  1. Strategies to Overcome Collaborative Innovation Barriers: The Role of Training to Foster Skills to Navigate Quadruple Helix Innovations.Luisa Barbosa-Gomez & Vincent Blok - 2023 - Journal of the Knowledge Economy.
    Quadruple Helix Collaborations (QHCs) is a cooperation model in which industry, government, academia, and the public interact to innovate. This paper analyses the impact of a training intervention to provide specific knowledge, skills, and attitudes to deal with barriers commonly found in the progress of QHCs. We designed, implemented, and evaluated three training programs in Austrian, Colombian, Danish, and Spanish institutions. We analysed trainees’ (n = 66) and trainers’ (n = 9) perceptions to identify the competencies acquired with the (...)

  2. A Processual Approach to friction in Quadruple Helix Collaborations.E. Popa, Vincent Blok & R. Wesselink - 2020 - Science and Public Policy 6 (47):876-889.
    R&D collaborations between industry, government, civil society, and research (also known as ‘quadruple helix collaborations’ (QHCs)) have recently gained attention from R&D theorists and practitioners. In aiming to come to grips with their complexity, past models have generally taken a stakeholder-analytical approach based on stakeholder types. Yet stakeholder types are difficult to operationalise. We therefore argue that a processual model is more suited for studying the interaction in QHCs because it eschews matters of titles and identities. We develop such (...)

  4. Launching of Davydov solitons in protein α-helix spines.Danko D. Georgiev & James F. Glazebrook - 2020 - Physica E: Low-Dimensional Systems and Nanostructures 124:114332.
    Biological order provided by α-helical secondary protein structures is an important resource exploitable by living organisms for increasing the efficiency of energy transport. In particular, self-trapping of amide I energy quanta by the induced phonon deformation of the hydrogen-bonded lattice of peptide groups is capable of generating either pinned or moving solitary waves following the Davydov quasiparticle/soliton model. The effect of applied in-phase Gaussian pulses of amide I energy, however, was found to be strongly dependent on the site of application. (...)

  5. Thermal stability of solitons in protein α-helices.Danko D. Georgiev & James F. Glazebrook - 2022 - Chaos, Solitons and Fractals 155:111644.
    Protein α-helices provide an ordered biological environment that is conducive to soliton-assisted energy transport. The nonlinear interaction between amide I excitons and phonon deformations induced in the hydrogen-bonded lattice of peptide groups leads to self-trapping of the amide I energy, thereby creating a localized quasiparticle (soliton) that persists at zero temperature. The presence of thermal noise, however, could destabilize the protein soliton and dissipate its energy within a finite lifetime. In this work, we have computationally solved the system of stochastic (...)

  6. Quantum tunneling of three-spine solitons through excentric barriers.Danko D. Georgiev & James F. Glazebrook - 2022 - Physics Letters A 448:128319.
    Macromolecular protein complexes catalyze essential physiological processes that sustain life. Various interactions between protein subunits could increase the effective mass of certain peptide groups, thereby compartmentalizing protein α-helices. Here, we study the differential effects of applied massive barriers upon the soliton-assisted energy transport within proteins. We demonstrate that excentric barriers, localized onto a single spine in the protein α-helix, reflect or trap three-spine solitons as effectively as concentric barriers with comparable total mass. Furthermore, wider protein solitons, whose energy is (...)

  7. In the chaos of today's society: The dynamics of collapse as another shift in the quantum anthropology of Heidi Ann Russell.Radek Trnka - 2015 - Prague: Togga.
    The presented study introduces a new theoretical model of collapse for social, cultural, or political systems. Based on the current form of quantum anthropology conceptualized by Heidi Ann Russell, further development of this field is provided. The new theoretical model is called the spiral model of collapses, and is suggested to provide an analytical framework for collapses in social, cultural, and political systems. The main conclusions of this study are: 1) The individual crises in the period before a collapse of (...)

  8. How could Vygotsky inform an approach to scientific representations?Dimitris Kilakos - 2016 - Epistemology and Philosophy of Science 47 (1):140-152.
    In the quest for a new social turn in philosophy of science, exploring the prospects of a Vygotskian perspective could be of significant interest, especially due to his emphasis on the role of culture and socialisation in the development of cognitive functions. However, a philosophical reassessment of Vygotsky's ideas in general has yet to be done. As a step towards this direction, I attempt to elaborate an approach on scientific representations by drawing inspirations from Vygotsky. Specifically, I work upon Vygotsky’s (...)

