We consider the extension of a (strict) preference over a set to its power set. Elements of the power set are non-resolute outcomes. The final outcome is determined by an “(external) chooser” which is a resolute choice function. The individual whose preference is under consideration confronts a set of resolute choice functions which reflects the possible behaviors of the chooser. Every such set naturally induces an extension axiom (i.e., a rule that determines how an individual with a given preference over (...) alternatives is required to rank certain sets). Our model allows to revisit various extension axioms of the literature. Interestingly, the Gärdenfors (1976) and Kelly (1977) principles are singled-out as the only two extension axioms compatible with the non-resolute outcome interpretation. (shrink)

BackgroundStudies conducted in the health sector have determined a positive relationship between job satisfaction and work engagement. However, this paper reveals that this relationship turns into a negative or non-significant relationship during the COVID-19 pandemic. We explore the reasons for inconsistency in research findings in this critical period through a meta-analysis.MethodsThis study was conducted according to the PRISMA guidelines and PICO framework. Online databases including Web of Science, Scopus, PubMed, ProQuest, Google Scholar, and additional records from other databases were searched (...) without any time limitation, and all studies published in English that reported the correlation between work engagement and job satisfaction were included in the analysis. In total, 36 individual correlation coefficients were synthesized. R statistical language was used to analyze the data.ResultA total of 36 studies with a sample size of 16,087 were synthesized. The overall effect size was found as r = 0.57. While the moderating effect of national culture was not statistically significant, presence of COVID-19 as the significant moderator explained 37.08% of effect size heterogeneity. Such that the presence of COVID-19 has transformed the positive relationship between work engagement and job satisfaction into a negative but statistically non-significant relationship.ConclusionThis study empirically challenges the existing assumptions about the positive link between work engagement and job satisfaction. The results of the research can be a guide for managers and policymakers. Specifically, based on these results, different mechanisms can be put in place to support work engagement and, in turn, job satisfaction in the COVID-19 process. (shrink)

The “theorems” showing the impossibility of ascribing to individual quantum systems a definite value of a set of observables, not necessarily commuting,1–4 are based on the tacit assumption that eachindividual spin component has a discrete dichotomic value. We show explicitly that it is possible to introduce continuous hidden variables for individual spins which avoid these quantum paradoxes without changing any of the observed quantum mechanical results.

Exact wavelet solutions of the wave equation for accelerating potentials are found and applied to single individual events in Stern-Gerlach experiment.

Technology assessment (TA) is an important instrument for the regulation of innovation. From the perspective of sociology of knowledge, the regulatory process can be understood as a complex interplay between different forms of knowledge. The prevailing instruments of TA, expertise and participation, are both facing difficulties in dealing with the limits and impasses of regulatory knowledge in the realm of innovation. Nevertheless, as is argued in this article, reflexive forms of TA offer a good, if not the only, answer to (...) the question of how we can deal with the contradictions and paradoxes involved in the regulation of innovation.

This article is analysing the legal perspective on whistleblowing, at European and national level, focusing on the scientific studies’ results and theories, emphasizing nuances which worth discussing in order to a better understanding of the social phenomenon and of individual psychological decision process for reporting a wrongdoing or the suspicion of a possible breach. We are also arguing that current whistleblower regulations must take into account both the European directive and recent research in this field, pointing out some question which (...) are raising from the lack of the ethical and cultural focused research of Romanian society perspective on whistleblowing, considering also the recent past experiences of Romanians with political police actions in years of communism. We are establishing a few research directions which we conclude that could bring the knowledge to drawing a more relevant and applicable whistleblowing law. (shrink)

Der Produktionsfaktor Wissen produziert nicht nur Wissen, sondern zugleich auch Unwissen. Die Wissensgesellschaft ist auch eine Risikogesellschaft, in der die Normalität von Unfällen ebenso zu akzeptieren ist, wie das Fungieren der Gesellschaft als Labor neuer Technologien. Vor diesem Hintergrund der Gesellschaft als Wissensgesellschaft mit ihren beiden Seiten der Innovation und des Risikos ist die Frage zu sehen, wie die moderne Gesellschaft die ihr spezifische Problematik bearbeitet, mehr denn je von einem nicht auf seine positive Seite festlegbaren Wissen abhängig zu sein.

