Tutelare il lavoro dei migranti in agricoltura come "pratica di diritto ribelle"
No full textA partire dall’esperienza dei lavoratori migranti vittime di sfruttamento lavorativo, le loro percezioni sulle cause del fenomeno e le loro aspettative, il presente contributo ricostruisce il quadro dei profili di violazione delle tutele lavoro alle quali questi lavoratori sono soggetti. L’obiettivo è riflettere criticamente sulle risposte istituzionali messe in atto e immaginare alla luce dell’approccio della legal mobilisation – un termine che descrive i processi attraverso i quali gli attori, individuali o collettivi, usano il diritto come strumento per promuovere le loro rivendicazioni nei confronti di altri individui o della società – diverse e più efficaci strategie legali di intervento
Stiff and tough hydrophobic cellulose-silica aerogels from bacterial cellulose and fumed silica
No full textThis work reports hydrophobic and compressible cellulose- silica composite aerogels prepared by freeze drying fumed silica (FS) infiltrated bacterial cellulose (BC) hydrogels. Compression modulus of cellulose silica (BC-FS) aerogels increase from 0.22 MPa up to 3.83 MPa with respect to pure freeze dried BC. BC with 8% silica (BC-FS-8) aerogel demonstrated excellent robustness and is compressible with full elastic recovery for 50 cycles without any substantial drop in mechanical strength. All aerogels exhibit more than 96 % porosity, specific surface up to 420 m2/g, density ranging from 0.01 to 0.04 g/cm3 and thermal conductivity less than 0.04 W/mK. Hydrophobic aerogels demonstrated excellent oil absorption properties from oil/water mixture, with an oil uptake up to 28 times of its original weight. The cyclic test conducted for oil absorption shows that the aerogel can be used at least 10 times for oil recovery without any substantial reduction in the uptake capacity
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
