Physical basis for minimal time-energy uncertainty relation.Y. S. Kim &Marilyn E. Noz -1979 -Foundations of Physics 9 (5-6):375-387.detailsA physical basis for the minimal time-energy uncertainty relation is formulated from basic high-energy hadronic properties such as the resonance mass spectrum, the form factor behavior, and the peculiarities of Feynman's parton picture. It is shown that the covariant oscillator formalism combines covariantly this time-energy uncertainty relation with Heisenberg's space-momentum uncertainty relation. A pictorial method is developed to describe the spacetime distribution of the localized probability density.
Standing Waves in the Lorentz-Covariant World.Y. S. Kim &Marilyn E. Noz -2005 -Foundations of Physics 35 (7):1289-1305.detailsWhen Einstein formulated his special relativity, he developed his dynamics for point particles. Of course, many valiant efforts have been made to extend his relativity to rigid bodies, but this subject is forgotten in history. This is largely because of the emergence of quantum mechanics with wave-particle duality. Instead of Lorentz-boosting rigid bodies, we now boost waves and have to deal with Lorentz transformations of waves. We now have some nderstanding of plane waves or running waves in the covariant picture, (...) but we do not yet have a clear picture of standing waves. In this report, we show that there is one set of standing waves which can be Lorentz-transformed while being consistent with all physical principle of quantum mechanics and relativity. It is possible to construct a representation of the Poincaré group using harmonic oscillator wave functions satisfying space-time boundary conditions. This set of wave functions is capable of explaining the quantum bound state for both slow and fast hadrons. In particular it can explain the quark model for hadrons at rest, and Feynman’s parton model hadrons moving with a speed close to that of light. (shrink)

Schrödinger-Like Relativistic Wave Equation of Motion for the Lorentz-Scalar Potential.Y.-S. Huang -2001 -Foundations of Physics 31 (9):1287-1298.detailsA Schrödinger-like relativistic wave equation of motion for the Lorentz-scalar potential is formulated based on a Lagrangian formalism of relativistic mechanics with a scaled time as the evolution parameter. Applications of this Schrödinger-like formalism for the Lorentz-scalar potential are given: For the square-step potential, the predictions of this formalism are free from the Klein paradox, and for the Coulomb potential, this formalism yields the exact bound-state eigenenergies and eigenfunctions.
A Humean Argument for the Land Ethic?Y. S. Lo -2001 -Environmental Values 10 (4):523-539.detailsThis article examines an allegedly Humean solution provided by J. Baird Callicott to the problem of the is/ought dichotomy. It also examines an allegedly Humean argument provided by him for the land ethic's summary moral precept. It concludes that neither the solution nor the argument is Humean or cogent.
Non-Humean Holism, Un-Humean Holism.Y. S. Lo -2001 -Environmental Values 10 (1):113-123.detailsIn this article I argue that textual evidence from David Hume's A Treatise of Human Nature does not support J. Baird Callicott's professedly Humean yet holistic environmental ethic, which understands the community (e.g., the biotic community) as a ‘metaorganismic’ entity ‘over and above’ its individual members. Based on Hume's reductionist account of the mind and his assimilation of the metaphysical nature of the mind to that of the community, I also argue that a Humean account of the community should be (...) likewise reductionist. My conclusion is that Callicott's anti-reductionist holism is at least foreign to, and at worst incompatible with, Hume's philosophy. (shrink)
The land ethic and Callicott's ethical system (1980-2001): An overview and critique.Y. S. Lo -2001 -Inquiry: An Interdisciplinary Journal of Philosophy 44 (3):331 – 358.detailsThis article analyzes the evolution of the land ethic re-presented by J. Baird Callicott over the last two decades under pressure from the charge of misanthropy and ecofascism. It also traces the development of Callicott?s own ethical system, and examines its most current phase both in itself and in relation to his other theoretical commitments, including his particular version of moral monism, and his communitarian critique of egalitarianism. It concludes that Callicott?s communitarianism is by itself insufficient to fund an adequate (...) environmental ethic, and that for the sake of self-consistency he should either discard his moral monism or else further revise his ethical system.

Making and finding values in nature: From a Humean point of view.Y. S. Lo -2006 -Inquiry: An Interdisciplinary Journal of Philosophy 49 (2):123 – 147.detailsThe paper advances a Humean metaethical analysis of "intrinsic value" - a notion fundamental in moral philosophy in general and particularly so in environmental ethics. The analysis reduces an object's moral properties (e.g., its value) to the empirical relations between the object's natural properties and people's psychological dispositions to respond to them. Moral properties turn out to be both objective and subjective, but in ways compatible with, and complementary to, each other. Next, the paper investigates whether the Humean analysis can (...) support non-anthropocentric environmental ethical theories, which attribute intrinsic value to nonhuman natural entities. It argues that one of the most useful resources from Hume for non-anthropocentrism is his account of justice as an artificial virtue, which is a plausible model for the internalization of various environmentally friendly conventions and the creation of environmental values. Finally, the paper concludes that any Humean account of intrinsic value is empiricist all the way down. Moral questions about what things are intrinsically valuable, and to what extent they are so, are ultimately empirical questions about complex psychological capacities and dispositions of human beings, which cannot be single-handedly answered by philosophers a priori; and that ethics is more appropriately seen as an interdisciplinary investigation, requiring collaboration among the various psychological and social sciences, human biological and neurological sciences, and history and philosophy.

