Il contributo focalizza l’attenzione sulle prime esperienze milanesi delle esposizioni d’arte e industria mettendo in rilievo quella del 1872 integrata con una Esposizione d’arte antica, quella del 1874 incentrata su una grande raccolta di arti applicate (Esposizione storica d’arte industriale) e, soprattutto, quella del 1895 (Esposizione eucaristica) precipuamente pensate per i cimeli d’arte sacra della Lombardia.

This paper considers some of the poems written by the English soldier-poet Isaac Rosenberg during the First World War in order to show his ecological awareness in the depiction of and reflection upon the devastating effects of warfare on the environment and on the man-nature relationship. By adopting an ecocritical perspective, his works will be studied in relation to con¬cepts of space and place, the peculiar features of the war zone, and the elaboration of the pastoral tradition. In conclusion, it will be suggested that the destruction of nature serves as a metaphor for the physical and psychological suffering of men.

To investigate competence in the social sciences, we propose to define competence as a particular configuration of the learner’s cognition, strategic repertoire, motivation, and orientation toward knowing. Specifically, we focus on epistemic beliefs and on the changes that a view of knowing as a complex, effortful, generative, evidence-seeking, and reflective enterprise entails. In this context, we discuss how familiarity with the processes used to justify knowledge claims within specific disciplinary communities can provide useful tools to develop the kind of adaptive and consistent thinking that characterize competence in different domains and how this focus may aid the identification of characteristics common across domains. We use our empirical exploration of adolescents’ development of competence in the domain of history to illustrate the implications of this theoretical framework, to highlight the relations between domain-specific epistemic beliefs and kind of understanding that students built as a result of reading multiple texts, and to suggest what pedagogical practices may have influenced students’ orientations toward knowing in these three history classes.

Let X be a smooth projective variety over an algebraically closed field k. We associate to X , in a functorial way, a multigraded k-algebra G(X), called the global ring of X . We find some results when dim X = 2, and we explicitly determine the global ring in two particular cases.

We study relationships between Hilbert functions and graded Betti numbers of two space curves C and C_0 bilinked by a sequence of basic double linkages; precisely we obtain bounds for the graded Betti numbers of C by means of the Hilbert functions of the two curves and the graded Betti numbers of C_0 . On the other hand for every set of integers satisfying these bounds we can construct a curve with these integers as its graded Betti numbers. As a consequence we get a Dubreil-type theorem for a curve C which strongly dominates C_0 at height h which is exactly the Amasaki bound for Buchsbaum curves. Moreover we deduce for biliaison classes of Buchsbaum curves that a strong Lazarsfeld-Rao property holds.

The possible degrees for the generators of an irreducible arithmetically Cohen Macaulay curve of P3 are computed in terms of its Hilbert function. For any set of admissible degrees a smooth curve of this type, generated in those degrees is constructed.
