Modelling Network Data through Partial Least Squares Methodology
The paper stems from the idea to draw a statistical soft-modeling framework to network data. Network data arise in very different and multidisciplinary fields (Sociology, Economics, Informatics, Communications, and so on), in order to study relational ties among units. The different fields highlighted in recent years the necessity to collect together relational and attribute data, as well as meta-data describing the actors in the network. Usual relational datasets are characterized by i) very different amount of units (from very few units to huge networks), ii) biased sampling (for instance snow-ball samplings are biased because they give people with more social connections a higher chance of selection, iii) heterogeneous
kind of information attached to both nodes and ties.
These facets highlights the difficulties, and sometime the impossibility, for classical statistical tools and models to be satisfactory applied.
From a different point of view, many theoretical behavioral models, often assumed in social network analysis, are far from being directly observable. It still remains the possibility of measuring them as latent factors depending from multidimensional constructs. In these frameworks, we propose a component-based approach to network data through Partial Least Squares algorithms
BREVE STORIA DELLA CLASSE DI CONCORSO A23 - LINGUA ITALIANA PER DISCENTI DI LINGUA STRANIERA
Nel corso degli ultimi trent’anni la crescente presenza di studentesse e studenti neoarrivati, immigrati e figli di genitori immigrati ha fortemente influenzato la società italiana e ha impegnato il sistema scolastico al fine di favorire la loro integrazione linguistica e sociale.
Nonostante nel corso degli ultimi decenni il numero delle studentesse e degli studenti alloglotti sia aumentato sensibilmente, solo a partire dall’anno scolastico 2017/2018 è stata introdotta la figura del docente di Lingua italiana per discenti di lingua straniera. L’assenza di docenti esperti e competenti nell’ambito della didattica dell’italiano L2, infatti, ha a lungo caratterizzato gli interventi di integrazione linguistica rivolti agli studenti alloglotti. Per questo motivo l’istituzionalizzazione della classe di concorso A23-Lingua italiana per discenti di lingua straniera è un momento fondamentale per il riconoscimento istituzionale dell’insegnamento dell’italiano L2 nella scuola pubblica. Il presente contributo si propone di ripercorrere le diverse tappe che hanno portato al primo inserimento dei docenti della classe di concorso A23 e mette in luce i problemi e le criticità emerse durante i primi tre anni scolastici di servizio.
A short history of the competition class A23 - Italian language for foreign language learners
Over the last thirty years, the arrival of a large number of foreign people has had a considerable impact on Italian society. Consequently, the national school system has been greatly affected, seen in daily life at Italian schools. Since the 2017/2018 school year, for the first time, teachers who had successfully completed a structured course on teaching Italian as a second language were included in Italian public school staff. For a long time, Italian public schools did not have highly qualified staff able to face problems linked to learning Italian as a second language. For this reason, the recruitment of A23 teachers can be considered key. This paper focuses on the major steps that led to the inclusion of professionals qualified to teach Lingua italiana per discenti di lingua straniera. in Italian public schools
Second language learning for vulnerable adult migrants: The case of the Italian public school
Over the last years, thousands of asylum seekers and refugees have arrived in Italy, including a large number of teenagers without any adult caregivers and women. A significant part of them is placed in the Italian language courses for foreigners organised by the Provincial Centre for Adult Education, commonly called CPIA (Centro Provinciale per l’Istruzione degli Adulti). This paper addresses the exploration of the language testing and assessment of the courses organized by this institution. With the aim of evaluating these aspects, the paper concentrates on the CPIA, its teachers, and its students. Focusing on CPIA’s language courses, we investigate the language testing and assessment carried out at the beginning and at the end of the language courses. Thanks to these observations, the paper tries to identify some critical aspects and to understand their causes
MALT-IT2: A New Resource to Measure Text Difficulty in light of CEFR levels for Italian L2 learning
Patterns of modality and functional equivalence in the language of contracts: A corpus-based, intra-/interlinguistic, intercultural study for translation professionals and educators
This comparative study aims to make a three-fold contribution to the analysis of the language of contracts in Italian and English. It will first illustrate how deonticity is conveyed by highlighting patterns of modality in contract texts and providing a comparative analysis of linguistic variation across cultures. It will then investigate collocations that constitute cross-cultural challenges in order to identify relations binding their conceptual, intercultural legal features so as to find appropriate functional equivalents in the target language and culture. Finally, it will illustrate problem-solving strategies for professional and educational purposes, and prove how translators can achieve epistemic fluency, growth in conceptual content, and competent communicative action
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
