Invenzione di un linguaggio tramite interazione in una scuola primaria
In questo lavoro viene presentata parte di una ricerca1, che analizza il rapporto tra linguaggio e sviluppo di abilità logiche in bambini di scuola primaria in particolari situazioni di interazione. Le abilità logiche, in questa ricerca, vengono intese come la capacità di individuare e scegliere differenti strategie per risolvere problemi riguardanti compiti logici (Coppola, Mollo, Pacelli, 2009). Le attività proposte ai bambini riguardano aspetti assertivi e procedurali del linguaggio, entrambi fondamentali nel funzionamento e nello sviluppo del pensiero matematico (Gerla, 1988). In particolare in questo lavoro vengono discussi i risultati relativi alla costruzione da parte dei bambini, all'interno di una data situazione, di semplici linguaggi procedurali per la soluzione di un problema. Il background teorico di riferimento è costituito da un lato dalla logica formale, dall’altro lato dai contributi della scuola storico culturale (Vygotskij, 1934) e dal costruzionismo sociale genetico (Perret-Clermont, 1979; Iannaccone, 2010)

The effect of microstructure on the tensile and impact behaviour of short-glass fibre-reinforced polyamide 6.6 as assessed by micro-computed tomography
Injection moulding of short-fibre-reinforced thermoplastics opens a new dimension in the field of mass production of complicated net-shaped parts with accurate dimensions and the new challenge is to produce parts with tailored properties. However, the layered structure frequently observed in these composites strongly affects their mechanical behaviour and constitutes the main difficulty in transferring the results of tests performed on standard specimens to actual components and parts. In addition, to use injection-moulded composite materials safely, their mechanical behaviour under different loading conditions must be well understood. In the present work, the effect of microstructure, in terms of fibre length and orientation, on the tensile and impact behaviour of injection-moulded short-glass fibre-reinforced polyamide 6.6 was investigated. Digital reconstruction of the three-dimensional structure of samples, differently oriented with respect to the melt flow path, was obtained by the high-spatial-resolution non-destructive technique of synchrotron radiation micro-computed tomography (micro-CT). Automatic evaluation of the fibre length distribution was developed by a global method based on the mean fibre length distribution, computed from the star length distribution (SLD). The results of uniaxial tensile tests and Izod impact experiments were successfully correlated with morphological analysis of fractured surfaces and the results of SLD. These studies revealed important changes in fibre orientation distribution when the sample orientation is changed with respect to melt flow direction, which also strongly influenced the composite mechanical response.Fil: Rosic, N..

Epidermal cell junctions and their regulation by p63 in health and disease
As the outermost tissue of the body, the epidermis is the first physical barrier for any pressure, stress or trauma. Several specialized cell–matrix and cell–cell adhesion structures, together with an intracellular network of dedicated intermediate filaments, are required to confer critical resilience to mechanical stress. The transcription factor p63 is a master regulator of gene expression in the epidermis and in other stratified epithelia. It has been extensively demonstrated that p63 positively controls a large number of tissue-specific genes, including those encoding a large fraction of tissue-restricted cell adhesion molecules. Consistent with p63 functions in cell adhesion and in epidermal differentiation, heterozygous mutations clustered mainly in the p63 C-terminus are causative of AEC syndrome, an autosomal dominant disorder characterized by cleft palate, ankyloblepharon and ectodermal dysplasia associated with severe skin erosions, bleeding and infections. The molecular basis of skin erosions in AEC patients is not fully understood, although defects in desmosomes and in other cell junctions are likely to be involved. Here, we provide an extensive review of the different epidermal cell junctions that cooperate to withstand mechanical stress and on the mechanisms by which p63 regulates gene expression of their components in healthy skin and in AEC syndrome. Collectively, advancement in understanding the molecular mechanisms by which epidermal cell junctions precisely exert their functions and how p63 orchestrates their coordinated expression, will ultimately lead to insight into developing future strategies for the treatment of AEC syndrome and more in generally for diseases that share an overlapping phenotype
