    The future of condition based monitoring: risks of operator removal on complex platforms.Marie Oldfield, Murray McMonies & Ella Haig - 2022 - AI and Society 2:1-12.
    Complex systems are difficult to manage, operate and maintain. This is why we see teams of highly specialised engineers in industries such as aerospace, nuclear and subsurface. Condition based monitoring is also employed to maximise the efficiency of extensive maintenance programmes instead of using periodic maintenance. A level of automation is often required in such complex engineering platforms in order to effectively and safely manage them. Advances in Artificial Intelligence related technologies have offered greater levels of automation but this potentially (...)

    Should Private Security Companies be Employed for Counterinsurgency Operations?David M. Barnes - 2013 - Journal of Military Ethics 12 (3):201-224.
    Many of the reasons offered for outsourcing security involve costs and benefits – a consequentialist way of reasoning. Thus, I will explore a consequentialist argument against the use of private security contractors (PSCs) in counterinsurgencies. Discussing the benefits and costs of employing PSCs in these kinds of operations will demonstrate that the hiring of PSCs in many cases (perhaps in most) is consequentially unsound. More precisely, the overall negative consequences of hiring PSCs during counterinsurgencies should preclude their use unless in (...)

    Is There a Just Cause for Current U.S. Military Operations in Afghanistan?John W. Lango - 2010 - International Journal of Applied Philosophy 24 (1):9-21.
    The current armed conflict in Afghanistan (briefly, the Afghan conflict) is viewed through the lens of a just war theory. In particular, the question stated by the title is explored by means of a generalized just cause principle. For brevity, empirical, practical, and legal issues about the Afghan conflict are mostly set aside. Hence a definite answer to the question is not proposed. Instead, the main aim is to clarify the question. Specifically, the question is amplified, by distinguishing putative just (...)

    Some restricted lindenbaum theorems equivalent to the axiom of choice.David W. Miller - 2007 - Logica Universalis 1 (1):183-199.
    . Dzik [2] gives a direct proof of the axiom of choice from the generalized Lindenbaum extension theorem LET. The converse is part of every decent logical education. Inspection of Dzik’s proof shows that its premise let attributes a very special version of the Lindenbaum extension property to a very special class of deductive systems, here called Dzik systems. The problem therefore arises of giving a direct proof, not using the axiom of choice, of the conditional . A partial solution (...)

    Logical Consequence Operators and Etatism.Wojciech Krysztofiak - 2020 - Studia Humana 9 (3-4):177-193.
    In the paper, there is presented the theory of logical consequence operators indexed with taboo functions. It describes the mechanisms of logical inference in the environment of forbidden sentences. This kind of processes take place in ideological discourses within which their participants create various narrative worlds (mental worlds). A peculiar feature of ideological discourses is their association with taboo structures of deduction which penalize speech acts. The development of discourse involves, among others, transforming its deduction structure towards the proliferation (...)

    Beyond Three Inferential Values.Grzegorz Malinowski - 2009 - Studia Logica 92 (2):203-213.
    The actual introduction of a non-reflexive and non-idempotent q -consequence gave birth to the concept of logical three-valuedness based on the idea of noncomplementary categories of rejection and acceptance. A q -consequence may not have bivalent description, the property claimed by Suszko’s Thesis on logical two-valuedness, ( ST ), of structural logics, i.e. structural consequence operations. Recall that ( ST ) shifts logical values over the set of matrix values and it refers to the division of matrix (...)

    In the paper, the authors discuss two kinds of consequence operations characterized axiomatically. The first one are consequence operations of the type Cn + that, in the intuitive sense, are infallible operations, always leading from accepted (true) sentences of a deductive system to accepted (true) sentences of the deductive system (see Tarski in Monatshefte für Mathematik und Physik 37:361–404, 1930, Comptes Rendus des Séances De la Société des Sciences et des Lettres de Varsovie 23:22–29, 1930; Pogorzelski and Słupecki (...)

    A Shared Framework for Consequence Operations and Abstract Model Theory.Christian Wallmann - 2013 - Logica Universalis 7 (2):125-145.
    In this paper we develop an abstract theory of adequacy. In the same way as the theory of consequence operations is a general theory of logic, this theory of adequacy is a general theory of the interactions and connections between consequence operations and its sound and complete semantics. Addition of axioms for the connectives of propositional logic to the basic axioms of consequence operations yields a unifying framework for different systems of classical propositional logic. We present an (...)

    The main theorem says that a consequence operator is an effective part of the consequence operator for the classical prepositional calculus iff it is a consequence operator for a logic satisfying the compactness theorem, and in which every finitely axiomatizable theory is decidable.

    Information algebras and consequence operators.Jürg Kohlas & Robert F. Stärk - 2007 - Logica Universalis 1 (1):139-165.
    . We explore a connection between different ways of representing information in computer science. We show that relational databases, modules, algebraic specifications and constraint systems all satisfy the same ten axioms. A commutative semigroup together with a lattice satisfying these axioms is then called an “information algebra”. We show that any compact consequence operator satisfying the interpolation and the deduction property induces an information algebra. Conversely, each finitary information algebra can be obtained from a consequence operator in this (...)

    This paper is a study of similarities and differences between strong and weak quantum consequence operations determined by a given class of ortholattices. We prove that the only strong orthologics which admits the deduction theorem (the only strong orthologics with algebraic semantics, the only equivalential strong orthologics, respectively) is the classical logic.

