Thomas Reid in the eighteenth century and Ludwig Wittgenstein in the twentieth made strong cases for the existence of "communication systems" that must be in place if there is to be the acquisition of any language; language in the full sense of a system of words, displaying distinctions into word classes and ordered by a grammar that is sensitive to those word classes. Although their pre-languages have something of the character of language proper, Reid and Wittgenstein offer a very different (...) conception of the necessary conditions for the existence of language from that proposed by Chomsky, much criticized for its implausible cognitivism. In this paper we compare and contrast Reidian and Wittgensteinian conceptions of what there must be for language to be possible, and draw some morals for the vexed, but in our view, empty question of the demarcation of language from all other intentional and normative systems in use amongst people and animals.

A discussion of one of the three books by which McCloskey launched his own economic rhetoric. The main criticism is that McCloskey enlarged view of rhetoric is still not encompassing enough, being limited to rhetoric in the writing of economic literature, while leaving the function of metaphor and other tropes in the more basic processes of conceptualization, theory change, and construction of 'observed' phenomena.
The present paper introduces and studies the variety [MATHEMATICAL SCRIPT CAPITAL W]ℋn of n-linear weakly Heyting algebras. It corresponds to the algebraic semantic of the strict implication fragment of the normal modal logic K with a generalization of the axiom that defines the linear intuitionistic logic or Dummett logic. Special attention is given to the variety [MATHEMATICAL SCRIPT CAPITAL W]ℋ2 that generalizes the linear Heyting algebras studied in [10] and [12], and the linear Basic algebras introduced in [2].
I discuss the interpretation of the principle of utility as a factual statement, the relevance of Halévy's interetation of Bentham, and then Bentham's relationship with James Mill and David Ricardo.
In this paper we shall introduce the variety FWHA of frontal weak Heyting algebras as a generalization of the frontal Heyting algebras introduced by Leo Esakia in [10]. A frontal operator in a weak Heyting algebra A is an expansive operator r preserving finite meets which also satisfies the equation?? b V, for all a,b? A. These operators were studied from an algebraic, logical and topological point of view by Leo Esakia in [10]. We will study frontal operators in weak (...) Heyting algebras and we will consider two examples of them. We will give a Priestley duality for the category of frontal weak Heyting algebras in terms of relational spaces where is a WH space [6], and R is an additional binary relation used to interpret the modal operator. We will also study the WH- algebras with successor and the WTf- algebras with gamma. For these varieties we will give two topological dualities. The first one is based on the representation given for the frontal weak Heyting algebras. The second one is based on certain particular classes of WH-spaces. (shrink)
Virtually all the major scholarly reference works, as well as many more popular sources, provide two alternative versions of the ancestry of Amphictyon, the mythical founder of the Delphic-Pylaic amphictyony, as either the son or the grandson of Deucalion, that is, by implication, either the brother or the son of Hellen. Yet, a review of all relevant sources shows that they unanimously and exclusively refer to Amphictyon as the son of Deucalion.
Identity, Morality, and Threat offers a critical examination of the social psychological processes that generate outgroup devaluation and ingroup glorification as the source of conflict. Daniel Rothbart and Karyna Korostelina bring together essays analyzing the causal relationship between escalating violence and opposing images of the Self and Other.

. The uniform prior distribution is often seen as a mathematical description of noninformativeness. This paper uses the well-known Three Prisoners Paradox to examine the impossibility of maintaining noninformativeness throughout hierarchization. The Paradox has been solved by Bayesian conditioning over the choice made by the Warder when asked to name a prisoner who will be shot. We generalize the paradox to situations of N prisoners, k executions and m announcements made by the Warder. We then extend the consequences of hierarchically (...) placing uniform and symmetrical priors for the probability p of the Warder naming Prisoner B, say. We prove that breaks of indifference and neutrality caused by assignment of uniform and symmetrical priors in lieu of degenerate indifference probabilities hold in general. Speaking of unknown probabilities or of probability of a probability must be forbidden as meaningless.

The paper studies two formal schemes related to -completeness.LetS be a suitable formal theory containing primitive recursive arithmetic and letT be a formal extension ofS. Denoted by (a), (b) and (c), respectively, are the following three propositions (where (x) is a formula with the only free variable x): (a) (for anyn) ( T (n)), (b) T x Pr T (–(x)–) and (c) T x(x) (the notational conventions are those of Smoryski [3]). The aim of this paper is to examine the (...) meaning of the schemes which result from the formalizations, over the base theoryS, of the implications (b) (c) and (a) (b), where ranges over all formulae. The analysis yields two results overS : 1. the schema corresponding to (b) (c) is equivalent to ¬Cons T and 2. the schema corresponding to (a) (b) is not consistent with 1-CON T. The former result follows from a simple adaptation of the -incompleteness proof; the second is new and is based on a particular application of the diagonalization lemma. (shrink)
The traditional ontology within which chemistry has developed involved various versions of a general substance/attribute scheme. Recently this has been challenged by two versions of Dynamism. One version is derived from the writings of A. N. Whitehead and the other from several sources, including G. Leibniz and I. Kant. Both involve the idea of flux of actual occasions. Unlike the former scheme, the latter involves a foundation of causal powers and the energetics of field theory. The situation has been made (...) more interesting because of the revival of trope theory, based on an ontology of particularized attributes. This notion is claimed to resolve philosophical problems about the nature of universals and of substances through the introduction of spatial and temporal sequences of tropes. While trope theory seems, at first sight, to work as an attractive alternative to substance/attribute close inspection shows that it is beset with difficulties that are more problematic that the dynamist ontology based on casual powers, dispositions and affordances.

