When the language-dominant hemisphere is damaged by a focal lesion, the brain may reorganize the language network through functional and structural changes known as adaptive plasticity. Adaptive plasticity is documented for triggers including ischemic, tumoral, and epileptic focal lesions, with effects in clinical practice. Many questions remain regarding language plasticity. Different lesions may induce different patterns of reorganization depending on pathologic features, location in the brain, and timing of onset. Neuroimaging provides insights into language plasticity due to its non-invasiveness, ability (...) to image the whole brain, and large-scale implementation. This review provides an overview of language plasticity on MRI with insights for patient care. First, we describe the structural and functional language network as depicted by neuroimaging. Second, we explore language reorganization triggered by stroke, brain tumors, and epileptic lesions and analyze applications in clinical diagnosis and treatment planning. By comparing different focal lesions, we investigate determinants of language plasticity including lesion location and timing of onset, longitudinal evolution of reorganization, and the relationship between structural and functional changes.

L’articolo intende proporre una lettura del _Breve trattato sulle cause che possono far abbondare li regni d’oro e d’argento_ di Antonio Serra incentrata su una storia delle arti di governo. Ricostruendo il dibattito napoletano sulle cause della crisi monetaria degli inizi del XVII secolo e focalizzando l’attenzione sul problema delle pratiche di governo della moneta, l’obiettivo del saggio è quello di sottrarre il trattato di Serra all’ipoteca di una retrospettiva sulla scienza economica per inquadrarlo all’interno dei problemi politici del (...) proprio tempo.

In actuarial parlance, the price of an insurance policy is considered fair if customers bearing the same risk are charged the same price. The estimate of this fair amount hinges on the expected value obtained by weighting the different claims by their probability. We argue that, historically, this concept of actuarial fairness originates in an Aristotelian principle of justice in exchange (equality in risk). We will examine how this principle was formalized in the 16th century and shaped in life insurance (...) during the following two hundred years, in two different interpretations. The Domatian account of actuarial fairness relied on subjective uncertainty: An agreement on risk was fair if both parties were equally ignorant about the chances of an uncertain event. The objectivist version grounded any agreement on an objective risk estimate drawn from a mortality table. We will show how the objectivist approach collapsed in the market for life annuities during the 18th century, leaving open the question of why we still speak of actuarial fairness as if it were an objective expected value.

Nel corso della sua lunga attività di insegnamento presso le Università di Padova e di Bologna, Pietro Pomponazzi si confrontò ripetutamente con il De anima di Aristotele e con il relativo commento di Averroè. Il suo primo corso svolto in qualità di professore ordinario a Padova risale al 1499, il frutto più maturo delle sue riflessioni è sicuramente il celebre Tractatus de immortalitate animae, pubblicato a Bologna nel 1516, che lo proiettò al centro di polemiche, discussioni e condanne. Gli studenti (...) del Pomponazzi ci hanno tramandato gli appunti di numerosi suoi commenti al Corpus aristotelicum. Fra questi, di particolare interesse è l'esposizione sul primo libro del De anima, che il professore svolse a Padova sul cadere dell'anno 1503, e che fu riportata e messa in bella copia da un nobile veneziano, Antonio Surian, che frequentava le sue lezioni. Il volume presenta l'Expositio super I De anima secondo l'unico manoscritto che ci è pervenuto, conservato nella Biblioteca Nazionale di Napoli (VIII D 81), e reca un fondamentale contributo alla ricostruzione della formazione e dello sviluppo della dottrina psicologica pomponazziana.

This paper provides a detailed analysis of how, according to Kant, the moral badness of some third parties’ actions can be established with certainty (by anyone, not only by the agent’s own conscience or by God). This account helps clarify why Kant affirms that some forms of wrongdoing (of which there are a “multitude of woeful examples”) can be demonstrated to be immoral, while excluding the possibility of proving the moral goodness of any action. The paper concludes by arguing that (...) the possible certainty of judgements imputing immorality to actions of others is not rational but rather moral. (shrink)

Schizophrenia is characterised by marked language deficits, but it is not clear how these deficits arise from the alteration of genes related to the disease. The goal of this paper is to aid the bridging of the gap between genes and schizophrenia and, ultimately, give support to the view that the abnormal presentation of language in this condition is heavily rooted in the evolutionary processes that brought about modern language. To that end we will focus on how the schizophrenic brain (...) processes language and, particularly, on its distinctive oscillatory profile during language processing. Additionally, we will show that candidate genes for schizophrenia are overrepresented among the set of genes that are believed to be important for the evolution of the human faculty of language. These genes crucially include (and are related to) genes involved in brain rhythmicity. We will claim that this translational effort and the links we uncover may help develop an understanding of language evolution, along with the aetiology of schizophrenia, its clinical/linguistic profile, and its high prevalence among modern populations.

