В работе ставится вопрос о роли изобразительного начала в абстрактном искусстве Франции периода после Второй мировой войны. Рассматривая творчество и теоретические суждения ведущих мастеров пейзажной абстракции, ташизма, оп-арта, автор приходит к заключению, что принцип мимесиса был не исключен из их искусства, но переосмыслен: задача правдоподобного воссоздания зримых форм сменилась поиском способов обобщенной передачи процессов и структур внешнего мира. Творчество таких мастеров, как Альберто Джакометти и Никола де Сталь, «вырастивших» фигуративные формы из нефигуративных, показывает, что между двумя системами нет непроходимой границы, (...) но существует множество переходных стадий. Заключительная глава посвящена направлению повествовательной фигуративности и роли абстрагирующих моделей реальности в нем. (shrink)

Ontologies represent the standard way to model the knowledge about specific domains. This holds also for the legal domain where several ontologies have been put forward to model specific kinds of legal knowledge. Both for standard users and for law scholars, it is often difficult to have an overall view on the existing alternatives, their main features and their interlinking with the other ontologies. To answer this need, in this paper, we address an analysis of the state-of-the-art in legal ontologies (...) and we characterise them along with some distinctive features. This paper aims to guide generic users and law experts in selecting the legal ontology that better fits their needs and in understanding its specificity so that proper extensions to the selected model could be investigated.

Several theories propose that one of the core functions of inner speech (IS) is to support subjects in the completion of cognitively effortful tasks, especially those involving executive functions (EF). In this paper we focus on two populations who notoriously encounter difficulties in performing EF tasks, namely, people diagnosed with schizophrenia who experience auditory verbal hallucinations (Sz-AVH) and people within the Autism Spectrum Conditions (ASC). We focus on these two populations because they represent two different ways in which IS can (...) fail to help in EF tasks, which can be illustrative for other mental conditions. First, we review the main components of EF (Section 1). Then we explain the functions that IS is taken to perform in the domain of EF (Section 2) and review the evidence concerning problems about EF in the two populations of our study: Sz-AVH (Section 3) and ASC (Section 4). After this we further detail our account about what a properly functioning IS can do for both populations and how different IS profiles may impact EF performance: in the case of Sz-AVH, the uncontrolled and intrusive character of IS negatively affects EF performance, whereas in ASC, EF is not sufficiently supported by IS, given the tendency in this population to present a diminished use of IS (Section 5). We finally briefly discuss Attention Deficit/Hyperactivity Disorder (ADHD) and Developmental Language Disorders (DLD). (shrink)

A substantial body of experimental evidence has demonstrated that labels have an impact on infant categorization processes. Yet little is known regarding the nature of the mechanisms by which this effect is achieved. We distinguish between two competing accounts: supervised name‐based categorization and unsupervised feature‐based categorization. We describe a neurocomputational model of infant visual categorization, based on self‐organizing maps, that implements the unsupervised feature‐based approach. The model successfully reproduces experiments demonstrating the impact of labeling on infant visual categorization reported in (...) Plunkett, Hu, and Cohen (2008). It mimics infant behavior in both the familiarization and testing phases of the procedure, using a training regime that involves only single presentations of each stimulus and using just 24 participant networks per experiment. The model predicts that the observed behavior in infants is due to a transient form of learning that might lead to the emergence of hierarchically organized categorical structure and that the impact of labels on categorization is influenced by the perceived similarity and the sequence in which the objects are presented. The results suggest that early in development, say before 12 months old, labels need not act as invitations to form categories nor highlight the commonalities between objects, but they may play a more mundane but nevertheless powerful role as additional features that are processed in the same fashion as other features that characterize objects and object categories.

En el presente texto proponemos realizar un primer trazado de una zona de correspondencia entre cuerpo y materialidad, para replantear esta materialidad a partir de ciertas categorías conceptuales. La hipótesis planteada es que hay determinadas concepciones del cuerpo en el pensamiento del siglo XX en adelante que suponen una materialidad no reductible a principios de determinación, una materialidad emparentada con la libertad, donde la necesidad se subsume a la contingencia concreta de los cuerpos. Nos proponemos bosquejar una construcción conceptual de (...) materialidad que pueda articular diferentes pensamientos que incluyen al cuerpo de un modo relevante, especialmente el de Jean-Luc Nancy.

