    Making complex decisions in uncertain times: experiences of Dutch GPs as gatekeepers regarding hospital referrals during COVID-19—a qualitative study.Anne B. Wichmann, Yvonne Engels, Jaap Schuurmans, Janneke Dujardin & Dieke Westerduin - 2021 - BMC Medical Ethics 22 (1):1-8.
    BackgroundGeneral practitioners often act as gatekeeper, authorizing patients’ access to hospital care. This gatekeeping role became even more important during the current COVID-19 crisis as uncertainties regarding COVID-19 made estimating the desirability of hospital referrals (for outpatient or inpatient hospitalization) complex, both for COVID and non-COVID suspected patients. This study explored Dutch general practitioners’ experiences and ethical dilemmas faced in decision making about hospital referrals in times of the COVID-19 pandemic.MethodsSemi-structured interviews with Dutch general practitioners working in the Netherlands were (...)

    Quantum Mechanics and Perspectivalism.Dennis Dieks - unknown
    Experimental evidence of the last decades has made the status of ``collapses of the wave function'' even more shaky than it already was on conceptual grounds: interference effects turn out to be detectable even when collapses are typically expected to occur. Non-collapse interpretations should consequently be taken seriously. In this paper we argue that such interpretations suggest a perspectivalism according to which quantum objects are not characterized by monadic properties, but by relations to other systems. Accordingly, physical systems may possess (...)

    The Modal Interpretation of Quantum Mechanics.Dennis Dieks & Pieter Vermaas - 1998 - Kluwer Academic Publishers.
    According to the modal interpretation, the standard mathematical framework of quantum mechanics specifies the physical magnitudes of a system, which have definite values. Probabilities are assigned to the possible values that these magnitudes may adopt. The interpretation is thus concerned with physical properties rather than with measurement results: it is a realistic interpretation. One of the notable achievements of this interpretation is that it dissolves the notorious measurement problem. The papers collected here, together with the introduction and concluding critical appraisal, (...)

    (1 other version)Identical Quantum Particles as Distinguishable Objects.Dennis Dieks & Andrea Lubberdink - 2020 - Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie 53 (3):1-16.
    According to classical physics particles are basic building blocks of the world. These classical particles are distinguishable objects, individuated by unique combinations of physical properties. By contrast, in quantum mechanics the received view is that particles of the same kind are physically indistinguishable from each other and lack identity. This doctrine rests on the quantum mechanical symmetrization postulates together with the “factorist” assumption that each single particle is represented in exactly one factor space of the tensor product Hilbert space of (...)

  5. Von Neumann’s impossibility proof: Mathematics in the service of rhetorics.Dennis Dieks - 2017 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 60:136-148.
    According to what has become a standard history of quantum mechanics, von Neumann in 1932 succeeded in convincing the physics community that he had proved that hidden variables were impossible as a matter of principle. Subsequently, leading proponents of the Copenhagen interpretation emphatically confirmed that von Neumann's proof showed the completeness of quantum mechanics. Then, the story continues, Bell in 1966 finally exposed the proof as seriously and obviously wrong; this rehabilitated hidden variables and made serious foundational research possible. It (...)

    Leadership moments: Understanding nurse clinician‐scientists' leadership as embedded sociohistorical practices.Dieke Martini, Mirko Noordegraaf, Lisette Schoonhoven & Pieterbas Lalleman - 2023 - Nursing Inquiry 30 (4):e12580.
    Nurse clinician‐scientists are increasingly expected to show leadership aimed at transforming healthcare. However, research on nurse clinician‐scientists' leadership (integrating researcher and practitioner roles) is scarce and hardly embedded in sociohistorical contexts. This study introduces leadership moments, that is, concrete events in practices that are perceived as acts of empowerment, in order to understand leadership in the daily work of newly appointed nurse clinician‐scientists. Following the learning history method we gathered data using multiple (qualitative) methods to get close to their daily (...)

