Contextualizing the Cartographic Origins of Continental Drift: Antonio Snider-Pellegrini’s La Création et ses Mystères Dévoilés (1858) and Nineteenth-Century Transnational Scientific Networks

The continental drift theory proposed by Alfred Wegener in the early twentieth century was a pivotal advancement in our understanding of the Earth’s geological configuration and its graphical representation. However, already in 1858, the adventurer Antonio Snider-Pellegrini had published La Création et ses Mystères Dévoilés, which included the first-ever depiction of continental drift in two compelling globe maps, drawn by the planetary mapper Charles Bulard, illustrating the Earth’s surface...

Robust tools for three-way component analysis of compositional data

A brief overview of multilinear tools, robustification procedures and compositional data analysis for three-way arrays is followed by a detailed presentation on the use and applicability of the implemented functions by means of real data examples included in the R package rrcov3way. Two main functions are implemented, Parafac() and Tucker3(), which include alternative options to the standard least squares algorithm in order to properly calculate the models in case of data with outliers and/o...

Modeling relative competence in PISA: a compositional multiple factor analysis approach

This study presents a novel approach to analyzing student performance data from the OECD-PISA assessments, emphasizing relative variability over absolute achievement levels. Traditional analyses tend to focus on rankings and scale construction, often neglecting the underlying components of performance. In contrast, the proposed method adopts a compositional perspective to investigate how various cognitive domains contribute to individual outcomes, revealing patterns of association and t...

Formule dell’italiano accademico: rilevanza educativa e indicazioni didattiche

Nel contributo si discute la rilevanza educativa delle formule per l’italiano accademico. Considerando in particolare risultati e discussioni di recenti lavori inerenti alla descrizione e all’insegnamento del linguaggio formulare inglese, si danno alcune indicazioni per la didattica scolastica e universitaria dell’italiano accademico e si propongono relative domande di ricerca. Si offrono inoltre esempi delle formule prese in considerazione (sequenze ricorrenti, polirematiche e marcatori del ...

La antología prietopunk: el afrofuturismo caribeño en sus límites

This article aims to critically examine the Caribbean Afrofuturist science fiction anthology Prietopunk, published in 2022 thanks to the text compilation efforts of Dominican writer Aníbal Hernández Medina. First, this study provides an overview of Caribbean Afrofuturist trends over the past decade, also in relation to U.S. production. Second, it seeks to identify the “major” tendencies within Caribbean Afrofuturist literature, both in the texts included in the anthology and in the broader li...
