    Strongly Amorphous Sets and Dual Dedekind Infinity.Martin Goldstern - 1997 - Mathematical Logic Quarterly 43 (1):39-44.
    1. If A is strongly amorphous , then its power set P is dually Dedekind infinite, i. e., every function from P onto P is injective. 2. The class of “inexhaustible” sets is not closed under supersets unless AC holds.

    The structure of amorphous sets.J. K. Truss - 1995 - Annals of Pure and Applied Logic 73 (2):191-233.
    A set is said to be amorphous if it is infinite, but is not the disjoint union of two infinite subsets. Thus amorphous sets can exist only if the axiom of choice is false. We give a general study of the structure which an amorphous set can carry, with the object of eventually obtaining a complete classification. The principal types of amorphous set we distinguish are the following: amorphous sets not of projective type, (...)

    On o-amorphous sets.P. Creed & J. K. Truss - 2000 - Annals of Pure and Applied Logic 101 (2-3):185-226.
    We study a notion of ‘o-amorphous’ which bears the same relationship to ‘o-minimal’ as ‘amorphous’ 191–233) does to ‘strongly minimal’. A linearly ordered set is said to be o-amorphous if its only subsets are finite unions of intervals. This turns out to be a relatively straightforward case, and we can provide a complete ‘classification’, subject to the same provisos as in Truss . The reason is that since o-amorphous is an essentially second-order notion, it corresponds more (...)

    On quasi-amorphous sets.P. Creed & J. K. Truss - 2001 - Archive for Mathematical Logic 40 (8):581-596.
    A set is said to be amorphous if it is infinite, but cannot be written as the disjoint union of two infinite sets. The possible structures which an amorphous set can carry were discussed in [5]. Here we study an analogous notion at the next level up, that is to say replacing finite/infinite by countable/uncountable, saying that a set is quasi-amorphous if it is uncountable, but is not the disjoint union of two uncountable sets, and (...)

    A notion of rank in set theory without choice.G. S. Mendick & J. K. Truss - 2003 - Archive for Mathematical Logic 42 (2):165-178.
    Starting from the definition of `amorphous set' in set theory without the axiom of choice, we propose a notion of rank (which will only make sense for, at most, the class of Dedekind finite sets), which is intended to be an analogue in this situation of Morley rank in model theory.

    Exclusion Principles as Restricted Permutation Symmetries.S. Tarzi - 2003 - Foundations of Physics 33 (6):955-979.
    We give a derivation of exclusion principles for the elementary particles of the standard model, using simple mathematical principles arising from a set theory of identical particles. We apply the theory of permutation group actions, stating some theorems which are proven elsewhere, and interpreting the results as a heuristic derivation of Pauli's Exclusion Principle (PEP) which dictates the formation of elements in the periodic table and the stability of matter, and also a derivation of quark confinement. We arrive at these (...)

    Theory can be more than it used to be: learning anthropology's method in a time of transition.Dominic Boyer, James D. Faubion & George E. Marcus (eds.) - 2015 - London: Cornell University Press.
    Within anthropology, as elsewhere in the human sciences, there is a tendency to divide knowledge making into two separate poles: conceptual (theory) vs. empirical (ethnography). In Theory Can Be More than It Used to Be, Dominic Boyer, James D. Faubion, and George E. Marcus argue that we need to take a step back from the assumption that we know what theory is to investigate how theory—a matter of concepts, of analytic practice, of medium of value, of professional ideology—operates in anthropology (...)

  9. What is the Harm Principle For?John Stanton-Ife - 2016 - Criminal Law and Philosophy 10 (2):329-353.
    In their excellent monograph, Crimes, Harms and Wrongs, Andrew Simester and Andreas von Hirsch argue for an account of legitimate criminalisation based on wrongfulness, the Harm Principle and the Offence Principle, while they reject an independent anti-paternalism principle. To put it at its simplest my aim in the present paper is to examine the relationship between ‘the harms’ and ‘the wrongs’ of the authors’ title. I begin by comparing the authors’ version of the Harm and Offence Principle with some other (...)

    It is shown that in ZF Martin's -axiom together with the axiom of countable choice for finite sets imply that arbitrary powers 2X of a 2-point discrete space are Baire; and that the latter property implies the following: (a) the axiom of countable choice for finite sets, (b) power sets of infinite sets are Dedekind-infinite, (c) there are no amorphous sets, and (d) weak forms of the Kinna-Wagner principle.