Exploramos aquí la conexión entre los conceptos de riesgo e igualdad en el argumento del observador imparcial. La concepción de la justicia que elegiría un observador imparcial se justifica por la pureza del procedimiento de elección. Sin embargo, si modelizamos esta decisión utilizando medidas del riesgo habituales en matemática financiera, veremos cómo el criterio de elección del observador bajo el velo de la ignorancia contiene una preferencia implícita por el grado de desigualdad resultante. Esto nos obliga a reconsiderar la pureza (...) procedimental de la elección. (shrink)

In the so-called digital culture, there is a constant presence of radical transformations on the cognitive and affective dimensions of the relations established among teachers and students. Upon this ubiquitous accessibility of information, the very historical and hierarchically verticalized relation between teachers and students has been increasingly questioned. Upon this situation, the authors in this article aim at stating that the revitalization of concepts developed by Paulo Freire, mainly the ones discussed in the books: ‘Pedagogy of Hope’, that sought a (...) re-encounter with ‘Pedagogy of the Oppressed’, ‘Extension or Communication’ and ‘Pedagogy of Freedom’ became essential to understanding how the relationship between teachers and students can be mutually re-signified. In these times of digital culture, we argue that the revitalization of the critical thinking proposed by Freire is able to foment a dialogical communication both in the pedagogical link shared by teachers and students and in the transformation of information into substantially and ethically experienced concepts. Such substantial and ethical experiences are the ones able to attest that the pedagogy of hope and the pedagogy of freedom are possible, provided they are constituted with the students and not for them.

We defend, from a contractarian perspective, that the fair price of an insurance policy is the amount that the contracting parties agree when they are both equally uncertain about the insured event. Drawing on the approach developed by R. Sugden in _The Community of Advantage_, we answer two standard objections raised against contractarianism in the actuarial sciences: (1) people are not wise enough to assess their actuarial risks; (2) they are not rational enough to decide which insurance policy suits them (...) better. We show under which circumstances people can make fair actuarial agreements, without presupposing any objective risk or rationality benchmarks. (shrink)

Background Neuroimaging and lesion studies suggested that the dorsolateral prefrontal and posterior parietal cortices mediate visual metacognitive awareness. The causal evidence provided by non-invasive brain stimulation, however, is inconsistent. -/- Objective/hypothesis Here we revisit a major figure discrimination experiment adding a new Kanizsa figure task trying to resolve whether bilateral continuous theta-burst transcranial magnetic stimulation (cTBS) over these regions affects perceptual metacognition. Specifically, we tested whether subjective visibility ratings and/or metacognitive efficiency are lower when cTBS is applied to these two (...) regions in comparison to an active control region. -/- Methods A within-subjects design including three sessions spaced by one-week intervals was implemented. In each session, every participant was administered bilateral cTBS to either prefrontal, control or parietal cortices. Two concurrent tasks were performed, a real and an illusory figure task, stabilising objective performance with use of an adaptive staircase procedure. -/- Results When performing the replicated task, cTBS was found insufficient to disrupt neither visibility ratings nor metacognitive efficiency. However, with use of Kanizsa style illusory figures, cTBS over the dorsolateral prefrontal, but not over the posterior parietal cortex, was observed to significantly diminish metacognitive efficiency. -/- Conclusion(s) Real and illusory figure tasks demonstrated different cTBS effects. A possible explanation is the involvement of the prefrontal cortex in the creation of expectations, which is necessary for efficient metacognition. Failure to replicate previous findings for the real figure task, however, cannot be said to support, conclusively, the notion that these brain regions have a causal role in metacognitive awareness. This inconsistent finding may result from certain limitations of our study, thereby suggesting the need for yet further investigation. (shrink)

Both Quine and Davidson put forth programs of empirical semantics satisfying the conditions that characterize the so-called “standpoint of interpretation.” Quine’s less ambitious program of radical translation rests upon two buttresses: causality and empathy. Davidson’s more ambitious program of radical interpretation replaces causality with truth and empathy with rationality. Although the replacement of causality with intersubjective truth seems to me to be a fully justified move, I nevertheless contend that it is more realistic to develop the work of interpretation drawing (...) upon Quine’s less ambitious requirement of empathy than upon Davidson’s view of human agency as rational agency. In order to substantiate this contention, I present an argument to the effect that Davidson’s characterization of human agency as rational is not compatible with his other requirement that truth should pro-vide the essential link connecting speech with environment and action.

