The purpose of this article is to introduce a class of distance-based iterated revision operators generated by minimizing the geodesic distance on a graph. Such operators correspond bijectively to metrics and have a simple finite presentation. As distance is generated by distinguishability, our framework is appropriate for modelling contexts where distance is generated by threshold, and therefore, when measurement is erroneous.

Tolerance spaces are sets equipped with a reflexive, symmetric, but not necessarily transitive, relation of indistinguishability, and are useful for describing vagueness based on error-prone measurements. We show that any tolerance space can be embedded in one generated by comparisons using prototypical objects. As a result propositions, definable on a tolerance space can be translated into propositions behaving classically.

This article foregrounds an unofficial, “dark” strand of shamanic revival, which lies at the interstices of local inspirational religion and the state’s law in a Siberian periphery. Focusing on consultations concerned with ritual healing and counter-cursing in the Russian Republic of Tuva/tyva, southern Siberia, the article documents a field of metaphysical disorder which is governed by shamans as purveyors of “forensic” evidence of cursing and as arbiters of justice. The data on counter-cursing consultations evince a social perception of shamanism as (...) a redress for kinds of violence which transcend the limits of state law. Drawing on two shamanic narratives of affliction and its professionalization as a charisma for healing and revenge respectively, the article argues that a new kind of “forensic” evidence of crime and violence emerges from the materials on counter-cursing in Kyzyl.

Over every and each sport event, a dark veil spreads and obfuscates the celebration: doping. Although anti-doping policies have been widely applied, controlling and diminishing this phenomenon has not been achieved yet and the use of doping is commonplace. In this article, I propose the concept of narcissistic civilization as a tool to interpret this phenomenon. I seek for a parallel reading between the Freudian idea of narcissism and its extension to social narcissism by Fromm, together with Heidegger’s analysis of (...) technology, keeping in mind that doping is a technological application. In this way I point out that both theories share a common view in that humans tend to fail in the distinction between the external reality as an object and their own self as the interpreter, that is between the ¨I¨ and the ¨not I¨. By making this fusion of the two theories that originate from different intellectual traditions, I aspire to provide an interpretation tool for the broad use of doping: I conclude that doping can be understood with the assumption of a narcissistic civilization, focused on technology, that calls for the use of PEDs.

This paper analyses the role of external pressures, internal motivations and their interplay, with the intention of identifying whether they drive substantive or instead symbolic implementation of ISO 14001. The context is one of economic crisis. We focus on Greece, where the economic crisis has weakened the country’s institutional environment, and analyse qualitatively new interview data from 45 ISO 14001 certified firms. Our findings show that weak external pressures can lead to a symbolic implementation of ISO 14001, as firms can (...) defend their legitimacy without incurring the costs of internalization in the local market; weak external pressures can lead to substantive implementation of ISO 14001 when firms have strong internal motivations seeking to strategically differentiate from competitors in international markets. Firms internalize ISO 14001 so as to restore their legitimacy and reputation in foreign markets and stimulate their competitiveness; and strong internal motivations pave the way for companies to stimulate their competitiveness by enhancing their efficiency, as some companies might strengthen their position in the local market by implementing ISO 14001 substantively. The contribution of this paper to the literature on ISO 14001 internalization lies in refining existing theory on the importance of internal motivations for the substantive implementation of ISO 14001 in the context of economic crisis. In addition, this paper extends current theory by challenging studies that dismiss the importance of external pressures. We argue that the intensity of external pressures influences the internalization of ISO 14001, but propose that this relationship might not be linear. (shrink)

To be human is to be autonomous, yet this is a trait that most of us lack. We are subject to forces external to our being. We are workers; we are citizens; we are needful creatures. Humanity-proper in these times of neoliberal omnipotence is defined differently. The key terms are familiar: personal betterment, personal responsibility, productivity, pleasantness. A forked tongue slithers in our conscience, tells us that these are the traits of the human condition. Through Bataille, this paper argues the (...) substrate of these oft repeated familiar mantras are other. Neoliberal subjects, propelled by need, understand themselves along the axis of the useful choice. The paper turns to myth to understand the interdependence of need and choice, and how this interdependence posits being as always in desire but never in pleasure. Revisiting Don Giovanni, a character central to Acéphalic thought, and the commentary of Søren Kierkegaard, we think in terms of non-abstraction, of pleasurably floating in change, rather than toiling in desire. For it is by grace in the form of chance, that at the very time of transgression, that we – in and for an instant – become human, become as the sacred in the flesh. (shrink)

