L’attività descritta in questo articolo si propone di stimolare, attraverso la pratica della piegatura origami, una riflessione metacognitiva sul tema dell’apprendimento e consiste in un’azione creativa che consente di sperimentare alcune delle difficoltà comuni nel percorso di studi universitario, individuando fin da subito strategie utili per affrontarle. L’esperienza, da svolgersi nelle prime settimane di lezione, mette in luce l’importanza di sviluppare un atteggiamento consapevole nei confronti dello studio e affronta due temi cruciali per l’efficacia dell’apprendimento: il ruolo della curiosità come spinta motivazionale a imparare cose nuove e l’importanza della fiducia nel docente e nelle sue proposte didattiche. In questa sede si presentano i risultati di un’applicazione nell’ambito di un corso universitario di matematica, benché l’attività, che per sua natura insiste più sul piano metodologico che non su quello strettamente disciplinare, possa essere trasferita efficacemente anche ad altri insegnamenti.

Bruno Latour – among the many ways he can be described – is one of the masters of contemporary pragmatic sociology and he has suggested many original innovations to sociology as a whole. This article aims to explore these innovations – in particular the idea of considering social action as the increasingly technoscientific result of even radically heterogeneous forces, which may or may not be associated in collaborative and alliance chains, in plural, dynamic and relational socio-technical networks, connecting human and non-human entities in carrying out a series of practical realisations in a corporeal and material world – and their possible application to apparently very different fields.

Abstract Field, petrological and LA-ICP-MS U-Pb geochronological data of metavolcanic rocks were used to interpret the petrological processes and to propose the tectonic setting for the Mundo Novo greenstone belt (MNGB) in the eastern São Francisco Craton. The metavolcanic rocks studied are metakomatiite, eastern and western metabasalts, and metadacite with subordinate metarhyolite, which host ocean floor hydrothermal alteration zones and are covered by ocean floor lithological associations composed of chemical metasedimentary rocks. Fractional crystallization and heterogeneous intraoceanic contaminations explain the mineralogical differences between the two metabasalts and the high (La/Yb)N ratio values of metakomatiite and metadacite. The metakomatiite and the eastern and western metabasalts feature a vector from the MORB-OIB array to the volcanic arc array in the Nb/Yb-Th/Yb diagram, similar to the Archean intraoceanic arc-basin systems. The geochemical pattern of the eastern and western metabasalts in the Zr-Zr/Y diagram suggests volcanism in nearby island arc and back-arc basin settings, respectively. The 2595 ± 21 Ma U-Pb zircon crystallization age of the metadacite allowed the determination of the timing of volcanism in the MNGB. Therefore, an intraoceanic provenance in an arc-basin system is proposed for the MNGB in the Neoarchean, which was later compressed between cratonic blocks during the Rhyacian-Orosirian event.

Laughter is an omnipresent social phenomenon in the life of individuals and, in its various forms, it accompanies their interacting, or even better, it contributes to its orderly realization. Although it is so common, it is polyvalent, ambiguous and difficult to grasp. Therefore, in the article we will try to take some steps in the direction of delineating a socio-logic of laughter, regarded both as a phenomenon of order and as a mode of social action.

This article aims at describing the production of “races” as the result of categorization processes. During the social interactions of everyday life, in its different spheres, borders are linguistically and continuously realised and, in that way, value-related assumptions and moral pre-conceptions – on which discriminatory behaviours of different intensity are sometimes based – are imported. To examine the mechanisms of linguistic production of the border is exactly what will allow us to point out the need of knowing how to maintain ourselves able to abandon our categories, to think the “between” and to perform the crossing.

The article aims at showing how to produce, to use, or to look at images allow to make things in the world, with contextual meanings; that is, how the images perform, or are means for performing, different actions in specific situations. I will describe various examples of actions performed by and through images, while attempting to broaden the current definition of images or, at least, the idea we have of them. In that way, the relations between image and agency, and image and writing, will be considered, with the purpose of finally outlining some significant aspects of the action performed by means of “bodily images” (from gazes to gestures).

When we witness events as those occurred in Paris on 7-9 January 2015 and in Copenhagen on 14-15 February 2015 (mentioning two among the most striking cases in a list which could include many other similar events spread all over Europe and over the years), in which young second- or third-generation immigrants often turn out to be involved, we have the wish and need to attempt to identify, at least preliminarily, hypothetical, possible explanatory factors, whether facilitating or simply intervening. As this essay aims at illustrating, those factors have to do with both the cohesion of the European societies and what is happening on the international scene. The article will only deal with the first aspect, which sometimes, however, is connected with the Isis’s enticement. In the light of the identified interrelated elements, the essay ends with a short reflection on the freedom of expression, which has been more than symbolically challenged by the above mentioned attacks.

We describe the even Gorenstein liaison classes of ropes supported on a line which are not arithmetically Buchsbaum.

This essay sets out an approach to the study of those visual and verbal traces that, according to “common sense”, relate to individual identity. It will thus consider that identity as an image, locally constituted in the course of social interactions and open to description by the sociologist who – for example via videorecording – is able to capture not only its linguistic aspects but also, equally important, those related to its visible appearance.

La nota critica sullo sguardo delle scienze sociali verso l’Europa intende presentare i volumi di Sciolla, Beck e Grande, Passerini e Giddens nel contesto di un mutamento tanto delle società di volta in volta considerate parte del Vecchio Continente, quanto degli strumenti concettuali necessari a comprendere tali trasformazioni. Ripensare la nozione stessa di società, descrivere i cambiamenti transnazionali di quest’ultima, tentare di spiegare cosa sia e possa essere oggi l’Europa lungo dimensioni diverse, che vanno dalla discussione dei suoi aspetti identitari a quella del suo modello di coesione sociale, rappresentano alcune delle sfide più importanti poste dall’Europa ai suoi studiosi.

In the last decade, we have developed and validated an in silico concept based on multidimensional QSAR (mQSAR) for the prediction of the toxic potential of drugs and environmental chemicals. Presently, the VirtualToxLab includes eleven so-called virtual test kits for estrogen (?/?), androgen, thyroid (?/?), glucocorticoid, aryl hydrocarbon, mineralocorticoid and peroxisome proliferator-activated receptor ? as well as for the enzymes cytochrome P450 3A4 and 2A13. The surrogates have been tested against a total of 824 compounds and are able to predict the binding affinity close to the experimental uncertainty with only six of the 194 test compounds giving calculated results more than a factor of 10 off the experimental binding affinity and the maximal individual deviation not exceeding a factor of 15. These results suggest that our approach is suited for the in silico identification of endocrine-disrupting effects triggered by drugs and environmental chemicals. Most recently, the technology has been made available through the Internet for academic laboratories, hospitals and environmental organizations.
