The diameter of cortical axons depends both on the area of origin and target
No full textIn primates, different cortical areas send axons of different diameters into comparable tracts, notably the corpus callosum (Tomasi S, Caminiti R, Innocenti GM. 2012. Areal differences in diameter and length of corticofugal projections. Cereb Cortex. 22:1463-1472). We now explored if an area also sends axons of different diameters to different targets. We find that the parietal area PEc sends thicker axons to area 4 and 6, and thinner ones to the cingulate region (area 24). Areas 4 and 9, each sends axons of different diameters to the nucleus caudatus, to different levels of the internal capsule, and to the thalamus. The internal capsule receives the thickest axon, followed by thalamus and nucleus caudatus. The 2 areas (4 and 9) differ in the diameter and length of axons to corresponding targets. We calculated how diameter determines conduction velocity of the axons and together with pathway length determines transmission delays between different brain sites. We propose that projections from and within the cerebral cortex consist of a complex system of lines of communication with different geometrical and time computing properties. © The Author 2013
Virtual vs. Standard Strike: An Experiment
No full textIn this paper we compare - in the laboratory - stoppage and virtual strike. Our experiment confirms that higher wages offered by an employer lead to considerably more costly effort provision. The number of strikes, the level of efforts and average total payoffs are higher under virtual strike than under standard strike. However, when standard strike is associated with reciprocal externalities, it induces higher effort levels, higher payoffs and an extremely reduced number of strikes than virtual strike. It is unclear whether this behavior re?ects reciprocity or other forms of social preferences. However our results might explain why standard strikes rather than virtual ones are generally adopted by workers.virtual strike, cooperation, reciprocity, fairness, experiments
La scena trasformata. Adattamenti neoclassici di Shakespeare
No full textThe first Italian study thoroughly analyzing the phenomenon of transforming Shakespeare’s plays, which took place from the Restoration to the end of the eighteenth century. The aim of the adaptors was that of making the drama of the past “fit” for a new audience and a new theatre as well as of “amending” what was considered faulty in Shakespeare, according to the neoclassical aesthetics recently imported from France. The book considers both the different kinds of transformation the texts underwent, and the reasons for the revival of the original plays on the eighteenth-century English stage; a revival which was linked to the growing consecration of their author as the national poet
COMPOSIZIONE E NUOVI POTERI/DOVERI DELL'ORGANO DI CONTROLLO E DEL REVISORE NELLE S.R.L., TRA VECCHI E NUOVI INTERROGATIVI
No full textIl contributo si concentra sulle principali novità riguardanti il collegio sindacale nelle s.r.l. introdotto dalla riforma della legge fallimentare italiana (il cosiddetto Codice della Crisi e dell'Insolvenza - CCII). L'autore si propone di analizzare sia la composizione (ovvero la struttura) del collegio sindacale sia le nuove regole e compiti che ne arricchiscono i doveri di la vigilanza (v. art. 379 CCII che ha sostanzialmente modificato l'art. 2477 cc). L’Autore evidenzia il quadro sistematico risultante: partendo dagli specifici profili organizzativi del collegio sindacale nelle s.r.l. e proseguendo analizzando i diversi compiti\doveri reattivi in caso di crisi o di pre-crisi introdotti dall'articolo 14 CCII. Nel nuovo sistema di allerta, il collegio sindacale riveste un ruolo fondamentale: la sua attività di vigilanza e controllo ex ante sulla gestione gli consente di svolgere di fatto un importante ruolo di principale destinatario di eventuali segnali di allarme; in particolare devono segnalare tempestivamente un allarme in ogni momento di crisi, al fine di trovare soluzioni alla crisi attuale. L'autore evidenzia quindi le diverse implicazioni che coinvolgono il ruolo dei sindaci nella governance delle s.r.l. e il loro rapporto con l’audit interno e la direzione.The paper focuses on the main innovations regarding the board of statutory auditors in s.r.l. introduced by the Italian Bankruptcy Law reform (the so-called Crisis and Insolvency Code- CCII).The author aims to analyze both the composition (i.e. the structure) of the board of statutory auditors and the new rules and duties that enriches their supervisory
action introduced by Article 379 CCII (which largely modified Article 2477 of the Civil Code). The author highlights the resulting framework: starting from the specific organizational profiles of statutory auditor’s board in s.r.l. and continuing by analyzing the various reactive interventions in case of crisis or emerging crisis, introduced by Article 14 CCII. In the new warning system, the board of statutory auditors plays a fundamental role: its ex-ante supervisory and control activities over management allow it to effectively play an important role as main recipient of any crisis warning signs; in particular, they have to point out a warning in any moment of crisis promptly, in order to find solutions to the current crisis.Therefore, the author points out the various implications involving the role of statutory auditors in the governance of s.r.l. and their relationship with internal audit and management
Scrotal dartos-fascio-myo-cutaneous flaps for penis elongation after catastrophic iatrogenic skin shaft sub-amputation: A case of recovery using an extremely adaptable flap
