    Response to Pitkanen’s Solar System Model: Towards Gross-Pitaevskiian description of Solar System and Galaxies and more evidence of chiral superfluid vortices.Victor Christianto, Florentin Smarandache & Yunita Umniyati - manuscript
    In a new paper in recent issue of this journal (PSTJ), Prof. M. Pitkanen describes a solar system model inspired by spiral galaxies. While we appreciate his new approach, we find it lacks substantial discussion on the nature of vortices and chirality in galaxy. Therefore we submit a viewpoint that Gross-Pitaevskii model can be a more complete description of both solar system and also spiral galaxies, especially taking into account the nature of chirality and vortices in (...)

    The Measurement of Radial Velocities of Spiral Nebulae.Norriss Hetherington - 1971 - Isis 62:309-313.
    DURING THE SECOND DECADE of the twentieth century at least three different hypotheses involving the radial velocities of spiral nebulae appeared in astronomical journals, marking the introduction of a new field of study for astronomers. Willem de Sitter argued that a velocity-distance relation would exist if space were curved.' W. W. Campbell speculated on a possible link between radial velocities and evolutionary stages of nebulae.2 And V. M. Slipher announced his belief that the radial velocities of spiral nebulae (...)

    NGC 1300 (shown in figure 1) is a spiral galaxy 65 million light years from Earth.1 We have never been there, and (although I would love to be wrong about this) we will never go there; all we will ever know about NGC 1300 is what we can see of it from sixty-five million light years away, and what we can infer from our best physics. Fortunately, “what we can infer from our best physics” is actually quite a lot. (...)

    About Dark Energy and Dark Matter in a Three-Dimensional Quantum Vacuum Model.Davide Fiscaletti - 2016 - Foundations of Physics 46 (10):1307-1340.
    A model of a three-dimensional quantum vacuum based on Planck energy density as a universal property of a granular space is suggested. The possibility to provide an unifying explanation of dark matter and dark energy as phenomena linked with the fluctuations of the three-dimensional quantum vacuum is explored. The changes and fluctuations of the quantum vacuum energy density generate a curvature of space–time similar to the curvature produced by a “dark energy” density. The formation of large scale structures in the (...)

    A Conjecture on the Neutrality of Matter.Leonardo Campanelli - 2021 - Foundations of Physics 51 (3):1-11.
    Elaborating on an old conjecture by Blackett, we formulate a new conjecture about the neutrality of matter according to which any physical system possesses an active electric charge proportional to its mass. We discuss limits on the conjecture coming from existing laboratory experiments on the neutrality of matter and from the observation of the global surface electric field of the Earth. In a cosmological setting, we show that a cosmic rotation of the Universe is inevitable if our conjecture is true (...)

    Fundamental Pattern and Consciousness.Jerry Gin - 2016 - Cosmos and History 12 (2):99-113.
    In the new physics and in the new field of cosmometry, 1 it is the fundamental pattern that results in the motion from which all is created. Everything starts with the point of infinite potential. The tetrahedron at the point gives birth to the cuboctahedron ; its motion and structure result in the creation of the torus structure. The torus structure is self-referencing on a moment by moment basis since all must pass through the center. But isn't self-referencing the basis (...)

    The Spiral Structure of Marshall McLuhan’s Thinking.Izabella Pruska Oldenhof & Robert Logan - 2017 - Philosophies 2 (2):9.
    We examine the spiral structure of the thinking and the work of Marshall McLuhan, which we believe will provide a new way of viewing McLuhan’s work. In particular, we believe that the way he reversed figure and ground, reversed content and medium, reversed cause and effect, and the relationship he established between the content of a new medium and the older media it obsolesced all contain a spiral structure going back and forth in time. Finally, the time structure (...)

    Spiral as the fundamental graphic representation of the Periodic Law. Blocks of elements as the autonomic parts of the Periodic System.Naum S. Imyanitov - 2015 - Foundations of Chemistry 18 (2):153-173.
    The spiral form of the Periodic Law is proposed as its fundamental graphic representation. This idea is based on the fact that the spiral is the most appropriate form in description transitions from simple to complicated. The spiral is easily obtained from the linear succession of the elements when they are ranged by growing nuclear charge. The spiral can be simply transformed into many other graphic representations, including tables. This paper suggests the conception of the autonomy (...)