    The patient perspective in health care networks.Kasper Raus, Eric Mortier & Kristof Eeckloo - 2018 - BMC Medical Ethics 19 (1):52.
    Health care organization is entering a new age. Focus is increasingly shifting from individual health care institutions to interorganizational collaboration and health care networks. Much hope is set on such networks which have been argued to improve economic efficiency and quality of care. However, this does not automatically mean they are always ethically justified. A relevant question that remains is what ethical obligations or duties one can ascribe to these networks especially because networks involve many risks. Due to their often (...)

    Intelligibility and conflict resolution in the lifeworld.Barbara Fultner - 2001 - Continental Philosophy Review 34 (4):419-436.
    This paper examines the role of Habermas's concept of the lifeworld in processes of reaching mutual understanding. This concept is shown to be ultimately too amorphous to bear the theoretical weight Habermas places on it. He conceives the lifeworld both as diffuse and holistic, yet also as structured; as a set of taken-for-granted and counterfactual presuppositions, yet also as a kind of knowledge. In the end, he presupposes what the lifeworld is supposed to explain: mutual intelligibility of subjects in (...)

  15. Aristotle on Epigenesis.Devin Henry - 2018
    It has become somewhat of a platitude to call Aristotle the first epigenesist insofar as he thought form and structure emerged gradually from an unorganized, amorphous embryo. But modern biology now recognizes two senses of “epigenesis”. The first is this more familiar idea about the gradual emergence of form and structure, which is traditionally opposed to the idea of preformationism. But modern biologists also use “epigenesis” to emphasize the context-dependency of the process itself. Used in this sense development is (...)

    “Artworks are not being but a process of becoming” —Theodor W. Adorno, Aesthetic Theory In the everyday use of the concept, saying that something is grotesque rarely implies anything other than saying that something is a bit outside of the normal structure of language or meaning – that something is a peculiarity. But in its historical use the concept has often had more far reaching connotations. In different phases of history the grotesque has manifested its forms as a means of (...)

    Understanding the Resistive Switching Phenomena of Stacked Al/Al2O3/Al Thin Films from the Dynamics of Conductive Filaments. [REVIEW]Joel Molina-Reyes & Luis Hernandez-Martinez - 2017 - Complexity:1-10.
    We present the resistive switching characteristics of Metal-Insulator-Metal devices based on amorphous Al2O3which is deposited by Atomic Layer Deposition. A maximum processing temperature for this memory device is 300°C, making it ideal for Back-End-of-Line processing. Although some variations in the forming, set, and reset voltages are obtained for many of the measured MIM devices, thememristoreffect has been obtained after cyclicI-Vmeasurements. These resistive transitions in the metal oxide occur for bothbipolarandunipolarconditions, while theIOFF/IONratio is around 4–6 orders of magnitude and is (...)

  19. Who Decides How History Should Be Studied? [REVIEW]Vicente Medina - 2022 - Chronicle of Higher Education 69 (2):1-1.
    The claim that historians “write from a present-day perspective” does not entail that the past only matters when interpreted by categories of social justice. The past is a set of amorphous events and people, including their actions and motives. So, historians are free to explore various aspects of it to offer meaningful and compelling interpretations without necessarily privileging one category. The past is richer than we can humanely understand. Hence, it is important that new generations of scholars revise it (...)

    Reflecting stationary sets and successors of singular cardinals.Saharon Shelah - 1991 - Archive for Mathematical Logic 31 (1):25-53.
    REF is the statement that every stationary subset of a cardinal reflects, unless it fails to do so for a trivial reason. The main theorem, presented in Sect. 0, is that under suitable assumptions it is consistent that REF and there is a κ which is κ+n -supercompact. The main concepts defined in Sect. 1 are PT, which is a certain statement about the existence of transversals, and the “bad” stationary set. It is shown that supercompactness (and even the failure (...)

(This completes results of Baumgartner and Harrington and Shelah.)

    Sets, Set Sizes, and Infinity in Badiou's Being and Event.Tzuchien Tho - 2020 - Filozofski Vestnik 41 (2).
    This paper argues that Cantorian transfinite cardinality is not a necessary assumption for the ontological claims in Badiou’s L’Être et l’Événement (Vol. 1). The necessary structure for Badiou’s mathematical ontology in this work was only the ordinality of sets. The method for reckoning the sizes of sets was only assumed to follow the standard Cantorian measure. In the face of different and compelling forms of measuring non-finite sets (following Benci and Di Nasso, and Mancosu), it is argued (...)

