Evaluating Pre-Trained Transformers on Italian Administrative Texts

In recent years, Transformer-based models have been widely used in NLP for various downstream tasks and in different domains. However, a language model explicitly built for the Italian administrative language is still lacking. Therefore, in this paper, we decided to compare the performance of five different Transformer models, pre-trained on general purpose texts, on two main tasks in the Italian administrative domain: Name Entity Recognition and multi-label document classification on Public Administration (PA) documents. We evaluate the performance of each model on both tasks to identify the best model in this particular domain. We also discuss the effect of model size and pre-training data on the performances on domain data. Our evaluation identifies UmBERTo as the best-performing model, with an accuracy of 0.71, an F1 score of 0.89 for multi-label document classification, and an F1 score of 0.87 for NER-PA

Use of mixed study techniques in the evaluation of coastline dynamics - the “Porto Cesareo” MPA case of study

In recent decades, the much-discussed climate changes with the consequent variations in sea and weather conditions and the rise of the mean sea level are causing an indisputable set of negative actions on the entire coastal system mainly due to the increase of the erosive phenomenon along the shorelines. These critical scenarios have a major impact even on a local scale, and because of that, we decided to study a well knows tract of rocky/sandy mixed coast, in a highly anthropized area, even if located inside the “Porto Cesareo” Marine Protected Area (MPA) (Ionian Sea, Gulf of Taranto, Puglia Region, Italy). The high naturalistic and archaeological value of this area calls for a greater institutional effort in the study of erosional phenomena. Several historical documents from other studies point out that this coastal area is an ideal place for this kind of research. The effects of coastal erosion and anthropic pressures along this tract of coast require adequate efforts for a consistent and rapid evaluation of the coastal dynamics. The methodologies proposed in this work are based on mixed techniques from different fields of study, integrating recent aero photogrammetry surveys with drones, aerial images acquired by the Italian Military Geographic Institute (IGM), elaboration of paleoshorelines related by underwater archaeological markers and their dating, and finally on the elaboration of satellite products useful for the study of vast areas. The monitoring of coastal areas and the evaluation of shoreline dynamics are core topics in the implementation of managing actions of decision makers on a local, regional, national, and international scale, above all in places like the chosen one, inside an MPA. Remote sensing through the use of RPAS (Remotely Piloted Aircraft Systems or Drones) has proved to be very useful for identifying phenomena that act on a small spatial scale and in supporting and implementing protective measures according to the adaptive management approach, through multi-year surveys on habitats of conservation interest [18]. For the implementation of fine-scale monitoring actions, we have chosen products from the Sentinel satellite of the Copernicus constellation (European Space Agency - ESA). In this context, the use of satellite products provides a recurrent view of the ground, useful in the short and long-term monitoring of changes in wide coastal areas, and in particular, offers a coastline positioning evaluation in near real-time. Local monitoring actions performed in recent years have already shown an erosive trend in the past decades, and even, negative forecasts for the next decade, so further surveys with mixed methodologies could be crucial in the evaluation of the evolution of this particular coastal area by local authorities

Challenging specialized transformers on zero-shot classification

This paper investigates the feasibility of employing basic prompting systems for domain-specific language models. The study focuses on bureaucratic language and uses the recently introduced BureauBERTo model for experimentation. The experiments reveal that while further pre-trained models exhibit reduced robustness concerning general knowledge, they display greater adaptability in modeling domain-specific tasks, even under a zero-shot paradigm. This demonstrates the potential of leveraging simple prompting systems in specialized contexts, providing valuable insights both for research and industry

Influence of major mergers on the radio emission of elliptical galaxies

We investigate the influence of major mergers on the radio emission of elliptical galaxies. We use a complete sample of close pairs, which contains 475 merging and 1828 non-merging paired elliptical galaxies of M_r<-21.5 selected from the Sloan Digital Sky Survey. In addition, a control sample of 2000 isolated field galaxies is used for comparison. We cross-identify the optical galaxies with the radio surveys of FIRST and NVSS. We find that the radio fraction of merging paired galaxies is about 6%, which is slightly higher than the 5% obtained for non-merging paired galaxies, although these values are consistent with each other owing to the large uncertainty caused by the limited sample. The radio fraction is twice as that of isolated galaxies, which is less than 3%. Radio emission of elliptical galaxies is only slightly affected by major mergers, but predominantly depends on their optical luminosities. Therefore, merging is not important in triggering the radio emission of elliptical galaxies.Comment: 5 pages, 5 figures, 1 table, accepted for publication in A&A, minor change

