Le origini delle trasformazioni birazionali: le trasformazioni quadratiche nella corrispondenza di Luigi Cremona
2012
Lo scopo di questa comunicazione è quello di tracciare, facendo uso anche della corrispondenza con Hirst, la storia delle trasformazioni quadratiche vista da Cremona, partendo dai lavori di Magnus e Steiner fino all’influenza che ebbe in lui la Memoria sulla trasformazione geometrica delle figure di Giovanni Virginio Schiaparelli.

I poligoni stellati: origini storiche ed implicazioni didattiche
2019
The genesis of mathematical concepts in the evolutionary line of human thought in the long story and the genesis in individual optics possess evident analogies. Starting from this assumption, we describe an activity presented to 15-year-old students; the aim was to consolidate fundamental concepts of Euclidean geometry related to regular polygons. The experimentation has used a didactic approach based on the historical evolution of the formal definition of regular star polygon through the centuries. The activity and the results obtained in terms of internalization of the concepts in the students are showed.

The Role of Leadership in Complex Strategic Networks: Enabling Effect Versus Emergence
2013
In today's knowledge-based economy, the sources of competitive advantage lie more and more in webs of interactions among a variety of actors (such as firms, universities, research organizations, government institutions and so on), that over time originate the emergence of strategic networks. The paper aims to shed light on the determinants of network interaction and the ensuing processes of knowledge and resource transfer and circulation, on which the networkbased sources of competitive advantage are rooted. Accordingly, by means of the adoption of the complexity system perspective, on the one hand, we underscore the emergent nature of network interactions stemming from the self-organizing …

Investigating the Structural Properties of an IT-Enabled Resource
2019
The synergistic combination and integration of information technology (IT) and other complementary organizational resources to form IT-enabled resources, has long been identified as one means through which organizations can derive benefits from IT. However, research shows that the integration required to form IT-enabled resources from which organizations derive benefits, also constrains the renewal and redeployment of the IT-enabled resources to address new strategic imperatives. Thus, there are several calls for further research on how organizations can sustain the derivation of benefits from IT especially in dynamic environments. This study responds to such calls. Specifically, it draws o…
Apprendimento, memoria, oblio
2012
Le teorie sulla memoria tengono conto sia della struttura della memoria che dei processi operanti al suo interno. Con il termine struttura ci si riferisce al modo in cui è organizzata la memoria, mentre con il termine processi si fa riferimento alle attività che si verificano all'interno della memoria. Apprendimento e memoria implicano una serie di stadi distinti. Il primo stadio noto come codifica, si riferisce a tutti quei fenomeni che hanno luogo durante la presentazione dell'informazione da ricordare. Il secondo stadio riguarda l'immagazzinamento delle informazioni come conseguenza del processo di codifica. Il terzo e ultimo stadio è il recupero delle informazioni immagazzinate.
Rola i zadania szkolnego doradcy zawodowego w planowaniu ścieżki kształcenia ucznia
2016
Wybór zawodu to bardzo istotna decyzja, przed podjęciem której staje każdy młody człowiek. Ma ona istotny wpływ na dalsze życie (zawodowe i poniekąd osobiste) każdego człowieka. Dlatego w trakcie edukacji uczeń może skorzystać z pomocy specjalistów z zakresu orientacji i poradnictwa zawodowego. W artykule omówione zostały podstawy prawne funkcjonowania doradztwa zawodowego w polskich placówkach oświatowych. Ponadto przedstawione zostały wymagania formalne, zakres obowiązków i cechy charakteru, jakimi musi legitymować się szkolny doradca zawodowy.
The Radó–Kneser–Choquet theorem for $p$-harmonic mappings between Riemannian surfaces
2020
In the planar setting the Rad\'o-Kneser-Choquet theorem states that a harmonic map from the unit disk onto a Jordan domain bounded by a convex curve is a diffeomorphism provided that the boundary mapping is a homeomorphism. We prove the injectivity criterion of Rad\'o-Kneser-Choquet for $p$-harmonic mappings between Riemannian surfaces. In our proof of the injecticity criterion we approximate the $p$-harmonic map with auxiliary mappings that solve uniformly elliptic systems. We prove that each auxiliary mapping has a positive Jacobian by a homotopy argument. We keep the maps injective all the way through the homotopy with the help of the minimum principle for a certain subharmonic expressio…
