Representation of quantum states by statistical ensembles on the quantum phase space in the Hamiltonian form of quantum mechanics is analyzed. Various mathematical properties and some physical interpretations of the equivalence classes of ensembles representing a mixed quantum state in the Hamiltonian formulation are examined. In particular, non-uniqueness of the quantum phase space probability density associated with the quantum mixed state, Liouville dynamics of the probability densities and the possibility to represent the reduced states of bipartite systems by marginal distributions (...) are discussed in detail. These considerations are used to study ensembles of hybrid quantum-classical systems. In particular, nonlinear evolution of a single hybrid system in a pure state and unequal evolutions of initially equivalent ensembles are discussed in the context of coupled hybrid systems. (shrink)

This essay reviews six different approaches to intellectual property. It and argues that none of these accounts provide an adequate justification of intellectual property laws and policies because (1) there are many different types of intellectual property, and (2) a variety of incommensurable values play a role in the justification of intellectual property. The best approach to intellectual property is to assess and balance competing moral values in light of the particular facts and circumstances.

This essay develops a framework for thinking about the moral basis for the commodification of human reproductive materials. It argues that selling and buying gametes and genes is morally acceptable although there should not be a market for zygotes, embryos, or genomes. Also a market in gametes and genes should be regulated in order to address concerns about the adverse social consequences of commodification.

The phrase “minimal risk,” as defined in the United States’ federal research regulations, is ambiguous and poorly defined. This article argues that most of the ambiguity that one finds in the phrase stems from the “daily life risks” standard in the definition of minimal risk. In this article, the author argues that the daily life risks standard should be dropped and that “minimal risk” should be defined as simply “the probability and magnitude of the harm or discomfort anticipated in research (...) are not greater than those encountered during the performance of routine physical or psychological examinations or tests”.

Inappropriate authorship is a common problem in biomedical research and may be becoming one in bioethics, due to the increase in multiple authorship. This paper investigates the authorship policies of bioethics journals to determine whether they provide adequate guidance for researchers who submit articles for publication, which can help deter inappropriate authorship. It was found that 63.3% of bioethics journals provide no guidance on authorship; 36.7% provide guidance on which contributions merit authorship, 23.3% provide guidance on which contributions do not (...) merit authorship, 23.3% require authors to take responsibility for their contributions or for the article as a whole, 20% provide guidance on which contributions merit an acknowledgement but not authorship, 6.7% require authors to describe their contributions, and only 3.3% distinguish between authorship in empirical and conceptual research. To provide authors with effective guidance and promote integrity in bioethics research, bioethics journals should adopt authorship policies that address several important topics, such as the qualifications for authorship, describing authorship contributions, taking responsibility for the research and the difference between authorship in empirical and conceptual research.

Informed consent is one of the foundational ethical and legal requirements of research with human subjects. The Nuremberg Code, the Helsinki Declaration, the Belmont Report, the Common Rule and many other laws and codes require that research subjects make a voluntary, informed choice to participate in research.12345 Informed consent is based on the moral principle of respect for autonomy, which holds that rational individuals have a right to make decisions and take actions that reflect their values and preferences. 6 Whereas (...) most guidelines and codes also require that informed consent be properly documented, informed consent is much more than signing a piece of paper: It is a continuous process of communication between the investigator and the research subject. 7 Because the body of knowledge impacting a study frequently changes, subjects should receive information from investigators after they have enrolled in a study, such as significant new findings that may affect their decision to participate in research or clinically useful tests results. 8910 In large studies, some investigators use newsletters to update subjects on the progress of research and other developments.11Most of the ongoing communications between investigators and subjects involve little more than information sharing, without revisiting the decision to participate in research or signing any additional documents. Sometimes, however, it may be necessary for subjects to reaffirm their decision to participate, to re-consent, or to sign or re-sign a document. 8 Re-consent can be defined as an action in which a subject makes the decision to participate in research once again. Re-consent is different from reaffirming a commitment to participate in a study, because in re-consent one actually reconsiders the information necessary to make decision, whereas in reaffirmation one simply expresses ….

We construct all cosmic field tensors which are symmetric rank-two tensor concomitants of a metric and a background metric and which have zero divergence when the background metric satisfies the generalized De Donder condition. The resulting background cosmic field represents an Einstein space-time.

Susan Schneider (2019) has proposed two new tests for consciousness in AI (artificial intelligence) systems, the AI Consciousness Test and the Chip Test. On their face, the two tests seem to have the virtue of proving satisfactory to a wide range of consciousness theorists holding divergent theoretical positions, rather than narrowly relying on the truth of any particular theory of consciousness. Unfortunately, both tests are undermined in having an ‘audience problem’: Those theorists with the kind of architectural worries that motivate (...) the need for such tests should, on similar grounds, doubt that the tests establish the existence of genuine consciousness in the AI in question. Nonetheless, the proposed tests constitute progress, as they could find use by some theorists holding fitting views about consciousness and perhaps in conjunction with other tests for AI consciousness.

The concept of hysteria is traced from Hippocrates, where it was thought to be caused by a wandering uterus, through Galen and up to Freud. Throughout the history of medicine from the early Greeks up to the end of the nineteenth century, the definition and diagnosis of hysteria had a function similar to that found in the persecution of witchcraft: it sought to eradicate the outbursts of nonconforming and emotionally threatening conduct of women. At the beginning of the twentieth century, (...) however, the category virtually disappears from psychiatric nosologies. (shrink)

This book focuses on the mind and its ability to seek answers to unknown or unanswered questions. The theory of educating provides the grounding for using V diagrams by students, educators, researchers, and parents. Teachers make lesson plans using V diagrams and concept maps. They become expert coaches in guiding student performances. Students learn to construct their own knowledge. They change from question-answerers to question-askers. Parents share meaning with their children and their children's teachers and administrators. Administrators monitor programs and (...) are in touch with all participants in schools and universities. Researchers and evaluators can share records of events and facts. With this theory working in the classrooms and laboratories of many practical places of educating plus extending into the world of technology literacy, The Art of Educating with V Diagrams explains how educating works.

Mr. Kubat attributes much of the misinformation about Brentano's theories to the lack of an edition of Brentano's collected writing. If anyone should wish to know more about Brentano's doctrines, he may have been led by this remark to despair of finding them anywhere in print. The three works which Mr. Kubat mentions, Grundlegung und Aufbau der Ethik, Religion und Philosophie, and Die Lehre vom richtigen Urteil, all edited by F. Mayer-Hillebrand and published by A. Francke in Bern, represent no (...) more than a continuation of the Gesamtausgabe of Brentano's writings which was begun by Oskar Kraus and Alfred Kastil after Brentano's death. The volumes in the Gesamtausgabe represent ten numbers in Meiner's Philosophische Bibliothek and are listed under the heading, "Gesammelte philosophische Schriften." They contain not only new editions of much of the work which Brentano published during his lifetime, but a large amount of material which Kraus and Kastil selected from his enormous Nachlass as well. I am sure that Mrs. Mayer-Hillebrand herself would be the first to recognize that the three published volumes she has edited, and the one on esthetics which is soon to appear in print, are part of a whole which also includes the volumes edited by Kraus and Kastil. Taken altogether, the thirteen volumes that have been published by Meiner and by Francke can well be viewed as at least an adequate substitute for a collected edition. Surely they include everything which is necessary to dispel the common misinformation which Mr. Kubat tries to explain by denying their existence. The trouble has not been the lack of a collected edition, but the lack of readers. (shrink)
