    Abstract As is known, Covid-19 has mobilized many scholars in the world who have framed the pandemic from the perspective of virology and epidemiology. In this work, drawing on various documentary sources, an anthropological analysis is proposed, which focuses exclusively on the beginning of the pandemic, in the months of January and February 2020. This choice makes it possible to grasp the social and political aspects that influenced the emergence of the problem, which must be placed in the political devices that have been used to unveil the anomaly and in the cultural models that make it possible to control order.

    Abstract Territories affected by environmental anomalies have recently arouse an interest of anthropological disciplines. Anthropology aims at understanding expressive practices of malaise, defense actions, performances of resistance and contrast, ways of perception and risk processing, and so forth, of the people involved. This article, based on archival, journalistic, judicial and legislative sources and on the first results of a research led on the city of Taranto, proposes an analytical path of historical and political anthropology. As a result, it is put forward an interpretative proposal of applied anthropology aimed at overcoming the gap between local risk perception and public control and mitigation policies.

    Abstract We introduce PolyDiff, the first diffusion-based approach capable of directly generating realistic and diverse 3D polygonal meshes. In contrast to methods that use alternate 3D shape representations (e.g. implicit representations), our approach is a discrete denoising diffusion probabilistic model that operates natively on the polygonal mesh data structure. This enables learning of both the geometric properties of vertices and the topological characteristics of faces. Specifically, we treat meshes as quantized triangle soups, progressively corrupted with categorical noise in the forward diffusion phase. In the reverse diffusion phase, a transformer-based denoising network is trained to revert the noising process, restoring the original mesh structure. At inference, new meshes can be generated by applying this denoising network iteratively, starting with a completely noisy triangle soup. Consequently, our model is capable of producing high-quality 3D polygonal meshes, ready for integration into downstream 3D workflows. Our extensive experimental analysis shows that PolyDiff achieves a significant advantage (avg. FID and JSD improvement of 18.2 and 5.8 respectively) over current state-of-the-art methods.

    Abstract A partire da alcune importanti sollecitazioni storiografiche di Ugo Fabietti si analizza la figura di James Mooney, studioso di origine irlandese che tra Ottocento e Novecento svolse tra i nativi d’America una significativa attività di ricerca quale antropologo del Bureau of American Ethnology. Ricostruito il percorso formativo e gli interessi di studio, messe in chiaro le specificità teoriche tese a superare i dettami dell’evoluzionismo, evidenziati taluni aspetti innovativi della ricerca di campo basati anche sull’uso pionieristico dei sistemi di registrazione audiovisuale, l’attenzione è focalizzata sui concetti di efficacia terapeutica e di libertà religiosa presenti nelle ricerche condotte da Mooney sui movimenti messianici (Ghost Dance) e sulle pratiche religiose (Peyote Religion). Mediante l’impiego di fonti documentarie molteplici e il confronto con la letteratura internazionale di riferimento, si analizzano i tratti portanti di un modo particolare di concepire il sapere antropologico, in cui la comprensione delle culture altre non è affatto disgiunta da una serrata attività pubblica di difesa dei nativi.

    Abstract Moving deep learning models from the laboratory setting to the open world entails preparing them to handle unforeseen conditions. In several applications the occurrence of novel classes during deployment poses a significant threat, thus it is crucial to effectively detect them. Ideally, this skill should be used when needed without requiring any further computational training effort at every new task. Out-of-distribution detection has attracted significant attention in the last years, however the majority of the studies deal with 2D images ignoring the inherent 3D nature of the real-world and often confusing between domain and semantic novelty. In this work, we focus on the latter, considering the objects geometric structure captured by 3D point clouds regardless of the specific domain. We advance the field by introducing OpenPatch that builds on a large pre-trained model and simply extracts from its intermediate features a set of patch representations that describe each known class. For any new sample, we obtain a novelty score by evaluating whether it can be recomposed mainly by patches of a single known class or rather via the contribution of multiple classes. We present an extensive experimental evaluation of our approach for the task of semantic novelty detection on real-world point cloud samples when the reference known data are synthetic. We demonstrate that OpenPatch excels in both the full and few-shot known sample scenarios, showcasing its robustness across varying pre-training objectives and network backbones. The inherent training-free nature of our method allows for its immediate application to a wide array of real-world tasks, offering a compelling advantage over approaches that need expensive retraining efforts.

    Abstract In recent years there has been significant progress in the field of 3D learning on classification, detection and segmentation problems. The vast majority of the existing studies focus on canonical closed-set conditions, neglecting the intrinsic open nature of the real-world. This limits the abilities of robots and autonomous systems involved in safety-critical applications that require managing novel and unknown signals. In this context exploiting 3D data can be a valuable asset since it provides rich information about the geometry of perceived objects and scenes. With this paper we provide the first broad study on 3D Open Set learning. We introduce 3DOS: a novel testbed for semantic novelty detection that considers several settings with increasing difficulties in terms of semantic (category) shift, and covers both in-domain (synthetic-to-synthetic, real-to-real) and cross-domain (synthetic-to-real) scenarios. Moreover, we investigate the related 2D Open Set literature to understand if and how its recent improvements are effective on 3D data. Our extensive benchmark positions several algorithms in the same coherent picture, revealing their strengths and limitations. The results of our analysis may serve as a reliable foothold for future tailored 3D Open Set methods.

    Abstract In the anthropological sciences, research on symbols is a relevant and well recognizable field of study. In most cases, symbolism has been analyzed above all in the magical-religious sphere. In the present study we propose an analysis of the symbolic construction processes in the secular field. Starting from environmental problems present in a region of Southern Italy, Campania, the article proposes a morphological and semantic analysis of waste fires. Considered as dead objects, domestic and industrial waste preserve a series of properties that generate social phenomena of risk and disease. By consulting digital, literary, iconographic sources, etc. the study offers an interpretation of symbols as factors of cultural destabilization and identity.

    Abstract In September 2018, the Agenzia Regionale per la Protezione dell’Ambiente di Puglia (“Apulia Regional Agency for the Preservation of the Environment”) detected a very high concentration of radon, a carcinogenic agent, in the schools of Tamburi, an area of Taranto. Based on the comparative use of numerous documentary sources and intense field research conducted in an industrialized town with a very high awareness of health risks, the study tackles the problem of the relationship between health and environment protection public bodies and the reactions of the people who live in the area. Moreover, starting from the analysis of contextual and symbolic aspects, the article focuses on the concept of risk perception showing that it is the product of a process of elaboration that configures syncretic and contingent constructions.