In this paper I suggest a reconstruction of the traditional concepts of con-tinent and incontinent action. This reconstruction proceeds along the lines of a standpoint of bounded rationality. My suggestion agrees with some relevant aspects of Davidson’s treatment of this topic. One of these aspects is that incontinent action is typically signalled by the following two subjective experiences: a feeling of surprise towards one’s own action and a difficulty in understanding oneself; another is that incontinence cannot simply be disposed of (...) in terms of some inability of the agent to avoid “succumbing to temptation”; still another is the view that inconti-nent action is common in real human affairs. But my suggestion dis-agrees with other relevant aspects of Davidson’s treatment of inconti-nence too. In particular, it avoids what I take to be its two major draw-backs. These are a view of continent action that falls prey to a com-pletely unrealistic concept of psychological rationality and the idea that incontinence necessarily involves a dimension of essential irrationality.

The debate concerning human rationality has been revolving around four main standpoints: 1) Unbounded rationality, 2) Optimization under constraints, 3) Heuristics and biases, and 4) Ecological rationality. Typically, proponents of 3) and 4) criticize models 1) and 2) for their cognitive unrealism. However, many ethologists contend that it makes sense to account for data gathered in animal behaviour research along the lines defined by the latter models. Elaborating upon this contention, Stanovich suggested recently a fifth standpoint in this debate – (...) I’ll call it ‘Brute Rationality’. According to it, traditional rational choice models are more appropriate to account for the behaviour of creatures endowed with simple cognitive architectures rather than to account for human behaviour. In my talk, I´ll contend that the term ‘rationality’ is being used in this debate to cover too wide a semantic area. In fact, once one distinguishes the different meanings associated with it, the positions defining this debate reveal themselves to be much less clear than what is usually taken to be the case.

Classification learning is a preeminent human ability within the animal kingdom but the key mechanisms of brain networks regulating learning remain mostly elusive. Recent neuroimaging advancements have depicted human brain as a complex graph machinery where brain regions are nodes and coherent activities among them represent the functional connections. While long-term motor memories have been found to alter functional connectivity in the resting human brain, a graph topological investigation of the short-time effects of learning are still not widely investigated. For (...) instance, classification learning is known to orchestrate rapid modulation of diverse memory systems like short-term and visual working memories but how the brain functional connectome accommodates such modulations is unclear. We used publicly available repositories (openfmri.org) selecting three experiments, two focused on short-term classification learning along two consecutive runs where learning was promoted by trial-by-trial feedback errors, while a further experiment was used as supplementary control. We analyzed the functional connectivity extracted from BOLD fMRI signals, and estimated the graph information processing in the cerebral networks. The information processing capability, characterized by complex network statistics, significantly improved over runs, together with the subject classification accuracy. Instead, null-learning experiments, where feedbacks came with poor consistency, did not provoke any significant change in the functional connectivity over runs. We propose that learning induces fast modifications in the overall brain network dynamics, definitely ameliorating the short-term potential of the brain to process and integrate information, a dynamic consistently orchestrated by modulations of the functional connections among specific brain regions.

Resumo: Os processos avaliativos, na universidade, são perpassados por um ethos que prima pela quantificação e pelo ranqueamento. Em decorrência, observa-se cada vez mais a descaracterização da avaliação na sua acepção qualitativa e, consequentemente, formativa. A afirmação desse ethos, na universidade, bem como na sociedade, é facilitada pelos algoritmos de big data, os quais estão na base da constituição da chamada “sociedade métrica”, em que há uma tendência geral para utilizar formas quantitativas para realizar classificações sociais. Neste texto, com respaldo (...) em revisão de literatura, objetiva-se refletir sobre dois processos de avaliação de docentes que atuam no ensino superior e que ultrapassam o espaço acadêmico pela sua dimensão pública espetacularizada: a) o ranqueamento da produção docente, por meio do índice h; e b) a avaliação realizada por estudantes em sites públicos, neste caso específico, o site de avaliação docente ratemyprofessors.com. A partir destas duas estratégias de avaliação, professores, pesquisadores e alunos envolvem-se em uma espécie de certame onde se mostrar, ser visto, monitorado, classificado passa a ser critério de aprovação (percebido) ou, no limite, perda de financiamentos e do próprio trabalho (cancelado).