We study the topological models of a logic of knowledge for topological reasoning, introduced by Larry Moss and Rohit Parikh (1992). Among our results is the confirmation of a conjecture by Moss and Parikh, as well as the finite satisfiability property and decidability for the theory of topological models.

It is difficult to overestimate Paul Meehl's influence on judgment and decision-making research. His 'disturbing little book' Clinical versus Statistical Prediction: A Theoretical Analysis and a Review of the Evidence is known as an attack on human judgment and a call for replacing clinicians with actuarial methods. More than 40 years later, fast and frugal heuristics - proposed as models of human judgment - were formalized, tested, and found to be surprisingly accurate, often more so than the actuarial models that (...) Meehl advocated. We ask three questions: Do the findings of the two programs contradict each other? More generally, how are the programs conceptually connected? Is there anything they can learn from each other? After demonstrating that there need not be a contradiction, we show that both programs converge in their concern to develop domain-specific models of judgment and nonlinear process models that arise from the bounded nature of judgment. We then elaborate the differences between the programs and discuss how these differences can be viewed as mutually instructive: First, we show that the fast and frugal heuristic models can help bridge the clinical - actuarial divide, that is, they can be developed into actuarial methods that are both accurate and easy to implement by the unaided clinical judge. We then argue that Meehl's insistence on improving judgment makes clear the importance of examining the degree to which heuristics are used in the clinical domain and how acceptable they would be as actuarial tools.

The purpose of this paper is to introduce a form of update based on the minimization of the geodesic distance on a graph. We provide a characterization of this class using set- theoretic operators and show that such operators bijectively correspond to geodesic metrics. As distance is generated by distinguishability, our framework is appropriate in contexts where distance is generated by threshold, and therefore, when measurement is erroneous.

In this thesis we present two logical systems, $\bf MP$ and $\MP$, for the purpose of reasoning about knowledge and effort. These logical systems will be interpreted in a spatial context and therefore, the abstract concepts of knowledge and effort will be defined by concrete mathematical concepts.

Research on bounded rationality has two cultures, which I call ‘idealistic’ and ‘pragmatic’. Technically, the cultures differ on whether they build models based on normative axioms or empirical facts, assume that people's goal is to optimize or to satisfice, do not or do model psychological processes, let parameters vary freely or fix them, aim at explanation or prediction and test models from one or both cultures. Each culture tells a story about people's rationality. The story of the idealistic culture is (...) frustrating, with people in principle being able to know what they should do, but in practice systematically failing to do it. This story makes one hide in books for intellectual solace or surrender to the designs of someone smarter. The story of the pragmatic culture is empowering: If people are educated to use the right tool in the right situation, they do well. (shrink)

We give a characterization of extendibility in terms of embeddings between the structures H λ . By that means, we show that the GCH can be forced (by a class forcing) while preserving extendible cardinals. As a corollary, we argue that such cardinals cannot in general be made indestructible by (set) forcing, under a wide variety of forcing notions.

The resurrection axioms are forms of forcing axioms that were introduced recently by Hamkins and Johnstone, who developed on earlier ideas of Chalons and Veličković. In this note, we introduce a stronger form of resurrection and show that it gives rise to families of axioms which are consistent relative to extendible cardinals, and which imply the strongest known instances of forcing axioms, such as Martin’s Maximum++. In addition, we study the unbounded resurrection postulates in terms of consistency lower bounds, obtaining, (...) for example, failures of the weak square principle. (shrink)

This article examines the diversity of tactical interventions that transpired at the Whitney Museum of American Art in 2019, culminating in the resignation of the vice-chairman of its Board of Trustees. Instead of accepting the myth of museum neutrality, the activist campaign, spearheaded by the action-oriented movement Decolonize This Place, treated the Whitney as a site of ideological struggle, permeated by inner divisions and conflicting interests. Through their organizing efforts, activists prefigured a movement-based form of cultural production, mapped connections between (...) seemingly disparate struggles, and built decolonial solidarities. While the activists’ actions were essential to stage the antagonisms that had been dormant in the institution, a multiplicity of actors needed to step in during the process, creating multiple pressure points and taking sides in the division. To amplify the Whitney staffers’ attempt to hold the museum leadership accountable, they sought to bring political protest into the institution, challenging the very principle of counting who belongs to the community and who is excluded.

