Laterally accreted deposits in low efficiency turbidites associated with a structurally-induced topography (oligocene molare group, tertiary piedmont basin, nw italy)

The origin of laterally accreted deposits in ancient deep marine successions is often controversial. Indeed, not always do these features imply the occurrence of meanders or high-sinuosity turbidite channels, but they can be generated by other causes, such as sediment-gravity-flow dynamics controlled by the morphology of tectonically confined mini-basins. This work discusses laterally accreted deposits composed of sharp-based, normally graded beds in a very small tectonically controlled mini-basin. These beds, characterized by a well-defined asymmetrical crosscurrent facies tract, form well-developed lateral-accretion surfaces dipping in directions ranging between W and SW, and perpendicular to the paleocurrents directed towards the N. For this reason, these deposits have always been interpreted as point bars related to meandering channels. A new detailed stratigraphic framework and facies analysis have led to an alternative interpretation, namely that these deposits record lateral deflections of small volume, longitudinally segregated turbidite dense flows against a structurally controlled morphological high. This interpretation is also supported by a comparison to other tectonically controlled turbidite systems that are characterized by higher degrees of efficiency but show similar laterally accreted deposits and cross-current facies tracts

Contained-Reflected Megaturbidites of the Marnoso-arenacea Formation (Contessa Key Bed) and Helminthoid Flysches (Northern Apennines, Italy) and Hecho Group (South-Western Pyrenees)

Contained-reflected beds deposited by fully-ponded or partially-reflected turbidity currents are important because their correct evaluation can give important indications on the degree of basin confinement and on the type, size and orientation of the morphological obstacle. Through a detailed facies analysis of various significant megabeds in the Marnoso-arenacea Formation, including the Contessa key bed, in the helminthoid flysches in the northern Apennines (Italy) and in the Pyrenees (megaturbidite MT5), this work proposes a depositional model that is well consistent with the recent experimental data available in the literature, discussing their strengths and limits. The Contessa and flysch megabeds fit very well with the experimental conditions because they are deposited in narrow and elongated confined basins characterized by axial flows. Indeed, in the proposed model, it is possible to recognize facies deposited by: 1) a basal underflow directed towards the bounding slope (Facies A), 2) an intermediate part of the flow characterized by lateral deflections (facies B1), 3) an upper well-developed reversing flow (facies B2) and 4) an uppermost residual reversing flow recording the final collapse of the fine-grained suspended load forming a poorly-sorted slurry facies C and a very thick mudstone unit D. Facies A, B1 and B2 are usually separated by very thin fine-grained muddy drapes rich in carbonaceous matter, which can be traced throughout the basin. These drapes - very common in contained and confined beds in these settings - can be related to internal density surfaces, along which decoupling processes, separating underflows from reversing overflows, can easily occur. Conversely, as the MT5 is characterized by a source transversal to an elongated narrow basin, the large flow volume versus basin capacity hinders the generation of reversing flows and rebound layers favoring the formation of fully-ponded pulsating overflows able to deposit alternations of laminated and massive units. This facies type can be observed in the basins that are characterized by axial flows only near the basin margins where the pulsating collapse of the reversing flow can dominate. This study shows that the integration of detailed field studies are essential to validate experimental data from an applicative point of view

Re-organization of assessment during the educational emergency in primary and secondary teaching: an Italian case

The educational crisis caused by the pandemic created an unprecedented need to reorganize teaching and learning processes, and the educational assessment became one of the thorniest issues in this rapid change; assessment reorganization entails layered complexities on micro, meso and macro levels. This research is contextualized in a larger digital ethnographic study of three different Italian teacher online communities, uncovering the experience from mixedmethods research. Following this research, a survey instrument was developed and launched. Current paper reports on the survey aiming to uncover the change in assessment practices during the educational emergency while reflecting on teachers’ beliefs on the assessment, the use of remote assessment methods before and during the pandemic, and its re-organization. Findings suggest a significant reorganization of assessment during the COVID-19 educational emergency in all school orders. Through all school orders, teachers perceived a reduction in the importance of assessment during the pandemic and, consequently, used most assessment techniques significantly less than before. However, different methods changed differently, with oral examinations diminishing dramatically and increased use of closed-question quizzes

Severe impact of Covid-19 pandemic on breast cancer care in Italy: a senonetwork national survey

Italy was the first Western country hit by the Coronavirus disease 2019 (COVID-19) pandemic, with over 246,000 documented cases and more than 35,000 deaths related to the infection as of July 26, 2020. The first documented case in Italy was reported on February 18, 2020, introducing a rapid sequence of events. A few towns near Milan and in Veneto were locked down soon thereafter. Finally, the entire country was locked down on March 9, 2020, with a national quarantine, which has severely limited the movement of the entire population except for documented work and health circumstances. Since then, many hospitals have restrained non-emergency admissions and ambulatory services, particularly for non-oncologic patients. Despite many medical and scientific reports on the current pandemic, little is known on the effect and magnitude of this health emergency on the care of patients with breast cancer

AI in board Game-Based Learning

Despite receiving less attention in educational research compared to digital games, boardgames show great potential as a learning environment in many educational scenarios. They promote acquisition of disciplinary knowledge and key competences, generate a sense of physical “togetherness”, can be employed in situation of social and economic disadvantage, and can be modified (or “modded”), for better alignment with disciplinary content. The use of games in European schools is very limited; teachers see the potential of games for learning, but their competence in the use of games for learning is superficial and limited to personal experience. High-performance AI systems such as GPT-4 have emerged as a potential game-changer in education, as a collaborative partner to assist teachers in learning design or to automatize decision-making processes. Despite known limitations, trained LLMs show promise in executing educational tasks. This study explores whether trained High-performance AI can facilitate teachers in the creation of boardgame-based learning units, by bridging their knowledge gap in game knowledge and game-based instructional skills. Using the GDBL ID model, the most comprehensive available instructional model for the creation of boardgame-based learning units, in this exploratory study we instructed Chat GPT to address two key phases of bGBL design: the choice of the game for the learning activity and the personalization of the game for constructive alignment and inclusion. Evaluation of the output by GBL experts highlights the potential of AI tools for bGB

Breast reconstruction: a quality measure for breast cancer care?

Parallel to its life-threatening nature, breast cancer can affect physical integrity, having a psychosocial impact on patients. Determining the optimal proportion of patients who should undergo breast reconstruction after cancer surgery represents a complex task. What seems to be unquestionable is that the ability to offer reconstruction and a wide range of surgical options plays an important role in current breast cancer management. The multidisciplinary approach is a paramount aspect not only for a successful oncologic treatment, but also for improving patient quality of life
