilities for dealing with complexity and uncertainty. In this paper we examine how effective governing of social-biophysical dynamics is constrained by current processes and systems of government. Framing choices and structural determinants combine to create governance deficits in multiple domains, particularly in relation to the governing of complex larger-scale social – biophysical systems. Attempts to build capability for governing ‘wicked problems’ are relevant to sustainability science and Anthropocene governance, but these have mostly failed to become institutionalised. Two cases studies are reported to elucidate how the systemic dynamics of governing operate and fail in relation to espoused purpose. In the UK attempts to enact ‘joined-up’ government’ during the years of New Labour government reveal systemic flaws and consistent praxis failures. From Australia we report on water governance reforms with implications for a wide range of complex policy issues. We conclude that innovations are needed to build capacity for governing the unfolding surprises and inherent uncertainties of the Anthropocene. These include institutionalising, or structural incorporation, of cyber-systemic thinking/practices that can also enhance empowerment and creativity that underpins sustainability science
Immersive and non immersive 3D virtual city: decision support tool for urban sustainability
Sustainable urban planning decisions must not only consider the physical structure of the urban development but the economic, social and environmental factors. Due to the prolonged times scales of major urban development projects the current and future impacts of any decision made must be fully understood. Many key project decisions are made early in the decision making process with decision makers later seeking agreement for proposals once the key decisions have already been made, leaving many stakeholders, especially the general public, feeling marginalised by the process. Many decision support tools have been developed to aid in the decision making process, however many of these are expert orientated, fail to fully address spatial and temporal issues and do not reflect the interconnectivity of the separate domains and their indicators. This paper outlines a platform that combines computer game techniques, modelling of economic, social and environmental indicators to provide an interface that presents a 3D interactive virtual city with sustainability information overlain. Creating a virtual 3D urban area using the latest video game techniques ensures: real-time rendering of the 3D graphics; exploitation of novel techniques of how complex multivariate data is presented to the user; immersion in the 3D urban development, via first person navigation, exploration and manipulation of the environment with consequences updated in real-time. The use of visualisation techniques begins to remove sustainability assessment’s reliance on the existing expert systems which are largely inaccessible to many of the stakeholder groups, especially the general public

Information Theory Perspective on Modelling Sustainability
Sustainability requires integrated models for the description of the co-evolving relationships between the economy, society and nature. The paper argues that information theory as a transdisciplinary approach can provide the basis for new theoretical and practical developments in the modeling of sustainability. The methodological problems of its present paradigms (cybernetic, epistemological and pragmatic) however are currently being challenged by the requirements of sustainability. There is a need for a new approach to modeling based on information theory taking into account the assumptions about the nature of information processes, i.e. that they are real, spontaneous and subject to the principle of information relevance. The new sustainability modeling also needs to include intelligence as an information category. A global green information system (GGIS) is a possible example for the application of these concepts
Towards the Co-evolution of Food Experience Search Spaces Based on the Design Weltanschauung Model in Food Marketing
Kamran, Q., Topp, S., & Henseler, J. (2021). Towards the Co-evolution of Food Experience Search Spaces Based on the Design Weltanschauung Model in Food Marketing. Cogent Business and Management, 8(1), 1-23. [1901643]. https://doi.org/10.1080/23311975.2021.1901643Contemporary socio-technological shifts within global societies indicate that the preferences and values of a converging, well-informed and digitally connected society have shifted towards a movement based on sustainability and healthy and environmentally friendly common values. The effect of artificial intelligence has changed the nature of marketing and communication between firms and markets. Food marketers need to adjust to this new situation and integrate proven interdisciplinary theoretical frameworks, as these approaches can be aligned to address this situation. Due to the limitations of traditional-marketing-theory, the field has not captured this gap by addressing emerging trends effectively. We address these new developments by introducing the design of the Weltanschauung model, which is based on marketing within the dimensions of designing a firm-consumer-relationship based on cocreation and coevolution in the design and meaning search spaces. We apply a model-based-management methodology by aligning the nature of rigorous theory building and relevant practice via the design science research.publishersversionpublishe

Managing knowledge in the context of sustainable construction
The 21st century has been a growing awareness of the importance of the sustainability agenda. Moreover for construction, it has become increasingly important as clients are pushing for a more sustainable product to complement their organisations’ own strategic plans. Sustainable development can be defined as development that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable construction is therefore seen as the application of sustainable practices to the activities of the construction sector. One of the key factors in making construction projects more sustainable is overcoming the obstacles of capturing and managing the knowledge required by project teams to effect such change. Managing this knowledge is key to the construction industry because of the unique characteristics of its projects, i.e. multi-disciplinary teams, dynamic participation of team members, heavy reliance on previous experiences/heuristics, the one-off nature of the projects, tight schedules, limited budget, etc. Initiatives within the industry and academic research are developing mechanisms and tools for managing knowledge in construction firms and projects. Such work has so far addressed the issues of capturing, storing, and transferring knowledge
