No full textApplicazione dei domini di interazione 3d per fondazioni superficiali alla progettazione definitiva di un asse autostradale
No full textIl tradizionale tema della verifica di una fondazione superficiale può essere affrontato mediante i poco diffusi, ma ormai ben noti, domini di interazione 3D. L’impiego di quest’approccio ha consentito, nell’ambito della progettazione definitiva di un asse autostradale, una verifica più rigorosa rispetto al metodo della “pressione limite” tradizionalmente utilizzato. L’obiettivo di ridurre al minimo le iterazioni tra progettista strutturale e geotecnico è stato il fattore discriminante nella scelta di questo metodo di verifica, all’interno di un progetto che prevedeva l’esecuzione di un gran numero di verifiche su diverse tipologie di opere.
Al fine di rendere possibile l’impiego professionale di tali teorie è stato inoltre necessario fornire un’interpretazione articolata delle prescrizioni delle “Nuove Norme Tecniche per le Costruzioni” 14/01/2008, specialmente per quanto concerne i coefficienti parziali γR sulle resistenze
Exploring the landscape of AI-assisted decision-making in head and neck cancer treatment: a comparative analysis of NCCN guidelines and ChatGPT responses
No full textPurpose: Recent breakthroughs in natural language processing and machine learning, exemplified by ChatGPT, have spurred a paradigm shift in healthcare. Released by OpenAI in November 2022, ChatGPT rapidly gained global attention. Trained on massive text datasets, this large language model holds immense potential to revolutionize healthcare. However, existing literature often overlooks the need for rigorous validation and real-world applicability. Methods: This head-to-head comparative study assesses ChatGPT's capabilities in providing therapeutic recommendations for head and neck cancers. Simulating every NCCN Guidelines scenarios. ChatGPT is queried on primary treatments, adjuvant treatment, and follow-up, with responses compared to the NCCN Guidelines. Performance metrics, including sensitivity, specificity, and F1 score, are employed for assessment. Results: The study includes 68 hypothetical cases and 204 clinical scenarios. ChatGPT exhibits promising capabilities in addressing NCCN-related queries, achieving high sensitivity and overall accuracy across primary treatment, adjuvant treatment, and follow-up. The study's metrics showcase robustness in providing relevant suggestions. However, a few inaccuracies are noted, especially in primary treatment scenarios. Conclusion: Our study highlights the proficiency of ChatGPT in providing treatment suggestions. The model's alignment with the NCCN Guidelines sets the stage for a nuanced exploration of AI's evolving role in oncological decision support. However, challenges related to the interpretability of AI in clinical decision-making and the importance of clinicians understanding the underlying principles of AI models remain unexplored. As AI continues to advance, collaborative efforts between models and medical experts are deemed essential for unlocking new frontiers in personalized cancer care
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Implications of seismic design aspects on a pile supported wharf structure
No full textThis paper illustrates the design issues of a pile supported wharf in a high seismicity area in Indonesia, a commonplace port structures in which the seismic response involves significant pile–slope interaction.
Pile design in high-seismicity liquefiable areas involves different aspects of earthquake geotechnical engineering with important consequences both on structural and geotechnical calculation. For the structural design, non-linear soil structure interaction (pseudo-static analysis) has been considered. Moreover, in the geotechnical design, liquefaction mitigation measures and global stability assessment have been treated.
The global stability assessment of the structure is deeply affected by simplified design methodology. In particular the hypothesis of simultaneous occurrence of maximum inertial forces and liquefaction during a seismic event is an assumption full of consequences in the current practice of geotechnical design in liquefiable soils; although international codes do not provide any specific recommendation. Such an example eventually shows very clearly that absence of precise recommendations may lead to an over conservative design
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