    The Rhetorical and Argumentative Relevance of "Extreme Consequence" in Advertising.Sabrina Mazzali-Lurati, Chiara Pollaroli & Daniela Marcantonio - 2019 - Informal Logic 39 (4):497-530.
    The “extreme consequence” is a very common pattern in advertising messages that presents an odd, even negative, situation resulting from the use of the advertised product as a good reason to buy it. By analyzing selected advertisements employing this pattern using the conceptual integration theory and the Argumentum Model of Topics, we aim to understand how “extreme consequence” works at the rhetorical and argumentative levels. The analyses allow us to detect the typical, generic, cognitive, and argumentative structure underlying (...)

    A characterization of consequence operations preserving degrees of truth.Marek Nowak - 1987 - Bulletin of the Section of Logic 16 (4):159-165.
    Formalization of reasoning which accepts rules of inference leading to conclusions whose logical values are not smaller than the logical value of the “weakest” premise leads to the concept of consequence operation preserving degrees of truth. Several examples of such consequence operation have already been considered . In the present paper we give a general notion of the consequence operation preserving degrees of truth and its characterization in terms of projective generation and selfextensionality.

    General logic-systems and finite consequence operators.Robert A. Herrmann - 2007 - Logica Universalis 1 (1):201-208.
    . In this paper, the significance of using general logic-systems and finite consequence operators defined on non-organized languages is discussed. Results are established that show how properties of finite consequence operators are independent from language organization and that, in some cases, they depend only upon one simple language characteristic. For example, it is shown that there are infinitely many finite consequence operators defined on any non-organized infinite language L that cannot be generated from any finite logic-system. On (...)

    Tarski’s papers, in which he examines the idea of a consequence operation Cn,divide into two groups. One of them is formed by the papers that offer an analysis of the general idea of the consequence operation. Resorting to fundamental ideas of logical semantics, Tarski explains what, in his view, it means to say that a formula a of a language L is a logical consequence Cn of a set of formulas X of that language.

    The lattice of strengthenings of a strongly finite consequence operation.Wiesław Dziobiak - 1981 - Studia Logica 40 (2):177 - 193.
    First, we prove that the lattice of all structural strengthenings of a given strongly finite consequence operation is both atomic and coatomic, it has finitely many atoms and coatoms, each coatom is strongly finite but atoms are not of this kind — we settle this by constructing a suitable counterexample. Second, we deal with the notions of hereditary: algebraicness, strong finitisticity and finite approximability of a strongly finite consequence operation. Third, we formulate some conditions which tell (...)

    In the present paper, we study some properties of matrices for non-structural consequence operators. These matrices were introduced in a former work (see [3]). In sections 1. and 2., general definitions and theorems are recalled; in section 3. a correspondence is studied, among our matrices and Wójcicki's ones for structural operators. In section 4. a theorem is given about operators, induced by submatrices or epimorphic images, or quotient matrices of a given one.Such matrices are used to characterize lattices of (...)

    In this paper we investigate the relation between the axiomatization of a given logical consequence operation and axiom systems defining the class of algebras related to that consequence operation. We show examples which prove that, in general there are no natural relation between both ways of axiomatization.

    In this paper we dene a concept of depth of a consequence operation which seems to have a few useful properties. To make our denition worth- while we shall show that the concept of depth leads to a strengthening of the well-known theorem of R. Wojcicki [4]. For unexplained terminology and notations we refer the reader to R. Wojcicki [5].

    Prescribing meaning: hedonistic perspectives on the therapeutic use of psychedelic-assisted meaning enhancement.Riccardo Miceli McMillan - 2021 - Journal of Medical Ethics 47 (10):701-705.
    The recent renaissance in research on psychedelic-assisted psychotherapy is showing great promise for the treatment of many psychiatric conditions. Interestingly, therapeutic outcomes for patients undergoing these treatments are predicted by the occurrence of a mystical experience—an experience characterised in part by a sense of profound meaning. This has led to hypotheses that psychedelic-assisted psychotherapy is therapeutic because it enhances perception of meaning, and consequently leads to a meaning response. The putative mechanism of action of psychedelics as meaning enhancers raises normative (...)

    Origin of life models based on “energized assemblages of building blocks” are untenable in principle. This is fundamentally a consequence of the fact that any living system is in a physical state that is extremely far from equilibrium, a condition it must itself build and sustain. This in turn requires that it carries out all of its molecular transformations–obligatorily those that convert, and thereby create, disequilibria–using case‐specific mechanochemical macromolecular machines. Mass‐action solution chemistry is quite unable to do this. We (...)

    This chapter explores the consequence of taking Rawls' concerns about the strains of commitment to their logical extreme. If there is no external enforcement at all, so that all agreements must be self-policing, it is shown that deals reached in the original position will generate an egalitarian outcome, as Rawls would wish. The conclusions are broadly consistent with the class of laboratory results that psychologists refer to as “modern equity theory”. The concept of an empathy equilibrium is used to (...)

Um espaço de Tarski é um par ordenado determinado por um conjunto não vazio e um operador de consequência sobre este conjunto. Esta estrutura matemática caracteriza um espaço quase topológico. Este artigo mostra uma visão algébrica dos espaços de Tarski e introduz uma lógica proposicional modal que interpreta o seu operador modal nos conjuntos fechados de algum espaço de Tarski.

    A Novel Image Encryption Scheme Based on PWLCM and Standard Map.Yucheng Chen, Chunming Tang & Zongxiang Yi - 2020 - Complexity 2020:1-23.
    In the past decades, considerable attention has been paid to the chaos-based image encryption schemes owing to their characteristics such as extreme sensitivity to initial conditions and parameters, pseudo-randomness, and unpredictability. However, some schemes have been proven to be insecure due to using a single chaotic system. To increase the security, this work proposes a novel image encryption scheme based on the piecewise linear chaotic map and the standard map. To the best of our knowledge, it is the first chaos-based (...)
