Trade and Global Value Chains at the Time of Covid-19
No full textThe pandemic we are experiencing is, despite its temporary nature, likely to leave a permanent sign on the global trade system. Measures to contain contagion have revealed the greater vulnerability of firms operating in global value chains (GVCs) and especially those located in first-hit countries. The risk is that production reshuffling made possible by automation will increase, and that nations will see incentives for changing the distribution of manufacturing around the globe. Furthermore, Covid-led trade restrictions may trigger a new wave of protectionism, impacting disproportionately on those countries without the manufacturing capacity to provide their populations with medical products
La dimensione dinamica della salute e della sicurezza sul lavoro nel contesto locale. Sistemi produttivi, modelli di prevenzione e profili penali
No full textCuratela dell'opera collettanea. Il volume contiene gli atti del convegno finale e i risultati del progetto di ricerca interdisciplinare
“Safer Work - Salute e sicurezza nei luoghi di lavoro
del territorio modenese: organizzazione, gestione
dei rischi e responsabilità”, finanziato dalla
Fondazione di Modena nell’ambito del Bando FAR
- Fondo di Ateneo per la ricerca Mission Oriented
2022, che aveva l’obiettivo di indagare i rapporti
tra l’apparato normativo in materia sicurezza sul
lavoro, i dati e le dinamiche degli infortuni occorsi
negli ultimi anni nelle aziende del territorio modenese
e le attività poste in essere dagli organi di
vigilanza, al fine di valutare l’efficacia dei modelli
di gestione dei rischi e rafforzare percorsi partecipativi
e di confronto tra gli attori della prevenzione,
anche in base al settore produttivo di afferenza
e alle modalità di lavoro. L’opera contiene una
varietà di contributi che cercano di affrontare da
diverse angolature il reticolo di problemi e di questioni
aperte che riguardano la tutela della salute
e della sicurezza dei lavoratori: organizzazione
dell’impresa, trasformazioni del lavoro, obbligo di
formazione, profili penali della sicurezza sul lavoro,
responsabilità degli enti, tutela per i rischi psicosociali

Assessing the Carasau Bread Doughs Microwave Spectra
Full text linkCarasau bread (CB) is a traditional Sardinian flatbread with significant market potential, driving the need for advanced quality monitoring solutions in its production. Recent advancements in automation and engineering have enhanced process control, but a comprehensive understanding of CB dough properties remains essential. Dielectric spectroscopy (DS), particularly in the microwave (MW) range, has emerged as a non-destructive, cost-effective tool for food characterization, providing insights into microstructure and composition. MW DS has been applied to assess fermentation dynamics and ingredient influence in CB doughs, with previous studies modeling dielectric properties using a third-order Cole–Cole model up to 8.5 GHz and later extending to 20 GHz. Despite these advancements, the repeatability, reliability, and consistency of MW DS measurements on CB doughs have not been systematically assessed. This study aims to fill this gap by analyzing MW DS measurements on ten CB dough samples with standard composition (water 50%, yeast 1.5%, salt 1.5%) in the 0.5–6 GHz range, both before and after leavening, for 10 different samples and a total of 100 measurements. Even though the correlation between spectra is high, and even if the coefficient of variation is below 5% before leavening, the z-score analysis and the kernel density estimation highlighted that the distribution of dielectric data is heterogeneous, showing that variability across samples exists, especially after leavening. Finally, the influence of pressure, temperature, and relative humidity was excluded. This statistical evaluation of MW DS measurement provided critical insights into the robustness of MW DS for industrial applications
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
