Immigration et parcours d’intégration : scolarisation, formation professionnelle et travail des jeunes immigrés en Italie. Premières données sur une région du Nord.
No full textLe présent article se propose de vérifier comment l’immigration s’est déroulée en Emilia-Romagna, une Région du Nord de l’Italie, dans le contexte des modifications du phénomène en Italie.. Une attention particulière est dédiée au problème de l'intégration des jeunes immigrés.
Une première analyse étude l’évolution de l’immigration en Italie et en Emilia-Romagna, en utilisant les sources officielles : recensement et registres de population ; Ministère de l’Intérieur (motivations lors de la demande de permis de séjour); Ministère de l’Éducation (présence dans le système scolaire italien) ; données sur la participation au travail et sur les accidents de travail des étrangers.
Une deuxième analyse utilise les renseignements individuels des participants aux cours de formation professionnelle organisés par la Région Emilia-Romagna en 2001 financés avec de fonds publics.
L’attention est dirigée à la participation des jeunes à la scolarisation et à la formation professionnelle, qui sont importantes pour les processus d’intégration et de mobilité sociale.
On étude:
- les dynamiques d'enrôlement dans l'école et la réussite scolaire des jeunes avec citoyenneté pas italienne en comparaison avec les italiens;
- s’il y a des différences dans la participation à la formation professionnelle parmi italiens et étrangers
- s’il y a des différences parmi les extra-commuataires qui arrivent des pays d’Europe occidentale ou de l’Afrique du Nord, aussi dans l’optique de genre
Ab-initio study of oxygen vacancies in a-quartz
No full textExtrinsic levels, formation energies, and relaxation geometries are calculated ab initio for oxygen vacancies in a-quartz
SiO 2. The vacancy is found to be thermodynamically stable in the charge states Q = + 3, Q = 0, Q = - 2, and Q = - 3.
The charged states are stabilized by large and asymmetric distortions near the vacancy site. Concurrently, Franck-Condon
shifts for absorption and recombination related to these states are found to be strongly asymmetric. In undoped quartz, the
ground state of the vacancy is the neutral charge state, while for moderate p-type and n-type doping, the + 3 and - 3 states
are favored, respectively, over a wide Fermi level window. Optical transitions related to the vacancy are predicted at around
3 eV and 6.5 eV (absorption) and 2.5-3.0 eV (emission), depending on the charge state of the ground state
Educar/si a comportamenti smart
No full textIn una società in rapido cambiamento, segnata negli ultimi anni dalla pandemia da Covid-19, le difficoltà affrontate ci hanno anche permesso di riflettere e ripensare le nostre modalità lavorative, accelerando e trasformando repentinamente il processo che ha portato alla diffusione dello smart working o lavoro agile (pur se con forme e garanzie differenti). Ma quanto siamo preparati ed educati al lavoro agile? E quali azioni può mettere in campo un’organizzazione perché le/i lavoratrici/ori siano davvero smart? Il contributo affronta tali quesiti analizzando i dati relativi a occupazione femminile, competenze digitali e indicatori di performance digitale in Italia e in Europa per proporre alcune azioni utili a promuovere modalità di lavoro più flessibili, rispettose delle diversità, innovative, per poter davvero creare una comunità di lavoratrici e lavoratori coesi, solidali e consapevoli.In a rapidly changing society, marked in recent years by the Covid-19 pandemic, the difficulties faced have also allowed us to reflect and rethink our ways of working, accelerating and rapidly transforming the process that led to the spread of smart working (albeit with different forms and guarantees). But how prepared and educated are we for smart work? And what actions can an organization put in place so that the workers are really smart? The contribution addresses these questions by analyzing data relating to female employment, digital skills and digital performance indicators in Italy and in Europe to propose some useful actions to promote more flexible, diversity-friendly and innovative ways of working, in order to truly create a community of workers who are cohesive, supportive and responsible
Competenze professionali e stereotipi di genere
No full textIl concetto di competenze e di competenze professionali si è evoluto nel corso degli anni per includere, via via, livelli di complessità sempre maggiori, al di là del piano della prestazione che ne rappresenta un ele-mento imprescindibile, ma non esaustivo. Quando si pensa alle competenze relative alle professioni, si rischia di pensarle come un insieme svincolato dalle differenze identitarie e isola-to dalle influenze sociali e culturali dei contesti di riferimento. Al contrario, le competenze, che si compongono di un intreccio inestricabile di saperi specialistici e trasversali, possono incorporare i sistemi di aspettative che si attribuiscono ai ruoli maschili e femminili e non solo. Spencer e Spencer (1993) hanno utilizzato la me-tafora dell’iceberg per descrivere il complicato rapporto fra conoscenze e abilità, che ne rappresentano la parte emersa, e competenze trasversa-li, tacite, incluse le caratteristiche personali, che costituiscono il som-merso. La metafora dell’iceberg è calzante e suggestiva, poiché sottolinea, da un lato, la sproporzione fra le competenze lavorative manifeste e le componenti interne, legate al saper essere, oltre che alle dimensioni metacognitive; dall’altro perché evidenzia il carattere sommerso o na-scosto delle seconde, più difficili da rendere esplicite e valutabili. È proprio all’interno di questa ampia gamma di competenze trasversali strategiche e sommerse che si inseriscono i meccanismi più o meno impliciti che differenziano, nei ruoli professionali, aspettative e standard fra maschile e femminile e che determinano i noti meccanismi di segregazione nei ruoli e nelle carriere di donne e uomini
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