Psychology’s emphasis on individual experience has created idealised prototypes for gender identity, promulgated through traditional tools of psychological evaluation. Transgender and gender nonconforming people have been urged to fit into binary conceptions of such evaluations, at least until the recent depathologisation approved by the World Health Organization. The present theoretical study examines how psychological discourses around gender diversity and corporeality have been transformed. To this effect, it appeals to four arguments: to the activist mobilisation against homogeneous definitions of transness, to (...) the applicability of taxonomic systems’ categories, to the resistances against psychometric tests’ validity scales, and lastly, to issues concerning cross-cultural adaptation of terms, measurements and conceptions of bodily and gender identity.

Graphs are employed to define a variety of distance-based binary merging operators. We provide logical characterization results for each class of merging operators introduced and discuss the extension of this approach to the merging of sequences and multisets.

We pursue an account of merging through the use of geodesic semantics, the semantics based on the length of the shortest path on a graph. This approach has been fruitful in other areas of belief change such as revision and update. To this end, we introduce three binary merging operators of propositions defined on the graph of their valuations and we characterize them with a finite set of postulates.

Journal of Mathematical Logic, Volume 24, Issue 03, December 2024. When k is a finite field, [J. Becker, J. Denef and L. Lipshitz, Further remarks on the elementary theory of formal power series rings, in Model Theory of Algebra and Arithmetic, Proceedings Karpacz, Poland, Lecture Notes in Mathematics, Vol. 834 (Springer, Berlin, 1979)] observed that the total residue map [math], which picks out the constant term of the Laurent series, is definable in the language of rings with a parameter for (...) t. Driven by this observation, we study the theory [math] of valued fields equipped with a linear form [math] which restricts to the residue map on the valuation ring. We prove that [math] does not admit a model companion. In addition, we show that [math] is undecidable whenever k is an infinite field. As a consequence, we get that [math] is undecidable, where [math] maps f to its complex residue at 0. (shrink)

Alois Riegl’s essay “Die Stimmung als Inhalt der modernen Kunst” has been one of art historiography’s early attempts to bridge art and science. In this text, Riegl not only presents the background of some of his theoretical and methodological premises but he also provides an overarching argument for the way natural sciences af- fect modern spectatorship. In this way, he establishes the basis of a Kunstwollen for the ‘age of the natural sciences’ and describes its appropriate artistic traits. Addressing the (...) intellectual and historical context of the Stimmung Essay, this article shows how Riegl’s ideas work in a subtle and intricate manner, involving the combination of sensual and phenomenological observations to modes of knowl- edge. In this respect, the relation of art and science does not seem to be settled on a fixed contemplative basis but on the combination of the art with cognition and affects. (shrink)

Although the Chronicle of Theodore of Kyzikos has been known to scholarship and was included in Kurmbacher's Geschichte Der Byzantinischen Litteratur, it was later identified with the Synopsis Chronike, and hence excluded from any further research. The article reconsiders the text and its place in Byzantine historiography, focusing on its relationship to the Synopsis Chronike. It analyses their similarities and differences, particularly in terms of textual criticism, and examines possible connections between them. Finally, it concludes that the accepted hypothesis that (...) the two texts are one and the same (or mere variations of the same text) is not valid. Instead, it proposes that the Chronicle of Theodore of Kyzikos and the Synopsis Chronike are two distinct chronicles that derive from an earlier common archetype, which is now lost. (shrink)