Technical Novel by Andrei Platonovich Platonov shows the process of organizing and constructing a technological utopia. Technological utopianism, according to Howard P. Segal, is defined as "the use of hardware and of knowledge to create and preserve an intendedly perfect society."1 Segal emphasizes that the extent to which technology shapes a society's values, institutions, techniques, and way of life is what distinguishes a technological society from previous societies. In Technical Novel, the main characters strive toward building an ideal society by (...) laying down basic... (shrink)

Localised configurations of the free electromagnetic field are constructed, possessing properties of massive, spinning, relativistic particles. In an inertial frame, each configuration travels in a straight line at constant speed, less than the speed of lightc, while slowly spreading. It eventually decays into pulses of radiation travelling at speedc. Each configuration has a definite rest mass and internal angular momentum, or spin. Each can be of “electric” or “magnetic” type, according as the radial component of the magnetic or electric field (...) vanishes in the rest frame, and each has an “antiparticle.” Any such configuration, of electric or magnetic type, is characterized in part by a set of labels (κ, ω0, σ,l, m), where ω0 is the mean of the angular frequencies of the plane waves making up the configuration, σ is the variance of those frequencies, κ is a positive constant with dimensions of action, andl, m are angular momentum “quantum numbers” withl a positive integer andm an integer such that ‖m‖≤l. The rest energy of the “particle” is κω0, its spin is κ ‖m‖, and its lifetime is of the order of 1/σ. Its antiparticle has ω0 replaced by −ω0. (shrink)

Davidson (in: LePore (ed), pp 433–46, 1986) uses the existence of malapropisms to motivate a model of linguistic communication where communication succeeds between conversational partners without their having to rely on conventional meanings. Davidson uses this model to then claim that there is no such thing as a conventional language shared by a linguistic community which must be known in advance for linguistic communication to succeed. However, for many cases, Davidson relies on there being standard lines of interpretation for communication (...) to be successful according to his model. Dummett (in: LePore (ed), pp 459–76, 1986) calls out Davidson on his reliance on the notion of standard lines, but does not clearly spell out why that is a problem for Davidson’s claim. I, taking cue from Dummett’s complaint, argue that the reliance on standard lines of interpretation is unavoidable for Davidson’s model and yet detrimental for Davidson’s claim. (shrink)

The mathematical and physical aspects of the conformal symmetry of space-time and of physical laws are analyzed. In particular, the group classification of conformally flat space-times, the conformal compactifications of space-time, and the problem of imbedding of the flat space-time in global four-dimensional curved spaces with non-trivial topological and geometrical structure are discussed in detail. The wave equations on the compactified space-times are analyzed also, and the set of their elementary solutions constructed. Finally, the implications of global compactified space-times for (...) cosmology are discussed. It is argued that the recent discovery of periodic structure of matter distribution on large distances strongly suggests that the global cosmological space-time should be close. Next we analyze the inflation scalar field in the inflationary model of universe evolution considered on the spatially compact Robertson-Walker space-time. It is shown that the energy distribution in this model is periodic and the periods and density decrease with increasing distance, in striking agreement with experimental data. Our model of the universe also provides a definite predictions for the energy distribution, polar and azimuthal, considered as a function of angles θ and φ. These predictions should be tested with the new astronomical data. (shrink)

The symplectic structures (brackets, Hamilton's equations, and Lagrange's equations) for the Dirac electron and its classical model have exactly the same form. We give explicitly the Poisson brackets in the dynamical variables (x μ,p μ,v μ,S μv). The only difference is in the normalization of the Dirac velocities γμγμ=4 which has significant consequences.

The single postulate of Coulomb-Clausius potential between charges allows one to derive all of Maxwell's equations with an explicit form for polarizability.

Pauli's five-dimensional Dirac equation in projective space, which results in an anomalous magnetic moment term in four dimensions, is related to the Schuster-Blackett law of the magnetic field of rotating bodies and to the recent results on the gyromagnetic ratio in Kaluza-Klein theories.

