Emergent quantum mechanics (EmQM) explores the possibility of an ontology for quantum mechanics. The resurgence of interest in realist approaches to quantum mechanics challenges the standard textbook view, which represents an operationalist approach. The possibility of an ontological, i.e., realist, quantum mechanics was first introduced with the original de Broglie–Bohm theory, which has also been developed in another context as Bohmian mechanics. This Editorial introduces a Special Issue featuring contributions which were invited as part of the David Bohm Centennial symposium of the EmQM conference series (www.emqm17.org). Questions directing the EmQM research agenda are: Is reality intrinsically random or fundamentally interconnected? Is the universe local or nonlocal? Might a radically new conception of reality include a form of quantum causality or quantum ontology? What is the role of the experimenter agent in ontological quantum mechanics? The Special Issue also includes research examining ontological propositions that are not based on the Bohm-type nonlocality. These include, for example, local, yet time-symmetric, ontologies, such as quantum models based upon retrocausality. This Editorial provides topical overviews of thirty-one contributions which are organized into seven categories to provide orientation.

Emergent Quantum Mechanics

This paper addresses the long-standing question of how it may be explained that the three charged leptons (the electron, muon and tau particle) have different masses, despite their conformity in other respects. In the field of Emergent Quantum Mechanics non-singular electron models are being revisited, and from this exploration has come a possible answer. In this paper a deformable droplet model is considered. It is shown how the model can be made self-consistent, whilst obeying the laws of momentum and energy conservation as well as Larmor’s radiation law. The droplet appears to have three different static equilibrium configurations, each with a different mass. Tentatively, these three equilibrium masses were assumed to correspond with the measured masses of the charged leptons. The droplet model was tuned accordingly, and was thereby completely quantified. The dynamics of the droplet then showed a “De Broglie-like” relation p = K / λ . Beat patterns in the vibrations of the droplet play the role of the matter waves of usual quantum mechanics. The value of K , calculated by the droplet theory, practically equals Planck’s constant: K ≅ h . This fact seems to confirm the correctness of identifying the three types of charged leptons with the equilibria of a droplet of charge.

Families With Children

The articles in the special issue on Families, Poverty, and Public Policies focus on poor families with children and develop a central theme: that current policies are not sufficiently responsive to the emerging reality of large numbers of children living in poverty. This article first provides a context for considering the results reported in these articles by noting recent public policy, demographic, and socioeconomic trends that will influence these families in the future. Second, the articles are briefly reviewed and compared with an emphasis on demonstrating the need for diversity in programs to respond to the diverse needs of these families. Third, a research agenda related to the articles is discussed. The conclusion of the article addresses the role of research in the policy process.

The Cold War

The end of the Cold War helped to prompt new interest in the study of ideas in international politics. Once the province of a few dedicated researchers on the fringes of the discipline, scholarship on the role of ideas now occupies an important place in the mainstream of North American and especially European international relations research. The five articles in this special issue of the journal are intended to move the research agenda on ideas and the end of the Cold War to a new level of rigor. They develop new models of how ideas affected the outcome and, in so doing, take stock of this event to refine our understanding of how ideas work in international politics. Although we seek a deeper understanding of the end of the Cold War itself, we also use this seminal case to clarify and advance the debate over the role of ideas in international politics more generally.

This essay is intended as an informal introduction to the papers and commentaries on the state contained in this special issue of Environmental and Planning A. It is presented in the form of a research agenda, which itself may provoke further debate on the role of the state in sociospatial processes. Two main themes are identified. The first concerns the form of the capitalist state and its historical evolution. The second addresses the functions of the state apparatus.

Recently great interest has been devoted toward a better understanding of a possible deep relation between large size structures we observe today in the universe and the quantum fluctuations at Planck time. Within such a context this paper provides us with a procedure for how to obtain a faithful description of the Bohr energy levels for hydrogen like atoms, starting from a generalization of a quantum relation for primordial black holes’ masses at Planck time. The key role of quantum mechanics in such a description is emphasized and the classical correspondence taking us from Newton’s law for interacting masses to Coulomb’s law for interacting charges evidenced.

In this paper, we discuss classical and quantum aspects of cosmological models in the Brans–Dicke theory. First, we review cosmological bounce solutions in the Brans–Dicke theory that obeys energy conditions (without ghost) for a universe filled with radiative fluid. Then, we quantize this classical model in a canonical way, establishing the corresponding Wheeler–DeWitt equation in the minisuperspace, and analyze the quantum solutions. When the energy conditions are violated, corresponding to the case ω<−32, the energy is bounded from below and singularity-free solutions are found. However, in the case ω>−32, we cannot compute the evolution of the scale factor by evaluating the expectation values because the wave function is not finite (energy spectrum is not bounded from below). However, we can analyze this case using Bohmian mechanics and the de Broglie–Bohm interpretation of quantum mechanics. Using this approach, the classical and quantum results can be compared for any value of ω.