  14. Reworking Nursing Expertise: Directors of Nursing's Tactics to (Re)Connect Knowledge and Power in Hospital Governance.Dieke Martini, Mirko Noordegraaf, Lisette Schoonhoven, Jet Spits, Pauline Van Bokhorst & Pieterbas Lalleman - 2025 - Nursing Inquiry 32 (1):e12696.
    Shared governance in hospitals promotes the inclusion of nurses' expertise, knowledge and skills in organisational processes, and nurses increasingly fulfil positions in organisational hierarchies. However, incorporating nursing expertise in strategic governance structures might be complicated, as these structures are primarily linked to managerial and biomedical expertise. Drawing on a Foucauldian perspective on knowledge and power, intertwined and embedded in everyday (inter)actions, we study how newly appointed directors of nursing challenge these dominant ‘modes of knowing’. By focusing on a (Dutch) healthcare (...)

    Quantum Reality, Perspectivalism and Covariance.Dennis Dieks - 2019 - Foundations of Physics 49 (6):629-646.
    Paul Busch has emphasized on various occasions the importance for physics of going beyond a merely instrumentalist view of quantum mechanics. Even if we cannot be sure that any particular realist interpretation describes the world as it actually is, the investigation of possible realist interpretations helps us to develop new physical ideas and better intuitions about the nature of physical objects at the micro level. In this spirit, Paul Busch himself pioneered the concept of “unsharp quantum reality”, according to which (...)

    Indecent Calvinists and Vanilla Secularism: Redefining Decency in The Netherlands.Matthea Westerduin, Mariecke van den Berg & Janneke Stegeman - 2018 - Feminist Theology 26 (3):308-320.
    Using Althaus-Reid’s Indecent Theology as a methodology, this article contributes to reflections on the contextuality and physical dimension of Dutch theology: its relation to the Protestant white bodies of its practitioners and its support of and contributions to colonial power and colonial racializing discourse. We do this in a context of a ‘return to decency’ in political discourse in which ‘our’ Calvinist roots are evoked to construct a ‘shared’ past. Using two case studies, we analyse how the in/decent is constructed (...)

  17. Becoming, relativity and locality.Dennis Dieks - unknown
    It is a central aspect of our ordinary concept of time that history unfolds and events come into being. It is only natural to take this seriously. However, it is notoriously difficult to explain further what this `becoming' consists in, or even to show that the notion is consistent at all. In this article I first argue that the idea of a global temporal ordering, involving a succession of cosmic nows, is not indispensable for our concept of time. Our experience (...)

    Quantum mechanics without the projection postulate and its realistic interpretation.D. Dieks - 1989 - Foundations of Physics 19 (11):1397-1423.
    It is widely held that quantum mechanics is the first scientific theory to present scientifically internal, fundamental difficulties for a realistic interpretation (in the philosophical sense). The standard (Copenhagen) interpretation of the quantum theory is often described as the inevitable instrumentalistic response. It is the purpose of the present article to argue that quantum theory doesnot present fundamental new problems to a realistic interpretation. The formalism of quantum theory has the same states—it will be argued—as the formalisms of older physical (...)

    Niels Bohr and the Formalism of Quantum Mechanics.Dennis Dieks - unknown
    It has often been remarked that Bohr's writings on the interpretation of quantum mechanics make scant reference to the mathematical formalism of quantum theory; and it has not infrequently been suggested that this is another symptom of the general vagueness, obscurity and perhaps even incoherence of Bohr's ideas. Recent years have seen a reappreciation of Bohr, however. In this article we broadly follow this "rehabilitation program". We offer what we think is a simple and coherent reading of Bohr's statements about (...)

    The Gibbs Paradox and the Distinguishability of Identical Particles.Marijn A. M. Versteegh & Dennis Dieks - unknown
    Classical particles of the same kind are distinguishable: they can be labeled by their positions and follow different trajectories. This distinguishability affects the number of ways W a macrostate can be realized on the micro-level, and via S=k ln W this leads to a non-extensive expression for the entropy. This result is generally considered wrong because of its inconsistency with thermodynamics. It is sometimes concluded from this inconsistency, notoriously illustrated by the Gibbs paradox, that identical particles must be treated as (...)