Reinforcing ethical decision making through corporate culture.Al Y. S. Chen,Roby B. Sawyers &Paul F. Williams -1997 -Journal of Business Ethics 16 (8):855-865.detailsBehaving ethically depends on the ability to recognize that ethical issues exist, to see from an ethical point of view. This ability to see and respond ethically may be related more to attributes of corporate culture than to attributes of individual employees. Efforts to increase ethical standards and decrease pressure to behave unethically should therefore concentrate on the organization and its culture. The purpose of this paper is to discuss how total quality (TQ) techniques can facilitate the development of a (...) cooperative corporate culture that promotes and encourages ethical behavior throughout an organization.

Lorentz deformation and the jet phenomenon. II. Explanation of the nearly constant average jet transverse momentum.S. H. Oh,Y. S. Kim &Marilyn E. Noz -1980 -Foundations of Physics 10 (7-8):635-639.detailsIt is shown that the jet mechanism derivable from the Lorentz deformation picture leads to a nearly constant average jet transverse momentum. It is pointed out that this is consistent with the high-energy experimental data. It is pointed out further that this result strengthens the physical basis for the minimal time-energy uncertainty combined covariantly with Heisenberg's space-momentum uncertainty relation.
Physical principles in quantum field theory and in covariant harmonic oscillator formalism.D. Han,Y. S. Kim &Marilyn E. Noz -1981 -Foundations of Physics 11 (11-12):895-905.detailsIt is shown that both covariant harmonic oscillator formalism and quantum field theory are based on common physical principles which include Poincaré covariance, Heisenberg's space-momentum uncertainty relation, and Dirac's “C-number” time-energy uncertainty relation. It is shown in particular that the oscillator wave functions are derivable from the physical principles which are used in the derivation of the Klein-Nishina formula.
Mixed emotional variants of gratitude: antecedent situations, cognitive appraisals, action tendencies, and psychosocial outcomes.Vincent Y. S. Oh &Eddie M. W. Tong -2023 -Cognition and Emotion 37 (3):572-585.detailsThis research provides an exploratory investigation of whether gift/help-receiving contexts that elicit mixed emotional variants of gratitude can be distinguished from typical gratitude-eliciting situations in their associated appraisals, action tendencies, and psychosocial effects. We examined 473 participants (159 males, 312 females, 2 others; Mage = 31.07) using a one-way four-conditions between-subjects experiment. Participants were randomly assigned to complete recall tasks describing four different gratitude-eliciting situations. Emotions, cognitive appraisals, action tendencies, and general psychosocial outcomes were assessed. Relative to a control condition (...) involving receiving a gift or help (gift/help condition), receiving something at the expense of a benefactor (benefactor-inconvenience condition) elicited gratitude-guilt; receiving something with an expectation of return (return-favour condition) elicited gratitude-disappointment and gratitude-anger; while receiving a disliked gift or receiving assistance that made things worse (backfire condition) primarily elicited gratitude-disappointment while also eliciting gratitude-anger and gratitude-guilt. Each condition was differentiable from control in their appraisals, action tendencies, and psychosocial effects. Notably, contexts which elicited mixed emotional variants of gratitude were characterised by the co-occurrence of conflicting appraisals such as pleasantness and unpleasantness or goal-congruence and goal-incongruence. Additionally, the return-favour and backfire conditions were most dissimilar from control, and were associated with the most negative action tendencies and psychosocial outcomes. (shrink)
How Does Homo Digitalis Empathize?Y. S. Borysenko -2023 -Anthropological Measurements of Philosophical Research 23:70-79.details_Purpose._ The article aimed at identifying the effects of modern digital technologies on the formation of human morality. _Theoretical basis._ The research base is the practical communicative philosophy. _Originality._ It lies in the fact that the article considered a moral interaction between a person and artificial intelligence. _Conclusions._ Nowadays modern digital technologies have acquired a new importance. Previously, they were only passive assistants. But now they are able to actively influence human nature not only from the outside, yet also from (...) the inside. Now they influence not only the form of thoughts but also their character. It is artificial intelligence that is the cause of the phenomenon of the "information bubble" ("echo chamber"). They are formed by mathematical algorithms for each individual user of the Internet. It is because of these algorithms, which are the basis of artificial intelligence, that we can conclude: they are guided only by strategic rationality. Therefore, they relate to the Internet user only as an object. That is why such a situation can also be a manifestation of the expansion of strategic rationality into the lifeworld, which gives rise to social pathologies. New digital technologies (first of all, social networks) are becoming an integral part of a person’s everyday life, and therefore the background of his/her life world. Virtual life becomes an important part of real life. However, virtual life is formed by the influence of the information stream, which constantly sets new "trends", including "trends" on morality. That is why a person begins to perceive only those events that are contained in this stream. Moreover, s\he can express his\her empathy only when s/he him/herself is able to join this stream and express it in virtual life. (shrink)

Correspondence between the classical and quantum canonical transformation groups from an operator formulation of the wigner function.Leehwa Yeh &Y. S. Kim -1994 -Foundations of Physics 24 (6):873-884.detailsAn explicit expression of the “Wigner operator” is derived, such that the Wigner function of a quantum state is equal to the expectation value of this operator with respect to the same state. This Wigner operator leads to a representation-independent procedure for establishing the correspondence between the inhomogeneous symplectic group applicable to linear canonical transformations in classical mechanics and the Weyl-metaplectic group governing the symmetry of unitary transformations in quantum mechanics.

