No full textA La autonomía del método biográfico, las historias de vida como praxis interactiva, el carácter participativo de la investigación con fuentes orales, la propuesta de leer una sociedad a través de una biografía, son principios epistemológicos cuyos fundamentos teóricos deben bastante a las aportaciones del sociólogo italiano Franco Ferrarotti. Catedrático en la Universidad de Roma "La Sapienza", el autor se inscribe en la rica tradición de la escuela italiana de historia oral, que desde Gramsci, De Martino y Bosio ha utilizado las autobiografías como un acceso privilegiado a las clases subalternas. Sus libros Storia e storie di vita (1981) y La storia e il quotidiano (1985) constituyen obras fundamentales para los que trabajan con fuentes orales. La presente entrevista recoge los planteamientos del autor sobre la relación entre historias de vida y ciencias sociales.The autonomy of the biographical method, the interactive praxis of life stories, the participative character of the research based on oral sources, the proposal of reading a society through biographies, are all epistemological principles which theoretical foundations are in debt with the contributions of Italian sociologist Franco Ferrarotti.

A Comparison of the Meta Quest Pro and HTC Vive Focus 3 Eye-Tracking Systems: Analysis of Data Accuracy and Spatial Precision
No full textThe rise of Virtual Reality has highlighted eye gaze as a key interaction method. Data reliability becomes critical in this context, with gaze accuracy and precision serving as leading indicators of data quality. This study compared the spatial accuracy and precision of Meta Quest Pro and HTC Vive Focus 3 headsets using eye movement data collected during a subjective experiment involving 30 users. Participants were asked to look at visual stimuli placed in a virtual environment under both head-free and head-constrained conditions. The stimuli were positioned at various locations and distances from the users. The analysis revealed inconsistencies between manufacturer-provided data, obtained under ideal conditions, and data collected in different settings. Moreover, the results showed greater spatial accuracy for Meta Quest Pro and higher spatial precision for HTC Vive Focus 3. This study aims to offer an extensive examination of the performance of these systems, thus assisting researchers in choosing suitable eye-tracking technology for diverse applications

Bilingualism and language contact in 16th-century Northern Italy. Some external evidence for the phonological history of French
No full textThe paper aims to present some lesser-known evidence relevant to the phonological history of French gathered through the bilingual texts in the Opera Jocunda by Giovan Giorgio Alione, published in Asti, Piedmont, Northern Italy, in 1521. In these texts, French is spelled using the graphemic system that the author employed primarily to write in his native Gallo-Italian dialect, thus rendering French phonetically transparent through linguistic comparison. This makes it possible to sketch a phonetic profile of the French known to the author at the end of the Middle French period. The evidence gathered seems to point to a more conservative variety if compared to the commonly reconstructed relative chronology of the phonological history of French. Some hypotheses in a framework of historical sociolinguistics and language contact are put forward to explain this discrepancy
Heat Release Rate Markers for the Adelaide Jet in Hot Coflow Flame
No full textIn the present work, the correlation between the Heat Releaser Rate (HRR) and species mole fractions and net reaction rates is studied. The PaSR closure model is employed in a RANS framework to implement a detailed kinetic scheme, including the excited species OH*, used as a HRR marker. The effect of oxygen dilution on the combustion regime is investigated, as it can lead to Moderate or Intense Low-Oxygen Dilution (MILD) conditions. Two cases with different levels of oxygen concentration are analyzed. The results suggest the possibility of combining chemical species to construct an appropriate scalar to achieve better correlation with the HRR. It is found that typical markers such as radicals O, OH, OH* correlate fairly well with the HRR but improved correlations can be achieved with appropriate species mole fractions combinations, particularly for the MILD region of the flame.This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme under grant agreement no. 714605.

On the identification of the leading sensory cue in mulsemedia VR applications
No full textThis work aims to investigate the existence of a leading sensory cue in a mulsemedia Virtual Reality application involving three senses: vision, hearing, and touch. On the one hand this study can help in gaining insights into how the different senses contribute to mulsemedia applications in Virtual Reality. On the other, the identification of the leading cue could drive the optimization of Virtual Reality applications in terms of Quality of Experience, stimuli definition, and transmission requirements. In this paper, we present a mulsemedia experimental protocol for a subjective test aimed at identifying the material of a virtual object. We present the encountered challenges and describe and discuss the obtained results
Changement social et sciences sociales en Italie
No full textFranco Ferrarotti : Sozialer Wandel und soziale Wissenschaften in Italien. Anhand einer Untersuchung der Entwicldung der italienischen Gesellschaft als eines Prozesses der Industrialisierung und der Verstadterung, wird die Kluft zwischen traditionellen Strukturen und Anpassung der Menschen an dièse neue technische Gesellschaft gezeigt. Der Verfasser geht aber iiber das Thema hinaus, um die empirische Forschung in Italien kritisch zu analysieren und einige Wege anzudeuten, die seiner Ansicht nach diese Forschung gehen sollte, wollte sie diesen unabwendbaren sozialen Wandel erleichtern.Франко Ферраротти: Социальные изменения и социальные науки в Италии.
Автор изучает требования италиянского общества под углом зрения: урбанизация-индустриализация, и указывает на разрыв между традиционными структурами общества и приспособлением индивидумов к этой технической цивилизации. Выходя за рамки этого вопроса, он дает критический анализ эмпирическому исследованию в Италии и указывает на те пути, благодаря которым может легко произойти необратимый процесс текущего социального изменения.Franco Ferrarotti : Social change and social sciences in Italy.
The author studies the evolution of the Italian society from the point view of urbanization and industrialization and points out the divorce the traditional structures of this society and the individuals' adaptation to technical civilization. Going further, he makes a critical analysis of research in Italy and suggests some means by which it could contribute ease the irreversible process of the social change in progress.Franco Ferrarotti : Mutación social y ciencias sociales en Italia.
Estudia el autor la evolución de la sociedad italiana bajo el aspecto de la urbanization-industrialization, y revela el divorcio entre las estructuras tradicionales de la sociedad y la adaptación de los individuos a esa civilización técnica-práctica. Traspasando ese cuadro, háce el autor un análisis crítico de la investigation empírica en Italia e indica las vias segun las cuales tal investigación podría contribuir a facilitar el proceso irreversible de la mutaciónFerrarotti Franco.

Stress Assessment for Augmented Reality Applications Based on Head Movement Features
No full text: Augmented reality is one of the enabling technologies of the upcoming future. Its usage in working and learning scenarios may lead to a better quality of work and training by helping the operators during the most crucial stages of processes. Therefore, the automatic detection of stress during augmented reality experiences can be a valuable support to prevent consequences on people's health and foster the spreading of this technology. In this work, we present the design of a non-invasive stress assessment approach. The proposed system is based on the analysis of the head movements of people wearing a Head Mounted Display while performing stress-inducing tasks. First, we designed a subjective experiment consisting of two stress-related tests for data acquisition. Then, a statistical analysis of head movements has been performed to determine which features are representative of the presence of stress. Finally, a stress classifier based on a combination of Support Vector Machines has been designed and trained. The proposed approach achieved promising performances thus paving the way for further studies in this research direction
