In his article Grush proposes a potentially useful framework for explaining motor control, imagery, and perception. In our commentary we will address two issues that the model does not seem to deal with appropriately: one concerns motor control, and the other, the visual and motor imagery domains. We will consider these two aspects in turn.

Depressive symptoms are characterised by reduced cognitive control. However, whether depressive symptoms are linked to difficulty in exerting cognitive control in general or over emotional content specifically remains unclear. To better differentiate between affective interference or general cognitive control difficulties in people with depressive symptoms, we employed a non emotional (cold) and an emotional (hot) version of a task-switching paradigm in a nonclinical sample of young adults (N = 82) with varying levels of depressive symptoms. Depressive symptoms were linked to (...) greater difficulties in exerting cognitive control in complex situations (mixed-task blocks) compared to simple and semiautomatic situations (single-task blocks) in both task versions. Moreover, greater depressive symptoms were associated with longer latencies in the emotional version of the task across all trial types. Thus, the emotion-specific effect was not modulated by the degree of cognitive control required to perform the task. In sum, depressive symptoms were characterised by a general difficulty to exert cognitive control in both emotional and non emotional contexts and by greater difficulty in even simple attentional processing of emotional material. This study granted novel insights on the extent of cognitive control difficulties in emotional and non emotional contexts for people with depressive symptoms. (shrink)

Understanding the causes of maize landrace loss in farmers’ field is essential to design effective conservation strategies. These strategies are necessary to ensure that genetic resources are available in the future. Previous studies have shown that this loss is caused by multiple factors. In this longitudinal study, we used a collection of 93 maize landrace accessions from Morelos, Mexico, and stored at the International Maize and Wheat Improvement Center (CIMMYT) Maize Germplasm Bank, to trace back to the original 66 donor (...) families after 50 years and explore the causes for why they abandoned or conserved their seed lots. We used an actor-centered approach, based on interviews and focus group discussions. We adopt a Multi-Level Perspective framework to examine loss as a process, accommodating multiple causes and the interactions among them. We found that the importance of maize landrace cultivation had diminished over the last 50 years in the study area. By 2017, 13 families had conserved a total of 14 seed lots directly descended from the 1967 collection. Focus group participants identified 60 accessions that could still be found in the surrounding municipalities. Our findings showed that multiple interconnected changes in maize cultivation technologies, as well as in maize markets, other crop markets, agricultural and land policies, cultural preferences, urbanization and climate change, have created an unfavorable environment for the conservation of maize landraces. Many of these processes were location- and landrace-specific, and often led to landrace abandonment during the shift from one farmer generation to the next. (shrink)

Cancer diagnosed during pregnancy is a rare event. The most common type of malignancy diagnosed in pregnant women is breast cancer, whose incidence is expected to raise in the next future due to delayed childbirth, as well as to the increased occurrence of the disease at young age. Pregnant women diagnosed with breast cancer are exposed to multiple sources of stress, which may lead to poorer obstetric outcomes, such as preterm birth and low birth weight. In addition, pregnancy involves physiological (...) changes in the breasts that may blur the signs of cancer, with delayed diagnosis and poor prognosis. However, the lived experience of these women was investigated in very few studies. Given this scenario, we conducted this qualitative study to describe and understand women’s subjective experience of being diagnosed with breast cancer during pregnancy. The study was conducted following the principles of Interpretative Phenomenological Analysis. Participants were five women with breast cancer diagnosed during pregnancy, purposefully recruited at a public hospital during medical visits and interviewed at treatment initiation. The interview transcripts were analyzed using thematic analysis. The textual analysis led to the identification of three main themes related to: the emotional storm experienced after cancer diagnosis, and the importance of receiving appropriate information and being focused on treatment decisions; physical changes and comparisons with healthy women, associated with feelings of sadness and inadequacy; being positive, feeling free to disclose all kinds of emotions, religion and spirituality as sources of strength. The paradoxical coexistence of pregnancy and cancer represents a stressful experience for women and their loved ones. Adopting a systemic perspective may be important to understand the effects of such a complex condition, also considering its impact on healthcare workers. (shrink)

The author intends to show how the criticism of Maurizio Ferraris to the correspon-dence of ontology and epistemology, which developed in the modern age, does not consider that the Thought of the transcendentalism is not the thought of the everyday language but rather a limiting concept. Therefore, the fair criticism to the pragmatism and to the post-modernism in the name of the “reality principle” cannot involve the ideas of the so-called idealists (Kant, Hegel, Gentile, Croce): to conceive the reality as (...) history, as the idealists do, has important ethical implications.