    Spirals of Spirituality: A Qualitative Study Exploring Dynamic Patterns of Spirituality in Turkish Organizations.Emine Sarigollu & Fahri Karakas - 2019 - Journal of Business Ethics 156 (3):799-821.
    This paper explores organizational spirituality, uncovers it as spiralling dynamics of both positive and negative potentialities, and proposes how leaders can shape these dynamics to improve the human conditions at the workplace. Based on case study of five Turkish organizations and drawing on the emerging discourse on spirituality in organizations literature, this study provides a deeper understanding of how dynamic patterns of spirituality operate in organizations. Insights from participant observation, organizational data, and semi-structured interviews yield three key themes of organizational (...)

    The Spiral of Responsibility and the Pressure to Conflict.Eric MacGilvray - 2020 - Critical Review: A Journal of Politics and Society 32 (1-3):145-163.
    ABSTRACT This essay calls attention to two blind spots in Power Without Knowledge. First, the book has little to say about the role that political institutions can play in promoting effective democratic governance. Drawing on the “mixed government” tradition, I argue that properly designed institutions can correct for the epistemic deficits that Friedman describes by creating what I call the “pressure to conflict.” Second and more importantly, the book has nothing to say about the role of responsible leadership in a (...)

    The Spiralling Economy: Connecting Marxian Theory with Ecological Economics.Crelis Rammelt - 2020 - Environmental Values 29 (4):417-442.
    The capitalist mode of production and consumption is caught in a double bind: its expansion destabilises natural systems and fails to curb social inequities, while slowdown destabilises the inner workings of the economic system itself. To better understand what is happening in this phase of instability, this article proposes a System Dynamics representation that combines elements of Georgescu-Roegen's Ecological Economics with Marxian theory. Specifically, it draws from a diagram recently developed by David Harvey to communicate Marx's political economy in its (...)

    Spiral dependence between theories and taxonomy1.Berent Enç - 1976 - Inquiry: An Interdisciplinary Journal of Philosophy 19 (1-4):41-71.
    This paper analyses the traditionally recognized dependence between observation statements and theories. The analysis proceeds by working out the interrelationship between classification systems and theoretical frameworks. Cuvier's and Darwin's theories are used as examples to illustrate this issue. The second part of the paper develops a model designed to give an account of the historical development of this interrelationship. It is argued that the interdependence is not circular and that it is an integral part of scientific research. It is suggested (...)

    The spiral template: The revolution in the evolution from simple to complex systems.Wayne Nahu Lanham - 2008 - World Futures 64 (1):60 – 71.
    Change is an inborn trait of all organisms at every level of existence. This article proposes that the evolution of all life follows a course as if bound by a guiding principle or template. Overcoming disorder and entropy through diversity, this template has the properties of a spiral force, which acts to maintain continuity during change and transitions, and operates at all levels, from the simplest of forms to the most complex. Drawing from Chaos Theory, biology, depth psychology, and (...)

    The galaxy of the non-Linnaean nomenclature.Alessandro Minelli - 2019 - History and Philosophy of the Life Sciences 41 (3):31.
    Contrary to the traditional claim that needs for unambiguous communication about animal and plant species are best served by a single set of names ruled by international Codes, I suggest that a more diversified system is required, especially to cope with problems emerging from aggregation of biodiversity data in large databases. Departures from Linnaean nomenclature are sometimes intentional, but there are also other, less obvious but widespread forms of not Code-compliant grey nomenclature. A first problem is due to the circumstance (...)

    Vicious Spirals in Corporate Governance: Mandatory Rules for Systemic (Re)Balancing?Michael Galanis - 2011 - Oxford Journal of Legal Studies 31 (2):327-363.
    Until recently, as market forces gradually prevailed over government intervention, the contractarian view had emerged as a preferred method of economic governance due to its attractiveness for business. Following the recent collapse of financial markets and the resulting recession, however, this structural form is now being called into question as the calls for more regulation and government intervention increase. In this context, this article revisits the law versus contract debate in the field of corporate law and governance. Following a theoretical (...)

    The Spiral Discovery Network as an Automated General-Purpose Optimization Tool.Adam B. Csapo - 2018 - Complexity 2018:1-8.
    The Spiral Discovery Method was originally proposed as a cognitive artifact for dealing with black-box models that are dependent on multiple inputs with nonlinear and/or multiplicative interaction effects. Besides directly helping to identify functional patterns in such systems, SDM also simplifies their control through its characteristic spiral structure. In this paper, a neural network-based formulation of SDM is proposed together with a set of automatic update rules that makes it suitable for both semiautomated and automated forms of optimization.