  9. The new (liberal) eugenics.Nicolae Sfetcu - manuscript
    Despite the Nazi horrors, in 1953 the new eugenics was founded, when Watson and Crick postulated the double helix of DNA as the basis of chemical heredity. In 1961, scientists have deciphered the genetic code of DNA, laying the groundwork for code manipulation and the potential building of new life forms. After thirty years from the discovery of the DNA structure, the experimenters began to carry out the first clinical studies of human somatic cell therapy. The practice of prenatal (...)

  11. Review of The Inflationary Universe by Alan Guth (1997).Michael Starks - 2016 - In Suicidal Utopian Delusions in the 21st Century: Philosophy, Human Nature and the Collapse of Civilization-- Articles and Reviews 2006-2017 2nd Edition Feb 2018. Las Vegas, USA: Reality Press. pp. 615-618.
    This is one of the best popular cosmology books ever written and Guth is now (2016) a top physics Professor at MIT. He tells the extremely complex story of inflation and related areas of particle physics in such an absorbing style that it reads like a detective novel-in fact, it is a detective novel-how he and others found out how the universe started! The interweaving of his personal story and that of many colleagues along with their photos and many wonderfully (...)

  14. From blended learning to learning onlife : ICTs, time and access in higher education.Anders Norberg - unknown
    Information and Communication Technologies, ICTs, has now for decades being increasingly taken into use for higher education, enabling distance learning, e-learning and online learning, mainly in parallel to mainstream educational practise. The concept Blended learning (BL) aims at the integration of ICTs with these existing educational practices. The term is frequently used, but there is no agreed-upon definition. The general aim of this dissertation is to identify new possible perspectives on ICTs and access to higher education, for negotiating the dichotomy (...)

  15. Science Transformed?: Debating Claims of an Epochal Break.Alfred Nordmann, Hans Radder & Gregor Schiemann (eds.) - 2011 - University of Pittsburgh Press.
    Advancements in computing, instrumentation, robotics, digital imaging, and simulation modeling have changed science into a technology-driven institution. Government, industry, and society increasingly exert their influence over science, raising questions of values and objectivity. These and other profound changes have led many to speculate that we are in the midst of an epochal break in scientific history. -/- This edited volume presents an in-depth examination of these issues from philosophical, historical, social, and cultural perspectives. It offers arguments both for and against (...)

  17. An Epoch-Making Change in the Development of Science? A Critique of the “Epochal-Break-Thesis”.Gregor Schiemann - 2011 - In M. Carrier & A. Nordmann (eds.), Science in the Context of Application. Springer. pp. 431--453.
    In recent decades, several authors have claimed that an epoch-making change in the development of science is taking place. A closer examination of this claim shows that these authors take different – and problematic – concepts of an epochal break as their points of departure. In order to facilitate an evaluation of the current development of science, I would like to propose a concept of an epochal change according to which it is not necessarily a discontinuous process that typically begins (...)

  18. Quantum transport and utilization of free energy in protein α-helices.Danko D. Georgiev & James F. Glazebrook - 2020 - Advances in Quantum Chemistry 82:253-300.
    The essential biological processes that sustain life are catalyzed by protein nano-engines, which maintain living systems in far-from-equilibrium ordered states. To investigate energetic processes in proteins, we have analyzed the system of generalized Davydov equations that govern the quantum dynamics of multiple amide I exciton quanta propagating along the hydrogen-bonded peptide groups in α-helices. Computational simulations have confirmed the generation of moving Davydov solitons by applied pulses of amide I energy for protein α-helices of varying length. The stability and mobility (...)

  19. Strukturwandel der Wissenschaft.Gregor Schiemann, Alfred Nordmann & Hans Radder (eds.) - 2014
    Mit Robotik, Digitalisierung, softwaregesteuerten Präzisionsinstrumenten und hochkomplexen Simulationsverfahren wird heute Technik zur treibenden Kraft der wissenschaftlichen Forschungspraxis. Gleichzeitig sieht sich die universitäre Forschung wachsenden gesellschaftlichen Einflüssen ausgesetzt und nähert sich selbst immer mehr der Industrieforschung an, woraus sich neue Fragen nach den Werten und der Objektivität der Wissenschaft ergeben. Derartig weitreichende Veränderungen haben zahlreiche Spekulationen darüber provoziert, ob sich in der Wissenschaftsgeschichte gegenwärtig ein Epochenbruch vollzieht. Dieser Sammelband setzt sich aus philosophischen, historischen und kulturwissenschaftlichen Perspektiven mit den Epochenbruchthesen auseinander, bestätigt (...)