According to several researchers, core affect lies at the foundation of our affective lives and may be characterized as a consciously accessible state combining arousal (activated-deactivated) and valence (pleasure-displeasure). The interaction between these two dimensions is still a matter of debate. In this paper we provide a novel hypothesis concerning their interaction, by arguing that subjective arousal levels modulate the experience of a stimulus’ affective quality. All things being equal, the higher the arousal, the more a given stimulus would be (...) experienced as pleasant (or unpleasant). While marshaling some preliminary evidence in favor of this hypothesis, we also show how it might be relevant in reframing our conception of depressive disorders (i.e., major and bipolar depression).

Regulatory schema has shifted from government to governance-based systems. One particular form that has emerged at the international level is the multi-stakeholder voluntary code of conduct (MSVC). We argue that such codes are not only simply mechanisms by which various stakeholders attempt to govern the action of the corporation but also systems by which each stakeholder attempts to gain or retain some legitimacy goal. Each stakeholder is motivated by strategic legitimacy goal to join the code, and once a member, is (...) also required to assist in maintaining the institutional legitimacy of the code, resulting in “networked legitimacy.” We begin our analysis of these systems by first exploring the growth and structure of such MSVCs, and then building an analytical framework using strategic and institutional legitimacy as they apply to such MSVCs. We contribute to the codes of conduct literature by developing the construct of networked legitimacy from strategic and institutional legitimacy. We then apply our framework to the United Nations Global Compact, one of the predominant MSVCs today. In doing so, we: (1) demonstrate how different stakeholders are pursuing different types of legitimacy through their participation in the code, (2) examine the specific opportunities and risks in terms of what we have called “networked legitimacy” posed by the institutional design of actual MSVCs, and (3) create an argument for three pillars supporting the legitimacy of MSVCs.

We consider embeddings of structures which preserve spectra: if g: M → S with S computable, then M should have the same Turing degree spectrum (as a structure) that g(M) has (as a relation on S). We show that the computable dense linear order L is universal for all countable linear orders under this notion of embedding, and we establish a similar result for the computable random graph G. Such structures are said to be spectrally universal. We use our results (...) to answer a question of Goncharov, and also to characterize the possible spectra of structures as precisely the spectra of unary relations on G. Finally, we consider the extent to which all spectra of unary relations on the structure L may be realized by such embeddings, offering partial results and building the first known example of a structure whose spectrum contains precisely those degrees c with c′ ≥T 0″.

This is a comprehensive analysis of the idea of libertas and its conflicting uses in the political struggles of the late Roman Republic. By reconstructing Roman political thinking about liberty against the background of Classical and Hellenistic thought, it excavates two distinct intellectual traditions on the means allowing for the preservation and the loss of libertas. Considering the interplay of these traditions in the political debates of the first century BC, Dr Arena offers a significant reinterpretation of the political struggles (...) of the time as well as a radical reappraisal of the role played by the idea of liberty in the practice of politics. She argues that, as a result of its uses in rhetorical debates, libertas underwent a form of conceptual change at the end of the Republic and came to legitimise a new course of politics, which led progressively to the transformation of the whole political system.

With every new recursive relation R on a recursive model , we consider the images of R under all isomorphisms from to other recursive models. We call the set of Turing degrees of these images the degree spectrum of R on , and say that R is intrinsically r.e. if all the images are r.e. C. Ash and A. Nerode introduce an extra decidability condition on , expressed in terms of R. Assuming this decidability condition, they prove that R is (...) intrinsically r.e. if and only if a natural recursive-syntactic condition is satisfied. We show that, while a recursive non-intrinsically r.e. relation may have a two element degree spectrum, a non-intrinsically r.e. relation which satisfies the Ash–Nerode decidability condition has an infinite degree spectrum. We also study several related decidability conditions and their effects on the degree spectra, including some conditions which are sufficient to obtain every r.e. degree in a spectrum. (shrink)

Computable model theory, also called effective or recursive model theory, studies algorithmic properties of mathematical structures, their relations, and isomorphisms. These properties can be described syntactically or semantically. One of the major tasks of computable model theory is to obtain, whenever possible, computability-theoretic versions of various classical model-theoretic notions and results. For example, in the 1950's, Fröhlich and Shepherdson realized that the concept of a computable function can make van der Waerden's intuitive notion of an explicit field precise. This led (...) to the notion of a computable structure. In 1960, Rabin proved that every computable field has a computable algebraic closure. However, not every classical result “effectivizes”. Unlike Vaught's theorem that no complete theory has exactly two nonisomorphic countable models, Millar's and Kudaibergenov's result establishes that there is a complete decidable theory that has exactly two nonisomorphic countable models with computable elementary diagrams. In the 1970's, Metakides and Nerode [58], [59] and Remmel [71], [72], [73] used more advanced methods of computability theory to investigate algorithmic properties of fields, vector spaces, and other mathematical structures.

