Si sottolinea, inoltre, il grande impegno profuso da Maria Caltabiano tanto negli incarichi gestionali e istituzionali ricoperti presso l'Ateneo Peloritano, quanto nell'intensa attività di comunicazione delle sue ricerche rivolta alla comunità scientifica e al vasto pubblico
A term structure geostatistical model with correlated residuals: A comparative analysis
No full textThe growth of financial markets and the emerging derivative instruments require the development of advanced techniques for forecasting the term structure of interest rates. In this
context, two significant dimensions, i.e. maturity and time, need to be jointly considered in the
modeling procedure. In the literature, the Nelson–Siegel model is commonly used to explain
the dependence of the interest rates on maturity and time. However, it cannot be excluded
that the residuals obtained from Nelson–Siegel estimates are still correlated. At this purpose,
a geostatistical approach is adopted and an innovative modeling solution is provided. Indeed,
differently from the existing contributions, this paper proposes a dynamic model for predicting
the term structure of spot interest rates, where the joint evolution with respect to time and
maturity is considered for both the deterministic and the stochastic parts of the model. The
relevance as well as the potentiality of the geostatistical modeling techniques extended to
treat observations not strictly referred to a geographic system, has been properly underlined.
For comparative reasons, different hypotheses on the random field, utilized to describe the
interest rates and its trend component, are also assumed and a comparison among predictive
performance of alternative models is discussed
Overcoming the “valleys of death” in advanced therapies: The role of finance
No full textAdvanced therapies are the frontier of medical research and have a relevant therapeutic potential and a profound social value. Despite this, their funding is hindered by many heterogeneous factors that obstruct their translation and survival on the market, even when approved and effective. Using an extensive bibliometric and systematic review of 174 articles published between 2001 and 2023, this study aims to identify the factors hindering the financing of advanced therapies and suggest future research lines to overcome the biomedical and economic “valleys of death”. This study is the first review focused on advanced therapies from a financial perspective, and it contributes to advancing scientific knowledge in several ways. First, it highlights that finance academics paid little attention to the topic and most of their contributions are now outdated; therefore, there is the need to explore the new opportunities and solutions offered by financial innovation and the application of new technologies to financial activity. Second, it asks for an interdisciplinary approach to exploring advanced therapies' barriers from a holistic and process perspective and exploiting the social value generated by the development of innovative therapies. Finally, it analyzes the obstacles and value destroyed by the absence of an organic and coordinated process of public intervention, underscoring the imperative for further research to explore new public-private financial models and risk-sharing schemes and extend evaluation models by integrating financial and social value logic

No full textIl crescente impatto economico degli eventi naturali estremi in Italia e in Europa impone una riflessione sul ruolo delle politiche pubbliche e degli strumenti assicurativi nella gestione del rischio. Il nuovo sistema italiano di assicurazione obbligatoria per le imprese, introdotto con la Legge di Bilancio 2024, rappresenta una innovazione nel panorama nazionale. Questo articolo analizza le principali caratteristiche del provvedimento, ne discute le implicazioni economiche e istituzionali, e lo colloca nel
quadro più ampio delle esperienze internazionali in materia di gestione assicurativa dei disastri naturali
Exploring the Role of Voice Assistants in Managing Noncommunicable Diseases: A Systematic Review on Clinical, Behavioral Outcomes, Quality of Life, and User Experiences
Full text linkBackground: Non-communicable diseases (NCDs) represent a leading cause of global mortality, demanding innovative approaches to management. Voice assistants (VAs) have emerged as promising tools in healthcare, offering support for self-management, behavioral engagement, and patient care. This systematic review evaluates the role of VAs in NCD management, analyzing their impact on clinical and behavioral outcomes, quality of life, usability, and user experiences while identifying barriers to their adoption. Methods: A systematic search was conducted in PubMed, Scopus, and Web of Science from January 2014 to October 2024. Studies were selected based on predefined inclusion and exclusion criteria using the PRISMA guidelines. Data extraction focused on outcomes such as usability, acceptability, adherence, clinical metrics, and quality of life. The risk of bias was assessed using the Cochrane Risk of Bias (RoB) 2 and ROBINS-I tools. Results: Eight studies involving 541 participants were included, examining VAs across various NCD contexts such as diabetes, cardiovascular diseases, and mental health. While VAs demonstrated good usability and moderate adherence, their clinical and quality-of-life outcomes were modest. Behavioral improvements, such as increased physical activity and problem-solving skills, were noted in some interventions. Key challenges included privacy concerns, speech recognition errors, and accessibility issues. Conclusions: VAs show potential as supportive tools in NCD management, especially for enhancing patient engagement and self-management, and their impact on clinical outcomes and long-term usability requires further investigation. Future research should focus on diverse populations, standardized metrics, and comparative studies with alternative technologies
Battle of Water Demand Forecasting
No full textAspart of the Battle of Water Networks competition series, the Battle of Water Demand Forecasting (BWDF) was organized in the context of the 3rd Water Distribution Systems Analysis and Computing and Control in the Water Industry (WDSA-CCWI) joint conference held in Ferrara (Italy) in 2024. In line with the previous editions of the Battle of Water Networks—the main objective of which was to address a specific problem related to the design and operation of water distribution networks—the BWDF aims to compare the effectiveness of methods for the short-term forecast of urban water demand in a set of real district metered areas. During the conference, 31 teams across the world participated in the BWDF and presented their approaches. The results obtained demonstrate the importance of (1) considering integrated approaches for short-term water demand forecasting; and (2) evaluating their performance in relation to more than one metric, case study, and period
Sustainable Alternatives to Silicone in Pest Management: A Comparative Study of Biodegradable Oleogel Pheromone Dispensers for Plodia interpunctella
No full textPheromone dispensers are essential tools in integrated pest management (IPM) to reduce chemical pesticide use, particularly in food storage environments. Silicone-based dispensers (SD) are a gold standard due to their low cost and controlled pheromone release, but pose environmental/health risks related to plastic/chemicals pollution. Oleogel-based dispensers (OD) represent a biodegradable alternative, offering the advantage of pheromone incorporation during material preparation, ensuring uniform dispersion, controlled release kinetics, and reduced production steps. This study compared the performance of OD and SD over a 90-day period (at three time points: T0, T45, and T90) in attracting Plodia interpunctella. Both dispensers experienced efficacy reduction over time, but no statistically significant differences emerged between SD and OD. These results highlight OD as a promising, sustainable alternative to SD, with future work needed to optimize its formulation and validate its real-world applications