We compute the energy tensor and the energy-momentum tensor for electrodynamics coupled to the current of a charged scalar field and for electrodynamics coupled tothe current of a Dirac spinor field, without using the equations of motion.

This is the first in a series of papers in which a method of harmonic analysis in terms of functions over the groupSU(2) is applied to the description of interaction between matter and the electromagnetic field. Carmeli'sSU(2) formulation of Maxwell's equations is extended to anSU(2) formulation of the equations for the electromagnetic vector potential. The four functions which describe the vector potential are expanded in a generalized Fourier series [SU(2) harmonic analysis] and the equations for the coefficients are derived. These (...) equations are not independent of each other, but in a given order they can be solved consecutively one at a time. (shrink)

QED is a fundamental microscopic theory satisfying all the conservation laws and discrete symmetries C, P, T. Yet, dissipative phenomena, organization, and self-organization occur even at this basic microscopic two-body level. How these processes come about and how they are described in QED is discussed. A possible new phase of QED due to self-energy effects leading to self-organization is predicted.

Comparative study of the aesthetic ideas of Ram Chandra Shukla, 1884-1941, Hindi critic, Benedictus de Spinoza, 1632-1677, and Bertrand Russell, 1872-1970, philosophers.

Ever since Kripke’s influential arguments against descriptivism philosophers have attempted to provide solutions to Frege’s puzzle of substitution failure that adhere to Naïve Semantics—the view that names contribute their referents and referents alone to propositions expressed by sentences containing them. Recently, philosophers have also appealed to psychological objects called mental files, which are used to represent and store information on individuals, in solving the puzzle. Combining the two promises to revive a simple commonsensical theory while, at least prima facie, doing (...) away with the need to rely on Fregean senses. Though I welcome the combined approach, I argue that the only plausible version of it is a pretense-based one. (shrink)

Jeshion (New essays on singular thought, Oxford University Press, Oxford, 2010b) believes that singular thought is implemented by the tokening of mental files (MFC). She also believes that an individual’s being significant to the agent is necessary and sufficient for the agent’s having singular thought about the individual (Cognitivism). Goodman (Rev Philos Psychol 7(2):437–461, 2016a, Philos Q 66:236–260, 2016b) argues that mental files created under a description lead to descriptive not singular thought. She uses this to criticize Cognitivism’s sufficiency claim (...) and MFC. I show that this criticism rests on a faulty conception of the singular thought versus descriptive thought distinction and such files indeed lead to singular thought. This in turn shows that Cognitivism’s necessity claim is false. (shrink)

We use joint probabilities to analyze the EPR argument in the Bohm's example of spins.(1) The properties of distribution functions for two, three, or more noncommuting spin components are explicitly studied and their limitations are pointed out. Within the statistical ensemble interpretation of quantum theory (where only statements about repeated events can be made), the incompleteness of quantum theory does not follow, as the consistent use of joint probabilities shows. This does not exclude a completion of quantum mechanics, going beyond (...) it, by a more general theory of single events, using hidden variables, for example. (shrink)

Recent assertions that the present particle physics is on the path of a “final theory” which cannot be reduced to more fundamental ones is critically examined and confronted with a counter-thesis.

We show that it is possible to consider parity and time reversal, as basic geometric symmetry operations, as being absolutely conserved. The observations of symmetry-violating pseudoscalar quantities can be attributed to the fact that some particles, due to their internal structure, are not eigenstates of parity or CP, and there is no reason that they should be. In terms of a model it is shown how, in spite of this, pseudoscalar terms are small in strong interactions. The neutrino plays an (...) essential role in these considerations. (shrink)

Participation of a broad variety of actors in decision-making processes has become an important issue in science and technology policy. Many authors claim the involvement of stakeholders and of the general public to be a core condition for legitimate and sustainable decision making. In the last decades, a wide spectrum of procedures has been developed to realize biotechnological citizenship. These procedures, composed of multiactor arenas, are either located in close relation to the system of politics, or, as in the case (...) of administrative decision making, more closely to the system of law. In the latter case, a problematic constellation arises. Here, law and science can build a technoscientific normativity that systematically excludes political discourse. The law, although intending to provide for political freedom and citizenship rights, at the end appears to be an ‘‘iron cage’’ for political communication. (shrink)

