Tra virtù teologale e principio speranza. Rinvii e intersezioni: Charles Peguy, Ernst Bloch, Paul Ricoeur, Ernesto Balducci.
No full textPrendendo spunto da una poesia di Charles Peguy sulla virtù teologale della speranza, si prende in esame la sua intrecciata valenza inframondana-secolare e trascendentale-escatologica. E', poi, ricostruito, nel contesto delle grandi trasformazioni economiche, sociali e culturali tra Ottocento e Novecento, il dibattito teologicvo-pastoraledalla Rerum Novarum alla Gaudium et Spes, con i contributi di riflessione foilosofica di Chjarles Peguy, Jurghen Moltmann, Erst Bloch, Paul Ricoeur e Ernesto Balducci

Preliminary Evaluation of Machine Learning Approaches for PANTONE Color Classification with the SENSIPATCH wearable system
No full textPrecise color classification is crucial in industries such as art, design, manufacturing, textile, and biomedical applications. It ensures consistency, meets stringent standards, and aids in functional decision-making where accurate color distinction is essential. The SENSIPATCH wearable sensor system presents an end-to-end solution for spectral analysis with its multi-channel scattering spectrometer and SENSIPLUS microsensor, providing a seamless integration of sensor data acquisition, processing, and machine learning. This study investigates the efficacy of the SENSIPATCH sensor in accurately classifying PANTONE card colors. By leveraging spectral data, the study aims to enhance precision in color classification across various sectors and explore future biomedical applications, specifically melanoma detection. The primary objectives are to evaluate the SENSIPATCH sensor's accuracy in PANTONE color classification, develop and refine a Multi-Layer Perceptron (MLP) model to interpret the spectral data, and assess the potential of this technology for complex classification tasks in different fields. The methodology involves a controlled experimental setup, extensive data collection under varying lighting conditions, and the application of machine learning algorithms for color classification. Results demonstrate the superior performance of the MLP model in color classification compared to KNN, SVM, and Random Forest models

Geopolitical risks, critical materials and energy transition: Insights from wavelet analysis
No full textThis paper investigates how the prices of selected energy transition-related commodities respond to geopolitical risks, with particular attention to the suitability of a widely used geopolitical risk index in relation to the commodities included in the dataset. From a methodological perspective, the analysis is conducted via a wavelet-based method. The dataset includes natural gas, copper, palladium, and cobalt futures prices, whose time series cover a fourteen-year time span (2010-2024), while geopolitical risk is measured through the well known text-based geopolitical risk (GPR) index by Caldara and Iacoviello. The study is supported by an in-depth geopolitical discussion, analyzing events and dynamics relevant to the current international context. Our investigation shows different degrees of correlation between geopolitical risk and the above-mentioned commodities. From an overall perspective, commodities with a long-standing history of application tend to exhibit a more straightforward connection with geopolitical dynamics. In contrast, those that have recently gained prominence in the energy transition — especially newer entrants — show weaker and less consistent signals. In this respect, despite its widespread use in the literature, we infer that the GPR index has certain limitations when used to explain dynamics affecting rare and critical elements — particularly those sourced from geographical areas that are not regularly covered by mainstream media. The issue of the GPR index's adequacy in such contexts appears to be largely overlooked in current academic sources. Recognizing that the energy transition is driving a paradigm shift from a geostrategic standpoint requires a critical awareness when employing such indexes. At the same time, it calls for rethinking how risk indexes are designed, so that they better reflect geopolitical phenomena linked to the new centers of gravity emerging from the energy transition. The results are directed towards policymakers and regulators, who are called upon to govern the energy transition with a focus on the availability of critical materials in the coming decades