No full textAbstractIntroductionGenitalia are linked to self-esteem and male sexual identity, especially among young men, who sometimes require a surgical procedure to acquire more confidence. Among the surgical procedures requested for aesthetical purposes, circumcision is one of the most popular. Although it can be considered to be a simple surgical practice, it may cause severe complications such as penile skin necrosis.Presentation of caseWe report a case of a catastrophic situation after a circumcision performed on a 27-year-old HIV positive man resulted in a drastic reduction in the length of the penile shaft due to extensive skin loss; this was subsequently restored using dartos-fascio-myo-cutaneous flaps. Primary healing occurred in 10days. No infection, dehiscence or flap ischemia were reported. Donor site morbidity was minimal. An adequate aesthetical appearance and satisfactory functional results were obtained.Discussion and conclusionVarious techniques are available for penile skin covering, such as skin grafts or cutaneous flaps. The skin of the scrotum seems to be the most suitable tissue to be used to reconstruct the skin covering of the shaft as it is the most similar. Dartos-fascio-myo-cutaneous flap is a single stage procedure that is easy and safe to perform. It can provide satisfactory cosmetic and functional results, offering a large amount of tissue, with minimal donor site morbidity
Cognitive Biases and Gaze Direction: An Experimental Study
No full textThis paper investigates the validity of the model of dual processing by means of eyetracking methods. In this theoretical framework, gaze direction may be a revealing signal of how automatic detection is modified or sustained by controlled search. We performed an experiment by using a stylized decisional framework, i.e. informational cascade, proposed by economists to investigate the rationality of imitative behavior. Our main result is that automatic detection as revealed by gaze direction is driven by mechanisms that are dependent on cognitive biases. In particular, we find significant statistical correlation between subjects’ first fixation and their revealed patterns of choice. Our findings support the hypothesis that the process of automatic detection is not independent on cognitive processes.informational cascades, overconfidence, eye-tracking, information processing, cognitive biases
Giocare a scacchi con la morte. L'Oriente come investigazione impossibile in "René Leys"
No full text"Oriente, storia di una figura nelle arti occidentali" opens the new series "Studi Inter Artes" books of the association Sigismondo Malatesta. The book consists of two volumes; the second volume, prefaced by Loretta Innocenti, focuses on the art and literature between turn-of-the-century exoticism and the present experiences. Zecchi's "Giocare a scacchi con la morte" is a vast analytical study: it shows the set of mirrors and duplications in a great "chinese" novel of Segalen, “René Leys”. The author sees China before the Revolution through the eyes of his young heroes and ironic voice and anonymous first-person narrator
Voting by Ballots and Feet in the Laboratory
No full textThis paper provides laboratory evidence on the efficiency-enhancing properties of the Tiebout model as a decentralized system of public goods provision. Tiebout (1956) shows that if a sufficient number of local communities exist to accommodate different types of preferences, individuals sort themselves in a way that provides an efficient allocation of public goods and taxes. Our experiment aims to disentangle the effect of voting participation and is composed of two treatments. In the non-participation treatment, local public good provision is chosen by only one subject, while the other members of the community can only stay in or move to another community. In the participation treatment, all the community members have the right to vote as well as to move to another community and collective decisions are taken by majority rule. Our findings show that social welfare is greater in the participation than in the non-participation treatment. We conclude that voting with one’s feet increases efficiency if all the community members vote and that the influence of voting participation on the allocation of local public goods should be taken into account to assess the viability of the Tiebout model.Tiebout model, local public goods, voting participation, federalism, experiment.
Storie di navi, di case, di cose… L’opera di Roberto Innocenti e la capacità di vedere/narrare oltre l’umano
No full textThis article analyses the work of the author and illustrator Roberto Innocenti in an ecocritical and ecomaterialist perspective. All the books for children created by Innocenti over a forty-year long career (1980s–2020s) are characterized by a passionate attention for things, objects, settings, materials, brought to the forefront and depicted in an iperrealistic way, while human beings are represented as small and distant entities, i.e.: as part of the varied tissue of forms, presences and stories of which the world is made. This propensity to attribute importance and meaning to the non-human world, and especially to ‘things’, is crucial, according to the thinkers of Ecocriticism and New Materialism. After centuries of anthropocentrism, an epistemic shift is necessary to create a new balance between man and environment, mind and matter, subject and object, and this shift can be found in Innocenti’s books, whose narrative/visual strategies succeed in representing reality as a multilayered dimension full of vibrant matter, inextricably human and non-human.L’articolo analizza in ottica ecocritica ed eco-materialista l’opera dell’autore e illustratore Roberto Innocenti. Tutti i libri per l’infanzia che Innocenti ha realizzato (dagli anni Ottanta a oggi) si impongono per un’attenzione appassionata alle ‘cose’, agli oggetti, agli ambienti, agli sfondi, portati in primo piano e iper-realisticamente resi assai più di quanto non accada ai personaggi umani, immancabilmente raffigurati come piccoli e lontani, come parte del variegato tessuto di forme, presenze e storie di cui si compone il mondo. Questa propensione a riconoscere importanza e significatività al non-umano, a fare diventare quello il focus della rappresentazione/narrazione è cruciale per i teorici dell’Ecocriticism, e ancor più del New Materialism, per i quali, dopo secoli di antropocentrismo, è necessario un nuovo paradigma epistemologico capace di ripristinare un equilibrio, in Occidente infranto, fra uomo e ambiente, mente e materia, soggetto e oggetto. Nei libri di Innocenti la realtà è mostrata come dovrebbe sempre essere intesa, per gli studiosi del Post-umano: come una dimensione multiforme, relazionale, composta di vibrante materia, sia essa umana o non-umana
