Women, Workers, Immigrants: Situated Representations of Trade Union Mobilizations in Italy within the Logistics Sector
Full text linkIn recent years, logistics workers (who are mostly immigrants) have engaged in various importantlabour mobilizations. Although it is a male dominated sector, women workers, when present, have played anincredibly active role. This was the case in the mobilizations in Bologna’s interport at the sorting, packaging andshipping warehouses of Yoox Net-A-Porter, a luxury e-commerce giant in the fashion industry, and at Italpizza’sproduction plant for the rolling out and topping of frozen pizzas, near Modena, both in Italy.This article will report on a qualitative research aimed at analyzing the working conditions of the immigrantwomen who took part in the mobilisations and recording their representations of the repercussions andimplications that these struggles had on their lives and on the socio-territorial contexts in which they took place.The research revealed that these labour conflicts involving immigrant women extended beyond the workplace,actively involving various groups within their socio-territorial context (associations, collectives, social centers,etc.), encompassing diverse struggles and going beyond purely union-related demands. Furthermore, thesecollective and self-organized experiences generated spaces for mutual care, the recognition of their agency, andpersonal and collective empowerment with broad transformative potential. In doing so, they created a sort of"community of struggle," a consequence of the action of "Indie Unions" and the emergence of "Communit
I riusi produttivi e abitativi di una mansio nella Toscana centromeridionale: lo scavo di Santa Cristina in Caio (Buonconvento – SI)
No full textThis paper deals with the fifth century residential and productive phases of the Santa Cristina in Caio, a Roman settlement functional at the cursus publicus (mansio) where between I and II centuries there ceramic production activities; the excavation revealed significant amounts of Mediterranean amphorae, dated between I and V centuries. Above the ruins of the Roman baths were built some houses in mixed technique, which reuses walls and roman building materials. On the the nearby hill of Poggio alle Fonti, we found another structure in mixed technique, probably a workshop of a blacksmith dating to the 5th century; this evidence testifies the continuation of production and commercial activities. The settlement of 5th century represents a transition between the phases of the Roman site, linked to an exchange economy and the early medieval period, based instead on agriculture and farming
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
Foliar deposition of electrostatic charged spray applied by a cannon sprayer on high tunnel strawberry
No full textStrawberry is the main soft fruit production in high tunnel cultivation of Trentino. With about 4000 t of yield per year, the regional strawberry production has increased in the last years and it represents almost the 70% in terms of quantity and about 60% in terms of value in the production sector of small fruits. To improve pesticides application efficiency is a difficult process because it can be affected by several factors some of which do not allow an easy and sufficient control. The cannon sprayer is one of the equipment widely in use for protected cultivations in this area. This type
of sprayer can be equipped with electrostatic charge devices, but the experience in how much this can improve the canopy deposition of PPP is not much. To acquire some preliminary data on the improvements achievable by the electrostatic
charged application technique an experiment was carried out in strawberry tunnels using a cannon sprayer (Tifone Bravo 600) equipped with an electrostatic device which was turned on in a first plot and off in a second one during spraying a tracer solution (yellow Tartrazine). The experimental tunnels were about 18 m long and they were sprayed from both the front openings of the structure travelling at a working speed of 1.2 km h-1. Plants were grown into bowl at the top of hanging trellises disposed into four rows for each tunnel and the canopy
stage was typical of the first decade of July (end of harvest). The applied volume was 1500 l ha-1 as usual in the area for this development stage. After drying of vegetation foliage was sampled at three different distances from the front of
tunnels (2-3 m, 6-7 m, 9-10 m) and at two depth levels of the canopy (external crown and internal foliage) in the two central rows of the protection structure. Sample analysis showed that the use of the electrostatic charge seems to increase the tracer deposit in the outer part of the vegetation, close to the opening of the tunnel. This effect seems have an influence also on the deposits of the inner leaves closer to the front of the tunnel, reducing them. In the inner part of the vegetation – the most difficult to cover – it seems to be no appreciable increase in deposition using the electrostatic charge. In the central
part of the tunnel, the effect was no more appreciable too. Further investigations appear suitable to determine the effect of this technique on earliest and more representative development stages of strawberry plant
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