Questo articolo descrive una investigazione condotta su un campione non probabilistico di alunni di scuola primaria della provincia di Siracusa (Italia), durante la quale è stato sperimentato un metodo didattico elaborato sulla scorta di alcuni modelli di musicoterapia e dalle riflessioni su alcune esperienze realizzate a scuola. L’analisi testuale comparativa ha consentito di rilevare che il metodo didattico proposto, se adottato con criteri ben definiti (procedure e musiche classiche selezionate), potrebbe aiutare gli insegnanti a strutturare ambienti didattici inclusivi e funzionali (...) per potenziare lo sviluppo delle competenze della comprensione del testo degli alunni.

In the last few years, an old question seems to have returned to the forefront among philosophers: is it improper to speak about national philosophical traditions? Or is it legitimate, for example, to identify a precise Italian philosophy and distinguish it from a French one? In the case it is legitimate, is it also beneficial to speak in such terms? Which are the risks and advantages of using national or territorial criteria as a principle for identifying different traditions of philosophical (...) thought? The essay analyses these questions, going through the main stages of the Italian philosophical historiography from Bertrando Spaventa’s theory of the “European circulation of Italian thought” to the “Italian Theory” of Roberto Esposito.

È possibile delineare due filoni interpretativi sul _Hayy b. Yaqzān_ (_Il vivente, figlio del desto_) di Ibn Tufayl: secondo l’uno, l’opera è uno sguardo realistico su un solitario in una società corrotta e si ispira agli insegnamenti della _Repubblica_ di Platone; secondo l’altro, l’opera ritrae un ideale puro e astratto di vita ascetica e insiste sull’imperativo morale dell’isolamento. Tuttavia entrambe queste interpretazioni precludono qualsiasi possibilità di felicità per l’uomo o per il filosofo all’interno di una società. In altre parole, tendono (...) a interpretare _Hayy b. Yaqzān_ come un tentativo di dimostrare che l’uomo non sia sociale o politico. La perfezione intellettuale e spirituale ricercata attraverso l’isolamento non può, a mio parere, essere separata da uno scopo pratico. L’isolamento del filosofo non viene praticato per distinguersi dalle società imperfette. Al contrario, tale isolamento è intrapreso per condurlo ad una realizzazione più alta e propriamente pratica. Su questa base, sostengo nell’articolo che l’uomo di Ibn Tufayl sia paragonabile allo ζῷον πολιτικόν aristotelico. Attraverso un confronto tra il _Hayy_ di Ibn Tufayl e lo ζῷον πολιτικόν di Aristotele vedremo come Ibn Tufayl si serva dell’_animale sociale/politico_ arabo (_hayawān insī _o _madanī_) di al-Fārābī e lo trasponga dal dominio della città a quello dell’individuo. Analizzando alcuni passaggi chiave, è possibile chiarire come il concetto di ζῷον πολιτικόν sia entrato nella filosofia araba e in particolare nella concezione di uomo di Ibn Tufayl attraverso il virtuoso di al-Fārābī e il solitario di Ibn Bājja. Prevailing academic views on Ibn Tufayl’s _Hayy b. Yaqzān_ (_Living, the Son of Wakeful_) fall into two camps: either the work is a realistic look at an isolated human being amidst a morally bankrupt population and harks back to the teachings of Plato’s _Republic_, or it portrays a pure and abstract ideal of the spiritual life in the footsteps of the natural first man, and insists on the moral imperative of isolation. The difficulty with both interpretations is that they preclude any possibility of happiness for the human person or the philosopher living in a society. In other words, they tend to interpret _Hayy b. Yaqzān_ as an attempt to demonstrate that the human is not essentially social or political. However, the intellectual and spiritual perfection sought through isolation cannot, in my opinion, be separated from a practical purpose. The isolation of the philosopher is not undergone to distinguish himself from imperfect human societies. On the contrary, such isolation is undertaken in order to lead one to a higher, and properly practical accomplishment. On this basis, I argue in this paper that Ibn Tufayl’s man is comparable to the Aristotelian ζῷον πολιτικόν. Through a comparison of Ibn Tufayl’s _Hayy_ and Aristotle’s ζῷον πολιτικόν we shall see how Ibn Tufayl reuses the Arabic _social/political animal_ (_hayawān insī_ or _madanī_) of al-Fārābī and transposes it from the domain of the city to that of the individual. By analysing some key passages, it becomes possible to illustrate how the concept of ζῷον πολιτικόν has entered Arabic philosophy, and particularly in Ibn Tufayl’s conception of man through the lenses of al-Fārābī’s virtuous and Ibn Bājja’s solitary man.

