Improvement in educational performance through wearable-based flow predictive models

Flow Theory has been used to study motivation in educational activities. However, few studies use physiological data to uncover unknown aspects of said data in any context, and isolated individuals are involved as well. In this paper, we present some of the results obtained from two control groups corresponding to two full primary education classrooms, as well as their teacher, using a quasi-experimental design. They participated in two training activities with different instructional designs and three different STEAM subjects: graphic design, video game design using Roblox Studio, and educational robotics. In this sense, the heart rate, its variability, data from accelerometers, and the educational activities carried out by the teacher have been automatically recorded for each participant at every second. To achieve this, we used smartwatches connected to Polar H10 sensors as well as our own apps. At the end of each session, everyone answered the Flow FKS and EduFlow prevalence questionnaires, and the teacher kept a class journal. Through this, we aim to understand whether the Flow Theory models derived from the FKS and EduFlow scales are valid from a physiological standpoint, as well as to develop classification and predictive models based on artificial intelligence that will allow for educational performance improvement of students in future research

Automatic determination of the Atterberg limits with machine learning

In this study, we determine the liquid limit (Wt), plasticity index (PI), and plastic limit (Wp) of several natural fine-grained soil samples with the help of machine-learning and statistical methods. This enables us to locate each soil type analysed in the Casagrande plasticity chart with a single measure in pressure-membrane extractors. These machine-learning models showed adjustments in the determination of the liquid limit for design purposes when compared with standardised methods. Similar adjustments were achieved in the determination of the plasticity index, whereas the plastic limit determinations were applicable for control works. Because the best techniques were based in Multiple Linear Regression and Support Vector Machines Regression, they provide explainable plasticity models. In this sense, (Equation presented), and (Equation presented). So that, we propose an alternative, automatic, multi-sample, and static method to address current issues on Atterberg limits determination with standardised tests.En este estudio, determinamos el límite líquido (), el índice de plasticidad (PI) y el límite plástico () de suelos naturales finos con ayuda de machine-learning y métodos estadísticos. Ello permite localizarlos en la Carta de Plasticidad de Casagrande con una sola medida en extractores de presión-membrana. Los modelos de machine-learning mostraron ajustes en la determinación de apropiados para propósitos de diseño, comparados con métodos estandarizados. Ajustes similares se alcanzaron en la determinación de PI, mientras que las determinaciones de permiten ajustes apropiados para trabajos de control. Debido a que las técnicas más apropiadas se basaron en Regresión Lineal Múltiple y Máquinas de Soporte de Vectores, aportaron modelos de plasticidad explicables. En este sentido, =(9.94±4.2)+(2.25±0.3)∙4.2,=(−20.47±5.6)+(1.48±0.3)∙4.2+(0.21±0.1)∙y=(23.32±3.5)+(0.60±0.2)∙4.2−(0.13±0.04)∙. Por consiguiente, proponemos un método alternativo, automático, estático y multimuestra para enfrentar problemas frecuentes en la determinación de los Límites de Atterberg con ensayos normalizados

A new assemblage of late Neanderthal remains from Cova Simanya (NE Iberia)

This study presents an exceptional collection of 54 Late Pleistocene human remains that correspond to at least three Neanderthal individuals from Simanya Gran, the main gallery of Cova Simanya, located in the northeastern Iberian Peninsula. The collection comprised 53 unpublished remains that were unearthed during the 1970s and an additional tooth discovered during 2021 excavations. The specimens represent an adult with a small stature, a periadolescent aged approximately 11.5 years, and an immature individual aged approximately 7.7 years, thus offering a more complete demographic perspective. The collection encompasses diverse anatomical parts including upper and lower dentition, mandible, vertebrae, and limb bones from both the upper and lower extremities. Attempts to extract aDNA were unsuccessful. Renewed archaeological investigations at Cova Simanya have facilitated the reevaluation of the original stratigraphic context of these remains, leading to the discovery of the additional tooth, aligning with the periadolescent individual. This assemblage is currently the most extensive Neanderthal collection from the northeastern Mediterranean Iberia, offering invaluable insights into the morphology and evolutionary trajectory of Late Pleistocene hominins. Hence, Simanya Neanderthals will enhance our understanding of Neanderthal demographics and evolution, paving the way for an in-depth examination of the morphological diversity and evolutionary context of Iberian Neanderthals.This research was funded by the Spanish Ministry of Science and Innovation through the projects PID2021-122356NB-I00 (MNCN-CSIC, AR), PID2020-113960GB-I00 (UB, JF), PID2021-124590NB-I00 (MCNB, CL-F), PID2019-103987GB-C31 (IPHES-CERCA), and PID2021-126004NB-100 (IBE-UPF-CSIC, TM-B); the AGAUR through the research groups 2021 SGR 01237 (IPHES-CERCA, EA), 2021 SGR 00337 (UB, JF), and 2021 SGR 00177 (IBE-UPF-CSIC, TM-B); the Culture Department of the Generalitat de Catalunya through the project ARQ001SOL-172-2022; and the Diputació de Barcelona and the Fundación Palarq.

The occupation of Benzu Cave (Ceuta) by Neolithic and Bronze Age Societies

Abstract This study presents the results of the archaeological investigation in Benzú Cave, located on the North African shore of the Strait of Gibraltar. The archaeological deposits, approximately 1 m deep, belong to two occupational levels dated to theNeolithic and the Bronze Age. Awide range of artifacts was found, and this led to an interdisciplinary study that led us to reach new conclusions concerning the material life, subsistence economy, and environment of the Neolithic and Bronze Age societies in northern Africa and the southern Iberian Peninsula.Résumé Cette étude présente les résultats des recherches archéologiques menées dans la grotte de Benzú, située sur la rive nord-africaine du détroit de Gibraltar. Les gisements archéologiques, d'environ un mètre de profondeur, appartiennent à deux niveaux d'occupation datant du néolithique et de l'âge du bronze. Une large gamme d'artefacts ont été trouvés, ce qui a conduit à une étude interdisciplinaire qui nous a amenés à tirer de nouvelles conclusions concernant la vie matérielle, l'économie de subsistance et l'environnement des sociétés du Néolithique et de l'Age du Bronze en Afrique du Nord et au sud de la Péninsule Ibérique