  22. Special relativity and the flow of time.Dennis Dieks - 1988 - Philosophy of Science 55 (3):456-460.
    N. Maxwell (1985) has claimed that special relativity and "probabilism" are incompatible; "probabilism" he defines as the doctrine that "the universe is such that, at any instant, there is only one past but many alternative possible futures". Thus defined, the doctrine is evidently prerelativistic as it depends on the notion of a universal instant of the universe. In this note I show, however, that there is a straightforward relativistic generalization, and that therefore Maxwell's conclusion that the special theory of relativity (...)

    Achieving understanding of nature is one of the aims of science. In this paper we offer an analysis of the nature of scientific understanding that accords with actual scientific practice and accommodates the historical diversity of conceptions of understanding. Its core idea is a general criterion for the intelligibility of scientific theories that is essentially contextual: which theories conform to this criterion depends on contextual factors, and can change in the course of time. Our analysis provides a general account of (...)

    Mechanisms, Explanation and Understanding in Physics.Dennis Dieks - unknown
    The Scientific Revolution is often associated with a transition to a ``mechanistic'' world view. However, ``mechanization'' is not the term that best captures the distinctive nature of modern physics: ``mathematization'' would be a better characterization. Modern physics attempts to find mathematical relations between quantities, and does not require that these relations be interpreted in terms of mechanisms. Moreover, in modern physics there are cases in which it is unnatural to give the mathematical formalism a mechanistic interpretation, even if ``mechanistic'' is (...)

  27. A Perspectival Version of the Modal Interpretation of Quantum Mechanics and the Origin of Macroscopic Behavior.Gyula Bene & Dennis Dieks - 2001 - Foundations of Physics 32 (5):645-671.
    We study the process of observation (measurement), within the framework of a “perspectival” (“relational,” “relative state”) version of the modal interpretation of quantum mechanics. We show that if we assume certain features of discreteness and determinism in the operation of the measuring device (which could be a part of the observer's nerve system), this gives rise to classical characteristics of the observed properties, in the first place to spatial localization. We investigate to what extent semi-classical behavior of the object system (...)

    Quantum statistics, identical particles and correlations.Dennis Dieks - 1990 - Synthese 82 (1):127 - 155.
    It is argued that the symmetry and anti-symmetry of the wave functions of systems consisting of identical particles have nothing to do with the observational indistinguishability of these particles. Rather, a much stronger conceptual indistinguishability is at the bottom of the symmetry requirements. This can be used to argue further, in analogy to old arguments of De Broglie and Schrödinger, that the reality described by quantum mechanics has a wave-like rather than particle-like structure. The question of whether quantum statistics alone (...)

    Physics and the direction of causation.D. Dieks - 1986 - Erkenntnis 25 (1):85 - 110.
    Two proposals for a physicalistic analysis of causation — the so-called transference model and an account given by J. L. Mackie — are examined and found wanting on the score of physical objectivity. This shortcoming can be remedied, but it is further argued that both proposals embody a too restricted conception of what a physicalistic analysis of causation should be. A more general program is proposed.

    In his general theory of relativity (GR) Einstein sought to generalize the special-relativistic equivalence of inertial frames to a principle according to which all frames of reference are equivalent. He claimed to have achieved this aim through the general covariance of the equations of GR. There is broad consensus among philosophers of relativity that Einstein was mistaken in this. That equations can be made to look the same in different frames certainly does not imply in general that such frames are (...)

