To assess the peri-implant soft tissue profiles between argon plasma treatment (PT) and non-treated (NPT) healing abutments by comparing clinical and histological parameters 2 months following abutment placement.
MATERIALS AND METHODS
Thirty participants were randomly assigned to argon-plasma treatment abutments group (PT) or non-treated abutments (NPT) group. Two months after healing abutment placement, soft peri-implant tissues and abutment were harvested, and histological and clinical parameters including plaque index, bleeding on probing, and keratinized mucosa diameter (KM) were assessed. Specialized stainings (hematoxylin-eosin and picrocirious red) coupled with immunohistochemistry (vimentin, collagen, and CK10) were performed to assess soft tissue inflammation and healing, and the collagen content keratinization. In addition to standard statistical methods, machine learning algorithms were applied for advanced soft tissue profiling between the test and control groups.
RESULTS
PT group showed lower plaque accumulation and inflammation grade (6.71% vs. 13.25%, respectively; p-value 0.02), and more advanced connective tissue healing and integration compared to NPT (31.77% vs. 23.3%, respectively; p = 0.009). In the control group, more expressed keratinization was found compared to the PT group, showing significantly higher CK10 (>47.5%). No differences in KM were found between the groups.
SIGNIFICANCE
PT seems to be a promising protocol for guided peri-implant soft tissue morphogenesis reducing plaque accumulation and inflammation, and stimulating collagen and soft tissue but without effects on epithelial tissues and keratinization

Né qui, né altrove : migration, detention, desertion : a dialogue
No full textSandro Mezzadra teaches the History of Contemporary Political Thought at the University of Bologna. He is an active figure in the alternative globalisation movement in Italy, and has been particularly involved in bringing the question of migration to the centre of political struggle in that movement. Sandro is the author of works such as Diritto di fuga: Migrazioni, cittadinanza, globalizzazione (2001) and (with Fabio Raimondi) Oltre Genova, oltre New York: Tesi sul movimento globale (2001). He is also a member of the editorial collective of DeriveApprodi magazine, one of the chief venues in Italy for the critical analysis of contemporary capitalism. We met in Bologna one foggy January afternoon to discuss the global movement, migration, and border control in Europe and Australia
The part-time work and job on call in JustEatTakeaway supplementary company agreement for Takeaway.com Express Italy (Just Eat group) riders
No full textThe comment deals with the part-time work regulation, contained, in particular, in Part II of the JustEatTakeaway supplementary company
agreement. The use of this instrument is expected to be massive, considering that it is, in the parties' plans, the common form of work in the company.
The author analyses the provisions contained in the collective agreement, especially in the light of the discipline contained in the CCNL Logistica, Trasporto, Merci e Spedizione and in the Protocol signed on 18 July 2018 for the same sector. The author also discusses the rules on overtime and supplementary work and the rules on intermittent work, which are also subject to specific contractual regulations
Bridging the Boundaries of Science and Technology: Author-Inventors and Quality of Inventions
No full textA growing body of research examines the relationship between science and technology by using a social network lens to look at the collaboration networks between authors and inventors. Building on this research, we study how publishing inventors’ (author-inventors’) structural position in scientific (co-authorship) and technological (co-invention) networks affects the quality of their inventions. We probe author-inventors’ characteristics by identifying those who act as cutpoints—i.e., those who play a pivotal role in holding the two networks together. Cutpoints can be connected to more or less cohesive subgroups of the scientific network and hence have access to more or less diverse knowledge bases. The results of the analysis suggest that author-inventors’ structural position—in particular, whether they are cutpoints and belong to more cohesive subgroups of the scientific network—is highly consequential for the quality of the inventions with which they are involved. We tested our hypotheses in the emerging field of nanotechnology. The theoretical and managerial implications of the results are discussed

The working time regulation in JustEatTakeaway supplementary company agreement for Takeaway.com Express Italy (Just Eat group) riders
No full textConsidering that the regulation of the time and the possible economic relevance of the phases of waiting for delivery is a field of discussion still access regarding the work of riders, the Author analyzes, in detail, how the JustEatTakeway supplementary company agreement regulates
the working hours of riders. The Author illustrates the discipline contained in the CCNL Logistica,Trasporto, Merci e Spedizione and in the Protocol signed on July 18, 2018 for the same sector, to which the same company agreement in comment refers
The Topicality of Prehistory. A New Reading of Marx’s Analysis of “So-called Primitive Accumulation”
No full textThe essay discusses Marx’s analysis of ‘‘so-called primitive accumulation’’ starting from the idea that contemporary global capitalism is characterized by new enclosures and by a set of other processes long considered characteristic of the historical transition to capitalism. A reflection on this temporal short circuit leads the author to an investigation of some of the peculiarities and difficulties of Marx’s method as, for instance, the relationship between the historical and the logical order of exposition. Reading the temporal structures of capitalism against the backdrop of Marx’s analysis of primitive accumulation suggests an emphasis on temporal heterogeneity, on the intertwining of continuity and rupture, of progress and catastrophe, that is far from any ‘‘historicist’’ interpretation of Marx. From this point of view, the author investigates some of the key questions connected to primitive accumulation: the production of labor power as a commodity as a specific and strategic form of the production of subjectivity, the concept of transition, the role of violence in capitalist development, and the relationship between formal and real subsumption of labor under capital
