For a simple set of observables we can express, in terms of transition probabilities alone, the Heisenberg uncertainty relations, so that they are proven to be not only necessary, but sufficient too, in order for the given observables to admit a quantum model. Furthermore distinguished characterizations of strictly complex and real quantum models, with some ancillary results, are presented and discussed.

Il saggio vuole essere una riconsiderazione storico-teorica del modo di fare storiografia filosofica. Attraverso le critiche mosse da Francesco Bacone e Giordano Bruno al modello storiografico aristotelico, e quelle avanzate da Filippo Masci alla linea storiografica Hegel-Spaventa-Maturi-Gentile, si vuole evidenziare come sia sempre più avvertito un certo fastidio per una storia della filosofia teoreticamente orientata. Per una storia della filosofia convinta, cioè, dell’esistenza di una sola vera filosofia precedente in una direzione obbligata, al fine di realizzare un telos che, pur (...) riconosciuto a posteriori, è prefigurato. Rispetto a questo tipo di storiografia sembra da preferire il modello di storia della filosofia di tipo storico , capace di assumersi il compito fondamentale di riconoscere, approfondire e ricostruire l’originalità di pensieri di soggetti storici concreti, di pensieri degni di essere studiati nella loro autonomia e, quindi, di essere messi in correlazione con pensieri personali di altri soggetti pensanti, altrettanto liberi ed originali.

Benedetto Croce was a keen reader of the Italian works of Giordano Bruno when Giovanni Gentile published the Dialoghi metafisici e morali in 1907-1908. Just like his mentor Francesco De Sanctis, Croce sees Bruno as "a great thinker" and "a great writer". What he attaches great value to above all is Bruno as a philosopher deeply engaged in distinguishing between science and philosophy and combating the Aristotelians of the Renaissance. He used Bruno in his own fight against the "Aristotelians" of (...) his age: the Neo-Kantians. In his interpretation of the Italian Renaissance as the age of rationalism, whose main thread was soon broken, Croce puts Bruno and Campanella among the «few scattered and scared apostles of the future» who continued to weave the thread of rationality, later taken up by Vico and Giannone and, finally, by the Italian Risorgimento, starting with the Neapolitan patriots of 1799. When he defined the Italian Renaissance as the historical age of the emersion of rationality and of a true break the tradition, Croce made use of the fundamental intuition of Spaventa and of some of the latter’s disciples. They had stressed in the name of Bruno the sharp break between the Middle Ages and Renaissance philosophy while Croce here came closest to the philosopher from Nola, who had made a trenchant critique of the biblical myth of the "golden age".

Various notions of plausibility are used in cognitive science to argue for or against the “goodness of theories.” However, plausibility remains poorly understood and difcult to analyze. We review debates in the philosophy of science on uses of plausibility in the assessment of novel scientifc theories as well as recent attempts to formalize, reform, or eliminate specifc notions of plausibility. Although these discussions highlight important concerns behind plausibility claims, they fail to identify viable notions of plausibility that are sufciently diferent (...) from other criteria of “good theory,” such as prior probability or external coherence. We survey uses of plausibility in linguistics and cognitive science, confrming that plausibility is often a proxy for other criteria of good theory. We argue that the need remains for concepts of plausibility that can be employed to assess the quality of proposals at the early stages of theory development when other criteria are not yet applicable. We identify two such notions: one relating to formal constraints on theories and another capturing initial epistemic consensus, if not necessarily convergence on the truth, about the target system in a community of inquiry. We briefy assess the specifcity and added value of these notions of plausibility relative to other criteria for good theory. (shrink)

Il saggio ha come oggetto di riflessione quella struttura portante della vita, dell'esperienza umana che č la speranza. Come l'angoscia e l'attesa, essa vive nel futuro e qui viene esplorata nel campo delle relazioni umane, d'aiuto, di cura, in psichiatria, con connotazioni tipiche che si aggiungono a quelle filosofiche e teologiche sull'argomento. Quando la speranza rinasce dalle secche del mal di vivere, quando il medico stesso si č confrontato con le debolezze proprie e attraverso l'empatia si č messo anche in (...) ascolto del silenzio del paziente, del dialogare in silenzio, allora la speranza č come un ponte che ci fa uscire dalla nostra solitudine e diventa speranza creatrice.

Understanding how the chordate body plan originated and evolved is still controversial. The discovery by Spemann and Mangold in 1924 of the vertebrate organizer and its inductive properties in patterning the AP and DV axis was followed by a long gap until the 1960s when scientists started characterizing the molecular events responsible for such inductions. However, the evolutionary origin of the organizer itself remained obscure until very recently; did it appear together with the origin and radiation of vertebrates, or was (...) it a chordate affair? A recent study by Yu and collaborators,1 which analyses the expression of several organizer‐specific genes in amphioxus together with recent phylogenetic data that reversed the position of invertebrate extant chordates (e.g. urochordates and cephalochordates), indicates that the organizer probably appeared in early chordates. It likely had separate signalling centres generating BMP and Wnt signalling gradients along the DV and AP axis. The organizer was then lost in the urochordate lineage, most probably as an adaptation to a rapid and determinate development. BioEssays 29:619–624, 2007. © 2007 Wiley Periodicals, Inc. (shrink)

For over 20 years, the Schmid Training Course (STC) has offered unique opportunities for marine biology students from European universities to learn about marine model organisms. While the topics of the course have continuously changed over the years with the advent of new research techniques and discoveries, the pedagogical approach has remained largely the same – a combination of lectures, lab practicals, and field excursions. Several life science researchers, who have taught in the STC for many years, sought to bring (...) the course's pedagogical approach into the 21st century, and with the support of Erasmus+ Programme of the European Community funding, the Digital Marine project was developed. Digital Marine began in 2018 as an international partnership between the six research centers from which the STC instructors hail, and its main objective was to introduce a flipped, blended approach to learning and teaching with respect to established and emerging marine biological model systems. The Digital Marine platform, which covers 12 marine model organisms, is now publicly available. (shrink)

Although research integrity practices in institutional settings is not a new area of study, because of its foundational importance in university settings it remains a topic worthy of study. In addition, rarely are all members of the university community included as participants in studies focused upon research integrity and ethics. Thus, to add to the existent literature, the authors investigated research integrity practices in a medium-sized Midwestern polytechnic university setting, including 467 participants from across all divisions of the university community. (...) This mixed data survey study was comprised of six sections; presented is information for two sections—sample demographics and research integrity. The demographics appear reflective of those of the larger survey, as well as the university setting of study. In the research integrity section there were two parts—one qualitative and one quantitative. Implications with regard to research integrity and ethics in the institutional setting of study are presented. (shrink)

Resumen: Este texto consiste básicamente en una presentación general de la corriente filosófica del nuevo realismo surgida en 2007 y en la que participan autores europeos y norteamericanos. Un punto en común de las diversas posiciones dentro de esta corriente es el deslinde crítico frente a la filosofía posmoderna y a la filosofía moderna en general. Explico esta crítica y sus implicaciones para la posibilidad de un restablecimiento en la filosofía contemporánea del pensamiento metafísico.: This text is basically an overview (...) of philosophical new realism which emerged in 2007 and involves European and American authors. A common point to the various positions within this current is a critical detachment from postmodern philosophy and modern philosophy in general. i explain this criticism and its implications for the possibility of a restoration in contemporary philosophy of metaphysical thought.
