Tempo di serie: rigenerazione. Riprese, risignificazioni, ritorni
No full textIl tempo è la sostanza della narrazione: lo è in modo evidente nelle forme della narrazione seriale, come dimostra la produzione televisiva degli ultimi venticinque anni, che ha ridisegnato le coordinate della narratività fino quasi a estenuare il campo della serialità tout court. Questo volume ragiona su questo ‘tempo di serie’ secondo un doppio vettore. In primo luogo, spinge lo sguardo oltre i confini del linguaggio cinematografico e televisivo, inquadrando la serialità come paradigma culturale. Il volume estende cioè i confini semiotici della serialità come orizzonte rappresentativo e produttivo verso un ecosistema mediale che comprende letteratura, teatro, videoarte, musica, fumetti, fotografia, animazione, moda, social, media franchise, iconologie pop, forme e pratiche di intrattenimento, artistiche e sociali. In secondo luogo, osservando questo tempo attraverso uno specifico filtro cognitivo: quello della «rigenerazione». Ripensa la serialità attraverso la metafora biologica della riproduzione e della successione (degli esseri umani, dei discorsi, dei generi, dei testi, dei prodotti culturali). E interroga la rigenerazione come motore della rappresentazione mediale, come cifra di produzione discorsiva e testuale (la creazione e ri-creazione) legata a questioni – nodali nella cultura contemporanea – come la transmedialità, la risemiotizzazione, la transcodifica, l’adattamento, l’appropriazione. Tutte forme, queste, di rigenerazione della discorsività: di linguaggi, sistemi di segni, scenari sociali e immaginari espressivi, sociotecnici e culturali
Early Prediction of the Efficacy of Local Epicardial Radiofrequency Ablation for the Robotic Treatment of Persistent Atrial Fibrillation
Full text linkBACKGROUND Early prediction of the efficacy of local epicardial radiofrequency ablation (LERFA) is crucial for optimizing the robotic treatment of persistent atrial fibrillation.
OBJECTIVE This study aimed to develop a machine learning model that accurately predicts LERFA efficacy within the first 5 seconds of the procedure, to stop ineffective procedures and reduce unnecessary cardiac tissue damage.
METHODS Impedance data from 92 patients who underwent robotic LERFA were analyzed, with a total of 2486 LERFAs included in the final dataset. LERFA efficacy predictors, including zerotime impedance value, slope, and harmonic components, were extracted from the first 5 seconds of each time-impedance curve.
Several supervised machine learning approaches were then tested to predict LERFA efficacy.
RESULTS Random Forest demonstrated the highest performance, achieving 94.5% accuracy, 88.3% sensibility, and 97.2% specificity. This Random Forest modelsignificantly outperformed the benchmark approach based on the zero-time impedance value alone, which achieved an accuracy of only 55.6% and a specificity of only 37.7%.
CONCLUSION The developed model enables fast and accurate prediction of LERFA efficacy, potentially reducing the number of completed LERFAs by 56.8%. Thisreduction resultsin minimal damage to cardiac tissue, a lower risk of complications, a reduction in operating time, and greater precision and safety in the ablation process
Beyond the gaze: “I-Thou” relationships in sightseeing bus tourism
Full text linkThis study, grounded in Martin Buber’s dialogical philosophy, investigates the potential for authentic “I-Thou”
relationships in tourism. For this purpose, we take the case of sightseeing bus tours, which are often perceived as
inherently disconnected experiences. Utilizing a mixed-method approach, including interviews with local
stakeholders and an open-ended questionnaire for residents, the findings reveal that even seemingly inauthentic
tourist experiences, like bus tours, can facilitate meaningful connections. Through a Buberian lens, the research
suggests that mutuality, openness, connectedness, and authenticity form “I-Thou” relationships in tourism. The
study offers theoretical contributions for future research in terms of a more positive outlook on tourist experiences and discusses practical implications of the finding
Assessing climate risk on the European financial system: a multi-scenario Analysis
Full text linkThis paper investigates the impact of climate risk on the stability of the European financial system, with a particular focus on both transition and physical risk dimensions. Given the long-term and uncertain nature of climate-related risks, traditional econometric methods often fall short in capturing their systemic implications. To address this challenge, we develop a scenario-based framework grounded in realistic projections consistent to the theoretical framework of the Network for Greening the Financial System ("NGFS"), encompassing three climate pathways: orderly transition, disorderly transition, and hot house world. We model the relationship between climate risk drivers, European companies, and the financial system using vine copulas, enabling a flexible representation of complex dependencies. The effects of these scenarios on financial institutions are evaluated through key risk metrics (expected return, value at risk, and expected shortfall) conditioned on each climate scenario. Our results offer insights into how climate transition risks propagate through the financial system, with practical implications for financial stability assessment and systemic risk management. The primary contribution lies in integrating both transition and physical climate risks into a coherent and tractable risk assessment framework, offering valuable tools for policymakers, regulators, and financial practitioners. Results show a significant dependence of European financial system to brown companies and, thus, sizable losses in the disorderly transition scenario
New indirect searches of Dark Matter with the GAPS experiment