    A spiral model of musical decision-making.Daniel Bangert, Emery Schubert & Dorottya Fabian - 2014 - Frontiers in Psychology 5:79605.
    This paper describes a model of how musicians make decisions about performing notated music. The model builds on psychological theories of decision-making and was developed from empirical studies of Western art music performance that aimed to identify intuitive and deliberate processes of decision-making, a distinction consistent with dual-process theories of cognition. The model proposes that the proportion of intuitive (Type 1) and deliberate (Type 2) decision-making processes changes with increasing expertise and conceptualizes this change as movement along a continually narrowing (...)

    Death Spiral or Euthanasia? The Demise of Generous Group Health Insurance Coverage.Mark V. Pauly, Olivia S. Mitchell & Yuhui Zeng - 2007 - Inquiry: The Journal of Health Care Organization, Provision, and Financing 44 (4):412-427.
    Employers must determine the types of health care plans to offer and also set employee premiums for each plan provided. Depending on the structure of the employee share of premiums across different health insurance plans, the incentives to choose one plan over another are altered. If employees know premiums do not fully reflect the risk differences among workers, such pricing can give rise to a so-called “death spiral” due to adverse selection. This paper uses longitudinal information from a natural (...)

    The view that folk psychology is primarily mindreading beliefs and desires has come under challenge in recent years. I have argued that we also understand others in terms of individual properties such as personality traits and generalizations from past behavior, and in terms of group properties such as stereotypes and social norms (Andrews 2012). Others have also argued that propositional attitude attribution isn’t necessary for predicting others’ behavior, because this can be done in terms of taking Dennett’s Intentional Stance (Zawidzki (...)

    Galaxies of meaning: Semiotics in media theory.Anna Jaysane-Darr - 2010 - Semiotica 2010 (182):229-246.
    The article examines the use of semiotics in media theory, advancing a critique of Saussurian approaches to media and harnessing Peirce's sign theory as a way to analyze media, with reference to the sign “terrorist.” The tiered model of media representation based on Saussure's sign relation is found to under-theorize the materiality of the sign, the indeterminacy of meaning, the significance of the speaking subject, and the ideological and institutional forces that work on the sign. The interpretant in Peirce's model (...)

    The Dark Galaxy Hypothesis.Michael Weisberg, Melissa Jacquart, Barry Madore & Marja Seidel - 2018 - Philosophy of Science 85 (5):1204-1215.
    Gravitational interactions allowed astronomers to conclude that dark matter rings all luminous galaxies in gigantic halos, but this only accounts for a fraction of the total mass of dark matter believed to exist. Where is the rest? We hypothesize that some of it resides in dark galaxies, pure dark matter halos that either never possessed or have totally lost their baryonic matter. This article explores methodological challenges that arise because of the nature of observation in astrophysics and examines (...)

    The article defines the research field of a semiotically oriented philosophy of digital communication. It lays out its methodological perspective, pointing out how the fake has always been at the center of semiotic research. It traces the origin of deepfakes back to the conception of GANs, whose essential semiotic workings it expounds on. It enucleates the specificities of the digital fake, especially in the production of artificial faces. It reviews the deepfake phenomenon, enunciating its most recent statistics, prevalent areas of (...)

    The relational–linguistic spiral: A model of language for theology.Timothy J. Crutcher - 2002 - Heythrop Journal 43 (4):463–479.
    This article attempts to sketch out a view of language as a relational–linguistic spiral by discussing some implications of the thought of Ludwig Wittgenstein for language in general. Language is cast as a spiral which revolves around a center of ‘human relationality’ that anchors all our speech and concepts but which revolves in an ever–widening way into an arena of meaning we call language. Language creates linguistic space for experience and invites one into these new experiences. The borders (...)

    Big History provides a unique opportunity to consider the development of the Universe as a single process. Within Big History studies one can distinguish some common evolutionary laws and principles. However, it is very important to recognize that there are many more such integrating principles, laws, mecha-nisms and patterns of evolution at all its levels than it is usually supposed. In the meantime, we can find the common traits in development, functioning, and interaction of apparently rather different processes and phenomena (...)

    Dark Matter in Galaxies: Evidences and Challenges.Paolo Salucci - 2018 - Foundations of Physics 48 (10):1517-1537.
    The evidence of the phenomenon for which, in galaxies, the gravitating mass is distributed differently than the luminous mass, increases as new data become available. Furthermore, this discrepancy is well structured and it depends on the magnitude and the compactness of the galaxy and on the radius, in units of its luminous size \, where the measure is performed. For the disk systems with \ all this leads to an amazing scenario, revealed by the investigation of individual and coadded (...)
