The Event Structure of Motion Perception
2004
Motion perception on the basis of optic flow is often studied using purely perceptual response paradigms such as forced choice preferences, and using straightforward motor responses such as simple stereotypical reaction times. Here we argue for a more complex perspective that takes into account the event structure of ecological motion perception. In particular, we hope to convince the reader that the would-be perceptual response to a motion stimulus is noticeably modified be the type of response that is required from the actor. We will argue that our actions modify our perception and more precisely, that the planning component of intended actions influence processing of time critical motion…
Has palaeontology answers for some current environmental problems?
2021
History as an irreversible process has no role from a uniformitarian point of view in geology and palaeobiology. Contingency is another trait of history and particle palaeontology has its foundation on such principles. However, new approaches in physics and the theory of systems point out the need to consider a time arrow. Moreover, chance and necessity are interwoven in synergetics and self-organization theory and there may be some possibility of prediction. The global biota has a history resulting from a process of self-organization. A rich fossil record was produced during the Phanerozoic times and this fossil record shows us how life overcame several important crisis. A clear understand…
Corrigendum to “Personal protective equipment and intensive care unit healthcare worker safety in the COVID-19 Era (PPE-SAFE): An international surve…
2021
The authors regret errors were present in the published article. Counts of some of the adverse events were erroneous. Changes to the text include. Last sentence of the abstract should read. Adverse effects of PPE included heat (1266, 51%), thirst (1174, 47%), pressure areas (1088, 44%), headaches (696, 28%), Inability to use the bathroom (661, 27%) and extreme exhaustion (492, 20%). All but pressure areas were associated with longer shift durations. Last sentence of the results section of the manuscript should read. All but pressure areas were associated with longer duration of shifts wearing PPE (Table 4). Table 1 the total number of community/urban type of hospital should read 740 instead…
Del fantastico architettonico
2012
L’interesse di Caillois per il fantastico è stato declinato nella sua opera in moltissime varianti: da quello più tradizionale dell’arte e della letteratura a quello del mondo animale e minerale, fino a quello urbano La mitologia della città di Parigi ritorna con forza maggiore nelle due tarde opere cailloisiane, Petit guide du XVe arrondissement à l’usage des fantomes (1977) e Apprentissage de Paris (1978), nella forma di una scrittura non più meramente saggistica ma romanzesca e/o autobiografica. L’architettura destinata ad accogliere i fantasmi è dunque espressione del fantastico architettonico, per i suoi oggetti, per la sua modalità di presentazione e per lo sguardo che su di essa vi e…
Abelian Powers and Repetitions in Sturmian Words
2016
Richomme, Saari and Zamboni (J. Lond. Math. Soc. 83: 79-95, 2011) proved that at every position of a Sturmian word starts an abelian power of exponent $k$ for every $k > 0$. We improve on this result by studying the maximum exponents of abelian powers and abelian repetitions (an abelian repetition is an analogue of a fractional power) in Sturmian words. We give a formula for computing the maximum exponent of an abelian power of abelian period $m$ starting at a given position in any Sturmian word of rotation angle $\alpha$. vAs an analogue of the critical exponent, we introduce the abelian critical exponent $A(s_\alpha)$ of a Sturmian word $s_\alpha$ of angle $\alpha$ as the quantity $A(s_\a…
Bayesian Checking of the Second Levels of Hierarchical Models
2007
Hierarchical models are increasingly used in many applications. Along with this increased use comes a desire to investigate whether the model is compatible with the observed data. Bayesian methods are well suited to eliminate the many (nuisance) parameters in these complicated models; in this paper we investigate Bayesian methods for model checking. Since we contemplate model checking as a preliminary, exploratory analysis, we concentrate on objective Bayesian methods in which careful specification of an informative prior distribution is avoided. Numerous examples are given and different proposals are investigated and critically compared.
Personal protective equipment and intensive care unit healthcare worker safety in the COVID-19 era (PPE-SAFE): An international survey
2020
Purpose To survey healthcare workers (HCW) on availability and use of personal protective equipment (PPE) caring for COVID-19 patients in the intensive care unit (ICU). Materials and method A web-based survey distributed worldwide in April 2020. Results We received 2711 responses from 1797 (67%) physicians, 744 (27%) nurses, and 170 (6%) Allied HCW. For routine care, most (1557, 58%) reportedly used FFP2/N95 masks, waterproof long sleeve gowns (1623; 67%), and face shields/visors (1574; 62%). Powered Air-Purifying Respirators were used routinely and for intubation only by 184 (7%) and 254 (13%) respondents, respectively. Surgical masks were used for routine care by 289 (15%) and 47 (2%) for…
Davide e Golia. Giuseppe Antonio Borgese e la traiettoria americanista di un esule antifascista
2019
Giuseppe Antonio Borgese was one of the anti-fascist intellectuals who, around the Thirties of the XX Century, let themselves be involved by the American myth. Although inspired by democratic ideals mixed with a profound sense of Risorgimento and libertarian patriotism, he was near the nationalist and interventionist ideology. The decisive turning point in Borgese's life took place during the years in which the dictatorship and the regime of censorship imposed by Fascism, became ever more alive and dominant, causing him to develop the idea of leaving Italy for the United States. Beyond the contradictories relationships that bound him to the two Countries, Borgese, unable to recognize his ho…
L’Aula Magna dell'Università di Palermo: cronistoria di un cantiere decorativo (1928-1938)
2020
Situata all'interno dell'odierno Dipartimento di Giurisprudenza, l'Aula Magna dell'Università di Palermo è stata progettata dall'architetto Antonio Zanca che firma nel 1929 il progetto esecutivo di un ambiente neo-settecentesco dotato di mobilio e decorazioni pittoriche sulle pareti. Nel 1934 è stato indetto un concorso nazionale per l'affidamento delle decorazioni pittoriche vinto da Arduino Angelucci e Manlio Giarrizzo cui spettano rispettivamente la volta e le pareti. Grazie alla stampa locale è possibile ricostruire - almeno in parte - le vicende di questo concorso che si colloca in un contesto nazionale fortemente attento, dopo la Triennale di Milano del 1933, al problema della decoraz…