This special issue continues the discussion of the role of emotion in discourse (see Russian Journal of Linguistics 2015 (1) and 2018, 22 (1)) which, as testified by the burgeoning body of literature in the field, has become more prominent in different spheres and contexts of public life. This time we focus on emotionalisation of media discourse. We highlight the intensification of emotions in media and, showcasing contributions from international authors, critically reflect on constructions, functions and pragmatic purposes of emotions in media discourse. Our aim is to investigate emotions in the media from semiotic, pragmatic and discursive perspectives against the contemporary socio-political background in which traditional notions concerning the role of media are being noticeably changed. In this introductory article, we also put forward an agenda for further research by briefly outlining three main areas of exploration: the logics of media production and reception , the boundaries of media discourse, and the semiotic resources deployed to construct emotionality . We then present the articles in this issue and highlight their contributions to the study of linguistic representations of emotions. We then summarise the main results and suggest a brief avenue for further research.

Principle Of Complementarity

The article compares views of C.G. Jung and N.O. Lossky on the nature of time, including in the context of contemporary to them physical theories - quantum mechanics by W. Pauli and relativistic physics by A. Einstein. In particular, the author points to the similarity of ideas of both thinkers that the psyche relativizes time not only subjectively, but also objectively. Jung and Lossky provide this statement with a similar empirical basis, for example, the researches of T. Flournoy, as well as similar theoretical arguments by postulating a fundamental acausal principle of the connection of all things, which is better suited for describing psychic and some physical phenomena than the classical causal explanation. In analytical psychology, such a principle is synchronicity, in hierarchical personalism - gnoseological coordination. Both concepts are genetically related to the G.W. Leibniz idea of pre-established harmony, which was reinterpreted by Jung and Lossky through different worldview foundations. Jung in his reasoning relied on the transcendental idealism of I. Kant, the principle of complementarity and the discoveries of quantum mechanics, Lossky - on intuitivism, the principle of subordination and on his own interpretation of Einsteins theories. Jung comes to the conclusion that the psyche has a timeless character, and Lossky comes to the conclusion that it has a super-temporal character. Jungs timelessness indicates the transcendental nature of psyche and the strive to get away from the classical causal explanation, saving it according to the principle of complementarity only to consider the phenomenal side of being and mainly physical processes. One of the pioneers of quantum mechanics Pauli was of the same opinion in general. Because of there is nothing transcendent in hierarchical personalism, Losskys super-temporality is of a strive to find a deeper basis for occurring in time processes, and, according to the principle of subordination, to include time in the hierarchical structure of the universe, prescribing for it a role of one of the two key forms of psychic and psycho-material processes characteristic of a certain stage of being.

Metaphysics, as discipline dealing with the most fundamental aspects of reality, studies the essence of entities, leaving to particular sciences the study of empirical, specific, changeable and unstable aspects. In this sense metaphysics is close to ontology, tackling problems as the existence of God, the being in himself, the immortality of consciousness, the origin and meaning of the universe. Speculative physics pushes its interest to metaphysical questions too, both at atechnical (mathematical) level, and at the level of thought (in relation to philosophy). In recentyears interesting concepts and ideas have been considered and developed, involving the latest unified quantum-relativistic theories and the consequences on reality deriving from them.The search for a meaning of life, one of Anscombe’s themes, finds ferment in the search for meaning about the existence of our universe in itself and as a possible part of a multiverse containing it.The problem of measurement in quantum mechanics appears from the application of themathematical formalism to macroscopic situations and the central position of the observer in this process has produced a deviation towards a metaphysical subjectivism. There are controversial aspects about the role of consciousness in the process of reducing the wave function of quantum mechanics. This narrows the field of validity of some fundamental principles during the interaction between microsystems and macrosystems, with consequent diversification of thedefinition of the ontological state of consciousness and reality. (Local) holism has often been linked to Wittgenstein. From Wittgenstein’s answers to the paradoxes of communication and conceptual relativism, a tension emerges in his vision of linguistic games and in his mental experiments, traditionally interpreted in contrasting ways. This tension can be better understoodthrough some reflections by Wittgenstein on Einstein and his theory of relativity.

The causal stochastic interpretation of relativistic quantum mechanics has the problems of superluminal velocities, motion backward in time and the incorrect non-relativistic limit. In this paper, according to the original ideas of de Broglie, Bohm and Takabayasi, we introduce simultaneously a quantum mass and a quantum metric of a curved spacetime to obtain a correct relativistic theory free of mentioned problems.
