Da richiedenti asilo a lavoratori essenziali. Pandemia e cambiamenti della composizione della forza lavoro immigrata nell’agricoltura trentina
Full text linkIl contributo indaga le trasformazioni in atto rispetto al reclutamento, alla
composizione e all’organizzazione della forza lavoro immigrata nell’agri-
coltura trentina. La coltivazione frutticola costituisce una delle attività
economiche più importanti del Trentino e si basa strutturalmente sul
lavoro immigrato, soprattutto di stagionali ‘comunitari’ dall’Est Europa.
Il loro reclutamento si è basato su un modello consolidato che prevede
il rapporto fiduciario tra datori di lavoro e lavoratori. Tale modello ha
iniziato a entrare in crisi per effetto del ri-disegnamento delle traiettorie
migratorie dei lavoratori che si stanno orientando verso Paesi dell’Eu-
ropa centrale. Ecco che, quindi, si è iniziato a fare ricorso a rifugiati e
richiedenti asilo, arrivati in Trentino negli ultimi anni. Tale processo ha
subito una forte accelerazione per effetto della pandemi
The evolution of the therapeutic strategy in hepatitis C: Features of sofosbuvir and indications.
No full textAbstractThe treatment of chronic hepatitis C virus infection is rapidly evolving with the entry into the therapeutic armamentarium of a series of new and highly effective direct antiviral agents, targeted to the different virus structures involved in hepatitis C virus replication and assembly. Sofosbuvir is considered, without controversies, the most promising single direct antiviral agent in the current scenario. The pharmacological properties of sofosbuvir allow a single oral daily administration and ensure a favourable drug–drug interaction profile, compared to other direct antiviral agents. Clinical development of sofosbuvir has been conducted with the strategy of positioning it as the backbone drug of several combination regimes, including triple therapy with pegylated interferon and ribavirin, but also IFN-free regimen with ribavirin alone as well as with complementary direct antiviral agents directed against other virus targets. Based on available data and International guidelines sofosbuvir is indicated in combination with pegylated interferon and ribavirin in patients infected with hepatitis C virus 1 to 6 that can take interferon, and this regimen is particularly efficacious in those who have not received any previous antiviral treatment. The pangenotypic activity, excellent safety (even in advanced liver disease) make sofosbuvir the ideal backbone for combination therapy in all hepatitis C virus patients subgroups, the limiting factors being safety and tolerability of the combined direct antiviral agent rather than those of sofosbuvir itself
The globalisation of Italian agriculture. Transformations of migrant labour composition in agriculture in Trentino
Full text linkThe cultivation of apples is one of the principal eco-
nomic activities in Trentino, which is responsible for
25% of Italian apple production and 4% of European
apple production. The industry is structurally based on
migrant work, especially from Eastern European coun-
tries in the EU. This model has come up against obstacles
due to EU migrant workers redrawing their trajecto-
ries: They now tend to remain in their country of origin
or move towards central European countries, where
they find better wages and working conditions. This is
also due to the inadequacy of Italian migration poli-
cies, which make it difficult for employers to recruit
migrant workers. As a result, employers started to recruit
refugees and asylum seekers from countries in the sub-
Saharan and Indian subcontinent who had recently
arrived in Trentino. This article analyses these trans-
formations and the trend of ‘refugeeisation’ process of
the agricultural workforce, as well as the partial replace-
ment of seasonal workers in Trentino. It then focuses on
the impact of the pandemic on international recruitment
and on the organisation of the migrant workforce
Un modello trentino di ‘rifugizzazione’? Meccanismi di reclutamento e composizione della forza lavoro immigrata nell’agricoltura del Trentino
Full text linkThe paper investigates the transformations of the agricultural labor market in
Trentino and the changes in the forms of recruitment and organization of the
migrant workforce and its composition. Fruit cultivation, especially apples, is one
of the most important economic activities in Trentino and is structurally based on
migrant work, especially from eastern EU countries. The recruitment of workers
was based on the relationship of trust between employers and seasonal workers.
This model begun to jam due to the redesign of the trajectories of EU migrant
workers, who are moving towards central European countries. Thus, employers
started to recruit refugees and asylum seekers, arrived in Trentino in recent years.
In addition to these transformations, the paper analyzes the impact of the pandemic
on international recruitment mechanisms and the organization of the migrant workforce
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
