I valori dell’amicizia e della collaborazione

Nella gioiosa celebrazione dell’ottantesimo compleanno del prof. Claudio Desinan mi è particolarmente gradito partecipare all’evento con il seguente contributo che dedico alla sua persona di pedagogista, testimone della memoria storica del gruppo triestino, sostenitore dei valori della famiglia, della persona e dell’educazione. Con esso intendo soprattutto esprimergli profonda gratitudine per la fedele amicizia con mio marito Duilio Gasparini, un sentimento questo che egli ha saputo diffondere sempre attorno a sé, verso colleghi e collaboratori. Inoltre mi propongo, nella seconda parte di questo scritto, di presentare una strategia pedagogica e didattica di consolidata esperienza, maturata poco per volta nella scuola dell’infanzia di Rimini, nella quale ho svolto attività di insegnante e di dirigente per lunghi anni. Si tratta di una strategia nata nella letteratura degli anni Settanta e perfezionata progressivamente nel tempo, che ha segnato profondamente la mia pratica educativa e che, a mio avviso, non ha perso il suo valore e può dire ancora qualcosa alle giovani generazioni di educatrici

The trajectory of student assistance in Brazilian higher education

O objetivo do presente artigo é problematizar a trajetória histórica dessa política no Brasil até a implementação do PNAES. A partir de pesquisa bibliográfica, será analisada a definição de assistência estudantil, situada entre a assistência social e a educação. Também será analisado seu reconhecimento enquanto direito social e política pública. Espera-se contribuir para a discussão, tendo em vista a escassez de estudos nessa temática.This article introduces the main results of the theoretical production study about student assistance; therefore, it characterizes itself as a state-of-the-art research. We understand that student assistance - as a public policy - is a process in construction, which requires continuity, perfectioning and qualification, so as to answer to the diversity of the student issues and to contribute effectively for higher education to be, indeed, everyone´s right

The role of topography and lateral velocity heterogeneities on near-source scattering and ground-motion variability

The scattering of seismic waves travelling in the Earth is not only caused by random velocity heterogeneity but also by surface topography. Both factors are known to strongly affect ground-motion complexity even at relatively short distance from the source. In this study, we simulate ground motion with a 3-D finite-difference wave propagation solver in the 0-5Hz frequency band using three topography models representative of the Swiss alpine region and realistic heterogeneous media characterized by the Von Karman correlation functions. Subsequently, we analyse and quantify the characteristics of the scattered wavefield in the near-source region. Our study shows that both topography and velocity heterogeneity scattering may excite large coda waves of comparable relative amplitude, especially at around 1Hz, although large variability in space may occur. Using the single scattering model, we estimate average QC values in the range 20-30 at 1Hz, 36-54 at 1.5Hz and 62-109 at 3Hz for constant background velocity models with no intrinsic attenuation. In principle, envelopes of topography-scattered seismic waves can be qualitatively predicted by theoretical back-scattering models, while forward- or hybrid-scattering models better reproduce the effects of random velocity heterogeneity on the wavefield. This is because continuous multiple scattering caused by small-scale velocity perturbations leads to more gentle coda decay and envelope broadening, while topography abruptly scatters the wavefield once it impinges the free surface. The large impedance contrast also results in more efficient mode mixing. However, the introduction of realistic low-velocity layers near the free surface increases the complexity of ground motion dramatically and indicates that the role of topography in elastic waves scattering can be relevant especially in proximity of the source. Long-period surface waves can form most of the late coda, especially when intrinsic attenuation is taken into account. Our simulations indicate that both topography and velocity heterogeneity scattering may result in large ground-motion variability, characterized by standard deviation values in the range 0.2-0.5 also at short distance from the source. We conclude that both topography and velocity heterogeneity should be considered to correctly assess the ground-motion variability in earthquake scenario studies even at intermediate frequenc

ICT, Creativity and Innovation: How to DesignEffective Project Teams

There are evidences, both from theoretical and managerial perspective, that team creativity is one of success factor for ICT innovative projects. This article focuses on the team design for ICT project, considering the relevance of the collective creative dimension. What is the relationship between individual and collective creativity? How to design and manage creative teams in ICT projects? We developed a wide research programme aiming at going deeper in creativity dynamics to understand what factors and which processes contribute to increase or reduce the creative performance at group level. According to our research aims and considering the review of the specific literature, we designed an experiment. Multiple measures of both individual and group creativity were considered. Results confirmed our main assumption: individual creativity is positively related with group creativity but it does not fully explain it. Moreover, individual creativity has different significant impacts on the three different collective creativity components. Finally, we suggest some practical guidelines for managing an effective creative ICT project team, to support the team members staffing and the group composition

Competition between Polar and Antiferrodistortive Modes and Correlated Dynamics of the Methylammonium Molecules in MAPbI3_3 from Anelastic and Dielectric Measurements

The mechanisms behind the exceptional photovoltaic properties of the metallorganic perovskites are still debated, and include a ferroelectric (FE) state from the ordering of the electric dipoles of the organic molecules. We present the first anelastic (complex Young's modulus) and new dielectric measurements on CH$_{3}$NH$_{3}$PbI$_3$, which provide new insight on the reorientation dynamics of the organic molecules, and the reason why they do not form a FE state. The permittivity is fitted within the tetragonal phase with an expression that includes the coupling between FE and octahedral tilt modes, indicating that the coupling is competitive and prevents FE ordering. The onset of the orthorhombic phase is accompanied by sharp stiffening, analogous to the drop of permittivity, due to the hindered molecular dynamics. On further cooling, an intense anelastic relaxation process without a dielectric counterpart suggests the reorientation of clusters of molecules with strong antiferroelectric correlations.Comment: accepted in J.

