El artículo se estructura en torno de tres tópicos que se proponen como aportes a la agenda y los debates sobre extensión crítica. Por una parte, los movimientos populares, su papel en las nuevas realidades latinoamericanas, sus formas de construcción y su carácter de sujetos centrales para la extensión. En segundo lugar, se analizan las funciones sustantivas, a partir de lo que llamamos la densidad epistémica o los desafíos de conocimiento de los movimientos y se analiza la propuesta de diálogo (...) de saberes en relación con esa densidad epistémica. Por último, compartimos algunas reflexiones acerca del diálogo de saberes desde la perspectiva metodológica, retomando los aportes del Educación Popular. (shrink)

Neuroimaging and psychophysiological techniques have proved to be useful in comprehending the extent to which the visual modality is pervasive in mental imagery, and in comprehending the specificity of images generated through other sensory modalities. Although further research is needed to understand the nature of mental images, data attained by means of these techniques suggest that mental imagery requires at least two distinct processing components.

We present the idea of searching for X-rays as a signature of the mechanism inducing the spontaneous collapse of the wave function. Such a signal is predicted by the continuous spontaneous localization theories, which are solving the “measurement problem” by modifying the Schrödinger equation. We will show some encouraging preliminary results and discuss future plans and strategy.

We present an experimental test of the validity of the Pauli Exclusion Principle for electrons based on the concept put forward a few years ago by Ramberg and Snow. In this experiment we perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a simple structure, it poses deep conceptual and interpretational problems. Here we describe the experimental method and recent experimental results, which (...) we interpret as an upper limit for the probability to violate the Pauli Exclusion Principle. We present also future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

In this paper we describe an experimental test of the validity of the Pauli Exclusion Principle (for electrons) which is based on a straightforward idea put forward a few years ago by Ramberg and Snow (Phys. Lett. B 238:438, 1990). We perform a very accurate search of X-rays from the Pauli-forbidden atomic transitions of electrons in the already filled 1S shells of copper atoms. Although the experiment has a very simple structure, it poses deep conceptual and interpretational problems. Here we (...) describe the experimental method and recent experimental results, which we interpret in the framework of quon theory. We also present future plans to upgrade the experimental apparatus using Silicon Drift Detectors. (shrink)

Recognition of the identity of familiar faces in conditions with poor visibility or over large changes in head angle, lighting and partial occlusion is far more accurate than recognition of unfamiliar faces in similar conditions. Here we used a visual search paradigm to test if one class of social cues transmitted by faces – direction of another’s attention as conveyed by gaze direction and head orientation – is perceived more rapidly in personally familiar faces than in unfamiliar faces. We found (...) a strong effect of familiarity on the detection of these social cues, suggesting that the times to process these signals in familiar faces are markedly faster than the corresponding processing times for unfamiliar faces. In the light of these new data, hypotheses on the organization of the visual system for processing faces are formulated and discussed. (shrink)

This study uses a Corpus Assisted Discourse Studies methodology to provide the first systematic analysis of how trust is discursively constructed in crypto-drug markets. The data come from two purpose-built corpora. One comprises all the forum messages posted on the flag ship crypto-drug market Silk Road during the years in which it traded on the hidden net. The other corpus comprises all the reports published by the United Nations Office on Drugs and Crime during the same period. Our analysis of (...) trust focuses on the identities of those buying and selling drugs. The findings reveal that the Silk Road community members regularly discussed vendors’ identities alongside a continuum of trust–risk calculation, explicitly identifying both ‘good’ and ‘bad’ practices and hence engaging in self-regulatory discourses, and mainly constructed drug users’ identities in relation to values of expertise, integrity and benevolence. The findings also suggest that hard law enforcement activity, such as crypto-drug market closure, may encourage technological innovation within these markets. Moreover, our results show a disconnect between the discursive reality of the policy-making documents we examined and the very crypto-drug markets that they seek to legislate. (shrink)

