Experiences and teaching physics with the IBSE method in primary school
Get PDFWe present the methodologies used, the main activities, the docu- mentation and evaluation methods used in an astronomy activity proposed to chil- dren in a 5th grade class of an Italian Primary School. The main objective was to test whether the approach used (based on the IBSE method) could develop mean- ingful and long-lasting science skills in children and could increase their interest in disciplines such as physics and science. The methodology, based on Inquiry, involved moments of experimentation, hypothesis formulation, model building, dis- cussion and comparison with peers. The Inquiry course lasted about 40/45 hours and had as its main focus the Moon and the main phenomena concerning it: light and shadows, lunar phases, eclipses, and space-time dimensions of Moon-Earth
Prime Annotazioni e Riflessioni sulla Promozione della Scienza Aperta
Get PDFNella relazione sono presentate alcune riflessioni scaturite dai seminari e webinar organizzati dal Centro Interdipartimentale per l’Etica e l’Integrità nella Ricerca (CID Ethics) del Consiglio Nazionale delle Ricerche (CNR) sul tema della Scienza Aperta (Open Science) anche alla luce della recente pubblicazione del Piano Nazionale per la Scienza Aperta (PNSA) nell’ambito del Programma Nazionale della Ricerca (PNR) 2021-2027
La dimensión jurídica del Espacio Europeo de la Investigación
Get PDFLas fuentes jurídicas de la Unión Europea establecen que para fortalecer sus bases científicas y tecnológicas es necesario realizar un Espacio Europeo de la Investigación es decir un contexto cultural, político, económico, y sobre todo ético y normativo, en el cual “los investigadores, los conocimientos científicos y las tecnologías circulen libremente” (artículo 179 Tratado de Funcionamiento de la Unión Europea). El presente libro quiere estudiar las consecuencias jurídicas de la construcción del Espacio Europeo de la Investigación, especialmente sobre los derechos y obligaciones de los investigadores y de las investigadoras, así como sobre los derechos de las personas involucradas en la actividad científica, en particular los menores y las personas vulnerables. La obra se refiere también a la disciplina jurídica de los bienes materiales e inmateriales y a la reglamentación de los contratos que tienen por objecto la investigación científica. Además, el libro analiza el método de construcción de las normas jurídicas y éticas que reglan la actividad científica
Revisiter la justice procédurale en contexte policier : une revue narrative de ses facettes conceptuelles et opérationnelles
Get PDFCet article explore la justice procédurale en criminologie, en particulier en contexte policier. Cette notion se décompose typiquement en quatre concepts, respect, participation citoyenne, neutralité, et fiabilité des motifs. Toutefois, leur mise en pratique présente plusieurs défis conceptuels. Ceux-ci complexifient la tâche de développer des outils de mesure fiables. Des suggestions visant à améliorer les mesures sont avancées, en particulier au regard du recours prédominant de questionnaires quantitatifs. Ces questionnaires comportent leur lot d’inconvénients qui justifient la nécessité de les repenser. Des solutions sont proposées pour obtenir des mesures plus précises et fiables. En conclusion, l'article met en avant l'importance cruciale de la collaboration des forces de l'ordre dans la recherche. L'amélioration des mesures et la coopération policière se révèlent indispensables pour approfondir notre compréhension de la justice procédurale dans le contexte policier
The gravitational wave and short gamma-ray burst GW170817/SHB170817A
No full textThis event, so far unique, beautifully confirmed the standard views on the gravitational waves produced by a merger of two neutron stars, but its electromagnetic multi-wavelenth observations disagreed with the numerous initial versions of the “standard fireball model(s)” of gamma ray bursts. Contrariwise, they provided strong evidence in favour of the “cannonball” model. Most uncontroversially,
a cannonball was observed at radio wavelengths, with an overwhelming statistical significance (>17 σ), and travelling in the plane of the sky, as expected, at an average apparent superluminal velocity Vapp ∼ 4 c
pyArchInit at Castelseprio: progressive adoption of an integrated managing system for archaeological field data
Get PDFIn the framework of the project Castelseprio, centre of power, the authors began excavating the structure known as Casa Piccoli in 2021. The area, already investigated by Piccoli in the 1970s, presents itself as an interesting case study for the application of an open and integrated solution for the management of stratigraphic data, specifically pyArchInit. Being an academic excavation project and, therefore, characterized by both research and training issues, it was decided to progressively and incrementally include the use of pyArchInit within the documentation protocols on site and post-excavation, over the three years of the permit granted by the Ministry of Culture for the excavations. Master's degree students who participated in the excavation, at the end of the planned period, will have the basic skills to use the plugin also in a professional environment. At the end of the first two years of implementation, a SWOT analysis will show the results obtained within the site for both training and research purposes
