  1. Types of Uncertainty.Richard Bradley & Mareile Drechsler - 2014 - Erkenntnis 79 (6):1225-1248.
    We distinguish three qualitatively different types of uncertainty—ethical, option and state space uncertainty—that are distinct from state uncertainty, the empirical uncertainty that is typically measured by a probability function on states of the world. Ethical uncertainty arises if the agent cannot assign precise utilities to consequences. Option uncertainty arises when the agent does not know what precise consequence an act has at every state. Finally, state space uncertainty exists when the agent is unsure how to construct an exhaustive state space. (...)

    Axiomatizing Bounded Rationality: The Priority Heuristic.Mareile Drechsler, Konstantinos Katsikopoulos & Gerd Gigerenzer - 2014 - Theory and Decision 77 (2):183-196.
    This paper presents an axiomatic framework for the priority heuristic, a model of bounded rationality in Selten’s Bounded rationality: the adaptive toolbox, 2001) spirit of using empirical evidence on heuristics. The priority heuristic predicts actual human choices between risky gambles well. It implies violations of expected utility theory such as common consequence effects, common ratio effects, the fourfold pattern of risk taking and the reflection effect. We present an axiomatization of a parameterized version of the heuristic which generalizes the heuristic (...)

    Rationality, Decisions and Large Worlds.Mareile Drechsler - 2012 - Dissertation, London School of Economics
    Taking Savage's subjective expected utility theory as a starting point, this thesis distinguishes three types of uncertainty which are incompatible with Savage's theory for small worlds: ambiguity, option uncertainty and state space uncertainty. Under ambiguity agents cannot form a unique and additive probability function over the state space. Option uncertainty exists when agents cannot assign unique consequences to every state. Finally, state space uncertainty arises when the state space the agent constructs is not exhaustive, such that unforeseen contingencies can occur. (...)

    Currents in a Theory of Strong Interaction Based on a Fiber Bundle Geometry.W. Drechsler - 1977 - Foundations of Physics 7 (9-10):629-671.
    A fiber bundle constructed over spacetime is used as the basic underlying framework for a differential geometric description of extended hadrons. The bundle has a Cartan connection and possesses the de Sitter groupSO(4, 1) as structural group, operating as a group of motion in a locally defined space of constant curvature (the fiber) characterized by a radius of curvatureR≈10−13 cm related to the strong interactions. A hadronic matter field ω(x, ζ) is defined on the bundle space, withx the spacetime coordinate (...)

    Broken Weyl Invariance and the Origin of Mass.W. Drechsler & H. Tann - 1999 - Foundations of Physics 29 (7):1023-1064.
    A massless Weyl-invariant dynamics of a scalar, a Dirac spinor, and electromagnetic fields is formulated in a Weyl space, W4, allowing for conformal rescalings of the metric and of all fields with nontrivial Weyl weight together with the associated transformations of the Weyl vector fields κμ, representing the D(1) gauge fields, with D(1) denoting the dilatation group. To study the appearance of nonzero masses in the theory the Weyl symmetry is broken explicitly and the corresponding reduction of the Weyl space (...)

    Geometro-Stochastic Quantization of a Theory for Extended Elementary Objects.Wolfgang Drechsler & Eduard Prugovečki - 1991 - Foundations of Physics 21 (5):513-546.
    The geometro-stochastic quantization of a gauge theory based on the (4,1)-de Sitter group is presented. The theory contains an intrinsic elementary length parameter R of geometric origin taken to be of a size typical for hadron physics. Use is made of a soldered Hilbert bundle ℋ over curved spacetime carrying a phase space representation of SO(4, 1) with the Lorentz subgroup related to a vierbein formulation of gravitation. The typical fiber of ℋ is a resolution kernel Hilbert space ℋ $_{\bar (...)

    Politics and ‘the Digital’: From Singularity to Specificity.Julien Jeandesboz & Mareile Kaufmann - 2017 - European Journal of Social Theory 20 (3):309-328.
    The relationship between politics and the digital has largely been characterized as one of epochal change. The respective theories understand the digital as external to politics and society, as an autonomous driver for global, unilateral transformation. Rather than supporting such singular accounts of the relationship between politics and the digital, this article argues for its specificity: the digital is best examined in terms of folds within existing socio-technical configurations, and as an artefact with a set of affordances that are shaped (...)

    Modified Weyl Theory and Extended Elementary Objects.W. Drechsler - 1989 - Foundations of Physics 19 (12):1479-1497.
    To represent extension of objects in particle physics, a modified Weyl theory is used by gauging the curvature radius of the local fibers in a soldered bundle over space-time possessing a homogeneous space G/H of the (4, 1)-de Sitter group G as fiber. Objects with extension determined by a fundamental length parameter R0 appear as islands D(i) in space-time characterized by a geometry of the Cartan-Weyl type (i.e., involving torsion and modified Weyl degrees of freedom). Farther away from the domains (...)

    Peer Production and Desktop Manufacturing: The Case of the Helix_T Wind Turbine Project.Wolfgang Drechsler, Michail Fountouklis & Vasilis Kostakis - 2013 - Science, Technology, and Human Values 38 (6):773-800.
    Through the case of the Helix_T wind turbine project, this article sets out to argue two points: first, on a theoretical level, that Commons-based peer production, in conjunction with the emerging technological capabilities of three-dimensional printing, can also produce promising hardware, globally designed and locally produced. Second, the Commons-oriented wind turbine examined here is also meant to practically contribute to the quest for novel solutions to the timely problem of the need for renewable sources of energy, more in the sense (...)