Background: Mentalizing, the mental capacity to understand oneself and others in terms of mental states, has been found to be reduced in several mental disorders. Some studies have suggested that eating disorders may also be associated with impairments in mentalizing. The aim of this work is to investigate the possible presence of mentalizing subtypes in a sample of patients with EDs.Method: A sample of patients with eating disorders completed a battery of measures assessing mentalization and related variables, including the Reflective (...) Functioning Questionnaire, the Difficulties in Emotion Regulation Strategies, the Interpersonal Reactivity Index. Clinicians rated patients in relation to imbalances in different dimensions of mentalization to prementalizing modes and attachment style by using the Mentalization Imbalances Scale, the Modes of Mentalization Scale, and the Adult Attachment Questionnaire. A latent profile analysis was conducted to test the possible presence of different subgroups. MANOVA was used to test the possible differences between the four mentalizing profiles in relation to emotion dysregulation, empathy, and adequate and impairments in mentalizing.Results: The latent profile analysis suggested the presence of four different profiles in relation to impairments in the dimensions of mentalization: affective/self/automatic imbalances, external imbalance, cognitive/self/automatic imbalances, and cognitive/other/automatic imbalances. Patients belonging to profile 1 are characterized by the prevalence of affective mentalization that overwhelms the capacity to reflect on mental states with an imbalance on the self-dimension; profile 2 patients are excessively focused on the external cues of mentalization; profile 3 patients are characterized by an over-involvement on the cognitive and self-facets of mentalization, with an impairment in adopting the other mind perspective; and profile 4 patients have similar impairments compared to profile 3 patients but with an excessive focus on others and deficits in self-reflection. These profiles were heterogeneous in terms of EDs represented in each group and presented significant differences on various variables such as attachment style, emotion dysregulation, empathy, interpersonal reactivity, and reflective function. This study represents, so far, the first work that confirms the presence of different mentalizing patterns in ED patients.Conclusions: ED patients can be classified in relation to impairments in different dimensions of mentalization above and beyond ED diagnosis.

This volume brings together world-leading scholars on the thought of Averroes, the greatest medieval commentator on Aristotle but also a major scholar of Islam. The collection situates him in his historical context by emphasizing the way that he responded to the political situation of twelfth-century Islamic Spain and the provocations of Islamic theology. It also sheds light on the interconnections between aspects of his work that are usually studied separately, such as his treatises on logic and his legal writings. Advanced (...) students and scholars will find authoritative and insightful treatments of Averroes' philosophy, tackled from multiple perspectives and written in a clear and accessible way that will appeal to those encountering his work for the first time as well as to anyone looking for new critical approaches to Averroes and his thinking.

Nella notazione musicale ancora alla metà del Duecento i valori di durata sono organizzati in raggruppamenti di piedi ritmici costruiti su un minimo di durata , che è anche unità di misura del tempo musicale, corrispondente alla sillaba. Con la nascita della notazione mensurale, verso la fine del Duecento, ma soprattutto in seguito all'evoluzione della prassi compositiva, nei primi decenni del Trecento fu necessario ridefinire il rapporto tra tempo, minimo di durata e unità di misura. I musici al di qua (...) e al di là delle Alpi ovviarono diversamente dando vita a due sistemi musicali e notazionali, italiano e francese, differenti proprio nei loro presupposti teorici. In ambito italiano Marchetto da Padova dimostra come l'unità di misura del tempo musicale non coincida con il minimo di durata in senso assoluto, ma con ciò che è minimo all'interno del genere musicale: pur chiamandosi ancora breve, l'unità di misura nel sistema notazionale italiano può arrivare a contenere fino a dodici suoni. L'articolo mette a fuoco come Marchetto da Padova giunga alla definizione dell'unità di misura del tempo musicale nel suo trattato Pomerium e mostra le implicazioni di tale presupposto sulla prassi compositiva e la specificità del repertorio medesimo rispetto al coevo repertorio francese. During the latter half of the thirteenth century and particularly in the the fourteenth century, the mensural notation redefines the relationship between tempo, beat and temporal units. Italian and French musicians use different notational systems each with their own theoretical assumptions. In Italy Marchetto da Padova demonstrates that the beat does not coincide with the minimum in a quantitative understanding of musical time, but with the minimum in a qualitative undestanding of musical time: even it is called 'brevis', the beat in the Italian notational system can be divided up to twelve notes. The article focuses on how Marchetto of Padua explains it in his treatise Pomerium, and shows the implications of this assumption in compositional practice. (shrink)

Ever since the last century art seems to be characterized by a powerful metareflective vocation. The works of Mimmo Paladino represent an effective barrier in this deconstructive movement and allow art to preserve the memory of its own narrative vocation.