Does von Neumann Entropy Correspond to Thermodynamic Entropy?Eugene Y. S. Chua -2021 -Philosophy of Science 88 (1):145-168.detailsConventional wisdom holds that the von Neumann entropy corresponds to thermodynamic entropy, but Hemmo and Shenker (2006) have recently argued against this view by attacking von Neumann's (1955) argument. I argue that Hemmo and Shenker's arguments fail due to several misunderstandings: about statistical-mechanical and thermodynamic domains of applicability, about the nature of mixed states, and about the role of approximations in physics. As a result, their arguments fail in all cases: in the single-particle case, the finite particles case, and the (...) infinite particles case. (shrink)
Decoherence, branching, and the Born rule in a mixed-state Everettian multiverse.Eugene Y. S. Chua &Eddy Keming Chen -2025 -Synthese 205 (4):1-32.detailsIn Everettian quantum mechanics, justifications for the Born rule appeal to self-locating uncertainty or decision theory. Such justifications have focused exclusively on a pure-state Everettian multiverse, represented by a wave function. Recent works in quantum foundations suggest that it is viable to consider a mixed-state Everettian multiverse, represented by a (mixed-state) density matrix. Here, we develop the conceptual foundations for decoherence and branching in a mixed-state multiverse, and extend arguments for the Born rule to this setting. This extended framework provides (...) a unification of 'classical' and 'quantum' probabilities, and additional theoretical benefits, for the Everettian picture. (shrink)
No Time for Time from No-Time.Eugene Y. S. Chua &Craig Callender -2021 -Philosophy of Science 88 (5):1172-1184.detailsPrograms in quantum gravity often claim that time emerges from fundamentally timeless physics. In the semiclassical time program time arises only after approximations are taken. Here we ask what justifies taking these approximations and show that time seems to sneak in when answering this question. This raises the worry that the approach is either unjustified or circular in deriving time from no–time.
Understanding Environmental Philosophy.Andrew Brennan &Y. S. Lo -2010 - Routledge.detailsEnvironmental philosophy is one of the exciting new fields of philosophy to emerge in the last forty years. "Understanding Environmental Philosophy" presents a comprehensive, critical analysis of contemporary philosophical approaches to current ecological concerns. Key ideas are explained, placed in their broader cultural, religious, historical, political and philosophical context, and their environmental policy implications are outlined. Central ideas and concepts about environmental value, individual wellbeing, ecological holism and the metaphysics of nature set the stage for a discussion of how to (...) establish moral rules and priorities, and whether it is possible to transcend human-centred views of the world. The reader is also helped with an annotated guide to further reading, questions for discussion and revision as well as boxed studies highlighting key concepts and theoretical material. A clear and accessible introduction to this most dynamic of subjects, "Understanding Environmental Philosophy" will be invaluable for a wide range of readers. (shrink)
The Time in Thermal Time.Eugene Y. S. Chua -forthcoming -Journal for General Philosophy of Science / Zeitschrift für Allgemeine Wissenschaftstheorie:1-24.detailsPreparing general relativity for quantization in the Hamiltonian approach leads to the `problem of time,' rendering the world fundamentally timeless. One proposed solution is the `thermal time hypothesis,' which defines time in terms of states representing systems in thermal equilibrium. On this view, time is supposed to emerge thermodynamically even in a fundamentally timeless context. Here, I develop the worry that the thermal time hypothesis requires dynamics -- and hence time -- to get off the ground, thereby running into worries (...) of circularity. (shrink)

Not quite killing it: black hole evaporation, global energy, and de-idealization.Eugene Y. S. Chua -2025 -European Journal for Philosophy of Science 15 (1):1-45.detailsA family of arguments for black hole evaporation relies on conservation laws, defined through symmetries represented by Killing vector fields which exist globally or asymptotically. However, these symmetries often rely on the idealizations of stationarity and asymptotic flatness, respectively. In non-stationary or non-asymptotically-flat spacetimes where realistic black holes evaporate, the requisite Killing fields typically do not exist. Can we ‘de-idealize’ these idealizations, and subsequently the associated arguments for black hole evaporation? Here, I critically examine the strategy of using ‘approximately Killing’ (...) fields to de-idealize black hole spacetimes and approximately extend conservation laws to non-idealized cases. I argue that this approach encounters significant challenges, undermining the use of these idealizations to justify the evaporation of realistic – rather than idealized – black holes, and raising questions about the justified use of such idealizations.

Degeneration and Entropy.Eugene Y. S.