    Seamlessness as Disenfranchisement: The Digital State of Pigs and How to Resist.Wolfgang Drechsler - 2020 - Acta Baltica Historiae Et Philosophiae Scientiarum 8 (2):38-53.
    If it is the tendency of technology, and especially of information and communication technology, particularly in the context of the smart city, not to empower the human person but rather to disenfranchise them by curtailing their capability to judge and choose, how can one counter this dynamic? Code, make, talk, and pray are suggested as possible modes of resistance.

    Classical Versus Quantum Gravity.Wolfgang Drechsler - 1993 - Foundations of Physics 23 (2):261-276.
    Is Einstein's metric theory of gravitation to be quantized to yield a complete and logically consistent picture of the geometry of the real world in the presence of quantized material sources? To answer this question, we give arguments that there is a consistent way to extend general relativity to small distances by incorporating further geometric quantities at the level of the connection into the theory and introducing corresponding field equations for their determination, allowing thereby the metric and the Levi-Civita connection (...)

    Marginalia in Medieval Western Scandinavian Law Manuscripts.Stefan Drechsler - 2020 - Das Mittelalter 25 (1):180-195.
    In the present chapter, the design of select margins of late medieval Old Norse manuscripts containing the Icelandic ‘Jónsbók’, ‘Kristinréttr Árna biskups’ and Norwegian ‘Landslǫg’ law codes is addressed. In particular, it discusses the size and fillings of margins in these codices and the relation to their modes of use by original clients and later owners. Although it is well-known that Scandinavian law manuscripts contain a large number of notes written by both original and later users, the particular use of (...)

    Should Law Keep Pace With Technology? Law as Katechon.Vasilis Kostakis & Wolfgang Drechsler - 2014 - Bulletin of Science, Technology and Society 34 (5-6):128-132.
    It is a commonly held belief that the law is unable to keep up with the fierce technological development and innovation that denote our times. The current essay attempts to show that this characteristic of the law should not necessarily be considered a disadvantage. Using the Biblical concept of the katechon, we argue that the law fulfills a katechontic function vis-a-vis technological progress. That is to say, its retarding effect might create positive spillovers that open spaces for debate, discussion, contestation, (...)

    Four Galore? The Overlap Between Mary Douglas’s Grid-Group Typology and Other Highly Cited Social Science Classifications.Marco Verweij, Petya Alexandrova, Henrik Jacobsen, Pauline Béziat, Diana Branduse, Yonca Dege, Jakob Hensing, James Hollway, Lea Kliem, Gabriela Ponce, Inga Reichelt & Mareile Wiegmann - 2020 - Sociological Theory 38 (3):263-294.
    Recently, neuroscientists have argued that elementary ways of organizing, perceiving, and justifying social relations lurk behind the diversity of social life. In developing grid-group typology, anthropologist Mary Douglas proposed such universal forms. If these are universal, then we could expect other widely cited classifications to overlap with grid-group typology. We tested this expectation by examining to which extent the elements of Douglas’s typology overlap with those of 39 highly influential classifications proposed since 1970. We established overlap by calculating the interrater (...)

    Mass Generation by Weyl Symmetry Breaking.Wolfgang Drechsler - 1999 - Foundations of Physics 29 (9):1327-1369.
    A massless electroweak theory for leptons is formulated in a Weyl space, W4, yielding a Weyl invariant dynamics of a scalar field φ, chiral Dirac fermion fields ψL and ψR, and the gauge fields κμ, Aμ, Zμ, Wμ, and Wμ †, allowing for conformal rescalings of the metric gμν and all fields with nonvanishing Weyl weight together with the corresponding transformations of the Weyl vector fields, κμ, representing the D(1) or dilatation gauge fields.

    Geometrie Und Materie — Ist Einsteins Vision Übertragbar Auf Die Elementarteilchenphysik?Wolfgang Drechsler - 1984 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 15 (1):1-21.
    Summary The philosophical implications associated with the choice of a particular geometry required for the formulation of a dynamics at subnuclear distances are discussed. A dualism between geometry and matter — the former identified with a fiber bundle of Cartan type raised over space-time, the latter represented by a generalized quantum mechanical wave function — is presented as a possible framework for the dynamics of strongly interacting particles at distances of 10-13 cm.

    Quantized Fiber Dynamics for Extended Elementary Objects Involving Gravitation.W. Drechsler - 1992 - Foundations of Physics 22 (8):1041-1077.
    The geometro-stochastic quantization of a gauge theory for extended objects based on the (4, 1)-de Sitter group is used for the description of quantized matter in interaction with gravitation. In this context a Hilbert bundle ℋ over curved space-time B is introduced, possessing the standard fiber ℋ $_{\bar \eta }^{(\rho )} $ , being a resolution kernel Hilbert space (with resolution generator $\tilde \eta $ and generalized coherent state basis) carrying a spin-zero phase space representation of G=SO(4, 1) belonging to (...)

    The Three Approaches to the Semiotics of Power.Sergey V. Sannikov - 2020 - Semiotica 2020 (236-237):47-53.
    The article focuses the possibility of elaboration of a cross-disciplinary methodological approach to formation of the semiotics of power. Four possible forms of relation of semiotic research to the problem of power are revealed upon the basis of Drechsler’s typology. The approaches of Mandoki and Siefkes to formation of the methodological basis of the semiotics of power are analyzed and compared. The author designates the perspective directions of a further research and formulates methodological prerequisites for realization of the specified (...)