Della produzione didascalica di argomento astronomico dell’età ellenistica la tradizione manoscritta ci ha consegnato soltanto i Fenomeni di Arato, poema che sin da subito ha goduto di un vasto successo, testimoniato da riscritture, commenti e traduzioni. Poco sappiamo della poesia astronomica non aratea, di cui rimangono sparute testimonianze ed esempi frammentari, tra cui spiccano i cinque esametri sulla luna di Egesianatte (SH 466-467). Il presente contributo intende valutare la posizione di Egesianatte all’interno della poesia didascalica di argomento astronomico, prendendo in (...) considerazione le testimonianze sulla sua produzione astronomica e analizzando tanto il contesto di citazione dei versi, quanto il testo stesso dei frammenti.

Intanto, chi è Testadura? Nel 1964 Arthur C. Danto pubblica sul “Journal of Philosophy” un saggio destinato a diventare un punto di riferimento importante per l’estetica analitica del Novecento: The Artworld. Testadura è il personaggio – dal simpatico nome italiano – che incarna il punto di vista opposto a quello sostenuto da Danto. Il problema che incuriosisce il filosofo americano, spingendolo a elaborare una filosofia dell’arte per molti versi originale è, in realtà, una questione tipicame...

«Everything is what it is, and not another thing»: Roberta De Monticelli avrebbe forse potuto servirsi dell’epigrafe che George Moore pose come incipit dei Principia Ethica, nel 1922, per intitolare il suo nuovo libro. Sceglie invece un titolo che richiama Nietzsche e ciò che il suo pensiero ha rappresentato, per porre l’accento su un disegno teorico che percorre tutto il libro: tornare al di qua del nietzschianesimo, del suo scetticismo epistemologico e assiologico, per riprenderci non solo...

The present study had two goals: to test the validity of Planned Happenstance Career Inventory in the Italian context and to explore the relations between PHC skills and vocational identity processes within a sample of 472 undergraduate students attending university in the southern of Italy. Moreover, we examined relations between the PHCI and measures of vocational identity processes. With regard to the first goal, results show that for the Italian version of the instrument was confirmed the multifactor structure of the (...) original version. The multi-group analyses showed that invariance between genders is supported. Convergent validity and divergent validity of the measure were reported. Concerning the second goal, the skills of planned happenstance show different associations with Vocational Identity Dimensions. As hypothesized, the exploration and commitment dimensions of vocational identity status are positive related to Planned Happenstance Skills. These findings suggest implications for career guidance and counseling. (shrink)

It is known how much of the work that Arthur Danto has dedicated to the philosophy of art has concerned the concept of representation and, specifically, the concept of artistic representation. The basic thesis that Danto developed starting from The Artworld (1965) consists in the idea that art should be considered as a particular type of representation, as opposed to what Plato had suggested, who considered it as a form of mimesis of reality. The article will show how this Dantian (...) thesis, which is based on the notion of artistic representation exhibited by Friedrich Nietzsche in the Birth of Tragedy, firstly hides a partial misunderstanding of Nietzsche's theses, and secondly reveals a philosophical error equal to and contrary to that made by Plato. We will also show how art is often a form of mimesis and how different types of mimesis are in fact compatible with artistic representation. Finally, we will show how mimesis and representation offer different forms of knowledge that belong to the art of all times. (shrink)

L'articolo si propone di leggere il paradigma spaziale, oggi dominante, basato sui flussi, le reti, il networking, come elemento di un discorso complesso volto a fornire legittimazione epistemologica agli effetti di ristrutturazione economico-spaziale indotti dalla globalizzazione. Un paradigma il cui funzionamento opera esclusioni, selezioni, tagli, e che forse costituisce lo strumento di nuove politiche governamentali. Il termine "plasma", introdotto da Latour per indicare ciò che eccede tale modellizzazione viene qui declinato in un concetto più classico, quello di plebe. In Hegel (...) come in Foucault, la plebe è uno scarto sociale che dipende dalle forme di organizzazione materiale e ideale che la società liberale di volta in volta assume, e che problematizza il centro politico del discorso sulla città proprio perché ad esso irriducibile.