Purpose of the essay is to outline the theoretical roots of Ricci’s museum and publishing policies, inscribed within a visual disclosure plan of our archaeological artistic heritage identified as the pivot on which to build a collective identity of our nation at the dawn of its unification. These policies are closely linked to Ricci’s conception of art, recognized by himself as the formal expression of a – both individual and collective – historical feeling, finding its immediate grip on the public (...) in the optical vividness of its representational form. This conception, however, finds its aesthetic-anthropological foundation in a book belonging to Ricci’s early production: “The art of children”. (shrink)

Questo lavoro segue la vicenda di una legge dalla formulazione ad opera di Torricelli alle prime risposte che ebbe in sede di fondazione dinamica. La velocità dell’acqua in efflusso da un serbatoio costantemente pieno è proporzionale alla radice quadrata dell’altezza di carico. Forte della concettualizzazione galileiana, Torricelli introdusse la legge all’interno di un ammirevole assetto geometrico.

According to a fragment of Porphyry (410 F Smith = 80 B 2 DK), containing a dialogue on the theme of plagiarism, Plato made use of the same arguments as Protagoras’ Περὶ τοῦ ὄντος against monistic thinkers, most likely the Eleatics. My paper aims to analyse Porphyry’s testimony to assess some aspects of Protagoras’ reflection on being through a comparison with parallel sources, in particular Plato’s dialogues (Theaetetus, Euthydemus, Sophist, Parmenides). I conclude that it is plausible to suppose that, within (...) the framework of a more general reflection on ὀρθοέπεια, Protagoras viewed the notion of being in Περὶ τοῦ ὄντος from a linguistic perspective.

Perché quella faccia triste, lettore? Non sapere ti rende infelice. Non sai nulla di quello che ti circonda: non sai come fa a volare l'aereo che ti porterà a Londra, non sai quante zampe ha una Pseudoiulia cambriensis, come funziona il wi-fi, quanta acqua c'è nell'Oceano Atlantico. Sai cosa vuol dire entelechìa? Quanti capelli abbiamo in testa? Hai mai provato a contare tutte le stelle? No, ma l'ha già fatto l'astronomo Ipparco, e le notizie non sono buone: non potremo saperlo (...) mai. Più cerchi di trovare risposte più si formulano ulteriori domande. Ogni informazione è superata nel momento in cui la ricevi, ogni novità è storia vecchia. Grazie a Internet puoi sapere dove sono i tuoi amici in questo momento, con chi sono, cosa fanno. Ma ti interessa davvero? Se digiti parole a caso su Google (“kefYDl9”) qualche risultato verrà fuori di sicuro. Ma saperlo potrà farti vivere meglio? Hai uno sguardo sconsolato, lettore. Non sai che potresti vivere anche senza tutte queste conoscenze. Tu sei Prometeo, prigioniero del fuoco. Sei il fratello spirituale di Friedrich Nietzsche. Se fossi un personaggio di Game of Thrones saresti il Guardiano della Notte Jon Snow, il paladino che lotta trafitto dal dolore di non conoscere né il suo passato né il suo destino. Non lo conosci, ma forse non hai mai voluto saperlo. Anche sapere ti rende infelice: sai benissimo che più cose riuscirai a conoscere più diventerai ignorante. È il paradosso dell'ignoranza: non sapremo mai cosa esattamente sappiamo, e sappiamo solamente ciò che pensiamo di sapere. (shrink)

When we witness a great actor, musician, or sportsperson performing, we share something of their experience. Only recently has it become clear just how this sharing of experience is realised within the human brain. 'Mirrors in the brain' provides an accessible overview of mirror neurons, written by the man who first discovered them.