Full text linkThe General AntiParticle Spectrometer (GAPS) is a long-duration ballon-borne experiment, designed to detect low-energy cosmic-ray antinuclei (below ∼ 0.25 GeV/n) as potential indirect signal of Dark Matter. Unlike traditional detection methods —relying for example on magnetic spectrometers— GAPS employs a novel approach based on the formation, de-excitation, and decay of exotic atoms, enabling the identification of antinuclei without the use of a magnet. The mission will investigate the low-energy sector of the cosmic-ray spectrum that has remained largely unexplored, allowing for a critical test of theoretical models predicting the flux of low-energy antideuterons; in addition, GAPS is expected to achieve unprecedented sensitivity to cosmic antiprotons and to provide leading sensitivity to the low-energy antihelium nuclei in the cosmic radiation. During its pre-flight campaign in Antarctica (November/December 2024), the apparatus was able to perform several muon runs for both scientific and calibration purposes. Performance studies related to the detection of this particle population at sea level are currently being conducted before the scheduled launch during the 2025/26 season
Claudio Napoleoni e la politica economica negli anni dell’impegno parlamentare (1976-1988)
Full text linkThis paper focuses on the economic policy proposals put forward by Claudio Napoleoni during his years in the Italian Parliament (1976-1988). This period was deeply marked by a loss of confidence in planning. Napoleoni approached economic policy by distinnguishing between medium- term political prospects – those that did not presuppose a departure from the capitalist mode of production and were also influenced by political contingencies such as proposals to reduce inflationary pressures or improve the management of the state budget – and long-term political prospects – those that presuppose a policy that promotes a departure from technocratic society, widening the gap between society and capitalism as much as possible. I particularly try to contextualize Napoleoni’s thoughts, taking into account his role in the Independent Left and his relationship with the Italian Communist Party
Nuevas miradas a la poesía española del siglo XXI
No full textNuevas miradas a la poesía española del siglo XXI se propone como volumen colectivo de referencia para entender los dinamismos y las tensiones emergentes no tanto de la producción lírica reciente, sino más bien de las tendencias actuales de la crítica y de la hermenéutica. Desde la pluralidad metodológica que no merma el rigor de las distintas perspectivas, estas páginas ofrecen reflexiones que interrogan el presente, superando la inercia del enfoque filológico tradicional para incorporar unas miradas renovadas a partir de la semiótica, de los estudios culturales, de la interdisciplinaridad, de la inter-/transtextualidad y de la transmedialidad
Unveiling national culture's influence on non-financial reporting: a systematic literature review
Full text linkPurpose - This study investigates how national culture influences non-financial reporting (NFR) by reviewing existing studies on the topic and proposing a research agenda. The review addresses two research questions: (1) What are the main characteristics of studies examining the influence of national culture on NFR? (2) Which themes and cultural factors have received attention and can be systematised to guide future research and address regulatory and implementation challenges?
Design/methodology/approach. We conduct a systematic literature review (SLR) of 60 academic articles indexed in Scopus from 1999 to 2024 to identify conceptually relevant themes, from which we derive a conceptual framework and avenues for future research.
Findings - The review reveals a fragmented yet growing body of literature and organises its insights into a conceptual framework based on three key stages of NFR: adoption, content and assurance. Five themes and six subthemes emerge, highlighting the recurring influence of some cultural dimensions. The review also reveals notable research gaps, including an overreliance on Hofstede's cultural framework, a lack of methodological diversity, a limited focus on strategic and governance-related disclosures and language use, and the underexplored interplay between NFR, national culture and regulatory contexts. Future research is encouraged to examine how cultural traits interact with regulation in the adoption of NFR, influence reporting quality and narratives, and affect the credibility and effectiveness of assurance practices.
Originality/value - To the best of our knowledge, this is the first SLR to focus specifically on the role of national culture in NFR. The study advances prior work on cultural influences in accounting by narrowing the focus to the NFR domain. In addition, it enriches the literature on NFR determinants by isolating national culture as a key factor. In doing so, the study lays the groundwork for future research on how cultural traits may support or challenge the effectiveness of mandatory NFR frameworks across countries
Preliminary Assessment of Self-Centring Steel Frame Systems with Energy Dissipation Devices
Full text linkThe increasing emphasis on the resilience and sustainability of the built environment in modern building construction has led to the development of low-damage solutions such as rocking systems. In this context, the Life Cycle Thinking approach is essential to ensure both structural performance and the long-term environmental and economic sustainability of design decisions. Self-centring rocking systems minimize residual deformations and structural damage, enabling rapid post-earthquake recovery while reducing repair costs and resource consumption. This study investigates the application of re-centring rocking systems in
lightweight steel structures. The focus is on the analysis of in-plane frames with controlled rocking mechanisms that include post-tensioned members and energy dissipators such as friction or viscous devices. A sensitivity analysis is performed to evaluate the structural response when different energy dissipation devices are integrated into the frame