In this paper we shall introduce the variety WQS of weak-quasi-Stone algebras as a generalization of the variety QS of quasi-Stone algebras introduced in [9]. We shall apply the Priestley duality developed in [4] for the variety N of ¬-lattices to give a duality for WQS. We prove that a weak-quasi-Stone algebra is characterized by a property of the set of its regular elements, as well by mean of some principal lattice congruences. We will also determine the simple and subdirectly (...) irreducible algebras. (shrink)

A short discussion of the origin of the notion of mode of subsistence in the eighteenth-century discussion and particularly in the Scottish Enlightenment and its legacy n the Marxist theory of modes of production or social economic formations.
Does self-control require willpower? The question cuts to the heart of a debate about whether self-control is identical with some psychological process internal to the agents or not. Noticeably absent from these debates is systematic evidence about the folk-psychological category of self-control. Here, we present the results of two behavioral studies (N = 296) that indicate the structure of everyday thinking about self-control. In Study 1, participants rated the degree to which different strategies to respond to motivational conflict exemplify self-control. (...) Participants distinguished between intra-psychic and externally-scaffolded strategies and judged that the former exemplified self-control more than the latter. In Study 2, participants provided various solutions to manage motivational conflict and rated their proposals on effectiveness. Participants produced substantially more intra-psychic strategies, rated them as more effective, and advised them at a higher rate than externally-scaffolded strategies. Taken together, these results suggest that while people recognize a plurality of strategies as genuine instances of self-control, purely internal exercises of self-control are considered more prototypical than their externally-scaffolded counterparts. This implies a hierarchical structure for the folk psychological category of self-control. The concept encompasses a variety of regulatory strategies and organizes these strategies along a hierarchical continuum, with purely intra-psychic strategies at the center and scaffolded strategies in the periphery.

The study investigated the influence of resilience and dispositional optimism on, first, emotional distress and, second, the intention to self-isolate, experienced by people with a lower and higher illness risk, during the lockdown imposed in Spain during the first COVID-19 wave. These effects were investigated against the background of the Health Belief Model. A convenience sample of N = 325 participants completed an online survey including an ad-hoc questionnaire measuring the HBM core factors: Perceived health threat, and perceived quarantine benefits (...) and costs. Self-efficacy and perceived social pressure were also measured. Based on reviews regarding pandemic outbreaks, quarantine benefits were conceptualized as the perceived effectiveness and solidary contribution of self-isolating in line with the quarantine protocols. Quarantine “psychosocial” costs were conceptualized as a composite of perceived boredom, loneliness, and economic concerns. Findings revealed an asymmetrical pattern of results so that people at higher risk were more distressed by the perceived severity of getting infected whereas people at lower risk were more distressed by the psychosocial costs. Moreover, resilience and optimism were more “protective” against distress within the lower and higher risk groups, respectively. In addition, quarantine benefits and self-efficacy promoted the intention to self-isolate within both groups. However, optimism hindered such intention. This finding is discussed in the light of links between dispositional optimism and optimistic bias; the underestimation of experiencing negative events, which can relax the perceived health risk. Based on these findings, communication campaigns should prioritize information about the effectiveness of the implemented preventive behaviors rather than the costs of not implementing them, and be cautionary in encouraging excessive optimism.

Lower extremity non-contact soft tissue injuries are prevalent in elite futsal. The purpose of this study was to develop robust screening models based on pre-season measures obtained from questionnaires and field-based tests to prospectively predict LE-ST injuries after having applied a range of supervised Machine Learning techniques. One hundred and thirty-nine elite futsal players underwent a pre-season screening evaluation that included individual characteristics; measures related to sleep quality, athlete burnout, psychological characteristics related to sport performance and self-reported perception of chronic (...) ankle instability. A number of neuromuscular performance measures obtained through three field-based tests [isometric hip strength, dynamic postural control and lower extremity joints range of motion ] were also recorded. Injury incidence was monitored over one competitive season. There were 25 LE-ST injuries. Only those groups of measures from two of the field-based tests, as independent data sets, were able to build robust models [area under the receiver operating characteristic curve score ≥0.7] to identify elite futsal players at risk of sustaining a LE-ST injury. Unlike the measures obtained from the five questionnaires selected, the neuromuscular performance measures did build robust prediction models. The inclusion in the same data set of the measures recorded from all the questionnaires and field-based tests did not result in models with significantly higher performance scores. The model generated by the UnderBagging technique with a cost-sensitive SMO as the base classifier and using only four ROM measures reported the best prediction performance scores. The models developed might help coaches, physical trainers and medical practitioners in the decision-making process for injury prevention in futsal. (shrink)
Nach dem ersten Band dieser Sammlung , von S. N. C. Lieu und M. H. Dodgeon zusammengestellt, hat der vorliegende Band Informationen zu den Beziehungen zwischen Rom/ Byzanz und den persischen Sasaniden bis unmittelbar vor der arabischen Eroberung Irans zum Gegenstand. Zusammen mit der etwas anders konzipierten Arbeit von E. Winter und B. Dignas verfügen wir nun über drei griffige Hilfsmittel für den Anfängerunterricht, die es uns ermöglichen, die Studenten schnell in die persisch-römisch/byzantinischen Beziehungen zwischen dem 3. und dem frühen (...) 7. Jh. auf der Grundlage einer breiten Quellenübersicht einzuführen. Dafür gebührt den Autoren Anerkennung. Ihre Arbeit wird sicher dazu beitragen, auch nicht direkt mit dem Thema Beschäftigte ein etwas qualifiziertes Verständnis der „Weltpolitik“ zwischen dem 3.und dem 7. Jh. zu ermöglichen. Alle drei Werke sind Lehrbücher, textbooks, jedoch keine wissenschaftlichen Arbeiten im eigentlichen Sinne. (shrink)