Broad-band near-field ground motion simulations in 3-dimensional scattering media

The heterogeneous nature of Earth's crust is manifested in the scattering of propagating seismic waves. In recent years, different techniques have been developed to include such phenomenon in broad-band ground-motion calculations, either considering scattering as a semi-stochastic or purely stochastic process. In this study, we simulate broad-band (0-10Hz) ground motions with a 3-D finite-difference wave propagation solver using several 3-D media characterized by von Karman correlation functions with different correlation lengths and standard deviation values. Our goal is to investigate scattering characteristics and its influence on the seismic wavefield at short and intermediate distances from the source in terms of ground motion parameters. We also examine scattering phenomena, related to the loss of radiation pattern and the directivity breakdown. We first simulate broad-band ground motions for a point-source characterized by a classic ω2 spectrum model. Fault finiteness is then introduced by means of a Haskell-type source model presenting both subshear and super-shear rupture speed. Results indicate that scattering plays an important role in ground motion even at short distances from the source, where source effects are thought to be dominating. In particular, peak ground motion parameters can be affected even at relatively low frequencies, implying that earthquake ground-motion simulations should include scattering also for peak ground velocity (PGV) calculations. At the same time, we find a gradual loss of the source signature in the 2-5Hz frequency range, together with a distortion of the Mach cones in case of super-shear rupture. For more complex source models and truly heterogeneous Earth, these effects may occur even at lower frequencies. Our simulations suggests that von Karman correlation functions with correlation length between several hundred metres and few kilometres, Hurst exponent around 0.3 and standard deviation in the 5-10percent range reproduce the available observation

Sensitivity of broad-band ground-motion simulations to earthquake source and Earth structure variations: an application to the Messina Straits (Italy)

In this paper, we investigate ground-motion variability due to different faulting approximations and crustal-model parametrizations in the Messina Straits area (Southern Italy). Considering three 1-D velocity models proposed for this region and a total of 72 different source realizations, we compute broad-band (0-10 Hz) synthetics for Mw 7.0 events using a fault plane geometry recently proposed. We explore source complexity in terms of classic kinematic (constant rise-time and rupture speed) and pseudo-dynamic models (variable rise-time and rupture speed). Heterogeneous slip distributions are generated using a Von Karman autocorrelation function. Rise-time variability is related to slip, whereas rupture speed variations are connected to static stress drop. Boxcar, triangle and modified Yoffe are the adopted source time functions. We find that ground-motion variability associated to differences in crustal models is constant and becomes important at intermediate and long periods. On the other hand, source-induced ground-motion variability is negligible at long periods and strong at intermediate-short periods. Using our source-modelling approach and the three different 1-D structural models, we investigate shaking levels for the 1908 Mw 7.1 Messina earthquake adopting a recently proposed model for fault geometry and final slip. Our simulations suggest that peak levels in Messina and Reggio Calabria must have reached 0.6-0.7 g during this earthquak

Harmony of transitions in assessing interpersonal motivations in transcripts analysis can discriminate between Adult Attachment Interview secure and disorganized individuals

SUMMARY. Aim. Assessing Interpersonal Motivations in Transcripts (AIMIT) is a validated coding system to assess the activation of interpersonal motivational systems (IMS) in the transcripts of psychotherapy sessions. The Transition Index (TI) is an AIMIT measure that reflects the levels of organisation, synchronisation and harmony amongst two or more IMS when they are rapidly shifting or simultaneously in the clinical dialogue. It is supposed to be a measure of integration and coherence of the patient’s state of mind within the psychotherapeutic sessions. It has also been hypothesized that low TI could be a marker for disorganization of attachment of the patient leading to difficulties in the therapeutic relationships and ruptures in the therapeutic alliance. In order to assess this hypothesis we tested its capability to discriminate between Adult Attachment Interview (AAI) organized and disorganized individuals. Methods. Two groups of 15 transcriptions of AAI matched for age and sex, one classified as free-autonomous and one as disorganized, were analysed by the AIMIT method. Results. Compared to organized individuals, disorganized patients at AAI reported lower TI scores (3.7±0.63 vs 3.0±0.53; F=2.98, p=0.005). Furthermore, TI showed a good discriminant capability (Wilks’ Lambda=0.77, p=0.004). Discussion and Conclusion. This result seems to confirm the usefulness and reliability of AIMIT analysis in evaluating the interpersonal difficulties which often characterize the therapeutic relationship with disorganized attachment patient