Between ranking and rating: Digital evaluation of professors in the metric society Abstract: Evaluation processes at universities are permeated by an ethos that emphasizes quantification and ranking. As a result, an increasing discharacterization of the qualitative and thus educational sense of evaluation is observed. The affirmation of this ethos in universities, and in society as a whole, is facilitated by big data algorithms, which are at the foundation of the constitution of the so-called ‘metric society’, in which there is a general trend to use quantitative forms to conduct social classifications. This text, supported by a review of the literature, reflects on two processes of evaluation of professors of higher education that go beyond the academic space because of their spectacularized public dimension: the ranking of professor production, by the “h index” and b) evaluations conducted by students on public online sites, in this case, the ratemyprofessors.com site. Based on these two evaluation strategies, professors, researchers, and students are involved in a dispute in which displaying oneself, being seen, monitored, and classified become criteria for (perceived) approval, or, at the limit, for a loss of financing for one’s work (canceling).

Em tempos de cultura digital, observa-se o acesso a uma quantidade incomensurável de informações sem que sejam feitas relações que poderiam transformá-las em conceitos. Uma vez que prevalece o uso instrumental de tais informações, arrefece concomitantemente a postura ética que o questiona. É nesse contexto que o professor ocupa um posto decisivo no que diz respeito à organização e à discussão de tais informações com seus alunos. Este artigo tem como objetivo argumentar que a postura de Pedro Goergen como educador (...) oferta aos alunos um tipo de relação que faz com que a própria figura do professor seja eticamente ressignificada nessa sociedade de cultura digital.

Esse texto é um escrito que, ao final, é um termo médio entre um Artigo e um Ensaio. O objetivo é expor nossa compreensão sobre o sentido d“o material” e as implicações onto(epistemo)lógicas desta concepção no pensamento de Karl Marx. Em plano geral, primeiramente, nosso texto discorre sobre o que nomeamos de “a questão primeira”, qual seja: o que é “o material” no interior e no contexto dos escritos de Marx? Para cumprir essa tarefa procedemos com leituras de textos marxianos (...) visando identificar, neles, passagens importantes aonde o conceito de “material” é pressuposto, citado ou implicado. No segundo momento do texto, afirmamos que os resultados das análises do sentido d“o material” nos possibilitam induzir e/ou deduzir que o materialismo de Marx é dialético. Por fim, apresentamos algumas conclusões que decorrem do aceite da validade e veracidade da tese de que Marx pensa dialeticamente, de que seu materialismo é dialético. (shrink)

Every now and then when watching a movie, we come across faces in which we recognize a significant value, because they represent some important cultural models we use to assign meaning to our experience of the world. By way of example, I will discuss the faces of the protagonists of two recent films, Abdellatif Kechiche’s La vie d’Adele. Chapitres 1 & 2 (2013; English title Blue Is the Warmest Colour) and Leonor Serraille’s Jeune femme (2017), comparing them with the faces (...) of the protagonists of some older movies, such as Andrew Adamson and Vicky Jenson’s Shrek (2001) and James Cameron’s Avatar (2009). I will argue that the way in which the faces are portrayed is similar to the narrative structure of the stories of the characters they belong to, and that the signs and narrative structures used to construct the discourses about the world in those films are at the same time similar to those of two important cultural models of what it means to be young men and women in our times. As these cultural models are different, yet interconnected, I will argue that the most meaningful faces in cinema change due to the transformation of the cultural models they derive from and that a sociosemiotic method based on a structuralist vision of culture can help identify the most culturally significant symbolic faces on screen, and elsewhere.

The article analyses the concept of actual infinity in William of Ockham’s thought, thanks to a close reading of his writings, first those on physics, where he argues more than once the existence of the actual infinity, intended as a set of infinite parts in act present in a continuum. By virtue of this representation of infinity, Ockham also states that two sets with infinite parts are not necessarily equal, but one of the two can be greater than the other, (...) as would happen with the revolutions of the moon and the sun in an endless time. Nonetheless, in the theological works, the Franciscan seems to have apparently a different position, since he denies the possibility of the actual infinity, either as a set of infinite entities existing all simultaneously, or as an infinite entity, since in both cases a limit would be placed on God’s omnipotence. Ockham instead demonstrates that he has a double vision of the actual infinity, similar to that of Cantor, as already proposed by Annaliese Maier. The essay will therefore show the compatibility of Ockham’s physics and theological writings by virtue of the different meanings of infinity. (shrink)

This paper introduces a formal concept of ideology and ideological system. The formalization takes ideologies and ideological systems to be situated in agent societies. An ideological system is defined as a system of operations able to create, maintain, and extinguish the ideologies adopted by the social groups of agent societies. The concepts of group ideology, ideological contradiction, ideological dominance, and dominant ideology of an agent society, are defined. An ideology-based concept of social group is introduced. Relations between the proposed formal (...) concept of ideology and the classical concepts of ideology elaborated in social sciences are examined. A computational notation is presented, to support the realization of ideological systems in computationally implemented agent societies. The adequacy of the approach for the formal modeling and analysis of ideological issues is illustrated through three case studies. (shrink)