    Forcing with adequate sets of models as side conditions.John Krueger - 2017 - Mathematical Logic Quarterly 63 (1-2):124-149.
    We present a general framework for forcing on ω2 with finite conditions using countable models as side conditions. This framework is based on a method of comparing countable models as being membership related up to a large initial segment. We give several examples of this type of forcing, including adding a function on ω2, adding a nonreflecting stationary subset of, and adding an ω1‐Kurepa tree.

    What Really Sets the Upper Bound on Quantum Correlations?Joy Christian - unknown
    The discipline of parallelization in the manifold of all possible measurement results is shown to be responsible for the existence of all quantum correlations, with the upper bound on their strength stemming from the maximum of possible torsion within all norm-composing parallelizable manifolds. A profound interplay is thus uncovered between the existence and strength of quantum correlations and the parallelizability of the spheres S^0, S^1, S^3, and S^7 necessitated by the four real division algebras. In particular, parallelization within a unit (...)

    Regularity properties for dominating projective sets.Jörg Brendle, Greg Hjorth & Otmar Spinas - 1995 - Annals of Pure and Applied Logic 72 (3):291-307.
    We show that every dominating analytic set in the Baire space has a dominating closed subset. This improves a theorem of Spinas [15] saying that every dominating analytic set contains the branches of a uniform tree, i.e. a superperfect tree with the property that for every splitnode all the successor splitnodes have the same length. In [15], a subset of the Baire space is called u-regular if either it is not dominating or it contains the branches of a uniform tree, (...)

    Bipolar Soft Sets: Relations between Them and Ordinary Points and Their Applications.Tareq M. Al-Shami - 2021 - Complexity 2021:1-14.
    Bipolar soft set is formulated by two soft sets; one of them provides us the positive information and the other provides us the negative information. The philosophy of bipolarity is that human judgment is based on two sides, positive and negative, and we choose the one which is stronger. In this paper, we introduce novel belong and nonbelong relations between a bipolar soft set and an ordinary point. These relations are considered as one of the unique characteristics of bipolar (...)

    Crypto-preorders, topological relations, information and logic.Piero Pagliani International Rough Set Society, Rome & Italy - 2024 - Journal of Applied Non-Classical Logics 34 (2):330-367.
    As is well known, any preorder R on a set U induces an Alexandrov topology on U. In some interesting cases related to data mining an Alexandrov topology can be transformed into different types of logico-algebraic models. In some cases, (pre)topological operators provided by Pointless Topology may define a topological space on U even if R is not a preorder. If this is the case, then we call R a crypto-preorder. The paper studies the conditions under which a relation R (...)

    On Subcreative Sets and S-Reducibility.John T. Gill Iii & Paul H. Morris - 1974 - Journal of Symbolic Logic 39 (4):669 - 677.
    Subcreative sets, introduced by Blum, are known to coincide with the effectively speedable sets. Subcreative sets are shown to be the complete sets with respect to S-reducibility, a special case of Turing reducibility. Thus a set is effectively speedable exactly when it contains the solution to the halting problem in an easily decodable form. Several characterizations of subcreative sets are given, including the solution of an open problem of Blum, and are used to locate the (...)

    Core information sets for informed consent to surgical interventions: baseline information of importance to patients and clinicians.Barry G. Main, Angus G. K. McNair, Richard Huxtable, Jenny L. Donovan, Steven J. Thomas, Paul Kinnersley & Jane M. Blazeby - 2017 - BMC Medical Ethics 18 (1):29.
    Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient’s values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge (...)

    Effectively closed sets of measures and randomness.Jan Reimann - 2008 - Annals of Pure and Applied Logic 156 (1):170-182.
    We show that if a real x2ω is strongly Hausdorff -random, where h is a dimension function corresponding to a convex order, then it is also random for a continuous probability measure μ such that the μ-measure of the basic open cylinders shrinks according to h. The proof uses a new method to construct measures, based on effective continuous transformations and a basis theorem for -classes applied to closed sets of probability measures. We use the main result to derive (...)