In spatial sequence synaesthesia ordinal stimuli are perceived as arranged in peripersonal space. Using fMRI, we examined the neural bases of SSS and colour synaesthesia for spoken words in a late-blind synaesthete, JF. He reported days of the week and months of the year as both coloured and spatially ordered in peripersonal space; parts of the days and festivities of the year were spatially ordered but uncoloured. Words that denote time-units and triggered no concurrents were used in a control condition. (...) Both conditions inducing SSS activated the occipito-parietal, infero-frontal and insular cortex. The colour area hOC4v was engaged when the synaesthetic experience included colour. These results confirm the continued recruitment of visual colour cortex in this late-blind synaesthetes. Synaesthesia also involved activation in inferior frontal cortex, which may be related to spatial memory and detection, and in the insula, which might contribute to audiovisual integration related to the processing of inducers and concurrents.

In his Democratic justice and the social contract, Weale presents a distinctive contingent practice-dependent model of ‘democratic justice’ that relies heavily on a condition of just social and political relations among equals. Several issues arise from this account. Under which conditions might such just social and political relations be realised? What ideal of equality is required for ‘democratic justice’? What are its implications for the political ideal of citizenship? This paper focuses on these questions as a way to critically reconsider (...) Weale’s model. After presenting Weale’s procedural constructivism, I distinguish his model from an institutional practicedependent model, one salient example of which is Rawls’s political constructivism. This distinction allows for a formulation of the social and political equality required for justice in each case. The contingent model assumes that an equality of ‘status’ will generate just social practices, yet it fails to recognise that an equality of ‘role’ is also important to ensure citizens’ compliance. The paper ultimately seeks to show that the contingent model is insufficient to ensure that just social practices will become stable. (shrink)

We examine whether a taxpayer’s decision to choose a taxpayer-favorable characterization of income is associated with contextual and individual dimensions of that decision. Using a 2 × 2 factorial experimental design, we manipulate the prevailing social norm on whether there is a general belief that a specific form of income should be characterized as a capital gain or as ordinary income, and the group affiliation on whether the individual is making a tax characterization decision as a sole proprietor or as (...) a member of a group practice. Moreover, we measure participants’ fairness perception of characterizing the income as capital gains versus ordinary. We study the decisions of 180 graduate business and accounting students from two US business schools to explore these dimensions using a tax-ambiguous income situation. Results indicate that both contextual and individual dimensions impact taxpayer decisions. Specifically, the social norm and fairness perception of characterizing income as capital gains affects the likelihood of choosing such a characterization. Being a sole proprietor or a member of a group practice does not have any significant main effect. However, relative to all other conditions, taxpayers are most likely to characterize income as capital gains when both the social norms are for capital gains characterization and when the taxpayer is a member of a group practice. Results remain largely robust to a variety of alternative explanations. We conclude the paper with a discussion of our findings and their implications for tax policy, enforcement, and research.

The outbreak of SARS-CoV-2 has exposed a shared condition of vulnerability on a global scale. How can we use vulnerability as an effective paradigm in order to foster collective political initiatives? This essay claims that the idea of care is key to understand the vulnerability framework as being both an epistemic and a political resource to address ethical issues. The first half of the essay recollects several arguments in Adriana Cavarero’s and Judith Butler’s most recent works, insofar as both theorists (...) have insisted on the notion of vulnerability in order to interpret contemporary political mobilizations. The second part of the essay retraces a constellation of practices of care in the works of several Black and decolonial feminist thinkers situated in different socio-political contexts. Whereas for Christina Sharpe and Saidiya Hartman the focus is on the matter of Blackness and Black lives in their constitutive vulnerability, both Cristina Rivera Garza’s and Sayak Valencia’s works remarkably insist on the specific socio-political context of today’s Mexico. These authors urge the readers to adopt a critical posture when encountering official narratives, also because in their texts they exhibit their own vulnerability. For them, writing, their writing is an ethical demand to imagine alternatives and to foster new entanglements between bodies persisting on the margins, at the limits of the norms that regulate legibility.