For an arbitrary potential V with classical trajectoriesx=g(t), we construct localized oscillating three-dimensional wave lumps ψ(x, t,g) representing a single quantum particle. The crest of the envelope of the ripple follows the classical orbitg(t), slightly modified due to the potential V, and ψ(x, t,g) satisfies the Schrödinger equation. The field energy, momentum, and angular momentum calculated as integrals over all space are equal to the particle energy, momentum, and angular momentum. The relation to coherent states and to Schrödinger waves is (...) also discussed. (shrink)

Care Ethics needs to make clear and defensible normative claims. Michael Slote’s work shows how accounts taking care as a sentimental motive can do the needful. Such motive accounts of care can also provide a way to capture the important distinction between care and justice approaches to morality. However, it is important for Care Ethics to establish harmony between caring motives and acting rightly. Slote’s account does so at the cost of an unintuitive account of obligation. We propose another way (...) to capture this harmony. (shrink)

The Dirac field and its quanta are obtained from the imposition of an infinite member of Dirac 2 nd class constraints on a system of complex scalar fields having an indefinite internal metric. The spin-1/2 character of the constrained system follows from constraint-induced coupling of the scalar system's independent internal and space-time symmetries, from constraint restrictions on allowed symmetries. The resulting spinor field quanta are seen to exist as a class of “elementary excitations” belonging to a dynamical algebra existing naturally (...) within the system of complex scalar fields.

The incongruence between quantum theory and relativity theory is traced to the probability interpretation of the former. The classical continium interpretation of ψ removes the difficulty. How quantum properties of matter and light, and in particular the radiative problems, like spontaneous emission and Lamb shift, may be accounted in a first quantized Maxwell-Dirac system is discussed.

In a previous article by two of the present authors Carmeli's group-theoretic method for the formulation of wave equations was applied to the case of the electromagnetic field, and the equations for the vector potential were derived. In the present paper a quantization procedure for these equations is carried out in the Lorentz gauge. It involves two independent variables, corresponding to the number of degrees of freedom of the electromagnetic field in a Hilbert space with a positive-definite metric. Conserved quantities (...) are derived. (shrink)

The Dignity of the Children according to the New Testament teaching should be a landmark for modern era. New Testament raised the dignity of the unborn child, from a simple mass of cells to a child who has the right to be born and live. The child born has the value of a person that to enjoy family and society not only for economic potential but for the soul value as they bear the image of God. Children of different ages (...) have the right to be baptized, have access to the grace of the Sacraments and become saints. In fact the true dignity of man is his power to become a saint. And the child is the image of the saint, heir of the Heaven. (shrink)

The nonlinear integro-differential equation, obtained from the coupled Maxwell-Dirac equations by eliminating the potential Aμ, is solved by iteration rather than perturbation. The energy shift is complex, the imaginary part giving the spontaneous emission. Both self-energy and vacuum polarization terms are obtained. All results, including renormalization terms, are finite.

Is Europe's continuing crisis merely a financial one? Tackling issues ranging from Europe's legal, institutional and cultural identity to its border, citizenship and integration policies, and looking forward to its legacy for the future, the contributors to this volume interrogate the various dimensions and contours of the European crisis. By revisiting Derrida's diagnosis of the crisis of European identity, they simultaneously propose a new direction for Europe, and an alternative response to today's crisis.

Proponents of Veritism believe that truth is the sole non-instrumental epistemic good. This view is often taken to entail that all truths should be of equal epistemic value. Hence, it is put under stress by the presence of trivial truths: truths to which we attach relatively little or no epistemic value. Pritchard, in the defense of Veritism, has tried to argue that the best way to understand the implications of Veritism is to think in terms of how an intellectually virtuous (...) inquirer would pursue truth. Furthermore, he thinks that such an inquirer would prefer weighty truths and set aside trivial ones. As such, he thinks that our epistemic disregard for trivial truths is just to be expected given Veritism. We argue that Pritchard’s defense of Veritism fails, and the problem of trivial truths remains a significant challenge for Veritism. (shrink)
