p-grupos finitos
1997
In the first part, new bounds for the number of conjugacy classes of maximal length of a finite $p$-group $G$, $r(G)$, are obtained, and they are related with the length of these classes. If $r(G)=p^m-b-1$, there exists a unique normal subgroup of order $p^b$, $N_b$, which is characteristic, and structural properties of these groups are studied when $b\le 3$, by paying special attention to the relation between $N_b$, $Z(G)$ and $G$. In the second part, new bounds for the degree of commutativity of a $p$-group of maximal class are established. In Chapter 2, the bounds known for $c$ are reviewed. In Chapter 3, the reuslts obtained by Shepherd for $c_0\le 4$ are extended to $c_0\le 10$ by mean…
Thermo-hygrometric comfort in the lecture hall of a library: methodology and experimental evidence.
2012
The present study verifies the thermo hygrometric comfort conditions in subjects of a university library users, evaluating the differences and peculiarities in the data collected at the measurement campaign. Particularities of the investigation is the period studied concerning the time frame of the Middle season, which is not expected to power the air conditioning systems. Based on assumptions on the thermal resistance of clothing in the spring and the metabolic type of subjects, the environmental parameters were monitored in some work position in the reading hall in the library of the Faculty of Medicine and Surgery of the University of Palermo. The article presents analyses of the measure…
Online Civic Identity. Extraction of Features
2013
Abstract The paper presents the importance of study the reactions of the readers and writers of online journals forums from the civic identity point of view, in order to put in evidence categories of publics in the benefit of media, persons and groups. The method is intended to help journalists, PR specialists who are motivated to understand their publics and to target them in a more precise way, in order to upgrade the impact of their online discourse on the people in the community, to know how deep the civic involvement of the people is to the problems of the community.

Conditions et enjeux pédagogiques de la constitution de classes à cours multiples dans les écoles primaires
2006
06022; La problématique de cette recherche s'inscrit dans le schéma global suivant, qui se donne pour objectif d'analyser successivement les pratiques de constitution des classes (nombre et nature des classes au sein des écoles), les modalités d'affectation des élèves et des enseignants dans ces classes et enfin l'efficacité pédagogique des différents types de groupement réalisés.
Dynamiques de classe et efficacité scolaire
2003
The present research aims at describing the efficiency of teaching practices involved in dynamic "teaching-training" processes. Our main approach consisted in relating in-class-monitoring to the results of knowledge-acquisition by pupils so as to better explain through what means the pupils’ knowledge and competence are acquired. At a theoretical level this implies combining the "process-product" paradigm along with the "ecological" paradigm [ 1]. Results obtained indicate that bringing together the analysis of teaching practices with the evaluation of their impact "which are still limited to an exploratory stage" are a method well-worth pursuing. [ 1] See above the general introduction to …
PROCESSI DI TRADUZIONE E SCRITTURA ELEMENTARE NELLA LINGUA STRANIERA TEDESCA
2014
L’articolo presenta i primi risultati di una ricerca qualitativa sulla scrittura in lingua straniera con l’aiuto di Google Traduttore. In questo lavoro prendiamo in esame i processi, cioè le forme di costruzione delle strutture verbali e discorsive nel mentre si articolano dal vivo durante la costruzione di una traduzione di sito web di carattere turistico. Lo studio si è svolto nell’anno accademico 2013/2014 e si è basato sulla videoregistrazione di circa 12 ore di lavoro in gruppi di 4 persone mentre progettano, lavorano e producono la stesura di parti della homepage in lingua tedesca di un sito turistico. Il lavoro mette in risalto sia le potenzialità che i limiti dell’utilizzo delle ris…
Analyse des procédures d'orientation au palier de troisième
1983
Texte de la communication présentée au colloque sur « Les inégalités dans l'Enseignement secondaire» (IREDU, Dijon, 27-28 mai 1982).; International audience; Outre la présentation d'un modèle théorique de l'orientation (fondé sur des arbitrages entre l'intérêt que présentent les études et le risque d'y échouer) et le rappel des principales différenciations (sociales, scolaires, par âge ...) opérées à l'entrée dans le second cycle, l'essentiel du texte porte sur l'analyse du fonctionnement de la commission d'orientation. On y examine en premier lieu comment la procédure dans son ensemble prend en compte de façon simultanée toutes les caractéristiques "scolaires" de l'élève et la pondération …
Bioassays to monitor taspase1 function for the identification of pharmacogenetic inhibitors
2011
Background Threonine Aspartase 1 (Taspase1) mediates cleavage of the mixed lineage leukemia (MLL) protein and leukemia provoking MLL-fusions. In contrast to other proteases, the understanding of Taspase1's (patho)biological relevance and function is limited, since neither small molecule inhibitors nor cell based functional assays for Taspase1 are currently available. Methodology/Findings Efficient cell-based assays to probe Taspase1 function in vivo are presented here. These are composed of glutathione S-transferase, autofluorescent protein variants, Taspase1 cleavage sites and rational combinations of nuclear import and export signals. The biosensors localize predominantly to the cytoplasm…
Chern classes of the moduli stack of curves
2005
Here we calculate the Chern classes of ${\bar {\mathcal M}}_{g,n}$, the moduli stack of stable n-pointed curves. In particular, we prove that such classes lie in the tautological ring.