In this paper we (Laura Giordano, Nicola Olivetti and myself) propose a conditional logic to represent iterated belief revision systems. We propose a set of postulates for belief revision which are a small variant of Darwiche and Pearl's ones.The resulting conditional logic has a standard semantics in terms of selection function models, and provides a natural representation of epistemic states. A Representation Theorem establishes a correspondence between iterated belief revision systems and conditional models. Our Representation Theorem does not entail Gärdenfors' (...) Triviality Result.

The purpose of this article is to identify how modern Russia can build good relationships between multiple Russian religions and the state. At present there are many obstacles standing in the way of achieving this goal. The article includes a great many statistics, and discusses political, social, and religious views of the issue.The working Russian Constitution provides major legal provisions for democratic relationships between religions and the state. The law “On Freedom of Conscience and Religious Associations” (1997) clarified constitutional provisions. (...) It should not forgotten that Russia is a secular state claiming to respect all religions. No doubt the supremacy of Orthodoxy in Russia after 1721 and the extreme atheism that arose in the Soviet Union after 1917 influenced people’s minds greatly. While the countries in Western Europe were moving from religiosity to secularism, Russia was developing the other way around. But while respecting all religions, Russia should not forget to be mindful of extremism. Religious associations themselves are likewise uneasy about the danger presented by certain mystic, neo-pagan, and destructive sects. The author argues that the best compromise between religions and the modern Russian state canonly be achieved on the basis of equality and freedom. (shrink)

“ Tripping through ” is an invitation to plunge into the invisible relationships of hard and soft computer matter through sensuous mediation. The projects outlined are designed to provoke and capture the specific behavior of individual computer components through the use of appropriate software fragments. If one approaches a digital apparatus with a transducer that transforms electromagnetic fields into acoustic waves, the analytical sphere is changed into concrete acoustical phenomena and enters the world of sensation (electromagnetic emissions can be picked (...) using induction microphones and output as acoustic signals. A suitable example is a Monacor telephone adapter AC-71/3,5MM). In choreographies for software and computer parts, these become actors in noise pieces for and in computers. Machine noises can be mediated for the public. They reveal the activity of computer programs in the widest sense and the activity of the computers or computer parts they are running on. The time and space of computer processes and memory span different levels of reality during “ runtime. ” Software being processed within this system of coordinates creates its own temporal and spatial dimensions, which are staged for an audience to provide a sensual experience: that of logic encountering the physical world.

Bortolotti argues that we cannot distinguish delusions from other irrational beliefs in virtue of their epistemic features alone. Although her arguments are convincing, her analysis leaves an important question unanswered: What makes delusions pathological? In this paper I set out to answer this question by arguing that the pathological character of delusions arises from an executive dysfunction in a subject’s ability to detect relevance in the environment. I further suggest that this dysfunction derives from an underlying emotional imbalance—one that leads (...) delusional subjects to regard some contextual elements as deeply puzzling or highly significant.

Der Beitrag greift das komplexe Kuhnsche Konzept des „Exemplars“ anhand einiger Schlüsselpassagen aus dem Postscript-1969 und The Essential Tension auf. Der Begriff „Exemplar“ bezieht sich auf die tiefere philosophische Bedeutung des wissenschaftlichen Paradigmas: Der „normale“ Wissenschaftler kann unter Bezugnahme auf das Paradigma seine oder ihre Forschung durchführen, indem er Ähnlichkeitsurteile zwischen verschiedenen Problemen fällt. Solche Urteile beruhen auf einer Wahrnehmungsfähigkeit, die jeder expliziten Regel vorausgeht und die sowohl als erlernt als auch als primitiv definiert wird. In diesem Beitrag soll dieser (...) doppelte Aspekt der Ähnlichkeitswahrnehmung aus der Sicht der verkörperten Simulationstheorie analysiert werden. Das Kuhnsche Konzept des Exemplars kann durch die Berücksichtigung des Wertes der Verkörperung geklärt und vertieft werden. Die Mechanismen einer „gebildeten“ Wahrnehmung können in den automatischen Mechanismen der Wahrnehmungsspiegelung identifiziert werden, auf denen die verkörperte Kognition beruht. (shrink)