Gpr investigation at the archaeological site of le cesine, lecce, italy

In this contribution, we present some results achieved in the archaeological site of Le Cesine, close to Lecce, in southern Italy. The investigations have been performed in a site close to the Adriatic Sea, only slightly explored up to now, and where the presence of an ancient Roman harbour is alleged on the basis of remains visible above all under the current sea level. This measurement campaign has been performed in the framework of a short-term scientific mission (STSM) performed in the framework of the European Cost Action 17131 (acronym SAGA), and has been aimed to identify possible points where future localized excavation might and hopefully will be performed in the next few years. Both a traditional elaboration and an innovative data processing based on a linear inverse scattering model have been performed on the data

Faint, Evolving Radio AGN in SDSS Luminous Red Galaxies

We detect and study the properties of faint radio AGN in Luminous Red Galaxies (LRGs). The LRG sample comprises 760,000 objects from a catalog of LRG photometric redshifts constructed from the Sloan Digital Sky Survey (SDSS) imaging data, and 65,000 LRGs from the SDSS spectroscopic sample. These galaxies have typical 1.4 GHz flux densities in the 10s-100s of microJy, with the contribution from a low-luminosity AGN dominating any contribution from star formation. To probe the radio properties of such faint objects, we employ a stacking technique whereby FIRST survey image cutouts at each optical LRG position are sorted by the parameter of interest and median-combined within bins. We find that median radio luminosity scales with optical luminosity (L_opt) as L_1.4 GHz ~ L_opt^(beta), where beta appears to decrease from beta ~ 1 at z = 0.4 to beta ~ 0 at z = 0.7, a result which could be indicative of AGN cosmic downsizing. We also find that the overall LRG population, which is dominated by low-luminosity AGN, experiences significant cosmic evolution between z = 0.2 and z = 0.7. This implies a considerable increase in total AGN heating for these massive ellipticals with redshift. By matching against the FIRST catalog, we investigate the incidence and properties of LRGs associated with double-lobed (FR I/II) radio galaxies.

Millstones as indicators of relative sea-level changes in northern Sicily and southern Calabria coast lines, Italy

New data are presented for late Holocene relative sea-level changes in two coastal sites of Sicily and Calabria, southern Italy. Reconstructions are based on precise measurements of submerged archaeological remains that are valuable indicators of past sea-level position. The archaeological remains are millstone quarries carved on sandstone coastal rocks and nowadays partially submerged which, to the authors’ knowledge, are used for the first time as sea-level markers. Millstones of similar typology are located on the coast of Capo d’Orlando (northern Sicily) and Capo dell’Armi (southern Calabria). When the archeologically-based sea-level position is compared with the shoreline elevation provided by geological markers (Holocene beachrock, Late Pleistocene marine terraces), a refined understanding of relative sea-level changes and rates of vertical tectonic movements for these coastline locations is gained

Increased carotid intima-media thickness and stiffness in obese children

Summary (Abstract not available):Obesity in childhood increases the risk of atherosclerotic disease and death in adulthood. We studied 100 children with obesity and 47 healthy age-mathced control subjects, mean age 10 years of both groups. Biochemical parameters describing lipoprotein and glucose metabolism were measured. Quantitative B-mode ultrasound examination of common carotid arteries was performed. Carotid thickness and stiffness were significantly increased in obese children as compared to nonobese ones, independently of traditional cardiovascular risk factors. Obesity should be regarded as a disease with vascular implications even in young age

UNDERGROUND HERITAGE DOCUMENTATION: THE CASE STUDY OF GROTTA ZINZULUSA IN CASTRO (LECCE-ITALY)

3D documentation of the Underground Built Heritage (UBH) is always fundamental for knowledge, management, conservation, and enhancement of cultural heritage, but the challenges involved in documenting this kind of site are many and various, With the aim of providing an accurate and reliable representation of the surveyed area without employing time-consuming processes, Mobile Mapping Systems (MMSs) based on SLAM (Simultaneous Localization And Mapping) technology have now the potential to overcome these challenges, proving to be a useful alternative to traditional surveying techniques. The underground site of Grotta Zinzulusa in Castro (LE), Italy, is an anchialine cave system difficult to access and document due to its narrow passages, large rooms, and poor illumination. Within this case study, the effectiveness of using an MMS approach, employing the STONEX&reg; X120GO SLAM Laser Scanner system, to document the cave system and integrates the data with those obtained from other traditional geomatics techniques, such as UAS (Uncrewed Aerial System) and TLS (Terrestrial Laser Scanning) surveys, has been proved. The study aims to define the best practices and operational methodologies for enhancing the speediness, usability, and cost-effectiveness of using MMSs in underground settings for 3D documentation of heritage sites to provide metrically correct and accurate products for researchers, scientists, and the wider public