  31. How Classical Particles Emerge From the Quantum World.Dennis Dieks & Andrea Lubberdink - 2011 - Foundations of Physics 41 (6):1051-1064.
    The symmetrization postulates of quantum mechanics (symmetry for bosons, antisymmetry for fermions) are usually taken to entail that quantum particles of the same kind (e.g., electrons) are all in exactly the same state and therefore indistinguishable in the strongest possible sense. These symmetrization postulates possess a general validity that survives the classical limit, and the conclusion seems therefore unavoidable that even classical particles of the same kind must all be in the same state—in clear conflict with what we know about (...)

    Events and covariance in the interpretation of quantum field theory.Dennis Dieks - unknown
    In relativistic quantum field theory the notion of a local operation is regarded as basic: each open space-time region is associated with an algebra of observables representing possible measurements performed within this region. It is much more difficult to accommodate the notions of events taking place in such regions or of localized objects. But how can the notion of a local operation be basic in the theory if this same theory would not be able to represent localized measuring devices and (...)

    'Holographic' relations between theories have become a main theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard 't Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic 'AdS/CFT' duality was introduced, which since has been heavily studied in the string theory community and beyond. Recently, Erik Verlinde has proposed (...)

    Identical particles and weak discernibility.Dennis Dieks & Marijn Versteegh - unknown
    Saunders has recently claimed that ``identical quantum particles'' with an anti-symmetric state (fermions) are weakly discernible objects, just like irreflexively related ordinary objects in situations with perfect symmetry (Black's spheres, for example). Weakly discernible objects have all their qualitative properties in common but nevertheless differ from each other by virtue of (a generalized version of) Leibniz's principle, since they stand in relations an entity cannot have to itself. This notion of weak discernibility has been criticized as question begging, but we (...)

    Reichenbach’s Transcendental Probability.Fedde Benedictus & Dennis Dieks - 2015 - Erkenntnis 80 (1):15-38.
    The aim of this article is twofold. First, we shall review and analyse the neo-kantian justification for the application of probabilistic concepts in science that was defended by Hans Reichenbach early in his career, notably in his dissertation of 1916. At first sight this kantian approach seems to contrast sharply with Reichenbach’s later logical positivist, frequentist viewpoint. But, and this is our second goal, we shall attempt to show that there is an underlying continuity in Reichenbach’s thought: typical features of (...)

  38. The adolescence of relativity: Einstein, Minkowski, and the philosophy of space and time.Dennis Dieks - unknown
    An often repeated account of the genesis of special relativity tells us that relativity theory was to a considerable extent the fruit of an operationalist philosophy of science. Indeed, Einstein’s 1905 paper stresses the importance of rods and clocks for giving concrete physical content to spatial and temporal notions. I argue, however, that it would be a mistake to read too much into this. Einstein’s operationalist remarks should be seen as serving rhetoric purposes rather than as attempts to promulgate a (...)

    Summary A recurrent theme in the philosophical literature on the special theory of relativity is the question as to the reality of the Lorentz contraction. It is often suggested that there is a difference between the Lorentz-FitzGerald contraction in the pre-relativistic ether theory and the Lorentz contraction from special relativity in the sense that the former is a real contraction of matter conditioned by dynamical laws, whereas the latter should be compared with the apparent changes in the size of objects (...)

    Perspectival Quantum Realism.Dennis Dieks - 2022 - Foundations of Physics 52 (4):1-20.
    The theories of pre-quantum physics are standardly seen as representing physical systems and their properties. Quantum mechanics in its standard form is a more problematic case: here, interpretational problems have led to doubts about the tenability of realist views. Thus, QBists and Quantum Pragmatists maintain that quantum mechanics should not be thought of as representing physical systems, but rather as an agent-centered tool for updating beliefs about such systems. It is part and parcel of such views that different agents may (...)

    Modal interpretations have the ambition to construe quantum mechanics as an objective, man-independent description of physical reality. Their second leading idea is probabilism: quantum mechanics does not completely fix physical reality but yields probabilities. In working out these ideas an important motif is to stay close to the standard formalism of quantum mechanics and to refrain from introducing new structure by hand. In this paper we explain how this programme can be made concrete. In particular, we show that the Born (...)