Digitization of every daily procedure requires trustworthy verification schemes. People tend to overlook the security of the passwords they use, i.e. they use the same password on different occasions, they neglect to change them periodically or they often forget them. This raises a major security issue, especially for elderly people who are not familiar with modern technology and its risks and challenges. To overcome these drawbacks, biometric factors were utilized, and nowadays, they have been widely adopted due to their convenience (...) of use and ease of hardware installation. Many biometric-based authentication schemes were proposed, but despite the advantages that they offer, recent research has shown that biometrics by itself cannot be considered as an inviolable technique. Recently, we have proposed StegoPass, a novel method that obtains the 68 facial points of a user and utilizes them as a stego message to an image. This produced stego image was the password. Although the experiments conducted showed maximum security, it would be challenging to enhance the robustness of the proposed model for even more attacks. This paper examines the utilization of multimodal biometrics as the secret message embedded in the image. More specifically, besides the extraction of the facial points, we extract the unique minutiae moments and combine them in a feature vector. This feature vector is then embedded in the image. Two different datasets were used, and the security of the method was tested against state-of-the-art deep learning models, i.e. generative adversarial networks, to test whether the image could be digitally synthesized and fool the proposed verification scheme. The results proved that the new enhanced version of StegoPass offers an extremely secure method as its predecessor. (shrink)

This article explores the intertextual connection between Eteocles’ dream in Statius’ThebaidBook 2 and the brief reference to his ambiguous dream at Aesch.Sept.710−11. In Aeschylus’ play, Eteocles understands the true meaning of the dream belatedly, as he is about to enter into a duel with his brother Polynices. The article argues that the ambiguous character of the Aeschylean dream forms the basis of the dream in Statius, and that the poet develops the scene further through elements of epic dream sequences that (...) align his narrative with the epic tradition. However, Statius emphasizes even more the ambiguity of Eteocles’ dream to highlight the tragic nature of his character. Following ancient dream theorists, the discussion shows next that the obscurity of the dream in theThebaidcan be understood as the product of the fusion of different dream classes, which are evoked in the description of the dream in Statius. The proposed interpretation suggests that, on the basis of their personal experience of dreams and their familiarity with popular dream theories, Statius’ readers would have been able to perceive the irony between Laius’ message and Jupiter's true intentions, all of which enhance Eteocles’ tragic character.

La despatologización de las identidades trans en la última versión del CIE no concuerda todavía con una visión inclusiva en la práctica clínica. El enfoque trans-afirmativo intenta establecer nuevas prácticas de acompañamiento, alejándose de tradiciones biomédicas paternalistas. Pero en los últimos años, enfoques críticos de los estudios CTS y los estudios de género vienen a contrarrestar la necesidad de catalogación de las experiencias trans corporales y afectivas bajo etiquetas como disforia o incongruencia. Según dichos enfoques, no del todo hegemónicos, la (...) patologización es un síntoma sociocultural, e individualizarla conlleva el peligro de culpabilizar a los sujetos ante problemas de reconocimiento y tolerancia que tienen las sociedades mismas. Partiendo de estas premisas, se analizarán de forma situada e interdisciplinar los procesos por llevar a cabo para que el giro paradigmático hacia la despatologización sea integral y sustancial. La hipótesis por confirmar es que no puede haber cambio estructural en cuanto a la despatologización trans, sin diálogos interculturales, y sin examinar las distintas velocidades con las que avanzan las sociedades occidentales a nivel de inclusión. Ante esta tensión, la psicología tiene mucho que aprender de la participación ciudadana en salud. (shrink)

Centré sur l’univers polytechnicien de la première moitié du xixe siècle, le présent article souhaite mettre en regard les échanges scientifiques – oraux, épistolaires, ou liés à la diffusion de textes – développés au sein d’un « monde social » particulier avec les caractéristiques spécifiques de ce monde. En faisant dialoguer des considérations générales sur les différentes composantes de l’univers polytechnicien et une série de « vignettes » qui donnent à ces considérations de la chair historique, nous concluons à l’existence (...) d’un monde social dont les règles de fonctionnement – sociales, intellectuelles et morales –, l’équipement matériel, ainsi que les traits anthropologiques de ceux qui l’habitent font de lui un univers particulièrement propice au développement des échanges entre ses membres.