MASPAG & pyArchInit, the newborn collaboration of Sapienza and adArte in the Sultanate of Oman
Get PDFDuring the fieldwork season in November 2021-March 2022, the Missione Archeologica della Sapienza nella Penisola Arabica e nel Golfo (MASPAG), as part of the research activities supported and financed by the Great Excavations of Sapienza since 2019 and MAECI since 2022, planned and launched a new landscape archaeological project in the Sultanate of Oman. The first survey was carried out in an area of the Al Batinah South Governorate unknown to archaeology, combining remote-sensing and ground verification activities. This operation also saw the first result of the collaboration between the MASPAG research group and adArte srl, developer of pyArchInit open sources plugin for QGIS. The first season of the survey not only made it possible to estimate the archaeological potential of the study area, but also served as a workshop, opening a dialogue between universities and private companies, to discuss open source solutions in archaeology
Sharing structured archaeological 3D data: open source tools for artificial intelligence applications and collaborative frameworks
Get PDFThis paper focuses on collaborative methods and open source tools aimed to analyze and query 3D photogrammetric models of ancient architectures. The processing of virtual models led to the constitution of a training dataset of around 1300 wall facing stones from four archaeological sites in Crete. Through a purposely-conceived add-on of the open source software Blender, some algorithms expressed in Python are able to extract archaeologically significant features and to perform processes of Machine Learning and data mining. The resulting data are imported into a dedicated DB managed through a web application based on the open source framework Django. This workflow addresses some peculiar challenges of the application of Artificial Intelligence to archaeological heritage: the lack of training dataset, particularly related to architecture; the lack of best practices for geometry processing and analysis of 3D data; the use of poorly predictive data in semi-automatic processes; the sharing of data into the scientific community; the importance of the open source technology and open data
Challenges in research community building: integrating Terra Sigillata (Samian) research into the Wikidata community
Get PDFIn 2020, the Samian Research database began a process of integrating its data within Wikidata through the creation of a set of Samian Research Wikidata items, including Samian Ware Discovery Sites, Samian Ware kiln sites and kiln regions, comprising accurate or approximate geospatial information and a backlink to the Linked Open Data hub archaeology.link. This approach of creating designated Wikidata items is an efficient way to map the enormous geographic reach of our subject and to call attention to many European archaeological sites and excavations that hitherto lacked a Wikidata identifier. The site of Corinth illustrates an exemplary issue to be solved: ambiguity and different archaeological concepts and ideas. E.g., is it correct to merge Corinth as a Samian Ware Discovery Site with the archaeological site of ancient Corinth? To solve the issue, the broader Wikidata community must be enlisted. This paper describes the challenges in the use case of Corinth and offers solutions within Wikidata
Lo studio di siti archeologici di alta quota: metodologia e risultati del modello predittivo in ambiente GIS applicato nelle Valli di Lanzo (Piemonte, Italia)
Get PDFThe aims of TPAA Project (Traces Prehistoric in the Alpine Environment) are the research, promotion and protection of the archaeological heritage in the Lanzo Valleys in Graian Alps, Western Alps (Turin, Piedmont, Northwest Italy). This paper illustrates the GIS predictive model results for the identification of archaeological sites in Lanzo Valleys and the 2019-2020 field survey. The archaeological data stem from occasional findings or traces of rock art. The aim of the GIS predictive model is to identify Potential Archaeological areas for the presence of archaeological sites and to hypothesize any reconstruction of human frequentation dynamics in Western Alps. Predictive GIS model has been elaborated through the interpolation and interpretation of the different environmental and archaeological data available. In the GIS predictive model, criteria such as the geomorphology, distance to water resources, aspect, slope and the use of land were considered. Also, the methodology is an evolution of the one that has already been successfully employed in the Sessera Valley. The results of the GIS model are compared with archaeological data collected during field surveys in the Potential Archaeological areas
